- gas: amend X_unsigned uses
- PR gas/30688
-
- X_unsigned being clear does not indicate a negative number; it merely
- indicates a signed one (whose sign may still be clear). Amend two uses
- by an actual value check.

- RISC-V: Add actual 'Zvkt' extension support
- The 'Zvkt' extension is listed on the added extensions in the GNU Binutils
- version 2.41 (see binutils/NEWS). However, the support of this extension
- was actually missing.
-
- This commit adds actual support of this extension and adds implications
- from 'Zvkn' and 'Zvks' superset extensions.
-
- bfd/ChangeLog:
-
- * elfxx-riscv.c (riscv_implicit_subsets) Add implications from
- 'Zvkn' and 'Zvks'. (riscv_supported_std_z_ext): Add 'Zvkt' to
- the supported extension list.

- MIPS: Support `-gnuabi64' target triplet suffix for 64-bit Linux targets
- Make the n64 ABI the default for 64-bit Linux targets specified with
- `-gnuabi64' suffix included in the target triplet, for configurations
- such as the Debian mips64el and mips64r6el ports. Adjust testsuite
- configuration accordingly.
-
- There are the following regressions with the new target triplet:
-
- mips64-linux-gnuabi64 +FAIL: readelf -S bintest
- mips64-linux-gnuabi64 +FAIL: MIPS reloc estimation 1
- mips64el-linux-gnuabi64 +FAIL: readelf -S bintest
- mips64el-linux-gnuabi64 +FAIL: MIPS reloc estimation 1
-
- The `readelf' issue comes from a difference in section headers produced
- that the `binutils/testsuite/binutils-all/readelf.s-64' pattern template
- does not match. While there has been a precedent it does not appear to
- me that there is a clear advantage from adding more and more variations
- to the template rather than forking the existing template into multiple
- ones for a more exact match. So this is best deferred to a separate
- discussion.
-
- The MIPS reloc estimation issue is an actual bug in `objdump', which
- discards a number of trailing entries from output here for n64 composed
- relocations:
-
- DYNAMIC RELOCATION RECORDS
- OFFSET TYPE VALUE
- 0000000000000000 R_MIPS_NONE *ABS*
- 0000000000000000 R_MIPS_NONE *ABS*
-
- and consequently `ld/testsuite/ld-mips-elf/reloc-estimate-1.d' does not
- match even though ELF output produced is correct according to `readelf':
-
- Relocation section '.rel.dyn' at offset 0x10400 contains 2 entries:
- Offset Info Type Sym. Value Sym. Name
- 000000000000 000000000000 R_MIPS_NONE
- Type2: R_MIPS_NONE
- Type3: R_MIPS_NONE
- 000000010000 000300001203 R_MIPS_REL32 0000000000010010 foo@@V2
- Type2: R_MIPS_64
- Type3: R_MIPS_NONE
-
- As a genuine bug this has to be handled separately.

- testsuite: Handle composed R_MIPS_NONE relocations
- MIPS n64 ABI has a peculiarity where all relocations are composed of
- three, with subsequent relocation types set to R_MIPS_NONE if further
- calculation is not required. Example output produced by `readelf' and
- `objdump' for such relocations is:
-
- Offset Info Type Sym. Value Sym. Name + Addend
- 000000000000 000800000002 R_MIPS_32 0000000000000000 foo + 0
- Type2: R_MIPS_NONE
- Type3: R_MIPS_NONE
-
- and:
-
- OFFSET TYPE VALUE
- 0000000000000000 R_MIPS_32 foo
- 0000000000000000 R_MIPS_NONE *ABS*
- 0000000000000000 R_MIPS_NONE *ABS*
-
- respectively. The presence of these extra R_MIPS_NONE entries is not
- relevant for generic or even some MIPS tests, so optionally match them
- with the respective dump patterns, also discarding `xfail' annotation
- for MIPS/OpenBSD targets from gas/elf/missing-build-notes.d, removing
- these regressions:

- MIPS/LD/testsuite: Fix `attr-gnu-4-10' failures with IRIX targets
- IRIX targets do not enable the production of a `.pdr' section in GAS by

- MIPS/LD/testsuite: Fix JALR relaxation test failure with IRIX 6
- The `mips-sgi-irix6' target only supports IRIX linker emulations, but
- most JALR relaxation tests request the relevant traditional emulation
- instead, causing a link failure:
-
- ./ld-new: unrecognised emulation mode: elf32btsmipn32
- Supported emulations: elf32bmipn32 elf32bsmip elf64bmip
-
- This is clearly an omission from the conversion to use the per-ABI
- framework made with commit 78da84f99405 ("MIPS/LD/testsuite: Correct
- mips-elf.exp test ABI/emul/endian arrangement"). These tests are also
- endianness agnostic, which was missed in the conversion as well.

- LoongArch: gas: Fix shared builds
- Formerly an include of libbfd.h was added in commit 56576f4a722
- ("LoongArch: gas: Add support for linker relaxation."), in order to
- allow calling _bfd_read_unsigned_leb128 from gas, but doing so broke
- shared builds. Commit d2fddb6d783 fixed this reference but did not
- remove the now unnecessary inclusion of libbfd.h. The gas_assert macro
- expands into a conditional call to abort(), but "abort" is re-defined to
- _bfd_abort in libbfd.h, so the extra include breaks any gas_assert
- usage, and should be removed.
-
- gas/ChangeLog:
-
- * config/tc-loongarch.c: Don't include libbfd.h.

-2023-06-30 Christoph Müllner <christoph.muellner@vrull.eu>
-
- RISC-V: Add support for the Zfa extension
- This patch adds support for the RISC-V Zfa extension,
- which introduces additional floating-point instructions:
- * fli (load-immediate) with pre-defined immediates
- * fminm/fmaxm (like fmin/fmax but with different NaN behaviour)
- * fround/froundmx (round to integer)
- * fcvtmod.w.d (Modular Convert-to-Integer)
- * fmv* to access high bits of FP registers in case XLEN < FLEN
- * fleq/fltq (quiet comparison instructions)
-
- Zfa defines its instructions in combination with the following
- extensions:
- * single-precision floating-point (F)
- * double-precision floating-point (D)
- * quad-precision floating-point (Q)
- * half-precision floating-point (Zfh)
-
- This patch is based on an earlier version from Tsukasa OI:
- https://sourceware.org/pipermail/binutils/2022-September/122939.html
- Most significant change to that commit is the switch from the rs1-field
- value to the actual floating-point value in the last operand of the fli*
- instructions. Everything that strtof() can parse is accepted and
- the '%a' printf specifier is used to output hex floating-point literals
- in the disassembly.
-
- The Zfa specification is frozen (and has passed public review). It is
- available as a chapter in "The RISC-V Instruction Set Manual: Volume 1":
- https://github.com/riscv/riscv-isa-manual/releases
-
- bfd/ChangeLog:

- LoongArch: Deprecate $v[01], $fv[01] and $x names per spec
- As outlined in the LoongArch ELF psABI spec [1], it is actually already
- 2 versions after the initial LoongArch support, and the $v[01] and
- $fv[01] names should really get sunset by now.
-
- In addition, the "$x" name for $r21 was never included in any released
- version of the ABI spec, and such usages are all fixed to say just $r21
- for every project I could think of that accepted a LoongArch port.
-
- Plus, the upcoming LSX/LASX support makes use of registers named
- "$vrNN" and "$xrNN", so having "$vN" and "$x" alongside would almost
- certainly create confusion for developers.
-
- Issue warnings for such usages per the deprecation procedure detailed
- in the spec, so we can finally remove support in the next release cycle
- after this.

-
- LoongArch: support disassembling certain pseudo-instructions
- Add a flag in the pinfo field for being able to mark certain specialized
- matchers as disassembler-only, so some degree of isolation between
- assembler-side and disassembler-side can be achieved.
-
- This isolation is necessary, firstly because some pseudo-instructions
- cannot be fully described in the opcode table, like `li.[wd]`, so the
- corresponding opcode entry cannot have meaningful match/mask values.
- Secondly, some of these pseudo-instructions can be realized in more than
- one plausible ways; e.g. `li.w rd, <something between 0 and 0x7ff>` can
- be realized on LA64 with any of `addi.w`, `addi.d` or `ori`. If we tie
- disassembly of such aliases with the corresponding GAS support, only one
- canonical form among the above would be recognized as `li.w`, and it
- would mildly impact the readability of disassembly output.
- People wanting the exact disassembly can always set `-M no-aliases` to
- get the original behavior back.
-
- In addition, in certain cases, information is irreversibly lost after
- assembling, so perfect round-trip would not be possible in such cases.
- For example, `li.w` and `li.d` of immediates within int32_t range
- produce the same code; in this patch, `addi.d rd, $zero, imm` is treated
- as `li.d`, while `addi.w` and `ori` immediate loads are shown as `li.w`,
- due to the expressible value range well within 32 bits.

- sframe: bfd: gas: ld: format bump to SFrame version 2
- SFrame version 2 encodes the size of repetitive insn block explicitly
- in the format. Add information in the SFrame FDE to convey the size
- of the block of repeating instructions. This information is used only
- for SFrame FDEs of type SFRAME_FDE_TYPE_PCMASK.
-
- Introduce two extra bytes for padding: this ensures that the memory
- accesses to the members of the SFrame Frame Descriptor Entry (FDE) are
- naturally aligned.
-
- gas generates SFrame section with version SFRAME_VERSION_2 by default.
-
- libsframe provides two new APIs to:
- - get an SFrame FDE data from the decoder context, and
- - add an SFrame FDE to the encoder context.
- The additional argument (for rep_block_size) is useful for SFrame FDEs
- where FDE type is SFRAME_FDE_TYPE_PCMASK.
-
- The linker will generate the output SFrame sections in the
- SFRAME_VERSION_2 format. If the input sections offered to the linker
- are not all in the SFRAME_VERSION_2 format, the linker issues an error
- to the user.
-
- objdump/readelf will show the following message to the user if .sframe
- section in SFRAME_VERSION_1 format is seen:
-
- "No further information can be displayed. SFrame version not
- supported."

-
- libsframe: fix sframe_find_fre for pltN entries
- For a toy application on x86_64, for example, following is the SFrame
- stack trace information for the 3 pltN entries of 16 bytes each:
-
- func idx [1]: pc = 0x401030, size = 48 bytes
- STARTPC[m] CFA FP RA
- 0000000000000000 sp+8 u u
- 000000000000000b sp+16 u u
-
- The data in first column is the start_ip_offset. Also note that the FDE
- is of type SFRAME_FDE_TYPE_PCMASK (denoted by the [m] on LHS).
-
- Where each pltN (note: excluding plt0 entry) entry looks like:
-
- 401030: jmp *0x2fca(%rip)
- 401036: push $0x0
- 40103b: jmp 401020<_init+0x20>
-
- 401040: jmp *0x2fc2(%rip)
- 401046: push $0x1
- 40104b: jmp 401020<_init+0x20>
-
- 401050: jmp *0x2fba(%rip)
- 401056: push $0x2
- 40105b: jmp 401020<_init+0x20>
-
- Now, to find SFrame stack trace information from an FDE of type
- SFRAME_FDE_TYPE_PCMASK, sframe_find_fre () was doing an operation
- like,
- (start_ip_offset & 0xf) >= (pc & 0xf)
-
- This works for pltN entry of size, say, less than 16 bytes. But if the
- pltN entries or similar code stubs (for which SFrame FDE of type
- SFRAME_FDE_TYPE_PCMASK may be used), evolve to be of size > 16 bytes,
- this will cease to work.
-
- To match the range covered by the SFrame FRE, one should instead perform
- a modulo operation. The constant for the modulo operation must be the
- size of the pltN entry. Further, this constant should ideally be
- encoded in the format, as it may be different for each ABI.
-
- In SFrame Version 2 of the format, we will move towards encoding it
- explicitly in the SFrame FDE. For now, fix up the logic to at least
- move towards modulo operation.

- bfd: Improve nm and objdump without section header
- When there is no section header in an executable or shared library, we
- reconstruct dynamic symbol table from the PT_DYNAMIC segment, which
- contains DT_HASH/DT_GNU_HASH/DT_MIPS_XHASH, DT_STRTAB, DT_SYMTAB,
- DT_STRSZ, and DT_SYMENT entries, to improve nm and objdump. For DT_HASH,
- the number of dynamic symbol table entries equals the number of chains.
- For DT_GNU_HASH/DT_MIPS_XHASH, only defined symbols with non-STB_LOCAL
- indings are in hash table. Since DT_GNU_HASH/DT_MIPS_XHASH place all
- symbols with STB_LOCAL binding before symbols with other bindings and
- all undefined symbols defined ones in dynamic symbol table, the highest
- symbol index in DT_GNU_HASH/DT_MIPS_XHASH is the highest dynamic symbol
- table index. We can also get symbol version from DT_VERSYM, DT_VERDEF
- and DT_VERNEED entries.
-
- dt_symtab, dt_versym, dt_verdef, dt_verneed, dt_symtab_count,
- dt_verdef_count, dt_verneed_count and dt_strtab are added to
- elf_obj_tdata to store dynamic symbol table information.

- Fix handling of DW_TAG_unspecified_type for Ada
- Commit 80eaec735e ("[gdb/symtab] Handle named DW_TAG_unspecified_type
- DIE") changed the handling of DW_TAG_unspecified_type. Before this
- change, such types were not entered into the symbol table.
-
- It turns out that, when such a type is in the symtab, it can cause
- failures in Ada. In particular, a private type in another package may
- be seen locally as "void".
-
- Now, it would probably be better to fix this via check_typedef.
- However, that is somewhat difficult given the state of the DWARF
- reader -- in particular with gdb_index, this would require expanding
- potentially many CUs to find the correct type.
-
- Instead, this patch changes gdb to not enter a symbol for an
- unspecified type -- but only for Ada.

- libsframe: update the semantics of sframe_fre_get_fp_offset
- Until now, sframe_fre_get_fp_offset () would return
- SFRAME_ERR_FREOFFSET_NOPRESENT if the ABI uses fixed FP offset. A stack
- tracer, then, would call an explicit sframe_decoder_get_fixed_fp_offset ()
- to get the FP offset.
-
- On second look, it appears to make sense to hide these details of
- whether the FP offset is fixed or not in an ABI from the consumer. Now,
- with the changed semantics, the call to sframe_fre_get_fp_offset () will
- fetch the fixed FP offset if applicable, or get the FP offset from FRE
- when there is no fixed FP offset.
-
- This patch changes the behavior of sframe_fre_get_fp_offset (): it turns
- an error into non-error. This change will be included with the next
- release of libsframe, where all the exposed symbols will be versioned
- with version node LIBSFRAME_1.0 for the first time.

-
- libsframe: update the semantics of sframe_fre_get_ra_offset
- Until now, sframe_fre_get_ra_offset () would return
- SFRAME_ERR_FREOFFSET_NOPRESENT if the ABI uses fixed RA offset (e.g.,
- AMD64). A stack tracer, then, will call an explicit
- sframe_decoder_get_fixed_ra_offset () to get the RA offset.
-
- On second look, it appears to make sense to hide these details of
- whether the RA offset is fixed or not from the consumer. Now, with the
- changed semantics, the call to sframe_fre_get_ra_offset () will fetch
- the fixed RA offset if applicable, or get the RA offset from FRE when
- there is no fixed RA offset.
-
- Adjustments need to be made to ensure the textual dump remains the same
- as preivous. Currently, e.g., if RA is not being tracked per FRE,
- following is seen with objdump --sframe:
-
- STARTPC CFA FP RA
- 000000000000NNNN sp+X u u
-
- This patch changes the behavior of sframe_fre_get_ra_offset: it turns an

- libsframe: remove sframe_get_funcdesc_with_addr API
- This is an incompatible ABI change in libsframe.
-
- The interface provided by this function is not a healthy abstraction to

- include/sframe.h (the SFrame binary format definition). This ties up
- the library in a undesirable way. Most importantly, this function
- should technically not be directly necessary for a stack tracer. A
- stack tracer will likely only need to do a sframe_find_fre ().

- gdb/testsuite: Avoid infinite loop in gdb.reverse/step-reverse.exp
- This testcase sometimes gets stuck in a loop for hours when running in our
- CI. The problem is that due to an issue unrelated to reverse debugging the
- inferior exits early, and because of the overly generic ".*" pattern the
- testcase keeps sending the "next" command without noticing that the
- inferior is gone.
-
- gdb_test_multiple has a pattern to detect that "The program is not being
- run.", but since it is placed after the patterns from the caller it won't
- be triggered. It also has a timeout pattern but because it is triggered
- between successful matches, each time the test matches the '-re -wrap ".*"'
- this counts as a successful match and the timeout is reset.
-
- Since the test binary is compiled with debug information, fix by changing
- one of the generic patterns to match entering the main function and the
- other one to match the source code line number that is shown by GDB right
- after the "step" command.
-
- Also, as a precaution add a maximum number of times the "next" command will
- be sent.

- [GOLD] PowerPC64 huge branch dynamic relocs
- PowerPC64 gold and ld.bfd implement an indirect branch trampoline,
- used when the destination of a branch exceeds a bounce through another
- "b" instruction. When generating PIEs or shared libraries, the
- addresses need dynamic relocations. This was implemented in gold
- using a dedicated relocation section, but this means the relative
- relocations for these addresses are not sorted properly with other
- dynamic relative relocations: gold doesn't support merging relocation
- sections, then sorting. Instead we need to use a single .rela.dyn
- section.
-
- This is done by increasing the size of rela_dyn_ during do_relax to
- account for needed dynamic relocations, delaying adding the actual
- relocations until the end of relaxation once the layout has
- stabilised.

- [gdb/testsuite] Clean or check standard_output_file dir in gdb_init
- In commit e2adba909e7 ("[gdb/testsuite] Clean up before compilation in
- gdb.ada/call-no-debug.exp") I added some code in the test-case to remove some
- files at the start of the test-case:
- ...
- remote_file host delete [standard_output_file prog.o]
- remote_file host delete [standard_output_file prog.ali]
- ...
-
- Then in commit b7b77500dc5 ("[gdb/testsuite] Clean standard_output_file dir in
- gdb_init") I tried to do this more structurally, by cleaning up the entire
- standard_output_file directory, for all test-cases.
-
- This caused a regression when using "make check -j 2", due to the cleanup
- removing the active gdb.log, so I reverted the commit.
-
- Try again, this time handling the two cases separately.
-
- If the standard_output_file directory contains an active gdb.log, check that
- the directory contains no files other than gdb.log and gdb.sum. This puts
- the reponsibility for the cleanup at the callers in gdb/testsuite/Makefile.in
- which use --outdir.
-
- If the standard_output_file directory doesn't contain an active gdb.log, clean
- it by removing the entire directory.
-
- An exception is made for performance tests, where cleaning up the
- standard_output_file dir is the wrong thing to do, because an invocation with
- GDB_PERFTEST_MODE == run is intended to reuse binaries left there by an
- earlier invocation with GDB_PERFTEST_MODE == compile.
-
- Tested on x86_64-linux.

- Implement DAP "hover" context
- A DAP client can request that an expression be evaluated in "hover"
- context, meaning that it should not cause side effects. In gdb, this
- can be implemented by temporarily setting a few "may-" parameters to
- "off".
-

- Implement DAP logging breakpoints
- DAP allows a source breakpoint to specify a log message. When this is
- done, the breakpoint acts more like gdb's dprintf: it logs a message
- but does not cause a stop.
-
- I looked into implement this using dprintf with the new %V printf
- format. However, my initial attempt at this did not work, because
- when the inferior is continued, the dprintf output is captured by the
- gdb.execute call. Maybe this could be fixed by having all
- inferior-continuation commands use the "&" form; the main benefit of
- this would be that expressions are only parsed a single time.

- Handle supportsVariablePaging in DAP
- A bug report about the supportsVariablePaging capability in DAP
- resulted in a clarification: when this capability is not present, DAP
- implementations should ignore the paging parameters to the "variables"
- request. This patch implements this clarification.
-
- Implement type checking for DAP breakpoint requests
- I realized that with a small refactoring, it is possible to type-check
- the parameters to the various DAP breakpoint requests. This would
- have caught the earlier bug involving hitCondition.
-
- Handle exceptions when creating DAP breakpoints
- When creating a DAP breakpoint, a failure should be returned by
- setting "verified" to False. gdb didn't properly implement this, and
- there was a FIXME comment to this effect. This patch fixes the
- problem.
-
- Reuse breakpoints more frequently in DAP
- The DAP breakpoint code tries to reuse a breakpoint when possible.
- Currently it uses the condition and the hit condition (aka ignore
- count) when making this determination. However, these attributes are
- just going to be reset anyway, so this patch changes the code to
- exclude these from the reuse decision.
-
- Fix type of DAP hitCondition
- DAP specifies a breakpoint's hitCondition as a string, meaning it is
- an expression to be evaluated. However, gdb implemented this as if it
- were an integer instead. This patch fixes this oversight.

- gdb/DAP Few bug fixes & Evaluate Array Watch vars
- v2.
-
- EvaluateResult does not need a name, just as what Tom pointed out in
- previous review. It's only the *children* that need to be made sure that
- their names are valid. An identifier for a variable, can't ever have an
- integer as a name, anyhow (not as far as I am aware, no programming
- languages allow for that).
-
- Removed the f-strings and use str() instead as pointed out that
- f-strings might not be supported fully.
-
- v1.
-
- This patch fixes a few bugs.
-
- First of all, name of VariableReferences must always be of string type.
- This patch makes sure that this is the case by formatting the name. If
- (when) the name is an integer, this will cause clients to fail or throw
- errors.
-
- Fixes a bug in NoOpArrayPrinter that calculated children to be N, but
- only ever retrieves N-1 children, which makes Python at some time later
- (during fetch_children -> fetch_one_child(N) ) raise an exception (out
- of list index) which makes the entire request go bad.
-
- The result[self.result_name] also f-strings the printer.to_string()
- value, because this can potentially be a LazyString (which is a Python
- object, not a string) and is not serializable by json.dumps.

- [gdb/testsuite] Reimplement Term::command_no_prompt_prefix

- ...
- command_no_prompt_prefix "tui enable"
- ...
-
- The proc command_no_prompt_prefix is documented as:
- ...
- # As proc command, but don't wait for an initial prompt. This is used for
- # initial terminal commands, where there's no prompt yet.
- ...
-
- Indeed, before the "tui enable" command, the tuiterm is empty, so there is no
- prompt and just before switching to TUI we have in the tuiterm:
- ...
- tui enable
- ...
-
- The reason that there is no prompt, is that:
- - in order for tuiterm to show something, its input processing procs need to
- be called, and
- - the initial gdb prompt, and subsequent prompts generated by gdb_test-style
- procs, are all consumed by those procs instead.
-
- This is in principle not a problem, but the absence of a prompt makes a
- tuiterm session look less like a session on an actual xterm.
-
- Add a new proc gen_prompt, that:
- - generates a prompt using echo
- - consumes the response before the prompt using gdb_expect
- - consumes the prompt using Term::wait_for "".
-
- This allows us to reimplement Term::command_no_prompt_prefix using
- Term::command, and just before switching to TUI we have in the tuiterm:

- gdb/Python: Added ThreadExitedEvent
- v6:
- Fix comments.
- Fix copyright
- Remove unnecessary test suite stuff. save_var had to stay, as it mutates
- some test suite state that otherwise fails.
-
- v5:
- Did what Tom Tromey requested in v4; which can be found here: https://pi.simark.ca/gdb-patches/87pmjm0xar.fsf@tromey.com/
-
- v4:
- Doc formatting fixed.
-
- v3:
- Eli:
- Updated docs & NEWS to reflect new changes. Added
- a reference from the .ptid attribute of the ThreadExitedEvent
- to the ptid attribute of InferiorThread. To do this,
- I've added an anchor to that attribute.
-
- Tom:
- Tom requested that I should probably just emit the thread object;
- I ran into two issues for this, which I could not resolve in this patch;
-
- 1 - The Thread Object (the python type) checks it's own validity
- by doing a comparison of it's `thread_info* thread` to nullptr. This
- means that any access of it's attributes may (probably, since we are
- in "async" land) throw Python exceptions because the thread has been
- removed from the thread object. Therefore I've decided in v3 of this
- patch to just emit most of the same fields that gdb.InferiorThread has, namely
- global_num, name, num and ptid (the 3-attribute tuple provided by
- gdb.InferiorThread.ptid).
-
- 2 - A python user can hold a global reference to an exiting thread. Thus
- in order to have a ThreadExit event that can provide attribute access
- reliably (both as a global reference, but also inside the thread exit
- handler, as we can never guarantee that it's executed _before_ the
- thread_info pointer is removed from the gdbpy thread object),
- the `thread_info *` thread pointer must not be null. However, this
- comes at the cost of gdb.InferiorThread believing it is "valid" - which means,
- that if a user holds takes a global reference to that
- exiting event thread object, they can some time later do `t.switch()` at which
- point GDB will 'explode' so to speak.
-
- v2:
- Fixed white space issues and NULL/nullptr stuff,
- as requested by Tom Tromey.
-
- v1:
- Currently no event is emitted for a thread exit.
-
- This adds this functionality by emitting a new gdb.ThreadExitedEvent.
-
- It currently provides four attributes:
- - global_num: The GDB assigned global thread number
- - num: the per-inferior thread number
- - name: name of the thread or none if not set
- - ptid: the PTID of the thread, a 3-attribute tuple, identical to
- InferiorThread.ptid attribute
-
- Added info to docs & the NEWS file as well.
-
- Added test to test suite.
-
- Fixed formatting.
-
- Feedback wanted and appreciated.

- [gdb/testsuite] Fix gdb.tui/long-prompt.exp with read1
- When running test-case gdb.tui/long-prompt.exp with check-read1, we get:
- ...
- (gdb) FAIL: gdb.tui/long-prompt.exp: prompt size == width + 1: \
- end of screen: at last line
- ...
-
- The problem is in these commands:
- ...
- Term::command "echo \\n"
- Term::command "echo \\n"
- Term::command "echo \\n"
- Term::command "echo \\n"
- ...
-
- The last one makes the terminal scroll, and the scrolling makes the expected
- output match on a different line.
-
- Fix this by replacing the sequence with a single command:
- ...
- Term::command "echo \\n\\n\\n\\n\\n\\n"
- ...
- which avoids scrolling.
-
- Tested on x86_64-linux.

- [gdb/testsuite] Fix and add prompt anchoring in tuiterm
- There is a test-case that contains a unit test for tuiterm:
- gdb.tui/tuiterm.exp.
-
- However, this only excercises the tuiterm itself, and not the functions that
- interact with it, like Term::command.
-
- Add a new test-case gdb.tui/tuiterm-2.exp that:
- - overrides proc accept_gdb_output (to be able simulate incorrect responses
- while avoiding the timeout),
- - overrides proc send_gdb (to be able to call Term::command without a gdb
- instance, such that all tuiterm input is generated by the test-case).
- - issues Term::command calls, and
- - checks whether they behave correctly.
-
- This exposes a problem in Term::command. The "prompt before command" regexp
- starts with a bit that is supposed to anchor the prompt to the border:
- ...
- set str "(^|\|)$gdb_prompt $str"
- ...
- but that doesn't work due to insufficient escaping. Fix this by adding the
- missing escape:
- ...
- set str "(^|\\|)$gdb_prompt $str"
- ...
-
- Futhermore, the "prompt after command" regexp in Term::wait_for has no
- anchoring at all:
- ...
- set prompt_wait_for "$gdb_prompt \$"
- ...
- so add that as well.

- gdb/testsuite: use proper int size for gdb.dwarf2/symbol_needs_eval*.exp
- We recently realized that symbol_needs_eval_fail.exp and
- symbol_needs_eval_timeout.exp invalidly dereference an int (4 bytes on
- x86_64) by reading 8 bytes (the size of a pointer).
-
- Here how it goes:
-
- In gdb/testsuite/gdb.dwarf2/symbol_needs_eval.c a global variable is
- defined:
-
- int exec_mask = 1;
-
- and later both tests build some DWARF using the assembler doing:
-
- set exec_mask_var [gdb_target_symbol exec_mask]
- ...
- DW_TAG_variable {
- {DW_AT_name a}
- {DW_AT_type :$int_type_label}
- {DW_AT_location {
- DW_OP_addr $exec_mask_var
- DW_OP_deref
- ...
- }
- }
-
- The definition of the DW_OP_deref (from Dwarf5 2.5.1.3 Stack Operations)
- says that "The size of the data retrieved from the dereferenced address
- is the size of an address on the target machine."
-
- On x86_64, the size of an int is 4 while the size of an address is 8.
- The result is that when evaluating this expression, the debugger reads
- outside of the `a` variable.
-
- Fix this by using `DW_OP_deref_size $int_size` instead. To achieve
- this, this patch adds the necessary steps so we can figure out what
- `sizeof(int)` evaluates to for the current target.
-
- While at it, also change the definition of the int type in the assembled
- DWARF information so we use the actual target's size for an int instead
- of the literal 4.
-
- Tested on x86_64 Linux.

- gdb/testsuite: Testing with the armflang compiler
- Currently the Fortran test suite does not run with armflang because the
- compiler detection fails. This in turn means fortran_runto_main does not
- know which main method to use to start a test case.
-
- Fortran compiler detection was added in 44d469c5f85; however, the commit
- message notes that it was not tested with armflang.
-
- This commit tests and fixes up a minor issue to get the detection
- working.
-
- The goal here is to get the tests running and preventing further
- regressions during future work. This change does not do anything to fix
- existing failures.
-
- >From what I can understand, the auto detection leverages the
- preprocessor to extract the Fortran compiler identity from the defines.
- This preprocessor output is then evaluated by the test suite to import
- these defines.
-
- In the case of armflang, this evaluation step is disrupted by the
- presence of the following warning:
-
- $ armflang -E -fdiagnostics-color=never testsuite/lib/compiler.F90 -o compiler.exp
- $ clang-13: warning: argument unused during compilation: '-fdiagnostics-color=never' [-Wunused-command-line-argument]
-
- The evaluation logic is already set up to filter this warning, but the
- prefix differs.
-
- This commit fixes the issue by updating the filter to exclude the
- armflang flavour of warning.
-
- gdb.fortran regression tests run with GNU, Intel and Intel LLVM. No
- regressions detected.
-
- The gdb.fortran test results with ACfL 23.04.1 are as follows.
-
- Before:
-
- # of expected passes 560
- # of unexpected failures 113
- # of unresolved testcases 2
- # of untested testcases 5
- # of duplicate test names 2
-
- After:
-
- # of expected passes 5388
- # of unexpected failures 628
- # of known failures 10
- # of untested testcases 8
- # of unsupported tests 5
- # of duplicate test names 5
-
- As can be seen from the above, there are now considerably more passing
- assertions.

- Add type-checking to DAP requests
- It occurred to me recently that gdb's DAP implementation should
- probably check the types of objects coming from the client. This
- patch implements this idea by reusing Python's existing type

-
- Python doesn't make it very easy to do runtime type-checking, so the

-
- The FAIL is due to:
- - the glibc object crti.o containing debug information for function

- The debug information is there due to compiling glibc using a binutils which

- I've run into a similar issue before, see commit 3fbbcf473a5 ("[gdb/testsuite]

- Permit DW_OP_GNU_uninit to be used with DW_OP_piece
- This commit implements a fix for a bug reported against GDB on
- Fedora bugzilla...
-
- https://bugzilla.redhat.com/show_bug.cgi?id=2166796
-
- The test case in that bug report involved running gdb against the 'jq'
- program (which is a command-line JSON processor) on Fedora 37. Since
- the debug info is compiler (and compile-time option) dependent, it
- won't necessarily show up in other distributions or even past or
- future versions of Fedora. (E.g. when trying the example shown below
- on Fedora 38, GDB says that the value of 'value' has been optimized
- out. I.e. it does not demonstrate the same DWARF error that can be
- see when using Fedora 37.)
-
- That said, on Fedora 37, the bug could be reproduced as follows:
-
- [kev@f37-1 ~]$ gdb jq -q -ex 'b src/util.c:415' -ex 'r </dev/null'
- Reading symbols from jq...
-
- This GDB supports auto-downloading debuginfo from the following URLs:
- <https://debuginfod.fedoraproject.org/>
- Enable debuginfod for this session? (y or [n]) y
- Debuginfod has been enabled.
- To make this setting permanent, add 'set debuginfod enabled on' to .gdbinit.
- Reading symbols from /home/kev/.cache/debuginfod_client/9d3c8b4197350a190a74972d481de32abf641aa4/debuginfo...

- 416 if (state->parser == NULL) {
- (gdb) p value
- DWARF-2 expression error: DW_OP_GNU_uninit must always be the very last op.
-
- This is undesirable - rather than output an error about the DWARF
- info, we'd prefer to see a value, even if it is uninitialized.
-
- Examination of the debuginfo showed the following:
-
- <1><468f1>: Abbrev Number: 112 (DW_TAG_subprogram)
- <468f2> DW_AT_external : 1
- <468f2> DW_AT_name : (indirect string, offset: 0x4781): jq_util_input_next_input

- <46926> DW_AT_decl_line : 414
- <46928> DW_AT_decl_column : 6
- <46929> DW_AT_type : <0x3f2>
-
- Note that there's no DW_AT_location, so I looked for an abstract origin entry:
-
- <2><2dfa0>: Abbrev Number: 90 (DW_TAG_variable)
- <2dfa1> DW_AT_abstract_origin: <0x46921>
- <2dfa5> DW_AT_location : 0x27cf1 (location list)
- <2dfa9> DW_AT_GNU_locviews: 0x27ce1
-
- (Note that the DW_AT_abstract_origin attribute's value is 0x46921 which
- is the DIE for the local variable "value".)
-
- Looking at the location list, I see:
-
- 00027cf1 v000000000000000 v000000000000000 views at 00027ce1 for:
- 000000000002f8fe 000000000002f92e (DW_OP_reg13 (r13); DW_OP_GNU_uninit; DW_OP_piece: 8; DW_OP_reg12 (r12); DW_OP_GNU_uninit; DW_OP_piece: 8)
-
- While DW_OP_GNU_uninit is not the very last op, it is the last op
- prior to DW_OP_piece. The fix involved changing the DW_OP_GNU_uninit
- case in dwarf_expr_context::execute_stack_op in gdb/dwarf2/expr.c so
- that DW_OP_GNU_uninit may appear just before DW_OP_piece.
-
- With the fix in place, attempting to print 'value' now looks like
- this:
-
- (gdb) p value
- $1 = [uninitialized] {kind_flags = 0 '\000', pad_ = 0 '\000', offset = 0,
- size = 0, u = {ptr = 0x0, number = 0}}
-
- Note that "[uninitialized]" is part of the output. (But also note
- that there's an extra space character.)
-
- I've made a new test case,
- gdb.dwarf2/DW_OP_piece_with_DW_OP_GNU_uninit.exp, by adapting an
- existing one, gdb.dwarf2/opt-out-not-implptr.exp. Since it uses the
- DWARF assembler, the test case does not depend on a specific compiler
- version or compiler options.
-
- Tested on Fedora 37 and Fedora 38.

- libsframe: testsuite: add sframe_find_fre tests for pltN entries
- Add a new test plt-findfre-1 to ensure lookup of SFrame stack trace
- information for pltN entries is correct.
-
- In this test, a dummy SFrame FDE of type SFRAME_FDE_TYPE_PCMASK is
- created. The size of the 'function code block' covered by the SFrame
- FDE is equivalent to 5 pltN entries of 16 bytes each.
-
- The test first looks up SFrame FREs for some addresses in the first pltN
- entry, followed by lookups for some addresses in the fourth pltN entry.

-
- libsframe: fix sframe_find_fre for pltN entries
- To find SFrame stack trace information from an FDE of type
- SFRAME_FDE_TYPE_PCMASK, sframe_find_fre () was doing an operation
- like,
- (start_ip_offset & 0xff) >= (pc & 0xff), etc.
-
- This is buggy and needs correction. The mask 0xff should be 0xf (to
- work for a pltN entry of size say, 16 bytes).
-
- At this time, the size of the pltN entry is implicitly assumed to be 16
- bytes by libsframe. In next version of the SFrame format, we can encode
- this information explicitly in the SFrame FDE.
-
- For now, we should fix the code to at least behave correctly for the
- generated code and the generated SFrame stack trace information for the
- pltN entries on x86_64.
-
- libsframe/
- * sframe.c (sframe_find_fre): Correct the bitmask used for
- SFrame FDEs of type SFRAME_FDE_TYPE_PCMASK.

- gdb/debuginfod: cleanup debuginfod earlier
- A GDB crash was discovered on Fedora GDB that was tracked back to an
- issue with the way that debuginfod is cleaned up.
-
- The bug was reported on Fedora 37, 38, and 39. Here are the steps to
- reproduce:
-
- 1. The file /etc/ssl/openssl.cnf contains the following lines:
-
- [provider_sect]
- default = default_sect
- ##legacy = legacy_sect
- ##
- [default_sect]
- activate = 1
-
- ##[legacy_sect]
- ##activate = 1
-
- The bug will occur when the '##' characters are removed so that the
- lines in question look like this:
-
- [provider_sect]
- default = default_sect
- legacy = legacy_sect
-
- [default_sect]
- activate = 1
-
- [legacy_sect]
- activate = 1
-
- 2. Clean up any existing debuginfod cache data:
-
- > rm -rf $HOME/.cache/debuginfod_client
-
- 3. Run GDB:
-
- > gdb -nx -q -iex 'set trace-commands on' \
- -iex 'set debuginfod enabled on' \
- -iex 'set confirm off' \
- -ex 'start' -ex 'quit' /bin/ls
- +set debuginfod enabled on
- +set confirm off
- Reading symbols from /bin/ls...
- Downloading separate debug info for /usr/bin/ls
- ... snip ...
- Temporary breakpoint 1, main (argc=1, argv=0x7fffffffde38) at ../src/ls.c:1646
- 1646 {
- +quit
-
- Fatal signal: Segmentation fault
- ----- Backtrace -----
- ... snip ...
-
- So GDB ends up crashing during exit.
-
- What's happening is that when debuginfod is initialised
- debuginfod_begin is called (this is in the debuginfod library), this
- in turn sets up libcurl, which makes use of openssl. Somewhere during
- this setup process an at_exit function is registered to cleanup some
- state.
-
- Back in GDB the debuginfod_client object is managed using this code:
-
- /* Deleter for a debuginfod_client. */
-
- struct debuginfod_client_deleter
- {
- void operator() (debuginfod_client *c)
- {
- debuginfod_end (c);
- }
- };
-
- using debuginfod_client_up
- = std::unique_ptr<debuginfod_client, debuginfod_client_deleter>;
-
- And then a global debuginfod_client_up is created to hold a pointer to
- the debuginfod_client object. As a global this will be cleaned up
- using the standard C++ global object destructor mechanism, which is
- run after the at_exit handlers.
-
- However, it is expected that when debuginfod_end is called the
- debuginfod_client object will still be in a usable state, that is, we
- don't expect the at_exit handlers to have run and started cleaning up
- the library state.
-
- To fix this issue we need to ensure that debuginfod_end is called
- before the at_exit handlers have a chance to run.
-
- This commit removes the debuginfod_client_up type, and instead has GDB
- hold a raw pointer to the debuginfod_client object. We then make use
- of GDB's make_final_cleanup to register a function that will call
- debuginfod_end.
-
- As GDB's final cleanups are called before exit is called, this means
- that debuginfod_end will be called before the at_exit handlers are
- called, and the crash identified above is resolved.
-
- It's not obvious how this issue can easily be tested for. The bug does
- not appear to manifest when using a local debuginfod server, so we'd
- need to setup something more involved. For now I'm proposing this
- patch without any associated tests.

- The problem is in cli/cli-cmds.c, in the function setting_cmd, where
- we do this:
-
- const char *a0 = (const char *) argv[0]->contents ().data ();
-
- Here argv[0] is a value* which we know is either a TYPE_CODE_ARRAY or
- a TYPE_CODE_STRING. The problem is that the above line is casting the
- value contents directly to a C-string, i.e. one that is assumed to
- have a null-terminator at the end.
-
- After the above commit this can no longer be assumed to be true. A
- string value will be represented just as it would be in the current
- language, so for Ada and Fortran the string will be an array of
- characters with no null-terminator at the end.
-
- My proposed solution is to copy the string contents into a std::string
- object, and then use the std::string::c_str() value, this will ensure
- that a null-terminator has been added.
-
- I had a check through GDB at places TYPE_CODE_STRING was used and
- couldn't see any other obvious places where this type of assumption
- was being made, so hopefully this is the only offender.
-
- Running the above test with ASan compiled in no longer gives an error.

- gdb/corelow.c: avoid repeated warnings in build_file_mappings
- When GDB opens a coredump it tries to locate and then open all files
- which were mapped in the process.
-
- If a file is found but cannot be opened with BFD (bfd_open /
- bfd_check_format fails), then a warning is printed to the user. If the
- same file was mapped multiple times in the process's address space, the
- warning is printed once for each time the file was mapped. I find this
- un-necessarily noisy.
-
- This patch makes it so the warning message is printed only once per
- file.
-
- There was a comment in the code assuming that if the file was found on
- the system, opening it (bfd_open + bfd_check_format) should always
- succeed. A recent change in BFD (014a602b86f "Don't optimise bfd_seek
- to same position") showed that this assumption is not valid. For
- example, it is possible to have a core dump of a process which had
- mmaped an IO page from a DRI render node (/dev/dri/runderD$NUM). In
- such case the core dump does contain the information that portions of
- this special file were mapped in the host process, but trying to seek to
- position 0 will fail, making bfd_check_format fail. This patch removes

- gdb/corelow.c: fix use-after-free in build_file_mappings
- In core_target::build_file_mappings, GDB tries to open files referenced
- in the core dump.
-
- The process goes like this:
-
- struct bfd *bfd = bfd_map[filename];
- if (bfd == nullptr)
- {
- bfd = bfd_map[filename]
- = bfd_openr (expanded_fname.get (), "binary");
- if (bfd == nullptr || !bfd_check_format (bfd, bfd_object))
- {
- if (bfd != nullptr)
- bfd_close (bfd);
- return;
- }
- }
- asection *sec = bfd_make_section_anyway (bfd, "load");
- ...
-
- The problem is that if bfd_check_format fails, we close the bfd but keep
- a reference to it in the bfd_map.
-
- If the same filename appears another time in the NT_FILE note, we enter
- this code again. The second time, bfd_map[filename] is not nullptr and
- we try to call bfd_make_section_anyway on an already closed BFD, which
- is a use-after-free error.
-
- This patch makes sure that the bfd is only saved in the bfd_map if it
- got opened successfully.
-
- This error got exposed by a recent change in BFD (014a602b86f "Don't
- optimise bfd_seek to same position"). Since this change, opening a
- coredump which contains mapping to some special files such as a DRI
- render node (/dev/dri/renderD$NUM) exposes the issue. This happens for
- example for processes using AMDGPU devices to offload compute tasks.

- [gdb/cli] Handle pending ^C after rl_callback_read_char for readline 7
- In commit faf01aee1d0 ("[gdb] Handle pending ^C after rl_callback_read_char")
- we handled a problem (described in detail in that commit) for readline >= 8
- using public readline functions rl_pending_signal and rl_check_signals.
-
- For readline 7 (note that we require at least readline 7 so there's no need to
- worry about readline 6), there was no fix though, because rl_check_signals was
- not available.
-
- Fix this by instead using the private readline function _rl_signal_handler.
-
- There is precedent for using private readline variables and functions, but
- it's something we want to get rid of (PR build/10723). Nevertheless, I think
- we can allow this specific instance because it's not used when building
- against readline >= 8.
-
- [ In the meanwhile, a fix was committed in the devel branch of the readline
- repo, contained in commit 8d0c439 ("rollup of changes since readline-8.2"),
- first proposed here (
- https://lists.gnu.org/archive/html/bug-readline/2022-10/msg00008.html ). ]

- _bfd_free_cached_info
- doc/bfdint.texi and comments in the aout and som code about this
- function are just wrong, and its name is not very apt. Better would
- be _bfd_mostly_destroy, and we certainly should not be saying anything
- about the possibility of later recreating anything lost by this
- function. What's more, if _bfd_free_cached_info is called when
- creating an archive map to reduce memory usage by throwing away
- symbols, the target _close_and_cleanup function won't have access to
- tdata or section bfd_user_data to tidy memory. This means most of the
- target _close_and_cleanup function won't do anything, and therefore
- sometimes will result in memory leaks.
-
- This patch fixes the documentation problems and moves most of the
- target _close_and_cleanup code to target _bfd_free_cached_info.
- Another notable change is that bfd_generic_bfd_free_cached_info is now
- defined as _bfd_free_cached_info rather than _bfd_bool_bfd_true,
- ie. the default now frees objalloc memory.

- gdb: building inferior strings from within GDB
- History Of This Patch
- =====================
-
- This commit aims to address PR gdb/21699. There have now been a
- couple of attempts to fix this issue. Simon originally posted two
- patches back in 2021:
-
- https://sourceware.org/pipermail/gdb-patches/2021-July/180894.html
- https://sourceware.org/pipermail/gdb-patches/2021-July/180896.html
-
- Before Pedro then posted a version of his own:
-
- https://sourceware.org/pipermail/gdb-patches/2021-July/180970.html
-
- After this the conversation halted. Then in 2023 I (Andrew) also took
- a look at this bug and posted two versions:
-
- https://sourceware.org/pipermail/gdb-patches/2023-April/198570.html
- https://sourceware.org/pipermail/gdb-patches/2023-April/198680.html
-
- The approach taken in my first patch was pretty similar to what Simon
- originally posted back in 2021. My second attempt was only a slight
- variation on the first.
-
- Pedro then pointed out his older patch, and so we arrive at this
- patch. The GDB changes here are mostly Pedro's work, but updated by
- me (Andrew), any mistakes are mine.
-
- The tests here are a combinations of everyone's work, and the commit
- message is new, but copies bits from everyone's earlier work.
-
- Problem Description
- ===================
-
- Bug PR gdb/21699 makes the observation that using $_as_string with
- GDB's printf can cause GDB to print unexpected data from the
- inferior. The reproducer is pretty simple:
-
- #include <stddef.h>
- static char arena[100];
-
- /* Override malloc() so value_coerce_to_target() gets a known
- pointer, and we know we"ll see an error if $_as_string() gives
- a string that isn't null terminated. */
- void
- *malloc (size_t size)
- {
- memset (arena, 'x', sizeof (arena));
- if (size > sizeof (arena))
- return NULL;
- return arena;
- }
-
- int
- main ()
- {
- return 0;
- }
-
- And then in a GDB session:
-
- $ gdb -q test
- Reading symbols from /tmp/test...
- (gdb) start
- Temporary breakpoint 1 at 0x4004c8: file test.c, line 17.
- Starting program: /tmp/test
-
- Temporary breakpoint 1, main () at test.c:17
- 17 return 0;
- (gdb) printf "%s\n", $_as_string("hello")
- "hello"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
- (gdb) quit
-
- The problem above is caused by how value_cstring is used within
- py-value.c, but once we understand the issue then it turns out that
- value_cstring is used in an unexpected way in many places within GDB.
-
- Within py-value.c we have a null-terminated C-style string. We then
- pass a pointer to this string, along with the length of this
- string (so not including the null-character) to value_cstring.
-
- In value_cstring GDB allocates an array value of the given character
- type, and copies in requested number of characters. However
- value_cstring does not add a null-character of its own. This means
- that the value created by calling value_cstring is only
- null-terminated if the null-character is included in the passed in
- length. In py-value.c this is not the case, and indeed, in most uses
- of value_cstring, this is not the case.
-
- When GDB tries to print one of these strings the value contents are
- pushed to the inferior, and then read back as a C-style string, that
- is, GDB reads inferior memory until it finds a null-terminator. For
- the py-value.c case, no null-terminator is pushed into the inferior,
- so GDB will continue reading inferior memory until a null-terminator
- is found, with unpredictable results.
-
- Patch Description
- =================
-
- The first thing this patch does is better define what the arguments
- for the two function value_cstring and value_string should represent.
- The comments in the header file are updated to describe whether the
- length argument should, or should not, include a null-character.
- Also, the data argument is changed to type gdb_byte. The functions as
- they currently exist will handle wide-characters, in which case more
- than one 'char' would be needed for each character. As such using
- gdb_byte seems to make more sense.
-
- To avoid adding casts throughout GDB, I've also added an overload that
- still takes a 'char *', but asserts that the character type being used
- is of size '1'.
-
- The value_cstring function is now responsible for adding a null
- character at the end of the string value it creates.
-
- However, once we start looking at how value_cstring is used, we
- realise there's another, related, problem. Not every language's
- strings are null terminated. Fortran and Ada strings, for example,
- are just an array of characters, GDB already has the function
- value_string which can be used to create such values.
-
- Consider this example using current GDB:
-
- (gdb) set language ada
- (gdb) p $_gdb_setting("arch")
- $1 = (97, 117, 116, 111)
- (gdb) ptype $
- type = array (1 .. 4) of char
- (gdb) p $_gdb_maint_setting("test-settings string")
- $2 = (0)
- (gdb) ptype $
- type = array (1 .. 1) of char
-
- This shows two problems, first, the $_gdb_setting and
- $_gdb_maint_setting functions are calling value_cstring using the
- builtin_char character, rather than a language appropriate type. In
- the first call, the 'arch' case, the value_cstring call doesn't
- include the null character, so the returned array only contains the
- expected characters. But, in the $_gdb_maint_setting example we do
- end up including the null-character, even though this is not expected
- for Ada strings.
-
- This commit adds a new language method language_defn::value_string,
- this function takes a pointer and length and creates a language
- appropriate value that represents the string. For C, C++, etc this
- will be a null-terminated string (by calling value_cstring), and for
- Fortran and Ada this can be a bounded array of characters with no null
- terminator. Additionally, this new language_defn::value_string
- function is responsible for selecting a language appropriate character
- type.
-
- After this commit the only calls to value_cstring are from the C
- expression evaluator and from the default language_defn::value_string.
-
- And the only calls to value_string are from Fortan, Ada, and ObjectC
- related code.

- MIPS: sync oprand char usage between mips and micromips
- We should try our best to make mips32 using the same
- oprand char with micromips. So for mips32, we use:
-
- ^ is added for 5bit sa oprand for some new DSPr2 instructions:
- APPEND, PREPEND, PRECR_SRA[_R].PH.W
- the LSB bit is 11, like RD.
- +t is removed for coprocessor 0 destination register.
- 'E' does the samething.
- +t is now used for RX oprand for MFTR/MTTR (MT ASE)
- ? is added for sel oprand for MFTR/MTTR (MT ASE)
- For mips32, the position of sel in MFTR/MTTR is same with mfc0 etc,
- while for micromips, they are different.
-
- We also add an extesion format of cftc2/cttc2/mftc2/mfthc2/mttc2/mtthc2:
- concatenating rs with rx as the index of control or data.

- MIPS: fix r6 testsuites
- Introduce
- run_dump_test_o32l
- run_dump_test_n32l
- run_dump_test_n64l
- Which use `-march=from-abi` for pre-R6 testcases,
- like micromips/mips16e etc.
-
- For cases doesn't use run_dump_test_*, we use
- -mips32r2 for micromips32
- -mips1 for mips16-32
- -march=from-abi for testcases to o32/n32/n64 both/all.
-
- Replace `addi` with `addiu` for some cases for both r6 and pre-R6.
-
- Introduce some new testcases for r6 with FPXX/FP64.
- Introduce new testcase: comdat-reloc-r6.
-
- Skip `default` in mips_arch_list_matching if triple is mipsisa*, due to:
- 1)it will cannot match mipsr6@*.d: since mips32rN/mips64rN
- will always be used, it won't be a problem.
- 2)some test think -march=mips64rN will alway true for mipsisa64rN,
- which is not true now.
-
- This patch fix testsuite for all r6-default gnu triples:
- mipsisa32r6-linux-gnu
- mipsisa32r6el-linux-gnu
- mips-img-linux-gnu
- mipsel-img-linux-gnu
- mipsisa64r6-linux-gnu
- mipsisa64r6el-linux-gnu

- MIPS: default r6 if vendor is img
- This behavior is used by downstream toolchain since 2014.
- We also set the default ABI for mips*-img-elf to O32.
- The previous value is NO_ABI, which is not good default ABI.
-
- We don't support mips64*-img* due to GCC doesn't support it,
- and We believe that the multilib should be used for this case.

- MIPS: gas: alter 64 or 32 for mipsisa triples if march is implicit
- When configure with triples mipsisa[32,64]rN[el,], the march value
- is pinned to a fix value if not given explicitly. for example
- 1) mipsisa32r6-linux-gnu -n32 xx.s will complains that:
- -march=mips32r6 is not compatible with the selected ABI
- 2) mipsisa64r2el-linux-gnu -o32 generates objects with 64bit CPU:
- ELF 32-bit LSB relocatable, MIPS, MIPS64 rel2 version 1 (SYSV)
- They are not good default behaviors: Let's alter the CPU info
-
- Since we are using these triples as a regular linux distributions,
- let's alter march according to ABI.

- Harden PowerPC64 OPD handling against fuzzers
- PowerPC64 ELFv1 object files should have at most one .opd section, and
- OPD handling in elf64-ppc.c makes use of this fact by caching some
- .opd section info in the per-object bfd.tdata. This was done to avoid
- another word in the target specific section data. Of course, fuzzers
- don't respect the ABI, and even non-malicious users can accidentally
- create multiple .opd sections. So it is better to avoid possible
- buffer overflows and other confusion when OPD handling for a second
- .opd section references data for the first .opd section, by keeping
- the data per-section.
-
- The patch also fixes a memory leak, and a corner case where I think we
- could hit an assertion in opd_entry_value or read out of bounds in
- ppc64_elf_branch_reloc doing a final link producing non-ppc64 output.
- (It's a really rare corner case because not only would you need to be
- linking ppc64 objects to non-ppc64 output, you'd also need a branch
- reloc symbol to be defined in a .opd section of a non-ppc64 input.)

- bfd_close and target free_cached_memory
- bfd_free_cached_info is used in just one place in archive.c, which
- means most times we reach bfd_close the function isn't called. On the

- [gdb/tui] Fix fingerprint for cmd-only layout
- I added a cmd-only layout:
- ...
- (gdb) tui new-layout cmd cmd 1
- ...
- and set it:
- ...
- (gdb) layout cmd
- ...
- which gave me the expect result: only the cmd window in the screen.
-
- However, after going back to layout src:
- ...
- (gdb) layout src
- ...
- I got a source window with only one line in it, and the cmd window taking most
- of the screen.
-
- I traced this back to tui_set_layout, where for both the old and the new
- layout the fingerprint of the cmd window in the layout is taken. If the
- fingerprint is the same, an effort will be done to preserve the command
- window size.
-
- The fingerprint is "VC" for both the old (cmd) and new (src) layouts, which
- explains the behaviour.
-
- I think this is essentially a bug in the finger print calculation, and it
- should be "C" for the cmd layout.
-
- Fix this by not adding a V or H in the fingerprint if the list size is one.
-
- Tested on x86_64-linux.

- gdb: add support for %V to printf command
- This commit adds a new format for the printf and dprintf commands:
- '%V'. This new format takes any GDB expression and formats it as a
- string, just as GDB would for a 'print' command, e.g.:
-
- (gdb) print a1
- $a = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20}
- (gdb) printf "%V\n", a1
- {2, 4, 6, 8, 10, 12, 14, 16, 18, 20}
- (gdb)
-
- It is also possible to pass the same options to %V as you might pass
- to the print command, e.g.:
-
- (gdb) print -elements 3 -- a1
- $4 = {2, 4, 6...}
- (gdb) printf "%V[-elements 3]\n", a1
- {2, 4, 6...}
- (gdb)
-
- This new feature would effectively replace an existing feature of GDB,
- the $_as_string builtin convenience function. However, the
- $_as_string function has a few problems which this new feature solves:
-
- 1. $_as_string doesn't currently work when the inferior is not
- running, e.g:
-
- (gdb) printf "%s", $_as_string(a1)
- You can't do that without a process to debug.
- (gdb)
-
- The reason for this is that $_as_string returns a value object with
- string type. When we try to print this we call value_as_address,
- which ends up trying to push the string into the inferior's address
- space.
-
- Clearly we could solve this problem, the string data exists in GDB, so
- there's no reason why we have to push it into the inferior, but this
- is an existing problem that would need solving.
-
- 2. $_as_string suffers from the fact that C degrades arrays to
- pointers, e.g.:
-
- (gdb) printf "%s\n", $_as_string(a1)
- 0x404260 <a1>
- (gdb)
-
- The implementation of $_as_string is passed a gdb.Value object that is
- a pointer, it doesn't understand that it's actually an array. Solving
- this would be harder than issue #1 I think. The whole array to
- pointer transformation is part of our expression evaluation. And in
- most cases this is exactly what we want. It's not clear to me how
- we'd (easily) tell GDB that we didn't want this reduction in _some_
- cases. But I'm sure this is solvable if we really wanted to.
-
- 3. $_as_string is a gdb.Function sub-class, and as such is passed
- gdb.Value objects. There's no super convenient way to pass formatting
- options to $_as_string. By this I mean that the new %V feature
- supports print formatting options. Ideally, we might want to add this
- feature to $_as_string, we might imagine it working something like:
-
- (gdb) printf "%s\n", $_as_string(a1,
- elements = 3,
- array_indexes = True)
-
- where the first item is the value to print, while the remaining
- options are the print formatting options. However, this relies on
- Python calling syntax, which isn't something that convenience
- functions handle. We could possibly rely on strictly positional
- arguments, like:
-
- (gdb) printf "%s\n", $_as_string(a1, 3, 1)
-
- But that's clearly terrible as there's far more print formatting
- options, and if you needed to set the 9th option you'd need to fill in
- all the previous options.
-
- And right now, the only way to pass these options to a gdb.Function is
- to have GDB first convert them all into gdb.Value objects, which is
- really overkill for what we want.
-
- The new %V format solves all these problems: the string is computed
- and printed entirely on the GDB side, we are able to print arrays as
- actual arrays rather than pointers, and we can pass named format
- arguments.
-
- Finally, the $_as_string is sold in the manual as allowing users to
- print the string representation of flag enums, so given:
-
- enum flags
- {
- FLAG_A = (1 << 0),
- FLAG_B = (1 << 1),
- FLAG_C = (1 << 1)
- };
-
- enum flags ff = FLAG_B;
-
- We can:
-
- (gdb) printf "%s\n", $_as_string(ff)
- FLAG_B
-
- This works just fine with %V too:
-
- (gdb) printf "%V\n", ff
- FLAG_B
-
- So all functionality of $_as_string is replaced by %V. I'm not
- proposing to remove $_as_string, there might be users currently
- depending on it, but I am proposing that we don't push $_as_string in
- the documentation.
-
- As %V is a feature of printf, GDB's dprintf breakpoints naturally gain
- access to this feature too. dprintf breakpoints can be operated in
- three different styles 'gdb' (use GDB's printf), 'call' (call a
- function in the inferior), or 'agent' (perform the dprintf on the
- remote).
-
- The use of '%V' will work just fine when dprintf-style is 'gdb'.
-
- When dprintf-style is 'call' the format string and arguments are
- passed to an inferior function (printf by default). In this case GDB
- doesn't prevent use of '%V', but the documentation makes it clear that
- support for '%V' will depend on the inferior function being called.
-
- I chose this approach because the current implementation doesn't place
- any restrictions on the format string when operating in 'call' style.
- That is, the user might already be calling a function that supports
- custom print format specifiers (maybe including '%V') so, I claim, it
- would be wrong to block use of '%V' in this case. The documentation
- does make it clear that users shouldn't expect this to "just work"
- though.
-
- When dprintf-style is 'agent' then GDB does no support the use of
- '%V' (right now). This is handled at the point when GDB tries to
- process the format string and send the dprintf command to the remote,
- here's an example:
-
- Reading symbols from /tmp/hello.x...
- (gdb) dprintf call_me, "%V", a1
- Dprintf 1 at 0x401152: file /tmp/hello.c, line 8.
- (gdb) set sysroot /
- (gdb) target remote | gdbserver --once - /tmp/hello.x
- Remote debugging using | gdbserver --once - /tmp/hello.x
- stdin/stdout redirected
- Process /tmp/hello.x created; pid = 3088822
- Remote debugging using stdio
- Reading symbols from /lib64/ld-linux-x86-64.so.2...
- (No debugging symbols found in /lib64/ld-linux-x86-64.so.2)
- 0x00007ffff7fd3110 in _start () from /lib64/ld-linux-x86-64.so.2
- (gdb) set dprintf-style agent
- (gdb) c
- Continuing.
- Unrecognized format specifier 'V' in printf
- Command aborted.
- (gdb)
-
- This is exactly how GDB would handle any other invalid format
- specifier, for example:
-
- Reading symbols from /tmp/hello.x...
- (gdb) dprintf call_me, "%Q", a1
- Dprintf 1 at 0x401152: file /tmp/hello.c, line 8.
- (gdb) set sysroot /
- (gdb) target remote | gdbserver --once - /tmp/hello.x
- Remote debugging using | gdbserver --once - /tmp/hello.x
- stdin/stdout redirected
- Process /tmp/hello.x created; pid = 3089193
- Remote debugging using stdio
- Reading symbols from /lib64/ld-linux-x86-64.so.2...
- (No debugging symbols found in /lib64/ld-linux-x86-64.so.2)
- 0x00007ffff7fd3110 in _start () from /lib64/ld-linux-x86-64.so.2
- (gdb) set dprintf-style agent
- (gdb) c
- Continuing.
- Unrecognized format specifier 'Q' in printf
- Command aborted.
- (gdb)
-
- The error message isn't the greatest, but improving that can be put
- off for another day I hope.

- struct interp. Add a interps_notify_signal_received function that loops
- over all UIs and calls the signal_received method on the interpreter.
- Finally, add a notify_signal_received function that calls
- interps_notify_signal_received and then notifies the observers. Replace
- all existing notifications to the signal_received observers with calls
- to notify_signal_received.
-
- Before this patch, the CLI and MI code both register a signal_received
- observer. These observer go over all UIs, and, for those that have a
- interpreter of the right kind, print the stop notifiation.
-
- After this patch, we have just one "loop over all UIs", inside
- interps_notify_signal_received. Since the interp::on_signal_received
- method gets called once for each interpreter, the implementations only
- need to deal with the current interpreter (the "this" pointer).
-
- The motivation for this patch comes from a future patch, that makes the
- amdgpu code register an observer to print a warning after the CLI's
- signal stop message. Since the amdgpu and the CLI code both use
- observers, the order of the two messages is not stable, unless we define
- the priority using the observer dependency system. However, the
- approach of using virtual methods on the interpreters seems like a good
- change anyway, I think it's more straightforward and simple to
- understand than the current solution that uses observers. We are sure
- that the amdgpu message gets printed after the CLI message, since
- observers are notified after interpreters.
-
- Keep the signal_received, even if nothing uses if, because we will be
- using it in the upcoming amdgpu patch implementing the warning described
- above.

- [gdb] Mention --with/without-system-readline for --configuration
- Simon reported that the new test-case gdb.tui/pr30056.exp fails with system
- readline.
-
- This is because the test-case requires a fix in readline that's present in our
- in-repo copy of readline, but most likely not in any system readline yet.
-
- Fix this by:
- - mentioning --with-system-readline or --without-system-readline in the
- configuration string.
- - adding a new proc with_system_readline that makes this information available
- in the testsuite.
- - using this in test-case gdb.tui/pr30056.exp to declare it unsupported for
- --with-system-readline.

- [gdb/testsuite] Fix linefeed scrolling in tuiterm
- I came across a bug in the implementation of line feed in tuiterm, and added a
- unit test that exposes it.
-
- Before sending the line feed we have:
- ...
- Screen Dump (size 8 columns x 4 rows, cursor at column 0, row 3):
- 0 abcdefgh
- 1 ijklmnop
- 2 qrstuvwx
- 3 yz01234
- ...
- and after it we have:

- 0 ijklmnop
- 1 qrstuvwx
- 2 yz01234
- 3 yz01234
- ...
-
- Note how the cursor started at row 3 and after the line feed ended up at
- row 1, while it should have stayed in row 3.
-
- Fix this by moving "incr _cur_row -1" one level up in the loop nest in
- proc _ctl_0x0a.

- gdb/mi: fix ^running record with multiple MI interpreters
- I stumbled on the mi_proceeded and running_result_record_printed
- globals, which are shared by all MI interpreter instances (it's unlikely
- that people use multiple MI interpreter instances, but it's possible).
- After poking at it, I found this bug:
-
- 1. Start GDB in MI mode
- 2. Add a second MI interpreter with the new-ui command
- 3. Use -exec-run on the second interpreter
-
- This is the output I get on the first interpreter:
-
- =thread-group-added,id="i1"
- ~"Reading symbols from a.out...\n"
- ~"New UI allocated\n"
- (gdb)
- =thread-group-started,id="i1",pid="94718"
- =thread-created,id="1",group-id="i1"
- ^running
- *running,thread-id="all"
-
- And this is the output I get on the second intepreter:
-
- =thread-group-added,id="i1"
- (gdb)
- -exec-run
- =thread-group-started,id="i1",pid="94718"
- =thread-created,id="1",group-id="i1"
- *running,thread-id="all"
-
- The problem here is that the `^running` reply to the -exec-run command
- is printed on the wrong UI. It is printed on the first one, it should
- be printed on the second (the one on which we sent the -exec-run).
-
- What happens under the hood is that captured_mi_execute_command, while
- executing a command for the second intepreter, clears the
- running_result_record_printed and mi_proceeded globals.
- mi_about_to_proceed then sets mi_proceeded. Then, mi_on_resume_1 gets
- called for the first intepreter first. Since the
-
- !running_result_record_printed && mi_proceeded
-
- condition is true, it prints a ^running, and sets
- running_result_record_printed. When mi_on_resume_1 gets called for the
- second interpreter, running_result_record_printed is already set, so
- ^running is not printed there.
-
- It took me a while to understand the relationship between these two
- variables. I think that in the end, this is what we want to track:
-
- 1. When executing an MI command, take note if that command causes a
- "proceed". This is done in mi_about_to_proceed.
- 2. In mi_on_resume_1, if the command indeed caused a "proceed", we want
- to output a ^running record. And we want to remember that we did,
- because...
- 3. Back in captured_mi_execute_command, if we did not output a
- ^running, we want to output a ^done.
-
- Moving those two variables to the mi_interp struture appears to fix it.
- Only for the interpreter doing the -exec-run command does the
- running_result_record_printed flag get cleared, and therefore only or
- that one does the ^running record get printed.
-
- Add a new test for this, that does pretty much what the reproducer above
- shows. Without the fix, the test fails because
- mi_send_resuming_command_raw never sees the ^running record.

- [readline] Fix double free in _rl_scxt_dispose
- Consider the following scenario. We start gdb in TUI mode:
- ...
- $ gdb -q -tui
- ...
- and type ^R which gives us the reverse-isearch prompt in the cmd window:
- ...
- (reverse-i-search)`':
- ...
- and then type "foo", right-arrow-key, and ^C.
-
- In TUI mode, gdb uses a custom rl_getc_function tui_getc.
-
- When pressing the right-arrow-key, tui_getc:
- - attempts to scroll the TUI src window, without any effect, and
- - returns 0.
-
- The intention of returning 0 is mentioned here in tui_dispatch_ctrl_char:
- ...
- /* We intercepted the control character, so return 0 (which readline
- will interpret as a no-op). */
- return 0;
- ...
-
- However, after this 0 is returned by the rl_read_key () call in
- _rl_search_getchar, _rl_read_mbstring is called, which incorrectly interprets
- 0 as the first part of an utf-8 multibyte char, and tries to read the next
- char.
-
- In this state, the ^C takes effect and we run into a double free because
- _rl_isearch_cleanup is called twice.
-
- Both these issues need fixing independently, though after fixing the first we
- no longer trigger the second.
-
- The first issue is caused by the subtle difference between:
- - a char array containing 0 chars, which is zero-terminated, and
- - a char array containing 1 char, which is zero.
-
- In mbrtowc terms, this is the difference between:
- ...
- mbrtowc (&wc, "", 0, &ps);
- ...
- which returns -2, and:
- ...
- mbrtowc (&wc, "", 1, &ps);
- ...
- which returns 0.
-
- Note that _rl_read_mbstring calls _rl_get_char_len without passing it an
- explicit length parameter, and consequently it cannot distinguish between the
- two, and defaults to the "0 chars" choice.
-
- Note that the same problem doesn't exist in _rl_read_mbchar.
-
- Fix this by defaulting to the "1 char" choice in _rl_get_char_len:
- ...
- - if (_rl_utf8locale && l > 0 && UTF8_SINGLEBYTE(*src))
- + if (_rl_utf8locale && l >= 0 && UTF8_SINGLEBYTE(*src))
- ...
-
- The second problem happens when the call to _rl_search_getchar in
- _rl_isearch_callback returns. At that point _rl_isearch_cleanup has already
- been called from the signal handler, but we proceed regardless, using a cxt
- pointer that has been freed.
-
- Fix this by checking for "RL_ISSTATE (RL_STATE_ISEARCH)" after the call to
- _rl_search_getchar:
- ...
- c = _rl_search_getchar (cxt);
- + if (!RL_ISSTATE (RL_STATE_ISEARCH))
- + return 1;
- ...
-
- Tested on x86_64-linux.

- [PR ld/22263][PR ld/25694] RISC-V: Avoid dynamic TLS relocs in PIE.
- Lots of targets already fixed the TEXTREL problem for TLS in PIE.
-
- * For PR ld/25694,
- In the check_reloc, refer to spare and loongarch, they don't need to reserve
- any local dynamic reloc for TLS LE in pie/pde, and similar to other targets.
- So it seems like riscv was too conservative to estimate the TLS LE before.
- Just break and don't goto static_reloc for TLS LE in pie/pde can fix the
- TEXTREL problem.
-
- * For PR ld/22263,
- The risc-v code for TLS GD/IE in the relocate_section seems same as MIPS port.
- So similar to MIPS, pr22570, commits 9143e72c6d4d and 1cb83cac9a89, it seems
- also the right way to do the same thing for risc-v.
-
- On risc-v, fixes
- FAIL: Build pr22263-1
-
- RISC-V haven't supported the TLS transitions, so will need the same fix (use
- bfd_link_dll) in the future.

- before.

- Add a test-case that sets a prompt with color in TUI.
-
- The line containing the prompt is shown by get_line_with_attrs as follows:
- ...
- <fg:31>(gdb) <fg:default>
- ...
-
- The 31 means red, but only for foreground colors, for background colors 41
- means red.
-
- Make this more readable by using color names for both foreground and
- background, such that we have instead:
- ....
- <fg:red>(gdb) <fg:default>
- ...
-
- Tested on x86_64-linux.

- iamcu: suppress tests which can't possibly work
- With neither --32 nor --64 passed to gas, advanced features like AVX
- aren't available without explicitly enabling them.
-
- x86-64: improve gas diagnostic when no 32-bit target is configured
- Make this similar to --64 and --x32: Check whether a suitable target
- exists.
-
- x86-64: conditionalize tests using --32
- Using this option doesn't really work when no support for any 32-bit
- target was configured in (as is the case for at least cloudabi and
- rdos).
-
- x86: split gas testsuite .exp file
- The set of 32-bit-only and 64-bit-only tests has grown quite large. In
- particular when one's after only the results for the 64-bit set, having
- them live in a separate .exp file is easier / faster.
-
- x86: convert two pointers to (indexing) integers
- This in particular reduces the number of pointers to non-const that we
- have (and that could potentially be used for undue modification of
- state). As a result, fetch_code()'s 2nd parameter can then also become
- pointer-to-const.

- Fix scoped_value_mark not working with empty value chain
- The scoped_value_mark helper class was setting its internal
- mark value to NULL to indicate that the value chain had already
- been freed to mark.
-
- However, value_mark() also returns NULL if the value chain is
- empty at the time of call.
-
- This lead to the situation that if the value chain was empty
- at the time the scoped_value_mark was created, the class
- would not correctly clean up the state when it was destroyed,
- because it believed it had already been freed.
-
- I noticed this because I was setting a watchpoint very early
- in my debug session, and it was becoming a software watchpoint
- rather than hardware. Running any command that called evaluate()
- beforehand (such as 'x 0') would mean that a hardware watchpoint
- was correctly used. After some careful examination of the
- differences in execution, I noticed that values were being freed
- later in the 'bad case', which lead me to notice the issue with
- scoped_value_mark.

-
- gdb_test_multiple "" "interrupt arrived" {
- -re "Program received signal SIGINT, Interrupt\\.\r\n" {
- pass $gdb_test_name
- }
- }
-
- The problem here is that the first interrupt will trigger the prompt
- to be printed, and then, after some time the inferior will be
- interrupted.
-
- However the default pattern for gdb_test includes a '$' end anchor.
- If expect sees the prompt with nothing following it then everything is
- fine, and the test passes.
-
- However, if the interrupt is quick and so what expect sees is this:
-
- (gdb)
- Program received signal SIGINT, Interrupt.
- 0x00007ffff7d501e7 in nanosleep () from /lib64/libc.so.6

- gdb/cli-out.c: clear_current_line shouldn't trigger pagination prompt
- clear_current_line overwrites the current line with chars_per_line
- blank spaces. Printing the final space triggers a condition in
- pager_file::puts that causes lines_printed to be incremented. If
- lines_printed becomes greater than or equal to lines_allowed, the
- pagination prompt will appear if enabled.
-
- In this case the prompt is unnecessary since after printing the final
- space clear_current_line immediately moves the cursor to the beginning
- of the line with '\r'. A new line isn't actually started, so the prompt
- ends up being spurious.
-
- Additionally it's possible for gdb to crash during this pagination prompt.
- Answering the prompt with 'q' throws an exception intended to bring gdb
- back to the main event loop. But since commit 0fea10f32746,
- clear_current_line may be called under the progress_update destructor.
- The exception will try to propagate through the destructor, causing an abort.
-
- To fix this, pagination is disabled for the duration for clear_current_line.
- clear_current_line is also renamed to clear_progress_notify to help
- indicate that it is a special purpose function intended for use with
- do_progress_notify.

- PR30437 aarch64: make RELA relocs idempotent
- normally RELA relocs in BFD should not consider the contents of the
- relocated place. The aarch64 psABI is even stricter, it specifies
- (section 5.7.16) that all RELA relocs _must_ be idempotent.
-
- Since the inception of the aarch64 BFD backend all the relocs have a
- non-zero src_mask, and hence break this invariant. It's normally not
- a very visible problem as one can see it only when the relocated place
- already contains a non-zero value, which usually only happens sometimes
- when using 'ld -r' (or as in the testcase when jumping through hoops to
- generate the relocations). Or with alternative toolchains that do encode
- stuff in the relocated places with the assumption that a relocation
- to that place ignores whatever is there (as they can according to
- the psABI).
-
- Golang is such a toolchain and https://github.com/golang/go/issues/39927
- is ultimately caused by this problem: the testcase testGCData failing
- is caused by the garbage collection data-structure to describe a type
- containing pointers to be wrong. It's wrong because a field that's
- supposed to contain a file-relative offset (to some gcbits) has a
- relocation applied and that relocation has an addend which also is
- already part of the go-produced object file (so the addend is
- implicitely applied twice).

- gdb/testsuite: change hardcoded assembly in gdb.arch/disp-step-insn-reloc.exp
- When testing gdb.arch/disp-step-insn-reloc.exp with clang in an x86_64
- machine, the compiled test case would segfault when returning from
- the function can_relocate_call, with a suggestion of a broken stack.
- The example assembly in the commment was the following:
-
- f:
- MOV $1, %[ok]
- JMP end
- set_point0:
- CALL f ; tracepoint here.
- end:
-
- And the segmentation fault happening at the final "ret" instruction of
- can_relocate_call. Looking at the disassembled version of the later
- half of the important function, we see:
-
- Clang version (f starting at 11a4):
- 00000000000011ae <set_point0>:
- 11ae: e8 f1 ff ff ff callq 11a4 <can_relocate_call+0x14>
- 11b3: 89 45 fc mov %eax,-0x4(%rbp)

- 11d4: c3 retq
- 11d5: 66 66 2e 0f 1f 84 00 data16 nopw %cs:0x0(%rax,%rax,1)
- 11dc: 00 00 00 00
-
- gcc version (f starting at 401125):
- 000000000040112c <set_point0>:
- 40112c: e8 f4 ff ff ff callq 401125 <can_relocate_call+0x11>
- 401131: 89 45 fc mov %eax,-0x4(%rbp)

- 401138: 75 07 jne 401141 <set_point0+0x15>

- 40113f: eb 05 jmp 401146 <set_point0+0x1a>
- 401141: e8 c7 ff ff ff callq 40110d <fail>
- 401146: 90 nop
- 401147: c9 leaveq
- 401148: c3 retq
-
- The epilogue of set_point0 (11cf for clang, 401146 for gcc) is the main
- difference: GCC's version uses the leaveq instruction, which resets rsp
- based on rbp, while clang adds the same constant to rsp that it
- subtracted in the prologue. Clang fails because the return address that
- is added by the "call f" instruction isn't accounted for.
-
- This commit fixes that by adding a return instruction to f, which leaves
- the rsp as the compilers would expect.

- Therefore the second call to lookup_cmd () at line 697 fails to find

-
- This commit addresses this particular problem by creating a *copy* of
- original command string for the sole purpose of using it after command
- execution to lookup the command again. It may not be the most efficient
- way but it's safer given that command buffer is shared and overwritten
- in hard-to-foresee situations.

- gdb: Remove redundant frame switching
- 547ce8f00b fixed an issue where dynamic types were not being resolved
- correctly prior to printing a value. The same issue was discovered when
- printing the value using mi-mode, which was not covered by the fix.
- Porting the fix to the mi-mode code path resolved the issue.
-
- However, it was discovered that a later patch series, ending
- 2fc3b8a4cb8, independently fixed the issue in both the cli- and mi-mode
- code paths, making the original fix unneeded.
-
- This commit removes this extra frame switch and adds test coverage for
- the mi-mode scenario to protect against any future divergence in this
- area.

- gdb: safety checks in skip_prologue_using_sal
- While working on the previous patch I reverted this commit:
-
- commit e86e87f77fd5d8afb3e714f1d9e09e0ff5b4e6ff
- Date: Tue Nov 28 16:23:32 2006 +0000

- * symtab.c (find_pc_sect_line): Do not return a line before
- the start of a symtab.
-
- When I re-ran the testsuite I saw some GDB crashes in the tests:
-
- gdb.dwarf2/dw2-line-number-zero.exp
- gdb.dwarf2/dw2-lines.exp
- gdb.dwarf2/dw2-vendor-extended-opcode.exp
-
- GDB was reading beyond the end of an array in the function
- skip_prologue_using_sal.
-
- Now, without the above commit reverted I don't believe that this
- should ever happen. Reverting the above commit effectively breaks
- GDB's symtab_and_line lookup, we try to find a result for an address,
- and return the wrong symtab and line-table. In
- skip_prologue_using_sal we then walk the line table looking for an
- appropriate entry, except we never find one, and GDB just keeps going,
- wandering off the end of the array.
-
- However, I think adding extra protection to prevent walking off the
- end of the array is pretty cheap, and if something does go wrong in
- the future then this should prevent a random crash.
-
- Obviously, I have no reproducer for this, as I said, I don't think
- this should impact GDB at all, this is just adding a little extra
- caution.

- gdb/testsuite: test for a function with no line table
- This commit adds a test for the following commit:
-
- commit e86e87f77fd5d8afb3e714f1d9e09e0ff5b4e6ff
- Date: Tue Nov 28 16:23:32 2006 +0000
-
- * symtab.c (find_pc_sect_line): Do not return a line before
- the start of a symtab.
-
- We have been carrying a test for that commit in the Fedora GDB tree
- since that commit was added to GDB. I don't know why the test wasn't
- added along with the original commit, but as was written, the test is
- pretty gross, it uses objcopy to pull the .text section from an object
- file, which was then injected into another source file within a .asm
- statement...
-
- ... these days we can just make use of the DWARF assembler to achieve
- the same results, so I've rewritten the test and think it is worth
- adding this to upstream GDB.
-
- The original patch was about about how we find the best symtab and
- line table entry, and what to do when GDB can't find a good match.
-
- The new test creates a CU with two functions, only one of which is
- covered by the line table. With the above patch reverted GDB returns
- an invalid address.
-
- With the above patch reverted I did run the testsuite to see what
- other tests might already be exercising this functionality, and I
- found two tests:
-
- gdb.dwarf2/dw2-step-out-of-function-no-stmt.exp
- gdb.dwarf2/dw2-vendor-extended-opcode.exp
-
- These are pretty similar, they either create minimal, or no line table
- for one of the functions in the source file, and as a consequence GDB
- returns an unexpected address at some point during the test.
-
- However, both of those tests are really focused on other issues, so I
- think this new test does add some value. Plus the new test is not
- large, so it's not a huge cost to also run this new test.

- gdb/breakpoint: use warning function instead of gdb_printf
- Noticed that in breakpoint.c, in one place, we do this:
-
- gdb_printf (_("warning: Error removing "
- "breakpoint %d\n"),
- old_loc->owner->number);
-
- Instead of using the `warning` function. There are a number of
- differences between using gdb_printf like this and calling `warning`,
- the main one is probably that real warnings are sent to gdb_stderr,
- while the above gdb_printf call will go to gdb_stdout.
-
- In this commit I:
-
- 1. Change to call `warning`, we can drop the "warning: " prefix from
- the string in breakpoint.c,
-
- 2. Update the warning text, I now start with a lower case 'e', which

- x86: further adjust extend-to-32bit-address conditions
- While a442cac5084e ("ix86: wrap constants") helped address a number of
- inconsistencies between BFD64 and !BFD64 builds, it has also resulted in
- certain bogus uses of constants to no longer be warned about. Leverage
- the md_optimize_expr() hook to adjust when to actually truncate
- expressions to 32 bits - any involvement of binary expressions (which
- would be evaluated in 32 bits only when !BFD64) signals the need for
- doing so. Plain constants (or ones merely subject to unary operators)
- should remain un-truncated - they would be handled as bignums when
- !BFD64, and hence are okay to permit.
-
- To compensate
- - slightly extend optimize_imm() (to be honest I never understood why
- the code being added - or something similar - wasn't there in the
- first place),
- - adjust expectations of the disp-imm-32 testcase (there are now
- warnings, as there should be for any code which won't build [warning-
- free] when !BFD64, and Disp8/Imm8 are no longer used in the warned
- about cases).

-
- gas: invoke md_optimize_expr() also for unary expressions
- Give backends a chance to see these, just as they can see binary ones.
- Most of those which use this hook already cope with NULL being passed

- Adjust the two which don't.
-
- Take the opportunity and also document the hook.

-
- gas: maintain O_constant signedness in more cases
- Unary '~' doesn't really produce an unsigned result. Neither does
- subtraction (unless taking operand values into consideration). And an
- abstract operator applied to two operands which aren't both unsigned
- can't be assumed to yield an unsigned result; exceptions are
- - shifts, where only signedness of the left hand operand matters,
- - comparisons, which - unlike unary '!' - produce signed results (they
- deliver 0 or ~0, as opposed to '!', which yields 0 or 1),
- - logical operators (yielding 0 or 1 and hence treated like unary '!').
-
- While doing this (specifically while extending the all/quad testcase),
- update .quad and .8byte documentation: With 64-bit architectures now
- being common, it is highly inappropriate to state that these directives
- unconditionally require bignums.

- should avoid the truncation. Therefore, like in the other two cases of

- gdb.fortran/lbound-ubound.exp: read expected lbound and ubound from function parameters (PR 30414)
- gdb.fortran/lbound-ubound.exp reads the expected lbound and ubound
- values by reading some output from the inferior. This is racy when
- running on boards where the inferior I/O is on a separate TTY than
- GDB's, such as native-gdbserver.
-
- I sometimes see this behavior:
-
- (gdb) continue
- Continuing.
-
- Breakpoint 2, do_test (lb=..., ub=...) at /home/jenkins/workspace/binutils-gdb_master_linuxbuild/platform/jammy-amd64/target_board/nati
- ve-gdbserver/src/binutils-gdb/gdb/testsuite/gdb.fortran/lbound-ubound.F90:45
- 45 print *, "" ! Test Breakpoint
- (gdb) Remote debugging from host ::1, port 37496
-
- Expected GDB Output:
-
- LBOUND = (-8, -10)
- UBOUND = (-1, -2)
- APB: Run a test here
- APB: Expected lbound '(-8, -10)'
- APB: Expected ubound ''
-
- What happened is that expect read the output from GDB before the output
- from the inferior, triggering this gdb_test_multiple clause:
-
- -re "$gdb_prompt $" {
- set found_prompt true
-
- if {$found_dealloc_breakpoint
- || ($expected_lbound != "" && $expected_ubound != "")} {
- # We're done.
- } else {
- exp_continue
- }
- }
-
- So it set found_prompt, but the gdb_test_multiple kept going because
- found_dealloc_breakpoint is false (this is the flag indicating that the
- test is finished) and we still don't have expected_lbound and
- expected_ubound. Then, expect reads in the inferior I/O, triggering
- this clause:
-
- -re ".*LBOUND = (\[^\r\n\]+)\r\n" {
- set expected_lbound $expect_out(1,string)
- if {!$found_prompt} {
- exp_continue
- }
- }
-
- This sets expected_lbound, but since found_prompt is true, we don't do
- exp_continue, and exit the gdb_test_multiple, without having an
- expected_ubound.
-
- Change the test to read the values from the lb and ub function
- parameters instead. As far as I understand, this still exercises what
- we want to test. These variables contain the return values of the
- lbound and ubound functions as computed by the program. We'll use them
- to check the return values of the lbound and ubound functions as
- computed by GDB.

- gdb/elfread.c: Add plt symbol check for _PROCEDURE_LINKAGE_TABLE_

-
- $ make check-gdb TESTS="gdb.base/gnu-ifunc.exp"

-
- According to IFUNC's working process [1]. first time the IFUNC function
- is called, the dynamic linker will not simply fill the .got.plt entry
- with the actual address of IFUNC symbol, it will call the IFUNC resolver
- function and take the return address, uses it as the sym-bound address
- and puts it in the .got.plt entry. Initial address in .got.plt entry is
- not a real function addresss. Depending on the compiler implementation,
- some different addresses will be filled in. Most architectures will use
- a .plt entry address to fill in the corresponding .got.plt entry.
-
- In gdb, elf_gnu_ifunc_resolve_addr() will be called to return a real
- IFUNC function addresss. First check to see if the real address for
- the IFUNC symbol has been resolved by the following function:
-
- elf_gnu_ifunc_resolve_name (const char *name, CORE_ADDR *addr_p)
- {
- if (elf_gnu_ifunc_resolve_by_cache (name, addr_p))
- return true;
-
- if (elf_gnu_ifunc_resolve_by_got (name, addr_p))
- return true;
-
- return false;
- }
-
- in elf_gnu_ifunc_resolve_by_got(), it gets the contents of the
- .got.plt entry and determines if the contents is the correct address
- by calling elf_gnu_ifunc_record_cache(). Based on the IFUNC working
- principle analysis above, the address filled in the .got.plt entry is
- not the actual target function address initially, it would be a .plt
- entry address corresponding symbol like *@plt. In this case, gdb just
- go back to execute the resolver function and puts the return address
- in the .got.plt entry. After that, gdb can get a real ifun address via
- .got.plt entry.
-
- On LoongArch, initially, each address filled in the .got.plt entries
- is the first .plt entry address. Some architectures such as LoongArch
- define the symbol _PROCEDURE_LINKAGE_TABLE_ at the start of the .plt
- section. This symbol is the first plt entry, so gdb needs to check
- this symbol in elf_gnu_ifunc_record_cache().

- gdb/testsuite: extend special '^' handling to gdb_test_multiple
-
- buildbot notified me of a regression on s390 in the test:
-
- gdb.base/break-main-file-remove-fail.exp
-
- the failure looks like this:
-
- print /d ((int (*) (void *, size_t)) munmap) (16781312, 4096)
- warning: Error removing breakpoint 0
- $2 = 0
- (gdb) FAIL: gdb.base/break-main-file-remove-fail.exp: cmdline: get integer valueof "((int (*) (void *, size_t)) munmap) (16781312, 4096)"
-
- On the mailing list it has been reported that this failure also
- impacts arm, aarch64, and possibly ppc/ppc64 too.
-
- The above commit changed get_integer_valueof so that no output is
- expected between the command and the '$2 = 0' line. In this case the
- 'warning: Error removing breakpoint 0' output is causing the
- get_integer_valueof call to fail.
-
- The reason for this warning is that this test deliberately calls
- munmap on a page of the inferior's code. The test is checking that
- GDB can handle the situation where a s/w breakpoint can't be
- removed (due to the page no longer being readable/writable).
-
- The test that is supposed to trigger the warning is later in the test
- script when we delete a breakpoint.
-
- So why do some targets trigger the warning earlier during the inferior
- call?
-
- The impacted targets use AT_ENTRY_POINT as their strategy for handling
- inferior calls, that is, the trampoline that calls the inferior
- function is placed at the program's entry point, e.g. often the _start
- label.
-
- If this location happens to be on the same page as the page that the
- test script unmaps then, when the inferior function call returns, GDB
- will not be able to remove the temporary breakpoint that is inserted
- to catch the inferior function call returning! As a result we end up
- seeing the warning earlier than expected.
-
- I did wonder if this means I should relax the pattern in
- get_integer_valueof - just accept that there might be additional
- output from GDB which we should ignore.
-
- However, I don't think this the right way to go. With the change in
- a68f7e984420 we are now stricter for GDB emitting additional,
- unexpected, output, and I think that is a good thing.
-
- So, I think, in this case, in order to handle the possible extra
- output, we should implement something like get_integer_valueof
- directly in the gdb.base/break-main-file-remove-fail.exp test script.
- This local version will handle the possible warning output.
-
- After this the test should pass again on the impacted targets.

- gdb/python: extend the Python Disassembler API to allow for styling
- This commit extends the Python Disassembler API to allow for styling
- of the instructions.
-
- Before this commit the Python Disassembler API allowed the user to do
- two things:
-
- - They could intercept instruction disassembly requests and return a
- string of their choosing, this string then became the disassembled
- instruction, or
-
- - They could call builtin_disassemble, which would call back into
- libopcode to perform the disassembly. As libopcode printed the
- instruction GDB would collect these print requests and build a
- string. This string was then returned from the builtin_disassemble
- call, and the user could modify or extend this string as needed.
-
- Neither of these approaches allowed for, or preserved, disassembler
- styling, which is now available within libopcodes for many of the more
- popular architectures GDB supports.
-
- This commit aims to fill this gap. After this commit a user will be
- able to do the following things:
-
- - Implement a custom instruction disassembler entirely in Python
- without calling back into libopcodes, the custom disassembler will
- be able to return styling information such that GDB will display
- the instruction fully styled. All of GDB's existing style
- settings will affect how instructions coming from the Python
- disassembler are displayed in the expected manner.
-
- - Call builtin_disassemble and receive a result that represents how
- libopcode would like the instruction styled. The user can then
- adjust or extend the disassembled instruction before returning the
- result to GDB. Again, the instruction will be styled as expected.
-
- To achieve this I will add two new classes to GDB,
- DisassemblerTextPart and DisassemblerAddressPart.
-
- Within builtin_disassemble, instead of capturing the print calls from
- libopcodes and building a single string, we will now create either a
- text part or address part and store these parts in a vector.
-
- The DisassemblerTextPart will capture a small piece of text along with
- the associated style that should be used to display the text. This
- corresponds to the disassembler calling
- disassemble_info::fprintf_styled_func, or for disassemblers that don't
- support styling disassemble_info::fprintf_func.
-
- The DisassemblerAddressPart is used when libopcodes requests that an
- address be printed, and takes care of printing the address and
- associated symbol, this corresponds to the disassembler calling
- disassemble_info::print_address_func.
-
- These parts are then placed within the DisassemblerResult when
- builtin_disassemble returns.
-
- Alternatively, the user can directly create parts by calling two new
- methods on the DisassembleInfo class: DisassembleInfo.text_part and
- DisassembleInfo.address_part.
-
- Having created these parts the user can then pass these parts when
- initializing a new DisassemblerResult object.
-
- Finally, when we return from Python to gdbpy_print_insn, one way or
- another, the result being returned will have a list of parts. Back in
- GDB's C++ code we walk the list of parts and call back into GDB's core
- to display the disassembled instruction with the correct styling.
-
- The new API lives in parallel with the old API. Any existing code
- that creates a DisassemblerResult using a single string immediately
- creates a single DisassemblerTextPart containing the entire
- instruction and gives this part the default text style. This is also
- what happens if the user calls builtin_disassemble for an architecture
- that doesn't (yet) support libopcode styling.
-
- This matches up with what happens when the Python API is not involved,
- an architecture without disassembler styling support uses the old
- libopcodes printing API (the API that doesn't pass style info), and
- GDB just prints everything using the default text style.
-
- The reason that parts are created by calling methods on
- DisassembleInfo, rather than calling the class constructor directly,
- is DisassemblerAddressPart. Ideally this part would only hold the
- address which the part represents, but in order to support backwards
- compatibility we need to be able to convert the
- DisassemblerAddressPart into a string. To do that we need to call
- GDB's internal print_address function, and to do that we need an
- gdbarch.
-
- What this means is that the DisassemblerAddressPart needs to take a
- gdb.Architecture object at creation time. The only valid place a user
- can pull this from is from the DisassembleInfo object, so having the
- DisassembleInfo act as a factory ensures that the correct gdbarch is
- passed over each time. I implemented both solutions (the one
- presented here, and an alternative where parts could be constructed
- directly), and this felt like the cleanest solution.

- gdb/python: rework how the disassembler API reads the result object
- This commit is a refactor ahead of the next change which will make
- disassembler styling available through the Python API.
-
- Unfortunately, in order to make the styling support available, I think
- the easiest solution is to make a very small change to the existing
- API.
-
- The current API relies on returning a DisassemblerResult object to
- represent each disassembled instruction. Currently GDB allows the
- DisassemblerResult class to be sub-classed, which could mean that a
- user tries to override the various attributes that exist on the
- DisassemblerResult object.
-
- This commit removes this ability, effectively making the
- DisassemblerResult class final.
-
- Though this is a change to the existing API, I'm hoping this isn't
- going to cause too many issues:
-
- - The Python disassembler API was only added in the previous release
- of GDB, so I don't expect it to be widely used yet, and
-
- - It's not clear to me why a user would need to sub-class the
- DisassemblerResult type, I allowed it in the original patch
- because at the time I couldn't see any reason to NOT allow it.
-
- Having prevented sub-classing I can now rework the tail end of the
- gdbpy_print_insn function; instead of pulling the results out of the
- DisassemblerResult object by calling back into Python, I now cast the
- Python object back to its C++ type (disasm_result_object), and access
- the fields directly from there. In later commits I will be reworking
- the disasm_result_object type in order to hold information about the
- styled disassembler output.
-
- The tests that dealt with sub-classing DisassemblerResult have been
- removed, and a new test that confirms that DisassemblerResult can't be
- sub-classed has been added.

- Fix regression due to Pragma Import series
- A co-worker here at AdaCore discovered that the Pragma Import series

- Multiple matches for pp
- [0] cancel

-
- This worked before the series, and is strange anyway, because the
- matches refer to the same function.
-

-
-2023-05-12 Tom Tromey <tromey@adacore.com>
-
- Use bool and early loop exit in remove_extra_symbols

-
- Use reference parameter in remove_extra_symbols
- Changing ada-lang.c:remove_extra_symbols to take a reference parameter
- makes the code a bit easier to read, by replacing "(*syms)" with plain
- "syms".
-
- Handle Ada Pragma Import and Pragma Export
- Ada can import C APIs and also export Ada constructs to C via Pragma
- Import and Pragma Export. This patch adds support for these to gdb,
- by arranging to either defer some aspects of a symbol to the
- underlying C symbol (for Import) or by introducing a second symbol
- (for Export). A somewhat tricky approach is needed, both because gdb
- doesn't generally handle symbol aliasing, and because Ada treats
- symbol names in an unusual way (as compared to the rest of gdb).
-
- Introduce symbol_block_ops::get_block_value
- This adds a new callback to symbol_block_ops. This callback lets a
- LOC_BLOCK symbol implement its own function to find the underlying
- block.
-
- Define symbol::value_block separately
- This moves the definition of symbol::value_block outside of the class.
- A subsequent patch will change this method to use SYMBOL_BLOCK_OPS,
- and it seemed simplest to move this method out-of-line, and cleaner to

- gdb/testsuite: extend special '^' handling to gdb_test_multiple
- The commit:
-
- commit 08ec06d6440745ef9204d39197aa1e732df41056
- Date: Wed Mar 29 10:41:07 2023 +0100
-
- gdb/testsuite: special case '^' in gdb_test pattern
-
- Added some special handling of '^' to gdb_test -- a leading '^' will
- cause the command regexp to automatically be included in the expected
- output pattern.
-
- It was pointed out that the '-wrap' flag of gdb_test_multiple is
- supposed to work in the same way as gdb_test, and that the recent
- changes for '^' had not been replicated for gdb_test_multiple. This
- patch addresses this issue.
-
- So, after this commit, the following two constructs should have the
- same meaning:
-
- gdb_test "command" "^output" "test name"
-
- gdb_test_multiple "command" "test name" {
- -re -wrap "^output" {
- pass $gdb_test_name
- }
- }
-
- In both cases the '^' will case gdb.exp to inject a regexp that
- matches 'command' after the '^' and before the 'output', this is in
- addition to adding the $gdb_prompt pattern after 'output' in the
- normal way.
-
- The special '^' handling is only applied when '-wrap' is used, as this
- is the only mode that aims to mimic gdb_test.
-
- While working on this patch I realised that I could actually improve
- the logic for the special '^' handling in the case where the expected
- output pattern is empty. I replicated these updates for both gdb_test
- and gdb_test_multiple in order to keep these two paths in sync.
-
- There were a small number of tests that needed adjustment after this
- change, mostly just removing command regexps that are now added
- automatically, but the gdb.base/settings.exp case was a little weird
- as it turns out trying to match a single blank line is probably harder
- now than it used to be -- still, I suspect this is a pretty rare case,
- so I think the benefits (improved anchoring) outweigh this small
- downside (IMHO).

- gdb: fix error message for $_gdb_maint_setting
- I spotted this behaviour:
-
- (gdb) p $_gdb_maint_setting("xxx")
- First argument of $_gdb_maint_setting must be a valid setting of the 'show' command.
-
- Notice that GDB claims I need to use a setting from the 'show'
- command, which isn't correct for $_gdb_maint_setting, in this case I
- need to use a setting from 'maintenance show'.

- This same issue is present for $_gdb_maint_setting_str.

- [gdb/testsuite] Fix gdb.dwarf2/opt-out-not-implptr.exp for -m32
- When running test-case gdb.dwarf2/opt-out-not-implptr.exp with target board
- unix/-m32 we have:
- ...
- (gdb) print noptr^M
- $1 = {0, <optimized out>, <optimized out>, <optimized out>}^M
- (gdb) FAIL: gdb.dwarf2/opt-out-not-implptr.exp: print noptr
- ...
-
- The problem happens when evaluating this dwarf expression:
- ...
- <45> DW_AT_location : 13 byte block: 10 86 ea d7 d0 96 8e cf 92 5c 9f 93 8 \
- (DW_OP_constu: 6639779683436459270; DW_OP_stack_value; DW_OP_piece: 8)
- ...
-
- The DW_OP_constu pushes a value with "generic type" on to the DWARF stack, and
- the "generic type" has the size of an address on the target machine, which for
- target board unix/-m32 is 4 bytes. Consequently, the constant is abbreviated.
-
- Next, the DW_OP_piece declares that the resulting 4-byte value is 8 bytes
- large, and we hit this clause in rw_pieced_value:
- ...
- /* Use zeroes if piece reaches beyond stack value. */
- if (p->offset + p->size > stack_value_size_bits)
- break;
- ...
- and consequently get a zero.
-
- We could just add require is_target_64 to the test-case, but instead, add a
- 32-bit case and require is_target_64 just for the 64-bit case.
-
- Tested on x86_64-linux.

- [gdb/testsuite] Make is_64_target more robust
- I ran test-case gdb.dwarf2/opt-out-not-implptr.exp with make-check-all.sh, and
- with target board dwarf64 ran into:
- ...
- FAIL: gdb.dwarf2/opt-out-not-implptr.exp: print noptr
- ...
- due to is_target_64 failing because of:
- ...
- builtin_spawn -ignore SIGHUP gcc -fno-stack-protector \
- -fdiagnostics-color=never -w -c -gdwarf64 -g -o is_64_target.o \
- is_64_target.c^M
- gcc: error: '-gdwarf64' is ambiguous; use '-gdwarf-64' for DWARF version or \
- '-gdwarf -g64' for debug level^M
- compiler exited with status 1
- ...
-
- The FAIL is the same FAIL I run into with target board unix/-m32: is_target_64
- fails for both cases.
-
- The reason that is_target_64 is failing for target board dwarf64, is because
- of using system compiler 7.5.0 which doesn't support -gdwarf64.
-
- Fix this by making is_target_64 use nodebug instead of debug for compilation.

- [gdb/cli] Fix wrapping for TERM=ansi
- I. Auto-detected width (xterm vs. ansi)
-
- Say we have a terminal with a width of 40 chars:
- ...
- $ echo $COLUMNS
- 40
- ...
-
- With TERM=xterm, we report a width of 40 chars:
- ...
- $ TERM=xterm gdb
- (gdb) show width
- Number of characters gdb thinks are in a line is 40.
- ...
-
- And with TERM=ansi, a width of 39 chars:
- ...
- $ TERM=ansi gdb
- (gdb) show width
- Number of characters gdb thinks are in a line is 39.
- ...
-
- Gdb uses readline to auto-detect screen size, and readline decides in the
- TERM=ansi case that the terminal does not have reliable auto-wrap, and
- consequently decides to hide the last terminal column from the readline user
- (in other words GDB), hence we get 39 instead of 40.
-
- II. Types of wrapping
-
- Looking a bit more in detail inside gdb, it seems there are two types of
- wrapping:
- - readline wrapping (in other words, prompt edit wrapping), and
- - gdb output wrapping (can be observed by issuing "info sources").
- This type of wrapping attempts to wrap some of the gdb output earlier
- than the indicated width, to not break lines in inconvenient places.
-
- III. Readline wrapping, auto-detected screen size
-
- Let's investigate readline wrapping with the auto-detected screen widths.
-
- First, let's try with xterm:
- ...
- $ TERM=xterm gdb
- (gdb) 7890123456789012345678901234567890
- 123
- ...
- That looks as expected, wrapping occurs after 40 chars.
-
- Now, let's try with ansi:
- ...
- $ TERM=ansi gdb
- (gdb) 78901234567890123456789012345678
- 90123
- ...
- It looks like wrapping occurred after 38, while readline should be capable of
- wrapping after 39 chars.
-
- This is caused by readline hiding the last column, twice.
-
- In more detail:
- - readline detects the screen width: 40,
- - readline hides the last column, setting the readline screen width to 39,
- - readline reports 39 to gdb as screen width,
- - gdb sets its width setting to 39,
- - gdb sets readline screen width to 39,
- - readline hides the last column, again, setting the readline screen width to
- 38.
-
- This is reported as PR cli/30346.
-
- IV. gdb output wrapping, auto-detected screen size
-
- Say we set the terminal width to 56. With TERM=xterm, we have:
- ...
- /home/abuild/rpmbuild/BUILD/glibc-2.31/csu/elf-init.c,
- /data/vries/hello.c,
- ...
- but with TERM=ansi:
- ...
- /home/abuild/rpmbuild/BUILD/glibc-2.31/csu/elf-init.c, /
- data/vries/hello.c,
- ...
-
- So what happened here? With TERM=ansi, the width setting is auto-detected to
- 55, and gdb assumes the terminal inserts a line break there, which it doesn't
- because the terminal width is 56.
-
- This is reported as PR cli/30411.
-
- V. Fix PRs
-
- Fix both mentioned PRs by taking into account the hidden column when readline
- reports the screen width in init_page_info, and updating chars_per_line
- accordingly.
-
- Note that now we report the same width for both TERM=xterm and TERM=ansi,
- which is much clearer.
-
- The point where readline respectively expects or ensures wrapping is still
- indicated by "maint info screen", for xterm:
- ...
- Number of characters readline reports are in a line is 40.
- ...
- and ansi:
- ...
- Number of characters readline reports are in a line is 39.
- ...
-
- VI. Testing
-
- PR cli/30346 is covered by existing regression tests gdb.base/wrap-line.exp
- and gdb.tui/wrap-line.exp, so remove the KFAILs there.
-
- I didn't manage to come up with a regression test for PR cli/30411. Perhaps
- that would be easier if we had a maintenance command that echoes its arguments
- while applying gdb output wrapping.
-
- Tested on x86_64-linux.

- gas: equates of registers
- There are two problems: symbol_equated_p() doesn't recognize equates of
- registers, and S_CAN_BE_REDEFINED() goes by section rather than by
- expression type. Both together undermine .eqv and .equiv clearly meaning
- to guard the involved symbols against re-definition (both ways).
-
- To compensate pseudo_set() now using O_symbol and S_CAN_BE_REDEFINED()
- now checking for O_register,
- - for targets creating register symbols through symbol_{new,create}() ->
- symbol_init() -> S_SET_VALUE() (alpha, arc, dlx, ia64, m68k, mips,
- mmix, tic4x, tic54x, plus anything using cgen or itbl-ops), have
- symbol_init() set their expressions to O_register,
- - x86'es parse_register() also can't go by section anymore when
- trying to "look through" equates; probably symbol_equated_p() should
- have been used there from the beginning, if only that had worked for
- equates of registers,
- - various targets need to "look through" equates when parsing insn
- operands (which also helps transitive forward equates); perhaps even
- more ought to, but many don't look to consider the possibility of
- register equates in the first place.
-
- This was uncovered by code reported in PR gas/30274 (duplicating
- PR gas/30272), except that there .eqv was used when really .equ was
- meant. Therefore that bug report is addressed here only in so far as
- gas wouldn't crash anymore; the code there still won't assemble
- successfully, just that now the issues there are properly diagnosed.

- Do not print <synthetic pointer> when piece is optimized out
- A user reported a bug where printing a certain array of integer types

-
- (gdb) p l_126
- $1 = {6639779683436459270, <synthetic pointer>, <synthetic pointer>, <synthetic pointer>}
-
- I tracked this down to some issues in the DWARF expression code.
- First, check_pieced_synthetic_pointer did not account for the
- situation where a location expression does not describe all the bits
- of a value -- in this case it returned true, meaning there is a
- synthetic pointer, but in fact these bits are optimized out. (It

- Disable out-of-scope watchpoints
- Currently, when a local software watchpoint goes out of scope, GDB sets
- the watchpoint's disposition to `delete at next stop' and then normal
- stops (i.e., stop and wait for the next GDB command). When GDB normal
- stops, it automatically deletes the breakpoints with their disposition
- set to `delete at next stop'.
-
- Suppose a Python script decides not to normal stop when a local
- software watchpoint goes out of scope, the watchpoint will not be
- automatically deleted even when its disposition is set to
- `delete at next stop'.
-
- Since GDB single-steps the program and tests the watched expression
- after each instruction, not deleting the watchpoint causes the
- watchpoint to be hit many more times than it should, as reported in
- PR python/29603.
-
- This was happening because the watchpoint is not deleted or disabled
- when going out of scope.
-
- This commit fixes this issue by disabling the watchpoint when going out
- of scope. It also adds a test to ensure this feature isn't regressed in
- the future.
-
- Calling `breakpoint_auto_delete' on all kinds of stops (in
- `fetch_inferior_event') seem to solve this issue, but is in fact
- inappropriate, since `breakpoint_auto_delete' goes over all breakpoints
- instead of just going through the bpstat chain (which only contains the
- breakpoints that were hit right now).

- Add LDPT_REGISTER_CLAIM_FILE_HOOK_V2 linker plugin hook [GCC PR109128]
- This is one part of the fix for GCC PR109128, along with a
- corresponding GCC change. Without this patch, what happens in the
- linker, when an unused object in a .a file has offload data, is that
- elf_link_is_defined_archive_symbol calls bfd_link_plugin_object_p,
- which ends up calling the plugin's claim_file_handler, which then
- records the object as one with offload data. That is, the linker never
- decides to use the object in the first place, but use of this _p
- interface (called as part of trying to decide whether to use the
- object) results in the plugin deciding to use its offload data (and a
- consequent mismatch in the offload data present at runtime).
-
- The new hook allows the linker plugin to distinguish calls to
- claim_file_handler that know the object is being used by the linker
- (from ldmain.c:add_archive_element), from calls that don't know it's
- being used by the linker (from elf_link_is_defined_archive_symbol); in
- the latter case, the plugin should avoid recording the object as one
- with offload data.

- gdb/rust: fix crash for expression debug with strings
- While working on another patch I did this:
-
- (gdb) set debug expression 1
- (gdb) set language rust
- (gdb) p "foo"
- Operation: OP_AGGREGATE
- Type: &str
-
- Fatal signal: Segmentation fault
- ... etc ...
-
- The problem is that the second field of the rust_aggregate_operation
- is created as a nullptr, this can be seen in rust-parse.c. in the
- function rust_parser::parse_string().
-
- However, in expop.h, in the function dump_for_expression, we make the
- assumption that the expressions will never be nullptr.
-
- I did consider moving the nullptr handling into a new function
- rust_aggregate_operation::dump, however, as the expression debug
- dumping code is not exercised as much as it might be, I would rather
- that this code be hardened and able to handle a nullptr without
- crashing, so I propose that we add nullptr handling into the general
- dump_for_expression function. The behaviour is now:
-
- (gdb) set debug expression 1
- (gdb) set language rust
- (gdb) p "foo"
- Operation: OP_AGGREGATE
- Type: &str

- String: data_ptr

- [gdb/tui] Fix tui compact-source
- Consider a hello.c, with less than 10 lines:
- ...
- $ wc -l hello.c
- 8 hello.c
- ...
- and compiled with -g into an a.out.
-
- With compact-source off:
- ...
- $ gdb -q a.out \
- -ex "set tui border-kind ascii" \
- -ex "maint set tui-left-margin-verbose on" \
- -ex "set tui compact-source off" \
- -ex "tui enable"
- ...
- we get:
- ...
- +-./data/hello.c-----------------------+
- |___000005_{ |
- |___000006_ printf ("hello\n"); |
- |___000007_ return 0; |
- |___000008_} |
- |___000009_ |
- |___000010_ |
- |___000011_ |
- ...
- but with compact-source on:
- ...
- +-./data/hello.c-----------------------+
- |___5{ |
- |___6 printf ("hello\n"); |
- |___7 return 0; |
- |___8} |
- |___9 |
- |___1 |
- |___1 |
- ...
-
- There are a couple of problems with compact-source.
-
- First of all the documentation mentions:
- ...
- The default display uses more space for line numbers and starts the
- source text at the next tab stop; the compact display uses only as
- much space as is needed for the line numbers in the current file, and
- only a single space to separate the line numbers from the source.
- ...
-
- The bit about the default display and the next tab stop looks incorrect. The
- source doesn't start at a tab stop, instead it uses a single space to separate
- the line numbers from the source.
-
- Then the documentation mentions that there's single space in the compact
- display, but evidently that's missing.
-
- Then there's the fact that the line numbers "10" and "11" are both abbreviated
- to "1" in the compact case.
-
- The abbreviation is due to allocating space for <lines in source>, which is
- 8 for this example, and takes a single digit. The line numbers though
- continue past the end of the file, so fix this by allocating space for
- max (<lines in source>, <last line in window>), which in this example takes 2
- digits.
-
- The missing space is due to some confusion about what the "1" here in
- tui_source_window::set_contents represent:
- ...
- double l = log10 ((double) offsets->size ());
- m_digits = 1 + (int) l;
- ...
-
- It could be the trailing space that's mentioned in tui-source.h:
- ...
- /* How many digits to use when formatting the line number. This
- includes the trailing space. */
- int m_digits;
- ...
-
- Then again, it could be part of the calculation for the number of digits
- needed for printing. With this minimal example:
- ...
- int main () {
- for (int i = 8; i <= 11; ++i) {
- double l = log10 ((double) i);
- printf ("%d %d\n", i, (int)l);
- }
- return 0;
- }
- ...
- we get:
- ...
- $ ./a.out
- 8 0
- 9 0
- 10 1
- 11 1
- ...
- which shows that the number of digits needed for printing i is
- "1 + (int)log10 ((double) i)".
-
- Fix this by introducing named variables needed_digits and trailing_space, each
- adding 1.
-
- With the fixes, we get for compact-source on:
- ...
- +-./data/hello.c-----------------------+
- |___05_{ |
- |___06_ printf ("hello\n"); |
- |___07_ return 0; |
- |___08_} |
- |___09_ |
- |___10_ |
- |___11_ |
- |...
-
- Also fix the documentation and help text to actually match effect of
- compact-source.
-
- Tested on x86_64-linux.

- gdb: fix use-after-free in check_longjmp_breakpoint_for_call_dummy
- Commit 7a8de0c33019 ("Remove ALL_BREAKPOINTS_SAFE") introduced a
- use-after-free in the breakpoints iterations (see below for full ASan
- report). This makes gdb.base/stale-infcall.exp fail when GDB is build
- with ASan.
-
- check_longjmp_breakpoint_for_call_dummy iterates on all breakpoints,
- possibly deleting the current breakpoint as well as related breakpoints.
- The problem arises when a breakpoint in the B->related_breakpoint chain
- is also B->next. In that case, deleting that related breakpoint frees
- the breakpoint that all_breakpoints_safe has saved.
-
- The old code worked around that by manually changing B_TMP, which was
- the next breakpoint saved by the "safe iterator":
-
- while (b->related_breakpoint != b)
- {
- if (b_tmp == b->related_breakpoint)
- b_tmp = b->related_breakpoint->next;
- delete_breakpoint (b->related_breakpoint);
- }
-
- (Note that this seemed to assume that b->related_breakpoint->next was
- the same as b->next->next, not sure this is guaranteed.)
-
- The new code kept the B_TMP variable, but it's not useful in that
- context. We can't go change the next breakpoint as saved by the safe
- iterator, like we did before. I suggest fixing that by saving the
- breakpoints to delete in a map and deleting them all at the end.
-
- Here's the full ASan report:
-
- (gdb) PASS: gdb.base/stale-infcall.exp: continue to breakpoint: break-run1

- gdb/python: add mechanism to manage Python initialization functions
- Currently, when we add a new python sub-system to GDB,
- e.g. py-inferior.c, we end up having to create a new function like
- gdbpy_initialize_inferior, which then has to be called from the
- function do_start_initialization in python.c.
-
- In some cases (py-micmd.c and py-tui.c), we have two functions
- gdbpy_initialize_*, and gdbpy_finalize_*, with the second being called
- from finalize_python which is also in python.c.
-
- This commit proposes a mechanism to manage these initialization and
- finalization calls, this means that adding a new Python subsystem will
- no longer require changes to python.c or python-internal.h, instead,
- the initialization and finalization functions will be registered
- directly from the sub-system file, e.g. py-inferior.c, or py-micmd.c.
-
- The initialization and finalization functions are managed through a
- new class gdbpy_initialize_file in python-internal.h. This class
- contains a single global vector of all the initialization and
- finalization functions.
-
- In each Python sub-system we create a new gdbpy_initialize_file
- object, the object constructor takes care of registering the two
- callback functions.
-
- Now from python.c we can call static functions on the
- gdbpy_initialize_file class which take care of walking the callback
- list and invoking each callback in turn.
-
- To slightly simplify the Python sub-system files I added a new macro
- GDBPY_INITIALIZE_FILE, which hides the need to create an object. We
- can now just do this:
-
- GDBPY_INITIALIZE_FILE (gdbpy_initialize_registers);
-
- One possible problem with this change is that there is now no
- guaranteed ordering of how the various sub-systems are initialized (or
- finalized). To try and avoid dependencies creeping in I have added a
- use of the environment variable GDB_REVERSE_INIT_FUNCTIONS, this is
- the same environment variable used in the generated init.c file.
-
- Just like with init.c, when this environment variable is set we
- reverse the list of Python initialization (and finalization)
- functions. As there is already a test that starts GDB with the
- environment variable set then this should offer some level of
- protection against dependencies creeping in - though for full
- protection I guess we'd need to run all gdb.python/*.exp tests with
- the variable set.
-
- I have tested this patch with the environment variable set, and saw no
- regressions, so I think we are fine right now.
-
- One other change of note was for gdbpy_initialize_gdb_readline, this
- function previously returned void. In order to make this function
- have the correct signature I've updated its return type to int, and we
- now return 0 to indicate success.
-
- All of the other initialize (and finalize) functions have been made
- static within their respective sub-system files.
-
- There should be no user visible changes after this commit.

- gdb/testsuite: more newline pattern cleanup
- After this commit:
-
- commit e2f620135d92f7cd670af4e524fffec7ac307666
- Date: Thu Mar 30 13:26:25 2023 +0100

- gdb/testsuite: change newline patterns used in gdb_test
-
- It was pointed out in PR gdb/30403 that the same patterns can be found
- in other lib/gdb.exp procs and that it would probably be a good idea
- if these procs remained in sync with gdb_test. Actually, the bug
- specifically calls out gdb_test_multiple when using with '-wrap', but
- I found a couple of other locations in gdb_continue_to_breakpoint,
- gdb_test_multiline, get_valueof, and get_local_valueof.
-
- In all these locations one or both of the following issues are
- addressed:
-
- 1. A leading pattern of '[\r\n]*' is pointless. If there is a
- newline it will be matched, but if there is not then the testsuite
- doesn't care. Also, as expect is happy to skip non-matched output
- at the start of a pattern, if there is a newline expect is happy to
- skip over it before matching the rest. As such, this leading
- pattern is removed.
-
- 2. Using '\[\r\n\]*$gdb_prompt' means that we will swallow
- unexpected blank lines at the end of a command's output, but also,
- if the pattern from the test script ends with a '\r', '\n', or '.'
- then these will partially match the trailing newline, with the
- remainder of the newline matched by the pattern from gdb.exp. This
- split matching doesn't add any value, it's just something that has
- appeared as a consequence of how gdb.exp was originally written. In
- this case the '\[\r\n\]*' is replaced with '\r\n'.
-
- I've rerun the testsuite and fixed the regressions that I saw, these
- were places where GDB emits a blank line at the end of the command
- output, which we now need to explicitly match in the test script, this
- was for:
-
- gdb.dwarf2/dw2-out-of-range-end-of-seq.exp
- gdb.guile/guile.exp
- gdb.python/python.exp
-
- Or a location where the test script was matching part of the newline
- sequence, while gdb.exp was previously matching the remainder of the
- newline sequence. Now we rely on gdb.exp to match the complete
- newline sequence, this was for:
-
- gdb.base/commands.exp

- (which is generated in build-id.c) didn't actually include the

-
- This commit extends the test pattern to check for the full warning

- Simplify decode_locdesc
- While looking into another bug, I noticed that the DWARF cooked
- indexer picks up an address for this symbol:
-
- <1><82>: Abbrev Number: 2 (DW_TAG_variable)
- <83> DW_AT_specification: <0x9f>
- <87> DW_AT_location : 10 byte block: e 0 0 0 0 0 0 0 0 e0 (DW_OP_const8u: 0 0; DW_OP_GNU_push_tls_address or DW_OP_HP_unknown)
- <92> DW_AT_linkage_name: (indirect string, offset: 0x156): _ZN9container8tlsvar_0E
-
- This happens because decode_locdesc allows the use of
- DW_OP_GNU_push_tls_address.
-
- This didn't make sense to me. I looked into it a bit more, and I
- think decode_locdesc is used in three ways:
-
- 1. Find a constant address of a symbol that happens to be encoded as a
- location expression.
-
- 2. Find the offset of a function in a virtual table. (This one should
- probably be replaced by code to just evaluate the expression in
- gnu-v3-abi.c -- but there's no point yet because no compiler
- actually seems to emit correct DWARF here, see the bug linked in
- the patch.)
-
- 3. Find the offset of a field, if the offset is a constant.
-
- None of these require TLS.
-
- This patch simplifies decode_locdesc by removing any opcodes that
- don't fit into the above. It also changes the API a little, to make
- it less difficult to use.

- Don't treat references to compound values as "simple".
- SUMMARY
-
- The '--simple-values' argument to '-stack-list-arguments' and similar
- GDB/MI commands does not take reference types into account, so that
- references to arbitrarily large structures are considered "simple" and
- printed. This means that the '--simple-values' argument cannot be used
- by IDEs when tracing the stack due to the time taken to print large
- structures passed by reference.
-
- DETAILS
-
- Various GDB/MI commands ('-stack-list-arguments', '-stack-list-locals',
- '-stack-list-variables' and so on) take a PRINT-VALUES argument which
- may be '--no-values' (0), '--all-values' (1) or '--simple-values' (2).
- In the '--simple-values' case, the command is supposed to print the
- name, type, and value of variables with simple types, and print only the
- name and type of variables with compound types.
-
- The '--simple-values' argument ought to be suitable for IDEs that need
- to update their user interface with the program's call stack every time
- the program stops. However, it does not take C++ reference types into
- account, and this makes the argument unsuitable for this purpose.
-
- For example, consider the following C++ program:
-
- struct s {
- int v[10];
- };
-
- int
- sum(const struct s &s)
- {
- int total = 0;
- for (int i = 0; i < 10; ++i) total += s.v[i];
- return total;
- }
-
- int
- main(void)
- {
- struct s s = { { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 } };
- return sum(s);
- }
-
- If we start GDB in MI mode and continue to 'sum', the behaviour of
- '-stack-list-arguments' is as follows:
-
- (gdb)
- -stack-list-arguments --simple-values
- ^done,stack-args=[frame={level="0",args=[{name="s",type="const s &",value="@0x7fffffffe310: {v = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}}"}]},frame={level="1",args=[]}]
-
- Note that the value of the argument 's' was printed, even though 's' is
- a reference to a structure, which is not a simple value.
-
- See https://github.com/microsoft/MIEngine/pull/673 for a case where this
- behaviour caused Microsoft to avoid the use of '--simple-values' in
- their MIEngine debug adapter, because it caused Visual Studio Code to
- take too long to refresh the call stack in the user interface.
-
- SOLUTIONS
-
- There are two ways we could fix this problem, depending on whether we
- consider the current behaviour to be a bug.
-
- 1. If the current behaviour is a bug, then we can update the behaviour
- of '--simple-values' so that it takes reference types into account:
- that is, a value is simple if it is neither an array, struct, or
- union, nor a reference to an array, struct or union.
-
- In this case we must add a feature to the '-list-features' command so
- that IDEs can detect that it is safe to use the '--simple-values'
- argument when refreshing the call stack.
-
- 2. If the current behaviour is not a bug, then we can add a new option
- for the PRINT-VALUES argument, for example, '--scalar-values' (3),
- that would be suitable for use by IDEs.
-
- In this case we must add a feature to the '-list-features' command
- so that IDEs can detect that the '--scalar-values' argument is
- available for use when refreshing the call stack.
-
- PATCH
-
- This patch implements solution (1) as I think the current behaviour of
- not printing structures, but printing references to structures, is
- contrary to reasonable expectation.

- [gdb/build] Fix frame_list position in frame.c
- In commit 995a34b1772 ("Guard against frame.c destructors running before
- frame-info.c's") the following problem was addressed.
-
- The frame_info_ptr destructor:
- ...
- ~frame_info_ptr ()
- {
- frame_list.erase (frame_list.iterator_to (*this));
- }
- ...
- uses frame_list, which is a static member of class frame_info_ptr,
- instantiated in frame-info.c:
- ...
- intrusive_list<frame_info_ptr> frame_info_ptr::frame_list;
- ...
-
- Then there's a static frame_info_pointer variable named selected_frame in
- frame.c:
- ...
- static frame_info_ptr selected_frame;
- ...
-
- Because the destructor of selected_frame uses frame_list, its destructor needs
- to be called before the destructor of frame_list.
-
- But because they're in different compilation units, the initialization order and
- consequently destruction order is not guarantueed.
-
- The commit fixed this by handling the case that the destructor of frame_list
- is called first, adding a check on is_linked ():
- ...
- ~frame_info_ptr ()
- {
- - frame_list.erase (frame_list.iterator_to (*this));
- + /* If this node has static storage, it may be deleted after
- + frame_list. Attempting to erase ourselves would then trigger
- + internal errors, so make sure we are still linked first. */
- + if (is_linked ())
- + frame_list.erase (frame_list.iterator_to (*this));
- }
- ...
-
- However, since then frame_list has been moved into frame.c, and
- initialization/destruction order is guarantueed inside a compilation unit.
-
- Revert aforementioned commit, and fix the destruction order problem by moving
- frame_list before selected_frame.
-
- Reverting the commit is another way of fixing the already fixed
- Wdangling-pointer warning reported in PR build/30413, in a different way than
- commit 9b0ccb1ebae ("Pass const frame_info_ptr reference for
- skip_[language_]trampoline").

- [gdb/tui] Fix TUI resizing for TERM=ansi
- With TERM=ansi, when resizing a TUI window from LINES/COLUMNS 31/118
- (maximized) to 20/78 (de-maximized), I get a garbled screen (that ^L doesn't
- fix) and a message:
- ...
- @@ resize done 0, size = 77x20
- ...
- with the resulting width being 77 instead of the expected 78.
-
- [ The discrepancy also manifests in CLI, filed as PR30346. ]
-
- The discrepancy comes from tui_resize_all, where we ask readline for the
- screen size:
- ...
- rl_get_screen_size (&screenheight, &screenwidth);
- ...
-
- As it happens, when TERM is set to ansi, readline decides that the terminal
- cannot auto-wrap lines, and reserves one column to deal with that, and as a
- result reports back one less than the actual screen width:
- ...
- $ echo $COLUMNS
- 78
- $ TERM=xterm gdb -ex "show width" -ex q
- Number of characters gdb thinks are in a line is 78.
- $ TERM=ansi gdb -ex "show width" -ex q
- Number of characters gdb thinks are in a line is 77.
- ...
-
- In tui_resize_all, we need the actual screen width, and using a screenwidth of
- one less than the actual value garbles the screen.
-
- This is currently not causing trouble in testing because we have a workaround
- in place in proc Term::resize. If we disable the workaround:
- ...
- - stty columns [expr {$_cols + 1}] < $::gdb_tty_name
- + stty columns $_cols < $::gdb_tty_name
- ...
- and dump the screen we get the same type of screen garbling:
- ...
- 0 +---------------------------------------+|
- 1 ||
- 2 ||
- 3 ||
- ...
-
- Another way to reproduce the problem is using command "maint info screen".
- After starting gdb with TERM=ansi, entering TUI, and issuing the command, we
- get:
- ...
- Number of characters curses thinks are in a line is 78.
- ...
- and after maximizing and demaximizing the window we get:
- ...
- Number of characters curses thinks are in a line is 77.
- ...
- If we use TERM=xterm, we do get the expected 78.
-
- Fix this by:
- - detecting when readline will report back less than the actual screen width,
- - accordingly setting a new variable readline_hidden_cols,
- - using readline_hidden_cols in tui_resize_all to fix the resize problem, and
- - removing the workaround in Term::resize.
-
- The test-case gdb.tui/empty.exp serves as regression test.
-
- I've applied the same fix in tui_async_resize_screen, the new test-case
- gdb.tui/resize-2.exp serves as a regression test for that change. Without

- Latest libc++[1] causes transitive include to <locale> when
- <mutex> or <thread> header is included. This causes
- gdb to not build[2] since <locale> defines isupper/islower etc.
- functions that are explicitly macroed-out in safe-ctype.h to
- prevent their use.
- Use the suggestion from libc++ to include <locale> internally when
- building in C++ mode to avoid build errors.
- Use safe-gdb-ctype.h as the include instead of "safe-ctype.h"
- to keep this isolated to gdb since rest of binutils
- does not seem to use much C++.

- Aborted (core dumped)
-
- What we see here is that when using the MI a user can create
- thread-specific breakpoints for non-existent threads. Then if we try
- to use the CLI 'info breakpoints' command GDB throws an assertion.
- The assert is a result of the print_thread_id call when trying to
- build the 'stop only in thread xx.yy' line; print_thread_id requires a
- valid thread_info pointer, which we can't have for a non-existent
- thread.
-
- In contrast, when using the CLI we see this behaviour:
-
- $ gdb -q /tmp/hello.x
- Reading symbols from /tmp/hello.x...
- (gdb) break main thread 99
- Unknown thread 99.
- (gdb)
-
- The CLI doesn't allow a breakpoint to be created for a non-existent
- thread. So the 'info breakpoints' command is always fine.
-
- Interestingly, the MI -break-info command doesn't crash, this is
- because the MI uses global thread-ids, and so never calls
- print_thread_id. However, GDB does support using CLI and MI in
- parallel, so we need to solve this problem.
-
- One option would be to change the CLI behaviour to allow printing
- breakpoints for non-existent threads. This would preserve the current
- MI behaviour.
-
- The other option is to pull the MI into line with the CLI and prevent
- breakpoints being created for non-existent threads. This is good for
- consistency, but is a breaking change for the MI.
-
- In the end I figured that it was probably better to retain the
- consistent CLI behaviour, and just made the MI reject requests to
- place a breakpoint on a non-existent thread. The only test we had
- that depended on the old behaviour was
- gdb.mi/mi-thread-specific-bp.exp, which was added by me in commit:
-
- commit 2fd9a436c8d24eb0af85ccb3a2fbdf9a9c679a6c
- Date: Fri Feb 17 10:48:06 2023 +0000
-
- gdb: don't duplicate 'thread' field in MI breakpoint output
-
- I certainly didn't intend for this test to rely on this feature of the
- MI, so I propose to update this test to only create breakpoints for
- threads that exist.
-
- Actually, I've added a new test that checks the MI rejects creating a
- breakpoint for a non-existent thread, and I've also extended the test
- to run with the separate MI/CLI UIs, and then tested 'info
- breakpoints' to ensure this command doesn't crash.
-
- I've extended the documentation of the `-p` flag to explain the
- constraints better.
-
- I have also added a NEWS entry just in case someone runs into this
- issue, at least then they'll know this change in behaviour was
- intentional.
-
- One thing that I did wonder about while writing this patch, is whether
- we should treat requests like this, on both the MI and CLI, as another
- form of pending breakpoint, something like:
-
- (gdb) break foo thread 9
- Thread 9 does not exist.
- Make breakpoint pending on future thread creation? (y or [n]) y
- Breakpoint 1 (foo thread 9) pending.
- (gdb) info breakpoints
- Num Type Disp Enb Address What
- 1 breakpoint keep y <PENDING> foo thread 9
-
- Don't know if folk think that would be a useful idea or not? Either
- way, I think that would be a separate patch from this one.

- gdb: make set/show args work with $_gdb_setting_str
- I noticed that $_gdb_setting_str was not working with 'args', e.g.:
-
- $ gdb -q --args /tmp/hello.x arg1 arg2 arg3
- Reading symbols from /tmp/hello.x...
- (gdb) show args
- Argument list to give program being debugged when it is started is "arg1 arg2 arg3".
- (gdb) print $_gdb_setting_str("args")
- $1 = ""
-
- This is because the 'args' setting is implemented using a scratch
- variable ('inferior_args_scratch') which is updated when the user does
- 'set args ...'. There is then a function 'set_args_command' which is
- responsible for copying the scratch area into the current inferior.
-
- However, when the user sets the arguments via the command line the
- scratch variable is not updated, instead the arguments are pushed
- straight into the current inferior.
-
- There is a second problem, when the current inferior changes the
- scratch area is not updated, which means that the value returned will
- only ever reflect the last call to 'set args ...' regardless of which
- inferior is currently selected.
-
- Luckily, the fix is pretty easy, set/show variables have an
- alternative API which requires we provide some getter and setter
- functions. With this done the scratch variable can be removed and the
- value returned will now always reflect the current inferior.
-
- While working on set/show args I also rewrote show_args_command to
- remove the use of deprecated_show_value_hack.

- In this list, we only have entries for the beginning of each line. This

- process target reports a stop. With range stepping, the remote target
- single-steps multiple instructions at a time, so the record-full target
- doesn't get to see and record them all.
-
- Fix this by making the record-full layer disable range-stepping
- before handing the resume request to the beneath layer, forcing the
- remote target to report stops for each instruction.

- Allow strings with printf/eval
- PR 13098 explains that if a user attempts to use a string with either
- `printf' (or `eval'), gdb returns an error (inferior not running):
-
- (gdb) printf "%s\n", "hello"
- evaluation of this expression requires the target program to be active
-
- However, the parser can certainly handle this case:
-
- (gdb) p "hello"
- $1 = "hello"
-
- This discrepancy occurs because printf_c_string does not handle
- this specific case. The passed-in value that we are attempting to print
- as a string is TYPE_CODE_ARRAY but it's lval type is not_lval.
-
- printf_c_string will only attempt to print a string from the value's
- contents when !TYPE_CODE_PTR, lval is lval_internalvar, and the value's
- type is considered a string type:
-
- if (value->type ()->code () != TYPE_CODE_PTR
- && value->lval () == lval_internalvar
- && c_is_string_type_p (value->type ()))
- {
- ...
- }
-
- Otherwise, it attempts to read the value of the string from the target's
- memory (which is what actually generates the "evaluation of this ..."
- error message).

- Fix PR30358, performance with --sort-section
- since af31506c we only use the binary tree when section sorting is
- required. While its unbalanced and hence can degrade to a linear list
- it should otherwise have been equivalent to the old code relying on
- insertion sort. Unfortunately it was not. The old code directly used
- lang_add_section to populate the sorted list, the new code first
- populates the tree and only then does lang_add_section on the sorted
- result.
-
- In the testcase we have very many linkonce section groups, and hence
- lang_add_section won't actually insert anything for most of them. That
- limited the to-be-sorted list length previously. The tree-sorting code
- OTOH first created a tree of all candidates sections, including those
- that wouldn't be inserted by lang_add_section, hence increasing the size
- of the sorting problem. In the testcase the chain length went from
- about 1500 to 106000, and in the degenerated case (as in the testcase)
- that goes in quadratically.
-
- This splits out most of the early-out code from lang_add_section to its
- own function and uses the latter to avoid inserting into the tree. This
- refactoring slightly changes the order of early-out tests (the ones
- based on section flags is now done last, and only in lang_add_section).
- The new function is not a pure predicate: it can give warnings and it
- might change output_section, like the old early-out code did. I have
- also added a skip-warning case in the first discard case, whose
- non-existence seemed to have been an oversight.

- gdb/doc: extend the documentation of the jump command

-
- The bug points out that 'jump 0x...' is not always the same as 'set

- register does not update any auxiliary state, e.g. $npc on SPARC,
- while using 'jump' does.
-
- It felt like this would be an easy issue to address by adding a

- gdb/testsuite: special case '^' in gdb_test pattern
- In this commit I propose that we add special handling for the '^' when
- used at the start of a gdb_test pattern. Consider this usage:
-
- gdb_test "some_command" "^command output pattern"
-
- I think the intention here is pretty clear - run 'some_command', and
- the output from the command should be exactly 'command output
- pattern'.
-
- After the previous commit which tightened up how gdb_test matches the
- final newline and prompt we know that the only thing after the output
- pattern will be a single newline and prompt, and the leading '^'
- ensures that there's no output before 'command output pattern', so
- this will do what I want, right?
-
- ... except it doesn't. The command itself will also needs to be
- matched, so I should really write:
-
- gdb_test "some_command" "^some_command\r\ncommand output pattern"
-
- which will do what I want, right? Well, that's fine until I change
- the command and include some regexp character, then I have to write:
-
- gdb_test "some_command" \
- "^[string_to_regexp some_command]\r\ncommand output pattern"
-
- but this all gets a bit verbose, so in most cases I simply don't
- bother anchoring the output with a '^', and a quick scan of the
- testsuite would indicate that most other folk don't both either.
-
- What I propose is this: the *only* thing that can appear immediately
- after the '^' is the command converted into a regexp, so lets do that
- automatically, moving the work into gdb_test. Thus, when I write:
-
- gdb_test "some_command" "^command output pattern"
-
- Inside gdb_test we will spot the leading '^' in the pattern, and
- inject the regexp version of the command after the '^', followed by a
- '\r\n'.
-
- My hope is that given this new ability, folk will be more inclined to
- anchor their output patterns when this makes sense to do so. This
- should increase our ability to catch any unexpected output from GDB
- that appears as a result of running a particular command.
-
- There is one problem case we need to consider, sometime people do
- this:
-
- gdb_test "" "^expected output pattern"
-
- In this case no command is sent to GDB, but we are still expecting
- some output from GDB. This might be a result of some asynchronous
- event for example. As there is no command sent to GDB (from the
- gdb_test) there will be no command text to parse.
-
- In this case my proposed new feature injects the command regexp, which
- is the empty string (as the command itself is empty), but still
- injects the '\r\n' after the command regexp, thus we end up with this
- pattern:
-
- ^\r\nexpected output pattern
-
- This extra '\r\n' is not what we should expected here, and so there is
- a special case inside gdb_test -- if the command is empty then don't
- add anything after the '^' character.
-
- There are a bunch of tests that do already use '^' followed by the
- command, and these can all be simplified in this commit.
-
- I've tried to run all the tests that I can to check this commit, but I
- am certain that there will be some tests that I manage to miss.
- Apologies for any regressions this commit causes, hopefully fixing the
- regressions will not be too hard.

- gdb/testsuite: change newline patterns used in gdb_test
- This commit makes two changes to how we match newline characters in
- the gdb_test proc.
-
- First, for the newline pattern between the command output and the
- prompt, I propose changing from '[\r\n]+' to an explicit '\r\n'.
-
- The old pattern would spot multiple newlines, and so there are a few
- places where, as part of this commit, I've needed to add an extra
- trailing '\r\n' to the pattern in the main test file, where GDB's
- output actually includes a blank line.
-
- But I think this is a good thing. If a command produces a blank line
- then we should be checking for it, the current gdb_test doesn't do
- that. But also, with the current gdb_test, if a blank line suddenly
- appears in the output, this is going to be silently ignored, and I
- think this is wrong, the test should fail in that case.
-
- Additionally, the existing pattern will happily match a partial
- newline. There are a strangely large number of tests that end with a
- random '.' character. Not matching a literal period, but matching any
- single character, this is then matching half of the trailing newline
- sequence, while the \[\r\n\]+ in gdb_test is matching the other half
- of the sequence. I can think of no reason why this would be
- intentional, I suspect that the expected output at one time included a
- period, which has since been remove, but I haven't bothered to check
- on this. In this commit I've removed all these unneeded trailing '.'
- characters.
-
- The basic rule of gdb_test after this is that the expected pattern
- needs to match everything up to, but not including the newline
- sequence immediately before the GDB prompt. This is generally how the
- proc is used anyway, so in almost all cases, this commit represents no
- significant change.
-
- Second, while I was cleaning up newline matching in gdb_test, I've
- also removed the '[\r\n]*' that was added to the start of the pattern
- passed to gdb_test_multiple.
-
- The addition of this pattern adds no value. If the user pattern
- matches at the start of a line then this would match against the
- newline sequence. But, due to the '*', if the user pattern doesn't
- match at the start of a line then this group doesn't care, it'll
- happily match nothing.
-
- As such, there's no value to it, it just adds more complexity for no
- gain, so I'm removing it. No tests will need updating as a
- consequence of this part of the patch.

- gdb/testsuite: use 'return' in gdb_test_no_output
- A TCL proc will return the return value of the last command executed
- within the proc's body if there is no explicit return call, so
- gdb_test_no_output is already returning the return value of
- gdb_test_multiple.
-
- However, I'm not a fan of (relying on) this implicit return value
- behaviour -- I prefer to be explicit about what we are doing. So in
- this commit I have extended the comment on gdb_test_no_output to
- document the possible return values (just as gdb_test does), and
- explicitly call return.
-
- This should make no different to our testing, but I think it's clearer
- now what the gdb_test_no_output proc is expected to do.
-
- The two tests gdb.base/auxv.exp and gdb.base/list.exp both rely on the
- return value of gdb_test_no_output, and continue to pass after this
- change.
-
- I also spotted that gdb.base/watchpoint.exp could be updated to make

- gdb: remove some trailing newlines from warning messages
- While working on a later patch in this series, which tightens up some
- of our pattern matching when using gdb_test, I ran into some failures
- caused by some warnings having a trailing newline character.
-
- The warning function already adds a trailing newline, and it is my
- understanding that we should not be adding a second by including a
- newline at the end of any warning message.
-
- The problem cases I found were in language.c and remote.c, in this
- patch I fix the cases I hit, but I also checked all the other warning
- calls in these two files and removed any additional trailing newlines
- I found.
-
- In remote.c the warning actually had a newline character in the middle
- of the warning message (in addition to the trailing newline), which
- I've removed. I don't think it's helpful to forcibly split a warning
- as was done here -- in the middle of a sentence. Additionally, the
- message isn't even that long (71 characters), so I think removing this
- newline is an improvement.
-
- None of the expected test result need updating with this commit,
- currently the patterns in gdb_test will match one or more newline
- sequences, so the tests are as happy with one newline (after this
- commit) as they are with two newlines (before this commit). A later
- commit will change gdb_test so that it is not so forgiving, and these
- warnings would have caused some failures.

- gdb/testsuite: fix occasional failure in gdb.base/clear_non_user_bp.exp
- I noticed that the gdb.base/clear_non_user_bp.exp test would sometimes
- fail when run from a particular directory.
-
- The test tries to find the number of the first internal breakpoint
- using this proc:
-
- proc get_first_maint_bp_num { } {
- gdb_test_multiple "maint info break" "find first internal bp num" {
- -re -wrap "(-\[0-9\]).*" {
- return $expect_out(1,string)
- }
- }
- return ""
- }
-
- The problem is, at the time we issue 'maint info break' there are both
- internal breakpoint and non-internal (user created) breakpoints in
- place. The user created breakpoints include the path to the source
- file.
-
- Sometimes, I'll be working from a directory that includes a number,
- like '/tmp/blah-1/gdb/etc', in which case the pattern above actually
- matches the '-1' from 'blah-1'. In this case there's no significant
- problem as it turns out that -1 is the number of the first internal
- breakpoint.
-
- Sometimes my directory name might be '/tmp/blah-4/gdb/etc', in which
- case the above pattern patches '-4' from 'blah-4'. It turns out this
- is also not a problem -- the test doesn't actually need the first
- internal breakpoint number, it just needs the number of any internal
- breakpoint.
-
- But sometimes my directory name might be '/tmp/blah-0/gdb/etc', in
- which case the pattern above matches '-0' from 'blah-0', and in this
- case the test fails - there is no internal breakpoint '-0'.
-
- Fix this by spotting that the internal breakpoint numbers always
- occurs after a '\r\n', and that they never start with a 0. Our
- pattern becomes:
-
- -re -wrap "\r\n(-\[1-9\]\[0-9\]*).*" {
- return $expect_out(1,string)
- }
-
- After this I'm no longer seeing any failures.

- XVentanaCondOps ("conditional ops") extension at
- https://github.com/ventanamicro/ventana-custom-extensions/releases/download/v1.0.0/ventana-custom-extensions-v1.0.0.pdf
- which contains two new instructions
- - vt.maskc
- - vt.maskcn
- that can be used in constructing branchless sequences for
- various conditional-arithmetic, conditional-logical, and
- conditional-select operations.
-
- To support such vendor-defined instructions in the mainline binutils,
- this change also adds a riscv_supported_vendor_x_ext secondary
- dispatch table (but also keeps the behaviour of allowing any unknow
- X-extension to be specified in addition to the known ones from this
- table).
-
- As discussed, this change already includes the planned/agreed future
- requirements for X-extensions (which are likely to be captured in the
- riscv-toolchain-conventions repository):
- - a public specification document is available (see above) and is
- referenced from the gas-documentation
- - the naming follows chapter 27 of the RISC-V ISA specification
- - instructions are prefixed by a vendor-prefix (vt for Ventana)
- to ensure that they neither conflict with future standard
- extensions nor clash with other vendors

- everywhere in i386-dis.c except print_displacement.
-
- 2) Return get32s and get16 value in a bfd_vma, reducing the need for

- 3) Introduce get16s and get8s functions to simplify the code.
-
- 4) With some optimisation options gcc-13 legitimately complains about
- a fall-through in OP_I. Fix that. OP_I also doesn't need to use
- "mask" which was wrong for w_mode anyway.
-
- 5) Masking with & 0xffffffff is better than casting to unsigned. We
- don't know for sure that unsigned int is 32-bit.
-
- 6) We also don't know that unsigned char is 8 bits. Mask codep
- accesses everywhere. I don't expect binutils will work on anything
- other than an 8-bit char host, but if we are masking codep accesses in
- some places we might as well be consistent. (Better would be to use
- stdint.h types more in binutils.)

- section-select: Fix performance problem (PR30367)
- when using many wild-statements with non-wildcard filenames we
- were running into quadraticness via repeatedly using lookup_name
- on a long list of loaded files. I've originally retained using
- lookup_name because that preserved existing behaviour most obviously.
- In particular in matching wild-statements when using a non-wildcard
- filename it matches against local_sym_name, not the filename member.
- If the wildspec would have an archive-spec or a wildcard it would use
- the filename member, though. Also it would load the named file
- (and ignore it, as being not equal to the currently considered
- input-statement).
-
- Rewrite this to not use lookup_name but retain the comparison
- against local_sym_name with a comment to that effect.
-
- PR 30367
- * ldlang.c (walk_wild_section_match): Don't use lookup_name
- but directly compare spec and local_sym_name.

- RISC-V: adjust logic to avoid register name symbols
- Special casing GPR names in my_getSmallExpression() leads to a number of
- inconsistencies. Generalize this by utilizing the md_parse_name() hook,
- limited to when instruction operands are being parsed (really: probed).
- Then both the GPR lookup there and the yet more ad hoc workaround for
- PR/gas 29940 can be removed (including its extension needed for making
- the compressed form JAL work again).
-
- RISC-V: test for expected / no unexpected symbols
- Both the temporary workaround for PR/gas 29940 and the existing special
- casing of GPRs in my_getSmallExpression() aren't really tested anywhere
- (i.e. with the workarounds remove testing would still succeed). Nor is
- there any test for uses of symbols with names matching GPRs, where such
- is permitted. Before altering how this is to be dealt with, install two
- testcases covering the expected behavior. (For now this includes only
- known affected insns; re-ordering of entries in riscv_opcodes[] could,
- however, yield more of them.)
-
- RISC-V: don't recognize bogus relocations
- With my_getSmallExpression() consistently and silently failing on
- relocation operators not fitting an insn, it is no longer necessary to
- hand it percent_op_itype[] "just in case" (i.e. to avoid errors when a
- subsequent parsing attempt for another operand combination might
- succeed). This also eliminates the latent problem of percent_op_itype[]
- and percent_op_stype[] growing a non-identical set of recognized
- relocation operators.
-
- RISC-V: avoid redundant and misleading/wrong error messages
- The use of a wrong (for the insn) relocation operator (or a future one
- which simply isn't recognized by older gas yet) doesn't render the (rest
- of the) expression "bad". Furthermore alongside the error from
- expression() in most cases the parser would emit another error then
- anyway. Suppress the call to my_getExpression() in such a case,
- arranging for a guaranteed subsequent error message by marking the
- expression "illegal".
-
- RISC-V: drop "percent_op" parameter from my_getOpcodeExpression()
- Both callers check for no relocations, so there's no point parsing for
- some. Have the function pass percent_op_null into
- my_getSmallExpression(). Note that there's no point passing
- percent_op_itype: Elsewhere, especially when processing compressed alias
- insns ahead of non-alias ones, this has the effect of avoiding "bad
- expression" errors when another parsing pass may follow (and succeed).
- Here, however, all alternative forms of an insn type will again start
- with the same O4 or O2, so avoiding errors earlier on doesn't really
- help. Plus constructs with a relocation specifier (as percent_op_itype
- would permit) can't be specified anyway, as the scrubber eats the
- whitespace between .insn's type and the O4 or O2 expression when that
- starts with % or ( - i.e. these will be seen as e.g. "i%lo(x)", and
- riscv_ip() looks only for whitespace when finding the end of a mnemonic.
-
- RISC-V: minor effort reduction in relocation specifier parsing
- The sole caller of parse_relocation() has already checked for the %
- prefix, so there's no need to check for it again in the strncasecmp()
- and there's also no reason to make the involved string literals longer
- than necessary.

- x86: work around compiler diagnosing dangling pointer
- For quite come time print_insn() has been storing the address of a local
- variable into info->private_data. Since the compiler can't know that the
- field won't be accessed again after print_insn() returns, it may kind of
- legitimately diagnose this. And recent enough gcc does as of the
- introduction of the fetch_error() return paths (replacing setjmp()-based
- error handling).
-
- Utilizing that neither prefix_name() nor i386_dis_printf() actually use
- info->private_data, zap the pointer in fetch_error(), after having
- retrieved it for local use.

- gdb: remove language_auto
- I think that the language_auto enumerator and the auto_language class
- can be removed. There isn't really an "auto" language, it's only a
- construct of the "set language" command to say "pick the appropriate
- language automatically". But "auto" is never the current language. The
- `current_language` points to the current effective language, and the
- fact that we're in "auto language" mode is noted by the language_mode
- global.
-
- - Change set_language to handle the "auto" (and "local", which is a
- synonym) early, instead of in the for loop. I think it makes the two
- cases (auto vs explicit language) more clearly separated anyway.
-
- - Adjust add_set_language_command to hard-code the "auto" string,
- instead of using the "auto" language definition.
-
- - Remove auto_language, rename auto_or_unknown_language to
- unknown_language and move the bits of the existing unknown_language
- in there.
-
- - Remove the set_language at the end of _initialize_language. I think
- it's not needed, because we call set_language in gdb_init, after all
- _initialize functions are called. There is some chance that an
- _initialize function that runs after _initialize_language implicitly
- depends on current_language being set, but my testsuite runs haven't
- found anything like that.
-
- - Use language_unknown instead of language_auto when creating a minimal
- symbol (minimal_symbol_reader::record_full). I think that this value
- is used to indicate that we don't know the symbol of the minimal
- symbol (yet), so language_unknown makes sense to me. Update a
- condition accordingly in ada-lang.c. symbol_find_demangled_name also
- appears to "normalize" this value from "unknown" to "auto", remove
- that part and update the condition to just check for
- language_unknown.

- [gdb/testsuite] Add make-check-all.sh
- Directory gdb/testsuite/boards contains a number of host/target boards, which

- The benefits of using these boards are:
- - improving test coverage of gdb,

- Each board is slightly different, and developers need to learn how to use each

- [gdb/cli] Add maint info screen
- While working on PRs tui/30337 and cli/30346 I came across various notions of
- width in gdb, as reported by gdb, readline, curses and the environment
- variables.
-
- As for gdb, readline and the environment variables, the way things work
- is:
- - Gdb asks readline to detect screen size,
- - readline sets the actual screen size in the environment variables
- COLUMNS and LINES,
- - readline reports back a screen size to gdb, which may have one column
- less than the actual screen size, to deal with lack of auto-wrap.
- This becomes gdb's notion of screen size (in other words the point where
- we can expect the gdb command line to wrap),
- - Gdb then explicitly sets readline's screen size, which readline itself may
- adjust to deal with lack of auto-wrap. This becomes readlines notion
- of screen size (well, internally the unadjusted one, but it'll report back
- the adjusted one).
-
- Add a command "maint info screen" that prints these notions, both for width
- and height.
-
- For TERM=xterm we have:
- ...
- $ TERM=xterm gdb -ex "maint info screen"
- Number of characters gdb thinks are in a line is 118.
- Number of characters readline reports are in a line is 118.
- Number of characters curses thinks are in a line is 118.
- Number of characters environment thinks are in a line is 118 (COLUMNS).
- Number of lines gdb thinks are in a page is 27.
- Number of lines readline reports are in a page is 27.
- Number of lines curses thinks are in a page is 27.
- Number of lines environment thinks are in a page is 27 (LINES).
- ...
-
- And for TERM=ansi:
- ...
- $ TERM=ansi gdb -ex "maint info screen"
- Number of characters gdb thinks are in a line is 117.
- Number of characters readline reports are in a line is 116.
- Number of characters curses thinks are in a line is 118.
- Number of characters environment thinks are in a line is 118 (COLUMNS).
- Number of lines gdb thinks are in a page is 27.
- Number of lines readline reports are in a page is 27.
- Number of lines curses thinks are in a page is 27.
- Number of lines environment thinks are in a page is 27 (LINES).
- ...
-
- [ The fact that we have "characters readline reports are in a line is 116" is
- is due to gdb making readline adjust twice for the lack of auto-wrap, this is
- PR cli/30346.
-
- Likewise we can detect tui/30337 by doing a resize in TUI mode and doing
- "maint info screen":
- ...
- Number of characters characters curses thinks are in a line is 110.
- Number of characters environment thinks are in a line is 111 (COLUMNS). ]
-
- And for TERM=ansi, with width and heigth set to 0:
- ...
- Number of characters gdb thinks are in a line is 4294967295 (unlimited).
- Number of characters readline reports are in a line is 32766 (unlimited - 1).
- Number of characters curses thinks are in a line is 118.
- Number of characters environment thinks are in a line is 118 (COLUMNS).

- Number of lines readline reports are in a page is 32767 (unlimited).
- Number of lines curses thinks are in a page is 27.
- Number of lines environment thinks are in a page is 27 (LINES).
- ...
-
- [ Note that when doing a resize by say maximizing or de-maximizing a terminal,
- all reported values are updated, except for curses when not in TUI mode.
-
- Maybe that means there's a bug. If not, then maybe we should not print
- the curses lines unless in TUI mode, or annotate those lines such that it's
- clear that the values may be not up-to-date. ]

- Use entry values for 32-bit PPC struct return
- AdaCore has a local patch for PPC "finish", but last year, Ulrich
- Weigand pointed out that this patch was incorrect. It may work for
- simple functions like the one in the internal test, but nothing
- guarantees that r3 will be preserved by the callee, so checking r3 on
- exit is not always correct.
-
- This patch fixes the problem using the same approach as PPC64: use the
- entry value of r3, if available. Ulrich confirmed this matches the
- PPC32 ABI.

-
- Handle erroneous DW_AT_call_return_pc
- On PPC64, with the test case included in an earlier patch, we found
- that "finish" would still not correctly find the return value via
- entry values.
-
- The issue is simple. The compiler emits:
-
- 0x00000000100032b8 <+28>: bl 0x1000320c <pck__create_large>
- 0x00000000100032bc <+32>: nop
- 0x00000000100032c0 <+36>: li r9,42
-
- ... but the DWARF says:
-
- <162a> DW_AT_call_return_pc: 0x100032c0
-
- That is, the declared return PC is one instruction past the actual
- return PC.
-
- This patch adds a new arch hook to handle this scenario, and
- implements it for PPC64. Some care is taken so that GDB will continue
- to work if this compiler bug is fixed. A GCC patch is here:
-
- https://gcc.gnu.org/pipermail/gcc-patches/2023-March/613336.html

- No check for 'nop' is done, as subsequent discussion revealed that the
- linker might replace this with another instruction.

- to convert from a function descriptor to the address recorded at the
- call site.
-
- I've added a new test case that is based on the internal AdaCore test
- that provoked this bug. However, I'm unable to test it as-is on

- RISC-V: Optimize relaxation of gp with max_alignment.
- This should be the first related issue, which posted in riscv-gnu-toolchain,
- https://github.com/riscv-collab/riscv-gnu-toolchain/issues/497
-
- If the output sections are not between gp and the symbol, then their alignments
- shouldn't affect the gp relaxation. However, this patch improves this idea
- even more, it limits the range to the gp+-2k, which means only the output
- section which are in the [gp-2K, gp+2K) range need to be considered.
-
- Even if the output section candidates may be different for each relax passes,
- the symbol that can be relaxed ar this round will not be truncated at next
- round. That is because this round you can do relaxation which means that the
- section where the symbol is located is within the [gp-2K, gp+2K) range, so all
- the output section alignments between them should be considered. In other
- words, if the alignments between them may cause truncated, then we should
- already preserve the size and won't do the gp relaxation this time.
-
- This patch can resolve the github issue which mentioned above, and also passed
- all gcc/binutils regressions of riscv-gnu-toolchain, so should be worth and
- safe enough to commit.
-
- Originally, this patch also do the same optimization for the call relaxations,
- https://sourceware.org/pipermail/binutils/2022-October/123918.html
- But just in case there is something that has not been considered, we only
- deal with the gp relaxation at this time.

- Keeping track of rs6000-coff archive element pointers
- rs6000-coff archives use a linked list of file offsets, where each
- element points to the next element. The idea is to allow updating of
- large archives quickly without rewriting the whole archive. (binutils
- ar does not do this.) Unfortunately this is an easy target for
- fuzzers to create an archive that will cause ar or any other tool
- processing archives to hang. I'd implemented guards against pointing
- back to the previous element, but of course that didn't last long.
-
- So this patch implements a scheme to keep track of file offset ranges
- used by elements as _bfd_read_ar_hdr is called for each element. See
- the add_range function comment. I needed a place to stash the list,
- so chose the obvious artdata.tdata backend extension to archive's
- tdata, already used by xcoff. That involved a little cleanup, because
- while it would be possible to continue using different artdata.tdata
- for the big and small archives, it's nicer to use a union.
-
- If anyone is concerned this list of element ranges might grow large
- and thus significantly slow down the tools, adjacent ranges are
- merged. In fact something like "ar t" will only ever have one range
- on xcoff archives generated by binutils/ar. I agree there might still

- PowerPC: fix _Float128 type output string
- PowerPC supports two 128-bit floating point formats, the IBM long double
- and IEEE 128-bit float. The issue is the DWARF information does not
- distinguish between the two. There have been proposals of how to extend
- the DWARF information as discussed in
-
- https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104194
-
- but has not been fully implemented.
-
- GCC introduced the _Float128 internal type as a work around for the issue.
- The workaround is not transparent to GDB. The internal _Float128 type
- name is printed rather then the user specified long double type. This
- patch adds a new gdbarch method to allow PowerPC to detect the GCC
- workaround. The workaround checks for "_Float128" name when reading the
- base typedef from the die_info. If the workaround is detected, the type
- and format fields from the _Float128 typedef are copied to the long
- double typedef. The same is done for the complex long double typedef.
-
- This patch fixes 74 regression test failures in
- gdb.base/whatis-ptype-typedefs.exp on PowerPC with IEEE float 128 as the
- default on GCC. It fixes one regression test failure in
- gdb.base/complex-parts.exp.
-
- The patch has been tested on Power 10 where GCC defaults to IEEE Float
- 128-bit and on Power 10 where GCC defaults to the IBM 128-bit float. The
- patch as also been tested on X86-64 with no new regression failures.

- RISC-V: Cache the latest mapping symbol and its boundary.
- This issue was reported from https://github.com/riscv-collab/riscv-gnu-toolchain/issues/1188
-
- Current flow:
- 1) Scan any mapping symbol less than this instruciton.
- 2) If not found, did a backward search.
-
- The flow seems not big issue, let run an example here:
-
- $x:
- 0x0 a <--- Found at step 1
- 0x4 b <--- Not found in step 1, but found at step 2
- 0x8 c <--- Not found in step 1, but found at step 2
- $d
- 0x12 .word 1234 <-- Found at step 1
-
- The instruciton didn't have the same address with mapping symbol will
- still did backward search again and again.
-
- So the new flow is:
- 1) Use the last mapping symbol status if the address is still within the range
- of the current mapping symbol.
- 2) Scan any mapping symbol less than this instruciton.
- 3) If not found, did a backward search.
- 4) If a proper mapping symbol is found in either step 2 or 3, find its boundary,
- and cache that.
-
- Use the same example to run the new flow again:
-
- $x:
- 0x0 a <--- Found at step 2, the boundary is 0x12
- 0x4 b <--- Cache hit at step 1, within the boundary.
- 0x8 c <--- Cache hit at step 1, within the boundary.
- $d
- 0x12 .word 1234 <-- Found at step 2, the boundary is the end of section.
-
- The disassemble time of the test cases has been reduced from ~20 minutes to ~4
- seconds.

- 000000000004b5e0 T pthread_create@GLIBC_2.0
-
- Our library does not set the default version for symbols.
- This is correct because we don't know which libC will be used.
-
- gcc and g++ links differently the version symbols when the default version is
- not set. c-linker is using our pthread_create@GLIBC_2.34 and c++-linker is using
- our pthread_create@GLIBC_2.0 by default.
-
- The current implementation of the interposed functions is:
- If we are in our pthread_create@GLIBC_<NN>,
- we use dlvsym (dlflag, "pthread_create", "GLIBC_<NN>") to find and call
- the same function from libC.
- In the test from PR 30360, pthread_create@GLIBC_2.0 is not in the current libC.

- gdb/amdgpu: add follow fork and exec support
- Prior to this patch, it's not possible for GDB to debug GPU code in fork
- children or after an exec. The amd-dbgapi target attaches to processes
- when an inferior appears due to a "run" or "attach" command, but not
- after a fork or exec. This patch adds support for that, such that it's
- possible to for an inferior to fork and for GDB to debug the GPU code in
- the child.
-
- To achieve that, use the inferior_forked and inferior_execd observers.
-
- In the case of fork, we have nothing to do if `child_inf` is nullptr,
- meaning that GDB won't debug the child. We also don't attach if the
- inferior has vforked. We are already attached to the parent's address
- space, which is shared with the child, so trying to attach would cause
- problems. And anyway, the inferior can't do anything other than exec or
- exit, it certainly won't start GPU kernels before exec'ing.
-
- In the case of exec, we detach from the exec'ing inferior and attach to
- the following inferior. This works regardless of whether they are the
- same or not. If they are the same, meaning the execution continues in
- the existing inferior, we need to do a detach/attach anyway, as
- amd-dbgapi needs to be aware of the new address space created by the
- exec.
-
- Note that we use observers and not target_ops::follow_{fork,exec} here.
- When the amd-dbgapi target is compiled in, it will attach (in the
- amd_dbgapi_process_attach sense, not the ptrace sense) to native
- inferiors when they appear, but won't push itself on the inferior's
- target stack just yet. It only pushes itself if the inferior
- initializes the ROCm runtime. So, if a non-GPU-using inferior calls
- fork, an amd_dbgapi_target::follow_fork method would not get called.
- Same for exec. A previous version of the code had the amd-dbgapi target
- pushed all the time, in which case we could use the target methods. But
- we prefer having the target pushed only when necessary, it's less
- intrusive when doing native debugging that doesn't involve the GPU.

- gdb: switch to right inferior in fetch_inferior_event
- The problem explained and fixed in the previous patch could have also
- been fixed by this patch. But I think it's good change anyhow, that
- could prevent future bugs, so here it is.
-
- fetch_inferior_event switches to an arbitrary (in practice, the first) inferior
- of the process target of the inferior used to fetch the event. The idea is
- that the event handling code will need to do some target calls, so we want to
- switch to an inferior that has target target.
-
- However, you can have two inferiors that share a process target, but with one
- inferior having an additional target on top:
-
- inf 1 inf 2
- ----- -----
- another target
- process target process target
- exec exec
-
- Let's say inferior 2 is selected by do_target_wait and returns an event that is
- really synthetized by "another target". This "another target" could be a
- thread or record stratum target (in the case explained by the previous patch,
- it was the arch stratum target, but it's because the amd-dbgapi abuses the arch
- layer). fetch_inferior_event will then switch to the first inferior with
- "process target", so inferior 1. handle_signal_stop then tries to fetch the
- thread's registers:
-
- ecs->event_thread->set_stop_pc
- (regcache_read_pc (get_thread_regcache (ecs->event_thread)));
-
- This will try to get the thread's register by calling into the current target
- stack, the stack of inferior 1. This is problematic because "another target"
- might have a special fetch_registers implementation.
-
- I think it would be a good idea to switch to the inferior for which the
- even was reported, not just some inferior of the same process target.
- This will ensure that any target call done before we eventually call
- context_switch will be done on the full target stack that reported the
- event.
-
- Not all events are associated to an inferior though. For instance,
- TARGET_WAITKIND_NO_RESUMED. In those cases, some targets return
- null_ptid, some return minus_one_ptid (ideally the expected return value
- should be clearly defined / documented). So, if the ptid returned is
- either of these, switch to an arbitrary inferior with that process
- target, as before.

- gdb: make regcache::raw_update switch to right inferior
- With the following patch, which teaches the amd-dbgapi target to handle
- inferiors that fork, we end up with target stacks in the following
- state, when an inferior that does not use the GPU forks an inferior that
- eventually uses the GPU.
-
- inf 1 inf 2
- ----- -----
- amd-dbgapi
- linux-nat linux-nat
- exec exec
-
- When a GPU thread from inferior 2 hits a breakpoint, the following
- sequence of events would happen, if it was not for the current patch.
-
- - we start with inferior 1 as current
- - do_target_wait_1 makes inferior 2 current, does a target_wait, which
- returns a stop event for an amd-dbgapi wave (thread).
- - do_target_wait's scoped_restore_current_thread restores inferior 1 as
- current
- - fetch_inferior_event calls switch_to_target_no_thread with linux-nat
- as the process target, since linux-nat is officially the process
- target of inferior 2. This makes inferior 1 the current inferior, as
- it's the first inferior with that target.
- - In handle_signal_stop, we have:
-
- ecs->event_thread->suspend.stop_pc
- = regcache_read_pc (get_thread_regcache (ecs->event_thread));
-
- context_switch (ecs);
-
- regcache_read_pc executes while inferior 1 is still the current one
- (because it's before the `context_switch`). This is a problem,
- because the regcache is for a ptid managed by the amd-dbgapi target
- (e.g. (12345, 1, 1)), a ptid that does not make sense for the
- linux-nat target. The fetch_registers target call goes directly
- to the linux-nat target, which gets confused.
- - We would then get an error like:
-
- Couldn't get extended state status: No such process.
-
- ... since linux-nat tries to do a ptrace call on tid 1.
-
- GDB should switch to the inferior the ptid belongs to before doing the
- target call to fetch registers, to make sure the call hits the right
- target stack (it should be handled by the amd-dbgapi target in this
- case). In fact the following patch does this change, and it would be
- enough to fix this specific problem.
-
- However, I propose to change regcache to make it switch to the right
- inferior, if needed, before doing target calls. That makes the
- interface as a whole more independent of the global context.
-
- My first attempt at doing this was to find an inferior using the process
- stratum target and the ptid that regcache already knows about:
-
- gdb::optional<scoped_restore_current_thread> restore_thread;
- inferior *inf = find_inferior_ptid (this->target (), this->ptid ());
- if (inf != current_inferior ())
- {
- restore_thread.emplace ();
- switch_to_inferior_no_thread (inf);
- }
-
- However, this caused some failures in fork-related tests and gdbserver
- boards. When we detach a fork child, we may create a regcache for the
- child, but there is no corresponding inferior. For instance, to restore
- the PC after a displaced step over the fork syscall. So
- find_inferior_ptid would return nullptr, and
- switch_to_inferior_no_thread would hit a failed assertion.
-
- So, this patch adds to regcache the information "the inferior to switch
- to to makes target calls". In typical cases, it will be the inferior
- that matches the regcache's ptid. But in some cases, like the detached
- fork child one, it will be another inferior (in this example, it will be
- the fork parent inferior).
-
- The problem that we witnessed was in regcache::raw_update specifically,
- but I looked for other regcache methods doing target calls, and added
- the same inferior switching code to raw_write too.
-
- In the regcache constructor and in get_thread_arch_aspace_regcache,
- "inf_for_target_calls" replaces the process_stratum_target parameter.
- We suppose that the process stratum target that would be passed
- otherwise is the same that is in inf_for_target_calls's target stack, so
- we don't need to pass both in parallel. The process stratum target is
- still used as a key in the `target_pid_ptid_regcache_map` map, but
- that's it.
-
- There is one spot that needs to be updated outside of the regcache code,
- which is the path that handles the "restore PC after a displaced step in
- a fork child we're about to detach" case mentioned above.
-
- regcache_test_data needs to be changed to include full-fledged mock
- contexts (because there now needs to be inferiors, not just targets).

- gdb: remove regcache::target
- The regcache class takes a process_stratum_target and then exposes it
- through regcache::target. But it doesn't use it itself, suggesting it
- doesn't really make sense to put it there. The only user of
- regcache::target is record_btrace_target::fetch_registers, but it might
- as well just get it from the current target stack. This simplifies a

- gdb: add inferior_forked observable
- In the upcoming patch to support fork in the amd-dbgapi target, the
- amd-dbgapi target will need to be notified of fork events through an
- observer, to attach itself (attach in the amd-dbgapi sense, not ptrace
- sense) to the new inferior / process.
-
- The reason that this can't be done through target_ops::follow_fork is
- that the amd-dbgapi target isn't pushed on the inferior's target stack
- right away. It attaches itself to the process and only pushes itself on
- its target stack if and when the inferior initializes the ROCm runtime.
-
- If an inferior that is not using the ROCm runtime forks, we want to be
- notified of it, so we can attach to the child, and catch if the child
- starts using the ROCm runtime.
-
- So, add a new observable and notify it in follow_fork_inferior. It will
- be used later in this series.

- pauth: Create new feature string for pauth to prevent crashing older gdb's
- Older gdb's (9, 10, 11 and 12) have a bug that causes them to crash whenever
- a target reports the pauth feature string in the target description and also
- provide additional register outside of gdb's known and expected feature
- strings.
-
- This was fixed in gdb 13 onwards, but that means we're stuck with gdb's out
- there that will crash on connection to the above targets.
-
- QEMU has postponed inclusion of the pauth feature string in version 8, and
- instead we agreed to use a new feature name to prevent crashing those older
- gdb's.
-
- Initially there was a plan to backport a trivial fix all the way to gdb 9, but
- given QEMU's choice, this is no longer needed.
-
- This new feature string is org.gnu.gdb.aarch64.pauth_v2, and should be used
- by all targets going forward, except native linux gdb and gdbserver, for
- backwards compatibility with older gdb's/gdbserver's.
-
- gdb/gdbserver will still emit the old feature string for Linux since it doesn't
- report additional system registers and thus doesn't cause a crash of older
- gdb's. We can revisit this in the future once the problematic gdb's are likely
- no longer in use.

- gdb/testsuite: Skip dump ihex for 64-bit address in gdb.base/dump.exp
- (1) Description of problem
-
- In the current code, when execute the following test on LoongArch:
-
- $make check-gdb TESTS="gdb.base/dump.exp"
- ```
- FAIL: gdb.base/dump.exp: dump array as value, intel hex
- FAIL: gdb.base/dump.exp: dump struct as value, intel hex
- FAIL: gdb.base/dump.exp: dump array as memory, ihex
- FAIL: gdb.base/dump.exp: dump struct as memory, ihex
-
- ```
- These tests passed on the X86_64,
-
- (2) Root cause
-
- On LoongArch, variable intarray address 0x120008068 out of range for IHEX,
- so dump ihex test failed.
-
- gdb.base/dump.exp has the following code to check 64-bit address
-
- ```
- # Check the address of a variable. If it is bigger than 32-bit,
- # assume our target has 64-bit addresses that are not supported by SREC,
- # IHEX and TEKHEX. We skip those tests then.
- set max_32bit_address "0xffffffff"
- set data_address [get_hexadecimal_valueof "&intarray" 0x100000000]
- if {${data_address} > ${max_32bit_address}} {
- set is64bitonly "yes"
- }
- ```
-
- We check the "&intarray" on different target as follow:
-
- ```
- $gdb gdb/testsuite/outputs/gdb.base/dump/dump
- ...
- (gdb) start
- ...
-
- On X86_64:
- (gdb) print /x &intarray
- $1 = 0x404060
-
- On LoongArch:
- (gdb) print /x &intarray
- $1 = 0x120008068
- ```
- The variable address difference here is due to the link script
- of linker.
-
- ```
- On X86_64:
- $ld --verbose
- ...
- PROVIDE (__executable_start = SEGMENT_START("text-segment", 0x400000));
- . = SEGMENT_START("text-segment", 0x400000) + SIZEOF_HEADERS;
-
- On LoongArch:
- $ld --verbose
- ...
- PROVIDE (__executable_start = SEGMENT_START("text-segment", 0x120000000));
- . = SEGMENT_START("text-segment", 0x120000000) + SIZEOF_HEADERS;
-
- ```
-
- (3) How to fix
-
- Because 64-bit variable address out of range for IHEX, it's not an
- functional problem for LoongArch. Refer to the handling of 64-bit
- targets in this testsuite, use the "is64bitonly" flag to skip those
- tests for the target has 64-bit addresses.

- Note the space between "B+>" and 0x555555555151. The space shows that a bit
- of the left margin is not written, which is a problem because that location is
- showing a character previously written, which happens to be a space, but also
- may be something else, for instance a '[' as reported in PR tui/30325.
-
- The problem is caused by confusion about the meaning of:
- ...
- #define TUI_EXECINFO_SIZE 4
- ...
-
- There's the meaning of defining the size of this zero-terminated char array:
- ...
- char element[TUI_EXECINFO_SIZE];
- ...
- which is used to print the "B+>" bit, which is 3 chars wide.
-
- And there's the meaning of defining part of the size of the left margin:
- ...
- int left_margin () const
- { return 1 + TUI_EXECINFO_SIZE + extra_margin (); }
- ...
- where it represents 4 chars.
-
- The discrepancy between the two causes the space between "B+>" and
- "0x555555555151".
-
- Fix this by redefining TUI_EXECINFO_SIZE to 3, and using:
- ...
- char element[TUI_EXECINFO_SIZE + 1];
- ...
- such that we have:
- ...

- [gdb/tui] Add maint set/show tui-left-margin-verbose
- The TUI has two types of windows derived from tui_source_window_base:
- - tui_source_window (the source window), and
- - tui_disasm_window (the disassembly window).
-
- The two windows share a common concept: the left margin.
-
- With a hello world a.out, we can see the source window:
- ...
- ┌─/home/vries/hello.c───────────────────────────────────────┐
- │ 5 { │
- │B+> 6 printf ("hello\n"); │
- │ 7 return 0; │
- │ 8 } │
- │ 9 │

- ...
- where the left margin is the part holding "B+>" and the line number, and the
- disassembly window:
- ...
- ┌───────────────────────────────────────────────────────────┐
- │ 0x555555555149 <main> endbr64 │
- │ 0x55555555514d <main+4> push %rbp │
- │ 0x55555555514e <main+5> mov %rsp,%rbp │
- │B+> 0x555555555151 <main+8> lea 0xeac(%rip),%rax│
- │ 0x555555555158 <main+15> mov %rax,%rdi │
- ...
- where the left margin is just the bit holding "B+>".
-
- Because the left margin contains some spaces, it's not clear where it starts
- and ends, making it harder to observe problems related to it.
-
- Add a new maintenance command "maint set tui-left-margin-verbose", that when
- set to on replaces the spaces in the left margin with either '_' or '0',
- giving us this for the source window:
- ...
- ┌─/home/vries/hello.c───────────────────────────────────────┐
- │___000005__{ │
- │B+>000006__ printf ("hello\n"); │
- │___000007__ return 0; │
- │___000008__} │
- ...
- and this for the disassembly window:
- ...
- ┌───────────────────────────────────────────────────────────┐
- │___ 0x555555555149 <main> endbr64 │
- │___ 0x55555555514d <main+4> push %rbp │
- │___ 0x55555555514e <main+5> mov %rsp,%rbp │
- │B+> 0x555555555151 <main+8> lea 0xeac(%rip),%rax│
- │___ 0x555555555158 <main+15> mov %rax,%rdi │
- ...
-
- Note the space between "B+>" and 0x555555555151. The space shows that a bit
- of the left margin is not written, a problem reported as PR tui/30325.
-
- Specifically, PR tui/30325 is about the fact that the '[' character from the
- string "[ No Assembly Available ]" ends up in that same spot:
- ...
- │B+>[0x555555555151 <main+8> lea 0xeac(%rip),%rax│
- ...
- which only happens for certain window widths.
-
- The new command allows us to spot the problem with any window width.
-
- Likewise, when we revert the fix from commit 1b6d4bb2232 ("Redraw both spaces
- between line numbers and source code"), we have:
- ...
- ┌─/home/vries/hello.c───────────────────────────────────────┐
- │___000005_ { │
- │B+>000006_ printf ("hello\n"); │
- │___000007_ return 0; │

- showing a similar problem at the space between '_' and '{'.

- MIPS: make mipsisa32 and mipsisa64 link more systematic
- Introduce `static const struct mips_mach_extension mips_mach_32_64[]`
- and `mips_mach_extends_32_64 (unsigned long base, unsigned long extension)`,
- to make mipsisa32 and mipsisa64 interlink more systemtic.
-
- Normally, the ISA mipsisa64rN has two subset: mipsisa64r(N-1) and
- mipsisa32rN. `mips_mach_extensions` can hold only mipsisa64r(N-1),
- so we need to introduce a new instruction `mips_mach_32_64`, which holds the pair 32vs64.
-
- Note: R6 is not compatible with pre-R6.

- PR30326, uninitialised value in objdump compare_relocs
- This is a fuzzing PR, with a testcase involving a SHF_ALLOC and
- SHF_COMPRESSED SHT_RELA section, ie. a compressed dynamic reloc
- section. BFD doesn't handle compressed relocation sections, with most
- of the code reading relocs using sh_size (often no bfd section is
- created) but in the case of SHF_ALLOC dynamic relocs we had some code
- using the bfd section size. This led to a mismatch, sh_size is
- compressed, size is uncompressed, and from that some uninitialised
- memory. Consistently using sh_size is enough to fix this PR, but I've
- also added tests to exclude SHF_COMPRESSED reloc sections from

- pe_ILF_object_p and bfd_check_format_matches
- If pe_ILF_object_p succeeds, pe_ILF_build_a_bfd will have changed the
- bfd from being file backed to in-memory. This can have unfortunate
- results for targets checked by bfd_check_format_matches after that
- point as they will be matching against the created in-memory image
- rather than the file. bfd_preserve_restore also has a problem if it
- flips the BFD_IN_MEMORY flag, because the flag affects iostream
- meaning and should be set if using _bfd_memory_iovec. To fix these
- problems, save and restore iostream and iovec along with flags, and
- modify bfd_reinit to make the bfd file backed again. Restoring the
- iovec and iostream allows the hack in bfd_reinit keeping BFD_IN_MEMORY
- (part of BFD_FLAGS_SAVED) to be removed.
- One more detail: If restoring from file backed to in-memory then the
- bfd needs to be forcibly removed from the cache lru list, since after
- the bfd becomes in-memory a bfd_close will delete the bfd's memory
- leaving the lru list pointing into freed memory.

- bfd: optimize bfd_elf_hash
- The bfd_elf_hash loop is taken straight from the sysV document, but it
- is poorly optimized. This refactoring removes about 5 x86 insns from
- the 15 insn loop.
-
- 1) The if (..) is meaningless -- we're xoring with that value, and of
- course xor 0 is a nop. On x86 (at least) we actually compute the xor'd
- value and then cmov. Removing the if test removes the cmov.
-
- 2) The 'h ^ g' to clear the top 4 bits is not needed, as those 4 bits
- will be shifted out in the next iteration. All we need to do is sink
- a mask of those 4 bits out of the loop.
-
- 3) anding with 0xf0 after shifting by 24 bits can allow betterin
- encoding on RISC ISAs than masking with '0xf0 << 24' before shifting.
- RISC ISAs often require materializing larger constants.

- gdb: warn when converting h/w watchpoints to s/w
- On amd64 (at least) if a user sets a watchpoint before the inferior
- has started then GDB will assume that a hardware watchpoint can be
- created.
-
- When the inferior starts there is a chance that the watchpoint can't
- actually be create as a hardware watchpoint, in which case (currently)
- GDB will silently convert the watchpoint to a software watchpoint.
- Here's an example session:
-
- (gdb) p sizeof var
- $1 = 4000
- (gdb) watch var
- Hardware watchpoint 1: var
- (gdb) info watchpoints
- Num Type Disp Enb Address What
- 1 hw watchpoint keep y var
- (gdb) starti
- Starting program: /home/andrew/tmp/watch
-
- Program stopped.
- 0x00007ffff7fd3110 in _start () from /lib64/ld-linux-x86-64.so.2
- (gdb) info watchpoints
- Num Type Disp Enb Address What
- 1 watchpoint keep y var
- (gdb)
-
- Notice that before the `starti` command the watchpoint is showing as a
- hardware watchpoint, but afterwards it is showing as a software
- watchpoint. Additionally, note that we clearly told the user we
- created a hardware watchpoint:
-
- (gdb) watch var
- Hardware watchpoint 1: var
-
- I think this is bad. I used `starti`, but if the user did `start` or
- even `run` then the inferior is going to be _very_ slow, which will be
- unexpected -- after all, we clearly told the user that we created a
- hardware watchpoint, and the manual clearly says that hardware
- watchpoints are fast (at least compared to s/w watchpoints).
-
- In this patch I propose adding a new warning which will be emitted
- when GDB downgrades a h/w watchpoint to s/w. The session now looks
- like this:
-
- (gdb) p sizeof var
- $1 = 4000
- (gdb) watch var
- Hardware watchpoint 1: var
- (gdb) info watchpoints
- Num Type Disp Enb Address What
- 1 hw watchpoint keep y var
- (gdb) starti
- Starting program: /home/andrew/tmp/watch
- warning: watchpoint 1 downgraded to software watchpoint
-
- Program stopped.
- 0x00007ffff7fd3110 in _start () from /lib64/ld-linux-x86-64.so.2
- (gdb) info watchpoints
- Num Type Disp Enb Address What
- 1 watchpoint keep y var
- (gdb)
-
- The important line is:
-
- warning: watchpoint 1 downgraded to software watchpoint
-
- It's not much, but hopefully it will be enough to indicate to the user
- that something unexpected has occurred, and hopefully, they will not
- be surprised when the inferior runs much slower than they expected.
-
- I've added an amd64 only test in gdb.arch/, I didn't want to try
- adding this as a global test as other architectures might be able to
- support the watchpoint request in h/w.
-
- Also the test is skipped for extended-remote boards as there's a
- different set of options for limiting hardware watchpoints on remote
- targets, and this test isn't about them.

- gdb/riscv: Support c.li in prologue unwinder
- I was seeing some failures in gdb.threads/omp-par-scope.exp when run
- on a riscv64 target. It turns out the cause of the problem is that I
- didn't have debug information installed for libgomp.so, which this
- test makes use of. The test requires GDB to backtrace through a
- libgomp function, and the riscv prologue unwinder was failing to
- unwind this particular stack frame.
-
- The reason for the failure to unwind was that the function prologue
- includes a c.li (compressed load immediate) instruction, and the riscv
- prologue scanning unwinder doesn't know what to do with this
- instruction, though the unwinder does understand c.lui (compressed
- load unsigned immediate).
-
- This commit adds support for c.li. After this GDB is able to unwind
- through libgomp, and I no longer see any unexpected failures in
- gdb.threads/omp-par-scope.exp.
-
- I've also included a new test in gdb.arch/ which specifically checks
- for our c.li support.

- libctf, link: fix CU-mapped links with CTF_LINK_EMPTY_CU_MAPPINGS
- This is a bug in the intersection of two obscure options that cannot
- even be invoked from ld with a feature added to stop ld of the
- same input file repeatedly from crashing the linker.
-
- The latter fix involved tracking input files (internally to libctf) not
- just with their input CU name but with a version of their input CU name
- that was augmented with a numeric prefix if their linker input file name
- was changed, to prevent distinct CTF dicts with the same cuname from
- overwriting each other. (We can't use just the linker input file name
- because one linker input can contain many CU dicts, particularly under
- ld -r). If these inputs then produced conflicting types, those types
- were emitted into similarly-named output dicts, so we needed similar
- machinery to detect clashing output dicts and add a numeric prefix to
- them as well.
-
- This works fine, except that if you used the cu-mapping feature to force
- double-linking of CTF (so that your CTF can be grouped into output dicts
- larger than a single translation unit) and then also used
- CTF_LINK_EMPTY_CU_MAPPINGS to force every possible output dict in the
- mapping to be created (even if empty), we did the creation of empty dicts
- first, and then all the actual content got considered to be a clash. So
- you ended up with a pile of useless empty dicts and then all the content
- was in full dicts with the same names suffixed with a #0. This seems
- likely to confuse consumers that use this facility.
-
- Fixed by generating all the EMPTY_CU_MAPPINGS empty dicts after linking
- is complete, not before it runs.
-
- No impact on ld, which does not do cu-mapped links or pass
- CTF_LINK_EMPTY_CU_MAPPINGS to ctf_link().

- * ctf-link.c (ctf_create_per_cu): Don't create new dicts iff one

-
- libctf: propagate errors from parents correctly
- CTF dicts have per-dict errno values: as with other errno values these
- are set on error and left unchanged on success. This means that all
- errors *must* set the CTF errno: if a call leaves it unchanged, the
- caller is apt to find a previous, lingering error and misinterpret
- it as the real error.
-
- There are many places in libctf where we carry out operations on parent
- dicts as a result of carrying out other user-requested operations on
- child dicts (e.g. looking up information on a pointer to a type will
- look up the type as well: the pointer might well be in a child and the
- type it's a pointer to in the parent). Those operations on the parent
- might fail; if they do, the error must be correctly reflected on the
- child that the user-visible operation was carried out on. In many
- places this was not happening.
-
- So, audit and fix all those places. Add tests for as many of those
- cases as possible so they don't regress.

- gdb: fix reg corruption from displaced stepping on amd64
-
- Added two test scripts gdb.arch/amd64-disp-step-self-call.exp and
- gdb.arch/i386-disp-step-self-call.exp. These scripts contained a test
- that included a stack address in the test name, this makes it harder
- to compare results between runs.
-
- This commit gives the tests proper names that doesn't include an
- address.
-
- Also in gdb.arch/i386-disp-step-self-call.exp I noticed that we were
- writing 8-bytes rather than 4 in order to clear the return address
- entry on the stack. This is also fixed in this commit.

- Fix gdb.base/align-*.exp and Clang + LTO and AIX GCC
- Clang with LTO (clang -flto) garbage collects unused global variables,
- Thus, gdb.base/align-c.exp and gdb.base/align-c++.exp fail with
- hundreds of FAILs like so:
-
- $ make check \
- TESTS="gdb.*/align-*.exp" \
- RUNTESTFLAGS="CC_FOR_TARGET='clang -flto' CXX_FOR_TARGET='clang++ -flto'"
- ...
- FAIL: gdb.base/align-c.exp: get integer valueof "a_char"
- FAIL: gdb.base/align-c.exp: print _Alignof(char)
- FAIL: gdb.base/align-c.exp: get integer valueof "a_char_x_char"
- FAIL: gdb.base/align-c.exp: print _Alignof(struct align_pair_char_x_char)
- FAIL: gdb.base/align-c.exp: get integer valueof "a_char_x_unsigned_char"
- ...
-
- AIX GCC has the same issue, and there the easier way of adding
- __attribute__((used)) to globals does not help.
-
- So add explicit uses of all globals to the generated code.
-
- For the C++ test, that reveals that the static variable members of the
- generated structs are not defined anywhere, leading to undefined
- references. Fixed by emitting initialization for all static members.
-
- Lastly, I noticed that CXX_FOR_TARGET was being ignored -- that's
- because the align-c++.exp testcase is compiling with the C compiler
- driver. Fixed by passing "c++" as option to prepare_for_testing.

- gdb/python: allow Frame.read_var to accept named arguments
- This commit allows Frame.read_var to accept named arguments, and also
- improves (I think) some of the error messages emitted when values of
- the wrong type are passed to this function.
-
- The read_var method takes two arguments, one a variable, which is
- either a gdb.Symbol or a string, while the second, optional, argument
- is always a gdb.Block.
-
- I'm now using 'O!' as the format specifier for the second argument,
- which allows the argument type to be checked early on. Currently, if
- the second argument is of the wrong type then we get this error:
-
- (gdb) python print(gdb.selected_frame().read_var("a1", "xxx"))
- Traceback (most recent call last):
- File "<string>", line 1, in <module>
- RuntimeError: Second argument must be block.
- Error while executing Python code.
- (gdb)
-
- After this commit, we now get an error like this:
-
- (gdb) python print(gdb.selected_frame().read_var("a1", "xxx"))
- Traceback (most recent call last):
- File "<string>", line 1, in <module>
- TypeError: argument 2 must be gdb.Block, not str
- Error while executing Python code.
- (gdb)
-
- Changes are:
-
- 1. Exception type is TypeError not RuntimeError, this is unfortunate
- as user code _could_ be relying on this, but I think the improvement
- is worth the risk, user code relying on the exact exception type is
- likely to be pretty rare,
-
- 2. New error message gives argument position and expected argument
- type, as well as the type that was passed.
-
- If the first argument, the variable, has the wrong type then the
- previous exception was already a TypeError, however, I've updated the
- text of the exception to more closely match the "standard" error
- message we see above. If the first argument has the wrong type then
- before this commit we saw this:
-
- (gdb) python print(gdb.selected_frame().read_var(123))
- Traceback (most recent call last):
- File "<string>", line 1, in <module>
- TypeError: Argument must be a symbol or string.
- Error while executing Python code.
- (gdb)
-
- And after we see this:
-
- (gdb) python print(gdb.selected_frame().read_var(123))
- Traceback (most recent call last):
- File "<string>", line 1, in <module>
- TypeError: argument 1 must be gdb.Symbol or str, not int
- Error while executing Python code.
- (gdb)
-
- For existing code that doesn't use named arguments and doesn't rely on
- exceptions, there will be no changes after this commit.

-
- For existing unwinder code that doesn't throw any exceptions nothing

- gdb: fix reg corruption from displaced stepping on amd64
- This commit aims to address a problem that exists with the current
- approach to displaced stepping, and was identified in PR gdb/22921.
-
- Displaced stepping is currently supported on AArch64, ARM, amd64,
- i386, rs6000 (ppc), and s390. Of these, I believe there is a problem
- with the current approach which will impact amd64 and ARM, and can
- lead to random register corruption when the inferior makes use of
- asynchronous signals and GDB is using displaced stepping.
-
- The problem can be found in displaced_step_buffers::finish in
- displaced-stepping.c, and is this; after GDB tries to perform a
- displaced step, and the inferior stops, GDB classifies the stop into
- one of two states, either the displaced step succeeded, or the
- displaced step failed.
-
- If the displaced step succeeded then gdbarch_displaced_step_fixup is
- called, which has the job of fixing up the state of the current
- inferior as if the step had not been performed in a displaced manner.
- This all seems just fine.
-
- However, if the displaced step is considered to have not completed
- then GDB doesn't call gdbarch_displaced_step_fixup, instead GDB
- remains in displaced_step_buffers::finish and just performs a minimal
- fixup which involves adjusting the program counter back to its
- original value.
-
- The problem here is that for amd64 and ARM setting up for a displaced
- step can involve changing the values in some temporary registers. If
- the displaced step succeeds then this is fine; after the step the
- temporary registers are restored to their original values in the
- architecture specific code.
-
- But if the displaced step does not succeed then the temporary
- registers are never restored, and they retain their modified values.
-
- In this context a temporary register is simply any register that is
- not otherwise used by the instruction being stepped that the
- architecture specific code considers safe to borrow for the lifetime
- of the instruction being stepped.
-
- In the bug PR gdb/22921, the amd64 instruction being stepped is
- an rip-relative instruction like this:
-
- jmp *0x2fe2(%rip)
-
- When we displaced step this instruction we borrow a register, and
- modify the instruction to something like:
-
- jmp *0x2fe2(%rcx)
-
- with %rcx having its value adjusted to contain the original %rip
- value.
-
- Now if the displaced step does not succeed, then %rcx will be left
- with a corrupted value. Obviously corrupting any register is bad; in
- the bug report this problem was spotted because %rcx is used as a
- function argument register.
-
- And finally, why might a displaced step not succeed? Asynchronous
- signals provides one reason. GDB sets up for the displaced step and,
- at that precise moment, the OS delivers a signal (SIGALRM in the bug
- report), the signal stops the inferior at the address of the displaced
- instruction. GDB cancels the displaced instruction, handles the
- signal, and then tries again with the displaced step. But it is that
- first cancellation of the displaced step that causes the problem; in
- that case GDB (correctly) sees the displaced step as having not
- completed, and so does not perform the architecture specific fixup,
- leaving the register corrupted.
-
- The reason why I think AArch64, rs600, i386, and s390 are not effected
- by this problem is that I don't believe these architectures make use
- of any temporary registers, so when a displaced step is not completed
- successfully, the minimal fix up is sufficient.
-
- On amd64 we use at most one temporary register.
-
- On ARM, looking at arm_displaced_step_copy_insn_closure, we could
- modify up to 16 temporary registers, and the instruction being
- displaced stepped could be expanded to multiple replacement
- instructions, which increases the chances of this bug triggering.
-
- This commit only aims to address the issue on amd64 for now, though I
- believe that the approach I'm proposing here might be applicable for
- ARM too.
-
- What I propose is that we always call gdbarch_displaced_step_fixup.
-
- We will now pass an extra argument to gdbarch_displaced_step_fixup,
- this a boolean that indicates whether GDB thinks the displaced step
- completed successfully or not.
-
- When this flag is false this indicates that the displaced step halted
- for some "other" reason. On ARM GDB can potentially read the
- inferior's program counter in order figure out how far through the
- sequence of replacement instructions we got, and from that GDB can
- figure out what fixup needs to be performed.
-
- On targets like amd64 the problem is slightly easier as displaced
- stepping only uses a single replacement instruction. If the displaced
- step didn't complete the GDB knows that the single instruction didn't
- execute.
-
- The point is that by always calling gdbarch_displaced_step_fixup, each
- architecture can now ensure that the inferior state is fixed up
- correctly in all cases, not just the success case.
-
- On amd64 this ensures that we always restore the temporary register
- value, and so bug PR gdb/22921 is resolved.
-
- In order to move all architectures to this new API, I have moved the
- minimal roll-back version of the code inside the architecture specific
- fixup functions for AArch64, rs600, s390, and ARM. For all of these
- except ARM I think this is good enough, as no temporaries are used all
- that's needed is the program counter restore anyway.
-
- For ARM the minimal code is no worse than what we had before, though I
- do consider this architecture's displaced-stepping broken.
-
- I've updated the gdb.arch/amd64-disp-step.exp test to cover the
- 'jmpq*' instruction that was causing problems in the original bug, and
- also added support for testing the displaced step in the presence of
- asynchronous signal delivery.
-
- I've also added two new tests (for amd64 and i386) that check that GDB
- can correctly handle displaced stepping over a single instruction that
- branches to itself. I added these tests after a first version of this
- patch relied too much on checking the program-counter value in order
- to see if the displaced instruction had executed. This works fine in
- almost all cases, but when an instruction branches to itself a pure
- program counter check is not sufficient. The new tests expose this
- problem.

- bfd+ld: when / whether to generate .c files
- Having been irritated by seeing bfd/elf{32,64}-aarch64.c to be re-
- generated in x86-only builds, I came across 769a27ade588 ("Re: bfd
- BLD-POTFILES.in dependencies"). I think this went slightly too far, as
- outside of maintainer mode dependencies will cause the subset of files
- to be (re-)generated which are actually needed for the build.
- Generating them all is only needed when wanting to update certain files
- under bfd/po/, i.e. in maintainer mode.
-
- In the course of looking around in an attempt to try to understand how
- things are meant to work, I further noticed that ld has got things
- slightly wrong too: BLD-POTFILES.in depending on $(BLD_POTFILES) isn't
- quite right (the output doesn't change when any of the enumerated files
- changes; it's the mere presence which matters); like in bfd it looks
- like we would better extend BUILT_SOURCES accordingly.
-
- Furthermore it became apparent that ld fails to enumerate the .c files
- generated from the .l and .y ones. While in their absence it was benign
- whether translatable strings in the source files were actually marked as
- such, this now becomes relevant. Mark respective strings at the same
- time, but skipping ones which look to be of interest for debugging
- purposes only (e.g. such used by printf() enclosed in #ifdef TRACE).

- Use bfd_alloc memory for read_debugging_info storage
- Trying to free malloc'd memory used by the stabs and coff debug info
- parsers is complicated, and traversing the trees generated requires a
- lot of code. It's better to bfd_alloc the memory which allows it all
- to be freed without fuss when the bfd is closed. In the process of
- doing this I reverted most of commit a6336913332.
-
- Some of the stabs handling code grows arrays of pointers with realloc,
- to deal with arbitrary numbers of fields, function args, etc. The
- code still does that but copies over to bfd_alloc memory when
- finished. The alternative is to parse twice, once to size, then again
- to populate the arrays. I think that complication is unwarranted.
-
- Note that there is a greater than zero chance this patch breaks
- something, eg. that I missed an attempt to free obj_alloc memory.
- Also it seems there are no tests in the binutils testsuite aimed at
- exercising objdump --debugging.

- gdb: cleanup around some set_momentary_breakpoint_at_pc calls
- I noticed a couple of places in infrun.c where we call
- set_momentary_breakpoint_at_pc, and then set the newly created
- breakpoint's thread field, these are in:
-
- insert_exception_resume_breakpoint
- insert_exception_resume_from_probe
-
- Function set_momentary_breakpoint_at_pc calls
- set_momentary_breakpoint, which always creates the breakpoint as
- thread-specific for the current inferior_thread().
-
- The two insert_* functions mentioned above take an arbitrary
- thread_info* as an argument and set the breakpoint::thread to hold the
- thread number of that arbitrary thread.
-
- However, the insert_* functions store the breakpoint pointer within
- the current inferior_thread(), so we know that the thread being passed
- in must be the currently selected thread.
-
- What this means is that we can:
-
- 1. Assert that the thread being passed in is the currently selected
- thread, and
-
- 2. No longer adjust the breakpoint::thread field, this will already
- have been set correctly be calling set_momentary_breakpoint_at_pc.
-
- There should be no user visible changes after this commit.

- gdb: don't always print breakpoint location after failed condition check
- Consider the following session:
-
- (gdb) list some_func
- 1 int
- 2 some_func ()
- 3 {
- 4 int *p = 0;
- 5 return *p;
- 6 }
- 7
- 8 void
- 9 foo ()
- 10 {
- (gdb) break foo if (some_func ())
- Breakpoint 1 at 0x40111e: file bpcond.c, line 11.
- (gdb) r
- Starting program: /tmp/bpcond
-
- Program received signal SIGSEGV, Segmentation fault.
- 0x0000000000401116 in some_func () at bpcond.c:5
- 5 return *p;
- Error in testing condition for breakpoint 1:
- The program being debugged stopped while in a function called from GDB.
- Evaluation of the expression containing the function
- (some_func) will be abandoned.
- When the function is done executing, GDB will silently stop.
-
- Breakpoint 1, 0x0000000000401116 in some_func () at bpcond.c:5
- 5 return *p;
- (gdb)
-
- What happens here is the breakpoint condition includes a call to an
- inferior function, and the inferior function segfaults. We can see
- that GDB reports the segfault, and then gives an error message that
- indicates that an inferior function call was interrupted.
-
- After this GDB appears to report that it is stopped at Breakpoint 1,
- inside some_func.
-
- I find this second stop report a little confusing. While it is true
- that GDB stopped as a result of hitting breakpoint 1, I think the
- message GDB currently prints might give the impression that GDB is
- actually stopped at a location of breakpoint 1, which is not the case.
-
- Also, I find the second stop message draws attention away from
- the "Program received signal SIGSEGV, Segmentation fault" stop
- message, and this second stop might be thought of as replacing in
- someway the earlier message.
-
- In short, I think things would be clearer if the second stop message
- were not reported at all, so the output should, I think, look like
- this:
-
- (gdb) list some_func
- 1 int
- 2 some_func ()
- 3 {
- 4 int *p = 0;
- 5 return *p;
- 6 }
- 7
- 8 void
- 9 foo ()
- 10 {
- (gdb) break foo if (some_func ())
- Breakpoint 1 at 0x40111e: file bpcond.c, line 11.
- (gdb) r
- Starting program: /tmp/bpcond
-
- Program received signal SIGSEGV, Segmentation fault.
- 0x0000000000401116 in some_func () at bpcond.c:5
- 5 return *p;
- Error in testing condition for breakpoint 1:
- The program being debugged stopped while in a function called from GDB.
- Evaluation of the expression containing the function
- (some_func) will be abandoned.
- When the function is done executing, GDB will silently stop.
- (gdb)
-
- The user can still find the number of the breakpoint that triggered
- the initial stop in this line:
-
- Error in testing condition for breakpoint 1:
-
- But there's now only one stop reason reported, the SIGSEGV, which I
- think is much clearer.
-
- To achieve this change I set the bpstat::print field when:
-
- (a) a breakpoint condition evaluation failed, and
-
- (b) the $pc of the thread changed during condition evaluation.
-
- I've updated the existing tests that checked the error message printed
- when a breakpoint condition evaluation failed.

- gdb: avoid repeated signal reporting during failed conditional breakpoint
- Consider the following case:

- 5 return *p;
- 6 }

- 5 return *p;
- Error in testing breakpoint condition:
- The program being debugged was signaled while in a function called from GDB.
- GDB remains in the frame where the signal was received.
- To change this behavior use "set unwindonsignal on".
- Evaluation of the expression containing the function
- (some_func) will be abandoned.
- When the function is done executing, GDB will silently stop.
-
- Program received signal SIGSEGV, Segmentation fault.
-
- Breakpoint 1, 0x0000000000401116 in some_func () at bpcond.c:5
- 5 return *p;
- (gdb)
-
- Notice that this line:
-
- Program received signal SIGSEGV, Segmentation fault.
-
- Appears twice in the output. The first time is followed by the
- current location. The second time is a little odd, why do we print
- that?
-
- Printing that line is controlled, in part, by a global variable,
- stopped_by_random_signal. This variable is reset to zero in
- handle_signal_stop, and is set if/when GDB figures out that the
- inferior stopped due to some random signal.
-
- The problem is, in our case, GDB first stops at the breakpoint for
- foo, and enters handle_signal_stop and the stopped_by_random_signal
- global is reset to 0.
-
- Later within handle_signal_stop GDB calls bpstat_stop_status, it is
- within this function (via bpstat_check_breakpoint_conditions) that the
- breakpoint condition is checked, and, we end up calling the inferior
- function (some_func in our example above).
-
- In our case above the thread performing the inferior function call
- segfaults in some_func. GDB catches the SIGSEGV and handles the stop,
- this causes us to reenter handle_signal_stop. The global variable
- stopped_by_random_signal is updated, this time it is set to true
- because the thread stopped due to SIGSEGV. As a result of this we
- print the first instance of the line (as seen above in the example).
-
- Finally we unwind GDB's call stack, the inferior function call is
- complete, and we return to the original handle_signal_stop. However,
- the stopped_by_random_signal global is still carrying the value as
- computed for the inferior function call's stop, which is why we now
- print a second instance of the line, as seen in the example.
-
- To prevent this, I propose adding a scoped_restore before we start an
- inferior function call. This will save and restore the global
- stopped_by_random_signal value.
-
- With this done, the output from our example is now this:
-
- (gdb) list some_func
- 1 int
- 2 some_func ()
- 3 {
- 4 int *p = 0;
- 5 return *p;
- 6 }
- 7
- 8 void
- 9 foo ()
- 10 {
- (gdb) break foo if (some_func ())
- Breakpoint 1 at 0x40111e: file bpcond.c, line 11.
- (gdb) r
- Starting program: /tmp/bpcond
-
- Program received signal SIGSEGV, Segmentation fault.
- 0x0000000000401116 in some_func () at bpcond.c:5
- 5 return *p;
- Error in testing condition for breakpoint 1:
- The program being debugged stopped while in a function called from GDB.
- Evaluation of the expression containing the function
- (some_func) will be abandoned.
- When the function is done executing, GDB will silently stop.
-
- Breakpoint 1, 0x0000000000401116 in some_func () at bpcond.c:5
- 5 return *p;
- (gdb)
-
- We now only see the 'Program received signal SIGSEGV, ...' line once,
- which I think makes more sense.
-
- Finally, I'm aware that the last few lines, that report the stop as
- being at 'Breakpoint 1', when this is not where the thread is actually
- located anymore, is not great. I'll address that in the next commit.

- gdbserver: allow agent expressions to fail with invalid memory access
- This commit extends gdbserver to take account of a failed memory
- access from agent_mem_read, and to return a new eval_result_type
- expr_eval_invalid_memory_access.
-
- I have only updated the agent_mem_read calls related directly to
- reading memory, I have not updated any of the calls related to
- tracepoint data collection. This is just because I'm not familiar
- with that area of gdb/gdbserver, and I don't want to break anything,
- so leaving the existing behaviour untouched seems like the safest
- approach.
-
- I've then updated gdb.base/bp-cond-failure.exp to test evaluating the
- breakpoints on the target, and have also extended the test so that it
- checks for different sizes of memory access.

-
- gdbserver: allows agent_mem_read to return an error code
- Currently the gdbserver function agent_mem_read ignores any errors
- from calling read_inferior_memory. This means that if there is an
- attempt to access invalid memory then this will appear to succeed.
-
- In this patch I update agent_mem_read so that if read_inferior_memory
- fails, agent_mem_read will return an error code.
-
- However, none of the callers of agent_mem_read actually check the
- return value, so this commit will have no effect on anything. In the
- next commit I will update the users of agent_mem_read to check for the
- error code.
-
- I've also updated the header comments on agent_mem_read to better
- reflect what the function does, and its possible return values.

- gdb: include breakpoint number in testing condition error message
- When GDB fails to test the condition of a conditional breakpoint, for
- whatever reason, the error message looks like this:
-
- (gdb) break foo if (*(int *) 0) == 1
- Breakpoint 1 at 0x40111e: file bpcond.c, line 11.
- (gdb) r
- Starting program: /tmp/bpcond
- Error in testing breakpoint condition:
- Cannot access memory at address 0x0
-
- Breakpoint 1, foo () at bpcond.c:11
- 11 int a = 32;
- (gdb)
-
- The line I'm interested in for this commit is this one:
-
- Error in testing breakpoint condition:
-
- In the case above we can figure out that the problematic breakpoint
- was #1 because in the final line of the message GDB reports the stop
- at breakpoint #1.
-
- However, in the next few patches I plan to change this. In some cases
- I don't think it makes sense for GDB to report the stop as being at
- breakpoint #1, consider this case:
-
- (gdb) list some_func
- 1 int
- 2 some_func ()
- 3 {
- 4 int *p = 0;
- 5 return *p;
- 6 }
- 7
- 8 void
- 9 foo ()
- 10 {
- (gdb) break foo if (some_func ())
- Breakpoint 1 at 0x40111e: file bpcond.c, line 11.
- (gdb) r
- Starting program: /tmp/bpcond
-
- Program received signal SIGSEGV, Segmentation fault.
- 0x0000000000401116 in some_func () at bpcond.c:5
- 5 return *p;
- Error in testing breakpoint condition:
- The program being debugged was signaled while in a function called from GDB.
- GDB remains in the frame where the signal was received.
- To change this behavior use "set unwindonsignal on".
- Evaluation of the expression containing the function
- (some_func) will be abandoned.
- When the function is done executing, GDB will silently stop.
-
- Program received signal SIGSEGV, Segmentation fault.
-
- Breakpoint 1, 0x0000000000401116 in some_func () at bpcond.c:5
- 5 return *p;
- (gdb)
-
- Notice that, the final lines of output reports the stop as being at
- breakpoint #1, even though the inferior in not located within
- some_func, and it's certainly not located at the breakpoint location.
-
- I find this behaviour confusing, and propose that this should be
- changed. However, if I make that change then every reference to
- breakpoint #1 will be lost from the error message.
-
- So, in this commit, in preparation for the later commits, I propose to
- change the 'Error in testing breakpoint condition:' line to this:
-
- Error in testing condition for breakpoint NUMBER:
-
- where NUMBER will be filled in as appropriate. Here's the first
- example with the updated error:
-
- (gdb) break foo if (*(int *) 0) == 0
- Breakpoint 1 at 0x40111e: file bpcond.c, line 11.
- (gdb) r
- Starting program: /tmp/bpcond
- Error in testing condition for breakpoint 1:
- Cannot access memory at address 0x0
-
- Breakpoint 1, foo () at bpcond.c:11
- 11 int a = 32;
- (gdb)
-
- The breakpoint number does now appear twice in the output, but I don't
- see that as a negative.
-
- This commit just changes the one line of the error, and updates the
- few tests that either included the old error in comments, or actually
- checked for the error in the expected output.
-
- As the only test that checked the line I modified is a Python test,
- I've added a new test that doesn't rely on Python that checks the
- error message in detail.
-
- While working on the new test, I spotted that it would fail when run
- with native-gdbserver and native-extended-gdbserver target boards.
- This turns out to be due to a gdbserver bug. To avoid cluttering this
- commit I've added a work around to the new test script so that the
- test passes for the remote boards, in the next few commits I will fix
- gdbserver, and update the test script to remove the work around.

- gdb/riscv: fix regressions in gdb.base/unwind-on-each-insn.exp
- This commit builds on the previous one to fix all the remaining
- failures in gdb.base/unwind-on-each-insn.exp for RISC-V.
-
- The problem we have in gdb.base/unwind-on-each-insn.exp is that, when
- we are in the function epilogue, the previous frame and stack pointer
- values are being restored, and so, the values that we calculated
- during the function prologue are no longer suitable.
-
- Here's an example from the function 'bar' in the mentioned test. This
- was compiled for 64-bit RISC-V with compressed instruction support:
-
- Dump of assembler code for function bar:
- 0x000000000001018a <+0>: add sp,sp,-32
- 0x000000000001018c <+2>: sd ra,24(sp)
- 0x000000000001018e <+4>: sd fp,16(sp)
- 0x0000000000010190 <+6>: add fp,sp,32
- 0x0000000000010192 <+8>: sd a0,-24(fp)
- 0x0000000000010196 <+12>: ld a0,-24(fp)
- 0x000000000001019a <+16>: jal 0x10178 <foo>
- 0x000000000001019e <+20>: nop
- 0x00000000000101a0 <+22>: ld ra,24(sp)
- 0x00000000000101a2 <+24>: ld fp,16(sp)
- 0x00000000000101a4 <+26>: add sp,sp,32
- 0x00000000000101a6 <+28>: ret
- End of assembler dump.
-
- When we are at address 0x101a4 the previous instruction has restored
- the frame-pointer, as such GDB's (current) preference for using the
- frame-pointer as the frame base address is clearly not going to work.
- We need to switch to using the stack-pointer instead.
-
- At address 0x101a6 the previous instruction has restored the
- stack-pointer value. Currently GDB will not understand this and so
- will still assume the stack has been decreased by 32 bytes in this
- function.
-
- My proposed solution is to extend GDB such that GDB will scan the
- instructions at the current $pc looking for this pattern:
-
- ld fp,16(sp)
- add sp,sp,32
- ret
-
- Obviously the immediates can change, but the basic pattern indicates
- that the function is in the process of restoring state before
- returning. If GDB sees this pattern then GDB can use the inferior's
- position within this instruction sequence to help calculate the
- correct frame-id.
-
- With this implemented then gdb.base/unwind-on-each-insn.exp now fully
- passes.
-
- Obviously what I've implemented is just a heuristic. It's not going
- to work for every function. If the compiler reorders the
- instructions, or merges the epilogue back into the function body then
- GDB is once again going to get the frame-id wrong.
-
- I'm OK with that, we're no worse off that we are right now in that
- situation (plus we can always improve the heuristic later).
-
- Remember, this is for debugging code without debug information,
- and (in our imagined situation) with more aggressive levels of
- optimisation being used. Obviously GDB is going to struggle in these
- situations.
-
- My thinking is, lets get something in place now. Then, later, if
- possible, we might be able to improve the logic to cover more
- situations -- if there's an interest in doing so. But I figure we
- need something in place as a starting point.
-
- After this commit gdb.base/unwind-on-each-insn.exp passes with no
- failures on RV64.

- gdb/riscv: support c.ldsp and c.lwsp in prologue scanner
- Add support to the RISC-V prologue scanner for c.ldsp and c.lwsp
- instructions.
-
- This fixes some of the failures in gdb.base/unwind-on-each-insn.exp,
- though there are further failures that are not fixed by this commit.
-
- This change started as a wider fix that would address all the failures
- in gdb.base/unwind-on-each-insn.exp, however, that wider fix needed
- support for the two additional compressed instructions.
-
- When I added support for those two compressed instructions I noticed
- that some of the failures in gdb.base/unwind-on-each-insn.exp resolved
- themselves!
-
- Here's what's going on:
-
- The reason for the failures is that GDB is trying to build the
- frame-id during the last few instructions of the function. These are
- the instructions that restore the frame and stack pointers just prior
- to the return instruction itself.
-
- By the time we reach the function epilogue the stack offset that we
- calculated during the prologue scan is no longer valid, and so we
- calculate the wrong frame-id.
-
- However, in the particular case of interest here, the test function
- 'foo', the function is so simple and short (the empty function) that
- GDB's prologue scan could, in theory, scan every instruction of the
- function.
-
- I say "could, in theory," because currently GDB stops the prologue
- scan early when it hits an unknown instruction. The unknown
- instruction happens to be one of the compressed instructions that I'm
- adding support for in this commit.
-
- Now that GDB understands the compressed instructions the prologue scan
- really does go from the start of the function right up to the current
- program counter. As such, GDB sees that the stack frame has been
- allocated, and then deallocated, and so builds the correct frame-id.
-
- Of course, most real functions are not as simple as the test function
- 'foo'. As such, we can't usually rely on scanning right up to the end
- of the function -- there are some instructions we always need to stop
- at because GDB can't reason about how they change the inferior
- state (e.g. a function call). The test function 'bar' is just such an
- example.
-
- After this commit, we can now build the frame-id correctly for every
- instruction in 'foo', but there are some tests still failing in 'bar'.

- printing scheme. This updates the following settings:
-
- set/show debug riscv breakpoints
- set/show debug riscv gdbarch
- set/show debug riscv infcall
- set/show debug riscv unwinder
-
- All of these settings now take a boolean rather than an integer, and
- all print their output using the new debug scheme.
-
- There should be no visible change for anyone not turning on debug.

- opcodes/arm: adjust whitespace in cpsie instruction
- While I was working on the disassembler styling for ARM I noticed that
- the whitespace in the cpsie instruction was inconsistent with most of
- the other ARM disassembly output, the disassembly for cpsie looks like
- this:
-
- cpsie if,#10
-
- notice there's no space before the '#10' immediate, most other ARM
- instructions have a space before each operand.
-
- This commit updates the disassembler to add the missing space, and
- updates the tests I found that tested this instruction.

-
- [gdb/testsuite] Fix gdb.server/server-kill.exp for remote target
-
- The first of these commits fixed an issue in GDB and tried to extend
- the gdb.server/server-kill.exp test to cover the GDB fix.
-
- Unfortunately, the changes to gdb.server/server-kill.exp were not
- correct, and were causing problems when trying to run with the
- remote-gdbserver-on-localhost board file.
-
- The second commit reverts some of the gdb.server/server-kill.exp
- changes introduced in the first commit so that the test will now work
- correctly with the remote-gdbserver-on-localhost board file.
-
- The second commit is just about GDB's testing infrastructure -- it's
- not about the original fix to GDB from the first commit, the actual
- GDB change was fine.
-
- While reviewing the second commit I wanted to check that the problem
- fixed in the first commit is still being tested by the
- gdb.server/server-kill.exp script, so I reverted the change to
- breakpoint.c that is the core of the first commit and ran the test
- script ..... and saw no failures.
-
- The first commit is about GDB discovering that gdbserver has died
- while trying to insert a breakpoint. As soon as GDB spots that
- gdbserver is gone we mourn the remote inferior, which ends up deleting
- all the breakpoints associated with the remote inferiors. We then
- throw an exception which is caught in the insert breakpoints code, and
- we try to display an error that includes the breakpoint number
- .... but the breakpoint has already been deleted ... and so GDB
- crashes.
-
- After digging a little, what I found is that today, when the test does
- 'stepi' the first thing we end up doing is calculating the frame-id as
- part of the stepi logic, it is during this frame-id calculation that
- we mourn the remote inferior, delete the breakpoints, and throw an
- exception. The exception is caught by the top level interpreter loop,
- and so we never try to print the breakpoint number which is what
- caused the original crash.
-
- If I add an 'info frame' command to the test script, prior to killing
- gdbserver, then now when we 'stepi' GDB already has the frame-id
- calculated, and the first thing we do is try to insert the
- breakpoints, this will trigger the original bug.
-
- In order to reproduce this experiment you'll need to change a function
- in breakpoint.c, like this:
-
- static void
- rethrow_on_target_close_error (const gdb_exception &e)
- {
- return;
- }
-
- Then run gdb.server/server-kill.exp with and without this patch. You
- should find that without this patch there are zero test failures,
- while with this patch there will be one failure like this:
-
- (gdb) PASS: gdb.server/server-kill.exp: test_stepi: info frame
- Executing on target: kill -9 4513 (timeout = 300)
- builtin_spawn -ignore SIGHUP kill -9 4513
- stepi
- ../../src/gdb/breakpoint.c:2863: internal-error: insert_bp_location: Assertion `bl->owner != nullptr' failed.
- A problem internal to GDB has been detected,
- further debugging may prove unreliable.

- gdb/testsuite: fix failure in gdb.python/py-unwind.exp
- A potential test failure was introduced with commit:
-
- commit 6bf5f25bb150c0fbcb125e3ee466ba8f9680310b

- gdb/python: make the gdb.unwinder.Unwinder class more robust
-
- In this commit a new test was added, however the expected output
- pattern varies depending on which Python version GDB is linked
- against.
-
- Older versions of Python result in output like this:
-
- (gdb) python global_test_unwinder.name = "foo"
- Traceback (most recent call last):
- File "<string>", line 1, in <module>
- AttributeError: can't set attribute
- Error while executing Python code.
- (gdb)
-
- While more recent versions of Python give a similar, but slightly more
- verbose error message, like this:
-
- (gdb) python global_test_unwinder.name = "foo"
- Traceback (most recent call last):
- File "<string>", line 1, in <module>
- AttributeError: can't set attribute 'name'
- Error while executing Python code.
- (gdb)
-
- The test was only accepting the first version of the output. This
- commit extends the test pattern so that either version will be
- accepted.

- [aarch64] tpidr2: Fix erroneous detection logic for TPIDR2
- The detection logic for TPIDR2 was implemented incorrectly. Originally
- the detection was supposed to be through a ptrace error code, but in reality,
- for backwards compatibility, the detection should be based on the size of
- the returned iovec.
-
- For instance, if a target supports both TPIDR and TPIDR2, ptrace will return a
- iovec size of 16. If a target only supports TPIDR and not TPIDR2, it will
- return a iovec size of 8, even if we asked for 16 bytes.
-
- This patch fixes this issue in code that is shared between gdb and gdbserver,
- therefore both gdb and gdbserver are fixed.

- gdb/arm: Fix backtrace for pthread_cond_timedwait
- GDB expected PC should point right after the SVC instruction when the
- syscall is active. But some active syscalls keep PC pointing to the SVC
- instruction itself.
-
- This leads to a broken backtrace like:
- Backtrace stopped: previous frame identical to this frame (corrupt stack?)
- #0 0xb6f8681c in pthread_cond_timedwait@@GLIBC_2.4 () from /lib/arm-linux-gnueabihf/libpthread.so.0
- #1 0xb6e21f80 in ?? ()
-
- The reason is that .ARM.exidx unwinder gives up if PC does not point
- right after the SVC (syscall) instruction. I did not investigate why but
- some syscalls will point PC to the SVC instruction itself. This happens
- for the "futex" syscall used by pthread_cond_timedwait.
-
- That normally does not matter as ARM prologue unwinder gets called
- instead of the .ARM.exidx one. Unfortunately some glibc calls have more
- complicated prologue where the GDB unwinder fails to properly determine
- the return address (that is in fact an orthogonal GDB bug). I expect it
- is due to the "vpush" there in this case but I did not investigate it more:
-
- Dump of assembler code for function pthread_cond_timedwait@@GLIBC_2.4:
- 0xb6f8757c <+0>: push {r4, r5, r6, r7, r8, r9, r10, r11, lr}
- 0xb6f87580 <+4>: mov r10, r2
- 0xb6f87584 <+8>: vpush {d8}

- RISC-V: Allocate "various" operand type
- This commit intends to move operands that require very special handling or
- operand types that are so minor (e.g. only useful on a few instructions)
- under "W". I also intend this "W" to be "temporary" operand storage until
- we can find good two character (or less) operand type.
-
- In this commit, prefetch offset operand "f" for 'Zicbop' extension is moved
- to "Wif" because of its special handling (and allocating single character
- "f" for this operand type seemed too much).
-
- Current expected allocation guideline is as follows:
-
- 1. 'W'
- 2. The most closely related single-letter extension in lowercase
- (strongly recommended but not mandatory)
- 3. Identify operand type
-
- The author currently plans to allocate following three-character operand
- types (for operands including instructions from unratified extensions).
-
- 1. "Wif" ('Zicbop': fetch offset)
- 2. "Wfv" (unratified 'Zfa': value operand from FLI.[HSDQ] instructions)
- 3. "Wfm" / "WfM"
- 'Zfh', 'F', 'D', 'Q': rounding modes "m" with special handling
- solely for widening conversion instructions.
-
- gas/ChangeLog:
-
- * config/tc-riscv.c (validate_riscv_insn, riscv_ip): Move from
- "f" to "Wif".

- x86: convert testcases to use .insn
- This can't be done for all insns currently encoded with .byte. For one
- outside of 64-bit mode unused (typically ignored) register encoding bits
- in VEX/XOP/EVEX prefixes can't be set to their non-default values, since
- the necessary registers cannot be specified (and some of these bits
- can't even be used outside of 64-bit mode). And then there are odd tests
- like the first one in bad-bcast.s: Its purpose is to illegaly set EVEX.b
- together with EVEX.W (which could be expressed; note though EVEX.W set
- is invalid on its own), but then it also clears EVEX.B and EVEX.R' plus
- it sets EVEX.vvvv to other than 0xf (rendering the test ambiguous,
- because that's another #UD reason).
-
- In {,x86-64-}disassem.s many bogus encodings exist - some with ModR/M
- byte but insufficient displacement bytes, some using SIB encoding with
- the SIB byte actually being the supposed immediate. Some of these could
- be expressed by .insn, but I don't want to introduce bogus examples.
- These will all need adjustment anyway once the disassembler is improved
- in the way it deals with unrecognized encodings.
-
- Generally generated code is meant to remain the same. {,x86-64-}nops.d
- are exceptions because insn prefixes are emitted in a different order.
- opcode{,-intel,-suffix}.d are also adjusted (along with an according
- correction to opcode.s) to cover an apparent typo in the original tests
- (xor when or was meant).
-
- Where necessary --divide is added as gas option, to allow for the use
- of the extension opcode functionality.
-
- Comments are being adjusted where obviously wrong/misleading.

- x86: handle immediate operands for .insn
- Since we have no insn suffix and it's also not realistic to infer
- immediate size from the size of other (typically register) operands
- (like optimize_imm() does), and since we also don't have a template
- telling us permitted size(s), a new syntax construct is introduced to
- allow size (and signedness) specification. In the absence of such, the
- size is inferred from significant bits (which obviously may yield
- inconsistent results at least for effectively negative values, depending
- on whether BFD64 is enabled), and only if supplied expressions can be
- evaluated at parsing time. Being explicit is generally recommended to
- users.
-
- Size specification is permitted at bit granularity, but of course the
- eventually emitted immediate values will be padded up to 8-, 16-, 32-,
- or 64-bit fields.

- anyway. Plus this way there's at least _some_ way to have those bits
- set.
-
- For now this will only allow operand-less insns to be encoded this way.

- PR gdb/30219: Clear sync_quit_force_run in quit_force
- PR 30219 shows an internal error due to a "Bad switch" in
- print_exception() in gdb/exceptions.c. The switch in question
- contains cases for RETURN_QUIT and RETURN_ERROR, but is missing a case
- for the recently added RETURN_FORCED_QUIT. This commit adds that case.
-
- Making the above change allows the errant test case to pass, but does
- not fix the underlying problem, which I'll describe shortly. Even
- though the addition of a case for RETURN_FORCED_QUIT isn't the actual
- fix, I still think it's important to add this case so that other
- situations which lead to print_exeption() being called won't generate
- that "Bad switch" internal error.
-
- In order to understand the underlying problem, please examine
- this portion of the backtrace from the bug report:
-
- 0x5576e4ff5780 print_exception
- /home/smarchi/src/binutils-gdb/gdb/exceptions.c:100
- 0x5576e4ff5930 exception_print(ui_file*, gdb_exception const&)
- /home/smarchi/src/binutils-gdb/gdb/exceptions.c:110
- 0x5576e6a896dd quit_force(int*, int)
- /home/smarchi/src/binutils-gdb/gdb/top.c:1849
-
- The real problem is in quit_force; here's the try/catch which
- eventually leads to the internal error:
-
- /* Get out of tfind mode, and kill or detach all inferiors. */
- try
- {
- disconnect_tracing ();
- for (inferior *inf : all_inferiors ())
- kill_or_detach (inf, from_tty);
- }
- catch (const gdb_exception &ex)
- {
- exception_print (gdb_stderr, ex);
- }
-
- While running the calls in the try-block, a QUIT check is being
- performed. This check finds that sync_quit_force_run is (still) set,
- causing a gdb_exception_forced_quit to be thrown. The exception
- gdb_exception_forced_quit is derived from gdb_exception, causing
- exception_print to be called. As shown by the backtrace,
- print_exception is then called, leading to the internal error.
-
- The actual fix, also implemented by this commit, is to clear
- sync_quit_force_run along with the quit flag. This will allow the
- various cleanup code, called by quit_force, to run without triggering
- a gdb_exception_forced_quit. (Though, if another SIGTERM is sent to
- the gdb process, these flags will be set again and a QUIT check in the
- cleanup code will detect it and throw the exception.)

- aarch64: Add the SME2 ADD and SUB instructions
- Add support for the SME2 ADD. SUB, FADD and FSUB instructions.
- SUB and FSUB have the same form as ADD and FADD, except that

-
- The 64-bit ADD/SUB instructions require FEAT_SME_I16I64 and the
- 64-bit FADD/FSUB instructions require FEAT_SME_F64F64.
-
- These are the first instructions to have tied register list
- operands, as opposed to tied single registers.
-
- The parse_operands change prevents unsuffixed Z registers (width==-1)
- from being treated as though they had an Advanced SIMD-style suffix
- (.4s etc.). It means that:
-
- Error: expected element type rather than vector type at operand 2 -- `add za\.s\[w8,0\],{z0-z1}'
-
- becomes:
-
- Error: missing type suffix at operand 2 -- `add za\.s\[w8,0\],{z0-z1}'

-
- aarch64: Add the SME2 predicate-related instructions
- Implementation-wise, the main things to note here are:
-
- - the WHILE* instructions have forms that return a pair of predicate
- registers. This is the first time that we've had lists of predicate
- registers, and they wrap around after register 15 rather than after
- register 31.
-
- - the predicate-as-counter WHILE* instructions have a fourth operand
- that specifies the vector length. We can treat this as an enumeration,
- except that immediate values aren't allowed.
-
- - PEXT takes an unsuffixed predicate index of the form PN<n>[<imm>].
- This is the first instance of a vector/predicate index having
- no suffix.

-
- aarch64: Add the SME2 multivector LD1 and ST1 instructions
- SME2 adds LD1 and ST1 variants for lists of 2 and 4 registers.
- The registers can be consecutive or strided. In the strided case,
- 2-register lists have a stride of 8, starting at register x0xxx.
- 4-register lists have a stride of 4, starting at register x00xx.
-
- The instructions are predicated on a predicate-as-counter register in
- the range pn8-pn15. Although we already had register fields with upper
- bounds of 7 and 15, this is the first plain register operand to have a
- nonzero lower bound. The patch uses the operand-specific data field
- to record the minimum value, rather than having separate inserters
- and extractors for each lower bound. This in turn required adding
- an extra bit to the field.

-2023-03-30 Richard Sandiford <richard.sandiford@arm.com>
-
- aarch64: Add the SME2 MOVA instructions
- SME2 defines new MOVA instructions for moving multiple registers
- to and from ZA. As with SME, the instructions are also available
- through MOV aliases.
-
- One notable feature of these instructions (and many other SME2
- instructions) is that some register lists must start at a multiple
- of the list's size. The patch uses the general error "start register
- out of range" when this constraint isn't met, rather than an error
- specifically about multiples. This ensures that the error is
- consistent between these simple consecutive lists and later
- strided lists, for which the requirements aren't a simple multiple.

-2023-03-30 Richard Sandiford <richard.sandiford@arm.com>
-
- aarch64: Add support for predicate-as-counter registers
- SME2 adds a new format for the existing SVE predicate registers:
- predicates as counters rather than predicates as masks. In assembly
- code, operands that interpret predicates as counters are written
- pn<N> rather than p<N>.
-
- This patch adds support for these registers and extends some
- existing instructions to support them. Since the new forms
- are just a programmer convenience, there's no need to make them
- more restrictive than the earlier predicate-as-mask forms.

-
- aarch64; Add support for vector offset ranges
- Some SME2 instructions operate on a range of consecutive ZA vectors.
- This is indicated by syntax such as:
-
- za[<Wv>, <imml>:<immh>]
-
- Like with the earlier vgx2 and vgx4 support, we get better error
- messages if the parser allows all ZA indices to have a range.
- We can then reject invalid cases during constraint checking.
-
-2023-03-30 Richard Sandiford <richard.sandiford@arm.com>
-
- aarch64: Add support for vgx2 and vgx4
- Many SME2 instructions operate on groups of 2 or 4 ZA vectors.
- This is indicated by adding a "vgx2" or "vgx4" group size to the
- ZA index. The group size is optional in assembly but preferred
- for disassembly.
-
- There is not a binary distinction between mnemonics that have
- group sizes and mnemonics that don't, nor between mnemonics that
- take vgx2 and mnemonics that take vgx4. We therefore get better
- error messages if we allow any ZA index to have a group size
- during parsing, and wait until constraint checking to reject
- invalid sizes.
-
- A quirk of the way errors are reported means that if an instruction
- is wrong both in its qualifiers and its use of a group size, we'll
- print suggested alternative instructions that also have an incorrect
- group size. But that's a general property that also applies to
- things like out-of-range immediates. It's also not obviously the
- wrong thing to do. We need to be relatively confident that we're
- looking at the right opcode before reporting detailed operand-specific
- errors, so doing qualifier checking first seems resonable.

-
- aarch64: Prefer register ranges & support wrapping
- Until now, binutils has supported register ranges such
- as { v0.4s - v3.4s } as an unofficial shorthand for
- { v0.4s, v1.4s, v2.4s, v3.4s }. The SME2 ISA embraces this form
- and makes it the preferred disassembly. It also embraces wrapped
- lists such as { z31.s - z2.s }, which is something that binutils
- didn't previously allow.
-
- The range form was already binutils's preferred disassembly for 3- and
- 4-register lists. This patch prefers it for 2-register lists too.
- The patch also adds support for wrap-around.
-
-2023-03-30 Richard Sandiford <richard.sandiford@arm.com>
-
- aarch64: Add support for strided register lists
- SME2 has instructions that accept strided register lists,
- such as { z0.s, z4.s, z8.s, z12.s }. The purpose of this
- patch is to extend binutils to support such lists.
-
- The parsing code already had (unused) support for strides of 2.
- The idea here is instead to accept all strides during parsing
- and reject invalid strides during constraint checking.
-
- The SME2 instructions that accept strided operands also have
- non-strided forms. The errors about invalid strides therefore
- take a bitmask of acceptable strides, which allows multiple
- possibilities to be summed up in a single message.
-
- I've tried to update all code that handles register lists.

- aarch64: Sort fields alphanumerically
- This patch just sorts the field enum alphanumerically, which makes
- it easier to see if a particular field has already been defined.
-
- aarch64: Resync field names
- This patch just makes the comments in aarch64-opc.c:fields match

-2023-03-30 Richard Sandiford <richard.sandiford@arm.com>
-
- aarch64: Regularise FLD_* suffixes
- Some FLD_imm* suffixes used a counting scheme such as FLD_immN,
- FLD_immN_2, FLD_immN_3, etc., while others used the lsb as the
- suffix. The latter seems more mnemonic, and was a big help
- in doing the SME2 work.
-
- Similarly, the _10 suffix on FLD_SME_size_10 was nonobvious.
- Presumably it indicated a 2-bit field, but it actually starts
- in bit 22.
-
-2023-03-30 Richard Sandiford <richard.sandiford@arm.com>
-
- aarch64: Rename some of GAS's REG_TYPE_* macros
- In GAS, the vector and predicate registers are identified by
- REG_TYPE_VN, REG_TYPE_ZN and REG_TYPE_PN. This "N" is obviously
- a placeholder for the register number. However, we don't use that
- convention for integer and FP registers, and (more importantly)
- SME2 adds "predicate-as-counter" registers that are denoted PN.
-
- This patch therefore drops the "N" suffix from the existing
- registers. The main hitch is that Z was also used for the
- zero register in things like R_Z, but using ZR seems more
- consistent with the SP-based names.
-
-2023-03-30 Richard Sandiford <richard.sandiford@arm.com>
-
- aarch64: Add a aarch64_cpu_supports_inst_p helper
- Quite a lot of SME2 instructions have an opcode bit that selects
- between 32-bit and 64-bit forms of an instruction, with the 32-bit
- forms being part of base SME2 and with the 64-bit forms being part
- of an optional extension. It's nevertheless useful to have a single
- opcode entry for both forms since (a) that matches the ISA definition
- and (b) it tends to improve error reporting.
-
- This patch therefore adds a libopcodes function called
- aarch64_cpu_supports_inst_p that tests whether the target
- supports a particular instruction. In future it will depend
- on internal libopcodes routines.
-

- aarch64: Reorder some OP_SVE_* macros
- This patch just moves some out-of-order-looking OP_SVE_* macros.
-
- aarch64: Rename aarch64-tbl.h OP_SME_* macros
- This patch renames the OP_SME_* macros in aarch64-tbl.h so that
- they follow the same scheme as the OP_SVE_* ones. It also uses
- OP_SVE_ as the prefix, since there is no real distinction between
- the SVE and SME uses of qualifiers: a macro defined for one can
- be useful for the other too.
-
-2023-03-30 Richard Sandiford <richard.sandiford@arm.com>
-
- aarch64: Tweak priorities of parsing-related errors
- There are three main kinds of error reported during parsing,
- in increasing order of priority:
-
- - AARCH64_OPDE_RECOVERABLE (register seen instead of immediate)
- - AARCH64_OPDE_SYNTAX_ERROR
- - AARCH64_OPDE_FATAL_SYNTAX_ERROR
-
- This priority makes sense when comparing errors reported against the
- same operand. But if we get to operand 3 (say) and see a register
- instead of an immediate, that's likely to be a better match than
- something that fails with a syntax error at operand 1.
-
- The idea of this patch is to prioritise parsing-related errors
- based on operand index first, then by error code. Post-parsing
- errors still win over parsing errors, and their relative priorities
- don't change.
-
-2023-03-30 Richard Sandiford <richard.sandiford@arm.com>
-
- aarch64: Try to report invalid variants against the closest match
- If an instruction has invalid qualifiers, GAS would report the
- error against the final opcode entry that got to the qualifier-
- checking stage. It seems better to report the error against
- the opcode entry that had the closest match, just like we
- pick the closest match within an opcode entry for the
- "did you mean this?" message.
-
- This patch adds the number of invalid operands as an
- argument to AARCH64_OPDE_INVALID_VARIANT and then picks the
- AARCH64_OPDE_INVALID_VARIANT with the lowest argument.
-
-2023-03-30 Richard Sandiford <richard.sandiford@arm.com>
-
- aarch64: Tweak register list errors
- The error for invalid register lists had the form:
-
- invalid number of registers in the list; N registers are expected at operand M -- `insn'
-
- This seems a bit verbose. Also, the "bracketing" is really:
-
- (invalid number of registers in the list; N registers are expected) at operand M
-
- but the semicolon works against that.
-
- This patch goes for slightly shorter messages, setting a template
- that later patches can use for more complex cases.
-
-2023-03-30 Richard Sandiford <richard.sandiford@arm.com>
-
- aarch64: Make AARCH64_OPDE_REG_LIST take a bitfield
- AARCH64_OPDE_REG_LIST took a single operand that specified the
- expected number of registers. However, there are quite a few
- SME2 instructions that have both 2-register forms and (separate)
- 4-register forms. If the user tries to use a 3-register list,
- it isn't obvious which opcode entry they meant. Saying that we
- expect 2 registers and saying that we expect 4 registers would
- both be wrong.
-
- This patch therefore switches the operand to a bitfield. If a
- AARCH64_OPDE_REG_LIST is reported against multiple opcode entries,
- the patch ORs up the expected lengths.
-
- This has no user-visible effect yet. A later patch adds more error
- strings, alongside tests that use them.
-
-2023-03-30 Richard Sandiford <richard.sandiford@arm.com>
-
- aarch64: Add an operand class for SVE register lists
- SVE register lists were classified as SVE_REG, since there had been
- no particular reason to separate them out. However, some SME2
- instructions have tied register list operands, and so we need to
- distinguish registers and register lists when checking whether two
- operands match.
-
- Also, the register list operands used a general error message,
- even though we already have a dedicated error code for register
- lists that are the wrong length.

-
- aarch64: Commonise checks for index operands
- This patch splits out the constraint checking for index operands,
- so that it can be reused by new SME2 operands.
-
- aarch64: Add an error code for out-of-range registers
- libopcodes currently reports out-of-range registers as a general
- AARCH64_OPDE_OTHER_ERROR. However, this means that each register
- range needs its own hard-coded string, which is a bit cumbersome
- if the range is determined programmatically. This patch therefore
- adds a dedicated error type for out-of-range errors.
-
-2023-03-30 Richard Sandiford <richard.sandiford@arm.com>
-
- aarch64: Deprioritise AARCH64_OPDE_REG_LIST
- SME2 has many instructions that take a list of SVE registers.
- There are often multiple forms, with different forms taking
- different numbers of registers.
-
- This means that if, after a successful parse and qualifier match,
- we find that the number of registers does not match the opcode entry,
- the associated error should have a lower priority/severity than other
- errors reported at the same stage. For example, if there are 2-register
- and 4-register forms of an instruction, and if the assembly code uses
- the 2-register form with an out-of-range value, the out-of-range value
- error against the 2-register instruction should have a higher priority
- than the "wrong number of registers" error against the 4-register
- instruction.
-
- This is tested by the main SME2 patches, but seemed worth splitting out.

-2023-03-30 Richard Sandiford <richard.sandiford@arm.com>
-
- aarch64: Rework reporting of failed register checks
- There are many opcode table entries that share the same mnemonic.
- Trying to parse an invalid assembly line will trigger an error for
- each of these entries, but the specific error might vary from one
- entry to another, depending on the exact nature of the problem.
-
- GAS has quite an elaborate system for picking the most appropriate
- error out of all the failed matches. And in many cases it works well.
- However, one of the limitations is that the error is always reported
- against a single opcode table entry. If that table entry isn't the
- one that the user intended to use, then the error can end up being
- overly specific.
-
- This is particularly true if an instruction has a typoed register
- name, or uses a type of register that is not accepted by any
- opcode table entry. For example, one of the expected error
- matches for an attempted SVE2 instruction is:
-
- Error: operand 1 must be a SIMD scalar register -- `addp z32\.s,p0/m,z32\.s,z0\.s'
-
- even though the hypothetical user was presumably attempting to use
- the SVE form of ADDP rather than the Advanced SIMD one. There are
- many other instances of this in the testsuite.
-
- The problem becomes especially acute with SME2, since many SME2
- instructions reuse existing mnemonics. This could lead to us
- reporting an SME-related error against a non-SME instruction,
- or a non-SME-related error against an SME instruction.
-
- This patch tries to improve things by collecting together all
- the register types that an opcode table entry expected for a
- given operand. It also records what kind of register was
- actually seen, if any. It then tries to summarise all this
- in a more directed way, falling back to a generic error if
- the combination defies a neat summary.
-
- The patch includes tests for all new messages except REG_TYPE_ZA,
- which only triggers with SME2.
-
- To test this, I created an assembly file that contained the cross
- product of all known mnemonics and one example from each register
- class. I then looked for cases where the new routines fell back on the
- generic errors ("expected a register" or "unexpected register type").
- I locally added dummy messages for each one until there were no
- more hits. The patch adds a specimen instruction to diagnostics.s
- for each of these combinations. In each case, the combination didn't
- seem like something that could be summarised in a natural way, so the
- generic messages seemed better. There's always going to be an element
- of personal taste around this kind of thing though.
-
- Adding more register types made 1<<REG_TYPE_MAX exceed the range
- of the type, but we don't actually need/want 1<<REG_TYPE_MAX.

- aarch64: Try to avoid inappropriate default errors
- After parsing a '{' and the first register, parse_typed_reg would
- report errors in subsequent registers in the same way as for the
- first register. It used set_default_error, which reports errors
- of the form "operand N must be X".
-
- The problem is that if there are multiple opcode entries for the
- same mnemonic, there could be several matches that lead to a
- default error. There's no guarantee that the default error for
- the register list is the one that will be chosen.
-
- To take an example from the testsuite:
-
- ext z0.b,{z31.b,z32.b},#0
-
- gave:
-
- operand 2 must be an SVE vector register
-
- with the error being reported against the single-vector version
- of ext, even though the operand is clearly a list.
-
- This patch uses set_fatal_syntax_error to bump the priority of the
- error once we're sure that the operand is a list of the right type.

-
- aarch64: Improve errors for malformed register lists
- parse_typed_reg is used for parsing both bare registers and
- registers that occur in lists. If it doesn't see a register,
- or sees an unexpected kind of register, it queues a default
- error to report the problem. These default errors have the form
- "operand N must be an X", where X comes from the operand table.
-
- If there are multiple opcode entries that report default errors,
- GAS tries to pick the most appropriate one, using the opcode
- table order as a tiebreaker. But this can lead to cases where
- a syntax error in a register list is reported against an opcode
- that doesn't accept register lists. For example, the unlikely
- error:
-
- ext z0.b,{,},#0
-
- is reported as:
-
- operand 2 must be an SVE vector register -- `ext z0.b,{,},#0'
-
- even though operand 2 can be a register list.
-
- If we've parsed the opening '{' of a register list, and then see
- something that isn't remotely register-like, it seems better to
- report that directly as a syntax error, rather than rely on the
- default error. The operand won't be a valid list of anything,
- so there's no need to pick a specific Y in "operand N must be
- a list of Y".

- aarch64: Tweak parsing of integer & FP registers
- Integer registers were parsed indirectly through
- aarch64_reg_parse_32_64 (and thus aarch64_addr_reg_parse) rather
- than directly through parse_reg. This was because we need the
- qualifier associated with the register, and the logic to calculate

- However, SME2 adds instructions for which the range is
- w8-w11 instead.
-
- This patch therefore moves the range check from the parsing
- stage to the constraint-checking stage.
-
- Also, the previous error used a capitalised range W12-W15,
- whereas other register range errors used lowercase ranges
- like p0-p7. A quick internal poll showed a preference for
- the lowercase form, so the patch uses that.

-
- aarch64: Consolidate ZA slice parsing
- Now that parse_typed_reg checks the range of tile register numbers
- and libopcodes checks the range of vector select offsets, there's
- very little difference between the parsing of ZA tile indices,
- ZA array indices, and PSEL indices. The main one is that ZA
- array indices don't currently allow "za" to be qualified,
- but we need to remove that restriction for SME2.
-
- This patch therefore consolidates all three parsers into a single
- routine, parameterised by the type of register that they expect.

-
- aarch64: Move ZA range checks to aarch64-opc.c
- This patch moves the range checks on ZA vector select offsets from
- gas to libopcodes. Doing the checks there means that the error
- messages contain the expected range. It also fits in better
- with the error severity scheme, which becomes important later.
- (This is because out-of-range indices are treated as more severe than
- syntax errors, on the basis that parsing must have succeeded if we get
- to the point of checking the completed opcode.)
-
- The patch also adds a new check_za_access function for checking
- ZA accesses. That's a bit over the top for one offset check, but the
- function becomes more complex with later patches.
-
- sme-9-illegal.s checked for an invalid .q suffix using:
-
- psel p1, p15, p3.q[w15]
-
- but this is doubly invalid because it misses the immediate part
- of the index. The patch keeps that test but adds another with
- a zero index, so that .q is the only thing wrong.

- aarch64: Pass aarch64_indexed_za to parsers
- ZA indices have more parts than most operands, so passing these
- parts around individually is more awkward than for other operand

- further pieces: an offset range and a vector group size.
-
- This patch therefore replaces arguments for the individual pieces
- with a single argument for the index as a whole.

-
- aarch64: Make indexed_za use 64-bit immediates
- A later patch moves the range checking for ZA vector select

-
- aarch64: Rename za_tile_vector to za_index
- za_tile_vector is also used for indexing ZA as a whole, rather than
- just for indexing tiles. The former is more common than the latter

-
- The patch also names the associated structure, so that later patches
- can reuse it during parsing.

-
- aarch64: Treat ZA as a register
- We already treat the ZA tiles ZA0-ZA15 as registers. This patch
- does the same for ZA itself. parse_sme_zero_mask can then parse
- ZA tiles and ZA in the same way, through parsed_type_reg.
-
- One important effect of going through parsed_type_reg (in general)
- is that it allows ZA to take qualifiers. This is necessary for many
- SME2 instructions.
-
- However, to support existing unqualified uses of ZA, parse_reg_with_qual
- needs to treat the qualiier as optional. Hopefully the net effect is
- to give better error messages, since now that SME2 makes "za.<T>"
- valid in some contexts, it might be natural to use it (incorrectly)
- in ZERO too.
-
- While there, the patch also tweaks the error messages for invalid
- ZA tiles, to try to make some cases more specific.
-
- For now, parse_sme_za_array just uses parse_reg, rather than
- parse_typed_reg/parse_reg_with_qual. A later patch consolidates
- the parsing further.

-
- aarch64: Reuse parse_typed_reg for ZA tiles

-
- The patch also replaces the boolean in_reg_list parameter with

- aarch64: Fix SVE2 register/immediate distinction
- GAS refuses to interpret register names like x0 as unadorned

-
- For compatibility reasons, we can't extend the set of registers
- that GAS rejects for existing instructions. For example:
-
- mov x0, z0
-
- was valid code before SVE was added, so it needs to stay valid
- code even when SVE is enabled. But we can make GAS reject newer
- registers in newer instructions. The SVE instruction:
-
- and z0.s, z0.s, z0.h
-
- is therefore invalid, rather than z0.h being an immediate.
-
- This patch extends the SVE behaviour to SVE2. The old call
- to AARCH64_CPU_HAS_FEATURE was technically the wrong way around,
- although it didn't matter in practice for base SVE instructions
- since their avariants only set SVE.

- gdb/python: Allow gdb.UnwindInfo to be created with non gdb.Value args
- Currently when creating a gdb.UnwindInfo object a user must call
- gdb.PendingFrame.create_unwind_info and pass a frame-id object.
-
- The frame-id object should have at least a 'sp' attribute, and
- probably a 'pc' attribute too (it can also, in some cases have a
- 'special' attribute).
-
- Currently all of these frame-id attributes need to be gdb.Value
- objects, but the only reason for that requirement is that we have some
- code in py-unwind.c that only handles gdb.Value objects.
-
- If instead we switch to using get_addr_from_python in py-utils.c then
- we will support both gdb.Value objects and also raw numbers, which
- might make things simpler in some cases.
-
- So, I started rewriting pyuw_object_attribute_to_pointer (in
- py-unwind.c) to use get_addr_from_python. However, while looking at
- the code I noticed a problem.
-
- The pyuw_object_attribute_to_pointer function returns a boolean flag,
- if everything goes OK we return true, but we return false in two
- cases, (1) when the attribute is not present, which might be
- acceptable, or might be an error, and (2) when we get an error trying
- to extract the attribute value, in which case a Python error will have
- been set.
-
- Now in pending_framepy_create_unwind_info we have this code:
-
- if (!pyuw_object_attribute_to_pointer (pyo_frame_id, "sp", &sp))
- {
- PyErr_SetString (PyExc_ValueError,
- _("frame_id should have 'sp' attribute."));
- return NULL;
- }
-
- Notice how we always set an error. This will override any error that
- is already set.
-
- So, if you create a frame-id object that has an 'sp' attribute, but
- the attribute is not a gdb.Value, then currently we fail to extract
- the attribute value (it's not a gdb.Value) and set this error in
- pyuw_object_attribute_to_pointer:
-
- rc = pyuw_value_obj_to_pointer (pyo_value.get (), addr);
- if (!rc)
- PyErr_Format (
- PyExc_ValueError,
- _("The value of the '%s' attribute is not a pointer."),
- attr_name);
-
- Then we return to pending_framepy_create_unwind_info and immediately
- override this error with the error about 'sp' being missing.
-
- This all feels very confused.
-
- Here's my proposed solution: pyuw_object_attribute_to_pointer will now
- return a tri-state enum, with states OK, MISSING, or ERROR. The
- meanings of these states are:
-
- OK - Attribute exists and was extracted fine,
-
- MISSING - Attribute doesn't exist, no Python error was set.
-
- ERROR - Attribute does exist, but there was an error while
- extracting it, a Python error was set.
-
- We need to update pending_framepy_create_unwind_info, the only user of
- pyuw_object_attribute_to_pointer, but now I think things are much
- clearer. Errors from lower levels are not blindly overridden with the
- generic meaningless error message, but we still get the "missing 'sp'
- attribute" error when appropriate.
-
- This change also includes the switch to get_addr_from_python which was
- what started this whole journey.
-
- For well behaving user code there should be no visible changes after
- this commit.
-
- For user code that hits an error, hopefully the new errors should be
- more helpful in figuring out what's gone wrong.
-
- Additionally, users can now use integers for the 'sp' and 'pc'
- attributes in their frame-id objects if that is useful.

- gdb/python: add some additional methods to gdb.PendingFrame
- The gdb.Frame class has far more methods than gdb.PendingFrame. Given
- that a PendingFrame hasn't yet been claimed by an unwinder, there is a
- limit to which methods we can add to it, but many of the methods that
- the Frame class has, the PendingFrame class could also support.
-
- In this commit I've added those methods to PendingFrame that I believe
- are safe.
-
- In terms of implementation: if I was starting from scratch then I
- would implement many of these (or most of these) as attributes rather
- than methods. However, given both Frame and PendingFrame are just
- different representation of a frame, I think there is value in keeping
- the interface for the two classes the same. For this reason
- everything here is a method -- that's what the Frame class does.
-
- The new methods I've added are:
-
- - gdb.PendingFrame.is_valid: Return True if the pending frame
- object is valid.
-
- - gdb.PendingFrame.name: Return the name for the frame's function,
- or None.
-
- - gdb.PendingFrame.pc: Return the $pc register value for this
- frame.
-
- - gdb.PendingFrame.language: Return a string containing the
- language for this frame, or None.
-
- - gdb.PendingFrame.find_sal: Return a gdb.Symtab_and_line object
- for the current location within the pending frame, or None.
-
- - gdb.PendingFrame.block: Return a gdb.Block for the current
- pending frame, or None.
-
- - gdb.PendingFrame.function: Return a gdb.Symbol for the current
- pending frame, or None.
-
- In every case I've just copied the implementation over from gdb.Frame
- and cleaned the code slightly e.g. NULL to nullptr. Additionally each
- function required a small update to reflect the PendingFrame type, but
- that's pretty minor.
-
- There are tests for all the new methods.
-
- For more extensive testing, I added the following code to the file
- gdb/python/lib/command/unwinders.py:
-
- from gdb.unwinder import Unwinder
-
- class TestUnwinder(Unwinder):
- def __init__(self):
- super().__init__("XXX_TestUnwinder_XXX")
-
- def __call__(self,pending_frame):
- lang = pending_frame.language()
- try:
- block = pending_frame.block()
- assert isinstance(block, gdb.Block)
- except RuntimeError as rte:
- assert str(rte) == "Cannot locate block for frame."
- function = pending_frame.function()
- arch = pending_frame.architecture()
- assert arch is None or isinstance(arch, gdb.Architecture)
- name = pending_frame.name()
- assert name is None or isinstance(name, str)
- valid = pending_frame.is_valid()
- pc = pending_frame.pc()
- sal = pending_frame.find_sal()
- assert sal is None or isinstance(sal, gdb.Symtab_and_line)
- return None
-
- gdb.unwinder.register_unwinder(None, TestUnwinder())
-
- This registers a global unwinder that calls each of the new
- PendingFrame methods and checks the result is of an acceptable type.
- The unwinder never claims any frames though, so shouldn't change how
- GDB actually behaves.
-
- I then ran the testsuite. There was only a single regression, a test
- that uses 'disable unwinder' and expects a single unwinder to be
- disabled -- the extra unwinder is now disabled too, which changes the
- test output. So I'm reasonably confident that the new methods are not
- going to crash GDB.

-
- In pyuw_sniffer where the pending frames are created, we make use of a
- scoped_restore to invalidate the pending frame objects. However, this
- only restores the pending_frame_object::frame_info field to its
- previous value -- and it turns out we never actually give this field
- an initial value, it's left undefined.
-
- So, when the scoped_restore (called invalidate_frame) performs its
- cleanup, it actually restores the frame_info field to an undefined
- value. If this undefined value is not nullptr then any future
- accesses to the PendingFrame object result in undefined behaviour and
- most likely, a crash.
-
- As part of this commit I now initialize the frame_info field, which
- ensures all the new tests now pass.

- gdb/python: make the gdb.unwinder.Unwinder class more robust
- This commit makes a few related changes to the gdb.unwinder.Unwinder
- class attributes:
-
- 1. The 'name' attribute is now a read-only attribute. This prevents
- user code from changing the name after registering the unwinder. It
- seems very unlikely that any user is actually trying to do this in
- the wild, so I'm not very worried that this will upset anyone,
-
- 2. We now validate that the name is a string in the
- Unwinder.__init__ method, and throw an error if this is not the
- case. Hopefully nobody was doing this in the wild. This should
- make it easier to ensure the 'info unwinder' command shows sane
- output (how to display a non-string name for an unwinder?),
-
- 3. The 'enabled' attribute is now implemented with a getter and
- setter. In the setter we ensure that the new value is a boolean,
- but the real important change is that we call
- 'gdb.invalidate_cached_frames()'. This means that the backtrace
- will be updated if a user manually disables an unwinder (rather than
- calling the 'disable unwinder' command). It is not unreasonable to
- think that a user might register multiple unwinders (relating to
- some project) and have one command that disables/enables all the
- related unwinders. This command might operate by poking the enabled
- attribute of each unwinder object directly, after this commit, this
- would now work correctly.
-
- There's tests for all the changes, and lots of documentation updates
- that both cover the new changes, but also further improve (I think)
- the general documentation for GDB's Unwinder API.

- RISC-V: PR28789, Reject R_RISCV_PCREL relocations with ABS symbol in PIC/PIE.
- The non-preemptible SHN_ABS symbol with a pc-relative relocation should be
- disallowed when generating shared object (pic and pie). Generally, the
- following cases, which refer to pr25749, will cause a symbol be
- non-preemptible,
-
- * -pie, or -shared with -symbolic
- * STV_HIDDEN, STV_INTERNAL, STV_PROTECTED
- * Have dynamic symbol table, but without the symbol
- * VER_NDX_LOCAL
-
- However, PCREL_HI20/LO12 relocs are always bind locally when generating
- shared object, so not only the non-preemptible absolute symbol need to
- be disallowed, all absolute symbol references need but except that they
- are defined in linker script. If we also disallow the absolute symbol
- in linker script, then the glibc-linux toolchain build failed, so regard
- them as pc-relative symbols, just like what x86 did.
-
- Maybe we should add this check for all pc-relative relocations, rather
- than just handle in R_RISCV_PCREL relocs. Ideally, since the value of
- SHN_ABS symbol is a constant, only S - A relocations should be allowed
- in the shared object, so only BFD_RELOC_8/16/32/64 are allowed, which
- means R_RISCV_32/R_RISCV_64.

- gdb: move displaced_step_dump_bytes into gdbsupport (and rename)
- It was pointed out during review of another patch that the function
- displaced_step_dump_bytes really isn't specific to displaced stepping,
- and should really get a more generic name and move into gdbsupport/.
-
- This commit does just that. The function is renamed to
- bytes_to_string and is moved into gdbsupport/common-utils.{cc,h}. The
- function implementation doesn't really change. Much...
-
- ... I have updated the function to take an array view, which makes it
- slightly easier to call in a couple of places where we already have a
- gdb::bytes_vector. I've then added an inline wrapper to convert a raw
- pointer and length into an array view, which is used in places where
- we don't easily have a gdb::bytes_vector (or similar).
-
- Updated all users of displaced_step_dump_bytes.
-
- There should be no user visible changes after this commit.
-
- Finally, I ended up having to add an include of gdb_assert.h into
- array-view.h. When I include array-view.h into common-utils.h I ran
- into build problems because array-view.h calls gdb_assert.

- gdb: more debug output for displaced stepping
- While investigating a displaced stepping issue I wanted an easy way to
- see what GDB thought the original instruction was, and what
- instruction GDB replaced that with when performing the displaced step.
-
- We do print out the address that is being stepped, so I can track down
- the original instruction, I just need to go find the information
- myself.
-
- And we do print out the bytes of the new instruction, so I can figure
- out what the replacement instruction was, but it's not really easy.
-
- Also, the code that prints the bytes of the replacement instruction
- only prints 4 bytes, which clearly isn't always going to be correct.
-
- In this commit I remove the existing code that prints the bytes of the
- replacement instruction, and add two new blocks of code to
- displaced_step_prepare_throw. This new code prints the original
- instruction, and the replacement instruction. In each case we print
- both the bytes that make up the instruction and the completely
- disassembled instruction.
-
- Here's an example of what the output looks like on x86-64 (this is
- with 'set debug displaced on'). The two interesting lines contain the
- strings 'original insn' and 'replacement insn':
-
- (gdb) step
- [displaced] displaced_step_prepare_throw: displaced-stepping 2892655.2892655.0 now

- 0x00007ffff7e402c0 in puts () from /lib64/libc.so.6
- (gdb)
-
- One final note. For many targets that support displaced stepping (in
- fact all targets except ARM) the replacement instruction is always a
- single instruction. But on ARM the replacement could actually be a
- series of instructions.
-
- The debug code tries to handle this by disassembling the entire
- displaced stepping buffer. Obviously this might actually print more
- than is necessary, but there's (currently) no easy way to know how
- many instructions to disassemble; that knowledge is all locked in the
- architecture specific code. Still I don't think it really hurts, if
- someone is looking at this debug then hopefully they known what to
- expect.
-
- Obviously we can imagine schemes where the architecture specific
- displaced stepping code could communicate back how many bytes its
- replacement sequence was, and then our debug print code could use this
- to limit the disassembly. But this seems like a lot of effort just to
- save printing a few additional instructions in some debug output.
-
- I'm not proposing to do anything about this issue for now.

- [gdb/testsuite] Fix local-remote-host-native.exp for gdb.server tests

- ...

- FAIL: gdb.server/stop-reply-no-thread-multi.exp: target-non-stop=off: \
- to_disable=: set remote threads-packet off (timeout)
- ...
-
- This is due to this line in ${board}_spawn:
- ...
- set board_info($board,fileid) $spawn_id
- ...
-
- We have the following series of events:
- - gdb is spawned, setting fileid
- - a few gdb commands (set height etc) are send using fileid, arrive at gdb and
- are successful
- - gdbserver is spawned, overwriting fileid
- - the next gdb command is sent using fileid, so it's send
- to gdbserver instead of gdb, and we run into the timeout.
-
- There is some notion of current gdb, tracked in both gdb_spawn_id and fileid
- of the host board (see switch_gdb_spawn_id). And because the host and target
- board are the same, spawning something on the target overwrites the fileid on
- host, and consequently the current gdb.
-
- Fix this by only setting fileid when spawning gdb.

- Tested on x86_64-linux.

- Now gdb.server/*.exp passes for host+target board local-remote-host-native,

- gprofng: 30089 [display text] Invalid number of threads
- The real problem is that libcollector doesn't interpose thread_create@GLIBC_2.34
- We interpose a lot of libC functions (dlopen, fork, pthread_create, etc.).
- Some of these functions have versions. For example, dlopen@GLIBC_2.34,
- dlopen@GLIBC_2.17, dlopen@GLIBC_2.2.5, etc.
- We have to interpose each of the functions because we don't know
- which version of libC will be used during profiling.
- Historically, we have used three versions of scripts (mapfile.aarch64-Linux,
- mapfile.amd64-Linux, mapfile.intel-Linux).
- Three are not needed. One is enough
-
- The fixes below include:
- - merged all version symbols into one version script.
- - added new version symbols which are defined in latest versions of libC.
- - removed unused defines and duplicated code.
- - added the DCL_FUNC_VER macro to define the version symbols.
-
- Tested on x86_64 and aarch64 (OL8/OL9). No regression.

- It's also a bit more logical this way, as we don't have to pass down

- [gdb/testsuite] Skip do_self_tests on remote host
- In do_self_tests we try to find out the location of the gdb to debug, which
- will then be copied and renamed to xgdb.
-
- In principle, the host board specifies the location of GDB, on host.
-
- With remote host, we could upload that gdb from host to build/target, but we
- would miss the data directory (which is listed as the reason to skip
- do_self_tests for remote target).
-
- We could fix that by instead taking the gdb from build instead, but that
- wouldn't work with installed testing.
-
- It seems easier to just skip this on remote host.
-
- It could be made to work for the "[is_remote host] && [is_remote target]
- && host == target" scenario (see board local-remote-host-native.exp), but
- that doesn't seem worth the effort.

-
-2023-03-27 Tom de Vries <tdevries@suse.de>
-
- [gdb/testsuite] Add test-case gdb.dlang/dlang-start-2.exp
- For test-case gdb.dlang/dlang-start.exp, I run into:
- ...
- UNSUPPORTED: gdb.dlang/dlang-start.exp: require failed: can_compile d
- ...
-
- My distro has no support for gdc, but I'd like to have the test-case
- running and passing, so let's rewrite the test-case using dwarf assembly
- and add it alongside (rather than replacing it, because it's good to use
- actual compiler output if we have it available).
-
- My distro does have a package providing dmd, so let's mimic that debug info in
- the dwarf assembly. This gives us:
- ...
- (gdb) start ^M
- Temporary breakpoint 1 at 0x4004ab^M
- Starting program: dlang-start-2 ^M
- ^M
- Temporary breakpoint 1, 0x00000000004004ab in _Dmain ()^M
- ...
-
- The "_Dmain ()" should probably be "D main", I've filed PR30276 about that.
-
- Also add a "show language" to check that we automatically set the language
- correctly to D.
-
- Note that the dwarf assembly also describes main, otherwise the test-case
- doesn't function as regression test for commit 47fe57c9281 ("Fix "start" for
- D, Rust, etc").
-
- Tested on x86_64-linux.

- Use stdint types in coff internal_auxent
- long is a poor choice of type to store 32-bit values read from
- objects files by H_GET_32. H_GET_32 doesn't sign extend so tests like
- that in gdb/coffread.c for "negative" values won't work if long is
- larger than 32 bits. If long is 32-bit then code needs to be careful
- to not accidentally index negative array elements. (I'd rather see a
- segfault on an unmapped 4G array index than silently reading bogus
- data.) long is also a poor choice for x_sect.s_scnlen, which might
- have 64-bit values. It's better to use unsigned exact width types to
- avoid surprises.
-
- I decided to change the field names too, which makes most of this
- patch simply renaming. Besides that there are a few places where
- casts are no longer needed, and where printf format strings or tests
- need adjusting.

-
- The d compiler has a problem with the filename can_compile_d-105856.d, which
- contains the pid. The pid is added by gdb_simple_compile:
- ...

- ---------------------
- ../../../repos/binutils-gdb/gdb/thread.c:86: internal-error: inferior_thread: Assertion `current_thread_ != nullptr' failed.
- A problem internal to GDB has been detected,
- further debugging may prove unreliable.
- Quit this debugging session? (y or n)
-
- We also see failures across the testsuite if the tests get executed on a target
- that has native support for the pointer authentication feature. But
- gdb.base/break.exp and gdb.base/access-mem-running.exp are two examples of
- tests that run into errors and internal errors.
-
- This issue started after commit d88cb738e6a7a7179dfaff8af78d69250c852af1, which
- enabled more broad use of pointer authentication masks to remove non-address
- bits of pointers, but wasn't immediately detected because systems with native
- support for pointer authentication are not that common yet.
-
- The above crash happens because gdb is in the middle of handling an event,
- and do_target_wait_1 calls switch_to_inferior_no_thread, nullifying the
- current thread. This means a call to inferior_thread () will assert, and
- attempting to call get_current_regcache () will also call inferior_thread (),
- resulting in an assertion as well.
-
- target_has_registers was one function that seemed useful for detecting these
- types of situation where we don't have a register cache. The problem with that
- is the inconsistent state of inferior_ptid, which is used by
- target_has_registers.
-
- Despite the call to switch_to_no_thread in switch_to_inferior_no_thread from
- do_target_wait_1 in the backtrace above clearing inferior_ptid, the call to
- ps_xfer_memory sets inferior_ptid momentarily before reading memory:
-
- static ps_err_e
- ps_xfer_memory (const struct ps_prochandle *ph, psaddr_t addr,
- gdb_byte *buf, size_t len, int write)
- {
- scoped_restore_current_inferior restore_inferior;
- set_current_inferior (ph->thread->inf);
-
- scoped_restore_current_program_space restore_current_progspace;
- set_current_program_space (ph->thread->inf->pspace);
-
- scoped_restore save_inferior_ptid = make_scoped_restore (&inferior_ptid);
- inferior_ptid = ph->thread->ptid;
-
- CORE_ADDR core_addr = ps_addr_to_core_addr (addr);
-
- int ret;
- if (write)
- ret = target_write_memory (core_addr, buf, len);
- else
- ret = target_read_memory (core_addr, buf, len);
- return (ret == 0 ? PS_OK : PS_ERR);
- }
-
- Maybe this shouldn't happen, or maybe it is just an unfortunate state to be
- in. But this prevents the use of target_has_registers to guard against the
- lack of registers, since, although current_thread_ is still nullptr,
- inferior_ptid is valid and is not null_ptid.
-
- There is another crash scenario after we kill a previously active inferior, in
- which case the gdbarch will still say we support pointer authentication but we
- will also have no current thread (inferior_thread () will assert etc).
-
- If the target has support for pointer authentication, gdb needs to use
- a couple (or 4, for bare-metal) mask registers to mask off some bits of
- pointers, and for that it needs to access the registers.
-
- At some points, like the one from the backtrace above, there is no active
- thread/current regcache because gdb is in the middle of doing event handling
- and switching between threads.
-
- Simon suggested the use of inferior_ptid to fetch the register cache, as
- opposed to relying on the current register cache. Though we need to make sure
- inferior_ptid is valid (not null_ptid), I think this works nicely.
-
- With inferior_ptid, we can do safety checks along the way, making sure we have
- a thread to fetch a register cache from and checking if the thread is actually
- stopped or running.
-
- The following patch implements this idea with safety checks to make sure we
- don't run into assertions or errors. If any of the checks fail, we fallback to
- using a default mask to remove non-address bits of a pointer.
-
- I discussed with Pedro the possibility of caching the mask register values
- (which are per-process and can change mid-execution), but there isn't a good
- spot to cache those values. Besides, the mask registers can change constantly
- for bare-metal debugging when switching between exception levels.
-
- In some cases, it is just not possible to get access to these mask registers,
- like the case where threads are running. In those cases, using a default mask
- to remove the non-address bits should be enough.
-
- This can happen when we let threads run in the background and then we attempt
- to access a memory address (now that gdb is capable of reading memory even
- with threads running). Thus gdb will attempt to remove non-address bits
- of that memory access, will attempt to access registers, running into errors.
-
- Regression-tested on aarch64-linux Ubuntu 20.04.

- [gdb/testsuite] Fix unbalanced quotes in mi_expect_stop argument
- In proc mi_expect_stop there's a proc argument reason that's handled like so:
- ...
- set r "reason=\"$reason\","
- ...
-
- That's fine for say:
- ...
- set reason "foo"
- ...
- for which this evaluates to:
- ...
- set r "reason=\"foo\","
- ...
-
- But there are more complex uses, for instance:
- ...
- set reason "breakpoint-hit\",disp=\"keep\",bkptno=\"$decimal"
- ...
- which evaluates to:
- ...
- set r "\"breakpoint-hit\",disp=\"keep\",bkptno=\"$decimal\""
- ...
-
- Note how in this reason argument, the first two '\"' seems to form a pair
- surrounding ',disp=', which is not the case, which is confusing.
-
- Fix this by only adding the quotes in mi_expect_stop if the string doesn't
- already contain quotes, such that we have the more readable:
- ...
- set reason "\"breakpoint-hit\",disp=\"keep\",bkptno=\"$decimal\""
- ...
-
- Tested on x86_64-linux.

- [gdb/testsuite] Fix gdb.cp/m-static.exp regression on Ubuntu 20.04
- In commit 722c4596034 ("[gdb/testsuite] Fix gdb.cp/*.exp for remote host"), I
- needed to change ".*/" into "(.*/)?" in:
- ...
- gdb_test "info variable everywhere" \
- "File .*/m-static\[.\]h.*const int gnu_obj_4::everywhere;"
- ...
-
- However, due to the fact that I got this output:
- ...
- (gdb) info variable everywhere^M
- All variables matching regular expression "everywhere":^M
- ^M
- File /data/vries/gdb/src/gdb/testsuite/gdb.cp/m-static.h:^M
- 8: const int gnu_obj_4::everywhere;^M
- ^M
- File /data/vries/gdb/src/gdb/testsuite/gdb.cp/m-static1.cc:^M
- 8: const int gnu_obj_4::everywhere;^M
- ...
- I decided to make the matching somewhat stricter, to make sure that the two
- matched lines were subsequent.
-
- The commit turned out to be more strict than intended, and caused a regression
- on Ubuntu 20.04, where the output was instead:
- ...
- (gdb) info variable everywhere^M
- All variables matching regular expression "everywhere":^M
- ^M
- File /data/vries/gdb/src/gdb/testsuite/gdb.cp/m-static.h:^M
- 8: const int gnu_obj_4::everywhere;^M
- ...
-
- At that point I realized I'm looking at a bug (filed as PR symtab/30265),
- which manifests on openSUSE Leap 15.4 for native and readnow, and on Ubuntu
- 20.04 for readnow, but not for native.
-
- Before my commit, the test-case passed whether the bug manifested or not.
-
- After my commit, the test-case only passed when the bug manifested.
-
- Fix the test-case regression by reverting to the situation before the commit:
- pass whether the bug manifests or not. We could add an xfail for the PR, but
- I'm expecting a fix soon, so that doesn't look worth the effort.
-
- Tested on x86_64-linux, both on openSUSE Leap 15.4 and Ubuntu 20.04, both with
- native and readnow.

- This is needed when a single stub breaks BTI compatibility.

- gdb/riscv: add systemtap support
- This commit is initial support for SystemTap for RISC-V Linux. The
- following two tests exercise SystemTap functionality, and are showing
- many failures, which are all fixed by this commit:
-
- gdb.cp/exceptprint.exp
- gdb.base/stap-probe.exp
-
- One thing I wasn't sure about is if the SystemTap support should be
- Linux specific, or architecture specific. For aarch64, arm, ia64, and
- ppc, the SystemTap support seems to libe in the ARCH-linux-tdep.c
- file, while for amd64, i386, and s390 the implementation lives in
- ARCH-tdep.c. I have no idea which of these is the better choice -- or
- maybe both choices are correct in the right circumstances, and I'm
- just not aware of how to choose between them.
-
- Anyway, for this patch I selected riscv-tdep.c (though clearly, moving
- the changes to riscv-linux-tdep.c is trivial if anyone thinks that's a
- more appropriate location).
-
- The stap-probe.exp file tests immediate, register, and register
- indirect operands, all of which appear to be working fine with this
- commit. The generic expression support doesn't appear to be
- architecture specific, so I'd expect that to work fine too.

- gdb: remove gdbarch_displaced_step_fixup_p
- The comment on the gdbarch_displaced_step_fixup gdbarch method
- indicates that this method is optional and that GDB will perform some
- default if this method is not supplied. As such we define a predicate
- gdbarch_displaced_step_fixup_p.
-
- It may have been true at one point that the fixup method was optional,
- but it is no longer true. If this method is not defined and GDB tries
- to complete a displaced step, then GDB is going to crash.
-
- Additionally the gdbarch_displaced_step_fixup_p predicate is not used
- anywhere in GDB.
-
- In this commit I have removed the gdbarch_displaced_step_fixup_p
- predicate, and I have updated the validation check for the
- gdbarch_displaced_step_fixup method; if the
- gdbarch_displaced_step_copy_insn method is defined then the fixup
- method must also be defined.
-
- I believe I've manually checked all the current places where
- gdbarch_displaced_step_copy_insn is defined and they all also define
- the fixup method, so this change should cause no problems for anyone.
-
- There should be no user visible changes after this commit.

- gdb: make "maintenance info line-table" show relocated addresses again
- Commit 1acc9dca423f ("Change linetables to be objfile-independent")
- changed "maintenance info line-table" to print unrelocated addresses
- instead of relocated. This breaks a few tests on systems where that
- matters. The ones I see are:
-
- Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.base/consecutive.exp ...
- FAIL: gdb.base/consecutive.exp: stopped at bp, 2nd instr (missing hex prefix)
- Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.base/async.exp ...
- FAIL: gdb.base/async.exp: stepi&
- FAIL: gdb.base/async.exp: nexti&
- FAIL: gdb.base/async.exp: finish&
-
- These tests run "maintenance info line-table" to record the address of
- some lines, and then use these addresses in expected patterns. It
- therefore expects these addresses to match the runtime addresses,
- therefore the relocated addresses.
-
- Add back the relocated addresses, next to the unrelocated addresses,
- like so:
-
- INDEX LINE REL-ADDRESS UNREL-ADDRESS IS-STMT PROLOGUE-END
- 0 6 0x0000555555555119 0x0000000000001119 Y
- 1 7 0x000055555555511d 0x000000000000111d Y
- 2 8 0x0000555555555123 0x0000000000001123 Y
- 3 END 0x0000555555555125 0x0000000000001125 Y
-
- The unrelocated addresses can always be useful trying to map this
- information with a DWARF info dump.
-
- Adjust the is_stmt_addresses proc in the testsuite to match the new
- output.

- PowerPC: fix for gdb.reverse/finish-precsave.exp and gdb.reverse/finish-reverse.exp
-
- PPC64 multiple entry points, a normal entry point and an alternate entry
- point. The alternate entry point is to setup the Table of Contents (TOC)
- register before continuing at the normal entry point. When the TOC is
- already valid, the normal entry point is used, this is typically the case.
- The alternate entry point is typically referred to as the global entry
- point (GEP) in IBM. The normal entry point is typically referred to as
- the local entry point (LEP).
- .....
-
- Is causing regression failures on on PowerPC platforms. The regression
- failures are in tests:
-
- gdb.reverse/finish-precsave.exp
- gdb.btrace/tailcall.exp
- gdb.mi/mi-reverse.exp
- gdb.btrace/step.exp
- gdb.reverse/until-precsave.exp
- gdb.reverse/finish-reverse.exp
- gdb.btrace/tailcall-only.exp
-
- The issue is in gdb/infcmd.c, function finish_command. The value of the
- two new variables ALT_ENTRY_POINT and ENTRY_POINT are being initializezed
- to SAL.PC. However, SAL has just been declared. The value of SAL.PC is
- zero at this point. The intialization of ALT_ENTRY_POINT and ENTRY_POINT
- needs to be after the initialization of SAL.
-
- This patch moves the initialization of ALT_ENTRY_POINT and ENTRY_POINT
- variables to fix the regression failures.
-
- The patch has been tested on Power10 and on X86.

- [gdb/testsuite] Handle remotedir in remote_upload
- Dejagnu's remotedir implementation has support in remote_exec and
- remote_download, but not remote_upload.
-
- Consider the following scenario:
- - downloading an executable to target,
- - running it,
- - uploading a file produced by the executable
- while assuming remote target user remote-target with homedir
- /home/remote-target and remotedir set to /home/remote-target/tmp.
-
- Concretely, it looks like this:
- ...
- # binfile == "$outputs/gdb.abc/a.out"
- set target_binfile [remote_download target $binfile]
- # target_binfile == "/home/remote-target/tmp/a.out"
- remote_exec target $target_binfile
- # Running $target_binfile produced /home/remote-target/tmp/result.txt.
- set result [remote_upload target /home/remote-target/tmp/result.txt \
- $outputs/gdb.abc/result.txt]
- # result == $outputs/gdb.abc/result.txt.
- ...
-
- Add a remote_upload implementation that also handles remotedir in lib/gdb.exp,
- overriding dejagnu's remote_upload, such that we can simplify the
- remote_upload call to:
- ...
- set result [remote_upload target result.txt $outputs/gdb.abc/result.txt]
- ...
-
- Tested on x86_64-linux.

- gdb: fix crash during command completion
- In some cases GDB will fail when attempting to complete a command that
- involves a rust symbol, the failure can manifest as a crash.
-
- The problem is caused by the completion_match_for_lcd object being
- left containing invalid data during calls to cp_symbol_name_matches_1.
-
- The first question to address is why we are calling a C++ support
- function when handling a rust symbol. That's due to GDB's auto
- language detection for msymbols, in some cases GDB can't tell if a
- symbol is a rust symbol, or a C++ symbol.
-
- The test application contains symbols for functions which are
- statically linked in from various rust support libraries. There's no
- DWARF for these symbols, so all GDB has is the msymbols built from the
- ELF symbol table.
-
- Here's the problematic symbol that leads to our crash:
-
- mangled: _ZN4core3str21_$LT$impl$u20$str$GT$5parse17h5111d2d6a50d22bdE
- demangled: core::str::<impl str>::parse
-
- As an msymbol this is initially created with language auto, then GDB
- eventually calls symbol_find_demangled_name, which loops over all
- languages calling language_defn::sniff_from_mangled_name, the first
- language that can demangle the symbol gets assigned as the language
- for that symbol.
-
- Unfortunately, there's overlap in the mangled symbol names,
- some (legacy) rust symbols can be demangled as both rust and C++, see
- cplus_demangle in libiberty/cplus-dem.c where this is mentioned.
-
- And so, because we check the C++ language before we check for rust,
- then the msymbol is (incorrectly) given the C++ language.
-
- Now it's true that is some cases we might be able to figure out that a
- demangled symbol is not actually a valid C++ symbol, for example, in
- our case, the construct '::<impl str>::' is not, I believe, valid in a
- C++ symbol, we could look for ':<' and '>:' and refuse to accept this
- as a C++ symbol.
-
- However, I'm not sure it is always possible to tell that a demangled
- symbol is rust or C++, so, I think, we have to accept that some times
- we will get this language detection wrong.
-
- If we accept that we can't fix the symbol language detection 100% of
- the time, then we should make sure that GDB doesn't crash when it gets
- the language wrong, that is what this commit addresses.
-
- In our test case the user tries to complete a symbol name like this:
-
- (gdb) complete break pars
-
- This results in GDB trying to find all symbols that match 'pars',
- eventually we consider our problematic symbol, and we end up with a
- call stack that looks like this:
-
- #0 0x0000000000f3c6bd in strncmp_iw_with_mode
- #1 0x0000000000706d8d in cp_symbol_name_matches_1
- #2 0x0000000000706fa4 in cp_symbol_name_matches
- #3 0x0000000000df3c45 in compare_symbol_name
- #4 0x0000000000df3c91 in completion_list_add_name
- #5 0x0000000000df3f1d in completion_list_add_msymbol
- #6 0x0000000000df4c94 in default_collect_symbol_completion_matches_break_on
- #7 0x0000000000658c08 in language_defn::collect_symbol_completion_matches
- #8 0x0000000000df54c9 in collect_symbol_completion_matches
- #9 0x00000000009d98fb in linespec_complete_function
- #10 0x00000000009d99f0 in complete_linespec_component
- #11 0x00000000009da200 in linespec_complete
- #12 0x00000000006e4132 in complete_address_and_linespec_locations
- #13 0x00000000006e4ac3 in location_completer
-
- In cp_symbol_name_matches_1 we enter a loop, this loop repeatedly
- tries to match the demangled problematic symbol name against the user
- supplied text ('pars'). Each time around the loop another component
- of the symbol name is stripped off, thus, we check 'pars' against
- these options:
-
- core::str::<impl str>::parse
- str::<impl str>::parse
- <impl str>::parse
- parse
-
- As soon as we get a match the cp_symbol_name_matches_1 exits its loop
- and returns. In our case, when we're looking for 'pars', the match
- occurs on the last iteration of the loop, when we are comparing to
- 'parse'.
-
- Now the problem here is that cp_symbol_name_matches_1 uses the
- strncmp_iw_with_mode, and inside strncmp_iw_with_mode we allow for
- skipping over template parameters. This allows GDB to match the
- symbol name 'foo<int>(int,int)' if the user supplies 'foo(int,'.
- Inside strncmp_iw_with_mode GDB will record any template arguments
- that it has skipped over inside the completion_match_for_lcd object
- that is passed in as an argument.
-
- And so, when GDB tries to match against '<impl str>::parse', the first
- thing it sees is '<impl str>', GDB assumes this is a template argument
- and records this as a skipped region within the
- completion_match_for_lcd object. After '<impl str>' GDB sees a ':'
- character, which doesn't match with the 'pars' the user supplied, so
- strncmp_iw_with_mode returns a value indicating a non-match. GDB then
- removes the '<impl str>' component from the symbol name and tries
- again, this time comparing to 'parse', which does match.
-
- Having found a match, then in cp_symbol_name_matches_1 we record the
- match string, and the full symbol name within the
- completion_match_result object, and return.
-
- The problem here is that the skipped region, the '<impl str>' that we
- recorded in the penultimate loop iteration was never discarded, its
- still there in our returned result.
-
- If we look at what the pointers held in the completion_match_result
- that cp_symbol_name_matches_1 returns, this is what we see:
-
- core::str::<impl str>::parse
- | \________/ |
- | | '--- completion match string
- | '---skip range
- '--- full symbol name
-
- When GDB calls completion_match_for_lcd::finish, GDB tries to create a
- string using the completion match string (parse), but excluding the
- skip range, as the stored skip range is before the start of the
- completion match string, then GDB tries to do some weird string
- creation, which will cause GDB to crash.
-
- The reason we don't often see this problem in C++ is that for C++
- symbols there is always some non-template text before the template
- argument. This non-template text means GDB is likely to either match
- the symbol, or reject the symbol without storing a skip range.
-
- However, notice, I did say, we don't often see this problem. Once I
- understood the issue, I was able to reproduce the crash using a pure
- C++ example:
-
- template<typename S>
- struct foo
- {
- template<typename T>
- foo (int p1, T a)
- {
- s = 0;
- }
-
- S s;
- };
-
- int
- main ()
- {
- foo<int> obj (2.3, 0);
- return 0;
- }
-
- Then in GDB:
-
- (gdb) complete break foo(int
-
- The problem here is that the C++ symbol for the constructor looks like
- this:
-
- foo<int>::foo<double>(int, double)
-
- When GDB enters cp_symbol_name_matches_1 the symbols it examines are:
-
- foo<int>::foo<double>(int, double)
- foo<double>(int, double)
-
- The first iteration of the loop will match the 'foo', then add the
- '<int>' template argument will be added as a skip range. When GDB
- find the ':' after the '<int>' the first iteration of the loop fails
- to match, GDB removes the 'foo<int>::' component, and starts the
- second iteration of the loop.
-
- Again, GDB matches the 'foo', and now adds '<double>' as a skip
- region. After that the '(int' successfully matches, and so the second
- iteration of the loop succeeds, but, once again we left the '<int>' in
- place as a skip region, even though this occurs before the start of
- our match string, and this will cause GDB to crash.
-
- This problem was reported to the mailing list, and a solution
- discussed in this thread:
-
- https://sourceware.org/pipermail/gdb-patches/2023-January/195166.html
-
- The solution proposed here is similar to one proposed by the original
- bug reported, but implemented in a different location within GDB.
- Instead of placing the fix in strncmp_iw_with_mode, I place the fix in
- cp_symbol_name_matches_1. I believe this is a better location as it
- is this function that implements the loop, and it is this loop, which
- repeatedly calls strncmp_iw_with_mode, that should be resetting the
- result object state (I believe).
-
- What I have done is add an assert to strncmp_iw_with_mode that the
- incoming result object is empty.
-
- I've also added some other asserts in related code, in
- completion_match_for_lcd::mark_ignored_range, I make some basic
- assertions about the incoming range pointers, and in
- completion_match_for_lcd::finish I also make some assertions about how
- the skip ranges relate to the match pointer.
-
- There's two new tests. The original rust example that was used in the
- initial bug report, and a C++ test. The rust example depends on which
- symbols are pulled in from the rust libraries, so it is possible that,
- at some future date, the problematic symbol will disappear from this
- test program. The C++ test should be more reliable, as this only
- depends on symbols from within the C++ source code.
-
- Since I originally posted this patch to the mailing list, the
- following patch has been merged:
-
- commit 6e7eef72164c00d6a5a7b0bce9fa01f5481f33cb
- Date: Sun Mar 19 09:13:10 2023 -0600
-
- Use rust_demangle to fix a crash
-
- This solves the problem of a rust symbol ending up in the C++ specific
- code by changing the order languages are sorted. However, this new
- commit doesn't address the issue in the C++ code which was fixed with
- this commit.
-
- Given that the C++ issue is real, and has a reproducer, I'm still
- going to merge this fix. I've left the discussion of rust in this
- commit message as I originally wrote it, but it should be read within
- the context of GDB prior to commit 6e7eef72164c00d6a5a7.

- x86: drop identifier_chars[]
- It tries to resemble what's underlying is_part_of_name(), but doesn't
- quite achieve that: '$' for example is unconditionally marked as part of
- symbol names, but was included as identifier char for Intel syntax only.
- Note that i386_att_operand() checks for the immediate prefix first, so
- the wider coverage by starts_memory_operand() is has no real effect
- there, but it does matter for something like
-
- mov %fs:$dollar, %eax
-
- which previously wasn't accepted (but which clearly is a memory
- reference - there's no point in forcing people to parenthesize the
- symbol name). Similarly including '%' as an identfier for Intel syntax
- had no real significance to the rest of the assembler. If '%' was to be
- valid in (unquoted) symbol names, LEX_PCT would need to be defined.
-
- Note further that this also addresses the latent issue of a sub-target
- defining LEX_AT or LEX_QM to zero: That would make '@' and/or '?' no
- valid part of symbol names, but would have included them in what
- is_identifier_char() considers a valid part of a name. (There's a minor
- related issue which is actually being eliminated: te-interix.h allows
- '@' only in the middle of symbol names, yet starts_memory_operand()
- specifically looks at the first character of [possibly] a symbol name.)
-
- In parse_real_register() there's no point also checking is_name_ender()
- as at this point no character is marked solely LEX_END_NAME by any sub-
- target. Checking is_name_beginner() is also pointless as the hash lookup
- will fail anyway for a zero-length name.
-
- While touching the check in parse_real_register() also drop the
- "allow_naked_reg" part of the condition: This has only led to
- inconsistent error messages.

- SwapSources actually increases consistency among the templates: Like
- others which already have the attribute, these are all insns where the
- VEX.VVVV-encoded register comes first (or last when looking at the SDM).
-
- Note that the vexvvvv attribute now has merely boolean meaning anymore,
- in line with the SDM long having dropped the NDS/NDD/DDS concept of
- identifying encoding variants. The fallout will be taken care of
- subsequently, though, to not further clutter the change here.
-
- As to the TILEZERO special case: If more instructions like this
- appeared, a new attribute would likely be the way to go. But as long as

-
- This patch fixes the bug by reordering the language constants so that

- gdb: don't use the global thread-id in the saved breakpoints file

-
- There's a multi-inferior test that confirms the saved breakpoints file

- Fix line table regression
- Simon pointed out a line table regression, and after a couple of false
- starts, I was able to reproduce it by hand using his instructions.
-
- The bug is that most of the code in do_mixed_source_and_assembly uses
- unrelocated addresses, but one spot does:
-
- pc = low;
-
- ... after the text offset has been removed.
-
- This patch fixes the problem by introducing a new type to represent
- unrelocated addresses in the line table. This prevents this sort of
- bug to some degree (it's still possible to manipulate a CORE_ADDR in a
- bad way, this is unavoidable).
-
- However, this did let the compiler flag a few spots in that function,
- and now it's not possible to compare an unrelocated address from a
- line table with an ordinary CORE_ADDR.
-
- Regression tested on x86-64 Fedora 36, though note this setup never
- reproduced the bug in the first place. I also tested it by hand on
- the disasm-optim test program.

- gdb: introduce bp_loc_tracepoint
- Since commit cb1e4e32c2d9 ("catch catch/throw/rethrow", breakpoint ->
- catchpoint), this simple tracing scenario does not work:
-
- $ gdb/gdb -nx -q --data-directory=gdb/data-directory ./test
- Reading symbols from ./test...
- (gdb) tar rem :1234
- Remote debugging using :1234
- Reading symbols from /lib64/ld-linux-x86-64.so.2...
- (No debugging symbols found in /lib64/ld-linux-x86-64.so.2)
- 0x00007ffff7fe5730 in ?? () from /lib64/ld-linux-x86-64.so.2
- (gdb) trace do_something
- Tracepoint 1 at 0x555555555144: file test.c, line 5.
- (gdb) tstart
- (gdb) continue
- Continuing.
- Target returns error code '01'.
-
- The root cause is that the bp_location::nserted flag does not transfer
- anymore from an old bp_location to the new matching one. When a shared
- library gets loaded, GDB computes new breakpoint locations for each
- breakpoint in update_breakpoint_locations. The new locations are in the
- breakpoint::loc chain, while the old locations are still in the
- bp_locations global vector. Later, update_global_location_list is
- called. It tries to map old locations to new locations, and if
- necessary transfer some properties, like the inserted flag.
-
- Since commit cb1e4e32c2d9, the inserted flag isn't transferred for
- locations of tracepoints. This is because bl_address_is_meaningful used
- to be implemented like this:
-
- static int
- breakpoint_address_is_meaningful (struct breakpoint *bpt)
- {
- enum bptype type = bpt->type;
-
- return (type != bp_watchpoint && type != bp_catchpoint);
- }
-
- and was changed to this:
-
- static bool
- bl_address_is_meaningful (bp_location *loc)
- {
- return loc->loc_type != bp_loc_other;
- }
-
- Because locations for tracepoints have the bp_loc_other type,
- bl_address_is_meaningful started to return false for them, where it
- returned true before. This made update_global_location_list skip the
- part where it calls swap_insertion.
-
- I think this can be solved by introduced a new bp_loc_tracepoint
- bp_loc_type.
-
- I don't know if it's accurate, but my understanding is that bp_loc_type
- describes roughly "how do we ask the target to insert that location".
- bp_loc_software_breakpoint are inserted using
- target_ops::insert_breakpoint_location. bp_loc_hardware_breakpoint are
- inserted using target_ops::insert_hw_breakpoint.
- bp_loc_software_watchpoint and bp_loc_hardware_watchpoint are inserted
- using target_ops::insert_watchpoint. For all these, the address is
- meaningful, as we ask the target to insert the point at a specific
- address. bp_loc_other is a catch-all for "the rest", in practice for
- catchpoints that don't have a specific address (hence why
- bl_address_is_meaningful returns false for them). For instance,
- inserting a signal catchpoint is done by asking the target to report
- that specific signal. GDB doesn't associate an address to that.
-
- But tracepoints do have a meaningful address to thems, so they can't be
- bp_loc_other, with that logic. They also can't be
- bp_loc_software_breakpoint, because we don't want GDB to insert
- breakpoints for them (even though they might be implemented using
- software breakpoints by the remote side). So, the new bp_loc_tracepoint
- type describes that the way to insert these locations is with
- target_ops::download_tracepoint. It makes bl_address_is_meaningful
- return true for them. And they'll be ignored by insert_bp_location and
- GDB won't try to insert a memory breakpoint for them.
-
- With this, I see a few instances of 'Target returns error code: 01'
- disappearing from gdb.log, and the results of gdb.trace/*.exp improve a
- little bit:
-
- -# of expected passes 3765
- +# of expected passes 3781
- -# of unexpected failures 518
- +# of unexpected failures 498
-
- Things remain quite broken in that area though.

-
- PowerPC: fix for gdb.reverse/finish-precsave.exp and gdb.reverse/finish-reverse.exp
- PPC64 multiple entry points, a normal entry point and an alternate entry
- point. The alternate entry point is to setup the Table of Contents (TOC)
- register before continuing at the normal entry point. When the TOC is
- already valid, the normal entry point is used, this is typically the case.
- The alternate entry point is typically referred to as the global entry
- point (GEP) in IBM. The normal entry point is typically referred to as
- the local entry point (LEP).
-
- When GDB is executing the finish command in reverse, the function
- finish_backward currently sets the break point at the alternate entry point.
- This issue is if the function, when executing in the forward direction,
- entered the function via the normal entry point, execution in the reverse
- direction will never sees the break point at the alternate entry point. In
- this case, the reverse execution continues until the next break point is
- encountered thus stopping at the wrong place.
-
- This patch adds a new address to struct execution_control_state to hold the
- address of the alternate entry point (GEP). The finish_backwards function
- is updated, if the stopping point is between the normal entry point (LEP)
- and the end of the function, a breakpoint is set at the normal entry point.
- If the stopping point is between the entry points, a breakpoint is set at
- the alternate entry point. This ensures that GDB will always stop at the
- normal entry point. If the function did enter via the alternate entry
- point, GDB will detect that and continue to execute backwards in the
- function until the alternate entry point is reached.
-
- The patch fixes the behavior of the reverse-finish command on PowerPC to
- match the behavior of the command on other platforms, specifically X86.
- The patch does not change the behavior of the command on X86.
-
- A new test is added to verify the reverse-finish command on PowerPC
- correctly stops at the instruction where the function call is made.
-
- The patch fixes 11 regression errors in test gdb.reverse/finish-precsave.exp
- and 11 regression errors in test gdb.reverse/finish-reverse.exp.
-
- The patch has been tested on Power 10 and X86 processor with no new
- regression failures.

- one missing line which the user has to figure out for themselves. By
- reordering the sections, it is now obvious that the registration
- should be included in the skeleton code, and the example is therefore
- almost complete.
-
- Additionally, in the example skeleton code the way in which the
- frame-id was being built (using the current stack point and program
- counter is (a) not correct, and (b) counter to what is laid out in the
- 'Unwinder Input' section when describing building a frame-id.
-
- I've removed the incorrect code and replaced it with more generic
- comments indicating what needs to be done. As the actual actions that
- need to be performed are both architecture specific, and dependent on
- the function being unwound, it's almost impossible to include more
- exact code here, but I think what I'm proposing is less misleading
- than what we had before.
-
- I've also added more cross references.

- gdb: add gdbarch::displaced_step_buffer_length
- The gdbarch::max_insn_length field is used mostly to support displaced
- stepping; it controls the size of the buffers allocated for the
- displaced-step instruction, and is also used when first copying the
- instruction, and later, when fixing up the instruction, in order to
- read in and parse the instruction being stepped.
-
- However, it has started to be used in other places in GDB, for
- example, it's used in the Python disassembler API, and it is used on
- amd64 as part of branch-tracing instruction classification.
-
- The problem is that the value assigned to max_insn_length is not
- always the maximum instruction length, but sometimes is a multiple of
- that length, as required to support displaced stepping, see rs600,
- ARM, and AArch64 for examples of this.
-
- It seems to me that we are overloading the meaning of the
- max_insn_length field, and I think that could potentially lead to
- confusion.
-
- I propose that we add a new gdbarch field,
- gdbarch::displaced_step_buffer_length, this new field will do
- exactly what it says on the tin; represent the required displaced step
- buffer size. The max_insn_length field can then do exactly what it
- claims to do; represent the maximum length of a single instruction.
-
- As some architectures (e.g. i386, and amd64) only require their
- displaced step buffers to be a single instruction in size, I propose
- that the default for displaced_step_buffer_length will be the
- value of max_insn_length. Architectures than need more buffer space
- can then override this default as needed.
-
- I've updated all architectures to setup the new field if appropriate,
- and I've audited all calls to gdbarch_max_insn_length and switched to
- gdbarch_displaced_step_buffer_length where appropriate.
-
- There should be no user visible changes after this commit.

- gdbarch: make invalid=True the default for all Components
- This commit switches the default value for the 'invalid' field from
- False to True. All components that previous set the invalid field to
- True explicitly have had the field removed.
-
- I think that True is a good choice for the default, this means that we
- now get the validity checks by default, and if anyone adds a new
- Component they need to make a choice to add an 'invalid=False' line
- and disable the validation.
-
- The flip side of this is that 'invalid=False' seems to be far more
- common than 'invalid=True'. But I don't see a huge problem with this,
- we shouldn't be aiming to reduce our typing, rather we should choose
- based on which is least likely to introduce bugs. I think assuming
- that we should do a validity check will achieve that.
-
- Some additional components need to have an 'invalid=False' line added
- to their definition, these are components that have a predefault
- value, which is sufficient; the tdep code doesn't need to replace this
- value if it doesn't want to.
-
- Without adding the 'invalid=False' these components would be
- considered to be invalid if they have not changed from their
- predefault value -- but the predefault is fine.
-
- There's no change in the generated code after this commit, so there
- will be no user visible changes after this commit.

- gdbarch: remove some unneeded predefault="0" from gdbarch_components.py
- I noticed that there are a bunch of 'predefault="0"' lines in
- gdbarch_components.py, and that some (just some, not all) of these are
- not needed.
-
- The gdbarch is already zero initialized, but these lines seem to
- exists so that we can know when to compare against "0" and when to
- compare against "NULL". At least, this seems to be useful in some
- places in the generated code.
-
- Specifically, if we remove the predefault="0" line from the
- max_insn_length component then we end up generating a line like:
-
- gdb_assert (gdbarch->max_insn_length != NULL);
-
- which doesn't compile as we compare a ULONGEST to NULL.
-
- In this commit I remove all the predefault="0" lines that I claim are
- obviously not needed. These are lines for components that are not
- Values (i.e. the component holds a function pointer anyway), or for
- Value components that hold a pointer type, in which case using NULL is
- fine.
-
- The only changes after this commit are some fields that have nullptr
- as their initial value, and gcore_bfd_target now compares to NULL not
- 0 in gdbarch_gcore_bfd_target_p, which, given the field is of type
- 'const char *', seems like an improvement.

- gdbarch: improve generation of validation in gdbarch getters
- We currently generate some validation code within the gdbarch getter
- methods.
-
- This commit adjusts the algorithm used to generate this validation
- slightly to make the gdbarch.py code (I think) clearer; there's no
- significant changes to what is generated.
-
- The validation algorithm for gdbarch values is now:
-
- - If the Value has an 'invalid' field that is a string, use that for
- validation,
-
- - If the Value has its 'predicate' field set to true, then check the
- predicate returns true, this ensures the predicate has been
- called,
-
- - If the Value has its 'invalid' field set to True, or the Value has
- 'postdefault' field, then check the fields has changed from its
- initial value,
-
- - Otherwise no validation is performed.
-
- The only changes after this commit are:
-
- - Some comments change slightly, and
-
- - For 'gcore_bfd_target' and 'max_insn_length' we now validate by
- calling the predicate rather than checking the field value
- directly, the underlying check being performed is unchanged
- though.
-
- There should be no user visible changes after this commit.

- gdbarch: use predefault for more value components within gdbarch
- For some reason the following value components of gdbarch:
-
- bfloat16_format
- half_format
- float_format
- double_format
- long_double_format
- so_ops
-
- All use a postdefault but no predefault to set the default value for
- the component.
-
- As the postdefault values for these components are all constant
- pointers that don't depend on other fields within the gdbarch, then I
- don't see any reason why we couldn't use a predefault instead.
-
- So lets do that.

-
- gdb/gdbarch: remove the 'invalid=None' state from gdbarch_components.py
- This commit ensures that the 'invalid' property of all components is
- either True, False, or a string.
-
- Additionally, this commit allows a component to have both a predicate
- and for the 'invalid' property to be a string.
-
- Removing the option for 'invalid' to be None allows us to simplify the
- algorithms in gdbarch.py a little.
-
- Allowing a component to have both a predicate and an 'invalid' string
- means that we can validate the value that a tdep sets into a field,
- but also allow a predicate to ensure that the field has changed from
- the default.
-
- This functionality isn't going to be used in this series, but I have
- tested it locally and believe that it would work, and this might make
- it easier for others to add new components in the future.
-
- In gdbarch_types.py, I've updated the type annotations to show that
- the 'invalid' field should not be None, and I've changed the default
- for this field from None to False.
-
- The change to using False as the default is temporary. Later in this
- series I'm going to change the default to True, but we need more fixes
- before that can be done.
-
- Additionally, in gdbarch_types.py I've removed an assert from
- Component.get_predicate. This assert ensured that we didn't have the
- predicate field set to True and the invalid field set to a string.
- However, no component currently uses this configuration, and after
- this commit, that combination is now supported, so the assert can be
- removed.
-
- As a consequence of the gdbarch_types.py changes we see some
- additional comments generated in gdbarch.c about verification being
- skipped due to the invalid field being False. This comment is inline
- with plenty of other getters that also have a similar comment. Plenty
- of the getters do have validation, so I think it is reasonable to have
- a comment noting that the validation has been skipped for a specific
- reason, rather than due to some bug.
-
- In gdbarch_components.py I've had to add 'invalid=True' for two
- components: gcore_bfd_target and max_insn_length, without this the
- validation in the gdbarch getter would disappear.
-
- And in gdbarch.py I've reworked the logic for generating the
- verify_gdbarch function, and for generating the getter functions.
-
- The logic for generating the getter functions is still not ideal, I
- ended up having to add this additional logic block:
-
- elif c.postdefault is not None and c.predefault is not None:
- print(" /* Check variable changed from pre-default. */", file=f)
- print(f" gdb_assert (gdbarch->{c.name} != {c.predefault});", file=f)
-
- which was needed to ensure we continued to generate the same code as
- before, without this the fact that invalid is now False when it would
- previously have been None, meant that we dropped the gdb_assert in
- favour of a comment like:
-
- print(f" /* Skip verify of {c.name}, invalid_p == 0 */", file=f)
-
- which is clearly not a good change. We could potentially look at
- improving this in a later commit, but I don't plan to do that in this
- series.

- gdb/gdbarch: split postdefault setup from invalid check in gdbarch.py
- Restructure how gdbarch.py generates the verify_gdbarch function.
- Previously the postdefault handling was bundled together with the
- validation. This means that a field can't have both a postdefault,
- and set its invalid attribute to a string.
-
- This doesn't seem reasonable to me, I see no reason why a field can't
- have both a postdefault (used when the tdep doesn't set the field),
- and an invalid expression, which can be used to validate the value
- that a tdep might set.
-
- In this commit I restructure the verify_gdbarch generation code to

- Fix crash in inside_main_func
- gdb 13.1 crashes while running the rust compiler's debugger tests.
- The crash has a number of causes.
-
- First, the rust compiler still uses the C++-like _Z mangling, but with
- its own twist -- some hex digits added to the end of a symbol. So,
- while gdb finds the correct name of "main":
-
- (top-gdb) p name
- $13 = 0x292e0c0 "rustc_gdb_1031745::main"
-
- It isn't found in the minsyms, because C++ demangling yields:
-
- [99] t 0x90c0 _ZN17rustc_gdb_10317454main17h5b5be7fe16a97225E section .text rustc_gdb_1031745::main::h5b5be7fe16a97225 zko06yobckx336v
-
- This could perhaps be fixed. I also filed a new PR to suggest
- preferring the linkage name of the main program.
-
- Next, the rust compiler emits both a DW_TAG_subprogram and a
- DW_TAG_namespace for "main". This happens because the file is named
- "main.rs" -- i.e., the bug is specific to the source file name. The
- crash also seems to require the nested function inside of 'main', at
- least for me. The namespace always is generated, but perhaps this
- changes the ordering in the DWARF.
-
- When inside_main_func looks up the main symbol, it finds the namespace
- symbol rather than the function. (I filed a bug about fixing gdb's
- symbol tables -- long overdue.)
-
- Meanwhile, as I think it's important to fix this crash sooner rather
- than later, this patch changes inside_main_func to check that the
- symbol that is found is LOC_BLOCK. This perhaps should have been done
- in the first place, anyway.

- arm: Expand documentation of XML features
- The documentation of the XML features for Arm targets is very brief. I have
- received feedback saying it is quite unclear from the perspective of the
- debugging servers what should be defined in the XML features, how and
- what the outcome is in gdb.
-
- This patch attempts to clarify a bit more what all the possible features are.

- Constify linetables
- Linetables no longer change after they are created. This patch
- applies const to them.
-
- Note there is one hack to cast away const in mdebugread.c. This code
- allocates a linetable using 'malloc', then later copies it to the
- obstack. While this could be cleaned up, I chose not to do so because
- I have no way of testing it.

- Change linetables to be objfile-independent
- This changes linetables to not add the text offset to the addresses
- they contain. I did this in a few steps, necessarily combined
- together in one patch: I renamed the 'pc' member to 'm_pc', added the
- appropriate accessors, and then recompiled. Then I fixed all the
- errors. Where possible I generally chose to use the raw_pc accessor,
- as it is less expensive.
-
- Note that this patch discounts the possibility that the text section
- offset might cause wraparound in the addresses in the line table.
- However, this was already discounted -- in particular,
- objfile_relocate1 did not re-sort the table in this scenario. (There
- was a bug open about this, but as far as I can tell this has never
- happened, it's not even clear what inspired that bug.)

- PR gdb/30214: Prefer local include paths to system include paths
- Some systems may install binutils headers into a system location
- (e.g. /usr/local/include on FreeBSD) which may also include headers
- for other external packages used by GDB such as zlib or zstd. If a
- system include path such as /usr/local/include is added before local
- include paths to directories within a clone or release tarball, then
- headers from the external binutils package are used which can result
- in build failures if the external binutils package is out of sync with
- the version of GDB being built.
-
- To fix, sort the include paths in INTERNAL_CFLAGS_BASE to add CFLAGS
- for "local" componenets before external components.

- [gdb/testsuite] Fix gdb.python/py-cmd.exp
- [ Using $pp as shorthand for the pagination prompt
- "--Type <RET> for more, q to quit, c to continue without paging--". ]
-
- The test-case gdb.python/py-cmd.exp passes, but the handling of the
- test_multiline command output looks a bit odd:
- ...
- (gdb) test_multiline
- test_multiline output
- ...
- test_multiline output
- $ppPASS: gdb.python/py-cmd.exp: verify pagination from test_multiline
- q

- Quit
- (gdb) test_multiline
- test_multiline output
- ...
- test_multiline output
- $ppPASS: gdb.python/py-cmd.exp: verify pagination from test_multiline: q
- ...
-
- What happens is:
- - a test_multiline command is issued
- - some output is printed, followed by a pagination prompt
- - the test-case concludes that pagination occurred, and produces a PASS
- - "q\n" is replied to the pagination prompt
- - without waiting for response to the "q\n", another test_multiline command is
- issued
- - in response to the "q\n" we get "Quit\n(gdb) "
- - some output is printed, followed by a pagination prompt
- - the test-case concludes that there's a valid response to the "q\n", and
- produces a PASS, consuming the second pagination prompt, but without a reply.
-
- My conclusion is that the second test_multiline command is unintentional, so fix
- this by removing it.
-
- Without it, we have the more straightforward:
- ...
- (gdb) test_multiline
- test_multiline output
- ...
- test_multiline output
- $ppPASS: gdb.python/py-cmd.exp: verify pagination from test_multiline

- Arm64/gas: drop redundant feature prereqs
- Logic exists to deal with prereqs or prereqs, and in many cases
- transitive prereqs are already not spelled out explicitly. Drop further
- ones:
- - FP is already a prereq to F16,
- - SIMD and F16 are already prereqs to COMPNUM, and
- - SVE2 and BFLOAT16 are already prereqs to SME.
-

- A number of newer features are really SIMD or FP extensions, but don't
- have this properly specified.
-
- x86: decouple broadcast type and bytes fields
- Keep both representing exclusively what was parsed from input, to avoid
- the need for (potentially bogus) calculations when processing .insn.
-
- x86-64: adjust REX-prefix part of SSE2AVX test
- Before altering how build_modrm_byte() works, arrange for this part of
- the testcase to actually use distinguishable source and destination
- register numbers, such that incorrect propagation of, in particular, the
- high bit encodings (from REX to VEX) can be noticed (in turn
- specifically assertions [not] triggering in the respective code).

-
- x86: move more disp processing out of md_assemble()
- Put it in optimize_disp() such that it can then be re-used by .insn
- handling. The movement makes it necessary (or at least very desirable,
- to avoid introducing a fragile cast) to convert to local variable to
- "unsigned", which in turn requires an adjustment to the pre-existing
- loop header.
-
- Having the caller pass in the specific template under consideration has
- another benefit then: We can replace the two uses of current_templates
- in the function as well, thus no longer looking at some merely "related"
- template. (This may allow further tightening, but if so that's to be the
- subject of another change.)

- The problem is that the kill command:
- ...
- remote_exec target "kill -9 $gdbserver_pid"
- ...
- intended to kill gdbserver instead tries to kill the ssh client session in
- which the gdbserver runs, and fails because it's trying as the remote target
- user (remote-target on localhost) to kill a pid owned by the the build user
- ($USER on localhost).

- [gdb/testsuite] Fix gdb.server/server-kill.exp for remote target
- In commit 80dc83fd0e7 ("gdb/remote: handle target dying just before a stepi")
- an observation is made that test-case gdb.server/server-kill.exp claims to
- kill gdbserver, but actually kills the inferior. Consequently, the commit
- adds testing of killing gdbserver alongside.
-
- The problem is that:
- - the original observation is incorrect (possibly caused by misreading getppid
- as getpid)
- - consequently, the test-case doesn't test killing the inferior, instead it
- tests killing gdbserver twice
- - the method to get the gdbserver PID added in the commit doesn't work
- for target board remote-gdbserver-on-localhost, it returns the
- PID of the ssh client session instead.
-
- Fixing the method for getting the inferior PID gives us fails, and there's no
- evidence that killing the inferior ever worked.
-
- So, fix this by reverting the commit and just killing gdbserver, using the
- original method of getting the gdbserver PID which does work for target board
- remote-gdbserver-on-localhost.
-
- Tested on x86_64-linux.

- [gdb/testsuite] Fix gdb.server/connect-with-no-symbol-file.exp for remote target
- Test-case gdb.server/connect-with-no-symbol-file.exp fails with target board
- remote-gdbserver-on-localhost.
-
- The problem is here:
- ...
- set target_exec [gdb_remote_download target $binfile.bak $binfile]
- ...
- A "gdb_remote_download target" copies from build to target. So $binfile is
- assumed to be a target path, but it's actually a build path.
-
- Fix this by:
- - fist copying $binfile.bak to $binfile, and
- - simply doing [gdb_remote_download target $binfile].
-
- Then, $binfile.bak is created here:
- ...
- # Make sure we have the original symbol file in a safe place to copy from.
- gdb_remote_download host $binfile $binfile.bak
- ...
- and since "gdb_remote_download host" copies from build to host, $binfile.bak
- is assumed to be a host path, but it's actually a build path. This happens to
- cause no problems in this configuration (because build == host), but it would
- for a remote host configuration.
-
- So let's fix this by making build rather than host the "safe place to copy
- from".
-
- Tested on x86_64-linux.

- gdb/amdgpu: provide dummy implementation of gdbarch_return_value_as_value
- The AMD GPU support has been merged shortly after commit 4e1d2f5814b2
- ("Add new overload of gdbarch_return_value"), which made it mandatory
- for architectures to provide either a return_value or
- return_value_as_value implementation. Because of my failure to test
- properly after rebasing and before pushing, we get this with the current
- master:
-
- $ gdb ./gdb -nx --data-directory=data-directory -q -ex "set arch amdgcn:gfx1010" -batch
- /home/simark/src/binutils-gdb/gdb/gdbarch.c:517: internal-error: verify_gdbarch: the following are invalid ...
- return_value_as_value
-
- I started trying to change GDB to not force architectures to provide a
- return_value or return_value_as_value implementation, but Andrew pointed
- out that any serious port will have an implementation one day or
- another, and it's easy to add a dummy implementation in the mean time.
- So it's better to not complicate the core of GDB to know how to deal
- with this.
-
- There is an implementation of return_value in the downstream ROCgdb port
- (which we'll need to convert to the new return_value_as_value), which
- we'll contribute soon-ish. In the mean time, add a dummy implementation
- of return_value_as_value to avoid the failed assertion.

- Clean up attribute reprocessing
- I ran across the attribute reprocessing code recently and noticed that
- it unconditionally sets members of the CU when reading a DIE. Also,
- each spot reading attributes needs to be careful to "reprocess" them
- as a separate step.
-
- This seemed excessive to me, because while reprocessing applies to any
- DIE, setting the CU members is only necessary for the toplevel DIE in
- any given CU.
-
- This patch introduces a new read_toplevel_die function and changes a
- few spots to call it. This is easily done because reading the
- toplevel DIE is already special.
-
- I left the reprocessing flag and associated checks in attribute. It
- could be stripped out, but I am not sure it would provide much value
- (maybe some iota of performance).

- gdb: make interp::m_name an `const char *`

- gdbsupport: ignore -Wenum-constexpr-conversion in enum-flags.h
- When building with clang 16, we get:
-
- CXX gdb.o
- In file included from /home/smarchi/src/binutils-gdb/gdb/gdb.c:19:
- In file included from /home/smarchi/src/binutils-gdb/gdb/defs.h:65:
- /home/smarchi/src/binutils-gdb/gdb/../gdbsupport/enum-flags.h:95:52: error: integer value -1 is outside the valid range of values [0, 15] for this enumeration type [-Wenum-constexpr-conversion]
- integer_for_size<sizeof (T), static_cast<bool>(T (-1) < T (0))>::type
- ^
-
- The error message does not make it clear in the context of which enum
- flag this fails (i.e. what is T in this context), but it doesn't really
- matter, we have similar warning/errors for many of them, if we let the
- build go through.
-
- clang is right that the value -1 is invalid for the enum type we cast -1
- to. However, we do need this expression in order to select an integer
- type with the appropriate signedness. That is, with the same signedness
- as the underlying type of the enum.
-
- I first wondered if that was really needed, if we couldn't use
- std::underlying_type for that. It turns out that the comment just above
- says:
-
- /* Note that std::underlying_type<enum_type> is not what we want here,
- since that returns unsigned int even when the enum decays to signed
- int. */
-
- I was surprised, because std::is_signed<std::underlying_type<enum_type>>
- returns the right thing. So I tried replacing all this with
- std::underlying_type, see if that would work. Doing so causes some
- build failures in unittests/enum-flags-selftests.c:

-
- This is a bit hard to decode, but basically enumerations have the
- following funny property that they decay into a signed int, even if
- their implicit underlying type is unsigned. This code:
-
- enum A {};
- enum B {};
-
- int main() {
- std::cout << std::is_signed<std::underlying_type<A>::type>::value
- << std::endl;
- std::cout << std::is_signed<std::underlying_type<B>::type>::value
- << std::endl;
- auto result = true ? A() : B();
- std::cout << std::is_signed<decltype(result)>::value << std::endl;
- }
-
- produces:
-
- 0
- 0
- 1
-
- So, the "CHECK_VALID" above checks that this property works for enum flags the
- same way as it would if you were using their underlying enum types. And
- somehow, changing integer_for_size to use std::underlying_type breaks that.
-
- Since the current code does what we want, and I don't see any way of doing it
- differently, ignore -Wenum-constexpr-conversion around it.

- gdb/testsuite: use `kill -FOO` instead of `kill -SIGFOO`

- 23 return 0;^M
- FAIL: gdb.base/bg-exec-sigint-bp-cond.exp: no force memory write: SIGINT does not interrupt background execution (timeout)
-
- This is because it uses the kill command built-in the dash shell, and
- using the SIG prefix with kill does not work with dash's kill. The
- difference is listed in the documentation for bash's POSIX-correct mode
- [1]:
-
- The kill builtin does not accept signal names with a ‘SIG’ prefix.
-
- Replace SIGINT with INT in that test.
-
- By grepping, I found two other instances (gdb.base/sigwinch-notty.exp
- and gdb.threads/detach-step-over.exp). Those were not problematic on my
- system though. Since they are done through remote_exec, they don't go
- through the shell and therefore invoke /bin/kill. On my Arch Linux,
- it's:
-
- $ /bin/kill --version
- kill from util-linux 2.38.1 (with: sigqueue, pidfd)
-
- and on my Ubuntu:
-
- $ /bin/kill --version
- kill from procps-ng 3.3.17
-
- These two implementations accept "-SIGINT". But according to the POSIX
- spec [2], the kill utility should recognize the signal name without the
- SIG prefix (if it recognizes them with the SIG prefix, it's an
- extension):
-
- -s signal_name
- Specify the signal to send, using one of the symbolic names defined
- in the <signal.h> header. Values of signal_name shall be recognized
- in a case-independent fashion, without the SIG prefix. In addition,
- the symbolic name 0 shall be recognized, representing the signal
- value zero. The corresponding signal shall be sent instead of SIGTERM.
- -signal_name
- [XSI] [Option Start]
- Equivalent to -s signal_name. [Option End]
-
- So, just in case some /bin/kill implementation happens to not recognize
- the SIG prefixes, change these two other calls to remove the SIG
- prefix.

- gdb: fix -Wmaybe-uninitialized warning in value.c
- Since commit 11470e70ea0d ("gdb: store internalvars in an std::map"), bulding
- with -O2, with g++ 11.3.0 on Ubuntu 22.04, I see:
-
- CXX value.o
- In constructor ‘internalvar::internalvar(internalvar&&)’,
- inlined from ‘constexpr std::pair<_T1, _T2>::pair(_U1&&, _U2&&) [with _U1 = const char*&; _U2 = internalvar; typename std::enable_if<(std::_PCC<true, _T1, _T2>::_MoveConstructiblePair<_U1, _U2>() && std::_PCC<true, _T1, _T2>::_ImplicitlyMoveConvertiblePair<_U1, _U2>()), bool>::type <anonymous> = true; _T1 = const char*; _T2 = internalvar]’ at /usr/include/c++/11/bits/stl_pair.h:353:35,

- inlined from ‘internalvar* create_internalvar(const char*)’ at /home/smarchi/src/binutils-gdb/gdb/value.c:1933:52:

- 1933 | auto pair = internalvars.emplace (std::make_pair (name, internalvar (name)));
- | ^
-
- This is because the union field internalvar::u is not initialized when
- constructing the temporary internalvar object above. That object is then used
- for move-construction, and the (implicit) move constructor copies the
- uninitialized bytes of field u over from the temporary object to the new
- internalvar object. The compiler therefore complains that we use uninitialized
- bytes. I don't think it's really a problem, because the internalvar object is
- in the `kind == INTERNALVAR_VOID` state, in which the contents of the union is
- irrelevant. Still, mute the warning by default-initializing the union.

- [gdb/symtab] Add set/show always-read-ctf on/off
- [ This is a simplified rewrite of an earlier submission "[RFC][gdb/symtab] Add
- maint set symbol-read-order", submitted here (
- https://sourceware.org/pipermail/gdb-patches/2022-September/192044.html
- ). ]
-
- With the test-case included in this patch, we run into:
- ...
- (gdb) file dwarf2-and-ctf
- (gdb) print var_ctf^M
- 'var_ctf' has unknown type; cast it to its declared type^M
- ...
-
- The problem is that the executable contains both ctf and dwarf2, so the ctf
- info (which contains the type information about var_ctf) is ignored.
-
- GDB has support for handling multiple debug formats, but the common use case
- for ctf is to be used when dwarf2 is not present, and gdb reflects that,
- assuming that by reading ctf in addition there won't be any extra information,
- so it's not worth the additional cycles and memory.
-
- Add a new command "set/show always-read-ctf on/off", that when on forces
- unconditional reading of ctf, allowing us to do:
- ...
- (gdb) set always-read-ctf on
- (gdb) file dwarf2-and-ctf
- (gdb) print var_ctf^M
- $2 = 2^M
- ...
-
- The setting is off by default, preserving current behaviour.
-
- A bit of background on the relevance of reading order: the formats have a
- priority relationship between them, where reading earlier means lower
- priority. By reading the format with the most detail last, we ensure it has
- the highest priority, which makes sure that in case there is overlapping info,
- the most detailed info is found. This explains the current reading order of
- mdebug, stabs and dwarf2.
-
- Add the unconditional reading of ctf before dwarf2, because it's less detailed
- than dwarf2. The conditional reading of ctf is still done after the attempt to
- read dwarf2, necessarily so because we only know whether there's dwarf2 after
- we've tried to read it.
-
- The new command allow us to replace uses of -Wl,--strip-debug added in commit
- 908a926ec4e ("[gdb/testsuite] Fix ctf test-cases on openSUSE Tumbleweed") by
- uses of "set always-read-ctf on", but I've left that for another commit.

- gdb: add HtabPrinter to gdb-gdb.py.in
- When debugging GDB, I find it a bit tedious to inspect htab_t objects.
- It is possible to find the entries by poking at the fields, but it's
- annoying to do each time. I think a pretty printer would help. Add a

- The pretty printer advertises itself as "array-like", and the result

-
- The htab_t itself doesn't know about the type of pointed objects. But
- it's easy enough to cast the addresses to the right type to use them:
-
- (top-gdb) print *((btrace_frame_cache *) 0x6210003252a0)
- $6 = {tp = 0x61700002ed80, frame = 0x6210003251e0, bfun = 0x62000000b390}

- gdb: fix mi breakpoint-deleted notifications for thread-specific b/p
- Background
- ----------
-
- When a thread-specific breakpoint is deleted as a result of the
- specific thread exiting the function remove_threaded_breakpoints is
- called which sets the disposition of the breakpoint to
- disp_del_at_next_stop and sets the breakpoint number to 0. Setting
- the breakpoint number to zero has the effect of hiding the breakpoint
- from the user. We also print a message indicating that the breakpoint
- has been deleted.
-
- It was brought to my attention during a review of another patch[1]
- that setting a breakpoints number to zero will suppress the MI
- breakpoint-deleted notification for that breakpoint, and indeed, this
- can be seen to be true, in delete_breakpoint, if the breakpoint number
- is zero, then GDB will not notify the breakpoint_deleted observer.
-
- It seems wrong that a user created, thread-specific breakpoint, will
- have a =breakpoint-created notification, but will not have a
- =breakpoint-deleted notification. I suspect that this is a bug.
-
- [1] https://sourceware.org/pipermail/gdb-patches/2023-February/196560.html
-
- The First Problem
- -----------------
-
- During my initial testing I wanted to see how GDB handled the
- breakpoint after it's number was set to zero. To do this I created
- the testcase gdb.threads/thread-bp-deleted.exp. This test creates a
- worker thread, which immediately exits. After the worker thread has
- exited the main thread spins in a loop.
-
- In GDB I break once the worker thread has been created and place a
- thread-specific breakpoint, then use 'continue&' to resume the
- inferior in non-stop mode. The worker thread then exits, but the main
- thread never stops - instead it sits in the spin. I then tried to use
- 'maint info breakpoints' to see what GDB thought of the
- thread-specific breakpoint.
-
- Unfortunately, GDB crashed like this:
-
- (gdb) continue&
- Continuing.
- (gdb) [Thread 0x7ffff7c5d700 (LWP 1202458) exited]
- Thread-specific breakpoint 3 deleted - thread 2 no longer in the thread list.
- maint info breakpoints
- ... snip some output ...

- ... etc ...
-
- As the thread-specific breakpoint is set to disp_del_at_next_stop, and
- GDB hasn't stopped yet, then the breakpoint still exists in the global
- breakpoint list.
-
- The breakpoint will not show in 'info breakpoints' as its number is
- zero, but it will show in 'maint info breakpoints'.
-
- As GDB prints the breakpoint, the thread-id for the breakpoint is
- printed as part of the 'stop only in thread ...' line. Printing the
- thread-id involves calling find_thread_global_id to convert the global
- thread-id into a thread_info*. Then calling print_thread_id to
- convert the thread_info* into a string.
-
- The problem is that find_thread_global_id returns nullptr as the
- thread for the thread-specific breakpoint has exited. The
- print_thread_id assumes it will be passed a non-nullptr. As a result
- GDB crashes.
-
- In this commit I've added an assert to print_thread_id (gdb/thread.c)
- to check that the pointed passed in is not nullptr. This assert would
- have triggered in the above case before GDB crashed.
-
- MI Notifications: The Dangers Of Changing A Breakpoint's Number
- ---------------------------------------------------------------
-
- Currently the delete_breakpoint function doesn't trigger the
- breakpoint_deleted observer for any breakpoint with the number zero.
-
- There is a comment explaining why this is the case in the code; it's
- something about watchpoints. But I did consider just removing the 'is
- the number zero' guard and always triggering the breakpoint_deleted
- observer, figuring that I'd then fix the watchpoint issue some other
- way.
-
- But I realised this wasn't going to be good enough. When the MI
- notification was delivered the number would be zero, so any frontend
- parsing the notifications would not be able to match
- =breakpoint-deleted notification to the earlier =breakpoint-created
- notification.
-
- What this means is that, at the point the breakpoint_deleted observer
- is called, the breakpoint's number must be correct.
-
- MI Notifications: The Dangers Of Delaying Deletion
- --------------------------------------------------
-
- The test I used to expose the above crash also brought another problem
- to my attention. In the above test we used 'continue&' to resume,
- after which a thread exited, but the inferior didn't stop. Recreating
- the same test in the MI looks like this:
-
- -break-insert -p 2 main
- ^done,bkpt={number="2",type="breakpoint",disp="keep",...<snip>...}
- (gdb)
- -exec-continue
- ^running
- *running,thread-id="all"
- (gdb)
- ~"[Thread 0x7ffff7c5d700 (LWP 987038) exited]\n"
- =thread-exited,id="2",group-id="i1"
- ~"Thread-specific breakpoint 2 deleted - thread 2 no longer in the thread list.\n"
-
- At this point the we have a single thread left, which is still
- running:
-
- -thread-info
- ^done,threads=[{id="1",target-id="Thread 0x7ffff7c5eb80 (LWP 987035)",name="thread-bp-delet",state="running",core="4"}],current-thread-id="1"
- (gdb)
-
- Notice that we got the =thread-exited notification from GDB as soon as
- the thread exited. We also saw the CLI line from GDB, the line
- explaining that breakpoint 2 was deleted. But, as expected, we didn't
- see the =breakpoint-deleted notification.
-
- I say "as expected" because the number was set to zero. But, even if
- the number was not set to zero we still wouldn't see the
- notification. The MI notification is driven by the breakpoint_deleted
- observer, which is only called when we actually delete the breakpoint,
- which is only done the next time GDB stops.
-
- Now, maybe this is fine. The notification is delivered a little
- late. But remember, by setting the number to zero the breakpoint will
- be hidden from the user, for example, the breakpoint is removed from
- the MI's -break-info command output.
-
- This means that GDB is in a position where the breakpoint doesn't show
- up in the breakpoint table, but a =breakpoint-deleted notification has
- not yet been sent out. This doesn't seem right to me.
-
- What this means is that, when the thread exits, we should immediately
- be sending out the =breakpoint-deleted notification. We should not
- wait for GDB to next stop before sending the notification.
-
- The Solution
- ------------
-
- My proposed solution is this; in remove_threaded_breakpoints, instead
- of setting the disposition to disp_del_at_next_stop and setting the
- number to zero, we now just call delete_breakpoint directly.
-
- The notification will now be sent out immediately; as soon as the

-
- As the number has not changed when delete_breakpoint is called, the

-
- And as the breakpoint is immediately removed from the breakpoint list,
- we no longer need to worry about 'maint info breakpoints' trying to
- print the thread-id for an exited thread.
-
- My only concern is that calling delete_breakpoint directly seems so
- obvious that I wonder why the original patch (that added
- remove_threaded_breakpoints) didn't take this approach. This code was
- added in commit 49fa26b0411d, but the commit message offers no clues
- to why this approach was taken, and the original email thread offers
- no insights either[2]. There are no test regressions after making
- this change, so I'm hopeful that this is going to be fine.

-
- The Complication
- ----------------
-
- Of course, it couldn't be that simple.
-
- The script gdb.python/py-finish-breakpoint.exp had some regressions
- during testing.
-
- The problem was with the FinishBreakpoint.out_of_scope callback
- implementation. This callback is supposed to trigger whenever the
- FinishBreakpoint goes out of scope; and this includes when the thread
- for the breakpoint exits.
-
- The problem I ran into is the Python FinishBreakpoint implementation.
- Specifically, after this change I was loosing some of the out_of_scope
- calls.
-
- The problem is that the out_of_scope call (of which I'm interested) is
- triggered from the inferior_exit observer. Before my change the
- observers were called in this order:
-
- thread_exit
- inferior_exit
- breakpoint_deleted
-
- The inferior_exit would trigger the out_of_scope call.
-
- After my change the breakpoint_deleted notification (for
- thread-specific breakpoints) occurs earlier, as soon as the
- thread-exits, so now the order is:
-
- thread_exit
- breakpoint_deleted
- inferior_exit
-
- Currently, after the breakpoint_deleted call the Python object
- associated with the breakpoint is released, so, when we get to the
- inferior_exit observer, there's no longer a Python object to call the
- out_of_scope method on.
-
- My solution is to follow the model for how bpfinishpy_pre_stop_hook
- and bpfinishpy_post_stop_hook are called, this is done from
- gdbpy_breakpoint_cond_says_stop in py-breakpoint.c.
-
- I've now added a new bpfinishpy_pre_delete_hook
- gdbpy_breakpoint_deleted in py-breakpoint.c, and from this new hook
- function I check and where needed call the out_of_scope method.
-
- With this fix in place I now see the
- gdb.python/py-finish-breakpoint.exp test fully passing again.
-
- Testing
- -------
-
- Tested on x86-64/Linux with unix, native-gdbserver, and
- native-extended-gdbserver boards.
-
- New tests added to covers all the cases I've discussed above.

- gdb/testsuite: fix failure in gdb.mi/mi-pending.exp with extended-remote
- I currently see this failure when running the gdb.mi/mi-pending.exp

- (gdb)
- FAIL: gdb.mi/mi-pending.exp: MI pending breakpoint on mi-pendshr.c:pendfunc2 if x==4 (unexpected output)
-
- The failure is caused by the 'evaluated-by="host"' string, which only
- appears in the output when the test is run using the
- native-extended-remote board.
-
- I could fix this by just updating the pattern in
- gdb.mi/mi-pending.exp, but I have instead updated mi-pending.exp to
- make more use of the support procs in mi-support.exp. This did
- require making a couple of adjustments to mi-support.exp, but I think
- the result is that mi-pending.exp is now easier to read, and I see no
- failures with native-extended-remote anymore.
-
- One of the test names has changed after this work, I think the old
- test name was wrong - it described a breakpoint as pending when the
- breakpoint was not pending, I suspect a copy & paste error.
-
- But there's no changes to what is actually being tested after this
- patch.

- Introduce foreach_mi_ui_mode, a helper proc which can be used when

- gdb: don't duplicate 'thread' field in MI breakpoint output
- When creating a thread-specific breakpoint with a single location, the
- 'thread' field would be repeated in the MI output. This can be seen
- in two existing tests gdb.mi/mi-nsmoribund.exp and
- gdb.mi/mi-pending.exp, e.g.:
-
- (gdb)
- -break-insert -p 1 bar

- times="0",original-location="bar"}
-
- I know we need to be careful when adjusting MI output, but I'm hopeful
- in this case, as the field is duplicated, and the field contents are
- always identical, that we might get away with removing one of the
- duplicates.
-
- The change in GDB is a fairly trivial condition change.
-
- We did have a couple of tests that contained the duplicate fields in

- this oddity either in the GDB code, or in the test, I suspect this was
- more a case of copying whatever output GDB produced and using that as
- the expected results. I've updated these tests to remove the
- duplication.
-
- I've update lib/mi-support.exp to provide support for building
- breakpoint patterns that contain the thread field, and I've made use
- of this in a new test I've added that is just about creating
- thread-specific breakpoints and checking the results. The two tests I
- mentioned above as being updated could also use the new
- lib/mi-support.exp functionality, but I'm going to do that in a later
- patch, this way it is clear what changes I'm actually proposing to
- make to the expected output.
-
- As I said, I hope that frontends will be able to handle this change,

- Forced quit cases handled by resetting sync_quit_force_run
- During my audit of the use of gdb_exception with regard to QUIT
- processing, I found a try/catch in the scoped_switch_fork_info
- destructor.
-
- Static analysis found this call path from the destructor to
- maybe_quit():
-
- scoped_switch_fork_info::~scoped_switch_fork_info()
- -> remove_breakpoints()
- -> remove_breakpoint(bp_location*)
- -> remove_breakpoint_1(bp_location*, remove_bp_reason)
- -> memory_validate_breakpoint(gdbarch*, bp_target_info*)
- -> target_read_memory(unsigned long, unsigned char*, long)
- -> target_read(target_ops*, target_object, char const*, unsigned char*, unsigned long, long)
- -> maybe_quit()
-
- Since it's not safe to do a 'throw' from a destructor, we simply
- call set_quit_flag and, for gdb_exception_forced_quit, also
- set sync_quit_force_run. This will cause the appropriate
- exception to be rethrown at the next QUIT check.
-
- Another case is the try / catch in tui_getc() in tui-io.c. The
- existing catch swallows the exception. I've added a catch for
- 'gdb_exception_forced_quit', which also swallows the exception,
- but also sets sync_quit_force_run and calls set_quit_flag in
- order to restart forced quit processing at the next QUIT check.
- This is required because it isn't safe to throw into/through
- readline.
-
- Thanks to Pedro Alves for suggesting this idea.

- QUIT processing w/ explicit throw for gdb_exception_forced_quit
- This commit contains changes which have an explicit throw for
- gdb_exception_forced_quit, or, in a couple of cases for gdb_exception,
- but with a throw following a check to see if 'reason' is
- RETURN_FORCED_QUIT.
-
- Most of these are straightforward - it made sense to continue to allow
- an existing catch of gdb_exception to also catch gdb_exception_quit;
- in these cases, a catch/throw for gdb_exception_forced_quit was added.
-
- There are two cases, however, which deserve a more detailed
- explanation.
-
- 1) remote_fileio_request in gdb/remote-fileio.c:
-
- The try block calls do_remote_fileio_request which can (in turn)
- call one of the functions in remote_fio_func_map[]. Taking the
- first one, remote_fileio_func_open(), we have the following call
- path to maybe_quit():
-
- remote_fileio_func_open(remote_target*, char*)
- -> target_read_memory(unsigned long, unsigned char*, long)
- -> target_read(target_ops*, target_object, char const*, unsigned char*, unsigned long, long)
- -> maybe_quit()
-
- Since there is a path to maybe_quit(), we must ensure that the
- catch block is not permitted to swallow a QUIT representing a
- SIGTERM.
-
- However, for this case, we must take care not to change the way that
- Ctrl-C / SIGINT is handled; we want to send a suitable EINTR reply to
- the remote target should that happen. That being the case, I added a
- catch/throw for gdb_exception_forced_quit. I also did a bit of
- rewriting here, adding a catch for gdb_exception_quit in favor of
- checking the 'reason' code in the catch block for gdb_exception.
-
- 2) mi_execute_command in gdb/mi/mi-main.c:
-
- The try block calls captured_mi_execute_command(); there exists
- a call path to maybe_quit():
-
- captured_mi_execute_command(ui_out*, mi_parse*)
- -> mi_cmd_execute(mi_parse*)
- -> get_current_frame()
- -> get_prev_frame_always_1(frame_info*)
- -> frame_register_unwind_location(frame_info*, int, int*, lval_type*, unsigned long*, int*)
- -> frame_register_unwind(frame_info*, int, int*, int*, lval_type*, unsigned long*, int*, unsigned char*)
- -> value_entirely_available(value*)
- -> value_fetch_lazy(value*)
- -> value_fetch_lazy_memory(value*)
- -> read_value_memory(value*, long, int, unsigned long, unsigned char*, unsigned long)
- -> maybe_quit()
-
- That being the case, we can't allow the exception handler (catch block)
- to swallow a gdb_exception_quit for SIGTERM. However, it does seem
- reasonable to output the exception via the mi interface so that some
- suitable message regarding SIGTERM might be printed; therefore, I
- check the exception's 'reason' field for RETURN_FORCED_QUIT and
- do a throw for this case.

- Catch gdb_exception_error instead of gdb_exception (in many places)
- As described in the previous commit for this series, I became
- concerned that there might be instances in which a QUIT (due to either
- a SIGINT or SIGTERM) might not cause execution to return to the top
- level. In some (though very few) instances, it is okay to not
- propagate the exception for a Ctrl-C / SIGINT, but I don't think that
- it is ever okay to swallow the exception caused by a SIGTERM.
- Allowing that to happen would definitely be a deviation from the
- current behavior in which GDB exits upon receipt of a SIGTERM.
-
- I looked at all cases where an exception handler catches a
- gdb_exception. Handlers which did NOT need modification were those
- which satisifed one or more of the following conditions:
-
- 1) There is no call path to maybe_quit() in the try block. I used a
- static analysis tool to help make this determination. In
- instances where the tool didn't provide an answer of "yes, this
- call path can result in maybe_quit() being called", I reviewed it
- by hand.
-
- 2) The catch block contains a throw for conditions that it
- doesn't want to handle; these "not handled" conditions
- must include the quit exception and the new "forced quit" exception.
-
- 3) There was (also) a catch for gdb_exception_quit.
-
- Any try/catch blocks not meeting the above conditions could
- potentially swallow a QUIT exception.
-
- My first thought was to add catch blocks for gdb_exception_quit and
- then rethrow the exception. But Pedro pointed out that this can be
- handled without adding additional code by simply catching
- gdb_exception_error instead. That's what this patch series does.
-
- There are some oddball cases which needed to be handled differently,
- plus the extension languages, but those are handled in later patches.

- Handle gdb SIGTERM by throwing / catching gdb_exception_force_quit
- When a GDB process receives the SIGTERM signal, handle_sigterm() in
- event-top.c is called. The global variable 'sync_quit_force_run' is
- set by this signal handler. It does some other things too, but the
- setting of this global is the important bit for the SIGTERM part of
- this discussion.
-
- GDB will periodically check to see whether a Ctrl-C or SIGTERM has
- been received. This is performed via use of the QUIT macro in
- GDB's code. QUIT is defined to invoke maybe_quit(), which will be
- periodically called during any lengthy operation. This is supposed to
- ensure that the user won't have to wait too long for a Ctrl-C or
- SIGTERM to be acted upon.
-
- When a Ctrl-C / SIGINT is received, quit_handler() will decide whether
- to pass the SIGINT onto the inferior or to call quit() which causes
- gdb_exception_quit to be thrown. This exception (usually) propagates
- to the top level. Control is then returned to the top level event
- loop.
-
- At the moment, SIGTERM is handled very differently. Instead of
- throwing an exception, quit_force() is called. This does eventually
- cause GDB to exit(), but prior to that happening, the inferiors
- are killed or detached and other target related cleanup occurs.
- As shown in this discussion between Pedro Alves and myself...
-
- https://sourceware.org/pipermail/gdb-patches/2021-July/180802.html
- https://sourceware.org/pipermail/gdb-patches/2021-July/180902.html
- https://sourceware.org/pipermail/gdb-patches/2021-July/180903.html
-
- ...we found that it is possible for inferior_ptid and current_thread_
- to get out of sync. When that happens, the "current_thread_ != nullptr"
- assertion in inferior_thread() can fail resulting in a GDB internal
- error.
-
- Pedro recommended that we "let the normal quit exception propagate all
- the way to the top level, and then have the top level call quit_force
- if sync_quit_force_run is set." However, after the v2 series for this
- patch set, we tweaked that idea by introducing a new exception for
- handling SIGTERM.
-
- This commit implements the obvious part of Pedro's suggestion:
- Instead of calling quit_force from quit(), throw_forced_quit() is now
- called instead. This causes the new exception 'gdb_exception_forced_quit'
- to be thrown.
-
- At the top level, I changed catch_command_errors() and captured_main()
- to catch gdb_exception_forced_quit and then call quit_force() from the
- catch block. I also changed start_event_loop() to also catch
- gdb_exception_forced_quit; while we could also call quit_force() from
- that catch block, it's sufficient to simply rethrow the exception
- since it'll be caught by the newly added code in captured_main().
-
- Making these changes fixed the failure / regression that I was seeing
- for gdb.base/gdb-sigterm.exp when run on a machine with glibc-2.34.
- However, there are many other paths back to the top level which this
- test case does not test. I did an audit of all of the try / catch
- code in GDB in which calls in the try-block might (eventually) call
- QUIT. I found many cases where gdb_exception_quit and the new
- gdb_exception_forced_quit will be swallowed. (When using GDB, have
- you ever hit Ctrl-C and not have it do anything; if so, it could be
- due to a swallowed gdb_exception_quit in one of the cases I've
- identified.) The rest of the patches in this series deal with this
- concern.

- Introduce gdb_exception_forced_quit
- This commit adds a new exception 'gdb_exception_forced_quit', reason
- code 'REASON_FORCED_QUIT', return mask 'RETURN_MASK_FORCED_QUIT', and
- a wrapper for throwing the exception, throw_forced_quit().
-
- The addition of this exception plus supporting code will allow us to
- recognize that a SIGTERM has been received by GDB and then propagate
- recognition of that fact to the upper levels of GDB where it can be
- correctly handled. At the moment, when GDB receives a SIGTERM, it
- will attempt to exit via a series of calls from the QUIT checking
- code. However, before it can exit, it must do various cleanups, such
- as killing or detaching all inferiors. Should these cleanups be
- attempted while GDB is executing very low level code, such as reading
- target memory from within ps_xfer_memory(), it can happen that some of
- GDB's state is out of sync with regard to the cleanup code's
- expectations. In the case just mentioned, it's been observed that
- inferior_ptid and the current_thread_ are not in sync; this triggers
- an assert / internal error.
-
- This commit only introduces the exception plus supporting machinery;
- changes which use this new exception are in later commits in this
- series.

- Fix value chain use-after-free
- Hannes filed a bug showing a crash, where a pretty-printer written in
- Python could cause a use-after-free. He sent a patch, but I thought a
- different approach was needed.
-
- In a much earlier patch (see bug #12533), we changed the Python code
- to release new values from the value chain when constructing a
- gdb.Value. The rationale for this is that if you write a command that
- does a lot of computations in a loop, all the values will be kept live
- by the value chain, resulting in gdb using a large amount of memory.
-
- However, suppose a value is passed to Python from some code in gdb
- that needs to use the value after the call into Python. In this
- scenario, value_to_value_object will still release the value -- and
- because gdb code doesn't generally keep strong references to values (a
- consequence of the ancient decision to use the value chain to avoid
- memory management), this will result in a use-after-free.
-
- This scenario can happen, as it turns out, when a value is passed to
- Python for pretty-printing. Now, normally this route boxes the value
- via value_to_value_object_no_release, avoiding the problematic release
- from the value chain. However, if you then call Value.cast, the
- underlying value API might return the same value, when is then
- released from the chain.
-
- This patch fixes the problem by changing how value boxing is done.
- value_to_value_object no longer removes a value from the chain.
- Instead, every spot in gdb that might construct new values uses a
- scoped_value_mark to ensure that the requirements of bug #12533 are
- met. And, because incoming values aren't ever released from the chain
- (the Value.cast one comes earlier on the chain than the
- scoped_value_mark), the bug can no longer occur. (Note that many
- spots in the Python layer already take this approach, so not many
- places needed to be touched.)
-
- In the future I think we should replace the use of raw "value *" with
- value_ref_ptr pretty much everywhere. This will ensure lifetime
- safety throughout gdb.
-
- The test case in this patch comes from Hannes' original patch. I only
- made a trivial ("require") change to it. However, while this fails
- for him, I can't make it fail on this machine; nevertheless, he tried
- my patch and reported the bug as being fixed.

- all-stop "follow-fork parent" and selecting another thread
- With:
-
- - catch a fork in thread 1
- - select thread 2
- - set follow-fork child
- - next
-
- ... follow_fork notices that thread 1 had last stopped for a fork
- which hasn't been followed yet, and because thread 1 is not the
- current thread, GDB aborts the execution command, presenting the stop
- in thread 1.
-
- That makes sense, as only the forking thread (thread 1) survives in
- the child, so better stop and let the user decide how to proceed.
-
- However, with:
-
- - catch a fork in thread 1
- - select thread 2
- - set follow-fork parent << note difference here
- - next
-
- ... GDB does the same: follow_fork notices that thread 1 had last
- stopped for a fork which hasn't been followed yet, and because thread
- 1 is not the current thread, GDB aborts the execution command,
- presenting the stop in thread 1.
-
- Aborting/stopping in this case doesn't make sense to me. As we're
- following the parent, thread 2 will still continue to exist in the
- parent. What the child does after we've followed the parent shouldn't
- matter -- it can go on running free, be detached, etc., depending on
- "set schedule-multiple", "set detach-on-fork", etc. That does not
- influence the execution command that the user issued for the parent
- thread.
-
- So this patch changes GDB in that direction -- in follow_fork, if
- following the parent, and we've switched threads meanwhile, switch
- back to the unfollowed thread, follow it (stay with the parent), and
- don't abort/stop. If we're following a fork (as opposed to vfork),
- then switch back again to the thread that the user was trying to
- resume. If following a vfork, however, stay with the vforking-thread
- selected, as we will need to see a vfork_done event first, before we
- can resume any other thread.
-
- As I was working on this, I managed to end up calling target_resume
- for a solo-thread resume (to collect the vfork_done event), with
- scope_ptid pointing at the vfork parent thread, and inferior_ptid
- pointing to the vfork child. For a solo-thread resume, the scope_ptid
- argument to target_resume must the same as inferior_ptid. The mistake
- was caught by the assertion in target_resume, like so:
-
- ...
- [infrun] resume_1: step=0, signal=GDB_SIGNAL_0, trap_expected=0, current thread [1722839.1722839.0] at 0x5555555553c3
- [infrun] do_target_resume: resume_ptid=1722839.1722939.0, step=0, sig=GDB_SIGNAL_0
- ../../src/gdb/target.c:2661: internal-error: target_resume: Assertion `inferior_ptid.matches (scope_ptid)' failed.
- ...
-
- but I think it doesn't hurt to catch such a mistake earlier, hence the
- change in internal_resume_ptid.

-
- Make follow_fork not rely on get_last_target_status
- Currently, if
-
- - you're in all-stop mode,
- - the inferior last stopped because of a fork catchpoint,
-
- when you next resume the program, gdb checks whether it had last
- stopped for a fork/vfork, and if so,
-
- a) if the current thread is the one that forked, gdb follows the
- parent/child, depending on "set follow-fork" mode.
-
- b) if the current thread is some other thread (because you switched
- threads meanwhile), gdb switches back to that thread, gdb follows
- the parent/child, and stops the resumption command.
-
- There's a problem in b), however -- if you have "set schedule-multiple
- off", which is the default, or "set scheduler-locking on", gdb will
- still switch back to the forking thread, even if you didn't want to
- resume it. For example, with:
-
- (gdb) catch fork
- (gdb) c
- * thread 1 stops for fork
- (gdb) thread 2
- (gdb) set scheduler-locking on
- (gdb) c
-
- gdb switches back to thread 1, and follows the fork.
-
- Or with:
-
- (gdb) add-inferior -exec prog
- (gdb) inferior 2
- (gdb) start
- (gdb) inferior 1
- (gdb) catch fork
- (gdb) c
- * thread 1.1 stops for fork
- (gdb) inferior 2
- (gdb) set schedule-multiple off # this is the default
- (gdb) c
-
- gdb switches back to thread 1.1, and follows the fork.
-
- Another issue is that, because follow_fork relies on
- get_last_target_status to find the thread that has a pending fork, it
- is possible to confuse it. For example, "run" or "start" call
- init_wait_for_inferior, which clears the last target status, so this:
-
- (gdb) catch fork
- (gdb) c
- * thread 1 stops for fork
- (gdb) add-inferior -exec prog
- (gdb) inferior 2
- (gdb) start
- (gdb) set follow-fork child
- (gdb) inferior 1
- (gdb) n
-
- ... does not follow to the fork child of inferior 1, because the
- get_last_target_status call in follow_fork doesn't return a
- TARGET_WAITKIND_FORKED. Thanks to Simon for this example.
-
- All of the above are fixed by this patch. It changes follow_fork to
- not look at get_last_target_status, but to instead iterate over the
- set of threads that the user is resuming, and find the one that has a
- pending_follow kind of fork/vfork.
-
- gdb.base/foll-fork.exp is augmented to exercise the last "start"
- scenario described above. The other cases will be exercised in the

- Improve "info program"
- With gdb.base/catch-follow-exec.exp, we currently see:
-
- ~~~~~~~~~~~~~~~
- (gdb)
- continue
- Continuing.
- process 693251 is executing new program: /usr/bin/ls
- [New inferior 2]
- [New process 693251]
- [Switching to process 693251]
-
- Thread 2.1 "ls" hit Catchpoint 2 (exec'd /usr/bin/ls), 0x00007ffff7fd0100 in _start () from /lib64/ld-linux-x86-64.so.2
- (gdb)
- info prog
- No selected thread.
- ~~~~~~~~~~~~~~~
-
- Note the "No selected thread" output. That is totally bogus, because
- there _is_ a selected thread. What GDB really means, is that it can't
- find the thread that had the latest (user-visible) stop. And that
- happens because "info program" gets that info from
- get_last_target_status, and the last target status has been cleared.
-
- However, GDB also checks if there is a selected thread, here:
-
- if (ptid == null_ptid || ptid == minus_one_ptid)
- error (_("No selected thread."));
-
- .. the null_ptid part. That is also bogus, because what matters is
- the thread that last reported a stop, not the current thread:
-
- - in all-stop mode, "info program" displays info about the last stop.
- That may have happened on a thread different from the selected
- thread.
-
- - in non-stop mode, because all threads are controlled individually,
- "info program" shows info about the last stop of the selected
- thread.
-
- The current code already behaves this way, though in a poor way. This
- patch reimplements it, such that the all-stop version now finds the
- thread that last reported an event via the 'previous_thread' strong
- reference. Being a strong reference means that if that thread has
- exited since the event was reported, 'previous_thread' will still
- point to it, so we can say that the thread exited meanwhile.
-
- The patch also extends "info program" output a little, to let the user
- know which thread we are printing info for. For example, for the
- gdb.base/catch-follow-exec.exp case we shown above, we now get:
-
- (gdb) info prog
- Last stopped for thread 2.1 (process 710867).
- Using the running image of child process 710867.
- Program stopped at 0x7ffff7fd0100.
- It stopped at breakpoint 2.
- Type "info stack" or "info registers" for more information.
- (gdb)
-
- while in non-stop mode, we get:
-
- (gdb) info prog
- Selected thread 2.1 (process 710867).
- Using the running image of child process 710867.
- Program stopped at 0x7ffff7fd0100.
- It stopped at breakpoint 2.
- Type "info stack" or "info registers" for more information.
- (gdb)
-
- In both cases, the first line of output is new.
-
- The existing code considered these running/exited cases as an error,
- but I think that that's incorrect, since this is IMO just plain
- execution info as well. So the patch makes those cases regular
- prints, not errors.
-
- If the thread is running, we get, in non-stop mode:
-
- (gdb) info prog
- Selected thread 2.1 (process 710867).
- Selected thread is running.
-
- ... and in all-stop:
-
- (gdb) info prog
- Last stopped for thread 2.1 (process 710867).
- Thread is now running.
-
- If the thread has exited, we get, in non-stop mode:
-
- (gdb) info prog
- Selected thread 2.1 (process 710867).
- Selected thread has exited.
-
- ... and in all-stop:
-
- (gdb) info prog
- Last stopped for thread 2.1 (process 710867).
- Thread has since exited.
-
- The gdb.base/info-program.exp testcase was much extended to test
- all-stop/non-stop and single-threaded/multi-threaded.

-
- Convert previous_inferior_ptid to strong reference to thread_info
- I originally wrote this patch, because while working on some other
- patch, I spotted a regression in the
- gdb.multi/multi-target-no-resumed.exp.exp testcase. Debugging the
- issue, I realized that the problem was related to how I was using
- previous_inferior_ptid to look up the thread the user had last
- selected. The problem is that previous_inferior_ptid alone doesn't
- tell you which target that ptid is from, and I was just always using
- the current target, which was incorrect. Two different targets may
- have threads with the same ptid.
-
- I decided to fix this by replacing previous_inferior_ptid with a
- strong reference to the thread, called previous_thread.
-
- I have since found a new motivation for this change -- I would like to
- tweak "info program" to not rely on get_last_target_status returning a
- ptid that still exists in the thread list. With both the follow_fork
- changes later in this series, and the step-over-thread-exit changes,
- that can happen, as we'll delete threads and not clear the last
- waitstatus.
-
- A new update_previous_thread function is added that can be used to
- update previous_thread from inferior_ptid. This must be called in
- several places that really want to get rid of previous_thread thread,
- and reset the thread id counter, otherwise we get regressions like
- these:

- analysis (which I find really helpful) doesn't work. I therefore think
- it would be better to spell out the parameters.

- gdb: remove invalid / dead code from gdbarch.py
- My editor flagged that the variable `c` (in the lines removed by this
- patch) was unknown. I guess it ends up working because there is a `c`
- variable in the global scope. I tried putting `assert False` inside
- that if, and it is not hit, showing that we never enter this if. So,
- remove it. There is no change in the generated files.

- Fix crash with "finish" in Rust
- PR rust/30090 points out that a certain "finish" in a Rust program
- will cause gdb to crash. This happens due to some confusion about
- field indices in rust_language::print_enum. The fix is to use
- value_primitive_field so that the correct type can be passed; other
- spots in rust-lang.c already do this.
-
- Note that the enclosed test case comes with an xfail. This is needed
- because for this function, rustc doesn't follow the platform ABI.

- Handle range types in ax-gdb.c
- A range type can usually be treated the same as its underlying integer
- type, at least for the purposes of agent expressions. This patch

- Implement some agent expressions for Ada
- Ada historically has not implemented agent expressions, and some Ada
- constructs probably cannot reasonably be converted to agent
- expressions. However, a subset of simple operations can be, and this
- patch represents a first step in that direction.
-
- On one internal AdaCore test case, this improves the performance of a
- conditional breakpoint from 5 minutes to 5 seconds.
-
- The main tricky part in this patch is ensuring the converted
- expressions detect the cases that will not work. This is done by
- examining the code in the corresponding evaluation methods.

- Regenerate Linux syscall group info
- This commit makes use of the new script to regenerate the Linux
- syscall group info against strace git hash
- e88e5e9ae6da68f22d15f9be3193b1412ac9aa02.
-
- Like so:
-
- $ cd gdb/syscalls/
- $ ./update-linux-defaults.sh ~/strace.git/
- Generating linux-defaults.xml.in
- $ make
- for f in aarch64-linux.xml amd64-linux.xml arm-linux.xml bfin-linux.xml \
- i386-linux.xml mips-n32-linux.xml mips-n64-linux.xml \
- mips-o32-linux.xml ppc64-linux.xml ppc-linux.xml s390-linux.xml \
- s390x-linux.xml sparc64-linux.xml sparc-linux.xml; do \
- xsltproc --output $f apply-defaults.xsl $f.in; \
- done
-
- The result is that a lot more syscalls end up assigned to groups.
- Some lose their group info, but that just mirrors what strace does.
-
- The gdb/syscalls/linux-defaults.xml.in file shows a large diff because
- the new version is ASCII sorted, while the current version was
- somewhat (but not consistently) sorted by "family" of syscalls.
-
- If I sort the old file and diff against the new, the difference is

- Autogenerate gdb/syscalls/linux-defaults.xml.in (groups) from strace sources
- I noticed that "catch syscall group:process" doesn't catch clone3,
- while it does catch clone.
-
- The catch syscall group information is recorded in the
- gdb/syscalls/linux-defaults.xml.in file, which says:
-
- <!-- The group field information was based on strace. -->
-
- So I looked at the strace sources, to confirm that clone3 is in fact
- recorded in the "process" group there too, and to check what other
- syscalls might be missing groups.
-
- After some digging, I found that strace records the group info in C
- arrays, with entries like:
- ...
- [ 61] = { 4, TP, SEN(wait4), "wait4" },
- [ 62] = { 2, TS|TP, SEN(kill), "kill" },
- [ 63] = { 1, 0, SEN(uname), "uname" },
- ...
-
- You can see the current master's table for Linux x86-64 here:
-
- https://github.com/strace/strace/blob/e88e5e9ae6da68f22d15f9be3193b1412ac9aa02/src/linux/x86_64/syscallent.h
-
- The column with TS|TP above is what defines each syscall's groups. So
- I wrote a script that extracts this information and generates
- linux-defaults.xml.in.

- gdb: don't treat empty enums as flag enums
- In C++ it is possible to use an empty enum as a strong typedef. For
- example, a user could write:
-
- enum class my_type : unsigned char {};
-
- Now my_type can be used like 'unsigned char' except the compiler will
- not allow implicit conversion too and from the native 'unsigned char'
- type.
-
- This is used in the standard library for things like std::byte.
-
- Currently, when GDB prints a value of type my_type, it looks like
- this:
-
- (gdb) print my_var
- $1 = (unknown: 0x4)
-
- Which isn't great. This gets worse when we consider something like:
-
- std::vector<my_type> vec;
-
- When using a pretty-printer, this could look like this:
-
- std::vector of length 2, capacity 2 = {(unknown: 0x2), (unknown: 0x4)}
-
- Clearly not great. This is described in PR gdb/30148.
-
- The problem here is in dwarf2/read.c, we assume all enums are flag
- enums unless we find an enumerator with a non-flag like value.
- Clearly an empty enum contains no non-flag values, so we assume the
- enum is a flag enum.
-
- I propose adding an extra check here; that is, an empty enum should
- never be a flag enum.
-
- With this the above cases look more like:
-
- (gdb) print my_var
- $1 = 4
-
- and:
-
- std::vector of length 2, capacity 2 = {2, 4}
-
- Which look much better.

- gdb/testsuite: Improve testing of GDB's completion functions
- When looking at some failures of gdb.linespec/cp-completion-aliases.exp,
- I noticed that when a completion test will fail, it always fails with a
- timeout. This is because most completion tests use gdb_test_multiple
- and only add a check for the correct output. This commit adds new
- options for both, tab and command completion.
-
- For command completion, the new option will check if the prompt was
- printed, and fail in this case. This is enough to know that the test has
- failed because the check comes after the PASS path. For tab completion,
- we have to check if GDB outputted more than just the input line, because
- sometimes GDB would have printed a partial line before finishing with
- the correct completion.

- Remove struct buffer
- I've long wanted to remove 'struct buffer', and thanks to Simon's
- earlier patch, I was finally able to do so. My feeling has been that
- gdb already has several decent structures available for growing
- strings: std::string of course, but also obstack and even objalloc
- from BFD and dyn-string from libiberty. The previous patches in this
- series removed all the uses of struct buffer, so this one can remove
- the code and the remaining #includes.
-
- Don't use struct buffer in top.c
- This changes top.c to use std::string rather than struct buffer. Like
- the event-top.c change, this is not completely ideal in that it
- requires a copy of the string.

- Write the DWARF index in the background
- The new DWARF cooked indexer interacts poorly with the DWARF index
- cache. In particular, the cache will require gdb to wait for the
- cooked index to be finalized. As this happens in the foreground, it
- means that users with this setting enabled will see a slowdown.
-
- This patch changes gdb to write the cache entry a worker thread. (As
- usual, in the absence of threads, this work is simply done immediately
- in the main thread.)
-
- Some care is taken to ensure that this can't crash, and that gdb will
- not exit before the task is complete.
-
- To avoid use-after-free problems, the DWARF per-BFD object explicitly
- waits for the index cache task to complete.
-
- To avoid gdb exiting early, an exit observer is used to wait for all
- such pending tasks.
-
- In normal use, neither of these waits will be very visible. For users
- using "-batch" to pre-generate the index, though, it would be.
- However I don't think there is much to be done about this, as it was
- the status quo ante.
-
-2023-02-24 Tom Tromey <tromey@adacore.com>
-
- Only use the per-BFD object to write a DWARF index
- The DWARF index does not need access to the objfile or per-objfile
- objects when writing -- it's entirely based on the objfile-independent
- per-BFD data.
-
- This patch implements this idea by changing the entire API to only be
- passed the per-BFD object. This simplifies some lifetime reasoning
- for the next patch.
-
- This patch removes some code that ensures that the BFD came from a
- file. It seems to me that checking for the existence of a build-id is
- good enough for the index cache.

- x86: allow to request ModR/M encoding
- Several insns have a (typically shorter) non-ModR/M and a (typically
- longer) ModR/M encoding. In most cases the former is used by default.
- This isn't too dissimilar from register-only insns sometimes having two
- encoding forms. In those cases {load} or {store} can be used to control
- the encoding used. Extend this to ModR/M-less encodings which have a
- ModR/M counterpart (note that BSWAP hasn't). For insn reading and
- writing their (explicit) memory operand, both prefixes are honored;
- otherwise only the applicable one is.
-
- Note that for some forms of XCHG, {store} has already been performing
- this function, apparently as an unnoticed side effect of adding D to
- the template.

-
- x86: restrict insn templates accepting negative 8-bit immediates
- For shifts (but not ordinary rotates) and other cases where an immediate
- describes e.g. a bit count or position, allowing negative operands is at
- best confusing. An extreme example would be the two rotate-through-carry
- insns, where a negative value would _not_ mean rotating the
- corresponding number of bits in the other direction. To refuse such,
- give meaning to the combination of Imm8 and Imm8S in templates (so far
- these weren't used together anywhere). The issue was with
- smallest_imm_type() blindly setting .imm8 for signed numbers determined
- to fit in a byte.
-
- VPROT{B,W,D,Q} is a little special: The rotate count there is a signed
- quantity, so Imm8 is replaced by Imm8S. Adjust affected testcases
- accordingly as well.
-
- Another small adjustment to the testsuite is necessary: AAM and AAD were
- never sensible to use with 0xffffff90 operands. This should have been an
- error.

- gdb: remove --disable-gdbmi configure option
- I noticed that the --disable-gdbmi option was broken for almost a year
- (since 740b42ceb7c "gdb/python/mi: create MI commands using python").
-
- The problem today is the python/py-cmd.c file. It is included in the
- build if Python support is enabled, and it calls into some MI functions
- (e.g. insert_mi_cmd_entry). If MI support is disabled, we get some
- undefined symbols like:
-
- mold: error: undefined symbol: insert_mi_cmd_entry(std::unique_ptr<mi_command, std::default_delete<mi_command> >)
- >>> referenced by py-micmd.c
- >>> python/py-micmd.o:(micmdpy_install_command(micmdpy_object*))
-
- The python/py-cmd.c file should be included in the build if both Python
- and MI support are enabled. It is not a case we support today, but it
- could be done with a bit more configure code. However, I think we
- should just remove the --disable-gdbmi option, and just include MI
- support unconditionally.
-
- Tom Tromey proposed a while ago to remove this option, but it ended
- staying:
-
- https://inbox.sourceware.org/gdb-patches/20180628172132.28843-1-tom@tromey.com/
-
- However, there was no strong opposition to remove it. The argument was
- just "bah, it doesn't hurt anybody".
-
- But given today's case, I would rather remove complexity rather than add
- some. I couldn't find anybody caring deeply for that option, and it's
- not like MI adds any external dependency. It's just a bit more code.
-
- Removing the option will not break anybody using --disable-gdbmi (it can
- be found in many build scripts [1]), since we don't flag invalid
- configure flags.
-
- So, remove the option from configure.ac, and adjust Makefile.in
- accordingly to always include the MI objects in the build.

- gdb.reverse/time-reverse.exp: test both time syscall and C time function
- Instead of only testing this on systems that have a SYS_time syscall,
- test it everywhere using the time(2) C function, and in addition, run
- the tests again using the SYS_time syscall.
-
- The C variant ensures that if some platform uses some syscall we are
- not aware of yet, we'll still exercise it, and likely fail, at which
- point we should teach GDB about the syscall.
-
- The explicit syscall variant is useful on platforms where the C
- function does not call a syscall at all by default, e.g., on some
- systems the C time function wraps an implementation provided by the
- vDSO.

- x86-64: LAR and LSL don't need REX.W
- Just like we suppress emitting REX.W for e.g. MOV from/to segment
- register, there's also no need for it for LAR and LSL - these can only
- ever return 32-bit values and hence always zero-extend their results
- anyway.

- Re: objdump read_section_stabs
- Commit f9c36cc99518 changed (and renamed) read_section_stabs with one
- difference in overall behaviour. Previously read_section_stabs would
- return a NULL for an empty section, which was then treated the same as
- a missing section. Now an empty section is recognized and dumped.
- This leads to NULL stabp and stabs_end in print_section_stabs. Since
- stabs_end - STABSIZE is then a pointer to a very large address, the
- test "stabp < stabs_end - STABSIZE" succeeds.
-
- * objdump.c (print_section_stabs): Correct STABSIZE comparison.

- gdb: add --with-curses to --configuration output
- 'gdb --configuration' does not mention if GDB was built with curses.
- Since b5075fb68d4 (Rename to allow_tui_tests, 2023-01-08) it does show
- --enable-tui (or --disable-tui), but one might want to know if GDB was
- built with curses independently of the availability of the TUI.
-
- Since configure.ac uses AC_SEARCH_LIBS to check for the curses library,
- we do not get an automatically defined HAVE_LIBCURSES symbol in
- config.in. We do have symbols defined by AC_CHECK_HEADERS
- (HAVE_CURSES_H, etc.) but it would be cumbersome to use those in
- print_gdb_configuration because we would have to check for all 6 symbols
- corresponding the 6 headers listed. This would also increase the
- maintenance burden if support for other variations of curses are added.
-
- Instead, define 'HAVE_LIBCURSES' ourselves by adding an
- 'action-if-found' argument to AC_SEARCH_LIBS, and use it in
- print_gdb_configuration.
-
- While at it, remove the condition on 'ac_cv_search_waddstr' and set
- 'curses_found' directly in 'action-if-found'.

- [aarch64] Enable pointer authentication support for aarch64 bare metal/kernel mode addresses
- At the moment GDB only handles pointer authentication (pauth) for userspace
- addresses and if we're debugging a Linux-hosted program.
-
- The Linux Kernel can be configured to use pauth instructions for some
- additional security hardening, but GDB doesn't handle this well.
-
- To overcome this limitation, GDB needs a couple things:
-
- 1 - The target needs to advertise pauth support.
- 2 - The hook to remove non-address bits from a pointer needs to be registered
- in aarch64-tdep.c as opposed to aarch64-linux-tdep.c.
-
- There is a patch for QEMU that addresses the first point, and it makes
- QEMU's gdbstub expose a couple more pauth mask registers, so overall we will
- have up to 4 pauth masks (2 masks or 4 masks):
-
- pauth_dmask
- pauth_cmask
- pauth_dmask_high
- pauth_cmask_high
-
- pauth_dmask and pauth_cmask are the masks used to remove pauth signatures
- from userspace addresses. pauth_dmask_high and pauth_cmask_high masks are used
- to remove pauth signatures from kernel addresses.
-
- The second point is easily addressed by moving code around.
-
- When debugging a Linux Kernel built with pauth with an unpatched GDB, we get
- the following backtrace:
-
- #0 __fput (file=0xffff0000c17a6400) at /repos/linux/fs/file_table.c:296
- #1 0xffff8000082bd1f0 in ____fput (work=<optimized out>) at /repos/linux/fs/file_table.c:348

- #3 0x30d48000080ade30 in ?? ()
- Backtrace stopped: previous frame identical to this frame (corrupt stack?)
-
- With a patched GDB, we get something a lot more meaningful:
-
- #0 __fput (file=0xffff0000c1bcfa00) at /repos/linux/fs/file_table.c:296
- #1 0xffff8000082bd1f0 in ____fput (work=<optimized out>) at /repos/linux/fs/file_table.c:348

-
- 1. Each MI command is introduced like this:

-
- Except for a few of the tracing command, which just use:

-
- In this commit I've updated all these trace commands to use the
- more common format.
-
- 2. Each MI command starts with a @subheading, and then the details
- of that command are split up using multiple @subsubheading
- entries.
-
- Except for a few commands which use @subheading for the top-level
- command, and then continue to use @subheading for each part of
- the command description.
-
- In this commit I've updated these to use @subsubheading where
- appropriate.

- For a -g0 -fasynchronous-unwind-tables exec (without .debug_info but with
- .eh_frame section), start using the dwarf2 unwinder instead of the
- "amd64 epilogue override" unwinder, by returning true in
- compunit_epilogue_unwind_valid for cust == nullptr.
-
- This has effect both on the amd64 and i386 targets, but only add amd64
- test-case gdb.base/unwind-on-each-insn-amd64-2.exp.
-
-2023-02-20 Tom de Vries <tdevries@suse.de>
-
- [gdb/tdep] Add amd64/i386 epilogue override unwinders
- For amd64 the current frame-unwinders are:
- ...
- $ gdb -q -batch -ex "set arch i386:x86-64" -ex "maint info frame-unwinders"
- The target architecture is set to "i386:x86-64".
- dummy DUMMY_FRAME
- dwarf2 tailcall TAILCALL_FRAME
- inline INLINE_FRAME
- python NORMAL_FRAME
- amd64 epilogue NORMAL_FRAME
- dwarf2 NORMAL_FRAME
- dwarf2 signal SIGTRAMP_FRAME
- amd64 sigtramp SIGTRAMP_FRAME
- amd64 prologue NORMAL_FRAME
- ...
-
- For a -g0 -fasynchronous-unwind-tables exec (without .debug_info but with
- .eh_frame section), we'd like to start using the dwarf2 unwinder instead of
- the "amd64 epilogue" unwinder, by returning true in
- compunit_epilogue_unwind_valid for cust == nullptr.
-
- But we'd run into the following problem for a -g0
- -fno-asynchronous-unwind-tables (without .debug_info and .eh_frame section)
- exec:
- - the "amd64 epilogue" unwinder would not run
- (because compunit_epilogue_unwind_valid () == true)
- - the dwarf2 unwinder would also not run
- (because there's no .eh_frame info).
-
- Fix this by:
- - renaming the "amd64 epilogue" unwinder to "amd64 epilogue override", and
- - adding a fallback "amd64 epilogue" after the dwarf unwinders,
- while making sure that only one of the two is active. Likewise for i386. NFC.
-
- For amd64, this results in this change:
- ...
- $ gdb -q -batch -ex "set arch i386:x86-64" -ex "maint info frame-unwinders"
- The target architecture is set to "i386:x86-64".

-
- And for i386:

- [gdb/testsuite] Fix gdb.threads/schedlock.exp for gcc 4.8.5
- Since commit 9af467b8240 ("[gdb/testsuite] Fix gdb.threads/schedlock.exp on
- fast cpu"), the test-case fails for gcc 4.8.5.
-
- The problem is that for gcc 4.8.5, the commit turned a two-line loop:
- ...
- (gdb) next
- 78 while (*myp > 0)
- (gdb) next
- 81 MAYBE_CALL_SOME_FUNCTION(); (*myp) ++;
- (gdb) next
- 78 while (*myp > 0)
- ...
- into a three-line loop:
- ...
- (gdb) next
- 83 MAYBE_CALL_SOME_FUNCTION(); (*myp) ++;
- (gdb) next
- 84 cnt++;
- (gdb) next
- 85 }
- (gdb) next
- 83 MAYBE_CALL_SOME_FUNCTION(); (*myp) ++;
- (gdb)
- ...
- and the test-case doesn't expect this.
-
- Fix this by reverting back to the original loop shape as much as possible by:
- - removing the cnt++ line
- - replacing "while (1)" with "while (one)", where one is a volatile variable
- set to 1.
-
- Tested on x86_64-linux, using compilers:
- - gcc 4.8.5, 7.5.0, 12.2.1
- - clang 4.0.1, 13.0.1

- Fix "start" for D, Rust, etc
- The new DWARF indexer broke "start" for some languages.
-
- For D, it is broken because, while the code in cooked_index_shard::add
- specifically excludes Ada, it fails to exclude D. This means that the
- C "main" will be detected as "main" here -- whereas what is intended
- is for the code in find_main_name to use d_main_name to find the name.
-
- The Rust compiler, on the other hand, uses DW_AT_main_subprogram.
- However, the code in dwarf2_build_psymtabs_hard fails to create a
- fully-qualified name, so the name always ends up as plain "main".
-
- For D and Ada, a very simple approach suffices: remove the check
- against "main" from cooked_index_shard::add. This also has the
- benefit of slightly speeding up DWARF indexing. I assume this
- approach will work for Pascal and Modula-2 as well, but I don't have a
- way to test those at present.
-
- For Rust, though, this is not sufficient. And, computing the
- fully-qualified name in dwarf2_build_psymtabs_hard will crash, because
- cooked_index_entry::full_name uses the canonical name -- and that is
- not computed until after canonicalization.
-
- However, we don't want to wait for canonicalization to be done before
- computing the main name. That would remove any benefit from doing
- canonicalization is the background.
-
- This patch solves this dilemma by noticing that languages using
- DW_AT_main_subprogram are, currently, disjoint from languages
- requiring canonicalization. Because of this, we can add a parameter
- to full_name to let us avoid crashes, slowdowns, and races here.
-
- This is kind of tricky and ugly, so I've tried to comment it
- sufficiently.
-
- While doing this, I had to change gdb.dwarf2/main-subprogram.exp. A
- different possibility here would be to ignore the canonicalization
- needs of C in this situation, because those only affect certain types.
- However, I chose this approach because the test case is artificial
- anyhow.
-
- A long time ago, in an earlier threading attempt, I changed the global
- current_language to be a function (hidden behind a macro) to let us
- attempt lazily computing the current language. Perhaps this approach
- could still be made to work. However, that also seemed rather tricky,
- more so than this patch.

- Fix multi-threaded debugging under AIX
- Multi-threaded debugging using the libpthdebug debug interface
- is currently broken due to multiple issues.
-
- When debugging a single inferior, we were getting assertion
- failures in get_aix_thread_info as no tp->priv structure was
- allocated for the main thread.
-
- We fixed this by switching the main
- thread from a (pid, 0, 0) ptid_t to a (pid, 0, tid) ptid_t and
- allocaing the tp->priv structure in sync_threadlists.
-
- As a result, the switch_to_thread call in pdc_read_data could
- now fail since the main thread no longer uses (pid, 0, 0).
-
- So we replaced the call by only switching inferior_ptid, the current
- inferior, and the current address space (like proc-service.c).
- Add similar switching to pdc_write_data where it was missing
- completely.
-
- When debugging multiple inferiors, an additional set of
- problems prevented correct multi-threaded debugging:
-
- First of all, aix-thread.c used to have a number of global
- variables holding per-inferior information.
-
- We switched hese
- to a per-inferior data structure instead.
-
- Also, sync_threadlists was getting confused as we were
- comparing the list of threads returned by libpthdebug
- for *one* process with GDB's list of threads for *all*
- processes. Now we only use he GDB threads of the current
- inferior instead.
-
- We also skip calling pd_activate
- from pd_enable if that in_initial_library_scan flag is
- true for the current inferior.
-
- Finally, the presence of the thread library in any but
- the first inferior was not correctly detected due to a
- bug in solib-aix.c, where the BFD file name for shared
- library members was changed when the library was loaded
- for the first time, which caused the library to no longer
- be recognized by name when loaded a second time.

- [gdb/testsuite] Simplify gdb.arch/amd64-disp-step-avx.exp

- var128 has expected value after

- (gdb) FAIL: gdb.arch/amd64-disp-step-avx.exp: \
- continue until exit at amd64-disp-step-avx
- ...
-
- This is not related to gdb, we get the same result by just running the exec.
-
- The problem is that the test-case:
- - calls glibc's _exit, and
- - uses -nostartfiles -static, putting the burden for any necessary
- initialization for calling glibc's _exit on the test-case itself.
-
- So, when we get to the second insn in _exit:
- ...
- 000000000040acb0 <_exit>:
- 40acb0: 48 63 d7 movslq %edi,%rdx
- 40acb3: 64 4c 8b 14 25 00 00 mov %fs:0x0,%r10
- ...
- no glibc-related initialization is done, and we run into the segfault.
-
- Adding this (borrowed from __libc_start_main) in _start in the .S file is
- sufficient to fix it:
- ...
- .rept 200
- nop
- + call __pthread_initialize_minimal
- .endr
- ...
- But that already doesn't compile with say glibc 2.31, and regardless I think
- this sort of fix is too fragile.
-
- We could of course fix this by simply not running to exit. But ideally we'd
- have an exec that doesn't segfault when you just run it.
-
- Alternatively, we could hand-code an _exit syscall and bypass glibc
- all together. But I'd rather fix this in a way that simplifies the test-case.
-
- Taking a step back, the -nostartfiles -static was added to address that the
- xmm registers were not zero at main (which AFAICT is a valid thing to happen).
-
- [ The change itself silently broke the test-case, needing further fixing by
- commit 40310f30a51 ("gdb: make gdb.arch/amd64-disp-step-avx.exp actually test
- displaced stepping"). ]
-
- Instead, simplify things by reverting to the original situation:
- - no -nostartfiles -static compilation flags,
- - no _start in the .S file,
- - use exit instead of _exit in the .S file,
- and fix the original problem by setting the xmm registers to zero rather than
- checking that they're zero.
-
- Now that we're no longer forcing -static, add nopie to the flags to prevent
- compilation failure with target board unix/-fPIE/-pie.
-
- Tested on x86_64-linux.

- x86/gas: replace inappropriate assertion when parsing registers
- PR gas/30117
- Once a symbol had its expression evaluated, the "segment" of the symbol
- may be reg_section if a register is merely involved in the expression,
- not just when the expression references a "plain" register. Therefore
- the first of the assertions put in place by 4d1bb7955a8b was too strict.
- Convert it to an if() to deal with situations like this one found by
- fuzzing:
-
- x=s
- s=%eax+0
- y=s
- or $6,x
-
- In non-debug builds this also avoids potentially silently generating bad
- code.

- Don't throw quit while handling inferior events, part II
- I noticed that if Ctrl-C was typed just while GDB is evaluating a
- breakpoint condition in the background, and GDB ends up reaching out
- to the Python interpreter, then the breakpoint condition would still
- fail, like:
-
- c&
- Continuing.
- (gdb) Error in testing breakpoint condition:
- Quit
-
- That happens because while evaluating the breakpoint condition, we
- enter Python, and end up calling PyErr_SetInterrupt (it's called by
- gdbpy_set_quit_flag, in frame #0):

-
- The fix is to disable cooperative SIGINT handling while handling
- inferior events, so that SIGINT is saved in the global quit flag, and
- not in the extension language, while handling an event.
-
- This commit augments the testcase added by the previous commit to test
- this scenario as well.

-
- Don't throw quit while handling inferior events
- This implements what I suggested here:
-
- https://inbox.sourceware.org/gdb-patches/ab97c553-f406-b094-cdf3-ba031fdea925@palves.net/
-
- Here is the current default quit_handler, a function that ends up
- called by the QUIT macro:
-
- void
- default_quit_handler (void)
- {
- if (check_quit_flag ())
- {
- if (target_terminal::is_ours ())
- quit ();
- else
- target_pass_ctrlc ();
- }
- }
-
- As we can see above, when the inferior is running in the foreground,
- then a Ctrl-C is translated into a call to target_pass_ctrlc().
-
- The target_terminal::is_ours() case above is there to handle the
- scenario where GDB has the terminal, meaning it is handling some
- command the user typed, like "list", or "p a + b" or some such.
-
- However, when the inferior is running on the background, say with
- "c&", GDB also has the terminal. Run control handling is now done in
- the "background". The CLI is responsive to user commands. If users
- type Ctrl-C, they're expecting it to interrupt whatever command they
- next type in the CLI, which again, could be "list", "p a + b", etc.
- It's as if background run control was handled by a separate thread,
- and the Ctrl-C is meant to go to the main thread, handling the CLI.
-
- However, when handling an event, inside fetch_inferior_event &
- friends, a Ctrl-C _also_ results in a Quit exception, from the same
- default_quit_handler function shown above. This quit aborts run
- control handling, breakpoint condition evaluation, etc., and may even
- leave run control in an inconsistent state.
-
- The testcase added by this patch illustrates this. The test program
- just loops a number of times calling the "foo" function.
-
- The idea is to set a breakpoint in the "foo" function with a condition
- that sends SIGINT to GDB, and then evaluates to false, which results
- in the program being re-resumed in the background. The SIGINT-sending
- emulates pressing Ctrl-C just while GDB was evaluating the breakpoint
- condition, except, it's more deterministic.
-
- It looks like this:
-
- (gdb) p $counter = 0
- $1 = 0
- (gdb) b foo if $counter++ == 10 || $_shell("kill -SIGINT `pidof gdb`") != 0
- Breakpoint 2 at 0x555555555131: file gdb.base/bg-exec-sigint-bp-cond.c, line 21.
- (gdb) c&
- Continuing.
- (gdb)
-
- After that background continue, the breakpoint should be hit 10 times,
- and we should see 10 "Quit" being printed on the screen. As if the
- user typed Ctrl-C on the prompt a number of times with no inferior
- running:
-
- (gdb) <<< Ctrl-C
- (gdb) Quit <<< Ctrl-C
- (gdb) Quit <<< Ctrl-C
- (gdb)
-
- However, here's what you see instead:
-
- (gdb) c&
- Continuing.
- (gdb) Quit
- (gdb)
-
- Just one Quit, and nothing else. If we look at the thread's state, we see:
-
- (gdb) info threads
- Id Target Id Frame
- * 1 Thread 0x7ffff7d6f740 (LWP 112192) "bg-exec-sigint-" foo () at gdb.base/bg-exec-sigint-bp-cond.c:21
-
- So the thread stopped, but we didn't report a stop...
-
- Issuing another continue shows the same immediate-and-silent-stop:
-
- (gdb) c&
- Continuing.
- (gdb) Quit
- (gdb) p $counter
- $2 = 2
-
- As mentioned, since the run control handling, and breakpoint and
- watchpoint evaluation, etc. are running in the background from the
- perspective of the CLI, when users type Ctrl-C in this situation,
- they're thinking of aborting whatever other command they were typing
- or running at the prompt, not the run control side, not the previous
- "c&" command.
-
- So I think that we should install a custom quit_handler while inside
- fetch_inferior_event, where we already disable pagination and other
- things for a similar reason. This custom quit handler does nothing if
- GDB has the terminal, and forwards Ctrl-C to the inferior otherwise.
-
- With the patch implementing that, and the same testcase, here's what
- you see instead:
-
- (gdb) p $counter = 0
- $1 = 0
- (gdb) b foo if $counter++ == 10 || $_shell("kill -SIGINT `pidof gdb`") != 0
- Breakpoint 2 at 0x555555555131: file gdb.base/bg-exec-sigint-bp-cond.c, line 21.
- (gdb) c&
- Continuing.
- (gdb) Quit
- (gdb) Quit
- (gdb) Quit
- (gdb) Quit
- (gdb) Quit
- (gdb) Quit
- (gdb) Quit
- (gdb) Quit
- (gdb) Quit
- (gdb) Quit
- (gdb)
- Breakpoint 2, foo () at gdb.base/bg-exec-sigint-bp-cond.c:21
- 21 return 0;

- Add new "$_shell(CMD)" internal function
- For testing a following patch, I wanted a way to send a SIGINT to GDB
- from a breakpoint condition. And I didn't want to do it from a Python
- breakpoint or Python function, as I wanted to exercise non-Python code
- paths. So I thought I'd add a new $_shell internal function, that
- runs a command under the shell, and returns the exit code. With this,
- I could write:
-
- (gdb) b foo if $_shell("kill -SIGINT $gdb_pid") != 0 || <other condition>
-
- I think this is generally useful, hence I'm proposing it here.
-
- Here's the new function in action:
-
- (gdb) p $_shell("true")
- $1 = 0
- (gdb) p $_shell("false")
- $2 = 1
- (gdb) p $_shell("echo hello")
- hello
- $3 = 0
- (gdb) p $_shell("foobar")
- bash: line 1: foobar: command not found
- $4 = 127
- (gdb) help function _shell
- $_shell - execute a shell command and returns the result.
- Usage: $_shell (command)
- Returns the command's exit code: zero on success, non-zero otherwise.
- (gdb)

- Make "ptype INTERNAL_FUNCTION" in Ada print like other languages
- Currently, printing the type of an internal function in Ada shows
- double <>s, like:
-
- (gdb) with language ada -- ptype $_isvoid
- type = <<internal function>>
-
- while all other languages print it with a single <>, like:
-
- (gdb) with language c -- ptype $_isvoid
- type = <internal function>
-
- I don't think there's a reason that Ada needs to be different. We
- currently print the double <>s because we take this path in
- ada_print_type:
-
- switch (type->code ())
- {
- default:
- gdb_printf (stream, "<");
- c_print_type (type, "", stream, show, level, language_ada, flags);
- gdb_printf (stream, ">");
- break;
-
- ... and the type's name already has the <>s.
-
- Fix this by simply adding an early check for
- TYPE_CODE_INTERNAL_FUNCTION.

-
- Fix "ptype INTERNAL_FUNC" (PR gdb/30105)
- Currently, looking at the type of an internal function, like below,
- hits an odd error:
-
- (gdb) ptype $_isvoid
- type = <internal function>type not handled in c_type_print_varspec_prefix()
-
- That is an error thrown from
- c-typeprint.c:c_type_print_varspec_prefix, where it reads:
-
- ...
- case TYPE_CODE_DECFLOAT:
- case TYPE_CODE_FIXED_POINT:
- /* These types need no prefix. They are listed here so that
- gcc -Wall will reveal any types that haven't been handled. */
- break;
- default:
- error (_("type not handled in c_type_print_varspec_prefix()"));
- break;
-
- Internal function types have type code TYPE_CODE_INTERNAL_FUNCTION,
- which is not explicitly handled by that switch.
-
- That comment quoted above says that gcc -Wall will reveal any types
- that haven't been handled, but that's not actually true, at least with
- modern GCCs. You would need to enable -Wswitch-enum for that, which
- we don't. If I do enable that warning, then I see that we're missing
- handling for the following type codes:
-
- TYPE_CODE_INTERNAL_FUNCTION,
- TYPE_CODE_MODULE,
- TYPE_CODE_NAMELIST,
- TYPE_CODE_XMETHOD
-
- TYPE_CODE_MODULE and TYPE_CODE_NAMELIST and Fortran-specific, so it'd
- be a little weird to handle them here.
-
- I tried to reach this code with TYPE_CODE_XMETHOD, but couldn't figure
- out how to. ptype on an xmethod isn't treated specially, it just
- complains that the method doesn't exist. I've extended the
- gdb.python/py-xmethods.exp testcase to make sure of that.
-
- My thinking is that whatever type code we add next, the most likely
- scenario is that it won't need any special handling, so we'd just be
- adding another case to that "do nothing" list. If we do need special
- casing for whatever type code, I think that tests added at the same
- time as the feature would uncover it anyhow. If we do miss adding the
- special casing, then it still looks better to me to print the type
- somewhat incompletely than to error out and make it harder for users
- to debug whatever they need. So I think that the best thing to do
- here is to just remove all those explicit "do nothing" cases, along
- with the error default case.
-
- After doing that, I decided to write a testcase that iterates over all
- supported languages doing "ptype INTERNAL_FUNC". That revealed that
- Pascal has a similar problem, except the default case hits a
- gdb_assert instead of an error:
-
- (gdb) with language pascal -- ptype $_isvoid
- type =
- ../../src/gdb/p-typeprint.c:268: internal-error: type_print_varspec_prefix: unexpected type
- A problem internal to GDB has been detected,
- further debugging may prove unreliable.
-
- That is fixed by this patch in the same way.
-
- You'll notice that the new testcase special-cases the Ada expected
- output:
-
- } elseif {$lang == "ada"} {
- gdb_test "ptype \$_isvoid" "<<internal function>>"
- } else {
- gdb_test "ptype \$_isvoid" "<internal function>"
- }
-
- That will be subject of the following patch.

-
- I managed to narrow it down to:
-
- $ ./gdb -nx -q --data-directory=data-directory testsuite/outputs/gdb.btrace/record_goto/record_goto -ex "start" -ex "record btrace" -ex "next"
-
- ... and then doing repeatedly "record goto 19" and "record goto 27".
- Eventually, I get:
-

- The problem is a stale entry in the bfcache hash table (in
- record-btrace.c), left across a reinit_frame_cache. This entry points
- to something that used to be allocated on the frame obstack, that has
- since been wiped by reinit_frame_cache.
-
- Before the aforementioned, unwinder deallocation functions were called
- by iterating on the frame chain, starting with the sentinel frame, like
- so:
-
- /* Tear down all frame caches. */
- for (frame_info *fi = sentinel_frame; fi != NULL; fi = fi->prev)
- {
- if (fi->prologue_cache && fi->unwind->dealloc_cache)
- fi->unwind->dealloc_cache (fi, fi->prologue_cache);
- if (fi->base_cache && fi->base->unwind->dealloc_cache)
- fi->base->unwind->dealloc_cache (fi, fi->base_cache);
- }
-
- After that patch, we relied on the fact that all frames are (supposedly)
- in the frame_stash. A deletion function was added to the frame_stash
- hash table, so that dealloc functions would be called when emptying the
- frame stash. There is one case, however, where a frame_info is not in
- the frame stash. That is when we create the frame_info for the current
- frame (level 0, unwound from the sentinel frame), but don't compute its
- frame id. The computation of the frame id for that frame (and only that
- frame, AFAIK) is done lazily. And putting a frame_info in the frame stash
- requires knowing its id. So a frame 0 whose frame id is not computed
- yet is necessarily not in the frame stash.
-
- When replaying with btrace, record_btrace_frame_sniffer insert entries
- corresponding to frames in the "bfcache" hash table. It then relies on
- record_btrace_frame_dealloc_cache being called for each frame to remove
- all those entries when the frames get invalidated. If a frame reinit
- happens while frame 0's id is not computed (and therefore that frame is
- not in frame_stash), record_btrace_frame_dealloc_cache does not get
- called for it, and it leaves a stale entry in bfcache. That then leads
- to a use-after-free when that entry is accessed later, which ASan
- catches.
-
- The proposed solution is to explicitly call frame_info_del on frame 0,
- if it exists, and if its frame id is not computed. If its frame id is
- computed, it is expected that it will be in the frame stash, so it will
- be "deleted" through that.

- Remove RETURNS from BFD chew comments
- When reading the BFD manual, I noticed text like this:
-
- -- Function: bool bfd_close (bfd *abfd);
- Close a BFD. If the BFD was open for writing, then pending
- operations are completed and the file written out and closed. If
- ...
- *Returns*
- 'TRUE' is returned if all is ok, otherwise 'FALSE'.
-
- The *Returns*, like the *Synopsis* in the earlier patch, is
- un-info-like. It's also used inconsistently.
-
- This patch removes all the uses of the RETURNS word and removes it
- entirely from the chew scripts. Now this example reads:
-
- -- Function: bool bfd_close (bfd *abfd);
- Close a BFD. If the BFD was open for writing, then pending
- operations are completed and the file written out and closed. If
- ...
- 'TRUE' is returned if all is ok, otherwise 'FALSE'.
-
- In a few cases I had to slightly reword the comment. There were also
- a couple of cases where there was redundant text. In these cases I
- just dropped the RETURNS copy.

- Use @deftypefn in chew output
- When reading the BFD info manual, function definitions looked very
- strange to me:
-
- *Synopsis*
- long bfd_get_mtime (bfd *abfd);
- *Description*
- Return the file modification time (as read from the file system, or from
- the archive header for archive members).
-
- The *Synopsis* and *Description* text in particular is very un-info-like.
-
- To fix this, I tried removing the *Synopsis* text and having FUNCTION
- use @deftypefn instead. However, this ended up requiring some new
- state, because SYNOPSIS can appear without FUNCTION. This in turn
- required "catstrif" (I considered adding FORTH-style if-else-then, but
- in the end decided on an ad hoc approach).
-
- After this the result looks like:
-
- -- Function: long bfd_get_mtime (bfd *abfd);
- Return the file modification time (as read from the file system, or
- from the archive header for archive members).
-
- This patch also reorders a few documentation comments to ensure that
- SYNOPSIS comes before DESCRIPTION. This is the more common style and
- is also now required by doc.str.

- gdb: store internalvars in an std::map
- In a test downstream in ROCgdb, we had a test case failing when
- GDB_REVERSE_INIT_FUNCTIONS was set. The test was assuming a particular
- order in the output of "show convenience". And the order changes when
- running with GDB_REVERSE_INIT_FUNCTIONS.
-
- I think that a nice way to fix it is to make the output of "show
- convenience" sorted, and therefore stable. Ideally, I think that the
- the user-visible behavior of GDB should not change when using
- GDB_REVERSE_INIT_FUNCTIONS. Plus, it makes the output of "show
- convenience" look nice, not that it's really important.
-
- Implement this by storing the internal vars in an std::map, which is a
- sorted container.

- Do not record a rejected target description
- When connecting to a certain target, gdb issues a warning about the
- target description:
-
- (gdb) target remote localhost:7947
- Remote debugging using localhost:7947
- warning: Architecture rejected target-supplied description
-
- If you then kill the inferior and change the exec-file, this will
- happen:
-
- (gdb) file bar
- Architecture of file not recognized.
-
- After this, debugging doesn't work very well.
-
- What happens here is that, despite the warning,
- target_find_description records the downloaded description in the
- target_desc_info. Then the "file" command ends up calling
- set_gdbarch_from_file, which uses that description.
-
- It seems to me that, because the architecture rejected the
- description, it should not be used. That is what this patch
- implements.

- gdb/manual: Move @findex entries
- The manual currently has many cases like these:
-
- @item $_gdb_setting_str (@var{setting})
- @findex $_gdb_setting_str@r{, convenience function}
-
- As suggested by Eli, move the @findex entries before @item so that the
- index records the position of @item, and the Info reader places you
- there when you use index-search.
-
- I went over all @findex calls in the manual, and most are like the
- above. Most either appear before @item, or before @subheading, like:
-
- @subheading The @code{-break-after} Command
- @findex -break-after
-
- I fixed all of them.
-
- There are findex entries in annotate.texinfo,python.texi, and
- stabs.texinfo as well, though those all look right to me already.
-
- Tested by typing "i _isvoid" (@item case) and "i -complete"
- (@subheading case) in an Info reader, and checking where those took

- Casting away const like this is bad. This patch removes the const and

- buffer directly to agent_run_command.

- [gdb/testsuite] Add xfail in gdb.python/py-record-btrace.exp
- There's a HW bug affecting Processor Trace on some Intel processors
- (Ice Lake to Raptor Lake microarchitectures).
-
- The bug was exposed by linux kernel commit 670638477aed
- ("perf/x86/intel/pt: Opportunistically use single range output mode"),
- added in version v5.5.0, and was worked around by commit ce0d998be927
- ("perf/x86/intel/pt: Fix sampling using single range output") in version
- 6.1.0.
-
- The bug manifests (on a Performance-core of an i7-1250U, an Alder Lake cpu) in
- a single test-case:
- ...
- (gdb) python insn = r.instruction_history^M
- warning: Decode error (-20) at instruction 33 (offset = 0x3d6a, \
- pc = 0x400501): compressed return without call.^M
- (gdb) FAIL: gdb.python/py-record-btrace.exp: prepare record: \
- python insn = r.instruction_history
- ...
-
- Add a corresponding XFAIL.
-
- Note that the i7-1250U has both Performance-cores and Efficient-cores, and on
- an Efficient-Core the test-case runs without any problems, so if the testsuite
- run is not pinned to a specific cpu, the test may either PASS or XFAIL.
-
- Tested on x86_64-linux:
- - openSUSE Leap 15.4 with linux kernel version 5.14.21
- - openSUSE Tumbleweed with linux kernel version 6.1.8

- gas: improve interaction between read_a_source_file() and s_linefile()
- read_a_source_file() would bump line numbers only when seeing a newline,
- whereas is_end_of_line[] indicates further end-of-line characters, in
- particular the nul character. s_linefile() attempts to compensate for
- the bump, but was too aggressive with this so far: It should only adjust
- when a newline ends the line. To facilitate such a check, the check for
- nothing else on the line needs to move ahead, which luckily is easily
- possible: The relevant two conditions match, and the function can
- simply return from the body of that earlier instance of the conditional.
-
- The more strict treatment in s_linefile() then requires an adjustment
- to buffer_and_nest()'s invocation of the function: The line terminator
- now needs to be a newline, not nul.

- gdb/python: deallocate tui window factories at Python shut down
- The previous commit relied on spotting when a Python defined TUI
- window factory was deleted. I spotted that the window factories are
- not deleted when GDB shuts down its Python environment, they are only
- deleted when one window factory replaces another. Consider this
- example Python script:
-
- class TestWindowFactory:
- def __init__(self, msg):
- self.msg = msg
- print("Entering TestWindowFactory.__init__: %s" % self.msg)
-
- def __call__(self, tui_win):
- print("Entering TestWindowFactory.__call__: %s" % self.msg)
- return TestWindow(tui_win, self.msg)
-
- def __del__(self):
- print("Entering TestWindowFactory.__del__: %s" % self.msg)
-
- gdb.register_window_type("test_window", TestWindowFactory("A"))
- gdb.register_window_type("test_window", TestWindowFactory("B"))
-
- And this GDB session:
-
- (gdb) source tui.py
- Entering TestWindowFactory.__init__: A
- Entering TestWindowFactory.__init__: B
- Entering TestWindowFactory.__del__: B
- (gdb) quit
-
- Notice that when the 'B' window replaces the 'A' window we see the 'A'
- object being deleted. But, when Python is shut down (after the
- 'quit') the 'B' object is never deleted.
-
- Instead, GDB retains a reference to the window factory object, which
- forces the Python object to remain live even after the Python
- interpreter itself has been shut down.
-
- The references themselves are held in a dynamically allocated
- std::unordered_map (in tui/tui-layout.c) which is never deallocated,
- thus the underlying Python references are never decremented to zero,
- and so GDB never tries to delete these Python objects.
-
- This commit is the first half of the work to clean up this edge case.
-
- All gdbpy_tui_window_maker objects (the objects that implement the
- TUI window factory callback for Python defined TUI windows), are now
- linked together into a global list using the intrusive list mechanism.
-
- When GDB shuts down the Python interpreter we can now walk this global
- list and release the reference that is held to the underlying Python
- object. By releasing this reference the Python object will now be
- deleted.
-
- I've added a new assert in gdbpy_tui_window_maker::operator(), this
- will catch the case where we somehow end up in here after having
- reset the reference to the underlying Python object. I don't think
- this should ever happen though as we only clear the references when
- shutting down the Python interpreter, and the ::operator() function is
- only called when trying to apply a new TUI layout - something that
- shouldn't happen while GDB itself is shutting down.
-
- This commit does not update the std::unordered_map in tui-layout.c,
- that will be done in the next commit.

- gdb.register_window_type('my_window', FactoryFunction)
-
- Then GDB would have a new TUI window 'my_window', which could be
- created by calling FactoryFunction(). If I then, in the same GDB
- session imported a script which included:
-
- gdb.register_window_type('my_window', UpdatedFactoryFunction)
-
- Then GDB would replace the old 'my_window' factory with my new one,
- GDB would now call UpdatedFactoryFunction().
-
- This is pretty useful in practice, as it allows users to iterate on
- their window implementation within a single GDB session.
-
- However, right now, this is not how GDB operates. The second call to
- register_window_type is basically ignored and the old window factory
- is retained.
-
- This is because in tui_register_window (tui/tui-layout.c) we use
- std::unordered_map::emplace to insert the new factory function, and
- emplace doesn't replace an existing element in an unordered_map.
-
- In this commit, before the emplace call, I now search for an already
- existing element, and delete any matching element from the map, the
- emplace call will then add the new factory function.

- Fix doc build dependencies for --with-system-readline
- PR build/30108 concerns building gdb documentation with
- --with-sytem-readline. If the in-tree readline directory is
- missing, though, the docs will fail to build:
-
- make[4]: Entering directory '/home/keiths/work/readline-doc-issue/linux/gdb/doc'
- make[4]: *** No rule to make target '../../../src/gdb/doc/../../readline/readline/doc/rluser.texi', needed by 'gdb.info'. Stop.
-
- The listed file (and hsuser.texi) are conditionally included by gdb.texinfo.
- When system readline is used, gdb/configure.ac will leave
- READLINE_TEXI_INCFLAGS empty, causing doc/Makefile.in to output a line to
- $BUILD/doc/GDBvn.texi with "@set SYSTEM_READLINE". This surpresses the
- inclusion of the missing files. They are not needed or used in this
- scenario.
-
- However, GDB_DOC_SOURCE_INCLUDES always lists these two files as dependencies,
- thus provoking the build error whenever readline/ is missing.
-
- This patch fixes this by creating (essentially) a conditional setting of the
- dependencies to be included from readline.

- gdb/testsuite: allow_hipcc_tests tests the hipcc compiler
- Update allow_hipcc_tests so all gdb.rocm tests are skipped if we do not
- have a working hipcc compiler available.
-
- To achieve this, adjust gdb_simple_compile to ensure that the hip
- program is saved in a ".cpp" file before calling hipcc otherwise
- compilation will fail.
-
- One thing to note is that it is possible to have a hipcc installed with
- a CUDA backend. Compiling with this back-end will successfully result
- in an application, but GDB cannot debug it (at least for the offload
- part). In the context of the gdb.rocm tests, we want to detect such
- situation where gdb_simple_compile would give a false positive.
-
- To achieve this, this patch checks that there is at least one AMDGPU
- device available and that hipcc can compile for this or those targets.
- Detecting the device is done using the rocm_agent_enumerator tool which
- is installed with the all ROCm installations (it is used by hipcc to
- detect identify targets if this is not specified on the comand line).
-
- This patch also makes the allow_hipcc_tests proc a cached proc.

- gdb/c++: fix handling of breakpoints on @plt symbols
- This commit should fix PR gdb/20091, PR gdb/17201, and PR gdb/17071.
- Additionally, PR gdb/17199 relates to this area of code, but is more
- of a request to refactor some parts of GDB, this commit does not
- address that request, but it is probably worth reading that PR when
- looking at this commit.
-
- When the current language is C++, and the user places a breakpoint on
- a function in a shared library, GDB will currently find two locations
- for the breakpoint, one location will be within the function itself as
- we would expect, but the other location will be within the PLT table
- for the call to the named function. Consider this session:
-
- $ gdb -q /tmp/breakpoint-shlib-func
- Reading symbols from /tmp/breakpoint-shlib-func...
- (gdb) start
- Temporary breakpoint 1 at 0x40112e: file /tmp/breakpoint-shlib-func.cc, line 20.
- Starting program: /tmp/breakpoint-shlib-func
-
- Temporary breakpoint 1, main () at /tmp/breakpoint-shlib-func.cc:20
- 20 int answer = foo ();
- (gdb) break foo
- Breakpoint 2 at 0x401030 (2 locations)
- (gdb) info breakpoints
- Num Type Disp Enb Address What
- 2 breakpoint keep y <MULTIPLE>
- 2.1 y 0x0000000000401030 <foo()@plt>
- 2.2 y 0x00007ffff7fc50fd in foo() at /tmp/breakpoint-shlib-func-lib.cc:20
-
- This is not the expected behaviour. If we compile the same test using
- a C compiler then we see this:
-
- (gdb) break foo
- Breakpoint 2 at 0x7ffff7fc50fd: file /tmp/breakpoint-shlib-func-c-lib.c, line 20.
- (gdb) info breakpoints
- Num Type Disp Enb Address What
- 2 breakpoint keep y 0x00007ffff7fc50fd in foo at /tmp/breakpoint-shlib-func-c-lib.c:20
-
- Here's what's happening. When GDB parses the symbols in the main
- executable and the shared library we see a number of different symbols
- for foo, and use these to create entries in GDB's msymbol table:
-
- - In the main executable we see a symbol 'foo@plt' that points at
- the plt entry for foo, from this we add two entries into GDB's
- msymbol table, one called 'foo@plt' which points at the plt entry
- and has type mst_text, then we create a second symbol, this time
- called 'foo' with type mst_solib_trampoline which also points at
- the plt entry,
-
- - Then, when the shared library is loaded we see another symbol
- called 'foo', this one points at the actual implementation in the
- shared library. This time GDB creates a msymbol called 'foo' with
- type mst_text that points at the implementation.
-
- This means that GDB creates 3 msymbols to represent the 2 symbols
- found in the executable and shared library.
-
- When the user creates a breakpoint on 'foo' GDB eventually ends up in
- search_minsyms_for_name (linespec.c), this function then calls
- iterate_over_minimal_symbols passing in the name we are looking for
- wrapped in a lookup_name_info object.
-
- In iterate_over_minimal_symbols we iterate over two hash tables (using
- the name we're looking for as the hash key), first we walk the hash
- table of symbol linkage names, then we walk the hash table of
- demangled symbol names.
-
- When the language is C++ the symbols for 'foo' will all have been
- mangled, as a result, in this case, the iteration of the linkage name
- hash table will find no matching results.
-
- However, when we walk the demangled hash table we do find some
- results. In order to match symbol names, GDB obtains a symbol name
- matching function by calling the get_symbol_name_matcher method on the
- language_defn class. For C++, in this case, the matching function we
- use is cp_fq_symbol_name_matches, which delegates the work to
- strncmp_iw_with_mode with mode strncmp_iw_mode::MATCH_PARAMS and
- language set to language_cplus.
-
- The strncmp_iw_mode::MATCH_PARAMS mode means that strncmp_iw_mode will
- skip any parameters in the demangled symbol name when checking for a
- match, e.g. 'foo' will match the demangled name 'foo()'. The way this
- is done is that the strings are matched character by character, but,
- once the string we are looking for ('foo' here) is exhausted, if we
- are looking at '(' then we consider the match a success.
-
- Lets consider the 3 symbols GDB created. If the function declaration
- is 'void foo ()' then from the main executable we added symbols
- '_Z3foov@plt' and '_Z3foov', while from the shared library we added
- another symbol call '_Z3foov'. When these are demangled they become
- 'foo()@plt', 'foo()', and 'foo()' respectively.
-
- Now, the '_Z3foov' symbol from the main executable has the type
- mst_solib_trampoline, and in search_minsyms_for_name, we search for
- any symbols of type mst_solib_trampoline and filter these out of the
- results.
-
- However, the '_Z3foov@plt' symbol (from the main executable), and the
- '_Z3foov' symbol (from the shared library) both have type mst_text.
-
- During the demangled name matching, due to the use of MATCH_PARAMS
- mode, we stop the comparison as soon as we hit a '(' in the demangled
- name. And so, '_Z3foov@plt', which demangles to 'foo()@plt' matches
- 'foo', and '_Z3foov', which demangles to 'foo()' also matches 'foo'.
-
- By contrast, for C, there are no demangled hash table entries to be
- iterated over (in iterate_over_minimal_symbols), we only consider the
- linkage name symbols which are 'foo@plt' and 'foo'. The plain 'foo'
- symbol obviously matches when we are looking for 'foo', but in this
- case the 'foo@plt' will not match due to the '@plt' suffix.
-
- And so, when the user asks for a breakpoint in 'foo', and the language
- is C, search_minsyms_for_name, returns a single msymbol, the mst_text
- symbol for foo in the shared library, while, when the language is C++,
- we get two results, '_Z3foov' for the shared library function, and
- '_Z3foov@plt' for the plt entry in the main executable.
-
- I propose to fix this in strncmp_iw_with_mode. When the mode is
- MATCH_PARAMS, instead of stopping at a '(' and assuming the match is a
- success, GDB will instead search forward for the matching, closing,
- ')', effectively skipping the parameter list, and then resume
- matching. Thus, when comparing 'foo' to 'foo()@plt' GDB will
- effectively compare against 'foo@plt' (skipping the parameter list),
- and the match will fail, just as it does when the language is C.
-
- There is one slight complication, which is revealed by the test
- gdb.linespec/cpcompletion.exp, when searching for the symbol of a
- const member function, the demangled symbol will have 'const' at the
- end of its name, e.g.:
-
- struct_with_const_overload::const_overload_fn() const
-
- Previously, the matching would stop at the '(' character, but after my
- change the whole '()' is skipped, and the match resumes. As a result,
- the 'const' modifier results in a failure to match, when previously
- GDB would have found a match.
-
- To work around this issue, in strncmp_iw_with_mode, when mode is
- MATCH_PARAMS, after skipping the parameter list, if the next character
- is '@' then we assume we are looking at something like '@plt' and
- return a value indicating the match failed, otherwise, we return a
- value indicating the match succeeded, this allows things like 'const'
- to be skipped.
-
- With these changes in place I now see GDB correctly setting a
- breakpoint only at the implementation of 'foo' in the shared library.

- gdb: use -1 for breakpoint::task default value
- Within the breakpoint struct we have two fields ::thread and ::task
- which are used for thread or task specific breakpoints. When a
- breakpoint doesn't have a specific thread or task then these fields
- have the values -1 and 0 respectively.
-
- There's no particular reason (as far as I can tell) why these two
- "default" values are different, and I find the difference a little
- confusing. Long term I'd like to potentially fold these two fields
- into a single field, but that isn't what this commit does.
-
- What this commit does is switch to using -1 as the "default" value for
- both fields, this means that the default for breakpoint::task has
- changed from 0 to -1. I've updated all the code I can find that
- relied on the value of 0, and I see no test regressions, especially in
- gdb.ada/tasks.exp, which still fully passes.
-
- There should be no user visible changes after this commit.

- gdb: only allow one of thread or task on breakpoints or watchpoints
- After this mailing list posting:
-
- https://sourceware.org/pipermail/gdb-patches/2023-February/196607.html
-
- it seems to me that in practice an Ada task maps 1:1 with a GDB
- thread, and so it doesn't really make sense to allow uses to give both
- a thread and a task within a single breakpoint or watchpoint
- condition.
-
- This commit updates GDB so that the user will get an error if both
- are specified.
-
- I've added new tests to cover the CLI as well as the Python and Guile
- APIs. For the Python and Guile testing, as far as I can tell, this
- was the first testing for this corner of the APIs, so I ended up
- adding more than just a single test.
-
- For documentation I've added a NEWS entry, but I've not added anything
- to the docs themselves. Currently we document the commands with a
- thread-id or task-id as distinct command, e.g.:
-
- 'break LOCSPEC task TASKNO'
- 'break LOCSPEC task TASKNO if ...'
- 'break LOCSPEC thread THREAD-ID'
- 'break LOCSPEC thread THREAD-ID if ...'
-
- As such, I don't believe there is any indication that combining 'task'
- and 'thread' would be expected to work; it seems clear to me in the
- above that those four options are all distinct commands.
-
- I think the NEWS entry is enough that if someone is combining these
- keywords (it's not clear what the expected behaviour would be in this
- case) then they can figure out that this was a deliberate change in
- GDB, but for a new user, the manual doesn't suggest combining them is
- OK, and any future attempt to combine them will give an error.

- ---------------------
-
- I recreated the above crash by a little light hacking on GDB, and then
- linking GDB against readline 5.2. The above stack trace was generated
- from the test included in this patch, and matches the trace that was
- included in the original bug report.
-
- It is worth acknowledging that without hacking things GDB has a
- minimum requirement of readline 7.0. This test is not about checking
- whether GDB has been built against an older version of readline, it is
- about checking that readline doesn't regress in this area.

- gdb: remove unnecessary 'dir' commands from gdb-gdb.gdb script
- While debugging GDB I used 'show directories' and spotted lots of
- entries that didn't make much sense. Here are all the entries that are
- in my directories list:
-
- /tmp/binutils-gdb/build
- /tmp/binutils-gdb/build/../../src/gdb
- /tmp/binutils-gdb/build/../../src/gdb/../bfd
- /tmp/binutils-gdb/build/../../src/gdb/../libiberty
- $cdir
- $cwd
-
- Notice the second, third, and fourth entries in this list, these
- should really be:
-
- /tmp/binutils-gdb/build/../src/gdb
- /tmp/binutils-gdb/build/../src/gdb/../bfd
- /tmp/binutils-gdb/build/../src/gdb/../libiberty
-
- The problem is because I generally run everything from the top level
- build directory, not the gdb/ sub-directory, thus, I start GDB like:
-
- ./gdb/gdb --data-directory ./gdb/data-directory
-
- If run GDB under GDB, then I end up loading the gdb/gdb-gdb.gdb
- script, which contains these lines:
-
- dir ../../src/gdb/../libiberty
- dir ../../src/gdb/../bfd
- dir ../../src/gdb
- dir .
-
- These commands only make sense when running within the gdb/
- sub-directory.
-
- However, my debugging experience doesn't seem to be degraded at all, I
- can still see the GDB source code just fine; which is because the
- directory list still contains $cdir.
-
- The build/gdb/gdb-gdb.gdb script is created from the
- src/gdb/gdb-gdb.gdb.in template, which includes the automake @srcdir@
- markers.
-
- The 'dir' commands have mostly been around since the sourceware
- repository was first created, though this commit 67f0714670383a did
- reorder some of the 'dir' commands, which would seem to indicate these
- commands were important to some people, at some time.
-
- One possible fix would be to replace @srcdir@ with @abs_srcdir@, this
- would ensure that the entries added were all valid, no matter the
- user's current directory when debugging GDB.
-
- However... I'd like to propose that we instead remove all the extra
- directories completely. My hope is that, with more recent tools, the
- debug information should allow us to correctly find all of the source
- files without having to add any extra 'dir' entries. Obviously,
- commit 67f0714670383a does make me a little nervous, but the
- gdb-gdb.gdb script isn't something a non-maintainer will be using, so
- I think we can afford to be a little more aggressive here. If it
- turns out the 'dir' entries are needed then we can add them back, but
- actually document why they are needed. Plus, when we add them back we
- will use @abs_srcdir@ instead of @srcdir@.

-
- ISTM me there's no reason for the i386 unwinders to be there for amd64.
-
- Furthermore, there's a generic need to play around with enabling and disabling
- unwinders, see PR8434. Currently, that's only available for both the dwarf2
- unwinders at once using "maint set dwarf unwinders on/off".
-
- If I manually disable the "amd64 epilogue" unwinder, the "i386 epilogue"
- unwinder becomes active and gives the wrong answer, while I'm actually
- interested in the result of the dwarf2 unwinder. Of course I can also
- manually disable the "i386 epilogue", but I take the fact that I have to do
- that as evidence that on amd64, the "i386 epilogue" is not only unnecessary,
- but in the way.
-
- Fix this by only adding the i386 unwinders if
- "info.bfd_arch_info->bits_per_word == 32".
-
- Note that the x32 abi (x86_64/-mx32):
- - has the same unwinder list as amd64 (x86_64/-m64) before this commit,
- - has info.bfd_arch_info->bits_per_word == 64, the same as amd64, and
- consequently,
- - has the same unwinder list as amd64 after this commit.

- objdump -D of bss sections and -s with -j
- There is some inconsistency between the behaviour of objdump -D and

- objdump -s ignores bss sections, while objdump -D dissassembles the

- This change does find some tests that used objdump -D with expected

- gdb/source: Fix open_source_file error handling

-
- open_source_file may also call debuginfod_find_source. It is possible
- for debuginfod_find_source to set errno to a value unrelated to the
- reason for a failed download.
-
- This can result in bogus error messages being reported as the reason for

- "No such file or directory":
-
- Temporary breakpoint 1, 0x00005555556f4de0 in main ()

- 1 /usr/src/debug/glibc-2.36-8.fc37.x86_64/elf/<built-in>: Directory not empty.
-
- Fix this by having open_source_file return a negative errno if it fails

- GDB: Introduce limited array lengths while printing values
- This commit introduces the idea of loading only part of an array in
- order to print it, what I call "limited length" arrays.
-
- The motivation behind this work is to make it possible to print slices
- of very large arrays, where very large means bigger than
- `max-value-size'.
-
- Consider this GDB session with the current GDB:
-
- (gdb) set max-value-size 100
- (gdb) p large_1d_array
- value requires 400 bytes, which is more than max-value-size
- (gdb) p -elements 10 -- large_1d_array
- value requires 400 bytes, which is more than max-value-size
-
- notice that the request to print 10 elements still fails, even though 10
- elements should be less than the max-value-size. With a patched version
- of GDB:
-
- (gdb) p -elements 10 -- large_1d_array
- $1 = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9...}
-
- So now the print has succeeded. It also has loaded `max-value-size'
- worth of data into value history, so the recorded value can be accessed
- consistently:
-
- (gdb) p -elements 10 -- $1
- $2 = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9...}
- (gdb) p $1
- $3 = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19,
- 20, 21, 22, 23, 24, <unavailable> <repeats 75 times>}
- (gdb)
-
- Accesses with other languages work similarly, although for Ada only
- C-style [] array element/dimension accesses use history. For both Ada
- and Fortran () array element/dimension accesses go straight to the
- inferior, bypassing the value history just as with C pointers.

- GDB: Only make data actually retrieved into value history available
- While it makes sense to allow accessing out-of-bounds elements in the
- debuggee and see whatever there might happen to be there in memory (we
- are a debugger and not a programming rules enforcement facility and we
- want to make people's life easier in chasing bugs), e.g.:
-
- (gdb) print one_hundred[-1]
- $1 = 0
- (gdb) print one_hundred[100]
- $2 = 0
- (gdb)
-
- we shouldn't really pretend that we have any meaningful data around
- values recorded in history (what these commands really retrieve are
- current debuggee memory contents outside the original data accessed,
- really confusing in my opinion). Mark values recorded in history as
- such then and verify accesses to be in-range for them:
-
- (gdb) print one_hundred[-1]
- $1 = <unavailable>
- (gdb) print one_hundred[100]
- $2 = <unavailable>
-
- Add a suitable test case, which also covers integer overflows in data
- location calculation.

- GDB: Fix the mess with value byte/bit range types
- Consistently use the LONGEST and ULONGEST types for value byte/bit
- offsets and lengths respectively, avoiding silent truncation for ranges
- exceeding the 32-bit span, which may cause incorrect matching. Also
- report a conversion overflow on byte ranges that cannot be expressed in
- terms of bits with these data types, e.g.:
-
- (gdb) print one_hundred[1LL << 58]
- Integer overflow in data location calculation
- (gdb) print one_hundred[(-1LL << 58) - 1]
- Integer overflow in data location calculation
- (gdb)
-
- Previously such accesses would be let through with unpredictable results
- produced.

-
- GDB: Ignore `max-value-size' setting with value history accesses
- We have an inconsistency in value history accesses where array element
- accesses cause an error for entries exceeding the currently selected
- `max-value-size' setting even where such accesses successfully complete
- for elements located in the inferior, e.g.:
-
- (gdb) p/d one
- $1 = 0
- (gdb) p/d one_hundred
- $2 = {0 <repeats 100 times>}
- (gdb) p/d one_hundred[99]
- $3 = 0
- (gdb) set max-value-size 25
- (gdb) p/d one_hundred
- value requires 100 bytes, which is more than max-value-size
- (gdb) p/d one_hundred[99]
- $7 = 0
- (gdb) p/d $2
- value requires 100 bytes, which is more than max-value-size
- (gdb) p/d $2[99]
- value requires 100 bytes, which is more than max-value-size
- (gdb)
-
- According to our documentation the `max-value-size' setting is a safety
- guard against allocating an overly large amount of memory. Moreover a
- statement in documentation says, concerning this setting, that: "Setting
- this variable does not affect values that have already been allocated
- within GDB, only future allocations." While in the implementer-speak
- the sentence may be unambiguous I think the outside user may well infer
- that the setting does not apply to values previously printed.
-
- Therefore rather than just fixing this inconsistency it seems reasonable
- to lift the setting for value history accesses, under an implication
- that by having been retrieved from the debuggee they have already passed
- the safety check. Do it then, by suppressing the value size check in
- `value_copy' -- under an observation that if the original value has been
- already loaded (i.e. it's not lazy), then it must have previously passed
- said check -- making the last two commands succeed:
-
- (gdb) p/d $2
- $8 = {0 <repeats 100 times>}
- (gdb) p/d $2 [99]
- $9 = 0
- (gdb)
-
- Expand the testsuite accordingly, covering both value history handling
- and the use of `value_copy' by `make_cv_value', used by Python code.

- The "Continuing with signal SIGINT" portion is printed by the top GDB,

-
- Fix this by splitting the gdb_test_multiple in two. The first one

- RISC-V: Reduce effective linker relaxation passses
- Commit 43025f01a0c9 ("RISC-V: Improve link time complexity.") reduced the
- time complexity of the linker relaxation but some code portions did not
- reflect this change.
-
- This commit fixes a comment describing each relaxation pass and reduces
- actual number of passes for the RISC-V linker relaxation from 3 to 2.
- Though it does not change the functionality, it marginally improves the
- performance while linking large programs (with many relocations).
-
- bfd/ChangeLog:
-
- * elfnn-riscv.c (_bfd_riscv_relax_section): Fix a comment to
- reflect current roles of each relaxation pass.
-
- ld/ChangeLog:
-
- * emultempl/riscvelf.em: Reduce the number of linker relaxation
- passes from 3 to 2.

- Fix mmo memory leaks
- The main one here is the section buffer, which can be quite large.
- By using alloc rather than malloc we can leave tidying memory to the
- generic bfd code when the bfd is closed. bfd_check_format also
- releases memory when object_p fails, so while it wouldn't be wrong
- to bfd_release at bad_format_free in mmo_object_p, it's a little extra
- code and work for no gain.
-
- * mmo.c (mmo_object_p): bfd_alloc rather than bfd_malloc
- lop_stab_symbol. Don't free/release on error.
- (mmo_get_spec_section): bfd_zalloc rather than bfd_zmalloc
- section buffer.
- (mmo_scan): Free fname on another error path.

- x86: drop use of VEX3SOURCES
- The attribute really specifies that the sum of register and memory
- operands is 4. Express it like that in most places, while using the 2nd
- (apart from XOP) CPU feature flags (FMA4) in reversed operand matching
- logic.
-
- With the use in build_modrm_byte() gone, part of an assertion there
- also becomes meaningless - simplify that at the same time.
-
- With all uses of the opcode modifier field gone, also drop that.

-
- x86: drop use of XOP2SOURCES
- The few XOP insns which used it wrongly didn't have VexVVVV specified.
- With that added, the only further missing piece to use more generic code
- elsewhere is SwapSources - see e.g. the BMI2 insns for similar operand
- patterns.
-
- With the only users gone, drop the #define as well as the special case
- code.

-
- x86: limit use of XOP2SOURCES
- The VPROT* forms with an immediate operand are entirely standard in the
- way their ModR/M bytes are built. There's no reason to invoke special
- case code. With that the handling of an immediate there can also be
- dropped; it was partially bogus anyway, as in its "no memory operands"
- portion it ignores the possibility of an immediate operand (which was
- okay only because that case was already handled by more generic code).

- helps readability at the use sites, by shortening the references quite a
- bit.

- Add full display feature to dwarf-mode.el
- I've found that I often use dwarf-mode with relatively small test
- files. In this situation, it's handy to be able to expand all the
- DWARF, rather than moving to each "..." separately and using C-u C-m.
-
- This patch implements this feature. It also makes a couple of other
- minor changes:
-
- * I removed a stale FIXME from dwarf-mode. In practice I find I often
- use "g" to restore the buffer to a pristine state; checking the file
- mtime would work against this.
-
- * I tightened the regexp in dwarf-insert-substructure. This prevents
- the C-m binding from trying to re-read a DIE which has already been
- expanded.
-
- * Finally, I've bumped the dwarf-mode version number so that this
- version can easily be installed using package.el.

- (dwarf-insert-substructure): Tighten regexp.

- (dwarf-mode): Remove old FIXME.

- Increase size of main_type::nfields
- main_type::nfields is a 'short', and has been for many years. PR
- c++/29985 points out that 'short' is too narrow for an enum that
- contains more than 2^15 constants.
-
- This patch bumps the size of 'nfields'. To verify that the field
- isn't directly used, it is also renamed. Note that this does not
- affect the size of main_type on x86-64 Fedora 36. And, if it does
- have a negative effect somewhere, it's worth considering that types
- could be shrunk more drastically by using subclasses for the different
- codes.
-
- This is v2 of this patch, which has these changes:
-
- * I changed nfields to 'unsigned', per Simon's request. I looked at
- changing all the uses, but this quickly fans out into a very large
- patch. (One additional tweak was needed, though.)
-
- * I wrote a test case. I discovered that GCC cannot compile a large
- enough C test case, so I resorted to using the DWARF assembler.
- This test doesn't reproduce the crash, but it does fail without the
- patch.

- Let user C-c when waiting for DWARF index finalization
- In PR gdb/29854, Simon pointed out that it would be good to be able to
- use C-c when the DWARF cooked index is waiting for finalization. The
- idea here is to be able to interrupt a command like "break" -- not to
- stop the finalization process itself, which runs in a worker thread.
-
- This patch implements this idea, by changing the index wait functions
- to, by default, allow a quit. Polling is done, because there doesn't
- seem to be a better way to interrupt a wait on a std::future.
-
- For v2, I realized that the thread compatibility code in thread-pool.h

- Clear cached file size when bfd changed to BFD_IN_MEMORY
- If file size is calculated by bfd_get_file_size, as it is by
- _bfd_alloc_and_read calls in coff_object_p, then it is cached and when
- pe_ILF_build_a_bfd converts an archive entry over to BFD_IN_MEMORY,
- the file size is no longer valid. Found when attempting objdump -t on
- a very small (27 bytes) ILF file and hitting the pr24707 fix (commit
- 781152ec18f5). So, clear file size when setting BFD_IN_MEMORY on bfds
- that may have been read. (It's not necessary in writable bfds,
- because caching is ignored by bfd_get_size when bfd_write_p.)
-
- I also think the PR 24707 fix is no longer neeeded. All of the
- testcases in that PR and in PR24712 are caught earlier by file size
- checks when reading the symbols from file. So I'm reverting that fix,
- which just compared the size of an array of symbol pointers against
- file size. That's only valid if on-disk symbols are larger than a
- host pointer, so the test is better done in format-specific code.

- gdb: give sentinel for user frames distinct IDs, register sentinel frames to the frame cache
- The test gdb.base/frame-view.exp fails like this on AArch64:
-
- frame^M
- #0 baz (z1=hahaha, /home/simark/src/binutils-gdb/gdb/value.c:4056: internal-error: value_fetch_lazy_register: Assertion `next_frame != NULL' failed.^M
- A problem internal to GDB has been detected,^M
- further debugging may prove unreliable.^M
- FAIL: gdb.base/frame-view.exp: with_pretty_printer=true: frame (GDB internal error)
-
- The sequence of events leading to this is the following:
-
- - When we create the user frame (the "select-frame view" command), we
- create a sentinel frame just for our user-created frame, in
- create_new_frame. This sentinel frame has the same id as the regular
- sentinel frame.
-
- - When printing the frame, after doing the "select-frame view" command,
- the argument's pretty printer is invoked, which does an inferior
- function call (this is the point of the test). This clears the frame
- cache, including the "real" sentinel frame, which sets the
- sentinel_frame global to nullptr.
-
- - Later in the frame-printing process (when printing the second
- argument), the auto-reinflation mechanism re-creates the user frame
- by calling create_new_frame again, creating its own special sentinel
- frame again. However, note that the "real" sentinel frame, the
- sentinel_frame global, is still nullptr. If the selected frame had
- been a regular frame, we would have called get_current_frame at some
- point during the reinflation, which would have re-created the "real"
- sentinel frame. But it's not the case when reinflating a user frame.
-
- - Deep down the stack, something wants to fill in the unwind stop
- reason for frame 0, which requires trying to unwind frame 1. This
- leads us to trying to unwind the PC of frame 1:

- - AArch64 defines a special "prev register" function,
- aarch64_dwarf2_prev_register, to handle unwinding the PC. This
- function does
-
- frame_unwind_register_unsigned (this_frame, AARCH64_LR_REGNUM);
-
- - frame_unwind_register_unsigned ultimately creates a lazy register
- value, saving the frame id of this_frame->next. this_frame is the
- user-created frame, to this_frame->next is the special sentinel frame
- we created for it. So the saved ID is the sentinel frame ID.
-
- - When time comes to un-lazify the value, value_fetch_lazy_register
- calls frame_find_by_id, to find the frame with the ID we saved.
-
- - frame_find_by_id sees it's the sentinel frame ID, so returns the
- sentinel_frame global, which is, if you remember, nullptr.
-
- - We hit the `gdb_assert (next_frame != NULL)` assertion in
- value_fetch_lazy_register.
-
- The issues I see here are:
-
- - The ID of the sentinel frame created for the user-created frame is
- not distinguishable from the ID of the regular sentinel frame. So
- there's no way frame_find_by_id could find the right frame, in
- value_fetch_lazy_register.
- - Even if they had distinguishable IDs, sentinel frames created for
- user frames are not registered anywhere, so there's no easy way
- frame_find_by_id could find it.
-
- This patch addresses these two issues:
-
- - Give sentinel frames created for user frames their own distinct IDs
- - Register sentinel frames in the frame cache, so they can be found
- with frame_find_by_id.
-
- I initially had this split in two patches, but I then found that it was
- easier to explain as a single patch.
-
- Rergarding the first part of the change: with this patch, the sentinel
- frames created for user frames (in create_new_frame) still have
- stack_status == FID_STACK_SENTINEL, but their code_addr and stack_addr
- fields are now filled with the addresses used to create the user frame.
- This ensures this sentinel frame ID is different from the "target"
- sentinel frame ID, as well as any other "user" sentinel frame ID. If
- the user tries to create the same frame, with the same addresses,
- multiple times, create_sentinel_frame just reuses the existing frame.
- So we won't end up with multiple user sentinels with the same ID.
-
- Regular "target" sentinel frames remain with code_addr and stack_addr
- unset.
-
- The concrete changes for that part are:
-
- - Remove the sentinel_frame_id constant, since there isn't one
- "sentinel frame ID" now. Add the frame_id_build_sentinel function
- for building sentinel frame IDs and a is_sentinel_frame_id function
- to check if a frame id represents a sentinel frame.
- - Replace the sentinel_frame_id check in frame_find_by_id with a
- comparison to `frame_id_build_sentinel (0, 0)`. The sentinel_frame
- global is meant to contain a reference to the "target" sentinel, so
- the one with addresses (0, 0).
- - Add stack and code address parameters to create_sentinel_frame, to be
- able to create the various types of sentinel frames.
- - Adjust get_current_frame to create the regular "target" sentinel.
- - Adjust create_new_frame to create a sentinel with the ID specific to
- the created user frame.
- - Adjust sentinel_frame_prev_register to get the sentinel frame ID from
- the frame_info object, since there isn't a single "sentinel frame ID"
- now.
- - Change get_next_frame_sentinel_okay to check for a
- sentinel-frame-id-like frame ID, rather than for sentinel_frame
- specifically, since this function could be called with another
- sentinel frame (and we would want the assert to catch it).
-
- The rest of the change is about registering the sentinel frame in the
- frame cache:
-
- - Change frame_stash_add's assertion to allow sentinel frame levels
- (-1).
- - Make create_sentinel_frame add the frame to the frame cache.
- - Change the "sentinel_frame != NULL" check in reinit_frame_cache for a
- check that the frame stash is not empty. The idea is that if we only
- have some user-created frames in the cache when reinit_frame_cache is
- called, we probably want to emit the frames invalid annotation. The
- goal of that check is to avoid unnecessary repeated annotations, I
- suppose, so the "frame cache not empty" check should achieve that.
-
- After this change, I think we could theoritically get rid of the
- sentienl_frame global. That sentinel frame could always be found by
- looking up `frame_id_build_sentinel (0, 0)` in the frame cache.
- However, I left the global there to avoid slowing the typical case down
- for nothing. I however, noted in its comment that it is an
- optimization.
-
- With this fix applied, the gdb.base/frame-view.exp now passes for me on
- AArch64. value_of_register_lazy now saves the special sentinel frame ID
- in the value, and value_fetch_lazy_register is able to find that
- sentinel frame after the frame cache reinit and after the user-created
- frame was reinflated.

- gdb: call frame unwinders' dealloc_cache methods through destroying the frame cache
- Currently, some frame resources are deallocated by iterating on the
- frame chain (starting from the sentinel), calling dealloc_cache. The
- problem is that user-created frames are not part of that chain, so we
- never call dealloc_cache for them.
-
- I propose to make it so the dealloc_cache callbacks are called when the
- frames are removed from the frame_stash hash table, by registering a
- deletion function to the hash table. This happens when
- frame_stash_invalidate is called by reinit_frame_cache. This way, all
- frames registered in the cache will get their unwinder's dealloc_cache
- callbacks called.
-
- Note that at the moment, the sentinel frames are not registered in the
- cache, so we won't call dealloc_cache for them. However, it's just a
- theoritical problem, because the sentinel frame unwinder does not
- provide this callback. Also, a subsequent patch will change things so
- that sentinel frames are registered to the cache.
-
- I moved the obstack_free / obstack_init pair below the
- frame_stash_invalidate call in reinit_frame_cache, because I assumed
- that some dealloc_cache would need to access some data on that obstack,
- so it would be better to free it after clearing the hash table.

- Remove block.h includes from some tdep files
- A few tdep files include block.h but do not need to. This patch
- removes the inclusions. I checked that this worked correctly by
- examining the resulting .Po file to make sure that block.h was not
- being included by some other route.
-
- Don't include block.h from expop.h
- expop.h needs block.h for a single inline function. However, I don't
- think most of the check_objfile functions need to be defined in the
- header (just the templates). This patch moves the one offending
- function and removes the include.

- Simplify interp::exec / interp_exec - let exceptions propagate
- This patch implements a simplication that I suggested here:
-
- https://sourceware.org/pipermail/gdb-patches/2022-March/186320.html
-
- Currently, the interp::exec virtual method interface is such that
- subclass implementations must catch exceptions and then return them
- via normal function return.
-
- However, higher up the in chain, for the CLI we get to
- interpreter_exec_cmd, which does:
-
- for (i = 1; i < nrules; i++)
- {
- struct gdb_exception e = interp_exec (interp_to_use, prules[i]);
-
- if (e.reason < 0)
- {
- interp_set (old_interp, 0);
- error (_("error in command: \"%s\"."), prules[i]);
- }
- }
-
- and for MI we get to mi_cmd_interpreter_exec, which has:
-
- void
- mi_cmd_interpreter_exec (const char *command, char **argv, int argc)
- {
- ...
- for (i = 1; i < argc; i++)
- {
- struct gdb_exception e = interp_exec (interp_to_use, argv[i]);
-
- if (e.reason < 0)
- error ("%s", e.what ());
- }
- }
-
- Note that if those errors are reached, we lose the original
- exception's error code. I can't see why we'd want that.
-
- And, I can't see why we need to have interp_exec catch the exception
- and return it via the normal return path. That's normally needed when
- we need to handle propagating exceptions across C code, like across
- readline or ncurses, but that's not the case here.
-
- It seems to me that we can simplify things by removing some
- try/catch-ing and just letting exceptions propagate normally.
-
- Note, the "error in command" error shown above, which only exists in
- the CLI interpreter-exec command, is only ever printed AFAICS if you
- run "interpreter-exec console" when the top level interpreter is
- already the console/tui. Like:
-
- (gdb) interpreter-exec console "foobar"
- Undefined command: "foobar". Try "help".
- error in command: "foobar".
-
- You won't see it with MI's "-interpreter-exec console" from a top
- level MI interpreter:
-
- (gdb)
- -interpreter-exec console "foobar"
- &"Undefined command: \"foobar\". Try \"help\".\n"
- ^error,msg="Undefined command: \"foobar\". Try \"help\"."
- (gdb)
-
- nor with MI's "-interpreter-exec mi" from a top level MI interpreter:
-
- (gdb)
- -interpreter-exec mi "-foobar"
- ^error,msg="Undefined MI command: foobar",code="undefined-command"
- ^done
- (gdb)
-
- in both these cases because MI's -interpreter-exec just does:
-
- error ("%s", e.what ());
-
- You won't see it either when running an MI command with the CLI's
- "interpreter-exec mi":
-
- (gdb) interpreter-exec mi "-foobar"
- ^error,msg="Undefined MI command: foobar",code="undefined-command"
- (gdb)
-
- This last case is because MI's interp::exec implementation never
- returns an error:
-
- gdb_exception
- mi_interp::exec (const char *command)
- {
- mi_execute_command_wrapper (command);
- return gdb_exception ();
- }
-
- Thus I think that "error in command" error is pretty pointless, and
- since it simplifies things to not have it, the patch just removes it.
-
- The patch also ends up addressing an old FIXME.

- Avoid FAILs in gdb.compile
- Many gdb.compile C++ tests fail for me on Fedora 36. I think these
- are largely bugs in the plugin, though I didn't investigate too
- deeply. Once one failure is seen, this often cascades and sometimes
- there are many timeouts.
-
- For example, this can happen:
-
- (gdb) compile code var = a->get_var ()
- warning: Could not find symbol "_ZZ9_gdb_exprP10__gdb_regsE1a" for compiled module "/tmp/gdbobj-0xdI6U/out2.o".
- 1 symbols were missing, cannot continue.
-
- I think this is probably a plugin bug because, IIRC, in theory these
- symbols should be exempt from a lookup via gdb.
-
- This patch arranges to catch any catastrophic failure and then simply
- exit the entire .exp file.

-
- Merge fixup_section and fixup_symbol_section
- fixup_symbol_section delegates all its work to fixup_section, so merge
- the two.
-
- Because there is only a single caller to fixup_symbol_section, we can
- also remove some of the introductory logic. For example, this will
- never be called with a NULL objfile any more.
-
- The LOC_BLOCK case can be removed, because such symbols are handled by
- the buildsym code now.
-
- Finally, a symbol can only appear in a SEC_ALLOC section, so the loop
- is modified to skip sections that do not have this flag set.
-
-2023-02-08 Tom Tromey <tromey@adacore.com>
-
- Remove most calls to fixup_symbol_section
- Nearly every call to fixup_symbol_section in gdb is incorrect, and if
- any such call has an effect, it's purely by happenstance.
-
- fixup_section has a long comment explaining that the call should only
- be made before runtime section offsets are applied. And, the loop in
- this code (the fallback loop -- the minsym lookup code is "ok") is
- careful to remove these offsets before comparing addresses.
-
- However, aside from a single call in dwarf2/read.c, every call in gdb
- is actually done after section offsets have been applied. So, these
- calls are incorrect.
-
- Now, these calls could be made when the symbol is created. I
- considered this approach, but I reasoned that the code has been this
- way for many years, seemingly without ill effect. So, instead I chose
- to simply remove the offending calls.
-
-2023-02-08 Tom Tromey <tromey@adacore.com>
-
- Set section index when setting a symbol's block
- When a symbol's block is set, the block has the runtime section offset
- applied. So, it seems to me that the symbol implicitly is in the same
- section as the block. Therefore, this patch sets the symbol's section
- index at this same spot.
-
- Remove compunit_symtab::m_block_line_section
- The previous patch hard-coded SECT_OFF_TEXT into the buildsym code.
- After this, it's clear that there is only one caller of
- compunit_symtab::set_block_line_section, and it always passes
- SECT_OFF_TEXT. So, remove compunit_symtab::m_block_line_section and
- use SECT_OFF_TEXT instead.
-
- Do not pass section index to end_compunit_symtab
- Right now, the section index passed to end_compunit_symtab is always
- SECT_OFF_TEXT. Remove this parameter and simply always use
- SECT_OFF_TEXT.
-
-2023-02-08 Tom Tromey <tromey@adacore.com>
-
- Set section indices when symbols are made
- Most places in gdb that create a new symbol will apply a section
- offset to the address. It seems to me that the choice of offset here
- is also an implicit choice of the section. This is particularly true
- if you examine fixup_section, which notes that it must be called
- before such offsets are applied -- meaning that if any such call has
- an effect, it's purely by accident.
-
- This patch cleans up this area by tracking the section index and
- applying it to a symbol when the address is set. This is done for
- nearly every case -- the remaining cases will be handled in later
- patches.

-
- Use default section indexes in fixup_symbol_section
- If fixup_section does not find a matching section, it arbitrarily
- chooses the first one. However, it seems better to make this default
- depend on the type of the symbol -- i.e., default data symbols to
- .data and text symbols to .text.
-
- I've also made fixup_section static, as it only has one caller.

- gdb: fix display of thread condition for multi-location breakpoints
- This commit addresses the issue in PR gdb/30087.
-
- If a breakpoint with multiple locations has a thread condition, then
- the 'info breakpoints' output is a little messed up, here's an example
- of the current output:
-
- (gdb) break foo thread 1
- Breakpoint 2 at 0x401114: foo. (3 locations)
- (gdb) break bar thread 1
- Breakpoint 3 at 0x40110a: file /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c, line 32.
- (gdb) info breakpoints
- Num Type Disp Enb Address What
- 2 breakpoint keep y <MULTIPLE> thread 1
- stop only in thread 1
- 2.1 y 0x0000000000401114 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25
- 2.2 y 0x0000000000401146 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25
- 2.3 y 0x0000000000401168 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25
- 3 breakpoint keep y 0x000000000040110a in bar at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:32 thread 1
- stop only in thread 1
-
- Notice that, at the end of the location for breakpoint 3, the 'thread
- 1' condition is printed, but this is then repeated on the next line
- with 'stop only in thread 1'.
-
- In contrast, for breakpoint 2, the 'thread 1' appears randomly, in the
- "What" column, though slightly offset, non of the separate locations
- have the 'thread 1' information. Additionally for breakpoint 2 we
- also get a 'stop only in thread 1' line.
-
- There's two things going on here. First the randomly placed 'thread
- 1' for breakpoint 2 is due to a bug in print_one_breakpoint_location,
- where we check the variable part_of_multiple instead of
- header_of_multiple.
-
- If I fix this oversight, then the output is now:
-
- (gdb) break foo thread 1
- Breakpoint 2 at 0x401114: foo. (3 locations)
- (gdb) break bar thread 1
- Breakpoint 3 at 0x40110a: file /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c, line 32.
- (gdb) info breakpoints
- Num Type Disp Enb Address What
- 2 breakpoint keep y <MULTIPLE>
- stop only in thread 1
- 2.1 y 0x0000000000401114 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25 thread 1

- 2.3 y 0x0000000000401168 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25 thread 1
- 3 breakpoint keep y 0x000000000040110a in bar at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:32 thread 1
- stop only in thread 1
-
- The 'thread 1' condition is now displayed at the end of each location,
- which makes the output the same for single location breakpoints and
- multi-location breakpoints.
-
- However, there's still some duplication here. Both breakpoints 2 and
- 3 include a 'stop only in thread 1' line, and it feels like the
- additional 'thread 1' is redundant. In fact, there's a comment to
- this very effect in the code:
-
- /* FIXME: This seems to be redundant and lost here; see the
- "stop only in" line a little further down. */
-
- So, lets fix this FIXME. The new plan is to remove all the trailing
- 'thread 1' markers from the CLI output, we now get this:
-
- (gdb) break foo thread 1
- Breakpoint 2 at 0x401114: foo. (3 locations)
- (gdb) break bar thread 1
- Breakpoint 3 at 0x40110a: file /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c, line 32.
- (gdb) info breakpoints
- Num Type Disp Enb Address What
- 2 breakpoint keep y <MULTIPLE>
- stop only in thread 1
- 2.1 y 0x0000000000401114 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25
- 2.2 y 0x0000000000401146 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25
- 2.3 y 0x0000000000401168 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25
- 3 breakpoint keep y 0x000000000040110a in bar at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:32
- stop only in thread 1
-
- All of the above points are also true for the Ada 'task' breakpoint
- condition, and the changes I've made also update how the task
- information is printed, though in the case of the Ada task there was
- no 'stop only in task XXX' line printed, so I've added one of those.
-
- Obviously it can't be quite that easy. For MI backwards compatibility
- I've retained the existing code (but now only for MI like outputs),
- which ensures we should generate backwards compatible output.
-
- I've extended an Ada test to cover the new task related output, and
- updated all the tests I could find that checked for the old output.

- 'thread' is given more than once.
-
- In this commit I propose making this behaviour consistent, if the
- 'thread' or 'task' keywords are used more than once when creating
- either a breakpoint or watchpoint, then GDB will give an error.
-
- I haven't updated the manual, we don't explicitly say that these
- keywords can be repeated, and (to me), given the keyword takes a
- single id, I don't think it makes much sense to repeat the keyword.
- As such, I see this more as adding a missing error to GDB, rather than
- making some big change. However, I have added an entry to the NEWS
- file as I guess it is possible that some people might hit this new
- error with an existing (I claim, badly written) GDB script.
-
- I've added some new tests to check for the new error.
-
- Just one test needed updating, gdb.linespec/keywords.exp, this test
- did use the 'thread' keyword twice, and expected the breakpoint to be
- created. Looking at what this test was for though, it was checking
- the use of '-force-condition', and I don't think that being able to
- repeat 'thread' was actually a critical part of this test.
-
- As such, I've updated this test to expect the error when 'thread' is
- repeated.

- Resetting section vma after _bfd_dwarf2_find_nearest_line
- There are failure paths in _bfd_dwarf2_slurp_debug_info that can
- result in altered section vmas. Also, when setting ET_REL section
- vmas it's not too difficult to handle cases where the original vma was
- non-zero, so do that too.
-
- This patch was really in response to an addr2line buffer overflow
- processing a fuzzed mips relocatable object file. The file had a
- number of .debug_info sections with relocations that included lo16 and
- hi16 relocs, and in that order. At least one section VMA was
- non-zero. This resulted in processing of DWARF info twice, once via
- the call to _bfd_dwarf2_find_nearest_line in
- _bfd_mips_elf_find_nearest_line, and because that failed leaving VMAs
- altered, the second via the call in _bfd_elf_find_nearest_line. The
- first call left entries on mips_hi16_list pointing at buffers
- allocated during the first call, the second call processed the
- mips_hi16_list after the buffers had been freed. (At least when
- running with asan and under valgrind. Under gdb with a non-asan
- addr2line the second call allocated exactly the same buffer and the
- bug didn't show.) Now I don't really care too much what happens with
- fuzzed files, but the logic in _bfd_dwarf2_find_nearest_line is meant
- to result in only one read of .debug_info, not multiple reads of the
- same info when there are errors. This patch fixes that problem.
-
- * dwarf2.c (struct adjusted_section): Add orig_vma.
- (unset_sections): Reset vma to it.
- (place_sections): Handle non-zero vma too. Save orig_vma.
- (_bfd_dwarf2_slurp_debug_info): Tidy. Correct outdated comment.
- On error returns after calling place_sections, call
- unset_sections.
- (_bfd_dwarf2_find_nearest_line_with_alt): Simplify call to
- unset_sections.

- gdb/testsuite: don't try to set non-stop mode on a running target
- The test gdb.threads/thread-specific-bp.exp tries to set non-stop mode
- on a running target, something which the manual makes clear is not
- allowed.
-
- This commit restructures the test a little, we now set the non-stop
- mode as part of the GDBFLAGS, so the mode will be set before GDB
- connects to the target. As a consequence I'm able to move the
- with_test_prefix out of the check_thread_specific_breakpoint proc.
- The check_thread_specific_breakpoint proc is now called within a loop.
-
- After this commit the gdb.threads/thread-specific-bp.exp test still

- ld: pru: Add optional section alignments
- The Texas Instruments SoCs with AARCH64 host processors have stricter
- alignment requirements than ones with ARM32 host processors. It's not
- only the requirement for resource_table to be aligned to 8. But also
- any loadable segment size must be a multiple of 4 [1].
-
- The current PRU default linker script may output a segment size not
- aligned to 4, which would cause firmware load failure on AARCH64 hosts.
-
- Fix this by using COMMONPAGESIZE and MAXPAGESIZE to signify respectively
- the section memory size requirement and the resource table section's
- start address alignment. This would avoid penalizing the ARM32 hosts,
- for which the default values (1 and 1) are sufficient.
-
- For AARCH64 hosts, the alignments would be overwritten from GCC spec
- files using the linker command line, e.g.:
- -z common-page-size=4 -z max-page-size=8

- ld: pru: Merge the bss input sections into data
- The popular method to load PRU firmware is through the remoteproc Linux
- kernel driver. In order to save a few bytes from the firmware, the PRU
- CRT0 is spared from calling memset for the bss segment [1]. Instead the
- host loader is supposed to zero out the bss segment. This is important
- for PRU, which typically has only 8KB for instruction memory.
-
- The legacy non-mainline PRU host driver relied on the default
- behaviour of the kernel core remoteproc [2]. That default is to zero
- out the loadable memory regions not backed by file storage (i.e. the
- bss sections). This worked for the libgloss' CRT0.
-
- But the PRU loader merged in mainline Linux explicitly changes the
- default behaviour [3]. It no longer is zeroing out memory regions.
- Hence the bss sections are not initialized - neither by CRT0, nor by the
- host loader.
-
- This patch fixes the issue by aligning the GNU LD default linker script
- with the mainline Linux kernel expectation. Since the mainline kernel
- driver is submitted by the PRU manufacturer itself (Text Instruments),
- we can consider that as defining the ABI.
-
- This change has been tested on Beaglebone AI-64 [4]. Static counter
- variables in the firmware are now always starting from zero, as
- expected. There was only one new toolchain test failure in orphan3.d,
- due to reordering of the output sections. I believe this is a harmless
- issue. I could not rewrite the PASS criteria to ignore the output
- section ordering, so I have disabled that test case for PRU.

- gdb: initial support for ROCm platform (AMDGPU) debugging
- This patch adds the foundation for GDB to be able to debug programs
- offloaded to AMD GPUs using the AMD ROCm platform [1]. The latest
- public release of the ROCm release at the time of writing is 5.4, so
- this is what this patch targets.
-
- The ROCm platform allows host programs to schedule bits of code for
- execution on GPUs or similar accelerators. The programs running on GPUs
- are typically referred to as `kernels` (not related to operating system
- kernels).
-
- Programs offloaded with the AMD ROCm platform can be written in the HIP
- language [2], OpenCL and OpenMP, but we're going to focus on HIP here.
- The HIP language consists of a C++ Runtime API and kernel language.
- Here's an example of a very simple HIP program:
-
- #include "hip/hip_runtime.h"
- #include <cassert>
-
- __global__ void
- do_an_addition (int a, int b, int *out)
- {
- *out = a + b;
- }
-
- int
- main ()
- {
- int *result_ptr, result;
-
- /* Allocate memory for the device to write the result to. */
- hipError_t error = hipMalloc (&result_ptr, sizeof (int));
- assert (error == hipSuccess);
-
- /* Run `do_an_addition` on one workgroup containing one work item. */
- do_an_addition<<<dim3(1), dim3(1), 0, 0>>> (1, 2, result_ptr);
-
- /* Copy result from device to host. Note that this acts as a synchronization
- point, waiting for the kernel dispatch to complete. */
- error = hipMemcpyDtoH (&result, result_ptr, sizeof (int));
- assert (error == hipSuccess);
-
- printf ("result is %d\n", result);
- assert (result == 3);
-
- return 0;
- }
-
- This program can be compiled with:
-
- $ hipcc simple.cpp -g -O0 -o simple
-
- ... where `hipcc` is the HIP compiler, shipped with ROCm releases. This
- generates an ELF binary for the host architecture, containing another
- ELF binary with the device code. The ELF for the device can be
- inspected with:
-
- $ roc-obj-ls simple
- 1 host-x86_64-unknown-linux file://simple#offset=8192&size=0
- 1 hipv4-amdgcn-amd-amdhsa--gfx906 file://simple#offset=8192&size=34216
- $ roc-obj-extract 'file://simple#offset=8192&size=34216'
- $ file simple-offset8192-size34216.co
- simple-offset8192-size34216.co: ELF 64-bit LSB shared object, *unknown arch 0xe0* version 1, dynamically linked, with debug_info, not stripped
- ^
- amcgcn architecture that my `file` doesn't know about ----´
-
- Running the program gives the very unimpressive result:
-
- $ ./simple
- result is 3
-
- While running, this host program has copied the device program into the
- GPU's memory and spawned an execution thread on it. The goal of this
- GDB port is to let the user debug host threads and these GPU threads
- simultaneously. Here's a sample session using a GDB with this patch

- One thing to notice is the host and GPU threads appearing under
- the same inferior. This is a design goal for us, as programmers tend to
- think of the threads running on the GPU as part of the same program as
- the host threads, so showing them in the same inferior in GDB seems
- natural. Also, the host and GPU threads share a global memory space,
- which fits the inferior model.
-
- Another thing to notice is the error messages when trying to read
- variables or printing a backtrace. This is expected for the moment,
- since the AMD GPU compiler produces some DWARF that uses some
- non-standard extensions:
-
- https://llvm.org/docs/AMDGPUDwarfExtensionsForHeterogeneousDebugging.html
-
- There were already some patches posted by Zoran Zaric earlier to make
- GDB support these extensions:
-
- https://inbox.sourceware.org/gdb-patches/20211105113849.118800-1-zoran.zaric@amd.com/
-
- We think it's better to get the basic support for AMD GPU in first,
- which will then give a better justification for GDB to support these
- extensions.
-
- GPU threads are named `AMDGPU Wave`: a wave is essentially a hardware
- thread using the SIMT (single-instruction, multiple-threads) [3]
- execution model.
-
- GDB uses the amd-dbgapi library [4], included in the ROCm platform, for
- a few things related to AMD GPU threads debugging. Different components
- talk to the library, as show on the following diagram:
-
- +---------------------------+ +-------------+ +------------------+
- | GDB | amd-dbgapi target | <-> | AMD | | Linux kernel |
- | +-------------------+ | Debugger | +--------+ |
- | | amdgcn gdbarch | <-> | API | <=> | AMDGPU | |
- | +-------------------+ | | | driver | |
- | | solib-rocm | <-> | (dbgapi.so) | +--------+---------+
- +---------------------------+ +-------------+
-
- - The amd-dbgapi target is a target_ops implementation used to control
- execution of GPU threads. While the debugging of host threads works
- by using the ptrace / wait Linux kernel interface (as usual), control
- of GPU threads is done through a special interface (dubbed `kfd`)
- exposed by the `amdgpu` Linux kernel module. GDB doesn't interact
- directly with `kfd`, but instead goes through the amd-dbgapi library
- (AMD Debugger API on the diagram).
-
- Since it provides execution control, the amd-dbgapi target should
- normally be a process_stratum_target, not just a target_ops. More
- on that later.
-
- - The amdgcn gdbarch (describing the hardware architecture of the GPU
- execution units) offloads some requests to the amd-dbgapi library,
- so that knowledge about the various architectures doesn't need to be
- duplicated and baked in GDB. This is for example for things like
- the list of registers.
-
- - The solib-rocm component is an solib provider that fetches the list of
- code objects loaded on the device from the amd-dbgapi library, and
- makes GDB read their symbols. This is very similar to other solib
- providers that handle shared libraries, except that here the shared
- libraries are the pieces of code loaded on the device.
-
- Given that Linux host threads are managed by the linux-nat target, and
- the GPU threads are managed by the amd-dbgapi target, having all threads
- appear in the same inferior requires the two targets to be in that
- inferior's target stack. However, there can only be one
- process_stratum_target in a given target stack, since there can be only
- one target per slot. To achieve it, we therefore resort the hack^W
- solution of placing the amd-dbgapi target in the arch_stratum slot of
- the target stack, on top of the linux-nat target. Doing so allows the
- amd-dbgapi target to intercept target calls and handle them if they
- concern GPU threads, and offload to beneath otherwise. See
- amd_dbgapi_target::fetch_registers for a simple example:
-
- void
- amd_dbgapi_target::fetch_registers (struct regcache *regcache, int regno)
- {
- if (!ptid_is_gpu (regcache->ptid ()))
- {
- beneath ()->fetch_registers (regcache, regno);
- return;
- }
-
- // handle it
- }
-
- ptids of GPU threads are crafted with the following pattern:
-
- (pid, 1, wave id)
-
- Where pid is the inferior's pid and "wave id" is the wave handle handed
- to us by the amd-dbgapi library (in practice, a monotonically
- incrementing integer). The idea is that on Linux systems, the
- combination (pid != 1, lwp == 1) is not possible. lwp == 1 would always
- belong to the init process, which would also have pid == 1 (and it's
- improbable for the init process to offload work to the GPU and much less
- for the user to debug it). We can therefore differentiate GPU and
- non-GPU ptids this way. See ptid_is_gpu for more details.
-
- Note that we believe that this scheme could break down in the context of
- containers, where the initial process executed in a container has pid 1
- (in its own pid namespace). For instance, if you were to execute a ROCm
- program in a container, then spawn a GDB in that container and attach to
- the process, it will likely not work. This is a known limitation. A
- workaround for this is to have a dummy process (like a shell) fork and
- execute the program of interest.
-
- The amd-dbgapi target watches native inferiors, and "attaches" to them
- using amd_dbgapi_process_attach, which gives it a notifier fd that is
- registered in the event loop (see enable_amd_dbgapi). Note that this
- isn't the same "attach" as in PTRACE_ATTACH, but being ptrace-attached
- is a precondition for amd_dbgapi_process_attach to work. When the
- debugged process enables the ROCm runtime, the amd-dbgapi target gets
- notified through that fd, and pushes itself on the target stack of the
- inferior. The amd-dbgapi target is then able to intercept target_ops
- calls. If the debugged process disables the ROCm runtime, the
- amd-dbgapi target unpushes itself from the target stack.
-
- This way, the amd-dbgapi target's footprint stays minimal when debugging
- a process that doesn't use the AMD ROCm platform, it does not intercept
- target calls.
-
- The amd-dbgapi library is found using pkg-config. Since enabling
- support for the amdgpu architecture (amdgpu-tdep.c) depends on the
- amd-dbgapi library being present, we have the following logic for
- the interaction with --target and --enable-targets:
-
- - if the user explicitly asks for amdgcn support with
- --target=amdgcn-*-* or --enable-targets=amdgcn-*-*, we probe for
- the amd-dbgapi and fail if not found
-
- - if the user uses --enable-targets=all, we probe for amd-dbgapi,
- enable amdgcn support if found, disable amdgcn support if not found
-
- - if the user uses --enable-targets=all and --with-amd-dbgapi=yes,
- we probe for amd-dbgapi, enable amdgcn if found and fail if not found
-
- - if the user uses --enable-targets=all and --with-amd-dbgapi=no,
- we do not probe for amd-dbgapi, disable amdgcn support
-
- - otherwise, amd-dbgapi is not probed for and support for amdgcn is not
- enabled
-
- Finally, a simple test is included. It only tests hitting a breakpoint
- in device code and resuming execution, pretty much like the example
- shown above.

- gdb/solib-svr4: don't disable probes interface if probe not found
- In ROCm-GDB, we install an solib provider for the GPU code objects on
- top of the svr4 provider for the host, in order to add solibs
- representing the GPU code objects to the solib list containing the host
- process' shared libraries. We override the target_so_ops::handle_event
- function pointer with our own, in which we call svr4_so_ops.handle_event
- (which contains svr4_handle_solib_event) manually. When the host
- (un)loads a library, the ROCm part of handle_event is a no-op. When the
- GPU (un)loads a code object, we want the host side (svr4) to be a no-op.
-
- The problem is that when handle_event is called because of a GPU event,
- svr4_handle_solib_event gets called while not stopped at an svr4
- probe. It then assumes this means there's a problem with the probes
- interface and disables it through the following sequence of events:
-
- - solib_event_probe_at return nullptr
- - svr4_handle_solib_event returns early
- - the make_scope_exit callback calls disable_probes_interface
-
- We could fix that by making the ROCm handle_event callback check if an
- svr4 probe is that the stop address, and only call
- svr4_so_ops.handle_event if so. However, it doesn't feel right to
- include some svr4 implementation detail in the ROCm event handler.
-
- Instead, this patch changes svr4_handle_solib_event to not assume it is
- an error if called while not at an svr4 probe location, and therefore
- not disable the probes interface. That just means moving the
- make_scope_exit call below where we lookup the probe by pc.

-
- The problem is that the above commit introduces a direct use of the

-
- To avoid this, in this commit I switch to using runto_main. However,
- calling runto_main will, by default, delete all the currently set
- breakpoints. As the point of the above commit was to check that a
- breakpoint set before stating an inferior would be correctly re-set,
- we need to avoid this breakpoint deleting behaviour.
-
- To do this I make use of with_override, and override the
- delete_breakpoints proc with a dummy proc which does nothing.
-
- By reverting the GDB changes in commit 7dd38e31d67c I have confirmed
- that even after my changes in this commit, the test still fails. But
- with the fixes in commit 7dd38e31d67c, this test now passed using the

- gdb: defer warnings when loading separate debug files
- Currently, when GDB loads debug information from a separate debug
- file, there are a couple of warnings that could be produced if things
- go wrong.
-
- In find_separate_debug_file_by_buildid (build-id.c) GDB can give a
- warning if the separate debug file doesn't include any actual debug
- information, and in separate_debug_file_exists (symfile.c) we can warn
- if the CRC checksum in the separate debug file doesn't match the
- checksum in the original executable.
-
- The problem here is that, when looking up debug information, GDB will
- try several different approaches, lookup by build-id, lookup by
- debug-link, and then a lookup from debuginfod. GDB can potentially
- give a warning from an earlier attempt, and then succeed with a later
- attempt. In the cases I have run into this is primarily a warning
- about some out of date debug information on my machine, but then GDB
- finds the correct information using debuginfod. This can be confusing
- to a user, they will see warnings from GDB when really everything is
- working just fine.
-
- For example:
-
- warning: the debug information found in "/usr/lib/debug//lib64/ld-2.32.so.debug" \
- does not match "/lib64/ld-linux-x86-64.so.2" (CRC mismatch).
-
- This diagnostic was printed on Fedora 33 even when the correct
- debuginfo was downloaded.
-
- In this patch I propose that we defer any warnings related to looking
- up debug information from a separate debug file. If any of the
- approaches are successful then GDB will not print any of the warnings.
- As far as the user is concerned, everything "just worked". Only if
- GDB completely fails to find any suitable debug information will the
- warnings be printed.
-
- The crc_mismatch test compiles two executables: crc_mismatch and
- crc_mismatch-2 and then strips them of debuginfo creating separate
- debug files. The test then replaces crc_mismatch-2.debug with
- crc_mismatch.debug to trigger "CRC mismatch" warning. A local
- debuginfod server is setup to supply the correct debug file, now when
- GDB looks up the debug info no warning is given.
-
- The build-id-no-debug-warning.exp is similar to the previous test. It
- triggers the "separate debug info file has no debug info" warning by
- replacing the build-id based .debug file with the stripped binary and
- then loading it to GDB. It then also sets up local debuginfod server
- with the correct debug file to download to make sure no warnings are
- emitted.

- gas/ppc: Additional tests for DFP instructions
- I noticed that some of the Power6 DFP instructions were not covered by

- The existing gas/testsuite/gas/ppc/power6.d test is called:

- And does cover some of the DFP instructions. But, given the number of

- gdb/dwarf: dump cooked index contents in cooked_index_functions::dump
- As I am investigating a crash I see with the cooked index, I thought it
- would be useful to have a way to dump the index contents. For those not
- too familiar with it (that includes me), it can help get a feel of what
- it contains and how it is structured.
-
- The cooked_index_functions::dump function is called as part of the
- "maintenance print objfiles" command. I tried to make the output
- well structured and indented to help readability, as this prints a lot
- of text.
-
- The dump function first dumps all cooked index entries, like this:
-
- [25] ((cooked_index_entry *) 0x621000121220)
- name: __ioinit
- canonical: __ioinit
- DWARF tag: DW_TAG_variable
- flags: 0x2 [IS_STATIC]
- DIE offset: 0x21a4
- parent: ((cooked_index_entry *) 0x6210000f9610) [std]
-
- Then the information about the main symbol:
-
- main: ((cooked_index_entry *) 0x621000123b40) [main]
-
- And finally the address map contents:
-
- [1] ((addrmap *) 0x6210000f7910)
-
- [0x0] ((dwarf2_per_cu_data *) 0)
- [0x118a] ((dwarf2_per_cu_data *) 0x60c000007f00)
- [0x1cc7] ((dwarf2_per_cu_data *) 0)
- [0x1cc8] ((dwarf2_per_cu_data *) 0x60c000007f00)
- [0x1cdf] ((dwarf2_per_cu_data *) 0)
- [0x1ce0] ((dwarf2_per_cu_data *) 0x60c000007f00)
-
- The display of address maps above could probably be improved, to show it
- more as ranges, but I think this is a reasonable start.
-
- Note that this patch depends on Pedro Alves' patch "enum_flags
- to_string" [1]. If my patch is to be merged before Pedro's series, I
- will cherry-pick this patch from his series and merge it before mine.

- enum_flags to_string
- This commit introduces shared infrastructure that can be used to
- implement enum_flags -> to_string functions. With this, if we want to
- support converting a given enum_flags specialization to string, we
- just need to implement a function that provides the enumerator->string
- mapping, like so:
-
- enum some_flag
- {
- SOME_FLAG1 = 1 << 0,
- SOME_FLAG2 = 1 << 1,
- SOME_FLAG3 = 1 << 2,
- };
-
- DEF_ENUM_FLAGS_TYPE (some_flag, some_flags);
-
- static std::string
- to_string (some_flags flags)
- {
- static constexpr some_flags::string_mapping mapping[] = {
- MAP_ENUM_FLAG (SOME_FLAG1),
- MAP_ENUM_FLAG (SOME_FLAG2),
- MAP_ENUM_FLAG (SOME_FLAG3),
- };
- return flags.to_string (mapping);
- }
-
- .. and then to_string(SOME_FLAG2 | SOME_FLAG3) produces a string like
- "0x6 [SOME_FLAG2 SOME_FLAG3]".
-
- If we happen to forget to update the mapping array when we introduce a
- new enumerator, then the string representation will pretty-print the
- flags it knows about, and then the leftover flags in hex (one single
- number). For example, if we had missed mapping SOME_FLAG2 above, we'd
- end up with:
-
- to_string(SOME_FLAG2 | SOME_FLAG3) => "0x6 [SOME_FLAG2 0x4]");
-
- Other than in the unit tests included, no actual usage of the
- functionality is added in this commit.

- Fix comparator bug in cooked index
- Simon pointed out that the cooked index template-matching patch
- introduced a failure in libstdc++ debug mode. In particular, the new
- code violates the assumption of std::lower_bound and std::upper_bound
- that the range is sorted with respect to the comparison.
-
- When I first debugged this, I thought the problem was unfixable as-is
- and that a second layer of filtering would have to be done. However,
- on irc, Simon pointed out that it could perhaps be solved if the
- comparison function were assured that one operand always came from the
- index, with the other always being the search string.
-
- This patch implements this idea.
-
- First, a new mode is introduced: a sorting mode for
- cooked_index_entry::compare. In this mode, strings are compared
- case-insensitively, but we're careful to always sort '<' before any
- other printable character. This way, two names like "func" and
- "func<param>" will be sorted next to each other -- i.e., "func1" will
- not be seen between them. This is important when searching.
-
- Second, the compare function is changed to work in a strcmp-like way.
- This makes it easier to test and (IMO) understand.
-
- Third, the compare function is modified so that in non-sorting modes,
- the index entry is always the first argument. This allows consistency
- in compares.
-
- I regression tested this in libstdc++ debug mode on x86-64 Fedora 36.
- It fixes the crash that Simon saw.
-
- This is v2. I believe it addresses the review comments, except for
- the 'enum class' change, as I mentioned in email on the list.

- gdb: provide const-correct versions of addrmap::find and addrmap::foreach
- Users of addrmap::find and addrmap::foreach that have a const addrmap
- should ideally receive const pointers to objects, to indicate they
- should not be modified. However, users that have a non-const addrmap
- should still receive a non-const pointer.
-
- To achieve this, without adding more virtual methods, make the existing
- find and foreach virtual methods private and prefix them with "do_".
- Add small non-const and const wrappers for find and foreach.
-
- Obviously, the const can be cast away, but if using static_cast
- instead of C-style casts, then the compiler won't let you cast
- the const away. I changed all the callers of addrmap::find and
- addrmap::foreach I could find to make them use static_cast.

- gdb: Add per-remote target variables for memory read and write config
- This patch adds per-remote target variables for the configuration of
- memory read- and write packet size. It is a further change to commit
- "gdb: Make global feature array a per-remote target array" to apply the
- fixme notes described in commit 5b6d1e4 "Multi-target support".
-
- The former global variables for that configuration are still available
- to allow the command line configuration for all future remote
- connections. Similar to the command line configuration of the per-
- remote target feature array, the commands
-
- - set remotewritesize (deprecated)
- - set remote memory-read-packet-size
- - set remote memory-write-packet-size
-
- will configure the current target (if available). If no target is
- available, the default configuration for future remote connections is
- adapted. The show command will display the current remote target's
- packet size configuration. If no remote target is selected, the default
- configuration for future connections will be shown.
-
- It is required to adapt the test gdb.base/remote.exp which is failing
- for --target_board=native-extended-gdbserver. With that board GDB
- connects to gdbserver at gdb start time. Due to this patch two loggings
- "The target may not be able to.." are shown if the command 'set remote
- memory-write-packet-size fixed' is executed while a target is connected
- for the current inferior. To fix this, the clean_restart command is
- moved to a later time point of the test. It is sufficient to be
- connected to the server when "runto_main" is executed. Now the
- connection time is similar to a testrun with
- --target_board=native-gdbserver.
-
- To allow the user to distinguish between the packet-size configuration
- for future remote connections and for the currently selected target, the
- commands' loggings are adapted.

-
- gdb: Make global feature array a per-remote target array
- This patch applies the appropriate FIXME notes described in commit 5b6d1e4
- "Multi-target support".
-
- "You'll notice that remote.c includes some FIXME notes. These refer to
- the fact that the global arrays that hold data for the remote packets
- supported are still globals. For example, if we connect to two
- different servers/stubs, then each might support different remote
- protocol features. They might even be different architectures, like
- e.g., one ARM baremetal stub, and a x86 gdbserver, to debug a
- host/controller scenario as a single program. That isn't going to
- work correctly today, because of said globals. I'm leaving fixing
- that for another pass, since it does not appear to be trivial, and I'd
- rather land the base work first. It's already useful to be able to
- debug multiple instances of the same server (e.g., a distributed
- cluster, where you have full control over the servers installed), so I
- think as is it's already reasonable incremental progress."
-
- Using this patch it is possible to configure per-remote targets'
- feature packets.
-
- Given the following setup for two gdbservers:
-
- ~~~~
- gdbserver --multi :1234
- gdbserver --disable-packet=vCont --multi :2345
- ~~~~
-
- Before this patch configuring of range-stepping was not possible for one
- of two connected remote targets with different support for the vCont
- packet. As one of the targets supports vCont, it should be possible to
- configure "set range-stepping". However, the output of GDB looks like:
-
- (gdb) target extended-remote :1234
- Remote debugging using :1234
- (gdb) add-inferior -no-connection
- [New inferior 2]
- Added inferior 2
- (gdb) inferior 2
- [Switching to inferior 2 [<null>] (<noexec>)]
- (gdb) target extended-remote :2345
- Remote debugging using :2345
- (gdb) set range-stepping on
- warning: Range stepping is not supported by the current target
- (gdb) inferior 1
- [Switching to inferior 1 [<null>] (<noexec>)]
- (gdb) set range-stepping on
- warning: Range stepping is not supported by the current target
- ~~~~
-
- Two warnings are shown. The warning for inferior 1 should not appear
- as it is connected to a target supporting the vCont package.
-
- ~~~~
- (gdb) target extended-remote :1234
- Remote debugging using :1234
- (gdb) add-inferior -no-connection
- [New inferior 2]
- Added inferior 2
- (gdb) inferior 2
- [Switching to inferior 2 [<null>] (<noexec>)]
- (gdb) target extended-remote :2345
- Remote debugging using :2345
- (gdb) set range-stepping on
- warning: Range stepping is not supported by the current target
- (gdb) inferior 1
- [Switching to inferior 1 [<null>] (<noexec>)]
- (gdb) set range-stepping on
- (gdb)
- ~~~~
-
- Now only one warning is shown for inferior 2, which is connected to
- a target not supporting vCont.
-
- The per-remote target feature array is realized by a new class
- remote_features, which stores the per-remote target array and
- provides functions to determine supported features of the target.
- A remote_target object now has a new member of that class.
-
- Each time a new remote_target object is initialized, a new per-remote
- target array is constructed based on the global remote_protocol_packets
- array. The global array is initialized in the function _initialize_remote
- and can be configured using the command line. Before this patch the
- command line configuration affected current targets and future remote
- targets (due to the global feature array used by all remote
- targets). This behavior is different and the configuration applies as
- follows:
-
- - If a target is connected, the command line configuration affects the
- current connection. All other existing remote targets are not
- affected.
-
- - If not connected, the command line configuration affects future
- connections.
-
- The show command displays the current remote target's configuration. If no
- remote target is selected the default configuration for future
- connections is shown.
-
- If we have for instance the following setup with inferior 2 being
- selected:
- ~~~~
- (gdb) info inferiors
- Num Description Connection Executable
- 1 <null> 1 (extended-remote :1234)
- * 2 <null> 2 (extended-remote :2345)
- ~~~~
-
- Before this patch, if we run 'set remote multiprocess-feature-packet', the
- following configuration was set:
- The feature array of all remote targets (in this setup the two connected
- targets) and all future remote connections are affected.
-
- After this patch, it will be configured as follows:
- The feature array of target with port :2345 which is currently selected
- will be configured. All other existing remote targets are not affected.
- The show command 'show remote multiprocess-feature-packet' will display
- the configuration of target with port :2345.
-
- Due to this configuration change, it is required to adapt the test
- "gdb/testsuite/gdb.multi/multi-target-info-inferiors.exp" to configure the
- multiprocess-feature-packet before the connections are created.
-
- To inform the gdb user about the new behaviour of the 'show remote
- PACKET-NAME' commands and the new configuration impact for remote
- targets using the 'set remote PACKET-NAME' commands the commands'
- outputs are adapted. Due to this change it is required to adapt each
- test using the set/show remote 'PACKET-NAME' commands.

- gdb/tui: avoid extra refresh_window on vertical scroll
- While working on the previous couple of patches I noticed that when I
- scroll the src and asm windows vertically, I get two refresh_window
- calls.
-
- The two calls can be traced back to
- tui_source_window_base::update_source_window_as_is, in here we call
- show_source_content, which calls refresh_window, and then
- update_exec_info, which also calls refresh_window.
-
- In this commit I propose making the refresh_window call in
- update_exec_info optional. In update_source_window_as_is I'll then
- call update_exec_info before calling show_source_content, and pass a
- flag to update_exec_info to defer the refresh.
-
- There are places where update_exec_info is used without any subsequent
- refresh_window call (e.g. when a breakpoint is updated), so
- update_exec_info does not to call refresh_window in some cases, which
- is why I'm using a flag to control the refresh.
-
- With this changes I'm now only seeing a single refresh_window call for
- each vertical scroll.
-
- There should be no user visible changes after this commit.

-
- gdb/tui: avoid extra refresh_window on horizontal scroll
- While working on the previous patches I noticed that in some cases I
- was seeing two calls to tui_source_window_base::refresh_window when
- scrolling the window horizontally.
-
- The two calls would trigger in for the tui-disasm-long-lines.exp test
- when the pad needed to be refilled. The two called both come from
- tui_source_window_base::show_source_content. The first call is nested
- within check_and_display_highlight_if_needed, while the second call is
- done directly at the end of show_source_content.
-
- The check_and_display_highlight_if_needed is being used to draw the
- window box to the window, this is needed here because
- show_source_content is what gets called when the window needs
- updating, e.g. after a resize. We could potentially do the boxing in
- refresh_window, but then we'd be doing it each time we scroll, even
- though the box doesn't need changing in this case.
-
- However, we can move the check_and_display_highlight_if_needed to be
- the last thing done in show_source_content, this means that we can
- rely on the refresh_window call within it to be our single refresh
- call.
-
- There should be no user visible changes after this commit.

- gdb/tui: rewrite of tui_source_window_base to handle very long lines
- This commit addresses an issue that is exposed by the test script
- gdb.tui/tui-disasm-long-lines.exp, that is, tui_source_window_base
- does not handle very long lines.
-
- The problem can be traced back to the newpad call in
- tui_source_window_base::show_source_content, this is where we allocate
- a backing pad to hold the window content.
-
- Unfortunately, there appears to be a limit to the size of pad that can
- be allocated, and the gdb.tui/tui-disasm-long-lines.exp test goes
- beyond this limit. As a consequence the newpad call fails and returns
- nullptr.
-
- It just so happens that the reset of the tui_source_window_base code
- can handle the pad being nullptr (this happens anyway when the window
- is first created, so we already depend on nullptr handling), so all
- that happens is the source window displays no content.
-
- ... well, sort of ... something weird does happen in the command
- window, we seem to see a whole bunch of blank lines. I've not
- bothered to track down exactly what's happening there, but it's some
- consequence of GDB attempting to write content to a WINDOW* that is
- nullptr.
-
- Before explaining my solution, I'll outline how things currently work:
-
- Consider we have the following window content to display:
-
- aaaaaaaaaa
- bbbbbbbbbbbbbbbbbbbb
- ccccccccccccccc
-
- the longest line here is 20 characters. If our display window is 10
- characters wide, then we will create a pad that is 20 characters wide,
- and then copy the lines of content into the pad:
-
- .--------------------.
- |aaaaaaaaaa |
- |bbbbbbbbbbbbbbbbbbbb|
- |ccccccccccccccc |
- .--------------------.
-
- Now we will copy a 10 character wide view into this pad to the
- display, our display will then see:
-
- .----------.
- |aaaaaaaaaa|
- |bbbbbbbbbb|
- |cccccccccc|
- .----------.
-
- As the user scrolls left and right we adjust m_horizontal_offset and
- use this to select which part of the pad is copied onto the display.
-
- The benefit of this is that we only need to copy the content to the
- pad once, which includes processing the ansi escape sequences, and
- then the user can scroll left and right as much as they want
- relatively cheaply.
-
- The problem then, is that if the longest content line is very long,
- then we try to allocate a very large pad, which can fail.
-
- What I propose is that we allow both the pad and the display view to
- scroll. Once we allow this, then it becomes possible to allocate a
- pad that is smaller than the longest display line. We then copy part
- of the content into the pad. As the user scrolls the view left and
- right GDB will continue to copy content from the pad just as it does
- right now. But, when the user scrolls to the edge of the pad, GDB
- will copy a new block of content into the pad, and then update the
- view as normal. This all works fine so long as the maximum pad size
- is larger than the current window size - which seems a reasonable
- restriction, if ncurses can't support a pad of a given size it seems
- likely it will not support a display window of that size either.
-
- If we return to our example above, but this time we assume that the
- maximum pad size is 15 characters, then initially the pad would be
- loaded like this:
-
- .---------------.
- |aaaaaaaaaa |
- |bbbbbbbbbbbbbbb|
- |ccccccccccccccc|
- .---------------.
-
- Notice that the last 5 characters from the 'b' line are no longer
- included in the pad. There is still enough content though to fill the
- 10 character wide display, just as we did before.
-
- The pad contents remain unchanged until the user scrolls the display
- right to this point:
-
- .----------.
- |aaaaa |
- |bbbbbbbbbb|
- |cccccccccc|
- .----------.
-
- Now, when the user scrolls right once more GDB spots that the user has
- reached the end of the pad, and the pad contents are reloaded, like
- this:
-
- .---------------.
- |aaaaa |
- |bbbbbbbbbbbbbbb|
- |cccccccccc |
- .---------------.
-
- The display can now be updated from the pad again just like normal.
-
- With this change in place the gdb.tui/tui-disasm-long-lines.exp test
- now correctly loads the assembler code, and we can scroll around as
- expected.
-
- Most of the changes are pretty mundane, just updating to match the
- above. One interesting change though is the new member function
- tui_source_window_base::puts_to_pad_with_skip. This replaces direct
- calls to tui_puts when copying content to the pad.
-
- The content strings contain ansi escape sequences. When these strings
- are written to the pad these escape sequences are translated into
- ncurses attribute setting calls.
-
- Now however, we sometimes only write a partial string to the pad,
- skipping some of the leading content. Imagine then that we have a
- content line like this:
-
- "\033[31mABCDEFGHIJKLM\033[0m"
-
- Now the escape sequences in this content mean that the actual
- content (the 'ABCDEFGHIJKLM') will have a red foreground color.
-
- If we want to copy this to the pad, but skip the first 3 characters,
- then what we expect is to have the pad contain 'DEFGHIJKLM', but this
- text should still have a red foreground color.
-
- It is this problem that puts_to_pad_with_skip solves. This function
- skips some number of printable characters, but processes all the
- escape sequences. This means that when we do start printing the
- actual content the content will have the expected attributes.

- gdb/tui: make m_horizontal_offset private
- I noticed that tui_source_window_base::m_horizontal_offset was
- protected, but could be made private, so lets do that.
-
- This makes more sense in the context of a later commit where I plan to
- add another member variable that is similar to m_horizontal_offset.
- The new member variable could also be private.
-
- So I had to choose, place the new member variable next to
- m_horizontal_offset making it protected, but grouping similar
- variables together, or make m_horizontal_offset private, and then add
- the new variable as private too.
-
- I chose to make m_horizontal_offset private, which is this commit.

- gdb/tui: disable tui mode when an assert triggers
- When an assert triggers in tui mode the output is not great, the
- internal backtrace that is generated is printed directly to the file
- descriptor for gdb_stderr, and, as a result, does not currently format
- itself correctly - the output uses only '\n' at the end of each line,
- and so, when the terminal is in raw mode, the cursor does not return
- to the start of each line after the '\n'.
-
- This is mostly fixable, we could update bt-utils.c to use '\r\n'
- instead of just '\n', and this would fix most of the problems. The
- one we can't easily fix is if/when GDB is built to use execinfo
- instead of libbacktrace, in this case we use backtrace_symbols_fd to
- print the symbols, and this function only uses '\n' as the line
- terminator. Fixing this would require switching to backtrace_symbols,
- but that API uses malloc, which is something we're trying to
- avoid (this code is called when GDB hits an error, so ideally we don't
- want to rely on malloc).
-
- However, the execinfo code is only used when libbacktrace is not
- available (or the user specifically disables libbacktrace) so maybe we
- can ignore that problem...
-
- ... but there is another problem. When the backtrace is printed in
- raw mode, it is possible that the backtrace fills the screen. With
- the terminal in raw mode we don't have the ability to scroll back,
- which means we loose some of the backtrace, which isn't ideal.
-
- In this commit I propose that we should disable tui mode whenever we
- handle a fatal signal, or when we hit the internal error code
- path (e.g. when an assert triggers). With this done then we don't
- need to update the bt-utils.c code, and the execinfo version of the
- code (using backtrace_symbols_fd) works just fine. We also get the
- ability to scroll back to view the error message and all of the
- backtrace, assuming the users terminal supports scrolling back.
-
- The only downside I see with this change is if the tui_disable call
- itself causes an error for some reason, or, if we handle a single at a
- time when it is not safe to call tui_disable, in these cases the extra
- tui_disable call might cause GDB to loose the original error.
-
- However, I think (just from personal experience) that the above two
- issues are pretty rare and the benefits from this change far out
- weighs the possible drawbacks.

- gdb/tui: improve errors from tui focus command
- This commit improves (I think) the errors from the tui focus command.
- There are a number of errors that can be triggered by the focus
- command, they include:
-
- (1) Window name "NAME" is ambiguous
-
- (2) Unrecognized window name "NAME"
-
- (3) Window "NAME" cannot be focused
-
- Error (1) is triggered when the user gives a partial window name, and
- the name matches multiple windows in the current layout.
-
- It is worth noting that the ambiguity must be within the current
- layout; if the partial name matches one window in the current layout,
- and one or more windows not in the current layout, then this is not
- ambiguous, and focus will shift to the matching window in the current
- layout.
-
- This error was not previous being tested, but in this commit I make
- use of the Python API to trigger and test this error.
-
- Error (3) is simple enough, and was already being tested. This is
- triggered by something like 'focus status'. The named window needs to
- be present in the current layout, and non-focusable in order to
- trigger the error.
-
- Error (2) is what I'd like to improve in this commit. This error
- triggers if the name the user gives doesn't match any window in the
- current layout. Even if GDB does know about the window, but the
- window isn't in the current layout, then GDB will say it doesn't
- recognize the window name.
-
- In this commit I propose to to split this error into three different
- errors. These will be:
-
- (a) Unrecognized window name "NAME"
-
- (b) No windows matching "NAME" in the current layout
-
- (c) Window "NAME" is not in the current layout
-
- Error (a) is the same as before, but will now only trigger if GDB
- doesn't know about window NAME at all. If the window is known, but
- not in the current layout then one of the other errors will trigger.
-
- Error (b) will trigger if NAME is ambiguous for multiple windows that
- are not in the current layout. If NAME identifies a single window in
- the current layout then that window will continue to be selected, just
- as it currently is. Only in the case where NAME doesn't identify a
- window in the current layout do we then check all the other known
- windows, if NAME matches multiple of these, then (b) is triggered.
-
- Finally, error (c) is used when NAME uniquely identifies a single
- window that is not in the current layout.
-
- The hope with these new errors is that the user will have a better
- understanding of what went wrong. Instead of GDB claiming to not know
- about a window, the mention of the current layout will hint to the
- user that they should first switch layouts.
-
- There are tests included for all the new errors.

- x86: move reg_operands adjustment
- Ideally we'd do away with this somewhat questionable adjustment (leaving
- i.types[] untouched). That's non-trivial though as it looks, so only
- - move the logic into process_operands(), putting it closer to related
- logic and eliminating a conditional for operand-less insns,
- - make it consistent (i.e. also affect %xmm0), eliminating an ugly
- special case later in the function.
-
- x86: drop dead SSE2AVX-related code
- All (there are just two) SSE2AVX templates with %xmm0 as first operand
- also specify VEX3SOURCES. Hence there's no need for an "else" to the

- FAIL: gdb.dap/basic-dap.exp: instructions in disassemble output
-
- The problem is that the PC to disassemble is taken from the breakpoint
- insertion response, which happens before running. With a PIE
- executable, that PC is unrelocated, but the disassembly request happens
- after relocation.
-
- I chose to fix this by watching for a breakpoint changed event giving
- the new breakpoint address, and recording the address from there. I
- think this is an interesting way to fix it, because it adds a bit of
- test coverage, I don't think these events are checked right now.
-
- Other ways to fix it would be:
-
- - Get the address by doing a breakpoint insertion after the program is
- started, or some other way.
- - Do the disassembly by symbol instead of by address.
- - Do the disassembly before running the program.

- gdb/testsuite/dap: make dap_wait_for_event_and_check return preceding messages
- In the following patch, I change gdb.dap/basic-dap.exp such that after
- waiting for some event, it checks if it received another event
- meanwhile. To help with this, make dap_wait_for_event_and_check and
- _dap_dap_wait_for_event return a list with everything received before
- the event of interest. This is similar to what
- dap_check_request_and_response returns.

- gdb/testsuite/dap: pass around dicts instead of TON objects
- The DAP helper functions generally return TON objects. However, callers
- almost all immediately use ton::2dict to convert them to dicts, to
- access their contents. This commits makes things a bit simpler for them
- by having function return dicts directly instead.
-
- The downside is that the TON objects contain type information. For
- instance, a "2" in a TCL dict could have been the integer 2 or the
- string "2" in JSON. By converting to TCL dicts, we lose that
- information. If some tests specifically want to check the types of some
- fields, I think we can add intermediary functions that return TON
- objects, without having to complicate other callers who don't care.

- If an exception is thrown while sending a request or reading a response,

- This helps following what happens when reading gdb.log. The downside is

- is even more confusing. At least, the lines are prefix with >>>, so

- [gdb/testsuite] Add gdb.base/unwind-on-each-insn-{amd64,i386}.exp
- The gcc 4.4.x (and earlier) compilers had the problem that the unwind info in
- the epilogue was inaccurate.
-
- In order to work around this in gdb, epilogue unwinders were added with a
- higher priority than the dwarf unwinders in the amd64 and i386 targets:
- - amd64_epilogue_frame_unwind, and
- - i386_epilogue_frame_unwind.
-
- Subsequently, the epilogue unwind info problem got fixed in gcc 4.5.0.
-
- However, the epilogue unwinders prevented gdb from taking advantage of the
- fixed epilogue unwind info, so the scope of the epilogue unwinders was
- limited, bailing out for gcc >= 4.5.0.
-
- There was no regression test added for this preference scheme, so if we now
- declare epilogue unwind info from all gcc versions as trusted, no test will
- start failing.
-
- Fix this by adding an amd64 and i386 regression test for this.
-
- I have no gcc 4.4.x lying around, so I fabricated the assembly files by:
- - commenting out some .cfi directives to break the epilogue unwind info, and
- - hand-editing the producer info to 4.4.7 to activate the fix.

- Tested on x86_64-linux, target boards unix/{-m64,-m32}.

- gdb/arm: Use new dwarf2 function cache
- This patch resolves the performance issue reported in pr/29738 by
- caching the values for the stack pointers for the inner frame. By
- doing so, the impact can be reduced to checking the state and
- returning the appropriate value.
-
-2023-01-25 Torbjörn SVENSSON <torbjorn.svensson@foss.st.com>
-
- gdb: dwarf2 generic implementation for caching function data
- When there is no dwarf2 data for a register, a function can be called
- to provide the value of this register. In some situations, it might
- not be trivial to determine the value to return and it would cause a
- performance bottleneck to do the computation each time.
-
- This patch allows the called function to have a "cache" object that it
- can use to store some metadata between calls to reduce the performance
- impact of the complex logic.
-
- The cache object is unique for each function and frame, so if there are
- more than one function pointer stored in the dwarf2_frame_cache->reg
- array, then the appropriate pointer will be supplied (the type is not
- known by the dwarf2 implementation).
-
- dwarf2_frame_get_fn_data can be used to retrieve the function unique
- cache object.
- dwarf2_frame_allocate_fn_data can be used to allocate and retrieve the
- function unique cache object.

- There's no insn that modifies stack or frame pointer.

- 400614: d65f03c0 ret
- ...
- such that the stack pointer (sp) is modified.
-
- [ Note btw that we're seeing the effects of -momit-leaf-frame-pointer, with

- ...
- 0000000000400604 <foo>:

- 400618: d65f03c0 ret
- ...
- such that also the frame pointer (x29) is modified. ]
-
- Having made foo more complex, we now run into the following fail on
- x86_64/-m32:
- ...
- FAIL: gdb.base/unwind-on-each-insn.exp: instruction 1: $sp_value == $main_sp
- ....
-
- The problem is that the stack pointer has changed inbetween the sampling of

- gdb/tui: convert if/error to an assert
- While working on the previous commit, I realised that there was an
- error in tui_set_focus_command that could never be triggered.
-
- Since the big tui rewrite (adding dynamic layouts) it is no longer
- true that there is a tui_win_info object for every window at all
- times. We now only create a tui_win_info object for a particular
- window, when the window is part of the current layout. As a result,
- if we have a tui_win_info pointer, then the window must be visible
- inside tui_set_focus_command (this function calls tui_enable as its
- first action, which makes the current layout visible).
-
- The gdb.tui/tui-focus.exp test script exercises this area of code, and
- doesn't trigger the assert, nor do any of our other existing tui
- tests.

- gdb/testsuite/tui: more testing of the 'focus' command
- I noticed that we didn't have many tests of the tui 'focus' command,
- so I started adding some. This exposed a bug in GDB; we are able to
- focus windows that should not be focusable, e.g. the 'status' window.
-
- This is harmless until we then do 'focus next' or 'focus prev', along
- this code path we assert that the currently focused window is
- focusable, which obviously, is not always true, so GDB fails with an
- assertion error.
-
- The fix is simple; add a check to the tui_set_focus_command function
- to ensure that the selected window is focusable. If it is not then an
- error is thrown. The new tests I've added cover this case.

- Change gdb test suite's TERM setting
-
- In the above commit the TERM environment variable was changed to be
- 'dumb' by default, which means that tests, that previously activated
- tui mode, no longer do unless TERM is set to 'ansi'.
-
- As the gdb.tui/tui-nl-filtered-output.exp script didn't do this, the
- test stopped working. As the expect patterns in this script were
- pretty generic no tests actually started failing, and we never
- noticed.
-
- In this commit I update the test script to correctly activate our
- terminal emulator, the test continues to pass after this update, but
- now we are testing in tui mode.

- gdb/testsuite: update gdb.tui/tui-disasm-long-lines.exp

-
- In the above commit the TERM environment variable was changed to be
- 'dumb' by default, which means that tests, that previously activated
- tui mode, no longer do unless TERM is set to 'ansi'.
-
- As the gdb.tui/tui-disasm-long-lines.exp script didn't do this, the
- test stopped working. As the expect patterns in this script were
- pretty generic no tests actually started failing, and we never
- noticed.
-
- In this commit I update the script to use Term::clean_restart, which
- correctly sets TERM to 'ansi'. I've also added a check that the asm
- box does appear on the screen, which should indicate that tui mode has
- correctly activated.
-
- However, I also notice that GDB doesn't appear to fully work
- correctly. The test should display the disassembly for the test
- program, but it doesn't.
-
- The test is trying to disassemble some code that (deliberately) uses a
- very long symbol name, this eventually results in GDB entering
- tui_source_window_base::show_source_content and trying to allocate an
- ncurses pad in order to hold the current page of disassembler output.
-
- Unfortunately, due to the very long line, the call to newpad fails,
- meaning that tui_source_window_base::m_pad is nullptr. Luckily non of
- the following calls appear to crash when passed a nullptr, however,
- all the output that is written to the pad is lost, which is why we
- don't see any assembly code written to the screen.
-
- As the test history indicates that the script was originally checking
- for a crash in GDB when the long identifier was encountered, I think
- there is value in just leaving the test as it is for now, I have a fix
- for the issue of the newpad call failing, which I'll post in a follow
- up commit later.

- gdb/testsuite: extend gdb.tui/tui-layout.exp test script
- In passing I noticed that the gdb.tui/tui-layout.exp test script was a
- little strange, it tests the layout command multiple times, but never
- sets up our ANSI terminal emulator, so every layout command fails with
- a message about the terminal lacking the required abilities.
-
- It turns out that this was caused by this commit:
-
- commit 9162a27c5f5828240b53379d735679e2a69a9f41
- Date: Tue Nov 13 11:59:03 2018 -0700
-
- Change gdb test suite's TERM setting
-
- This was when we changed the testsuite to set the TERM environment
- variable to "dumb" by default.
-
- After this, any tui test that didn't set the terminal mode back to
- 'ansi' would fail to activate tui mode.
-
- For the tui-layout.exp test it just so happens that the test patterns
- are generic enough that the test continued to pass, even after this
- change.
-
- In this commit I have updated the test so we now check the layout
- command both with a 'dumb' terminal and with the 'ansi' terminal.
- When testing with the 'ansi' terminal, I have some limited validation
- that GDB correctly entered tui mode.
-
- I figured that it is probably worth having at least one test in the
- test suite that deliberately tries to enter tui mode in a dumb
- terminal, it would be sad if we one day managed to break GDB such that
- this caused a crash, and never noticed.

- [gdb/tdep, aarch64] Fix frame address of last insn
- Consider the test-case test.c, compiled without debug info:
- ...
- void
- foo (const char *s)
- {
- }
-
- int
- main (void)
- {
- foo ("foo");
- return 0;
- }
- ...
-
- Disassembly of foo:
- ...
- 0000000000400564 <foo>:
- 400564: d10043ff sub sp, sp, #0x10
- 400568: f90007e0 str x0, [sp, #8]
- 40056c: d503201f nop
- 400570: 910043ff add sp, sp, #0x10
- 400574: d65f03c0 ret
- ...
-
- Now, let's do "info frame" at each insn in foo, as well as printing $sp
- and $x29 (and strip the output of info frame to the first line, for brevity):
- ...
- $ gdb -q a.out

- 1: /x $sp = 0xfffffffff3a0
- 2: /x $x29 = 0xfffffffff3a0
- ...
-
- The "frame at" bit lists 0xfffffffff3a0 except at the last insn, where it
- lists 0xfffffffff3b0.
-
- The frame address is calculated here in aarch64_make_prologue_cache_1:
- ...
- unwound_fp = get_frame_register_unsigned (this_frame, cache->framereg);
- if (unwound_fp == 0)
- return;
-
- cache->prev_sp = unwound_fp + cache->framesize;
- ...
-
- For insns after the prologue, we have cache->framereg == sp and
- cache->framesize == 16, so unwound_fp + cache->framesize gives the wrong
- answer once sp has been restored to entry value by the before-last insn.
-
- Fix this by detecting the situation that the sp has been restored.
-
- This fixes PRs tdep/30010 and tdep/30011.

- [gdb/testsuite] Avoid using .eh_frame in gdb.base/unwind-on-each-insn.exp
- One purpose of the gdb.base/unwind-on-each-insn.exp test-case is to test the
- architecture-specific unwinders on foo, so unwind-on-each-insn-foo.c is
- compiled with nodebug, to prevent the dwarf unwinders from taking effect.
-
- For for instance gcc x86_64 though, -fasynchronous-unwind-tables is enabled by
- default, generating an .eh_frame section contribution which might enable the
- dwarf unwinders and bypass the architecture-specific unwinders.
-
- Currently, that happens to be not the case due to the current implementation
- of epilogue_unwind_valid, which assumes that in absence of debug info proving
- that the compiler is gcc >= 4.5.0, the .eh_frame contribution is invalid.
-
- That may change though, see PR30028, in which case
- gdb.base/unwind-on-each-insn.exp stops being a regression test for commit
- 49d7cd733a7 ("Change calculation of frame_id by amd64 epilogue unwinder").
-
- Fix this by making sure that we don't use .eh_frame info regardless of
- epilogue_unwind_valid, simply by not generating it using
- -fno-asynchronous-unwind-tables.
-
- Tested on x86_64-linux, target boards unix/{-m64,-m32}, using compilers
- gcc 7.5.0 and clang 13.0.1.

- [gdb/testsuite] Simplify gdb.base/unwind-on-each-insn.exp
- In test-case gdb.base/unwind-on-each-insn.exp, we try to determine the last
- disassembled insn in function foo.
-
- This in it self is fragile, as demonstrated by commit 91836f41e20 ("Powerpc
- fix for gdb.base/unwind-on-each-insn.exp").
-
- The use of the last disassembled insn in the test-case is to stop stepping in
- foo once reaching it.
-
- However, the intent is to stop stepping just before returning to main.
-
- There is no guarantee that the last disassembled insn:
- - is actually executed
- - is executed just before returning to main
- - is executed only once.
-
- Fix this by simplying the test-case to continue stepping till stepping out of
- foo.

- Tested on x86_64-linux.

- gdb: make frame_info_ptr auto-reinflatable
- This is the second step of making frame_info_ptr automatic, reinflate on
- demand whenever trying to obtain the wrapper frame_info pointer, either
- through the get method or operator->. Make the reinflate method
- private, it is used as a convenience method in those two.
-
- Add an "is_null" method, because it is often needed to know whether the

-
- Make m_ptr mutable, so that it's possible to reinflate const

- the logical state of the object, because we re-create it on demand. I
- believe this is the right use case for mutable.

- gdb: make user-created frames reinflatable
- This patch teaches frame_info_ptr to reinflate user-created frames
- (frames created through create_new_frame, with the "select-frame view"
- command).
-
- Before this patch, frame_info_ptr doesn't support reinflating
- user-created frames, because it currently reinflates by getting the
- current target frame (for frame 0) or frame_find_by_id (for other
- frames). To reinflate a user-created frame, we need to call
- create_new_frame, to make it lookup an existing user-created frame, or
- otherwise create one.
-
- So, in prepare_reinflate, get the frame id even if the frame has level
- 0, if it is user-created. In reinflate, if the saved frame id is user
- create it, call create_new_frame.
-
- In order to test this, I initially enhanced the gdb.base/frame-view.exp
- test added by the previous patch by setting a pretty-printer for the
- type of the function parameters, in which we do an inferior call. This
- causes print_frame_args to not reinflate its frame (which is a
- user-created one) properly. On one machine (my Arch Linux one), it
- properly catches the bug, as the frame is not correctly restored after
- printing the first parameter, so it messes up the second parameter:
-
- frame
- #0 baz (z1=hahaha, z2=<error reading variable: frame address is not available.>) at /home/simark/src/binutils-gdb/gdb/testsuite/gdb.base/frame-view.c:40

- (gdb) FAIL: gdb.base/frame-view.exp: with_pretty_printer=true: frame again

- However, on another machine (my Ubuntu 22.04 one), it just passes fine,
- without the appropriate fix. I then thought about writing a selftest
- for that, it's more reliable. I left the gdb.base/frame-view.exp pretty

- gdb: make it possible to restore selected user-created frames
- I would like to improve frame_info_ptr to automatically grab the

-
- Here, we create a custom frame for thread 1 (using the stack from thread
- 2, for convenience):
-
- (gdb) select-frame view 0x7ffff7cc3f80 0x5555555551a2
-
- The first calls to "frame" looks good:
-
- (gdb) frame
- #0 thread_func (p=0x7ffff7d4e630) at /home/simark/src/binutils-gdb/gdb/testsuite/gdb.base/frame-view.c:42
- 42 foo (11);
-
- But not the second one:
-
- (gdb) frame
- #0 0x00007ffff7d4b4b6 in ?? () from /usr/lib/libc.so.6
-
- This second "frame" command shows the current target frame instead of
- the user-created frame.
-
- It's not totally clear how the "select-frame view" feature is expected
- to behave, especially since it's not tested. I heard accounts that it
- used to be possible to select a frame like this and do "up" and "down"
- to navigate the backtrace starting from that frame. The fact that
- create_new_frame calls frame_unwind_find_by_frame to install the right
- unwinder suggest that it used to be possible. But that doesn't work
- today:
-
- (gdb) select-frame view 0x7ffff7cc3f80 0x5555555551a2
- (gdb) up
- Initial frame selected; you cannot go up.
- (gdb) down
- Bottom (innermost) frame selected; you cannot go down.
-
- and "backtrace" always shows the actual thread's backtrace, it ignores
- the user-created frame:
-
- (gdb) bt
- #0 0x00007ffff7d4b4b6 in ?? () from /usr/lib/libc.so.6
- #1 0x00007ffff7d50403 in ?? () from /usr/lib/libc.so.6

-
- I don't want to address all the `select-frame view` issues , but I think
- we can agree that the "frame" command changing the selected frame, as
- shown above, is a bug. I would expect that command to show the
- currently selected frame and not change it.
-
- This happens because of the scoped_restore_selected_frame object in
- print_frame_args. The frame information is saved in the constructor
- (the backtrace below), and restored in the destructor.

-
- Since the user-created frame has level 0 (identified by the saved level
- -1), lookup_selected_frame just reselects the target's current frame,
- and the user-created frame is lost.
-
- My goal here is to fix this particular problem.
-
- Currently, select_frame does not set selected_frame_id and
- selected_frame_level for frames with level 0. It leaves them at
- null_frame_id / -1, indicating to restore_selected_frame to use the
- target's current frame. User-created frames also have level 0, so add a
- special case them such that select_frame saves their selected id and
- level.
-
- save_selected_frame does not need any change.
-
- Change the assertion in restore_selected_frame that checks `frame_level
- != 0` to account for the fact that we can restore user-created frames,
- which have level 0.
-
- Finally, change lookup_selected_frame to make it able to re-create
- user-created frame_info objects from selected_frame_level and
- selected_frame_id.
-
- Add a minimal test case for the case described above, that is the
- "select-frame view" command followed by the "frame" command twice. In
- order to have a known stack frame to switch to, the test spawns a second
- thread, and tells the first thread to use the other thread's top frame.

- gdb: add user-created frames to stash
- A subsequent patch makes it possible for frame_info_ptr to reinflate
- user-created frames. If two frame_info_ptr objects wrapping the same
- user-created frame_info need to do reinflation, we want them to end up
- pointing to the same frame_info instance, and not create two separate
- frame_infos. Otherwise, GDB gets confused down the line, as the state
- kept in one frame_info object starts differing from the other
- frame_info.
-
- Achieve this by making create_new_frame place the user-created frames in
- the frame stash. This way, when the second frame_info_ptr does
- reinflation, it will find the existing frame_info object, created by the
- other frame_info_ptr, in the frame stash.
-
- To make the frame stash differentiate between regular and user-created
- frame infos which would otherwise be equal, change frame_addr_hash and
- frame_id::operator== to account for frame_id::user_created_p.
-
- I made create_new_frame look up existing frames in the stash, and only
- create one if it doesn't find one. The goal is to avoid the
- "select-frame view"/"info frame view"/"frame view" commands from
- overriding existing entries into the stash, should the user specify the
- same frame more than once. This will also help in the subsequent patch
- that makes frame_info_ptr capable of reinflating user-created frames.

- GDB/testsuite: Expand for character string limiting options
- Modify test cases that verify the operation of the array element limit
- with character strings such that they are executed twice, once with the
- `set print characters' option set to `elements' and the limit controlled
- with the `set print elements' option, and then again with the limit
- controlled with the `set print characters' option instead. Similarly
- with the `-elements' and `-characters' options for the `print' command.
- Additionally verify that said `print' command options combined yield the
- expected result.
-
- Verify correct $_gdb_setting and $_gdb_setting_str values for the `print
- characters' setting, in particular the `void' value for the `elements'
- default, which has no corresponding integer value exposed.
-
- Add Guile and Python coverage for the `print characters' GDB setting.
-
- There are new tests for Ada and Pascal, as the string printing code for
- these languages is different than the generic string printing code used
- by other languages. Modula2 also has different string printing code,
- but (a) this is similar to Pascal, and (b) there are no existing modula2
- tests written in Modula2, so I'm not sure how I'd even test the Modula2
- string printing.

-
- GDB: Add a character string limiting option
- This commit splits the `set/show print elements' option into two. We
- retain `set/show print elements' for controlling how many elements of an
- array we print, but a new `set/show print characters' setting is added
- which is used for controlling how many characters of a string are
- printed.
-
- The motivation behind this change is to allow users a finer level of
- control over how data is printed, reflecting that, although strings can
- be thought of as arrays of characters, users often want to treat these
- two things differently.
-
- For compatibility reasons by default the `set/show print characters'
- option is set to `elements', which makes the limit for character strings
- follow the setting of the `set/show print elements' option, as it used
- to. Using `set print characters' with any other value makes the limit
- independent from the `set/show print elements' setting, however it can
- be restored to the default with the `set print characters elements'
- command at any time.
-
- A corresponding `-characters' option for the `print' command is added,
- with the same semantics, i.e. one can use `elements' to make a given
- `print' invocation follow the limit of elements, be it set with the
- `-elements' option also given with the same invocation or taken from the
- `set/show print elements' setting, for characters as well regardless of
- the current setting of the `set/show print characters' option.
-
- The GDB changes are all pretty straightforward, just changing references
- to the old 'print_max' to use a new `get_print_max_chars' helper which
- figures out which of the two of `print_max' and `print_max_chars' values
- to use.
-
- Likewise, the documentation is just updated to reference the new setting
- where appropriate.
-
- To make people's life easier the message shown by `show print elements'
- now indicates if the setting also applies to character strings:
-
- (gdb) set print characters elements
- (gdb) show print elements
- Limit on string chars or array elements to print is 200.
- (gdb) set print characters unlimited
- (gdb) show print elements
- Limit on array elements to print is 200.
- (gdb)
-
- and the help text shows the dependency as well:
-
- (gdb) help set print elements
- Set limit on array elements to print.
- "unlimited" causes there to be no limit.
- This setting also applies to string chars when "print characters"
- is set to "elements".
- (gdb)
-
- In the testsuite there are two minor updates, one to add `-characters'
- to the list of completions now shown for the `print' command, and a bare
- minimum pair of checks for the right handling of `set print characters'
- and `show print characters', copied from the corresponding checks for
- `set print elements' and `show print elements' respectively.

-
- GDB: Allow arbitrary keywords in integer set commands
- Rather than just `unlimited' allow the integer set commands (or command
- options) to define arbitrary keywords for the user to use, removing
- hardcoded arrangements for the `unlimited' keyword.
-
- Remove the confusingly named `var_zinteger', `var_zuinteger' and
- `var_zuinteger_unlimited' `set'/`show' command variable types redefining
- them in terms of `var_uinteger', `var_integer' and `var_pinteger', which
- have the range of [0;UINT_MAX], [INT_MIN;INT_MAX], and [0;INT_MAX] each.
-
- Following existing practice `var_pinteger' allows extra negative values
- to be used, however unlike `var_zuinteger_unlimited' any number of such
- values can be defined rather than just `-1'.
-
- The "p" in `var_pinteger' stands for "positive", for the lack of a more
- appropriate unambiguous letter, even though 0 obviously is not positive;
- "n" would be confusing as to whether it stands for "non-negative" or
- "negative".
-
- Add a new structure, `literal_def', the entries of which define extra
- keywords allowed for a command and numerical values they correspond to.
- Those values are not verified against the basic range supported by the
- underlying variable type, allowing extra values to be allowed outside
- that range, which may or may not be individually made visible to the
- user. An optional value translation is possible with the structure to
- follow the existing practice for some commands where user-entered 0 is
- internally translated to UINT_MAX or INT_MAX. Such translation can now
- be arbitrary. Literals defined by this structure are automatically used
- for completion as necessary.
-
- So for example:
-
- const literal_def integer_unlimited_literals[] =
- {
- { "unlimited", INT_MAX, 0 },
- { nullptr }
- };
-
- defines an extra `unlimited' keyword and a user-visible 0 value, both of
- which get translated to INT_MAX for the setting to be used with.
-
- Similarly:
-
- const literal_def zuinteger_unlimited_literals[] =
- {
- { "unlimited", -1, -1 },
- { nullptr }
- };
-
- defines the same keyword and a corresponding user-visible -1 value that
- is used for the requested setting. If the last member were omitted (or
- set to `{}') here, then only the keyword would be allowed for the user
- to enter and while -1 would still be used internally trying to enter it
- as a part of a command would result in an "integer -1 out of range"
- error.
-
- Use said error message in all cases (citing the invalid value requested)
- replacing "only -1 is allowed to set as unlimited" previously used for
- `var_zuinteger_unlimited' settings only rather than propagating it to
- `var_pinteger' type. It could only be used for the specific case where
- a single extra `unlimited' keyword was defined standing for -1 and the
- use of numeric equivalents is discouraged anyway as it is for historical
- reasons only that they expose GDB internals, confusingly different
- across variable types. Similarly update the "must be >= -1" Guile error
- message.
-
- Redefine Guile and Python parameter types in terms of the new variable
- types and interpret extra keywords as Scheme keywords and Python strings
- used to communicate corresponding parameter values. Do not add a new
- PARAM_INTEGER Guile parameter type, however do handle the `var_integer'
- variable type now, permitting existing parameters defined by GDB proper,
- such as `listsize', to be accessed from Scheme code.
-
- With these changes in place it should be trivial for a Scheme or Python
- programmer to expand the syntax of the `make-parameter' command and the
- `gdb.Parameter' class initializer to have arbitrary extra literals along
- with their internal representation supplied.
-
- Update the testsuite accordingly.

- PowerPC: fix for gdb.reverse/finish-precsave.exp and gdb.reverse/finish-reverse.exp
- PR record/29927 - reverse-finish requires two reverse next instructions to
- reach previous source line
-
- PowerPC uses two entry points called the local entry point (LEP) and the
- global entry point (GEP). Normally the LEP is used when calling a
- function. However, if the table of contents (TOC) value in register 2 is
- not valid the GEP is called to setup the TOC before execution continues at
- the LEP. When executing in reverse, the function finish_backward sets the
- break point at the alternate entry point (GEP). However if the forward
- execution enters via the normal entry point (LEP), the reverse execution
- never sees the break point at the GEP of the function. Reverse execution
- continues until the next break point is encountered or the end of the
- recorded log is reached causing gdb to stop at the wrong place.
-
- This patch adds a new address to struct execution_control_state to hold the
- address of the alternate function start address, known as the GEP on
- PowerPC. The finish_backwards function is updated. If the stopping point
- is between the two entry points (the LEP and GEP on PowerPC), the stepping
- range is set to execute back to the alternate entry point (GEP on PowerPC).
- Otherwise, a breakpoint is inserted at the normal entry point (LEP on
- PowerPC).
-
- Function process_event_stop_test checks uses a stepping range to stop
- execution in the caller at the first instruction of the source code line.
- Note, on systems that only support one entry point, the address of the two
- entry points are the same.
-
- Test finish-reverse-next.exp is updated to include tests for the
- reverse-finish command when the function is entered via the normal entry
- point (i.e. the LEP) and the alternate entry point (i.e. the GEP).
-
- The patch has been tested on X86 and PowerPC with no regressions.

- Currently on X86, when executing the finish command in reverse, gdb does a
- single step from the first instruction in the callee to get back to the
- caller. GDB stops on the last instruction in the source code line where
- the call was made. When stopped at the last instruction of the source code
- line, a reverse next or step command will stop at the first instruction
- of the same source code line thus requiring two step/next commands to
- reach the previous source code line. It should only require one step/next
- command to reach the previous source code line.
-
- By contrast, a reverse next or step command from the first line in a
- function stops at the first instruction in the source code line where the
- call was made.
-
- This patch fixes the reverse finish command so it will stop at the first
- instruction of the source line where the function call was made. The
- behavior on X86 for the reverse-finish command now matches doing a
- reverse-next from the beginning of the function.
-
- The proceed_to_finish flag in struct thread_control_state is no longer
- used. This patch removes the declaration, initialization and setting of
- the flag.
-
- This patch requires a number of regression tests to be updated. Test
- gdb.mi/mi-reverse.exp no longer needs to execute two steps to get to the
- previous line. The gdb output for tests gdb.reverse/until-precsave.exp
- and gdb.reverse/until-reverse.exp changed slightly. The expected result in
- tests gdb.reverse/amd64-failcall-reverse.exp and
- gdb.reverse/singlejmp-reverse.exp are updated to the correct expected
- result.
-
- This patch adds a new test gdb.reverse/finish-reverse-next.exp to test the
- reverse-finish command when returning from the entry point and from the
- body of the function.
-
- The step_until proceedure in test gdb.reverse/step-indirect-call-thunk.exp
- was moved to lib/gdb.exp and renamed cmd_until.
-
- The patch has been tested on X86 and PowerPC to verify no additional
- regression failures occured.

- gdb/testsuite: expect SIGSEGV from top GDB spawn id
- When testing with the native-extended-gdbserver, I get:
-
- Thread 1 "xgdb" received signal SIGSEGV, Segmentation fault.
- 0x00007ffff6d828f2 in GC_find_limit_with_bound () from /usr/lib/x86_64-linux-gnu/libgc.so.1
- (gdb) FAIL: gdb.gdb/selftest.exp: xgdb is at prompt
-
- This is because the -re that is supposed to match this SIGSEGV is after
- `-i $inferior_spawn_id`. On native, the top and bottom GDB are on the
- same spawn id, so it ends up working. But with a gdbserver board,
- that's not the case. Move the SIGSEGV -re before the `-i
- $inferior_spawn_id` line, such that it matches what the top GDB outputs.
-
- Do the same fix in gdb.gdb/python-helper.exp.

- Fix parameter-less template regression in new DWARF reader
- PR c++/29896 points out a regression in the new DWARF reader. It does
- not properly handle a case like "break fn", where "fn" is a template
- function.
-
- This happens because the new index uses strncasecmp to compare.
- However, to make this work correctly, we need a custom function that
- ignores template parameters.
-
- This patch adds a custom comparison function and fixes the bug. A new
- test case is included.

- Move hash_entry and eq_entry into cooked_index::do_finalize
- I was briefly confused by the hash_entry and eq_entry functions in the
- cooked index. They are only needed in a single method, and that
- method already has a couple of local lambdas for a different hash
- table. So, it seemed cleaner to move these there as well.
-
- Don't erase empty indices in DWARF reader
- The DWARF reader has some code to remove empty indices. However, I
- think this code has been obsolete since some earlier changes to
- parallel_for_each. This patch removes this code.
-
- Avoid submitting empty tasks in parallel_for_each
- I found that parallel_for_each would submit empty tasks to the thread
- pool. For example, this can happen if the number of tasks is smaller
- than the number of available threads. In the DWARF reader, this
- resulted in the cooked index containing empty sub-indices. This patch
- arranges to instead shrink the result vector and process the trailing
- entries in the calling thread.

- gas: arm: Change warning message to not reference specific A-class architecture revision
- We noticed that a warning message about the use of scalar fp16
- instructions being UNPREDICTABLE when conditionalized in an IT
- block referenced the specific A-class architecture revision
- ARMv8.2-A.
- Many of these instructions are now also part of ARMv8.1-M, so
- the warning message had become misleading. Here we just change
- the message to not specify an architecture revision at all and
- update all testing accordingly. This was done with a simple
- find-n-replace within the binutils sources. No tests have
- regressed for the arm target.
-
- gas/ChangeLog:
-
- * config/tc-arm.c (do_scalar_fp16_v82_encode): Remove
- ARMv8.2-A from the warning message.

- gas: arm: Fix a further IT-predicated vcvt issue in the presense of MVE vcvtn
- Previously we had experienced issues with assembling a "VCVTNE" instruction
- in the presence of the MVE architecture extension, because it could be
- interpreted both as:
-
- * The base instruction VCVT + NE for IT predication when inside an IT block.
- * The MVE instruction VCVTN + E in the Else of a VPT block.
-
- Given a C reproducer of:
- ```
- int test_function(float value)
- {
- int ret_val = 10;
- if (value != 0.0)
- {
- ret_val = (int) value;
- }
- return ret_val;
- }
- ```
- GCC generates a VCVTNE instruction based on the `truncsisf2_vfp`
- pattern, which will look like:
- `vcvtne.s32.f32 s-reg, s-reg`
- This still triggers an error due to being misidentified as "vcvtn+e"
- Similar errors were found with other type combinations and instruction
- patterns (these have all been added to the testing of this patch).
-
- This class of errors was previously worked around by:
- https://sourceware.org/pipermail/binutils/2020-August/112728.html
- which addressed this by looking at the operand types, however,
- that isn't adequate to cover all the extra cases that have been
- found. Instead, we add some special-casing logic earlier when
- the instructions are parsed that is conditional on whether we are
- in a VPT block or not, when the instruction is parsed.
-
- gas/ChangeLog:
-
- * config/tc-arm.c (opcode_lookup): Add special vcvtn handling.
- * testsuite/gas/arm/mve-vcvtne-it-bad.l: Add further testing.

- libctf: update regexp to allow makeinfo to build document
- While trying to build gdb on latest openSUSE Tumbleweed, I noticed the
- following warning,
-
- checking for makeinfo... makeinfo --split-size=5000000
- configure: WARNING:
- *** Makeinfo is too old. Info documentation will not be built.
-
- then I checked the version of makeinfo, it said,
- ======
- $ makeinfo --version
- texi2any (GNU texinfo) 7.0.1
-

- License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>

- There is NO WARRANTY, to the extent permitted by law.
- ======
-
- After digging a little bit, it became quite obvious that a dot is
- missing in regexp that makes it impossible to match versions higher than
- 7.0, and here's the solution:
-
- - | egrep 'texinfo[^0-9]*(6\.[3-9]|[7-9][0-9])' >/dev/null 2>&1; then
- + | egrep 'texinfo[^0-9]*(6\.[3-9]|[7-9]\.[0-9])' >/dev/null 2>&1; then
-
- However, Eli pointed out that the solution above has another problem: it
- will stop working when Texinfo 10.1 will be released. Meanwhile, he
- suggested to solve this problem permanently. That is, we don't care
- about the minor version for Texinfo > 6.9, we only care about the major
- version.
-
- In this way, the problem will be resolved permanently, thanks to Eli.

- sim: modules.c: fix generation after recent refactors
- Add explicit arch-specific modules.c rules to keep the build from
- generating an incorrect common/modules.c. Otherwise the pattern
- rules would cascade such that it'd look for $arch/modules.o which
- turned into common/modules.c which triggered the gen rule.
-
- My local testing of this code didn't catch this bug because of how
- Automake manages .Po (dependency files) in incremental builds -- it
- was adding extra rules that override the pattern rules which caused
- the build to generate correct modules.c files. But when building
- from a cold cache, the pattern rules would force common/modules.c to
- be used leading to crashes at runtime.

-
- sim: igen: simplify build logic a little
- Now that all ports (that use igen) build in the top-level and depend
- on igen, we can move the conditional logic out of configure. We also
- switch from noinst_LIBRARIES to EXTRA_LIBRARIES so that the library
- is only built when needed (i.e. the igen tool is used).
-
- sim: build: drop depdir subdir hack
- Now that all the ports compile some C files in their arch dirs, Automake
- guarantees creating the depdir for us, so we can drop our configure hack.
-
- sim: common: simplify modules.c deps
- Now that all ports (other than ppc) build in the top-level, we don't
- need to expand all the modules.c targets as a recursive dep. Each
- port depends on their respective file now, and the ppc port doesn't
- use it at all.
-
- sim: common: move modules.c to source tracking
- This makes sure the arch-specific modules.c wildcard is matched and
- not the common/%.c so that we compile it correctly. It also makes
- sure each subdir has depdir logic enabled.
-
- sim: common: move libcommon.a dep to ppc code
- Rather than force this to be built ahead of time for all targets,
- move the dep to the ppc code since it's the only user of it now.
-
- sim: build: drop most recursive build deps
- Now that we build these objects in the top dir & generate modules.c
- there, we don't need to generate them all first -- we can let the
- normal dependency graph take care of building things in parallel.
-
- sim: common: move libcommon.a objects to sources
- This simplifies the build logic and avoids an Automake bug where the
- common_libcommon_a_OBJECTS variable isn't set in the arch libsim.a
- DEPENDENCIES for targets that, alphabetically, come before "common".
- We aren't affected by that bug with the current code, but as we move
- things out of SIM_ALL_RECURSIVE_DEPS and rely on finer dependencies,
- we will trip over it.
-
- sim: igen: simplify build dep
- Now that all ports (other than ppc) build in the top-level, we don't

- Use unsupported in 'require'
- This changes 'require' to use 'unsupported' rather than 'untested'.
- The latter doesn't really seem to be correct according to the DejaGNU
- documentation:
-
- Declares a test was not run. `untested' writes in the log file a
- message beginning with _UNTESTED_, appending the `message' argument.
- For example, you might use this in a dummy test whose only role is to
- record that a test does not yet exist for some feature.
-
- The example there, and some text elsewhere, is what makes me think
- this isn't a great fit. On the other hand, 'unsupported' says:
-
- Declares that a test case depends on some facility that does not exist
- in the testing environment.

- It's possible to make this fancier, but so far I haven't done so. One
- idea I had is to allow a predicate to have associated text to display
- on failure. Another is to convert the predicates that need a running

-
- The bug here is that dynamic types can't really be printed this way.
- This patch avoids the bug by disabling the "/o" feature in this case.

- because the Ada code doesn't support the "/o" feature (yet); and in

- ARM: Fix ld bloat introduced between binutils-2.38 and 2.39
- Since commit 9833b7757d24, "PR28824, relro security issues",
- ELF_MAXPAGESIZE matters much more, with regards to layout of
- the linked file. That commit fixed an actual bug, but also
- exposes a problem for targets were that value is too high.
-
- For example, for ARM(32, a.k.a. "Aarch32") specifically
- bfd_arch_arm, it's set to 64 KiB, making all Linux(/GNU)
- targets pay an extra amount of up to 60 KiB of bloat in
- DSO:s and executables. This matters when there are many
- such files, and where storage is expensive.
-
- It's *mostly* bloat when using a Linux kernel, as ARM(32) is
- a good example of an target where ELF_MAXPAGESIZE is set to
- an extreme value for an obscure corner-case. The ARM
- (32-bit) kernel has 4 KiB pages, has had that value forever,
- and can't be configured to any other value. The use-case is
- IIUC "Aarch32" emulation on an "Aarch64" (arm64) kernel, but
- not just that, but a setup where the Linux page-size is
- configured to something other than the *default* 4 KiB. Not
- sure there actually any such systems in use, again with
- both Aarch32 compatibility support and a non-4KiB pagesize,
- with all the warnings in the kernel config and requiring the
- "EXPERT" level set on.
-
- So, let's do like x86-64 in a2267dbfc9e1 "x86-64: Use only
- one default max-page-size" and set ELF_MAXPAGESIZE to 4096.
-
- bfd:
- * elf32-arm.c (ELF_MAXPAGESIZE): Always set to 0x1000.
-
-2023-01-12 Hans-Peter Nilsson <hp@axis.com>
-
- ld/testsuite: Adjust for ELF_MAXPAGESIZE 0x1000
- Many tests reflect a setting of ELF_MAXPAGESIZE to 64 KiB.
- With ELF_MAXPAGESIZE changed to 4 KiB, layout is sometimes
- different and symbols end up in other places. Avoid churn
- and regexpification of old test patterns by passing the
- max-page-size setting active at the time.

- libctf: ctf-link outdated input check faulty
- This check has a pair of faults which, combined, can lead to memory
- corruption. Firstly, it assumes that the values of the ctf_link_inputs
- hash are ctf_dict_t's: they are not, they are ctf_link_input_t's, a much
- shorter structure. So the flags check which is the core of this is
- faulty (but happens, by chance, to give the right output on most
- architectures, since usually we happen to get a 0 here, so the test that
- checks this usually passes). Worse, the warning that is emitted when
- the test fails is added to the wrong dict -- it's added to the input
- dict, whose warning list is never consumed, rendering the whole check
- useless. But the dict it adds to is still the wrong type, so we end up
- overwriting something deep in memory (or, much more likely,
- dereferencing a garbage pointer and crashing).
-
- Fixing both reveals another problem: the link input is an *archive*
- consisting of multiple members, so we have to consider whether to check
- all of them for the outdated-func-info thing we are checking here.
- However, no compiler exists that emits a mixture of members with this
- flag on and members with it off, and the linker always reserializes (and
- upgrades) such things when it sees them: so all members in a given
- archive must have the same value of the flag, so we only need to check
- one member per input archive.

- libctf: skip the testsuite from inside dejagnu
- The libctf testsuite uses Tcl try/catch to trap run_output errors. This
- is only supported in reasonably recent Tcls, so we detect the lack of
- try/catch and suppress the testsuite via an Automake conditional in its
- absence.
-
- But this turns out not to work: Automake produces a check-DEJAGNU target
- regardless of the value of this conditional and sticks it in an
- unconditionally-executed part of the makefile, so the testsuite gets
- executed anyway, and fails with a nasty-looking syntax error. We can't
- disable it by taking "dejagnu" out of AUTOMAKE_OPTIONS, because if you
- do that Automake stops you using RUNTEST, RUNTESTFLAGS and other
- variables users would expect to work.
-
- So move to disabling the testsuite from inside the testsuite itself,
- importing the value of the former Automake conditional as a Tcl variable
- and exiting very early in default.exp if it's false.

- Set _WIN32_WINNT in common.m4 configure check

- PR build/29966 points out that the GDB configure test for std::thread
- does not work in this situation, because _WIN32_WINNT is not defined
- in test program, and so <thread> seems to be fine.
-
- This patch is an attempt to fix the problem, by using the same setting
- for _WIN32_WINNT at configure time as is used at build time.
-

- [gdb/testsuite] Fix gdb.threads/dlopen-libpthread.exp for upstream glibc, again
- On an x86_64 laptop running ubuntu 22.04.1 with unity desktop:
- ...
- $ echo $XDG_CURRENT_DESKTOP
- Unity:Unity7:ubuntu
- ...
- I have:
- ...
- $ echo $LD_PRELOAD
- libgtk3-nocsd.so.0
- ...
- due to package gtk3-nocsd, a package recommended by unity-session.
-
- Consequently, for each exec these dependencies are pulled in, including
- libpthread.so.0:
- ...
- $ lddtree /lib/x86_64-linux-gnu/libgtk3-nocsd.so.0
- libgtk3-nocsd.so.0 => /lib/x86_64-linux-gnu/libgtk3-nocsd.so.0 (interpreter => none)
- libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2
- libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0
- libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6
- ld-linux-x86-64.so.2 => /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2
- ...
-
- So, while test-case gdb.threads/dlopen-libpthread.exp appears to run ok:
- ...
- # of expected passes 12
- # of unsupported tests 1
- ...
- with LD_PRELOAD="" we have instead:
- ...
- (gdb) PASS: gdb.threads/dlopen-libpthread.exp: continue to breakpoint: notify
- info sharedlibrary^M
- From To Syms Read Shared Object Library^M
- $hex $hex Yes /lib64/ld-linux-x86-64.so.2^M
- $hex $hex Yes /lib/x86_64-linux-gnu/libc.so.6^M
- $hex $hex Yes dlopen-libpthread.so^M
- (gdb) FAIL: gdb.threads/dlopen-libpthread.exp: libpthread.so found
- ...
-
- The problem is that libpthread is expected as dependency of
- dlopen-libpthread.so, but it's missing:
- ...
- $ lddtree dlopen-libpthread.so
- dlopen-libpthread.so => ./dlopen-libpthread.so (interpreter => none)
- libc.so.6 => $outputs/gdb.threads/dlopen-libpthread/dlopen-libpthread.so.d/libc.so.6
- ld-linux-x86-64.so.2 => /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2
- ...
- due to having glibc 2.35, which has libpthread integrated into libc.
-
- Fix this by:
- - adding a proc has_dependency
- - using [has_dependency $exec libpthread.so] as hint that libpthread
- may be preloaded
- - using ![has_dependency $shlib libpthread.so] to detect that
- the libpthread.so dependency is missing.
-
- Also add a missing return after untested "no matching probes".
-
- Tested on x86_64-linux, with and without LD_PRELOAD="".

- gas: Restore tc_pe_dwarf2_emit_offset for pe-aarch64
- Restores tc_pe_dwarf2_emit_offset in tc-aarch64.c, which is needed to
- make sure that DWARF offsets are encoded correctly (they're secrels in
- COFF). There were remnants of this there before, but they were removed
- by Jedidiah's original patch - presumably because we didn't yet have
- .secrel32.

- Add aarch64-w64-mingw32 target
- This adds a mingw target for aarch64, including windres and dlltool.
-
- Note that the old value of jmp_aarch64_bytes was wrong, and this does
- the same thing as MSVC does.

-
- Add .secrel32 for pe-aarch64
- Adds the .secrel32 pseudo-directive and its corresponding relocation.
-
- Add pe-aarch64 relocations
- This adds the remaining pe-aarch64 relocations, and gets them working.
- It also brings in the constant directives from ELF, as otherwise .word
- would be 2 rather than 4 bytes, and .xword and .dword wouldn't be
- defined.

- Fix size of external_reloc for pe-aarch64
- This patch series finishes off the work by Jedidiah Thompson, and adds
- support for creating aarch64 PE images.
-
- This should be essentially complete: I've used this to create a "hello
- world" Windows program in asm, and (with GCC patches) a UEFI program in
- C. I think the only things missing are the .secidx relocation, which is
- needed for PDBs, and the SEH pseudos used for C++ exceptions.
-
- This first patch fixes the size of RELSZ; I'm not sure why it was 14 in
- the first place. This is the size of the "Base Relocation Block" in
- https://learn.microsoft.com/en-us/windows/win32/debug/pe-format, and
- AFAIK should be 10 for everything.

- gdb/dwarf2: Fix 'rw_pieced_value' for values casted to different type.
- The 'rw_pieced_value' function is executed when fetching a (lazy)
- variable described by 'DW_OP_piece' or 'DW_OP_bit_piece'. The
- function checks the 'type' and 'enclosing_type' fields of the value
- for identity.
-
- * The 'type' field describes the type of a value.
- * In most cases, the 'enclosing_type' field is identical to the
- 'type' field.
- * Scenarios where the 'type' and 'enclosing_type' of an object
- differ are described in 'gdb/value.c'. Possible cases are:
- * If a value represents a C++ object, then the 'type' field
- gives the object's compile-time type. If the object actually
- belongs to some class derived from `type', perhaps with other
- base classes and additional members, then `type' is just a
- subobject of the real thing, and the full object is probably
- larger than `type' would suggest.
- * If 'type' is a dynamic class (i.e. one with a vtable), then GDB
- can actually determine the object's run-time type by looking at
- the run-time type information in the vtable. GDB may then elect
- to read the entire object.
- * If the user casts a variable to a different type
- (e.g. 'print (<type> []) <variable>'), the value's type is
- updated before reading the value.
-
- If a lazy value is fetched, GDB allocates space based on the enclosing
- type's length and typically reads the 'full' object. This is not
- implemented for pieced values and causes an internal error if 'type'
- and 'enclosing_type' of a value are not identical.
-
- However, GDB can read the value based on its type. Thus, this patch
- fixes the previously mentioned cases by removing the check for identity.

-
- This fixes the problem by moving bfd_init earlier, giving it a

- The objects are still compiled in the subdir, but the creation of the
- archive itself is in the top-level. This is a required step before we
- can move compilation itself up, and makes it easier to review.
-
- The downside is that each object compile is a recursive make instead of
- a single one. On my 4 core system, it adds ~100msec to the build per
- port, so it's not great, but it shouldn't be a big deal. This will go
- away of course once the top-level compiles objects.

- sim: build: drop support for subdir extra deps

- rework this to actually generate from the top-level.
-
- This currently builds off of the objects that go into the libsim.a as
- we don't build those from the top-level either. Once we migrate that
- up, we can switch this to the source files directly. It's a bit hacky
- overall, but makes it easier to migrate things in smaller chunks, and

- gdb/linespec.c: Fix missing source file during breakpoint re-set
- During breakpoint re-setting, the source_filename of an
- explicit_location_spec is used to lookup the symtabs associated with
- the breakpoint being re-set. This source_filename is compared with each
- known symtab filename in order to retrieve the breakpoint's symtabs.
-
- However the source_filename may have been originally copied from a
- symtab's fullname (the path where GDB found the source file) when the
- breakpoint was first created. If a breakpoint symtab's filename and
- fullname differ and there is no substitute-path rule that converts the
- fullname to the filename, this will cause a NOT_FOUND_ERROR to be thrown
- during re-setting.
-
- Fix this by using a symtab's filename to set the explicit_location_spec
- source_filename instead of the symtab's fullname.

- testsuite: handle icc and icpc deprecated remarks

- icc: remark #10441: The Intel(R) C++ Compiler Classic (ICC) is
- deprecated and will be removed from product release in the second half
- of 2023. The Intel(R) oneAPI DPC++/C++ Compiler (ICX) is the recommended
- compiler moving forward. Please transition to use this compiler. Use

- Copyright (C) 1985-2022 Intel Corporation. All rights reserved.
-
- As the testsuite compile fails when unexpected output by the compiler is
- seen this change in the compiler breaks all existing icc and icpc tests.
- This patch makes the gdb testsuite more forgiving by a) allowing the
- output of the remark when trying to figure out the compiler version
- and by b) adding '-diag-disable=10441' to the compile command whenever
- gdb_compile is called without the intention to detect the compiler.

- libsframe: adjust an incorrect check in flip_sframe
- When sframe_encoder_write needs to flip the buffer containing the SFrame
- section before writing, it is not necessary that the SFrame FDES are in

- FDEs will be sorted in the order of their start address. So, remove
- this incorrect assumption which is basically assuming that the last
- sfde_func_start_fre_off seen will help determine the end of the flipped
- buffer.
-
- The function now keeps track of the bytes_flipped and then compares it with
- the expected value. Also, added two more checks at appropriate places:

- gdb/c++: Detect ambiguous variables in imported namespaces
- When running gdb.cp/nsusing.cc and stopping at line 17, we can ask GDB
- to print x and get a compiler-dependent answer. Using gcc 12.2.1, GDB
- will print M::x, and using clang 16.0.0 prints N::x. Not only is this
- behavior confusing to users, it is also not consistent with compiler
- behaviors, which would warn that using x is ambiguous at this point.
-
- This commit makes GDB behavior consistent with compilers. it achieves
- this by making it so instead of exiting early when finding any symbol
- with the correct name, GDB continues searching through all include
- directives, storing all matching symbols in a relational map betwen the
- mangled name and the found symbols.
-
- If the resulting map has more than one entry, GDB says that the
- reference is ambiguous and lists all possibilities. Otherwise it returns
- the block_symbol structure for the desired symbol, or an empty struct if
- nothing was found.
-
- The commit also changes gdb.cp/nsusing.exp to test the ambiguous
- detection.

- gdbsupport: fix scoped_debug_start_end's move constructor
- I spotted a problem with scoped_debug_start_end's move constructor.
- When constructing a scoped_debug_start_end through it, it doesn't
- disable the moved-from object, meaning there are now two objects that
- will do the side-effects of decrementing the debug_print_depth global
- and printing the "end" message. Decrementing the debug_print_depth
- global twice is actually problematic, because the increments and
- decrements get out of sync, meaning we should hit this assertion, in
- theory:
-
- gdb_assert (debug_print_depth > 0);
-
- However, in practice, we don't see that. This is because despite the
- move constructor being required for this to compile:
-
- template<typename PT>
- static inline scoped_debug_start_end<PT &> ATTRIBUTE_NULL_PRINTF (6, 7)
- make_scoped_debug_start_end (PT &&pred, const char *module, const char *func,
- const char *start_prefix,
- const char *end_prefix, const char *fmt, ...)
- {
- va_list args;
- va_start (args, fmt);
- auto res = scoped_debug_start_end<PT &> (pred, module, func, start_prefix,
- end_prefix, fmt, args);
- va_end (args);
-
- return res;
- }
-
- ... it is never actually called, because compilers elide the move
- constructors all the way (the scoped_debug_start_end gets constructed
- directly in the instance of the top-level caller). To confirm this, I
- built GDB with -fno-elide-constructors, and now I see it:
-
- /home/simark/src/binutils-gdb/gdb/../gdbsupport/common-debug.h:147: internal-error: ~scoped_debug_start_end: Assertion `debug_print_depth > 0' failed.

-
- Fix this by adding an m_disabled field to scoped_debug_start_end, and

- gdb: make gdbarch_alloc take ownership of the tdep
- It's currently not clear how the ownership of gdbarch_tdep objects
- works. In fact, nothing ever takes ownership of it. This is mostly
- fine because we never free gdbarch objects, and thus we never free
- gdbarch_tdep objects. There is an exception to that however: when
- initialization fails, we do free the gdbarch object that is not going to
- be used, and we free the tdep too. Currently, i386 and s390 do it.
-
- To make things clearer, change gdbarch_alloc so that it takes ownership
- of the tdep. The tdep is thus automatically freed if the gdbarch is
- freed.
-
- Change all gdbarch initialization functions to pass a new gdbarch_tdep
- object to gdbarch_alloc and then retrieve a non-owning reference from
- the gdbarch object.
-
- Before this patch, the xtensa architecture had a single global instance
- of xtensa_gdbarch_tdep. Since we need to pass a dynamically allocated
- gdbarch_tdep_base instance to gdbarch_alloc, remove this global
- instance, and dynamically allocate one as needed, like we do for all
- other architectures. Make the `rmap` array externally visible and
- rename it to the less collision-prone `xtensa_rmap` name.

- gdb: use libbacktrace to create a better backtrace for fatal signals
-
- The code is trying to select between using libbacktrace or using the
- execinfo supplied backtrace API.
-
- First we check to see if we can use libbacktrace. If we can then we
- include some header files, and then set some defines to indicate that
- libbacktrace is being used.
-
- Then we check if execinfo is available, if it is then we include
- <execinfo.h> and set some alternative defines.
-
- In theory the second block of logic should not trigger if the first
- block (that uses libbacktrace) has also triggered, but we incorrectly
- check the define 'PRINT_BACKTRACE_ON_FATAL_SIGNAL' instead of checking
- for 'GDB_PRINT_INTERNAL_BACKTRACE_USING_LIBBACKTRACE', so the second
- block triggers more than it should. The
- 'PRINT_BACKTRACE_ON_FATAL_SIGNAL' define is not defined anywhere, this
- was a mistake in the original commit.
-
- In reality this is harmless, we include <execinfo.h> when we don't
- need too, but in by-utils.c the libbacktrace define is always checked
- for before the execinfo define, so we never actually end up using the
- execinfo path (when libbacktrace is available). But I figure its
- still worth cleaning this up.
-
- I've tested GDB in a "default" build where libbacktrace is used, and
- when configuring with --disable-libbacktrace which causes the execinfo
- backtrace API to be used instead, both still appear to work fine.
-
- There should be no user visible changes after this commit.

- Avoid unaligned pointer reads in PEP .idata section
- This is something I discovered when working on aarch64, though it's
- relevant to x86_64 too.
-
- The PE32+ imports are located in the .idata section, which starts off
- with a 20-byte structure for each DLL, containing offsets into the rest
- of the section. This is the Import Directory Table in
- https://learn.microsoft.com/en-us/windows/win32/debug/pe-format, which
- is a concatenation of the .idata$2 sections. This is then followed by an
- 20 zero bytes generated by the linker script, which calls this .idata$3.
-
- After this comes the .idata$4 entries for each function, which the
- loader overwrites with the function pointers. Because there's no padding
- between .idata$3 and .idata$4, this means that if there's an even number
- of DLLs, the function pointers won't be aligned on an 8-byte boundary.
-
- Misaligned reads are slower on x86_64, but this is more important on
- aarch64, as the e.g. `ldr x0, [x0, :lo12:__imp__func]` the compiler
- might generate requires __imp__func (the .idata$4 entry) to be aligned
- to 8 bytes. Without this you get IMAGE_REL_ARM64_PAGEOFFSET_12L overflow
- errors.

-
- Introduce value_at_non_lval
- In some cases, while a value might be read from memory, gdb should not
- record the value as being equivalent to that memory.
-
- In Ada, the inferior call code will call ada_convert_actual -- and
- here, if the argument is already in memory, that address will simply
- be reused. However, for a call like "f(g())", the result of "g" might
- be on the stack and thus overwritten by the call to "f".

- because a call to the old-style method will not work with any
- converted architectures (whereas calling the new-style method is will
- delegate when needed).

- This patch changes gdbarch.py so that the old gdbarch_return_value

- Fixing this requires letting the implementation of the gdbarch method
- resolve the type and return a value -- that is, both the contents and
- the new type.
-
- After an attempt at this, I realized I wouldn't be able to correctly
- update all implementations (there are ~80) of this method. So,
- instead, this patch adds a new method that falls back to the current
- method, and it updates gdb to only call the new method. This way it's
- possible to incrementally convert the architectures that I am able to
- test.

- [gdb/testsuite] Add xfail in gdb.arch/i386-pkru.exp
- On a x86_64-linux machine with pkru register, I run into:
- ...
- (gdb) PASS: gdb.arch/i386-pkru.exp: set pkru value
- info register pkru^M
- pkru 0x12345678 305419896^M
- (gdb) FAIL: gdb.arch/i386-pkru.exp: read value after setting value
- ...
-
- This is a regression due to kernel commit e84ba47e313d ("x86/fpu: Hook up PKRU
- onto ptrace()"). This is fixed by recent kernel commit 4a804c4f8356
- ("x86/fpu: Allow PKRU to be (once again) written by ptrace.").
-
- The regression occurs for kernel versions v5.14-rc1 (the first tag containing
- the regression) up to but excluding v6.2-rc1 (the first tag containing the fix).
-
- Fix this by adding an xfail for the appropriate kernel versions.

- [gdb] Fix segfault during inferior call to ifunc
- With a simple test-case:
- ...
- $ cat test.c
- char *p = "a";
- int main (void) {
- return strlen (p);
- }
- $ gcc -g test.c
- ...
- we run into this segfault:
- ...

-
- Temporary breakpoint 1, main () at test.c:4
- 4 return strlen (p);
-
- Fatal signal: Segmentation fault
- ...
-
- The strlen is an ifunc, and consequently during the call to
- call_function_by_hand_dummy for "p strlen (p)" another call
- to call_function_by_hand_dummy is used to resolve the ifunc.
-
- This invalidates the get_current_frame () result in the outer call.

- sim: sh: move some generated source files to built sources
- This should have been part of the previous commit 80636a54bcfa2bca3dc8f
- ("sim: build: move generated headers to built sources"), but they were
- missed because they're .c files effectively treated as .h files.
-
- sim: build: add var for tracking sim enable directly
- Rather than rely on SIM_SUBDIRS being set, add a dedicated variable

- SIM_SUBDIRS variable).
-

-
- sim: build: move generated headers to built sources
- Automake's automatic header deptracking has a bootstrap problem where
- it can't detect generated headers when compiling. We've been handling
- that by adding a custom SIM_ALL_RECURSIVE_DEPS variable, but that only
- works when building objects recursively in subdirs. As we move those
- out to the top-level, we don't have any recursive steps anymore. The
- Automake approach is to declare those headers in BUILT_SOURCES.
-
- This isn't completely foolproof as the Automake manual documents: it
- only activates for `make all`, not `make foo.o`, but that shouldn't be
- a huge limitation as it only affects the initial compile. After that,
- rebuilds should work fine.

- The rules seem to generate the same output as existing subdir cgen

- Initial implementation of Debugger Adapter Protocol
- The Debugger Adapter Protocol is a JSON-RPC protocol that IDEs can use
- to communicate with debuggers. You can find more information here:
-
- https://microsoft.github.io/debug-adapter-protocol/
-
- Frequently this is implemented as a shim, but it seemed to me that GDB
- could implement it directly, via the Python API. This patch is the
- initial implementation.
-
- DAP is implemented as a new "interp". This is slightly weird, because
- it doesn't act like an ordinary interpreter -- for example it doesn't
- implement a command syntax, and doesn't use GDB's ordinary event loop.
- However, this seemed like the best approach overall.
-
- To run GDB in this mode, use:
-
- gdb -i=dap
-
- The DAP code will accept JSON-RPC messages on stdin and print
- responses to stdout. GDB redirects the inferior's stdout to a new
- pipe so that output can be encapsulated by the protocol.
-
- The Python code uses multiple threads to do its work. Separate
- threads are used for reading JSON from the client and for writing JSON
- to the client. All GDB work is done in the main thread. (The first
- implementation used asyncio, but this had some limitations, and so I
- rewrote it to use threads instead.)
-
- This is not a complete implementation of the protocol, but it does
- implement enough to demonstrate that the overall approach works.
-
- There is a rudimentary test suite. It uses a JSON parser written in
- pure Tcl. This parser is under the same license as Tcl itself, so I
- felt it was acceptable to simply import it into the tree.
-
- There is also a bit of documentation -- just documenting the new
- interpreter name.

- [gdb/python] Fix gdb.python/py-finish-breakpoint2.exp for -m32
- [ Partial resubmission of an earlier submission by Andrew (
- https://sourceware.org/pipermail/gdb-patches/2012-September/096347.html ), so
- listing him as co-author. ]
-
- With x86_64-linux and target board unix/-m32, we have:
- ...
- (gdb) continue^M
- Continuing.^M
- Exception #10^M
- ^M
- Breakpoint 3, throw_exception_1 (e=10) at py-finish-breakpoint2.cc:23^M
- 23 throw new int (e);^M
- (gdb) FAIL: gdb.python/py-finish-breakpoint2.exp: \
- check FinishBreakpoint in catch()
- ...
-
- The following scenario happens:
- - set breakpoint in throw_exception_1, a function that throws an exception
- - continue
- - hit breakpoint, with call stack main.c:38 -> throw_exception_1
- - set a finish breakpoint
- - continue
- - hit the breakpoint again, with call stack main.c:48 -> throw_exception
- -> throw_exception_1
-
- Due to the exception, the function call did not properly terminate, and the
- finish breakpoint didn't trigger. This is expected behaviour.
-
- However, the intention is that gdb detects this situation at the next stop
- and calls the out_of_scope callback, which would result here in this test-case
- in a rather confusing "exception did not finish" message. So the problem is
- that this message doesn't show up, in other words, the out_of_scope callback
- is not called.
-
- [ Note that the fact that the situation is detected only at the next stop
- (wherever that happens to be) could be improved upon, and the earlier
- submission did that by setting a longjmp breakpoint. But I'm considering this
- problem out-of-scope for this patch. ]
-
- Note that the message does show up later, at thread exit:
- ...
- [Inferior 1 (process 20046) exited with code 0236]^M
- exception did not finish ...^M
- ...
-
- The decision on whether to call the out_of_scope call back is taken in
- bpfinishpy_detect_out_scope_cb, and the interesting bit is here:
- ...
- if (b->pspace == current_inferior ()->pspace
- && (!target_has_registers ()
- || frame_find_by_id (b->frame_id) == NULL))
- bpfinishpy_out_of_scope (finish_bp);
- ...
-
- In the case of the thread exit, the callback triggers because
- target_has_registers () == 0.
-
- So why doesn't the callback trigger in the case of the breakpoint?
-
- Well, the b->frame_id is the frame_id of the frame of main (the frame
- in which the finish breakpoint is supposed to trigger), so AFAIU
- frame_find_by_id (b->frame_id) == NULL will only be true once we've
- left main, at which point I guess we don't stop till thread exit.
-
- Fix this by saving the frame in which the finish breakpoint was created, and
- using frame_find_by_id () == NULL on that frame instead, such that we have:
- ...
- (gdb) continue^M
- Continuing.^M
- Exception #10^M
- ^M
- Breakpoint 3, throw_exception_1 (e=10) at py-finish-breakpoint2.cc:23^M
- 23 throw new int (e);^M
- exception did not finish ...^M
- (gdb) FAIL: gdb.python/py-finish-breakpoint2.exp: \
- check FinishBreakpoint in catch()
- ...
-
- Still, the test-case is failing because it's setup to match the behaviour that
- we get on x86_64-linux with target board unix/-m64:
- ...
- (gdb) continue^M
- Continuing.^M
- Exception #10^M
- stopped at ExceptionFinishBreakpoint^M
- (gdb) PASS: gdb.python/py-finish-breakpoint2.exp: \
- check FinishBreakpoint in catch()
- ...
-
- So what happens here? Again, due to the exception, the function call did not
- properly terminate, but the finish breakpoint still triggers. This is somewhat
- unexpected. This happens because it just so happens to be that the frame
- return address at which the breakpoint is set, is also the first instruction
- after the exception has been handled. This is a know problem, filed as
- PR29909, so KFAIL it, and modify the test-case to expect the out_of_scope
- callback.
-
- Also add a breakpoint after setting the finish breakpoint but before throwing
- the exception, to check that we don't call the out_of_scope callback too early.
-
- Tested on x86_64-linux, with target boards unix/-m32.

- Originally there was only one set of rules for generating code from

- when other multigen modes were added ("m16" & "multi") which also

- The m16 & multi targets generate itable once even when all the other

- generate itable with everything else out of convenience. This means
- flags are passed which don't affect the generated itable there.
-
- We can unify the itable generation by making sure the right -F/-M
- filter variables are passed down. Since there's already a dedicated
- rule & variable in the multi build mode, generalize that and switch
- the m16 & igen builds over too.
-
- I spent a lot of time staring at this code, building for diff mips
- targets, and exploring all the shell code paths. I think this is
- safe, but only time (and users) will really tell.

- This variable is only used to generate the itable files. In preparation

- chagnes here otherwise.

- sim: mips: drop unused micromips igen logic
- This code appears to be unused since it was first merged. When

- nothing sets SIM_MIPS_GEN=MICROMIPS in the config, all of this
- should be unreachable, so punt it to simplify. Further, the

- rely on sim_mips_micromips{,16}_{filter,machine} variables that

- The following test was failing on ppc64 and s390x:

- The offending stub was how we memcpy the FRE start address to the buffer
- (on-disk format). When the host is big-endian, the address of the

- value of the FRE start addr, not uint32_t sized value; we intend to copy

-
- sim: mips: move igen settings to top-level configure
- This is the last bit of logic that exists in the mips configure
- script, so move it to the top-level configure to kill it off.
- We still have to move the Makefile.in igen logic to local.mk,
- but this is a required first step for that.
-
- sim: mips: namespace igen configure vars
- To prepare moving this logic to the top-level configure, the vars
- need to be namespaced. Do that here to make it easier to review.
- Basically sim_xxx -> SIM_MIPS_XXX when a var is exported from the
- configure script to the Makefile, and sim_xxx -> sim_mips_xxx when
- the var is internal in the configure script.
-
- sim: mips: add igen recursive dep
- Make sure the igen tool exists before trying to compile the mips
- subdir. This happens to work when mips has a subconfigure, but
- hits a race condition when that is removed.
-
- sim: mips: drop unused ENGINE_ISSUE_POSTFIX_HOOK
- Nothing defines this, and it isn't called in all the engine runtimes,
- so drop it entirely to avoid confusion.

- sim: igen: drop move-if-changed usage
- Now that igen itself has this logic, drop these custom build rules
- to greatly simplify.
-
- sim: igen: support in-place updates ourself
- Every file that igen outputs is then processed with the move-if-changed
- shell script. This creates a lot of boilerplate in the build and not an
- insignificant amount of build-time overhead. Move the simple "is the file
- changed" logic into igen itself.
-

-
- gdb/testsuite: new test for recent dwarf reader issue
-
- A new test (gdb.base/signed-builtin-types.exp) was added that made use
- of 'info sources' to figure out if the debug information for a
- particular object file had been fully expanded or not. Unfortunately
- some lines of the 'info sources' output can be very long, this was
- observed on some systems where the debug information for the
- dynamic-linker was installed, in this case, the list of source files
- associated with the dynamic linker was so long it would cause expect's
- internal buffer to overflow.
-
- This commit switches from using 'info sources' to 'maint print
- objfile', the output from the latter command is more compact, but

- libsframe: fix a memory leak in sframe_decode
- sframe_decode () needs to malloc a temporary buffer of the same size as
- the input buffer (containing the SFrame section bytes) when endian
- flipping is needed. The decoder keeps the endian flipped contents in
- this buffer for its usage. This code is necessary when the target
- endianneess is not the same as host endianness.
-
- The malloc'd buffer needs to be kept track of, so that it can freed up in
- sframe_decoder_free () later.
-
- ChangeLog:
-
- * libsframe/sframe-impl.h (struct sframe_decoder_ctx): Add new
- member to keep track of the internally malloc'd buffer.
- * libsframe/sframe.c (sframe_decoder_free): Free it up.
- (sframe_decode): Update the reference to the buffer.

- FAIL: gdb.base/float128.exp: show configuration

- x86: correct what gets disabled by certain ".arch .no*"
- Features with prereqs as well as features with dependents cannot re-use
- CPU_*_MASK for the 3rd argument of SUBARCH() - they need to use
- CPU_ANY_*_MASK in order to avoid disabling too many (when there are
- prereqs) and/or too few (when there are dependents) features.
-
- Generally any CPU_ANY_*_MASK which exist should not remain unused.
- Exceptions are
- - FISTTP which has no corresponding entry in cpu_arch[],
- - IAMCU which is a base architecture and hence uses ARCH(), not
- SUBARCH() (only extensions can be disabled, but unlike for Cpu*86 it
- would be a little more clumsy to suppress generating of the #define).

-
- x86: re-work ISA extension dependency handling
- Getting both forward and reverse ISA dependencies right / consistent has
- been a permanent source of mistakes. Reduce what needs specifying
- manually to just the direct forward dependencies. Transitive forward
- dependencies as well as reverse ones are now derived and hence cannot go
- out of sync anymore (at least in the vast majority of cases; there are a
- few special cases to still take care of manually). In the course of this
- several CPU_ANY_*_FLAGS disappear, requiring adjustment to the
- assembler's cpu_arch[].
-
- Note that to retain the correct reverse dependency of AVX512F wrt
- AVX512-VP2INTERSECT, the latter has the previously missing AVX512F
- prereq added.
-
- Note further that to avoid adding the following undue prereqs:
- * ATHLON, K8, and AMDFAM10 gain CMOV and FXSR,
- * IAMCU gains 387,
- auxiliary table entries (including a colon-separated modifier) are
- introduced in addition to the ones representing from converting the old
- table.
-
- To maintain forward-only dependencies between AVX (XOP) and SSE* (SSE4a)
- (i.e. "nosse" not disabling AVX), reverse dependency tracking is
- artifically suppressed.
-
- As a side effect disabling of SSE or SSE2 will now also disable AES,
- PCLMUL, and SHA (respective elements were missing from
- CPU_ANY_SSE2_FLAGS).

- sim: build: hoist lists of common objects up
- In order to create libsim.a in the common dir, we need the list of

- gdb/c++: validate 'using' directives based on the current line
- When asking GDB to print a variable from an imported namespace, we only
- want to see variables imported in lines that the inferior has already
- gone through, as is being tested last in gdb.cp/nsusing.exp. However
- with the proposed change to gdb.cp/nsusing.exp, we get the following
- failures:
-
- (gdb) PASS: gdb.cp/nsusing.exp: continue to breakpoint: marker10 stop
- print x
- $9 = 911
- (gdb) FAIL: gdb.cp/nsusing.exp: print x, before using statement
- next
- 15 y += x;
- (gdb) PASS: gdb.cp/nsusing.exp: using namespace M
- print x
- $10 = 911
- (gdb) PASS: gdb.cp/nsusing.exp: print x, only using M
-
- Showing that the feature wasn't functioning properly, it just so
- happened that gcc ordered the namespaces in a convenient way.
- This happens because GDB doesn't take into account the line where the
- "using namespace" directive is written. So long as it shows up in the
- current scope, we assume it is valid.
-
- To fix this, add a new member to struct using_direct, that stores the
- line where the directive was written, and a new function that informs if
- the using directive is valid already.
-
- Unfortunately, due to a GCC bug, the failure still shows up. Compilers
- that set the declaration line of the using directive correctly (such as
- Clang) do not show such a bug, so the test includes an XFAIL for gcc
- code.
-
- Finally, because the final test of gdb.cp/nsusing.exp has turned into
- multiple that all would need XFAILs for older GCCs (<= 4.3), and that
- GCC is very old, if it is detected, the test just exits early.

- sim: sim_cpu: invert sim_cpu storage
- Currently all ports have to declare sim_cpu themselves in their

- dynamic makes it impossible to share common object code among
- multiple ports because the core data structure is always different.
-
- Let's invert this relationship: common code declares sim_cpu, and
- the port uses the new arch_data field for its per-cpu state.
-
- This is the first in a series of changes: it adds a define to select
- between the old & new layouts, then converts all the ports that don't
- need custom state over to the new layout. This includes mn10300 that,
- while it defines custom fields in its cpu struct, never uses them.

- gdb: fix command lookup in execute_command ()
- Commit b5661ff2 ("gdb: fix possible use-after-free when
- executing commands") used lookup_cmd_exact () to lookup
- command again after its execution to avoid possible
- use-after-free error.
-
- However this change broke test gdb.base/define.exp which
- defines a post-hook for subcommand ("target testsuite").
- In this case, lookup_cmd_exact () returned NULL because
- there's no command 'testsuite' in top-level commands.
-
- This commit fixes this case by looking up the command again
- using the original command line via lookup_cmd ().

- gprofng/testsuite: skip Java test without JDK
- There's no point in even trying the Java test when gprofng was built
- without Java support, and when the building of the constituents of the

- tests from "unresolved" to "unsupported", making the overall testsuite

- gprofng/testsuite: eliminate bogus casts

- gprofng/testsuite: correct line continuation in endcases.c

- The signal handling tests spend most of their time in the signal

- succeeding.
-

- bfd_get_relocated_section_contents allow NULL data buffer
- This patch removes the bfd_malloc in default_indirect_link_order and

- Re: The problem with warning in elf_object_p
- Commit 5aa0f10c424e added a per_xvec_warn array to provide support for
- warnings from elf_object_p (and a later patch for warnings from
- pe_bfd_object_p) to be cached and then only printed if the target
- matches. It was quite limited in the style of message supported, only
- one message could be printed, and didn't really meet the stated aim of
- only warning when a target matches: There are many other errors and
- warnings that can be emitted by functions called from elf_object_p.
-
- So this patch extends the error handler functions to support printing
- to a string buffer, extends per_xvec_warn to support multiple errors/
- warnings, and hooks this all into bfd_check_format_matches. If
- bfd_check_format_matches succeeds then any errors/warnings are printed
- for the matching target. If bfd_check_format_matches fails either due
- to no match or to multiple matches and only one target vector produced
- errors, then those errors are printed.

- Delay checking whether /proc/pid/mem is writable (PR gdb/29907)
- As of 1bcb0708f229 ("gdb/linux-nat: Check whether /proc/pid/mem is
- writable"), GDB checks if /proc/pid/mem is writable. This is done
- early at GDB startup, in order to get a consistent warning, instead of
- a warning that depends on whenever GDB writes to inferior memory.
-
- PR gdb/29907 points out that some build systems (like QEMU's,
- apparently) may call 'gdb --version' to check GDB's presence & its
- version on the system, and that Gentoo's build process has sandboxing
- which blocks the /proc/pid/mem access and thus GDB warns, which
- results in build fails.
-
- To help with that, this patch delays the /proc/pid/mem check until we
- start or attach to an inferior. Ends up potentially emiting a warning
- close where we already emit other ptrace- and /proc- related warnings,
- which just Feels Right.

- gdb: fix crash when getting the value of a label symbol
- When the source program contains a goto label, it turns out it's
- actually pretty hard for a user to find out more about that label.
- For example:
-
- (gdb) p some_label
- No symbol "some_label" in current context.
- (gdb) disassemble some_label
- No symbol "some_label" in current context.
- (gdb) x/10i some_label
- No symbol "some_label" in current context.
- (gdb) break some_label
- Breakpoint 2 at 0x401135: file /tmp/py-label-symbol-value.c, line 35.
-
- In all cases, some_label is a goto label within the current frame.
- Only placing a breakpoint on the label worked.
-
- This all seems a little strange to me, it feels like asking about a
- goto label would not be an unreasonable thing for a user to do.
-
- This commit doesn't fix any of the above issues, I mention them just
- to provide a little context for why the following issue has probably
- not been seen before.
-
- It turns out there is one way a user can access the symbol for a goto
- label, through the Python API:
-
- python frame = gdb.selected_frame()
- python frame_pc = frame.pc()
- python block = gdb.current_progspace().block_for_pc(frame_pc)
- python symbol,_ = gdb.lookup_symbol('some_label', block, gdb.SYMBOL_LABEL_DOMAIN)
- python print(str(symbol.value()))
- ../../src/gdb/findvar.c:204: internal-error: store_typed_address: Assertion `type->is_pointer_or_reference ()' failed.
-
- The problem is that label symbols are created using the
- builtin_core_addr type, which is a pure integer type.
-
- When GDB tries to fetch the value of a label symbol then we end up in
- findvar.c, in the function language_defn::read_var_value, in the
- LOC_LABEL case. From here store_typed_address is called to store the
- address of the label into a value object with builtin_core_addr type.
-
- The problem is that store_typed_address requires that the destination
- type be a pointer or reference, which the builtin_core_addr type is
- not.
-
- Now it's not clear what type a goto label address should have, but
- GCC has an extension that allows users to take the address of a goto
- label (using &&), in that case the result is of type 'void *'.
-
- I propose that when we convert the CORE_ADDR value to a GDB value
- object, we use builtin_func_ptr type instead of builtin_core_addr,
- this means the result will be of type 'void (*) ()'. The benefit of
- this approach is that when gdbarch_address_to_pointer is called the
- target type will be correctly identified as a pointer to code, which
- should mean any architecture specific adjustments are done correctly.
-
- We can then cast the new value to 'void *' type with a call to
- value_cast_pointer, this should not change the values bit
- representation, but will just update the type.
-
- After this asking for the value of a label symbol works just fine:
-
- (gdb) python print(str(symbol.value()))
- 0x401135 <main+35>
-
- And the type is maybe what we'd expect:
-
- (gdb) python print(str(symbol.value().type))
- void *

- [aarch64] Fix removal of non-address bits for PAuth
- PR gdb/28947
-
- The address_significant gdbarch setting was introduced as a way to remove
- non-address bits from pointers, and it is specified by a constant. This
- constant represents the number of address bits in a pointer.
-
- Right now AArch64 is the only architecture that uses it, and 56 was a
- correct option so far.
-
- But if we are using Pointer Authentication (PAuth), we might use up to 2 bytes
- from the address space to store the required information. We could also have
- cases where we're using both PAuth and MTE.
-
- We could adjust the constant to 48 to cover those cases, but this doesn't
- cover the case where GDB needs to sign-extend kernel addresses after removal
- of the non-address bits.
-
- This has worked so far because bit 55 is used to select between kernel-space
- and user-space addresses. But trying to clear a range of bits crossing the
- bit 55 boundary requires the hook to be smarter.
-
- The following patch renames the gdbarch hook from significant_addr_bit to
- remove_non_address_bits and passes a pointer as opposed to the number of
- bits. The hook is now responsible for removing the required non-address bits
- and sign-extending the address if needed.
-
- While at it, make GDB and GDBServer share some more code for aarch64 and add a
- new arch-specific testcase gdb.arch/aarch64-non-address-bits.exp.

- gdb: remove static buffer in command_line_input
- [I sent this earlier today, but I don't see it in the archives.
- Resending it through a different computer / SMTP.]
-
- The use of the static buffer in command_line_input is becoming
- problematic, as explained here [1]. In short, with this patch [2] that
- attempt to fix a post-hook bug, when running gdb.base/commands.exp, we
- hit a case where we read a "define" command line from a script file
- using command_command_line_input. The command line is stored in
- command_line_input's static buffer. Inside the define command's
- execution, we read the lines inside the define using command_line_input,
- which overwrites the define command, in command_line_input's static
- buffer. After the execution of the define command, execute_command does
- a command look up to see if a post-hook is registered. For that, it
- uses a now stale pointer that used to point to the define command, in
- the static buffer, causing a use-after-free. Note that the pointer in
- execute_command points to the dynamically-allocated buffer help by the
- static buffer in command_line_input, not to the static object itself,
- hence why we see a use-after-free.
-
- Fix that by removing the static buffer. I initially changed
- command_line_input and other related functions to return an std::string,
- which is the obvious but naive solution. The thing is that some callees
- don't need to return an allocated string, so this this an unnecessary
- pessimization. I changed it to passing in a reference to an std::string
- buffer, which the callee can use if it needs to return
- dynamically-allocated content. It fills the buffer and returns a
- pointers to the C string inside. The callees that don't need to return
- dynamically-allocated content simply don't use it.
-
- So, it started with modifying command_line_input as described above, all
- the other changes derive directly from that.
-
- One slightly shady thing is in handle_line_of_input, where we now pass a
- pointer to an std::string's internal buffer to readline's history_value
- function, which takes a `char *`. I'm pretty sure that this function
- does not modify the input string, because I was able to change it (with
- enough massaging) to take a `const char *`.
-
- A subtle change is that we now clear a UI's line buffer using a
- SCOPE_EXIT in command_line_handler, after executing the command.
- This was previously done by this line in handle_line_of_input:
-
- /* We have a complete command line now. Prepare for the next
- command, but leave ownership of memory to the buffer . */
- cmd_line_buffer->used_size = 0;
-
- I think the new way is clearer.

- libsframe asan: avoid generating misaligned loads
- There are two places where unaligned loads were seen on aarch64:
- - #1. access to the SFrame FRE stack offsets in the in-memory
- representation/abstraction provided by libsframe.
- - #2. access to the SFrame FRE start address in the on-disk representation
- of the frame row entry.
-
- For #1, we can fix this by reordering the struct members of
- sframe_frame_row_entry in libsframe/sframe-api.h.
-
- For #2, we need to default to using memcpy instead, and copy out the bytes
- to a location for output.
-
- SFrame format is an unaligned on-disk format. As such, there are other blobs
- of memory in the on-disk SFrame FRE that are on not on their natural
- boundaries. But that does not pose further problems yet, because the users
- are provided access to the on-disk SFrame FRE data via libsframe's
- sframe_frame_row_entry, the latter has its' struct members aligned on their
- respective natural boundaries (and initialized using memcpy).

- gdb: ensure all targets are popped before an inferior is destructed
- Now that the inferiors target_stack automatically manages target
- reference counts, we might think that we don't need to unpush targets
- when an inferior is deleted...
-
- ...unfortunately that is not the case. The inferior::unpush function
- can do some work depending on the type of target, so it is important
- that we still pass through this function.
-
- To ensure that this is the case, in this commit I've added an assert
- to inferior::~inferior that ensures the inferior's target_stack is
- empty (except for the ever present dummy_target).
-
- I've then added a pop_all_targets call to delete_inferior, otherwise
- the new assert will fire in, e.g. the gdb.python/py-inferior.exp test.

- gdb: remove the pop_all_targets (and friends) global functions
- This commit removes the global functions pop_all_targets,
- pop_all_targets_above, and pop_all_targets_at_and_above, and makes
- them methods on the inferior class.
-
- As the pop_all_targets functions will unpush each target, which
- decrements the targets reference count, it is possible that the target
- might be closed.
-
- Right now, closing a target, in some cases, depends on the current
- inferior being set correctly, that is, to the inferior from which the
- target was popped.
-
- To facilitate this I have used switch_to_inferior_no_thread within the
- new methods. Previously it was the responsibility of the caller to
- ensure that the correct inferior was selected.
-
- In a couple of places (event-top.c and top.c) I have been able to
- remove a previous switch_to_inferior_no_thread call.
-
- In remote_unpush_target (remote.c) I have left the
- switch_to_inferior_no_thread call as it is required for the
- generic_mourn_inferior call.

- gdb: have target_stack automate reference count handling
- This commit changes the target_stack class from using a C style array
- of 'target_ops *' to using a C++ std::array<target_ops_ref, ...>. The
- benefit of this change is that some of the reference counting of
- target_ops objects is now done automatically.
-
- This commit fixes a crash in gdb.python/py-inferior.exp where GDB
- crashes at exit, leaving a core file behind.
-
- The crash occurs in connpy_connection_dealloc, and is actually
- triggered by this assert:
-
- gdb_assert (conn_obj->target == nullptr);
-
- Now a little aside...
-
- ... the assert is never actually printed, instead GDB crashes due
- to calling a pure virtual function. The backtrace at the point of
- crash looks like this:
-
- #7 0x00007fef7e2cf747 in std::terminate() () from /lib64/libstdc++.so.6
- #8 0x00007fef7e2d0515 in __cxa_pure_virtual () from /lib64/libstdc++.so.6
- #9 0x0000000000de334d in target_stack::find_beneath (this=0x4934d78, t=0x2bda270 <the_dummy_target>) at ../../s>
- #10 0x0000000000df4380 in inferior::find_target_beneath (this=0x4934b50, t=0x2bda270 <the_dummy_target>) at ../.>
- #11 0x0000000000de2381 in target_ops::beneath (this=0x2bda270 <the_dummy_target>) at ../../src/gdb/target.c:3047
- #12 0x0000000000de68aa in target_ops::supports_terminal_ours (this=0x2bda270 <the_dummy_target>) at ../../src/gd>
- #13 0x0000000000dde6b9 in target_supports_terminal_ours () at ../../src/gdb/target.c:1112
- #14 0x0000000000ee55f1 in internal_vproblem(internal_problem *, const char *, int, const char *, typedef __va_li>
-
- Notice in frame #12 we called target_ops::supports_terminal_ours,
- however, this is the_dummy_target, which is of type dummy_target,
- and so we should have called dummy_target::supports_terminal_ours.
- I believe the reason we ended up in the wrong implementation of
- supports_terminal_ours (which is a virtual function) is because we
- made the call during GDB's shut-down, and, I suspect, the vtables
- were in a weird state.
-
- Anyway, the point of this patch is not to fix GDB's ability to
- print an assert during exit, but to address the root cause of the
- assert. With that aside out of the way, we can return to the main
- story...
-
- Connections are represented in Python with gdb.TargetConnection
- objects (or its sub-classes). The assert in question confirms that
- when a gdb.TargetConnection is deallocated, the underlying GDB
- connection has itself been removed from GDB. If this is not true then
- we risk creating multiple different gdb.TargetConnection objects for
- the same connection, which would be bad.
-
- To ensure that we have one gdb.TargetConnection object for each
- connection, the all_connection_objects map exists, this maps the
- process_stratum_target object (the connection) to the
- gdb.TargetConnection object that represents the connection.
-
- When a connection is removed in GDB the connection_removed observer
- fires, which we catch with connpy_connection_removed, this function
- then sets conn_obj->target to nullptr, and removes the corresponding
- entry from the all_connection_objects map.
-
- The first issue here is that connpy_connection_dealloc is being called
- as part of GDB's exit code, which is run after the Python interpreter
- has been shut down. The connpy_connection_dealloc function is used to
- deallocate the gdb.TargetConnection Python object. Surely it is
- wrong for us to be deallocating Python objects after the interpreter
- has been shut down.
-
- The reason why connpy_connection_dealloc is called during GDB's exit
- is that the global all_connection_objects map is still holding a
- reference to the gdb.TargetConnection object. When the map is
- destroyed during GDB's exit, the gdb.TargetConnection objects within
- the map can finally be deallocated.
-
- The reason why all_connection_objects has contents when GDB exits, and
- the reason the assert fires, is that, when GDB exits, there are still
- some connections that have not yet been removed from GDB, that is,
- they have a non-zero reference count.
-
- If we take a look at quit_force (top.c) you can see that, for each
- inferior, we call pop_all_targets before we (later in the function)
- call do_final_cleanups. It is the do_final_cleanups call that is
- responsible for shutting down the Python interpreter. The
- pop_all_targets calls should, in theory, cause all the connections to
- be removed from GDB.
-
- That this isn't working indicates that some targets have a non-zero
- reference count even after this final pop_all_targets call, and
- indeed, when I debug GDB, that is what I see.
-
- I tracked the problem down to delete_inferior where we do some house
- keeping, and then delete the inferior object, which calls
- inferior::~inferior.
-
- In neither delete_inferior or inferior::~inferior do we call
- pop_all_targets, and it is this missing call that means we leak some
- references to the target_ops objects on the inferior's target_stack.
-
- In this commit I will provide a partial fix for the problem. I say
- partial fix, but this will actually be enough to resolve the crash.
- In a later commit I will provide the final part of the fix.
-
- As mentioned at the start of the commit message, this commit changes
- the m_stack in target_stack to hold target_ops_ref objects. This
- means that when inferior::~inferior is called, and m_stack is
- released, we automatically decrement the target_ops reference count.
- With this change in place we no longer leak any references, and now,
- in quit_force the final pop_all_targets calls will release the final
- references. This means that the targets will be correctly closed at
- this point, which means the connections will be removed from GDB and
- the Python objects deallocated before the Python interpreter shuts
- down.
-
- There's a slight oddity in target_stack::unpush, where we std::move
- the reference out of m_stack like this:
-
- auto ref = std::move (m_stack[stratum]);
-
- the `ref' isn't used explicitly, but it serves to hold the
- target_ops_ref until the end of the scope while allowing the m_stack
- entry to be reset back to nullptr. The alternative would be to
- directly set the m_stack entry to nullptr, like this:
-
- m_stack[stratum] = nullptr;
-
- The problem here is that when we set the m_stack entry to nullptr we
- first decrement the target_ops reference count, and then set the array
- entry to nullptr.
-
- If the decrement means that the target_ops object reaches a zero
- reference count then the target_ops object will be closed by calling
- target_close. In target_close we ensure that the target being closed
- is not in any inferiors target_stack.
-
- As we decrement before clearing, then this check in target_close will
- fail, and an assert will trigger.
-
- By using std::move to move the reference out of m_stack, this clears
- the m_stack entry, meaning the inferior no longer contains the
- target_ops in its target_stack. Now when the REF object goes out of
- scope and the reference count is decremented, target_close can run
- successfully.
-
- I've made use of the Python connection_removed listener API to add a
- test for this issue. The test installs a listener and then causes
- delete_inferior to be called, we can then see that the connection is
- then correctly removed (because the listener triggers).

-
- gdb/remote: remove some manual reference count handling
- While working on some other target_ops reference count related code, I
- spotted that in remote.c we do some manual reference count handling,
- i.e. we call target_ops::incref and decref_target (which wraps
- target_ops::decref).
-
- I think it would be better to make use of gdb::ref_ptr to automate the
- reference count management.
-
- So, this commit updates scoped_mark_target_starting in two ways,
- first, I use gdb::ref_ptr to handle the reference counts. Then,
- instead of using the scoped_mark_target_starting constructor and
- destructor to set and reset the starting_up flag, I now use a
- scoped_restore_tmpl object to set and restore the flag.
-
- The above changes mean that the scoped_mark_target_starting destructor
- can be completely removed, and the constructor body is now empty.
-
- I've also fixed a typo in the class comment.
-
- The only change in behaviour after this commit is that previously we
- didn't care what the value of starting_up was, we just set it to true
- in the constructor and false in the destructor.
-
- Now, I assert that the flag is initially false, then set the flag true
- when the scoped_mark_target_starting is created.
-
- As the starting_up flag is initialized to false then, for the assert
- to fire, we would need to recursively enter
- remote_target::start_remote_1, which I don't think is something we
- should be doing, so I think the new assert is an improvement.

- gdb: add SYMBOL_LOOKUP_SCOPED_DEBUG_ENTER_EXIT
- After the previous commit converted symbol-lookup debug to use the new
- debug scheme, this commit adds SYMBOL_LOOKUP_SCOPED_DEBUG_ENTER_EXIT.
-
- The previous commit didn't add SYMBOL_LOOKUP_SCOPED_DEBUG_ENTER_EXIT
- because symbol-lookup debug is controlled by an 'unsigned int' rather
- than a 'bool' control variable, we use the numeric value to offer
- different levels of verbosity for symbol-lookup debug.
-
- The *_SCOPED_DEBUG_ENTER_EXIT mechanism currently relies on capturing
- a reference to the bool control variable, and evaluating the variable
- both on entry, and at exit, this is done in the scoped_debug_start_end
- class (see gdbsupport/common-debug.h).
-
- This commit templates scoped_debug_start_end so that the class can
- accept either a 'bool &' or an invokable object, e.g. a lambda
- function, or a function pointer.
-
- The existing scoped_debug_start_end and scoped_debug_enter_exit macros
- in common-debug.h are updated to support scoped_debug_enter_exit being
- templated, however, nothing outside of common-debug.h needs to change.
-
- I've then added SYMBOL_LOOKUP_SCOPED_DEBUG_ENTER_EXIT in symtab.h, and
- added a couple of token uses in symtab.c. I didn't want to add too
- much in this first commit, this is really about updating
- common-debug.h to support this new functionality.
-
- Within symtab.h I created a couple of global functions that can be
- used to query the status of the symbol_lookup_debug control variable,
- these functions are then used within the two existing macros:
-
- symbol_lookup_debug_printf
- symbol_lookup_debug_printf_v
-
- and also in the new SYMBOL_LOOKUP_SCOPED_DEBUG_ENTER_EXIT macro.

-
- - When the user does something like 'p sizeof(short)', then this is
- handled in c-exp.y, and results in a call to lookup_signed_type
- for the name "int". The "int" here is actually being looked up as
- the type for the result of the 'sizeof' expression,
-
- - In lookup_signed_type GDB first adds a 'signed' and looks for that
- type, so in this case 'signed int', and, if that lookup fails, GDB
- then looks up 'int',
-
- - The problem is that 'signed int' is not the canonical name for a
- signed int, so no builtin type with that name will be found, GDB
- will then go to each object file in turn looking for a matching
- type,
-
- - When checking each object file, GDB will first check the partial
- symtab to see if the full symtab should be expanded or not.
- Remember, at this point GDB is looking for 'signed int', there
- will be no partial symbols with that name, so GDB will not expand
- anything,
-
- - However, GDB checks each partial symbol using multiple languages,
- not just the current language (C in this case), so, when GDB
- checks using the C++ language, the symbol name is first
- canonicalized (the code that does this can be found
- lookup_name_info::language_lookup_name). As the canonical form of
- 'signed int' is just 'int', GDB then looks for any symbols with
- the name 'int', most partial symtabs will contain such a symbol,
- so GDB ends up expanding pretty much every symtab.
-
- The above commit fixes this by avoiding the use of non-canonical names
- with C, now the initial builtin type lookup will succeed, and GDB
- never even considers whether to expand any additional symtabs.
-
- The test case creates a library that includes char, short, int, and
- long types, and a test program that links against the library.
-
- In the test script we start the inferior, but don't allow it to
- progress far enough that the debug information for the library has
- been fully expanded yet.
-
- Then we evaluate some 'sizeof(TYPE)' expressions.
-
- In the buggy version of GDB this would cause the debug information
- for the library to be fully expanded, while in the fixed version of
- GDB this will not be the case.
-
- We use 'info sources' to determine if the debug information has been
- fully expanded or not.

- gdb/testsuite: fix readnow detection
- The following commit broke the readnow detection in the testsuite:
-
- commit dfaa040b440084dd73ebd359326752d5f44fc02c
- Date: Mon Mar 29 18:31:31 2021 -0600
-
- Remove some "OBJF_READNOW" code from dwarf2_debug_names_index
-
- The testsuite checks if GDB was started with the -readnow flag by
- using the 'maintenance print objfiles' command, and looking for the
- string 'faked for "readnow"' in the output. This is implemented in
- two helper procs `readnow` (gdb.exp) and `mi_readnow` (mi-support.exp).
-
- The following tests all currently depend on this detection:
-
- gdb.base/maint.exp
- gdb.cp/nsalias.exp
- gdb.dwarf2/debug-aranges-duplicate-offset-warning.exp
- gdb.dwarf2/dw2-stack-boundary.exp
- gdb.dwarf2/dw2-zero-range.exp
- gdb.dwarf2/gdb-index-nodebug.exp
- gdb.mi/mi-info-sources.exp
- gdb.python/py-symbol.exp
- gdb.rust/traits.exp
-
- The following test also includes detection of 'readnow', but does the
- detection itself by checking $::GDBFLAGS for the readnow flag:
-
- gdb.opt/break-on-_exit.exp
-
- The above commit removed from GDB the code that produced the 'faked
- for "readnow"' string, as a consequence the testsuite can no longer
- correctly spot when readnow is in use, and many of the above tests
- will fail (at least partially).
-
- When looking at the above tests, I noticed that gdb.rust/traits.exp
- does call `readnow`, but doesn't actually use the result, so I've
- removed the readnow call, this simplifies the next part of this patch
- as gdb.rust/traits.exp was the only place an extra regexp was passed
- to the readnow call.
-
- Next I have rewritten `readnow` to check the $GDBFLAGS for the
- -readnow flag, and removed the `maintenance print objfiles` check. At
- least for all the tests above, when using the readnow board, this is
- good enough to get everything passing again.
-
- For the `mi_readnow` proc, I changed this to just call `readnow` from
- gdb.exp, I left the mi_readnow name in place - in the future it might
- be the case that we want to do some different checks here.
-
- Finally, I updated gdb.opt/break-on-_exit.exp to call the `readnow`
- proc.
-
- With these changes, all of the tests listed above now pass correctly
- when using the readnow board.

- RISC-V: Add string length check for operands in AS
- The current AS accepts invalid operands due to miss of operands length check.
- For example, "e6" is an invalid operand in (vsetvli a0, a1, e6, mf8, tu, ma),
- but it's still accepted by assembler. In detail, the condition check "strncmp
- (array[i], *s, len) == 0" in arg_lookup function passes with "strncmp ("e64",
- "e6", 2)" in the case above. So the generated encoding is same as that of
- (vsetvli a0, a1, e64, mf8, tu, ma).
-
- This patch fixes issue above by prompting an error in such case and also adds
- a new testcase.

- Fix control-c handling on Windows
- As Hannes pointed out, the Windows target-async patches broke C-c
- handling there. Looking into this, I found a few oddities, fixed
- here.
-
- First, windows_nat_target::interrupt calls GenerateConsoleCtrlEvent.
- I think this event can be ignored by the inferior, so it's not a great
- way to interrupt. Instead, using DebugBreakProcess (or a more
- complicated thing for Wow64) seems better.
-
- Second, windows_nat_target did not implement the pass_ctrlc method.
- Implementing this lets us remove the special code to call
- SetConsoleCtrlHandler and instead integrate into gdb's approach to C-c
- handling. I believe that this should also fix the race that's
- described in the comment that's being removed.
-
- Initially, I thought a simpler version of this patch would work.
- However, I think what happens is that some other library (I'm not sure
- what) calls SetConsoleCtrlHandler while gdb is running, and this
- intercepts and handles C-c -- so that the gdb SIGINT handler is not
- called. C-break continues to work, presumably because whatever
- handler is installed ignores it.
-
- This patch works around this issue by ensuring that the gdb handler
- always comes first.

- [gdb/tdep] Fix s390_linux_nat_target::stopped_by_watchpoint
- On s390x-linux, I run into:
- ...
- (gdb) continue^M
- Continuing.^M
- breakpoint.c:5784: internal-error: bpstat_stop_status_nowatch: \
- Assertion `!target_stopped_by_watchpoint ()' failed.^M
- A problem internal to GDB has been detected,^M
- further debugging may prove unreliable.^M
- FAIL: gdb.threads/watchpoint-fork.exp: parent: singlethreaded: \
- breakpoint after the first fork (GDB internal error)
- ...
-
- What happens is the follow:
- - a watchpoint event triggers
- - the event is processed, s390_linux_nat_target::stopped_by_watchpoint is called and
- it returns true, as expected
- - the watchpoint event is reported by gdb, and gdb stops
- - we issue a continue command
- - a fork event triggers
- - the event is processed, and during processing that event
- s390_linux_nat_target::stopped_by_watchpoint is called again, and returns
- true
- - the assertion fails, because the function is expected to return false
-
- The function s390_linux_nat_target::stopped_by_watchpoint returns true the
- second time, because it looks at the exact same data that was looked at when
- it was called the first time, and that data hasn't changed.
-
- There's code in the same function that intends to prevent that from happening:
- ...
- /* Do not report this watchpoint again. */
- memset (&per_lowcore, 0, sizeof (per_lowcore));
- if (ptrace (PTRACE_POKEUSR_AREA, s390_inferior_tid (), &parea, 0) < 0)
- perror_with_name (_("Couldn't clear watchpoint status"));
- ...
- and that probably used to work for older kernels, but no longer does since
- linux kernel commit 5e9a26928f55 ("[S390] ptrace cleanup").
-
- Fix this by copying this:
- ...
- siginfo_t siginfo;
- if (!linux_nat_get_siginfo (inferior_ptid, &siginfo))
- return false;
- if (siginfo.si_signo != SIGTRAP
- || (siginfo.si_code & 0xffff) != TRAP_HWBKPT)
- return false;
- ...
- from aarch64_linux_nat_target::stopped_data_address and remove the
- obsolete watchpoint status clearing code.
-
- Tested on s390x-linux.

- gas: re-work line number tracking for macros and their expansions

- Note that macro invocation context is lost for any diagnostics issued

- is related to [part of] the present stack of locations). To maintain the

- [gdb/testsuite] Fix PR20630 regression test in gdb.base/printcmds.exp
- On s390x-linux, I run into:
- ...
- (gdb) print {unsigned char}{65}^M
- $749 = 0 '\000'^M
- (gdb) FAIL: gdb.base/printcmds.exp: print {unsigned char}{65}
- ...
-
- In contrast, on x86_64-linux, we have:
- ...
- (gdb) print {unsigned char}{65}^M
- $749 = 65 'A'^M
- (gdb) PASS: gdb.base/printcmds.exp: print {unsigned char}{65}
- ...
-
- The first problem here is that the test is supposed to be a regression test
- for PR20630, which can be reproduced (for an unfixed gdb) like this:
- ...
- (gdb) p {unsigned char[]}{0x17}
- gdbtypes.c:4641: internal-error: copy_type: \
- Assertion `TYPE_OBJFILE_OWNED (type)' failed.
- ...
- but it's not due to insufficient quoting (note the dropped '[]').
-
- That's easy to fix, but after that we have on s390 (big endian):
- ...
- (gdb) print {unsigned char[]}{65}^M
- $749 = ""^M
- ...
- and on x86_64 (little endian):
- ...
- (gdb) print {unsigned char[]}{65}^M
- $749 = "A"^M
- ...
-
- Fix this by using 0xffffffff, such that in both cases we have:
- ...
- (gdb) print {unsigned char[]}{0xffffffff}^M
- $749 = "\377\377\377\377"^M
- ...
-
- Tested on x86_64-linux and s390x-linux.

- The problem is that the test-case hard-codes expectations about endiannes by

- If we print 4 bytes, we have for s390x:

- gdb: fix possible use-after-free when executing commands
- In principle, `execute_command()` does following:
-
- struct cmd_list_element *c;
- c = lookup_cmd ( ... );
- ...
- /* If this command has been pre-hooked, run the hook first. */
- execute_cmd_pre_hook (c);
- ...
- /* ...execute the command `c` ...*/
- ...
- execute_cmd_post_hook (c);
-
- This may lead into use-after-free error. Imagine the command
- being executed is a user-defined Python command that redefines
- itself. In that case, struct `cmd_list_element` pointed to by
- `c` is deallocated during its execution so it is no longer valid
- when post hook is executed.
-
- To fix this case, this commit looks up the command once again
- after it is executed to get pointer to (possibly newly allocated)
- `cmd_list_element`.

- PR gas/29524
-
- Having templates with a suffix explicitly present has always been

-
- While moving the check, also generalize it to include all SIMD and VEX-

- x86: re-work insn/suffix recognition
- Having templates with a suffix explicitly present has always been

- a suitable template _and_ didn't itself already need to trim off a
- suffix to find a match at all. This requires error reporting adjustments
- (albeit luckily fewer than I was afraid might be necessary), as errors
- previously reported during matching now need deferring until after the
- 2nd pass (because, obviously, we must not emit any error if the 2nd pass
- succeeds). While also related to PR gas/29524, it was requested that
- move-with-sign-extend be left as broken as it always was.
-
- PR gas/29525
- Note that with the dropped CMPSD and MOVSD Intel Syntax string insn
- templates taking operands, mixed IsString/non-IsString template groups
- (with memory operands) cannot occur anymore. With that

- gas: sframe: fine tune the fragment fixup for SFrame func info
- SFrame function info is an unsigned 8-bit field comprising of the following
- (from LSB to MSB):
- - 4-bits: FRE type
- - 1-bit: FRE start address encoding
- - 3-bits: Unused
-
- At the moment, the most-significat 4-bits are zero (The FRE start
- address encoding of SFRAME_FDE_TYPE_PCINC has a value of zero, and the upper
- 3-bits are unused). So the current implementation works without this patch.
-
- To be precise, however, the fragment fixup logic is meant to fixup only the
- least-significant 4-bits (i.e., only the FRE type needs to be updated
- according to the function size).
-
- This patch makes the gas implementation a bit more resilient: In the
- future, when the format does evolve to make use of the currently unused
- 3-bits in various ways, the values in those 3-bits can be propagated
- unchanged while the fragment fixup continues to update the lowermost
- 4-bits to indicate the selected FRE type.
-

-
- * gas/gen-sframe.c (create_func_info_exp): New definition.
- (output_sframe_funcdesc): Call create_func_info_exp.

- [aarch64] Add TPIDR2 register support for Linux
- With the AArch64 Scalable Matrix Extension we have a new TPIDR2 register, and
- it will be added to the existing NT_ARM_TLS register set. Kernel patches are
- being reviewed here:
-
- https://lore.kernel.org/linux-arm-kernel/20220818170111.351889-1-broonie@kernel.org/
-
- From GDB's perspective, we handle it in a similar way to the existing TPIDR
- register. But we need to consider cases of systems that only have TPIDR and
- systems that have both TPIDR and TPIDR2.
-
- With that in mind, the following patch adds the required code to support
- TPIDR2 and turns the org.gnu.gdb.aarch64.tls feature into a
- dynamically-generated target description as opposed to a static target
- description containing only TPIDR.
-
- That means we can remove the gdb/features/aarch64-tls.xml file and replace the
- existing gdb/features/aarch64-tls.c auto-generated file with a new file that
- dynamically generates the target description containing either TPIDR alone or
- TPIDR and TPIDR2.
-
- In the future, when *BSD's start to support this register, they can just
- enable it as is being done for the AArch64 Linux target.
-
- The core file read/write code has been updated to support TPIDR2 as well.
-
- On GDBserver's side, there is a small change to the find_regno function to
- expose a non-throwing version of it.
-
- It always seemed strange to me how find_regno causes the whole operation to
- abort if it doesn't find a particular register name. The patch moves code
- from find_regno into find_regno_no_throw and makes find_regno call
- find_regno_no_throw instead.
-
- This allows us to do register name lookups to find a particular register
- number without risking erroring out if nothing is found.
-
- The patch also adjusts the feature detection code for aarch64-fbsd, since
- the infrastructure is shared amongst all aarch64 targets. I haven't added
- code to support TPIDR2 in aarch64-fbsd though, as I'm not sure when/if

- PR28306, segfault in _bfd_mips_elf_reloc_unshuffle
- Access to section data during relocation processing should be bounds
- checked, as it is in bfd_perform_relocation. bfd_perform_relocation
- does these checks after any special_function is called. So a reloc
- special_function needs to do its own bounds checking before accessing
- section data. This patch adds many such checks to the mips backend.
-
- Checking mips relocs is not without some difficulty. See the comment
- in _bfd_mips_reloc_offset_in_range. In a multitple reloc sequence
- applied to the same location, relocs that may appear somewhere other
- than the last one of the sequence need to be treated specially since
- they apply to the addend for the next relocation rather than the
- section contents. If the addend is in the section then it needs to be
- checked but not when the addend is in the reloc. check_inplace
- handles this situation. _bfd_mips_reloc_offset_in_range with
- check_shuffle handles the case where contents are shuffled before
- applying the relocation.

- gdb: skip objfiles with no BFD in DWARF unwinder
- While playing with JIT reader I experienced GDB to crash on null-pointer
- dereference when stepping through non-jitted code.
-
- The problem was that dwarf2_frame_find_fde () assumed that all objfiles
- have BFD but that's not always true. To address this problem, this
- commit skips such objfiles.
-
- To test the fix we put breakpoint in jit_function_add (). The JIT reader
- does not know how unwind this function so unwinding eventually falls
- back to DWARF unwinder which in turn iterates over objfiles. Since the
- the code is jitted, it is guaranteed it would eventually process JIT
- objfile.

- next^M
- 56 resumes++;^M
- (gdb) FAIL: gdb.base/longjmp.exp: next over longjmp(1)
- ...
-
- At first glance, the failure mode doesn't look too bad: we stop
- a few insns later than the passing scenario.
-
- For contrast, if we do the same on powerpc64le, the failure mode is:
- ...
- (gdb) PASS: gdb.base/longjmp.exp: next to longjmp (1)
- next^M
- ^M
- Breakpoint 3, main () at longjmp.c:59^M
- 59 i = 1; /* miss_step_1 */^M
- (gdb) FAIL: gdb.base/longjmp.exp: next over longjmp(1)
- ...
- Here we only stop because of running into the safety net breakpoint at
- miss_step_1.
-
- So, how does this happen on x86_64? Let's look at the code:
- ...
- 4005c7: e8 94 fe ff ff call 400460 <_setjmp@plt>
- 4005cc: 85 c0 test %eax,%eax
- 4005ce: 75 1e jne 4005ee <main+0x3b>
- 4005d0: 8b 05 8e 0a 20 00 mov 0x200a8e(%rip),%eax # 601064 <longjmps>
- 4005d6: 83 c0 01 add $0x1,%eax
- 4005d9: 89 05 85 0a 20 00 mov %eax,0x200a85(%rip) # 601064 <longjmps>
- 4005df: be 01 00 00 00 mov $0x1,%esi
- 4005e4: bf 80 10 60 00 mov $0x601080,%edi
- 4005e9: e8 82 fe ff ff call 400470 <longjmp@plt>
- 4005ee: 8b 05 74 0a 20 00 mov 0x200a74(%rip),%eax # 601068 <resumes>
- ...
- The next over the longjmp call at 4005e9 is supposed to stop at the longjmp
- target at 4005cc, but instead we stop at 4005ee, where we have the step-resume
- breakpoint inserted by the next. In other words, we accidentally "return"
- from the longjmp call to the insn immediately after it (even though
- a longjmp is a noreturn function).
-
- Try to avoid this accident and make the failure mode on x86_64 the same as on
- powerpc64le, by switching the then and else branch.
-
- Tested on x86_64-linux.

- gdb/testsuite: remove perror calls when failing to run
- I noticed that when running these two tests in sequence:
-
- Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.ada/arrayptr.exp ...
- ERROR: GDB process no longer exists
- ERROR: Couldn't run foo-all
- Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.ada/assign_1.exp ...
-
- The results in gdb.sum are:
-
- Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.ada/arrayptr.exp ...
- PASS: gdb.ada/arrayptr.exp: scenario=all: compilation foo.adb
- ERROR: GDB process no longer exists
- UNRESOLVED: gdb.ada/arrayptr.exp: scenario=all: gdb_breakpoint: set breakpoint at foo.adb:40 (eof)
- ERROR: Couldn't run foo-all
- Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.ada/assign_1.exp ...
- UNRESOLVED: gdb.ada/assign_1.exp: changing the language to ada
- PASS: gdb.ada/assign_1.exp: set convenience variable $xxx to 1
-
- The UNRESOLVED for arrayptr.exp is fine, as GDB crashes in that test,
- while trying to run to main. However, the UNRESOLVED in assign_1.exp
- doesn't make sense, GDB behaves as expected in that test:
-
- (gdb) set lang ada^M
- (gdb) UNRESOLVED: gdb.ada/assign_1.exp: changing the language to ada
- print $xxx := 1^M
- $1 = 1^M
- (gdb) PASS: gdb.ada/assign_1.exp: set convenience variable $xxx to 1
-
- The problem is that arrayptr.exp calls perror when failing to run to
- main, then returns. perror makes it so that the next test (as in
- pass/fail) will be recorded as UNRESOLVED. However, here, the next test
- (as in pass/fail) is in the next test (as in .exp). Hence the spurious
- UNRESOLVED in assign_1.exp.
-
- These perror when failing to run to X are not really useful, especially
- since runto records a FAIL on error, by default. Remove all the
- perrors on runto failure I could find.
-
- When there wasn't one already, add a return statement when failing to
- run, to avoid running the test of the test unnecessarily.
-
- I thought of adding a check ran between test (in gdb_finish
- probably) where we would emit a warning if errcnt > 0, meaning a test
- quit and left a perror "active". However, reading that variable would
- poke into the DejaGNU internals, not sure it's a good idea.

- libopcodes/mips: add support for disassembler styling
- This commit adds disassembler styling support for MIPS. After this
- commit objdump and GDB will style disassembler output.
-
- This is a pretty straight forward change, we switch to use the
- disassemble_info::fprintf_styled_func callback, and pass an
- appropriate style through as needed. No additional tricks were
- needed (compared to say i386, or ARM).
-
- Tested by running all of the objdump commands used by the gas
- testsuite and manually inspecting the styled output, everything looks
- reasonable, though I'm not a MIPS expert, so it is possible that I've
- missed some corner cases. Worst case though is that something will be
- styled incorrectly, the actual content should be unchanged.

- PowerPC, fix gdb.reverse/finish-reverse-bkpt.exp and gdb.reverse/next-reverse-bkpt-over-sr.exp
- The tests set a break point with the command break *func. This sets a
- breakpoint on the first instruction of the function. PowerPC uses
- Global Entry Points (GEP) and Local Entry Points (LEP). The first
- instruction in the function is the GEP. The GEP sets up register
- r2 before reaching the LEP. When the function is called with func() the
- function is entered via the LEP and the test fails because GDB does not
- see the breakpoint on the GEP. However, if the function is called via a
- function pointer, execution begins at the GEP as the test expects.
-
- Currently finish-reverse-bkpt.exp uses source file finish-reverse.c and
- next-reverse-bpkt-over-sr.exp uses source file step-reverse.c A new
- source file was created for tests finish-reverse-bkpt.exp and
- next-reverse-bkpt-over-sr.exp. The new files use the new function
- pointer method to call the functions so the tests will work correctly on
- both PowerPC with a GEP and LEP as well as on other systems. The GEP is
- the same as the LEP on non PowerPC systems.
-
- The expect files were changed to use the new source files and to set the
- initial break point for the rest of the test on the function pointer call
- for the function.
-
- This patch fixes two PowerPC test failures in each of the tests
- gdb.reverse/finish-reverse-bkpt.exp and
- gdb.reverse/next-reverse-bkpt-over-sr.exp.
-
- Patch tested on PowerPC and Intel X86-64 with no regressions.

- Add name canonicalization for C
- PR symtab/29105 shows a number of situations where symbol lookup can
- result in the expansion of too many CUs.
-
- What happens is that lookup_signed_typename will try to look up a type
- like "signed int". In cooked_index_functions::expand_symtabs_matching,
- when looping over languages, the C++ case will canonicalize this type
- name to be "int" instead. Then this method will proceed to expand
- every CU that has an entry for "int" -- i.e., nearly all of them. A
- crucial component of this is that the caller, objfile::lookup_symbol,
- does not do this canonicalization, so when it tries to find the symbol
- for "signed int", it fails -- causing the loop to continue.
-
- This patch fixes the problem by introducing name canonicalization for
- C. The idea here is that, by making C and C++ agree on the canonical
- name when a symbol name can have multiple spellings, we avoid the bad
- behavior in objfile::lookup_symbol (and any other such code -- I don't
- know if there is any).
-
- Unlike C++, C only has a few situations where canonicalization is
- needed. And, in particular, due to the lack of overloading (thus
- avoiding any issues in linespec) and due to the way c-exp.y works, I
- think that no canonicalization is needed during symbol lookup -- only
- during symtab construction. This explains why lookup_name_info is not
- touched.
-
- The stabs reader is modified on a "best effort" basis.
-
- The DWARF reader needed one small tweak in dwarf2_name to avoid a
- regression in dw2-unusual-field-names.exp. I think this is adequately
- explained by the comment, but basically this is a scenario that should
- not occur in real code, only the gdb test suite.
-
- lookup_signed_typename is simplified. It used to search for two
- different type names, but now gdb can search just for the canonical
- form.
-
- gdb.dwarf2/enum-type.exp needed a small tweak, because the
- canonicalizer turns "unsigned integer" into "unsigned int integer".
- It seems better here to use the correct C type name.

- gdb/dwarf: add some QUIT macros
- While testing the fix for PR 29105, I noticed I couldn't ctrl-C my way
- out of GDB expanding many symtabs. GDB was busy in a loop in
- cooked_index_functions::expand_symtabs_matching. Add a QUIT there. I
- also happened to see a spot in
- cooked_index_functions::expand_matching_symbols where a QUIT would be
- useful too, since we iterate over a potentially big number of index
- entries and expand CUs in the loop. Add one there too.

- gdb: remove prune_threads in thread_db_target::update_thread_list
- Pedro mentioned that this prune_threads call in
- thread_db_target::update_thread_list was not needed, and it was probably
- an oversight to leave it there in the work following commit e8032dde10b
- ("Push pruning old threads down to the target"). That commit changed
- the "find new threads" target operation to "update thread list", making
- the target responsible of adding new threads and removing exited
- threads, rather than just adding new threads. Commit e8032dde10b moved
- the prune_threads calls previously done in common code into each
- target's update_thread_list method, in order to keep the existing
- behavior, which is why this prune_threads call ended up there.
-
- In the mean time, the linux-nat target was taught to update_thread_list,
- and thread_db_target::update_thread_list defers to that for any live
- inferior, so the prune_threads call is not needed there. Otherwise, the
- thread_db_target::update_thread_list implementation based on
- td_ta_thr_iter_p only knows how to add new threads, not how to delete
- exited threads, but that is only used for non-live inferiors, where
- threads can't exit anyway. So the prune_threads call is not needed for
- that case either.

- Avoid timeouts in gdb.compile
- PR compile/29541 points out that some of the C++ tests in gdb.compile
- will time out when the glibc debuginfo is installed. This was
- interfering with my hacking on gdb by making test runs extremely long,
- so I looked into it.
-
- Internally the bug seems to be that gdb tries to convert multiple
- symbols named "var" via the compiler interface; one such symbol (I
- didn't track it down too far) causes the C++ compiler plugin to crash.
-
- Unfortunately, the crash is reported as a timeout, as the gdb side of
- the plugin simply hangs. This seems like a bug in the plugin RPC
- mechanism and, worse, apparently when I wrote this stuff I didn't
- really consider error reporting very much at all, so gdb can't really
- detect failures in the first place.
-
- Anyway... this patch works around the timeout by compiling a simple
- test that should provoke this bug, and then using "untested" if it
- notices a GCC crash.

- x86: rework of match_template()'s suffix checking
- (Ab)using i386_opcode_modifier for this has been overkill, as the logic
- doesn't really require the full structure. With the removal of
- LONG_DOUBLE_MNEM_SUFFIX and No_ldSuf there's no good reason at all
- anymore to pull out such a loop invariant: We're dealing a check of a
- bit in the loop for a simple comparison. Do the original compares inside
- the loop, thus also making it easier to understand what is actually
- being checked.

- anymore.
-
- x86/Intel: drop LONG_DOUBLE_MNEM_SUFFIX

- properly misnamed. Drop its use altogether, replacing it by a separate
- boolean instead.
-
- x86/Intel: restrict use of LONG_DOUBLE_MNEM_SUFFIX
- As a comment near the top of match_template() already says: We really
- only need this pseudo-suffix for far branch handling. Stop "deriving" it
- for floating point insns. (Don't bother renaming the now properly
- misnamed LONG_DOUBLE_MNEM_SUFFIX, to e.g. FAR_BRANCH_SUFFIX - it's going
- to disappear anyway.)

- section-select: Fix exclude-file-3
- this testcase wasn't correctly testing everything, it passed, even
- though sections from an excluded file were included. Fixing this
- reveals a problem in the new section selector. This fixes that as
- well.
-
- section-select: Remove unused code
- walk_wild_file, hence walk_wild_section and walk_wild_section_handler
- aren't called with the prefix tree. Hence initialization of the latter
- and all potential special cases for it aren't used anymore. That also

-
- section-select: Implement a prefix-tree
- Now that we have a list of potentially matching sections per wild
- statement we can actually pre-fill that one by going once over all input
- sections and match their names against a prefix-tree that points to the
- potentially matching wild statements.
-
- So instead of looking at all sections names for each glob for each wild
- statement we now look at the sections only once and then only check
- against those globs that have a possibility of a match at all (usually
- only one or two).
-
- This pushes the whole section selection off the profiles.

-2022-11-30 Michael Matz <matz@suse.de>
-
- section-select: Completely rebuild matches
- The check_relocs callback (and others) might have created new
- section behind our back and some of them (e.g. on powerpc the
- "linker stubs" .got) need to come in front of all others, despite
- being created late (a symptom would be "TOC opt*" failing on powerpc).
-
- This resets all section matches before updating for newly created
- sections (i.e. completely rebuilds the matches).
-
-2022-11-30 Michael Matz <matz@suse.de>
-
- section-select: Lazily resolve section matches
- and remember the results. Before this the order of section matching
- is basically:
-
- foreach script-wild-stmt S
- foreach pattern P of S
- foreach inputfile I
- foreach section S of I
- match S against P
- if match: do action for S
-
- And this process is done three or four times: for each top-level call to
- walk_wild() or wild(), that is: check_input_sections, lang_gc_sections,
- lang_find_relro_sections and of course map_input_to_output_sections.
-
- So we iterate over all sections of all files many many times (for each
- glob). Reality is a bit more complicated (some special glob types don't
- need the full iteration over all sections, only over all files), but
- that's the gist of it.
-
- For future work this shuffles the whole ordering a bit by lazily doing
- the matching process and memoizing results, trading a little memory for
- a 75% speedup of the overall section selection process.
-
- This lazy resolution introduces a problem with sections added late
- that's corrected in the next patch.

- x86: clean up after removal of support for gcc <= 2.8.1
- At the very least a comment in process_operands() is stale. Beyond that

- 1) It is possible that FADDP and FMULP were mistakenly not marked as
- being in need of dealing with the compiler anomaly, and hence the
- respective templates weren't removed at the time when they should
- have been.
- 2) It is also possible that there are indeed uses known beyond compiler
- generated output for these two commutative opcodes, and hence the
- templates need to stay.
- To be on the safe side assume 2: Update the comment and fold the
- templates into their "normal" ones (utilizing D), adjusting consuming

- For FMULP also add a comment paralleling a similar one FADDP has.

- Also move the respective conditional out of the code path taken by all
- "reverse match" insns (it probably should have been this way already
- before, to avoid the one conditional in the common case).
-
- With this the templates which had FloatR dropped no longer differ from
- their AT&T syntax + mnemonic counterparts - the only difference is now
- which of the two would be recognized. For this, however, we don't need
- two templates - we can simply arrange the condition for setting

-
- When trying to evaluate DW_OP_GNU_entry_value, it looks for a call site
- matching the pc, but doesn't find it:
- ...
- $ gdb -q -batch outputs/gdb.base/vla-optimized-out/vla-optimized-out-o1 \

- 34 }
- DW_OP_entry_value resolving cannot find DW_TAG_call_site 0x100006b0 in main
- $1 = <optimized out>
- ....
-
- The call site lookup fails because the call site label .LVL4:
- ...
- bl f1 # 11 *call_value_nonlocal_aixdi [length = 8]
- nop
- .LVL4:
- ...
- is not placed directly after the bl insn. This is gcc PR target/107909.
-
- However, after manually fixing the .s file we have instead:
- ...
- Cannot find matching parameter at DW_TAG_call_site 0x10000690 at main
- $1 = <optimized out>
- ...
- due to the fact that the call site has no call site parameters.
-
- The call site does have a reference to the corresponding function f1, with
- parameter i, for which we find location list entries:
- ...
- 0037 1000067c 10000680 (DW_OP_reg3 (r3))
- 004a 10000680 10000690 (DW_OP_GNU_entry_value: (DW_OP_reg3 (r3));
- DW_OP_stack_value)
- ...
- and we could use the fact that the current pc is in the 1000067c-10000680
- range, and that that the range starts at the start of the function, to deduce
- that DW_OP_GNU_entry_value: (DW_OP_reg3 (r3)) == DW_OP_reg3 (r3).
- But that's a non-trivial enhancement, filed as enhancement PR symtab/29836.
-
- Fix this by allowing <optimized out> for target powerpc and the gcc compiler.

-
- https://inbox.sourceware.org/gdb-patches/20221120173024.3647464-1-philippe.waroquiers@skynet.be/
-
- ... the testsuite only outputs PASSes, and an ERROR, resulting from an
- uncaught exception. This is a bit sneaky, because ERRORs are not
- reported in the test summary. In certain circumstances, it can be easy
- to miss.
-
- Normally, gdb_test_multiple outputs an UNRESOLVED when GDB crashes. But
- this is only if it manages to send the command, and it's that command
- that crashes GDB. Here, the ERROR is due to the fact that GDB had
- already crashed by the time we entered gdb_test_multiple and tried to
- send a command. GDB was crashed by the previous "file" command, sent by
- gdb_unload. Because gdb_unload uses bare expect, it didn't record a
- test failure when crashing GDB (this will be addressed separately).
-
- In this patch, I propose to make gdb_test_multiple call unresolved
- directly and return -1 send_gdb fails. This way, if GDB is already
- crashed by the time we enter gdb_test_multiple, it will leave a trace in
- the test results in the form of an UNRESOLVED. It will also spare us
- the not-so-useful-in-my-opinion TCL backtrace.
-
- Before, it looks like:
-
- ERROR: Couldn't send python print(objfile.filename) to GDB.
- ERROR: : spawn id exp9 not open
- while executing
- "expect {
- -i exp9 -timeout 10
- -re ".*A problem internal to GDB has been detected" {
- fail "$message (GDB internal error)"
- gdb_internal_error..."
- ("uplevel" body line 1)
- invoked from within
- "uplevel $body" NONE : spawn id exp9 not open
-
- And after:
-
- Couldn't send python print(objfile.filename) to GDB.
- UNRESOLVED: gdb.python/py-objfile.exp: objfile.filename after objfile is unloaded

- gdb: mark disassembler function callback types as noexcept
- In disasm.h we define a set of types that are used by the various
- disassembler classes to hold callback functions before passing the
- callbacks into libopcodes.
-
- Because libopcodes is C code, and on some (many?) targets, C code is
- compiled without exception support, it is important that GDB not try
- to throw an exception over libopcode code.
-
- In the previous commit all the existing callbacks were marked as
- noexcept, however, this doesn't protect us from a future change to GDB
- either adding a new callback that is not noexcept, or removing the
- noexcept keyword from an existing callback.
-
- In this commit I mark all the callback types as noexcept. This means
- that GDB's disassembler classes will no longer compile if we try to
- pass a callback that is not marked as noexcept.
-
- At least, that's the idea. Unfortunately, it's not that easy.
-
- Before C++17, the noexcept keyword on a function typedef would be
- ignored, thus:
-
- using func_type = void (*) (void) noexcept;
-
- void
- a_func ()
- {
- throw 123;
- }
-
- void
- some_func (func_type f)
- {
- f ();
- }
-
- int
- main ()
- {
- some_func (a_func);
- return 0;
- }
-
- Will compile just fine for C++11 and C++14 with GCC. Clang on the
- other hand complains that 'noexcept' should not appear on function
- types, but then does appear to correctly complain that passing a_func
- is a mismatch in the set of exceptions that could be thrown.
-
- Switching to C++17 and both GCC and Clang correctly point out that
- passing a_func is an invalid conversion relating to the noexcept
- keyword. Changing a_func to:
-
- void
- a_func () noexcept
- { /* Nothing. */ }
-
- And for C++17 both GCC and Clang compile this just fine.
-
- My conclusion then is that adding the noexcept keyword to the function
- types is pointless while GDB is not compiled as C++17, and silencing
- the warnings would require us to jump through a bunch of hoops.
-
- And so, in this commit, I define a macro LIBOPCODE_CALLBACK_NOEXCEPT,
- this macro expands to noexcept when compiling for C++17, but otherwise
- expands to nothing. I then add this macro to the function types.
-
- I've compiled GDB as the default C++11 and also forced the compile to
- C++17. When compiling as C++17 I spotted a few additional places
- where callbacks needed to be marked noexcept (these fixes were merged
- into the previous commit, but this confirmed to be that the macro is
- working as expected).

- gdb/disasm: mark functions passed to the disassembler noexcept
- While working on another patch, Simon pointed out that GDB could be
- improved by marking the functions passed to the disassembler as
- noexcept.
-
- https://sourceware.org/pipermail/gdb-patches/2022-October/193084.html
-
- The reason this is important is the on some hosts, libopcodes, being C
- code, will not be compiled with support for handling exceptions. As
- such, an attempt to throw an exception over libopcodes code will cause
- GDB to terminate.
-
- See bug gdb/29712 for an example of when this happened.
-
- In this commit all the functions that are passed to the disassembler,
- and which might be used as callbacks by libopcodes are marked
- noexcept.
-
- Ideally, I would have liked to change these typedefs:
-
- using read_memory_ftype = decltype (disassemble_info::read_memory_func);
- using memory_error_ftype = decltype (disassemble_info::memory_error_func);
- using print_address_ftype = decltype (disassemble_info::print_address_func);
- using fprintf_ftype = decltype (disassemble_info::fprintf_func);
- using fprintf_styled_ftype = decltype (disassemble_info::fprintf_styled_func);
-
- which are declared in disasm.h, as including the noexcept keyword.
- However, when I tried this, I ran into this warning/error:
-
- In file included from ../../src/gdb/disasm.c:25:
- ../../src/gdb/disasm.h: In constructor ‘gdb_printing_disassembler::gdb_printing_disassembler(gdbarch*, ui_file*, gdb_disassemble_info::read_memory_ftype, gdb_disassemble_info::memory_error_ftype, gdb_disassemble_info::print_address_ftype)’:
- ../../src/gdb/disasm.h:116:3: error: mangled name for ‘gdb_printing_disassembler::gdb_printing_disassembler(gdbarch*, ui_file*, gdb_disassemble_info::read_memory_ftype, gdb_disassemble_info::memory_error_ftype, gdb_disassemble_info::print_address_ftype)’ will change in C++17 because the exception specification is part of a function type [-Werror=noexcept-type]
- 116 | gdb_printing_disassembler (struct gdbarch *gdbarch,
- | ^~~~~~~~~~~~~~~~~~~~~~~~~
-
- So I've left that change out. This does mean that if somebody adds a
- new use of the disassembler classes in the future, and forgets to mark
- the callbacks as noexcept, this will compile fine. We'll just have to
- manually check for that during review.

- gdb/python: avoid throwing an exception over libopcodes code
- Bug gdb/29712 identifies a problem with the Python disassembler API.
- In some cases GDB will try to throw an exception through the
- libopcodes disassembler code, however, not all targets include
- exception unwind information when compiling C code, for targets that
- don't include this information GDB will terminate when trying to pass
- the exception through libopcodes.
-
- To explain what GDB is trying to do, consider the following trivial
- use of the Python disassembler API:
-
- class ExampleDisassembler(gdb.disassembler.Disassembler):
-
- class MyInfo(gdb.disassembler.DisassembleInfo):
- def __init__(self, info):
- super().__init__(info)
-
- def read_memory(self, length, offset):
- return super().read_memory(length, offset)
-
- def __init__(self):
- super().__init__("ExampleDisassembler")
-
- def __call__(self, info):
- info = self.MyInfo(info)
- return gdb.disassembler.builtin_disassemble(info)
-
- This disassembler doesn't add any value, it defers back to GDB to do
- all the actual work, but it serves to allow us to discuss the problem.
-
- The problem occurs when a Python exception is raised by the
- MyInfo.read_memory method. The MyInfo.read_memory method is called
- from the C++ function gdbpy_disassembler::read_memory_func. The C++
- stack at the point this function is called looks like this:
-
- #0 gdbpy_disassembler::read_memory_func (memaddr=4198805, buff=0x7fff9ab9d2a8 "\220ӹ\232\377\177", len=1, info=0x7fff9ab9d558) at ../../src/gdb/python/py-disasm.c:510

-
- So gdbpy_disassembler::read_memory_func is called from the libopcodes
- disassembler to read memory, this C++ function then calls into user
- supplied Python code to do the work.
-
- If the user supplied Python code raises an gdb.MemoryError exception
- indicating the memory read failed, this is fine. The C++ code
- converts this exception back into a return value that libopcodes can
- understand, and returns to libopcodes.
-
- However, if the user supplied Python code raises some other exception,
- what we want is for this exception to propagate through GDB and appear
- as if raised by the call to gdb.disassembler.builtin_disassemble. To
- achieve this, when gdbpy_disassembler::read_memory_func spots an
- unknown Python exception, we must pass the information about this
- exception from frame #0 to frame #8 in the above backtrace. Frame #8
- is the C++ implementation of gdb.disassembler.builtin_disassemble, and
- so it is this function that we want to re-raise the unknown Python
- exception, so the user can, if they want, catch the exception in their
- code.
-
- The previous mechanism by which the exception was passed was to pack
- the details of the Python exception into a C++ exception, then throw
- the exception from frame #0, and catch the exception in frame #8,
- unpack the details of the Python exception, and re-raise it.
-
- However, this relies on the exception passing through frames #1 to #7,
- some of which are in libopcodes, which is C code, and so, might not be
- compiled with exception support.
-
- This commit proposes an alternative solution that does not rely on
- throwing a C++ exception.
-
- When we spot an unhandled Python exception in frame #0, we will store
- the details of this exception within the gdbpy_disassembler object
- currently in use. Then we return to libopcodes a value indicating
- that the memory_read failed.
-
- libopcodes will now continue to disassemble as though that memory read
- failed (with one special case described below), then, when we
- eventually return to disasmpy_builtin_disassemble we check to see if
- there is an exception stored in the gdbpy_disassembler object. If
- there is then this exception can immediately be installed, and then we
- return back to Python, when the user will be able to catch the
- exception.
-
- There is one extra change in gdbpy_disassembler::read_memory_func.
- After the first call that results in an exception being stored on the
- gdbpy_disassembler object, any future calls to the ::read_memory_func
- function will immediately return as if the read failed. This avoids
- any additional calls into user supplied Python code.
-
- My thinking here is that should the first call fail with some unknown
- error, GDB should not keep trying with any additional calls. This
- maintains the illusion that the exception raised from
- MyInfo.read_memory is immediately raised by
- gdb.disassembler.builtin_disassemble. I have no tests for this change
- though - to trigger this issue would rely on a libopcodes disassembler
- that will try to read further memory even after the first failed
- read. I'm not aware of any such disassembler that currently does
- this, but that doesn't mean such a disassembler couldn't exist in the
- future.
-
- With this change in place the gdb.python/py-disasm.exp test should now
- pass on AArch64.

- Remove reset_ecs and execution_control_state::reset
- I noticed that execution_control_state has a 'reset' method, and
- there's also a 'reset_ecs' function that calls it. This patch cleans
- this area up a little by adding a parameter to the constructor and (a
- change Simon suggested) removing the reset method. Some extraneous
- variables are also removed, like:
-
- - struct execution_control_state ecss;
- - struct execution_control_state *ecs = &ecss;
-
- Here 'ecs' is never changed, so this patch removes it entirely in
- favor of just using the object everywhere.

- gdb: relax requirement for the map_failed stap probe to be present
- From glibc 2.35 and later, the "map_failed" stap probe is no longer
- included in glibc. The removal of the probe looks like an accident,
- but it was caused by a glibc commit which meant that the "map_failed"
- probe could no longer be reached; the compiler then helpfully
- optimised out the probe.
-
- In GDB, in solib-svr4.c, we have a list of probes that we look for
- related to the shared library loading detection. If any of these
- probes are missing then GDB will fall back to the non-probe based
- mechanism for detecting shared library loading. The "map_failed"
- probe is include in the list of required probes.
-
- This means that on glibc 2.35 (or later) systems, GDB is going to
- always fall back to the non-probes based mechanism for detecting
- shared library loading.
-
- I raised a glibc bug to discuss this issue:
-
- https://sourceware.org/bugzilla/show_bug.cgi?id=29818
-
- But, whatever the ultimate decision from the glibc team, given there
- are version of glibc in the wild without the "map_failed" probe, we
- probably should update GDB to handle this situation.
-
- The "map_failed" probe is already a little strange, very early
- versions of glibc didn't include this probe, so, in some cases, if
- this probe is missing GDB is happy to ignore it. This is fine, the
- action associated with this probe inside GDB is DO_NOTHING, this means
- the probe isn't actually required in order for GDB to correctly detect
- the loading of shared libraries.
-
- In this commit I propose changing the rules so that any probe whose
- action is DO_NOTHING, is optional.
-
- There is one possible downside to this change, and that concerns 'set
- stop-on-solib-events on'. If a probe is removed from glibc, but the
- old style breakpoint based mechanism is still in place within glibc
- for that same event, then GDB will stop when using the old style
- non-probe based mechanism, but not when using the probes based
- mechanism.
-
- For the map_failed case this is not a problem, both the map_failed
- probe, and the call to the old style breakpoint location were
- optimised out, and so neither event (probes based, or breakpoint
- based) will trigger. This would only become an issue if glibc removed
- a probe, but left the breakpoint in place (this would almost certainly
- be a bug in glibc).
-
- For now, I'm proposing that we just don't worry about this. Because
- some probes have actions that are not DO_NOTHING, then we know the
- user will always seem _some_ stops when a shared library is
- loaded/unloaded, and (I'm guessing), in most cases, that's all they
- care about. I figure when someone complains then we can figure out
- what the right solution is then.
-
- With this commit in place, then, when using a glibc 2.35 or later
- system, GDB will once again use the stap probes for shared library
- detection.

- Warning: In multi-threaded programs, software watchpoints have only limited

- confident that no other thread can become current), then you can use software
- watchpoints as usual. However, GDB may not notice when a non-current thread’s

- Only use wild_sort_fast
- there's no reason why the tree-based variant can't always be used
- when sorting is required, it merely needs to also support filename
- sorting and have a fast path for insertion at end (aka rightmost tree
- leaf).
-
- The filename sorting isn't tested anywhere and the only scripttempl
- that uses it is avr (for 'SORT(*)(.ctors)'), and I believe even there it
- was a mistake. Either way, this adds a testcase for filename sorting as
- well.
-
- Then the non-BST based sorting can be simplified to only support

- gdb/testsuite: fail if gdb_start_cmd fails
- I broke gdb.ada/start.exp, and did not notice it, because it outputs an
- UNTESTED if gdb_start_cmd fails. I don't really see when start would
- fail and it's not a problem that should be looked at. Change all spots
- that call untested after a gdb_start_cmd failure, use fail instead.
-
- Doing so caused some failures with the native-gdbserver board. Some
- tests that use "start" were relying on the fact that start would fail
- with that board to just return with "untested". Change them to add an
- early return if use_gdb_stub returns true.
-
- Some gdb.pascal tests also failed with native-gdbserver, because they
- did use gdb_start_cmd to start the inferior, for no good reason.
- Convert them to use runto_main instead, which does the right thing if
- the target is a stub.
-
- A further refactoring could be to make gdb_start_cmd match the expected
- breakpoint hit and the prompt, which it doesn't do currently (it leaves
- that to the callers, but not all of them do).

- When running the kill command, commit_resumed_state for the
- process_stratum_target (linux-nat, here) is true. After the kill, when
- there are no more threads, commit_resumed_state is still true, as
- nothing touches this flag during the kill operation. During the
- subsequent run command, run_command_1 does:
-
- scoped_disable_commit_resumed disable_commit_resumed ("running");
-
- We would think that this would clear the commit_resumed_state flag of
- our native target, but that's not the case, because
- scoped_disable_commit_resumed iterates on non-exited inferiors in order
- to find active process targets. And after the kill, the inferior is
- exited, and the native target was unpushed from it anyway. So
- scoped_disable_commit_resumed doesn't touch the commit_resumed_state
- flag of the native target, it stays true. When reaching target_wait, in
- startup_inferior (to consume the initial expect stop events while the
- inferior is starting up and working its way through the shell),
- commit_resumed_state is true, breaking the contract saying that
- commit_resumed_state is always false when calling the targets' wait
- method.
-
- (note: to be correct, I think that startup_inferior should toggle
- commit_resumed between the target_wait and target_resume calls, but I'll
- ignore that for now)
-
- I can see multiple ways to fix this. In the end, we need
- commit_resumed_state to be cleared by the time we get to that
- target_wait. It could be done at the end of the kill command, or at the
- beginning of the run command.
-
- To keep things in a coherent state, I'd like to make it so that after
- the kill command, when the target is left with no threads, its
- commit_resumed_state flag is left to false. This way, we can keep
- working with the assumption that a target with no threads (and therefore
- no running threads) has commit_resumed_state == false.
-
- Do this by adding a scoped_disable_commit_resumed in target_kill. It
- clears the target's commit_resumed_state on entry, and leaves it false
- if the target does not have any resumed thread on exit. That means,
- even if the target has another inferior with stopped threads,
- commit_resumed_state will be left to false, which makes sense.
-
- Add a test that tries to cover various combinations of actions done
- while an inferior is running (and therefore while commit_resumed_state
- is true on the process target).

- The reason is a wrong current process when find_one_thread is called.
- The current process is the 2nd one, which was just attached. It does
- not yet have thread_db data (proc->priv->thread_db is nullptr). As we
- iterate on all threads of all process to fulfull the qxfer:threads:read
- request, we get to a thread of process 1 for which we haven't read
- thread_db information yet (lwp_info::thread_known is false), so we get
- into find_one_thread. find_one_thread uses
- `current_process ()->priv->thread_db`, assuming the current process
- matches the ptid passed as a parameter, which is wrong. A segfault
- happens when trying to dereference that thread_db pointer.
-
- Fix this by making find_one_thread not assume what the current process /
- current thread is. If it needs to call into libthread_db, which we know
- will try to read memory from the current process, then temporarily set
- the current process.
-
- In the case where the thread is already know and we return early, we
- don't need to switch process.
-

-
- So we step from line 29 to line 28, and back to line 29, which is behaviour

- gdb: fix assert when quitting GDB while a thread is stepping
- This commit addresses one of the issues identified in PR gdb/28275.
-
- Bug gdb/28275 identifies a number of situations in which this assert:
-
- Assertion `!proc_target->commit_resumed_state' failed.
-
- could be triggered. There's actually a number of similar places where
- this assert is found in GDB, the two of interest in gdb/28275 are in
- target_wait and target_stop.
-
- In one of the comments:
-
- https://sourceware.org/bugzilla/show_bug.cgi?id=28275#c1
-
- steps to trigger the assertion within target_stop were identified when
- using a modified version of the gdb.threads/detach-step-over.exp test
- script.
-
- In the gdb.threads/detach-step-over.exp test, we attach to a
- multi-threaded inferior, and continue the inferior in asynchronous
- (background) mode. Each thread is continuously hitting a conditional
- breakpoint where the condition is always false. While the inferior is
- running we detach. The goal is that we detach while GDB is performing a
- step-over for the conditional breakpoint in at least one thread.
-
- While detaching, if a step-over is in progress, then GDB has to
- complete the step over before we can detach. This involves calling
- target_stop and target_wait (see prepare_for_detach).
-
- As far as gdb/28275 is concerned, the interesting part here, is the
- the process_stratum_target::commit_resumed_state variable must be
- false when target_stop and target_wait are called.
-
- This is currently ensured because, in detach_command (infrun.c), we
- create an instance of scoped_disable_commit_resumed, this ensures that
- when target_detach is called, ::commit_resumed_state will be false.
-
- The modification to the test that I propose here, and which exposed
- the bug, is that, instead of using "detach" to detach from the
- inferior, we instead use "quit". Quitting GDB after attaching to an
- inferior will cause GDB to first detach, and then exit.
-
- When we quit GDB we end up calling target_detach via a different code
- path, the stack looks like:
-
- #0 target_detach
- #1 kill_or_detach
- #2 quit_force
- #3 quit_command
-
- Along this path there is no scoped_disable_commit_resumed created.
- ::commit_resumed_state can be true when we reach prepare_for_detach,
- which calls target_wait and target_stop, so the assertion will trigger.
-
- In this commit, I propose fixing this by adding the creation of a
- scoped_disable_commit_resumed into target_detach. This will ensure
- that ::commit_resumed_state is false when calling prepare_for_detach
- from within target_detach.
-
- I did consider placing the scoped_disable_commit_resumed in
- prepare_for_detach, however, placing it in target_detach ensures that
- the target's commit_resumed_state flag is left to false if the detached
- inferior was the last one for that target. It's the same rationale as
- for patch "gdb: disable commit resumed in target_kill" that comes later
- in this series, but for detach instead of kill.
-
- detach_command still includes a scoped_disable_commit_resumed too, but I
- think it is still relevant to cover the resumption at the end of the
- function.

- RISC-V: Better support for long instructions (assembler)
- Commit bb996692bd96 ("RISC-V/gas: allow generating up to 176-bit
- instructions with .insn") tried to start supporting long instructions but
- it was insufficient.
-
- 1. It heavily depended on the bignum internals (radix of 2^16),
- 2. It generates "value conflicts with instruction length" even if a big
- number instruction encoding does not exceed its expected length and
- 3. Because long opcode was handled separately (from struct riscv_cl_insn),
- some information like DWARF line number correspondence was missing.
-
- To resolve these problems, this commit:
-
- 1. Handles bignum (and its encodings) precisely and
- 2. Incorporates long opcode handling into regular instruction handling.
-
- This commit will be tested on the separate commit.

- RISC-V: Better support for long instructions (disassembler)
- Commit bb996692bd96 ("RISC-V/gas: allow generating up to 176-bit
- instructions with .insn") tried to start supporting long instructions but
- it was insufficient.
-
- On the disassembler, correct ".byte" output was limited to the first 64-bits
- of an instruction. After that, zeroes are incorrectly printed.
-
- Note that, it only happens on ".byte" output (instruction part) and not on
- hexdump (data) part. For example, before this commit, hexdump and ".byte"
- produces different values:
-
- Assembly:
- .insn 22, 0xfedcba98765432100123456789abcdef55aa33cc607f
- objdump output example (before the fix):
- 10: 607f 33cc 55aa cdef .byte 0x7f, 0x60, 0xcc, 0x33, 0xaa, 0x55, 0xef, 0xcd, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00
- 18: 89ab 4567 0123 3210
- 20: 7654 ba98 fedc
-
- Note that, after 0xcd (after first 64-bits of the target instruction), all
- ".byte" values are incorrectly printed as zero while hexdump prints correct
- instruction bits.
-
- To resolve this, this commit adds "packet" argument to support dumping
- instructions longer than 64-bits (to print correct instruction bits on
- ".byte"). This commit will be tested on the separate commit.

- Fix leak in the dwarf reader
- Valgrind reports a leak in the dwarf reader (see details below).
- The function dw2_get_file_names_reader is interning in the per_objfile
- all the file names it finds, except the name of 'fnd file name and directory'.
- Instead, it was xstrdup-ing the name.
- Fix the leaks by also interning the name.
-
- This was validated running the tests natively, and under valgrind.
- Leaks have decreased as mentionned below.
- Valgrind detected no error such as double free or use after free.

- [gdb/server] Emit warning for SIGINT failure
- Consider the executable from test-case gdb.base/interrupt-daemon.exp.
-
- When starting it using gdbserver:
- ...
- $ ./build/gdbserver/gdbserver localhost:2345 \
- ./outputs/gdb.base/interrupt-daemon/interrupt-daemon
- ...
- and connecting to it using gdb:
- ...
- $ gdb -q -ex "target remote localhost:2345" \
- -ex "set follow-fork-mode child" \
- -ex "break daemon_main" -ex cont
- ...
- we are setup to do the same as in the test-case: interrupt a running inferior
- using ^C.
-
- So let's try:
- ...
- (gdb) continue
- Continuing.
- ^C
- ...
- After pressing ^C, nothing happens. This a known problem, filed as
- PR remote/18772.
-
- The problem is that in linux_process_target::request_interrupt, a kill is used
- to send a SIGINT, but it fails. And it fails silently.
-
- Make the failure verbose by adding a warning, such that the gdbserver output
- becomes more helpful:
- ...
- Process interrupt-daemon created; pid = 15068
- Listening on port 2345
- Remote debugging from host ::1, port 35148
- Detaching from process 15068
- Detaching from process 15085
- gdbserver: Sending SIGINT to process group of pid 15068 failed: \
- No such process
- ...
-
- Note that the failure can easily be reproduced using the test-case and target
- board native-gdbserver:
- ...
- (gdb) continue^M
- Continuing.^M
- PASS: gdb.base/interrupt-daemon.exp: fg: continue
- ^CFAIL: gdb.base/interrupt-daemon.exp: fg: ctrl-c stops process (timeout)
- ...
- as reported in PR server/23382.

- [gdb/testsuite] Don't generate core in gdb.base/bt-on-fatal-signal.exp
- When running test-case gdb.base/bt-on-fatal-signal.exp on powerpc64le-linux I
- noticed:
- ...
- FAIL: gdb.base/bt-on-fatal-signal.exp: SEGV: scan for backtrace (timeout)
- ...
-
- The timeout is 10 seconds, but generating the core file takes more than a
- minute, probably due to slow NFS.
-
- I managed to reproduce this behaviour independently of gdb, by compiling
- "int main (void) { __builtin_abort (); }" and running it, which took 1.5
- seconds for a core file 50 times smaller than the one for gdb.
-
- Fix this by preventing the core file from being generated, using a wrapper
- around gdb that does "ulimit -c 0".
-
- Tested on x86_64-linux.

- [gdb/symtab] Handle failure to open .gnu_debugaltlink file

- dwz has created it, with test-case
- gdb.threads/access-mem-running-thread-exit.exp and target board cc-with-dwz-m
- we run into:

- gdb/dwarf2/read.c:7284: internal-error: create_all_units: \
- Assertion `per_objfile->per_bfd->all_units.empty ()' failed.^M
- ...
-
- The problem is that create_units does not catch the error thrown by
- dwarf2_get_dwz_file.
-
- Fix this by catching the error and performing the necessary cleanup, getting
- the same result for the first and second file command.

- x86: widen applicability and use of CheckRegSize
- First of all make operand_type_register_match() apply to all sized
- operands, i.e. in Intel Syntax also to respective memory ones. This
- addresses gas wrongly accepting certain SIMD insns where register and
- memory operand sizes should match but don't. This apparently has
- affected all templates with one memory-only operand and one or more
- register ones, both permitting at least two sizes, due to CheckRegSize
- not taking effect.
-
- Then also add CheckRegSize to a couple of non-SIMD templates matching
- that same pattern of memory-only vs register operands. This replaces
- bogus (for Intel Syntax) diagnostics referring to a wrong suffix (when
- none was used at all) by "type mismatch" ones, just like already emitted
- for insns where the template allows a register operand alongside a
- memory one at any particular position.
-
- This also is a prereq to limiting (ideally eliminating in the long run)
- suffix "derivation" in Intel Syntax mode.
-
- While making the code adjustment also flip order of checks to do the
- cheaper one first in both cases.

-
- x86: add missing CheckRegSize
- To properly and predictably determine operand size encoding (operand
- size or REX.W prefixes), consistent operand sizes need to be specified.
- Add CheckRegSize where this was previously missing.
-
- x86: correct handling of LAR and LSL
- Both uniformly only ever take 16-bit memory operands while at the same
- time requiring matching (in size) register operands, which then also
- should disassemble that way. This in particular requires splitting each
- of the templates for the assembler and separating decode of the
- register and memory forms in the disassembler.

- Fix gdb.cp/gdb2495.exp on powerpc64le
- On powerpc64le-linux I ran into this FAIL:
- ...
- (gdb) p exceptions.throw_function()^M
- terminate called after throwing an instance of 'int'^M
- ^M
- Program received signal SIGABRT, Aborted.^M
- 0x00007ffff7979838 in raise () from /lib64/libc.so.6^M
- The program being debugged was signaled while in a function called from GDB.^M
- GDB remains in the frame where the signal was received.^M
- To change this behavior use "set unwindonsignal on".^M
- Evaluation of the expression containing the function^M
- (SimpleException::throw_function()) will be abandoned.^M
- When the function is done executing, GDB will silently stop.^M
- (gdb) FAIL: gdb.cp/gdb2495.exp: call a function that raises an exception \
- without a handler.
- ...
-
- The following happens:
- - we start an inferior call
- - an internal breakpoint is set on the global entry point of std::terminate
- - the inferior call uses the local entry point
- - the breakpoint is not triggered
- - we run into std::terminate
-
- We can fix this by simply adding the missing gdbarch_skip_entrypoint call in
- create_std_terminate_master_breakpoint, but we try to do this a bit more
- generic, by:
- - adding a variant of function create_internal_breakpoint which takes a
- minimal symbol instead of an address as argument
- - in the new function:
- - using both gdbarch_convert_from_func_ptr_addr and gdbarch_skip_entrypoint
- - documenting why we don't need to use gdbarch_addr_bits_remove
- - adding a note about possibly
- needing gdbarch_deprecated_function_start_offset.
- - using the new function in:
- - create_std_terminate_master_breakpoint
- - create_exception_master_breakpoint_hook, which currently uses only
- gdbarch_convert_from_func_ptr_addr.
-
- Note: we could use the new function in more locations in breakpoint.c, but
- as we're not aware of any related failures, we declare this out of scope for
- this patch.
-
- Tested on x86_64-linux, powerpc64le-linux.

- RISC-V: Make R_RISCV_SUB6 conforms to riscv ABI standard
- According to the riscv psabi, R_RISCV_SUB6 only allows 6 least significant
- bits are valid, but since binutils implementation, we usually get 8 bits
- field for it. That means, the high 2 bits could be other field and have
- different purpose. Therefore, we should filter the 8 bits to 6 bits before
- calculate, and then only encode the valid 6 bits back. By the way, we also
- need the out-of-range check for R_RISCV_SUB6, and the overflow checks for
- all R_RISCV_ADD/SUB/SET relocations, but we can add them in the future patches.
-
- Passing riscv-gnu-toolchain regressions.

-
- * elfnn-riscv.c (riscv_elf_relocate_section): Take the R_RISCV_SUB6
- lower 6 bits as the significant bit.

- regcache: Add collect/supply_regset variants that accept a register base.
- Some register sets described by an array of regcache_map_entry
- structures do not have fixed register numbers in their associated
- architecture but do describe a block of registers whose numbers are at
- fixed offsets relative to some base register value. An example of
- this are the TLS register sets for the ARM and AArch64 architectures.
-
- Currently OS-specific architectures create register maps and register
- sets dynamically using the register base number. However, this
- requires duplicating the code to create the register map and register
- set. To reduce duplication, add variants of the collect_regset and
- supply_regset regcache methods which accept a base register number.
- For valid register map entries (i.e. not REGCACHE_MAP_SKIP), add this
- base register number to the value from the map entry to determine the
- final register number.

- readelf: use fseeko64 or fseeko if possible
- Changes readelf to make use first of fseeko64 and then fseeko,
- depending on which of those is available. If neither is available,
- reverts to the previous behavior of using fseek.
-
- This is necessary when building readelf for LLP64 systems, where a
- long will only be 32 bits wide. If the elf file in question is >= 2 GiB,
- that is greater than the max long value and therefore fseek will fail
- indicating that the offset is negative. On such systems, making use of
- fseeko64 or fseeko will result in the ability so seek past the 2 GiB
- max long boundary.
-
- Note that large archive handling in readelf remains to be fixed.

- Show locno for 'multi location' breakpoint hit msg+conv var $_hit_bbnum $_hit_locno PR breakpoints/12464
- This implements the request given in PR breakpoints/12464.
-
- Before this patch, when a breakpoint that has multiple locations is reached,
- GDB printed:
- Thread 1 "zeoes" hit Breakpoint 1, some_func () at somefunc1.c:5
-
- This patch changes the message so that bkpt_print_id prints the precise
- encountered breakpoint:
- Thread 1 "zeoes" hit Breakpoint 1.2, some_func () at somefunc1.c:5
-
- In mi mode, bkpt_print_id also (optionally) prints a new table field "locno":
- locno is printed when the breakpoint hit has more than one location.
- Note that according to the GDB user manual node 'GDB/MI Development and Front
- Ends', it is ok to add new fields without changing the MI version.
-
- Also, when a breakpoint is reached, the convenience variables
- $_hit_bpnum and $_hit_locno are set to the encountered breakpoint number
- and location number.
-
- $_hit_bpnum and $_hit_locno can a.o. be used in the command list of a
- breakpoint, to disable the specific encountered breakpoint, e.g.
- disable $_hit_bpnum.$_hit_locno
-
- In case the breakpoint has only one location, $_hit_locno is set to
- the value 1, so as to allow a command such as:
- disable $_hit_bpnum.$_hit_locno
- to disable the breakpoint even when the breakpoint has only one location.
-
- This also fixes a strange behaviour: when a breakpoint X has only
- one location,
- enable|disable X.1
- is accepted but transforms the breakpoint in a multiple locations
- breakpoint having only one location.
-
- The changes in RFA v4 handle the comments of Tom Tromey:
- - Changed convenience var names from $bkptno/$locno to
- $_hit_bpnum/$_hit_locno.
- - updated the tests and user manual accordingly.
- User manual also explictly describes that $_hit_locno is set to 1
- for a breakpoint with a single location.
- - The variable values are now set in bpstat_do_actions_1 so that
- they are set for silent breakpoints, and when several breakpoints
- are hit at the same time, that the variables are set to the printed
- breakpoint.
-
- The changes in RFA v3 handle the additional comments of Eli:
- GDB/NEW:
- - Use max 80-column
- - Use 'code location' instead of 'location'.
- - Fix typo $bkpno
- - Ensure that disable $bkptno and disable $bkptno.$locno have
- each their explanation inthe example
- - Reworded the 'breakpoint-hit' paragraph.
- gdb.texinfo:
- - Use 'code location' instead of 'location'.
- - Add a note to clarify the distinction between $bkptno and $bpnum.
- - Use @kbd instead of examples with only one command.
-
- Compared to RFA v1, the changes in v2 handle the comments given by
- Keith Seitz and Eli Zaretskii:
- - Use %s for the result of paddress
- - Use bkptno_numopt_re instead of 2 different -re cases
- - use C@t{++}
- - Add index entries for $bkptno and $locno
- - Added an example for "locno" in the mi interface
- - Added examples in the Break command manual.

- gdbserver: use current_process in ps_getpid
- The following patch ("gdbserver: switch to right process in
- find_one_thread") makes it so find_one_thread calls into libthread_db
- with a current process but no current thread. This tripped on ps_getpid
- using current_thread in order to get the process' pid. Get the pid from
- `current_process ()` instead, which removes the need to have a current
- thread. Eventually, it would be good to get it from the
- gdb_ps_prochandle_t structure, to avoid the need for a current process
- as well.

- gdbserver/linux-x86: make is_64bit_tdesc accept thread as a parameter
- ps_get_thread_area receives as a parameter the lwpid it must work on.
- It then calls is_64bit_tdesc, which uses the current_thread as the
- thread to work on. However, it is not said that both are the same.
-
- This became a problem when working in a following patch that makes
- find_one_thread switch to a process but to no thread (current_thread ==
- nullptr). When libthread_db needed to get the thread area,
- is_64bit_tdesc would try to get the regcache of a nullptr thread.
-
- Fix that by making is_64bit_tdesc accept the thread to work on as a
- parameter. Find the right thread from the context, when possible (when
- we know the lwpid to work on). Otherwise, pass "current_thread", to
- retain the existing behavior.

- gdb/testsuite: rewrite gdb.cp/call-method-register.exp with dwarf assembler
- Convert the gdb.cp/call-method-register.exp test to make use of the
- DWARF assembler.
-
- The existing gdb.cp/call-method-register.exp test relies on a GCC
- extension - forcing a local variable into a particular named register.
-
- This means that the test will only work with Clang, and, as we have to
- name the register into which the variable will be placed, will only
- work for those targets where we've selected a suitable register,
- currently this is x86-64, i386, and ppc64.
-
- By switching to the DWARF assembler, the test will work with gcc and
- clang, and should work on most, if not all, architectures.
-
- The test creates a small structure, something that can fit within a
- register, and then tries to call a method on the structure from within
- GDB. This should fail because GDB can't take the address of the in
- register structure (for the `this` pointer).
-
- As the test is for a failure case, then we don't really care _which_
- register the structure is in, and I take advantage of this for the
- DWARF assembler test, I just declare that the variable is in
- DW_OP_reg0, whatever that might be. I've tested the new test on
- x86-64, ppc, aarch64, and risc-v, and the test runs, and passes on all
- these architectures, which is already more than we used to cover.
-
- Additionally, on x86-64, I've tested with Clang and gcc, and the test
- runs and passed with both compilers.

- gdb/testsuite: fix gdb.debuginfod/fetch_src_and_symbols.exp with Clang
- The gdb.debuginfod/fetch_src_and_symbols.exp test is showing a single
- failure when run with some older versions of Clang, e.g. 9.0.1.
-
- The problem appears to be with Clang's generated line table. The test
- source looks like this:
-
- int
- main()
- {
- asm ("main_label: .globl main_label");
- return 0;
- }
-
- In GDB, when we 'start', we expect to stop at the 'return 0;' line.
- This is the behaviour when the compiler is gcc, or later versions of
- Clang.
-
- However, with Clang 9.0.2, I see GDB stop on the 'asm' line.
-
- In this commit I'll fix this issue by placing a breakpoint on the
- return line, and then using gdb_continue_to_breakpoint to ensure we
- have stopped in the correct place.
-
- Of course, using gdb_continue_to_breakpoint will only work if we are
- not already stopped at the breakpoint location, so I've added some
- filler work before the 'return 0;' line. With this done we can use
- gdb_continue_to_breakpoint in all cases.
-
- As a result of adding the new filler work, one of the later tests,
- that used the 'list' command, no longer see the correct expected
- output (the top line of the source file is no longer included in the
- output). I've fixed this by listing a known specific line, the test
- is checking that GDB managed to find the source file, it doesn't
- matter which source line we list, as long as we can list something.

- gdb/testsuite: add (and use) a new build-id compile option
- I noticed that the gdb.debuginfod/fetch_src_and_symbols.exp test was
- failing when run with Clang as the compiler.
-
- This test relies on the compiled binaries having a build-id within
- them. For GCC, really GNU ld, the default is to always include a
- build-id.
-
- When compiling with Clang though, the default is for no build-id.
-
- I did consider *always* turning on the build-id feature when the
- compiler is Clang, but that felt a little weird.
-
- Instead, I propose that we add a new 'build-id' compiler option to
- gdb_compile, this flag indicates that the test _requires_ a build-id.
- In gcc_compile we can then add the required flags if the compiler is
- Clang so that we do get a build-id.
-
- With this change the gdb.debuginfod/fetch_src_and_symbols.exp test
- now (mostly) passes with Clang 9.0.1 and 15.0.2, and still passes with

- gdb/testsuite: fix gdb.compile/compile-ops.exp with clang
- I noticed that the gdb.compile/compile-ops.exp test was failing when
- run with Clang as the compiler.
-
- This test makes use of the DWARF assembler, and, it turns out, uses
- a technique which is not portable to Clang. This problem is
- described in the comment on the function_range proc in lib/dwarf.exp,
- the explanation is:
-
- # If the compiler is gcc, we can do the following to get function start
- # and end address too:
- #
- # asm ("func_start: .globl func_start");
- # static void func (void) {}
- # asm ("func_end: .globl func_end");
- #
- # however, this isn't portable, because other compilers, such as clang,
- # may not guarantee the order of global asms and function. The code
- # becomes:
- #
- # asm ("func_start: .globl func_start");
- # asm ("func_end: .globl func_end");
- # static void func (void) {}
-
- These start/end labels are used for computing the function start, end,
- and length. The portable solution is to place a label within the
- function, like this:
-
- # int main (void)
- # {
- # asm ("main_label: .globl main_label");
- # return 0;
- # }
-
- And make use of 'proc function_range' (from lib/dwarf.exp).
-
- So, that's what I do in this commit.
-
- One consequence of this change is that we need to compile the source
- file, and have it loaded into a GDB session, before calling
- function_range, so I've added an early call to prepare_for_testing.
-
- Additionally, this test script was generating the DWARF assembler into
- a file called gdbjit-ops.S, I suspect a copy and paste issue there, so
- I've switched this to use compile-ops-dbg.S instead, which is more
- inline with what other DWARF assembler tests do.
-
- The only other change, which might be a problem, is that I also
- deleted these two lines from the source file:
-
- asm (".section \".text\"");
- asm (".balign 8");
-
- These lines were setting the alignment of the .text section. What I
- don't know is whether this was significant or not. If it is
- significant, then I can't see why.
-
- On x86-64, the test still passes fine without these lines, but that
- doesn't mean the test wont start failing on some other architecture.
-
- Still, I figure, lets remove them, then, if/when we find a test that
- starts failing, we can add the lines back, along with an explanation
- for why the extra alignment is required.
-
- But, if people would prefer to be more conservative, then I'm happy to
- just add the lines back.

- gdb/testsuite: fix gdb.trace/unavailable-dwarf-piece.exp with Clang
- I noticed that the test gdb.trace/unavailable-dwarf-piece.exp was
- failing when run with Clang. Or rather, the test was not running as
- the test executable failed to compile.
-
- The problem is that Clang was emitting this warning:
-
- warning: argument unused during compilation: '-fdiagnostics-color=never' [-Wunused-command-line-argument]
-
- This warning is emitted when compiling the assembler file generated
- by the DWARF assembler.
-
- Most DWARF assembler tests generate the assembler file into a file
- with the '.S' extension. However, this particular test uses a '.s'
- extension.
-
- Now a .S file will be passed through the preprocessor, while a .s will
- be sent straight to the assembler. My guess is that Clang doesn't
- support the -fdiagnostics-color=never option for the assembler, but
- does for the preprocessor.
-
- That's a little annoying, but easily worked around. We don't care if
- our assembler file is passed through the preprocessor, so, in this
- commit, I just change the file extension from .s to .S, and the
- problem is fixed.
-
- Currently, the unavailable-dwarf-piece.exp script names the assembler
- file using standard_output_file, in this commit I've switched to make
- use of standard_testfile, as that seems to be the more common way of
- doing this sort of thing.
-
- With these changes the test now passes with Clang 9.0.1 and 15.0.2,

- (gdb) FAIL: gdb.python/py-send-packet.exp: call python run_auxv_send_packet_test function
-
- The test uses 'maint packet ...' to send a packet to gdbserver, and
- then captures the output in TCL. This output is then passed through
- to a Python function, which performs some actions using the Python
- API, and compares the results from the Python API to the results
- captured in TCL from 'maint packet ...'.
-
- The problem is that the output captured in TCL contains lots of things
- like '\x000', when this is passed through to Python the '\x' causes
- this to be treated as an escape code, which isn't what we want - we
- want the actual string "\x000".
-
- So, in the TCL part of the test we were expanding '\x' to '\\x', this
- seemed to work fine for my testing on x86-64.
-
- However, on AArch64 what I see is that the results from 'maint packet
- ...' contain a literal '\' character followed by a literal 'x'
- character. When GDB prints this in the 'maint packet' output, GDB
- escapes the '\' for us, thus we get '\\x' printed by 'maint packet'.
-
- However, now our TCL test script kicks in and tries to "fix" the '\x',
- this means we now have '\\\x', which isn't correct.
-
- The problem is that in the TCL script we are too restrictive, we
- expand '\x' to '\\x', but really, we should be expanding all '\'
- characters, regardless of what follows them. This is what this patch
- does.
-
- After this the gdb.python/py-send-packet.exp test passes on AArch64
- for me.

- gdb/fortran/testsuite: print values and types of string variables
- While looking through the Fortran tests, I couldn't find a test of GDB
- printing the value and type of a Fortran string defined using the
- 'character*SIZE' notation.
-
- This works fine in GDB right now, but I thought it wouldn't hurt to
- have a test for this, so this commit adds such a test.
-
- The test also includes printing a string that includes some embedded
- special characters: \n \r \t \000 - that's right, as Fortran strings
- are stored as an address and length, it is fine to include an embedded
- null, so this test includes an example of that.
-
- Standard Fortran doesn't support backslash escape sequences within
- strings, the special characters must be generated using the `achar`
- function. However, when GDB prints the strings we currently print
- using the standard C like backslash sequences.
-
- I'm not currently proposing to change that behaviour, the backslash
- sequences are more compact than the standard Fortran way of doing
- things, and are so widely used that I suspect most Fortran programmers
- will understand them.

- Fix various procfs.c compilation errors
- procfs.c has accumulated several compilation errors lately (some of them
- new with GCC 12), which are fixed by this patch:
-
- * auxv_parse gets:
-
- /vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c:144:7: error: \91int
- procfs_target::auxv_parse(gdb_byte**, gdb_byte*, CORE_ADDR*, CORE_ADDR*)\92
- marked \91override\92, but does not override
- 144 | int auxv_parse (gdb_byte **readptr,
- | ^~~~~~~~~~
-
- Obviouly, procfs.c was missed in the auxv_parse constification.
-
- * dead_procinfo has:
-
- /vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c: In function \91void
- dead_procinfo(procinfo*, const char*, int)\92:
- /vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c:563:11: warning: the address
- of \91procinfo::pathname\92 will never be NULL [-Waddress]
- 563 | if (pi->pathname)
- | ~~~~^~~~~~~~
- /vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c:238:8: note:
- \91procinfo::pathname\92 declared here
- 238 | char pathname[MAX_PROC_NAME_SIZE]; /* Pathname to /proc entry */
- | ^~~~~~~~
-
- The warning is correct, so the code can lose support for the NULL
- pathname case.
-
- * create_inferior has this ugly warning:
-
- /vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c: In member function \91virtual void procfs_target::create_inferior(const char*, const std::string&, char**, int)\92:
- /vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c:2815:19: warning: \91char* std::strncpy(char*, const char*, size_t)\92 output truncated before terminating nul copying as many bytes from a string as its length [-Wstringop-truncation]

- /vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c:2814:26: note: length computed here
- 2814 | len = strlen (p);
- | ~~~~~~~^~~
-
- It seems that this is another case of GCC PR middle-end/88059, which
- Martin Sebor refuses to fix. So I'm using the hack suggested in the
- PR to use memcpy instead of strncpy.
-
- * find_memory_regions_callback fails with

- bfd: linker: merge .sframe sections
- The linker merges all the input .sframe sections. When merging, the
- linker verifies that all the input .sframe sections have the same
- abi/arch.
-
- The linker uses libsframe library to perform key actions on the
- .sframe sections - decode, read, and create output data. This
- implies buildsystem changes to make and install libsframe before
- libbfd.
-
- The linker places the output .sframe section in a new segment of its
- own: PT_GNU_SFRAME. A new segment is not added, however, if the
- generated .sframe section is empty.
-
- When a section is discarded from the final link, the corresponding
- entries in the .sframe section for those functions are also deleted.
-
- The linker sorts the SFrame FDEs on start address by default and sets
- the SFRAME_F_FDE_SORTED flag in the .sframe section.
-
- This patch also adds support for generation of SFrame unwind
- information for the .plt* sections on x86_64. SFrame unwind info is
- generated for IBT enabled PLT, lazy/non-lazy PLT.
-
- The existing linker option --no-ld-generated-unwind-info has been
- adapted to include the control of whether .sframe unwind information
- will be generated for the linker generated sections like PLT.

- Changes to the linker script have been made as necessary.

- libsframe: add the SFrame library
- libsframe is a library that allows you to:
- - decode a .sframe section
- - probe and inspect a .sframe section
- - encode (and eventually write) a .sframe section.
-
- This library is currently being used by the linker, readelf, objdump.
- This library will also be used by the SFrame unwinder which is still
- to be upstream'd.
-
- The file include/sframe-api.h defines the user-facing APIs for decoding,
- encoding and probing .sframe sections. A set of error codes together
- with their error message strings are also defined.
-
- Endian flipping is performed automatically at read and write time, if
- cross-endianness is detected.

-
- gas: generate .sframe from CFI directives
- Currently supported for x86_64 and aarch64 only.
-
- [PS: Currently, the compiler has not been adapted to generate
- ".cfi_sections" with ".sframe" in it. The newly added command line
- option of --gsframe provides an easy way to try out .sframe support
- in the toolchain.]
-
- gas interprets the CFI directives to generate DWARF-based .eh_frame
- info. These internal DWARF structures are now consumed by
- gen-sframe.[ch] sub-system to, in turn, create the SFrame unwind
- information. These internal DWARF structures are read-only for the
- purpose of SFrame unwind info generation.
-
- SFrame unwind info generation does not impact .eh_frame unwind info
- generation. Both .eh_frame and .sframe can co-exist in an ELF file,
- if so desired by the user.
-
- Recall that SFrame unwind information only contains the minimal
- necessary information to generate backtraces and does not provide
- information to recover all callee-saved registers. The reason being
- that callee-saved registers other than FP are not needed for stack
- unwinding, and hence are not included in the .sframe section.
-
- Consequently, gen-sframe.[ch] only needs to interpret a subset of
- DWARF opcodes in gas. More details follow.
-
- [Set 1, Interpreted] The following opcodes are interpreted:
- - DW_CFA_advance_loc
- - DW_CFA_def_cfa
- - DW_CFA_def_cfa_register
- - DW_CFA_def_cfa_offset
- - DW_CFA_offset
- - DW_CFA_remember_state
- - DW_CFA_restore_state
- - DW_CFA_restore
-
- [Set 2, Bypassed] The following opcodes are acknowledged but are not
- necessary for generating SFrame unwind info:
- - DW_CFA_undefined
- - DW_CFA_same_value
-
- Anything else apart from the two above-mentioned sets is skipped
- altogether. This means that any function containing a CFI directive not
- in Set 1 or Set 2 above, will not have any SFrame unwind information
- generated for them. Holes in instructions covered by FREs of a single
- FDE are not representable in the SFrame unwind format.
-
- As few examples, following opcodes are not processed for .sframe
- generation, and are skipped:
- - .cfi_personality*
- - .cfi_*lsda
- - .cfi_escape
- - .cfi_negate_ra_state
- - ...
-
- Not processing .cfi_escape, .cfi_negate_ra_state will cause SFrame
- unwind information to be absent for SFrame FDEs that contain these CFI
- directives, hence affecting the asynchronicity.
-
- x86-64 and aarch64 backends need to have a few new definitions and
- functions for .sframe generation. These provide gas with architecture
- specific information like the SP/FP/RA register numbers and an
- SFrame-specific ABI marker.
-
- Lastly, the patch also implements an optimization for size, where
- specific fragments containing SFrame FRE start address and SFrame FDE
- function are fixed up. This is similar to other similar optimizations
- in gas, where fragments are sized and fixed up when the associated
- symbols can be resolved. This optimization is controlled by a #define
- SFRAME_FRE_TYPE_SELECTION_OPT and should be easy to turn off if needed.
- The optimization is on by default for both x86_64 and aarch64.

- gdb/configure: regenerate
- The commit bbaabc767a4293492817a0840819aef2768cce90 introduced an

-
- gdb: use libtool in GDB_AC_CHECK_BFD
- The GDB_AC_CHECK_BFD macro defined in gdb/acinclude.m4 uses the
- AC_LINK_IFELSE autoconf macro in order to link a simple program to
- check features of libbfd.
-
- If libbfd's link dependencies change, it was necessary to reflect them
- either in the definition of the macro, or as a consequence of checking
- for them with an autoconf macro resulting in an addition to LIBS.
-
- This patch modifies the definition of the GDB_CHECK_BFD macro in order
- to use libtool to perform the test link. This makes it possible to
- not have to list dependencies of libbfd (which are indirect to GDB) at
- all.
-
- After this patch:
-
- configure:28553: checking for ELF support in BFD
- configure:28573: ./libtool --quiet --mode=link gcc -o conftest \
- -I../../gdb/../include -I../bfd \

- -lncursesw -lm -ldl >&5
- configure:28573: $? = 0
- configure:28583: result: yes
-
- Tests performed:
-
- - Configure --with-system-zlib and --without-system-zlib.
- - Check link dependencies of installed GDB with both --enable-shared
- and --disable-shared.
- - Run installed GDB in both cases.

- gdb/testsuite: get_set_option_choices: expect \r\n after each item
- I get some random failures since commit 8d45c3a82a0e ("[gdb/testsuite]
- Set completions to unlimited in get_set_option_choices"), which can be
- reproduced with:
-
- $ make check-read1 TESTS="gdb.base/parse_number.exp"
-
- For instance:
-
- set architecture A^M
- Ambiguous item "A".^M
- (gdb) FAIL: gdb.base/parse_number.exp: arch=A: set architecture A
-
- The problem is the regexp in get_set_option_choices, it is possible that
- is only matches part of a completion result. With check-read1, that is
- always one letter.
-
- Fix this by expecting the \r\n at the end of the line, so we only match
- entire results. Use ^ in match patterns to ensure we don't miss any
- output.

- [gdb/testsuite] Add REMOTE_TARGET_USERNAME in remote-gdbserver-on-localhost.exp
- As reported here
- ( https://sourceware.org/pipermail/gdb-patches/2022-October/193147.html ) a
- number of test-cases fails with a remote target setup, for instance test-case
- gdb.base/print-file-var.exp.
-
- So, why don't we see these fails with our remote target boards in
- gdb/testsuite/boards, say remote-gdbserver-on-localhost.exp?
-
- The problem is that the target board uses the same machine and user for
- both (by-definition-local) build and remote target, and when using absolute
- pathnames to refer to files on build, we can access those files on target,
- which in a real remote target setup wouldn't be the case: we'd have to
- download them to target first, and then the filename would also be different.
-
- For aforementioned test-case, this happens when the name of a shared library is
- passed as absolute file name to gcc:
- ...
- gcc ... -DSHLIB_NAME="$outputs/gdb.base/print-file-var/\
- print-file-var-lib2-hidden0-dlopen1-version_id_main0_c.so"
- ...
-
- Make these problems visible with remote-gdbserver-on-localhost.exp by
- adding an option to specify a test account (still on the same machine)
- using REMOTE_TARGET_USERNAME.
-
- We make sure by restricting file permissions, that the test account cannot see
- the build files on the $USER account, and that the $USER account cannot see
- the target files on the test account.
-
- And so we can reproduce the reported fails:
- ...
- $ cd build/gdb
- $ tc="gdb.base/print-file-var.exp"
- $ tb="--target_board remote-gdbserver-on-localhost"
- $ tbu="REMOTE_TARGET_USERNAME=remote-target"
- $ make check RUNTESTFLAGS="$tb $tbu $tc"
- ...
- FAIL: gdb.base/print-file-var.exp: lang=c: hidden=0: dlopen=1: \
- version_id_main=0: continue to STOP marker
- ...
-
- Tested on x86_64-linux.

- [gdb/testsuite] Fix gdb.base/foll-exec.exp for remote target
- When running test-case gdb.base/foll-exec.exp with target board

- PowerPC, fix support for printing the function return value for non-trivial values.
- Currently, a non-trivial return value from a function cannot currently be
- reliably determined on PowerPC. This is due to the fact that the PowerPC
- ABI uses register r3 to store the address of the buffer containing the
- non-trivial return value when the function is called. The PowerPC ABI
- does not guarantee the value in register r3 is not modified in the
- function. Thus the value in r3 cannot be reliably used to obtain the
- return addreses on exit from the function.
-
- This patch adds a new gdbarch method to allow PowerPC to access the value
- of r3 on entry to a function. On PowerPC, the new gdbarch method attempts
- to use the DW_OP_entry_value for the DWARF entries, when exiting the
- function, to determine the value of r3 on entry to the function. This
- requires the use of the -fvar-tracking compiler option to compile the
- user application thus generating the DW_OP_entry_value in the binary. The
- DW_OP_entry_value entries in the binary file allows GDB to resolve the
- DW_TAG_call_site entries. This new gdbarch method is used to get the
- return buffer address, in the case of a function returning a nontrivial
- data type, on exit from the function. The GDB function should_stop checks
- to see if RETURN_BUF is non-zero. By default, RETURN_BUF will be set to
- zero by the new gdbarch method call for all architectures except PowerPC.
- The get_return_value function will be used to obtain the return value on
- all other architectures as is currently being done if RETURN_BUF is zero.
- On PowerPC, the new gdbarch method will return a nonzero address in
- RETURN_BUF if the value can be determined. The value_at function uses the
- return buffer address to get the return value.
-
- This patch fixes five testcase failures in gdb.cp/non-trivial-retval.exp.
- The correct function return values are now reported.
-
- Note this patch is dependent on patch: "PowerPC, function
- ppc64_sysv_abi_return_value add missing return value convention".
-
- This patch has been tested on Power 10 and x86-64 with no regressions.

- gdb: on x86-64 non-trivial C++ objects are returned in memory
-
- Fixes PR gdb/28681. It was observed that after using the `finish`
- command an incorrect value was displayed in some cases. Specifically,
- this behaviour was observed on an x86-64 target.
-
- The function:
-
- enum return_value_convention
- ppc64_sysv_abi_return_value (struct gdbarch *gdbarch, struct value *function,
- struct type *valtype, struct regcache *regcache,
- gdb_byte *readbuf, const gdb_byte *writebuf)
-
- should return RETURN_VALUE_STRUCT_CONVENTION if the valtype->code() is
- TYPE_CODE_STRUCT and if the language_pass_by_reference is not
- trivially_copyable.
-
- This patch adds the needed code to return the value
- RETURN_VALUE_STRUCT_CONVENTION in this case.
-
- With this patch, the five test cases still fail but with the message "Value
- returned has type: A. Cannot determine contents". The PowerPC ABI stores
- the address of the buffer containing the function return value in register
- r3 on entry to the function. However, the PowerPC ABI does not guarentee
- that r3 will not be modified in the function. So when the function returns,
- the return buffer address cannot be reliably obtained from register r3.
- Thus the message "Cannot determine contents" is appropriate in this case.

- gdb/unittests: PR28413, suppress warnings generated by Gnulib
- Gnulib generates a warning if the system version of certain functions
- are used (to redirect the developer to use Gnulib version). It caused a
- compiler error when...
-
- - Compiled with Clang
- - -Werror is specified (by default)
- - C++ standard used by Clang is before C++17 (by default as of 15.0.0)
- when this unit test is activated.
-
- This issue is raised as PR28413.
-
- However, previous proposal to fix this issue (a "fix" to Gnulib):
- <https://lists.gnu.org/archive/html/bug-gnulib/2021-10/msg00003.html>
- was rejected because it ruins the intent of Gnulib warnings.
-
- So, we need a Binutils/GDB-side solution.
-
- This commit tries to address this issue on the GDB side. We have
- "include/diagnostics.h" to disable certain warnings only when necessary.
-
- This commit suppresses the Gnulib warnings by surrounding entire #include
- block with DIAGNOSTIC_IGNORE_USER_DEFINED_WARNINGS to disable Gnulib-
- generated warnings on all standard C++ header files.

- gdb: fix start breakpoint expression not working in some languages
- Commit 0be837be9fb4 ("gdb: make "start" breakpoint inferior-specific")
- regresses gdb.ada/start.exp:
-
- (gdb) start
- Error in expression, near `1'.
- (gdb) UNTESTED: gdb.ada/start.exp: start failed to land inside the right procedure
-
- This is because in Ada, the equality operator is =, not ==.
-
- I checked the other languages supported by GDB, these other languages
- use = for equality:
-
- - Pascal: tests like gdb.pascal/hello.exp are affected too
- - Modula-2: I tried building a Modula-2 hello world using gm2, but it
- seems like the generated DWARF doesn't specify the Modula-2 language
- in the CUs, it's C++ and C, so the selected language isn't
- "modula-2". But if I manually do "set language modula-2" on a dummy
- program and then "start", I get the same error.
-
- Other languages all use ==.
-
- So, a short term fix would be to use = or == in the expression, based on
- the current language. If this was meant to be permanent, I would
- suggest adding something like an "equality_operator" method to
- language_defn, that returns the right equality operator for the
- language. But the goal is to replace all this with proper
- inferior-specific breakpoints, so I hope all this is temporary.

- [gdb/testsuite] Better error checking in has_hw_wp_support
- With gdb 12.1, on powerpc64le I ran into ERRORs related to has_hw_wp_support
- usage, which was already fixed on trunk by commits:
- - 13f72372413 ("gdb/testsuite: fix gdb.base/break-idempotent.exp on ppc"), and
- - 01a32ee0b8c ("PowerPC, fix gdb.base/watchpoint.exp on Power 9")
-
- While looking into these ERRORs and the commits that fix them, it occurred to
- me that while the commits fix the root cause, the failure mode is not great.
-
- The test-cases expect a running instance of gdb upon return, which is not
- there, so there's an long stream of ERRORs generated as a result.
-
- Fix this at the start of has_hw_wp_support, by (instead of accomodating a
- running gdb instance by calling gdb_exit), checking whether it's called
- without a running gdb instance, and erroring out otherwise. This way, there's
- just one error.
-
- I also noticed that in case we do an early exit due to !runto_main, we don't
- clean up, so copy the missing cleanups (gdb_exit and $obj file deletion) from
- the regular exit.
-
- Tested on x86_64-linux, using has_hw_wp_support for x86_64 in
- skip_hw_watchpoint_tests.

- gdb/py-inferior: Keep inferior threads in a map
- The python code maintains a list of threads for each inferior. This
- list is implemented as a linked list. When the number of threads grows
- high, this implementation can begin to be a performance bottleneck as
- finding a particular thread_object in the list has a complexity of O(N).
-
- We see this in ROCgdb[1], a downstream port of GDB for AMDGUP. On
- AMDGPU devices, the number of threads can get significantly higher than
- on usual GDB workloads.
-
- In some situations, we can reach the end of the inferior process with
- GDB still having a substantial list of known threads. While running
- target_mourn_inferior, we end up in inferior::clear_thread_list which
- iterates over all remaining threads and marks each thread exited. This
- fires the gdb::observers::thread_exit observer and eventually
- py-inferior.c:set_thread_exited gets called. This function searches in
- the linked list with poor performances.
-
- This patch proposes to change the linked list that keeps the per
- inferior_object list of thread_objects into a std::unordered_map. This
- allows to have the search operation complexity be O(1) on average
- instead of O(N).
-
- With this patch, we can complete clear_thread_list in about 2.5 seconds
- compared to 10 minutes without it.
-
- Except for the performance change, no user visible change is expected.
-
- Regression tested on Ubuntu-22.04 x86_64.

- Make sure a copy_insn_closure is available when we have a match in copy_insn_closure_by_addr
- PR gdb/29272
-
- Investigating PR29272, it was mentioned a particular test used to work on
- GDB 10, but it started failing with GDB 11 onwards. I tracked it down to
- some displaced stepping improvements on commit
- 187b041e2514827b9d86190ed2471c4c7a352874.
-
- In particular, one of the corner cases using copy_insn_closure_by_addr got
- silently broken. It is hard to spot because it doesn't have any good tests
- for it, and the situation is quite specific to the Arm target.
-
- Essentially, the change from the displaced stepping improvements made it so
- we could still invoke copy_insn_closure_by_addr correctly to return the
- pointer to a copy_insn_closure, but it always returned nullptr due to
- the order of the statements in displaced_step_buffer::prepare.
-
- The way it is now, we first write the address of the displaced step buffer
- to PC and then save the copy_insn_closure pointer.
-
- The problem is that writing to PC for the Arm target requires figuring
- out if the new PC is thumb mode or not.
-
- With no copy_insn_closure data, the logic to determine the thumb mode
- during displaced stepping doesn't work, and gives random results that
- are difficult to track (SIGILL, SIGSEGV etc).
-
- Fix this by reordering the PC write in displaced_step_buffer::prepare
- and, for safety, add an assertion to
- displaced_step_buffer::copy_insn_closure_by_addr so GDB stops right
- when it sees this invalid situation. If this gets broken again in the
- future, it will be easier to spot.

- gdb/testsuite: skip gdb.cp/anon-struct.exp when using Clang
- When Clang compiles anonymous structures, it does not add linkage names in
- their dwarf representations. This is compounded by Clang not adding linkage
- names to subprograms of those anonymous structs (for instance, the
- constructor). With these 2 things together, GDB is unable to refer to
- any of them, so there is no way to pass any of the tests of
- gdb.cp/anon-struct.exp
-
- Since this isn't a bug on Clang or GDB according to the DWARF

- gdb/testsuite: account for clang's nested destructor calls on gdb.cp/mb-ctor.exp
- When compiling virtual classes's destructors, two versions are compiled,
- one with a single parameter (this) and the other with 2 parameters (this
- and vtt).
-
- GCC's compilation makes it so either the version with 1
- parameter or the one with 2 parameters is called, depending on whether
- the destructor is being called by the class itself or by an inherited
- class. On the test gdb.cp/mb-ctor.exp, this means that the breakpoint
- set at the destructor will be hit 4 times.
-
- Clang, on the other hand, makes the single-parameter version call the 2
- parameter version, probably in an attempt to reduce the size of the
- resulting executable. This means that the gdb.cp/mb-ctor.exp will hit 6
- breakpoints before finishing, and is the reason why this test was
- failing. To make this test stop failing, a compiler check is added and
- another "continue" instruction is issued to account for this difference.

- gdb/testsuite: enable running gdb.cp/classes.exp with clang
- When attempting to run the gdb.cp/classes.exp test using Clang++, the
- test fails to prepare with -Wnon-c-typedef-for-linkage like the

- unexpected failures. One such failures is:
-
- ptype/r class class_with_public_typedef
- type = class class_with_public_typedef {

- (gdb) FAIL: gdb.cp/classes.exp: ptype class class_with_public_typedef // wrong access specifier for typedef: private

- class_with_public_typedef::INT b;
-
- typedef int INT;
- }
- (gdb) PASS: gdb.cp/classes.exp: ptype class class_with_public_typedef
-
- This error happens because Clang does not add DW_AT_accessibility to
- typedefs inside classes, and without this information GDB defaults to
- assuming the typedef is private. Since there is nothing that GDB can do
- about this, these tests have been set as xfails, and Clang bug 57608 has

- possible to insert a breakpoint in one inferior but not the other.
-
- A simple solution that should work all the time is to add a condition to
- the breakpoint inserted by "start", to check the inferior reporting the
- hit is the expected one. This is what this patch implements.
-
- Add a test that does:
-
- - start in background inferior 1 that sleeps before reaching its main
- function (using a sleep in a global C++ object's constructor)
- - start inferior 2 with the "start" command, which also sleeps before
- reaching its main function
- - validate that we hit the breakpoint in inferior 2
-
- Without the fix, we hit the breakpoint in inferior 1 pretty much all the
- time. There could be some unfortunate scheduling causing the test not
- to catch the bug, for instance if the scheduler decides not to schedule
- inferior 1 for a long time, but it would be really rare. If the bug is
- re-introduced, the test will catch it much more often than not, so it
- will be noticed.

- gdb: add special handling for frame level 0 in frame_info_ptr
- I noticed this problem while preparing the initial submission for the
- ROCm GDB port. One particularity of this patch set is that it does not
- support unwinding frames, that requires support of some DWARF extensions
- that will come later. It was still possible to run to a breakpoint and
- print frame #0, though.
-
- When rebasing on top of the frame_info_ptr work, GDB started tripping on
- a prepare_reinflate call, making it not possible anymore to event print
- the frame when stopping on a breakpoint. One thing to know about frame
- 0 is that its id is lazily computed when something requests it through
- get_frame_id. See:
-
- https://gitlab.com/gnutools/binutils-gdb/-/blob/23912acd402f5af9caf91b257e5209ec4c58a09c/gdb/frame.c#L2070-2080
-
- So, up to that prepare_reinflate call, frame 0's id was not computed,
- and prepare_reinflate, calling get_frame_id, forces it to be computed.
- Computing the frame id generally requires unwinding the previous frame,
- which with my ROCm GDB patch fails. An exception is thrown and the
- printing of the frame is simply abandonned.
-
- Regardless of this ROCm GDB problem (which is admittedly temporary, it
- will be possible to unwind with subsequent patches), we want to avoid
- prepare_reinflate to force the computing of the frame id, for the same
- reasons we lazily compute it in the first place.
-
- In addition, frame 0's id is subject to change across a frame cache
- reset. This is why save_selected_frame and restore_selected_frame have
- special handling for frame 0:
-
- https://gitlab.com/gnutools/binutils-gdb/-/blob/23912acd402f5af9caf91b257e5209ec4c58a09c/gdb/frame.c#L1841-1863
-
- For this last reason, we also need to handle frame 0 specially in
- prepare_reinflate / reinflate. Because the frame id of frame 0 can
- change across a frame cache reset, we must not rely on the frame id from
- that frame to reinflate it. We should instead just re-fetch the current
- frame at that point.
-
- This patch adds a frame_info_ptr::m_cached_level field, set in
- frame_info_ptr::prepare_reinflate, so we can tell if a frame is frame 0.
- There are cases where a frame_info_ptr object wraps a sentinel frame,
- for which frame_relative_level returns -1, so I have chosen the value -2
- to represent "invalid frame level", for when the frame_info_ptr object
- is empty.
-
- In frame_info_ptr::prepare_reinflate, only cache the frame id if the
- frame level is not 0. It's fine to cache the frame id for the sentinel
- frame, it will be properly handled by frame_find_by_id later.
-
- In frame_info_ptr::reinflate, if the frame level is 0, call
- get_current_frame to get the target's current frame. Otherwise, use
- frame_find_by_id just as before.
-
- This patch should not have user-visible changes with upstream GDB. But
- it will avoid forcing the computation of frame 0's when calling
- prepare_reinflate. And, well, it fixes the upcoming ROCm GDB patch
- series.

- gdb: add missing prepare_reinflate call in print_frame_info
- print_frame_info calls frame_info_ptr::reinflate, but not
- frame_info_ptr::prepare_reinflate, add the call to prepare_reinflate.
- It works right now, because all callers of print_frame_info that could
- possibly lead to the pretty printers being called, and the frame_info
- objects being invalidated, do call prepare_reinflate themselves. And
- since the cached frame id is copied when passing a frame_info_ptr by
- value, print_frame_info does have a cached frame id on entry. So
- technically, this change isn't needed. But I don't think it's good for
- a function to rely on its callers to have called prepare_reinflate, if
- it intends to call reinflate.

-
- This is because the code in backtrace_command_1 to manually reinflate
- `fi` steps overs frame_info_ptr's toes.
-
- When calling
-
- fi.prepare_reinflate ();
-
- `fi` gets properly filled with the cached frame id. But when this
- happens:
-
- fi = frame_find_by_id (frame_id);
-
- `fi` gets replaced by a brand new frame_info_ptr that doesn't have a
- cached frame id. Then this is called without a cached frame id:
-
- fi.reinflate ();
-
- That doesn't cause any problem currently, since
-
- - the gdb_assert in the reinflate method doesn't actually do anything
- (the following patch fixes that)
- - `fi.m_ptr` will always be non-nullptr, since we just got it from
- frame_find_by_id, so reinflate will not do anything, it won't try to
- use m_cached_id
-
- Fix that by removing the code to manually re-fetch the frame. That
- should be taken care of by frame_info_ptr::reinflate.
-
- Note that the old code checked if we successfully re-inflated the frame
- or not, and if not it did emit a warning. The equivalent in
- frame_info_ptr::reinflate asserts that the frame has been successfully
- re-inflated. It's not clear if / when this can happen, but if it can
- happen, we'll need to find a solution to this problem globally
- (everywhere a frame_info_ptr can be re-inflated), not just here. So I
- propose to leave it like this, until it does become a problem.

- When resolving overloaded functions, GDB relies on knowing relationships

-
- The problem is that sometimes the user may not know that the type

- of this.
-
- This commit also adds a testcase confirming that the message is only

- (gdb) FAIL: gdb.base/rtld-step-nodebugsym.exp: continue until exit (the program is no longer running)
-
- Without glibc debug info, GDB steps until the program finishes, and
- then "gdb_continue_to_end" fails.
-
- As this test was designed to check that GDB does not crash in the "step"

- Allow 'ptype/o' for assembly
- PR exp/28359 points out that 'ptype/o' does not work when the current
- language is "asm".
-
- I tracked this down to a hard-coded list of languages in typeprint.c.
- This patch replaces this list with a method on 'language_defn'
- instead. If all languages are ever updated to have this feature, the
- method could be removed; but in the meantime this lets each language

-
- I looked at having each print_type method simply modify the flags

- gdb/linux-nat: get core count using /sys/devices/system/cpu/possible
- I get this test failure on my CI;
-
- FAIL: gdb.base/info-os.exp: get process list
-
- The particularity of this setup is that builds are done in containers
- who are allocated 4 CPUs on a machine that has 40. The code in
- nat/linux-osdata.c fails to properly fetch the core number for each
- task.
-
- linux_xfer_osdata_processes uses `sysconf (_SC_NPROCESSORS_ONLN)`, which
- returns 4, so it allocates an array of 4 integers. However, the core
- numbers read from /proc/pid/task/tid/stat, by function
- linux_common_core_of_thread, returns a value anywhere between 0 and 39.
- The core numbers above 3 are therefore ignored, many processes end up
- with no core value, and the regexp in the test doesn't match (it
- requires an integer as the core field).
-
- The way this the CPUs are exposed to the container is that the container
- sees 40 CPUs "present" and "possible", but only 4 arbitrary CPUs
- actually online:
-
- root@ci-node-jammy-amd64-04-08:~# cat /sys/devices/system/cpu/present
- 0-39
- root@ci-node-jammy-amd64-04-08:~# cat /sys/devices/system/cpu/online
- 5,11,24,31
- root@ci-node-jammy-amd64-04-08:~# cat /sys/devices/system/cpu/possible
- 0-39
-
- The solution proposed in this patch is to find out the number of
- possible CPUs using /sys/devices/system/cpu/possible. In practice, this
- will probably always contain `0-N`, where N is the number of CPUs, minus
- one. But the documentation [1] doesn't such guarantee, so I'll assume
- that it can contain a more complex range list such as `2,4-31,32-63`,
- like the other files in that directory can have. The solution is to
- iterate over these numbers to find the highest possible CPU id, and
- use that that value plus one as the size of the array to allocate.

- [gdb/cli] Make quit really quit after remote connection closed
- Consider a hello world a.out, started using gdbserver:
- ...
- $ gdbserver --once 127.0.0.1:2345 ./a.out
- Process ./a.out created; pid = 15743
- Listening on port 2345
- ...
- that we can connect to using gdb:
- ...
- $ gdb -ex "target remote 127.0.0.1:2345"
- Remote debugging using 127.0.0.1:2345
- Reading /home/vries/a.out from remote target...
- ...
- 0x00007ffff7dd4550 in _start () from target:/lib64/ld-linux-x86-64.so.2
- (gdb)
- ...
-
- After that, we can for instance quit with confirmation:
- ...
- (gdb) quit
- A debugging session is active.
-
- Inferior 1 [process 16691] will be killed.
-
- Quit anyway? (y or n) y
- $
- ...
-
- Or, kill with confirmation and quit:
- ...
- (gdb) kill
- Kill the program being debugged? (y or n) y
- [Inferior 1 (process 16829) killed]
- (gdb) quit
- $
- ...
-
- Or, monitor exit, kill with confirmation, and quit:
- ...
- (gdb) monitor exit
- (gdb) kill
- Kill the program being debugged? (y or n) y
- Remote connection closed
- (gdb) quit
- $
- ...
-
- But when doing monitor exit followed by quit with confirmation, we get the gdb
- prompt back, requiring us to do quit once more:
- ...
- (gdb) monitor exit
- (gdb) quit
- A debugging session is active.
-
- Inferior 1 [process 16944] will be killed.
-
- Quit anyway? (y or n) y
- Remote connection closed
- (gdb) quit
- $
- ...
-
- So, the first quit didn't quit. This happens as follows:
- - quit_command calls query_if_trace_running
- - a TARGET_CLOSE_ERROR is thrown
- - it's caught in remote_target::get_trace_status, but then
- rethrown because it's TARGET_CLOSE_ERROR
- - catch_command_errors catches the error, at which point the quit command
- has been aborted.
-
- The TARGET_CLOSE_ERROR is defined as:
- ...
- /* Target throwing an error has been closed. Current command should be
- aborted as the inferior state is no longer valid. */
- TARGET_CLOSE_ERROR,
- ...
- so in a way this is expected behaviour. But aborting quit because the inferior
- state (which we've already confirmed we're not interested in) is no longer
- valid, and having to type quit again seems pointless.
-
- Furthermore, the purpose of not catching errors thrown by
- query_if_trace_running as per commit 2f9d54cfcef ("make -gdb-exit call
- disconnect_tracing too, and don't lose history if the target errors on
- "quit""), was to make sure that error (_("Not confirmed.") had effect.
-
- Fix this in quit_command by catching only the TARGET_CLOSE_ERROR exception
- during query_if_trace_running and reporting it:
- ...
- (gdb) monitor exit
- (gdb) quit
- A debugging session is active.
-
- Inferior 1 [process 19219] will be killed.
-
- Quit anyway? (y or n) y
- Remote connection closed
- $
- ...

- gdb: link executables with libtool
- This patch changes the GDB build system in order to use libtool to
- link the several built executables. This makes it possible to refer
- to libtool libraries (.la files) in CLIBS.
-
- As an application of the above,
-
- BFD now refers to ../libbfd/libbfd.la
- OPCODES now refers to ../opcodes/libopcodes.la
- LIBBACKTRACE_LIB now refers to ../libbacktrace/libbacktrace.la
- LIBCTF now refers to ../libctf/libctf.la
-
- NOTE1: The addition of libtool adds a few new configure-time options
- to GDB. Among these, --enable-shared and --disable-shared, which were
- previously ignored. Now GDB shall honor these options when linking,
- picking up the right version of the referred libtool libraries
- automagically.
-
- NOTE2: I have not tested the insight build.
-
- NOTE3: For regenerating configure I used an environment with Autoconf
- 2.69 and Automake 1.15.1. This should match the previously
- used version as announced in the configure script.
-
- NOTE4: Now the installed shared objects libbfd.so, libopcodes.so and
- libctf.so are used by gdb if binutils is installed with
- --enable-shared.
-
- Testing performed:
-
- - --enable-shared and --disable-shared (the default in binutils) work
- as expected: the linked executables link with the archive or shared
- libraries transparently.
-
- - Makefile.in modified for EXEEXT = .exe. It installs the binaries
- just fine. The installed gdb.exe runs fine.
-
- - Native build regtested in x86_64. No regressions found.

- Despite that the RISC-V ISA Manual version 2.2 prohibited "RV32EF", later

- Note that, because RV32E is only used with a soft-float calling convention,

- sim: build: respect AM_MAKEFLAGS when entering subdirs
- This doesn't matter right now, but it will as we add more flags to
- the recursive make step to pass state down.
-
- sim: build: stop passing down SIM_PRIMARY_TARGET
- This was needed when the install step was run in subdirs, but now
- that we process that entirely in the top-level, we don't need to
- pass this down, so drop it.

- Deprecate MI version 1
- MI version 1 is long since obsolete. Rather than remove it
- immediately (though I did send a patch for that), instead let's
- deprecate it in GDB 13 and then remove it for GDB 14.
-
- This version of the patch incorporates Simon's warning change, and

- sim: fix readline linkage
- Now that we link programs in the top dir instead of the arch subdir,
- update the readline library path to be relative to the top dir.

-
- sim: run: move linking into top-level
- Automake will run each subdir individually before moving on to the next
- one. This means that the linking phase, a single threaded process, will
- not run in parallel with anything else. When we have to link ~32 ports,
- that's 32 link steps that don't take advantage of parallel systems. On
- my really old 4-core system, this cuts a multi-target build from ~60 sec
- to ~30 sec. We eventually want to move all compile+link steps to this
- common dir anyways, so might as well move linking now for a nice speedup.
-
- We use noinst_PROGRAMS instead of bin_PROGRAMS because we're taking care
- of the install ourselves rather than letting automake process it.

- sim: build: add uninstall support
- This never worked before, but adding it to the common top-level dir
- is pretty easy to do now that we're unified.
-
- sim: build: move install steps to the top-level
- We still have to maintain custom install rules due to how we rename
- arch-specific files with an arch prefix in their name, but we can at
- least unify the logic in the common dir.
-
- sim: cris: move rvdummy linking to top-level
- This is only used by `make check`, so we can move it out of the
- default build too.
-
- sim: build: add SIM_HW_CFLAGS to top-level build too
- This matches what we do with targets already.
-
- sim: drop unused SIM_HARDWARE variable
- This hasn't been used since the refactor way back in commit
- f872d0d643968c1101bb8c07b252edd54f626da2 ("Only enable H/W
- on some mips targets."), so punt it.
-
- sim: adjust sim_hw options style
- We use uppercase for other variables, and are already turning it to
- uppercase in the arch-subdir.mk, so convert it in the configure step.
-
- sim: ppc: drop unused /dev/zero logic
- Nothing in the tree checks this option, or has checked for decades.
- The pre-cvs-import ChangeLog suggests this was added & removed back
- then, but can't be sure as that history doesn't exist in the VCS.
-
- sim: ppc: delete unused host bitsize settings
- Nothing checks this define anywhere, so drop all the logic. We don't
- want this to be a configure option in the first place as all such usage
- should be automatic & following proper types.
-
- sim: ppc: inline the sim-packages option
- This has only ever had a single option that's enabled by default.
- The objects it adds are pretty small and don't add overhead at
- runtime if it isn't used, so just enable it all the time to make
- the build code simpler.

- Powerpc fix for gdb.base/unwind-on-each-insn.exp
- The test disassembles function foo and searches for the line
- "End of assembler dump" to determing the last address in the function. The
- assumption is the last instruction will be given right before the line
- "End of assembler dump". This assumption fails on PowerPC.
-
- The PowerPC disassembly of the function foo looks like:
- Dump of assembler code for function foo:
- # => 0x00000000100006dc <+0>: std r31,-8(r1)
- # 0x00000000100006e0 <+4>: stdu r1,-48(r1)
- # 0x00000000100006e4 <+8>: mr r31,r1
- # 0x00000000100006e8 <+12>: nop
- # 0x00000000100006ec <+16>: addi r1,r31,48
- # 0x00000000100006f0 <+20>: ld r31,-8(r1)
- # 0x00000000100006f4 <+24>: blr
- # 0x00000000100006f8 <+28>: .long 0x0
- # 0x00000000100006fc <+32>: .long 0x0
- # 0x0000000010000700 <+36>: .long 0x1000180
- # End of assembler dump.
-
- The blr instruction is the last instruction in function foo. The lines
- with .long following the blr instruction need to be ignored.
-
- This patch adds a new condition to the gdb_test_multiple "disassemble foo"
- test to ignore the lines with the .long.
-
- The patch has been tested on PowerPC and Intel X86-64.

-
- Some people were seeing their builds failing with complaints about a

- of this issue in this commit:
-
- commit 2df82cd4b459fbc32120e0ad1ce19e26349506fe
- Date: Tue Nov 1 10:36:59 2022 +0000
-
- opcodes/arm: silence compiler warning about uninitialized variable use
-
- which did fix the build problems that the sourceware buildbot was
- hitting, however, an additional instance of the same problem was
- brought to my attention, and that is fixed in this commit.
-
- Where commit 2df82cd4b4 fixed the uninitialized variable problem in
- print_mve_unpredictable, this commit fixes the same problem in
- print_mve_undefined.
-
- As with the previous commit, I don't believe we could really ever get
- an uninitialized variable usage, based on the current usage of the
- function, so I have just initialized the reason variable to "??".

-
- sim: build: change AC_CHECK_LIB to AC_SEARCH_LIBS

- This gets funky though: when we run check in parallel, the output

- with -j1, the output object dir is the sim builddir itself.
-
- The old test would append argv[0] to find the file, while the new

- sim: erc32: link sis to run program
- The erc32 sim does a lot itself, including handling of the CLI. It
- used to provide a run-compatible interface in the pre-nrun days, but
- it was dropped when the old run interface was punted. Since the old
- commit 465fb143c87076b6416a8d0d5dd79bb016060fe3 ("sim: make nrun the
- default run program"), the erc32 run & sis programs have been the
- same, and erc32 hasn't provide a real run-compatible interface.
-
- Simplify this by linking the two programs via ln/cp instead of running
- the linking phase twice to produce the same result. If/when we fix up
- the erc32 port to have a proper run interface, it should be easy to
- split these back apart into real programs.
-
- Note: the interf.o reference in here is a bit of a misdirect. Since
- that object is placed into libsim.a, it's never been linked into the
- programs since the linker ignores objects that aren't referenced, and
- only gdb uses those symbols.

- macros after the last file is closed, the macros never end up "in scope"
- and so we can't print them. This has been submitted as a bug to Clang
- developers (https://github.com/llvm/llvm-project/issues/54506), and PR
- macros/29034 was opened for GDB to keep track of this.
-
- Seeing as there is no expected date for it to be fixed, add a workaround
- for all current versions of Clang. The workaround detects when
- the main file would be closed and if the producer is Clang, and turns
- that operation into a noop, so we keep a reference to the current_file
- as those macros are read.
-
- A test case was added to confirm the functionality, and the KFAIL for
- running gdb.base/macro-source-path when using clang.

- sim: move common flags to default AM_CPPFLAGS
- Since all host files we compile use these settings, move them out of
- libcommon.a and into the default AM_CPPFLAGS. This has the effect of
- dropping the custom per-target automake rules. Currently it saves us
- ~150 lines, but since it's about ~8 lines per object, the overhead
- will increase quite a bit as we merge more files into a single build.
-
- This also changes the object output names, so we have to tweak the
- rules that were pulling in the common objects when linking.

- x86: drop bogus Tbyte
- Prior to commit 1cb0ab18ad24 ("x86/Intel: restrict suffix derivation")
- the Tbyte modifier on the FLDT and FSTPT templates was pointless, as
- No_ldSuf would have prevented it being accepted. Due to the special
- nature of LONG_DOUBLE_MNEM_SUFFIX said commit, however, has led to these
- insns being accepted in Intel syntax mode even when "tbyte ptr" was
- present. Restore original behavior by dropping Tbyte there. (Note that
- these insns in principle should by marked AT&T syntax only, but since
- they haven't been so far we probably shouldn't change that.)
-
- x86: simplify expressions in update_imm()
- Comparing the sum of the relevant .imm<N> fields against a constant imo
- makes more obvious what is actually meant. It allows dropping of two
- static variables, with a 3rd drop requiring two more minor adjustments
- elsewhere, utilizing that "i" is zeroed first thing in md_assemble().
- This also increases the chances of the compiler doing the calculations
- all in registers.

- opcodes/arm: silence compiler warning about uninitialized variable use
- The earlier commit:

- commit 6576bffe6cbbb53c5756b2fccd2593ba69b74cdf
- Date: Thu Jul 7 13:43:45 2022 +0100
-
- opcodes/arm: add disassembler styling for arm
-
- was causing a compiler warning about a possible uninitialized variable
- usage within opcodes/arm-dis.c.
-
- The problem is in print_mve_unpredictable, and relates to the reason
- variable, which is set by a switch table.
-
- Currently the switch table does cover every valid value, though there
- is no default case. The variable switched on is passed in as an
- argument to the print_mve_unpredictable function.
-
- Looking at how print_mve_unpredictable is used, there is only one use,
- the second argument is the one that is used for the switch table,
- looking at how this argument is set, I don't believe it is possible
- for this argument to take an invalid value.
-
- So, I think the compiler warning is a false positive. As such, my
- proposed solution is to initialize the reason variable to the string
- "??", this will silence the warning, and the "??" string should never
- end up being printed.

-
- opcodes/arm: add disassembler styling for arm
- This commit adds disassembler styling for the ARM architecture.
-
- The ARM disassembler is driven by several instruction tables,
- e.g. cde_opcodes, coprocessor_opcodes, neon_opcodes, etc
-
- The type for elements in each table can vary, but they all have one
- thing in common, a 'const char *assembler' field. This field
- contains a string that describes the assembler syntax of the
- instruction.
-
- Embedded within that assembler syntax are various escape characters,
- prefixed with a '%'. Here's an example of a very simple instruction
- from the arm_opcodes table:
-
- "pld\t%a"
-
- The '%a' indicates a particular type of operand, the function
- print_insn_arm processes the arm_opcodes table, and includes a switch
- statement that handles the '%a' operand, and takes care of printing
- the correct value for that instruction operand.
-
- It is worth noting that there are many print_* functions, each
- function handles a single *_opcodes table, and includes its own switch
- statement for operand handling. As a result, every *_opcodes table
- uses a different mapping for the operand escape sequences. This means
- that '%a' might print an address for one *_opcodes table, but in a
- different *_opcodes table '%a' might print a register operand.
-
- Notice as well that in our example above, the instruction mnemonic
- 'pld' is embedded within the assembler string. Some instructions also
- include comments within the assembler string, for example, also from
- the arm_opcodes table:
-
- "nop\t\t\t@ (mov r0, r0)"
-
- here, everything after the '@' is a comment that is displayed at the
- end of the instruction disassembly.
-
- The next complexity is that the meaning of some escape sequences is
- not necessarily fixed. Consider these two examples from arm_opcodes:
-
- "ldrex%c\tr%12-15d, [%16-19R]"
- "setpan\t#%9-9d"
-
- Here, the '%d' escape is used with a bitfield modifier, '%12-15d' in
- the first instruction, and '%9-9d' in the second instruction, but,
- both of these are the '%d' escape.
-
- However, in the first instruction, the '%d' is used to print a
- register number, notice the 'r' immediately before the '%d'. In the
- second instruction the '%d' is used to print an immediate, notice the
- '#' just before the '%d'.
-
- We have two problems here, first, the '%d' needs to know if it should
- use register style or immediate style, and secondly, the 'r' and '#'
- characters also need to be styled appropriately.
-
- The final thing we must consider is that some escape codes result in
- more than just a single operand being printed, for example, the '%q'
- operand as used in arm_opcodes ends up calling arm_decode_shift, which
- can print a register name, a shift type, and a shift amount, this
- could end up using register, sub-mnemonic, and immediate styles, as
- well as the text style for things like ',' between the different
- parts.
-
- I propose a three layer approach to adding styling:
-
- (1) Basic state machine:
-
- When we start printing an instruction we should maintain the idea
- of a 'base_style'. Every character from the assembler string will
- be printed using the base_style.
-
- The base_style will start as mnemonic, as each instruction starts
- with an instruction mnemonic. When we encounter the first '\t'
- character, the base_style will change to text. When we encounter
- the first '@' the base_style will change to comment_start.
-
- This simple state machine ensures that for simple instructions the
- basic parts, except for the operands themselves, will be printed in
- the correct style.
-
- (2) Simple operand styling:
-
- For operands that only have a single meaning, or which expand to
- multiple parts, all of which have a consistent meaning, then I
- will simply update the operand printing code to print the operand
- with the correct style. This will cover a large number of the
- operands, and is the most consistent with how styling has been
- added to previous architectures.
-
- (3) New styling syntax in assembler strings:
-
- For cases like the '%d' that I describe above, I propose adding a
- new extension to the assembler syntax. This extension will allow
- me to temporarily change the base_style. Operands like '%d', will
- then print using the base_style rather than using a fixed style.
-
- Here are the two examples from above that use '%d', updated with
- the new syntax extension:
-
- "ldrex%c\t%{R:r%12-15d%}, [%16-19R]"
- "setpan\t%{I:#%9-9d%}"
-
- The syntax has the general form '%{X:....%}' where the 'X'
- character changes to indicate a different style. In the first
- instruction I use '%{R:...%}' to change base_style to the register
- style, and in the second '%{I:...%}' changes base_style to
- immediate style.
-
- Notice that the 'r' and '#' characters are included within the new
- style group, this ensures that these characters are printed with
- the correct style rather than as text.
-
- The function decode_base_style maps from character to style. I've
- included a character for each style for completeness, though only
- a small number of styles are currently used.
-
- I have updated arm-dis.c to the above scheme, and checked all of the
- tests in gas/testsuite/gas/arm/, and the styling looks reasonable.
-
- There are no regressions on the ARM gas/binutils/ld tests that I can
- see, so I don't believe I've changed the output layout at all. There
- were two binutils tests for which I needed to force the disassembler
- styling off.
-
- I can't guarantee that I've not missed some untested corners of the
- disassembler, or that I might have just missed some incorrectly styled
- output when reviewing the test results, but I don't believe I've
- introduced any changes that could break the disassembler - the worst
- should be some aspect is not styled correctly.

-
- opcodes/arm: use '@' consistently for the comment character
- Looking at the ARM disassembler output, every comment seems to start
- with a ';' character, so I assumed this was the correct character to
- start an assembler comment.
-
- I then spotted a couple of places where there was no ';', but instead,
- just a '@' character. I thought that this was a case of a missing
- ';', and proposed a patch to add the missing ';' characters.
-
- Turns out I was wrong, '@' is actually the ARM assembler comment
- character, while ';' is the statement separator. Thus this:
-
- nop ;@ comment
-
- is two statements, the first is the 'nop' instruction, while the
- second contains no instructions, just the '@ comment' comment text.
-
- This:
-
- nop @ comment
-
- is a single 'nop' instruction followed by a comment. And finally,
- this:
-
- nop ; comment
-
- is two statements, the first contains the 'nop' instruction, while the
- second contains the instruction 'comment', which obviously isn't
- actually an instruction at all.
-
- Why this matters is that, in the next commit, I would like to add
- libopcodes syntax styling support for ARM.
-
- The question then is how should the disassembler style the three cases
- above?
-
- As '@' is the actual comment start character then clearly the '@' and
- anything after it can be styled as a comment. But what about ';' in
- the second example? Style as text? Style as a comment?
-
- And the third example is even harder, what about the 'comment' text?
- Style as an instruction mnemonic? Style as text? Style as a comment?
-
- I think the only sensible answer is to move the disassembler to use
- '@' consistently as its comment character, and remove all the uses of
- ';'.
-
- Then, in the next commit, it's obvious what to do.
-
- There's obviously a *lot* of tests that get updated by this commit,
- the only actual code changes are in opcodes/arm-dis.c.

-
- Remove REPARSE condition to force hardware resource checking when updating watchpoints
- Currently the resource checking is done if REPARSE is true. The hardware
- watchpoint resource checking in update_watchpoint needs to be redone on
- each call to function update_watchpoints as the value chain may have
- changed. The number of hardware registers needed for a watchpoint can
- change if the variable being watched changes. This situation occurs in
- this test when watching variable **global_ptr_ptr. Initially when the
- watch command is issued, only two addresses need to be watched as
- **global_ptr_ptr has not yet been initialized. Once the value of
- **global_ptr_ptr is initialized the locations to be tracked increase to
- three addresses. However, update_watchpoints is not called again with
- REPARSE set to 1 to force the resource checking to be redone. When the
- test is run on Power 10, an internal gdb error occurs when the PowerPC
- routine tries to setup the three hardware watchpoint address since the hw
- only has two hardware watchpoint registers. The error occurs because the
- resource checking was not redone in update_watchpoints after
- **global_ptr_ptr changed.
-
- The following descibes the situation in detail that occurs on Power 10 with
- gdb running on the binary for gdb.base/watchpoint.c.
-
- 1 break func4
- 2 run
- 3 watch *global_ptr
- 4 next execute source code: buf[0] = 3;
- 5 next execute source code: global_ptr = buf;
- 6 next execute source code: buf[0] = 7;
- 7 delete 2 (delete watch *global_ptr)
- 8 watch **global_ptr_ptr
- 9 next execute source code: buf[1] = 5;
- 10 next global_ptr_ptr = &global_ptr;
- 11 next buf[0] = 9;
-
- In step 8, the the watch **global_ptr_prt command calls update_watchpoint
- in breakpoint.c with REPARSE set to 1. The function update_watchpoint
- calls can_use_hardware_watchpoint to see if there are enough
- resources available to add the watchpoint since REPARSE is set to 1. At
- this point, **global_ptr_ptr has not been initialized so only two addresses
- are watched. The val_chain contains the address for **global_ptr_ptr and 0
- since **global_ptr_ptr has not been initialized. The update_watchpoint
- updates the breakpoint list as follows:
-
- breakpoint 0
- loc 0: b->address = 0x100009c0
- breakpoint 1
- loc 1: b->address = 0x7ffff7f838a0
- breakpoint 2
- loc 2: b->address = 0x7ffff7b7fc54
- breakpoint 3
- loc 3: b->address = 0x7ffff7a5788c
- breakpoint 4
- loc 4: b->address = 0x0 <-- location pointed to by global_ptr_ptr
- loc 5: b->address = 0x100200b8 <-- global_ptr_ptr watchpoint
- breakpoint 5
- loc 6: b->address = 0x7ffff7b7fc54
-
- In step 10, the next command executes the source code
- global_ptr_ptr = &global_ptr. This changes the set of locations to be
- watched for the watchpoint **global_ptr_prt. The list of addresses for the
- breakpoint consist of the address for global_ptr_prt, global_ptr and buf.
- The breakpoint list gets updated by update_watchpoint as follows:
-
- breakpoint 0
- loc 0: b->address = 0x100009c0
- breakpoint 1
- loc 1: b->address = 0x7ffff7f838a0
- breakpoint 2
- loc 2: b->address = 0x7ffff7b7fc54
- breakpoint 3
- loc 3: b->address = 0x7ffff7a5788c
- breakpoint 4
- loc 4: b->address = 0x10020050 buf
- loc 5: b->address = 0x100200b0 watch *global_ptr
- loc 6: b->address = 0x100200b8 watch **global_ptr_ptr
- breakpoint 5
- loc 7: b->address = 0x7ffff7b7fc54
- breakpoint 6
-
- However, the hardware resource checking was not redone because
- update_breakpoint was called with REPARSE equal to 0.
-
- Step 11, execute the third next command. The function
- ppc_linux_nat_target::low_prepare_to_resume() attempts a ptrace
- call to setup each of the three address for breakpoint 4. The slot
- value returned for the third ptrace call is -1 indicating an error
- because there are only two hardware watchpoint registers available on
- Power 10.
-
- This patch removes just the statement "if (reparse)" in function
- update_watchpoint to force the resources to be rechecked on every call to
- the function. This ensures that any changes to the val_chain resulting
- in needing more resources then available will be caught.
-
- The patch has been tested on Power 8, Power 10 and X86-64. Note the patch
- has no effect on Power 9 since hardware watchpoint support is disabled on
- that processor.

- # bash$ make check RUNTESTFLAGS="--target_board=remote-stdio-gdbserver \
- # REMOTE_USERNAME=... REMOTE_HOSTNAME=... REMOTE_PORTNUM=... \
- # [REMOTE_TMPDIR=${remote_dir}] [GDBSERVER=${remote_gdbserver}]"

- but when adding REMOTE_PORTNUM=22, I run into:
- ...
- Running stop-reply-no-thread-multi.exp ...
- ERROR: tcl error sourcing stop-reply-no-thread-multi.exp.

- sim, sim/{m32c,ppc,rl78}: Use getopt_long
- Because of a Libiberty hack, getopt on GNU libc (2.25 or earlier) is
- currently unusable on sim, causing a regression on CentOS 7.
-
- This is caused as follows:
-
- 1. If HAVE_DECL_GETOPT is defined (getopt declaration with known prototype
- is detected while configuration), a declaration of getopt in
- "include/getopt.h" is suppressed.
- The author started to define HAVE_DECL_GETOPT in sim with the commit
- 340aa4f6872c ("sim: Check known getopt definition existence").
- 2. GNU libc (2.25 or earlier)'s <unistd.h> includes <getopt.h> with a
- special purpose macro defined to declare only getopt function but due
- to include path (not tested while configuration), it causes <unistd.h>
- to include Libiberty's "include/getopt.h".
- 3. If both 1. and 2. are satisfied, despite that <unistd.h> tries to
- declare getopt by including <getopt.h>, "include/getopt.h" does not do
- so, causing getopt function undeclared.
-
- Getting rid of "include/getopt.h" (e.g. renaming this header file) is the
- best solution to avoid hacking but as a short-term solution, this commit
- replaces getopt with getopt_long under sim/.

- [gdb/testsuite] Fix silent timeouts in gdb.mi/mi-exec-run.exp with remote host
- I noticed that running test-case gdb.mi/mi-exec-run.exp with host board
- local-remote-host.exp takes about 44 seconds.
-
- I found two silent timeouts responsible for this.
-
- The first is in mi_gdb_exit, where we have:
- ...
- if { [is_remote host] && [board_info host exists fileid] } {
- send_gdb "999-gdb-exit\n"
- gdb_expect 10 {
- -re "y or n" {
- send_gdb "y\n"
- exp_continue
- }
- -re "Undefined command.*$gdb_prompt $" {
- send_gdb "quit\n"
- exp_continue
- }
- -re "DOSEXIT code" { }
- }
- }
- ...
- so in gdb.log we see:
- ...
- 999-gdb-exit^M
- 999^exit^M
- =thread-exited,id="1",group-id="i1"^M
- =thread-group-exited,id="i1"^M
- ...
- after which expect just waits for the timeout.
-
- Fix this by adding a gdb_expect clause to parse the exit:
- ...
- -re "\r\n999\\^exit\r\n" { }
- ...
-
- Note that we're not parsing the thread-exited/thread-group-exited messages, because
- they may not be present:
- ...
- $ gdb -i=mi
- =thread-group-added,id="i1"
- (gdb)
- 999-gdb-exit
- 999^exit
- $
- ...
-
- After fixing that, we have:
- ...
- (gdb) ^M
- saw mi error
- PASS: gdb.mi/mi-exec-run.exp: inferior-tty=separate: mi=separate: \
- force-fail=1: run failure detected
- quit^M
- &"quit\n"^M
- ...
-
- What seems to be happening is that default_gdb_exit sends a cli interpreter
- quit command to an mi interpreter, after which again expect just waits for the
- timeout.
-
- Fix this by adding mi_gdb_exit to the end of the test-case, as in many other
- gdb.mi/*.exp test-cases.
-
- After these two fixes, the test-case takes about 4 seconds.
-
- Tested on x86_64-linux.

- [gdb/testsuite] Use remote_exec chmod instead of remote_spawn
- I build gdb using -O2, and ran the testsuite using taskset -c 0, and ran into:
- ...
- (gdb) PASS: gdb.server/connect-with-no-symbol-file.exp: sysroot=: \
- action=delete: setup: adjust sysroot
- builtin_spawn gdbserver --once localhost:2385 /connect-with-no-symbol-file^M

- localhost:2385: Connection timed out.^M
- (gdb) FAIL: gdb.server/connect-with-no-symbol-file.exp: sysroot=: \
- action=delete: connection to GDBserver succeeded
- ...
-
- The expected series of events is (skipping disconnect and detach as I don't
- think they're relevant to the problem):
- - enter scenario "permission"
- - cp $exec.bak $exec
- - gdbserver start with $exec
- - chmod 000 $exec
- - connect to gdbserver
- - enter scenario "delete"
- - cp $exec.bak $exec
- - gdbserver start with $exec
- - delete $exec
- - connect to gdbserver
-
- The problem is that the chmod is executed using remote_spawn:
- ...
- } elseif { $action == "permission" } {
- remote_spawn target "chmod 000 $target_exec"
- }
- ...
- without waiting on the resulting spawn id, so we're not sure when the
- chmod will have effect.
-
- The FAIL we're seeing above is explained by the chmod having effect during the
- delete scenario, after the "cp $exec.bak $exec" and before the "gdbserver
- start with $exec".
-
- Fix this by using remote_exec instead.
-
- Likewise, fix a similar case in gdb.mi/mi-exec-run.exp.

- gdb/testsuite: fix gdb.guile/scm-parameter.exp "wrong type argument" test pattern for Guile >= 2.2
- Since commit 90319cefe3 ("GDB/Guile: Don't assert that an integer value
- is boolean"), I see:
-
- FAIL: gdb.guile/scm-parameter.exp: kind=PARAM_ZINTEGER: test-PARAM_ZINTEGER-param: guile (set-parameter-value! test-PARAM_ZINTEGER-param #:unlimited)
- FAIL: gdb.guile/scm-parameter.exp: kind=PARAM_ZUINTEGER: test-PARAM_ZUINTEGER-param: guile (set-parameter-value! test-PARAM_ZUINTEGER-param #:unlimited)
-
- This comes from the fact that GDB outputs this:
-
- ERROR: In procedure set-parameter-value!:
- In procedure gdbscm_set_parameter_value_x: Wrong type argument in position 2 (expecting integer): #:unlimited
- Error while executing Scheme code.
-
- while the test expects an additional "ERROR:" on the second line,
- something like this:
-
- ERROR: In procedure set-parameter-value!:
- ERROR: In procedure gdbscm_set_parameter_value_x: Wrong type argument in position 2 (expecting integer): #:unlimited
- Error while executing Scheme code.
-
- Guile 2.0 outputs the `ERROR:` on the second line, while later versions
- do not. Change the pattern to accept both outputs. This is similar to
- commit 6bbe1a929c6 ("[gdb/testsuite] Fix gdb.guile/scm-breakpoint.exp

- gdb/arm: Fix M-profile EXC_RETURN
- Arm v8-M Architecture Reference Manual,
- D1.2.95 EXC_RETURN, Exception Return Payload
- describes ES bit:
-
- "ES, bit [0]
- Exception Secure. The security domain the exception was taken to.
- The possible values of this bit are:
- 0 Non-secure.
- 1 Secure"
-
- arm-tdep.c:3443, arm_m_exception_cache () function tests this bit:
-
- exception_domain_is_secure = (bit (lr, 0) == 0);
-
- The test is negated!
-
- Later on line 3553, the condition evaluates if an additional state
- context is stacked:
-
- /* With the Security extension, the hardware saves R4..R11 too. */
- if (tdep->have_sec_ext && secure_stack_used
- && (!default_callee_register_stacking || exception_domain_is_secure))
-
- RM, B3.19 Exception entry, context stacking
- reads:
- RPLHM "In a PE with the Security Extension, on taking an exception,
- the PE hardware:
- ...
- 2. If exception entry requires a transition from Secure state to
- Non-secure state, the PE hardware extends the stack frame and also
- saves additional state context."
-
- So we should test for !exception_domain_is_secure instead of non-negated
- value!
- These two bugs compensate each other so unstacking works correctly.
-
- But another test of exception_domain_is_secure (negated due to the
- first bug) prevents arm_unwind_secure_frames to work as expected:
-
- /* Unwinding from non-secure to secure can trip security
- measures. In order to avoid the debugger being
- intrusive, rely on the user to configure the requested
- mode. */
- if (secure_stack_used && !exception_domain_is_secure
- && !arm_unwind_secure_frames)
-

- gdb/arm: Terminate frame unwinding in M-profile lockup
- In the lockup state the PC value of the the outer frame is irreversibly
- lost. The other registers are intact so LR likely contains
- PC of some frame next to the outer one, but we cannot analyze
- the nearest outer frame without knowing its PC
- therefore we do not know SP fixup for this frame.
-
- The frame unwinder possibly gets mad due to the wrong SP value.
- To prevent problems terminate unwinding if PC contains the magic
- value of the lockup state.
-
- Example session wihtout this change,
- Cortex-M33 CPU in lockup, gdb 13.0.50.20221016-git:
- ----------------
- (gdb) c
- Continuing.
-
- Program received signal SIGINT, Interrupt.

- #2 0x2002ffd8 in ?? ()
- Backtrace stopped: previous frame identical to this frame (corrupt stack?)
- (gdb)
- ----------------
- The frame #1 is at correct PC taken from LR, #2 is a total nonsense.
-
- With the change:
- ----------------
- (gdb) c
- Continuing.

- som.c reloc sanity checking
- This patch checks that relocations emitted in som_write_fixups have

- size field, which isn't used otherwise by the som backend. Note that
- the sizes used are not exactly those in the old sizing switch
- statement deleted from som_write_fixups, but all relocs handled by the
- main switch statement there get the same size. Most unhandled relocs
- get a zero size (exceptions being R_RELOCATION, R_SPACE_REF,
- R_MILLI_REL, R_BREAKPOINT which all involve writing one word according

- x86-64: Use only one default max-page-size
- On x86-64 the default ELF_MAXPAGESIZE depends on a configure
- option (--disable-separate-code). Since 9833b775
- ("PR28824, relro security issues") we use max-page-size for relro
- alignment (with a short interval, from 31b4d3a ("PR28824, relro
- security issues, x86 keep COMMONPAGESIZE relro") to its revert
- a1faa5ea, where x86-64 only used COMMONPAGESIZE as relro alignment
- target).
-
- But that means that a linker configured with --disable-separate-code
- behaves different from one configured with --enable-separate-code
- (the default), _even if using "-z {no,}separate-code" option to use
- the non-configured behaviour_ . In particular it means that when
- configuring with --disable-separate-code the linker will produce
- binaries aligned to 2MB pages on disk, and hence generate 2MB
- executables for a hello world (and even 6MB when linked with
- "-z separate-code").
-
- Generally we can't have constants that ultimately land in static
- variables be depending on configure options if those only influence
- behaviour that is overridable by command line options.
-
- So, do away with that, make the default MAXPAGESIZE be 4k (as is default
- for most x86-64 configs anyway, as most people won't configure with
- --disable-separate-code). If people need more they can use the
- "-z max-page-size" (with would have been required right now for a
- default configure binutils).

- gdb/testsuite: make sure to consume the prompt in gdb.base/unwind-on-each-insn.exp

- $ taskset -c 1 make check TESTS="gdb.base/unwind-on-each-insn.exp" RUNTESTFLAGS="--target_board=native-gdbserver"
-
- or more simply:
-
- $ make check-read1 TESTS="gdb.base/unwind-on-each-insn.exp"
-
- The problem is that the gdb_test_multiple call that grabs the frame id
- from "maint print frame-id" does not consume the prompt. Well, it does
- sometimes due to the trailing .*, but not always. If the prompt is not
- consumed, the tests that follow get confused:
-
- FAIL: gdb.base/unwind-on-each-insn.exp: gdb_breakpoint: set breakpoint at *foo
- FAIL: gdb.base/unwind-on-each-insn.exp: disassemble foo
- FAIL: gdb.base/unwind-on-each-insn.exp: get $sp and frame base in foo: get hexadecimal valueof "$sp"
- ... many more ...
-
- Use -wrap to make gdb_test_multiple consume the prompt.
-
- While at it, remove the bit that consumes the command name and do
- exp_continue, it's not really necessary. And for consistency, do the
- same changes to the gdb_test_multiple that consumes the stack address,
- although that one was fine, it did consume the prompt explicitly.

-
- Likewise for .s files, and gdb/testsuite/lib/my-syscalls.S.
-
- The idiom for arm seems to be to use %progbits instead, see commit 9a5911c08be

-
- RISC-V: Improve link time complexity.
- The riscv port does deletion and symbol table update for each relocation
- while relaxing, so we are moving section bytes and scanning symbol table once
- for each relocation. Compared to microblaze port, they record the relaxation
- changes into a table, then do the deletion and symbol table update once per
- section, rather than per relocation. Therefore, they should have better link
- time complexity than us.
-
- To improve the link time complexity, this patch try to make the deletion in
- linear time. Compared to record the relaxation changes into a table, we
- replace the unused relocation with R_RISCV_DELETE for the deleted bytes, and
- then resolve them at the end of the section. Assuming the number of
- R_RISCV_DELETE is m, and the number of symbols is n, the total link complexity
- should be O(m) for moving section bytes, and O(m*n^2) for symbol table update.
- If we record the relaxation changes into the table, and then sort the symbol
- table by values, then probably can reduce the time complexity to O(m*n*log(n))
- for updating symbol table, but it doesn't seem worth it for now.

- sim/lm32: fix some missing function declaration warnings
- In the lm32 simulator, I was seeing some warnings about missing
- function declarations.
-
- The lm32 simulator has a weird header structure, in order to pull in
- the full cpu.h header we need to define WANT_CPU_LM32BF. This is done
- in some files, but not in others. Critically, it's not done in some
- files that then use functions declared in cpu.h
-
- In this commit I added the missing #define so that the full cpu.h can
- be included.
-
- After doing this there are still a few functions that are used
- undeclared, these functions appear to be missing any declarations at
- all, so I've added some to cpu.h.
-
- With this done all the warnings when compiling lm32 are resolved for
- both gcc and clang, so I've removed the SIM_WERROR_CFLAGS line from
- Makefile.in, this allows lm32 to build with -Werror.

- with a comment and an empty statement.

- sim/ppc: fix for operator precedence warning from clang
- In the ppc simulator, clang was warning about some code like this:
-
- busy_ptr->nr_writebacks = 1 + (PPC_ONE_BIT_SET_P(out_vmask)) ? 1 : 2;
-
- The warning was:
-
- operator '?:' has lower precedence than '+'; '+' will be evaluated first
-
- I suspect that this is not the original authors intention.
- PPC_ONE_BIT_SET_P is going to be 0 or 1, so if we evaluate the '+'
- first, the condition will always be non-zero, so true. The whole
- expression could then be simplified to just '1', which doesn't make
- much sense.
-
- I suspect the answer the author was expecting was either 2 or 3. Why
- they didn't just write:
-
- busy_ptr->nr_writebacks = (PPC_ONE_BIT_SET_P(out_vmask)) ? 2 : 3;
-
- I have no clue, however, to keep the structure of the code unchanged,
- I've updated things to:
-
- busy_ptr->nr_writebacks = 1 + (PPC_ONE_BIT_SET_P (out_vmask) ? 1 : 2);
-
- which silences the warning from clang, and is, I am guessing, what the
- original author intended.

- sim/ppc: initialize a memory buffer in all cases
- In the ppc simulator's do_fstat function, which provides the fstat
- call for the simulator, if the fstat is going to fail then we
- currently write an uninitialized buffer into the simulated target.
-
- In theory, I think this is fine, we also write the error status into
- the simulated target, so, given that the fstat has failed, the target
- shouldn't be relying on the buffer contents.
-
- However, writing an uninitialized buffer means we might leak simulator
- private data into the simulated target, which is probably a bad thing.
- Plus it probably makes life easier if something consistent, like all
- zeros, is written rather than random junk, which might look like a
- successful call (except for the error code).
-
- So, in this commit, I initialize the stat buffer to zero before
- it is potentially used. If the stat call is not made then the buffer
- will be left initialized as all zeros.

- Fix incorrect .gdb_index with new DWARF scanner
- PR symtab/29694 points out a regression caused by the new DWARF
- scanner when the cc-with-gdb-index target board is used.
-
- What happens here is that an older version of gdb will make an index
- describing the "A" type as:
-
- [737] A: 1 [global, type]
-
- whereas the new gdb says:
-
- [1008] A: 0 [global, type]
-
- Here the old one is correct because the A in CU 0 is just a
- declaration without a size:
-
- <1><45>: Abbrev Number: 10 (DW_TAG_structure_type)
- <46> DW_AT_name : A
- <48> DW_AT_declaration : 1
- <48> DW_AT_sibling : <0x6d>
-
- This patch fixes the problem by introducing the idea of a "type
- declaration". I think gdb still needs to recurse into these types,
- searching for methods, but by marking the type itself as a
- declaration, gdb can skip this type during lookups and when writing
- the index.

- Fix crash in value_print_array_elements
- A user noticed that gdb would crash when printing a packed array after

- occasionally useful to print things in C mode when working in a non-C
- language -- this lets you see under the hood a little bit.
-
- The bug here is that generic value printing does not handle packed
- arrays at all. This patch fixes the bug by introducing a new function
- to extract a value from a bit offset and width.
-
- The new function includes a hack to avoid problems with some existing
- test cases when using -fgnat-encodings=all. Cleaning up this code
- looked difficult, and since "all" is effectively deprecated, I thought
- it made sense to simply work around the problems.

- gdb/reverse: Fix stepping over recursive functions
- Currently, when using GDB to do reverse debugging, if we try to use the
- command "reverse next" to skip a recursive function, instead of skipping
- all of the recursive calls and stopping in the previous line, we stop at
- the second to last recursive call, and need to manually step backwards
- until we leave the first call. This is well documented in PR gdb/16678.
-
- This bug happens because when GDB notices that a reverse step has
- entered into a function, GDB will add a step_resume_breakpoint at the
- start of the function, then single step out of the prologue once that
- breakpoint is hit. The problem was happening because GDB wouldn't give
- that step_resume_breakpoint a frame-id, so the first time the breakpoint
- was hit, the inferior would be stopped. This is fixed by giving the
- current frame-id to the breakpoint.
-
- This commit also changes gdb.reverse/step-reverse.c to contain a
- recursive function and attempt to both, skip it altogether, and to skip
- the second call from inside the first call, as this setup broke a
- previous version of the patch.

- Change calculation of frame_id by amd64 epilogue unwinder
- When GDB is stopped at a ret instruction and no debug information is
- available for unwinding, GDB defaults to the amd64 epilogue unwinder, to
- be able to generate a decent backtrace. However, when calculating the
- frame id, the epilogue unwinder generates information as if the return
- instruction was the whole frame.
-
- This was an issue especially when attempting to reverse debug, as GDB
- would place a step_resume_breakpoint from the epilogue of a function if
- we were to attempt to skip that function, and this breakpoint should
- ideally have the current function's frame_id to avoid other problems
- such as PR record/16678.
-
- This commit changes the frame_id calculation for the amd64 epilogue,
- so that it is always the same as the dwarf2 unwinder's frame_id.
-
- It also adds a test to confirm that the frame_id will be the same,
- regardless of using the epilogue unwinder or not, thanks to Andrew
- Burgess.

- gdb/python: break more dependencies between gdbpy_initialize_* functions
- In a later commit in this series I will propose removing all of the
- explicit gdbpy_initialize_* calls from python.c and replace these
- calls with a more generic mechanism.
-
- One of the side effects of this generic mechanism is that the order in
- which the various Python sub-systems within GDB are initialized is no
- longer guaranteed.
-
- On the whole I don't think this matters, most of the sub-systems are
- independent of each other, though testing did reveal a few places
- where we did have dependencies, though I don't think those
- dependencies were explicitly documented in comment anywhere.
-
- This commit is similar to the previous one, and fixes the second
- dependency issue that I found.
-
- In this case the finish_breakpoint_object_type uses the
- breakpoint_object_type as its tp_base, this means that
- breakpoint_object_type must have been initialized with a call to
- PyType_Ready before finish_breakpoint_object_type can be initialized.
-
- Previously we depended on the ordering of calls to
- gdbpy_initialize_breakpoints and gdbpy_initialize_finishbreakpoints in
- python.c.
-
- After this commit a new function gdbpy_breakpoint_init_breakpoint_type
- exists, this function ensures that breakpoint_object_type has been
- initialized, and can be called from any gdbpy_initialize_* function.
-
- I feel that this change makes the dependency explicit, which I think
- is a good thing.
-
- There should be no user visible changes after this commit.

-
- This commit removes the first dependency issue, with this and the next
- commit, all of the implicit inter-sub-system dependencies will be
- replaced by explicit dependencies, which will allow me to, I think,
- clean up how the sub-systems are initialized.
-
- The dependency is around the py_insn_type. This type is setup in
- gdbpy_initialize_instruction and used in gdbpy_initialize_record.
- Rather than depend on the calls to these two functions being in a
- particular order, in this commit I propose adding a new function
- py_insn_get_insn_type. This function will take care of setting up the
- py_insn_type type and calling PyType_Ready. This helper function can
- be called from gdbpy_initialize_record and
- gdbpy_initialize_instruction, and the py_insn_type will be initialized
- just once.
-
- To me this is better, the dependency is now really obvious, but also,
- we no longer care in which order gdbpy_initialize_record and
- gdbpy_initialize_instruction are called.

- Test stepping within a runtime loader / dynamic linker
- See the remarks in rtld-step.exp for a description of what this
- test is about.
-
- This test case has been tested using gcc on the following x86-64 Linux
- distributions/releases:
-
- Fedora 28
- Fedora 32
- Fedora 33
- Fedora 34
- Fedora 35
- Fedora 36
- Fedora 37
- rawhide (f38)
- RHEL 9.1
- Ubuntu 22.04.1 LTS
-
- It's also been tested (and found to be working) with
- RUNTESTFLAGS="CC_FOR_TARGET=clang" on all of the above expect for
- Fedora 28. The (old) version of clang available on F28 did not
- accept the -static-pie option.
-
- I also tried to make this test work on FreeBSD 13.1. While I think I
- made significant progress, I was ultimately stymied by this message
- which occurs when attempting to run the main program which has been
- set to use the fake/pretend RTLD as the ELF interpreter:
-
- ELF interpreter /path/to/rtld-step-rtld not found, error 22
-
- I have left one of the flags (-static) in place which I believe
- to be needed for FreeBSD (though since I never got it to work, I
- don't know for sure.) I've also left some declarations needed
- for FreeBSD in rtld-step-rtld.c. They're currently disabled via
- a #if 0; you'll need to enable them if you want to try to make

- Allow debugging of runtime loader / dynamic linker
- At present, GDB does not allow for the debugging of the runtime loader
- and/or dynamic linker. Much of the time, this makes sense. An
- application programmer doesn't normally want to see symbol resolution
- code when stepping into a function that hasn't been resolved yet.
-
- But someone who wishes to debug the runtime loader / dynamic linker
- might place a breakpoint in that code and then wish to debug it
- as normal. At the moment, this is not possible. Attempting to step
- will cause GDB to internally step (and not stop) until code
- unrelated to the dynamic linker is reached.
-
- This commit makes a minor change to infrun.c which allows the dynamic
- loader / linker to be debugged in the case where a step, next, etc.
- is initiated from within that code.
-
- While developing this fix, I tried some approaches which weren't quite
- right. The GDB testusite definitely contains tests which FAIL when
- it's done incorrectly. (At one point, I saw 17 regressions!) This
- commit has been tested on x86-64 linux with no regressions.

- internal_error: remove need to pass __FILE__/__LINE__
- Currently, every internal_error call must be passed __FILE__/__LINE__
- explicitly, like:
-
- internal_error (__FILE__, __LINE__, "foo %d", var);
-
- The need to pass in explicit __FILE__/__LINE__ is there probably
- because the function predates widespread and portable variadic macros
- availability. We can use variadic macros nowadays, and in fact, we
- already use them in several places, including the related
- gdb_assert_not_reached.
-
- So this patch renames the internal_error function to something else,
- and then reimplements internal_error as a variadic macro that expands
- __FILE__/__LINE__ itself.
-
- The result is that we now should call internal_error like so:
-
- internal_error ("foo %d", var);
-
- Likewise for internal_warning.
-
- The patch adjusts all calls sites. 99% of the adjustments were done
- with a perl/sed script.
-
- The non-mechanical changes are in gdbsupport/errors.h,
- gdbsupport/gdb_assert.h, and gdb/gdbarch.py.

- The device_error function always ends up calling the error function,

-
- Doing this resolves a few warnings from hw_ide.c about possibly

- 232 | ENGINE_FN *engine_fns[MAX_NR_PROCESSORS];
- | ^~~~~~~~~~
-
- This is a false positive - we over allocate engine_fn, and then only
- initialize the nr_cpus entries which we will later go on to use.
-
- However, we can easily silence this warning by initializing the unused
- entries in engine_fns to NULL, this might also help if anyone ever
- looks at engine_fns in a debugger, it should now be obvious which
- entries are in use, and which are not.

- With this change the warning is gone.

- gdb/testsuite: avoid temporary file in gdb/testsuite (unittest.exp)
- I spotted that the gdb.gdb/unittest.exp script causes a temporary file
- inserters_extractors-2.txt to be created in build/gdb/testsuite/
- instead of in build/gdb/testsuite/output/gdb.gdb/unittest/.
-
- This is because some of the 'maint selftest' tests create temporary
- files in GDB's current directory, specifically, the two source files:
-
- gdb/unittests/basic_string_view/inserters/wchar_t/2.cc
- gdb/unittests/basic_string_view/inserters/char/2.cc
-
- both create a temporary file called inserters_extractors-2.txt, though
- we only run the second of these as part of GDB's selftests.
-
- I initially proposed just using GDB's 'cd' command in unittest.exp to
- switch to the test output directory before running the selftests,
- however, Pedro pointed out that there was a risk here that, if GDB
- crashed during shutdown, the generated core file would be left in the
- test output directory rather than in the testsuite directory. As a
- result, our clever core file spotting logic would fail to spot the
- core file and alert the user.
-
- Instead, I propose this slightly more involved solution. I've added a
- new with_gdb_cwd directory proc, used like this:
-
- with_gdb_cwd $directory {
- # Tests here...
- }
-
- The new proc temporarily switches to $directory and then runs the
- tests within the block. After running the tests the previous current
- working directory is restored.
-
- Additionally, after switching back to the previous cwd, we check that
- GDB is still responsive. This means that if GDB crashed immediately
- prior to restoring the previous directory, and left the core file in
- the wrong place, then the responsiveness check will fail, and a FAIL
- will be emitted, this should be enough to alert the user that
- something has gone wrong.
-
- With this commit in place the unittest.exp script now leaves its
- temporary file in the test output directory.

- gdb/testsuite: avoid creating files in gdb/testsuite directory
- I spotted that the test gdb.dwarf2/dw2-using-debug-str.exp was
- creating an output file called debug_str_section in the root
- build/gdb/testsuite directory instead of using the
- build/gdb/testsuite/output/gdb.dwarf2/dw2-using-debug-str/ directory.
-
- This appears to be caused by a missing '$' character. We setup a
- variable debug_str_section which contains a path within the output
- directory, but then when we build the objcopy command we use
- 'debug_str_section' without a '$' prefix, as a result, we create the
- debug_str_section file.
-
- This commit adds the missing '$', the file is now created in the

-
- To catch these, change the assert in reggroups::add to check for

- by the duplicate name check.

- Update tests to use skip_hw_watchpoint_tests to test for HW watchpoint support.
- The hardware watchpoint check has been updated in a couple of recent
- patches. This patch updates the hardware watchpoint test in the remaining
- gdb tests.
-
- The issue is the PowerPC processors support hardware watchpoints with the
- exception of Power 9. The hardware watchpoint support is disabled on
- Power 9. The test skip_hw_watchpoint_tests must be used to correctly
- determine if the PowerPC processor supports hardware watchpoints.
-
- This patch fixes 6 test failures in test gdb.threads/watchpoint-fork.exp.
-
- Test gdb.base/watch-vfork.exp runs with can-use-hw-watchpoints set to
- true and false. When the test is run with can-use-hw-watchpoints set to
- true, gdb just falls back to using software watchpoints. The
- patch reduces the number of expected passes by 2 since because it now
- only runs once with can-use-hw-watchpoints set to false.
-
- Test gdb.mi/mi-watch.exp runs the test with argument hw and sw. If the
- argument is hw and hardware watchpoints are not supported the test exits.
- The number of expected passes is cut in half with the patch as it now only
- runs the test using software breakpoints. Previously the pass to use
- hardware watchpoints was not skipped and the test actually ran using
- software watchpoints.
-
- The following tests run the same with and without the patch. The tests
- are supposed to execute the gdb command "set can-use-hw-watchpoints 0" if
- the processor does not support hardware bwatchpoints. However the command
- was not being executed and gdb was falling back to using software
- watchpoints since the Power 9 watchpoint resource check fails. With the
- patch, the tests now execute the command and the test runs using software
- watchpoints as it did previously. The tests are:
-
- gdb.base/commands.exp
- gdb.base/cond-eval-mode.exp
- gdb.base/display.exp
- gdb.base/gdb11531.exp
- gdb.base/recurse.exp

- gdb.base/watch-cond-infcall.exp
- gdb.base/watch-cond.exp
- gdb.base/watchpoint-solib.exp
- gdb.base/watchpoints.exp
-
- The following two tests are not supported on the Power 9 system used to
- test the changes. The patch does not change the tests results for these
- tests:
-
- gdb.python/py-breakpoint.exp
- gdb.mi/mi-watch-nonstop.exp

- gdb, solib-svr4: support namespaces in DSO iteration
- When looking up names, GDB needs to stay within one linker namespace to
- find the correct instance in case the same name is provided in more than
- one namespace.
-
- Modify svr4_iterate_over_objfiles_in_search_order() to stay within the
- namespace of the current_objfile argument. If no current_objfile is
- provided (i.e. it is nullptr), iterate over objfiles in the initial
- namespace.
-
- For objfiles that do not have a corresponding so_list to provide the
- namespace, assume that the objfile was loaded into the initial namespace.
- This would cover the main executable objfile (which is indeed loaded into
- the initial namespace) as well as manually added symbol files.
-
- Expected fails:
-
- - gdb.base/non-lazy-array-index.exp: the expression parser may lookup
- global symbols, which may result in xfers to read auxv for determining
- the debug base as part of svr4_iterate_over_objfiles_in_search_order().
-
- - gdb.server/non-lazy-array-index.exp: symbol lookup may access the
- target to read AUXV in order to determine the debug base for SVR4
- linker namespaces.
-
- Known issues:
-
- - get_symbol_address() and get_msymbol_address() search objfiles for a
- 'better' match. This was introduced by
-
- 4b610737f02 Handle copy relocations
-
- to handle copy relocations but it now causes a wrong address to be
- read after symbol lookup actually cound the correct symbol. This can
- be seen, for example, with gdb.base/dlmopen.exp when compiled with
- clang.
-
- - gnu ifuncs are only looked up in the initial namespace.
-
- - lookup_minimal_symbol() and lookup_minimal_symbol_text() directly
- iterate over objfiles and are not aware of linker namespaces.

- gdb, python: use gdbarch_iterate_over_objfiles_in_search_order
- The implementation of gdb.lookup_objfile() iterates over all objfiles and
- compares their name or build id to the user-provided search string.
-
- This will cause problems when supporting linker namespaces as the first
- objfile in any namespace will be found. Instead, use
- gdbarch_iterate_over_objfiles_in_search_order to only consider the
- namespace of gdb.current_objfile() for the search, which defaults to the
- initial namespace when gdb.current_objfile() is None.

-
- gdb, compile: unlink objfile stored in module
- When cleaning up after a compile command, we iterate over all objfiles and
- unlink the first objfile with the same name as the one we compiled.
-
- Since we already store a pointer to that objfile in the module and use it
- to get the name we're comparing against, there's no reason to iterate, at
- all. We can simply use that objfile.

- This is because clang 15 warns for something like this:

-
- yynerrs is defined in yyparse and is there for actions to use. Since
- the actions in cp-name-parser.y don't use it, we get a warning. We see
- this problem on this particular .y file because it uses `%pure-parser`

- I initially fixed this by using
- DIAGNOSTIC_IGNORE_UNUSED_BUT_SET_VARIABLE (like in commit f7aa1a5acc5

- ld/testsuite: consistently add board_ldflags when linking with GCC
- Currently, the functions checking if the compiler is available or if a
- feature is available add both board_cflags and board_ldflags.
- However, functions running the tests only retrieve board_cflags. This
- can lead to unexpected errors when mandaratory flags are defined in
- board_ldflags and not board_cflags.
-
- ld/ChangeLog:
-
- * testsuite/ld-unique/unique.exp: Add board_ldflags when
- linking with GCC.
- * testsuite/lib/ld-lib.exp: Likewise.

- Allow explicit size specifier for predicate operand of {sq, uq, }{incp, decp}
- Omitting predicate size specifier in vector form of {sq, uq, }{decp, incp} is deprecated and will be prohibited in a future release of the aarch64,
- see https://developer.arm.com/documentation/ddi0602/2021-09/SVE-Instructions/DECP--vector---Decrement-vector-by-count-of-true-predicate-elements-.
-
- This allows explicit size specifier, e.g. `decp z0.h, p0.h`, for predicate operand of these SVE instructions.
- The existing behaviour of not requiring the specifier is preserved.
- And the disasembly is with the specifier with this patch.

- x86: properly decode EVEX.W for AVX512_4{FMAPS,VNNIW} insns
- These require EVEX.W=0. Use %XS to facilitate the checking, even if for
- the AVX512_4VNNIW ones this is kind of an abuse (as 's' there stands for
- "signed", not "single").
-
- While there also correct the 3rd operand for the AVX512_4VNNIW entries:
- Only the memory form is allowed (just like for AVX512_4FMAPS, where the
- correct type is already in use).

- can be re-used for AVX512-VNNI, at the same time fixing the lack of
- EVEX.W decoding.
-
- For the AVX-VNNI ones further make sure only VEX.66 forms are actually
- decoded.

- zlib-gabi to zstd woes
- So we had a zlib-gabi .debug_info section that increased in size with
- zstd, so much so that it was better to leave the section
- uncompressed. Things went horribly wrong when the section was read
- again later. The section was read again off disk using the
- uncompressed size. So you get the zlib section again with some
- garbage at the end. Fix that particular problem by setting the
- section flag SEC_IN_MEMORY. Any future read will get sec->contents.
-
- Also, if the section is to be left uncompressed, the input
- SHF_COMPRESSED flag needs to be reset otherwise objcopy will copy it
- to output.
-
- Finally, bfd_convert_section_contents needed a small update to handle
- zstd compressed sections, and I've deleted bfd_cache_section_contents.
-
- * bfd.c (bfd_convert_section_contents): Handle zstd.
- * compress.c (bfd_compress_section_contents): When section
- contents are uncompressed set SEC_IN_MEMORY flag,
- compress_status to COMRESS_SECTION_NONE, and clear
- SHF_COMPRESSED. Set SEC_IN_MEMORY for compressed contents.
- (bfd_get_full_section_contents): Don't check section size
- against file size when SEC_IN_MEMORY.
- (bfd_cache_section_contents): Delete function.

- [gdb/testsuite] Fix host board local-remote-host-notty.exp timeouts
- With test-case gdb.server/stop-reply-no-thread-multi.exp and host board
- local-remote-host-notty.exp we occasionally run into a silent out, due to
- getting:
- ...
- (gdb) kill^M
- (gdb) The program is not being run.^M
- ...
- instead of the expected:
- ...
- (gdb) kill^M
- The program is not being run.^M
- (gdb)
- ...
-
- Likewise, we occasionally run into a nonsilent timeout:
- ...
- (gdb) disconnect^M
- (gdb) You can't do that when your target is `exec'^M
- FAIL: gdb.server/stop-reply-no-thread.exp: to_disable=Tthread: t_nonstop=on: \
- disconnect (timeout)
- ...
-
- Typically, this results in the test-case taking more than two minutes to run.
-
- The problem can be reproduced using just:
- ...
- $ ssh -l $USER 127.0.0.1 gdb -q -ex kill
- ...
-
- Note that ssh by default uses -T which disables pseudo-tty allocation (as
- opposed to -t which forces pseudo-tty allocation):
- ...
- $ ssh -l $USER 127.0.0.1 -T tty
- not a tty
- $ ssh -l $USER 127.0.0.1 -t tty
- /dev/pts/5
- Connection to 127.0.0.1 closed.
- ...
- and according to https://stackoverflow.com/a/63241102 the behaviour we're
- seeing is specific to using '-T'.
-
- The related host board local-remote-host.exp does use '-t', and the only
- difference between the two boards mentioned is whether editing is on or off.
-
- Fix this by:
- - moving the content of local-remote-host-notty.exp into
- local-remote-host.exp
- - consequently, extending the copyright years in local-remote-host.exp
- - including local-remote-host.exp in local-remote-host-notty.exp
- (making local-remote-host-notty.exp use '-t')
- - adding -iex "set editing off" to GDBFLAGS in local-remote-host-notty.exp
-
- This results in the test-case taking just 6 seconds to run.

- [gdb/testsuite] Disable styling in host board local-remote-host.exp
- With test-case gdb.server/stop-reply-no-thread.exp and host board
- local-remote-host.exp, I run into:
- ...
- Breakpoint 1, ^[[33mmain^[[m () at ^[[32mstop-reply-no-thread.c^[[m:21^M

- (gdb) FAIL: gdb.server/stop-reply-no-thread.exp: to_disable=: t_nonstop=off: \
- continue to main
- ...
-
- The problem is that styling is enabled, and that is causing a regexp mismatch.
-
- With native, styling is disabled in default_gdb_init by doing
- 'setenv TERM "dumb"', but that only has effect because the build (where we
- execute runtest, and consequently the setenv) and the host (where we execute
- gdb) are the same. For this host board however, gdb executes on a remote
- host, and the setenv has no effect.
-
- We could try to make some generic way to set TERM on the host, but for the
- purposes of this test-case it seems sufficient to just add:
- ...
- set GDBFLAGS "${GDBFLAGS} -iex \"set style enabled off\""
- ...
- so let's go with that for now.

- e200 LSP support
- It has bothered me for a long time that we have disabled LSP (and SPE)
- tests. Also the LSP test comment indicating there is something wrong
- with get_powerpc_dialect. I don't think there is. Decoding of a VLE
- instruction depends on whether the processor is in VLE mode (some
- processors support both VLE and standard PPC) which we flag per
- section with SHF_PPC_VLE for decoding when disassembling.
-
- Background: Some versions of powerpc e200 have "Lightweight Signal
- Processing" support, examples being e200z215 and e200z425. As far as
- I can tell, LSP and SPE are mutually exclusive. This seems to be
- borne out by insn encoding, for example LSP "zvaddih" and SPE "evaddw"
- have the same encoding. So none of the processor descriptions in
- ppc_opts ought to have both PPC_OPCODE_LSP and PPC_OPCODE_SPE/2, if we
- want disassembly to work. I also could not find anything to suggest
- that the LSP insns are enabled only in VLE mode, which means the LSP
- insns should not be in vle_opcodes.
-
- Fix all this by moving the LSP insns to their own table, and add a new
- e200z2 cpu entry with LSP support, removing LSP from -me200z4 and from
- -mvle. (Yes, I know, as I said above some of the e200z4 processors
- have LSP. Others have SPE. It's hard to choose good options. Think
- of z2 as meaning earlier, z4 as later.) Also add -mlsp to allow

- produces PIE by default.
-
- The target board unix/-fno-PIE/-no-pie has a potential problem when compiling
- shared libs, because the multilib_flags will override the attempts of
- gdb_compile_shlib to compile with -fPIC. This is taken care of by running the
- body of gdb_compile_shlib wrapped in with_PIE_multilib_flags_filtered.
-
- The target board unix/-fPIE/-pie has a problem with nopie compilations. The
- current approach is to do the compilation hoping for the best, and if we find
- out that the resulting executable is PIE despite specifying nopie, we error
- out with the standard error message "nopie failed to prevent PIE executable".
-
- That however does not work for hard-coded assembly nopie test-cases, which will
- just noisily refuse to compile:
- ...
- ld: amd64-disp-step0.o: relocation R_X86_64_32S against `.text' can not be \
- used when making a PIE object; recompile with -fPIE^M
- ...
-
- Fix this in gdb_compile by filtering out the PIE settings in the target board
- multilib_flags when pie or nopie is specified.
-
- Tested on x86_64-linux.

- RISC-V: Imply 'Zicsr' from privileged extensions with CSRs
- 'H', 'Smstateen', 'Sscofpmf' and 'Sstc' are four privileged extensions with
- their CSR definitions and 'Smepmp' is a privileged extension with additional
- CSR bits.
-
- Volume II: Privileged Architecture of the RISC-V ISA Manual states that the
- privileged architecture requires the 'Zicsr' extension. However, current
- GNU Binutils has no direct way whether the program has dependency to the
- privileged architecture itself.
-
- As a workaround, we should add implications from privileged extensions that
- either add new CSRs, extend existing CSRs or depends on using CSRs.
-
- This commit adds such implications for existing privileged extensions that

- PowerPC, fix gdb.base/watchpoint.exp on Power 9
- Test gdb.base/watchpoint.exp generates 4 test errors on Power 9. The
- test uses the test [target_info exists gdb,no_hardware_watchpoints] to
- determine if the processor supports hardware watchpoints. The check
- only examines the processor type to determine if it supports hardware
- watchpoints.
-
- The PowerPC processors support hardware watchpoints with the
- exception of Power 9. The hardware watchpoint support is disabled on
- Power 9. The test skip_hw_watchpoint_tests must be used to correctly
- determine if the PowerPC processor supports hardware watchpoints.
-
- This patch replaces the [target_info exists gdb,no_hardware_watchpoints]
- with the skip_hw_watchpoint_tests_p check. With the patch, the test runs
- on Power 9 with hardware watchpoint force-disabled. The test runs on
- all other PowerPC processors with and without hardware watchpoints
- enabled.
-
- The patch has been tested on Power 9 to verify the test only runs with
- hardware breakpoints disabled. The patch has been tested on X86-64 with
- no regression failures. The test fails on Power 10 due to an internal GDB
- error due to resource management. The resource management issue will be
- addressed in another patch.

- [gdb/testsuite] Fix gdb.dwarf2/macro-source-path.exp with -m32
- With test-case gdb.dwarf2/macro-source-path.exp and target board unix/-m32, I
- run into:
- ...
- as: macro-source-path-gcc11-ld238-dw5-filename-641.o: \
- unsupported relocation type: 0x1^M
- ...
-
- The problem is that we have 64-bit dwarf so the debug_line offset in the
- .debug_macro section is an 8-byte entity, emitted using ".8byte":
- ...
- .section .debug_macro
- .Lcu_macros4:
- .2byte 5 /* version */
- .byte 3 /* flags */
- .8byte .LLlines3 /* debug_line offset */
- ...
- but the linker doesn't support 8-byte relocation types on a 32-bit architecture.
-
- This is similar to what was fixed in commit a5ac8e7fa3b
- ("[gdb/testsuite] Fix 64-bit dwarf test-cases with -m32") for for instance
- .debug_abbrev.

- FAIL: gdb.mi/mi-disassemble.exp: byte at 0x8048485 matches
- ...
- The test-case passes with native.
-
- With native we see in gdb.log that variable longest_insn_bytes is:
- ...
- Longest instruction at 0x0000000000400549 with bytes '48 8b 05 20 01 00 00'
- ...
- and variable split_bytes (added debug puts) ends up as:
- ...
- SPLIT_BYTES: 48 8b 05 20 01 00 00
- ...
-
- But with unix/-m32 we have longest_insn_byte:
- ...
- Longest instruction at 0x08048481 with bytes '8d 4c 24 04 '
- ...
- and split_bytes ends up as:
- ...
- SPLIT_BYTES: 8d 4c 24 04 {} {} {} {} {} {} {} {}
- ...
- so the trailing whitespace is translated by split to empty bytes, and the
- mismatch FAILs are generated for those.
-
- Fix this by stripping the whitespace, which makes us end up with a different
- and indeed longer insn:
- ...
- Longest instruction at 0x08048492 with bytes 'dd 05 98 85 04 08'

- sim/ppc: fixes for arguments to printf style functions
- After the recent series of fixes to mark more functions in the

- gdb: fix auxv caching
- There's a flaw in the interaction of the auxv caching and the fact that
- target_auxv_search allows reading auxv from an arbitrary target_ops
- (passed in as a parameter). This has consequences as explained in this
- thread:
-
- https://inbox.sourceware.org/gdb-patches/20220719144542.1478037-1-luis.machado@arm.com/
-
- In summary, when loading an AArch64 core file with MTE support by
- passing the executable and core file names directly to GDB, we see the
- MTE info:
-
- $ ./gdb -nx --data-directory=data-directory -q aarch64-mte-gcore aarch64-mte-gcore.core
- ...
- Program terminated with signal SIGSEGV, Segmentation fault
- Memory tag violation while accessing address 0x0000ffff8ef5e000
- Allocation tag 0x1
- Logical tag 0x0.
- #0 0x0000aaaade3d0b4c in ?? ()
- (gdb)
-
- But if we do it as two separate commands (file and core) we don't:
-
- $ ./gdb -nx --data-directory=data-directory -q -ex "file aarch64-mte-gcore" -ex "core aarch64-mte-gcore.core"
- ...
- Program terminated with signal SIGSEGV, Segmentation fault.
- #0 0x0000aaaade3d0b4c in ?? ()
- (gdb)
-
- The problem with the latter is that auxv data gets improperly cached
- between the two commands. When executing the file command, auxv gets
- first queried here, when loading the executable:

- Here, target_auxv_search is called on the inferior's target stack. The
- target stack only contains the exec target, so the query returns empty
- auxv data. This gets cached for that inferior in `auxv_inferior_data`.
-
- In its constructor (before it is pushed to the inferior's target stack),
- the core_target needs to identify the right target description from the
- core, and for that asks the gdbarch to read a target description from
- the core file. Because some implementations of
- gdbarch_core_read_description (such as AArch64's) need to read auxv data
- from the core in order to determine the right target description, the
- core_target passes a pointer to itself, allowing implementations to call
- target_auxv_search it. However, because we have previously cached
- (empty) auxv data for that inferior, target_auxv_search searched that
- cached (empty) auxv data, not auxv data read from the core. Remember
- that this data was obtained by reading auxv on the inferior's target
- stack, which only contained an exec target.
-
- The problem I see is that while target_auxv_search offers the
- flexibility of reading from an arbitrary (passed as an argument) target,
- the caching doesn't do the distinction of which target is being queried,
- and where the cached data came from. So, you could read auxv from a
- target A, it gets cached, then you try to read auxv from a target B, and
- it returns the cached data from target A. That sounds wrong. In our
- case, we expect to read different auxv data from the core target than
- what we have read from the target stack earlier, so it doesn't make
- sense to hit the cache in this case.
-
- To fix this, I propose splitting the code paths that read auxv data from
- an inferior's target stack and those that read from a passed-in target.
- The code path that reads from the target stack will keep caching,
- whereas the one that reads from a passed-in target won't. And since,
- searching in auxv data is independent from where this data came from,
- split the "read" part from the "search" part.
-
- From what I understand, auxv caching was introduced mostly to reduce
- latency on remote connections, when doing many queries. With the change
- I propose, only the queries done while constructing the core_target
- end up not using cached auxv data. This is fine, because there are just
- a handful of queries max, done at this point, and reading core files is
- local.
-
- The changes to auxv functions are:
-
- - Introduce 2 target_read_auxv functions. One reads from an explicit
- target_ops and doesn't do caching (to be used in
- gdbarch_core_read_description context). The other takes no argument,
- reads from the current inferior's target stack (it looks just like a
- standard target function wrapper) and does caching.
-
- The first target_read_auxv actually replaces get_auxv_inferior_data,
- since it became a trivial wrapper around it.
-
- - Change the existing target_auxv_search to not read auxv data from the
- target, but to accept it as a parameter (a gdb::byte_vector). This
- function doesn't care where the data came from, it just searches in
- it. It still needs to take a target_ops and gdbarch to know how to
- parse auxv entries.
-
- - Add a convenience target_auxv_search overload that reads auxv
- data from the inferior's target stack and searches in it. This
- overload is useful to replace the exist target_auxv_search calls that
- passed the `current_inferior ()->top_target ()` target and keep the
- call sites short.
-
- - Modify parse_auxv to accept a target_ops and gdbarch to use for
- parsing entries. Not strictly related to the rest of this change,
- but it seems like a good change in the context.
-
- Changes in architecture-specific files (tdep and nat):
-
- - In linux-tdep, linux_get_hwcap and linux_get_hwcap2 get split in two,
- similar to target_auxv_search. One version receives auxv data,
- target and arch as parameters. The other gets everything from the
- current inferior. The latter is for convenience, to avoid making
- call sites too ugly.
-
- - Call sites of linux_get_hwcap and linux_get_hwcap2 are adjusted to
- use either of the new versions. The call sites in
- gdbarch_core_read_description context explicitly read auxv data from
- the passed-in target and call the linux_get_hwcap{,2} function with
- parameters. Other call sites use the versions without parameters.
-
- - Same idea for arm_fbsd_read_description_auxv.
-
- - Call sites of target_auxv_search that passed
- `current_inferior ()->top_target ()` are changed to use the
- target_auxv_search overload that works in the current inferior.

- sim: Check known getopt definition existence
- Clang generates a warning if there is a function declaration/definition
- with zero arguments. Such declarations/definitions without a prototype (an
- argument list) are deprecated forms of indefinite arguments
- ("-Wdeprecated-non-prototype"). On the default configuration, it causes a
- build failure (unless "--disable-werror" is specified).
-
- include/getopt.h defines some getopt function definitions but one of them
- has a form "extern int getopt ();". If this form is selected in
- include/getopt.h, Clang generates a warning and the build fails by default.
-
- In really old environments, this getopt definition with no arguments is
- necessary (because the definition may change between environments).
- However, this definition is now a cause of problems on modern environments.
-
- A good news is, this definition is not always selected (e.g. if used by
- binutils/*.c). This is because configuration scripts of binutils, gas,
- gprof and ld tries to find known definition of getopt function is used and
- defines HAVE_DECL_GETOPT macro. If this macro is defined when getopt.h is
- included, a good form of getopt is used and Clang won't generate warnings.
-
- This commit adds a modified portion of ld/configure.ac to find the known
- getopt definition. If we could find one (and we *will* in most modern
- environments), we don't need to rely on the deprecated definition.

- [gdb/testsuite] Fix prompt parsing in capture_command_output
- I noticed in capture_command_output that the output of a single command is
- matched using two gdb_test_multiples:
- - the first one matching the echoed command and skipping an optional prefix,
- - the second one matching the output and the prompt.
-
- This is error-prone, because the first gdb_test_multiple has implicit
- clauses which may consume the prompt.
-
- The problem is easy to spot with an example. First consider:
- ...
- set output [capture_command_output "print 1" "\\\$1 = "]
- gdb_assert { [string equal $output "1"] }
- ...
- for which we get:
- ...
- PASS: [string equal $output "1"]
- ...
-
- If we change the prefix string to a no-match, say "1 = ", and update the
- output string match accordingly, we get instead:
- ...
- FAIL: capture_command_output for print 1
- FAIL: [string equal $output "\$1 = 1"]
- ...
-
- The first FAIL is produced by the first gdb_test_multiple, consuming the prompt.
-
- The second gdb_test_multiple then silently times out waiting for another prompt,
- after which the second FAIL is produced. Note that the timeout is silent
- because the gdb_test_multiple is called with an empty message argument.
-
- The second FAIL is because capture_command_output returns "", given that all
- the command output was consumed by the first gdb_test_multiple.
-
- Fix this by rewriting capture_command_output to use only a single
- gdb_test_multiple.
-
- Tested on x86_64-linux.

- the end of the buffer. If there's anything following the prompt, it
- won't match.
-
- The diff above adds a delay between sending the command and consuming
- the output, giving GDB more time to output the messages, giving a good
- chance that expect consumes them at the same time as the prompt.
-
- This is normally handled by using gdb_test_multiple and specifying a
- pattern that ends with "$gdb_prompt", but not a trailing $. I think
- this is common enough that it deserves its own gdb_test option.
- Therefore, add the -no-anchor-prompt option to gdb_test, and
- gdb_test_no_output for completeness. Use it in
- gdb.base/async-shell.exp.

- Fix a latent bug in print_wchar
- print_wchar keeps track of when escape sequences are emitted, to force
- an escape sequence if needed by a subsequent character. For example
- for the string concatenation "\0" "1", gdb will print "\000\061" --
- because printing "\0001" might be confusing.
-
- However, this code has two errors. First, this logic is not needed
- for octal escapes, because there is a length limit of 3 for octal
- escapes, and gdb always prints these with "%.3o". Second, though,
- this *is* needed for hex escapes, because those do not have a length
- limit.
-
- This patch fixes these problems and adds the appropriate tests.

- gdb: include the base address in in-memory bfd filenames
- The struct target_buffer (in gdb_bfd.c) is used to hold information
- about an in-memory BFD object created by GDB. For now this mechanism
- is used by GDB when loading information about JIT symfiles.
-
- This commit updates target_buffer (in gdb_bfd.c) to be more C++ like,
- and, at the same time, adds the base address of the symfile into the
- BFD filename.
-
- Right now, every in-memory BFD is given the filename "<in-memory>".
- This filename is visible in things like 'maint info symtabs' and
- 'maint info line-table'. If there are multiple in-memory BFD objects
- then it can be hard to match keep track if which BFD is which. This
- commit changes the name to be "<in-memory@ADDRESS>" where ADDRESS is
- replaced with the base address for where the in-memory symbol file was
- read from.
-
- As an example of how this is useful, here's the output of 'maint info
- jit' showing a single loaded JIT symfile:
-
- (gdb) maintenance info jit
- jit_code_entry address symfile address symfile size
- 0x00000000004056b0 0x0000000007000000 17320
-
- And here's part of the output from 'maint info symtabs':
-
- (gdb) maintenance info symtabs
- ...snip...
- { objfile <in-memory@0x7000000> ((struct objfile *) 0x5258250)
- { ((struct compunit_symtab *) 0x4f0afb0)
- debugformat DWARF 4
- producer GNU C17 9.3.1 20200408 (Red Hat 9.3.1-2) -mtune=generic -march=x86-64 -g -fno-stack-protector -fpic
- name jit-elf-solib.c

- gdb/frame: Add reinflation method for frame_info_ptr
- Currently, despite having a smart pointer for frame_infos, GDB may
- attempt to use an invalidated frame_info_ptr, which would cause internal
- errors to happen. One such example has been documented as PR
- python/28856, that happened when printing frame arguments calls an
- inferior function.
-
- To avoid failures, the smart wrapper was changed to also cache the frame
- id, so the pointer can be reinflated later. For this to work, the
- frame-id stuff had to be moved to their own .h file, which is included
- by frame-info.h.
-
- Frame_id caching is done explicitly using the prepare_reinflate method.
- Caching is done manually so that only the pointers that need to be saved
- will be, and reinflating has to be done manually using the reinflate
- method because the get method and the -> operator must not change
- the internals of the class. Finally, attempting to reinflate when the
- pointer is being invalidated causes the following assertion errors:
-
- check_ptrace_stopped_lwp_gone: assertion `lp->stopped` failed.
- get_frame_pc: Assertion `frame->next != NULL` failed.
-
- As for performance concerns, my personal testing with `time make
- chec-perf GDB_PERFTEST_MODE=run` showed an actual reduction of around
- 10% of time running.
-
- This commit also adds a testcase that exercises the python/28856 bug with
- 7 different triggers, run, continue, step, backtrace, finish, up and down.
- Some of them can seem to be testing the same thing twice, but since this
- test relies on stale pointers, there is always a chance that GDB got lucky
- when testing, so better to test extra.
-
- Regression tested on x86_64, using both gcc and clang.

- but with native-extended-gdbserver I have instead:
- ...
- # of expected passes 8
- # of unexpected failures 4

-
- The extra FAILs are of the form:
- ...
- (gdb) detach^M

- [Inferior 1 (process 28985) detached]^M
- (gdb) FAIL: gdb.server/connect-with-no-symbol-file.exp: sysroot=: \
- action=permission: connection to GDBserver succeeded
- ...
- and are due to the fact that the actual gdb output doesn't match the regexp:
- ...
- gdb_test "detach" \
- ".*Detaching from program: , process.*Ending remote debugging.*" \
- "connection to GDBserver succeeded"
- ...
-
- With native, the actual gdb output is:
- ...
- (gdb) detach^M
- Detaching from pid process 29657^M
- Ending remote debugging.^M
- [Inferior 1 (process 29657) detached]^M
- (gdb) Remote debugging from host ::1, port 51028^M
- ...
- and because the regexp doesn't match, it triggers an implicit clause for
- "Ending remote debugging" in gdb_test_multiple, which has the consequence
- that the FAIL is silent.
-
- Fix:
- - the regexp by making it less strict
- - the silent fail by rewriting into a gdb_test_multiple, and adding an
- explicit fail clause.

- lazy FPU register stacking. The same conditions are valid for other
- Cortex-M cores with FPU.
-
- This patch has been verified on a STM32F4-Discovery board by:
- a) writing a non-zero value (lets use 0x1122334455667788 as an
- example) to all the D-registers in the main function
- b) configured the SysTick to fire
- c) in the SysTick_Handler, write some other value (lets use
- 0x0022446688aaccee as an example) to one of the D-registers (D0 as
- an example) and then do "SVC #0"
- d) in the SVC_Handler, write some other value (lets use
- 0x0099aabbccddeeff) to one of the D-registers (D0 as an example)
-
- In GDB, suspend the execution in the SVC_Handler function and compare
- the value of the D-registers for the SVC_handler frame and the
- SysTick_Handler frame. With the patch, the value of the modified
- D-register (D0) should be the new value (0x009..eff) on the
- SVC_Handler frame, and the intermediate value (0x002..cee) for the
- SysTick_Handler frame. Now compare the D-register value for the
- SysTick_Handler frame and the main frame. The main frame should
- have the initial value (0x112..788).

- gdb: more infrun debug from breakpoint.c
- This commit adds additional infrun debug from the breakpoint.c file.
- The new debug output all relates to breakpoint condition evaluation.
-
- There is already some infrun debug emitted from the breakpoint.c file,
- so hopefully, adding more will not be contentious. I think the
- functions being instrumented make sense as part of the infrun process,
- the inferior stops, evaluates the condition, and then either stops or
- continues. This new debug gives more insight into that process.
-
- I had to make the bp_location* argument to find_loc_num_by_location
- const, and add a declaration for find_loc_num_by_location.

- There should be no user visible changes unless they turn on debug
- output.

- But given the pseudo-register numbers are above the number of real registers,

- Improve GDB's baseclass detection with typedefs
- When a class inherits from a typedef'd baseclass, GDB may be unable to
- find the baseclass if the user is not using the typedef'd name, as is
- tested on gdb.cp/virtbase2.exp; the reason that test case is working
- under gcc is that the dwarf generated by gcc links the class to the
- original definition of the baseclass, not to the typedef. If the
- inheritance is linked to the typedef, such as how clang does it,
- gdb.cp/virtbase2.exp starts failing.
-
- This can also be seen in gdb.cp/impl-this.exp, when attempting to print
- D::Bint::i, and GDB not being able to find the baseclass Bint.
-
- This happens because searching for baseclasses only uses the macro
- TYPE_BASECLASS_NAME, which returns the typedef'd name. However, we can't
- switch that macro to checking for typedefs, otherwise we wouldn't be
- able to find the typedef'd name anymore. This is fixed by searching for
- members or baseclasses by name, we check both the saved name and the
- name after checking for typedefs.
-
- This also fixes said long-standing bug in gdb.cp/impl-this.exp when the
- compiler adds information about typedefs in the debuginfo.

- gdb/testsuite: handle invalid .exp names passed in TESTS
- I ran some tests like:
-
- $ make check-gdb TESTS="gdb.base/break.exp"
-
- then, then I went to rerun the tests later, I managed to corrupt the
- command line, like this:
-
- $ make check-gdb TESTS="gdb.base/breakff.exp"
-
- the make command did exit with an error, but DejaGnu appeared to
- report that every test passed! The tail end of the output looks like
- this:
-
- Illegal Argument "no-matching-tests-found"
- try "runtest --help" for option list
- === gdb Summary ===
-
- # of expected passes 115
- /tmp/build/gdb/gdb version 13.0.50.20220831-git -nw -nx -iex "set height 0" -iex "set width 0" -data-directory /tmp/build/gdb/testsuite/../data-directory

- make: *** [Makefile:13565: check-gdb] Error 2
-
- For a while, I didn't spot that DejaGnu had failed at all, I saw the
- 115 passes, and thought everything had run correctly - though I was
- puzzled that make was reporting an error.
-
- What happens is that in gdb/testsuite/Makefile, in the check-single
- rule, we first run DejaGnu, then run the dg-add-core-file-count.sh
- script, and finally, we use sed to extract the results from the
- gdb.sum file.
-
- In my case, with the invalid test name, DejaGnu fails, but the
- following steps are still run, the final result, the 115 passes, is
- then extracted from the pre-existing gdb.sum file.
-
- If I use 'make -jN' then the 'check-parallel' rule, rather than the
- 'check-single' rule is used. In this case the behaviour is slightly
- different, the tail end of the output now looks like this:
-
- No matching tests found.

- variants in the files for <tool>.

-
- Rather than DejaGnu failing, we now get a nice 'No matching tests
- found' message, followed by some other noise. This other noise is
- first `find` failing, followed by the dg-extract-results.py script
- failing.
-
- What happens here is that, in the check-parallel rule, the outputs
- directory is deleted before DejaGnu is invoked. Then we try to run
- all the tests, and finally we use find and dg-extract-results.py to
- combine all the separate .sun and .log files together. However, if
- there are no tests run then the outputs/ directory is never created,
- so the find command and consequently the dg-extract-results.py script,
- fail.
-
- This commit aims to fix the following issues:
-
- (1) For check-single and check-parallel rules, don't run any of the
- post-processing steps if DejaGnu failed to run. This will avoid all
- the noise after the initial failure of DejaGnu,
-
- (2) For check-single ensure that we don't accidentally report
- previous results, this is related to the above, but is worth calling
- out as a separate point, and
-
- (3) For check-single, print the 'No matching tests found' message
- just like we do for a parallel test run. This makes the parallel and
- non-parallel testing behaviour more similar, and I think is clearer
- than the current 'Illegal Argument' error message.
-
- Points (1) and (2) will be handled by moving the post processing steps
- inside an if block within the recipe. For check-single I propose
- deleting the gdb.sum and gdb.log files before running DejaGnu, this is
- similar (I think) to how we delete the outputs/ directory in the
- check-parallel rule.
-
- For point (3) I plan to split the check-single rule in two, the
- existing check-single will be renamed do-check-single, then a new
- check-single rule will be added. The new check-single rule can either
- depend on the new do-check-single, or will ensure the 'No matching
- tests found' message is printed when appropriate.

- gdb/disasm: better intel flavour disassembly styling with Pygments
- This commit was inspired by this stackoverflow post:
-
- https://stackoverflow.com/questions/73491793/why-is-there-a-%C2%B1-in-lea-rax-rip-%C2%B1-0xeb3
-
- One of the comments helpfully links to this Python test case:
-
- from pygments import formatters, lexers, highlight
-
- def colorize_disasm(content, gdbarch):
- try:
- lexer = lexers.get_lexer_by_name("asm")
- formatter = formatters.TerminalFormatter()
- return highlight(content, lexer, formatter).rstrip().encode()
- except:
- return None
-
- print(colorize_disasm("lea [rip+0x211] # COMMENT", None).decode())
-
- Run the test case and you should see that the '+' character is
- underlined, and could be confused with a combined +/- symbol.
-
- What's happening is that Pygments is failing to parse the input text,
- and the '+' is actually being marked in the error style. The error
- style is red and underlined.
-
- It is worth noting that the assembly instruction being disassembled
- here is an x86-64 instruction in the 'intel' disassembly style, rather
- than the default att style. Clearly the Pygments module expects the
- att syntax by default.
-
- If we change the test case to this:
-
- from pygments import formatters, lexers, highlight
-
- def colorize_disasm(content, gdbarch):
- try:
- lexer = lexers.get_lexer_by_name("asm")
- lexer.add_filter('raiseonerror')
- formatter = formatters.TerminalFormatter()
- return highlight(content, lexer, formatter).rstrip().encode()
- except:
- return None
-
- res = colorize_disasm("lea rax,[rip+0xeb3] # COMMENT", None)
- if res:
- print(res.decode())
- else:
- print("No result!")
-
- Here I've added the call: lexer.add_filter('raiseonerror'), and I am
- now checking to see if the result is None or not. Running this and
- the test now print 'No result!' - instead of styling the '+' in the
- error style, we instead give up on the styling attempt.
-
- There are two things we need to fix relating to this disassembly
- text. First, Pygments is expecting att style disassembly, not the
- intel style that this example uses. Fortunately, Pygments also
- supports the intel style, all we need to do is use the 'nasm' lexer
- instead of the 'asm' lexer.
-
- However, this leads to the second problem; in our disassembler line we
- have '# COMMENT'. The "official" Intel disassembler style uses ';'
- for its comment character, however, gas and libopcodes use '#' as the
- comment character, as gas uses ';' for an instruction separator.
-
- Unfortunately, Pygments expects ';' as the comment character, and
- treats '#' as an error, which means, with the addition of the
- 'raiseonerror' filter, that any line containing a '#' comment, will
- not get styled correctly.
-
- However, as the i386 disassembler never produces a '#' character other
- than for comments, we can easily "fix" Pygments parsing of the
- disassembly line. This is done by creating a filter. This filter
- looks for an Error token with the value '#', we then change this into
- a comment token. Every token after this (until the end of the line)
- is also converted into a comment.
-
- In this commit I do the following:
-
- 1. Check the 'disassembly-flavor' setting and select between the
- 'asm' and 'nasm' lexers based on the setting. If the setting is not
- available then the 'asm' lexer is used by default,
-
- 2. Use "add_filter('raiseonerror')" to ensure that the formatted
- output will not include any error text, which would be underlined,
- and might be confusing,
-
- 3. If the 'nasm' lexer is selected, then add an additional filter
- that will format '#' and all other text on the line, as a comment,
- and
-
- 4. If Pygments throws an exception, instead of returning None,
- return the original, unmodified content. This will mean that this
- one instruction is printed without styling, but GDB will continue to
- call into the Python code to style later instructions.
-
- I haven't included a test specifically for the above error case,
- though I have manually check that the above case now styles
- correctly (with no underline). The existing style tests check that
- the disassembler styling still works though, so I know I've not
- generally broken things.
-
- One final thought I have after looking at this issue is that I wonder
- now if using Pygments for styling disassembly from every architecture
- is actually a good idea?
-
- Clearly, the 'asm' lexer is OK with att style x86-64, but not OK with
- intel style x86-64, so who knows how well it will handle other random
- architectures?
-
- When I first added this feature I tested it against some random
- RISC-V, ARM, and X86-64 (att style) code, and it seemed fine, but I
- never tried to make an exhaustive check of all instructions, so its
- quite possible that there are corner cases where things are styled
- incorrectly.
-
- With the above changes I think that things should be a bit better
- now. If a particular instruction doesn't parse correctly then our
- Pygments based styling code will just not style that one instruction.
- This is combined with the fact that many architectures are now moving
- to libopcodes based styling, which is much more reliable.
-
- So, I think it is fine to keep using Pygments as a fallback mechanism
- for styling all architectures, even if we know it might not be perfect
- in all cases.

-
- gdb: improve disassembler styling when Pygments raises an exception
- While working on another issue relating to GDB's use of the Python
- Pygments package for disassembly styling I noticed an issue in the
- case where the Pygments package raises an exception.
-
- The intention of the current code is that, should the Pygments package
- raise an exception, GDB will disable future attempts to call into the
- Pygments code. This was intended to prevent repeated errors during
- disassembly if, for some reason, the Pygments code isn't working.
-
- Since the Pygments based styling was added, GDB now supports
- disassembly styling using libopcodes, but this is only available for
- some architectures. For architectures not covered by libopcodes
- Pygments is still the only option.
-
- What I observed is that, if I disable the libopcodes styling, then
- setup GDB so that the Pygments based styling code will indicate an
- error (by returning None), GDB does, as expected, stop using the
- Pygments based styling. However, the libopcodes based styling will
- instead be used, despite this feature having been disabled.
-
- The problem is that the disassembler output is produced into a
- string_file buffer. When we are using Pygments, this buffer is
- created without styling support. However, when Pygments fails, we
- recreate the buffer with styling support.
-
- The problem is that we should only recreate the buffer with styling
- support only if libopcodes styling is enabled. This was an oversight
- in commit:

- gdb: add support for disassembler styling using libopcodes
-
- This commit:
-
- 1. Factors out some of the condition checking logic into two new
- helper functions use_ext_lang_for_styling and
- use_libopcodes_for_styling,
-
- 2. Reorders gdb_disassembler::m_buffer and gdb_disassembler::m_dest,
- this allows these fields to be initialised m_dest first, which means
- that the new condition checking functions can rely on m_dest being
- set, even when called from the gdb_disassembler constructor,
-
- 3. Make use of the new condition checking functions each time
- m_buffer is initialised,
-
- 4. Add a new test that forces the Python disassembler styling
- function to return None, this will cause GDB to disable use of
- Pygments for styling, and
-
- 5. When we reinitialise m_buffer, and re-disassemble the
- instruction, call reset the in-comment flag. If the instruction
- being disassembler ends in a comment then the first disassembly pass
- will have set the in-comment flag to true. This shouldn't be a
- problem as we will only be using Pygments, and thus performing a
- re-disassembly pass, if libopcodes is disabled, so the in-comment
- flag will never be checked, even if it is set incorrectly. However,
- I think that having the flag set correctly is a good thing, even if
- we don't check it (you never know what future uses might come up).

-
- gdb/testsuite: extend styling test for libopcodes styling
- This commit extends the gdb.base/style.exp test to cover disassembler
- styling using libopcodes (where available).
-
- The test will try to enable libopcode based styling, if this
- works (because such styling is available) then some tests are run to
- check that the output is styled, and that the styling can be disabled
- using 'set style disassembler enabled off'. If libopcodes styling is
- not available on the current architecture then these new tests will be
- skipped.
-
- I've moved the Python Pygments module check inside the
- test_disable_disassembler_styling function now, so that the test will
- be run even when Python Pygments is not available, this allows the new
- tests discussed above.
-
- If the Pygments module is not available then the Pygments based tests
- will be skipped just as they were before.

- gdb: update now gdbarch_register_name doesn't return nullptr
- After the previous few commit, gdbarch_register_name no longer returns

- gdb: final cleanup of various gdbarch_register_name methods
- Building on the previous commits, this commit goes through the various
- gdbarch_register_name methods and removes all the remaining 'return
- NULL' cases, I claim that these either couldn't be hit, or should be
- returning the empty string.
-
- In all cases the return of NULL was used if the register number being
- passed to gdbarch_register_name was "invalid", i.e. negative, or
- greater than the total number of declared registers. I don't believe
- either of these cases can occur, and the previous commit asserts that
- this is the case. As a result we can simplify the code by removing
- these checks. In many cases, where the register names are held in an
- array, I was able to add a static assert that the array contains the
- correct number of strings, after that, a direct access into the array
- is fine.
-
- I don't have any means of testing these changes.

- gdb/csky: remove nullptr return from csky_pseudo_register_name
- Building on the previous commits, in this commit I remove two
- instances of 'return NULL' from csky_pseudo_register_name, and replace
- them with a return of the empty string.
-
- These two are particularly interesting, and worth pulling into their
- own commit, because these returns of NULL appear to be depended on
- within other parts of the csky code.
-
- In csky-linux-tdep.c in the register collect/supply code, GDB checks
- for the register name being nullptr in order to decide if a target
- supports a particular feature or not. I've updated the code to check
- for the empty string.
-
- I have no way of testing this change.

-
- gdb: add asserts to gdbarch_register_name
- This commit adds asserts to gdbarch_register_name that validate the
- parameters, and the return value.
-
- The interesting thing here is that gdbarch_register_name is generated
- by gdbarch.py, and so, to add these asserts, I need to update the
- generation script.
-
- I've added two new arguments for Functions and Methods (as declared in
- gdbarch-components.py), these arguments are 'param_checks' and
- 'result_checks'. Each of these new arguments can be used to list some
- expressions that are then used within gdb_assert calls in the
- generated code.
-
- The asserts that validate the API as described in the comment I added
- to gdbarch_register_name a few commits back; the register number
- passed in needs to be a valid cooked register number, and the result
- being returned should not be nullptr.

-
- gdb: check for duplicate register names in selftest
- Building on the previous commit, this commit extends the register_name
- selftest to check for duplicate register names.
-
- If two registers in the cooked register set (real + pseudo registers)
- have the same name, then this will show up as duplicate registers in
- the 'info all-registers' output, but the user will only be able to
- interact with one copy of the register.
-
- In this commit I extend the selftest that I added in the previous
- commit to check for duplicate register names, I didn't include this
- functionality in the previous commit because one architecture needed
- fixing, and I wanted to keep those fixes separate from the fixes in
- the previous commit.
-
- The problematic architecture(s) are powerpc:750 and powerpc:604. In
- both of these cases the 'dabr' register appears twice, there's a
- definition of dabr in power-oea.xml which is included into both
- powerpc-604.xml and powerpc-750.xml. Both of these later two xml
- files also define the dabr register.
-
- I'm hopeful that this change shouldn't break anything, but I don't
- have the ability to actually test this change, however:
-
- On the gdbserver side, neither powerpc-604.xml nor powerpc-750.xml are
- mentioned in gdbserver/configure.srv, which I think means that
- gdbserver will never use these descriptions, and,
-
- Within GDB the problematic descriptions are held in the variables
- tdesc_powerpc_604 and tdesc_powerpc_750, which are only mentioned in
- the variants array in rs6000-tdep.c, this is used when looking up a
- description based on the architecture.
-
- For a native Linux target however, this will not be used as
- ppc_linux_nat_target::read_description exists, which calls
- ppc_linux_match_description, which I don't believe can return either
- of the problematic descriptions.
-
- This leaves the other native targets, FreeBSD, AIX, etc. These don't
- appear to override the ::read_description method, so will potentially
- return the problematic descriptions, but, in each case I think the
- ::fetch_registers and ::store_registers methods will ignore the dabr
- register, which will leave the register as <unavailable>.
-
- So, my proposed solution is to just remove the duplicate register from
- each of powerpc-604.xml and powerpc-750.xml, then regenerate the
- corresponding C++ source file. With this change made, the selftest
- now passes for all architectures.

-
- gdb: add a gdbarch_register_name self test, and fix some architectures
- This commit adds a self-test that checks that gdbarch_register_name
- never returns nullptr for any valid register number.
-
- Most architectures already met this requirement, there were just 6
- that failed the new selftest, and are updated in this commit.
-
- Beyond the self-tests I don't have any facilities to test that the
- architectures I've adjusted still work correctly.
-
- If you review all the various gdbarch_register_name implementations
- then you will see that there are far more architectures that seem like
- they might return nullptr in some situations, e.g. alpha, avr, bpf,
- etc. This commit doesn't attempt to address these cases as non of
- them are hit during the selftest. Many of these cases can never be
- hit, for example, in alpha_register_name GDB checks for a register
- number less than zero, this case can't happen and could be changed
- into an assert.
-
- A later commit in this series will have a general cleanup of all the
- various register_name methods, and remove all references to NULL from
- their code, however, as that commit will be mostly adjusting code that
- is never hit, I want to keep those changes separate.
-
- The selftest has been tested on x86-64, but I don't have access to
- suitable systems to fully test any of the *-tdep.c code I've changed
- in this commit.

- gdb/gdbarch: add a comment to gdbarch_register_name
- After the previous commit, this commit sets out to formalise the API
- for gdbarch_register_name. Not every architecture is actually in
- compliance with the API I set out here, but I believe that most are.
-
- I think architectures that don't comply with the API laid out here
- will fail the gdb.base/completion.exp test.
-
- The claims in the comment are I feel, best demonstrated with the
- asserts in this code:
-
- const char *
- gdbarch_register_name (struct gdbarch *gdbarch, int regnr)
- {
- gdb_assert (regnr >= 0);
- gdb_assert (regnr < gdbarch_num_cooked_regs (gdbarch));
-
- const char *name = gdbarch->register_name (gdbarch, regnr);
-
- gdb_assert (name != nullptr);
-
- return name;
- }
-
- Like I said, I don't believe every architecture follows these rules
- right now, which is why I'm not actually adding any asserts. Instead,
- this commit adds a comment to gdbarch_register_name, this comment is
- where I'd like to get to, rather than where we are right now.
-
- Subsequent commits will fix all targets to be in compliance with this
- comment, and will even add the asserts shown above to
- gdbarch_register_name.

- gdb/riscv: fix failure in gdb.base/completion.exp
- I noticed a test failure in gdb.base/completion.exp for RISC-V on
- a native Linux target, this is the failure:
-
- (gdb) FAIL: gdb.base/completion.exp: complete 'info registers '
-
- The problem is caused by a mismatch in the output of 'maint print
- registers' and the completion list for 'info registers'. The 'info
- registers' completion list contains less registers than
- expected. Additionally, the list of registers extracted from the
- 'maint print registers' list was wrong too, in some cases the test was
- grabbing the register number, rather than a register name,
-
- Both of these problems have the same root cause, riscv_register_name
- returns nullptr for some registers when it should return an empty
- string.
-
- The gdbarch_register_name API is not clearly documented anywhere, and
- at first glance it would appear that the function can return either
- nullptr, or an empty string to indicate that a register is not
- available on the current target. Indeed, there are plenty of places
- in GDB where we compare the output of gdbarch_register_name to both
- nullptr and '\0' in order to see if a register is supported or not,
- and there are plenty of targets that return empty string in some
- cases, and nullptr in others.
-
- However, the 'info registers' completion code (reg_or_group_completer)
- clearly depends on user_reg_map_regnum_to_name only returning nullptr
- when the passed in regnum is greater than the maximum possible
- register number (i.e. after all physical registers, pseudo-registers,
- and user-registers), this means that gdbarch_register_name should not
- be returning nullptr.
-
- I did consider "fixing" user_reg_map_regnum_to_name, if
- gdbarch_register_name returns nullptr, I could convert to an empty
- string at this point, but that felt like a real hack, so I discarded
- that plan.
-
- The next possibility I considered was "fixing" reg_or_group_completer
- to not rely on nullptr to indicate the end marker. Or rather, I could
- have reg_or_group_completer use gdbarch_num_cooked_regs, we know that
- we should check at least that many register numbers. Then, once we're
- passed that limit, we keep checking until we hit a nullptr. This
- would absolutely work, and didn't actually feel that bad, but, it
- still felt a little weird that gdbarch_register_name could return
- nullptr OR the empty string to mean the same thing, so I wondered if
- the "right" solution was to have gdbarch_register_name not return
- nullptr. With this in mind I tried an experiment:
-
- I added a self-test that, for each architecture, calls
- gdbarch_register_name for every register number up to the
- gdbarch_num_cooked_regs limit, and checks that the name is not
- nullptr.
-
- Only a handful of architectures failed this test, RISC-V being one of
- them.
-
- This seems to suggest that most architectures agree that the correct
- API for gdbarch_register_name is to return an empty string for
- registers that are not supported on the current target, and that
- returning nullptr is really a mistake.
-
- In this commit I will update the RISC-V target so that GDB no longer
- returns nullptr from riscv_register_name, instead we return the empty
- string.
-
- In subsequent commits I will add the selftest that I mention above,
- and will fix the targets that fail the selftest.
-
- With this change the gdb.base/completion.exp test now passes.

- The completion.exp test makes use of the capture_command_output proc

- Currently the capture_command_output proc tries to collect the
- complete command output in a single expect buffer, and what I see is
- an error caused by the expect buffer becoming full.
-
- This commit rewrites capture_command_output to make use of
- gdb_test_multiple to collect the command output line at a time, in
- this way we avoid overflowing the expect buffer.
-
- The capture_command_output proc has some logic for skipping a prefix
- pattern, which is passed in to the proc as an argument. In order to
- handle this correctly (only matching the prefix at the start of the
- command output), I use two gdb_test_multiple calls, the first spots
- and discards the echoed command and the (optional) prefix pattern, the
- second gdb_test_multiple call then collects the rest of the command
- output line at a time until a prompt is seen.
-
- There is one slight oddity with the current implementation, which I
- have changed in my rewrite, this does, slightly, change the behaviour
- of the proc.
-
- The current implementation uses this pattern:
-
- -re "[string_to_regexp ${command}]\[\r\n\]+${prefix}(.*)\[\r\n\]+$gdb_prompt $"
-
- Now a typical command output will look like this:
-
- output here\r\n
- (gdb)
-
- As the TCL regexp matching is greedy, TCL will try to match as much as
- possible in one part of the pattern before moving on to the next.
- Thus, when this matches against (.*)[\r\n]+, the (.*) will end up
- matching against 'output here\r' and the [\r\n]+ will match '\n' only.
-
- In short the previous implementation would leave the '\r' on the end
- of the returned text, but not the final trailing '\n'.
-
- Now clearly I could make a new version of capture_command_output that
- maintained this behaviour, but I couldn't see any reason to do this.
- So, my new implementation drops the final '\r\n' completely, in our
- example above we now return 'output here' with no '\r'.
-
- This change doesn't seem to affect any of the existing tests, but I
- thought it was worth mentioning.

- gdb/mi: new options for -data-disassemble command
- Now that the disassembler has two different strategies for laying out
- the opcode bytes of an instruction (see /r vs /b for the disassemble
- command), I wanted to add support for this to the MI disassemble
- command.
-
- Currently the -data-disassemble command takes a single 'mode' value,
- which currently has 6 different values (0 -> 5), 3 of these modes
- relate to opcode display.
-
- So, clearly I should just add an additional 3 modes to handle the new
- opcode format, right?
-
- No, I didn't think that was a great idea either.
-
- So, I wonder, could I adjust the -data-disassemble command in a
- backward compatible way, that would allow GDB to move away from using
- the mode value altogether?
-
- I think we can.
-
- In this commit, I propose adding two new options to -data-disassemble,
- these are:
-
- --opcodes none|bytes|display
- --source
-
- Additionally, I will make the mode optional, and default to mode 0 if
- no mode value is given. Mode 0 is the simplest, no source code, no
- opcodes disassembly mode.
-
- The two new options are only valid for mode 0, if they are used with
- any other mode then an error is thrown.
-
- The --opcodes option can add opcodes to the result, with 'bytes' being
- equivalent to 'disassemble /b' and 'display' being 'disassemble /r'.
-
- The --source option will enable the /s style source code display, this
- is equivalent to modes 4 and 5. There is no way, using the new
- command options to get the now deprecated /m style source code
- display, that is mode 1 and 3.
-
- My hope is that new users of the MI will not use the mode at all, and
- instead will just use the new options to achieve the output they need.
- Existing MI users can continue to use the mode, and will not need to
- be updated to use the new options.

-
- gdb/doc: update syntax of -data-disassemble command arguments
- The argument documentation for -data-disassemble looks like this:
-
- -data-disassemble
- [ -s @var{start-addr} -e @var{end-addr} ]
- | [ -a @var{addr} ]
- | [ -f @var{filename} -l @var{linenum} [ -n @var{lines} ] ]
- -- @var{mode}
-
- However, I believe, according to the 'Notation and Terminology'
- section, this means that the there are 3 optional location
- specification argument groups for the command, followed by a
- non-optional '-- mode'.
-
- However, this is not true, one of the location specifications must be
- given, i.e. we can't choose to give NO location specification, which
- is what the above implies.
-
- I propose that we change this to instead be:
-
- -data-disassemble
- ( -s @var{start-addr} -e @var{end-addr}
- | -a @var{addr}
- | -f @var{filename} -l @var{linenum} [ -n @var{lines} ] )
- -- @var{mode}
-
- By placing all the location specifications within '( ... )' we
- indication that these are a group, from which one of the options,
- separated by '|', must be selected.
-
- However, the 'Notation and Terminology' section only describes two
- uses for parenthesis: '( GROUP )*' and '( GROUP )+', in the first case
- GROUP is repeated zero or more times, and in the second GROUP is
- repeated 1 or more times.
-
- Neither of those exactly describe what I want, which is GROUP must
- appear exactly once. I propose to extend 'Notation and Terminology'
- to include '( GROUP )' which means that GROUP should appear exactly
- once.
-
- This change is important because, in a later commit, I want to add
- additional optional arguments to the -data-disassemble command, and
- things start to get confusing with the original syntax.

-
- gdb: disassembler opcode display formatting
- This commit changes the format of 'disassemble /r' to match GNU
- objdump. Specifically, GDB will now display the instruction bytes in
- as 'objdump --wide --disassemble' does.
-
- Here is an example for RISC-V before this patch:
-
- (gdb) disassemble /r 0x0001018e,0x0001019e
- Dump of assembler code from 0x1018e to 0x1019e:
- 0x0001018e <call_me+66>: 03 26 84 fe lw a2,-24(s0)
- 0x00010192 <call_me+70>: 83 25 c4 fe lw a1,-20(s0)
- 0x00010196 <call_me+74>: 61 65 lui a0,0x18
- 0x00010198 <call_me+76>: 13 05 85 6a addi a0,a0,1704
- 0x0001019c <call_me+80>: f1 22 jal 0x10368 <printf>
- End of assembler dump.
-
- And here's an example after this patch:
-
- (gdb) disassemble /r 0x0001018e,0x0001019e
- Dump of assembler code from 0x1018e to 0x1019e:
- 0x0001018e <call_me+66>: fe842603 lw a2,-24(s0)
- 0x00010192 <call_me+70>: fec42583 lw a1,-20(s0)
- 0x00010196 <call_me+74>: 6561 lui a0,0x18
- 0x00010198 <call_me+76>: 6a850513 addi a0,a0,1704
- 0x0001019c <call_me+80>: 22f1 jal 0x10368 <printf>
- End of assembler dump.
-
- There are two differences here. First, the instruction bytes after
- the patch are grouped based on the size of the instruction, and are
- byte-swapped to little-endian order.
-
- Second, after the patch, GDB now uses the bytes-per-line hint from
- libopcodes to add whitespace padding after the opcode bytes, this
- means that in most cases the instructions are nicely aligned.
-
- It is still possible for a very long instruction to intrude into the
- disassembled text space. The next example is x86-64, before the
- patch:
-
- (gdb) disassemble /r main
- Dump of assembler code for function main:
- 0x0000000000401106 <+0>: 55 push %rbp
- 0x0000000000401107 <+1>: 48 89 e5 mov %rsp,%rbp
- 0x000000000040110a <+4>: c7 87 d8 00 00 00 01 00 00 00 movl $0x1,0xd8(%rdi)
- 0x0000000000401114 <+14>: b8 00 00 00 00 mov $0x0,%eax
- 0x0000000000401119 <+19>: 5d pop %rbp
- 0x000000000040111a <+20>: c3 ret
- End of assembler dump.
-
- And after the patch:
-
- (gdb) disassemble /r main
- Dump of assembler code for function main:
- 0x0000000000401106 <+0>: 55 push %rbp
- 0x0000000000401107 <+1>: 48 89 e5 mov %rsp,%rbp
- 0x000000000040110a <+4>: c7 87 d8 00 00 00 01 00 00 00 movl $0x1,0xd8(%rdi)
- 0x0000000000401114 <+14>: b8 00 00 00 00 mov $0x0,%eax
- 0x0000000000401119 <+19>: 5d pop %rbp
- 0x000000000040111a <+20>: c3 ret
- End of assembler dump.
-
- Most instructions are aligned, except for the very long instruction.
- Notice too that for x86-64 libopcodes doesn't request that GDB group
- the instruction bytes. This matches the behaviour of objdump.
-
- In case the user really wants the old behaviour, I have added a new
- modifier 'disassemble /b', this displays the instruction byte at a
- time. For x86-64, which never groups instruction bytes, /b and /r are
- equivalent, but for RISC-V, using /b gets the old layout back (except
- that the whitespace for alignment is still present). Consider our
- original RISC-V example, this time using /b:
-
- (gdb) disassemble /b 0x0001018e,0x0001019e
- Dump of assembler code from 0x1018e to 0x1019e:
- 0x0001018e <call_me+66>: 03 26 84 fe lw a2,-24(s0)
- 0x00010192 <call_me+70>: 83 25 c4 fe lw a1,-20(s0)
- 0x00010196 <call_me+74>: 61 65 lui a0,0x18
- 0x00010198 <call_me+76>: 13 05 85 6a addi a0,a0,1704
- 0x0001019c <call_me+80>: f1 22 jal 0x10368 <printf>
- End of assembler dump.
-
- Obviously, this patch is a potentially significant change to the
- behaviour or /r. I could have added /b with the new behaviour and
- left /r alone. However, personally, I feel the new behaviour is
- significantly better than the old, hence, I made /r be what I consider
- the "better" behaviour.
-
- The reason I prefer the new behaviour is that, when I use /r, I almost
- always want to manually decode the instruction for some reason, and
- having the bytes displayed in "instruction order" rather than memory
- order, just makes this easier.
-
- The 'record instruction-history' command also takes a /r modifier, and
- has been modified in the same way as disassemble; /r gets the new
- behaviour, and /b has been added to retain the old behaviour.
-
- Finally, the MI command -data-disassemble, is unchanged in behaviour,
- this command now requests the raw bytes of the instruction, which is
- equivalent to the /b modifier. This means that the MI output will
- remain backward compatible.

- Add another test for the output of MI command -data-disassemble. The

- by a single space.
-
- We also check that the bytes are in the correct order, that is, the
- first byte is from the lowest address, and subsequent bytes are from
- increasing addresses.
-
- The motivation for this test (besides more tests being generally good)
- is that I plan to make changes to how opcode bytes are displayed in
- the disassembler output, and I want to ensure that I don't break any
- existing MI behaviour.

- objcopy: avoid "shadowing" of remove() function name
- remove() is a standard library function (declared in stdio.h), which
- triggers a "shadows a global declaration" warning with some gcc versions.

- RISC-V: drop stray INSN_ALIAS flags
- FENCE.TSO isn't an alias. ZIP and UNZIP in the long run likely are, but
- presently they aren't. This fixes disassembly of these insns with
- -Mno-aliases.
-
-2022-09-30 Jan Beulich <jbeulich@suse.com>
-
- RISC-V: re-arrange opcode table for consistent alias handling
- For disassembly to pick up aliases in favor of underlying insns (helping
- readability in the common case), the aliases need to come ahead of the
- "base" insns. Slightly more code movement is needed because of insns
- with the same name needing to stay next to each other.
-
- Note that the "rorw" alias entry also has the missing INSN_ALIAS added
- here.

- Clone a few testcases to exercise -Mno-aliases some more, better
- covering the differences between the default and that disassembly mode.

- up-to-date but i386-init.h is missing), i386-init.h also needs
- mentioning as a dependency somewhere: Add a fake dependency for
- i386-opc.lo ("fake" because i386-opc.c doesn't include that header).
-
- At the same time use $(AM_V_GEN) in the actual rule, replacing the
- earlier (open-coded) "echo". And while there also drop a duplicate
- dependency of i386-gen.o on i386-opc.h.

- should aim at emitting the "best" possible error, which will typically

- x86/Intel: restrict suffix derivation
- While in some cases deriving an AT&T-style suffix from an Intel syntax
- memory operand size specifier is necessary, in many cases this is not
- only pointless, but has led to the introduction of various workarounds:
- Excessive use of IgnoreSize and NoRex64 as well as the ToDword and
- ToQword attributes. Suppress suffix derivation when we can clearly tell
- that the memory operand's size isn't going to be needed to infer the
- possible need for the low byte/word opcode bit or an operand size prefix
- (0x66 or REX.W).
-
- As a result ToDword and ToQword can be dropped entirely, plus a fair
- number of IgnoreSize and NoRex64 can also be got rid of. Note that
- IgnoreSize needs to remain on legacy encoded SIMD insns with GPR
- operand, to avoid emitting an operand size prefix in 16-bit mode. (Since
- 16-bit code using SIMD insns isn't well tested, clone an existing
- testcase just enough to cover a few insns which are potentially
- problematic but are being touched here.)
-
- Note that while folding the VCVT{,T}S{S,D}2SI templates, VCVT{,T}SH2SI
- isn't included there. This is to fulfill the request of not allowing L
- and Q suffixes there, despite the inconsistency with VCVT{,T}S{S,D}2SI.

- RISC-V: Add privileged extensions without instructions/CSRs
- Currently, GNU Binutils does not support following privileged extensions:
-
- - 'Smepmp'
- - 'Svnapot'
- - 'Svpbmt'
-
- as they do not provide new CSRs or new instructions ('Smepmp' extends the
- privileged architecture CSRs but does not define the CSR itself). However,
- adding them might be useful as we no longer have to "filter" ISA strings
- just for toolchains (if full ISA string is given by a vendor, we can
- straightly use it).
-
- And there's a fact that supports this theory: there's already an
- (unprivileged) extension which does not provide CSRs or instructions (but
- only an architectural guarantee): 'Zkt' (constant timing guarantee for
- certain subset of RISC-V instructions).
-
- This simple commit simply adds three privileged extensions listed above.

- [gdb/c++] Print destructor the same for gcc and clang
- Consider the test-case contained in this patch.
-
- With g++ (7.5.0) we have for "ptype A":
- ...
- type = class A {
- public:
- int a;
-
- A(void);
- ~A();
- }
- ...
- and with clang++ (13.0.1):
- ...
- type = class A {
- public:
- int a;
-
- A(void);
- ~A(void);
- }
- ...
- and we observe that the destructor is printed differently.
-
- There's a difference in debug info between the two cases: in the clang case,
- there's one artificial parameter, but in the g++ case, there are two, and
- these similar cases are handled differently in cp_type_print_method_args.
-
- This is due to this slightly convoluted bit of code:
- ...
- i = staticp ? 0 : 1;
- if (nargs > i)
- {
- while (i < nargs)
- ...
- }
- else if (varargs)
- gdb_printf (stream, "...");
- else if (language == language_cplus)
- gdb_printf (stream, "void");
- ...
-
- The purpose of "i = staticp ? 0 : 1" is to skip the printing of the implicit
- this parameter.
-
- In commit 5f4d1085085 ("c++/8218: Destructors w/arguments"), skipping of other
- artificial parameters was added, but using a different method: rather than
- adjusting the potential loop start, it skips the parameter in the loop.
-
- The observed difference in printing is explained by whether we enter the loop:
- - in the clang case, the loop is not entered and we print "void".
- - in the gcc case, the loop is entered, and nothing is printed.
-
- Fix this by rewriting the code to:
- - always enter the loop
- - handle whether arguments need printing in the loop
- - keep track of how many arguments are printed, and
- use that after the loop to print void etc.
- such that we have the same for both gcc and clang:
- ...
- A(void);
- ~A(void);
- ...
-
- Note that I consider the discussion of whether we want to print:
- - A(void) / ~A(void), or
- - A() / ~A()
- out-of-scope for this patch.

- Constify target_desc declarations
- This patch changes various global target_desc declarations to const, thereby
- correcting a prominent source of ODR violations in PowerPC-related target code.
- The majority of files/changes are mechanical const-ifications accomplished by
- regenerating the C files in features/.
-
- This also required manually updating mips-linux-tdep.h, s390-linux-tdep.h,
- nios2-tdep.h, s390-tdep.h, arch/ppc-linux-tdesc.h, arch/ppc-linux-common.c,
- and rs6000-tdep.c.
-
- Patch tested against the sourceware trybot, and fully regression tested against
- our (Red Hat's) internal test infrastructure on Rawhide aarch64, s390x, x86_64,
- and powerpcle.
-
- With this patch, I can finally enable LTO in our GDB package builds. [Tested
- with a rawhide scratch build containing this patch.]

- cleanup: Add missing feature/ XML files to Makefile
- This patch adds some missing .xml files to features/Makefile so that when the
- directory's C files are regenerated, all files are appropriately remade.
-
- This has demonstrated that there have been several "misses" in regenerating
- files in this directory. Namely, arm-secext.c and sparc{32,64}-solaris.c. For
- the former case, there was what essentially amounts to a typo regarding the
- create feature function's name. In the later case, this file has missed at least
- one important update in July, 2020, when allocate_target_description was
- changed to return a unique pointer.

- gdb/source.c: Fix undefined behaviour dereferencing empty string
- When a source file's dirname is solely made up of directory separators
- we end up trying to dereference the last character of an empty string
- with std::string::back, which results in undefined behaviour. A typical
- use case where this can happen is when the root directory "/" is used as
- a compilation directory.
-
- With libstdc++.so.6.0.28 we get no out-of-bounds checks and the byte
- preceding the storage of the empty string is returned. The character
- value of this byte depends on heap implementation and usage, but when
- this byte happens to hold the value of the directory separator character
- we go on to call std::string::pop_back on the empty string which results
- in an out_of_range exception which terminates GDB.
-
- Fix this by using path_join. prepare_path_for_appending ensures that the
- filename component is relative.
-
- The testsuite has been run before and after the change and no
- regressions were found.

-
- gdbserver: remove unused variable
-
- I removed an unused variable in handle_v_run. Pedro then pointed out
- that the for loop after it was also unused. After a period of smoke
- testing, no exceptions were found.
-
- Tested on x86_64-linux.

- The problem with warning in elf_object_p
- elfcode.h can emit three warnings in elf_object_p for various things,
- "section extending past end of file", "corrupt string table index",
- and "program header with invalid alignment". The problem with doing
- this is that the warning can be emitted for multiple possible targets
- as each one is tried. I was looking at a fuzzer testcase that had an
- object file with 6144 program headers, 5316 of which had invalid
- alignment. It would be bad enough to get 5316 messages all the same,
- but this object was contained in an archive and resulted in 4975776
- repeats.
-
- Some trimming can be done by not warning if the bfd is already marked
- read_only, as is done for the "section extending past end of file"
- warning, but that still results in an unacceptable number of
- warnings for object files in archives. Besides that, it is just wrong
- to warn about a problem detected by a target elf_object_p other than
- the one that actually matches. At some point we might have more
- target specific warnings.
-
- So what to do? One obvious solution is to remove the warnings.
- Another is to poke any warning strings into the target xvec, emitting
- them if that xvec is the final one chosen. This also has the benefit
- of solving the archive problem. A warning when recursing into
- _bfd_check_format for the first element of the archive (to find the
- correct target for the archive) will still be on the xvec at the point
- that target is chosen for the archive. However, target xvecs are
- read-only. Thus the need for per_xvec_warn to logically extend
- bfd_target with a writable field. I've made per_xvec_warn one larger
- than bfd_target_vector to provide one place for user code that makes
- private copies of target xvecs.

- gdb/testsuite/tui: start GDB with "set filename-display basename"
- The test gdb.tui/tui-missing-src.exp fails on my CI machine, and I
- concluded that it is caused by the long source directory name:
-
- /home/jenkins/workspace/binutils-gdb_master_linuxbuild/platform/jammy-amd64/target_board/unix/src/binutils-gdb
-
- The long name causes some particular redrawing that doesn't happen for
- shorter directories, and causes a Term::command call to return too
- early.
-
- This can be reproduced by cloning the binutils-gdb repo in a directory
- with a name similar to the one shown above.

- When running the `Term::command "step"` just before, GDB writes the
- "step", which makes the `wait_for` proc go in the "looking for the
- prompt" mode, to know when the command's execution is complete. As some
- new output appears, lines that must disappear are deleted using the
- "Delete Line" operation [1] and some new ones are drawn. The source

-
- What happened is: GDB wrote the "step" command, which make the
- `wait_for` proc go in its "looking for the prompt" mode. However,
- curses decided to redraw whatever scrolled up to line 17 using some
- standard character insertion operations:
-
- +++ Cursor Down (1), cursor: (16, 0) -> (17, 0)
- +++ Inserting string '('
- +++ Inserted char '(', cursor: (17, 0) -> (17, 1)
- +++ Inserted string '(', cursor: (17, 0) -> (17, 1)
- +++ Inserting string 'g'
- +++ Inserted char 'g', cursor: (17, 1) -> (17, 2)
- +++ Inserted string 'g', cursor: (17, 1) -> (17, 2)
- +++ Inserting string 'd'
- +++ Inserted char 'd', cursor: (17, 2) -> (17, 3)
- +++ Inserted string 'd', cursor: (17, 2) -> (17, 3)
- +++ Inserting string 'b'
- +++ Inserted char 'b', cursor: (17, 3) -> (17, 4)
- +++ Inserted string 'b', cursor: (17, 3) -> (17, 4)
- +++ Inserting string ')'
- +++ Inserted char ')', cursor: (17, 4) -> (17, 5)
- +++ Inserted string ')', cursor: (17, 4) -> (17, 5)
- +++ Inserting string ' '
- +++ Inserted char ' ', cursor: (17, 5) -> (17, 6)
- +++ Inserted string ' ', cursor: (17, 5) -> (17, 6)
-
- And that causes `wait_for` to think the "step" command is complete.
- This is wrong, as the prompt at line 17 isn't the prompt drawn after the
- completion of the "step" command. The subsequent tests now run with a
- partially updated screen (what is shown above) and obviously fail.
-
- The ideal way to fix this would be for `wait_for` to be smarter, to
- avoid it confusing the different prompts drawn.
-
- However, I would also like to reduce the variations in TUI test results
- due to the directories (source and build) in which tests are ran. TUI
- tests are more prone to differences in test results due to variations in
- directory names than other tests, as it makes curses take different
- redrawing decisions. So in this patch, I propose to make TUI tests use
- "set filename-display basename", which makes GDB omit directory names
- when it prints file names. This way, regardless of where you run the
- tests, you should get the same results (all other things being equal).
-
- Doing this happens to fix my failures and makes my CI happy (which in
- turns makes me happy). To be clear, I understand that this does not fix
- the root issue of `proc wait_for` being confused. However, it makes TUI
- test runs be more similar for everyone, such that there's less chance of
- TUI tests randomly failing for somebody. If some other change triggers
- the `wait_for` problem again in the future, hopefully everybody will see
- the problem and we can work on getting it fixed more easily than if just
- one unlucky person sees the problem.
-
- Note that there are other reasons why TUI tests could vary, like
- different curses library versions taking different re-drawing decisions.
- However, I think my change is a good step towards more stable test
- results.

- gdb/testsuite/lib/future.exp: follow dejagnu default_target_compile
- GDB's testsuite can override dejagnu's default_target_compile if the
- system provided dejagnu installation does not provide support to compile
- languages GDB needs.
-
- Recent version of dejagnu (1.6.3, installed on RHEL-9) includes ba60272
- "Establish a default C compiler by evaluating [find_gcc] if no other
- compiler is given."[1]. This commit removed calls such as
- `set_board_info compiler "[find_gcc]"` from the various baseboards
- and has default_target_compile call `find_gcc` itself to find a compiler
- if none was specified by the board description.
-
- On systems with dejagnu-1.6.3, if GDB's overrides is needed to support
- languages still unknown to dejagnu, we end up in the following
- situation:
- - The system board files do not set the C compiler anymore,
- - GDB's replacement for default_target_compile assumes that the
- compiler should have been set up by the board file.
-
- In this situation, no one sets the C compiler for the board and as a
- result many test are not compiled and not executed:
-
- [...]
- Running .../gdb/testsuite/gdb.base/bt-on-error-and-warning.exp ...
- gdb compile failed, default_target_compile: No compiler to compile with
- Running .../gdb/testsuite/gdb.base/dprintf-non-stop.exp ...
- gdb compile failed, default_target_compile: No compiler to compile with
- Running .../gdb/testsuite/gdb.base/structs3.exp ...
- gdb compile failed, default_target_compile: No compiler to compile with
- [...]
-
- We are observing this error with ROCgdb[2], a downstream port of GDB
- supporting AMD GPUs. This port needs to use GDB's override of
- default_target_compile to compile HIP programs since dejagnu does not
- provide support for this language yet.
-
- This patch changes gdb_default_target_compile_1 in a similar way
- default_target_compile has been updated so both implementations remain
- compatible. Even if this is not strictly required by GDB just yet,
- I believe keeping both implementations in sync desirable.
-
- Using board files provided with dejagnu <=1.6.2 is still supported: if
- the compiler is set by the board file, gdb_default_target_compile_1 uses
- it and does not need `find_gcc`.
-
- Patch tested on x86_64 RHEL-9 and ubuntu-20.04 on top of GDB and ROCgdb.

- This patch introduces changes that allow the integration of vendor ISA
- extensions:
- * Define a list of vendor extensions (riscv_supported_vendor_x_ext)
- where vendor extensions can be added
- * Introduce a section with a table in the documentation where vendor
- extensions can be added
-
- To add a vendor extension that consists of instructions only,
- the following things need to be done:
- * Add the extension to the riscv_supported_vendor_x_ext list
- * Add lookup entry in riscv_multi_subset_supports
- * Documenting the extension in c-riscv.texti
- * Add test cases for all instructions
- * Add MATCH*/MASK* constants and DECLARE_INSN() for all instructions
- * Add new instruction class to enum riscv_insn_class
- * Define the instructions in riscv_opcodes
- * Additional changes if necessary (depending on the instructions)

- [gdb/symtab] Add all_comp_units/all_type_units views on all_units
- Add all_comp_units/all_type_units views on all_units.
-
- Having the views allows us to:
- - easily get the number of CUs or TUs in all_units, and
- - easily access the nth CU or TU.
-
- This minimizes the use of tu_stats.nr_tus.

- gdb/python: restrict the names accepted by gdb.register_window_type
- I noticed that, from Python, I could register a new TUI window that
- had whitespace in its name, like this:
-
- gdb.register_window_type('my window', MyWindowType)
-
- however, it is not possible to then use this window in a new TUI
- layout, e.g.:
-
- (gdb) tui new-layout foo my window 1 cmd 1
- Unknown window "my"
- (gdb) tui new-layout foo "my window" 1 cmd 1
- Unknown window ""my"
- (gdb) tui new-layout foo my\ window 1 cmd 1
- Unknown window "my\"
-
- GDB clearly uses the whitespace to split the incoming command line.
-
- I could fix this by trying to add a mechanism by which we can use
- whitespace within a window name, but it seems like an easier solution
- if we just forbid whitespace within a window name. Not only is this
- easier, but I think this is probably the better solution, identifier
- names with spaces in would mean we'd need to audit all the places a
- window name could be printed and ensure that the use of a space didn't
- make the output ambiguous.
-
- So, having decided to disallow whitespace, I then thought about other
- special characters. We currently accept anything as a window name,
- and I wondered if this was a good idea.
-
- My concerns were about how special characters used in a window name
- might cause confusion, for example, we allow '$' in window names,
- which is maybe fine now, but what if one day we wanted to allow
- variable expansion when creating new layouts? Or what about starting
- a window name with '-'? We already support a '-horizontal' option,
- what if we want to add more in the future? Or use of the special
- character '{' which has special meaning within a new layout?
-
- In the end I figured it might make sense to place some restrictive
- rules in place, and then relax the rules later if/when users complain,
- we can consider each relaxation as its requested.
-
- So, I propose that window names should match this regular expression:
-
- [a-zA-Z][-_.a-zA-Z0-9]*
-
- There is a chance that there is user code in the wild which will break
- with the addition of this change, but hopefully adapting to the new
- restrictions shouldn't be too difficult.

- gdb/testsuite: Add test to step through function epilogue
- The testsuite implicitly tests GDB's ability to step through epilogues
- in multiple tests, without doing it explicitly anywhere. This is
- unfortunate, as clang does not emit epilogue information, so using clang
- on our testsuite makes many tests fail. This patch adds a central,
- explicit test for walking through the epilogue so we can safely remove
- this from other tests and have them working with clang.
-
- The test created attempts to step through a simple epilogue, an
- epilogue that ends on another epilogue, and epilogues leading to other
- function calls.

- gdb.base/skip.exp: Use finish to exit functions
- gdb.base/skip.exp was making use of a fixed number of step commands to
- exit some functions. This caused some problems when using clang to test
- GDB, as GDB would need fewer steps to reach the desired spots. For
- instance, when testing in the section "step after disabling 3", the log
- looks like this:
-
- Breakpoint 4, main () at binutils-gdb/gdb/testsuite/gdb.base/skip.c:32
- 32 x = baz ((bar (), foo ()));
- (gdb) step
- bar () at binutils-gdb/gdb/testsuite/gdb.base/skip1.c:21
- 21 return 1;
- (gdb) PASS: gdb.base/skip.exp: step after disabling 3: step 1
- step
- foo () at binutils-gdb/gdb/testsuite/gdb.base/skip.c:42
- 42 return 0;
- (gdb) PASS: gdb.base/skip.exp: step after disabling 3: step 2
- step
- main () at binutils-gdb/gdb/testsuite/gdb.base/skip.c:34
- 34 test_skip_file_and_function ();
- (gdb) step
- test_skip_file_and_function () at binutils-gdb/gdb/testsuite/gdb.base/skip.c:59
- 59 test_skip ();
- (gdb) FAIL: gdb.base/skip.exp: step after disabling 3: step 3
- step
- test_skip () at binutils-gdb/gdb/testsuite/gdb.base/skip.c:48

- (gdb) PASS: gdb.base/skip.exp: step after disabling 3: step 4
- step
- test_skip_file_and_function () at binutils-gdb/gdb/testsuite/gdb.base/skip.c:60
- 60 skip1_test_skip_file_and_function ();
- (gdb) FAIL: gdb.base/skip.exp: step after disabling 3: step 5
-
- This shows that the feature is working but because the inferior lands in
- a different location, it registers as a failure. Seeing as along with
- this difference, there are also some differences that depend on gcc
- versions (where gdb might stop back at line 32 before entering foo), it
- would not be easy to test for this behavior using steps and analzing
- where the inferior stops at each point. On the other hand, using
- gdb_step_until is not feasible because we'd possibly gloss over stepping
- into baz and rendering the whole test useless. Instead, skip.exp now
- uses finish to leave functions, synchronizing through compilers and
- compiler versions. Some test names were also changed to be a bit more
- descriptive. The new log looks like this, independently of compiler used:
-
- Breakpoint 4, main () at binutils-gdb/gdb/testsuite/gdb.base/skip.c:32
- 32 x = baz ((bar (), foo ()));

- This difference only happens when GDB's configure is ran using a

-
- This commit fixes this by switching those hardcoded steps to

- Change gdb.base/skip-solib.exp deal with lack of epilogue information
- When running gdb.base/skip-solib.exp, the backtrace tests could fail with
- compilers that associated epilogue instructions with the last statement
- line of the function, instead of associating it with the closing brace,
- despite the feature being fully functional. As an example, when testing
- skipping the function square, the testsuite would show
-
- Breakpoint 1, main () at (...)/binutils-gdb/gdb/testsuite/gdb.base/skip-solib-main.c:5
- 5 return square(0);
- (gdb) step

- Which means that the feature is working, the testsuite is just

- gdb/testsuite: Add a proc to test where compiler links the epilogue
- Different compilers link the epilogue of functions to different lines.
- As an example, gcc links it to the closing brace of the function,

- difference is important for the testsuite, since the where GDB will land
- after a step can be wildly different. Where possible, this dependency
- should be side-stepped in the testsuite, but it isn't always possible,

- But most of them has a reasoning to keep them:

- - Cx : Same as "Ct" except it has a constraint to have rd == rs2
- (similar to "Cw"). Although it hasn't used, its role is clear
- enough to implement a new instruction with this operand type.
- - Vf, Ve : Used by vector AMO instructions (not ratified and real
- instructions are not upstreamed yet).
- - [, ] : Unused tokenization symbols. Reserving them is not harmful
- and a vendor may use this symbol for special purposes.
-
- ... except "b". I could not have found any reference to this operand type
- except it works like the "s" operand type. Historically, it seems... it's
- just unused from the beginning. Its role is not clear either.

- gdbsupport: convert FILEIO_* macros to an enum
- Converting from free-form macros to an enum gives a bit of type-safety.
- This caught places where we would assign host error numbers to what
- should contain a target fileio error number, for instance in
- target_fileio_pread.
-
- I added the FILEIO_SUCCESS enumerator, because
- remote.c:remote_hostio_parse_result initializes the remote_errno output
- variable to 0. It seems better to have an explicit enumerator than to
- assign a value for which there is no enumerator. I considered
- initializing this variable to FILEIO_EUNKNOWN instead, such that if the
- remote side replies with an error and omits the errno value, we'll get
- an errno that represents an error instead of 0 (which reprensents no
- error). But it's not clear what the consequences of that change would
- be, so I prefer to err on the side of caution and just keep the existing
- behavior (there is no intended change in behavior with this patch).
-
- Note that remote_hostio_parse_resul still reads blindly what the remote
- side sends as a target errno into this variable, so we can still end up
- with a nonsensical value here. It's not good, but out of the scope of
- this patch.
-
- Convert host_to_fileio_error and fileio_errno_to_host to return / accept
- a fileio_error instead of an int, and cascade the change in the whole
- chain that uses that.

- The problem is this line in path_join:
-
- gdb_assert (strlen (path) == 0 || !IS_ABSOLUTE_PATH (path));
-
- ... where `path` is "x". IS_ABSOLUTE_PATH eventually calls
- HAS_DRIVE_SPEC_1:
-
- #define HAS_DRIVE_SPEC_1(dos_based, f) \
- ((f)[0] && ((f)[1] == ':') && (dos_based))
-
- This macro accesses indices 0 and 1 of the input string. However, `f`
- is a string_view of length 1, so it's incorrect to try to access index
- 1. We know that the string_view's underlying object is a null-terminated
- string, so in practice there's no harm. But as far as the string_view
- is concerned, index 1 is considered out of bounds.
-
- This patch makes the easy fix, that is to change the path_join parameter
- from a vector of to a vector of `const char *`. Another solution would
- be to introduce a non-standard gdb::cstring_view class, which would be a
- view over a null-terminated string. With that class, it would be
- correct to access index 1, it would yield the NUL character. If there
- is interest in having this class (it has been mentioned a few times in
- the past) I can do it and use it here.
-
- This was found by running tests such as gdb.ada/arrayidx.exp, which
- produce 1-char long filenames, so adding a new test is not necessary.

- PR29573, addr2line doesn't display file/line for local symbols
- The DWARF standard is clear that DW_AT_linkage_name is optional.
- Compilers may not provide the attribute on functions and variables,
- even though the language mangles names. g++ does not for local
- variables and functions. Without DW_AT_linkage_name, mangled object
- file symbols can't be directly matched against the source-level
- DW_AT_name in DWARF info. One possibility is demangling the object
- file symbols, but that comes with its own set of problems:
- 1) A demangler might not be available for the compiler/language.
- 2) Demangling doesn't give the source function name as stored in
- DW_AT_name. Class and template parameters must be stripped at
- least.
-
- So this patch takes a simpler approach. A symbol matches DWARF info
- if the DWARF address matches the symbol address, and if the symbol
- name contains the DWARF name as a sub-string. Very likely the name
- matching is entirely superfluous.

- gdb/testsuite: add a debuginfod-support.exp helper library
- We currently have a single test for GDB's debuginfod support, this is
- gdb.debuginfod/fetch_src_and_symbols.exp, this script does all the
- setup, starts debuginfod, and then does the testing.
-
- This commit tries to split the existing script in two, there is a new
- library lib/debuginfod-support.exp, which contains a helper functions
- related to running debuginfod tests. All the code in the new library
- is basically copied from the existing test case (which is why I
- retained the copyright date range on the new library), with some minor
- adjustments to try and make the code a little more generic.
-
- One change I made, for example, is the library offers functions to
- shut down debuginfod, previously we just relied on expect shutting
- down debuginfod when dejagnu completed.
-
- The existing test script is updated to make use of the new library
- code, and this test is still passing for me. The only change in the
- test results is a single test where I changed the name to remove the
- port number from the test name - the port number can change from run
- to run, so could make it hard to compare test results.
-
- I have also done a little light house keeping on the original test
- script, updating and adding new comments, and making use of
- proc_with_prefix in a couple of places.

- BFD error message suppression test case
- This commit adds a GDB test case which tests GDB's BFD error handler
- hook for suppressing output of all but the first identical messages.
-
- See the comment at the beginning of bfd-errors.exp for details about
- this new test.
-
- I've tested this test for both 32- and 64-bit ELF files and also
- on both little endian and big endian machines. It also works for
- both native and remote targets. The only major restriction is that
- it only works for ELF targets.

-
- Suppress printing of superfluous BFD error messages
- This commit adds a hook to the BFD error handler for suppressing
- identical messages which have been output once already.
-
- It's motivated by this Fedora bug...
-
- https://bugzilla.redhat.com/show_bug.cgi?id=2083315
-
- ...in which over 900,000 BFD error messages are output when attaching
- to firefox. From the bug report, the messages all say:
-
- BFD: /usr/lib/debug/usr/lib64/firefox/libxul.so-100.0-2.fc35.x86_64.debug: attempt to load strings from a non-string section (number 38)
-
- Since there's no (additional) context which might assist the user in
- determining what's wrong, there's really no point in outputting more
- than one message. Of course, if BFD should output some
- other/different message, it should be output too, but all future
- messages identical to those already output should be suppressed.
-
- For the firefox problem, it turned out that there were only 37
- sections, but something was referring to section #38. I haven't
- investigated further to find out how this came to be.
-
- Despite this problem, useful debugging might still be done, especially
- if the user doesn't care about debugging the problematic library.
-
- If it turns out that knowing the quantity of messages might be useful,
- I've implemented the suppression mechanism by keeping a count of each
- identical message. A new GDB command, perhaps a 'maintenance'
- command, could be added to print out each message along with the
- count. I haven't implemented this though because I'm not convinced of
- its utility. Also, the BFD message printer has support for BFD-
- specific format specifiers. The BFD message strings that GDB stores
- in its map are sufficient for distinguishing messages from each
- other, but are not identical to those output by BFD's default error
- handler. So, that problem would need to be solved too.

- [gdb/testsuite] Fix gdb.dwarf2/dw2-dir-file-name.exp for aarch64
- [ Another attempt at fixing the problem described in commit cd919f5533c
- ("[gdb/testsuite] Fix gdb.dwarf2/dw2-dir-file-name.exp"). ]
-
- When running the test-case gdb.dwarf2/dw2-dir-file-name.exp with
- aarch64-linux, we run into:
- ...
- (gdb) continue^M
- Continuing.^M
- ^M
- Breakpoint 2, compdir_missing__ldir_missing__file_basename () at \
- tmp-dw2-dir-file-name.c:999^M
- (gdb) FAIL: gdb.dwarf2/dw2-dir-file-name.exp: \
- compdir_missing__ldir_missing__file_basename: continue to breakpoint: \
- compdir_missing__ldir_missing__file_basename
- ...
-
- The breakpoint set at compdir_missing__ldir_missing__file_basename_label,
- address 0x400608 starts at a line entry:
- ...
- CU: tmp-dw2-dir-file-name.c:
- File name Line number Starting address View Stmt
- tmp-dw2-dir-file-name.c 999 0x400608 x
- tmp-dw2-dir-file-name.c 1000 0x40062c x
- tmp-dw2-dir-file-name.c - 0x40062c
- ...
- and therefore the breakpoint is printed without instruction address.
-
- In contrast, for x86_64-linux, we have the breakpoint printed with instruction
- address:
- ...
- (gdb) continue^M
- Continuing.^M
- ^M
- Breakpoint 2, 0x004004c1 in compdir_missing__ldir_missing__file_basename () \

- compdir_missing__ldir_missing__file_basename: continue to breakpoint: \
- compdir_missing__ldir_missing__file_basename
- ...
-
- The breakpoint set at compdir_missing__ldir_missing__file_basename_label,
- address 0x004004c1 doesn't start at a line entry:
- ...
- CU: tmp-dw2-dir-file-name.c:

- tmp-dw2-dir-file-name.c 1000 0x4004d3 x
- tmp-dw2-dir-file-name.c - 0x4004d3
- ...
-
- Fix this by:
- - unifying behaviour between the archs by adding an explicit line number entry
- for the address compdir_missing__ldir_missing__file_basename_label, making
- the FAIL reproducible on x86_64-linux.
- - expecting the breakpoint to be printed without instruction address.
-
- Tested on x86_64-linux and aarch64-linux.

- [gdb] Handle pending ^C after rl_callback_read_char
- In completion tests in various test-cases, we've been running into these
- "clearing input line" timeouts:
- ...
- (gdb) $cmd^GPASS: gdb.gdb/unittest.exp: tab complete "$cmd"
- FAIL: gdb.gdb/unittest.exp: tab complete "$cmd" (clearing input line) (timeout)
- ...
- where $cmd == "maintenance selftest name_that_does_not_exist".
-
- AFAIU, the following scenario happens:
- - expect sends "$cmd\t"
- - gdb detects the stdin event, and calls rl_callback_read_char until it
- comes to handle \t
- - readline interprets the \t as completion, tries to complete, fails to do so,
- outputs a bell (^G)
- - expect sees the bell, and proceeds to send ^C
- - readline is still in the call to rl_callback_read_char, and stores the
- signal in _rl_caught_signal
- - readline returns from the call to rl_callback_read_char, without having
- handled _rl_caught_signal
- - gdb goes to wait for the next event
- - expect times out waiting for "Quit", the expected reaction for ^C
-
- Fix this by handling pending signals after each call to rl_callback_read_char.
-
- The fix is only available for readline 8.x, if --with-system-readline provides
- an older version, then the fix is disabled due to missing function
- rl_check_signals.
-
- Tested on x86_64-linux.

- bfd: Stop using -Wstack-usage=262144 when built with Clang
- Some components of GNU Binutils will pass "-Wstack-usage=262144" when
- "GCC >= 5.0" is detected. However, Clang does not support "-Wstack-usage",
- despite that related configuration part in bfd/warning.m4 handles the latest
- Clang (15.0.0 as of this writing) as "GCC >= 5.0".
-
- The option "-Wstack-usage" was ignored when the first version of Clang is
- released but even this "ignoring" behavior is removed before Clang 4.0.0.
- So, if we give Clang "-Wstack-usage=262144", it generates a warning, making
- the build failure.

- compiler is identified as Clang.

- gdb/testsuite: introduce gdb_step_until
- Currently, GDB's testsuite uses a set amount of step commands to exit
- functions. This is a problem if a compiler emits different epilogue
- information from gcc, or emits no epilogue information at all. It was
- most noticeable if Clang was used to test GDB.
-
- To fix this unreliability, this commit introduces a new proc that will
- step the inferior until it is stopped at a line that matches the given
- regexp, or until it steps too many times - defined as an optional
- argument. If the line is found, it shows up as a single PASS in the
- test, and if the line is not found, a single FAIL is emitted.
-
- This patch only introduces this proc, but does not add it to any
- existing tests, these will be introduced in the following commit.

-
- explicitly test for stderr in gdb.base/dprintf.exp
- Not all compilers add stderr debug information when compiling a
- program. Clang, for instance, prefers to add nothing from standard
- libraries and let an external debug package have this information.
- Because of this, gdb.base/dprintf.exp was failing when GDB attempted to
- use dprintf as a call to fprintf(stderrr, ...), like this:
-
- (gdb) PASS: gdb.base/dprintf.exp: call: fprintf: set dprintf style to call
- continue
- Continuing.
- kickoff 1234
- also to stderr 1234
- 'stderr' has unknown type; cast it to its declared type
- (gdb) FAIL: gdb.base/dprintf.exp: call: fprintf: 1st dprintf (timeout)
-
- To avoid this false positive, we explicitly test to see if
- the compiler has added information about stderr at all, and abort
- testing dprintf as an fprintf call if it is unavailable.

- The difference is that with Clang we get:

-
- array_i = <integer_array>, ...
-
- These symbols are local static variables, and "main" is the name of

-
- fix gdb.base/access-mem-running.exp for clang testing
- Clang was optimizing global_var away because it was not being used
- anywhere. this commit fixes that by adding the attribute used it.
-
- update gdb.base/info-program.exp to not fail with clang
- The test specifically mentions that it doesn't care where the program
- stops, however it was still testing for a specific location. The clang
- compiler emits different line information for epilogue, so GDB reports a
- different stopping location, depending on the used compiler. With this
- patch the test works even with clang.

-
- gdb/testsuite: change gdb.base/nodebug.exp to not fail with clang
- Clang organizes the variables differently to gcc in the original version
- of this code, leading to the following differences when testing
- p (int*) &dataglobal + 1
-
- gcc:
- $16 = (int *) 0x404034 <datalocal>
-
- clang:
- $16 = (int *) 0x404034 <dataglobal8>
-
- However, since the important part of this test doesn't seem to be which
- symbol is linked, but rather if GDB is correctly increasing the
- address. This test was changed to actually measure address changes,
- instead of assuming the ordering and naming of symbols.

-
- ld: pe: Apply review suggestions on the existing exports/imports arrays
- Use a separate explicit max_exports/imports field, instead of
- deducing it from the number of allocated elements. Use a named
- constant for the incremental growth of the array.
-
- Use bool instead of int for boolean values.
-
- Remove an unnecessary if statement/scope in the def_file_free
- function.
-
- Add more verbose comments about parameters, and about insertion
- into an array of structs.
-
- Generally use unsigned integers for all array indices and sizes.
- The num_exports/imports fields are kept as is as signed integers,
- since changing them to unsigned would require a disproportionate
- amount of changes ti pe-dll.c to avoid comparisons between signed
- and unsigned.
-
- Simply use xrealloc instead of a check and xmalloc/xrealloc;
- xrealloc can take NULL as the first parameter (and does a similar
- check internally). (This wasn't requested in review though,
- but noticed while working on the code.)

-
- ld: pe: Improve performance of object file exclude symbol directives
- Store the list of excluded symbols in a sorted list, speeding up
- checking for duplicates when inserting new entries.
-
- This is done in the same way as is done for exports and imports
- (while the previous implementation was done with a linked list,
- based on the implementation for aligncomm).
-
- When linking object files with excluded symbols, there can potentially
- be very large numbers of excluded symbols (just like builds with
- exports can have a large number of exported symbols).
-
- This improves the link performance somewhat, when linking with large
- numbers of excluded symbols.
-
- The later actual use of the excluded symbols within pe-dll.c
- handles them via an unordered linked list still, though.

- [gdb] Fix abort in selftest run_on_main_thread with ^C
- When running selftest run_on_main_thread and pressing ^C, we can run into:
- ...
- Running selftest run_on_main_thread.
- terminate called without an active exception
-
- Fatal signal: Aborted
- ...
-
- The selftest function looks like this:
- ...
- static void
- run_tests ()
- {
- std::thread thread;
-
- done = false;
-
- {
- gdb::block_signals blocker;
-
- thread = std::thread (set_done);
- }
-
- while (!done && gdb_do_one_event () >= 0)
- ;
-
- /* Actually the test will just hang, but we want to test
- something. */
- SELF_CHECK (done);
-
- thread.join ();
- }
- ...
-
- The error message we see is due to the destructor of thread being called while
- thread is joinable.
-
- This is supposed to be taken care of by thread.join (), but the ^C prevents
- that one from being called, while the destructor is still called.
-
- Fix this by ensuring thread.join () is called (if indeed required) before the
- destructor using SCOPE_EXIT.

- [gdb/testsuite] Fix gdb.dwarf2/dw2-dir-file-name.exp for ppc64le
- In commit cd919f5533c ("[gdb/testsuite] Fix
- gdb.dwarf2/dw2-dir-file-name.exp"), I made gdb.dwarf2/dw2-dir-file-name.exp
- independent of prologue analyzers, using this change:
- ...
- - gdb_breakpoint $func
- + gdb_breakpoint *$func
- ...
-
- That however caused a regression on ppc64le. For PowerPC, as described in the
- ELFv2 ABI, a function can have a global and local entry point.
-
- Setting a breakpoint on *$func effectively creates a breakpoint for the global
- entry point, so if the function is entered through the local entry point, the
- breakpoint doesn't trigger.
-
- Fix this by reverting commit cd919f5533c, and setting the breakpoint on
- ${func}_label instead.
-
- Tested on x86_64-linux and ppc64le-linux.

- x86: avoid i386_dis_printf()'s staging area for a fair part of output
- While PR binutils/29483 has now been addressed differently, this
- originally proposed change still has its merits: Avoiding vsnprintf()
- for typically far more than half of the overall output results in a 2-3%
- performance gain in my testing (with debug builds of objdump, libbfd,
- and libopcodes).
-
- With that part of output no longer using staging_area[], the array also
- doesn't need to be quite as large anymore (the largest presently used
- size is 27, from "64-bit address is disabled").
-
- While limiting the scope of "res" it became apparent that
- - no caller cares about the function's return value,
- - the comment about the return value was wrong,
- - a particular positive return value would have been meaningless to the
- caller.
- Therefore convert the function to return "void" at the same time.

- RISC-V: PR28509, the default visibility symbol cannot be referenced by R_RISCV_JAL.
- When generating the shared object, the default visibility symbols may bind
- externally, which means they will be exported to the dynamic symbol table,
- and are preemptible by default. These symbols cannot be referenced by the
- non-pic R_RISCV_JAL and R_RISCV_RVC_JUMP. However, consider that linker
- may relax the R_RISCV_CALL relocations to R_RISCV_JAL or R_RISCV_RVC_JUMP,
- if these relocations are relocated to the plt entries, then we won't report
- error for them. Perhaps we also need the similar checks for the
- R_RISCV_BRANCH and R_RISCV_RVC_BRANCH relocations.

- gdbsupport: Fix config.status dependency
- Commit 171fba11ab27 ("Make GDBserver abort on internal error in development mode")

- it, it is found that CONFIG_STATUS_DEPENDENCIES value is not valid, making
- gdbsupport fail to build.
-
- Since the CONFIG_STATUS_DEPENDENCIES value is used in the Makefile, macro
- substitution must have a Makefile format but commit 171fba11ab27 used shell
- format "$srcdir/../bfd/development.sh".
-
- This commit fixes this issue by substituting "$srcdir" (shell format) to
- "$(srcdir)" (Makefile format). It preserves the dependency as Pedro
- intended and fixes the build problem.

- Note the different line numbers, 17 vs 19.
-
- The difference comes from the gdbarch_skip_prologue implementation.

- pck.adb 19 0x40258c x

- and which are represented like this internally in gdb:
- ...
- INDEX LINE ADDRESS IS-STMT PROLOGUE-END
- 0 17 0x0000000000402580 Y
- 1 17 0x0000000000402580 Y

- 4 END 0x00000000004025a0 Y
- ...
-
- The second entry is interpreted as end-of-prologue, so 0x402580 is used, while
- the actual end of the prologue is at 0x40258c:
- ...
- 0000000000402580 <pck__inspect>:

-
- Note that the architecture-specific prologue analyzer would have gotten this
- right:
- ...
- (gdb) p /x aarch64_analyze_prologue (gdbarch, pc, pc + 128, 0)
- $2 = 0x40258c

- Fix the FAIL by making the test-case more robust against problems in prologue
- skipping, by setting the breakpoint on line 19 instead.

- Fix endianness handling for arm record self tests
- v2:
-
- - Add 32-bit Arm instruction selftest
- - Refactored abstract memory reader into abstract instruction reader
- - Adjusted code to use templated type and to use host endianness as
- opposed to target endianness.
-
- The arm record tests handle 16-bit and 32-bit thumb instructions, but the
- code is laid out in a way that handles the 32-bit thumb instructions as
- two 16-bit parts.
-
- This is fine, but it is prone to host-endianness issues given how the two
- 16-bit parts are stored and how they are accessed later on. Arm is
- little-endian by default, so running this test with a GDB built with
- --enable-targets=all and on a big endian host will run into the following:
-
- Running selftest arm-record.
- Process record and replay target doesn't support syscall number -2036195
- Process record does not support instruction 0x7f70ee1d at address 0x0.
- Self test failed: self-test failed at ../../binutils-gdb/gdb/arm-tdep.c:14482
-
- It turns out the abstract memory reader class is more generic than it needs to
- be, and we can simplify the code a bit by assuming we have a simple instruction
- reader that only reads up to 4 bytes, which is the length of a 32-bit
- instruction.
-
- Instead of returning a bool, we return instead the instruction that has been
- read. This way we avoid having to deal with the endianness conversion, and use
- the host endianness instead. The Arm selftests can be executed on non-Arm
- hosts.
-
- While at it, Tom suggested adding a 32-bit Arm instruction selftest to increase
- the coverage of the selftests.

- (gdb) print /d (int) munmap (4198400, 4096)^M
- Invalid cast.^M
- (gdb) FAIL: gdb.base/break-main-file-remove-fail.exp: cmdline: \
- get integer valueof "(int) munmap (4198400, 4096)"
- ...
-
- The problem is that after starting the executable, the symbol has type
- "void (*) (void)":
- ...
- (gdb) p munmap
- $1 = {<text variable, no debug info>} 0x401030 <munmap@plt>
- (gdb) start
- ...
- (gdb) p munmap
- $2 = {void (void)} 0x7ffff7feb9a0 <__GI_munmap>
- ...
- which causes the "Invalid cast" error.
-
- Looking at the debug info for glibc for symbol __GI_munmap:
- ...
- <0><189683>: Abbrev Number: 1 (DW_TAG_compile_unit)
- <189691> DW_AT_name : ../sysdeps/unix/syscall-template.S
- <189699> DW_AT_producer : GNU AS 2.39.0

- <1896b3> DW_AT_external : 1
- <1896b4> DW_AT_low_pc : 0x10cad0
- <1896bc> DW_AT_high_pc : 37
- ...
- that's probably caused by this bit (or similar bits for other munmap aliases).
-
- This is fixed in gas on trunk by commit 5578fbf672e ("GAS: Add a return type
- tag to DWARF DIEs generated for function symbols").
-
- Work around this (for say gas 2.39) by explicitly specifying the prototype for
- munmap.
-
- Likewise for getpid in a couple of other test-cases.
-
- Tested on x86_64-linux.

- Add debuginfod support for objdump -S
- Currently objdump -S is not able to make use files downloaded from debuginfod.
- This is due to bfd_find_nearest_line_discriminator being unable to locate any
- separate debuginfo files in the debuginfod cache. Additionally objdump lacked
- a call to debuginfod_find_source in order to download missing source files.
-
- Fix this by using bfd_find_nearest_line_with_alt instead of

- [gdb/symtab] Support .debug_names section with TUs in .debug_info
- When running test-case gdb.cp/cpexprs-debug-types.exp on target board
- cc-with-debug-names/gdb:debug_flags=-gdwarf-5, we get an executable with
- a .debug_names section, but no .debug_types section. For dwarf-5, the TUs
- are no longer put in a separate unit, but instead they're put in the
- .debug_info section.
-
- When loading the executable, the .debug_names section is silently ignored
- because of this check in dwarf2_read_debug_names:
- ...
- if (map->tu_count != 0)
- {
- /* We can only handle a single .debug_types when we have an
- index. */
- if (per_bfd->types.size () != 1)
- return false;
- ...
- which triggers because per_bfd->types.size () == 0.
-
- The intention of the check is to make sure we don't have more that one
- .debug_types section, as can happen in a object file (see PR12984):
- ...
- $ grep "\.debug_types" 11.s
- .section .debug_types,"G",@progbits,wt.75c042c23a9a07ee,comdat
- .section .debug_types,"G",@progbits,wt.c59c413bf50a4607,comdat
- ...
-
- Fix this by:
- - changing the check condition to "per_bfd->types.size () > 1", and
- - handling per_bfd->types.size () == 0.

- sim/erc32: fix gdb with simulator build
- In commit:
-
- commit 7b01c1cc1d111ba0afa51e60fa9842d3b971e2d1
- Date: Mon Apr 4 22:38:04 2022 +0100
-
- sim: fixes for libopcodes styled disassembler
-
- changes were made to the simulator source to handle the new libopcodes
- disassembler styling API.
-
- Unfortunately, these changes broke building GDB with the erc32 (sparc)
- simulator, like this:
-
- ../src/configure --target=sparc-linux
- make all-gdb
- ....
- /usr/bin/ld: ../sim/erc32/libsim.a(interf.o): in function `sim_open':
- /tmp/build/sim/../../src/sim/erc32/interf.c:247: undefined reference to `fprintf_styled'
- collect2: error: ld returned 1 exit status
-
- The problem is that in commit 7b01c1cc1d11 the fprintf_styled function
- was added into sis.c. This file is only used when building the 'run'
- binary, that is, the standalone simulator, and is not included in the
- libsim.a library.
-
- Now, the obvious fix would be to move fprintf_styled into libsim.a,
- however, that turns out to be tricky.
-
- The erc32 simulator currently has two copies of the function run_sim,
- one in sis.c, and one in interf.c, both of these copies are global.
-
- Currently, the 'run' binary links fine, though I suspect this might be
- pure luck. When I tried moving fprintf_styled into interf.c, I ran
- into multiple-definition (of run_sim) errors. I suspect that by
- requiring the linker to pull in fprintf_styled from libsim.a I was
- changing the order in which symbols were loaded, and the linker was
- now seeing both copies of run_sim, while currently we only see one
- copy.
-
- The ideal solution of course, would be to merge the two similar, but
- slightly different copies of run_sim, and just use the one copy. Then
- we could safely move fprintf_styled into interf.c too, and all would
- be good.
-
- But I don't have time right now to start debugging the erc32
- simulator, so I wanted a solution that fixes the build without
- introducing multiple definition errors.
-
- The easiest solution I think is to just have two copies of
- fprintf_styled, one in sis.c, and one in interf.c. Unlike run_sim,
- these two copies are both static, so we will not run into multiple
- definition issues with this function. The functions themselves are
- not very big, so it's not a huge amount of duplicate code.
-
- I am very aware that this is not an ideal solution, and I would
- welcome anyone who wants to take on fixing the run_sim problem
- properly, and then cleanup the fprintf_styled duplication.

-
- Remove a call to clear_interpreter_hooks
- mi_interp::resume does not need to call clear_interpreter_hooks,
- because this is already done by interp_set.
-
- TUI stdout buffering cleanup
- The TUI checks against gdb_stdout to decide when to buffer. It seems
- much cleaner to me to simply record this as an attribute of the stream
- itself.
-
- Remove a ui-related memory leak
- gdb_setup_readline makes new streams and assigns to the various stream
- members of struct ui. However, these assignments cause the previous
- values to leak. As far as I can, this code is simply unnecessary and
- can be removed -- with the exception of the assignment to gdb_stdtarg,
- which is not initialized anywhere else.
-
- Remove tui_out_new
- tui_out_new is just a simple wrapper for 'new' and can be removed,
- simplifying gdb a tiny bit.
-
- Use scoped_restore in safe_parse_type
- This changes safe_parse_type to use scoped_restore rather than
- explicit assignments.
-
- Use member initialization in 'struct ui'
- This changes 'struct ui' to use member initialization. This is
- simpler to understand.
-
- Remove two unused members from mi_interp
- These members of mi_interp aren't used and can be removed.
-
- Remove obsolete filtering comment
- top.h has an obsolete comment about the use of _unfiltered.
-
- Remove the "for moment" comments
- A few spots setting some gdb output stream variables have a "for
- moment" comment. These comments aren't useful and I think the moment
- has passed -- these are permanent now.
-
- Use ui_out_redirect_pop in more places
- This changes ui_out_redirect_pop to also perform the redirection, and
- then updates several sites to use this, rather than explicit
- redirects.
-
- Free ui::line_buffer
- A ui initializes its line_buffer, but never calls buffer_free on it.
- This patch fixes the oversight. I found this by inspection.
-
- Remove some dead code
- This patch removes some dead code and an old FIXME. These no longer
- seem useful, even for documentation purposes.
-
- Let ui::input_fd be -1
- This changes gdb so that, if ui::input_fd is set to -1, then it will
- not be registered with the event loop. This is useful for the DAP
- support code I wrote, but as it turns out to also be useful to
- Insight, it seems best to check it in separately.

- These three registers all relate to the floating-point status and
- control mechanism on RISC-V. The fcsr is the floatint-point control
- status register, and consists of two parts, the flags (bits 0 to 4)
- and the rounding-mode (bits 5 to 7).
-
- The fcsr register is just one of many control/status registers (or
- CSRs) available on RISC-V. The fflags and frm registers are also
- CSRs. These CSRs are aliases for the relevant parts of the fcsr
- register. So fflags is an alias for bits 0 to 4 of fcsr, and frm is
- an alias for bits 5 to 7 of fcsr.
-
- This means that a user can change the floating-point rounding mode
- either, by writing a complete new value into fcsr, or by writing just
- the rounding mode into frm.
-
- How this impacts on GDB is like this: a target description could,
- legitimately include all three registers, fcsr, fflags, and frm. The
- QEMU target currently does this, and this makes sense. The target is
- emulating the complete system, and has all three CSRs available, so
- why not tell GDB about this.
-
- In contrast, the RISC-V native Linux target only has access to the
- fcsr. This is because the ptrace data structure that the kernel uses
- for reading and writing floating point state only contains a copy of
- the fcsr, after all, this one field really contains both the fflags
- and frm fields, so why carry around duplicate data.
-
- So, we might expect that the target description for the RISC-V native
- Linux GDB would only contain the fcsr register. Unfortunately, this
- is not the case. The RISC-V native Linux target uses GDB's builtin
- target descriptions by calling riscv_lookup_target_description, this
- will then add an fpu feature from gdb/features/riscv, either
- 32bit-fpu.xml or 64bit-fpu.xml. The problem, is that these features
- include an entry for fcsr, fflags, and frm. This means that GDB
- expects the target to handle reading and writing these registers. And
- the RISC-V native Linux target currently doesn't.
-
- In riscv_linux_nat_target::store_registers and
- riscv_linux_nat_target::fetch_registers only the fcsr register is
- handled, this means that, for RISC-V native Linux, the fflags and frm
- registers always show up as <unavailable> - they are present in the
- target description, but the target doesn't know how to access the
- registers.
-
- A final complication relating to these floating pointer CSRs is which
- target description feature the registers appear in.
-
- These registers are CSRs, so it would seem sensible that these
- registers should appear in the CSR target description feature.
-
- However, when I first added RISC-V target description support, I was
- using a RISC-V simulator that didn't support any CSRs other than the
- floating point related ones. This simulator bundled all the float
- related CSRs into the fpu target feature. This didn't feel completely
- unreasonable to me, and so I had GDB check for these registers in
- either target feature.
-
- In this commit I make some changes relating to how GDB handles the
- three floating point CSR:
-
- 1. Remove fflags and frm from 32bit-fpu.xml and 64bit-fpu.xml. This
- means that the default RISC-V target description (which RISC-V native
- FreeBSD), and the target descriptions created for RISC-V native Linux,
- will not include these registers. There's nothing stopping some other
- target (e.g. QEMU) from continuing to include all three of these CSRs,
- the code in riscv-tdep.c continues to check for all three of these
- registers, and will handle them correctly if they are present.
-
- 2. If a target supplied fcsr, but does not supply fflags and/or frm,
- then RISC-V GDB will now create two pseudo registers in order to
- emulate the two missing CSRs. These new pseudo-registers do the
- obvious thing of just reading and writing the fcsr register.
-
- 3. With the new pseudo-registers we can no longer make use of the GDB
- register numbers RISCV_CSR_FFLAGS_REGNUM and RISCV_CSR_FRM_REGNUM.
- These will be the numbers used if the target supplies the registers in
- its target description, but, if GDB falls back to using
- pseudo-registers, then new, unique numbers will be used. To handle
- this I've added riscv_gdbarch_tdep::fflags_regnum and
- riscv_gdbarch_tdep::frm_regnum, I've then updated the RISC-V code to
- compare against these fields.
-
- When adding the pseudo-register support, it is important that the
- pseudo-register numbers are calculated after the call to
- tdesc_use_registers. This is because we don't know the total number
- of physical registers until after this call, and the psuedo-register
- numbers must follow on from the real (target supplied) registers.
-
- I've updated some tests to include more testing of the fflags and frm
- registers, as well as adding a new test.

- gdb: Add tdesc_found_register function to tdesc API
- This commit adds a new function to the target description API within
- GDB. This new function is not used in this commit, but will be used
- in the next commit, I'm splitting it out into a separate patch for
- easier review.
-
- What I want to do in the next commit is check to see if a target
- description supplied a particular register, however, the register in
- question could appear in one of two possible features.
-
- The new function allows me to ask the tdesc_arch_data whether a
- register was found and assigned a particular GDB register number once
- all of the features have been checked. I think this is a much simpler
- solution than adding code such that, while checking each feature, I
- spot if the register I'm processing is the one I care about.
-
- No tests here as the new code is not used, but this code will be
- exercised in the next commit.

- gdb/riscv: improve (and fix) display of frm field in 'info registers'
- On RISC-V the FCSR (float control/status register) is split into two
- parts, FFLAGS (the flags) and FRM (the rounding mode). Both of these
- two fields are part of the FCSR register, but can also be accessed as
- separate registers in their own right. And so, we have three separate
- registers, $fflags, $frm, and $fcsr, with the last of these being the
- combination of the first two.
-
- Here's how the bits of FCSR are split between FRM and FFLAGS:
-
- ,--------- FFLAGS
- |---|
- 76543210 <----- FCSR
- |-|
- '--------------FRM
-
- Here's how GDB currently displays these registers:
-
- (gdb) info registers $fflags $frm $fcsr
- fflags 0x0 RD:0 NV:0 DZ:0 OF:0 UF:0 NX:0
- frm 0x0 FRM:0 [RNE (round to nearest; ties to even)]
- fcsr 0x0 RD:0 NV:0 DZ:0 OF:0 UF:0 NX:0 FRM:0 [RNE (round to nearest; ties to even)]
-
- Notice the 'RD' field which is present in both $fflags and $fcsr.
- This field contains the value of the FRM field, which makes sense when
- displaying the $fcsr, but makes no sense when displaying $fflags, as
- the $fflags doesn't include the FRM field.
-
- Additionally, the $fcsr already includes an FRM field, so the
- information in 'RD' is duplicated. Consider this:
-
- (gdb) set $frm = 0x3
- (gdb) info registers $fflags $frm $fcsr │
- fflags 0x0 RD:0 NV:0 DZ:0 OF:0 UF:0 NX:0
- frm 0x3 FRM:3 [RUP (Round up towards +INF)]
- fcsr 0x60 RD:3 NV:0 DZ:0 OF:0 UF:0 NX:0 FRM:3 [RUP (Round up towards +INF)]
-
- See how the 'RD' field in $fflags still displays 0, while the 'RD' and
- 'FRM' fields in $fcsr show the same information.
-
- The first change I propose in this commit is to remove the 'RD'
- field. After this change the output now looks like this:
-
- (gdb) info registers $fflags $frm $fcsr
- fflags 0x0 NV:0 DZ:0 OF:0 UF:0 NX:0
- frm 0x0 FRM:0 [RNE (round to nearest; ties to even)]
- fcsr 0x0 NV:0 DZ:0 OF:0 UF:0 NX:0 FRM:0 [RNE (round to nearest; ties to even)]
-
- Next, I spotted that the text that goes along with the 'FRM' field was
- not wrapped in the i18n markers for internationalisation, so I added
- those.
-
- Next, I spotted that:
-
- (gdb) set $frm=0x7
- (gdb) info registers $fflags $frm $fcsr
- fflags 0x0 RD:0 NV:0 DZ:0 OF:0 UF:0 NX:0
- frm 0x7 FRM:3 [RUP (Round up towards +INF)]
- fcsr 0xe0 RD:7 NV:0 DZ:0 OF:0 UF:0 NX:0 FRM:3 [RUP (Round up towards +INF)]
-
- Notice that despite being a 3-bit field, FRM masks to 2-bits.
- Checking the manual I can see that the FRM field is 3-bits, and is
- defined for all 8 values. That GDB masks to 2-bits is just a bug I
- think, so I've fixed this.
-
- Finally, the 'FRM' text for value 0x7 is wrong. Currently we use the
- text 'dynamic rounding mode' for value 0x7. However, this is not
- really correct.
-
- A RISC-V instruction can either encode the rounding mode within the
- instruction, or a RISC-V instruction can choose to use a global,
- dynamic rounding mode.
-
- So, for the rounding-mode field of an _instruction_ the value 0x7
- indicates "dynamic round mode", the instruction should defer to the
- rounding mode held in the FRM field of the $fcsr.
-
- But it makes no sense for the FRM of $fcsr to itself be set to
- 0x7 (dynamic rounding mode), and indeed, section 11.2, "Floating-Point
- Control and Status Register" of the RISC-V manual, says that a value
- of 0x7 in the $fcsr FRM field is invalid, and if an instruction has
- _its_ round-mode set to dynamic, and the FRM field is also set to 0x7,
- then an illegal instruction exception is raised.
-
- And so, I propose changing the text for value 0x7 of the FRM field to
- be "INVALID[7] (Dynamic rounding mode)". We already use the text
- "INVALID[5]" and "INVALID[6]" for the two other invalid fields,
- however, I think adding the extra "Dynamic round mode" hint might be
- helpful.
-
- I've added a new test that uses 'info registers' to check what GDB
- prints for the three registers related to this patch. There is one
- slight oddity with this test - for the fflags and frm registers, the
- test accepts both the "normal" output (as described above), but also
- allows these registers to be reported as '<unavailable>'.
-
- The reason why I accept <unavailable> is that currently, the RISC-V,
- native Linux target advertises these registers in its target
- description, but then doesn't support reading or writing of these
- registers, this results in the registers being reported as
- unavailable.
-
- A later patch in this series will address this issue, and will remove
- this check for <unavailable>.

- gdb, dwarf: create symbols for template tags without names
- The following GDB behavior was also reported as a GDB bug in
-
- https://sourceware.org/bugzilla/show_bug.cgi?id=28396
-
- I will reiterate the problem a bit and give some more information here.
- This patch closes the above mentioned bug.
-
- The DWARF 5 standard 2.23 'Template Parameters' reads:
-
- A template type parameter is represented by a debugging information
- entry with the tag DW_TAG_template_type_parameter. A template value
- parameter is represented by a debugging information entry with the tag
- DW_TAG_template_value_parameter. The actual template parameter entries
- appear in the same order as the corresponding template formal
- parameter declarations in the source progam.
-
- A type or value parameter entry may have a DW_AT_name attribute, whose
- value is a null-terminated string containing the name of the
- corresponding formal parameter.
-
- So the DW_AT_name attribute for DW_TAG_template_type_parameter and
- DW_TAG_template_value_parameter is optional.
-
- Within GDB, creating a new symbol from some read DIE usually requires the
- presence of a DW_AT_name for the DIE (an exception here is the case of
- unnamed namespaces or the existence of a linkage name).
-
- This patch makes the presence of the DW_AT_name for template value/type
- tags optional, similar to the unnamed namespaces.
-
- For unnamed namespaces dwarf2_name simply returns the constant string
- CP_ANONYMOUS_NAMESPACE_STR '(anonymous namespace)'. For template tags a
- case was added to the switch statement calling the
- unnamed_template_tag_name helper. Within the scope of parent which
- the template parameter is a child of, the helper counts the position
- of the template tag within the unnamed template tags and returns
- '<unnamedNUMBER>' where NUMBER is its position. This way we end up with
- unique names within the respective scope of the function/class/struct
- (these are the only currenltly supported template kinds within GDB and
- usually the compilers) where we discovered the template tags in.
-
- While I do not know of a way to bring GCC to emit template tags without
- names there is one for clang/icpx. Consider the following example
-
- template<typename A, typename B, typename C>
- class Foo {};
-
- template<typename, typename B, typename>
- class Foo;
-
- int main () {
- Foo<double, int, float> f;
- return 0;
- }
-
- The forward declaration for 'Foo' with the missing template type names
- 'A' and 'C' makes clang emit a bunch of template tags without names:
-
- ...
- <2><43>: Abbrev Number: 3 (DW_TAG_variable)
- <44> DW_AT_location : 2 byte block: 91 78 (DW_OP_fbreg: -8)
- <47> DW_AT_name : (indirect string, offset: 0x63): f
- <4b> DW_AT_decl_file : 1
- <4c> DW_AT_decl_line : 8
- <4d> DW_AT_type : <0x59>
- ...
- <1><59>: Abbrev Number: 5 (DW_TAG_class_type)
- <5a> DW_AT_calling_convention: 5 (pass by value)
- <5b> DW_AT_name : (indirect string, offset: 0x74): Foo<double, int, float>
- <5f> DW_AT_byte_size : 1
- <60> DW_AT_decl_file : 1
- <61> DW_AT_decl_line : 2
- <2><62>: Abbrev Number: 6 (DW_TAG_template_type_param)
- <63> DW_AT_type : <0x76>
- <2><67>: Abbrev Number: 7 (DW_TAG_template_type_param)
- <68> DW_AT_type : <0x52>
- <6c> DW_AT_name : (indirect string, offset: 0x6c): B
- <2><70>: Abbrev Number: 6 (DW_TAG_template_type_param)
- <71> DW_AT_type : <0x7d>
- ...
-
- Befor this patch, GDB would not create any symbols for the read template
- tag DIEs and thus lose knowledge about them. Breaking at the return
- statement and printing f's type would read
-
- (gdb) ptype f
- type = class Foo<double, int, float> [with B = int] {
- <no data fields>
- }
-
- After this patch GDB does generate symbols from the DWARF (with their
- artificial names:
-
- (gdb) ptype f
- type = class Foo<double, int, float> [with <unnamed0> = double, B = int,
- <unnamed1> = float] {
- <no data fields>
- }
-
- The same principle theoretically applies to template functions. Also
- here, GDB would not record unnamed template TAGs but I know of no visual
- way to trigger and test this changed behavior. Template functions do
- not emit a '[with...]' list and their name generation also does not
- suffer from template tags without names. GDB does not check whether or
- not a template tag has a name in 'dwarf2_compute_name' and thus, the
- names of the template functions are created independently of whether or
- not the template TAGs have a DW_TAT_name attribute. A testcase has
- been added in the gdb.dwarf2 for template classes and structs.

-
- gdb, testsuite: adapt function_range expected name
- When writing a dwarf testcase for some C++ code I wanted to use the
- MACRO_AT_range which in turn uses the function_range proc in dwarf.exp
- to extract the bounds of 'main'.
-
- However, the macro failed as GDB prints the C++ 'main' with its
- arguments as 'main(int, char**)' or 'main()'.
-
- The reason for this is that in read.c::dwarf2_compute_name we call
- c_type_print_args on C++ functions and append their arguments to the
- function name. This happens to all C++ functions, but is only visible
- when the function doesn't have a linkage name.
-
- An example might make this more clear. Given the following code
-
- >> cat c.cpp
- int foo (int a, float b)
- {
- return 0;
- }
-
- int main (int argc, char **argv)
- {
- return 0;
- }
-
- which is legal in both languages, C and C++, and compiling it with
- e.g. clang or gcc will make the disassemble command look like:
-
- >> clang --version
- clang version 10.0.0-4ubuntu1
- ...
- >> clang -O0 -g ./c.cpp
- >> gdb -q ./a.out -ex "start"
- ...
- (gdb) disassemble main
- Dump of assembler code for function main(int, char**):
- 0x0000000000401120 <+0>: push %rbp
- 0x0000000000401121 <+1>: mov %rsp,%rbp
- ...
- 0x0000000000401135 <+21>: ret
- End of assembler dump.
- (gdb) disassemble foo
- Dump of assembler code for function _Z3fooif:
- 0x0000000000401110 <+0>: push %rbp
- 0x0000000000401111 <+1>: mov %rsp,%rbp
- ...
- 0x000000000040111f <+15>: ret
- End of assembler dump.
-
- Note, that main is emitted with its arguments while for foo the linkage
- name is being printed, as also visible in its DWARF:
-
- >> objdump ./a.out --dwarf=info | grep "foo" -A3 -B3
- <2b> DW_AT_low_pc : 0x401110
- <33> DW_AT_high_pc : 0x10
- <37> DW_AT_frame_base : 1 byte block: 56 (DW_OP_reg6 (rbp))
- <39> DW_AT_linkage_name: (indirect string, offset: 0x39): _Z3fooif
- <3d> DW_AT_name : (indirect string, offset: 0x42): foo
- <41> DW_AT_decl_file : 1
- <42> DW_AT_decl_line : 1
- <43> DW_AT_type : <0x9a>
-
- Now, let's rename the C++ file and compile it as C:
-
- >> mv c.cpp c.c
- >> clang -O0 -g ./c.c
- >> gdb -q ./a.out -ex "start'
- ...
- (gdb) disassemble main
- Dump of assembler code for function main:
- 0x0000000000401120 <+0>: push %rbp
- 0x0000000000401121 <+1>: mov %rsp,%rbp
- ...
- 0x0000000000401135 <+21>: ret
- End of assembler dump.
- (gdb) disassemble foo
- Dump of assembler code for function foo:
- 0x0000000000401110 <+0>: push %rbp
- 0x0000000000401111 <+1>: mov %rsp,%rbp
- ...
- 0x000000000040111f <+15>: ret
- End of assembler dump.
-
- Note, for foo we did not get a linkage name emitted in DWARF, so
- it is printed by its name:
-
- >> objdump --dwarf=info ./a.out | grep foo -A3 -B3
- <2b> DW_AT_low_pc : 0x401110
- <33> DW_AT_high_pc : 0x10
- <37> DW_AT_frame_base : 1 byte block: 56 (DW_OP_reg6 (rbp))
- <39> DW_AT_name : (indirect string, offset: 0x37): foo
- <3d> DW_AT_decl_file : 1
- <3e> DW_AT_decl_line : 1
- <3f> DW_AT_prototyped : 1
-
- To make the macro and proc work with C++ as well, an optional argument
- list was added to the regex matching the function name in the
- disassemble command in function_range. This does not change any used
- behavior as currently, there exists no C++ test using the proc
- function_range.

- ld: pe: Fix linking against Microsoft import libraries with multiple DLLs
- Initially, since c6c37250e98f113755e0d787f7070e2ac80ce77e (in 1999),
- in order to fix linking against Microsoft import libraries, ld did
- internally rename members of such libraries. At that point, the
- criteria for being considered a Microsoft import library was that
- every archive member had the same name (no regard for exactly what
- that name was).
-
- This was later amended in 44dbf3639f127af46d569ad96b6242dfbc4c0a89
- (in 2003) to allow for Microsoft import libraries with intermixed
- static object files. At this point, the criteria were extended, so
- that all members following the first member named *.dll either had
- the exact same member name, or be named *.obj. (Curiously, this would
- allow members with any name if it precedes the first one named *.dll.)
-
- In practice, Microsoft style import libraries can contain
- members for linking against more than one DLL (built by merging
- multiple regular import libraries into one).
-
- Instead of trying to do validation of the whole archive before
- considering it a Microsoft style import library, relax the criteria
- for doing the member renaming: If an archive member is named *.dll
- and it contains .idata sections, assume that that member is a
- Microsoft import file, and apply the renaming scheme.
-
- This works for imports for any number of DLLs in the same library,
- intermixed with other static object files (regardless of their
- names), and vastly simplifies the code.
-
- LLVM generates Microsoft style import libraries, and Rust builds
- seem to bundle up multiple import libraries together with some
- Rust specific static objects. This fixes linking directly against
- them with ld.bfd.

- [gdb/symtab] Fix assert in set_length
- When running the included test-case, we run into:
- ...
- (gdb) break _start^M
- read.h:309: internal-error: set_length: \
- Assertion `m_length == length' failed.^M
- ...
-
- The problem is that while there are two CUs:
- ...
- $ readelf -wi debug-names-missing-cu | grep @
- Compilation Unit @ offset 0x0:
- Compilation Unit @ offset 0x2d:
- ...
- the CU table in the .debug_names section only contains the first one:
- ...
- CU table:
- [ 0] 0x0
- ...
-
- The incomplete CU table makes create_cus_from_debug_names_list set the size of
- the CU at 0x0 to the actual size of both CUs combined.
-
- This eventually leads to the assert, when we read the actual size from the CU
- header.
-
- While having an incomplete CU table in a .debug_names section is incorrect,
- we need a better failure mode than asserting.
-
- The easiest way to fix this is to set the length to 0 (meaning: unkown) in
- create_cus_from_debug_names_list.
-
- This makes the failure mode to accept the incomplete CU table, but to ignore
- the missing CU.
-
- It would be nice to instead reject the .debug_names index, and build a
- complete CU list, but the point where we find this out is well after
- dwarf2_initialize_objfile, so it looks rather intrusive to restart at that
- point.
-
- Tested on x86_64-linux.

- I tried out the script gdb/gdb_mbuild.sh, and ran into:
- ...
- score-elf ...
- ... configure --target=score-elf
- ... make score-elf
- ... run score-elf
- score-elf: gdb dumped core

- internal_error (__FILE__, __LINE__,
- _("initialize_current_architecture: Selection of "
- "initial architecture failed"));
- ...
-
- The call to gdbarch_update_p fails because commit 575b4c298a6 ("gdb: Remove
- support for S+core") removed support for the architecture.
-
- Fix this by adding score-*-* to the list of obsolete targets in
- gdb/configure.tgt, such that we're no longer able to build the configuration:
- ...
- *** Configuration score-unknown-elf is obsolete.
- *** Support has been REMOVED.

-
- Also remove the related line from the "Target Instruction Set Architectures"

- it.

- Allow to document user-defined aliases.
- Compared to the previous version, this version fixes the comments reported by
- Tom Tromey and ensures that the 'help some-user-documented-alias'
- shows the alias definition to ensure the user understands this is an
- alias even if specifically documented.
-
- When using 'help ALIASNAME', GDB shows the help of the aliased command.
- This is a good default behaviour.
-
- However, GDB alias command allows to define aliases with arguments
- possibly changing or tuning significantly the behaviour of
- the aliased command. In such a case, showing the help of the aliased
- command might not be ideal.
-
- This is particularly true when defining an alias as a set of
- nested 'with' followed by a last command to launch, such as:
- (gdb) alias pp10 = with print pretty -- with print elements 10 -- print
- Asking 'help pp10' shows the help of the 'with' command, which is
- not particularly useful:
- (gdb) help pp10
- with, pp10, w
- alias pp10 = with print pretty -- with print elements 10 -- print
- Temporarily set SETTING to VALUE, run COMMAND, and restore SETTING.
- Usage: with SETTING [VALUE] [-- COMMAND]
- ....
-
- Such an alias can now be documented by the user:
- (gdb) document pp10
- >Pretty printing an expressiong, printing 10 elements.
- >Usage: pp10 [PRINT-COMMAND-OPTIONS] EXP
- >See 'help print' for more information.
- >end
- (gdb) help pp10
- alias pp10 = with print pretty -- with print elements 10 -- print
- Pretty printing an expressiong, printing 10 elements.
- Usage: pp10 [PRINT-COMMAND-OPTIONS] EXP
- See 'help print' for more information.
- (gdb)
-
- When a user-defined alias is documented specifically, help and apropos
- use the provided alias documentation instead of the documentation of
- the aliased command.
-
- Such a documented alias is also not shown anymore in the help of the
- aliased command, and the alias is not listed anymore in the help
- of the aliased command. In particular for cases such as pp10 example above,
- indicating that pp10 is an alias of the 'with' command is confusing.

- x86: Ignore protected visibility in shared libraries on Solaris
- On x86, the PLT entry in executable may be used as function address for
- functions in shared libraries. If functions are protected, the function
- address used in executable can be different from the function address
- used in shared library. This will lead to incorrect run-time behavior
- if function pointer equality is needed. By default, x86 linker issues
- an error in this case.
-

- struct tm *tb = (kind == CPP_time_kind::FIXED ? gmtime : localtime) (&tt);

- where gmtime is a protected function in libc.so. Use gmtime's PLT entry

- ld: pe: Make archive member file extension comparisons case insensitive when cross compiling too
- On Windows, filename_cmp is case insensitive, but when cross compiling
- with libraries that may contain members with uppercase file names, we
- should keep those comparisons case insensitive when running the build
- tools on other OSes too.
-
- Also make the check for .def consistent with the other ones, fixing
- out of bounds reads if file names are shorter than 4 characters.

- gas: arm: handle multiple .directives on a single line (PR29519)
- There's been a long-standing bug in the arm backend where
- target-specific directives did not correctly handle lines with
- multiple statements. This patch fixes the issue for all the cases
- I've been able to find.
-
- It does result in a slight change in behaviour when errors are
- encountered: where, previously,
-
- .cpu arm6 bar
-
- would result in the error "junk at end of line, first unrecognized
- character is `b'", we now get "unknown cpu `arm6 bar'", which I think
- is slightly more helpful anyway. Similar errors are generated for
- other directives.

- gdb: new 'maint print frame-id' command
- When debugging a certain class of GDB bug, I often end up wanting to
- know what GDB thinks the frame-id is in a particular frame. It's
- not too hard to pull this from some debug output, but I thought it
- might be nice if there was a maintenance command that could tell us.
-
- This commit adds 'maint print frame-id' which prints the frame-id of
- the currently selected frame. You can also pass a frame level number
- to find the frame-id for a specific frame.
-
- There's a new test too.

- SHT_RELR sh_link and sh_info
- I don't think it makes any sense for a SHT_RELR section to specify a
- symbol table with sh_link. SHT_RELR relocations don't use symbols.
- There is no real need to specify sh_info either, SHT_RELR is not for
- relocatable object files. Anyway, fuzzers of course don't restrict
- themselves to even half-sensible objects. So they found a hole in
- objcopy using a non-alloc SHT_RELR in an ET_EXEC. In that case BFD
- set up the SHT_RELR section as if it were a SHT_REL against the
- sh_info target section. When it came to reading in the target section

- Implement target async for Windows
- This implements target async for Windows. The basic idea is to have
- the worker thread block in WaitForDebugEvent, then notify the event
- loop when an event is seen. In a few situations, this blocking

- Move some Windows operations to worker thread
- On Windows, certain debugging APIs can only be called from the thread
- that started (or attached) to the inferior. Also, there is no way on
- Windows to wait for a debug event in addition to other events.
- Therefore, in order to implement target async for Windows, gdb will

- symbols for bfd_simple_get_relocated_section_contents
- If symbols are provided by the caller of this function they are
- passed on to bfd_get_relocated_section_contents. No surprises there.
- It gets a little weird if they are not provided. In that case they
- are read from the bfd by _bfd_generic_link_add_symbols, and global
- symbols are added to the generic linker hash table. Global symbols
- are not added to the linker hash table if symbols *are* provided. Now
- the linker hash table symbols are not used by the generic
- bfd_get_relocated_section_conents, and also not by most target
- versions when called from bfd_simple_get_relocated_section_contents
- except for symbols like "_gp". So it mostly doesn't matter whether
- symbols are in the linker hash table, but it's odd that there is a
- difference. We could always add them, but I'm inclined to think that
- is unnecessary work so this patch always leaves them out.
-
- Also, symbols are canonicalized and written into a malloc'd buffer.
- The buffer isn't freed, see commit 8e16317ca5eb. I don't know whether
- that matters any more, but in any case I can't see why we need another
- copy of the symbols when _bfd_generic_link_read_symbols has already
- cached symbols.
-
- * simple.c (bfd_simple_get_relocated_section_contents): If not
- provided, read symbols via bfd_generic_link_read_symbols. Do
- not create another copy of symbols. Tidy failure exits.

- gdb/testsuite: re-compile entry-value-typedef .S files with -fPIE
- As Luis pointed out here [1], the AArch64 variant of the test doesn't
- work on systems that use PIE by default. For example, on this Debian
- 11:
-
- $ make check TESTS="gdb.dwarf2/entry-value-typedef.exp"
- gdb compile failed, /usr/bin/ld: /tmp/ccJE8ZSr.o: relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `_ZNSsD1Ev@@GLIBCXX_3.4' which may bind externally can not be used when making a shared object; recompile with -fPIC
- /usr/bin/ld: /tmp/ccJE8ZSr.o(.text+0x38): unresolvable R_AARCH64_ADR_PREL_PG_HI21 relocation against symbol `_ZNSsD1Ev@@GLIBCXX_3.4'
-
- This is because entry-value-typedef-aarch64.S was generated on an old
- system that does not generate position-independent code by default, but
- the system the test runs on tries to link the test executable as
- position-independent. Fix this by regenerating the same binary on the
- same system as the original one, but with -fPIE this time. Do the same
- for the amd64 binary, although this one was already position-independent
- so the generated code doesn't change.
-
- With this patch applied, the test passes on the Debian 11 AArch64
- system.

- The problem is that the type that gets passed down to
- dwarf_expr_context::fetch_result (the type of a variable of which we're
- trying to read the entry value) is a typedef whose size has never been
- computed yet (check_typedef has never been called on it). As we get in
- the DWARF_VALUE_STACK case (line 1028 of dwarf2/expr.c), the `len`
- variable is therefore set to 0, instead of the actual type length. We
- then call allocate_value on subobj_type, which does call check_typedef,
- so the length of the typedef gets filled in at that point. We end up
- passing to the copy function a source array view of length 0 and a
- target array view of length 4, and the assertion fails.
-
- Fix this by calling check_typedef on both type and subobj_type at the
- beginning of fetch_result.
-
- I tried writing a test for this using the DWARF assembler, but I haven't
- succeeded. It's possible that we need to get into this specific code
- path (value_of_dwarf_reg_entry and all) to manage to get to
- dwarf_expr_context::fetch_result with a typedef type that has never been
- resolved. In all my attempts, the typedef would always be resolved
- already, so the bug wouldn't show up.
-
- As a fallback, I made a gdb.dwarf2 test with compiler-generated .S
- files. I don't particularly like those, but I think it's better than no
- test. The .cpp source code is the smallest reproducer I am able to make
- from the reproducer given in the bug (thanks to Pedro for suggestions on
- how to minimize it further than I had). Since I tested on both amd64
- and aarch64, I added versions of the test for these two architectures.

- [aarch64] Remove handling of ADR/ADRP from prologue analyzer
- As reported by Tom in https://sourceware.org/pipermail/gdb-patches/2022-August/191357.html,
- the aarch64 prologue analyzer considers the adrp instruction in the
- gdb.dwarf2/dw2-dir-file-name.exp testcase to be part of a prologue.
-
- The function has no prologue though, and it only loads the volatile variable
- from memory. GDB should not skip any instructions in this case.
-
- Doing some archaeology, it seems handling for adr/adrp in prologues was
- included with the original aarch64 port. It might've been an oversight.
-
- In the particular case of gdb.dwarf2/dw2-dir-file-name.exp, the analyzer skips
- a couple instructions and leaves us in a nice spot where the address to the
- variable "v" is already in w0. But no prologues exists.

- Notice that register tpidr disappeared when vg (which holds the vector
- length) changed from 8 to 4. The tpidr register is provided by the
- org.gnu.gdb.aarch64.tls feature.
-
- This happens because the code that searches for a new gdbarch to match the
- new vector length in aarch64_linux_nat_target::thread_architecture doesn't
- take into account the features present in the target description associated

- gdbsupport/event-loop: add a timeout parameter to gdb_do_one_event
- Since commit b2d8657, having a per-interpreter event/command loop is not
- possible anymore.
-
- As Insight uses a GUI that has its own event loop, gdb and GUI event
- loops have then to be "merged" (i.e.: work together). But this is
- problematic as gdb_do_one_event is not aware of this alternate event
- loop and thus may wait forever.
-
- A solution is to delegate GUI events handling to the gdb events handler.
- Insight uses Tck/Tk as GUI and the latter offers a "notifier" feature to
- implement such a delegation. The Tcl notifier spec requires the event wait
- function to support a timeout parameter. Unfortunately gdb_do_one_event
- does not feature such a parameter.
- This timeout cannot be implemented externally with a gdb timer, because
- it would become an event by itself and thus can cause a legitimate event to
- be missed if the timeout is 0.
- Tcl implements "idle events" that are (internally) triggered only when no
- other event is pending. For this reason, it can call the event wait function
- with a 0 timeout quite often.
-
- This patch implements a wait timeout to gdb_do_one_event. The initial
- pending events monitoring is performed as before without the possibility
- to enter a wait state. If no pending event has been found during this
- phase, a timer is then created for the given timeout in order to re-use
- the implemented timeout logic and the event wait is then performed.
- This "internal" timer only limits the wait time and should never be triggered.
- It is deleted upon gdb_do_one_event exit.
-
- The new parameter defaults to "no timeout" (-1): as it is used by Insight
- only, there is no need to update calls from the gdb source tree.

- x86: move / quiesce pre-386 non-16-bit warning
- Emitting this warning for every insn, including ones having actual

- just once on the first insn after .arch may have changed the things, and
- move the warning to output_insn(). (I didn't want to go as far as

- gdb/riscv: fix gdb.arch/riscv-unwind-long-insn.exp on RV64
- I noticed that the gdb.arch/riscv-unwind-long-insn.exp test was
- failing when run on a 64-bit RISC-V target.
-
- The problem was that GDB was failing to stop after a finish command,
- and was then running to an unexpected location.
-
- The reason GDB failed to stop at the finish breakpoint was that the
- frame-id of the inferior, when we reached the finish breakpoint,
- didn't match the expected frame-id that was stored on the breakpoint.
-
- The reason for this mismatch was that the assembler code that is
- included in this test, was written only taking 32-bit RISC-V into
- account, as a result, the $fp register was being corrupted, and this
- was causing the frame-id mismatch.
-
- Specifically, the $fp register would end up being sign-extended from
- 32 to 64 bits. If the expected $fp value has some significant bits
- above bit 31 then the computed and expected frame-ids would not match.
-
- To fix this I propose merging the two .s files into a single .S file,
- and making use of preprocessor macros to specialise the file for the
- correct size of $fp. There are plenty of existing tests that already
- make use of preprocessor macros in assembler files, so I assume this
- approach is fine.
-
- Once I'd decided to make use of preprocessor macros to solve the 32/64
- bit issue, then I figured I might as well merge the two test assembler
- files, they only differed by a single instruction.
-
- With this change in place I now see this test fully passing on 32 and
- 64 bit RISC-V targets.

- PR29495, rewrite_elf_program_header looping
- This patch, in order of significance:
- 1) Replaces some macros with inline functions.
- 2) Those inline functions catch and avoid arithmetic overflows when
- comparing addresses.
- 3) When assigning sections to segments (IS_SECTION_IN_INPUT_SEGMENT)
- use bed->want_p_paddr_set_to_zero to decide whether lma vs p_paddr
- or vma vs p_vaddr should be tested. When remapping, use the same
- test, and use is_note rather than the more restrictive
- IS_COREFILE_NOTE.
-
- It's important that the later tests not be more restrictive. If they
- are it can lead to the situation triggered by the testcases, where a
- section seemingly didn't fit and thus needed a new mapping. It didn't
- fit the new mapping either, and this repeated until memory exhausted.

- gdb/riscv: improve a comment about fcsr, fflags, and frm registers
- There's a comment in riscv-tdep.c that explains some of the background
- about how we check for the fcsr, fflags, and frm registers within a
- riscv target description.
-
- This comment (and the functionality it describes) relates to how QEMU
- advertises these registers within its target description.
-
- Unfortunately, QEMU includes these three registers in both the fpu and
- crs target description features. To work around this GDB uses one of
- the register declarations, and ignores the other, this means the GDB
- user sees a single copy of each register, and things just work.
-
- When I originally wrote the comment I thought it didn't matter which
- copy of the register GDB selected, the fpu copy or the csr copy, so
- long as we just used one of them. The comment reflected this belief.
-
- Upon further investigation, it turns out I was wrong. GDB has to use
- the csr copy of the register. If GDB tries to use the register from
- the fpu feature then QEMU will return an error when GDB tries to read
- or write the register.
-
- Luckily, the code within GDB (currently) will always select the csr
- copy of the register, so nothing is broken, but the comment is wrong.
- This commit updates the comment to better describe what is actually
- going on.
-
- Of course, I should probably also send a patch to QEMU to fix up the
- target description that is sent to GDB.

-
- Don't use bfd_size_type in readelf.c and dwarf.c
- Replacing bfd_size_type with dwarf_size_type or uint64_t is mostly

- [gdb/testsuite] Fix gdb.dwarf2/dw2-dir-file-name.exp
- When running test-case gdb.dwarf2/dw2-dir-file-name.exp on x86_64-linux, we
- have:
- ...
- (gdb) break compdir_missing__ldir_missing__file_basename^M
- Breakpoint 2 at 0x4004c4: file tmp-dw2-dir-file-name.c, line 999.^M
- (gdb) continue^M
- Continuing.^M
- ^M
- Breakpoint 2, 0x00000000004004c4 in \
- compdir_missing__ldir_missing__file_basename () \
- at tmp-dw2-dir-file-name.c:999^M
- (gdb) PASS: gdb.dwarf2/dw2-dir-file-name.exp: \
- compdir_missing__ldir_missing__file_basename: continue to breakpoint: \
- compdir_missing__ldir_missing__file_basename
- ...
-
- When trying to set a breakpoint on
- compdir_missing__ldir_missing__file_basename, the architecture-specific
- prologue skipper starts at 0x4004c0 and skips past two insns, to 0x4004c4:
- ...
- 00000000004004c0 <compdir_missing__ldir_missing__file_basename>:
- 4004c0: 55 push %rbp
- 4004c1: 48 89 e5 mov %rsp,%rbp
- 4004c4: 8b 05 72 1b 20 00 mov 0x201b72(%rip),%eax # 60203c <v>
- 4004ca: 83 c0 01 add $0x1,%eax
- 4004cd: 89 05 69 1b 20 00 mov %eax,0x201b69(%rip) # 60203c <v>
- 4004d3: 90 nop
- 4004d4: 5d pop %rbp
- 4004d5: c3 ret
- ...
-
- And because the line table info is rudamentary:
- ...
- CU: tmp-dw2-dir-file-name.c:
- File name Line number Starting address View Stmt
- tmp-dw2-dir-file-name.c 999 0x4004c0 x
- tmp-dw2-dir-file-name.c 1000 0x4004d6 x
- tmp-dw2-dir-file-name.c - 0x4004d6
- ...
- the address does not fall at an actual line, so the breakpoint is shown with
- address, both when setting it and hitting it.
-
- when running the test-case with aarch64-linux, we have similarly:
- ...
- (gdb) break compdir_missing__ldir_missing__file_basename^M
- Breakpoint 2 at 0x400618: file tmp-dw2-dir-file-name.c, line 999.^M
- ...
- due to the architecture-specific prologue skipper starting at 0x400610 and
- skipping past two insns, to 0x400618:
- ...
- 0000000000400610 <compdir_missing__ldir_missing__file_basename>:
- 400610: 90000100 adrp x0, 420000 <__libc_start_main@GLIBC_2.17>
- 400614: 9100b000 add x0, x0, #0x2c
- 400618: b9400000 ldr w0, [x0]
- 40061c: 11000401 add w1, w0, #0x1
- 400620: 90000100 adrp x0, 420000 <__libc_start_main@GLIBC_2.17>
- 400624: 9100b000 add x0, x0, #0x2c
- 400628: b9000001 str w1, [x0]
- 40062c: d503201f nop
- 400630: d65f03c0 ret
- ...
-
- But interestingly, the aarch64 architecture-specific prologue skipper is
- wrong. There is no prologue, and the breakpoint should be set at 0x400610.
-
- By using "break *compdir_missing__ldir_missing__file_basename"
- we can get the breakpoint set at 0x400610:
- ...
- (gdb) break *compdir_missing__ldir_missing__file_basename^M
- Breakpoint 2 at 0x400610: file tmp-dw2-dir-file-name.c, line 999.^M
- ...
- and make the test-case independent of prologue analysis.
-
- This requires us to update the expected patterns.
-
- The fix ensures that once the aarch64 architecture-specific prologue skipper
- will be fixed, this test-case won't start failing.
-
- Tested on x86_64-linux.

- gdb/varobj: Only re-evaluate invalid globals during re_set
- When doing varobj_re_set, we currently try to recreate floating varobj.
- This was introduced by 4e969b4f0128 "Re-evaluate floating varobj as part
- of varobj_invalidate" to deal with use a after free issue. However
- since bc20e562ec0 "Fix use after free in varobj" we now ensure that we
- never have dangling pointers so this all recreation is not strictly
- needed anymore for floating varobjs.
-
- This commit proposes to remove this recreation process for floating
- varobjs.

- Tested on x86_64-linux.

- gdb/varobj: Reset varobj after relocations have been computed
- [This patch is a followup to the discussion in
- https://sourceware.org/pipermail/gdb-patches/2022-August/191188.html]
-
- PR/29426 shows failures when running the gdb.mi/mi-var-invalidate-shlib
- test when using a compiler which does not produce a PIE executable by
- default.
-
- In the testcase, a varobj is created to track a global variable, and
- then the main binary is reloaded in GDB (using the file command).
-
- During the load of the new binary, GDB tries to recreate the varobj to
- track the global in the new binary (varobj_invalidate_iter). At this
- point, the old process is still in flight. So when we try to access to
- the value of the global, in a PIE executable we only have access to the
- unrelocated address (the objfile's text_section_offset () is 0). As a
- consequence down the line read_value_memory fails to read the unrelated
- address, so cannot evaluate the value of the global. Note that the
- expression used to access to the global’s value is valid, so the varobj
- can be created. When using a non PIE executable, the address of the
- global GDB knows about at this point does not need relocation, so
- read_value_memory can access the (old binary’s) value.
-
- So at this point, in the case of a non-PIE executable the value field is
- set, while it is cleared in the case of PIE executable. Later when the
- test issues a "-var-update global_var", the command sees no change in
- the case of the non-PIE executable, while in the case of the PIE
- executable install_new_value sees that value changes, leading to a
- different output.
-
- This patch makes sure that, as we do for breakpoints, we wait until
- relocation has happened before we try to recreate varobjs. This way we
- have a consistent behavior between PIE and non-PIE binaries.
-
- Tested on x86_64-linux.

- gdb/varobj: Do not invalidate locals in varobj_invalidate_iter
- The varobj_invalidate_iter function has logic to invalidate any local
- varobj it can find. However since bc20e562ec0 "gdb/varobj: Fix use
- after free in varobj" all varobj containing references to an objfile are
- cleared when the objfile goes out of scope. This means that at this
- point any local varobj seen by varobj_invalidate_iter either has
- already been invalidated by varobj_invalidate_if_uses_objfile or only
- contains valid references and there is no reason to invalidate it.
-
- This patch proposes to remove this unnecessary invalidation and adds a
- testcase which exercises a scenario where a local varobj can legitimately
- survive a call to varobj_invalidate_iter.
-
- At this point the varobj_invalidate and varobj_invalidate_iter seem
- misnamed since they deal with re-creating invalid objects and do not do
- invalidation, but this will be fixed in a following patch.
-
- Tested on x86_64-linux.

- PR29466, APP/NO_APP with .linefile
- Commit 53f2b36a54b9 exposed a bug in sb_scrub_and_add_sb that could
- result in losing input. If scrubbing results in expansion past the
- holding capacity of do_scrub_chars output buffer, then do_scrub_chars
- stashes the extra input for the next call. That call never came
- because sb_scrub_and_add_sb wrongly decided it was done. Fix that by
- allowing sb_scrub_and_add_sb to see whether there is pending input.
- Also allow a little extra space so that in most cases we won't need
- to resize the output buffer.
-
- sb_scrub_and_add_sb also limited output to the size of the input,
- rather than the actual output buffer size. Fixing that resulted in a
- fail of gas/testsuite/macros/dot with an extra warning: "end of file
- not at end of a line; newline inserted". OK, so the macro in dot.s
- really does finish without end-of-line. Apparently the macro
- expansion code relied on do_scrub_chars returning early. So fix that
- too by adding a newline if needed in macro_expand_body.

- (gdb)
-
- In both the =breakpoint-modified and -break-info output, we have:
-
- script={"aaa","bbb","ccc"}
-
- According to the output syntax [1], curly braces means tuple, and a
- tuple contains key=value pairs. This looks like it should be a list,
- but uses curly braces by mistake. This would make more sense:
-
- script=["aaa","bbb","ccc"]
-
- Fix it, keeping the backwards compatibility by introducing a new MI
- version (MI4), in exactly the same way as was done when fixing
- multi-locations breakpoint output in [2].
-
- - Add a fix_breakpoint_script_output uiout flag. MI uiouts will use
- this flag if the version is >= 4.
- - Add a fix_breakpoint_script_output_globally variable and the
- -fix-breakpoint-script-output MI command to set it, if frontends want
- to use the fixed output for this without using the newer MI version.
- - When emitting the script field, use list instead of tuple, if we want
- the fixed output (depending on the two criteria above)

- Disable year 2038 support on 32-bit hosts by default
- With a recent import of gnulib, code has been pulled that tests and enables
- 64-bit time_t by default on 32-bit hosts that support it.
-
- Although gdb can use the gnulib support, bfd doesn't use gnulib and currently
- doesn't do these checks.
-
- As a consequence, if we have a 32-bit host that supports 64-bit time_t, we'll
- have a mismatch between gdb's notion of time_t and bfd's notion of time_t.
-
- This will lead to mismatches in the struct stat size, leading to memory
- corruption and crashes.
-
- This patch disables the year 2038 check for now, which makes things work
- reliably again.
-
- I'd consider this a temporary fix until we have proper bfd checks for the year
- 2038, if it makes sense. 64-bit hosts seems to be more common these days, so
- I'm not sure how important it is to have this support enabled and how soon
- we want to enable it.

- gas/Dwarf: properly skip zero-size functions
- PR gas/29451
-
- While out_debug_abbrev() properly skips such functions, out_debug_info()
- mistakenly didn't. It needs to calculate the high_pc expression ahead of
- time, in order to skip emitting any data for the function if the value
- is zero.
-
- The one case which would still leave a zero-size entry is when

- expect that to not be the case, otherwise we'd need to have a way to

- This means that this target does not support relocation processing and is mostly

- gdb/riscv/testsuite: fix failures in gdb.arch/riscv-reg-aliases.exp
- When running on a native RISC-V Linux target I currently see failures
- in the gdb.arch/riscv-reg-aliases.exp test like this:
-
- set $ft0.float = 501
- (gdb) PASS: gdb.arch/riscv-reg-aliases.exp: write non-zero value to ft0
- p/d $ft0.float
- $263 = 1140490240
- (gdb) FAIL: gdb.arch/riscv-reg-aliases.exp: read ft0 after non-zero write to ft0
-
- This test started failing after this commit:
-
- commit 56262a931b7ca8ee3ec9104bc7e9e0b40cf3d64e
- Date: Thu Feb 17 13:43:59 2022 -0700
-
- Change how "print/x" displays floating-point value
-
- The problem is that when 501 is written to $ft0.float the value is
- converted to floating point format and stored in the register. Prior
- to the above commit printing with /x and /d would first extract the
- value as a float, and then convert the value to an integer for
- display. After the above commit GDB now uses the raw register value
- when displaying /x and /d, and so we see this behaviour:
-
- (gdb) info registers $ft0
- ft0 {float = 501, double = 5.6347704700123827e-315} (raw 0x0000000043fa8000)
- (gdb) p/f $ft0.float
- $1 = 501
- (gdb) p/d $ft0.float
- $2 = 1140490240
- (gdb) p/x $ft0.float
- $3 = 0x43fa8000
-
- To fix this test I now print the float registers using the /f format
- rather than /d. With this change the test now passes.

-
- When we create a pthread debug session we have callbacks to read

-
- Before we come into aix-thread wait() we switch to no thread and

- x86-64: adjust MOVQ to/from SReg attributes
- It is unclear to me why the corresponding MOV (no Q suffix) can be
- issued without REX.W, but MOVQ has to have that prefix (bit). Add
- NoRex64 and in exchange drop Size64.
-
- x86: adjust MOVSD attributes
- The non-SSE2AVX form of the SIMD variant of the instruction needlessly
- has the (still multi-purpose) IgnoreSize attribute. All other similar
- SSE2 insns use NoRex64 instead. Make this consistent, noting that the
- SSE2AVX form can't have the same change made - there the memory operand
- doesn't at the same time permit RegXMM (which logic uses when deciding
- whether a Q suffix is okay outside of 64-bit mode).
-
- x86: fold AVX VGATHERDPD / VPGATHERDQ
- While the other three variants each differ in attributes and hence can't
- be folded, these two pairs actually can be (and were previously
- overlooked). This effectively matches their AVX512VL counterparts, which
- are also expressed as a single template.
-
- x86: allow use of broadcast with X/Y/Z-suffixed AVX512-FP16 insns
- While the x/y/z suffix isn't necessary to use in this case, it is still
- odd that these forms don't support broadcast (unlike their AVX512F /
- AVX512DQ counterparts). The lack thereof can e.g. make macro-ized
- programming more difficult.
-
- x86/Intel: split certain AVX512-FP16 VCVT*2PH templates
- One more place where pre-existing templates should have been taken as a
- basis: In Intel syntax we want to consistently issue an "ambiguous
- operand size" error when a size-less memory operand is specified for an
- insn where register use alone isn't sufficient for disambiguation.

- [gdb/testsuite] Add support for .debug_names in dwarf assembler
- Add:
- - support for a per-module .debug_names section in the dwarf assembler, and
- - a test-case excercising this new functionality.
-
- A per-module .debug_names section needs to have an entry in the CU list for
- each CU in the module, which is made more difficult by two things:
- - linking in other objects, which may contain additional CUs
- (typically the case on openSUSE), and
- - adding dummy CUs in the dwarf assembler.
- We handle this by:
- - compiling with -nostartfiles (so the test-case contains _start rather than
- main), and
- - disabling the dummy CU generation for the test-case.
-
- I've kept things simple by having the test-case specify the hash value, rather
- than adding that functionality in the dwarf assembler.
-
- Also I've kept the bucket count to 1, which makes it trivial to satisfy the
- requirement that "the symbol is entered into a bucket whose index is the hash
- value modulo bucket_count".
-
- The readelf dump of the .debug_names section from the test-case looks like:
- ...
- Version 5
- Augmentation string: 47 44 42 00 ("GDB")
- CU table:
- [ 0] 0x0
-
- TU table:
-
- Foreign TU table:
-
- Used 1 of 1 bucket.
- Out of 2 items there are 1 bucket clashes (longest of 1 entries).
-
- Symbol table:
- [ 0] #eddb6232 _start: <1> DW_TAG_subprogram DW_IDX_compile_unit=0
- [ 1] #0b888030 int: <2> DW_TAG_base_type DW_IDX_compile_unit=0

- [gdb] Add unit test for gdb::sequential_for_each
- With commit 18a5766d09c ("[gdbsupport] Add sequential_for_each") I added a
- drop-in replacement for gdb::parallel_for_each, but there's nothing making
- sure that the two remain in sync.

- [gdb/symtab] Use task size in parallel_for_each in dwarf2_build_psymtabs_hard
- In dwarf2_build_psymtabs_hard, we use a parallel_for_each to distribute CUs
- over threads.
-
- Ensuring a fair distribution over the worker threads and main thread in terms
- of number of CUs might not be the most efficient way, given that CUs can vary
- in size.
-
- Fix this by using per_cu->get_length () as the task size.
-
- I've used this experiment to verify the performance impact:
- ...
- $ for n in $(seq 1 10); do \
- time gdb -q -batch ~/firefox/libxul.so-93.0-1.1.x86_64.debug \
- 2>&1 \
- | grep "real:"; \
- done
- ...
- and without the patch got:
- ...
- real: 4.71
- real: 4.88
- real: 4.29
- real: 4.30
- real: 4.65
- real: 4.27
- real: 4.27
- real: 4.27
- real: 4.75
- real: 4.41

- real: 3.69
- real: 3.69
- real: 3.74
- real: 3.67
- real: 3.74
- ...
- so that seems a reasonable improvement.
-
- With parallel_for_each_debug set to true, we get some more detail about
- the difference in behaviour. Without the patch we have:

-
- Introduce gdb::make_function_view
- This adds gdb::make_function_view, which lets you create a function
- view from a callable without specifying the function_view's template
- parameter. For example, this:
-
- auto lambda = [&] (int) { ... };
- auto fv = gdb::make_function_view (lambda);
-
- instead of:
-
- auto lambda = [&] (int) { ... };
- gdb::function_view<void (int)> fv = lambda;
-
- It is particularly useful if you have a template function with an
- optional function_view parameter, whose type depends on the function's
- template parameters. Like:
-
- template<typename T>
- void my_function (T v, gdb::function_view<void(T)> callback = nullptr);
-
- For such a function, the type of the callback argument you pass must
- already be a function_view. I.e., this wouldn't compile:
-
- auto lambda = [&] (int) { ... };
- my_function (1, lambda);
-
- With gdb::make_function_view, you can write the call like so:
-
- auto lambda = [&] (int) { ... };
- my_function (1, gdb::make_function_view (lambda));
-
- Unit tests included.
-
- Tested by building with GCC 9.4, Clang 10, and GCC 4.8.5, on x86_64
- GNU/Linux, and running the unit tests.

- Use registry in gdbarch
- gdbarch implements its own registry-like approach. This patch changes
- it to instead use registry.h. It's a rather large patch but largely
- uninteresting -- it's mostly a straightforward conversion from the old
- approach to the new one.
-
- The main benefit of this change is that it introduces type safety to
- the gdbarch registry. It also removes a bunch of code.
-
- One possible drawback is that, previously, the gdbarch registry
- differentiated between pre- and post-initialization setup. This
- doesn't seem very important to me, though.

- [gdb/testsuite] Fix ERROR in gdb.base/watchpoint-unaligned.exp
- In PR23888 an error is reported:
- ...
- ERROR: tcl error sourcing watchpoint-unaligned.exp.
- ERROR: expected boolean value but got ""
- while executing
- "if {$wpnum} {
- ...
-
- This presumably happens when:
- - skip_hw_watchpoint_tests returns 0 meaning hw watchpoints are supported
- - gdb fails to set a hw watchpoint and instead sets a sw watchpoint
-
- That particular situation is handled for arm:
- ...
- -re "Watchpoint (\[0-9\]+): .*\r\n$gdb_prompt $" {
- if {[istarget "arm*-*-*"]} {
- untested $test
- set wpnum 0
- }
- }
- ...
- but not for any other targets so wpnum remains "", triggering the ERROR.
-
- Possibly this has been fixed for powerpc by commit 8d4e4d13afb ("gdb Power 9
- add test for HW watchpoint support."), but it's still possible for other
- targets.
-
- Fix this by:
- - initializing wpnum to 0 instead of ""
- - signalling the failure to set a hw watchpoint by a fail
-
- Tested on x86_64-linux, also by adding:
- ...
- gdb_test_no_output "set can-use-hw-watchpoints 0"

- ...
- FAIL: gdb.base/large-frame.exp: optimize=-O0: backtrace

- The problem is that the architecture-specific prologue analyzer fails to

- 0000000000400610 <func>:
- 400610: d2880210 mov x16, #0x4010

- 400624: 97fffff0 bl 4005e4 <blah>
- ...
- so we get:
- ...
- $ gdb -q -batch ./outputs/gdb.base/large-frame/large-frame-O0 -ex "b func"
- Breakpoint 1 at 0x400614
- ...
-
- Fix this by:
- - fixing the support for the first insn to extract the immediate operand, and
- - adding support for the second insn,
- such that we have:
- ...
- Breakpoint 1 at 0x400624
- ...
- Note that we're overshooting by one insn (0x400620 is the first insn after the
- prologue), but that's a pre-existing problem.

- Don't use BFD_VMA_FMT in binutils

- So just get rid of BFD_VMA_FMT, instead using the appropriate PRId64,
- PRIu64, PRIx64 or PRIo64 and SCN variants for scanf. The patch is
- mostly mechanical, the only thing requiring any thought is casts

- Re: Get rid of fprintf_vma and sprintf_vma
- Commit f493c2174e messed the formatting in linker map files,
- particularly for 32-bit builds where a number of tests using map files
- regressed. I should have noticed the BFD64 conditional printing of
- spaces to line up output due to the original %V printing hex vmas with
- 16 digits when BFD64 and 8 digits when not. Besides that, it is nicer
- to print 32-bit vmas for 32-bit targets. So change %V back to be
- target dependent, now using bfd_sprintf_vma. Since minfo doesn't
- return the number of chars printed, that means some places that
- currently use %V must instead sprintf to a buffer in order to find the
- length printed.

- Use unique_ptr to destroy per-bfd object
- In some cases, the objfile owns the per-bfd object. This is yet
- another object that can sometimes be destroyed before the registry is
- destroyed, possibly reslting in a use-after-free. Also, I noticed
- that the condition for deleting the object is not the same as the
- condition used to create it -- so it could possibly result in a memory
- leak in some situations. This patch fixes the problem by introducing
- a new unique_ptr that holds this object when necessary.
-
- Use auto_obstack in objfile
- This changes objfile to use an auto_obstack. This helps prevent
- use-after-free bugs, because it ensures that anything allocated on the
- objfile obstack will live past the point at which the registry object
- is destroyed.
-
- Use gdb_bfd_ref_ptr in objfile
- This changes struct objfile to use a gdb_bfd_ref_ptr. In addition to
- removing some manual memory management, this fixes a use-after-free
- that was introduced by the registry rewrite series. The issue there
- was that, in some cases, registry shutdown could refer to memory that
- had already been freed. This help fix the bug by delaying the
- destruction of the BFD reference (and thus the per-bfd object) until
- after the registry has been shut down.

- gdb: Fix regression in varobj recreation
- Commit bc20e562ec0 "Fix use after free in varobj" introduced a
- regression. This commit makes sure that the varobj object does not
- keeps stale references to object being freed when we unload an objfile.
- This includes the "valid_block" field which is reset to nullptr if the
- pointed to block is tied to an objfile being freed.
-
- However, at some point varobj_invalidate_iter might try to recreate
- varobjs tracking either floating or globals. Varobj tracking globals
- are identified as having the "valid_block" field set nullptr, but as
- bc20e562ec0 might clear this field, we have lost the ability to
- distinguish between varobj referring to globals and non globals.
-
- Fix this by introducing a "global" flag which tracks if a given varobj
- was initially created as tracking a global.

- fbsd-nat: Correct the return type of the have_regset method.
- During the development of 40c23d880386d6e8202567eaa2a6b041feb1a652,
- the return value of fbsd_nat_target::have_regset was changed from a

- comments and callers were all updated for this change, but the actual
- return type was accidentally left as a bool. This change fixes the

- ld: aarch64: Adjust TLS relaxation condition
- In aarch64_tls_transition_without_check and elfNN_aarch64_tls_relax we
- choose whether to perform a relaxation to an IE access model or an LE
- access model based on whether the symbol itself is marked as local (i.e.
- `h == NULL`).
-
- This is problematic in two ways. The first is that sometimes a global
- dynamic access can be relaxed to an initial exec access when creating a
- shared library, and if that happens on a local symbol then we currently
- relax it to a local exec access instead. This usually does not happen
- since we only relax an access if aarch64_can_relax_tls returns true and
- aarch64_can_relax_tls does not have the same problem. However, it can
- happen when we have seen both an IE and GD access on the same symbol.
- This case is exercised in the newly added testcase tls-relax-gd-ie-2.
-
- The second problem is that deciding based on whether the symbol is local
- misses the case when the symbol is global but is still non-interposable
- and known to be located in the executable. This happens on all global
- symbols in executables.
- This case is exercised in the newly added testcase tls-relax-ie-le-4.
-
- Here we adjust the condition we base our relaxation on so that we relax
- to local-exec if we are creating an executable and the relevant symbol
- we're accessing is stored inside that executable.
-
- -- Updating tests for new relaxation criteria
-
- Many of the tests added to check our relaxation to IE were implemented
- by taking advantage of the fact that we did not relax a global symbol
- defined in an executable.
-
- Since a global symbol defined in an executable is still not
- interposable, we know that a TLS version of such a symbol will be in the
- main TLS block. This means that we can perform a stronger relaxation on
- such symbols and relax their accesses to a local-exec access.
-
- Hence we have to update all tests that relied on the older suboptimal
- decision making.
-
- The two cases when we still would want to relax a general dynamic access
- to an initial exec one are:
- 1) When in a shared library and accessing a symbol which we have already
- seen accessed with an initial exec access sequence.
- 2) When in an executable and accessing a symbol defined in a shared
- library.
-
- Both of these require shared library support, which means that these
- tests are now only available on targets with that.
-
- I have chosen to switch the existing testcases from a plain executable
- to one dynamically linked to a shared object as that doesn't require
- changing the testcases quite so much (just requires accessing a
- different variable rather than requiring adding another code sequence).
-
- The tls-relax-all testcase was an outlier to the above approach, since
- it included a general dynamic access to both a local and global symbol
- and inspected for the difference accordingly.

- arm: Use DWARF numbering convention for pseudo-register representation
- This patch modifies the internal `struct reg_entry' numbering of DWARF
- pseudo-registers to match values assigned in DWARF standards (see "4.1
- DWARF register names" in [1])so ra_auth_code goes from 12 to 143 and
- amends the unwinder .save directive-processing code to correctly handle
- mixed register-type save directives.
-
- The mechanism for splitting the register list is also re-written to
- comply with register ordering on push statements, being that registers
- are stored on the stack in numerical order, with the lowest numbered
- register at the lowest address [2].
-
- Consequently, the parsing of the hypothetical directive
-
- .save{r4-r7, r10, ra_auth_core, lr}
-
- has been changed such as rather than producing
-
- .save{r4-r7, r10}
- .save{ra_auth_code}
- .save{lr}
-
- as was the case with previous implementation, now produces:
-
- .save{lr}

- [gdb/symtab] Fix .debug_aranges duplicate offset warning
- The function read_addrmap_from_aranges contains code to issue a warning:
- ...
- if (!insertpair.second)
- {
- warning (_("Section .debug_aranges in %s has duplicate "
- "debug_info_offset %s, ignoring .debug_aranges."),
- objfile_name (objfile), sect_offset_str (per_cu->sect_off));
- return false;
- }
- ...
- but the warning is in fact activated when all_comp_units has duplicate
- entries, which is very misleading.
-
- Fix this by:
- - adding a test-case that should trigger the warning,
- - replacing the current implementation of the warning with an
- assert that all_comp_units should not contain duplicates, and
- - properly re-implementing the warning, such that it is triggered
- by the test-case.

- (gdb) print 16#ffffffffffffffff#^M
- $7 = -1^M
- (gdb) PASS: gdb.ada/literals.exp: print 16#ffffffffffffffff#

-
- We can easily reproduce this on x86_64-linux using:
- ...
- $ gdb -q -batch -ex "set lang ada" -ex "set arch i386" \
- -ex "print 16#ffffffffffffffff#"
- $1 = -1
- $ gdb -q -batch -ex "set lang ada" -ex "set arch aarch64" \
- -ex "print 16#ffffffffffffffff#"
- $1 = 18446744073709551615
- ...
-
- With i386, we have:
- ...
- (gdb) p int_bits
- $3 = 32
- (gdb) p long_bits
- $4 = 32
- (gdb) p long_long_bits
- $5 = 64
- ...
- and so in processInt we hit the fits-in-unsigned-long-long case where we use
- as type long long:
- ...
- /* Note: Interprets ULLONG_MAX as -1. */
- yylval.typed_val.type = type_long_long (par_state);
- ...
-
- With aarch64, we have instead:
- ...
- (gdb) p int_bits
- $1 = 32
- (gdb) p long_bits
- $2 = 64
- (gdb) p long_long_bits
- $3 = 64
- ...
- and so in processInt we hit the fits-in-unsigned-long case where we use
- as type unsigned long:
- ...
- yylval.typed_val.type
- = builtin_type (par_state->gdbarch ())->builtin_unsigned_long;
- ...
-
- It's not clear why for ada we're using long long for the
- fits-in-unsigned-long-long case.
-
- Fix this by using unsigned long long for the fits-in-unsigned-long-long case,
- meaning the new reference output is 18446744073709551615 instead of -1.

- gdb/testsuite: add macros test for source files compiled in various ways
- Using different ways of passing source file paths to compilers results n
- different file and directory paths in the line header. For example:
-
- - gcc foo.c
- - gcc ./foo.c
- - gcc ../cwd/foo.c
- - gcc $PWD/foo.c
-
- Because of this, GDB sometimes failed to look up macros. The previous
- patch fixed that as much as possible. This patch adds the corresponding
- tests.
-
- Add both a DWARF assembler-based test and a regular test. The DWARF
- assembled-based one tests some hard-coded debug info based on what I
- have observed some specific versions of gcc and clang generate. We want
- to make sure that GDB keeps handling all these cases correctly, even if
- it's not always clear whether they are really valid DWARF. Also, they
- will be tested no matter what the current target compiler is for a given
- test run.
-
- The regular test is compiled using the target compiler, so it may help
- find bugs when testing against some other toolchains than what was used
- to generate the DWARF assembler-based test.
-
- For the DWARF assembler-based test, add to testsuite/lib/dwarf.exp the
- necessary code to generate a DWARF5 .debug_macro section. The design of
- the new procs is based on what was done for rnglists and loclists.
-
- To test against a specific compiler one can use this command, for
- example:
-
- $ make check TESTS="gdb.base/macro-source-path.exp" RUNTESTFLAGS="CC_FOR_TARGET=clang --target_board unix/gdb:debug_flags=-gdwarf-5"

- gdb: remove code to prepend comp dir in buildsym_compunit::start_subfile
- The bit of code removed by this patch was introduced to fix the same
- kind of problem that the previous patch fixes. That is, to try to match
- existing subfiles when different name forms are used to refer to a same
- file.
-
- The thread for the patch that introduced this code is:
-
- https://pi.simark.ca/gdb-patches/45F8CBDF.9090501@hq.tensilica.com/
-
- The important bits are that the compiler produced a compilation unit
- with:
-
- DW_AT_name : test.c
- DW_AT_comp_dir : /home/maxim/W/BadgerPass/PR_14999
-
- and DWARF v2 line table with:
-
- The Directory Table:
- /home/maxim/W/BadgerPass/PR_14999
-
- The File Name Table:
- Entry Dir Time Size Name
- 1 1 1173897037 152 test.c
-
- Because the main symtab was created with only DW_AT_name, it was named
- "test.c". And because the path built from the line header contained the
- "directory" part, it was "/home/maxim/W/BadgerPass/PR_14999/test.c".
- Because of this mismatch, thing didn't work, so they added this code to
- prepend the compilation directory to the existing subfile names, so that
- this specific case would work.
-
- With the changes done earlier in this series, where subfiles are
- identified using the "most complete path possible", this case would be
- handled. The main subfile's would be
- "/home/maxim/W/BadgerPass/PR_14999/test.c" from the start
- (DW_AT_comp_dir + DW_AT_name). It's not so different from some DWARF 5
- cases actually, which make the compilation directory explicit in the
- line table header.
-
- I therefore think that this code is no longer needed. It does feel like
- a quick hack to make one specific case work, and we have a more general
- solution now. Also, this code was introduced to work around a problem
- in the DWARF debug info or the DWARF debug info reader. In general, I
- think it's preferable for these hacks to be located in the specific
- debug info reader code, rather than in the common code.
-
- Even though this code was added to work around a DWARF reader problem,
- it's possible that some other debug info reader has started taking
- advantage of this code in the mean time. It's very difficult to
- know or verify, but I think the likelyhood is quite small, so I'm
- proposing to get rid of it to simplify things a little bit.

-
- gdb: add "id" fields to identify symtabs and subfiles
- Printing macros defined in the main source file doesn't work reliably
- using various toolchains, especially when DWARF 5 is used. For example,
- using the binaries produced by either of these commands:
-
- $ gcc --version
- gcc (GCC) 11.2.0
- $ ld --version
- GNU ld (GNU Binutils) 2.38
- $ gcc test.c -g3 -gdwarf-5
-
- $ clang --version
- clang version 13.0.1
- $ clang test.c -gdwarf-5 -fdebug-macro
-
- I get:
-
- $ ./gdb -nx -q --data-directory=data-directory a.out
- (gdb) start
- Temporary breakpoint 1 at 0x111d: file test.c, line 6.
- Starting program: /home/simark/build/binutils-gdb-one-target/gdb/a.out
-
- Temporary breakpoint 1, main () at test.c:6
- 6 return ZERO;
- (gdb) p ZERO
- No symbol "ZERO" in current context.
-
- When starting to investigate this (taking the gcc-compiled binary as an
- example), we see that GDB fails to look up the appropriate macro scope
- when evaluating the expression. While stopped in
- macro_lookup_inclusion:
-
- (top-gdb) p name
- $1 = 0x62100011a980 "test.c"
- (top-gdb) p source.filename
- $2 = 0x62100011a9a0 "/home/simark/build/binutils-gdb-one-target/gdb/test.c"
-
- `source` is the macro_source_file that we would expect GDB to find.
- `name` comes from the symtab::filename field of the symtab we are
- stopped in. GDB doesn't find the appropriate macro_source_file because
- the name of the macro_source_file doesn't match exactly the name of the
- symtab.
-
- The name of the main symtab comes from the compilation unit's
- DW_AT_name, passed to the buildsym_compunit's constructor:
-
- https://gitlab.com/gnutools/binutils-gdb/-/blob/4815d6125ec580cc02a1094d61b8c9d1cc83c0a1/gdb/dwarf2/read.c#L10627-10630
-
- The contents of DW_AT_name, in this case, is "test.c". It is typically
- (what I witnessed all compilers do) the same string that was passed to
- the compiler on the command-line.
-
- The name of the macro_source_file comes from the line number program
- header's file table, from the call to the line_header::file_file_name
- method:
-
- https://gitlab.com/gnutools/binutils-gdb/-/blob/4815d6125ec580cc02a1094d61b8c9d1cc83c0a1/gdb/dwarf2/macro.c#L54-65
-
- line_header::file_file_name prepends the directory path that the file
- entry refers to, in the file table (if the file name is not already
- absolute). In this case, the file name is "test.c", appended to the
- directory "/home/simark/build/binutils-gdb-one-target/gdb".
-
- Because the symtab's name is not created the same way as the
- macro_source_file's name is created, we get this mismatch. GDB fails to
- find the appropriate macro scope for the symtab, and we can't print
- macros when stopped in that symtab.
-
- To make this work, we must ensure that paths produced in these two ways
- end up identical. This can be tricky because of the different ways a
- path can be passed to the compiler by the user.
-
- Another thing to consider is that while the main symtab's name (or
- subfile, before it becomes a symtab) is created using DW_AT_name, the
- main symtab is also referred to using its entry in the line table
- header's file table, when processing the line table. We must therefore
- ensure that the same name is produced in both cases, so that a call to
- "start_subfile" for the main subfile will correctly find the
- already-created subfile, created by buildsym_compunit's constructor. If
- we fail to do that, things still often work, because of a fallback: the
- watch_main_source_file_lossage method. This method determines that if
- the main subfile has no symbols but there exists another subfile with
- the same basename (e.g. "test.c") that does have symbols, it's probably
- because there was some filename mismatch. So it replaces the main
- subfile with that other subfile. I think that heuristic is useful as a
- last effort to work around any bug or bad debug info, but I don't think
- we should design things such as to rely on it. It's a heuristic, it can
- get things wrong. So in my search for a fix, it is important that given
- some good debug info, we don't end up relying on that for things to
- work.
-
- A first attempt at fixing this was to try to prepend the compilation
- directory here or not prepend it there. In practice, because of all the
- possible combinations of debug info the compilers produce, it was not
- possible to get something that would produce reliable, consistent paths.
-
- Another attempt at fixing this was to make both macro_source_file
- objects and symtab objects use the most complete form of path possible.
- That means to prepend directories at least until we get an absolute
- path. In theory, we should end up with the same path in all cases.
- This generally worked, but because it changed the symtab names, it
- resulted in user-visible changes (for example, paths to source files in
- Breakpoint hit messages becoming always absolute). I didn't find this
- very good, first because there is a "set filename-display" setting that
- lets the user control how they want the paths to be displayed, and that
- would suddenly make this setting completely ineffective (although even
- today, it is a bit dependent on the debug info). Second, it would
- require a good amount of testsuite tweaks to make tests accept these
- suddenly absolute paths.
-
- This new patch is a slight variation of that: it adds a new field called
- "filename_for_id" in struct symtab and struct subfile, next to the
- existing filename field. The goal is to separate the internal ids used
- for finding objects from the names used for presentation. This field is
- used for identifying subfiles, symtabs and macro_source_files
- internally. For DWARF symtabs, this new field is meant to contain the
- "most complete possible" path, as discussed above. So for a given file,
- it must always be in the same form, everywhere. The existing
- symtab::filename field remains the one used for printing to the user, so
- there shouldn't be any change in how paths are printed.
-
- Changes in the core symtab files are:
-
- - Add "name_for_id" and "filename_for_id" fields to "struct subfile"
- and "struct symtab", next to existing "name" and "filename" fields.
- - Make buildsym_compunit::buildsym_compunit and
- buildsym_compunit::start_subfile accept a "name_for_id" parameter
- next to the existing "name" ones.
- - Make buildsym_compunit::start_subfile use "name_for_id" for looking
- up existing subfiles. This is the key thing for making calls
- to start_subfile for the main source file look up the existing
- subfile successfully, and avoid relying on
- watch_main_source_file_lossage.
- - Make sal_macro_scope pass "filename_for_id", rather than "filename",
- to macro_lookup_inclusion. This is the key thing to making the
- lookup work and macro printing work.
-
- Changes in the DWARF files are:
-
- - Make line_header::file_file_name return the "most complete possible"
- name. The only pre-existing user of this method is the macro code,
- to give the macro_source_file objects their name. And we now want
- them to have this "most complete possible" name, which will match the
- corresponding symtab's "filename_for_id".
- - Make dwarf2_cu::start_compunit_symtab pass the "most complete
- possible" name for the main symtab's "filename_for_id". In this
- context, where the info comes from the compilation unit's DW_AT_name
- / DW_AT_comp_dir, it means prepending DW_AT_comp_dir to DW_AT_name if
- DW_AT_name is not already absolute.
- - Change dwarf2_start_subfile to build a name_for_id for the subfile
- being started. The simplest way is to re-use
- line_header::file_file_name, since the callers always have a
- file_entry handy. This ensures that it will get the exact same path
- representation as the macro code does, for the same file (since it
- also uses line_header::file_file_name).
- - Update calls to allocate_symtab to pass the "name_for_id" from the
- subfile.
-
- Tests exercising all this are added by the following patch.
-
- Of all the cases I tried, the only one I found that ends up relying on
- watch_main_source_file_lossage is the following one:
-
- $ clang --version
- clang version 13.0.1
- Target: x86_64-pc-linux-gnu
- Thread model: posix
- InstalledDir: /usr/bin
- $ clang ./test.c -g3 -O0 -gdwarf-4
- $ ./gdb -nx --data-directory=data-directory -q -readnow -iex "set debug symtab-create 1" a.out
- ...
- [symtab-create] start_subfile: name = test.c, name_for_id = /home/simark/build/binutils-gdb-one-target/gdb/test.c
- [symtab-create] start_subfile: name = ./test.c, name_for_id = /home/simark/build/binutils-gdb-one-target/gdb/./test.c
- [symtab-create] start_subfile: name = ./test.c, name_for_id = /home/simark/build/binutils-gdb-one-target/gdb/./test.c
- [symtab-create] start_subfile: found existing symtab with name_for_id /home/simark/build/binutils-gdb-one-target/gdb/./test.c (/home/simark/build/binutils-gdb-one-target/gdb/./test.c)
- [symtab-create] watch_main_source_file_lossage: using subfile ./test.c as the main subfile
-
- As we can see, there are two forms used for "test.c", one with a "." and
- one without. This comes from the fact that the compilation unit DIE
- contains:
-
- DW_AT_name ("test.c")
- DW_AT_comp_dir ("/home/simark/build/binutils-gdb-one-target/gdb")
-
- without a ".", and the line table for that file contains:
-
- include_directories[ 1] = "."
- file_names[ 1]:
- name: "test.c"
- dir_index: 1
-
- When assembling the filename from that entry, we get a ".".
-
- It is a bit unexpected that the main filename resulting from the line
- table header does not match exactly the name in the compilation unit.
- For instance, gcc uses "./test.c" for the DW_AT_name, which gives
- identical paths in the compilation unit and in the line table header.
-
- Similarly, with DWARF 5:
-
- $ clang ./test.c -g3 -O0 -gdwarf-5
-
- clang create two entries that refer to the same file but are of in a different
- form.
-
- include_directories[ 0] = "/home/simark/build/binutils-gdb-one-target/gdb"
- include_directories[ 1] = "."
- file_names[ 0]:
- name: "test.c"
- dir_index: 0
- file_names[ 1]:
- name: "test.c"
- dir_index: 1
-
- The first file name produces a path without a "." while the second does.
- This is not caught by watch_main_source_file_lossage, because of
- dwarf_decode_lines that creates a symtab for each file entry in the line
- table. It therefore appears as "non-empty" to
- watch_main_source_file_lossage. This results in two symtabs:
-
- (gdb) maintenance info symtabs
- { objfile /home/simark/build/binutils-gdb-one-target/gdb/a.out ((struct objfile *) 0x613000005d00)
- { ((struct compunit_symtab *) 0x62100011aca0)
- debugformat DWARF 5
- producer clang version 13.0.1
- name test.c
- dirname /home/simark/build/binutils-gdb-one-target/gdb
- blockvector ((struct blockvector *) 0x621000129ec0)
- user ((struct compunit_symtab *) (null))
- { symtab test.c ((struct symtab *) 0x62100011ad20)
- fullname (null)
- linetable ((struct linetable *) 0x0)
- }
- { symtab ./test.c ((struct symtab *) 0x62100011ad60)
- fullname (null)
- linetable ((struct linetable *) 0x621000129ef0)
- }
- }
- }
-
- I am not sure what is the consequence of this, but this is also what
- happens before my patch, so I think its acceptable to leave it as-is.
-
- To handle these two cases nicely, I think we will need a function that
- removes the unnecessary "." from path names, something that can be done
- later.
-
- Finally, I made a change in find_file_and_directory is necessary to
- avoid breaking test
-
- gdb.dwarf2/dw2-compdir-oldgcc.exp: info source gcc42
-
- Without that change, we would get:
-
- (gdb) info source
- Current source file is /dir/d/dw2-compdir-oldgcc42.S
- Compilation directory is /dir/d
-
- whereas the expected result is:
-
- (gdb) info source
- Current source file is dw2-compdir-oldgcc42.S
- Compilation directory is /dir/d
-
- This test was added here:
-
- https://sourceware.org/pipermail/gdb-patches/2012-November/098144.html
-
- Long story short, GCC <= 4.2 apparently had a bug where it would
- generate a DW_AT_name with a full path ("/dir/d/dw2-compdir-oldgcc42.S")
- and no DW_AT_comp_dir. The line table has one entry with filename
- "dw2-compdir-oldgcc42.S", which refers to directory 0. Directory 0
- normally refers to the compilation unit's comp dir, but it is
- non-existent in this case.
-
- This caused some symtab lookup problems, and to work around them, some
- workaround was added, which today reads as:
-
- if (res.get_comp_dir () == nullptr
- && producer_is_gcc_lt_4_3 (cu)
- && res.get_name () != nullptr
- && IS_ABSOLUTE_PATH (res.get_name ()))
- res.set_comp_dir (ldirname (res.get_name ()));
-
- Source: https://gitlab.com/gnutools/binutils-gdb/-/blob/6577f365ebdee7dda71cb996efa29d3714cbccd0/gdb/dwarf2/read.c#L9428-9432
-
- It extracts an artificial DW_AT_comp_dir from DW_AT_name, if there is no
- DW_AT_comp_dir and DW_AT_name is absolute.
-
- Prior to my patch, a subfile would get created with filename
- "/dir/d/dw2-compdir-oldgcc42.S", from DW_AT_name, and another would get
- created with filename "dw2-compdir-oldgcc42.S" from the line table's
- file table. Then watch_main_source_file_lossage would kick in and merge
- them, keeping only the "dw2-compdir-oldgcc42.S" one:
-
- [symtab-create] start_subfile: name = /dir/d/dw2-compdir-oldgcc42.S
- [symtab-create] start_subfile: name = dw2-compdir-oldgcc42.S
- [symtab-create] start_subfile: name = dw2-compdir-oldgcc42.S
- [symtab-create] start_subfile: found existing symtab with name dw2-compdir-oldgcc42.S (dw2-compdir-oldgcc42.S)
- [symtab-create] watch_main_source_file_lossage: using subfile dw2-compdir-oldgcc42.S as the main subfile
-
- And so "info source" would show "dw2-compdir-oldgcc42.S" as the
- filename.
-
- With my patch applied, but without the change in
- find_file_and_directory, both DW_AT_name and the line table would try to
- start a subfile with the same filename_for_id, and there was no need for
- watch_main_source_file_lossage - which is what we want:
-
- [symtab-create] start_subfile: name = /dir/d/dw2-compdir-oldgcc42.S, name_for_id = /dir/d/dw2-compdir-oldgcc42.S
- [symtab-create] start_subfile: name = dw2-compdir-oldgcc42.S, name_for_id = /dir/d/dw2-compdir-oldgcc42.S
- [symtab-create] start_subfile: found existing symtab with name_for_id /dir/d/dw2-compdir-oldgcc42.S (/dir/d/dw2-compdir-oldgcc42.S)
- [symtab-create] start_subfile: name = dw2-compdir-oldgcc42.S, name_for_id = /dir/d/dw2-compdir-oldgcc42.S
- [symtab-create] start_subfile: found existing symtab with name_for_id /dir/d/dw2-compdir-oldgcc42.S (/dir/d/dw2-compdir-oldgcc42.S)
-
- But since the one with name == "/dir/d/dw2-compdir-oldgcc42.S", coming
- from DW_AT_name, gets created first, it wins, and the symtab ends up
- with "/dir/d/dw2-compdir-oldgcc42.S" as the name, "info source" shows
- "/dir/d/dw2-compdir-oldgcc42.S" and the test breaks.
-
- This is not wrong per-se, after all DW_AT_name is
- "/dir/d/dw2-compdir-oldgcc42.S", so it wouldn't be wrong to report the
- current source file as "/dir/d/dw2-compdir-oldgcc42.S". If you compile
- a file passing "/an/absolute/path.c", DW_AT_name typically contains (at
- least with GCC) "/an/absolute/path.c" and GDB tells you that the source
- file is "/an/absolute/path.c". But we can also keep the existing
- behavior fairly easily with a little change in find_file_and_directory.
- When extracting an artificial DW_AT_comp_dir from DW_AT_name, we now
- modify the name to just keep the file part. The result is coherent with
- what compilers do when you compile a file by just passing its filename
- ("gcc path.c -g"):
-
- DW_AT_name ("path.c")
- DW_AT_comp_dir ("/home/simark/build/binutils-gdb-one-target/gdb")
-
- With this change, filename_for_id is still the full name,
- "/dir/d/dw2-compdir-oldgcc42.S", but the filename of the subfile /
- symtab (what ends up shown by "info source") is just
- "dw2-compdir-oldgcc42.S", and that makes the test happy.

- gdb/dwarf: pass a file_entry to line_header::file_file_name
- In the following patch, there will be some callers of file_file_name
- that will already have access to the file_entry object for which they
- want the file name. It would be inefficient to have them pass an index,
- only for line_header::file_file_name to re-lookup the same file_entry
- object. Change line_header::file_file_name to accept a file_entry
- object reference, instead of an index to look up.
-
- I think this change makes sense in any case. Callers that have an index
- can first obtain a file_entry using line_header::file_name_at or
- line_header::file_names.
-
- When passing a file_entry object, we can assume that the file_entry's
- index is valid, unlike when passing an index. So, push the special case
- about an invalid index to the sole current caller of file_file_name,
- macro_start_file. I think that error belongs there anyway, since it
- specifically talks about "bad file number in macro information".
-
- This requires recording the file index in the file_entry structure, so
- add that.

- The following patch changes line_header::file_file_name to prepend the

- header needs to know about the compilation directory. Prepare for that
- by adding a constructor that takes it as a parameter, and passing the
- value down everywhere needed. Add a second constructor for the special
- case of building a line_header for doing a hash table lookup, since that
- case doesn't require a compilation directory value.

- libopcodes/aarch64: add support for disassembler styling
- This commit enables disassembler styling for AArch64. After this
- commit it is possible to have objdump style AArch64 disassembler
- output (using --disassembler-color option). Once the required GDB
- patches are merged, GDB will also style the disassembler output.
-
- The changes to support styling are mostly split between two files
- opcodes/aarch64-dis.c and opcodes/aarch64-opc.c.
-
- The entry point for the AArch64 disassembler can be found in
- aarch64-dis.c, this file handles printing the instruction mnemonics,
- and assembler directives (e.g. '.byte', '.word', etc). Some operands,
- mostly relating to assembler directives are also printed from this
- file. This commit changes all of this to pass through suitable
- styling information.
-
- However, for most "normal" instructions, the instruction operands are
- printed using a two step process. From aarch64-dis.c, in the
- print_operands function, the function aarch64_print_operand is called,
- this function is in aarch64-opc.c, and converts an instruction operand
- into a string. Then, back in print_operands (aarch64-dis.c), the
- operand string is printed.
-
- Unfortunately, the string returned by aarch64_print_operand can be
- quite complex, it will include syntax elements, like '[' and ']', in
- addition to register names and immediate values. In some cases, a
- single operand will expand into what will appear (to the user) as
- multiple operands separated with a ','.
-
- This makes the task of styling more complex, all these different
- components need to by styled differently, so we need to get the
- styling information out of aarch64_print_operand in some way.
-
- The solution that I propose here is similar to the solution that I
- used for the i386 disassembler.
-
- Currently, aarch64_print_operand uses snprintf to write the operand
- text into a buffer provided by the caller.
-
- What I propose is that we pass an extra argument to the
- aarch64_print_operand function, this argument will be a structure, the
- structure contains a callback function and some state.
-
- When aarch64_print_operand needs to format part of its output this can
- be done by using the callback function within the new structure, this
- callback returns a string with special embedded markers that indicate
- which mode should be used for each piece of text. Back in
- aarch64-dis.c we can spot these special style markers and use this to
- split the disassembler output up and apply the correct style to each
- piece.
-
- To make aarch64-opc.c clearer a series of new static functions have
- been added, e.g. 'style_reg', 'style_imm', etc. Each of these
- functions formats a piece of text in a different style, 'register' and
- 'immediate' in this case.
-
- Here's an example taken from aarch64-opc.c of the new functions in
- use:
-
- snprintf (buf, size, "[%s, %s]!",
- style_reg (styler, base),

- Arm64: re-work PR gas/27217 fix
- The original approach has resulted in anomalies when . is involved in an
- operand of one of the affected insns. We cannot leave . unresolved, or
- else it'll be resolved at the end of assembly, then pointing to the
- address of a section rather than at the insn of interest. Undo part of
- the original change and instead check whether a relocation cannot be
- omitted in md_apply_fix().
-
- By resolving the expressions again, equates (see the adjustment of the
- respective testcase) will now be evaluated, and hence relocations
- against absolute addresses be emitted. This ought to be okay as long as
- the equates aren't global (and hence can't be overridden). If a need
- for such arises, quite likely the only way to address this would be to
- invent yet another expression evaluation mode, leaving everything
- _except_ . un-evaluated.
-
- There's a further anomaly in how transitive equates are handled. In
-
- .set x, 0x12345678
- .eqv bar, x
- foo:
- adrp x0, x
- add x0, x0, :lo12:x
-
- adrp x0, bar
- add x0, x0, :lo12:bar
-
- the first two relocations are now against *ABS*:0x12345678 (as said
- above), whereas the latter two relocations would be against x. (Before
- the change here, the first two relocations are against x and the latter
- two against bar.) But this is an issue seen elsewhere as well, and would
- likely require adjustments in the target-independent parts of the
- assembler instead of trying to hack around this for every target.

- Remove some unneeded checks in Guile code
- The Guile code generally checks to see if an htab is non-null before

- can change these checks to asserts and simplify the code a little.
-
- Change registry to use less memory
- The registry code creates "registry_data" objects that hold the free
- function and the index; then the registry keys refer to this object.
- However, only the index is really useful, and now that registries have
- a private implementation, just the index can be stored and we can
- reduce the memory use of registries a little bit. This also
- simplifies the code somewhat.

-
- Rewrite registry.h
- This rewrites registry.h, removing all the macros and replacing it
- with relatively ordinary template classes. The result is less code
- than the previous setup. It replaces large macros with a relatively
- straightforward C++ class, and now manages its own cleanup.
-
- The existing type-safe "key" class is replaced with the equivalent
- template class. This approach ended up requiring relatively few
- changes to the users of the registry code in gdb -- code using the key
- system just required a small change to the key's declaration.
-
- All existing users of the old C-like API are now converted to use the
- type-safe API. This mostly involved changing explicit deletion
- functions to be an operator() in a deleter class.
-
- The old "save/free" two-phase process is removed, and replaced with a
- single "free" phase. No existing code used both phases.
-
- The old "free" callbacks took a parameter for the enclosing container
- object. However, this wasn't truly needed and is removed here as
- well.

- gdb/python: Add BreakpointLocation type
- PR python/18385
-
- v7:
- This version addresses the issues pointed out by Tom.
-
- Added nullchecks for Python object creations.
-
- Changed from using PyLong_FromLong to the gdb_py-versions.
-
- Re-factored some code to make it look more cohesive.
-
- Also added the more safe Python reference count decrement PY_XDECREF,
- even though the BreakpointLocation type is never instantiated by the
- user (explicitly documented in the docs) decrementing < 0 is made
- impossible with the safe call.
-
- Tom pointed out that using the policy class explicitly to decrement a
- reference counted object was not the way to go, so this has instead been
- wrapped in a ref_ptr that handles that for us in blocpy_dealloc.
-
- Moved macro from py-internal to py-breakpoint.c.
-
- Renamed section at the bottom of commit message "Patch Description".
-
- v6:
- This version addresses the points Pedro gave in review to this patch.
-
- Added the attributes `function`, `fullname` and `thread_groups`
- as per request by Pedro with the argument that it more resembles the
- output of the MI-command "-break-list". Added documentation for these attributes.
-
- Cleaned up left overs from copy+paste in test suite, removed hard coding
- of line numbers where possible.
-
- Refactored some code to use more c++-y style range for loops
- wrt to breakpoint locations.
-
- Changed terminology, naming was very inconsistent. Used a variety of "parent",
- "owner". Now "owner" is the only term used, and the field in the
- gdb_breakpoint_location_object now also called "owner".
-
- v5:
-
- Changes in response to review by Tom Tromey:
- - Replaced manual INCREF/DECREF calls with
- gdbpy_ref ptrs in places where possible.
- - Fixed non-gdb style conforming formatting
- - Get parent of bploc increases ref count of parent.
- - moved bploc Python definition to py-breakpoint.c
-
- The INCREF of self in bppy_get_locations is due
- to the individual locations holding a reference to
- it's owner. This is decremented at de-alloc time.
-
- The reason why this needs to be here is, if the user writes
- for instance;
-
- py loc = gdb.breakpoints()[X].locations[Y]
-
- The breakpoint owner object is immediately going
- out of scope (GC'd/dealloced), and the location
- object requires it to be alive for as long as it is alive.
-
- Thanks for your review, Tom!
-
- v4:
- Fixed remaining doc issues as per request
- by Eli.
-
- v3:
- Rewritten commit message, shortened + reworded,
- added tests.
-
- Patch Description
-
- Currently, the Python API lacks the ability to
- query breakpoints for their installed locations,
- and subsequently, can't query any information about them, or
- enable/disable individual locations.
-
- This patch solves this by adding Python type gdb.BreakpointLocation.
- The type is never instantiated by the user of the Python API directly,
- but is produced by the gdb.Breakpoint.locations attribute returning
- a list of gdb.BreakpointLocation.
-
- gdb.Breakpoint.locations:
- The attribute for retrieving the currently installed breakpoint
- locations for gdb.Breakpoint. Matches behavior of
- the "info breakpoints" command in that it only
- returns the last known or currently inserted breakpoint locations.
-
- BreakpointLocation contains 7 attributes
-
- 6 read-only attributes:
- owner: location owner's Python companion object
- source: file path and line number tuple: (string, long) / None
- address: installed address of the location
- function: function name where location was set
- fullname: fullname where location was set
- thread_groups: thread groups (inferiors) where location was set.
-
- 1 writeable attribute:
- enabled: get/set enable/disable this location (bool)
-
- Access/calls to these, can all throw Python exceptions (documented in
- the online documentation), and that's due to the nature
- of how breakpoint locations can be invalidated
- "behind the scenes", either by them being removed
- from the original breakpoint or changed,
- like for instance when a new symbol file is loaded, at
- which point all breakpoint locations are re-created by GDB.
- Therefore this patch has chosen to be non-intrusive:
- it's up to the Python user to re-request the locations if
- they become invalid.
-
- Also there's event handlers that handle new object files etc, if a Python
- user is storing breakpoint locations in some larger state they've
- built up, refreshing the locations is easy and it only comes
- with runtime overhead when the Python user wants to use them.
-
- gdb.BreakpointLocation Python type
- struct "gdbpy_breakpoint_location_object" is found in python-internal.h
-
- Its definition, layout, methods and functions
- are found in the same file as gdb.Breakpoint (py-breakpoint.c)
-
- 1 change was also made to breakpoint.h/c to make it possible
- to enable and disable a bp_location* specifically,
- without having its LOC_NUM, as this number
- also can change arbitrarily behind the scenes.
-
- Updated docs & news file as per request.
-
- Testsuite: tests the .source attribute and the disabling of
- individual locations.

- gdb/linux_nat: Write memory using ptrace if /proc/pid/mem is not writable
- Commit 05c06f318fd9a112529dfc313e6512b399a645e4 enabled GDB to access
- memory while threads are running. It did this by accessing
- /proc/PID/task/LWP/mem.
-
- Unfortunately, this interface is not implemented for writing in older
- kernels (such as RHEL6). This means that GDB is unable to insert
- breakpoints on these hosts:
-
- $ ./gdb -q gdb -ex start
- Reading symbols from gdb...
- Temporary breakpoint 1 at 0x40fdd5: file ../../src/gdb/gdb.c, line 28.
- Starting program: /home/rhel6/fsf/linux/gdb/gdb
- Warning:
- Cannot insert breakpoint 1.
- Cannot access memory at address 0x40fdd5
-
- (gdb)
-
- Before this patch, linux_proc_xfer_memory_partial (previously called
- linux_proc_xfer_partial) would return TARGET_XFER_EOF if the write to
- /proc/PID/mem failed. [More specifically, linux_proc_xfer_partial
- would not "bother for one word," but the effect is the essentially
- same.]
-
- This status was checked by linux_nat_target::xfer_partial, which would
- then fallback to using ptrace to perform the operation.
-
- This is the specific hunk that removed the fallback:
-
- - xfer = linux_proc_xfer_partial (object, annex, readbuf, writebuf,
- - offset, len, xfered_len);
- - if (xfer != TARGET_XFER_EOF)
- - return xfer;
- + return linux_proc_xfer_memory_partial (readbuf, writebuf,
- + offset, len, xfered_len);
- + }
-
- return inf_ptrace_target::xfer_partial (object, annex, readbuf, writebuf,
- offset, len, xfered_len);
-
- This patch makes linux_nat_target::xfer_partial go straight to writing
- memory via ptrace if writing via /proc/pid/mem is not possible in the
- running kernel, enabling GDB to insert breakpoints on these older
- kernels. Note that a recent patch changed the return status from
- TARGET_XFER_EOF to TARGET_XFER_E_IO.
-
- Tested on {unix,native-gdbserver,native-extended-gdbserver}/-m{32,64}
- on x86_64, s390x, aarch64, and ppc64le.

- gdb: rename gdbarch_tdep struct to fix g++ 4.8 build
- After the commit:
-
- commit 08106042d9f5fdff60c129bf33190639f1a98b2a
- Date: Thu May 19 13:20:17 2022 +0100
-
- gdb: move the type cast into gdbarch_tdep
-
- GDB would no longer build using g++ 4.8. The issue appears to be some
- confusion caused by GDB having 'struct gdbarch_tdep', but also a
- templated function called 'gdbarch_tdep'. Prior to the above commit
- the gdbarch_tdep function was not templated, and this compiled just
- fine. Note that the above commit compiles just fine with later
- versions of g++, so this issue was clearly fixed at some point, though
- I've not tried to track down exactly when.
-
- In this commit I propose to fix the g++ 4.8 build problem by renaming
- 'struct gdbarch_tdep' to 'struct gdbarch_tdep_base'. This rename
- better represents that the struct is only ever used as a base class,
- and removes the overloading of the name, which allows GDB to build
- with g++ 4.8.
-
- I've also updated the comment on 'struct gdbarch_tdep_base' to fix a
- typo, and the comment on the 'gdbarch_tdep' function, to mention that
- in maintainer mode a run-time type check is performed.

- gdb/varobj: Fix varobj_invalidate_iter
- The varobj_invalidate function is meant to be called when restarting a
- process, and check at this point if some of the previously existing
- varobj can be recreated in the context of the new process.
-
- Two kind of varobj are subject to re-creation: global varobj (i.e.
- varobj which reference a global variable), and floating varobj (i.e.
- varobj which are always re-evaluated in the context of whatever is
- the currently selected frame at the time of evaluation).
-
- However, in the re-creation process, the varobj_invalidate_iter
- recreates floating varobj as non-floating, due to an invalid parameter.
- This patches fixes this and adds an assertion to check that if a varobj
- is indeed recreated, it matches the original varobj "floating" property.
-
- Another issue is that if at this recreation time the expression watched
- by the floating varobj is not in scope, then the varobj is marked as
- invalid. If later the user selects a frame where the expression becomes
- valid, the varobj remains invalid and this is wrong. This patch also
- make sure that floating varobj are not invalidated if they cannot be
- evaluated.
-
- The last important thing to note is that due to the previous patch, when
- varobj_invalidate is executed (in the context of a new process), any
- global var have already been invalidated (this has been done when the
- objfile it referred to got invalidated). As a consequence,
- varobj_invalidate tries to recreate vars which are already marked as
- invalid. This does not entirely feels right, but I keep this behavior
- for backward compatibility.

- Tested on x86_64-linux

- gdb/varobj: Fix use after free in varobj
- Varobj object contains references to types, variables (i.e. struct
- variable) and expression. All of those can reference data on an
- objfile's obstack. It is possible for this objfile to be deleted (and
- the obstack to be feed), while the varobj remains valid. Later, if the
- user uses the varobj, this will result in a use-after-free error. With
- address sanitizer build, this leads to a plain error. For non address
- sanitizer build we might see undefined behaviour, which manifest
- themself as assertion failures when accessing data backed by feed
- memory.
-
- This can be observed if we create a varobj that refers to ta symbol in a
- shared library, after either the objfile gets reloaded (using the `file`
- command) or after the shared library is unloaded (with a call to dlclose
- for example).
-
- This patch fixes those issues by:
-
- - Adding cleanup procedure to the free_objfile observable. When
- activated this observer clears expressions referencing the objfile
- being freed, and removes references to blocks belonging to this
- objfile.
- - Adding varobj support in the `preserve_values` (gdb.value.c). This
- ensures that before the objfile is unloaded, any type owned by the
- objfile referenced by the varobj is replaced by an equivalent type
- not owned by the objfile. This process is done here instead of in the
- free_objfile observer in order to reuse the type hash table already
- used for similar purpose when replacing types of values kept in the
- value history.
-
- This patch also makes sure to keep a reference to the expression's
- gdbarch and language_defn members when the varobj->root->exp is
- initialized. Those structures outlive the objfile, so this is safe.
- This is done because those references might be used initialize a python
- context even after exp is invalidated. Another approach could have been
- to initialize the python context with default gdbarch and language_defn
- (i.e. nullptr) if expr is NULL, but since we might still try to display
- the value which was obtained by evaluating exp when it was still valid,
- keeping track of the context which was used at this time seems
- reasonable.
-
- Tested on x86_64-Linux.

- MI: mi_runto -pending
- With the CLI testsuite's runto proc, we can pass "allow-pending" as an
- option, like:
-
- runto func allow-pending
-
- That is currently not possible with MI's mi_runto, however. This
- patch makes it possible, by adding a new "-pending" option to
- mi_runto.
-
- A pending breakpoint shows different MI attributes compared to a
- breakpoint with a location, so the regexp returned by
- mi_make_breakpoint isn't suitable. Thus, add a new
- mi_make_breakpoint_pending proc for pending breakpoints.
-
- Tweak mi_runto to let it take and pass down arguments.

- set/show python dont-write-bytecode fixes
- GDB uses the environment variable PYTHONDONTWRITEBYTECODE to
- determine whether or not to write the result of byte-compiling
- python modules when the "python dont-write-bytecode" setting
- is "auto". Simon noticed that GDB's implementation doesn't
- follow the Python documentation.
-
- At present, GDB only checks for the existence of this environment
- variable. That is not sufficient though. Regarding
- PYTHONDONTWRITEBYTECODE, this document...
-
- https://docs.python.org/3/using/cmdline.html
-
- ...says:
-
- If this is set to a non-empty string, Python won't try to write
- .pyc files on the import of source modules.
-
- This commit fixes GDB's handling of PYTHONDONTWRITEBYTECODE by adding
- an empty string check.
-
- This commit also corrects the set/show command documentation for
- "python dont-write-bytecode". The current doc was just a copy
- of that for set/show python ignore-environment.
-
- During his review of an earlier version of this patch, Eli Zaretskii
- asked that the help text that I proposed for "set/show python
- dont-write-bytecode" be expanded. I've done that in addition to
- clarifying the documentation of this option in the GDB manual.

-
- While running some tests using the Python disassembler API, I

- gdb: fix use of uninitialised gdb_printing_disassembler::m_in_comment
- Simon pointed out that gdb_printing_disassembler::m_in_comment can be
- used uninitialised by the Python disassembler API code. This issue
- was spotted when GDB was built with the undefined behaviour sanitizer,
- and causes the gdb.python/py-disasm.exp test to fail like this:
-
- (gdb) PASS: gdb.python/py-disasm.exp: global_disassembler=GlobalPreInfoDisassembler: python add_global_disassembler(GlobalPreInfoDisassembler)

- /home/user/src/binutils-gdb/gdb/disasm.h:144:12: runtime error: load of value 118, which is not a valid value for type 'bool'
-
- The problem is that in disasmpy_builtin_disassemble we create a new
- instance of gdbpy_disassembler, which is a sub-class of
- gdb_printing_disassembler, however, the m_in_comment field is never
- initialised.
-
- This commit fixes the issue by providing a default initialisation
- value for m_in_comment in disasm.h. As we only ever disassemble a
- single instruction in disasmpy_builtin_disassemble then we don't need
- to worry about reseting m_in_comment back to false after the single
- instruction has been disassembled.
-
- With this commit the above issue is resolved and
- gdb.python/py-disasm.exp now passes.

- binutils-gdb/git: highlight whitespace errors in source files
- For a long time I've had this in my ~/.gitconfig:
-
- [core]
- whitespace = space-before-tab,indent-with-non-tab,trailing-space
-
- which causes git to show me if I muck up and use spaces instead of
- tabs, or leave in trailing whitespace. I find this really useful.
-
- I recently proposed adding something like this to the .gitattributes
- files for the GDB sub-directories (gdb, gdbsupport, and gdbserver)[1],
- however, the question was asked - couldn't this be done at the top
- level?
-
- So, in this commit, I propose to update the top-level .gitattributes
- file, after this commit, any git diff on a C, C++, Expect, or TCL
- source file, will highlight the following whitespace errors:
-
- (a) Use a space before a tab at the start of a line,
-
- (b) Use of spaces where a tab could be used at the start of a line,
- and
-
- (c) Any trailing whitespace.
-
- Errors are only highlighted in the diff on new or modified lines, so
- you don't get spammed for errors on context lines that you haven't
- modified.
-
- The only downside I see to adding this at the top level is if there
- are any sub-directories that don't follow the tabs/spaces indentation
- rules very well already, in those directories you'll end up hitting
- issues any time you edit a line. For GDB we're usually pretty good,
- so having this highlighting isn't an issue.

- libopcodes/ppc: add support for disassembler styling
- This commit adds disassembler styling to the libopcodes ppc
- disassembler. This conversion was pretty straight forward, I just
- converted the fprintf_func calls to fprintf_styled_func calls and
- added an appropriate style.
-
- For testing the new styling I just assembled then disassembled the
- source files in gas/testsuite/gas/ppc and manually checked that the
- styling looked reasonable.
-
- I think the only slightly weird case was how things like '4*cr1+eq'
- are styled. As best I can tell, this construct, used for example in
- this instruction:
-
- crand 4*cr1+lt,4*cr1+gt,4*cr1+eq
-
- is used to access a field of a control register. I initially tried
- styling this whole construct as a register[1], but during review it
- was suggested that instead different parts of the text should have
- different styles. In this commit I propose styling '4*cr1+lt' like
- this:
-
- 4 - immediate,
- * - text,
- cr1 - register
- + - text
- lt - sub-mnemonic
-
- If the user does not request styled output from objdump, then there
- should be no change in the disassembler output after this commit.

- wondering what could have gone wrong, and while I doubt this patch
- would have fixed the PR, there are some improvements that can be made
- to cater for user silliness.
-
- I also noticed that when -z relro -z now sections are created out of
- order, with .got before .plt in the section headers but .got is laid
- out at a higher address. That's due to the address expression for
- .branch_lt referencing SIZEOF(.got) and so calling init_os (which
- creates a bfd section) for .got before the .plt section is created.
- Fix that by ignoring SIZEOF in exp_init_os. Unlike ADDR and LOADADDR
- which need to reference section vma and lma respectively, SIZEOF can
- and does cope with a missing bfd section by returning zero for its
- size, which of course is correct.
-

- * ldlang.c (exp_init_os): Don't create a bfd section for SIZEOF.
- * emulparams/elf64ppc.sh (OTHER_RELRO_SECTIONS_2): Revise

- [gdb/symtab] Fix duplicate CUs in all_comp_units
- When running test-case gdb.cp/cpexprs-debug-types.exp with target board
- cc-with-debug-names on a system with gcc 12.1.1 (defaulting to dwarf 5), I
- run into:
- ...
- (gdb) file cpexprs-debug-types^M
- Reading symbols from cpexprs-debug-types...^M
- warning: Section .debug_aranges in cpexprs-debug-types has duplicate \
- debug_info_offset 0x0, ignoring .debug_aranges.^M
- gdb/dwarf2/read.h:309: internal-error: set_length: \
- Assertion `m_length == length' failed.^M
- ...
-
- The exec contains a .debug_names section, which gdb rejects due to
- .debug_names containing a list of TUs, while the exec doesn't contain a
- .debug_types section (which is what you'd expect for dwarf 4).
-
- Gdb then falls back onto the cooked index, which calls create_all_comp_units
- to create all_comp_units. However, the failed index reading left some
- elements in all_comp_units, so we end up with duplicates in all_comp_units,
- which causes the misleading complaint and the assert.
-
- Fix this by:
- - asserting at the start of create_all_comp_units that all_comp_units is empty,
- as we do in create_cus_from_index and create_cus_from_debug_names, and
- - cleaning up all_comp_units when failing in dwarf2_read_debug_names.
-
- Add a similar cleanup in dwarf2_read_gdb_index.

- gdb: ensure the cast in gdbarch_tdep is valid
- This commit makes use of gdb::checked_static_cast when casting the
- generic gdbarch_tdep pointer to a specific sub-class type. This means
- that, when compiled in developer mode, GDB will validate that the cast
- is correct.
-
- In order to use gdb::checked_static_cast the types involved must have
- RTTI, which is why the gdbarch_tdep base class now has a virtual
- destructor.
-
- Assuming there are no bugs in GDB where we cast a gdbarch_tdep pointer
- to the wrong type, then there should be no changes after this commit.
-
- If any bugs do exist, then GDB will now assert (in a developer build).
-

-
- gdbsupport: add checked_static_cast
- This commit was inspired by these mailing list posts:
-
- https://sourceware.org/pipermail/gdb-patches/2022-June/190323.html
- https://sourceware.org/pipermail/gdb-patches/2022-April/188098.html
-
- The idea is to add a new function gdb::checked_static_cast, which can,
- in some cases, be used as a drop-in replacement for static_cast. And
- so, if I previously wrote this:
-
- BaseClass *base = get_base_class_pointer ();
- DerivedClass *derived = static_cast<DerivedClass *> (base);
-
- I can now write:
-
- BaseClass *base = get_base_class_pointer ();
- DerivedClass *derived = gdb::checked_static_cast<DerivedClass *> (base);
-
- The requirement is that BaseClass and DerivedClass must be
- polymorphic.
-
- The benefit of making this change is that, when GDB is built in
- developer mode, a run-time check will be made to ensure that `base`
- really is of type DerivedClass before the cast is performed. If
- `base` is not of type DerivedClass then GDB will assert.
-
- In a non-developer build gdb::checked_static_cast is equivalent to a
- static_cast, and there should be no performance difference.
-
- This commit adds the support function, but does not make use of this
- function, a use will be added in the next commit.

- gdb: move the type cast into gdbarch_tdep
- I built GDB for all targets on a x86-64/GNU-Linux system, and
- then (accidentally) passed GDB a RISC-V binary, and asked GDB to "run"
- the binary on the native target. I got this error:
-
- (gdb) show architecture
- The target architecture is set to "auto" (currently "i386").
- (gdb) file /tmp/hello.rv32.exe
- Reading symbols from /tmp/hello.rv32.exe...
- (gdb) show architecture
- The target architecture is set to "auto" (currently "riscv:rv32").
- (gdb) run
- Starting program: /tmp/hello.rv32.exe
- ../../src/gdb/i387-tdep.c:596: internal-error: i387_supply_fxsave: Assertion `tdep->st0_regnum >= I386_ST0_REGNUM' failed.
-
- What's going on here is this; initially the architecture is i386, this
- is based on the default architecture, which is set based on the native
- target. After loading the RISC-V executable the architecture of the
- current inferior is updated based on the architecture of the
- executable.
-
- When we "run", GDB does a fork & exec, with the inferior being
- controlled through ptrace. GDB sees an initial stop from the inferior
- as soon as the inferior comes to life. In response to this stop GDB
- ends up calling save_stop_reason (linux-nat.c), which ends up trying
- to read register from the inferior, to do this we end up calling
- target_ops::fetch_registers, which, for the x86-64 native target,
- calls amd64_linux_nat_target::fetch_registers.
-
- After this I eventually end up in i387_supply_fxsave, different x86
- based targets will end in different functions to fetch registers, but
- it doesn't really matter which function we end up in, the problem is
- this line, which is repeated in many places:
-
- i386_gdbarch_tdep *tdep = (i386_gdbarch_tdep *) gdbarch_tdep (arch);
-
- The problem here is that the ARCH in this line comes from the current
- inferior, which, as we discussed above, will be a RISC-V gdbarch, the
- tdep field will actually be of type riscv_gdbarch_tdep, not
- i386_gdbarch_tdep. After this cast we are relying on undefined
- behaviour, in my case I happen to trigger an assert, but this might
- not always be the case.
-
- The thing I tried that exposed this problem was of course, trying to
- start an executable of the wrong architecture on a native target. I
- don't think that the correct solution for this problem is to detect,
- at the point of cast, that the gdbarch_tdep object is of the wrong
- type, but, I did wonder, is there a way that we could protect
- ourselves from incorrectly casting the gdbarch_tdep object?
-
- I think that there is something we can do here, and this commit is the
- first step in that direction, though no actual check is added by this
- commit.
-
- This commit can be split into two parts:
-
- (1) In gdbarch.h and arch-utils.c. In these files I have modified
- gdbarch_tdep (the function) so that it now takes a template argument,
- like this:
-
- template<typename TDepType>
- static inline TDepType *
- gdbarch_tdep (struct gdbarch *gdbarch)
- {
- struct gdbarch_tdep *tdep = gdbarch_tdep_1 (gdbarch);
- return static_cast<TDepType *> (tdep);
- }
-
- After this change we are no better protected, but the cast is now
- done within the gdbarch_tdep function rather than at the call sites,
- this leads to the second, much larger change in this commit,
-
- (2) Everywhere gdbarch_tdep is called, we make changes like this:
-
- - i386_gdbarch_tdep *tdep = (i386_gdbarch_tdep *) gdbarch_tdep (arch);
- + i386_gdbarch_tdep *tdep = gdbarch_tdep<i386_gdbarch_tdep> (arch);
-
- There should be no functional change after this commit.
-
- In the next commit I will build on this change to add an assertion in
- gdbarch_tdep that checks we are casting to the correct type.

- gdb: select suitable thread for gdbarch_adjust_breakpoint_address
- The three targets that implement gdbarch_adjust_breakpoint_address are
- arm, frv, and mips. In each of these targets the adjust breakpoint
- address function does some combination of reading the symbol table, or
- reading memory at the location the breakpoint could be placed.
-
- The problem is that performing these actions requires that the current
- inferior and program space be the one in which the breakpoint will be
- placed, and this is not currently always the case.
-
- Consider a GDB session with multiple inferiors. One inferior might be
- a native target while another could be a remote target of a completely
- different architecture. Alternatively, if we consider ARM and
- AArch64, one native inferior might be AArch64, while a second native
- inferior could be ARM.
-
- In these cases it is possible, and valid, for a user to have one
- inferior selected, and place a breakpoint in the other inferior by
- placing a breakpoint on a particular symbol.
-
- If this happens, then currently, when
- gdbarch_adjust_breakpoint_address is called, the wrong inferior (and
- program space) will be selected, and memory reads, and symbol look
- ups, will not return the expected results, this could lead to
- breakpoints being placed in the wrong location.
-
- There are currently two places where gdbarch_adjust_breakpoint_address
- is called:
-
- 1. In infrun.c, in the function handle_step_into_function. In this
- case, I believe that the correct inferior and program space will
- already be selected as this is called as part of the stop event
- handling, so I don't think we need to worry about this case, and
-
- 2. In breakpoint.c, in the function adjust_breakpoint_address, which
- is itself called from code_breakpoint::add_location and
- watch_command_1.
-
- The watch_command_1 case I don't think we need to worry about, this
- is for when a local watch expression is created, which can only be
- in the currently selected inferior, so this case should be fine.
-
- The code_breakpoint::add_location case is the one that needs fixing,
- this is what allows a breakpoint to be created between inferiors.
-
- To fix the code_breakpoint::add_location case, I propose that we pass
- the "correct" program_space (i.e. the program space in which the
- breakpoint will be created) to the adjust_breakpoint_address function.
- Then in adjust_breakpoint_address we can make use of
- switch_to_program_space_and_thread to switch program_space and
- inferior before calling gdbarch_adjust_breakpoint_address.
-
- I discovered this issue while working on a later patch in this
- series. This later patch will detect when we cast the result of
- gdbarch_tdep to the wrong type.
-
- With this later patch in place I ran gdb.multi/multi-arch.exp on an
- AArch64 target. In this situation, two inferiors are created, an
- AArch64 inferior, and an ARM inferior. The test selected the AArch64
- inferior and tries to create a breakpoint in the ARM inferior.
-
- As a result of this we end up in arm_adjust_breakpoint_address, which
- calls arm_pc_is_thumb. Before this commit the AArch64 inferior would
- be current. As a result, all of the checks in arm_pc_is_thumb would
- fail (they rely on reading symbols from the current program space),
- and so, at the end of arm_pc_is_thumb we would call
- arm_frame_is_thumb. However, remember, at this point the current
- inferior is the AArch64 inferior, so the current frame is an AArch64
- frame.
-
- In arm_frame_is_thumb we call arm_psr_thumb_bit, which calls
- gdbarch_tdep and casts the result to arm_gdbarch_tdep. This is wrong,
- the tdep field is of type aarch64_gdbarch_tdep. After this we have
- undefined behaviour.
-
- With this patch in place, we will have switched to a thread in the ARM
- program space before calling arm_adjust_breakpoint_address. As a
- result, we now succeed in looking up the required symbols in
- arm_pc_is_thumb, and so we never call arm_frame_is_thumb.
-
- However, in the worst case scenario, if we did end up calling
- arm_frame_is_thumb, as the current inferior should now be the ARM
- inferior, the current frame should be an ARM frame, so we still should
- not hit undefined behaviour.
-
- I have added an assert to arm_frame_is_thumb.

-
- gdb/mips: rewrite show_mask_address
- This commit is similar to the previous commit, but in this case GDB is
- actually relying on undefined behaviour.
-
- Consider building GDB for all targets on x86-64/GNU-Linux, then doing
- this:
-
- (gdb) show mips mask-address
- Zeroing of upper 32 bits of 64-bit addresses is auto.
- The 32 bit address mask is set automatically. Currently disabled
- (gdb)
-
- The 'show mips mask-address' command ends up in show_mask_address in
- mips-tdep.c, and this function does this:
-
- mips_gdbarch_tdep *tdep
- = (mips_gdbarch_tdep *) gdbarch_tdep (target_gdbarch ());
-
- Later we might pass TDEP to mips_mask_address_p. However, in my
- example above, on an x86-64 native target, the current target
- architecture will be an x86-64 gdbarch, and the tdep field within the
- gdbarch will be of type i386_gdbarch_tdep, not of type
- mips_gdbarch_tdep, as a result the cast above was incorrect, and TDEP
- is not pointing at what it thinks it is.
-
- I also think the current output is a little confusing, we appear to
- have two lines that show the same information, but using different
- words.
-
- The first line comes from calling deprecated_show_value_hack, while
- the second line is printed directly from show_mask_address. However,
- both of these lines are printing the same mask_address_var value. I
- don't think the two lines actually adds any value here.
-
- Finally, none of the text in this function is passed through the
- internationalisation mechanism.
-
- It would be nice to remove another use of deprecated_show_value_hack
- if possible, so this commit does a complete rewrite of
- show_mask_address.
-
- After this commit the output of the above example command, still on my
- x86-64 native target is:
-
- (gdb) show mips mask-address
- Zeroing of upper 32 bits of 64-bit addresses is "auto" (current architecture is not MIPS).
-
- The 'current architecture is not MIPS' text is only displayed when the
- current architecture is not MIPS. If the architecture is mips then we
- get the more commonly seen 'currently "on"' or 'currently "off"', like
- this:
-
- (gdb) set architecture mips
- The target architecture is set to "mips".
- (gdb) show mips mask-address
- Zeroing of upper 32 bits of 64-bit addresses is "auto" (currently "off").
- (gdb)
-
- All the text is passed through the internationalisation mechanism, and
- we only call gdbarch_tdep when we know the gdbarch architecture is
- bfd_arch_mips.

-
- gdb/arm: move fetch of arm_gdbarch_tdep to a more inner scope
- This is a small refactor to resolve an issue before it becomes a
- problem in a later commit.
-
- Move the fetching of an arm_gdbarch_tdep into a more inner scope
- within two functions in arm-tdep.c.
-
- The problem with the current code is that the functions in question
- are used as the callbacks for two set/show parameters. These set/show
- parameters are available no matter the current architecture, but are
- really about controlling an ARM architecture specific setting. And
- so, if I build GDB for all targets on an x86-64/GNU-Linux system, I
- can still do this:
-
- (gdb) show arm fpu
- (gdb) show arm abi
-
- After these calls we end up in show_fp_model and arm_show_abi
- respectively, where we unconditionally do this:
-
- arm_gdbarch_tdep *tdep
- = (arm_gdbarch_tdep *) gdbarch_tdep (target_gdbarch ());
-
- However, the gdbarch_tdep() result will only be a arm_gdbarch_tdep if
- the current architecture is ARM, otherwise the result will actually be
- of some other type.
-
- This isn't actually a problem, as in both cases the use of tdep is
- guarded by a later check that the gdbarch architecture is
- bfd_arch_arm.
-
- This commit just moves the call to gdbarch_tdep() after the
- architecture check.
-
- In a later commit gdbarch_tdep() will be able to spot when we are
- casting the result to the wrong type, and this function will trigger
- assertion failures if things are not fixed.
-
- There should be not user visible changes after this commit.

- [gdb/symtab] Fix bad compile unit index complaint
- I noticed this code in dw2_debug_names_iterator::next:
- ...
- case DW_IDX_compile_unit:
- /* Don't crash on bad data. */
- if (ull >= per_bfd->all_comp_units.size ())
- {
- complaint (_(".debug_names entry has bad CU index %s"
- " [in module %s]"),
- pulongest (ull),
- objfile_name (objfile));
- continue;
- }
- per_cu = per_bfd->get_cu (ull);
- break;
- ...
-
- This code used to DTRT, before we started keeping both CUs and TUs in
- all_comp_units.
-
- Fix by using "per_bfd->all_comp_units.size () - per_bfd->tu_stats.nr_tus"
- instead.
-
- It's hard to produce a test-case for this, but let's try at least to trigger
- the complaint somehow. We start out by creating an exec with .debug_types and
- .debug_names:
- ...
- $ gcc -g ~/hello.c -fdebug-types-section
- $ gdb-add-index -dwarf-5 a.out
- ...
- and verify that we don't see any complaints:
- ...
- $ gdb -q -batch -iex "set complaints 100" ./a.out
- ...
-
- We look at the CU and TU table using readelf -w and conclude that we have
- nr_cus == 6 and nr_tus == 1.
-
- Now override ull in dw2_debug_names_iterator::next for the DW_IDX_compile_unit
- case to 6, and we have:
- ...
- $ gdb -q -batch -iex "set complaints 100" ./a.out
- During symbol reading: .debug_names entry has bad CU index 6 [in module a.out]
- ...
-
- After this, it still crashes because this code in
- dw2_debug_names_iterator::next:
- ...
- /* Skip if already read in. */
- if (m_per_objfile->symtab_set_p (per_cu))
- goto again;
- ...
- is called with per_cu == nullptr.
-
- Fix this by skipping the entry if per_cu == nullptr.
-
- Now revert the fix and observe that the complaint disappears, so we've
- confirmed that the fix is required.
-
- A somewhat similar issue for .gdb_index in dw2_symtab_iter_next has been filed
- as PR29367.
-
- Tested on x86_64-linux, with native and target board cc-with-debug-names.

- Handle Python 3.11 deprecation of PySys_SetPath and Py_SetProgramName
- Python 3.11 deprecates PySys_SetPath and Py_SetProgramName. The
- PyConfig API replaces these and other functions. This commit uses the
- PyConfig API to provide equivalent functionality while also preserving
- support for older versions of Python, i.e. those before Python 3.8.
-
- A beta version of Python 3.11 is available in Fedora Rawhide. Both
- Fedora 35 and Fedora 36 use Python 3.10, while Fedora 34 still used
- Python 3.9. I've tested these changes on Fedora 34, Fedora 36, and
- rawhide, though complete testing was not possible on rawhide due to
- a kernel bug. That being the case, I decided to enable the newer
- PyConfig API by testing PY_VERSION_HEX against 0x030a0000. This
- corresponds to Python 3.10.
-
- We could try to use the PyConfig API for Python versions as early as 3.8,
- but I'm reluctant to do this as there may have been PyConfig related
- bugs in earlier versions which have since been fixed. Recent linux
- distributions should have support for Python 3.10. This should be
- more than adequate for testing the new Python initialization code in
- GDB.
-
- Information about the PyConfig API as well as the motivation behind
- deprecating the old interface can be found at these links:
-
- https://github.com/python/cpython/issues/88279
- https://peps.python.org/pep-0587/
- https://docs.python.org/3.11/c-api/init_config.html
-
- The v2 commit also addresses several problems that Simon found in
- the v1 version.
-
- In v1, I had used Py_DontWriteBytecodeFlag in the new initialization
- code, but Simon pointed out that this global configuration variable
- will be deprecated in Python 3.12. This version of the patch no longer
- uses Py_DontWriteBytecodeFlag in the new initialization code.
- Additionally, both Py_DontWriteBytecodeFlag and Py_IgnoreEnvironmentFlag
- will no longer be used when building GDB against Python 3.10 or higher.
- While it's true that both of these global configuration variables are
- deprecated in Python 3.12, it makes sense to disable their use for
- gdb builds against 3.10 and higher since those are the versions for
- which the PyConfig API is now being used by GDB. (The PyConfig API
- includes different mechanisms for making the same settings afforded
- by use of the soon-to-be deprecated global configuration variables.)
-
- Simon also noted that PyConfig_Clear() would not have be called for
- one of the failure paths. I've fixed that problem and also made the
- rest of the "bail out" code more direct. In particular,
- PyConfig_Clear() will always be called, both for success and failure.
-
- The v3 patch addresses some rebase conflicts related to module
- initialization . Commit 3acd9a692dd ("Make 'import gdb.events' work")
- uses PyImport_ExtendInittab instead of PyImport_AppendInittab. That
- commit also initializes a struct for each module to import. Both the
- initialization and the call to were moved ahead of the ifdefs to avoid
- having to replicate (at least some of) the code three times in various
- portions of the ifdefs.

- Don't stop all threads prematurely after first step of "step N"
- In all-stop mode, when the target is itself in non-stop mode (like
- GNU/Linux), if you use the "step N" (or "stepi/next/nexti N") to step
- a thread a number of times:
-
- (gdb) help step
- step, s
- Step program until it reaches a different source line.
- Usage: step [N]
- Argument N means step N times (or till program stops for another reason).
-
- ... GDB prematurely stops all threads after the first step, and
- doesn't re-resume them for the subsequent N-1 steps. It's as if for
- the 2nd and subsequent steps, the command was running with
- scheduler-locking enabled.
-
- This can be observed with the testcase added by this commit, which
- looks like this:
-
- static pthread_barrier_t barrier;
-
- static void *
- thread_func (void *arg)
- {
- pthread_barrier_wait (&barrier);
- return NULL;
- }
-
- int
- main ()
- {
- pthread_t thread;
- int ret;
-
- pthread_barrier_init (&barrier, NULL, 2);
-
- /* We run to this line below, and then issue "next 3". That should
- step over the 3 lines below and land on the return statement. If
- GDB prematurely stops the thread_func thread after the first of
- the 3 nexts (and never resumes it again), then the join won't
- ever return. */
- pthread_create (&thread, NULL, thread_func, NULL); /* set break here */
- pthread_barrier_wait (&barrier);
- pthread_join (thread, NULL);
-
- return 0;
- }
-
- The test hangs and times out without the GDB fix:
-
- (gdb) next 3
- [New Thread 0x7ffff7d89700 (LWP 525772)]
- FAIL: gdb.threads/step-N-all-progress.exp: non-stop=off: target-non-stop=on: next 3 (timeout)
-
- The problem is a core gdb bug.
-
- When you do "step/stepi/next/nexti N", GDB internally creates a
- thread_fsm object and associates it with the stepping thread. For the
- stepping commands, the FSM's class is step_command_fsm. That object
- is what keeps track of how many steps are left to make. When one step
- finishes, handle_inferior_event calls stop_waiting and returns, and
- then fetch_inferior_event calls the "should_stop" method of the event
- thread's FSM. The implementation of that method decrements the
- steps-left counter. If the counter is 0, it returns true and we
- proceed to presenting the stop to the user. If it isn't 0 yet, then
- the method returns false, indicating to fetch_inferior_event to "keep
- going".
-
- Focusing now on when the first step finishes -- we're in "all-stop"
- mode, with the target in non-stop mode. When a step finishes,
- handle_inferior_event calls stop_waiting, which itself calls
- stop_all_threads to stop everything. I.e., after the first step
- completes, all threads are stopped, before handle_inferior_event
- returns. And after that, now in fetch_inferior_event, we consult the
- thread's thread_fsm::should_stop, which as we've seen, for the first
- step returns false -- i.e., we need to keep_going for another step.
- However, since the target is in non-stop mode, keep_going resumes
- _only_ the current thread. All the other threads remain stopped,
- inadvertently.
-
- If the target is in non-stop mode, we don't actually need to stop all
- threads right after each step finishes, and then re-resume them again.
- We can instead defer stopping all threads until all the steps are
- completed.
-
- So fix this by delaying the stopping of all threads until after we
- called the FSM's "should_stop" method. I.e., move it from
- stop_waiting, to handle_inferior_events's callers,
- fetch_inferior_event and wait_for_inferior.
-
- New test included. Tested on x86-64 GNU/Linux native and gdbserver.

- x86: Make protected symbols local for -shared
- Call _bfd_elf_symbol_refs_local_p with local_protected==true. This has
- 2 noticeable effects for -shared:
-
- * GOT-generating relocations referencing a protected data symbol no
- longer lead to a GLOB_DAT (similar to a hidden symbol).
- * Direct access relocations (e.g. R_X86_64_PC32) no longer has the
- confusing diagnostic below.
-
- __attribute__((visibility("protected"))) void *foo() {
- return (void *)foo;
- }
-
- // gcc -fpic -shared -fuse-ld=bfd
- relocation R_X86_64_PC32 against protected symbol `foo' can not be used when making a shared object
-
- The new behavior matches arm, aarch64 (commit
- 83c325007c5599fa9b60b8d5f7b84842160e1d1b), and powerpc ports, and other
- linkers: gold and ld.lld.
-
- Note: if some code tries to use direct access relocations to take the
- address of foo, the pointer equality will break, but the error should be
- reported on the executable link, not on the innocent shared object link.
- glibc 2.36 will give a warning at relocation resolving time.
-
- With this change, `#define elf_backend_extern_protected_data 1` is no
- longer effective. Just remove it.
-
- Remove the test "Run protected-func-1 without PIE" since -fno-pic
- address taken operation in the executable doesn't work with protected
- symbol in a shared object by default. Similarly, remove
- protected-data-1a and protected-data-1b. protected-data-1b can be made

- [AArch64] MTE corefile support
- Teach GDB how to dump memory tags for AArch64 when using the gcore command
- and how to read memory tag data back from a core file generated by GDB
- (via gcore) or by the Linux kernel.
-
- The format is documented in the Linux Kernel documentation [1].
-
- Each tagged memory range (listed in /proc/<pid>/smaps) gets dumped to its
- own PT_AARCH64_MEMTAG_MTE segment. A section named ".memtag" is created for each
- of those segments when reading the core file back.
-
- To save a little bit of space, given MTE tags only take 4 bits, the memory tags
- are stored packed as 2 tags per byte.
-
- When reading the data back, the tags are unpacked.
-
- I've added a new testcase to exercise the feature.
-
- Build-tested with --enable-targets=all and regression tested on aarch64-linux

- [AArch64] Support AArch64 MTE memory tag dumps in core files
- The Linux kernel can dump memory tag segments to a core file, one segment
- per mapped range. The format and documentation can be found in the Linux
- kernel tree [1].
-
- The following patch adjusts bfd and binutils so they can handle this new
- segment type and display it accordingly. It also adds code required so GDB
- can properly read/dump core file data containing memory tags.
-
- Upon reading, each segment that contains memory tags gets mapped to a
- section named "memtag". These sections will be used by GDB to lookup the tag
- data. There can be multiple such sections with the same name, and they are not
- numbered to simplify GDB's handling and lookup.
-
- There is another patch for GDB that enables both reading
- and dumping of memory tag segments.

- loads a new objfile, and when gdb clears the objfile list. However,
- there's no way to detect the removal of an objfile, say when the
- inferior calls dlclose.
-
- This patch adds a gdb.free_objfile event registry and arranges for an
- event to be emitted in this case.

- Put gdb.base/bt-on-fatal-signal.exp GDB cores in output dir
- I noticed that gdb.base/bt-on-fatal-signal.exp was contributing four
- core files to the count of unexpected core files:
-
- $ make check TESTS="gdb.base/bt-on-fatal-signal.exp"
-
- === gdb Summary ===
-
- # of unexpected core files 4
- # of expected passes 21
-
- These are GDB core dumps. They are expected, however, because the
- whole point of the testcase is to crash GDB with a signal.
-
- Make GDB change its current directory to the output dir just before
- crashing, so that the core files end up there. The result is now:

- Remove array typedef assumption for Ada
- Currently the Ada code assumes that it can distinguish between a
- multi-dimensional array and an array of arrays by looking for an
- intervening typedef -- that is, for an array of arrays, there will be
- a typedef wrapping the innermost array type.
-
- A recent compiler change removes this typedef, which causes a gdb
- failure in the internal AdaCore test suite.
-
- This patch handles this case by checking whether the array type in
- question has a name.

- gdb/python: look for python, then python 3 at configure time
- It is possible that a system might have a python3 executable, but no
- python executable. For example, on my Fedora system the python2
- package provides /usr/bin/python2, the python3 package provides
- /usr/bin/python3, and the python-unversioned-command package provides
- /usr/bin/python, which picks between python2 and python3.
-
- It is quite possible to only have python3 available on a system.
-
- Currently, when GDB configures, it looks for a 'python' executable.
- If non is found then GDB will be built without python support. Or the
- user needs to configure using --with-python=/usr/bin/python3.
-
- This commit updates GDB's configure.ac script to first look for
- 'python', and then 'python3'. Now, on a system that only has a
- python3 executable, GDB will automatically find, and use that in order
- to provide python support, no user supplied configure arguments are
- needed.
-
- I've tested this on my local machine by removing the
- python-unversioned-command package, confirming that there is no longer
- a 'python' executable in my $PATH, and then rebuilding GDB from
- scratch. GDB with this patch has python support.

- x86: correct VMOVSH attributes
- Both forms were missing VexW0 (thus allowing Evex.W=1 to be encoded by
- suitable means, which would cause #UD). The memory operand form further
- was using the wrong Masking value, thus allowing zeroing-masking to be
- encoded for the store form (which would again cause #UD).
-
- x86: re-order insn template fields
- This saves quite a number of shift instructions: The "operands" field
- can now be retrieved by just masking (no shift), and extracting the
- "extension_opcode" field now only requires a (signed) right shift, with
- no prereq left one. (Of course there may be architectures where, in a
- cross build, there might be no difference at all, e.g. when there are
- suitable bitfield extraction insns.)

- [gdbsupport] Improve thread scheduling in parallel_for_each
- When running a task using parallel_for_each, we get the following
- distribution:
- ...
- Parallel for: n_elements: 7271
- Parallel for: minimum elements per thread: 10
- Parallel for: elts_per_thread: 1817
- Parallel for: elements on worker thread 0 : 1817
- Parallel for: elements on worker thread 1 : 1817
- Parallel for: elements on worker thread 2 : 1817
- Parallel for: elements on worker thread 3 : 0
- Parallel for: elements on main thread : 1820
- ...
-
- Note that there are 4 active threads, and scheduling elts_per_thread on each
- of those handles 4 * 1817 == 7268, leaving 3 "left over" elements.
-
- These leftovers are currently handled in the main thread.
-
- That doesn't seem to matter much for this example, but for say 10 threads and
- 99 elements, you'd have 9 threads handling 9 elements and 1 thread handling 18
- elements.
-
- Instead, distribute the left over elements over the worker threads, such that
- we have:
- ...
- Parallel for: elements on worker thread 0 : 1818
- Parallel for: elements on worker thread 1 : 1818
- Parallel for: elements on worker thread 2 : 1818
- Parallel for: elements on worker thread 3 : 0
- Parallel for: elements on main thread : 1817

- PowerPC: Add support for IEEE 128-bit format.
- The test gdb.base/infcall-nested-structs-c.exp fails on a gdb assert
- in function ppc64_sysv_abi_return_value in file gdb/ppc-sysv-tdep.c. The
- assert is due to the missing IEEE 128-bit support in file
- gdb/ppc-sysv-tdep.c.
-
- The IBM long double was the initial float 128-bit support added by IBM
- The IEEE 128-bit support, which is similar IBM long double support, was
- made the default starting with GCC 12. The floating point format
- differences include the number of bits used to encode the exponent
- and significand. Also, IBM long double values are passed in a pair of
- floating point registers. The IEEE 128-bit value is passed in a single
- vector register.
-
- This patch fixes the gdb_assert (ok); in function
- ppc64_sysv_abi_return_value in gdb/ppc-sysv-tdep.c by adding IEEE FLOAT
- 128-bit type support for PowerPC.

- First, while Value.format_string uses the user's settings, it does not

- PowerPC: fix for gdb.base/eh_return.exp
- Disable the Traceback Table generation on PowerPC for this test. The
- Traceback Table consists of a series of bit fields to indicate things like
- the Traceback Table version, language, and specific information about the
- function. The Traceback Table is generated following the end of the code
- for every function by default. The Traceback Table is defined in the
- PowerPC ELF ABI and is intended to support debuggers and exception
- handlers. The Traceback Table is displayed in the disassembly of functions
- by default and is part of the function length. The table is typically
- interpreted by the disassembler as data represented by .long xxx entries.
-
- Generation of the Traceback Table is disabled in this test using the
- PowerPC specific gcc compiler option -mtraceback=no, the xlc option
- additional_flags-qtable=none and the clang optons
- -mllvm -xcoff-traceback-table=false. Disabling the Traceback Table
- generation in this test results in the gdb_test_multiple statement
- correctly locating the address of the bclr instruction before the statement
- "End of assembler dump." in the disassembly output.

- Tighten gdb.threads/no-unwaited-for-left.exp regexps
- A WIP version of a patch
- (https://sourceware.org/pipermail/gdb-patches/2022-June/190202.html)
- resulted in a bug that went unnoticed by the testuite, like so:
-
- (gdb) PASS: gdb.threads/no-unwaited-for-left.exp: enable scheduler-locking, for main thread
- continue
- Continuing.
- [New Thread 1251861.1251861]
- No unwaited-for children left.
- (gdb) PASS: gdb.threads/no-unwaited-for-left.exp: continue stops when the main thread exits
- info threads
- Id Target Id Frame
- 3 Thread 1251861.1251863 "no-unwaited-for" __pthread_clockjoin_ex (threadid=140737351558976, thread_return=0x0, clockid=<optimized out>, abstime=<optimized out>, block=<optimized out>) at pthread_join_common.c:145
- 4 Thread 1251861.1251861 "no-unwaited-for" <unavailable> in ?? ()
-
- The current thread <Thread ID 1> has terminated. See `help thread'.
- (gdb) PASS: gdb.threads/no-unwaited-for-left.exp: only thread 3 left, main thread terminated
-
- Somehow, above, GDB re-added the zombie leader back before printing
- "No unwaited-for children left.". The "only thread 3 left, main
- thread terminated" test should have caught this, but didn't. That is
- because the test's regexp has a ".*" after the part that matches
- thread 3. This commit tightens that regexp to catch such a bug. It
- also tightens the "only main thread left, thread 2 terminated" test's
- regexp in the same way.

- Fix for gdb.base/stap-probe.c
- On PowePC, the test fails on a compile error:
-
- /../binutils-gdb-current/gdb/testsuite/gdb.base/stap-probe.c:107:1: error: expected '=', ',', ';', 'asm' or 'attribute' before 'use_xmm_reg'

-
- static const char * __attribute__((noinline)) ATTRIBUTE_NOCLONE
- use_xmm_reg (int val) <-- line 107
- {

-
- The issue is the ATTRIBUTE_NOCLONE is not defined as an attribute as
- expected. The #define for ATTRIBUTE_NOCLONE can be found in
- ../lib/attributes.h.

-
- As stated in the error message the default "-fcf-protection" and
- "-mindirect-branch' are in compatible. The fcf-protection argument needs
- to be "-fcf-protection=none" for the test to compile on Intel.
-
- The gcc command line "-mindirect-branch' is an Intel specific and will give
- an error on other platforms. A check for X86 is added so the test will
- only run on X86 platforms.

- with no regressions.

- Fix "until LINE" in main, when "until" runs into longjmp
- With a test like this:
-
- 1 #include <dlfcn.h>
- 2 int
- 3 main ()
- 4 {
- 5 dlsym (RTLD_DEFAULT, "FOO");
- 6 return 0;
- 7 }
-
- and then "start" followed by "until 6", GDB currently incorrectly
- stops inside the runtime loader, instead of line 6. Vis:
-
- ...
- Temporary breakpoint 1, main () at until.c:5
- 4 {
- (gdb) until 6
- 0x00007ffff7f0a90d in __GI__dl_catch_exception (exception=exception@entry=0x7fffffffdb00, operate=<optimized out>, args=0x7ffff7f0a90d <__GI__dl_catch_exception+109>) at dl-error-skeleton.c:206
- 206 dl-error-skeleton.c: No such file or directory.
- (gdb)
-
- The problem is related to longjmp handling -- dlsym internally
- longjmps on error. The testcase can be reduced to this:
-
- 1 #include <setjmp.h>
- 2 void func () {
- 3 jmp_buf buf;
- 4 if (setjmp (buf) == 0)
- 5 longjmp (buf, 1);
- 6 }
- 7
- 8 int main () {
- 9 func ();
- 10 return 0; /* until to here */
- 11 }
-
- and then with "start" followed by "until 10", GDB currently
- incorrectly stops at line 4 (returning from setjmp), instead of line
- 10.
-
- The problem is that the BPSTAT_WHAT_CLEAR_LONGJMP_RESUME code in
- infrun.c fails to find the initiating frame, and so infrun thinks that
- the longjmp jumped somewhere outer to "until"'s originating frame.
-
- Here:
-
- case BPSTAT_WHAT_CLEAR_LONGJMP_RESUME:
- {
- struct frame_info *init_frame;
-
- /* There are several cases to consider.
-
- 1. The initiating frame no longer exists. In this case we
- must stop, because the exception or longjmp has gone too
- far.
-
- ...
-
- init_frame = frame_find_by_id (ecs->event_thread->initiating_frame);
-
- if (init_frame) // this is NULL!
- {
- ...
- }
-
- /* For Cases 1 and 2, remove the step-resume breakpoint, if it
- exists. */
- delete_step_resume_breakpoint (ecs->event_thread);
-
- end_stepping_range (ecs); // case 1., so we stop.
- }
-
- The initiating frame is set by until_break_command ->
- set_longjmp_breakpoint. The initiating frame is supposed to be the
- frame that is selected when the command was issued, but
- until_break_command instead passes the frame id of the _caller_ frame
- by mistake. When the "until LINE" command is issued from main, the
- caller frame is the caller of main. When later infrun tries to find
- that frame by id, it fails to find it, because frame_find_by_id
- doesn't unwind past main.
-
- The bug is that we passed the caller frame's id to
- set_longjmp_breakpoint. We should have passed the selected frame's id
- instead.

-
- Looking at the properties of the lang field, unlike dwarf_version it's
- not available in the unit header, so it will be set the first time
- during the parallel cooked index reading. The same holds for
- unit_type, and likewise for addresses_seen.
-
- dwarf2_per_cu_data::addresses_seen is moved so that the bitfields that
- currently follow it can be merged in the same memory location as the
- bitfields that currently precede it, for better packing.

-
- Introduce struct packed template
- When building gdb with -fsanitize=thread and gcc 12, and running test-case
- gdb.dwarf2/dwz.exp, we run into a few data races. For example, between:
-
- ...
- Write of size 1 at 0x7b200000300e by thread T4:
- #0 process_psymtab_comp_unit gdb/dwarf2/read.c:6789 (gdb+0x830720)
- ...
-
- and:
-
- ...
- Previous read of size 1 at 0x7b200000300e by main thread:
- #0 cutu_reader::cutu_reader(dwarf2_per_cu_data*, dwarf2_per_objfile*, \
- abbrev_table*, dwarf2_cu*, bool, abbrev_cache*) gdb/dwarf2/read.c:6164 \
- (gdb+0x82edab)
- ...
-
- In other words, between:
-
- ...
- this_cu->unit_type = DW_UT_partial;
- ...
-
- and:
-
- ...
- if (this_cu->reading_dwo_directly)
- ...
-
- The problem is that the written fields are part of the same memory
- location as the read fields, so executing a read and write in
- different threads is undefined behavour.
-
- Making the written fields separate memory locations, like this:
-
- ...
- struct {
- ENUM_BITFIELD (dwarf_unit_type) unit_type : 8;
- };
- ...
-
- fixes it, however that also increases the size of struct
- dwarf2_per_cu_data, because it introduces padding due to alignment of
- these new structs, which align on the natural alignment of the
- specified type of their fields. We can fix that with
- __attribute__((packed)), like so:
-
- struct {
- ENUM_BITFIELD (dwarf_unit_type) unit_type : 8 __attribute__((packed));
- };
-
- but to avoid having to write that in several places and add suitable
- comments explaining how that concoction works, introduce a new struct
- packed template that wraps/hides this. Instead of the above, we'll be
- able to write:
-
- packed<dwarf_unit_type, 1> unit_type;
-
- Note that we can't change the type of dwarf_unit_type, as that is
- defined in include/, and shared with other projects, some of those
- written in C.
-
- This patch just adds the struct packed type. Following patches will
- make use of it. One of those patches will want to wrap a struct
- packed in an std::atomic, like:
-
- std::atomic<std::packed<language, 1>> m_lang;
-
- so the new gdbsupport/packed.h header adds some operators to make
- comparisions between that std::atomic and the type that the wrapped
- struct packed wraps work, like in:
-
- if (m_lang == language_c)
-
- It would be possible to implement struct packed without using
- __attribute__((packed)), by having it store an array of bytes of the
- appropriate size instead, however that would make it less convenient
- to debug GDB. The way it's implemented, printing a struct packed
- variable just prints its field using its natural type, which is
- particularly useful if the type is an enum. I believe that
- __attribute__((packed)) is supported by all compilers that are able to
- build GDB. Even a few BFD headers use on ATTRIBUTE_PACKED on external
- types:
-
- include/coff/external.h: } ATTRIBUTE_PACKED
- include/coff/external.h:} ATTRIBUTE_PACKED ;
- include/coff/external.h:} ATTRIBUTE_PACKED ;
- include/coff/pe.h:} ATTRIBUTE_PACKED ;
- include/coff/pe.h:} ATTRIBUTE_PACKED;
- include/elf/external.h:} ATTRIBUTE_PACKED Elf_External_Versym;
-
- It is not possible to build GDB with MSVC today, but if it could, that
- would be one compiler that doesn't support this attribute. However,
- it supports packing via pragmas, so there's a way to cross that bridge
- if we ever get to it. I believe any compiler worth its salt supports
- some way of packing.
-
- In any case, the worse that happens without the attribute is that some
- types become larger than ideal. Regardless, I've added a couple
- static assertions to catch such compilers in action:
-
- /* Ensure size and aligment are what we expect. */
- gdb_static_assert (sizeof (packed) == Bytes);
- gdb_static_assert (alignof (packed) == 1);

- PR29355, ld segfaults with -r/-q and custom-named section .rela*
- The bug testcase uses an output section named .rel or .rela which has
- input .data sections mapped to it. The input .data section has
- relocations. When counting output relocations SHT_REL and SHT_RELA
- section reloc_count is ignored, with the justification that reloc
- sections themselves can't have relocations and some backends use
- reloc_count in reloc sections. However, the test wrongly used the
- output section type (which normally would match input section type).
- Fix that. Note that it is arguably wrong for ld to leave the output

- Always emit =thread-exited notifications, even if silent
- [Note: the testcased added by this commit depends on
- https://sourceware.org/pipermail/gdb-patches/2022-June/190259.html,
- otherwise GDB just crashes when detaching the core]
-
- Currently, in MI, =thread-created are always emitted, like:
-
- =thread-group-started,id="i1",pid="195680"
- =thread-created,id="1",group-id="i1"
- ...
-
- but on teardown, if the target uses exit_inferior_silent, then you'll
- only see the inferior exit notification (thread-group-exited), no
- notification for threads.
-
- The core target is one of the few targets that use
- exit_inferior_silent. Here's an example session:
-
- -target-select core $corefile
- =thread-group-started,id="i1",pid="195680"
- =thread-created,id="1",group-id="i1"
- ...
- ^connected,frame=....
- (gdb)
- -target-detach
- =thread-group-exited,id="i1"
- ^done
- (gdb)
-
- This imbalance of emitting =thread-created but then not =thread-exited
- seems off to me. (And, it complicates changes I want to do to
- centralize emitting thread exit notifications for the CLI, which is
- why I'm looking at this.)
-
- And then, since most other targets use exit_inferior instead of
- exit_inferior_silent, MI is already emitting =thread-exited
- notifications when tearing down an inferior, for most targets.
-
- This commit makes MI always emit the =thread-exited notifications,
- even for exit_inferior_silent.
-
- Afterwards, when debugging a core, MI outputs:
-
- (gdb)
- -target-detach
- =thread-exited,id="1",group-id="i1" << new line
- =thread-group-exited,id="i1"
- ^done
- (gdb)
-
- Surprisingly, there's no MI testcase debugging a core file. This

- {
- process_stratum_target *proc_target = inf->process_target ();
-
- if (proc_target->commit_resumed_state)
- ^^^^^^^^^^^
-
- With 'proc_target' above being null. all_non_exited_inferiors filters
- out inferiors that have pid==0. We get here at the end of
- detach_command, after core_target::detach has already run, at which
- point the inferior _should_ have pid==0 and no process target. It is
- clear it no longer has a process target, but, it still has a pid!=0
- somehow.
-
- The reason the inferior still has pid!=0, is that core_target::detach
- just unpushes, and relies on core_target::close to actually do the
- getting rid of the core and exiting the inferior. The problem with
- that is that detach_command grabs an extra strong reference to the
- process stratum target, so the unpush_target inside
- core_target::detach doesn't actually result in a call to
- core_target::close.
-
- Fix this my moving the cleaning up the core inferior to a shared
- routine called by both core_target::close and core_target::detach. We
- still need to cleanup the inferior from within core_file::close
- because there are paths to it that want to get rid of the core without
- going through detach. E.g., "core-file" -> "run".
-
- This commit includes a new test added to gdb.base/corefile.exp to
- cover the "core-file core" -> "detach" scenario.

- gdb: add support for disassembler styling using libopcodes
- This commit extends GDB to make use of libopcodes styling support
- where available, currently this is just i386 based architectures, and
- RISC-V.
-
- For architectures that don't support styling using libopcodes GDB will
- fall back to using the Python Pygments package, when the package is
- available.
-
- The new libopcodes based styling has the disassembler identify parts
- of the disassembled instruction, e.g. registers, immediates,
- mnemonics, etc, and can style these components differently.
- Additionally, as the styling is now done in GDB we can add settings to
- allow the user to configure which colours are used right from the GDB
- CLI.
-
- There's some new maintenance commands:
-
- maintenance set libopcodes-styling enabled on|off
- maintenance show libopcodes-styling
-
- These can be used to manually disable use of libopcodes styling. This
- is a maintenance command as it's not anticipated that a user should
- need to do this. But, this could be useful for testing, or, in some
- rare cases, a user might want to override the Python hook used for
- disassembler styling, and then disable libopcode styling so that GDB
- falls back to using Python. Right now I would consider this second
- use case a rare situation, which is why I think a maintenance command
- is appropriate.
-
- When libopcodes is being used for styling then the user can make use
- of the following new styles:
-
- set/show style disassembler comment
- set/show style disassembler immediate
- set/show style disassembler mnemonic
- set/show style disassembler register
-
- The disassembler also makes use of the 'address' and 'function'
- styles to style some parts of the disassembler output. I have also
- added the following aliases though:
-
- set/show style disassembler address
- set/show style disassembler symbol
-
- these are aliases for:
-
- set/show style address
- set/show style function
-
- respectively, and exist to make it easier for users to discover
- disassembler related style settings. The 'address' style is used to
- style numeric addresses in the disassembler output, while the 'symbol'
- or 'function' style is used to style the names of symbols in
- disassembler output.
-
- As not every architecture supports libopcodes styling, the maintenance
- setting 'libopcodes-styling enabled' has an "auto-off" type behaviour.
- Consider this GDB session:
-
- (gdb) show architecture
- The target architecture is set to "auto" (currently "i386:x86-64").
- (gdb) maintenance show libopcodes-styling enabled
- Use of libopcodes styling support is "on".
-
- the setting defaults to "on" for architectures that support libopcodes
- based styling.
-
- (gdb) set architecture sparc
- The target architecture is set to "sparc".
- (gdb) maintenance show libopcodes-styling enabled
- Use of libopcodes styling support is "off" (not supported on architecture "sparc")
-
- the setting will show as "off" if the user switches to an architecture
- that doesn't support libopcodes styling. The underlying setting is
- still "on" at this point though, if the user switches back to
- i386:x86-64 then the setting would go back to being "on".
-
- (gdb) maintenance set libopcodes-styling enabled off
- (gdb) maintenance show libopcodes-styling enabled
- Use of libopcodes styling support is "off".
-
- now the setting is "off" for everyone, even if the user switches back
- to i386:x86-64 the setting will still show as "off".
-
- (gdb) maintenance set libopcodes-styling enabled on
- Use of libopcodes styling not supported on architecture "sparc".
- (gdb) maintenance show libopcodes-styling enabled
- Use of libopcodes styling support is "off".
-
- attempting to switch the setting "on" for an unsupported architecture
- will give an error, and the setting will remain "off".
-
- (gdb) set architecture auto
- The target architecture is set to "auto" (currently "i386:x86-64").
- (gdb) maintenance show libopcodes-styling enabled
- Use of libopcodes styling support is "off".
- (gdb) maintenance set libopcodes-styling enabled on
- (gdb) maintenance show libopcodes-styling enabled
- Use of libopcodes styling support is "on".
-
- the user will need to switch back to a supported architecture before
- they can one again turn this setting "on".

- gdb: have gdb_disassemble_info carry 'this' in its stream pointer
- The gdb_disassemble_info class is a wrapper around the libopcodes
- disassemble_info struct. The 'stream' field of disassemble_info is
- passed as an argument to the fprintf_func and fprintf_styled_func
- callbacks when the disassembler wants to print anything.
-
- Previously, GDB would store a pointer to a ui_file object in the
- 'stream' field, then, when the disassembler wanted to print anything,
- the content would be written to the ui_file object. An example of an
- fprintf_func callback, from gdb/disasm.c is:
-
- int
- gdb_disassembler::dis_asm_fprintf (void *stream, const char *format, ...)
- {
- /* Write output to STREAM here. */
- }
-
- This is fine, but has one limitation, within the print callbacks we
- only have access to STREAM, we can't access any additional state
- stored within the gdb_disassemble_info object.
-
- Right now this isn't a problem, but in a future commit this will
- become an issue, how we style the output being written to STREAM will
- depend on the state of the gdb_disassemble_info object, and this state
- might need to be updated, depending on what is being printed.
-
- In this commit I propose changing the 'stream' field of the
- disassemble_info to carry a pointer to the gdb_disassemble_info
- sub-class, rather than the stream itself.
-
- We then have the two sub-classes of gdb_disassemble_info to consider,
- the gdb_non_printing_disassembler class never cared about the stream,
- previously, for this class, the stream was nullptr. With the change
- to make stream be a gdb_disassemble_info pointer, no further updates
- are needed for gdb_non_printing_disassembler.
-
- The other sub-class is gdb_printing_disassembler. In this case the
- sub-class now carries around a pointer to the stream object. The
- print callbacks are updated to cast the incoming stream object back to
- a gdb_printing_disassembler, and then extract the stream.
-
- This is purely a refactoring commit. A later commit will add
- additional state to the gdb_printing_disassembler, and update the
- print callbacks to access this state.
-
- There should be no user visible changes after this commit.

- [gdb/symtab] Fix data race in per_cu->length

- #0 cutu_reader::cutu_reader(dwarf2_per_cu_data*, dwarf2_per_objfile*, \

- (gdb+0x86e22e)^M
- ...
-
- In other words, between this write:
- ...
- this_cu->length = cu->header.get_length ();
- ...
- and this read:
- ...
- && mid_cu->sect_off + mid_cu->length > sect_off))
- ...
- of per_cu->length.
-
- Fix this similar to the per_cu->dwarf_version case, by only setting it if
- needed, and otherwise verifying that the same value is used. [ Note that the
- same code is already present in the other cutu_reader constructor. ]
-
- Move this logic into into a member function set_length to make sure it's used
- consistenly, and make the field private in order to enforce access through the
- member functions, and rename it to m_length.
-
- This exposes (running test-case gdb.dwarf2/fission-reread.exp) that in
- fill_in_sig_entry_from_dwo_entry, the m_length field is overwritten.
- For now, allow for that exception.
-
- While we're at it, make sure that the length is set before read.
-
- Tested on x86_64-linux.

- gas: tc-tic54x.c hash tables
- Cleaning up the subsym_hash memory is a real pain. Keys and values
- entered into the table are quite diverse. In some cases the key is
- allocated and thus needs to be freed, in others the key is a const
- string. Values are similar, and in some cases not even a string.
- Tidy this by inserting a new subsym_ent_t that describes key/value
- type. This meant the math_hash table was no longer needed. The patch
- also tidies how math functions are called, those that are supposed to
- return int now no longer return their value in a float.

- gas: use notes_calloc in string hash
- Using notes_calloc means all of the string hash table memory should
- now be freed before gas exits, even though htab_delete isn't called.
- This also means that the hash table free_f and del_f must be NULL,
- because freeing notes obstack memory results in all more recently
- allocated notes memory being freed too. So hash table resizing won't
- free any memory, and will be a little faster. Also, htab_delete won't
- do anything (and be quick about it).
-
- Since htab_traverse can also resize hash tables (to make another
- traversal faster if the table is largely empty), stop that happening
- when only one traversal is done.

- gas: rename md_end to md_finish
- Currently md_end is typically used for some final actions rather than
- freeing memory like other *_end functions. Rename it to md_finish,
- and rename target implementation. The renaming of target functions
- makes it possible to find them all with "grep md_finish",
- eg. md_mips_end is renamed to mips_md_finish, not md_mips_finish.
- This patch leaves a number of md_end functions unchanged, those that
- either do nothing or deallocate memory, and calls them late.
-
- The idea here is that target maintainers implement md_end functions to
- tidy memory, if anyone cares. Freeing persistent memory in gas is
- not at all important, except that it can hide more important memory
- leaks, those that happen once per some frequent gas operation, amongst

-
- checking that generated files are newer than configure... configure.ac:26: error: version mismatch. This is Automake 1.15.1,

- configure.ac:26: comes from Automake 1.16.5. You should recreate
- configure.ac:26: aclocal.m4 with aclocal and run automake again.
- WARNING: 'automake-1.15' is probably too old.

-
- Note that we don't limit the usage of the variable to guile versions <= 3.0.5,

- libopcodes/s390: add support for disassembler styling
- This commit adds disassembler style to the libopcodes s390

- added an appropriate style.
-
- For testing the new styling I just assembled then disassembled the
- source files in gas/testsuite/gas/s390 and manually checked that the
- styling looked reasonable.
-
- If the user does not request styled output from objdump, then there
- should be no change in the disassembler output after this commit.

- ---------------------
- ../../src/binutils-gdb/gdb/inferior.c:304: internal-error: find_inferior_pid: Assertion `pid != 0' failed.
- A problem internal to GDB has been detected,
- further debugging may prove unreliable.
- Quit this debugging session? (y or n)
-
- This is due to some bit-rot in the AIX port, still relying on the entry
- value of inferior_ptid in the wait methods.
-
- Problem #1 is in rs6000_nat_target::wait, here:
-
- /* Ignore terminated detached child processes. */
- if (!WIFSTOPPED (status) && pid != inferior_ptid.pid ())
- pid = -1;
-
- At this point, waitpid has returned an "exited" status for some pid, so
- pid is non-zero. Since inferior_ptid is set to null_ptid on entry, the
- pid returned by wait is not equal to `inferior_ptid.pid ()`, so we reset
- pid to -1 and go to waiting again. Since there are not more children to
- wait for, waitpid then returns -1 so we get here:
-
- if (pid == -1)
- {
- gdb_printf (gdb_stderr,
- _("Child process unexpectedly missing: %s.\n"),
- safe_strerror (save_errno));
-
- /* Claim it exited with unknown signal. */
- ourstatus->set_signalled (GDB_SIGNAL_UNKNOWN);
- return inferior_ptid;
- }
-
- We therefore return a "signalled" status with a null_ptid (again,
- inferior_ptid is null_ptid). This confuses infrun, because if the
- target returns a "signalled" status, it should be coupled with a ptid
- for an inferior that exists.
-
- So, the first step is to fix the snippets above to not use
- inferior_ptid. In the first snippet, use find_inferior_pid to see if
- we know the event process. If there is no inferior with that pid, we
- assume it's a detached child process to we ignore the event. That
- should be enough to fix the problem, because it should make it so we
- won't go into the second snippet. But still, fix the second snippet to
- return an "ignore" status. This is copied from inf_ptrace_target::wait,
- which is where rs6000_nat_target::wait appears to be copied from in the
- first place.
-
- These changes, are not sufficient, as the aix_thread_target, which sits
- on top of rs6000_nat_target, also relies on inferior_ptid.
- aix_thread_target::wait, by calling pd_update, assumes that
- rs6000_nat_target has set inferior_ptid to the appropriate value (the
- ptid of the event thread), but that's not the case. pd_update
- returns inferior_ptid - null_ptid - and therefore
- aix_thread_target::wait returns null_ptid too, and we still hit the
- assert shown above.
-
- Fix this by changing pd_activate, pd_update, sync_threadlists and
- get_signaled_thread to all avoid using inferior_ptid. Instead, they
- accept as a parameter the pid of the process we are working on.
-
- With this patch, I am able to run the program to completion:

- Fix pedantically invalid DWARF in gdb.trace/unavailable-dwarf-piece.exp
- The DWARF spec says:
-
- Any debugging information entry representing the declaration of an object,
- module, subprogram or type may have DW_AT_decl_file, DW_AT_decl_line and
- DW_AT_decl_column attributes, each of whose value is an unsigned integer
- ^^^^^^^^
- constant.
-
- Grepping around the DWARF-assembler-based testcases, I noticed that
- gdb.trace/unavailable-dwarf-piece.exp emits decl_line with
- DW_FORM_sdata, a signed integer form. This commit tweaks it to use
- DW_FORM_udata instead.
-
- Unsurprisingly, this:
-
- $ make check \
- TESTS="gdb.trace/unavailable-dwarf-piece.exp" \
- RUNTESTFLAGS="--target_board=native-gdbserver"
-
- ... still passes cleanly for me after this change.
-
- I've noticed this because current llvm-dwarfdump crashed on an
- ROCm-internal DWARF-assembler-based testcase that incorrectly used
- signed forms for DW_AT_decl_file/DW_AT_decl_line.
-
- The older llvm-dwarfdump found on Ubuntu 20.04 (LLVM 10) reads the
- line numbers with signed forms as "0" instead of crashing. Here's the
- before/after fix for gdb.trace/unavailable-dwarf-piece.exp with that
- llvm-dwarfdump version:

- x86: make D attribute usable for XOP and FMA4 insns
- This once again allows to reduce redundancy in (and size of) the opcode
- table.
-
- Don't go as far as also making D work on the two 5-operand XOP insns:
- This would significantly complicate the code, as there the first
- (immediate) operand would need special treatment in several places.
-
- Note that the .s suffix isn't being enabled to have any effect, for
- being deprecated. Whereas neither {load} nor {store} pseudo prefixes
- make sense here, as the respective operands are inputs (loads) only
- anyway, regardless of order. Hence there is (as before) no way for the
- programmer to request the alternative encoding to be used for register-
- only insns.
-
- Note further that it is always the first original template which is
- retained (and altered), to make sure the same encoding as before is
- used for register-only insns. This has the slightly odd (but pre-
- existing) effect of XOP register-only insns having XOP.W clear, but FMA4
- ones having VEX.W set.

- vmovss %xmm0, %esp, %xmm2
-
- to assemble successfully, or e.g.
-
- vmovss %xmm0, $4, %xmm2
-
- causing an internal error. Alongside dealing with this also drop a
- related comment, which hasn't been applicable anymore since the
- introduction of 3-operand patterns with D set (and which perhaps never
- had been logical to be there, as reverse-matched insns don't make it
- there in the first place).

- x86: introduce a state stack for .arch
- When using just slightly non-trivial combinations of .arch, it can be
- quite useful to be able to go back to prior state without needing to
- re-invoke perhaps many earlier directives and without needing to invoke
- perhaps many "negative" ones. Like some other architectures allow
- saving (pushing) and restoring (popping) present/prior state.
-
- For now require the same .code<N> to be in effect for ".arch pop" that
- was in effect for the corresponding ".arch push".

- Also change the global "no_cond_jump_promotion" to be bool, to match the
- new struct field.

- So far there was no way to reset the architecture to that assembly would

- Note that for Intel MCU "default" is merely an alias of "iamcu".
-
- While there also zap a stray @item from the doc section, as noticed
- when inspecting the generated output (which still has some quirks, but
- those aren't easy to address without re-flowing almost the entire
- section).

- gdb: LoongArch: add orig_a0 into register set
- The basic support for LoongArch has been merged into the upstream Linux
- kernel since 5.19-rc1 on June 5, 2022. This commit adds orig_a0 which
- is added into struct user_pt_regs [1] to match the upstream kernel, and
- then the upstream GDB will work with the upstream kernel.
-
- Note that orig_a0 was added into struct user_pt_regs in the development
- cycle for merging LoongArch port into the upstream Linux kernel, so
- earlier kernels (notably, the product kernel with version 4.19 used in
- distros like UOS and Loongnix) don't have it. Inspect
- arch/loongarch/include/uapi/asm/ptrace.h in the kernel tree to make sure.
- To build upstream GDB for a kernel lacking orig_a0, it's necessary to
- revert this commit locally.

- x86: fold Disp32S and Disp32
- The only case where 64-bit code uses non-sign-extended (can also be
- considered zero-extended) displacements is when an address size override
- is in place for a memory operand (i.e. particularly excluding
- displacements of direct branches, which - if at all - are controlled by
- operand size, and then are still sign-extended, just from 16 bits).
- Hence the distinction in templates is unnecessary, allowing code to be
- simplified in a number of places. The only place where logic becomes
- more complicated is when signed-ness of relocations is determined in
- output_disp().
-
- The other caveat is that Disp64 cannot be specified anymore in an insn
- template at the same time as Disp32. Unlike for non-64-bit mode,
- templates don't specify displacements for both possible addressing
- modes; the necessary adjustment to the expected ones has already been
- done in match_template() anyway (but of course the logic there needs
- tweaking now). Hence the single template so far doing so is split.

- x86: restore masking of displacement kinds
- Commit 7d5e4556a375 rendered the check near the end of what is now
- i386_finalize_displacement() entirely dead for AT&T mode, since for
- operands involving a displacement .unspecified will always be set. But
- the logic there is bogus anyway - Intel syntax operand size specifiers
- are of no interest there either. The only thing which matters in the
- "displacement only" determination is .baseindex.
-
- Of course when masking displacement kinds we should not at the same time
- also mask off other attributes.
-
- Furthermore the type mask returned by lex_got() also needs to be
- adjusted: The only case where we want Disp32 (rather than Disp32S) is
- when dealing with 32-bit addressing mode in 64-bit code.

- point not too long ago I'm afraid it may have been me who regressed the
- relocation addends emitted for such branches. Correct both problems,

- Fix this by setting the field earlier, in read_comp_units_from_section.
-
- The write in cutu_reader::cutu_reader() is still needed, in case
- read_comp_units_from_section is not used (run the test-case with say, target
- board cc-with-gdb-index).
-
- Make the write conditional, such that it doesn't trigger if the field is
- already set by read_comp_units_from_section. Instead, verify that the
- field already has the value that we're trying to set it to.
-
- Move this logic into into a member function set_version (in analogy to the
- already present member function version) to make sure it's used consistenly,
- and make the field private in order to enforce access through the member
- functions, and rename it to m_dwarf_version.
-
- While we're at it, make sure that the version is set before read, to avoid
- say returning true for "per_cu.version () < 5" if "per_cu.version () == 0".

- GDB/doc: Remove extraneous spaces from completion examples
- Completion results are usually different when the operation is applied
- to a word that is or is not followed by a space. In some cases they are
- equivalent, however a space would not be produced if completion was used
- earlier on in the word processed.
-
- However in the manual we have completion examples given using a space
- that actually prevents the example from working. E.g.:
-
- (gdb) info bre <TAB>
-
- (nothing) and:
-
- (gdb) info bre <TAB><TAB>
- Display all 200 possibilities? (y or n)
-
- as it now goes on to propose the entire symbol table, while:
-
- (gdb) info bre<TAB>
- (gdb) info breakpoints
-
- does the right thing, but is not what is shown in the manual.
-
- In other cases an extraneous space is used that does not correspond to
- the actual completion pattern shown, which gives an impression of
- sloppiness.
-
- Remove extraneous spaces then from completion examples as appropriate.

- GDB: Add `NUMBER' completion to `set' integer commands
- Fix a completion consistency issue with `set' commands accepting integer
- values and the special `unlimited' keyword:
-
- (gdb) complete print -elements
- print -elements NUMBER
- print -elements unlimited
- (gdb)
-
- vs:
-
- (gdb) complete set print elements
- set print elements unlimited
- (gdb)
-
- (there is a space entered at the end of both commands, not shown here)
- which also means if you strike <Tab> with `set print elements ' input,
- it will, annoyingly, complete to `set print elements unlimited' right
- away rather than showing a choice between `NUMBER' and `unlimited'.
-
- Add `NUMBER' then as an available completion for such `set' commands:
-
- (gdb) complete set print elements
- set print elements NUMBER
- set print elements unlimited
- (gdb)
-
- Adjust the testsuite accordingly. Also document the feature in the
- Completion section of the manual in addition to the Command Options
- section already there.

-
- Above we see that in the non-existing-program case, the process gets
- deleted before the starting_up flag gets restored to false.
-
- This happens because startup_inferior calls target_mourn_inferior
- before throwing an error, and in GDBserver, unlike in GDB, mourning
- deletes the process.
-
- Fix this by not using a scoped_restore to manage the starting_up flag,
- since we should only clear it when startup_inferior doesn't throw.

- opcodes/aarch64: split off creation of comment text in disassembler
- The function aarch64_print_operand (aarch64-opc.c) is responsible for
- converting an instruction operand into the textual representation of
- that operand.
-
- In some cases, a comment is included in the operand representation,
- though this (currently) only happens for the last operand of the
- instruction.
-
- In a future commit I would like to enable the new libopcodes styling
- for AArch64, this will allow objdump and GDB[1] to syntax highlight
- the disassembler output, however, having operands and comments
- combined in a single string like this makes such styling harder.
-
- In this commit, I propose to extend aarch64_print_operand to take a
- second buffer. Any comments for the instruction are written into this
- extra buffer. The two callers of aarch64_print_operand are then
- updated to pass an extra buffer, and print any resulting comment.
-
- In this commit no styling is added, that will come later. However, I
- have adjusted the output slightly. Before this commit some comments
- would be separated from the instruction operands with a tab character,
- while in other cases the comment was separated with two single spaces.
-
- After this commit I use a single tab character in all cases. This
- means a few test cases needed updated. If people would prefer me to
- move everyone to use the two spaces, then just let me know. Or maybe
- there was a good reason why we used a mix of styles, I could probably
- figure out a way to maintain the old output exactly if that is
- critical.
-
- Other than that, there should be no user visible changes after this
- commit.

- gdb/testsuite: fix gdb.base/break-idempotent.exp on ppc
- When running the gdb.base/break-idempotent.exp test on ppc, I was
- seeing some test failures (or rather errors), that looked like this:
-
- (gdb) watch local
- Hardware watchpoint 2: local
-
- has_hw_wp_support: Hardware watchpoint detected
- ERROR: no fileid for gcc2-power8
- ERROR: Couldn't send delete breakpoints to GDB.
- ERROR OCCURED: can't read "gdb_spawn_id": no such variable
- while executing
- "expect {
- -i 1000 -timeout 100
- -re ".*A problem internal to GDB has been detected" {
- fail "$message (GDB internal error)"
- gdb_internal_erro..."
- ("uplevel" body line 1)
- invoked from within
-
- What happens is that in break-idempotent.exp we basically do this:
-
- if {[prepare_for_testing "failed to prepare" $binfile $srcfile $opts]} {
- continue
- }
-
- # ....
-
- if {![skip_hw_watchpoint_tests]} {
- test_break $always_inserted "watch"
- }
-
- The problem with this is that skip_hw_watchpoint_tests, includes this:
-
- if { [istarget "i?86-*-*"]
- || [istarget "x86_64-*-*"]
- || [istarget "ia64-*-*"]
- || [istarget "arm*-*-*"]
- || [istarget "aarch64*-*-*"]
- || ([istarget "powerpc*-*-linux*"] && [has_hw_wp_support])
- || [istarget "s390*-*-*"] } {
- return 0
- }
-
- For powerpc only we call has_hw_wp_support. This is a caching proc
- that runs a test within GDB to detect if we have hardware watchpoint
- support or not.
-
- Unfortunately, to run this test we restart GDB, and when the test has
- completed, we exit GDB. This means that in break-idempotent.exp, when
- we call skip_hw_watchpoint_tests for the first time on powerpc, GDB
- will unexpectedly be exited. When we later call delete_breakpoints we
- see the errors I reported above.
-
- The fix is to call skip_hw_watchpoint_tests early, before we start GDB
- as part of the break-idempotent.exp script, and store the result in a
- variable, we can then check this variable in the script as needed.
-
- After this change break-idempotent.exp runs fine on powerpc.

- gdb+gdbserver/Linux: avoid reading registers while going through shell
- For every stop, Linux GDB and GDBserver save the stopped thread's PC,
- in lwp->stop_pc. This is done in save_stop_reason, in both
- gdb/linux-nat.c and gdbserver/linux-low.cc. However, while we're
- going through the shell after "run", in startup_inferior, we shouldn't
- be reading registers, as we haven't yet determined the target's
- architecture -- the shell's architecture may not even be the same as
- the final inferior's.
-
- In gdb/linux-nat.c, lwp->stop_pc is only needed when the thread has
- stopped for a breakpoint, and since when going through the shell, no
- breakpoint is going to hit, we could simply teach save_stop_reason to
- only record the stop pc when the thread stopped for a breakpoint.
-
- However, in gdbserver/linux-low.cc, lwp->stop_pc is used in more cases
- than breakpoint hits (e.g., it's used in tracepoints & the
- "while-stepping" feature).
-
- So to avoid GDB vs GDBserver divergence, we apply the same approach to
- both implementations.
-
- We set a flag in the inferior (process in GDBserver) whenever it is
- being nursed through the shell, and when that flag is set,
- save_stop_reason bails out early. While going through the shell,
- we'll only ever get process exits (normal or signalled), random
- signals, and exec events, so nothing is lost.

- When building gdb with system gcc 7.5.0, I run into:
- ...
- gdb/ia64-tdep.c: In function ‘int is_float_or_hfa_type_recurse(type*, type**)’:
- gdb/ia64-tdep.c:3362:1: error: control reaches end of non-void function \
- [-Werror=return-type]
- ...
-
- This is due to PR gcc/81275 - "-fsanitize=thread produce incorrect
- -Wreturn-type warning", which has been fixed in gcc-8.
-
- Work around this by moving the default return outside the switch.
-
- Tested on x86_64-linux.

- gdb:csky add pseudo regs for float and vector regs
- In the existing CSKY architecture, there are at most 32 floating
- and 16 vector registers. Float registers's count can be configured
- as 16 or 32. In the future, the vector registers's count may be
- extended to 32.
-
- The bit width of floating-point register is 64bits, and the bit
- width of vector register is 128bit.
-
- Special points: in fr0~fr15 and vr0~vr15, each FRx is the lower
- 64 bits of the corresponding VRx.
-
- Here, we will split each floating-point and vector register to
- 32bits wide, add the corresponding pseudo registers, and finally
- use them for the dwarf registers.
-
- There are 128 pseudo registers in total, s0~s127, including:
- 1. s0 and s1 correspond to fr0, s4 and s5 correspond to fr1, and so on.
- Every two separated pseudo registers correspond to a float register.
- 2. s0, s1, s2 and s3 correspond to vr0; s4, s5, s6 and s7 correspond to vr1,
- and so on. Every four pseudo registers corresponds to a vector register.
-
- Therefore, in s64~s127, there are general registers that are not actually
- used. This part is to prepare for the expansion of vector registers to 32
-
- Therefore, in s64~s127, half of the registers are actually unused. This
- part is to prepare for the expansion of the vector register to 32.

- Make GDBserver abort on internal error in development mode
- Currently, if GDBserver hits some internal assertion, it exits with
- error status, instead of aborting. This makes it harder to debug
- GDBserver, as you can't just debug a core file if GDBserver fails an
- assertion. I've had to hack the code to make GDBserver abort to debug
- something several times before.
-
- I believe the reason it exits instead of aborting, is to prevent
- potentially littering the filesystem of smaller embedded targets with
- core files. I think I recall Daniel Jacobowitz once saying that many
- years ago, but I can't be sure. Anyhow, that seems reasonable to me.
-
- Since we nowadays have a distinction between development and release
- modes, I propose to make GDBserver abort on internal error if in
- development mode, while keeping the status quo when in release mode.
-
- Thus, after this patch, in development mode, you get:
-
- $ ../gdbserver/gdbserver
- ../../src/gdbserver/server.cc:3711: A problem internal to GDBserver has been detected.
- captured_main: Assertion `0' failed.
- Aborted (core dumped)
- $
-
- while in release mode, you'll continue to get:
-
- $ ../gdbserver/gdbserver
- ../../src/gdbserver/server.cc:3711: A problem internal to GDBserver has been detected.
- captured_main: Assertion `0' failed.
- $ echo $?
- 1
-
- I do not think that this requires a separate configure switch.
-
- A "--target_board=native-extended-gdbserver" run on Ubuntu 20.04 ends
- up with:
-
- === gdb Summary ===
-
- # of unexpected core files 29
- ...
-
- for me, of which 8 are GDBserver core dumps, 7 more than without this
- patch.

- [gdb/symtab] Fix parsing of .debug_str_offsets header
- When running test-case gdb.dwarf2/fission-mix.exp with target board dwarf64
- and gcc-12 (defaulting to DWARF5), I run into:
- ...
- (gdb) break func2^M
- Offset from DW_FORM_GNU_str_index or DW_FORM_strx pointing outside of \
- .debug_str.dwo section in CU at offset 0x0 [in module fission-mix]^M
- (gdb) FAIL: gdb.dwarf2/fission-mix.exp: break func2
- ...
-
- The .debug_str_offsets section has version 5, so as per the standard it has
- it's own header, with initial length and version:
- ...
- Contents of the .debug_str_offsets.dwo section (loaded from fission-mix2.dwo):

- Length: 0x1c

- 0 0 build/gdb/testsuite
- 1 33 GNU C17
- 2 8f src/gdb/testsuite/gdb.dwarf2/fission-mix-2.c
- ...
-
- But when trying to read the string offset at index 0 in the table (which
- is 0), we start reading at offset 8, which points in the header, at the last
- 4 bytes of the initial length (it's 12 bytes because of 64-bit dwarf), as well
- at the 2-byte version field and 2 bytes of padding, so we get:
- ...
- (gdb) p /x str_offset
- $1 = 0x500000000
- ...
- which indeed is an offset that doesn't fit in the .debug_str section.
-
- The offset 8 is based on reader->cu->header.addr_size:
- ...
- static const char *
- read_dwo_str_index (const struct die_reader_specs *reader, ULONGEST str_index)
- {
- ULONGEST str_offsets_base = reader->cu->header.version >= 5
- ? reader->cu->header.addr_size : 0;
- ...
- which doesn't in look in agreement with the standard.

- Note that this happens to give the right answer for 32-bit dwarf and
- addr_size == 8, because then we have header size ==
- (initial length (4) + version (2) + padding (2)) == 8.
-
- Conversely, for 32-bit dwarf and addr_size == 4 (target board unix/-m32)
- we run into a similar problem. It just happens to not trigger the warning,
- instead we get the wrong strings, like "func2" for DW_AT_producer and
- "build/gdb/testsuite" for DW_AT_name of the DW_TAG_compile_unit DIE.
-
- Fix this by parsing the .debug_str_offsets header in read_dwo_str_index.
-
- Add a FIXME that we should not parse this for every call.
-
- Tested on x86_64-linux.

- [gdb/build] Fix gdbserver build with -fsanitize=thread
- [ Copied from gcc commit 153689603fd ("[gdb/build] Fix gdbserver build with
- -fsanitize=thread"). ]
-
- When building gdbserver with -fsanitize=thread (added to CFLAGS/CXXFLAGS) we
- run into:
- ...
- ld: ../libiberty/libiberty.a(safe-ctype.o): warning: relocation against \
- `__tsan_init' in read-only section `.text'
- ld: ../libiberty/libiberty.a(safe-ctype.o): relocation R_X86_64_PC32 \
- against symbol `__tsan_init' can not be used when making a shared object; \
- recompile with -fPIC
- ld: final link failed: bad value
- collect2: error: ld returned 1 exit status
- make[1]: *** [libinproctrace.so] Error 1
- ...
- which looks similar to what is described in commit 78e49486944 ("[gdb/build]
- Fix gdbserver build with -fsanitize=address").
-
- The gdbserver component builds a shared library libinproctrace.so, which uses
- libiberty and therefore requires the pic variant. The gdbserver Makefile is
- setup to use this variant, if available, but it's not there.
-
- Fix this by listing gdbserver in the toplevel configure alongside libcc1, as a
- component that needs the libiberty pic variant, setting:
- ...
- extra_host_libiberty_configure_flags=--enable-shared
- ...
-
- Tested on x86_64-linux.
-
- ChangeLog:
-

- PowerPC64 .branch_lt address
- .branch_lt is really an extension of .plt, as is .iplt. We'd like all
- of the PLT sections to be fixed relative to .TOC. after stub sizing,
- because changes in offset to PLT entries might mean a change in stub
- sizes. When -z relro, the relro layout does this by laying out
- sections from the end of the relro segment. So for example, a change
- in .eh_frame (which happens after stub sizing) will keep the same GOT
- to PLT offset when -z relro. Not so when -z norelro, because then the
- usual forward layout of section is done and .got is more aligned than
- .branch_lt.
-
- * emulparams/elf64ppc.sh: Set .branch_lt address fixed relative
- to .got.
- * testsuite/ld-powerpc/elfv2exe.d: Adjust to suit.

- -z relro relaxation and ld script SIZEOF
- A number of targets use assignments like:
- . = DATA_SEGMENT_RELRO_END (SIZEOF (.got.plt) >= 12 ? 12 : 0, .);
- (from i386) in linker scripts to put the end of the relro segment past
- the header in .got.plt. Examination of testcases like those edited by
- this patch instead sees the end of the relro segment being placed at
- the start of .got.plt. For the i386 pie1 test:
-
- [ 9] .got.plt PROGBITS 00002000 001000 00000c 04 WA 0 0 4

-
- The DATA_SEGMENT_RELRO_END value in the map file is weird too. All of

- Fix corrupt DWARF in dw2-double-set-die-type
- The dw2-double-set-die-type.exp test case caused an AddressSanitizer
- failure in the new DWARF scanner.
-
- The immediate cause was bad DWARF in the test -- in particular, the
- the sibling attribute here:
-
- <2><181>: Abbrev Number: 33 (DW_TAG_subprogram)
- <182> DW_AT_external : 1
- <183> DW_AT_name : address
- <18b> DW_AT_type : <0x171>

- <1a2> DW_AT_byte_size : 4
- <1a3> DW_AT_type : <0x1a7>
-
- ...points to a "sibling" DIE that is at a different child depth.
-
- Because this test case doesn't really require sibling attributes, this
- patch fixes the problem by removing them from the test.
-
- Note that gdb is not generally robust against malformed DWARF.
- Detecting and compensating for this problem would probably be
- expensive and, IMO, is better left to some (still hypothetical) DWARF
- linter.

- Eliminate TUI/CLI observers duplication
- For historical reasons, the CLI and the TUI observers are basically
- exact duplicates, except for the downcast:
-
- cli:
- struct cli_interp *cli = as_cli_interp (interp);
- tui:
- struct interp *tui = as_tui_interp (interp);
-
- and how they get at the interpreter's ui_out:
-
- cli:
- cli->cli_uiout
- tui:
- tui->interp_ui_out ()
-
- Since interp_ui_out() is a virtual method that also works for the CLI
- interpreter, and, both the CLI and the TUI interpreters inherit from
- the same base class (cli_interp_base), we can convert the CLI
- observers to cast to cli_interp_base instead and use interp_ui_out()
- too. With that, the CLI observers will work for the TUI interpreter
- as well. This lets us completely eliminate the TUI observers. That's
- what this commit does.

- gdb/testsuite: remove unneeded calls to get_compiler_info
- It is not necessary to call get_compiler_info before calling

- the gcc_compiled, true, and false globals from get_compiler_info,
- there is now no longer any need for any test script to call
- get_compiler_info directly.

- gdb/testsuite: remove global gcc_compiled from gdb.exp
- After this commit the gcc_compiled global is no longer exported from
- lib/gdb.exp. In theory we could switch over all uses of gcc_compiled
- to instead call test_compiler_info directly, however, I have instead
- added a new proc to gdb.exp: 'is_c_compiler_gcc'. I've then updated
- the testsuite to call this proc instead of using the global.
-
- Having a new proc specifically for this task means that we have a
- single consistent pattern for detecting gcc. By wrapping this logic
- within a proc that calls test_compiler_info, rather than using the
- global, means that test scripts don't need to call get_compiler_info
- before they read the global, simply calling the new proc does
- everything in one go.
-
- As a result I've been able to remove the get_compiler_info calls from
- all the test scripts that I've touched in this commit.
-
- In some of the tests e.g. gdb.dwarf2/*.exp, the $gcc_compiled flag was
- being checked at the top of the script to decide if the whole script
- should be skipped or not. In these cases I've called the new proc
- directly and removed all uses of gcc_compiled.
-
- In other cases, e.g. most of the gdb.base scripts, there were many
- uses of gcc_compiled. In these cases I set a new global gcc_compiled
- near the top of the script, and leave the rest of the script
- unchanged.
-
- There should be no changes in what is tested after this commit.

- Include count of unexpected core files in gdb.sum summary
- If GDB, GDBserver, a testcase program, Valgrind, etc. unexpectedly
- crash while running the GDB testsuite, and you've setup your machine
- such that core files are dumped in the current directory instead of
- being shoved somewhere by abrt, apport, or similar (as you should for
- proper GDB testing), you'll end up with an unexpected core file in the
- $build/gdb/testsuite/ directory.
-
- It can happen that GDB, GDBserver, etc. even crashes _after_ gdb_exit,
- during teardown, and thus such a crash won't be noticed by looking at
- the gdb.sum file at all. This commit aims at improving that, by
- including a new "unexpected core files" line in the testrun summary.
-
- For example, here's what I get on x86-64 Ubuntu 20.04, with this
- patch:
-
- === gdb Summary ===
-
- # of unexpected core files 12 << new info
- # of expected passes 107557
- # of unexpected failures 35
- # of expected failures 77
- # of unknown successes 2
- # of known failures 114
- # of untested testcases 31
- # of unsupported tests 139
-
- I have my core pattern setup like this:
-
- $ cat /proc/sys/kernel/core_pattern
- core.%e.%p.%h.%t
-
- That's:
-
- %e: executable filename
- %p: pid
- %h: hostname
- %t: UNIX time of dump
-
- and so I get these core files:
-
- $ ls -1 testsuite/core.*
- testsuite/core.connect-with-no.216191.nelson.1656002431
- testsuite/core.connect-with-no.217729.nelson.1656002431
- testsuite/core.gdb.194247.nelson.1656002423
- testsuite/core.gdb.226014.nelson.1656002435
- testsuite/core.gdb.232078.nelson.1656002438
- testsuite/core.gdb.352268.nelson.1656002441
- testsuite/core.gdb.4152093.nelson.1656002337
- testsuite/core.gdb.4154515.nelson.1656002338
- testsuite/core.gdb.4156668.nelson.1656002339
- testsuite/core.gdb.4158871.nelson.1656002341
- testsuite/core.gdb.468495.nelson.1656002444
- testsuite/core.vgdb.4192247.nelson.1656002366
-
- where we can see that GDB crashed a number of times, but also
- Valgrind's vgdb, and a couple testcase programs. Neither of which is
- good.
-
- If your core_pattern is just "core" (but why??), then I guess that you
- may end up with just a single core file in testsuite/. Still, that is
- one core file too many.
-
- Above, we see a couple cores for "connect-with-no", which are the
- result of gdb.server/connect-with-no-symbol-file.exp. This is a case
- mentioned above -- while the program crashed, that happens during
- testcase teardown, and it goes unnoticed (without this commit) by
- gdb.sum results. Vis:
-
- $ make check TESTS="gdb.server/connect-with-no-symbol-file.exp"
- ...
- === gdb Summary ===
-
- # of unexpected core files 2
- # of expected passes 8
-
- ...
- $
-
- The tests fully passed, but still the testcase program crashed
- somehow:
-
- $ ls -1 testsuite/core.*
- testsuite/core.connect-with-no.941561.nelson.1656003317
- testsuite/core.connect-with-no.941682.nelson.1656003317
-
- Against --target_board=native-extended-gdbserver it's even worse. I
- get:
-
- # of unexpected core files 26
-
- and note that when GDBserver hits an assertion failure, it exits with
- error, instead of crashing with SIGABRT. I think that should be
- changed, at least on development builds, but that would be for another
- patch. After such patch, I suspect the number of unexpected cores
- will be higher, as there are likely teardown GDBserver assertions that
- we're not noticing.
-
- I decided to put this new info in the "gdb Summary" section, as that's
- a place people already are used to looking at, either when looking at
- the tail of gdb.sum, or when diffing gdb.sum files, and we've already
- extended this section before, to include the count of DUPLICATE and
- PATH problems, so there's precedent.
-
- Implementation-wise, the new line is appended after DejaGnu is
- finished, with a shell script that is invoked by the Makefile. It is
- done this way so that serial and parallel testing work the same way.
- My initial cut at an implementation was in TCL, straight in
- testsuite/lib/check-test-names.exp, where DUPLICATES and PATH are
- handled, like so:
-
- @@ -148,6 +159,10 @@ namespace eval ::CheckTestNames {
- $counts(paths,$which)
- maybe_show_count "# of duplicate test names\t" \
- $counts(duplicates,$which)
- +
- + set cores [glob -nocomplain -directory $::objdir core*]
- + maybe_show_count "# of unexpected core files\t" \
- + [llength $cores]
- }
-
- But that would only work for serial testing, as in parallel testing,
- the final gdb.sum is generated by aggregating the results of all the
- individual gdb.sum files, and dg-extract-results.sh doesn't know about
- our new summary line. And I don't think that dg-extract-results.sh
- should be taught about it, since the count of core files is not
- something that we want to count many times, once per testcase, and
- then add up the subcounts at the end. Every time we count the core
- files, we're already counting the final count.
-
- I considered using the Tcl implementation in serial mode, and the
- script approach for parallel testing, but that has the obvious
- downside of implementing and maintaining the same thing twice. In the
- end, I settled on the script approach for serial mode too, which
- requires making the "check-single" rule print the tail end of the
- gdb.sum file, with a side effect being that if you look at the
- terminal after a run (instead of at the gdb.sum file), you'll see the
- "gdb Summary" section twice, once without the unexpected core lines
- printed, and then another with. IMO, this isn't an issue; when
- testing in parallel mode, if you look at the terminal after "make -jN
- check", you'll also see multiple "gdb Summary" sections printed.

- Improve core file path detection & put cores in output dir
- After a testrun, I noticed that I have some kernel-produced cores for
- testcase programs, under build/gdb/testsuite/, which shouldn't be
- there:
-
- $ ls -1 testsuite/core.*
- testsuite/core.annota1.1274351.nelson.1656004407
- testsuite/core.annota3.1288474.nelson.1656004414
- testsuite/core.exitsignal.1240674.nelson.1656004391
-
- I have my core pattern setup like this:
-
- $ cat /proc/sys/kernel/core_pattern
- core.%e.%p.%h.%t
-
- That's:
-
- %e: executable filename
- %p: pid
- %h: hostname
- %t: UNIX time of dump
-
- so it's easy to tell which program produced the core from the core
- file name.
-
- From above, we can tell that the corresponding testcases are
- gdb.base/annota1.exp, gdb.base/annota3.exp and
- gdb.base/exitsignal.exp.
-
- At least gdb.base/annota1.exp and gdb.base/annota3.exp have code in
- them to delete the core file. However, that isn't working for me,
- because said code only looks for cores named exactly either "core" or
- "core.PID", and my core_pattern doesn't match that.
-
- Another issue I noticed, is that I have not been running
- gdb.base/bigcore.exp, for a similar reason. I get:
-
- Program terminated with signal SIGABRT, Aborted.
- The program no longer exists.
- (gdb) PASS: gdb.base/bigcore.exp: signal SIGABRT
- UNTESTED: gdb.base/bigcore.exp: can't generate a core file
-
- But I actually have a core file under the testcase's output dir:
-
- $ find . -name "core.*"
- ./testsuite/outputs/gdb.base/bigcore/core.bigcore.2306705.nelson.1656005213
- $
-
- This commit fixes these things, by adding a find_core_file routine
- that searches core files in a way that works with my core pattern as
- well. This then also adds a convenience remove_core routine as a
- wrapper around find_core_file that removes the found core file.
-
- In addition, it changes some testcases that expect to have their
- program dump core, to switch the inferior's cwd to the testcase's
- output dir, so that the core is dumped there instead of in
- build/gdb/testsuite/. Some testcases were already doing that, but not
- all. The idea is that any core file dumped in build/gdb/testsuite/ is
- an unexpected core file. The next patch will add a count of such
- unexpected core files to gdb.sum.
-
- Another change is that the directory changing is now done with "set
- cwd" instead of with "cd". "set cwd" only affects the inferior cwd,
- while "cd" affects GDB's cwd too. By using "set cwd" instead of "cd",
- if GDB dumps core in these testcases, the GDB core dump will still end
- up in build/gdb/testsuite/, and can thus be detected as an unexpected
- core.

- gdb: make use of RAII in run_inferior_call

-
- Of the three locals that I've changed, the only one that I believe is

- Use PyBool_FromLong
- I noticed a few spots that were explicitly creating new references to

- aarch64: Allow PC-relative relocations against protected STT_FUNC for -shared
- __attribute__((visibility("protected"))) void *foo() {
- return (void *)foo;
- }
-
- gcc -fpic -shared -fuse-ld=bfd fails with the confusing diagnostic:
-
- relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `foo' which may bind externally can not be used when making a shared object; recompile with -fPIC
-
- Call _bfd_elf_symbol_refs_local_p with local_protected==true to suppress
- the error. The new behavior matches gold and ld.lld.
-
- Note: if some code tries to use direct access relocations to take the
- address of foo (likely due to -fno-pic), the pointer equality will
- break, but the error should be reported on the executable link, not on
- the innocent shared object link. glibc 2.36 will give a warning at
- relocation resolving time.

- aarch64: Disallow copy relocations on protected data
- If an executable has copy relocations for extern protected data, that
- can only work if the shared object containing the definition is built
- with assumptions (a) the compiler emits GOT-generating relocations (b)
- the linker produces R_*_GLOB_DAT instead of R_*_RELATIVE. Otherwise the
- shared object uses its own definition directly and the executable
- accesses a stale copy. Note: the GOT relocations defeat the purpose of
- protected visibility as an optimization, and it turns out this never
- worked perfectly.
-
- glibc 2.36 will warn on copy relocations on protected data. Let's
- produce a warning at link time, matching ld.lld which has been used on
- many aarch64 OSes.
-
- Note: x86 requires GNU_PROPERTY_NO_COPY_ON_PROTECTED to have the error.
- This is to largely due to GCC 5's "x86-64: Optimize access to globals in
- PIE with copy reloc" which started to use direct access relocations for
- external data symbols in -fpie mode.
-
- GCC's aarch64 port does not have the change. Nowadays with most builds
- switching to -fpie/-fpic, aarch64 mostly doesn't need to worry about
- copy relocations. So for aarch64 we simply don't check
- GNU_PROPERTY_NO_COPY_ON_PROTECTED.

- libctf: fix linking together multiple objects derived from the same source
- Right now, if you compile the same .c input repeatedly with CTF enabled
- and different compilation flags, then arrange to link all of these
- together, then things misbehave in various ways. libctf may conflate
- either inputs (if the .o files have the same name, say if they are
- stored in different .a archives), or per-CU outputs when conflicting
- types are found: the latter can lead to entirely spurious errors when
- it tries to produce multiple per-CU outputs with the same name
- (discarding all but the last, but then looking for types in the earlier
- ones which have just been thrown away).
-
- Fixing this is multi-pronged. Both inputs and outputs need to be
- differentiated in the hashtables libctf keeps them in: inputs with the
- same cuname and filename need to be considered distinct as long as they
- have different associated CTF dicts, and per-CU outputs need to be
- considered distinct as long as they have different associated input
- dicts. Right now there is nothing tying the two together other than the
- CU name: fix this by introducing a new field in the ctf_dict_t named
- ctf_link_in_out, which (for input dicts) points to the associated per-CU
- output dict (if any), and for output dicts points to the associated
- input dict. At creation time the name used is completely arbitrary:
- it's only important that it be distinct if CTF dicts are distinct. So,
- when a clash is found, adjust the CU name by sticking the number of
- elements in the input on the end. At output time, the CU name will
- appear in the linked object, so it matters a little more that it look
- slightly less ugly: in conflicting cases, append an incrementing
- integer, starting at 0.
-
- This naming scheme is not very helpful, but it's hard to see what else
- we can do. The input .o name may be the same. The input .a name is not
- even visible to ctf_link, and even *that* might be the same, because
- .a's can contain many members with the same name, all of which
- participate in the link. All we really know is that the two have
- distinct dictionaries with distinct types in them, and at least this way
- they are all represented, any any symbols, variables etc referring to
- those types are accurately stored.
-
- (As a side-effect this also fixes a use-after-free and double-free when
- errors are found during variable or symbol emission.)
-
- Use the opportunity to prevent a couple of sources of problems, to wit
- changing the active CU mappings when a link has already been done
- (no effect on ld, which doesn't use CU mappings at all), and causing
- multiple consecutive ctf_link's to have the same net effect as just
- doing the last one (no effect on ld, which only ever does one
- ctf_link) rather than having the links be a sort of half-incremental
- not-really-intended mess.

- PR29256, memory leak in obj_elf_section_name
- When handling section names in quotes obj_elf_section_name calls
- demand_copy_C_string, which puts the name on the gas notes obstack.
- Such strings aren't usually freed, since obstack_free frees all more
- recently allocated objects as well as its arg. When handling
- non-quoted names, obj_elf_section_name mallocs the name. Due to the
- mix of allocation strategies it isn't possible for callers to free
- names, if that was desirable. Partially fix this by always creating
- names on the obstack, which is more efficient anyway. (You still
- can't obstack_free on error paths due to the xtensa
- tc_canonicalize_section_name.) Also remove a couple of cases where
- the name is dup'd for no good reason as far as I know.

- Fix GDB build with GCC 4.8 & 4.9
- With gcc 4.8/4.9, we run into this build failure (and other similar
- ones):
-
- /home/palves/gdb/binutils-gdb/src/gdb/location.h:224:59: error: could not convert ‘{0, LINE_OFFSET_UNKNOWN}’ from ‘<brace-enclosed initializer list>’ to ‘line_offset’
- struct line_offset line_offset = {0, LINE_OFFSET_UNKNOWN};
- ^
-
- The issue is that at around the GCC 4.8/4.9 era, a default member
- initializer prevented the struct from being an aggregate, so you
- cannot use aggregate initialization on them. That rule changed after
- GCC 4.9 and GCC 5 & later uses new rules.
-
- Fix this by not using aggregate initialization for struct line_offset.
- The default member initization already leaves line_offset as {0,
- LINE_OFFSET_UNKNOWN}, so initialization to those values can just go
- away. The remaining cases are of the form {0, LINE_OFFSET_NONE}, and
- those cases can be better rewritten to delay setting the sign field
- until we know we have a valid offset.

-
- Eliminate the two-level data structures behind location_specs
- Currently, there's the location_spec hierarchy, and then some
- location_spec subclasses have their own struct type holding all their
- data fields.
-
- I.e., there is this:
-
- location_spec
- explicit_location_spec
- linespec_location_spec
- address_location_spec
- probe_location_spec
-
- and then these separate types:
-
- explicit_location
- linespec_location
-
- where:
-
- explicit_location_spec
- has-a explicit_location
- linespec_location_spec
- has-a linespec_location
-
- This patch eliminates explicit_location and linespec_location,
- inlining their members in the corresponding location_spec type.
-
- The location_spec subclasses were the ones currently defined in
- location.c, so they are moved to the header. Since the definitions of
- the classes are now visible, we no longer need location_spec_deleter.
-
- Some constructors that are used for cloning location_specs, like:
-
- explicit explicit_location_spec (const struct explicit_location *loc)
-
- ... were converted to proper copy ctors.
-
- In the process, initialize_explicit_location is eliminated, and some
- functions that returned the "data type behind a locspec", like
- get_linespec_location are converted to downcast functions, like
- as_linespec_location_spec.

-
- event_location -> location_spec
- Currently, GDB internally uses the term "location" for both the
- location specification the user input (linespec, explicit location, or
- an address location), and for actual resolved locations, like the
- breakpoint locations, or the result of decoding a location spec to
- SaLs. This is expecially confusing in the breakpoints module, as
- struct breakpoint has these two fields:
-
- breakpoint::location;
- breakpoint::loc;
-
- "location" is the location spec, and "loc" is the resolved locations.
-
- And then, we have a method called "locations()", which returns the
- resolved locations as range...
-
- The location spec type is presently called event_location:
-
- /* Location we used to set the breakpoint. */
- event_location_up location;
-
- and it is described like this:
-
- /* The base class for all an event locations used to set a stop event
- in the inferior. */
-
- struct event_location
- {
-
- and even that is incorrect... Location specs are used for finding
- actual locations in the program in scenarios that have nothing to do
- with stop events. E.g., "list" works with location specs.
-
- To clean all this confusion up, this patch renames "event_location" to
- "location_spec" throughout, and then all the variables that hold a
- location spec, they are renamed to include "spec" in their name, like
- e.g., "location" -> "locspec". Similarly, functions that work with
- location specs, and currently have just "location" in their name are
- renamed to include "spec" in their name too.

- gdb/arm: Make sp alias for one of the other stack pointers

- gdb/arm: Track msp and psp
- For Arm Cortex-M33 with security extensions, there are 4 different
- stack pointers (msp_s, msp_ns, psp_s, psp_ns). To be compatible
- with earlier Cortex-M derivates, the msp and psp registers are
- aliases for one of the 4 real stack pointer registers.
-
- These are the combinations that exist:
- sp -> msp -> msp_s
- sp -> msp -> msp_ns
- sp -> psp -> psp_s
- sp -> psp -> psp_ns
-
- This means that when the GDB client is to show the value of "msp",
- the value should always be equal to either "msp_s" or "msp_ns".
- Same goes for "psp".
-
- To add a bit more context; GDB does not really use the register msp
- (or psp) internally, but they are part of the set of registers which
- are provided by the target.xml file. As a result, they will be part
- of the set of registers printed by the "info r" command.
-
- Without this particular patch, GDB will hit the assert in the bottom
- of arm_cache_get_sp_register function.

- gdb: unify two dis_asm_read_memory functions in disasm.c
- After the recent restructuring of the disassembler code, GDB has ended
- up with two identical class static functions, both called
- dis_asm_read_memory, with identical implementations.
-
- My first thought was to move these out of their respective classes,
- and just make them global functions, then I'd only need a single
- copy.
-
- And maybe that's the right way to go. But I disliked that by doing
- that I loose the encapsulation of the method with the corresponding
- disassembler class.
-
- So, instead, I placed the static method into its own class, and had
- both the gdb_non_printing_memory_disassembler and gdb_disassembler
- classes inherit from this new class as an additional base-class.
-
- In terms of code generated, I don't think there's any significant
- difference with this approach, but I think this better reflects how
- the function is closely tied to the disassembler.
-
- There should be no user visible changes after this commit.

- gdb: refactor the non-printing disassemblers
- This commit started from an observation I made while working on some
- other disassembler patches, that is, that the function
- gdb_buffered_insn_length, is broken ... sort of.
-
- I noticed that the gdb_buffered_insn_length function doesn't set up
- the application data field if the disassemble_info structure.
-
- Further, I noticed that some architectures, for example, ARM, require
- that the application_data field be set, see gdb_print_insn_arm in
- arm-tdep.c.
-
- And so, if we ever use gdb_buffered_insn_length for ARM, then GDB will
- likely crash. Which is why I said only "sort of" broken. Right now
- we don't use gdb_buffered_insn_length with ARM, so maybe it isn't
- broken yet?
-
- Anyway to prove to myself that there was a problem here I extended the
- disassembler self tests in disasm-selftests.c to include a test of
- gdb_buffered_insn_length. As I run the test for all architectures, I
- do indeed see GDB crash for ARM.
-
- To fix this we need gdb_buffered_insn_length to create a disassembler
- that inherits from gdb_disassemble_info, but we also need this new
- disassembler to not print anything.
-
- And so, I introduce a new gdb_non_printing_disassembler class, this is
- a disassembler that doesn't print anything to the output stream.
-
- I then observed that both ARC and S12Z also create non-printing
- disassemblers, but these are slightly different. While the
- disassembler in gdb_non_printing_disassembler reads the instruction
- from a buffer, the ARC and S12Z disassemblers read from target memory
- using target_read_code.
-
- And so, I further split gdb_non_printing_disassembler into two
- sub-classes, gdb_non_printing_memory_disassembler and
- gdb_non_printing_buffer_disassembler.
-
- The new selftests now pass, but otherwise, there should be no user
- visible changes after this commit.

-
- gdb/python: implement the print_insn extension language hook
- This commit extends the Python API to include disassembler support.
-
- The motivation for this commit was to provide an API by which the user
- could write Python scripts that would augment the output of the
- disassembler.
-
- To achieve this I have followed the model of the existing libopcodes
- disassembler, that is, instructions are disassembled one by one. This
- does restrict the type of things that it is possible to do from a
- Python script, i.e. all additional output has to fit on a single line,
- but this was all I needed, and creating something more complex would,
- I think, require greater changes to how GDB's internal disassembler
- operates.
-
- The disassembler API is contained in the new gdb.disassembler module,
- which defines the following classes:
-
- DisassembleInfo
-
- Similar to libopcodes disassemble_info structure, has read-only
- properties: address, architecture, and progspace. And has methods:
- __init__, read_memory, and is_valid.
-
- Each time GDB wants an instruction disassembled, an instance of
- this class is passed to a user written disassembler function, by
- reading the properties, and calling the methods (and other support
- methods in the gdb.disassembler module) the user can perform and
- return the disassembly.
-
- Disassembler
-
- This is a base-class which user written disassemblers should
- inherit from. This base class provides base implementations of
- __init__ and __call__ which the user written disassembler should
- override.
-
- DisassemblerResult
-
- This class can be used to hold the result of a call to the
- disassembler, it's really just a wrapper around a string (the text
- of the disassembled instruction) and a length (in bytes). The user
- can return an instance of this class from Disassembler.__call__ to
- represent the newly disassembled instruction.
-
- The gdb.disassembler module also provides the following functions:
-
- register_disassembler
-
- This function registers an instance of a Disassembler sub-class
- as a disassembler, either for one specific architecture, or, as a
- global disassembler for all architectures.
-
- builtin_disassemble
-
- This provides access to GDB's builtin disassembler. A common
- use case that I see is augmenting the existing disassembler output.
- The user code can call this function to have GDB disassemble the
- instruction in the normal way. The user gets back a
- DisassemblerResult object, which they can then read in order to
- augment the disassembler output in any way they wish.
-
- This function also provides a mechanism to intercept the
- disassemblers reads of memory, thus the user can adjust what GDB
- sees when it is disassembling.
-
- The included documentation provides a more detailed description of the
- API.
-
- There is also a new CLI command added:
-
- maint info python-disassemblers
-
- This command is defined in the Python gdb.disassemblers module, and
- can be used to list the currently registered Python disassemblers.

-
- gdb: add extension language print_insn hook
- This commit is setup for the next commit.
-
- In the next commit I will add a Python API to intercept the print_insn
- calls within GDB, each print_insn call is responsible for
- disassembling, and printing one instruction. After the next commit it
- will be possible for a user to write Python code that either wraps
- around the existing disassembler, or even, in extreme situations,
- entirely replaces the existing disassembler.
-
- This commit does not add any new Python API.
-
- What this commit does is put the extension language framework in place
- for a print_insn hook. There's a new callback added to 'struct
- extension_language_ops', which is then filled in with nullptr for Python
- and Guile.
-
- Finally, in the disassembler, the code is restructured so that the new
- extension language function ext_lang_print_insn is called before we
- delegate to gdbarch_print_insn.
-
- After this, the next commit can focus entirely on providing a Python
- implementation of the new print_insn callback.
-
- There should be no user visible change after this commit.

-
- gdb: add new base class to gdb_disassembler
- The motivation for this change is an upcoming Python disassembler API
- that I would like to add. As part of that change I need to create a
- new disassembler like class that contains a disassemble_info and a
- gdbarch. The management of these two objects is identical to how we
- manage these objects within gdb_disassembler, so it might be tempting
- for my new class to inherit from gdb_disassembler.
-
- The problem however, is that gdb_disassembler has a tight connection
- between its constructor, and its print_insn method. In the
- constructor the ui_file* that is passed in is replaced with a member
- variable string_file*, and then in print_insn, the contents of the
- member variable string_file are printed to the original ui_file*.
-
- What this means is that the gdb_disassembler class has a tight
- coupling between its constructor and print_insn; the class just isn't
- intended to be used in a situation where print_insn is not going to be
- called, which is how my (upcoming) sub-class would need to operate.
-
- My solution then, is to separate out the management of the
- disassemble_info and gdbarch into a new gdb_disassemble_info class,
- and make this class a parent of gdb_disassembler.
-
- In arm-tdep.c and mips-tdep.c, where we used to cast the
- disassemble_info->application_data to a gdb_disassembler, we can now
- cast to a gdb_disassemble_info as we only need to access the gdbarch
- information.
-
- Now, my new Python disassembler sub-class will still want to print
- things to an output stream, and so we will want access to the
- dis_asm_fprintf functionality for printing.
-
- However, rather than move this printing code into the
- gdb_disassemble_info base class, I have added yet another level of
- hierarchy, a gdb_printing_disassembler, thus the class structure is
- now:
-
- struct gdb_disassemble_info {};
- struct gdb_printing_disassembler : public gdb_disassemble_info {};
- struct gdb_disassembler : public gdb_printing_disassembler {};
-
- In a later commit my new Python disassembler will inherit from
- gdb_printing_disassembler.
-
- The reason for adding the additional layer to the class hierarchy is
- that in yet another commit I intend to rewrite the function
- gdb_buffered_insn_length, and to do this I will be creating yet more
- disassembler like classes, however, these will not print anything,
- thus I will add a gdb_non_printing_disassembler class that also
- inherits from gdb_disassemble_info. Knowing that that change is
- coming, I've gone with the above class hierarchy now.
-
- There should be no user visible changes after this commit.

- Implement lazy FPU initialization for ravenscar
- Some ravenscar runtimes implement lazy FPU handling. On these
- runtimes, the FPU is only initialized when a task tries to use it.
- Furthermore, the FP registers aren't automatically saved on a task
- switch -- instead, the save is deferred until the new task tries to
- use the FPU. Furthermore, each task's context area has a flag
- indicating whether the FPU has been initialized for this task.
-
- This patch teaches GDB to understand this implementation. When
- fetching or storing registers, GDB now checks to see whether the live
- FP registers should be used. If not, the task's saved FP registers
- will be used if the task has caused FPU initialization.
-
- Currently only AArch64 uses this code. bb-runtimes implements this
- for ARM as well, but GDB doesn't yet have an arm-ravenscar-thread.c.

-
- Reimplement ravenscar registers using tables
- Currently, the ravenscar-thread implementation for each architecture
- is written by hand. However, these are actually written by
- copy-paste. It seems better to switch to a table-driven approach.

- The previous code also fetched all registers whenever any register was
- requested. This is corrected in the new implementation.

- Fix bugs in aarch64-ravenscar-thread.c
- We found a few bugs in aarch64-ravenscar-thread.c.
-
- First, some of the register offsets were incorrect. The "bb-runtimes"
- file for this runtime had the wrong offsets in comments, which GDB
- took to be correct. However, those comments didn't account for
- alignment. This patch adjusts the offsets.
-
- Next, the "FPU Saved field" is not a register -- it is an
- implementation detail of the runtime. This is removed.
-
- Finally, I think the FP registers are actually named V0-V31, and the
- "Q" names are pseudo-registers. This patch fixes the comment.

- Debug support for global alias variable
- Starting with (future) Clang 15 (since
- https://reviews.llvm.org/D120989), Clang emits the DWARF information
- of global alias variables as DW_TAG_imported_declaration. However,
- GDB does not handle it. It incorrectly always reads this tag as
- C++/Fortran imported declaration (type alias, namespace alias and
- Fortran module). This commit adds support to handle this tag as an
- alias variable.

- This change fixes the failures in the gdb.base/symbol-alias.exp

- BFD_RELOC_MIPS_16
- MIPS should not be using BFD_RELOC_16 for its R_MIPS_16 relocation,
- since R_MIPS_16 specifies a 16-bit field in a 32-bit word.
- BFD_RELOC_16, emitted by generic code to handle fixups on 16-bit data
- directives, expects fixups to operate on the whole of a 16-bit word.
-
- This patch corrects the problem by using BFD_RELOC_MIPS_16, a new bfd
- reloc that is used to generate R_MIPS_16. BFD_RELOC_16 is handled in
- md_apply_fix for cases where the fixup can be applied at assembly
- time. Like BFD_RELOC_8, BFD_RELOC_16 now has no corresponding object
- file relocation, and thus .half, .hword, .short and .dc.w must be
- resolved at assembly time. BFD_RELOC_MIPS_REL16 is removed by this
- patch since it isn't used.

-2022-06-13 Jan Beulich <jbeulich@suse.com>
-
- x86: replace global scratch buffer
- With its movement to the stack, and with the subsequent desire to
- initialize the entire instr_info instances, this has become doubly
- inefficient. Individual users have better knowledge of how big a buffer
- they need, and in a number of cases going through an intermediate buffer
- can be avoided altogether.
-
- Having got confirmation that it wasn't intentional to print memory
- operand displacements with inconsistent style, print_displacement() is
- now using dis_style_address_offset consistently (eliminating the need
- for callers to pass in a style).
-
- While touching print_operand_value() also convert its "hex" parameter to
- bool. And while altering (and moving) oappend_immediate(), fold
- oappend_maybe_intel_with_style() into its only remaining caller. Finally
- where doing adjustments, use snprintf() in favor of sprintf().

- x86: shrink prefix related disassembler state fields
- By changing the values used for "artificial" prefix values,
- all_prefixes[] can be shrunk to array of unsigned char. All that
- additionally needs adjusting is the printing of possible apparently
- standalone prefixes when recovering from longjmp(): Simply check
- whether any prefixes were successfully decoded, to avoid converting
- opcode bytes matching the "artificial" values to prefix mnemonics.
-
- Similarly by re-arranging the bits assigned to PREFIX_* mask values
- we can fit all segment register masks in a byte and hence shrink
- active_seg_prefix to unsigned char.
-
- Somewhat similarly with last_*_prefix representing offsets into the
- opcode being disassembled, signed char is sufficient to hold all possible
- values.

- x86: properly initialize struct instr_info instance(s)
- Commit 39fb369834a3 ("opcodes: Make i386-dis.c thread-safe") introduced
- a lot of uninitialized data. Alan has in particular observed ubsan
- taking issue with the loop inverting the order of operands, where
- op_riprel[] - an array of bool - can hold values other than 0 or 1.
-
- Move instantiation of struct instr_info into print_insn() (thus having
- just a single central point), and make use of C99 dedicated initializers
- to fill fields right in the initializer where possible. This way all
- fields not explicitly initialized will be zero-filled, which in turn
- allows dropping of some other explicit initialization later in the
- function or in ckprefix(). Additionally this removes a lot of
- indirection, as all "ins->info" uses can simply become "info".
-
- Make one further arrangement though, to limit the amount of data needing
- (zero)initializing on every invocation: Convert the op_out structure
- member to just an array of pointers, with the actual arrays living
- inside print_insn() (and, as befoe, having just their 1st char filled
- with nul).
-
- While there, instead of adjusting print_insn()'s forward declaration,
- arrange for no such declaration to be needed in the first place.

- Fix self-test failure in addrmap
- Mark pointed out that my recent addrmap C++-ficiation changes caused a
- regression in the self-tests. This patch fixes the problem by
- updating this test not to allocate the mutable addrmap on an obstack.
-
- Remove psymtab_addrmap
- While working on addrmaps, I noticed that psymtab_addrmap is no longer
- needed now. It was introduced in ancient times as an optimization for
- DWARF, but no other symbol reader was ever updated to use it. Now
- that DWARF does not use psymtabs, it can be deleted.
-
- Use malloc for mutable addrmaps
- Mutable addrmaps currently require an obstack. This was probably done
- to avoid having to call splay_tree_delete, but examination of the code
- shows that all mutable obstacks have a limited lifetime -- now it's
- simple to treat them as ordinary C++ objects, in some cases
- stack-allocating them, and have a destructor to make the needed call.
- This patch implements this change.
-
- Remove addrmap::create_fixed
- addrmap::create_fixed is just a simple wrapper for 'new', so remove it
- in favor of uses of 'new'.
-
- Remove addrmap_create_mutable
- This removes addrmap_create_mutable in favor of using 'new' at the
- spots where the addrmap is created.
-
- Remove addrmap wrapper functions
- This removes the various addrmap wrapper functions in favor of simple
- method calls on the objects themselves.
-
- Move addrmap classes to addrmap.h
- This moves the addrmap class definitions to addrmap.h. This is safe
- to do now that the contents are private.
-
- Privacy for addrmap_mutable
- This changes addrmap_mutable so that its data members are private.
-
- Privacy for addrmap_fixed
- This changes addrmap_fixed so that its data members are private.
- It also makes struct addrmap_transition private as well.
-
- Use inheritance for addrmap
- This is a simply C++-ification of the basics of addrmap: it uses
- virtual methods rather than a table of function pointers, and it
- changes the concrete implementations to be subclasses.

- if (tmpulongest == tdep->ioctl_FIOCLEX
- || tmpulongest == tdep->ioctl_FIONCLEX

-
- The PowerPC ioctl value for ioctl_TCSETW is 0x802c7415. The variable
- ioctl_TCSETW is defined in gdb/linux-record.h as an int. The TCSETW value
- has the MSB set to one so it is a negative integer. The comparison of the

-
- This patch changes the declarations for the ioctl_* values in struct

-
- gdb/testsuite: remove definition of true/false from gdb_compiler_info
- Since pretty much forever the get_compiler_info function has included
- these lines:
-
- # Most compilers will evaluate comparisons and other boolean
- # operations to 0 or 1.
- uplevel \#0 { set true 1 }
- uplevel \#0 { set false 0 }
-
- These define global variables true (to 1) and false (to 0).
-
- It seems odd to me that these globals are defined in
- get_compiler_info, I guess maybe the original thinking was that if a
- compiler had different true/false values then we would detect it there
- and define true/false differently.
-
- I don't think we should be bundling this logic into get_compiler_info,
- it seems weird to me that in order to use $true/$false a user needs to
- first call get_compiler_info.
-
- It would be better I think if each test script that wants these
- variables just defined them itself, if in the future we did need
- different true/false values based on compiler version then we'd just
- do:
-
- if { [test_compiler_info "some_pattern"] } {
- # Defined true/false one way...
- } else {
- # Defined true/false another way...
- }
-
- But given the current true/false definitions have been in place since
- at least 1999, I suspect this will not be needed any time soon.
-
- Given that the definitions of true/false are so simple, right now my
- suggestion is just to define them in each test script that wants
- them (there's not that many). If we ever did need more complex logic
- then we can always add a function in gdb.exp that sets up these
- globals, but that seems overkill for now.
-
- There should be no change in what is tested after this commit.

- gdb/aarch64: fix 32-bit arm compatibility
- GDB's ability to run 32-bit ARM processes on an AArch64 native target
- is currently broken. The test gdb.multi/multi-arch.exp currently
- fails with a timeout.
-
- The cause of these problems is the following three functions:
-
- aarch64_linux_nat_target::thread_architecture
- aarch64_linux_nat_target::fetch_registers
- aarch64_linux_nat_target::store_registers
-
- What has happened, over time, is that these functions have been
- modified, forgetting that any particular thread (running on the native
- target) might be an ARM thread, or might be an AArch64 thread.
-
- The problems always start with a line similar to this:
-
- aarch64_gdbarch_tdep *tdep
- = (aarch64_gdbarch_tdep *) gdbarch_tdep (inf->gdbarch);
-
- The problem with this line is that if 'inf->gdbarch' is an ARM
- architecture, then gdbarch_tdep will return a pointer to an
- arm_gdbarch_tdep object, not an aarch64_gdbarch_tdep object. The
- result of the above cast will, as a consequence, be undefined.
-
- In aarch64_linux_nat_target::thread_architecture, after the undefined
- cast we then proceed to make use of TDEP, like this:
-
- if (vq == tdep->vq)
- return inf->gdbarch;
-
- Obviously at this point the result is undefined, but, if this check
- returns false we then proceed with this code:
-
- struct gdbarch_info info;
- info.bfd_arch_info = bfd_lookup_arch (bfd_arch_aarch64, bfd_mach_aarch64);
- info.id = (int *) (vq == 0 ? -1 : vq);
- return gdbarch_find_by_info (info);
-
- As a consequence we will return an AArch64 gdbarch object for our ARM
- thread! Things go downhill from there on.
-
- There are similar problems, with similar undefined behaviour, in the
- fetch_registers and store_registers functions.
-
- The solution is to make use of a check like this:
-
- if (gdbarch_bfd_arch_info (inf->gdbarch)->bits_per_word == 32)
-
- If the word size is 32 then we know we have an ARM architecture. We
- just need to make sure that we perform this check before trying to
- read the tdep field.
-
- In aarch64_linux_nat_target::thread_architecture a little reordering,
- and the addition of the above check allows us to easily avoid the
- undefined behaviour.
-
- For fetch_registers and store_registers I made the decision to split
- each of the functions into two new helper functions, and so
- aarch64_linux_nat_target::fetch_registers now calls to either
- aarch64_fetch_registers or aarch32_fetch_registers, and there's a
- similar change for store_registers.
-
- One thing I had to decide was whether to place the new aarch32_*
- functions into the aarch32-linux-nat.c file. In the end I decided to
- NOT place the functions there, but instead leave them in
- aarch64-linux-nat.c, my reasoning was this:
-
- The existing functions in that file are shared from arm-linux-nat.c
- and aarch64-linux-nat.c, this generic code to support 32-bit ARM
- debugging from either native target.
-
- In contrast, the two new aarch32 functions I have added _only_ make
- sense when debugging on an AArch64 native target. These function
- shouldn't be called from arm-linux-nat.c at all, and so, if we places
- the functions into aarch32-linux-nat.c, the functions would be built
- into a 32-bit ARM GDB, but never used.
-
- With that said, there's no technical reason why they couldn't go in
- aarch32-linux-nat.c, so if that is preferred I'm happy to move them.
-
- After this commit the gdb.multi/multi-arch.exp passes.

- gdb/testsuite: solve problems with compiler_info caching
- After this commit:
-
- commit 44d469c5f85a4243462b8966722dafa62b602bf5
- Date: Tue May 31 16:43:44 2022 +0200
-
- gdb/testsuite: add Fortran compiler identification to GDB
-
- Some regressions were noticed:
-
- https://sourceware.org/pipermail/gdb-patches/2022-May/189673.html
-
- The problem is associated with how compiler_info variable is cached
- between calls to get_compiler_info.
-
- Even before the above commit, get_compiler_info supported two
- language, C and C++. Calling get_compiler_info would set the global
- compiler_info based on the language passed as an argument to
- get_compiler_info, and, in theory, compiler_info would not be updated
- for the rest of the dejagnu run.
-
- This obviously is slightly broken behaviour. If the first call to
- get_compiler_info was for the C++ language then compiler_info would be
- set based on the C++ compiler in use, while if the first call to
- get_compiler_info was for the C language then compiler_info would be
- set based on the C compiler.
-
- This probably wasn't very noticable, assuming a GCC based test
- environment then in most cases the C and C++ compiler would be the
- same version.
-
- However, if the user starting playing with CC_FOR_TARGET or
- CXX_FOR_TARGET, then they might not get the behaviour they expect.
-
- Except, to make matters worse, most of the time, the user probably
- would get the behaviour they expected .... except when they didn't!
- I'll explain:
-
- In gdb.exp we try to avoid global variables leaking between test
- scripts, this is done with the help of the two procs
- gdb_setup_known_globals and gdb_cleanup_globals. All known globals
- are recorded before a test script starts, and then, when the test
- script ends, any new globals are deleted.
-
- Normally, compiler_info is only set as a result of a test script
- calling get_compiler_info or test_compiler_info. This means that the
- compiler_info global will not exist when the test script starts, but
- will exist when the test script end, and so, the compiler_info
- variable is deleted at the end of each test.
-
- This means that, in reality, the compiler_info is recalculated once
- for each test script, hence, if a test script just checks on the C
- compiler, or just checks on the C++ compiler, then compiler_info will
- be correct and the user will get the behaviour they expect.
-
- However, if a single test script tries to check both the C and C++
- compiler versions then this will not work (even before the above
- commit).
-
- The situation is made worse be the behaviour or the load_lib proc.
- This proc (provided by dejagnu) will only load each library once.
- This means that if a library defines a global, then this global would
- normally be deleted at the end of the first test script that includes
- the library.
-
- As future attempts to load the library will not actually reload it,
- then the global will not be redefined and would be missing for later
- test scripts that also tried to load that library.
-
- To work around this issue we override load_lib in gdb.exp, this new
- version adds all globals from the newly loaded library to the list of
- globals that should be preserved (not deleted).
-
- And this is where things get interesting for us. The library
- trace-support.exp includes calls, at the file scope, to things like
- is_amd64_regs_target, which cause get_compiler_info to be called.
- This means that after loading the library the compiler_info global is
- defined.
-
- Our override of load_lib then decides that this new global has to be
- preserved, and adds it to the gdb_persistent_globals array.
-
- From that point on compiler_info will never be recomputed!
-
- This commit addresses all the caching problems by doing the following:
-
- Change the compiler_info global into compiler_info_cache global. This
- new global is an array, the keys of this array will be each of the
- supported languages, and the values will be the compiler version for
- that language.
-
- Now, when we call get_compiler_info, if the compiler information for
- the specific language has not been computed, then we do that, and add
- it to the cache.
-
- Next, compiler_info_cache is defined by calling
- gdb_persistent_global. This automatically adds the global to the list
- of persistent globals. Now the cache will not be deleted at the end
- of each test script.
-
- This means that, for a single test run, we will compute the compiler
- version just once for each language, this result will then be cached
- between test scripts.
-
- Finally, the legacy 'gcc_compiled' flag is now only set when we call
- get_compiler_info with the language 'c'. Without making this change
- the value of 'gcc_compiled' would change each time a new language is
- passed to get_compiler_info. If the last language was e.g. Fortran,
- then gcc_compiled might be left false.

-
- gdb/testsuite: handle errors better in test_compiler_info
- Now that get_compiler_info might actually fail (if the language is not
- handled), then we should try to handle this failure better in
- test_compiler_info.
-
- After this commit, if get_compiler_info fails then we will return a
- suitable result depending on how the user called test_compiler_info.
-
- If the user does something like:
-
- set version [test_compiler_info "" "unknown-language"]
-
- Then test_compiler_info will return an empty string. My assumption is
- that the user will be trying to match 'version' against something, and
- the empty string hopefully will not match.
-
- If the user does something like:
-
- if { [test_compiler_info "some_pattern" "unknown-language"] } {
- ....
- }
-
- Then test_compiler_info will return false which seems the obvious
- choice.
-
- There should be no change in the test results after this commit.

-
- gdb/testsuite: make 'c' default language for get/test compiler info
- This commit is a minor cleanup for the two functions (in gdb.exp)
- get_compiler_info and test_compiler_info.
-
- Instead of using the empty string as the default language, and just
- "knowing" that this means the C language. Make this explicit. The
- language argument now defaults to "c" if not specified, and the if
- chain in get_compiler_info that checks the language not explicitly
- handles "c" and gives an error for unknown languages.
-
- This is a good thing, now that the API appears to take a language, if
- somebody does:
-
- test_compiler_info "xxxx" "rust"
-
- to check the version of the rust compiler then we will now give an
- error rather than just using the C compiler and leaving the user
- having to figure out why they are not getting the results they
- expect.
-
- After a little grepping, I think the only place we were explicitly
- passing the empty string to either get_compiler_info or
- test_compiler_info was in gdb_compile_shlib_1, this is now changed to
- pass "c" as the default language.

- The procedure gcc_major_version was earlier using the global variable
- compiler_info to retrieve gcc's major version. This is discouraged and
- (as can be read in a comment in compiler.c) compiler_info should be
- local to get_compiler_info and test_compiler_info.
-
- The preferred way of getting the compiler string is via calling
- test_compiler_info without arguments. Gcc_major_version was changed to
- do that.

- gdb/testsuite: resolve duplicate test names in gdb.threads/tls.exp
- While running the gdb.threads/tls.exp test with a GDB configured
- without Python, I noticed some duplicate test names.
-
- This is caused by a call to skip_python_tests that is within a proc
- that is called multiple times by the test script. Each call to
- skip_python_tests results in a call to 'unsupported', and this causes
- the duplicate test names.
-
- After this commit we now call skip_python_tests just once and place
- the result into a variable. Now, instead of calling skip_python_tests
- multiple times, we just check the variable.
-
- There should be no change in what is tested after this commit.

- The throw_perror_with_name function is not used outside of utils.c
- right now. And as perror_with_name is just a wrapper around

- perror_with_name.

- gdb: remove trailing '.' from perror_with_name calls
- I ran into this error while working on AArch64 GDB:
-
- Unable to fetch VFP registers.: Invalid argument.
-
- Notice the '.:' in the middle of this error message.
-
- This is because of this call in aarch64-linux-nat.c:
-
- perror_with_name (_("Unable to fetch VFP registers."));
-
- The perror_with_name function take a string, and adds ': <message>' to
- the end the string, so I don't think the string that we pass to
- perror_with_name should end in '.'.
-
- This commit removes all of the trailing '.' characters from
- perror_with_name calls, which give more readable error messages.
-
- I don't believe that any of these errors are tested in the
- testsuite (after a little grepping).

- Move CU queue to dwarf2_per_objfile

- libopcodes: extend the styling within the i386 disassembler
- The i386 disassembler is pretty complex. Most disassembly is done
- indirectly; operands are built into buffers within a struct instr_info
- instance, before finally being printed later in the disassembly
- process.
-
- Sometimes the operand buffers are built in a different order to the
- order in which they will eventually be printed.
-
- Each operand can contain multiple components, e.g. multiple registers,
- immediates, other textual elements (commas, brackets, etc).
-
- When looking for how to apply styling I guess the ideal solution would
- be to move away from the operands being a single string that is built
- up, and instead have each operand be a list of "parts", where each
- part is some text and a style. Then, when we eventually print the
- operand we would loop over the parts and print each part with the
- correct style.
-
- But it feels like a huge amount of work to move from where we are
- now to that potentially ideal solution. Plus, the above solution
- would be pretty complex.
-
- So, instead I propose a .... different solution here, one that works
- with the existing infrastructure.
-
- As each operand is built up, piece be piece, we pass through style
- information. This style information is then encoded into the operand
- buffer (see below for details). After this the code can continue to
- operate as it does right now in order to manage the set of operand
- buffers.
-
- Then, as each operand is printed we can split the operand buffer into
- chunks at the style marker boundaries, with each chunk being printed
- with the correct style.
-
- For encoding the style information I use a single character, currently
- \002, followed by the style encoded as a single hex digit, followed
- again by the \002 character.
-
- This of course relies on there not being more than 16 styles, but that
- is currently true, and hopefully will remain true for the foreseeable
- future.
-
- The other major concern that has arisen around this work is whether
- the escape character could ever be encountered in output naturally
- generated by the disassembler. If this did happen then the escape
- characters would be stripped from the output, and the wrong styling
- would be applied.
-
- However, I don't believe that this is currently a problem.
- Disassembler content comes from a number of sources. First there's
- content that copied directly from the i386-dis.c file, this is things
- like register names, and other syntax elements (brackets, commas,
- etc). We can easily check that the i386-dis.c file doesn't contain
- our special character.
-
- The next source of content are immediate operands. The text for these
- operands is generated by calls into libc. By selecting a
- non-printable character we can be confident that this is not something
- that libc will generate as part of an immediate representation.
-
- The other output that appears to be from the disassembler is operands
- that contain addresses and (possibly) symbol names. It is quite
- possible that a symbol name might contain any special character we
- could imagine, so is this a problem?
-
- I don't think it is, we don't actually print address and symbol
- operands through the disassembler, instead, the disassembler calls
- back to the user (objdump, gdb, etc) to print the address and symbol
- on its behalf. This content is printed directly to the output stream,
- it does not pass through the i386 disassembler output buffers. As a
- result, we never check this particular output for styling escape
- characters.
-
- In some (not very scientific) benchmarking on my machine,
- disassembling a reasonably large (142M) shared library, I'm not seeing
- any significant slow down in disassembler speed with this change.
-
- Most instructions are now being fully syntax highlighted when I
- disassemble using the --disassembler-color=extended-color option. I'm
- sure that there are probably still a few corner cases that need fixing
- up, but we can come back to them later I think.
-
- When disassembler syntax highlighting is not being used, then there
- should be no user visible changes after this commit.

- Use subclasses of windows_process_info

- Consolidate "Python API" sections in NEWS
- I noticed that the gdb NEWS file had two "Python API" sections in
- "Changes since GDB 12". This patch consolidates the two. I chose to
- preserve the second one, first because it is longer, and second
- because I felt that user command changes should come before API
- changes.
-
- Simplify varobj "change" logic
- varobj used to store 'print_value' as a C string, where NULL was a
- valid value, and so it had logic to handle this situation. However,
- at some point this was changed to be a std::string, and so the code
- can be simplified in this spot.

- [gdb] Name arch selftests more clearly
- When running some all archs selftest I get:
- ...
- $ gdb -q -batch -ex "maint selftest unpack_field_as_long"
- Running selftest unpack_field_as_long::A6.
- ...
-
- By now I know that A6 is an arc architecture, but for others that's less
- clear.
-
- Fix this by using unpack_field_as_long::arc::A6 instead.
-
- This then introduces redundant names like arm::arm, so try to avoid those,
- though I'm not entirely convinced that that's worth the trouble.

-
- The insn is written to gdb_stdout, and there is code in the selftest to add a

-
- The stream() ui_file points into a string buffer, which the disassembler uses

- ...
- There might be a bug that 32-bit fortran truncates 64-bit values to

-
- More concretely, we have:

- $ for arch in i386:x86-64 i386; do \
- gdb -q -batch -ex "set arch $arch" -ex "set lang fortran" \
- -ex "p /x 0xffffffffffffffff"; \

- The target architecture is set to "i386:x86-64".
- $1 = 0xffffffffffffffff
- The target architecture is set to "i386".
- $1 = 0xffffffff

- [gdb/c] Fix type of 2147483648 and literal truncation
- [ Assuming arch i386:x86-64, sizeof (int) == 4,
- sizeof (long) == sizeof (long long) == 8. ]
-
- Currently we have (decimal for 0x80000000):
- ...
- (gdb) ptype 2147483648
- type = unsigned int
- ...
-
- According to C language rules, unsigned types cannot be used for decimal
- constants, so the type should be long instead (reported in PR16377).
-
- Fix this by making sure the type of 2147483648 is long.
-
- The next interesting case is (decimal for 0x8000000000000000):
- ...
- (gdb) ptype 9223372036854775808
- type = unsigned long
- ...
-
- According to the same rules, unsigned long is incorrect.
-
- Current gcc uses __int128 as type, which is allowed, but we don't have that
- available in gdb, so the strict response here would be erroring out with
- overflow.
-
- Older gcc without __int128 support, as well as clang use an unsigned type, but with
- a warning. Interestingly, clang uses "unsigned long long" while gcc uses
- "unsigned long", which seems the better choice.
-
- Given that the compilers allow this as a convience, do the same in gdb
- and keep type "unsigned long", and make this explicit in parser and test-case.
-
- Furthermore, make sure we error out on overflow instead of truncating in all
- cases.

- Tested on x86_64-linux with --enable-targets=all.

- gdb.base/parse_numbers.exp.
-
- Test more interesting values, both in decimal and hex format, as well as
- negative decimals for language modula-2.
-
- This results in an increase in total tests from 15572 to 847448 (55 times

-
- Balance out the increase in runtime by reducing the number of architectures
- tested: only test one architecture per sizeof longlong/long/int/short
- combination, while keeping the possibility intact to run with all
- architectures (through setting a variable in the test-case)
-
- Results in slight reduction of total tests: 15572 -> 13853.

- Document interesting cases in the expected results:
- - wrapping from unsigned to signed
- - truncation
- - PR16377: using unsigned types to represent decimal constants in C

- [gdb] Fix warning in foreach_arch selftests
- When running the selftests, I run into:
- ...
- $ gdb -q -batch -ex "maint selftest"
- ...
- Running selftest execute_cfa_program::aarch64:ilp32.
- warning: A handler for the OS ABI "GNU/Linux" is not built into this
- configuration of GDB. Attempting to continue with the default aarch64:ilp32
- settings.
- ...
- and likewise for execute_cfa_program::i8086 and
- execute_cfa_program::ia64-elf32.
-
- The warning can easily be reproduced outside the selftests by doing:
- ...
- $ gdb -q -batch -ex "set arch aarch64:ilp32"
- ...
- and can be prevented by first doing "set osabi none".
-
- Fix the warning by setting osabi to none while doing selftests that iterate
- over all architectures.
-
- This causes a regression in the print_one_insn selftests for the ARC
- architecture.
-
- The problem is pre-existing, and can be demonstrated (already without this
- patch) using:
- ...
- $ gdb -q -batch -ex "set osabi none" -ex "maint selftest print_one_insn::A6"
- Running selftest print_one_insn::A6.
- Self test failed: Cannot access memory at address 0x0
- Ran 1 unit tests, 1 failed
- $
- ...
-
- For ARC, we use the generic case in print_one_insn_test, containing this code:
- ...
- int kind = gdbarch_breakpoint_kind_from_pc (gdbarch, &pc);
- ...
- insn = gdbarch_sw_breakpoint_from_kind (gdbarch, kind, &bplen);
- ...
-
- The problem is that with osabi linux we trigger:
- ...
- static int
- arc_linux_breakpoint_kind_from_pc (struct gdbarch *gdbarch, CORE_ADDR *pcptr)
- {
- return trap_size;
- }
- ...
- but with osabi none:
- ...
- arc_breakpoint_kind_from_pc (struct gdbarch *gdbarch, CORE_ADDR *pcptr)
- {
- size_t length_with_limm = gdb_insn_length (gdbarch, *pcptr);
- ...
- which needs access to memory, and will consequently fail.
-
- Fix this in print_one_insn_test, in the default case, by iterating over
- supported osabi's to makes sure we trigger arc_linux_breakpoint_kind_from_pc
- which will give us a usable instruction to disassemble.

- gdb: Do not add empty sections to the section map
- From: Ulrich Weigand <ulrich.weigand@de.ibm.com>
-
- build_objfile_section_table () creates four synthetic sections per
- objfile, which are collected by update_section_map () and passed to
- std::sort (). When there are a lot of objfiles, for example, when
- debugging JITs, the presence of these sections slows down the sorting
- significantly.
-
- The output of update_section_map () is used by find_pc_section (),
- which can never return any of these sections: their size is 0, so they
- cannot be accepted by bsearch_cmp ().
-
- Filter them (and all the other empty sections) out in

- gas read_a_source_file #APP processing
- This fixes some horrible code using do_scrub_chars. What we had ran
- text through do_scrub_chars twice, directly in read_a_source_file and
- again via the input_scrub_include_sb call. That's silly, and since
- do_scrub_chars is a state machine, possibly wrong. More silliness is
- evident in the temporary malloc'd buffer for do_scrub_chars output,
- which should have been written directly to sbuf.
-
- So, get rid of the do_scrub_chars call and support functions, leaving
- scrubbing to input_scrub_include_sb. I did wonder about #NO_APP
- overlapping input_scrub_next_buffer buffers, but that should only
- happen if the string starts in one file and finishes in another.

- sb_scrub_and_add_sb not draining input string buffer
- It is possible for sb_scrub_and_add_sb to not consume all of the input
- string buffer. If this happens for reasons explained in the comment,
- do_scrub_chars can leave pointers to the string buffer for the next
- call. This patch fixes that by ensuring the input is drained. Note
- that the behaviour for an empty string buffer is also changed,
- avoiding another do_scrub_chars bug where empty input and single char
- sized output buffers could result in a write past the end of the
- output.

- Use unique_ptr for objfiles

- to do so. However, since then we've rewritten the DWARF reader, and

- gdb, testsuite, fortran: fixup mixed-lang-stack for Intel/LLVM compilers
- When value-printing a pointer within GDB by default GDB will look for
- defined symbols residing at the address of the pointer. For the given
- test the Intel/LLVM compiler stacks both display a symbol associated
- with a printed pointer while the gnu stack does not. This leads to
- failures in the test when running the test with CC_FOR_TARGET='clang'

- g = 0x4ca210 <mixed_func_1a_$OBJ>
-
- For the compiled binary the Intel/LLVM compilers both decide to move the
- local variable g into the .bss section of their executable. The gnu
- stack will keep the variable locally on the stack and not define a
- symbol for it.
-
- Since the behavior for Intel/LLVM is actually expected I adapted the
- testcase at this point to be a bit more allowing for other outputs.
- I added the optional "<SYMBOLNAME>" to the regex testing for g.

- The given changes reduce the test fails for Intel/LLVM stack by 4 each.

-
- Reason for this is that in mixed-lang-stack.cpp in mixed_func_1f an
- object "derived_type obj" goes on the stack which is then passed-by-value
- (so copied) to mixed_func_1g. The default copy-ctor will be called but,
- since derived_type contains a heap allocated string and the copy
- constructor is not implemented it will only be able to shallow copy the
- object. Right after each of the functions the object gets freed - on the
- other hand the d'tor of derived_type actually is implemented and calls
- free on the heap allocated string which leads to a double free. Instead
- of obeying the rule of 3/5 I just got rid of all that since it does not
- serve the test. The string is now just a const char* = ".." object

- testsuite, fortran: allow additional completions in module.exp
- For ifort, ifx, and flang the tests "complete modm" and "complete
- modmany" fail. This is because all three emit additional completion
- suggestions. These additional suggestions have their origin in symbols
- emitted by the compilers which can also be completed from the respective
- incomplete word (modm or modmany). For this specific example gfortran
- does not emit any additional symbols.
-
- For example, in this test the linkage name for var_a in ifx is
- "modmany_mp_var_a_" while gfortran uses "__modmany_MOD_var_a" instead.
- Since modmany_mp_var_a can be completed from modm and also modmany they
- will get displayed, while gfortran's symbol starts with "__" and thus will
- be ignored (it cannot be a completion of a word starting with "m").
-
- Similar things happen in flang and ifort. Some example output is shown
- below:
-
- FLANG
- (gdb) complete p modm
- p modmany

- I want to emphasize: for Fortran (and also C/C++) the complete command
- does not actually check whether its suggestions make sense - all it does
- is look for any symbol (in the minimal symbols, partial symbols etc.)
- that a given substring can be completed to (meaning that the given substring
- is the beginning of the symbol). One can easily produce a similar
- output for the gfortran compiled executable. For this look at the
- slightly modified "complete p mod" in gfortran:
-
- (gdb) complete p mod
- p mod1
- p mod1::var_const
- ...
- p mod_1.c
- p modcounter
- p mode_t
- p modf
- ...
- p modify_ldt
- p modmany
- p modmany::var_a
- p modmany::var_b
- p modmany::var_c
- p modmany::var_i
- p module
- p module.f90
- p module_entry
- p moduse
- p moduse::var_x
- p moduse::var_y
-
- Many of the displayed symbols do not actually work with print:
-
- (gdb) p mode_t
- Attempt to use a type name as an expression
- (gdb) p mod_1.c
- No symbol "mod_1" in current context.
- (gdb)
-
- I think that in the given test the output for gfortran only looks nice
- "by chance" rather than is actually expected. Expected is any output
- that also contains the completions
-
- p modmany
-
- p modmany::var_a
- p modmany::var_b
- p modmany::var_c
- p modmany::var_i
-
- while anythings else can be displayed as well (depending on the
- compiler and its emitted symbols).
-
- This, I'd consider all three outputs as valid and expected - one is just
- somewhat lucky that gfortran does not produce any additional symbols that
- got matched.
-
- The given patch improves test performance for all three compilers
- by allowing additional suggested completions inbetween and after
- the two given blocks in the test. I did not allow additional print
- within the modmany_list block since the output is ordered alphabetically
- and there should normally not appear any additional symbols there.
-
- For flang/ifx/ifort I each see 2 failures less (which are exactly the two
- complete tests).
-
- As a side note and since I mentioned C++ in the beginning: I also tried
- the gdb.cp/completion.exp. The output seems a bit more reasonable,
- mainly since C++ actually has a demangler in place and linkage symbols
- do not appear in the output of complete. Still, with a poor enough
- to-be-completed string one can easily produce similar results:
-
- (gdb) complete p t
- ...
- p typeinfo name for void
- p typeinfo name for void const*
- p typeinfo name for void*
- p typeinfo name for wchar_t
- p typeinfo name for wchar_t const*
- p typeinfo name for wchar_t*
- p t *** List may be truncated, max-completions reached. ***
- (gdb) p typeinfo name for void*
- No symbol "typeinfo" in current context.
- (gdb) complete p B
- p BACK_SLASH
- p BUF_FIRST
- p BUF_LAST
- ...
- p Base
- p Base::Base()
- p Base::get_foo()
- p bad_key_err
- p buf
- p buffer
- p buffer_size
- p buflen
- p bufsize
- p build_charclass.isra
- (gdb) p bad_key_err
- No symbol "bad_key_err" in current context.
-
- (compiled with gcc/g++ and breaking at main).
-
- This patch is only about making the referenced test more 'fair' for the
- other compilers. Generally, I find the behavior of complete a bit
- confusing and maybe one wants to change this at some point but this
- would be a bigger task.

-
- testsuite, fortran: fix info-types for intel compilers
- This info-types.exp test case had a few issues that this patch fixes.
-
- First, the emitted symbol character(kind=1)/character*1 (different
- compilers use different naming converntions here) which is checkedin the
- test is not actually expected given the test program. There is no
- variable of that type in the test. Still, gfortran emits it for every
- Fortran program there is. The reason is the way gfortran handles Fortran's
- named main program. It generates a wrapper around the Fortran program
- that is quite similar to a C main function. This C-like wrapper has
- argc and argv arguments for command line argument passing and the argv
- pointer type has a base type character(kind=1) DIE emitted at CU scope.
-
- Given the program
-
- program prog
- end program prog
-
- the degbug info gfortran emits looks somewhat like
-
- <0><c>: Abbrev Number: 3 (DW_TAG_compile_unit)
- ...
- <1><2f>: Abbrev Number: 4 (DW_TAG_subprogram)
- <30> DW_AT_external : 1
- <30> DW_AT_name : (indirect string, ...): main
- ...
- <2><51>: Abbrev Number: 1 (DW_TAG_formal_parameter)
- <52> DW_AT_name : (indirect string, ...): argc
- ...
- <2><5d>: Abbrev Number: 1 (DW_TAG_formal_parameter)
- <5e> DW_AT_name : (indirect string, ...): argv
- ...
- <62> DW_AT_type : <0x77>
- ...
- <2><6a>: Abbrev Number: 0
- ...
- <1><77>: Abbrev Number: 6 (DW_TAG_pointer_type)
- <78> DW_AT_byte_size : 8
- <79> DW_AT_type : <0x7d>
- <1><7d>: Abbrev Number: 2 (DW_TAG_base_type)
- <7e> DW_AT_byte_size : 1
- <7f> DW_AT_encoding : 8 (unsigned char)
- <80> DW_AT_name : (indirect string, ...): character(kind=1)
- <1><84>: Abbrev Number: 7 (DW_TAG_subprogram)
- <85> DW_AT_name : (indirect string, ...): prog
- ...
-
- Ifx and flang do not emit any debug info for a wrapper main method so
- the type is missing here. There was the possibility of actually adding
- a character*1 type variable to the Fortran executable, but both, ifx and
- gfortran chose to emit this variable's type as a DW_TAG_string_type of
- length one (instead of a character(kind=1), or whatever the respective
- compiler naming convention is). While string types are printed as
- character*LENGHT in the fortran language part (e.g. when issuing a
- 'ptype') they do not generate any symbols inside GDB. In read.c it says
-
- /* These dies have a type, but processing them does not create
- a symbol or recurse to process the children. Therefore we can
- read them on-demand through read_type_die. */
-
- So they did not add any output to 'info types'. Only flang did emit a
- character type here.
- As adding a type would have a) not solved the problem for ifx and would
- have b) somehow hidden the curious behavior of gfortran, instead, the
- check for this character type was chagened to optional with the
- check_optional_entry to allow for the symbols's absence and to allow
- flang and ifx to pass this test as well.
-
- Second, the line checked for s1 was hardcoded as 37 in the test. Given
- that the type is actually defined on line 41 (which is what is emitted by
- ifx) it even seems wrong. The line check for s1 was changed to actually
- check for 41 and a gfortran bug has been filed here
-
- https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105454
-
- The test is now marked as xfail for gfortran.
-
- Third, the whole test of checking for the 'Type s1' in info types seemed
- questionable. The type s1 is declared iside the scope of the Fortran
- program info_types_test. Its DIE however is emitted as a child of the
- whole compilation unit making it visible outside of the program's scope.
- The 'info types' command checks for types stored in the GLOBAL_BLOCK,
- or STATIC_BLOCKm wgucm according to block.h
-
- The GLOBAL_BLOCK contains all the symbols defined in this compilation
- whose scope is the entire program linked together.
- The STATIC_BLOCK contains all the symbols whose scope is the
- entire compilation excluding other separate compilations.
-
- so for gfortran, the type shows up in the output of 'info types'. For
- flang and ifx on the other hand this is not the case. The two compilers
- emit the type (correctly) as a child of the Fortran program, thus not
- adding it to either, the GLOBAL_BLOCK nor the LOCAL_BLOCK. A bug has
- been opened for the gfortran scoping issue:
-
- https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105454
-
- While the most correct change might have been removing the check for s1,
- the change made here was to only check for this type in case of gfortran
- being used as the compiler, as this check also covers the declaration
- line issue mentioned above. A comment was added to maybe remove this
- check once the scoping issue is resolved (and it starts to fail with
- newer gfortran versions). The one used to test these changes was 13.0.

- testsuite/lib: add check_optional_entry for GDBInfoSymbols
- There was already a similar functionality for the GDBInfoModuleSymbols.
- This just extends the GDBInfoSymbols. We will use this feature in a
- later commit to make a testcase less GNU specific and more flexible for
- other compilers.
-
- Namely, in gdb.fortran/info-types.exp currenlty
- GDBInfoSymbols::check_entry is used to verify and test the output of the
- info symbols command. The test, however was written with gfortran as a
- basis and some of the tests are not fair with e.g. ifx and ifort as
- they test for symbols that are not actually required to be emitted. The
- lines
- GDBInfoSymbols::check_entry "${srcfile}" "" "${character1}"
- and
- GDBInfoSymbols::check_entry "${srcfile}" "37" "Type s1;"
-
- check for types that are either not used in the source file (character1)
- or should not be emitted by the compiler at global scope (s1) thus no
- appearing in the info symbols command. In order to fix this we will
- later use the newly introduced check_optional_entry over check_entry.

- gdb/testsuite: add Fortran compiler identification to GDB
- This commit adds a separate Fortran compiler identification mechanism to
- the testsuite, similar to the existing one for C/C++. Before this
- change, the options and version for the Fortran compiler specified when
- running the testsuite with F90_FOR_TARGET set, was detected via its
- respective C compiler. So running the testsuite as
-
- make check TEST=gdb.fortran/*.exp CC_FOR_TARGET=gcc F90_FOR_TARGET=ifx
-
- or even
-
- make check TEST=gdb.fortran/*.exp F90_FOR_TARGET=ifx
-
- would use the gcc compiler inside the procedures get_compiler_info and
- test_compiler_info to identify compiler flags and the compiler version.
- This could sometimes lead to unpredictable outputs. It also limited
- testsuite execution to combinations where C and Fortran compiler would
- come from the same family of compiers (gcc/gfortran, icc/ifort, icx/ifx,
- clang/flang ..). This commit enables GDB to detect C and Fortran
- compilers independently of each other.
-
- As most/nearly all Fortran compilers have a mechanism for preprocessing
- files in a C like fashion we added the exact same meachnism that already
- existed for C/CXX. We let GDB preprocess a file with the compilers
- Fortran preprocessor and evaluate the preprocessor defined macros in that
- file.
-
- This enables GDB to properly run heterogeneous combinations of C and
- Fortran compilers such as
-
- CC_FOR_TARGET='gcc' and F90_FOR_TARGET='ifort'
-
- or enables one to run the testsuite without specifying a C compiler as in
-
- make check TESTS=gdb.fortran/*.exp F90_FOR_TARGET='ifx'
- make check TESTS=gdb.fortran/*.exp F90_FOR_TARGET='flang'
-
- On the other hand this also requires one to always specify a
- identification mechanism for Fortran compilers in the compiler.F90 file.
-
- We added identification for GFORTRAN, FLANG (CLASSIC and LLVM) IFX,
- IFORT, and ARMFLANG for now.
-
- Classic and LLVM flang were each tested with their latest releases on
- their respective release pages. Both get recognized by the new compiler
- identification and we introduced the two names flang-classic and
- flang-llvm to distinguish the two. While LLVM flang is not quite mature
- enough yet for running the testsuite we still thought it would be a good
- idea to include it already. For this we added a case for the fortran_main
- procedure. LLVM flang uses 'MAIN__' as opposed to classic flang which
- uses 'MAIN_' here.
-
- We did not have the possibility to test ARMFLANG - the versioning scheme
- here was extracted from its latest online documentation.
-
- We changed the test_compiler_info procedure to take another optional
- argument, the language string, which will be passed though to the
- get_compiler_info procedure. Passing 'f90' or 'c++' here will then
- trigger the C++/Fortran compiler identification within
- get_compiler_info. The latter procedure was extended to also handle
- the 'f90' argument (similarly to the already existing 'c++' one).

-
- gdb/testsuite: move getting_compiler_info to front of gdb_compile
- The procedure gdb_compile queries its options via
-
- [lsearch -exact $options getting_compiler_info]
-
- to check whether or not it was called in with the option
- getting_compiler_info. If it was called with this option it would
- preprocess some test input to try and figure out the actual compiler
- version of the compiler used. While doing this we cannot again try to
- figure out the current compiler version via the 'getting_compiler_info'
- option as this would cause infinite recursion. As some parts of the
- procedure do recursively test for the compiler version to e.g. set
- certain flags, at several places gdb_compile there are checks for the
- getting_compiler_info option needed.
-
- In the procedure, there was already a variable 'getting_compiler_info'
- which was set to the result of the 'lsearch' query and used instead of
- again and again looking for getting_compiler_info in the procedure
- options. But, this variable was actually set too late within the code.
- This lead to a mixture of querying 'getting_compiler_info' or
- doing an lserach on the options passed to the procedure.
-
- I found this inconsistent and instead moved the variable
- getting_compiler_info to the front of the procedure. It is set to true
- or false depending on whether or not the argument is found in the
- procedure's options (just as before) and queried instead of doing an
- lsearch on the procedure options in the rest of the procedure.

-
- over 10 years ago. The last .f files in the testsuite by now are all
- being compiled by passing 'f90' to the GDB compile, thus only actually
- using F90_FOR_TARGET (array-element.f, block-data.f, subarray.f).
- Gfortran in this case is backwards compatible with most f77 code as
- claimed on gcc.gnu.org/fortran.
-
- The reason we'd like to get rid of this now is, that we'll be
- implementing a Fortran compiler identification mechanism, similar to the
- C/Cpp existing ones. It would be using the Fortran preprocessor macro
- defines to identify the Fortran compiler version at hand. We found it
- inconsequent to only implement this for f90 but, on the other hand, f77
- seems deprecated. So, with this commit we remove the remaining lines for
- its support.

- gdb/manual: Introduce location specs
- The current "Specify Location" section of the GDB manual starts with:
-
- "Several @value{GDBN} commands accept arguments that specify a location
- of your program's code."
-
- And then, such commands are documented as taking a "location"
- argument. For example, here's a representative subset:
-
- @item break @var{location}
- @item clear @var{location}
- @item until @var{location}
- @item list @var{location}
- @item edit @var{location}
- @itemx info line @var{location}
- @item info macros @var{location}
- @item trace @var{location}
- @item info scope @var{location}
- @item maint agent @r{[}-at @var{location}@r{,}@r{]} @var{expression}
-
- The issue here is that "location" isn't really correct for most of
- these commands. Instead, the "location" argument is really a
- placeholder that represent an umbrella term for all of the
- "linespecs", "explicit location", and "address location" input
- formats. GDB parses these and then finds the actual code locations
- (plural) in the program that match. For example, a "location"
- specified like "-function func" will actually match all the code
- locations in the program that correspond to the address/file/lineno of
- all the functions named "func" in all the loaded programs and shared
- libraries of all the inferiors. A location specified like "-function
- func -label lab" matches all the addresses of C labels named "lab" in
- all functions named "func". Etc.
-
- This means that several of the commands that claim they accept a
- "location", actually end up working with multiple locations, and the
- manual doesn't explain that all that well. In some cases, the command
- will work with all the resolved locations. In other cases, the
- command aborts with an error if the location specification resolves to
- multiple locations in the program. In other cases, GDB just
- arbitrarily and silently picks whatever is the first resolved code
- location (which sounds like should be improved).
-
- To clarify this, I propose we use the term "Location Specification",
- with shorthand "locaction spec", when we're talking about the user
- input, the argument or arguments that is/are passed to commands to
- instruct GDB how to find locations of interest. This is distinct from
- the actual code locations in the program, which are what GDB finds
- based on the user-specified location spec. Then use "location
- specification or the shorter "location spec" thoughout instead of
- "location" when we're talking about the user input.
-
- Thus, this commit does the following:
-
- - renames the "Specify Location" section of the manual to "Location
- Specifications".
-
- - It then introduces the term "Location Specification", with
- corresponding shorthand "location spec", as something distinct from
- an actual code location in the program. It explains what a concrete
- code location is. It explains that a location specification may be
- incomplete, and that may match multiple code locations in the
- program, or no code location at all. It gives examples. Some
- pre-existing examples were moved from the "Set Breaks" section, and
- a few new ones that didn't exist yet were added. I think it is
- better to have these centralized in this "Location Specification"
- section, since all the other commands that accept a location spec
- have an xref that points there.
-
- - Goes through the manual, and where "@var{location}" was used for a
- command argument, updated it to say "@var{locspec}" instead. At the
- same time, tweaks the description of the affected commands to
- describe what happens when the location spec resolves to more than
- one location. Most commands just did not say anything about that.
-
- One command -- "maint agent -at @var{location}" -- currently says it
- accepts a "location", suggesting it can accept address and explicit
- locations too, but that's incorrect. In reality, it only accepts
- linespecs, so fix it accordingly.
-
- One MI command -- "-trace-find line" -- currently says it accepts a
- "line specification", but it can accept address and explicit
- locations too, so fix it accordingly.
-
- Special thanks goes to Eli Zaretskii for reviews and rewording
- suggestions.

- This patch accomplishes this and enables a 32-bit build with

-
- Moving the bpf, tilegx and loongarch files to the correct list means GDB can

- gdb/python: improve formatting of help text for user defined commands
- Consider this command defined in Python (in the file test-cmd.py):
-
- class test_cmd (gdb.Command):
- """
- This is the first line.
- Indented second line.
- This is the third line.
- """
-
- def __init__ (self):
- super ().__init__ ("test-cmd", gdb.COMMAND_OBSCURE)
-
- def invoke (self, arg, from_tty):
- print ("In test-cmd")
-
- test_cmd()
-
- Now, within a GDB session:
-
- (gdb) source test-cmd.py
- (gdb) help test-cmd
-
- This is the first line.
- Indented second line.
- This is the third line.
-
- (gdb)
-
- I think there's three things wrong here:
-
- 1. The leading blank line,
- 2. The trailing blank line, and
- 3. Every line is indented from the left edge slightly.
-
- The problem of course, is that GDB is using the Python doc string
- verbatim as its help text. While the user has formatted the help text
- so that it appears clear within the .py file, this means that the text
- appear less well formatted when displayed in the "help" output.
-
- The same problem can be observed for gdb.Parameter objects in their
- set/show output.
-
- In this commit I aim to improve the "help" output for commands and
- parameters.
-
- To do this I have added gdbpy_fix_doc_string_indentation, a new
- function that rewrites the doc string text following the following
- rules:
-
- 1. Leading blank lines are removed,
- 2. Trailing blank lines are removed, and
- 3. Leading whitespace is removed in a "smart" way such that the
- relative indentation of lines is retained.
-
- With this commit in place the above example now looks like this:
-
- (gdb) source ~/tmp/test-cmd.py
- (gdb) help test-cmd
- This is the first line.
- Indented second line.
- This is the third line.
- (gdb)
-
- Which I think is much neater. Notice that the indentation of the
- second line is retained. Any blank lines within the help text (not
- leading or trailing) will be retained.
-
- I've added a NEWS entry to note that there has been a change in
- behaviour, but I didn't update the manual. The existing manual is
- suitably vague about how the doc string is used, so I think the new
- behaviour is covered just as well by the existing text.

- gdb: use gdb::unique_xmalloc_ptr<char> for docs in cmdpy_init
- Make use of gdb::unique_xmalloc_ptr<char> to hold the documentation
- string in cmdpy_init (when creating a custom GDB command in Python).
- I think this is all pretty straight forward, the only slight weirdness
- is the removal of the call to free toward the end of this function.
-
- Prior to this commit, if an exception was thrown after the GDB command
- was created then we would (I think) end up freeing the documentation
- string even though the command would remain registered with GDB, which
- would surely lead to undefined behaviour.
-
- After this commit we release the doc string at the point that we hand
- it over to the command creation routines. If we throw _after_ the
- command has been created within GDB then the doc string will be left
- live. If we throw during the command creation itself (either from
- add_prefix_cmd or add_cmd) then it is up to those functions to free
- the doc string (I suspect we don't, but I think in general the
- commands are pretty bad at cleaning up after themselves, so I don't
- think this is a huge problem).

- opcodes/i386: remove trailing whitespace from insns with zero operands
- While working on another patch[1] I had need to touch this code in
- i386-dis.c:
-
- ins->obufp = ins->mnemonicendp;
- for (i = strlen (ins->obuf) + prefix_length; i < 6; i++)
- oappend (ins, " ");
- oappend (ins, " ");
- (*ins->info->fprintf_styled_func)
- (ins->info->stream, dis_style_mnemonic, "%s", ins->obuf);
-
- What this code does is add whitespace after the instruction mnemonic
- and before the instruction operands.
-
- The problem I ran into when working on this code can be seen by
- assembling this input file:
-
- .text
- nop
- retq
-
- Now, when I disassemble, here's the output. I've replaced trailing
- whitespace with '_' so that the issue is clearer:
-
- Disassembly of section .text:
-
- 0000000000000000 <.text>:
- 0: 90 nop
- 1: c3 retq___
-
- Notice that there's no trailing whitespace after 'nop', but there are
- three spaces after 'retq'!
-
- What happens is that instruction mnemonics are emitted into a buffer
- instr_info::obuf, then instr_info::mnemonicendp is setup to point to
- the '\0' character at the end of the mnemonic.
-
- When we emit the whitespace, this is then added starting at the
- mnemonicendp position. Lets consider 'retq', first the buffer is
- setup like this:
-
- 'r' 'e' 't' 'q' '\0'
-
- Then we add whitespace characters at the '\0', converting the buffer
- to this:
-
- 'r' 'e' 't' 'q' ' ' ' ' ' ' '\0'
-
- However, 'nop' is actually an alias for 'xchg %rax,%rax', so,
- initially, the buffer is setup like this:
-
- 'x' 'c' 'h' 'g' '\0'
-
- Then in NOP_Fixup we spot that we have an instruction that is an alias
- for 'nop', and adjust the buffer to this:
-
- 'n' 'o' 'p' '\0' '\0'
-
- The second '\0' is left over from the original buffer contents.
- However, when we rewrite the buffer, we don't afjust mnemonicendp,
- which still points at the second '\0' character.
-
- Now, when we insert whitespace we get:
-
- 'n' 'o' 'p' '\0' ' ' ' ' ' ' ' ' '\0'
-
- Notice the whitespace is inserted after the first '\0', so, when we
- print the buffer, the whitespace is not printed.
-
- The fix for this is pretty easy, I can change NOP_Fixup to adjust
- mnemonicendp, but now a bunch of tests start failing, we now produce
- whitespace after the 'nop', which the tests don't expect.
-
- So, I could update the tests to expect the whitespace....
-
- ...except I'm not a fan of trailing whitespace, so I'd really rather
- not.
-
- Turns out, I can pretty easily update the whitespace emitting code to
- spot instructions that have zero operands and just not emit any
- whitespace in this case. So this is what I've done.
-
- I've left in the fix for NOP_Fixup, I think updating mnemonicendp is
- probably a good thing, though this is not really required any more.
-
- I've then updated all the tests that I saw failing to adjust the
- expected patterns to account for the change in whitespace.

- Replace bfd_hostptr_t with uintptr_t
- bfd_hostptr_t is defined as a type large enough to hold either a long
- or a pointer. It mostly appears in the coff backend code in casts.
- include/coff/internal.h struct internal_syment and union
- internal_auxent have the only uses in data structures, where
- comparison with include/coff/external.h and other code reveals that
- the type only needs to be large enough for a 32-bit integer or a
- pointer. That should mean replacing with uintptr_t is OK.
-
- Remove much of BFD_HOST configury
- This patch removes the definition of bfd_uint64_t and bfd_int64_t as
- well as most BFD_HOST_* which are now unused.
-
- Remove use of bfd_uint64_t and similar
- Requiring C99 means that uses of bfd_uint64_t can be replaced with
- uint64_t, and similarly for bfd_int64_t, BFD_HOST_U_64_BIT, and
- BFD_HOST_64_BIT. This patch does that, removes #ifdef BFD_HOST_*
- and tidies a few places that print 64-bit values.

- gdb: Require psymtab before calling quick_functions in objfile
- The recent DWARF indexer rewrite introduced a regression when debugging
- a forking program.
-
- Here is a way to reproduce the issue (there might be other ways, but one
- is enough and this one mimics the situation we encountered). Consider a
- program which forks, and the child loads a shared library and calls a
- function in this shared library:
-
- if (fork () == 0)
- {
- void *solib = dlopen (some_solib, RTLD_NOW);
- void (*foo) () = dlsym (some_solib, "foo");
- foo ();
- }
-
- Suppose that this program is compiled without debug info, but the shared
- library it loads has debug info enabled.
-
- When debugging such program with the following options:
-
- - set detach-on-fork off
- - set follow-fork-mode child
-
- we see something like:
-
- (gdb) b foo
- Function "foo" not defined.
- Make breakpoint pending on future shared library load? (y or [n]) y
- Breakpoint 1 (foo) pending.
- (gdb) run
- Starting program: a.out
- [Attaching after process 19720 fork to child process 19723]
- [New inferior 2 (process 19723)]
- [Switching to process 19723]
-
- Thread 2.1 "a.out" hit Breakpoint 1, 0x00007ffff7fc3101 in foo () from .../libfoo.so

- ---------------------
- A fatal error internal to GDB has been detected, further
- debugging is not possible. GDB will now terminate.
-
- This is a bug, please report it. For instructions, see:
- <https://www.gnu.org/software/gdb/bugs/>.
-
- The first issue observed is in the message printed when hitting the
- breakpoint. It says that there was a break in the .so file as if there
- was no debug info associated with it, but there is. Later, if we try to
- display the source where the execution stopped, we have a segfault.
-
- Note that not having the debug info on the main binary is not strictly
- required to encounter some issues, it only is to encounter the segfault.
- If the main binary has debug information, GDB shows some source form the
- main binary, unrelated to where we stopped.
-
- The core of the issue is that GDB never loads the psymtab for the
- library. It is not loaded when we first see the .so because in case of
- detach-on-fork off, follow-fork-mode child, infrun.c sets
- child_inf->symfile_flags = SYMFILE_NO_READ to delay the psymtab loading
- as much as possible. If we compare to what was done to handle this
- before the new indexer was activated, the psymatb construction for the
- shared library was done under
- psymbol_functions::expand_symtabs_matching:
-
- bool
- psymbol_functions::expand_symtabs_matching (...)
- {
- for (partial_symtab *ps : require_partial_symbols (objfile))
- ...
- }
-
- The new indexer's expand_symtabs_matching callback does not have a call
- to the objfile's require_partial_symbols, so if the partial symbol table
- is not loaded at this point, there is no mechanism to fix this.
-
- Instead of requiring each implementation of the quick_functions to check
- that partial symbols have been read, I think it is safer to enforce this
- when calling the quick functions. The general pattern for calling the
- quick functions is:
-
- for (auto *iter : qf)
- iter->the_actual_method_call (...)
-
- This patch proposes to wrap the access of the `qf` field with an accessor
- which ensures that partial symbols have been read before iterating:
- qf_require_partial_symbols. All calls to quick functions are updated
- except:
-
- - quick_functions::dump
- - quick_functions::read_partial_symbols (from
- objfile::require_partial_symbols)
- - quick_functions::can_lazily_read_symbols and quick_functions::has_symbols
- (from objfile::has_partial_symbols)
-
- Regression tested on x86_64-gnu-linux.

- Fix crash in new DWARF indexer
- PR gdb/29128 points out a crash in the new DWARF index code. This
- happens if the aranges for a CU claims a PC, but the symtab that is
- created during CU expansion does not actually contain the PC. This
- can only occur due to bad debuginfo, but at the same time, gdb should
- not crash.
-
- This patch fixes the bug and further merges some code into
- dwarf2_base_index_functions. This merger helps prevent the same issue
- from arising from the other index implementations.

-
- Finalize each cooked index separately
- After DWARF has been scanned, the cooked index code does a
- "finalization" step in a worker thread. This step combines all the
- index entries into a single master list, canonicalizes C++ names, and
- splits Ada names to synthesize package names.
-
- While this step is run in the background, gdb will wait for the
- results in some situations, and it turns out that this step can be
- slow. This is PR symtab/29105.
-
- This can be sped up by parallelizing, at a small memory cost. Now
- each index is finalized on its own, in a worker thread. The cost
- comes from name canonicalization: if a given non-canonical name is
- referred to by multiple indices, there will be N canonical copies (one
- per index) rather than just one.
-
- This requires changing the users of the index to iterate over multiple
- results. However, this is easily done by introducing a new "chained
- range" class.
-
- When run on gdb itself, the memory cost seems rather low -- on my
- current machine, "maint space 1" reports no change due to the patch.
-
- For performance testing, using "maint time 1" and "file" will not show
- correct results. That approach measures "time to next prompt", but
- because the patch only affects background work, this shouldn't (and
- doesn't) change. Instead, a simple way to make gdb wait for the
- results is to set a breakpoint.
-
- Before:
-

- arm: avoid use of GNU builtin function in s_arm_unwind_save_mixed
- Whilst reviewing Luis' proposed change to s_arm_unwind_save_mixed
- yesterday I noticed that we were making use of __builting_clzl
- directly within the main function, which is not guaranteed to be
- portable. Whilst studying the code further, I also realized that it
- could be rewritten without using it and also reworked to remove a lot
- of unnecessary iterations steps. So this patch does that (and also
- removes the source of the warning that Luis was trying to fix).
- Finally, with the rewrite we can also simplify the caller of this
- routine as the new version can handle all the cases directly.
-
- * config/tc-arm.c (s_arm_unwind_save_mixed): Rewrite without
- using __builtin_clzl.
- (s_arm_unwind_save): Simplify logic for simple/mixed register saves.

- Show enabled locations with disabled breakpoint parent as "y-"
- Currently, breakpoint locations that are enabled while their parent
- breakpoint is disabled are displayed with "y" in the Enb colum of
- "info breakpoints":
-
- (gdb) info breakpoints
- Num Type Disp Enb Address What
- 1 breakpoint keep n <MULTIPLE>
- 1.1 y 0x00000000000011b6 in ...
- 1.2 y 0x00000000000011c2 in ...
- 1.3 n 0x00000000000011ce in ...
-
- Such locations won't trigger a break, so to avoid confusion, show "y-"
- instead. For example:
-
- (gdb) info breakpoints
- Num Type Disp Enb Address What
- 1 breakpoint keep n <MULTIPLE>
- 1.1 y- 0x00000000000011b6 in ...

- 1.3 n 0x00000000000011ce in ...
-
- The "-" sign is inspired on how the TUI represents breakpoints on the
- left side of the source window, with "b-" for a disabled breakpoint.

- gdb: Fix DUPLICATE and PATH regressions throughout
- The previous patch to add -prompt/-lbl to gdb_test introduced a
- regression: Before, you could specify an explicit empty message to
- indicate you didn't want to PASS, like so:
-
- gdb_test COMMAND PATTERN ""
-
- After said patch, gdb_test no longer distinguishes
- no-message-specified vs empty-message, so tests that previously would
- be silent on PASS, now started emitting PASS messages based on
- COMMAND. This in turn introduced a number of PATH/DUPLICATE
- violations in the testsuite.
-
- This commit fixes all the regressions I could see.
-
- This patch uses the new -nopass feature introduced in the previous
- commit, but tries to avoid it if possible. Most of the patch fixes
- DUPLICATE issues the usual way, of using with_test_prefix or explicit
- unique messages.
-
- See previous commit's log for more info.
-
- In addition to looking for DUPLICATEs, I also looked for cases where
- we would now end up with an empty message in gdb.sum, due to a
- gdb_test being passed both no message and empty command. E.g., this
- in gdb.ada/bp_reset.exp:
-
- gdb_run_cmd
- gdb_test "" "Breakpoint $decimal, foo\\.nested_sub \\(\\).*"
-
- was resulting in this in gdb.sum:
-
- PASS: gdb.ada/bp_reset.exp:
-
- I fixed such cases by passing an explicit message. We may want to
- make such cases error out.
-
- Tested on x86_64 GNU/Linux, native and native-extended-gdbserver. I
- see zero PATH cases now. I get zero DUPLICATEs with native testing
- now. I still see some DUPLICATEs with native-extended-gdbserver, but
- those were preexisting, unrelated to the gdb_test change.

-
- Add -nopass option to gdb_test/gdb_test_multiple
- The previous patch to add -prompt/-lbl to gdb_test introduced a
- regression: Before, you could specify an explicit empty message to
- indicate you didn't want to PASS, like so:
-
- gdb_test COMMAND PATTERN ""
-
- After said patch, gdb_test no longer distinguishes
- no-message-specified vs empty-message, so tests that previously would
- be silent on PASS, now started emitting PASS messages based on
- COMMAND. This in turn introduced a number of PATH/DUPLICATE
- violations in the testsuite.
-
- I think that not issuing a PASS should be restricted to only a few
- cases -- namely in shared routines exported by gdb.exp, which happen
- to use gdb_test internally. In tests that iterate an unknown number
- of tests exercising some racy scenario. In the latter case, if we
- emit PASSes for each iteration, we run into the situation where
- different testsuite runs emit a different number of PASSes.
-
- Thus, this patch preserves the current behavior, and, instead, adds a
- new "-nopass" option to gdb_test and gdb_test_no_output. Compared to
- the old way of supressing PASS with an empty message, this has the
- advantage that you can specify a FAIL message that is distinct from
- the command string, and, it's also more explicit.

- [gdb/testsuite] Fix gdb.opt/clobbered-registers-O2.exp with clang
- When running test-case gdb.opt/clobbered-registers-O2.exp with clang 12.0.1, I

- ...
- (gdb) run ^M

- 31 return *start_sequence(operand0, operand1);^M
- (gdb) FAIL: gdb.opt/clobbered-registers-O2.exp: runto: run to start_sequence
- ...
-
- The problem is that the breakpoint in start_sequence doesn't trigger, because:
- - the call to start_sequence in gen_movsd is optimized away, despite the
- __attribute__((noinline)), so the actual function start_sequence doesn't get
- called, and
- - the debug info doesn't contain inlined function info, so there's only one
- breakpoint location.
-
- Adding noclone and noipa alongside the noinline attribute doesn't fix this.
-
- Adding the clang-specific attribute optnone in start_sequence does, but since
- it inhibits all optimization, that's not a preferred solution in a gdb.opt
- test-case, and it would work only for clang and not other compilers that
- possibly have the same issue.
-
- Fix this by moving functions start_sequence and gen_movsd into their own
- files, as a way of trying harder to enforce noinline/noipa/noclone.

-
- For non-artifical functions, DW_AT_name attribute should contains the name

- (Ref# http://wiki.dwarfstd.org/index.php?title=Best_Practices)
- Since artificial functions are not present in actual program they not having

-
- Currently GDB is invalidating any function not havnig DW_AT_name which is why

- Rename base_breakpoint -> code_breakpoint
- Even after the previous patches reworking the inheritance of several
- breakpoint types, the present breakpoint hierarchy looks a bit
- surprising, as we have "breakpoint" as the superclass, and then
- "base_breakpoint" inherits from "breakpoint". Like so, simplified:
-
- breakpoint
- base_breakpoint
- ordinary_breakpoint
- internal_breakpoint
- momentary_breakpoint
- ada_catchpoint
- exception_catchpoint
- tracepoint
- watchpoint
- catchpoint
- exec_catchpoint
- ...
-
- The surprising part to me is having "base_breakpoint" being a subclass
- of "breakpoint". I'm just refering to naming here -- I mean, you'd
- expect that it would be the top level baseclass that would be called
- "base".
-
- Just flipping the names of breakpoint and base_breakpoint around
- wouldn't be super great for us, IMO, given we think of every type of
- *point as a breakpoint at the user visible level. E.g., "info
- breakpoints" shows watchpoints, tracepoints, etc. So it makes to call
- the top level class breakpoint.
-
- Instead, I propose renaming base_breakpoint to code_breakpoint. The
- previous patches made sure that all code breakpoints inherit from
- base_breakpoint, so it's fitting. Also, "code breakpoint" contrasts
- nicely with a watchpoint also being typically known as a "data
- breakpoint".
-
- After this commit, the resulting hierarchy looks like:
-
- breakpoint
- code_breakpoint
- ordinary_breakpoint
- internal_breakpoint
- momentary_breakpoint
- ada_catchpoint
- exception_catchpoint
- tracepoint
- watchpoint
- catchpoint
- exec_catchpoint
- ...
-
- ... which makes a lot more sense to me.
-
- I've left this patch as last in the series in case people want to
- bikeshed on the naming.
-
- "code" has a nice property that it's exactly as many letters as
- "base", so this patch didn't require any reindentation. :-)

- Make sure momentary breakpoints are always thread-specific
- This adds a new ctor to momentary_breakpoints with a few parameters
- that are always necessary for momentary breakpoints.
-
- In particular, I noticed that set_std_terminate_breakpoint doesn't
- make the breakpoint be thread specific, which looks like a bug to me.
-
- The point of that breakpoint is to intercept std::terminate calls that
- happen as result of the called thread throwing an exception that won't

- std::terminate, IMO, it's no different from some other thread calling

- Make catchpoint inherit breakpoint, eliminate init_raw_breakpoint
- struct catchpoint's ctor currently calls init_raw_breakpoint, which is
- a bit weird, as that ctor-like function takes a sal argument, but
- catchpoints don't have code locations.
-
- Instead, make struct catchpoint's ctor add the catchpoint's dummy
- location using add_dummy_location.
-
- init_raw_breakpoint uses add_location under the hood, and with a dummy
- sal it would ultimately use the breakpoint's gdbarch for the
- location's gdbarch, so replace the references to loc->gdbarch (which
- is now NULL) in syscall_catchpoint to references to the catchpoint's
- gdbarch.
-
- struct catchpoint's ctor was the last user of init_raw_breakpoint, so
- this commit eliminates the latter.
-
- Since catchpoint locations aren't code locations, make struct
- catchpoint inherit struct breakpoint instead of base_breakpoint. This
- let's us delete the tracepoint::re_set override too.

- Make breakpoint_address_bits look at the location kind

- Make a few functions work with base_breakpoint instead of breakpoint
- This makes tracepoints inherit from base_breakpoint, since their
- locations are code locations. If we do that, then we can eliminate
- tracepoint::re_set and tracepoint::decode_location, as they are doing
- the same as the base_breakpoint implementations.
-
- With this, all breakpoint types created by new_breakpoint_from_type
- are code breakpoints, i.e., base_breakpoint subclasses, and thus we
- can make it return a base_breakpoint pointer.
-
- Finally, init_breakpoint_sal can take a base_breakpoint pointer as
- "self" pointer too. This will let us convert this function to a
- base_breakpoint ctor in a following patch.

-
- ranged_breakpoint: don't use init_raw_breakpoint
- ranged_breakpoint's ctor already sets the breakpoint's type to
- bp_hardware_breakpoint.
-
- Since this is a "regular" breakpoint, b->pspace should remain NULL.
-
- Thus, the only thing init_raw_breakpoint is needed for, is to add the
- breakpoint's location. Do that directly.

-
- PowerPC: Make test gdb.arch/powerpc-power10.exp Endian independent.
- The .quad statement stores the 64-bit hex value in Endian order. When used
- to store a 64-bit prefix instructions on Big Endian (BE) systems, the .quad
- statement stores the 32-bit suffix followed by the 32-bit prefix rather
- than the expected order of prefix word followed by the suffix word. GDB
- fetches 32-bits at a time when disassembling instructions. The disassembly
- on BE gets messed up since GDB fetches the suffix first and interprets it
- as a word instruction not a prefixed instruction. When gdb fetches the
- prefix part of the instruction, following the initial suffix word, gdb
- associates the prefix word incorrectly with the following 32-bits as the
- suffix for the instruction when in fact it is the following instruction.
-
- For example on BE we have two prefixed instructions stored using the
- .quad statement as follows:
-
- addr word GDB action
- ---------------------------------------------
- 1 suffix inst A <- GDB interprets as a word instruction
- 2 prefix inst A <- GDB uses this prefix with
-
- 3 suffix inst B <- this suffix rather than the suffix at addr 1.
- 4 prefix inst B
-
- This patch changes the .quad statement into two .longs to explicitly store
- the prefix followed by the suffix of the instruction.
-
- The patch rearranges the instructions to put all of the word instructions
- together followed by the prefix instructions for clarity.
-
- The patch has been tested on Power 10 and Power 7 BE and LE to verify
- the change works as expected.

- add a trie to map quickly from address range to compilation unit
- When using perf to profile large binaries, _bfd_dwarf2_find_nearest_line()
- becomes a hotspot, as perf wants to get line number information
- (for inline-detection purposes) for each and every sample. In Chromium
- in particular (the content_shell binary), this entails going through
- 475k address ranges, which takes a long time when done repeatedly.
-
- Add a radix-256 trie over the address space to quickly map address to
- compilation unit spaces; for content_shell, which is 1.6 GB when some
- (but not full) debug information turned is on, we go from 6 ms to
- 0.006 ms (6 µs) for each lookup from address to compilation unit, a 1000x
- speedup.
-
- There is a modest RAM increase of 180 MB in this binary (the existing
- linked list over ranges uses about 10 MB, and the entire perf job uses
- between 2–3 GB for a medium-size profile); for smaller binaries with few
- ranges, there should be hardly any extra RAM usage at all.

- gdbsupport: fix path_join crash with -std=c++17 and -D_GLIBCXX_DEBUG
- When building GDB with -std=c++17 and -D_GLIBCXX_DEBUG=1, I get:
-
- $ ./gdb -nx --data-directory=data-directory -q -ex "maint selftest path_join"
- /usr/include/c++/11.2.0/string_view:233: constexpr const value_type& std::basic_string_view<_CharT, _Traits>::operator[](std::basic_string_view<_CharT, _Traits>::size_type) const [with _CharT = char; _Traits = std::char_traits<char>; std::basic_string_view<_CharT, _Traits>::const_reference = const char&; std::basic_string_view<_CharT, _Traits>::size_type = long unsigned int]: Assertion '__pos < this->_M_len' failed.
-
- The problem is that we're passing an empty string_view to
- IS_ABSOLUTE_PATH. IS_ABSOLUTE_PATH accesses [0] on that string_view,
- which is out-of-bounds.
-
- The reason this is not seen with -std less than c++17 is that our local
- copy of string_view (used with C++ < 17) does not have the assert in
- operator[], as that wouldn't work in a constexpr method:
-
- https://gitlab.com/gnutools/binutils-gdb/-/blob/5890af36e5112bcbb8d7555e63570f68466e6944/gdbsupport/gdb_string_view.h#L180
-
- IS_ABSOLUTE_PATH is normally used with null-terminated string. It's
- fine to pass an empty null-terminated string to IS_ABSOLUTE_PATH,
- because index 0 in such a string is valid. But not with an empty
- string_view.
-
- Fix that by avoiding the "call" to IS_ABSOLUTE_PATH if the string_view
- is empty.

- don't over-align file positions of PE executable sections
- When a sufficiently small alignment was specified via --file-alignment,
- individual section alignment shouldn't affect placement within the file.
- This involves first of all clearing D_PAGED for images when section and
- file alignment together don't permit paging of the image. The involved
- comparison against COFF_PAGE_SIZE in turn helped point out (through a
- compiler warning) that 'page_size' should be of unsigned type (as in
- particular FileAlignment is). This yet in turn pointed out a dubious
- error condition (which is being deleted).
-
- For the D_PAGED case I think the enforced file alignment may still be
- too high, but I'm wary of changing that logic without knowing of
- possible corner cases.
-
- Furthermore file positions in PE should be independent of the alignment
- recorded in section headers anyway. Otherwise there are e.g. anomalies
- following commit 6f8f6017a0c4 ("PR27567, Linking PE files adds alignment
- section flags to executables") in that linking would use information a
- subsequent processing step (e.g. stripping) wouldn't have available
- anymore, and hence a binary could change in that 2nd step for no actual
- reason. (Similarly stripping a binary linked with a linker pre-dating
- that commit would change the binary again when stripping it a 2nd time.)

- gas: avoid octal numbers being accepted when processing .linefile
- Compilers would put decimal numbers there, so I think we should treat
- finding octal numbers the same as finding bignums - ignore them as
- actually being comments of some very specific form.
-
-2022-05-18 Jan Beulich <jbeulich@suse.com>
-
- gas: avoid bignum related errors when processing .linefile
- Any construct which to the scrubber looks like a C preprocessor
- line/file "directive" is converted to .linefile, but the amount of
- checking the scrubber does is minimal (albeit it does let through only
- decimal digits for the line part of the contruct). Since the scrubber
- conversion is further tied to # being a line comment character, anything
- which upon closer inspection turns out not to be a line/file "directive"
- is supposed to be treated as a comment, i.e. ignored. Therefore we
- cannot use get_absolute_expression(), as this may raise errors. Open-
- code the function instead, treating everything not resulting in
- O_constant as a comment as well.
-
- Furthermore also bounds-check the parsed value. This bounds check tries
- to avoid implementation defined behavior (which may be the raising of an
- implementation defined signal), but for now makes the assumption that
- int has less than 64 bits. The way bfd_signed_vma (which is what offsetT
- aliases) is defined in bfd.h for the BFD64 case I cannot really see a
- clean way of avoiding this assumption. Omitting the #ifdef, otoh, would
- risk "condition is always false" warnings by compilers.
-
- Convert get_linefile_number() to return bool at this occasion as well.

- gas: fold do_repeat{,_with_expander}()
- do_repeat_with_expander() already deals with the "no expander" case
- quite fine, so there's really little point having two functions. What it
- lacks compared with do_repeat() is a call to sb_build(), which can
- simply be moved (and the then redundant sb_new() be avoided). Along with
- this moving also flip if the main if()'s condition such that the "no
- expander" case is handled first.
-
- gas: don't ignore .linefile inside false conditionals
- When assembling code previously pre-processed by a C compiler, long
- enough comments may have been collapsed into "# <line> <file>"
- constructs. If we skip these, line numbers (and possibly even file
- names) will be off / wrong in both diagnostics and debug info.
-
- gas: simplify ignore_input()
- First of all convert to switch(), in preparation of adding another
- directive here which may not be ignored. While doing so drop dead code:
- A string the first two characters of which do not match "if" also wont
- match "ifdef" or "ifndef".
-
- gas: tweak .irp and alike file/line handling for M68K/MRI

- disconnect^M
- Ending remote debugging.^M
- (gdb) FAIL: gdb.python/py-connection.exp: kill the inferior

-
- Make gdb_test's question non-optional if specified
- gdb_test supports handling scenarios where GDB asks a question before
- finishing handling some command. The full prototype of gdb_test is:
-
- # gdb_test COMMAND PATTERN MESSAGE QUESTION RESPONSE
-
- However, QUESTION is a question that GDB _may_ ask, not one that GDB
- _must_ ask:
-
- # QUESTION is a question GDB may ask in response to COMMAND, like
- # "are you sure?"
- # RESPONSE is the response to send if QUESTION appears.
-
- If GDB doesn't raise the question, the test still passes.
-
- I think that this is a misfeature. If GDB regresses and stops asking
- a question, the testsuite won't notice. So I think that if a QUESTION
- is specified, gdb_test should ensure it comes out of GDB.
-
- Running the testsuite exposed a number of tests that pass
- QUESTION/RESPONSE to GDB, but no question comes out. The previous
- commits fixed them all, so this commit changes gdb_test's behavior.
-
- A related issue is that gdb_test doesn't enforce that if you specify
- QUESTION, that you also specify RESPONSE. I.e., you should pass 1, 2,
- 3, or 5 arguments to gdb_test, but never 4, or more than 5. Making
- gdb_test detect bogus arguments actually regressed some testcases,
- also all fixed in previous commits.

- gdb.base/skip.exp: Don't abuse gdb_test's question support

- # If that happens try to step a second time.
- gdb_test "step" "foo \\(\\) at.*" "step 3" \

-
- After a patch later in this series, gdb_test will FAIL if GDB does NOT
- issue the question, so this test would start failing on older GCCs.
-
- Switch to using gdb_test_multiple instead. There are three spots in

- Avoid having to unload file in gdb.server/connect-with-no-symbol-file.exp

- does:

-
- A following patch will make gdb_test expect the question out of GDB if

- gdb.base/scope.exp: Remove bogus gdb_test questions
- This test is abusing the QUESTION/RESPONSE feature to send an
- alternative command to GDB if the first command fails. Like so:
-
- gdb_test "print 'scope0.c'::filelocal" \
- "\\\$$decimal = 1" "print 'scope0.c'::filelocal at main" \
- "No symbol \"scope0.c\" in current context.*" \
- "print '$srcdir/$subdir/scope0.c'::filelocal"
-
- So if 'scope0.c' doesn't work, we try again with
- '$srcdir/$subdir/scope0.c'. I strongly suspect this is really an
- obsolete test. I think that if '$srcdir/$subdir/scope0.c' works, then
- 'scope0.c' should have worked too, thus I'd think that if we pass due
- to the question path, then it's a bug. So just remove the question
- part passed to gdb_test.

- gdbsupport/event-loop.cc: simplify !HAVE_POLL paths
- gdbsupport/event-loop.cc throughout handles the case of use_poll being
- true on a system where HAVE_POLL is not defined, by calling
- internal_error if that situation ever happens.
-
- Simplify this by moving the "use_poll" global itself under HAVE_POLL,
- so that it's way more unlikely to ever end up in such a situation.
- Then, move the code that checks the value of use_poll under HAVE_POLL
- too, and remove the internal_error calls. Like, from:
-
- if (use_poll)
- {
- #ifdef HAVE_POLL
- // poll code
- #else
- internal_error (....);
- #endif /* HAVE_POLL */
- }
- else
- {
- // select code
- }
-
- to
-
- #ifdef HAVE_POLL
- if (use_poll)
- {
- // poll code
- }
- else
- #endif /* HAVE_POLL */
- {
- // select code
- }
-
- While at it, make use_poll be a bool. The current code is using
- unsigned char most probably to save space, but I don't think it really
- matters here.

- Fix "gdb --write" with core files
- If you load a core file into GDB with the --write option, or "set
- write on" (equivalent), and then poke memory expecting it to patch the
- core binary, you'll notice something odd -- the write seems to
- succeed, but in reality, it doesn't. The value you wrote doesn't
- persist. Like so:
-
- $ gdb -q --write -c testsuite/outputs/gdb.base/patch/gcore.test
- [New LWP 615986]
- Core was generated by `/home/pedro/gdb/build/gdb/testsuite/outputs/gdb.base/patch/patch'.
- Program terminated with signal SIGTRAP, Trace/breakpoint trap.
- #0 0x0000555555555131 in ?? ()
- (gdb) p *(unsigned char *)0x0000555555555131 = 1
- $1 = 1 '\001'
- (gdb) p *(unsigned char *)0x0000555555555131
- $2 = 185 '\271'
- (gdb)
-
- Diffing hexdumps of before/after patching, reveals that a "0x1" was
- actually written somewhere in the file. The problem is that the "0x1"
- was written at the wrong offset in the file...
-
- That happens because _bfd_elf_set_section_contents does this to seek
- to the section's offset:
-
- pos = hdr->sh_offset + offset;
- if (bfd_seek (abfd, pos, SEEK_SET) != 0
- || bfd_bwrite (location, count, abfd) != count)
- return false;
-
- ... and 'hdr->sh_offset' is zero, so we seek to just OFFSET, which is
- incorrect. The reason 'hdr->sh_offset' is zero is that
- kernel-generated core files normally don't even have a section header
- table (gdb-generated ones do, but that's more an accident than a
- feature), and indeed elf_core_file_p doesn't even try to read sections
- at all:
-
- /* Core files are simply standard ELF formatted files that partition
- the file using the execution view of the file (program header table)
- rather than the linking view. In fact, there is no section header
- table in a core file.
-
- The process status information (including the contents of the general
- register set) and the floating point register set are stored in a
- segment of type PT_NOTE. We handcraft a couple of extra bfd sections
- that allow standard bfd access to the general registers (.reg) and the
- floating point registers (.reg2). */
-
- bfd_cleanup
- elf_core_file_p (bfd *abfd)
-
- Changing _bfd_elf_set_section_contents from:
-
- pos = hdr->sh_offset + offset;
-
- to:
-
- pos = section->filepos + offset;
-
- fixes it. If we do that however, the tail end of
- _bfd_elf_set_section_contents ends up as a copy of
- _bfd_generic_set_section_contents, so just call the latter, thus
- eliminating some duplicate code.
-
- New GDB testcase included, which exercises both patching an executable
- and patching a core file. Patching an executable already works
- without this fix, because in that case BFD reads in the sections
- table. Still, we had no testcase for that yet. In fact, we have no
- "set write on" testcases at all, this is the first one.
-
- Tested on x86-64 GNU/Linux, gdb, ld, binutils, and gas.

- [gdb/testsuite] Fix gdb.cp/break-f-std-string.cc with older gcc
- When running test-case gdb.cp/break-f-std-string.exp on openSUSE Leap 15.3
- with system gcc 7.5.0, I run into:
- ...
- (gdb) whatis /r std::string^M
- No symbol "string" in namespace "std".^M
- (gdb) FAIL: gdb.cp/break-f-std-string.exp: _GLIBCXX_USE_CXX11_ABI=1: \
- whatis /r std::string
- ...
- The same for gcc 8.2.1, but it passes with gcc 9.3.1.
-
- At source level (as we can observe in the .ii file with -save-temps) we have
- indeed:
- ...
- namespace std {
- namespace __cxx11 {
- typedef basic_string<char> string;
- }
- }
- ...
- while with gcc 9.3.1, we have instead:
- ...
- namespace std {
- namespace __cxx11 {
- ...
- }
- typedef basic_string<char> string;
- }
- ...
- due to gcc commit 33b43b0d8cd ("Define std::string and related typedefs
- outside __cxx11 namespace").
-
- Fix this by adding the missing typedef for gcc version 5 (the first version to
- have the dual abi) to 8 (the last version missing aforementioned gcc commit).
-
- Tested on x86_64-linux, with:
- - system gcc 7.5.0

-
- Make gdb.ada/float-bits.exp more generic
- There are assumptions in the test about the long double format
- being used. While the results are OK for i387 128-bit long doubles, it
- is not correct for IEEE quad 128-bit long doubles.
-
- Also, depending on the target (64-bit/32-bit), long doubles may not
- be available at all. And it may be the case that the compiler for a 64-bit
- target doesn't support 128-bit long doubles, but GDB might still support it
- internally.
-
- Lastly, not every long double format has invalid values. Some formats
- consider all values as valid floating point numbers.
-
- These divergences cause the following FAIL's on aarch64/arm:
-
- FAIL: gdb.ada/float-bits.exp: print val_long_double
- FAIL: gdb.ada/float-bits.exp: print val_long_double after assignment
-
- With the above in mind, extend the test a little so it behaves well on
- different architectures and so it works with different long double
- formats.
-
- Main changes:
-
- - Use long double values appropriate for the long double format.
- - Test long double assignment to compiler-generated long
- double variables.
- - Test long double assignment to GDB internal variables.
-
- Tested on x86_64 (16 PASS), i686 (16 PASS), aarch64 (12 PASS) and arm (9 PASS).

- (gdb) FAIL: gdb.dwarf2/dw2-out-of-range-end-of-seq.exp: runto: run to main
- ...
-
- There are two problems here:
- - the test-case contains a hardcoded "DW_LNS_advance_pc 1" which causes the
- breakpoint pointing in the middle of an insn
- - the FAIL triggers on aarch64-linux, but not on x86_64-linux, because the
- test-case uses 'main_label' as the address of the first and only valid entry
- in the line table, and:
- - on aarch64-linux, there's no prologue, so main_label and main coincide,
- while
- - on x86_64-linux, there's a prologue, so main_label is different from main.
-
- Fix these problems by:
- - eliminating the use of "DW_LNS_advance_pc 1", and using
- "DW_LNE_set_address $main_end" instead, and
- - eliminating the use of main_label, using "DW_LNE_set_address $main_start"
- instead.

- Fix "b f(std::string)" when current language is C
- If you try to set a breakpoint at a function such as "b
- f(std::string)", and the current language is C, the breakpoint fails
- to be set, like so:
-
- (gdb) set language c
- break f(std::string)
- Function "f(std::string)" not defined.
- Make breakpoint pending on future shared library load? (y or [n]) n
- (gdb)
-
- The problem is that the code in GDB that expands the std::string
- typedef hits this in c-typeprint.c:
-
- /* If we have "typedef struct foo {. . .} bar;" do we want to
- print it as "struct foo" or as "bar"? Pick the latter for
- C++, because C++ folk tend to expect things like "class5
- *foo" rather than "struct class5 *foo". We rather
- arbitrarily choose to make language_minimal work in a C-like
- way. */
- if (language == language_c || language == language_minimal)
- {
- if (type->code () == TYPE_CODE_UNION)
- gdb_printf (stream, "union ");
- else if (type->code () == TYPE_CODE_STRUCT)
- {
- if (type->is_declared_class ())
- gdb_printf (stream, "class ");
- else
- gdb_printf (stream, "struct ");
- }
- else if (type->code () == TYPE_CODE_ENUM)
- gdb_printf (stream, "enum ");
- }
-
- I.e., std::string is expanded to "class std::..." instead of just
- "std::...", and then the "f(class std::..." symbol doesn't exist.
-
- Fix this by making cp-support.c:inspect_type print the expanded
- typedef type using the language of the symbol whose type we're
- expanding the typedefs for -- in the example in question, the
- "std::string" typedef symbol, which is a C++ symbol.
-
- Use type_print_raw_options as it seems to me that in this scenario we
- always want raw types, to match the real symbol names.
-
- Adjust the gdb.cp/break-f-std-string.exp testcase to try setting a
- breakpoint at "f(std::string)" in both C and C++.

- Always pass an explicit language down to c_type_print
- The next patch will want to do language->print_type(type, ...), to
- print a type in a given language, avoiding a dependency on the current
- language. That doesn't work correctly currently, however, because
- most language implementations of language_defn::print_type call
- c_print_type without passing down the language. There are two
- overloads of c_print_type, one that takes a language, and one that
- does not. The one that does not uses the current language, defeating
- the point of calling language->print_type()...
-
- This commit removes the c_print_type overload that does not take a
- language, and adjusts the codebase throughout to always pass down a
- language. In most places, there's already an enum language handy.
- language_defn::print_type implementations naturally pass down
- this->la_language. In a couple spots, like in ada-typeprint.c and
- rust-lang.c there's no enum language handy, but the code is written
- for a specific language, so we just hardcode the language.
-
- In gnuv3_print_method_ptr, I wasn't sure whether we could hardcode C++
- here, and we don't have an enum language handy, so I made it use the
- current language, just like today. Can always be improved later.

- Fix "b f(std::string)", always use DMGL_VERBOSE

- This testcase was added back in 2011, here:
-
- [patch] Remove DMGL_VERBOSE
- https://sourceware.org/pipermail/gdb-patches/2011-June/083081.html
-
- Back then, the testcase would pass cleanly. It turns out that the
- reason it fails today is that the testcase is exercising something in
- GDB that only makes sense if the program is built for the pre-C++11
- libstc++ ABI. Back then the C++11 ABI didn't exist yet, but nowadays,
- you need to compile with -D_GLIBCXX_USE_CXX11_ABI=0 to use the old
- ABI. See "Dual ABI" in the libstdc++ manual, at
- <https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html>.
-
- If we tweak the gdb.cp/no-dmgl-verbose.exp testcase to force the old
- ABI with -D_GLIBCXX_USE_CXX11_ABI=0, then it passes cleanly.

- So why is it that setting a breakpoint at "f(std::string)" fails with
- modern ABI, but passes with old ABI?
-
- This is where libiberty demangler's DMGL_VERBOSE option comes in. The
- Itanium ABI mangling scheme has a shorthand form for std::string (and
- some other types). See
- <https://itanium-cxx-abi.github.io/cxx-abi/abi.html>:
-
- "In addition, the following catalog of abbreviations of the form "Sx" are used:
-
- <substitution> ::= St # ::std::
- <substitution> ::= Sa # ::std::allocator
- <substitution> ::= Sb # ::std::basic_string
- <substitution> ::= Ss # ::std::basic_string < char,
- ::std::char_traits<char>,
- ::std::allocator<char> >
- <substitution> ::= Si # ::std::basic_istream<char, std::char_traits<char> >
- <substitution> ::= So # ::std::basic_ostream<char, std::char_traits<char> >
- <substitution> ::= Sd # ::std::basic_iostream<char, std::char_traits<char> >
- "
-
- When the libiberty demangler encounters such a abbreviation, by
- default, it expands it to the user-friendly typedef "std::string",
- "std::iostream", etc.. If OTOH DMGL_VERBOSE is specified, the
- abbreviation is expanded to the underlying, non-typedefed fullname
- "std::basic_string<char, std::char_traits<char>, std::allocator<char> >"
- etc. as documented in the Itanium ABI, and pasted above. You can see
- the standard abbreviations/substitutions in
- libiberty/cp-demangle.c:standard_subs.
-
- Back before Jan's patch in 2011, there were parts of GDB that used
- DMGL_VERBOSE, and others that did not, leading to mismatches. The
- solution back then was to stop using DMGL_VERBOSE throughout.
-
- GDB has code in place to let users set a breakpoint at a function with
- typedefs in its parameters, like "b f(uint32_t)". Demangled function
- names as they appear in the symbol tables almost (more on this is in a
- bit) never have typedefs in them, so when processing "b f(uint32_t)"
- GDB first replaces "uint32_t" for its underlying type, and then sets a
- breakpoint on the resulting prototype, in this case "f(unsigned int)".
-
- Now, if DMGL_VERBOSE is _not_ used, then the demangler demangles the
- mangled name of a function such as "void f(std::string)" that was
- mangled using the standard abbreviations mentioned above really as:
-
- "void f(std::string)".
-
- For example, the mangled name of "void f(std::string)" if you compile
- with old pre-C++11 ABI is "_Z1fSs". That uses the abbreviation "Ss",
- so if you demangle that without DMGL_VERBOSE, you get:
-
- $ echo "_Z1fSs" | c++filt --no-verbose
- f(std::string)
-
- while with DMGL_VERBOSE you'd get:
-
- $ echo "_Z1fSs" | c++filt
- f(std::basic_string<char, std::char_traits<char>, std::allocator<char> >)
-
- If, when the user sets a breakpoint at "f(std::string)", GDB would
- replace the std::string typedef for its underlying type using the same
- mechanism I mentioned for the "f(uint32_t)" example above, then GDB
- would really try to set a breakpoint at "f(std::basic_string<char,
- std::char_traits<char>, std::allocator<char> >)", and that would fail,
- as the function symbol GDB knows about for that function, given no
- DMGL_VERBOSE, is "f(std::string)".
-
- For this reason, the code that expands typedefs in function parameter
- names has an exception for std::string (and other standard
- abbreviation types), such that "std::string" is never
- typedef-expanded.
-
- And here lies the problem when you try to do "b f(std::string)" with a
- program compiled with the C++11 ABI. In that case, std::string
- expands to a different underlying type, like so:
-
- f(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)
-
- and this symbol naturally mangles differently, as:
-
- _Z1fNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE
-
- and then because this doesn't use the shorthand mangling abbreviation
- for "std::string" anymore, it always demangles as:
-
- f(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)
-
- Now, when using the C++11 ABI, and you set a breakpoint at
- "f(std::string)", GDB's typedefs-in-parameters expansion code hits the
- exception for "std::string" and doesn't expand it, so the breakpoint
- fails to be inserted, because the symbol that exists is really the
-
- f(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)
-
- one, not "f(std::string)".
-
- So to fix things for C++11 ABI, clearly we need to remove the
- "std::string" exception from the typedef-in-parameters expansion
- logic. If we do just that, then "b f(std::string)" starts working
- with the C++11 ABI.
-
- However, if we do _just_ that, and nothing else, then we break
- pre-C++11 ABI...
-
- The solution is then to in addition switch GDB to always use
- DMGL_VERBOSE. If we do this, then pre-C++11 ABI symbols works the
- same as C++11 ABI symbols overall -- the demangler expands the
- standard abbreviation for "std::string" as "std::basic_string<char,
- std::char_traits<char>, std::allocator<char> >" and letting GDB expand
- the "std::string" typedef (etc.) too is no longer a problem.
-
- To avoid getting in the situation where some parts of GDB use
- DMGL_VERBOSE and others not, this patch adds wrappers around the
- demangler's entry points that GDB uses, and makes those force
- DMGL_VERBOSE.
-
- The point of the gdb.cp/no-dmgl-verbose.exp testcase was to try to
- ensure that DMGL_VERBOSE doesn't creep back in:
-
- gdb_test {break 'f(std::basic_string<char, std::char_traits<char>, std::allocator<char> >)'} \
- {Function ".*" not defined\.} \
- "DMGL_VERBOSE-demangled f(std::string) is not defined"
-
- This obviously no longer makes sense to have, since we now depend on
- DMGL_VERBOSE. So the patch replaces gdb.cp/no-dmgl-verbose.exp with a
- new gdb.cp/break-f-std-string.exp testcase whose purpose is to make
- sure that setting a breakpoint at "f(std::string)" works. It
- exercises both pre-C++11 ABI and C++11 ABI.

- gdb/testsuite: fix testsuite regressions for unix/-m32 board
- This commit fixes two regressions introduced by
- 891e4190ba705373eec7b374209478215fff5401.
-
- Reason for the failures was, that on a 32 bit machine the maximum
- array length as well as the maximum allocatable memory for arrays
- (in bytes) both seem to be limited by the maximum value of a 4
- byte (signed) Fortran integer. This lead to compiler errors/unexpected
- behavior when compiling/running the test with the -m32 board. This
- behavior is compiler dependent and can differ for different compiler
- implementations, but generally, it seemed like a good idea to simply
- avoid such situations.
-
- The affected tests check for GDB's overflow behavior when using KIND
- parameters with GDB implemented Fortran intrinsic functions. If these
- KIND parameters are too small to fit the actual intrinsic function's
- result, an overflow is expected. This was done for 1, 2, and 4
- byte overflows. The last one caused problems, as it tried to allocate
- arrays of length/byte-size bigger than the 4 byte signed integers which
- would then be used with the LBOUND/UBOUND/SIZE intrinsics.
-
- The tests were adapted to only execute the 4 byte overflow tests when
- running on targets with 64 bit. For this, the compiled tests evaluate the
- byte size of a C_NULL_PTR via C_SIZEOF, both defined in the ISO_C_BINDING
- module. The ISO_C_BINDING constant C_NULL_PTR is a Fortran 2003, the
- C_SIZEOF a Fortran 2008 extension. Both have been implemented in their
- respective compilers for while (e.g. C_SIZEOF is available since
- gfortran 4.6). If this byte size evaluates to less than 8 we skip the
- 4 byte overflow tests in the compiled tests of size.f90 and
- lbound-ubound.f90. Similarly, in the lbound-ubound.exp testsfile we skip
- the 4 byte overflow tests if the procedure is_64_target evaluates to false.
-
- In size.f90, additionally, the to-be-allocated amount of bytes did not
- fit into 4 byte signed integers for some of the arrays, as it was
- approximately 4 times the maximum size of a 4 byte signed integer. We
- adapted the dimensions of the arrays in question as the meaningfulness
- of the test does not suffer from this.
-
- With this patch both test run fine with the unix/-m32 board and
- gcc/gfortran (9.4) as well as the standard board file.
-
- We also thought about completely removing the affected test from the
- testsuite. We decided against this as the 32 bit identification comes
- with Fortran 2008 and removing tests would have decreased coverage.
-
- A last change that happened with this patch was due to gfortran's and
- ifx's type resolution when assigning big constants to Fortran Integer*8
- variables. Before the above changes this happened in a parameter
- statement. Here, both compilers happily accepted a line like
-
- integer*8, parameter :: var = 2147483647 + 5.
-
- After this change the assignment is not done as a parameter
- anymore, as this triggered compile time overflow errors. Instead,
- the assignment is done dynamically, depending on the kind of machine one
- is on. Sadly, just changing this line to
-
- integer*8 :: var
- var = 2147483647 + 5
-
- does not work with ifx (or flang for that matter, they behave similarly
- here). It will create an integer overflow in the addition as ifx deduces
- the type the additon is done in as Integer*4. So var will actually
- contain the value -2147483644 after this. The lines
-
- integer*8 :: var
- var = 2147483652
-
- on the other hand fail to compile with gfortran (9.4.0) as the compiler
- identifies an Integer overflow here. Finally, to make this work with
- all three compilers an additional parameter has been introduced
-
- integer*8, parameter :: helper = 2147483647
- integer*8 :: var
- var = helper + 5.
-
- This works on all 3 compilers as expected.

-
- enum class visit_state is defined inside the class template

- template parameters. This commit moves it out, so that only one such
- type exists. This reduces the size of a -O0 -g3 build for me by

- 163707424 gdb.fixed
-
- and codesize by some 0.5%.

- gdb/testsuite: fix occasional failure in gdb.mi/mi-multi-commands.exp
- In bug PR gdb/29036, another failure was reported for the test
- gdb.mi/mi-multi-commands.exp. This test sends two commands to GDB as
- a single write, and then checks that both commands are executed.
-
- The problem that was encountered here is that the output of the first
- command, which looks like this:
-
- ^done,value="\"FIRST COMMAND\""
-
- Is actually produced in parts, first the '^done' is printed, then the
- ',value="\"FIRST COMMAND\"" is printed.
-
- What was happening is that some characters from the second command
- were being echoed after the '^done' had been printed, but before the
- value part had been printed. To avoid this issue I've relaxed the
- pattern that checks for the first command a little. With this fix in
- place the occasional failure in this test is no longer showing up.

- gdb: fix for gdb.base/eof-exit.exp test failures
- This fix relates to PR gdb/29032, this makes the test more stable by
- ensuring that the Ctrl-D is only sent once the prompt has been
- displayed. This issue was also discussed on the mailing list here:
-
- https://sourceware.org/pipermail/gdb-patches/2022-April/187670.html
-
- The problem identified in the bug report is that sometimes the Ctrl-D
- (that the test sends to GDB) arrives while GDB is processing a
- command. When this happens the Ctrl-D is handled differently than if
- the Ctrl-D is sent while GDB is waiting for input at a prompt.
-
- The original intent of the test was that the Ctrl-D be sent while GDB
- was waiting at a prompt, and that is the case the occurs most often,
- but, when the Ctrl-D arrives during command processing, then GDB will
- ignore the Ctrl-D, and the test will fail.
-
- This commit ensures the Ctrl-D is always sent while GDB is waiting at
- a prompt, which makes this test stable.
-
- But, that still leaves an open question, what should happen when the
- Ctrl-D arrives while GDB is processing a command? This commit doesn't
- attempt to answer that question, which is while bug PR gdb/29032 will

- syscall pipe2, not syscall pipe), so enable the same for amd64, by:
- - adding amd64_sys_pipe2 in enum amd64_syscall
- - translating amd64_sys_pipe2 to gdb_sys_pipe2 in amd64_canonicalize_syscall
-
- Tested on x86_64-linux, specifically on:
- - openSUSE Tumbleweed (with glibc 2.35), and
- - openSUSE Leap 15.3 (with glibc 2.31).

- [gdb/testsuite] Fix gdb.tui/scroll.exp with read1
- When running test-case gdb.tui/scroll.exp, I get:
- ...
- Box Dump (80 x 8) @ (0, 0):
- 0 $17 = 16
- 1 (gdb) p 17
- 2 $18 = 17
- 3 (gdb) p 18

- 5 (gdb) p 19
- 6 $20 = 19
- 7 (gdb)
- PASS: gdb.tui/scroll.exp: check cmd window in flip layout

- but with check-read1 I get instead:
- ...
- Box Dump (80 x 8) @ (0, 0):

- 1 (gdb) p 16
- 2 $17 = 16
- 3 (gdb) p 17
- 4 $18 = 17
- 5 (gdb) p 18
- 6 $19 = 18
- 7 (gdb) p 19
- FAIL: gdb.tui/scroll.exp: check cmd window in flip layout
- ...
-
- The "p 19" command is handled by Term::command, which sends the command and then
- does Term::wait_for "^$gdb_prompt [string_to_regexp $cmd]", which:
- - matches the line with "(gdb) p 19", and
- - tries to match the following prompt "(gdb) "
-
- The problem is that scrolling results in reissuing output before the "(gdb) p
- 19", and the second matching triggers on that. Consequently, wait_for no
- longer translates gdb output into screen actions, and the screen does not
- reflect the result of "p 19".
-
- Fix this by using a new proc wait_for_region_contents, which in contrast to
- wait_for can handle a multi-line regexp.
-
- Tested on x86_64-linux with make targets check and check-read1.

- [gdb/testsuite] Fix gdb.cp/casts.exp with -m32

- (gdb) FAIL: gdb.cp/casts.exp: print (unsigned long long) &gd == gd_value

- print (unsigned long long) &gd == gd_value^M
- $34 = false^M
- (gdb) FAIL: gdb.cp/casts.exp: print (unsigned long long) &gd == gd_value
- ...
-
- The gd_value is set by this assignment:
- ...
- unsigned long long gd_value = (unsigned long long) &gd;
- ...
-
- The problem here is directly casting from a pointer to a non-pointer-sized
- integer.
-
- Fix this by adding an intermediate cast to std::uintptr_t.
-
- Tested on x86_64-linux with native and target board unix/-m32.

-
- The ERROR is a common problem, filed as

- - adding a "setup done" pass/fail to be turned into an unresolved
- in case of error during setup.

-
- commit 91395d97d905c31ac38513e4aaedecb3b25e818f
- Date: Tue Feb 15 17:28:03 2022 +0000
-
- gdb: handle bracketed-paste-mode and EOF correctly
-
- It was observed that, if a previous command is selected at the
- readline prompt using the up arrow key, then when the command is
- accepted (by pressing return) an unexpected 'quit' message will be
- printed by GDB. Here's an example session:
-
- (gdb) p 123
- $1 = 123
- (gdb) p 123
- quit
- $2 = 123
- (gdb)
-
- In this session the second 'p 123' was entered not by typing 'p 123',
- but by pressing the up arrow key to select the previous command. It
- is important that the up arrow key is used, typing Ctrl-p will not
- trigger the bug.
-
- The problem here appears to be readline's EOF detection when handling
- multi-character input sequences. I have raised this issue on the
- readline mailing list here:
-
- https://lists.gnu.org/archive/html/bug-readline/2022-04/msg00012.html
-
- a solution has been proposed here:
-
- https://lists.gnu.org/archive/html/bug-readline/2022-04/msg00016.html
-
- This patch includes a test for this issue as well as a back-port of
- (the important bits of) readline commit:
-
- commit 2ef9cec8c48ab1ae3a16b1874a49bd1f58eaaca1
- Date: Wed May 4 11:18:04 2022 -0400
-
- fix for setting RL_STATE_EOF in callback mode
-
- That commit also includes some updates to the readline documentation
- and tests that I have not included in this commit.
-
- With this commit in place the unexpected 'quit' messages are resolved.

- PowerPC fix for gdb.server/sysroot.exp
- On PowerPC, the stop in the printf function is of the form:
-
- Breakpoint 2, 0x00007ffff7c6ab08 in printf@@GLIBC_2.17 () from /lib64/libc.so.6
-
- On other architectures the output looks like:
-
- Breakpoint 2, 0x0000007fb7ea29ac in printf () from /lib/aarch64-linux-gnu/libc.so.6
-
- The following patch modifies the printf test by matchine any character
- starting immediately after the printf. The test now works for PowerPC
- output as well as the output from other architectures.
-
- The test has been run on a Power 10 system and and Intel x86_64 system.

- Add initializers to tracepoint
- This adds some initializers to tracepoint. I think right now these
- may not be needed, due to obscure rules about zero initialization.
- However, this will change in the next patch, and anyway it is clearer

-
- Remove init_raw_breakpoint_without_location
- This removes init_raw_breakpoint_without_location, replacing it with a
- constructor on 'breakpoint' itself. The subclasses and callers are
- all updated.
-
- Disable copying for breakpoint
- It seems to me that breakpoint should use DISABLE_COPY_AND_ASSIGN.
- This patch does this.
-

- Move works_in_software_mode to watchpoint
- works_in_software_mode is only useful for watchpoints. This patch
- moves it from breakpoint to watchpoint, and changes it to return bool.

- This changes breakpoint::explains_signal to return bool.
-
- Remove breakpoint::ops
- The breakpoint::ops field is set but never used. This removes it.
-

- This changes print_recreate_thread to be a method on breakpoint. This
- function is only used as a helper by print_recreate methods, so I

- PowerPC: bp-permanent.exp, kill-after-signal fix
- The break point after the stepi on Intel is the entry point of the user
- signal handler function test_signal_handler. The code at the break point
- looks like:
-
- 0x<hex address> <test_signal_handler>: endbr64
-
- On PowerPC with a Linux 5.9 kernel or latter, the address where gdb stops
- after the stepi is in the vdso code inserted by the kernel. The code at the
- breakpoint looks like:
-
- 0x<hex address> <__kernel_start_sigtramp_rt64>: bctrl
-
- This is different from other architectures. As discussed below, recent
- kernel changes involving the vdso for PowerPC have been made changes to the
- signal handler code flow. PowerPC is now stopping in function
- __kernel_start_sigtramp_rt64. PowerPC now requires an additional stepi to
- reach the user signal handler unlike other architectures.
-
- The bp-permanent.exp and kill-after-signal tests run fine on PowerPC with an
- kernel that is older than Linux 5.9.
-
- The PowerPC 64 signal handler was updated by the Linux kernel 5.9-rc1:
-
- commit id: 0138ba5783ae0dcc799ad401a1e8ac8333790df9
- powerpc/64/signal: Balance return predictor stack in signal trampoline
-
- An additional change to the PowerPC 64 signal handler was made in Linux
- kernel version 5.11-rc7 :
-
- commit id: 24321ac668e452a4942598533d267805f291fdc9
- powerpc/64/signal: Fix regression in __kernel_sigtramp_rt64() semantics
-
- The first kernel change, puts code into the user space signal handler (in
- the vdso) as a performance optimization to prevent the call/return stack
- from getting out of balance. The patch ensures that the entire
- user/kernel/vdso cycle is balanced with the addition of the "brctl"
- instruction.
-
- The second patch, fixes the semantics of __kernel_sigtramp_rt64(). A new
- symbol is introduced to serve as the jump target from the kernel to the
- trampoline which now consists of two parts.
-
- The above changes for PowerPC signal handler, causes gdb to stop in the
- kernel code not the user signal handler as expected. The kernel dispatches
- to the vdso code which in turn calls into the signal handler. PowerPC is
- special in that the kernel is using a vdso instruction (bctrl) to enter the
- signal handler.
-
- I do not have access to a system with the first patch but not the second. I did
- test on Power 9 with the Linux 5.15.0-27-generic kernel. Both tests fail on
- this Power 9 system. The two tests also fail on Power 10 with the Linux
- 5.14.0-70.9.1.el9_0.ppc64le kernel.
-
- The following patch fixes the issue by checking if gdb stopped at "signal
- handler called". If gdb stopped there, the tests verifies gdb is in the kernel
- function __kernel_start_sigtramp_rt64 then does an additional stepi to reach the
- user signal handler. With the patch below, the tests run without errors on both
- the Power 9 and Power 10 systems with out any failures.

- (gdb) FAIL: gdb.dwarf2/locexpr-data-member-location.exp: step into foo

-
- The problem is that the test-case tries to mimic some gdb_compile_shlib

- while gdb_compile_shlib properly filters out the -fno-PIE -no-pie.
-
- Consequently, the address for foo determined by get_func_info doesn't match

- Fix crash when creating index from index
- My patches yesterday to unify the DWARF index base classes had a bug
- -- namely, I did the wholesale dynamic_cast-to-static_cast too hastily
- and introduced a crash. This can be seen by trying to add an index to
- a file that has an index, or by running a test like gdb-index-cxx.exp
- using the cc-with-debug-names.exp target board.
-
- This patch fixes the crash by introducing a new virtual method and
- removing some of the static casts.

- This sequence of functions is invoked due to a series of conditions:
-
- 1 - The probe-based breakpoint mechanism failed (for some reason) so ...
-
- 2 - ... gdbserver has to know what type of architecture it is dealing
- with so it can pick the right breakpoint kind, so it wants to
- check if we have a 64-bit target.
-
- 3 - To determine the size of a register, we currently fetch the
- current thread's register cache, and the current thread pointer
- is now nullptr.
-
- In #3, the current thread is nullptr because gdb_read_memory clears it
- on purpose, via set_desired_process, exactly to expose code relying on
- the current thread when it shouldn't. It was always possible to end
- up in this situation (when the current thread exits), but it was
- harder to reproduce before.
-
- This commit fixes it by tweaking is_64bit_tdesc to look at the current
- process's tdesc instead of the current thread's tdesc.
-
- Note that the thread's tdesc is itself filled from the process's
- tdesc, so this should be equivalent:
-
- struct regcache *
- get_thread_regcache (struct thread_info *thread, int fetch)
- {
- struct regcache *regcache;
-
- regcache = thread_regcache_data (thread);
-
- ...
- if (regcache == NULL)
- {
- struct process_info *proc = get_thread_process (thread);
-
- gdb_assert (proc->tdesc != NULL);
-
- regcache = new_register_cache (proc->tdesc);
- set_thread_regcache_data (thread, regcache);
- }
- ...

- gdb/remote: send qSymbol to all inferiors on startup
- start_remote_1 calls remote_check_symbols after things are set up to
- give the remote side a chance to look up symbols. One call to
- remote_check_symbols sets the "general thread", if needed, and sends one
- qSymbol packet. However, a remote target could have more than one
- process on initial connection, and this would send a qSymbol for only
- one of these processes.

- Change it to iterate on all the target's inferiors and send a qSymbol
- packet for each one.

- gdb/remote: iterate on pspace inferiors in remote_new_objfile
- Commit 152a17495663 ("gdb: prune inferiors at end of
- fetch_inferior_event, fix intermittent failure of
- gdb.threads/fork-plus-threads.exp") broke some tests with the
- native-gdbserver board, such as:
-
- (gdb) PASS: gdb.base/step-over-syscall.exp: detach-on-fork=off: follow-fork=child: break cond on target : vfork: break marker
- continue^M
- Continuing.^M
- terminate called after throwing an instance of 'gdb_exception_error'^M
-
- I can manually reproduce the issue by running (just the commands that
- the test does as a one liner):
-
- $ ./gdb -q --data-directory=data-directory \
- testsuite/outputs/gdb.base/step-over-syscall/step-over-vfork \
- -ex "tar rem | ../gdbserver/gdbserver - testsuite/outputs/gdb.base/step-over-syscall/step-over-vfork" \
- -ex "b main" \
- -ex c \
- -ex "d 1" \
- -ex "set displaced-stepping off" \
- -ex "b *0x7ffff7d7ac5a if main == 0" \
- -ex "set detach-on-fork off" \
- -ex "set follow-fork-mode child" \
- -ex c \
- -ex "inferior 1" \
- -ex "b marker" \
- -ex c
-
- ... where 0x7ffff7d7ac5a is the exact address of the vfork syscall
- (which can be found by looking at gdb.log).
-
- The important part of the above is that a vfork syscall creates inferior
- 2, then inferior 2 executes until exit, then we switch back to inferior
- 1 and try to resume it.
-
- The uncaught exception happens here:
-

- terminate called after throwing an instance of 'gdb_exception_error'
-
- What happens is:
-
- - After doing the "continue" on inferior 1, the remote target gives us
- a VFORK_DONE event. The core ignores it and resumes inferior 1.
- - Since prune_inferiors is now called after each handled event, in
- fetch_inferior_event, it is called after we handled that VFORK_DONE
- event and resumed inferior 1.
- - Inferior 2 is pruned, which (see backtrace above) causes its program
- space to be deleted, which clears the symtabs for that program space,
- which calls the new_objfile observable and remote_new_objfile
- observer (with a nullptr objfile, to indicate that the previously
- loaded symbols have been discarded), which calls
- remote_check_symbols.
-
- remote_check_symbols is the function that sends the qSymbol packet, to
- let the remote side ask for symbol addresses. The problem is that the
- remote target is working in all-stop / sync mode and is currently
- resumed. It has sent a vCont packet to resume the target and is waiting
- for a stop reply. It can't send any packets in the mean time. That
- causes the exception to be thrown.
-
- This wasn't a problem before, when prune_inferiors was called in
- normal_stop, because it was always called at a time the target was not
- resumed.
-
- An important observation here is that the new_objfile observable is
- invoked for a change in inferior 2's program space (inferior 2's program
- space is the current program space). Inferior 2 isn't bound to any
- process on the remote side (it has exited, that's why it's being
- pruned). It doesn't make sense to try to send a qSymbol packet for a
- process that doesn't exist on the remote side. remote_check_symbols
- actually attempts to avoid that:
-
- /* The remote side has no concept of inferiors that aren't running
- yet, it only knows about running processes. If we're connected
- but our current inferior is not running, we should not invite the
- remote target to request symbol lookups related to its
- (unrelated) current process. */
- if (!target_has_execution ())
- return;
-
- The problem here is that while inferior 2's program space is the current
- program space, inferior 1 is the current inferior. So the check above
- passes, since inferior has execution. We therefore try to send a
- qSymbol packet for inferior 1 in reaction to a change in inferior 2's
- program space, that's wrong.
-
- This exposes a conceptual flaw in remote_new_objfile. The "new_objfile"
- event concerns a specific program space, which can concern multiple
- inferiors, as inferiors can share a program space. We shouldn't
- consider the current inferior at all, but instead all inferiors bound to
- the affected program space. Especially since the current inferior can
- be unrelated to the current program space at that point.
-
- To be clear, we are in this state because ~program_space sets itself as
- the current program space, but there is no more inferior having that
- program space to switch to, inferior 2 has already been unlinked.
-
- To fix this, make remote_new_objfile iterate on all inferiors bound to
- the affected program space. Remove the target_has_execution check from
- remote_check_symbols, replace it with an assert. All callers must
- ensure that the current inferior has execution before calling it.

- gdbserver: track current process as well as current thread
- The recent commit 421490af33bf ("gdbserver/linux: Access memory even
- if threads are running") caused a regression in
- gdb.threads/access-mem-running-thread-exit.exp with gdbserver, which I
- somehow missed. Like so:
-
- (gdb) print global_var
- Cannot access memory at address 0x555555558010
- (gdb) FAIL: gdb.threads/access-mem-running-thread-exit.exp: non-stop: access mem (print global_var after writing, inf=2, iter=1)
-
- The problem starts with GDB telling GDBserver to select a thread, via
- the Hg packet, which GDBserver complies with, then that thread exits,
- and GDB, without knowing the thread is gone, tries to write to memory,
- through the context of the previously selected Hg thread.
-
- GDBserver's GDB-facing memory access routines, gdb_read_memory and
- gdb_write_memory, call set_desired_thread to make GDBserver re-select
- the thread that GDB has selected with the Hg packet. Since the thread
- is gone, set_desired_thread returns false, and the memory access
- fails.
-
- Now, to access memory, it doesn't really matter which thread is
- selected. All we should need is the target process. Even if the
- thread that GDB previously selected is gone, and GDB does not yet know
- about that exit, it shouldn't matter, GDBserver should still know
- which process that thread belonged to.
-
- Fix this by making GDBserver track the current process separately,
- like GDB also does. Add a new set_desired_process routine that is
- similar to set_desired_thread, but just sets the current process,
- leaving the current thread as NULL. Use it in the GDB-facing memory
- read and write routines, to avoid failing if the selected thread is
- gone, but the process is still around.

- Fix gdb.threads/access-mem-running-thread-exit.exp w/ native-extended-gdbserver
- When testing gdb.threads/access-mem-running-thread-exit.exp with
- --target_board=native-extended-gdbserver, we get:
-
- Running gdb.threads/access-mem-running-thread-exit.exp ...
- FAIL: gdb.threads/access-mem-running-thread-exit.exp: non-stop: second inferior: runto: run to main
- WARNING: Timed out waiting for EOF in server after monitor exit
-
- === gdb Summary ===
-
- # of expected passes 3
- # of unexpected failures 1
- # of unsupported tests 1
-
- The problem is that the testcase spawns a second inferior with
- -no-connection, and then runto_main does "run", which fails like so:
-
- (gdb) run
- Don't know how to run. Try "help target".
- (gdb) FAIL: gdb.threads/access-mem-running-thread-exit.exp: non-stop: second inferior: runto: run to main
-
- That "run" above failed because native-extended-gdbserver forces "set
- auto-connect-native-target off", to prevent testcases from mistakenly
- running programs with the native target, which would exactly be the
- case here.
-
- Fix this by letting the second inferior share the first inferior's
- connection everywhere except on targets that do reload on run (e.g.,
- --target_board=native-gdbserver).

- gdb/testsuite: small cleanup in mi-break-qualified.exp
- It is not necessary to pass an empty string to mi_gdb_start, passing
- the empty string is equivalent to passing no arguments, which is what
- we do everywhere else (that we don't need to specify an actual
- argument).
-
- The only place we use 'mi_gdb_start ""' is in
- gdb.mi/mi-break-qualified.exp, so in this commit I just replace that
- with a call to 'mi_gdb_start' - just for consistency.
-
- There should be no change in what is tested after this commit.

- gdb/testsuite: change mi_gdb_start to take a list of flags
- After this previous commit I was thinking about the API of
- mi_gdb_start. I felt that the idea of passing flags as separate
- arguments and using 'args' to gather these into a list, though clever,
- was not an intuitive API.
-
- In this commit I modify mi_gdb_start so that it expects a single
- argument, which should be a list of flags. Thus, where we previously
- would have said:
-
- mi_gdb_start separate-mi-tty separate-inferior-tty
-
- We would now say:
-
- mi_gdb_start { separate-mi-tty separate-inferior-tty }
-
- However, it turns out we never actually call mi_gdb_start passing two
- arguments in this way at all. We do in some places do this:
-
- mi_gdb_start separate-inferior-tty
-
- But that's fine, a single string like this works equally well as a
- single item list, so this will not need updating.
-
- There is also one place where we do this:
-
- eval mi_gdb_start $start_ops
-
- where $start_ops is a list that might contains 0, 1, or 2 items. The
- eval here is used to expand the $start_ops list so mi_gdb_start sees
- the list contents as separate arguments. In this case we just need to
- drop the use of eval.
-
- I think that the new API is more intuitive, but others might
- disagree, in which case I can drop this change.
-
- There should be no change in what is tested after this commit.

- gdb/testsuite: fix mi-exec-run.exp with native-extended-gdbserver board
- When running with the native-extended-gdbserver board, I currently see
- one failure in gdb.mi/mi-exec-run.exp:
-
- FAIL: gdb.mi/mi-exec-run.exp: inferior-tty=separate: mi=separate: force-fail=0: breakpoint hit reported on console (timeout)
-
- In this test the MI interface should be started in a separate tty,
- which means we should have a CLI tty and an MI tty, however, this is
- not happening. Instead GDB is just started in MI mode and there is no
- CLI tty.
-
- The test script tries to switch between the CLI an MI terminals and
- look for some expected output on each, however, as there is no CLI
- terminal the expected output never arrives, and the test times out.
-
- It turns out that this is not a GDB problem, rather, this is an issue
- with argument passing within the test script.
-
- The proc default_mi_gdb_start expects to take a set of flags (strings)
- as arguments, each of flag is expected to be a separate argument. The
- default_mi_gdb_start proc collects all its arguments into a list using
- the special 'args' parameter name, and then iterates over this list to
- see which flags were passed.
-
- In mi_gdb_start, which forwards to default_mi_gdb_start, the arguments
- are also gathered into the 'args' parameter list, but are then
- expanded back to be separate arguments using the eval trick, i.e.:
-
- proc mi_gdb_start { args } {
- return [eval default_mi_gdb_start $args]
- }
-
- This ensures that when we arrive in default_mi_gdb_start each flag is
- a separate argument, rather than appearing as a single list containing
- all arguments.
-
- When using the native-extended-gdbserver board however, the file
- boards/native-extended-gdbserver.exp is loaded, and this file replaces
- the default mi_gdb_start with its own version.
-
- This new mi_gdb_start also gathers the arguments into an 'args' list,
- but forgets to expand the arguments out using the eval trick.
-
- As a result, when using the native-extended-gdbserver board, by the
- time we get to default_mi_gdb_start, we end up with the args list
- containing a single item, which is a list containing all the arguments
- the user passed.
-
- What this means is that if the user passes two arguments, then, in
- default_mi_gdb_start, instead of seeing two separate arguments, we see
- a single argument made by concatenating the two arguments together.
-
- The only place this is a problem is in the test mi-exec-run.exp,
- which (as far as I can see) is the only test where we might try to
- pass both arguments at the same time. Currently we think we passed
- both arguments to mi_gdb_start, but mi_gdb_start behaves as if no
- arguments were passed.
-
- This commit fixes the problem by making use of the eval trick within
- the native-extended-gdbserver version of mi_gdb_start. After this,
- the FAIL listed at the top of this message is resolved.

- gdb: fix failures in gdb.mi/mi-exec-run.exp with native-extended-gdbserver
- When running the gdb.mi/mi-exec-run.exp test using the
- native-extended-gdbserver I see failures like this:
-
- FAIL: gdb.mi/mi-exec-run.exp: inferior-tty=main: mi=main: force-fail=1: run failure detected
- FAIL: gdb.mi/mi-exec-run.exp: inferior-tty=main: mi=separate: force-fail=1: run failure detected
- FAIL: gdb.mi/mi-exec-run.exp: inferior-tty=separate: mi=separate: force-fail=1: run failure detected
-
- There's a race condition here, so you might see a slightly different
- set of failures, but I always see some from the 'run failure detected'
- test.
-
- NOTE: I also see an additional test failure:
-
- FAIL: gdb.mi/mi-exec-run.exp: inferior-tty=separate: mi=separate: force-fail=0: breakpoint hit reported on console (timeout)
-
- but that is a completely different issue, and is not being addressed
- in this commit.
-
- The problem for the 'run failure detected' test is that we end up
- in gdb_expect looking for output from two spawn-ids, one from
- gdbserver, and one from gdb. We're looking for one output pattern
- from each spawn-id, and for the test to pass we need to see both
- patterns.
-
- Now, if gdb exits then this is a test failure (this would indicate gdb
- crashing, which is bad), so we have an eof pattern associated with
- the gdb spawn-id.
-
- However, in this particular test we expect gdbserver to fail to
- execute the binary (the test binary is set non-executable), and so we
- get an error message from gdbserver (which matches the pattern), and
- then gdbserver exits, this is expected.
-
- The problem is that after spotting the pattern from gdbserver, we
- often see the eof from gdbserver before we see the pattern from gdb.
- If this happens then we drop out of the gdb_expect without ever seeing
- the pattern from gdb, and fail the test.
-
- In this commit, I place the spawn-id of gdbserver into a global
- variable, and then use this global variable as the -i option within
- the gdb_expect.
-
- Now, once we have seen the expected pattern on the gdbserver spawn-id,
- the global variable is cleared. After this the gdb_expect no longer
- checks the gdbserver spawn-id for additional output, and so never sees
- the eof event. This leaves the gdb_expect running, which allows the
- pattern from gdb to be seen, and for the test to pass.
-
- I now see no failures relating to 'run failure detected'.

-
- Add bp_static_marker_tracepoint
- Because the actual construction of a breakpoint is buried deep in

- De-duplicate .gdb_index
- This de-duplicates variables and types in .gdb_index, making the new
- index closer to what gdb generated before the new DWARF scanner
- series. Spot-checking the resulting index for gdb itself, it seems
- that the new scanner picks up some extra symbols not detected by the
- old one. I tested both the new and old versions of gdb on both new
- and old versions of the index, and startup time in all cases is
- roughly the same (it's worth noting that, for gdb itself, the index no
- longer provides any benefit over the DWARF scanner). So, I think this

- Fix .debug_names regression with new indexer
- At AdaCore, we run the internal gdb test suite in several modes,
- including one using the .debug_names index. This caught a regression
- caused by the new DWARF indexer.
-
- First, the psymtabs-based .debug_names generator was completely wrong.
- However, to avoid making the rewrite series even bigger (fixing the
- writer will also require rewriting the .debug_names reader), it
- attempted to preserve the weirdness.
-
- However, this was not done properly. For example the old writer did
- this:
-
- - case STRUCT_DOMAIN:
- - return DW_TAG_structure_type;
-
- The new code, instead, simply preserves the actual DWARF tag -- but
- this makes future lookups fail, because the .debug_names reader only
- looks for DW_TAG_structure_type.
-
- This patch attempts to revert to the old behavior in the writer.

- After handling the EXITED event for inferior 2, inferior 2 should have
- stayed the current inferior, which should have prevented it from getting
- pruned. When debugging, we find that when getting at the
- prune_inferiors call, the current inferior is inferior 1. Further
- debugging shows that prior to the call to
- clean_up_just_stopped_threads_fsms, the current inferior is inferior 2,
- and after, it's inferior 1. Then, back in fetch_inferior_event, the
- restore_thread object is disabled, due to:
-
- /* If we got a TARGET_WAITKIND_NO_RESUMED event, then the
- previously selected thread is gone. We have two
- choices - switch to no thread selected, or restore the
- previously selected thread (now exited). We chose the
- later, just because that's what GDB used to do. After
- this, "info threads" says "The current thread <Thread
- ID 2> has terminated." instead of "No thread
- selected.". */
- if (!non_stop
- && cmd_done
- && ecs->ws.kind () != TARGET_WAITKIND_NO_RESUMED)
- restore_thread.dont_restore ();
-
- So in the end, inferior 1 stays current, and inferior 2 gets wrongfully
- pruned.
-
- I'd say clean_up_just_stopped_threads_fsms is the culprit here. It
- actually attempts to restore the event_thread to be current at the end,
- after the loop (I presume the current thread on entry is always supposed
- to be the event thread). But in this case, the event is of kind EXITED,
- and ecs->event_thread is not set, so the current inferior isn't
- restored.
-
- Fix that by using scoped_restore_current_thread. If there is no current
- thread, scoped_restore_current_thread will still restore the current
- inferior, and that's what we want.
-
- Random note: the thread_info object for inferior 2's thread is never
- freed. It is held (by refcount) by the restore_thread object in
- fetch_inferior_event, while the inferior's thread list gets cleared, in
- the exit event processing. When the refcount reaches 0 (when the
- restore_thread object is destroyed), there's nothing that actually
- deletes the thread_info object. And I think that nothing in GDB points
- to it anymore, so it leaks. I don't want to fix that in this patch, but
- thought it would be good to mention it, in case somebody has an idea for
- how to fix that.

- Slightly tweak and clarify target_resume's interface
- The current target_resume interface is a bit odd & non-intuitive.
- I've found myself explaining it a couple times the recent past, while
- reviewing patches that assumed STEP/SIGNAL always applied to the
- passed in PTID. It goes like this today:
-
- - if the passed in PTID is a thread, then the step/signal request is
- for that thread.
-
- - otherwise, if PTID is a wildcard (all threads or all threads of
- process), the step/signal request is for inferior_ptid, and PTID
- indicates which set of threads run free.
-
- Because GDB always switches the current thread to "leader" thread
- being resumed/stepped/signalled, we can simplify this a bit to:
-
- - step/signal are always for inferior_ptid.
-
- - PTID indicates the set of threads that run free.
-
- Still not ideal, but it's a minimal change and at least there are no
- special cases this way.
-
- That's what this patch does. It renames the PTID parameter to
- SCOPE_PTID, adds some assertions to target_resume, and tweaks
- target_resume's description. In addition, it also renames PTID to
- SCOPE_PTID in the remote and linux-nat targets, and simplifies their
- implementation a little bit. Other targets could do the same, but
- they don't have to.

- gdb: fix nullptr dereference in block::ranges()
- This commit:
-
- commit f5cb8afdd297dd68273d98a10fbfd350dff918d8
- Date: Sun Feb 6 22:27:53 2022 -0500
-
- gdb: remove BLOCK_RANGES macro
-
- introduces a potential nullptr dereference in block::ranges, this is
- breaking most tests, e.g. gdb.base/break.exp is failing for me.
-
- In the above patch BLOCK_CONTIGUOUS_P is changed from this:
-
- #define BLOCK_CONTIGUOUS_P(bl) (BLOCK_RANGES (bl) == nullptr \
- || BLOCK_NRANGES (bl) <= 1)
-
- to this:
-
- #define BLOCK_CONTIGUOUS_P(bl) ((bl)->ranges ().size () == 0 \
- || (bl)->ranges ().size () == 1)
-
- So, before the commit we checked for the block ranges being nullptr,
- but afterwards we just call block::ranges() in all cases.
-
- The problem is that block::ranges() looks like this:
-
- /* Return a view on this block's ranges. */
- gdb::array_view<blockrange> ranges ()
- { return gdb::make_array_view (m_ranges->range, m_ranges->nranges); }
-
- where m_ranges is:
-
- struct blockranges *m_ranges;
-
- And so, we see that the nullptr check has been lost, and we might end
- up dereferencing a nullptr.
-
- My proposed fix is to move the nullptr check into block::ranges, and
- return an explicit empty array_view if m_ranges is nullptr.
-
- After this, everything seems fine again.

- libctf: impose an ordering on conflicting types
- When two types conflict and they are not types which can have forwards
- (say, two arrays of different sizes with the same name in two different
- TUs) the CTF deduplicator uses a popularity contest to decide what to
- do: the type cited by the most other types ends up put into the shared
- dict, while the others are relegated to per-CU child dicts.
-
- This works well as long as one type *is* most popular -- but what if
- there is a tie? If several types have the same popularity count,
- we end up picking the first we run across and promoting it, and
- unfortunately since we are working over a dynhash in essentially
- arbitrary order, this means we promote a random one. So multiple
- runs of ld with the same inputs can produce different outputs!
- All the outputs are valid, but this is still undesirable.
-
- Adjust things to use the same strategy used to sort types on the output:
- when there is a tie, always put the type that appears in a CU that
- appeared earlier on the link line (and if there is somehow still a tie,
- which should be impossible, pick the type with the lowest type ID).
-
- Add a testcase -- and since this emerged when trying out extern arrays,
- check that those work as well (this requires a newer GCC, but since all
- GCCs that can emit CTF at all are unreleased this is probably OK as
- well).
-
- Fix up one testcase that has slight type ordering changes as a result
- of this change.

-
- Make gdb.base/parse_number.exp test all architectures
- There are some subtle differences between architectures, like the size
- of a "long" type, and this isn't currently accounted for in
- gdb.base/parse_number.exp.
-
- For example, on aarch64 a long type is 8 bytes, whereas a long type is
- 4 bytes for x86_64. This causes the following FAIL's:
-
- FAIL: gdb.base/parse_number.exp: lang=asm: ptype 0xffffffffffffffff
- FAIL: gdb.base/parse_number.exp: lang=auto: ptype 0xffffffffffffffff
- FAIL: gdb.base/parse_number.exp: lang=c: ptype 0xffffffffffffffff
- FAIL: gdb.base/parse_number.exp: lang=c++: ptype 0xffffffffffffffff
- FAIL: gdb.base/parse_number.exp: lang=fortran: p/x 0xffffffffffffffff
- FAIL: gdb.base/parse_number.exp: lang=fortran: ptype 0xffffffffffffffff
- FAIL: gdb.base/parse_number.exp: lang=go: ptype 0xffffffffffffffff
- FAIL: gdb.base/parse_number.exp: lang=local: ptype 0xffffffffffffffff
- FAIL: gdb.base/parse_number.exp: lang=minimal: ptype 0xffffffffffffffff
- FAIL: gdb.base/parse_number.exp: lang=objective-c: ptype 0xffffffffffffffff
- FAIL: gdb.base/parse_number.exp: lang=opencl: ptype 0xffffffffffffffff
- FAIL: gdb.base/parse_number.exp: lang=pascal: ptype 0xffffffffffffffff
-
- There are some fortran-specific divergences as well, where 32-bit
- architectures show "unsigned int" for both 32-bit and 64-bit integers
- and 64-bit architectures show "unsigned int" and "unsigned long" for
- 32-bit and 64-bit integers.
-
- There might be a bug that 32-bit fortran truncates 64-bit values to
- 32-bit, given "p/x 0xffffffffffffffff" returns "0xffffffff".
-
- Here's what we get for aarch64:
-
- (gdb) ptype 0xffffffff
- type = unsigned int
- (gdb) ptype 0xffffffffffffffff
- type = unsigned long
- (gdb) p sizeof (0xffffffff)
- $1 = 4
- (gdb) p sizeof (0xffffffffffffffff)
- quit
- $2 = 8
- (gdb) ptype 0xffffffff
- type = unsigned int
- (gdb) ptype 0xffffffffffffffff
- type = unsigned long
-
- And for arm:
-
- (gdb) ptype 0xffffffff
- type = unsigned int
- (gdb) ptype 0xffffffffffffffff
- quit
- type = unsigned long long
- (gdb) p sizeof (0xffffffff)
- quit
- $1 = 4
- (gdb) p sizeof (0xffffffffffffffff)
- quit
- $2 = 8
- (gdb) ptype 0xffffffff
- type = unsigned int
- (gdb) ptype 0xffffffffffffffff
- type = unsigned long
-
- This patch...
-
- * Makes the testcase iterate over all architectures, thus covering all
- the different combinations of types/sizes every time.
-
- * Adjusts the expected values and types based on the sizes of long
- long, long and int.
-
- A particularly curious architecture is s12z, which has 32-bit long
- long, and thus no way to represent 64-bit integers in C-like
- languages.

- gdb/arm: Extend arm_m_addr_is_magic to support FNC_RETURN, add unwind-secure-frames command
- This patch makes use of the support for several stack pointers
- introduced by the previous patch to switch between them as needed
- during unwinding.
-
- It introduces a new 'unwind-secure-frames' arm command to enable/disable
- mode switching during unwinding. It is enabled by default.
-
- It has been tested using an STM32L5 board (with cortex-m33) and the
- sample applications shipped with the STM32Cube development
- environment: GTZC_TZSC_MPCBB_TrustZone in
- STM32CubeL5/Projects/NUCLEO-L552ZE-Q/Examples/GTZC.
-
- The test consisted in setting breakpoints in various places and check
- that the backtrace is correct: SecureFault_Callback (Non-secure mode),
- __gnu_cmse_nonsecure_call (before and after the vpush instruction),
- SecureFault_Handler (Secure mode).
-
- This implies that we tested only some parts of this patch (only MSP*
- were used), but remaining parts seem reasonable.

- The second test case tests several of the ISA 3.01 instructions. Specifically,

- Change how "print/x" displays floating-point value
-
- Currently, "print/x" will display a floating-point value by first
- casting it to an integer type. This yields weird results like:

- (gdb) print/x 1.5
- $1 = 0x1
- ...
- Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=16242

- The above change results in 417 regression test failures since the expected
- Power vector register output no longer match.
-
- This patch updates the expected Altivec floating point register prints to
- the hexadecimal format for both big endian and little endian systems. The

- gdb/infrun: assert !step_over_info_valid_p in restart_threads
- While working in gdb/infrun.c:restart_threads, I was wondering what are
- the preconditions to call the function. It seems to me that
- !step_over_info_valid_p should be a precondition (i.e. if we are doing
- an inline step over breakpoint, we do not want to resume non stepping
- threads as one of them might miss the breakpoint which is temporally
- disabled).
-
- To convince myself that this is true, I have added an assertion to
- enforce this, and got one regression in the testsuite:
-
- FAIL: gdb.base/step-over-syscall.exp: vfork: displaced=off: single step over vfork (GDB internal error)
-
- This call to restart_threads originates from handle_vfork_done which
- does not check if a step over is active when restarting other threads:
-
- if (target_is_non_stop_p ())
- {
- scoped_restore_current_thread restore_thread;
-
- insert_breakpoints ();
- restart_threads (event_thread, event_thread->inf);
- start_step_over ();
- }
-
- In this patch, I propose to:
- - Call start_step_over before restart_threads. If a step over is already
- in progress (as it is the case in the failing testcase),
- start_step_over return immediately, and there is no point in restarting
- all threads just to stop them right away for a step over breakpoint.
- - Only call restart_threads if no step over is in progress at this
- point.
-
- In this patch, I also propose to keep the assertion in restart_threads
- to help enforce this precondition, and state it explicitly.
-
- I have also checked all other places which call restart_threads, and
- they all seem to check that there is no step over currently active
- before doing the call.
-
- As for infrun-related things, I am never completely sure I did not miss
- something. So as usual, all feedback and thoughts are very welcome.
-
- Tested on x86_64-linux-gnu.

- This commit does two things, first moving the setbuf calls out of

- setbuf so often.
-
- Then, for MS-Windows hosts, we don't call setbuf for terminals, this

- (gdb) FAIL: gdb.multi/multi-re-run.exp: re_run_inf=1: iter=1: runto: run to all_started
-
- The test does:
-
- - Connect to a remote target with inferior 2, continue and stop on the
- all_started function
- - Connect to a separate remote target / GDBserver instance with inferior 1,
- continue and (expect to) stop on the all_started function
-
- The failure seen above happens when trying to continue inferior 1.
-
- What happens is:
-
- - GDB tells inferior 1's remote target to continue
- - We go into fetch_inferior_event, try to get an event at random from
- the targets
- - do_target_wait happens to pick inferior 2's target
- - That target return TARGET_WAITKIND_NO_RESUMED, which makes sense:
- inferior 2 is stopped, that target has no resumed thread
- - handle_no_resumed tries to update the thread list of all targets:
-
- for (auto *target : all_non_exited_process_targets ())
- {
- switch_to_target_no_thread (target);
- update_thread_list ();
- }
-
- - When trying to update the thread list of inferior 1's target, it hits
- the "Cannot execute this command while the target is running" error.
- This target is working in "remote all-stop" mode, and it is currently
- waiting for a stop reply, so it can't send packets to update the
- thread list at this time.
-
- To handle the problem described in the comment in handle_no_resumed, I
- don't think it is necessary to update the thread list of all targets,
- but only the event target. That comment describes a kind of race
- condition where some target reports a breakpoint hit for a thread and
- then its last remaining resumed thread exits, so sends a "no resumed"
- event. If we ended up resuming the thread that hit a breakpoint, we
- want to ignore the "no resumed" and carry on.
-
- But I don't really see why we need to update the thread list on the
- other targets. I can't really articulate this, it's more a gut feeling,
- maybe I just fail to imagine the situation where this is needed. But
- here is the patch anyway, so we can discuss it. The patch changes
- handle_no_resumed to only update the thread list of the event target.
- This fixes the test run shown above.
-
- The way I originally tried to fix this was to make
- remote_target::update_thread_list return early if the target is
- currently awaiting a stop reply, since there's no way it can update the
- thread list at that time. But that felt more like papering over the
- problem. I then thought that we probably shouldn't be asking the target
- to update the thread list unnecessarily.

- Those objects are deleted by linux_process_target::mourn, but that is
- not called if we fail to attach, we only call remove_process. I
- initially fixed this by making linux_process_target::attach call
- linux_process_target::mourn on failure (before calling error). But this
- isn't done anywhere else (including in GDB) so it would just be
- confusing to do things differently here.
-
- Instead, add a linux_process_target::remove_linux_process helper method
- (which calls remove_process), and call that instead of remove_process in
- the Linux target. Move the free-ing of the extra data from the mourn
- method to that new method.

- gdb: handle bracketed-paste-mode and EOF correctly
- This commit replaces an earlier commit that worked around the issues
- reported in bug PR gdb/28833.
-
- The previous commit just implemented a work around in order to avoid
- the worst results of the bug, but was not a complete solution. The
- full solution was considered too risky to merge close to branching GDB
- 12. This improved fix has been applied after GDB 12 branched. See
- this thread for more details:
-
- https://sourceware.org/pipermail/gdb-patches/2022-March/186391.html
-
- This commit replaces this earlier commit:
-
- commit 74a159a420d4b466cc81061c16d444568e36740c
- Date: Fri Mar 11 14:44:03 2022 +0000
-
- gdb: work around prompt corruption caused by bracketed-paste-mode
-
- Please read that commit for a full description of the bug, and why is
- occurs.
-
- In this commit I extend GDB to use readline's rl_deprep_term_function
- hook to call a new function gdb_rl_deprep_term_function. From this
- new function we can now print the 'quit' message, this replaces the
- old printing of 'quit' in command_line_handler. Of course, we only
- print 'quit' in gdb_rl_deprep_term_function when we are handling EOF,
- but thanks to the previous commit (to readline) we now know when this
- is.
-
- There are two aspects of this commit that are worth further
- discussion, the first is in the new gdb_rl_deprep_term_function
- function. In here I have used a scoped_restore_tmpl to disable the
- readline global variable rl_eof_found.
-
- The reason for this is that, in rl_deprep_terminal, readline will
- print an extra '\n' character before printing the escape sequence to
- leave bracketed paste mode. You might then think that in the
- gdb_rl_deprep_term_function function, we could simply print "quit" and
- rely on rl_deprep_terminal to print the trailing '\n'. However,
- rl_deprep_terminal only prints the '\n' when bracketed paste mode is
- on. If the user has turned this feature off, no '\n' is printed.
- This means that in gdb_rl_deprep_term_function we need to print
- "quit" when bracketed paste mode is on, and "quit\n" when bracketed
- paste mode is off.
-
- We could absolutely do that, no problem, but given we know how
- rl_deprep_terminal is implemented, it's easier (I think) to just
- temporarily clear rl_eof_found, this prevents the '\n' being printed
- from rl_deprep_terminal, and so in gdb_rl_deprep_term_function, we can
- now always print "quit\n" and this works for all cases.
-
- The second issue that should be discussed is backwards compatibility
- with older versions of readline. GDB can be built against the system
- readline, which might be older than the version contained within GDB's
- tree. If this is the case then the system readline might not contain
- the fixes needed to support correctly printing the 'quit' string.
-
- To handle this situation I have retained the existing code in
- command_line_handler for printing 'quit', however, this code is only
- used now if the version of readline we are using doesn't not include
- the required fixes. And so, if a user is using an older version of
- readline, and they have bracketed paste mode on, then they will see
- the 'quit' sting printed on the line below the prompt, like this:
-
- (gdb)
- quit
-
- I think this is the best we can do when someone builds GDB against an
- older version of readline.
-
- Using a newer version of readline, or the patched version of readline
- that is in-tree, will now give a result like this in all cases:
-
- (gdb) quit
-
- Which is what we want.

-
- https://lists.gnu.org/archive/html/bug-readline/2022-02/msg00021.html
-
- The above commit is not yet in any official readline release, but my
- hope is that now it has been merged into the readline tree it should
- be safe enough to back port this fix to GDB's tree.
-
- At some point in the future we will inevitably want to roll forward
- the version of readline that we maintain in the binutils-gdb
- repository. When that day comes the changes in this commit can be
- replaced with the latest upstream readline code, as I have not changed
- the meaning of this code at all from what is in upstream readline.
-
- This commit alone does not fix the PR cli/28833 issue, for that see
- the next commit, which changes GDB itself.

- gdb: improved EOF handling when using readline 7
- In this commit:
-
- commit a6b413d24ccc5d76179bab866834e11fd6fec294
- Date: Fri Mar 11 14:44:03 2022 +0000
-
- gdb: work around prompt corruption caused by bracketed-paste-mode
-
- a change was made to GDB to work around bug PR gdb/28833. The
- consequence of this work around is that, when bracketed paste mode is
- enabled in readline, and GDB is quit by sending EOF, then the output
- will look like this:
-
- (gdb)
- quit
-
- The ideal output, which is what we get when bracketed paste mode is
- off, is this:
-
- (gdb) quit
-
- The reason we need to make this change is explained in the original
- commit referenced above. What isn't mentioned in the above commit, is
- that the change that motivated this work around was only added in
- readline 8, older versions of readline don't require the change.
-
- In later commits in this series I will add a fix to GDB's in-tree copy
- of readline (this fix is back-ported from upstream readline), and then
- I will change GDB so that, when using the (patched) in-tree readline,
- we can have the ideal output in all cases.
-
- However, GDB can be built against the system readline. When this is
- done, and the system readline is version 8, then we will still have to
- use the work around (two line) style output.
-
- But, if GDB is built against the system readline, and the system
- readline is an older version 7 readline, then there's no reason why we
- can't have the ideal output, after all, readline 7 doesn't include the
- change that we need to work around.
-
- This commit changes GDB so that, when using readline 7 we get the
- ideal output in all cases. This change is trivial (a simple check
- against the readline version number) so I think this should be fine to
- include.
-
- For testing this commit, you need to configure GDB including the
- '--with-system-readline' flag, and build GDB on a system that uses
- readline 7, for example 'Ubuntu 18.04'. Then run the test
- 'gdb.base/eof-exit.exp', you should expect everything to PASS.

- This test sometimes fail like this:
-
- info threads^M
- Id Target Id Frame ^M
- 11.12 process 2270719 Couldn't get registers: No such process.^M
- (gdb) FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: no threads left

- (gdb) FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: only inferior 1 left (the program exited)
-
- I can get it to fail quite reliably by pinning it to a core:
-
- $ taskset -c 5 make check TESTS="gdb.threads/fork-plus-threads.exp"
-
- The previous attempt at fixing this was:
-
- https://sourceware.org/pipermail/gdb-patches/2021-October/182846.html
-
- What we see is part due to a possible unfortunate ordering of events
- given by the kernel, and what could be considered a bug in GDB.
-
- The test program makes a number of forks, waits them all, then exits.
- Most of the time, GDB will get and process the exit event for inferior 1
- after the exit events of all the children. But this is not guaranteed.
- After the last child exits and is waited by the parent, the parent can
- exit quickly, such that GDB collects from the kernel the exit events for
- the parent and that child at the same time. It then chooses one event
- at random, which can be the event for the parent. This will result in
- the parent appearing to exit before its child. There's not much we can
- do about it, so I think we have to adjust the test to cope.
-
- After expect has seen the "exited normally" notification for inferior 1,
- it immediately does an "info thread" that it expects to come back empty.
- But at this point, GDB might not have processed inferior 11's (the last
- child) exit event, so it will look like there is still a thread. Of
- course that thread is dead, we just don't know it yet. But that makes
- the "no thread" test fail. If the test waited just a bit more for the
- "exited normally" notification for inferior 11, then the list of threads
- would be empty.
-
- So, first change, make the test collect all the "exited normally"
- notifications for all inferiors before proceeding, that should ensure we
- see an empty thread list. That would fix the first FAIL above.
-
- However, we would still have the second FAIL, as we expect inferior 11
- to not be there, it should have been deleted automatically. Inferior 11
- is normally deleted when prune_inferiors is called. That is called by
- normal_stop, which is only called by fetch_inferior_event only if the
- event thread completed an execution command FSM (thread_fsm). But the
- FSM for the continue command completed when inferior 1 exited. At that
- point inferior 11 was not prunable, as it still had a thread. When
- inferior 11 exits, prune_inferiors is not called.
-
- I think that can be considered a GDB bug. From the user point of view,
- there's no reason why in one case inferior 11 would be deleted and not
- in the other case.
-
- This patch makes the somewhat naive change to call prune_inferiors in
- fetch_inferior_event, so that it is called in this case. It is placed
- at this particular point in the function so that it is called after the
- user inferior / thread selection is restored. If it was called before
- that, inferior 11 wouldn't be pruned, because it would still be the
- current inferior.

- More const use and alloca avoidance in coff-pe-read.c
- This changes another function in coff-pe-read.c to use 'const' more,

- Use std::string in coff-pe-read.c
- coff-pe-read.c uses xsnprintf and alloca, but using std::string is

-
- Remove a const-removing cast from coff-pe-read.c

-
- Simplify BFD section iteration in coff-pe-read.c
- coff-pe-read.c iterates over BFD sections using bfd_map_over_sections,

- Fix for gdb.base/solib-search.exp test.
- The variable right_lib_flags is not being set correctly to define RIGHT.
- The value RIGHT is needed to force the address of the library functions
- lib1_func3 and lib2_func4 to occur at different address in the wrong and
- right libraries.
-
- With RIGHT defined correctly, functions lib1_func3 and lib2_func4 occur
- at different addresses the test runs correctly on Powerpc.
-
- The test needs the lib2 addresses to be different in the right and
- wrong cases. That is the point of introducing function lib2_spacer
- with the ifdef RIGHT compiler directive.
-
- On Intel, the ARRAY_SIZE of 1 versus 8192 is sufficient to get the
- dynamic linker to move the addresses of the library. You can also get
- the same effect on PowerPC but you must use a value much larger than
- 8192.
-
- The key thing is that the test was not properly setting RIGHT to
- defined to get the lib2_spacer function on Intel and Powerpc.
-
- Without the patch, we have the Intel backtrace for the bad libraries:
-
- backtrace
- #0 break_here () at /home/ ... /gdb/testsuite/gdb.base/solib-search.c:30

- Backtrace stopped: previous frame inner to this frame (corrupt stack?)
- (gdb) PASS: gdb.base/solib-search.exp: backtrace (with wrong libs) (data collection)
-
- The backtrace on Intel with the good libraries is:
-
- backtrace
- #0 break_here () at /.../binutils-gdb/gdb/testsuite/gdb.base/solib-search.c:30
- #1 0x00007ffff7fae156 in lib2_func4 () at /.../binutils-gdb/gdb/testsuite/gdb.base/solib-search-lib2.c:49
- #2 0x00007ffff7fbb156 in lib1_func3 () at /.../gdb.base/solib-search-lib1.c:49

- #4 0x00007ffff7fbb146 in lib1_func1 () at /.../gdb.base/solib-search-lib1.c:30
- #5 0x0000555555555156 in main () at /...solib-search.c:23
- (gdb) PASS: gdb.base/solib-search.exp: backtrace (with right libs) (data collection)
- PASS: gdb.base/solib-search.exp: backtrace (with right libs)
-
- In one case the backtrace is correct and the other it
- is wrong on Intel. This is due to the fact that the ARRAY_SIZE caused
- the dynamic linker to move the library function addresses around. I
- believe it has to do with the default size of the data and code
- sections used by the dynamic linker.
-
- So without the patch the backtrace on PowerPC looks like:
-
- backtrace
- #0 break_here () at /.../solib-search.c:30
- #1 0x00007ffff7f007f4 in lib2_func4 () at /.../solib-search-lib2.c:49
- #2 0x00007ffff7f307f4 in lib1_func3 () at /.../solib-search-lib1.c:49
- #3 0x00007ffff7f007ac in lib2_func2 () at /.../solib-search-lib2.c:30
- #4 0x00007ffff7f307ac in lib1_func1 () at /.../solib-search-lib1.c:30
- #5 0x000000001000074c in main () at /.../solib-search.c:23
-
- for both the good and bad libraries.

- The patch fixes defining RIGHT in solib-search-lib1.c and solib-search-
- lib2.c. Note, without the patch the lib1_spacer and lib2_spacer
- functions do not show up in the object dump of the Intel or Powerpc
- libraries as it should. The patch fixes that by making sure RIGHT gets
- defined.
-
- Now with the patch the backtrace for the bad library on PowerPC looks
- like:
-
- backtrace
- #0 break_here () at /.../solib-search.c:30
- #1 0x00007ffff7f0083c in __glink_PLTresolve () from /.../solib-search-lib2.so
- Backtrace stopped: frame did not save the PC
-
- And the backtrace for the good libraries on PowerPC looks like:
-
- backtrace
- #0 break_here () at /.../solib-search.c:30
- #1 0x00007ffff7f0083c in lib2_func4 () at /.../solib-search-lib2.c:49
- #2 0x00007ffff7f3083c in lib1_func3 () at /.../solib-search-lib1.c:49
- #3 0x00007ffff7f007cc in lib2_func2 () at /.../solib-search-lib2.c:30
- #4 0x00007ffff7f307cc in lib1_func1 () at /.../solib-search-lib1.c:30
- #5 0x000000001000074c in main () at /.../solib-search.c:23
- (gdb) PASS: gdb.base/solib-search.exp: backtrace (with right libs) (data collection)
- PASS: gdb.base/solib-search.exp: backtrace (with right libs)
-
- The issue then is on Power where the ARRAY_SIZE of 1 versus 8192 is not
- sufficient to cause the dymanic linker to allocate the libraries at
- different addresses. I don't claim to understand the specifics of how
- the dynamic linker works and what the default size is for the data and
- code sections are. My guess is by default PowerPC allocates a larger
- data size by default, which is large enough to hold array[8192]. The
- default size of the data section allocated by the dynamic linker on
- Intel is not large enough to hold array[8192] thus causing the code
- section on Intel to have to move when the large array is defined.
-
- Note on PowerPC, if you make ARRAY_SIZE big enough, then you will cause
- the library addresses to occur at different addresses as the larger
- data section forces the code section to a different address. That was
- actually my original fix for the program until I spoke with Doug Evans
- who originally wrote the test. Doug noticed that RIGHT was not getting
- defined as he originally intended in the test.
-
- With the patch to fix the definition of RIGHT, PowerPC has a bad and a
- good backtrace because the address of lib1_func3 and lib2_func4 both
- move because lib1_spacer and lib2_spacer are now defined
- before lib1_func3 and lib2_func4.
-
- Without the patch, the lib1_spacer and lib2_spacer function doesn't show
- up in the binary for the correct or incorrect library on Intel or PowerPC.
- With the patch, RIGHT gets defined as originally intended for the test on
- both architectures and lib1_spacer and lib2_spacer function show up in the
- binaries on both architectures changing the other function addresses as
- intended thus causing the test work as intended on PowerPC.

- gdb/testsuite: fix "set temporary breakpoint" DUPLICATEs
- Commit c67f4e538 ("gdb/testsuite: make gdb.ada/mi_prot.exp stop at
- expected location") introduced some DUPLICATEs in MI tests using
- mi_continue_to_line, for example:
-
- DUPLICATE: gdb.ada/mi_ref_changeable.exp: mi_continue_to_line: set temporary breakpoint
-
- These test names were previously differentiated by the location passed
- to mi_continue_to_line. Since the location can contain a path, that
- commit removed the location from the test name, in favor of a hardcoded
- string "set temporary breakpoint", hence removing the differentiator.
-
- mi_continue_to_line receives a "test" parameter, containing a test
- name. Add a "with_test_prefix" with that name, so that all tests
- recorded during mi_continue_to_line have this in their name.
-
- mi_continue_to_line passes that "test" string to mi_get_stop_line, that
- is a bit superfluous. mi_get_stop_line only uses that string in case of
- failures (it doesn't record a pass if everything goes fine). Since it's
- not crucial, just remove it, and adjust all callers.
-
- Adjust three gdb.mi/mi-var-*.exp tests to use prefixes to differentiate
- the multiple calls to mi_run_inline_test (which calls
- mi_continue_to_line).

-
- Always use dwarf2_initialize_objfile
- Internally we noticed that some tests would fail like so on Windows:
-
- warning: Section .debug_aranges in [...] has duplicate debug_info_offset 0x0, ignoring .debug_aranges.
-
- Debugging showed that, in fact, a second CU was being created at this
- offset. We tracked this down to the fact that, while the ELF reader
- is careful to re-use the per-BFD data, other readers are not, and
- could re-read the DWARF data multiple times.
-
- However, since the change to allow an objfile to have multiple "quick
- symbol" implementations, there's no reason for this approach -- it's
- safe and easy for all symbol readers to reuse the per-BFD data when
- reading DWARF.
-
- This patch implements this idea, simplifying dwarf2_build_psymtabs and
- making it private, and then switching to dwarf2_initialize_objfile as
- the sole way to start the DWARF reader.
-
- Note that, while I think the call to dwarf2_build_frame_info in
- machoread.c is also obsolete, I haven't attempted to remove it here.

- gdb: fix 'remote show FOO-packet' aliases
- The following behaviour was observed in GDB:
-
- (gdb) show remote X-packet
- Support for the `p' packet is auto-detected, currently unknown.
-
- Note the message mentions the 'p' packet. This is a regression since
- this commit:
-
- commit 8579fd136a614985bd27f20539c7bb7c5a51287d
- Date: Mon Nov 8 14:58:46 2021 +0000
-
- gdb/gdbsupport: make xstrprintf and xstrvprintf return a unique_ptr
-
- Before this commit the behaviour was:
-
- (gdb) show remote X-packet
- Support for the `X' packet is auto-detected, currently unknown.
-
- The problem was caused by a failed attempt to ensure that some
- allocated strings were deleted when GDB exits. The code in the above
- commit attempted to make use of 'static' to solve this problem,
- however, the solution was just wrong.
-
- In this new commit I instead allocate a static vector into which all
- the allocated strings are stored, this ensures the strings are
- released when GDB exits (which makes output from tools like valgrind
- cleaner), but each string within the vector can be unique, which fixes
- the regression.

- gdbsupport: add path_join function
- In this review [1], Eli pointed out that we should be careful when
- concatenating file names to avoid duplicated slashes. On Windows, a
- double slash at the beginning of a file path has a special meaning. So
- naively concatenating "/" and "foo/bar" would give "//foo/bar", which
- would not give the desired results. We already have a few spots doing:
-
- if (first_path ends with a slash)
- path = first_path + second_path
- else
- path = first_path + slash + second_path
-
- In general, I think it's nice to avoid superfluous slashes in file
- paths, since they might end up visible to the user and look a bit
- unprofessional.
-
- Introduce the path_join function that can be used to join multiple path
- components together (along with unit tests).
-
- I initially wanted to make it possible to join two absolute paths, to
- support the use case of prepending a sysroot path to a target file path,
- or the prepending the debug-file-directory to a target file path. But
- the code in solib_find_1 shows that it is more complex than this anyway
- (for example, when the right hand side is a Windows path with a drive
- letter). So I don't think we need to support that case in path_join.
- That also keeps the implementation simpler.
-
- Change a few spots to use path_join to show how it can be used. I
- believe that all the spots I changed are guarded by some checks that
- ensure the right hand side operand is not an absolute path.
-
- Regression-tested on Ubuntu 18.04. Built-tested on Windows, and I also
- ran the new unit-test there.

- The gdb_test_multiple pattern for the "notice empty URL" test in

- Fix it by using -re -wrap.

- gdb/testsuite: Introduce and use gdb_spawn_attach_cmdline
- Following a7e6a19e87f3d719ea23c65b580a6d9bca4ccab3 "gdb: testsuite: add
- new gdb_attach to check "attach" command", this commit proposes to
- introduce the gdb_spawn_attach_cmdline helper and use it in
- gdb.base/attach.exp.
-
- This helper starts GDB and adds the "--pid=$PID" argument.
-
- Also note that both the original and new implementation use
- gdb_spawn_with_cmdline_opts, which in the end uses default_gdb_spawn.
- This makes sure that we use $INTERNAL_GDBFLAGS, which by default already
- contain "-iex \"set height 0\" -iex \"set width 0\"". To avoid
- repetition of those arguments, gdb_spawn_attach_cmdline does not repeat
- those arguments.
-
- To maintain a behavior similat to what gdb.base/attach.exp used to do,
- gdb_spawn_attach_cmdline keeps the -quiet flag.

- Replace symbol_symtab with symbol::symtab
- This turns symbol_symtab into a method on symbol. It also replaces
- symbol_set_symtab with a method.
-
- Replace symbol_arch with symbol::arch
- This turns symbol_arch into a method on symbol.
-
- Replace symbol_objfile with symbol::objfile
- This turns symbol_objfile into a method on symbol.
-
- Remove symbol::aclass_index
- Symbols have an aclass_index method, but this isn't needed, because
- the aclass index isn't useful outside of the symbol implementation.
-
- Use array_view for symbol_impls
- It seemed to me that using array_view for symbol_impls would give a
- bit more error checking, at least when gdb is built in libstdc++ debug
- mode.
-
- Add accessors for symbol's artificial field
- For a series I'm experimenting with, it was handy to hide a symbol's
- "artificial" field behind accessors. This patch is the result.
-
- Unify the DWARF index holders
- The dwarf2_per_bfd object has a separate field for each possible kind
- of index. Until an earlier patch in this series, two of these were
- even derived from a common base class, but still had separate slots.
- This patch unifies all the index fields using the common base class
- that was introduced earlier in this series. This makes it more
- obvious that only a single index can be active at a time, and also
- removes some code from dwarf2_initialize_objfile.
-
- Add an ad hoc version check to dwarf_scanner_base
- Some generic code in the DWARF reader has a special case for older
- versions of .gdb_index. This patch adds an ad hoc version check
- method so that these spots can work without specific knowledge of
- which index is in use.
-
- Simplify version check in dw2_symtab_iter_next
- This simplifies the index versio check in dw2_symtab_iter_next, by
- passing a reference to the index object to this function. This avoids
- an indirection via the per_bfd object.
-
- Introduce and use dwarf_scanner_base
- This introduces dwarf_scanner_base, a base class for all the index
- readers in the DWARF code. Then, it changes both mapped_index_base
- and cooked_index_vector to derive from this new base class.
-
- Introduce readnow_functions
- This introduces readnow_functions, a new subclass of
- dwarf2_base_index_functions, and changes the DWARF reader to use it.
- This lets us drop the "index is NULL" hack from the gdb index code.
-
- Remove some "OBJF_READNOW" code from dwarf2_debug_names_index
- The dwarf2_debug_names_index code treats a NULL debug_names_table as
- if it were from OBJF_READNOW. However, this trick is only done for
- gdb_index, never for debug_names -- see dwarf2_initialize_objfile.
-
- Let mapped index classes create the quick_symbol_functions object
- This changes the mapped index classes to create the
- quick_symbol_functions objects. This is a step toward having a more
- abstract interface to mapped indices.
-
- Give mapped_index_base a virtual destructor
- This changes mapped_index_base to have a virtual destructor, so it can
- be destroyed via its base class.
-
- Move mapped_index_base to new header file
- This moves mapped_index_base and the helper struct name_component to a
- new header file in gdb/dwarf2/.

- gdb/selftest-arch: Make register_test_foreach_arch generate arch tests lazily
- The register_test_foreach_arch is used to instantiate a given selftest
- for all architectures supported by GDB. It is used in many _initialize_*
- functions (under initialize_all_files, called by gdb_init).
-
- Because the call is done during GDB's initialization, and because there
- is no guaranty about the order in which all the _initialize_* functions
- are executed, when register_test_foreach_arch is called, GDB is not
- fully initialized. Specifically, when a particular initialize function
- is executed, only the architectures registered at that point are listed
- by gdbarch_printable_names.
-
- As a consequence, the list of selftest effectively executed depends on
- the order the _initialize_* functions are called. This can be observed
- with the following:
-
- $ ./gdb/gdb \
- -data-directory ./gdb/data-directory \
- -quiet -batch -ex "maint selftest" 2>&1 \
- | grep -E "Ran [0-9]+ unit tests"
- Ran 145 unit tests, 0 failed
- $ GDB_REVERSE_INIT_FUNCTIONS=1 ./gdb/gdb \
- -data-directory ./gdb/data-directory \
- -quiet -batch -ex "maint selftest" 2>&1 \
- | grep -E "Ran [0-9]+ unit tests"
- Ran 82 unit tests, 0 failed
-
- To fix this, make register_test_foreach_arch register a lazy selftest
- generator. This way when the test generator is eventually executed, all
- architectures are registered and we do not have a dependency on the
- order the initialize functions are executed in.
-
- Tested on x86_64-linux

- gdbsupport/selftest: Allow lazy registration
- This patch adds a way to delay the registration of tests until the

- to be fully initialized in order to decide if a particular selftest can
- be executed or not.
-
- This mechanism will be used in the next patch.

- x86: don't mistake ordinary immediates for SAE / rounding control
- The way SAE templates are constructed was always puzzling me (including
- the need for separate templates in the first place), and expressing the
- extzra attribute via Imm8 actually has a bad effect: Ordinary immediates
- would also be accepted, leading to an extra byte being added after the
- instruction (i.e. generating bad code). Before re-working this (in
- particular to accept proper Intel syntax there), fix the immediate issue
- by adding the so far missing check.
-
- x86: VCMPSH is Evex.LLIG
- These were mistakenly flagged as Evex.128. Getting the LLIG status right
- for insns allowing for SAE is a prereq for planned further work.
-
- x86: drop stray CheckRegSize from VFPCLASSPH
- Like VFPCLASSP{S,D} it has only a single operand allowing multiple
- sizes, hence there are no pairs of operands to check for consistent
- size.
-
- x86/Intel: test non-legacy VCVT{,U}SI2SH insn forms
- For an unclear reason corresponding AVX512F tests were apparently not
- cloned or used as reference here, and instead the bogus legacy forms of
- the insns (with the embedded rounding specifier not last) were used.

- x86: correct and simplify NOP disassembly
- It's not just REX.W which is ignored with opcode 0x90. The same goes for
- REX.R and REX.X as well as empty REX. None of these are forms of
- "xchg %eax,%eax" (which would mean zero-extending %eax to %rax), so they
- also shouldn't be disassembled this way.
-
- While there simplify things: A single hook function suffices, thus
- making it unnecessary to keep two expressions in sync. And checking
- ins->address_mode for mode_64bit also is unnecessary, as "rex" can be
- non-zero only in that case anyway.

- gdb/testsuite/dwarf: don't automatically add directory and file entry for DWARF 5
- To support DWARF 5 in the DWARF assembler line tables, we currently copy
- the first user-provided directory and the first user-provided files and
- make them elements at indices 0 in the directory and file name tables.
- That was a sufficient behavior at the time (see commit 44fda089397a
- ("[gdb/testsuite] Support .debug_line v5 in dwarf assembler")), but in
- the following patches, I would need to have finer grained control on
- what is generated exactly. For example, I'd like to generate a DWARF 5 line
- table with just a single file and a single directory.
-
- Get rid of this behavior, and implement what is suggested in
- 44fda089397a: make include_dir return the directory index that can be
- used to refer to that directory entry (based on the DWARF version), and
- use it afterwards.
-
- Adjust dw2-lines.exp and dw2-prologue-end.exp accordingly. Their produced
- DWARF5 binaries will change a bit, in that they will now have a single
- directory and file, where they had two before. But it doesn't change
- the expected GDB behavior.

- gdb/testsuite: make gdb.ada/mi_prot.exp stop at expected location
- This test attempts to run until the line marked "STOP", which is at

-
- ... we see that the breakpoint is placed in some generated file, not in
- the test source file as we expect. The problem is that "b main" in Ada
- does not place a breakpoint on the "Ada main", but on some symbol in a
- generated source file. So when stopped at the "main" symbol, we are not
- stopped in the file that contains the STOP marker at line 34.
-
- The test passes anyway today, so it doesn't seem to matter that we are
- stopped at an unexpected location. But it starts failing with this
- patch [1], because b~prot.adb:34 happens to be between two functions, so
- the breakpoint doesn't resolve.
-
- Fix this by placing the breakpoint at "$srcfile:$line", which works
- regardless of what is the current source file.
-
- However, this ends up introducing a path in the test name. Modify
- mi_tbreak and mi_continue_to_line to avoid that.

- gdbserver/linux: Access memory even if threads are running
- Similarly to how the native Linux target was changed

-
- 05c06f318fd9 Linux: Access memory even if threads are running
- 8a89ddbda2ec Avoid /proc/pid/mem races (PR 28065)
-
- ... teach GDBserver to access memory even when the current thread is
- running, by always accessing memory via /proc/PID/mem.
-
- The existing comment:
-
- /* Neither ptrace nor /proc/PID/mem allow accessing memory through a
- running LWP. */
-
- ... is incorrect for /proc/PID/mem does allow that.
-
- Actually, from GDB's perspective, GDBserver could already access
- memory while threads were running, but at the expense of pausing all
- threads for the duration of the memory access, via
- prepare_to_access_memory. This new implementation does not require
- pausing any thread, thus
- linux_process_target::prepare_to_access_memory /
- linux_process_target::done_accessing_memory become nops. A subsequent
- patch will remove the whole prepare_to_access_memory infrastructure
- completely.
-
- The GDBserver linux-low.cc implementation is simpler than GDB's
- linux-nat.c's, because GDBserver always adds the unfollowed vfork/fork
- children to the process list immediately when the fork/vfork event is
- seen out of ptrace. I.e., there's no need to keep the file descriptor
- stored on a side map, we can store it directly in the process
- structure.

- gdbserver: special case target_write_memory len==0
- The next patch in this series adds a common helper routine for both
- memory reads and writes, like this:
-
- static int
- proc_xfer_memory (CORE_ADDR memaddr, unsigned char *readbuf,
- const gdb_byte *writebuf, int len)
- {
- gdb_assert ((readbuf == nullptr) != (writebuf == nullptr));
- ...
- }

- int
- linux_process_target::read_memory (CORE_ADDR memaddr,
- unsigned char *myaddr, int len)
- {
- return proc_xfer_memory (memaddr, myaddr, nullptr, len);
- }
-
- linux_process_target::write_memory (CORE_ADDR memaddr,
- const unsigned char *myaddr, int len)
- {
- return proc_xfer_memory (memaddr, nullptr, myaddr, len);
- }
-
- Surprisingly, the assertion fails. That happens because it can happen
- that target_write_memory is called with LEN==0, due to this in
- gdb/remote.c:
-

- In this scenario, in gdbserver's target_write_memory, the "myaddr"

- This commit adds an early return to target_write_memory to avoid

- same on the read side, in read_inferior_memory.

- gdbserver/qXfer::threads, prepare_to_access_memory=>target_pause_all
- handle_qxfer_threads_proper needs to pause all threads even if the
- target can read memory when threads are running, so use
- target_pause_all instead, which is what the Linux implementation of
- prepare_to_access_memory uses. (Only Linux implements this hook.)
-
- A following patch will make the Linux backend be able to access memory
- when threads are running, and thus will also make
- prepare_to_access_memory do nothing, which would cause testsuite
- regressions without this change.

- Ignore 0,0 entries in .debug_aranges
- When running the internal AdaCore test suite against the new DWARF
- indexer, I found one regression on RISC-V. The test in question uses
- --gc-sections, and winds up with an entry in the middle of a
- .debug_aranges that has both address and length of 0. In this
- scenario, gdb assumes the entries are terminated and then proceeds to
- reject the section because it reads a subsequent entry as if it were a
- header.
-
- It seems to me that, because each header describes the size of each
- .debug_aranges CU, it's better to simply ignore 0,0 entries and simply
- read to the end. That is what this patch does.
-
- I've patched an existing test to provide a regression test for this.

- Set the worker thread name on Windows

- is available.
-
- This is part of PR win32/29050.
-
- This patch isn't likely to be useful to many people in the short term,

- Implement thread_name for gdbserver
- This changes gdbserver to implement thread_name method.
-
- Share handle_ms_vc_exception with gdbserver
- Currently, gdb's native Windows target implements the exception-based
- approach for setting thread names, but gdbserver does not. This patch
- moves handle_ms_vc_exception to the shared nat/windows-nat.c code, as
- preparation for adding this support to gdbserver.
-
- Move target_read_string to target/target.c
- This moves the two overloads of target_read_string to a new file,
- target/target.c, and updates both gdb and gdbserver to build this.
-
- Remove the byte order parameter to target_read_string
- target_read_string takes a byte order parameter, but only uses this to
- check whether a given character is zero. This is readily done without
- requiring the parameter, so remove it.
-
- Rename read_string
- This renames read_string to be an overload of target_read_string.
- This makes it more consistent for the eventual merger with gdbserver.
-
- Don't call QUIT in read_string
- read_string does not need to call QUIT, because target_read_memory
- already does. This change is needed to make string-reading usable by
- gdbserver.

- Fix possible Cygwin build problem
- I noticed that nat/windows-nat.c checks __USEWIDE, but nothing sets it

- gdb/testsuite: Fix race in gdb.dwarf2/calling-convention.exp
- Pedro Alves warned me that there is a race in
- gdb.dwarf2/calling-convention.exp making the test sometimes fail on his
- setup. This can be reliably reproduced using :
-
- make check-read1 TESTS="gdb.dwarf2/calling-convention.exp"
-
- The relevant part of the gdb.log file is:
-
- return 35
- Function 'foo' does not follow the target calling convention.
- If you continue, setting the return value will probably lead to unpredictable behaviors.
- Make foo return now? (y or n) PASS: gdb.dwarf2/calling-convention.exp: return 35
- n
- Not confirmed
- (gdb) FAIL: gdb.dwarf2/calling-convention.exp: finish
-
- The issue is that when doing the test for "return 35", the DejaGnu test
- sends "n" (to tell GDB not to perform the return action) but never
- consumes the "Not confirmed" acknowledgment sent by GDB. Later, when
- trying to do the next test, DejaGnu tries to match the leftover output
- from the "return" test. As this output is not expected, the test fails.
-
- Fix by using gdb_test to send the "n" answer and match the confirmation
- and consume all output to the prompt.
-
- Also do minor adjustments to the main regex:
- - Remove the leading ".*" which is not required.
- - Ensure that the "?" from the question is properly escaped.
-
- Tested on x86_64-gnu-linux, using
-

- Fix regression on Windows with WOW64
- Internally at AdaCore, we recently started testing a 64-bit gdb
- debugging 32-bit processes. This failed with gdb head, but not with
- gdb 11.
-
- The tests fail like this:
-
- Starting program: [...].exe
- warning: Could not load shared library symbols for WOW64_IMAGE_SECTION.

- warning: Could not load shared library symbols for NOT_AN_IMAGE.
- Do you need "set solib-search-path" or "set sysroot"?
-
- After some debugging and bisecting, to my surprise the bug was
- introduced by commit 183be222 ("gdb, gdbserver: make target_waitstatus
- safe").
-
- The problem occurs in handle_exception. Previously the code did:
-
- - ourstatus->kind = TARGET_WAITKIND_STOPPED;
- [...]
- case EXCEPTION_BREAKPOINT:
- [...]
- - ourstatus->kind = TARGET_WAITKIND_SPURIOUS;
- [...]
- /* FALLTHROUGH */
- case STATUS_WX86_BREAKPOINT:
- DEBUG_EXCEPTION_SIMPLE ("EXCEPTION_BREAKPOINT");
- - ourstatus->value.sig = GDB_SIGNAL_TRAP;
- [...]
- - last_sig = ourstatus->value.sig;
-
- However, in the new code, the fallthrough case does:
-
- + ourstatus->set_stopped (GDB_SIGNAL_TRAP);
-
- ... which changes the 'kind' in 'ourstatus' after falling through.
-
- This patch rearranges the 'last_sig' setting to more closely match
- what was done before (this is probably not strictly needed but also
- seemed harmless), and removes the fall-through in the
- 'ignore_first_breakpoint' case when __x86_64__ is defined.

- gdb: change subfile::line_vector to an std::vector
- Change this field to an std::vector to facilitate memory management.
- Since the linetable_entry array is copied into the symtab resulting from
- the subfile, it is possible to change it without changing how symtab
- stores the linetable entries (which would be a much larger change).
-
- There is a small change in buildsym_compunit::record_line to avoid
- accessing a now invalid linetable_entry. Before this patch, we keep a
- pointer to the last linetable entry, pop it from the vector, and then
- read last->line. It works with the manually-maintained array, but since
- we now use std::vector::pop_back, I am afraid that it could be flagged
- as an invalid access by the various static / dynamic analysis tools to
- access the linetable_entry object after popping it from the vector.
- Instead, record just the line number in an optional and use it.
-
- There are substantial changes in xcoffread.c that simplify the code, but
- I can't test them. I was hesitant to do this change because of that,
- but I decided to send it anyway. I don't think that an almost dead
- platform should hold back improving the code in the common parts of GDB.
-
- The changes in xcoffread.c are:
-
- - Make arrange_linetable "arrange" the linetable passed as a parameter,
- instead of returning possibly a new one, possibly the same one.
- - In the "Process main file's line numbers.", I'm not too sure what
- happens. We get the lintable from "main_subfile", "arrange" it, but
- then assign the result to the current subfile, obtained with
- get_current_subfile. I assume that the current subfile is also the
- main one, so now I just call arrange_linetable on the main subfile's
- line table.
- - Remove that weird "Useless if!!!" FIXME comment. It's been there
- forever, but the "if" is still there, so I guess the "if" can stay
- there.

-
- This is because result_of_t has been introduced in C++14. Use the
- equivalent result_of<...>::type instead.
-
- result_of and result_of_t have been removed in C++20 though, so I think
- we'll need some patches eventually to make the code use invoke_result
- instead, depending on the C++ version.

-
- Remove dwarf2_per_cu_data::v
- Now that the psymtab reader has been removed, the
- dwarf2_per_cu_data::v union is no longer needed. Instead, we can
- simply move the members from dwarf2_per_cu_quick_data into
- dwarf2_per_cu_data and remove the "quick" object entirely.
-
- Delete DWARF psymtab code
- This removes the DWARF psymtab reader.

-
- Enable the new DWARF indexer
- This patch finally enables the new indexer. It is left until this
- point in the series to avoid any regressions; in particular, it has to
- come after the changes to the DWARF index writer to avoid this
- problem.
-
- However, if you experiment with the series, this patch can be moved
- anywhere from the patch to wire in the new reader to this point.
- Moving this patch around is how I got separate numbers for the
- parallelization and background finalization patches.
-
- In the ongoing performance example, this reduces the time from the
- baseline of 1.598869 to 0.903534.

- using the maps generated by the new indexer.
-
- Note that the new addrmap_index_data::using_index field will be

-
- Change parameters to write_address_map
- To support the removal of partial symtabs from the DWARF index writer,
- this makes a small change to have write_address_map accept the address
- map as a parameter, rather than assuming it always comes from the
- per-BFD object.
-
- Change the key type in psym_index_map
- In order to change the DWARF index writer to avoid partial symtabs,
- this patch changes the key type in psym_index_map (and renames that
- type as well). Using the dwarf2_per_cu_data as the key makes it
- simpler to reuse this code with the new indexer.
-
- Rename write_psymtabs_to_index
- We'll be removing all the psymtab code from the DWARF reader. As a
- preparatory step, this renames write_psymtabs_to_index to avoid the
- "psymtab" name.

-2022-04-12 Tom Tromey <tom@tromey.com>
-
- "Finalize" the DWARF index in the background
- After scanning the CUs, the DWARF indexer merges all the data into a
- single vector, canonicalizing C++ names as it proceeds. While not
- necessarily single-threaded, this process is currently done in just
- one thread, to keep memory costs lower.
-
- However, this work is all done without reference to any data outside
- of the indexes. This patch improves the apparent performance of GDB
- by moving it to the background. All uses of the index are then made
- to wait for this process to complete.
-
- In our ongoing example, this reduces the scanning time on gdb itself
- to 0.173937 (wall). Recall that before this patch, the time was
- 0.668923; and psymbol reader does this in 1.598869. That is, at the
- end of this series, we see about a 10x speedup.
-
-2022-04-12 Tom Tromey <tom@tromey.com>
-
- Parallelize DWARF indexing
- This parallelizes the new DWARF indexer. The indexer's storage was
- designed so that each storage object and each indexer is fully
- independent. This setup makes it simple to scan different CUs
- independently.
-
- This patch creates a new cooked index storage object per thread, and
- then scans a subset of all the CUs in each such thread, using gdb's
- existing thread pool.
-
- In the ongoing "gdb gdb" example, this patch reduces the wall time
- down to 0.668923, from 0.903534. (Note that the 0.903534 is the time
- for the new index -- that is, when the "enable the new index" patch is
- rebased to before this one. However, in the final series, that patch
- appears toward the end. Hopefully this isn't too confusing.)

-
- Pre-read DWARF section data
- Because BFD is not thread-safe, we need to be sure that any section
- data that is needed is read before trying to do any DWARF indexing in
- the background.
-
- This patch takes a simple approach to this -- it pre-reads the
- "info"-related sections. This is done for the main file, but also any
- auxiliary files as well, such as the DWO file.
-
- This patch could be perhaps enhanced by removing some now-redundant
- calls to dwarf2_section_info::read.
-
-2022-04-12 Tom Tromey <tom@tromey.com>
-
- Introduce thread-safe handling for complaints
- This introduces a new class that can be used to make the "complaint"
- code thread-safe. Instantiating the class installs a new handler that
- collects complaints, and then prints them all when the object is
- destroyed.
-
- This approach requires some locks. I couldn't think of a better way
- to handle this, though, because the I/O system is not thread-safe.
-
- It seemed to me that only GDB developers are likely to enable
- complaints, and because the complaint macro handle this case already
- (before any locks are required), I reasoned that any performance
- degradation that would result here would be fine.
-
- As an aside about complaints -- are they useful at all? I just ignore
- them, myself, since mostly they seem to indicate compiler problems
- that can't be solved in the GDB world anyway. I'd personally prefer
- them to be in a separate tool, like a hypothetical 'dwarflint'.

-
- Wire in the new DWARF indexer
- This wires the new DWARF indexer into the existing reader code. That
- is, this patch makes the modification necessary to enable the new
- indexer. It is not actually enabled by this patch -- that will be
- done later.
-
- I did a bit of performance testing for this patch and a few others. I
- copied my built gdb to /tmp, so that each test would be done on the
- same executable. Then, each time, I did:
-
- $ ./gdb -nx
- (gdb) maint time 1
- (gdb) file /tmp/gdb
-
- This patch is the baseline and on one machine came in at 1.598869 wall
- time.

-
- Implement quick_symbol_functions for cooked DWARF index
- This implements quick_symbol_functions for the cooked DWARF index.
- This is the code that interfaces between the new index and the rest of
- gdb. Cooked indexes still aren't created by anything.
-
- For the most part this is straightforward. It shares some concepts
- with the existing DWARF indices. However, because names are stored
- pre-split in the cooked index, name lookup here is necessarily
- different; see expand_symtabs_matching for the gory details.
-
-2022-04-12 Tom Tromey <tom@tromey.com>
-
- The new DWARF indexer
- This patch adds the code to index DWARF. This is just the scanner; it
- reads the DWARF and constructs the index, but nothing calls it yet.
-
- The indexer is split into two parts: a storage object and an indexer
- object. This is done to support the parallelization of this code -- a
- future patch will create a single storage object per thread.
-
-2022-04-12 Tom Tromey <tom@tromey.com>
-
- Introduce the new DWARF index class
- This patch introduces the new DWARF index class. It is called
- "cooked" to contrast against a "raw" index, which is mapped from disk
- without extra effort.
-
- Nothing constructs a cooked index yet. The essential idea here is
- that index entries are created via the "add" method; then when all the
- entries have been read, they are "finalize"d -- name canonicalization
- is performed and the entries are added to a sorted vector.
-
- Entries use the DWARF name (DW_AT_name) or linkage name, not the full
- name as is done for partial symbols.
-
- These two facets -- the short name and the deferred canonicalization
- -- help improve the performance of this approach. This will become
- clear in later patches, when parallelization is added.
-
- Some special code is needed for Ada, because GNAT only emits mangled
- ("encoded", in the Ada lingo) names, and so we reconstruct the
- hierarchical structure after the fact. This is also done in the
- finalization phase.
-
- One other aspect worth noting is that the way the "main" function is
- found is different in the new code. Currently gdb will notice
- DW_AT_main_subprogram, but won't recognize "main" during reading --
- this is done later, via explicit symbol lookup. This is done
- differently in the new code so that finalization can be done in the
- background without then requiring a synchronization to look up the
- symbol.

-
- Update skip_one_die for new abbrev properties
- This updates skip_one_die to speed it up in the cases where either
- sibling_offset or size_if_constant are set.
-
-2022-04-12 Tom Tromey <tom@tromey.com>
-
- Statically examine abbrev properties
- The new DIE scanner works more or less along the lines indicated by
- the text for the .debug_names section, disregarding the bugs in the
- specification.
-
- While working on this, I noticed that whether a DIE is interesting is
- a static property of the DIE's abbrev. It also turns out that many
- abbrevs imply a static size for the DIE data, and additionally that
- for many abbrevs, the sibling offset is stored at a constant offset
- from the start of the DIE.
-
- This patch changes the abbrev reader to analyze each abbrev and stash
- the results on the abbrev. These combine to speed up the new indexer.
- If the "interesting" flag is false, GDB knows to skip the DIE
- immediately. If the sibling offset is statically known, skipping can
- be done without reading any attributes; and in some other cases, the
- DIE can be skipped using simple arithmetic.
-
-2022-04-12 Tom Tromey <tom@tromey.com>
-
- Introduce DWARF abbrev cache
- The replacement for the DWARF psymbol reader works in a somewhat
- different way. The current reader reads and stores all the DIEs that
- might be interesting. Then, if it is missing a DIE, it re-scans the
- CU and reads them all. This approach is used for both intra- and
- inter-CU references.
-
- I instrumented the partial DIE hash to see how frequently it was used:
-
- [ 0] -> 1538165
- [ 1] -> 4912
- [ 2] -> 96102
- [ 3] -> 175
- [ 4] -> 244
-
- That is, most DIEs are never used, and some are looked up twice -- but
- this is just an artifact of the implementation of
- partial_die_info::fixup, which may do two lookups.
-
- Based on this, the new implementation doesn't try to store any DIEs,
- but instead just re-scans them on demand. In order to do this,
- though, it is convenient to have a cache of DWARF abbrevs. This way,
- if a second CU is needed to resolve an inter-CU reference, the abbrevs
- for that CU need only be computed a single time.
-
-2022-04-12 Tom Tromey <tom@tromey.com>
-
- Add "fullname" handling to file_and_directory
- This changes the file_and_directory object to be able to compute and
- cache the "fullname" in the same way that is done by other code, like
- the psymtab reader.
-
- Specialize std::hash for gdb_exception
- This adds a std::hash specialization for gdb_exception. This lets us
- store these objects in a hash table, which is used later in this
- series to de-duplicate the exception output from multiple threads.
-
- Return vector of results from parallel_for_each
- This changes gdb::parallel_for_each to return a vector of the results.
- However, if the passed-in function returns void, the return type
- remains 'void'. This functionality is used later, to parallelize the
- new indexer.
-
- Add batching parameter to parallel_for_each
- parallel_for_each currently requires each thread to process at least
- 10 elements. However, when indexing, it's fine for a thread to handle
- just a single CU. This patch parameterizes this, and updates the one
- user.
-
- Refactor build_type_psymtabs_reader
- The new DWARF scanner needs to save the entire cutu_reader object, not
- just parts of it. In order to make this possible, this patch
- refactors build_type_psymtabs_reader. This change is done separately
- because it is easy to review in isolation and it helps make the later
- patches smaller.
-
- Add new overload of dwarf5_djb_hash
- This adds a new overload of dwarf5_djb_hash. This is used in
- subsequent patches.
-
-2022-04-12 Tom Tromey <tom@tromey.com>
-
- Add name splitting
- The new DWARF index code works by keeping names pre-split. That is,
- rather than storing a symbol name like "a::b::c", the names "a", "b",
- and "c" will be stored separately.
-
- This patch introduces some helper code to split a full name into its
- components.
-
-2022-04-12 Tom Tromey <tom@tromey.com>
-
- Let skip_one_die not skip children
- This patch adds an option to skip_one_die that causes it not to skip
- child DIEs. This is needed in the new scanner.
-
- Allow ada_decode not to decode operators
- The new DWARF scanner records names as they appear in DWARF. However,
- because Ada is unusual, it also decodes the Ada names to synthesize
- package components for them. In order for this to work out properly,
- gdb also needs a mode where ada_decode can be instructed not to decode
- Ada operator names. That is what this patch implements.
-
- Refactor dwarf2_get_pc_bounds
- This changes dwarf2_get_pc_bounds so that it does not directly access
- a psymtab or psymtabs_addrmap. Instead, both the addrmap and the
- desired payload are passed as parameters. This makes it suitable to
- be used by the new indexer.
-
- Add dwarf2_per_cu_data::addresses_seen
- This adds a new member to dwarf2_per_cu_data that indicates whether
- addresses have been seen for this CU. This is then set by the
- .debug_aranges reader. The idea here is to detect when a CU does not
- have address information, so that the new indexer will know to do
- extra scanning in that case.
-
- Fix latent bug in read_addrmap_from_aranges
- Tom de Vries found a failure that we tracked down to a latent bug in
- read_addrmap_from_aranges (previously create_addrmap_from_aranges).
- The bug is that this code can erroneously reject .debug_aranges when
- dwz is in use, due to CUs at duplicate offsets. Because aranges can't
- refer to a CU coming from the dwz file, the fix is to simply skip such
- CUs in the loop.
-
- Split create_addrmap_from_aranges
- This patch splits create_addrmap_from_aranges into a wrapper function
- and a worker function. The worker function is then used in a later
- patch.
-
-2022-04-12 Tom Tromey <tom@tromey.com>
-
- Allow thread-pool.h to work without threads
- thread-pool.h requires CXX_STD_THREAD in order to even be included.
- However, there's no deep reason for this, and during review we found
- that one patch in the new DWARF indexer series unconditionally
- requires the thread pool.
-
- Because the thread pool already allows a task to be run in the calling
- thread (for example if it is configured to have no threads in the
- pool), it seemed straightforward to make this code ok to use when host
- threads aren't available at all.
-
- This patch implements this idea. I built it on a thread-less host
- (mingw, before my recent configure patch) and verified that the result
- builds.
-
- After the thread-pool change, parallel-for.h no longer needs any
- CXX_STD_THREAD checks at all, so this patch removes these as well.

- gas: further adjust file/line handling for .macro
- Commit 7992631e8c0b ("gas/Dwarf: improve debug info generation from .irp
- and alike blocks"), while dealing okay with actual assembly source files
- not using .file/.line and alike outside but not inside of .macro, has
- undue effects when the logical file/line pair was already overridden:
- Line numbers would continuously increment while processing the expanded
- macro, while the goal of the PR gas/16908 workaround is to keep the
- expansion associated with the line invoking the macro. However, as soon
- as enough state was overridden _inside_ the macro to cause as_where() to
- no longer fall back top as_where_physical(), honor this by resuming the
- bumping of the logical line number.
-
- Note that from_sb_is_expansion's initializer was 1 for an unknown
- reason. While renaming the variable and changing its type, also change
- the initializer to "expanding_none", which would have been "0" in the
- original code. Originally the initializer value itself wasn't ever used
- anyway (requiring sb_index != -1), as it necessarily had changed in
- input_scrub_include_sb() alongside setting sb_index to other than -1.
-
- Strictly speaking input_scrub_insert_line() perhaps shouldn't use
- expanding_none, yet none of the other enumerators fit there either. And
- then strictly speaking that function probably shouldn't exist in the
- first place. It's used only by tic54x.

- gas: further adjust file/line handling for .irp and alike
- Commit 7992631e8c0b ("gas/Dwarf: improve debug info generation from .irp
- and alike blocks"), while dealing okay with actual assembly source files
- not using .file/.line and alike outside but not inside of .irp et al,
- has undue effects when the logical file/line pair was already
- overridden: Line numbers would continuously increment upon every
- iteration, thus potentially getting far off. Furthermore it left it to
- the user to actually insert .file/.line inside such constructs. Note
- though that before aforementioned change things weren't pretty either:
- Diagnostics (and debug info) would be associated with the directive
- terminating the iteration construct, rather than with the actual lines.
-
- Handle this automatically by simply latching the present line and then
- re-instating coordinates first thing on every iteration; note that the
- file can't change from what was previously pushed on the scrubber's
- state stack, and hence can be taken from there by using a new flavor of
- .linefile (which is far better memory-footprint-wise than recording the
- full path in the inserted directive). (This then leaves undisturbed any
- file/line control occurring in the body of the construct, as these will
- only be seen and processed afterwards.)

- gdb/fortran: rewrite intrinsic handling and add some missing overloads
- The operators FLOOR, CEILING, CMPLX, LBOUND, UBOUND, and SIZE accept
- (some only with Fortran 2003) the optional parameter KIND. This
- parameter determines the kind of the associated return value. So far,
- implementation of this kind parameter has been missing in GDB.
- Additionally, the one argument overload for the CMPLX intrinsic function
- was not yet available.
-
- This patch adds overloads for all above mentioned functions to the
- Fortran intrinsics handling in GDB.
-
- It re-writes the intrinsic function handling section to use the helper
- methods wrap_unop_intrinsic/wrap_binop_intrinsic/wrap_triop_intrinsic.
- These methods define the action taken when a Fortran intrinsic function
- is called with a certain amount of arguments (1/2/3). The helper methods
- fortran_wrap2_kind and fortran_wrap3_kind have been added as equivalents
- to the existing wrap and wrap2 methods.
-
- After adding more overloads to the intrinsics handling, some of the
- operation names were no longer accurate. E.g. UNOP_FORTRAN_CEILING
- has been renamed to FORTRAN_CEILING as it is no longer a purely unary
- intrinsic function. This patch also introduces intrinsic functions with
- one, two, or three arguments to the Fortran parser and the
- UNOP_OR_BINOP_OR_TERNOP_INTRINSIC token has been added.

- gdb/fortran: Change GDB print for fortran default types
- Currently, when asking GDB to print the type of a Fortran default type
- such as INTEGER or REAL, GDB will return the default name of that type,
- e.g. "integer"/"real":
-
- (gdb) ptype integer
- type = integer
- (gdb) ptype real
- type = real
-
- For LOGICAL and COMPLEX it would return the actual underlying types
-
- (gdb) ptype logical
- type = logical*4
- (gdb) ptype complex
- type = complex*4
-
- Similarly, GDB would print the default integer type for the underlying
- default type:
-
- (gdb) ptype integer*4
- type = integer
- (gdb) ptype real*4
- type = real
- (gdb) ptype logical
- type = logical*4
- (gdb) ptype complex*4
- type = complex*4
-
- This is inconsistent and a bit confusing. Both options somehow indicate
- what the internal underlying type for the default type is - but I think
- the logical/complex version is a bit clearer.
-
- Consider again:
-
- (gdb) ptype integer
- type = integer
-
- This indicates to a user that the type of "integer" is Fortran's default
- integer type. Without examining "ptype integer*4" I would expect, that
- any variable declared integer in the actual code would also fit into a
- GDB integer. But, since we cannot adapt out internal types to the
- compiler flags used at compile time of a debugged binary, this might be
- wrong. Consider debugging Fortran code compiled with GNU and e.g. the
- "-fdefault-integer-8" flag. In this case the gfortran default integer
- would be integer*8 while GDB internally still would use a builtin_integer,
- so an integer of the size of an integer*4 type. On the other hand having
- GDB print
-
- (gdb) ptype integer
- type = integer*4
-
- makes this clearer. I would still be tempted to fit a variable declared
- integer in the code into a GDB integer - but at least ptype would
- directly tell me what is going on. Note, that when debugging a binary
- compiled with "-fdefault-integer-8" a user will always see the actual
- underlying type of any variable declared "integer" in the Fortran code.
- So having the code
-
- program test
- integer :: a = 5
- print *, a ! breakpt
- end program test
-
- will, when breaking at breakpt print
-
- (gdb) ptype var
- type = integer(kind=4)
-
- or
-
- (gdb) ptype var
- type = integer(kind=8)
-
- depending on the compiler flag.
-
- This patch changes the outputs for the REAL and INTEGER default types to
- actually print the internally used type over the default type name.
-
- The new behavior for the above examples is:
-
- (gdb) ptype integer
- type = integer*4
- (gdb) ptype integer*4
- type = integer*4
-
- Existing testcases have been adapted to reflect the new behavior.

- gdb/fortran: clean-up Fortran intrinsic types
- The currently implemented intrinsic type handling for Fortran missed some
- tokens and their parsing. While still not all Fortran type kinds are
- implemented this patch at least makes the currently handled types
- consistent. As an example for what this patch does, consider the
- intrinsic type INTEGER. GDB implemented the handling of the
- keywords "integer" and "integer_2" but missed "integer_4" and "integer_8"
- even though their corresponding internal types were already available as
- the Fortran builtin types builtin_integer and builtin_integer_s8.
- Similar problems applied to LOGICAL, REAL, and COMPLEX. This patch adds
- all missing tokens and their parsing. Whenever a section containing the
- type handling was touched, it also was reordered to be in a more easy to
- grasp order. All INTEGER/REAL/LOGICAL/COMPLEX types were grouped
- together and ordered ascending in their size making a missing one more
- easy to spot.
-
- Before this change GDB would print the following when tyring to use the
- INTEGER keywords:
-
- (gdb) set language fortran
- (gdb) ptype integer*1
- unsupported kind 1 for type integer
- (gdb) ptype integer_1
- No symbol table is loaded. Use the "file" command.
- (gdb) ptype integer*2
- type = integer*2
- (gdb) ptype integer_2
- type = integer*2
- (gdb) ptype integer*4
- type = integer
- (gdb) ptype integer_4
- No symbol table is loaded. Use the "file" command.
- (gdb) ptype integer*8
- type = integer*8
- (gdb) ptype integer_8
- No symbol table is loaded. Use the "file" command.
- (gdb) ptype integer
- type = integer
-
- With this patch all keywords are available and the GDB prints:
-
- (gdb) set language fortran
- (gdb) ptype integer*1
- type = integer*1
- (gdb) ptype integer_1
- type = integer*1
- (gdb) ptype integer*2
- type = integer*2
- (gdb) ptype integer_2
- type = integer*2
- (gdb) ptype integer*4
- type = integer*4
- (gdb) ptype integer_4
- type = integer*4
- (gdb) ptype integer*8
- type = integer*8
- (gdb) ptype integer_8
- type = integer*8
- (gdb) ptype integer
- type = integer
-
- The described changes have been applied to INTEGER, REAL, COMPLEX,
- and LOGICAL. Existing testcases have been adapted to reflect the
- new behavior. Tests for formerly missing types have been added.

- gdb/fortran: change default logical type to builtin_logical
- According to the Fortran standard, logical is of the size of a
- 'single numeric storage unit' (just like real and integer). For
- gfortran, flang and ifx/ifort this storage unit (or the default
- logical type) is of size kind 4, actually occupying 4 bytes of
- storage, and so the default type for logical expressions in
- Fortran should probably also be Logical*4 and not Logical*2. I
- adapted GDB's behavior to be in line with
- gfortran/ifort/ifx/flang.

- gdb/fortran: fix complex type in Fortran builtin types
- Before this patch things like
-
- (gdb) ptype complex*8
- complex*16
- (gdb) ptype complex*4
- complex*8
-
- were possible in GDB, which seems confusing for a user. The reason
- is a mixup in the implementation of the Fortran COMPLEX type. In
- Fortran the "*X" after a type would normally (I don't think this
- is language required) specify the type's size in memory. For the
- COMPLEX type the kind parameters usually (at least for GNU, Intel, Flang)
- specify not the size of the whole type but the size of the individual
- two REALs used to form the COMPLEX. Thus, a COMPLEX*4 will usually
- consist of two REAL*4s. Internally this type was represented by a
- builtin_complex_s8 - but here I think the s8 actually meant the raw
- size of the type. This is confusing and I renamed the types (e.g.
- builting_complex_s8 became builtin_complex_s4 according to its most
- common useage) and their printed names to their language equivalent.
- Additionally, I added the default COMPLEX type "COMPLEX" being the same
- as a COMPLEX*4 (as is normally the case) and removed the latter. I added
- a few tests for this new behavior as well.
-
- The new behavior is
-
- (gdb) ptype complex*8
- complex*8
- (gdb) ptype complex*4
- complex*4

- [gdb/testsuite] Fix gdb.base/annota1.exp with pie

- [gdb/testsuite] Fix gdb.dwarf2/dw2-lines.exp for m32 pie
- As reported in PR29043, when running test-case gdb.dwarf2/dw2-lines.exp with
- target board unix/-m32/-fPIE/-pie, we run into:
- ...
- Breakpoint 2, 0x56555540 in bar ()^M
- (gdb) PASS: gdb.dwarf2/dw2-lines.exp: cv=2: cdw=32: lv=2: ldw=32: \
- continue to breakpoint: foo \(1\)
- next^M
- Single stepping until exit from function bar,^M
- which has no line number information.^M
- 0x56555587 in main ()^M
- (gdb) FAIL: gdb.dwarf2/dw2-lines.exp: cv=2: cdw=32: lv=2: ldw=32: \
- next to foo (2)
- ...
-
- The problem is that the bar breakpoint ends up at an unexpected location
- because:
- - the synthetic debug info is incomplete and doesn't provide line info
- for the prologue part of the function, so consequently gdb uses the i386
- port prologue skipper to get past the prologue
- - the i386 port prologue skipper doesn't get past a get_pc_thunk call.
-
- Work around this in the test-case by breaking on bar_label instead.
-
- Tested on x86_64-linux with target boards unix, unix/-m32, unix/-fPIE/-pie and
- unix/-m32/-fPIE/-pie.

- gdb: Avoid undefined shifts, fix Go shifts
- I noticed that a build of GDB with GCC + --enable-ubsan, testing
- against GDBserver showed this GDB crash:
-
- (gdb) PASS: gdb.trace/trace-condition.exp: trace: 0x00abababcdcdcdcd << 46 == 0x7373400000000000: advance to trace begin
- tstart
- ../../src/gdb/valarith.c:1365:15: runtime error: left shift of 48320975398096333 by 46 places cannot be represented in type 'long int'
- ERROR: GDB process no longer exists
- GDB process exited with wait status 269549 exp9 0 1
- UNRESOLVED: gdb.trace/trace-condition.exp: trace: 0x00abababcdcdcdcd << 46 == 0x7373400000000000: start trace experiment
-
- The problem is that, "0x00abababcdcdcdcd << 46" is an undefined signed
- left shift, because the result is not representable in the type of the
- lhs, which is signed. This actually became defined in C++20, and if
- you compile with "g++ -std=c++20 -Wall", you'll see that GCC no longer
- warns about it, while it warns if you specify prior language versions.
-
- While at it, there are a couple other situations that are undefined
- (and are still undefined in C++20) and result in GDB dying: shifting
- by a negative ammount, or by >= than the bit size of the promoted lhs.
- For the latter, GDB shifts using (U)LONGEST internally, so you have to
- shift by >= 64 bits to see it:
-
- $ gdb --batch -q -ex "p 1 << -1"
- ../../src/gdb/valarith.c:1365:15: runtime error: shift exponent -1 is negative
- $ # gdb exited
-
- $ gdb --batch -q -ex "p 1 << 64"
- ../../src/gdb/valarith.c:1365:15: runtime error: shift exponent 64 is too large for 64-bit type 'long int'
- $ # gdb exited
-
- Also, right shifting a negative value is implementation-defined
- (before C++20, after which it is defined). For this, I chose to
- change nothing in GDB other than adding tests, as I don't really know
- whether we need to do anything. AFAIK, most implementations do an
- arithmetic right shift, and it may be we don't support any host or
- target that behaves differently. Plus, this becomes defined in C++20
- exactly as arithmetic right shift.
-
- Compilers don't error out on such shifts, at best they warn, so I
- think GDB should just continue doing the shifts anyhow too.
-
- Thus:
-
- - Adjust scalar_binop to avoid the undefined paths, either by adding
- explicit result paths, or by casting the lhs of the left shift to
- unsigned, as appropriate.
-
- For the shifts by a too-large count, I made the result be what you'd
- get if you split the large count in a series of smaller shifts.
- Thus:
-
- Left shift, positive or negative lhs:
-
- V << 64
- => V << 16 << 16 << 16 << 16
- => 0
-
- Right shift, positive lhs:
-
- Vpos >> 64
- => Vpos >> 16 >> 16 >> 16 >> 16
- => 0
-
- Right shift, negative lhs:
-
- Vneg >> 64
- => Vneg >> 16 >> 16 >> 16 >> 16
- => -1
-
- This is actually Go's semantics (the compiler really emits
- instructions to make it so that you get 0 or -1 if you have a
- too-large shift). So for that language GDB does the shift and
- nothing else. For other C-like languages where such a shift is
- undefined, GDB warns in addition to performing the shift.
-
- For shift by a negative count, for Go, this is a hard error. For
- other languages, since their compilers only warn, I made GDB warn
- too. The semantics I chose (we're free to pick them since this is
- undefined behavior) is as-if you had shifted by the count cast to
- unsigned, thus as if you had shifted by a too-large count, thus the
- same as the previous scenario illustrated above.
-
- Examples:
-
- (gdb) set language go
- (gdb) p 1 << 100
- $1 = 0
- (gdb) p -1 << 100
- $2 = 0
- (gdb) p 1 >> 100
- $3 = 0
- (gdb) p -1 >> 100
- $4 = -1
- (gdb) p -2 >> 100
- $5 = -1
- (gdb) p 1 << -1
- left shift count is negative
-
- (gdb) set language c
- (gdb) p -2 >> 100
- warning: right shift count >= width of type
- $6 = -1
- (gdb) p -2 << 100
- warning: left shift count >= width of type
- $7 = 0
- (gdb) p 1 << -1
- warning: left shift count is negative
- $8 = 0
- (gdb) p -1 >> -1
- warning: right shift count is negative
- $9 = -1
-
- - The warnings' texts are the same as what GCC prints.
-
- - Add comprehensive tests in a new gdb.base/bitshift.exp testcase, so
- that we exercise all these scenarios.

- Pass PKG_CONFIG_PATH down from top-level Makefile
- [Sending to binutils, gdb-patches and gcc-patches, since it touches the
- top-level Makefile/configure]
-
- I have my debuginfod library installed in a non-standard location
- (/opt/debuginfod), which requires me to set
- PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config. If I just set it during
- configure:
-
- $ PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config ./configure --with-debuginfod
- $ make
-
- or
-
- $ ./configure --with-debuginfod PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config
- $ make
-
- Then PKG_CONFIG_PATH is only present (and ignored) during the top-level
- configure. When running make (which runs gdb's and binutils'
- configure), PKG_CONFIG_PATH is not set, which results in their configure
- script not finding the library:
-
- checking for libdebuginfod >= 0.179... no
- configure: error: "--with-debuginfod was given, but libdebuginfod is missing or unusable."
-
- Change the top-level configure/Makefile system to capture the value
- passed when configuring the top-level and pass it down to
- subdirectories (similar to CFLAGS, LDFLAGS, etc).
-
- I don't know much about the top-level build system, so I really don't
- know if I did this correctly. The changes are:
-
- - Use AC_SUBST(PKG_CONFIG_PATH) in configure.ac, so that
- @PKG_CONFIG_PATH@ gets replaced with the actual PKG_CONFIG_PATH value
- in config files (i.e. Makefile)
- - Add a PKG_CONFIG_PATH Makefile variable in Makefile.tpl, initialized
- to @PKG_CONFIG_PATH@
- - Add PKG_CONFIG_PATH to HOST_EXPORTS in Makefile.tpl, which are the
- variables set when running the sub-configures
-
- I initially added PKG_CONFIG_PATH to flags_to_pass, in Makefile.def, but
- I don't think it's needed. AFAIU, this defines the flags to pass down
- when calling "make" in subdirectories. We only need PKG_CONFIG_PATH to
- be passed down during configure. After that, it's captured in
- gdb/config.status, so even if a "make" causes a re-configure later
- (because gdb/configure has changed, for example), the PKG_CONFIG_PATH
- value will be remembered.
-
- ChangeLog:
-
- * configure.ac: Add AC_SUBST(PKG_CONFIG_PATH).
- * configure: Re-generate.
- * Makefile.tpl (HOST_EXPORTS): Pass PKG_CONFIG_PATH.
- (PKG_CONFIG_PATH): New.
- * Makefile.in: Re-generate.

-
- The test loads the binary in GDB, grabs the address of a symbol, strips

- as position independent, so the address GDB grabs in the first place
- isn't where the code ends up after running.
-
- Fix this by linking the binary as non-position-independent. The
- alternative would be to compute the relocated address where to place the
- breakpoint, but that's not very straightforward, unfortunately.
-
- I was confused for a while, I was trying to load the binary in GDB
- manually to get the symbol address, but GDB was telling me the symbol
- could not be found. Meanwhile, it clearly worked in gdb.log. The thing
- is that GDB strips the binary in-place, so we don't have access to the
- intermediary binary with symbols. Change the test to output the
- stripped binary to a separate file instead.

- gdb/fortran: add support for accessing fields of extended types
- Fortran 2003 supports type extension. This patch allows access
- to inherited members by using their fully qualified name as described
- in the Fortran standard.
-
- In doing so the patch also fixes a bug in GDB when trying to access the
- members of a base class in a derived class via the derived class' base
- class member.
-
- This patch fixes PR22497 and PR26373 on GDB side.
-
- Using the example Fortran program from PR22497
-
- program mvce
- implicit none
-
- type :: my_type
- integer :: my_int
- end type my_type
-
- type, extends(my_type) :: extended_type
- end type extended_type
-
- type(my_type) :: foo
- type(extended_type) :: bar
-
- foo%my_int = 0
- bar%my_int = 1
-
- print*, foo, bar
-
- end program mvce
-
- and running this with GDB and setting a BP at 17:
-
- Before:
- (gdb) p bar%my_type
- A syntax error in expression, near `my_type'.
- (gdb) p bar%my_int
- There is no member named my_int.
- (gdb) p bar%my_type%my_int
- A syntax error in expression, near `my_type%my_int'.
- (gdb) p bar
- $1 = ( my_type = ( my_int = 1 ) )
-
- After:
- (gdb) p bar%my_type
- $1 = ( my_int = 1 )
- (gdb) p bar%my_int
- $2 = 1 # this line requires DW_TAG_inheritance to work
- (gdb) p bar%my_type%my_int
- $3 = 1
- (gdb) p bar
- $4 = ( my_type = ( my_int = 1 ) )
-
- In the above example "p bar%my_int" requires the compiler to emit
- information about the inheritance relationship between extended_type
- and my_type which gfortran and flang currently do not de. The
- respective issue gcc/49475 has been put as kfail.

- gdb/fortran: fix fetching assumed rank array content
- Commit:
-
- commit df7a7bdd9766adebc6b117c31bc617d81c1efd43
- Date: Thu Mar 17 18:56:23 2022 +0000
-
- gdb: add support for Fortran's ASSUMED RANK arrays
-
- Added support for Fortran assumed rank arrays. Unfortunately, this
- commit contained a bug that means though GDB can correctly calculate
- the rank of an assumed rank array, GDB can't fetch the contents of an
- assumed rank array.
-
- The history of this patch can be seen on the mailing list here:
-
- https://sourceware.org/pipermail/gdb-patches/2022-January/185306.html
-
- The patches that were finally committed can be found here:
-
- https://sourceware.org/pipermail/gdb-patches/2022-March/186906.html
-
- The original patches did support fetching the array contents, it was
- only the later series that introduced the regression.
-
- The problem is that when calculating the array rank the result is a
- count of the number of ranks, i.e. this is a 1 based result, 1, 2, 3,
- etc.
-
- In contrast, when computing the details of any particular rank the
- value passed to the DWARF expression evaluator should be a 0 based
- rank offset, i.e. a 0 based number, 0, 1, 2, etc.
-
- In the patches that were originally merged, this was not the case, and
- we were passing the 1 based rank number to the expression evaluator,
- e.g. passing 1 when we should pass 0, 2 when we should pass 1, etc.
- As a result the DWARF expression evaluator was reading the
- wrong (undefined) memory, and returning garbage results.
-
- In this commit I have extended the test case to cover checking the
- array contents, I've then ensured we make use of the correct rank
- value, and extended some comments, and added or adjusted some asserts
- as appropriate.

- gdb/testsuite: add "macros" option to gdb_compile
- Make gdb_compile handle a new "macros" option, which makes it pass the
- appropriate flag to make the compiler include macro information in the
- debug info. This will help simplify tests using macros, reduce
- redundant code, and make it easier to add support for a new compiler.
-
- Right now it only handles clang specially (using -fdebug-macro) and
- falls back to -g3 otherwise (which works for gcc). Other compilers can
- be added as needed.
-
- There are some tests that are currently skipped if the compiler is nor
- gcc nor clang. After this patch, the tests will attempt to run (the -g3
- fall back will be used). That gives a chance to people using other
- compilers to notice something is wrong and maybe add support for their
- compiler. If it is needed to support a compiler that doesn't have a way
- to include macro information, then we can always introduce a
- "skip_macro_tests" that can be used to skip over them.

- [gdb/testsuite] Make gdb.base/annota1.exp more robust
- On openSUSE Tumbleweed I run into:
- ...
- FAIL: gdb.base/annota1.exp: run until main breakpoint (timeout)
- ...
-
- The problem is that the libthread_db message occurs at a location where it's
- not expected:
- ...
- Starting program: outputs/gdb.base/annota1/annota1 ^M
- ^M
- ^Z^Zstarting^M

- Using host libthread_db library "/lib64/libthread_db.so.1".^M
- ^M
- ^Z^Zbreakpoints-invalid^M
- ^M
- ...
-
- Fix this by making the matching more robust:
- - rewrite the regexp such that each annotation is on a single line,
- starting with \r\n\032\032 and ending with \r\n
- - add a regexp variable optional_re, that matches all possible optional
- output, and use it as a separator in the first part of the regexp
-
- Tested on x86_64-linux.

- gdb: remove symtab::dirname
- I think the symtab::dirname method is bogus, or at least very

- used to find that symtab's file during compilation (i.e. the directory
- the file refers to in the DWARF line header file table), or the
- directory part of the symtab's filename maybe. In fact, it returns the
- compilation unit's directory, which is the CWD of the compiler, at
- compilation time. At least for DWARF, if the symtab's filename is
- relative, it will be relative to that directory. But if the symtab's
- filename is absolute, then the directory returned by symtab::dirname has
- nothing to do with the symtab's filename.
-
- Remove symtab::dirname to avoid this confusion, change all users to
- fetch the same information through the compunit. At least, it will be
- clear that this is a compunit property, not a symtab property.

- Finally, delete the reggroup_next and reggroup_prev functions.

- Most of these changes are pretty straight forward, using range based

- are two places where the changes are less straight forward.
-
- In gdb/python/py-registers.c, the register group iterator needed to
- change slightly. As the iterator is tightly coupled to the gdbarch, I
- just fetch the register group vector from the gdbarch when needed, and
- use an index counter to find the next item from the vector when
- needed.
-
- In gdb/tui/tui-regs.c the tui_reg_next and tui_reg_prev functions are
- just wrappers around reggroup_next and reggroup_prev respectively.
- I've just inlined the logic of the old functions into the tui
- functions. As the tui function had its own special twist (wrap around

-
- gdb: always add the default register groups
- There's a set of 7 default register groups. If we don't add any
- gdbarch specific register groups during gdbarch initialisation, then
- when we iterate over the register groups using reggroup_next and
- reggroup_prev we will make use of these 7 default groups. See the use
- of default_groups in gdb/reggroups.c for details on this.
-
- However, if the gdbarch adds its own groups during gdbarch
- initialisation, then these groups will be used in preference to the
- default groups.
-
- A problem arises though if the particular architecture makes use of
- the target description mechanism. If the default target
- description(s) (i.e. those internal to GDB that are used when the user
- doesn't provide their own) don't mention any additional register
- groups then the default register groups will be used.
-
- But if the target description does mention additional groups then the
- default groups are not used, and instead, the groups from the target
- description are used.
-
- The problem with this is that what usually happens is that the target
- description will mention additional groups, e.g. groups for special
- registers. Most architectures that use target descriptions work
- around this by adding all (or most) of the default register groups in
- all cases. See i386_add_reggroups, aarch64_add_reggroups,
- riscv_add_reggroups, xtensa_add_reggroups, and others.
-
- In this patch, my suggestion is that we should just add the default
- register groups for every architecture, always. This change is in
- gdb/reggroups.c.
-
- All the remaining changes are me updating the various architectures to
- not add the default groups themselves.
-
- So, where will this change be visible to the user? I think the
- following commands will possibly change:
-
- * info registers / info all-registers:
-
- The user can provide a register group to these commands. For example,
- on csky, we previously never added the 'vector' group. Now, as a
- default group, this will be available, but (presumably) will not
- contain any registers. I don't think this is necessarily a bad
- thing, there's something to be said for having some consistent
- defaults available. There are other architectures that didn't add
- all 7 of the defaults, which will now have gained additional groups.
-
- * maint print reggroups
-
- This prints the set of all available groups. As a maintenance
- command I'm less concerned with the output changing here.
- Obviously, for the architectures that didn't previously add all the
- defaults, this list just got bigger.
-
- * maint print register-groups
-
- This prints all the registers, and the groups they are in. If the
- defaults were not previously being added then a register (obviously)
- can't appear in one of the default groups. Now the groups are
- available then registers might be in more groups than previously.
- However, this is again a maintenance command, so I'm less concerned
- about this changing.

- gdb/tui: fix 'tui reg next/prev' command when data window is hidden
- Start GDB like:
-
- $ gdb -q executable
- (gdb) start
- (gdb) layout src
- ... tui windows are now displayed ...
- (gdb) tui reg next
-
- At this point the data (register) window should be displayed, but will
- contain the message 'Register Values Unavailable', and at the console
- you'll see the message "unknown register group 'next'".
-
- The same happens with 'tui reg prev' (but the error message is
- slightly different).
-
- At this point you can continue to use 'tui reg next' and/or 'tui reg
- prev' and you'll keep getting the error message.
-
- The problem is that when the data (register) window is first
- displayed, it's current register group is nullptr. As a consequence
- tui_reg_next and tui_reg_prev (tui/tui-regs.c) will always just return
- nullptr, which triggers an error in tui_reg_command.
-
- In this commit I change tui_reg_next and tui_reg_prev so that they
- instead return the first and last register group respectively if the
- current register group is nullptr.
-
- So, after this, using 'tui reg next' will (in the above case) show the
- first register group, while 'tui reg prev' will display the last
- register group.

-
- gdb/tui: avoid theoretical bug with 'tui reg' command
- While looking at the 'tui reg' command as part of another patch, I
- spotted a theoretical bug.
-
- The 'tui reg' command takes the name of a register group, but also
- handles partial register group matches, though the partial match has to
- be unique. The current command logic goes:
-
- With the code as currently written, if a target description named a
- register group either 'prev' or 'next' then GDB would see this as an
- ambiguous register name, and refuse to switch groups.
-
- Naming a register group 'prev' or 'next' seems pretty unlikely, but,
- by adding a single else block we can prevent this problem.
-
- Now, if there's a 'prev' or 'next' register group, the user will not
- be able to select the group directly, the 'prev' and 'next' names will
- always iterate through the available groups instead. But at least the
- user could select their groups by iteration, rather than direct
- selection.

- (More stack frames follow...)
-
- It turns out that the problem is that the async event handler
- mechanism has been invoked, but this has not yet been initialized.
-
- If we look at gdb_init (in gdb/top.c) we can indeed see the call to
- gdb_init_signals is after the call to initialize_current_architecture.
-
- If I reorder the calls, moving gdb_init_signals earlier, then the
- initial error is resolved, however, things are still broken. I now
- see the same "Quit this debugging session? (y or n)" prompt, but when
- I provide an answer and press return GDB immediately crashes.
-
- So what's going on now? The next problem is that the call_readline
- field within the current_ui structure is not initialized, and this
- callback is invoked to process the reply I entered.
-
- The problem is that call_readline is setup as a result of calling
- set_top_level_interpreter, which is called from captured_main_1.
- Unfortunately, set_top_level_interpreter is called after gdb_init is
- called.
-
- I wondered how to solve this problem for a while, however, I don't
- know if there's an easy "just reorder some lines" solution here.
- Looking through captured_main_1 there seems to be a bunch of
- dependencies between printing various things, parsing config files,
- and setting up the interpreter. I'm sure there is a solution hiding
- in there somewhere.... I'm just not sure I want to spend any longer
- looking for it.
-
- So.
-
- I propose a simpler solution, more of a hack/work-around. In utils.c
- we already have a function filtered_printing_initialized, this is
- checked in a few places within internal_vproblem. In some of these
- cases the call gates whether or not GDB will query the user.
-
- My proposal is to add a new readline_initialized function, which
- checks if the current_ui has had readline initialized yet. If this is
- not the case then we should not attempt to query the user.
-
- After this change GDB prints the error message, the backtrace, and
- then aborts (including dumping core). This actually seems pretty sane
- as, if GDB has not yet made it through the initialization then it
- doesn't make much sense to allow the user to say "no, I don't want to
- quit the debug session" (I think).

- gas/Dwarf: record functions
- To help tools like addr2line looking up function names, in particular
- when dealing with e.g. PE/COFF binaries (linked from ELF objects), where
- there's no ELF symbol table to fall back to, emit minimalistic
- information for functions marked as such and having their size
- specified.
-
- Notes regarding the restriction to (pure) ELF:
- - I realize this is a layering violation; I don't see how to deal with
- that in a better way.
- - S_GET_SIZE(), when OBJ_MAYBE_ELF is defined, looks wrong: Unlike
- S_SET_SIZE() it does not check whether the hook is NULL.
- - symbol_get_obj(), when OBJ_MAYBE_ELF is defined, looks unusable, as
- its return type can only ever be one object format's type (and this
- may then not be ELF's).
-
- The new testcases are limited to x86 because I wanted to include the
- case where function size can't be determined yet at the time Dwarf2 info
- is generated. As .nops gains support by further targets, they could also
- be added here then (with, as necessary, expecations suitably relaxed to
- cover for insn size differences).

- gdb: don't copy entirely optimized out values in value_copy
- Bug 28980 shows that trying to value_copy an entirely optimized out
- value causes an internal error. The original bug report involves MI and
- some Python pretty printer, and is quite difficult to reproduce, but
- another easy way to reproduce (that is believed to be equivalent) was
- proposed:
-
- $ ./gdb -q -nx --data-directory=data-directory -ex "py print(gdb.Value(gdb.Value(5).type.optimized_out()))"
- /home/smarchi/src/binutils-gdb/gdb/value.c:1731: internal-error: value_copy: Assertion `arg->contents != nullptr' failed.
-
- This is caused by 5f8ab46bc691 ("gdb: constify parameter of
- value_copy"). It added an assertion that the contents buffer is
- allocated if the value is not lazy:
-
- if (!value_lazy (val))
- {
- gdb_assert (arg->contents != nullptr);
-
- This was based on the comment on value::contents, which suggest that
- this is the case:
-
- /* Actual contents of the value. Target byte-order. NULL or not
- valid if lazy is nonzero. */
- gdb::unique_xmalloc_ptr<gdb_byte> contents;
-
- However, it turns out that it can also be nullptr also if the value is
- entirely optimized out, for example on exit of
- allocate_optimized_out_value. That function creates a lazy value, marks
- the entire value as optimized out, and then clears the lazy flag. But
- contents remains nullptr.
-
- This wasn't a problem for value_copy before, because it was calling
- value_contents_all_raw on the input value, which caused contents to be
- allocated before doing the copy. This means that the input value to
- value_copy did not have its contents allocated on entry, but had it
- allocated on exit. The result value had it allocated on exit. And that
- we copied bytes for an entirely optimized out value (i.e. meaningless
- bytes).
-
- From here I see two choices:
-
- 1. respect the documented invariant that contents is nullptr only and
- only if the value is lazy, which means making
- allocate_optimized_out_value allocate contents
- 2. extend the cases where contents can be nullptr to also include
- values that are entirely optimized out (note that you could still
- have some entirely optimized out values that do have contents
- allocated, it depends on how they were created) and adjust
- value_copy accordingly
-
- Choice #1 is safe, but less efficient: it's not very useful to allocate
- a buffer for an entirely optimized out value. It's even a bit less
- efficient than what we had initially, because values coming out of
- allocate_optimized_out_value would now always get their contents
- allocated.
-
- Choice #2 would be more efficient than what we had before: giving an
- optimized out value without allocated contents to value_copy would
- result in an optimized out value without allocated contents (and the
- input value would still be without allocated contents on exit). But
- it's more risky, since it's difficult to ensure that all users of the
- contents (through the various_contents* accessors) are all fine with
- that new invariant.
-
- In this patch, I opt for choice #2, since I think it is a better
- direction than choice #1. #1 would be a pessimization, and if we go
- this way, I doubt that it will ever be revisited, it will just stay that
- way forever.
-
- Add a selftest to test this. I initially started to write it as a
- Python test (since the reproducer is in Python), but a selftest is more
- straightforward.

- Fix for v850e divq instruction
- This is the last of the correctness fixes I've been carrying around for the
- v850.
-
- Like the other recent fixes, this is another case where we haven't been as
- careful as we should WRT host vs target types. For the divq instruction
- both operands are 32 bit types. Yet in the simulator code we convert them
- from unsigned int to signed long by assignment. So 0xfffffffb (aka -5)
- turns into 4294967291 and naturally that changes the result of our division.
-
- The fix is simple, insert a cast to int32_t to force interpretation as a
- signed value.
-
- Testcase for the simulator is included. It has a trivial dependency on the
- bins patch.

-
- Fix "bins" simulation for v850e3v5
- I've been carrying this for a few years. One test in the GCC testsuite is
- failing due to a bug in the handling of the v850e3v5 instruction "bins".
-
- When the "bins" instruction specifies a 32bit bitfield size, the simulator
- exhibits undefined behavior by trying to shift a 32 bit quantity by 32 bits.
- In the case of a 32 bit shift, we know what the resultant mask should be. So
- we can just set it.
-
- That seemed better than using 1UL for the constant (on a 32bit host unsigned
- long might still just be 32 bits) or needlessly forcing everything to
- long long types.
-
- Thankfully the case where this shows up is only bins <src>, 0, 32, <dest>
- which would normally be encoded as a simple move.
-

- Enable ARMv8.1-m PACBTI support
- This set of changes enable support for the ARMv8.1-m PACBTI extensions [1].
-
- The goal of the PACBTI extensions is similar in scope to that of a-profile
- PAC/BTI (aarch64 only), but the underlying implementation is different.
-
- One important difference is that the pointer authentication code is stored
- in a separate register, thus we don't need to mask/unmask the return address
- from a function in order to produce a correct backtrace.
-
- The patch introduces the following modifications:
-
- - Extend the prologue analyser for 32-bit ARM to handle some instructions
- from ARMv8.1-m PACBTI: pac, aut, pacg, autg and bti. Also keep track of
- return address signing/authentication instructions.
-
- - Adds code to identify object file attributes that indicate the presence of
- ARMv8.1-m PACBTI (Tag_PAC_extension, Tag_BTI_extension, Tag_PACRET_use and
- Tag_BTI_use).
-
- - Adds support for DWARF pseudo-register RA_AUTH_CODE, as described in the
- aadwarf32 [2].
-
- - Extends the dwarf unwinder to track the value of RA_AUTH_CODE.
-
- - Decorates backtraces with the "[PAC]" identifier when a frame has signed
- the return address.
-
- - Makes GDB aware of a new XML feature "org.gnu.gdb.arm.m-profile-pacbti". This
- feature is not included as an XML file on GDB's side because it is only
- supported for bare metal targets.

- gdb: move gdb_disassembly_flag into a new disasm-flags.h file
- While working on the disassembler I was getting frustrated. Every
- time I touched disasm.h it seemed like every file in GDB would need to
- be rebuilt. Surely the disassembler can't be required by that many
- parts of GDB, right?
-
- Turns out that disasm.h is included in target.h, so pretty much every
- file was being rebuilt!
-
- The only thing from disasm.h that target.h needed is the
- gdb_disassembly_flag enum, as this is part of the target_ops api.
-
- In this commit I move gdb_disassembly_flag into its own file. This is
- then included in target.h and disasm.h, after which, the number of
- files that depend on disasm.h is much reduced.
-
- I also audited all the other includes of disasm.h and found that the
- includes in mep-tdep.c and python/py-registers.c are no longer needed,
- so I've removed these.
-
- Now, after changing disasm.h, GDB rebuilds much quicker.

- (gdb) FAIL: gdb.base/vfork-follow-parent.exp: resolution_method=schedule-multiple: continue to break_parent (the program exited)
-
- Here, we continue both the vfork parent and child, since
- schedule-multiple is on. The child exits, which un-freezes the parent
- and makes an exit event available to GDB. We expect GDB to consume this
- exit event and present it to the user. Here, we see that GDB shows the
- parent hitting a breakpoint before showing the child exit.
-
- Because of the vfork, we know that chronologically, the child exiting
- must have happend before the parent hitting a breakpoint. However,
- scheduling being what it is, it is possible for the parent to un-freeze
- and exit quickly, such that when GDB pulls events out of the kernel,
- exit events for both processes are available. And then, GDB may chose
- at random to return the one for the parent first. This is what I
- imagine what causes the failure shown above.
-
- We could change the test to expect both possible outcomes, but I wanted
- to avoid complicating the .exp file that way. Instead, add a variable
- that the parent loops on that we set only after we confirmed the exit of
- the child. That should ensure that the order is always the same.
-
- Note that I wasn't able to reproduce the failure, so I can't tell if
- this fix really fixes the problem.

- gdb/testsuite: fix intermittent failures in gdb.mi/mi-cmd-user-context.exp
- I got failures like this once on a CI:
-
- frame^M
- &"frame\n"^M
- ~"#0 child_sub_function () at /home/jenkins/workspace/binutils-gdb_master_build/arch/amd64/target_board/unix/src/binutils-gdb/gdb/testsuite/gdb.mi/user-selected-context-sync.c:33\n"^M
- ~"33\t dummy = !dummy; /* thread loop line */\n"^M
- ^done^M
- (gdb) ^M
- FAIL: gdb.mi/mi-cmd-user-context.exp: frame 1 (unexpected output)
-
- The problem is that the test expects the following regexp:
-
- ".*#0 0x.*"
-
- And that typically works, when the output of the frame command looks
- like:
-
- #0 0x00005555555551bb in child_sub_function () at ...
-
- Note the lack of hexadecimal address in the failing case. Whether or
- not the hexadecimal address is printed (roughly) depends on whether the
- current PC is at the beginning of a line. So depending on where thread
- 2 was when GDB stopped it (after thread 1 hit its breakpoint), we can
- get either output. Adjust the regexps to not expect an hexadecimal
- prefix (0x) but a function name instead (either child_sub_function or
- child_function). That one is always printed, and is also a good check
- that we are in the frame we expect.
-
- Note that for test "frame 5", we are showing a pthread frame (on my
- system), so the function name is internal to pthread, not something we
- can rely on. In that case, it's almost certain that we are not at the
- beginning of a line, or that we don't have debug info, so I think it's
- fine to expect the hex prefix.
-
- And for test "frame 6", it's ok to _not_ expect a hex prefix (what the
- test currently does), since we are showing thread 1, which has hit a
- breakpoint placed at the beginning of a line.
-
- When testing this, Tom de Vries pointed out that the current test code
- doesn't ensure that the child threads are in child_sub_function when
- they are stopped. If the scheduler chooses so, it is possible for the
- child threads to be still in the pthread_barrier_wait or child_function
- functions when they get stopped. So that would be another racy failure
- waiting to happen.
-
- The only way I can think of to ensure the child threads are in the
- child_sub_function function when they get stopped is to synchronize the
- threads using some variables instead of pthread_barrier_wait. So,
- replace the barrier with an array of flags (one per child thread). Each
- child thread flips its flag in child_sub_function to allow the main
- thread to make progress and eventually hit the breakpoint.
-
- I copied user-selected-context-sync.c to a new mi-cmd-user-context.c and
- made modifications to that, to avoid interfering with
- user-selected-context-sync.exp.

- gdb: resume ongoing step after handling fork or vfork
- The test introduced by this patch would fail in this configuration, with
- the native-gdbserver or native-extended-gdbserver boards:
-
- FAIL: gdb.threads/next-fork-other-thread.exp: fork_func=fork: target-non-stop=auto: non-stop=off: displaced-stepping=auto: i=2: next to for loop
-
- The problem is that the step operation is forgotten when handling the

-
- In the first snippet, we resume the stepping thread with the range-stepping (r)
- vCont command. But after handling the fork (detaching the fork child), we
- resumed the whole process freely. The stepping thread, which was paused by
- GDBserver while reporting the fork event, was therefore resumed freely, instead
- of confined to the addresses of the stepped line. Note that since this
- is a "next", it could be that we have entered a function, installed a
- step-resume breakpoint, and it's ok to continue freely the stepping
- thread, but that's not the case here. The two snippets shown above were
- next to each other in the logs.
-
- For the fork case, we can resume stepping right after handling the
- event.
-
- However, for the vfork case, where we are waiting for the
- external child process to exec or exit, we only resume the thread that
- called vfork, and keep the others stopped (see patch "gdb: fix handling of
- vfork by multi-threaded program" prior in this series). So we can't
- resume the stepping thread right now. Instead, do it after handling the
- vfork-done event.

- gdbserver: report correct status in thread stop race condition
- The test introduced by the following patch would sometimes fail in this
- configuration:
-
- FAIL: gdb.threads/next-fork-other-thread.exp: fork_func=vfork: target-non-stop=on: non-stop=off: displaced-stepping=auto: i=14: next to for loop
-
- The test has multiple threads constantly forking or vforking while the
- main thread keep doing "next"s.
-
- (After writing the commit message, I realized this also fixes a similar
- failure in gdb.threads/forking-threads-plus-breakpoint.exp with the
- native-gdbserver and native-extended-gdbserver boards.)
-
- As stop_all_threads is called, because the main thread finished its
- "next", it inevitably happens at some point that we ask the remote
- target to stop a thread and wait() reports that this thread stopped with
- a fork or vfork event, instead of the SIGSTOP we sent to try to stop it.
-
- While running this test, I attached to GDBserver and stopped at
- linux-low.cc:3626. We can see that the status pulled from the kernel
- for 2742805 is indeed a vfork event:
-
- (gdb) p/x w
- $3 = 0x2057f
- (gdb) p WIFSTOPPED(w)
- $4 = true
- (gdb) p WSTOPSIG(w)
- $5 = 5
- (gdb) p/x (w >> 8) & (PTRACE_EVENT_VFORK << 8)
- $6 = 0x200
-
- However, the statement at line 3626 overrides that:
-
- ourstatus->set_stopped (gdb_signal_from_host (WSTOPSIG (w)));
-
- OURSTATUS becomes "stopped by a SIGTRAP". The information about the
- fork or vfork is lost.
-
- It's then all downhill from there, stop_all_threads eventually asks for
- a thread list update. That thread list includes the child of that
- forgotten fork or vfork, the remote target goes "oh cool, a new process,
- let's attach to it!", when in fact that vfork child's destiny was to be
- detached.
-
- My reverse-engineered understanding of the code around there is that the
- if/else between lines 3562 and 3583 (in the original code) makes sure
- OURSTATUS is always initialized (not "ignore"). Either the details are
- already in event_child->waitstatus (in the case of fork/vfork, for
- example), in which case we just copy event_child->waitstatus to
- ourstatus. Or, if the event is a plain "stopped by a signal" or a
- syscall event, OURSTATUS is set to "stopped", but without a signal
- number. Lines 3601 to 3629 (in the original code) serve to fill in that
- last bit of information.
-
- The problem is that when `w` holds the vfork status, the code wrongfully
- takes this branch, because WSTOPSIG(w) returns SIGTRAP:
-
- else if (current_thread->last_resume_kind == resume_stop
- && WSTOPSIG (w) != SIGSTOP)
-
- The intent of this branch is, for example, when we sent SIGSTOP to try
- to stop a thread, but wait() reports that it stopped with another signal
- (that it must have received from somewhere else simultaneously), say
- SIGWINCH. In that case, we want to report the SIGWINCH. But in our
- fork/vfork case, we don't want to take this branch, as the thread didn't
- really stop because it received a signal. For the non "stopped by a
- signal" and non "syscall signal" cases, we would ideally skip over all
- that snippet that fills in the signal or syscall number.
-
- The fix I propose is to move this snipppet of the else branch of the
- if/else above. In addition to moving the code, the last two "else if"
- branches:
-
- else if (current_thread->last_resume_kind == resume_stop
- && WSTOPSIG (w) != SIGSTOP)
- {
- /* A thread that has been requested to stop by GDB with vCont;t,
- but, it stopped for other reasons. */
- ourstatus->set_stopped (gdb_signal_from_host (WSTOPSIG (w)));
- }
- else if (ourstatus->kind () == TARGET_WAITKIND_STOPPED)
- ourstatus->set_stopped (gdb_signal_from_host (WSTOPSIG (w)));
-
- are changed into a single else:
-
- else
- ourstatus->set_stopped (gdb_signal_from_host (WSTOPSIG (w)));
-
- This is the default path we take if:
-
- - W is not a syscall status
- - W does not represent a SIGSTOP that have sent to stop the thread and
- therefore want to suppress it

-
- gdb: fix handling of vfork by multi-threaded program (follow-fork-mode=parent, detach-on-fork=on)
- There is a problem with how GDB handles a vfork happening in a
- multi-threaded program. This problem was reported to me by somebody not
- using vfork directly, but using system(3) in a multi-threaded program,
- which may be implemented using vfork.
-
- This patch only deals about the follow-fork-mode=parent,
- detach-on-fork=on case, because it would be too much to chew at once to
- fix the bugs in the other cases as well (I tried).
-
- The problem
- -----------
-
- When a program vforks, the parent thread is suspended by the kernel
- until the child process exits or execs. Specifically, in a
- multi-threaded program, only the thread that called vfork is suspended,
- other threads keep running freely. This is documented in the vfork(2)
- man page ("Caveats" section).
-
- Let's suppose GDB is handling a vfork and the user's desire is to detach
- from the child. Before detaching the child, GDB must remove the software
- breakpoints inserted in the shared parent/child address space, in case
- there's a breakpoint in the path the child is going to take before
- exec'ing or exit'ing (unlikely, but possible). Otherwise the child could
- hit a breakpoint instruction while running outside the control of GDB,
- which would make it crash. GDB must also avoid re-inserting breakpoints
- in the parent as long as it didn't receive the "vfork done" event (that
- is, when the child has exited or execed): since the address space is
- shared with the child, that would re-insert breakpoints in the child
- process also. So what GDB does is:
-
- 1. Receive "vfork" event for the parent
- 2. Remove breakpoints from the (shared) address space and set
- program_space::breakpoints_not_allowed to avoid re-inserting them
- 3. Detach from the child thread
- 4. Resume the parent
- 5. Wait for and receive "vfork done" event for the parent
- 6. Clean program_space::breakpoints_not_allowed and re-insert
- breakpoints
- 7. Resume the parent
-
- Resuming the parent at step 4 is necessary in order for the kernel to
- report the "vfork done" event. The kernel won't report a ptrace event
- for a thread that is ptrace-stopped. But the theory behind this is that
- between steps 4 and 5, the parent won't actually do any progress even
- though it is ptrace-resumed, because the kernel keeps it suspended,
- waiting for the child to exec or exit. So it doesn't matter for that
- thread if breakpoints are not inserted.
-
- The problem is when the program is multi-threaded. In step 4, GDB
- resumes all threads of the parent. The thread that did the vfork stays
- suspended by the kernel, so that's fine. But other threads are running
- freely while breakpoints are removed, which is a problem because they
- could miss a breakpoint that they should have hit.
-
- The problem is present with all-stop and non-stop targets. The only
- difference is that with an all-stop targets, the other threads are
- stopped by the target when it reports the vfork event and are resumed by
- the target when GDB resumes the parent. With a non-stop target, the
- other threads are simply never stopped.
-
- The fix
- -------
-
- There many combinations of settings to consider (all-stop/non-stop,
- target-non-stop on/off, follow-fork-mode parent/child, detach-on-fork
- on/off, schedule-multiple on/off), but for this patch I restrict the
- scope to follow-fork-mode=parent, detach-on-fork=on. That's the
- "default" case, where we detach the child and keep debugging the
- parent. I tried to fix them all, but it's just too much to do at once.
- The code paths and behaviors for when we don't detach the child are
- completely different.
-
- The guiding principle for this patch is that all threads of the vforking
- inferior should be stopped as long as breakpoints are removed. This is
- similar to handling in-line step-overs, in a way.
-
- For non-stop targets (the default on Linux native), this is what
- happens:
-
- - In follow_fork, we call stop_all_threads to stop all threads of the
- inferior
- - In follow_fork_inferior, we record the vfork parent thread in
- inferior::thread_waiting_for_vfork_done
- - Back in handle_inferior_event, we call keep_going, which resumes only
- the event thread (this is already the case, with a non-stop target).
- This is the thread that will be waiting for vfork-done.
- - When we get the vfork-done event, we go in the (new) handle_vfork_done
- function to restart the previously stopped threads.
-
- In the same scenario, but with an all-stop target:
-
- - In follow_fork, no need to stop all threads of the inferior, the
- target has stopped all threads of all its inferiors before returning
- the event.
- - In follow_fork_inferior, we record the vfork parent thread in
- inferior::thread_waiting_for_vfork_done.
- - Back in handle_inferior_event, we also call keep_going. However, we
- only want to resume the event thread here, not all inferior threads.
- In internal_resume_ptid (called by resume_1), we therefore now check
- whether one of the inferiors we are about to resume has
- thread_waiting_for_vfork_done set. If so, we only resume that
- thread.
-
- Note that when resuming multiple inferiors, one vforking and one not
- non-vforking, we could resume the vforking thread from the vforking
- inferior plus all threads from the non-vforking inferior. However,
- this is not implemented, it would require more work.
- - When we get the vfork-done event, the existing call to keep_going
- naturally resumes all threads.
-
- Testing-wise, add a test that tries to make the main thread hit a
- breakpoint while a secondary thread calls vfork. Without the fix, the
- main thread keeps going while breakpoints are removed, resulting in a
- missed breakpoint and the program exiting.

-
- gdb: replace inferior::waiting_for_vfork_done with inferior::thread_waiting_for_vfork_done
- The inferior::waiting_for_vfork_done flag indicates that some thread in
- that inferior is waiting for a vfork-done event. Subsequent patches
- will need to know which thread precisely is waiting for that event.
-
- Replace the boolean flag (waiting_for_vfork_done) with a thread_info
- pointer (thread_waiting_for_vfork_done).
-
- I think there is a latent buglet in that waiting_for_vfork_done is
- currently not reset on inferior exec or exit. I could imagine that if a
- thread in the parent process calls exec or exit while another thread of
- the parent process is waiting for its vfork child to exec or exit, we
- could end up with inferior::waiting_for_vfork_done without a thread
- actually waiting for a vfork-done event anymore. And since that flag is
- checked in resume_1, things could misbehave there.
-
- Since the new field points to a thread_info object, and those are
- destroyed on exec or exit, it could be worse now since we could try to
- access freed memory, if thread_waiting_for_vfork_done were to point to a
- stale thread_info. To avoid this, clear the field in
- infrun_inferior_exit and infrun_inferior_execd.

- timeout when my machine was more heavily loaded. Turns out the test
- is reading all the shared libraries over GDB's remote protocol, which
- can be slow.
-
- We avoid this in other tests by setting the sysroot in GDBFLAGS,
- something which is missing from the gdb.server/server-pipe.exp test.
-
- Fix the timeouts by setting sysroot in GDBFLAGS, after this the shared
- libraries are no longer copied over the remote protocol, and I no
- longer see the test timeout.

- Handle TLS variable lookups when using separate debug files.
- Commit df22c1e5d53c38f38bce6072bb46de240f9e0e2b handled the case that
- a separate debug file was passed as the objfile for a shared library
- to svr4_fetch_objfile_link_map. However, a separate debug file can
- also be passed for TLS variables in the main executable. In addition,
- frv_fetch_objfile_link_map also expects to be passed the original
- objfile rather than a separate debug file, so pull the code to resolve
- a separate debug file to the main objfile up into
- target_translate_tls_address.

- gdb: Add maint set ignore-prologue-end-flag
- The previous patch added support for the DWARF prologue-end flag in line
- table. This flag can be used by DWARF producers to indicate where to
- place breakpoints past a function prologue. However, this takes
- precedence over prologue analyzers. So if we have to debug a program
- with erroneous debug information, the overall debugging experience will
- be degraded.
-
- This commit proposes to add a maintenance command to instruct GDB to
- ignore the prologue_end flag.
-
- Tested on x86_64-gnu-linux.

- gdb: Add support for DW_LNS_set_prologue_end in line-table
- Add support for DW_LNS_set_prologue_end when building line-tables. This
- attribute can be set by the compiler to indicate that an instruction is
- an adequate place to set a breakpoint just after the prologue of a
- function.
-
- The compiler might set multiple prologue_end, but considering how
- current skip_prologue_using_sal works, this commit modifies it to accept
- the first instruction with this marker (if any) to be the place where a
- breakpoint should be placed to be at the end of the prologue.
-
- The need for this support came from a problematic usecase generated by
- hipcc (i.e. clang). The problem is as follows: There's a function
- (lets call it foo) which covers PC from 0xa800 to 0xa950. The body of
- foo begins with a call to an inlined function, covering from 0xa800 to
- 0xa94c. The issue is that when placing a breakpoint at 'foo', GDB
- inserts the breakpoint at 0xa818. The 0x18 offset is what GDB thinks is
- foo's first address past the prologue.
-
- Later, when hitting the breakpoint, GDB reports the stop within the
- inlined function because the PC falls in its range while the user
- expects to stop in FOO.
-
- Looking at the line-table for this location, we have:
-
- INDEX LINE ADDRESS IS-STMT
- [...]
- 14 293 0x000000000000a66c Y
- 15 END 0x000000000000a6e0 Y
- 16 287 0x000000000000a800 Y
- 17 END 0x000000000000a818 Y
- 18 287 0x000000000000a824 Y
- [...]
-
- For comparison, let's look at llvm-dwarfdump's output for this CU:
-
- Address Line Column File ISA Discriminator Flags
- ------------------ ------ ------ ------ --- ------------- -------------
- [...]
- 0x000000000000a66c 293 12 2 0 0 is_stmt

- 0x000000000000a828 100 58 82 0 0 is_stmt
- [...]
-
- The main difference we are interested in here is that llvm-dwarfdump's
- output tells us that 0xa800 is an adequate place to place a breakpoint
- past a function prologue. Since we know that foo covers from 0xa800 to
- 0xa94c, 0xa800 is the address at which the breakpoint should be placed
- if the user wants to break in foo.
-
- This commit proposes to add support for the prologue_end flag in the
- line-program processing.
-
- The processing of this prologue_end flag is made in skip_prologue_sal,
- before it calls gdbarch_skip_prologue_noexcept. The intent is that if
- the compiler gave information on where the prologue ends, we should use
- this information and not try to rely on architecture dependent logic to
- guess it.
-
- The testsuite have been executed using this patch on GNU/Linux x86_64.
- Testcases have been compiled with both gcc/g++ (verison 9.4.0) and
- clang/clang++ (version 10.0.0) since at the time of writing GCC does not
- set the prologue_end marker. Tests done with GCC 11.2.0 (not over the
- entire testsuite) show that it does not emit this flag either.
-
- No regression have been observed with GCC or Clang. Note that when
- using Clang, this patch fixes a failure in
- gdb.opt/inline-small-func.exp.

- gdb/buildsym: Line record use a record flag
- Currently when recording a line entry (with
- buildsym_compunit::record_line), a boolean argument argument is used to
- indicate that the is_stmt flag should be set for this particular record.
- As a later commit will add support for new flags, instead of adding a
- parameter to record_line for each possible flag, transform the current
- is_stmt parameter into a enum flag. This flags parameter will allow
- greater flexibility in future commits.
-
- This enum flags type is not propagated into the linetable_entry type as
- this would require a lot of changes across the codebase for no practical
- gain (it currently uses a bitfield where each interesting flag only
- occupy 1 bit in the structure).

- Remove some globals from nat/windows-nat.c
- nat/windows-nat.c has a number of globals that it uses to communicate
- with its clients (gdb and gdbserver). However, if we ever want the
- Windows ports to be multi-inferior, globals won't work.
-
- This patch takes a step toward that by moving most nat/windows-nat.c
- globals into a new struct windows_process_info. Many functions are
- converted to be methods on this object.
-
- A couple of globals remain, as they are needed to truly be global due
- to the way that the Windows debugging APIs work.
-
- The clients still have a global for the current process. That is,
- this patch is a step toward the end goal, but doesn't implement the
- goal itself.

- Add context-sensitive field name completion to Ada parser
- This updates the Ada expression parser to implement context-sensitive
- field name completion. This is PR ada/28727.
-
- This is somewhat complicated due to some choices in the Ada lexer --
- it chooses to represent a sequence of "."-separated identifiers as a
- single token, so the parser must partially recreate the completer's
- logic to find the completion word boundaries.
-
- Despite the minor warts in this patch, though, it is a decent

- Consolidate single-char tokens in ada-lex.l

- Also, this removes '.' from the list of such tokens. '.' is not used

-
- Remove the Ada DOT_ALL token
- The Ada parser has a DOT_ALL token to represent ".all", and another

- completion it is a bit more convenient to unify these cases, so this
- patch removes DOT_ALL.
-
- Refactor ada-lex.l:processId
- processId in ada-lex.l is a bit funny -- it uses an "if" and a
- "switch", and a nested loop. This patch cleans it up a bit, changing
- it to use a boolean flag and a simpler "if".
-
- Implement completion for Ada attributes
- This adds a completer for Ada attributes. Some work in the lexer is
- required in order to match end-of-input correctly, as flex does not
- have a general-purpose way of doing this. (The approach taken here is
- recommended in the flex manual.)

-
- Refactor expression completion
- This refactors the gdb expression completion code to make it easier to
- add more types of completers.
-
- In the old approach, just two kinds of completers were supported:
- field names for some sub-expression, or tag names (like "enum
- something"). The data for each kind was combined in single structure,
- "expr_completion_state", and handled explicitly by
- complete_expression.
-
- In the new approach, the parser state just holds an object that is
- responsible for implementing completion. This way, new completion
- types can be added by subclassing this base object.
-
- The structop completer is moved into structop_base_operation, and new
- objects are defined for use by the completion code. This moves much
- of the logic of expression completion out of completer.c as well.

- opcodes/i386: partially implement disassembler style support
- This commit adds partial support for disassembler styling in the i386
- disassembler.
-
- The i386 disassembler collects the instruction arguments into an array
- of strings, and then loops over the array printing the arguments out
- later on. The problem is that by the time we print the arguments out
- it's not obvious what the type of each argument is.
-
- Obviously this can be fixed, but I'd like to not do that as part of
- this commit, rather, I'd prefer to keep this commit as small as
- possible to get the basic infrastructure in place, then we can improve
- on this, to add additional styling, in later commits.
-
- For now then, I think this commit should correctly style mnemonics,
- some immediates, and comments. Everything else will be printed as
- plain text, which will include most instruction arguments, unless the
- argument is printed as a symbol, by calling the print_address_func
- callback.

- objdump/opcodes: add syntax highlighting to disassembler output
- This commit adds the _option_ of having disassembler output syntax
- highlighted in objdump. This option is _off_ by default. The new
- command line options are:
-
- --disassembler-color=off # The default.
- --disassembler-color=color
- --disassembler-color=extended-color
-
- I have implemented two colour modes, using the same option names as we
- use of --visualize-jumps, a basic 8-color mode ("color"), and an
- extended 8bit color mode ("extended-color").
-
- The syntax highlighting requires that each targets disassembler be
- updated; each time the disassembler produces some output we now pass
- through an additional parameter indicating what style should be
- applied to the text.
-
- As updating all target disassemblers is a large task, the old API is
- maintained. And so, a user of the disassembler (i.e. objdump, gdb)
- must provide two functions, the current non-styled print function, and
- a new, styled print function.
-
- I don't currently have a plan for converting every single target
- disassembler, my hope is that interested folk will update the
- disassemblers they are interested in. But it is possible some might
- never get updated.
-
- In this initial series I intend to convert the RISC-V disassembler
- completely, and also do a partial conversion of the x86 disassembler.
- Hopefully having the x86 disassembler at least partial converted will
- allow more people to try this out easily and provide feedback.
-
- In this commit I have focused on objdump. The changes to GDB at this
- point are the bare minimum required to get things compiling, GDB makes
- no use of the styling information to provide any colors, that will
- come later, if this commit is accepted.
-
- This first commit in the series doesn't convert any target
- disassemblers at all (the next two commits will update some targets),
- so after this commit, the only color you will see in the disassembler
- output, is that produced from objdump itself, e.g. from
- objdump_print_addr_with_sym, where we print an address and a symbol
- name, these are now printed with styling information, and so will have
- colors applied (if the option is on).
-
- Finally, my ability to pick "good" colors is ... well, terrible. I'm
- in no way committed to the colors I've picked here, so I encourage
- people to suggest new colors, or wait for this commit to land, and
- then patch the choice of colors.
-
- I do have an idea about using possibly an environment variable to
- allow the objdump colors to be customised, but I haven't done anything
- like that in this commit, the color choices are just fixed in the code
- for now.

- (PRMS minimal encodings)
- KPASS: gdb.ada/arrayptr.exp: scenario=minimal: print pa_ptr(3) \

-
- The test-case KFAILs some tests. However, the analysis in the corresponding
- PR talks of a compiler problem, so it should use XFAILs instead.
-
- The KFAILs are setup for pre-gcc-12, but apparantly the fix has been
- backported to system compiler 7.5.0, hence the KPASS.
-
- Fix this by:
- - using an XFAIL instead of a KFAIL
- - matching the specific gdb output that corresponds to the XFAILs
- (reproduced on Fedora 34).
-
- Tested on x86_64-linux, specifically openSUSE Leap 15.3 and Fedora 34.

- gdb: add support for Fortran's ASSUMED RANK arrays
- This patch adds a new dynamic property DYN_PROP_RANK, this property is
- read from the DW_AT_rank attribute and stored within the type just
- like other dynamic properties.
-
- As arrays with dynamic ranks make use of a single
- DW_TAG_generic_subrange to represent all ranks of the array, support
- for this tag has been added to dwarf2/read.c.
-
- The final piece of this puzzle is to add support in gdbtypes.c so that
- we can resolve an array type with dynamic rank. To do this the
- existing resolve_dynamic_array_or_string function is split into two,
- there's a new resolve_dynamic_array_or_string_1 core that is
- responsible for resolving each rank of the array, while the now outer
- resolve_dynamic_array_or_string is responsible for figuring out the
- array rank (which might require resolving a dynamic property) and then
- calling the inner core.
-
- The resolve_dynamic_range function now takes a rank, which is passed
- on to the dwarf expression evaluator. This rank will only be used in
- the case where the array itself has dynamic rank, but we now pass the
- rank in all cases, this should be harmless if the rank is not needed.
-
- The only small nit is that resolve_dynamic_type_internal actually
- handles resolving dynamic ranges itself, which now obviously requires
- us to pass a rank value. But what rank value to use? In the end I
- just passed '1' through here as a sane default, my thinking is that if
- we are in resolve_dynamic_type_internal to resolve a range, then the
- range isn't part of an array with dynamic rank, and so the range
- should actually be using the rank value at all.
-
- An alternative approach would be to make the rank value a
- gdb::optional, however, this ends up adding a bunch of complexity to
- the code (e.g. having to conditionally build the array to pass to
- dwarf2_evaluate_property, and handling the 'rank - 1' in
- resolve_dynamic_array_or_string_1) so I haven't done that, but could,
- if people think that would be a better approach.
-
- Finally, support for assumed rank arrays was only fixed very recently
- in gcc, so you'll need the latest gcc in order to run the tests for
- this.
-
- Here's an example test program:
-
- PROGRAM arank
- REAL :: a1(10)
- CALL sub1(a1)
-
- CONTAINS
-
- SUBROUTINE sub1(a)
- REAL :: a(..)
- PRINT *, RANK(a)
- END SUBROUTINE sub1
- END PROGRAM arank
-
- Compiler Version:
- gcc (GCC) 12.0.0 20211122 (experimental)
-
- Compilation command:
- gfortran assumedrank.f90 -gdwarf-5 -o assumedrank
-
- Without Patch:
-
- gdb -q assumedrank
- Reading symbols from assumedrank...
- (gdb) break sub1
- Breakpoint 1 at 0x4006ff: file assumedrank.f90, line 10.

- (gdb) print RANK(a)
- 'a' has unknown type; cast it to its declared type

- gdb/dwarf: pass an array of values to the dwarf evaluator
- When we need to evaluate a DWARF expression in order to resolve some
- dynamic property of a type we call the dwarf2_evaluate_property
- function, which is declared in gdb/dwarf/loc.h and defined in
- gdb/dwarf/loc.c.
-
- Currently, this function takes (amongst other things) an argument of
- type property_addr_info called addr_stack and a boolean called
- push_initial_value. When push_initial_value then the top value of
- addr_stack is pushed onto the dwarf expression evaluation stack before
- the expression is evaluated.
-
- So far this has worked fine, as the only two cases we needed to handle
- are the case the DWARF expression doesn't require the object
- address (what the top of addr_stack represents), and the case where
- the DWARF expression does require the address.
-
- In the next commit this is going to change. As we add support for
- Fortran assumed rank arrays, we need to start resolving the dynamic
- properties of arrays. To do this, we need to push the array rank onto
- the dwarf expression evaluation stack before the expression is
- evaluated.
-
- This commit is a refactoring commit aimed at making it easier to
- support Fortran assumed rank arrays. Instead of passing a boolean,
- and using this to decide if we should push the object address or not,
- we instead pass an array (view) of values that should be pushed to the
- dwarf expression evaluation stack.
-
- In the couple of places where we previously passed push_initial_value
- as true (mostly this was defaulting to false), we now have to pass the
- address from the addr_stack as an item in the array view.
-
- In the next commit, when we want to handle passing the array rank,
- this will easily be supported too.
-
- There should be no user visible changes after this commit.

- gdb: small simplification in dwarf2_locexpr_baton_eval
- While examining the dwarf expression evaluator, I noticed that in

- This allows for a small cleanup, replacing an if/then/else with an
- assertion.

- gdb/testsuite: resolve some duplicate test names in gdb.base
- This commit resolves all the duplicate test names that I see in the
- script:
-
- gdb.base/attach-pie-misread.exp
-
- The duplicate names all come from a second call to
- build_executable_own_libs, so in this commit I've places the second
- call inside a with_test_prefix block.
-
- While I was making this change I've also modified the value being
- passed as the testname for the second build_executable_own_libs call.
- Previously we used ${test}, however, I think this was likely a
- mistake, the 'test' variable is setup for the previous test. I
- suspect that ${testfile} is a better choice - especially now we have a
- testname prefix.
-
- As the testname is only used (after various calls) from within
- build_executable_from_specs should the build fail, I don't think this
- change really makes much difference though.
-
- There should be no change in what is tested after this commit.

- gdb/Makefile.in: move ALLDEPFILES earlier in Makefile.in
- If I do 'make tags' in the gdb build directory, the tags target does
- complete, but I see these warnings:
-
- ../../src/gdb/arm.c: No such file or directory
- ../../src/gdb/arm-get-next-pcs.c: No such file or directory
- ../../src/gdb/arm-linux.c: No such file or directory
-
- The reason for this is the ordering of build rules and make variables
- in gdb/Makefile.in, specifically, the placement of the tags related
- rules, and the ALLDEPFILES variable. The ordering is like this:
-
- TAGFILES_NO_SRCDIR = .... $(ALLDEPFILES) ....
-
- TAGS: $(TAGFILES_NO_SRCDIR) ....
- # Recipe uses $(TAGFILES_NO_SRCDIR)
-
- tags: TAGS
-
- ALLDEPFILES = .....
-
- When the TAGS rule is parsed TAGFILES_NO_SRCDIR is expanded, which
- then expands ALLDEPFILES, which, at that point in the Makefile is
- undefined, and so expands to the empty string. As a result TAGS does
- not depend on any file listed in ALLDEPFILES.
-
- However, when the TAGS recipe is invoked ALLDEPFILES is now defined.
- As a result, all the files in ALLDEPFILES are passed to the etags
- program.
-
- The ALLDEPFILES references three files, arm.c, arm-get-next-pcs.c, and
- arm-linux.c, which are actually in the gdb/arch/ directory, but, in
- ALLDEPFILES these files don't include the arch/ prefix. As a result,
- the etags program ends up looking for these files in the wrong
- location.
-
- As ALLDEPFILES is only used by the TAGS rule, this mistake was not
- previously noticed (the TAGS rule itself was broken until a recent
- commit).
-
- In this commit I make two changes, first, I move ALLDEPFILES to be
- defined before TAGFILES_NO_SRCDIR, this means that the TAGS rule will
- depend on all the files in ALLDEPFILES. With this change the TAGS
- rule now breaks complaining that there's no rule to build the 3 files
- mentioned above.
-
- Next, I have added all *.c files in gdb/arch/ to ALLDEPFILES,
- including their arch/ prefix, and removed the incorrect (missing arch/
- prefix) references.
-
- With these two changes the TAGS (or tags if you prefer) target now
- builds without any errors or warnings.

- gdb/tui: fair split of delta after a resize
- Currently, in master gdb, when a tui window is changed in size, the
- screen delta is mostly just added to the next available window. We
- do take care to respect the min/max size, but in most cases, these
- limits are just "the terminal size", and so, we end up placing the
- whole delta on the next window.
-
- Consider these steps in an 80 column, 24 line terminal:
-
- (gdb) tui enable
- (gdb) layout src
- (gdb) layout split
- (gdb) info win
- Name Lines Columns Focus
- src 8 80 (has focus)
- asm 8 80
- status 1 80
- cmd 8 80
- (gdb) winheight cmd +2
- (gdb) info win
- Name Lines Columns Focus
- src 6 80 (has focus)
- asm 8 80
- status 1 80
- cmd 10 80
-
- Notice that initially, the windows were balanced, 8 lines each for the
- major windows. Then, when the cmd window was adjusted, the extra two
- lines were given to the asm window.
-
- I think it would be nicer if the delta was spread more evenly over the
- available windows. In the example above, after the adjustment the
- layout now looks like:
-
- (gdb) info win
- Name Lines Columns Focus
- src 7 80 (has focus)
- asm 7 80
- status 1 80
- cmd 10 80
-
- This is achieved within tui_layout_split::set_size, by just handing
- out the delta in increments of 1 to each window (except for the window
- the user adjusted), until there's no more delta left. Of course, we
- continue to respect the min/max window sizes.

- gdb/tui: relax restrictions on window max height and width
- This commit removes some arbitrary adjustments made in
- tui_cmd_window::max_height, tui_win_info::max_height, and
- tui_win_info::max_width.
-
- These member functions all subtract some constant from the theoretical
- maximum height or width. I've looked back through the history a
- little and can see no real reason why these adjustments should be
- needed, with these adjustments removed all the existing tui tests
- still pass.
-
- However, retaining these restrictions causes some bugs, consider:
-
- (gdb) tui new-layout hsrc {-horizontal src 1 cmd 1} 1
-
- When this layout is selected with current master, gdb will leave a 4
- line gap at the bottom of the terminal.
-
- The problem is that the maximum height is restricted, for the cmd
- window, to 4 less than the terminal height.
-
- By removing this restriction gdb is able to size the windows to the
- complete terminal height, and the layout is done correctly.
-
- This 4 line restriction is also what prevents this layout from working
- correctly:
-
- (gdb) tui new-layout conly cmd 1
-
- Previously, this layout would present a cmd window only, but there
- would be a 4 line gap at the bottom of the terminal. This issue was
- mentioned in an earlier commit in this series (when a different bug
- was fixed), but with this commit, the above layout now correctly fills
- the terminal. The associated test is updated.
-
- After removing the adjustment in tui_cmd_window::max_height, the
- implementation is now the same as the implementation in the parent
- class tui_win_info, so I've completely removed the max_height call
- from tui_cmd_window.

- gdb/testsuite: some additional tests in gdb.tui/scroll.exp
- This commit just adds an extra check of the src window size prior to
- sending all the commands to gdb. We also set the cmd window height to

- winheight and recheck are just extras. All of these test pass both

-
- gdb/tui: support placing the cmd window into a horizontal layout
- This commit allows the user to place the cmd window within horizontal
- tui layouts. Consider this set of steps, carried out in an 80 columns
- by 24 lines terminal, using current master gdb:
-
- (gdb) tui new-layout hsrc { -horizontal src 1 cmd 1 } 1 status 1
- (gdb) tui layout hsrc
-
- What you end up with is a full width cmd window with the status bar
- beneath. Where's the src window gone? We then try:
-
- (gdb) info win
- Name Lines Columns Focus
- src 23 3 (has focus)
- cmd 23 80
- status 1 80
- (gdb)
-
- Something weird has gone on, gdb has overlapped the cmd window with
- the src window. If we trigger the src window to redraw is content,
- for example, 'list main', then we see corruption in the cmd window as
- the src window overwrites it.
-
- So, what's going on?
-
- The problem is some code in tui_layout_split::apply, in tui-layout.c.
- Within 'Step 1', there is a loop that calculates the min/max window
- sizes for all windows within a tui_layout_split. However, there's a
- special case for the cmd window.
-
- This special case is trying to have the cmd window retain its current
- size when a layout is re-applied, or a new layout is applied. This
- makes sense, consider moving from the 'src' layout to the 'asm'
- layout, this looks something like this (status window removed):
-
- .-------. .-------.
- | src | | asm |
- |-------| ====> |-------|
- | cmd | | cmd |
- '-------' '-------'
-
- If the user has gone to the effort of adjusting the cmd window size,
- then, the thinking goes, we shouldn't reset the cmd window size when
- switching layouts like this.
-
- The problem though, is that when we do a switch more like this:
-
- .-----------. .-----------.
- | src | | | |
- |-----------| ====> | asm | cmd |
- | cmd | | | |
- '-----------' '-----------'
-
- Now retaining the cmd window width makes no sense; the new layout has
- a completely different placement for the cmd window, instead of sizing
- by height, we're now sizing by width. The existing code doesn't
- understand this though, and tried to retain the full width for the cmd
- window.
-
- To solve this problem, I propose we introduce the idea of a layout
- "fingerprint". The fingerprint tries to capture, in an abstract way,
- where the cmd window lives within the layout.
-
- Only when two layouts have the same fingerprint will we attempt to
- retain the cmd window size.
-
- The fingerprint for a layout is represented as a string, the string is
- a series of 'V' or 'H' characters, ending with a single 'C'
- character. The series of 'V' and 'H' characters represent the
- vertical or horizontal layouts that must be passed through to find the
- cmd window.
-
- Here are a few examples:
-
- # This layout is equivalent to the builtin 'src' layout.
- # Fingerprint: VC
- tui new-layout example1 src 2 status 0 cmd 1
-
- # This layout is equivalent to the builtin 'split' layout.
- # Fingerprint: VC
- tui new-layout example2 src 1 asm 1 status 0 cmd 1
-
- # This is the same layout that was given at the top.
- # Fingerprint: VHC
- tui new-layout hsrc { -horizontal src 1 cmd 1 } 1 status 1
-
- And so, when switching between example1 and example2, gdb knows that
- the cmd window is, basically, in the same sort of position within the
- layout, and will retain the cmd window size.
-
- In contrast, when switching to the hsrc layout, gdb understands that
- the position of the cmd window is different, and does not try to
- retain the cmd window size.
-
-2022-04-03 Andrew Burgess <aburgess@redhat.com>
-
- gdb/tui: allow cmd window to change size in tui_layout_split::apply
- When we switch layouts we call the tui_layout_split::apply member
- function to reapply the layout, and recalculate all the window sizes.
-
- One special case is the cmd window, which we try to keep at its
- existing size.
-
- However, in some cases it is not appropriate to keep the cmd window at
- its existing size. I will describe two such cases here, in one, we
- want the cmd window to reduce in size, and in the other, we want the
- cmd window to grow in size.
-
- Try these steps in a 80 columns, by 24 lines terminal:
-
- (gdb) tui enable
- (gdb) layout src
- (gdb) winheight cmd 20
- (gdb) layout split
-
- You should see that the status window is missing from the new layout,
- and that the cmd window has been placed over the border of the asm
- window. The 'info win' output is:
-
- (gdb) info win
- Name Lines Columns Focus
- src 3 80 (has focus)
- asm 3 80
- status 1 80
- cmd 20 80
-
- Notice that gdb has assigned 27 lines of screen space, even with the
- border overlap between the src and asm windows, this is still 2 lines
- too many.
-
- The problem here is that after switching layouts, gdb has forced the
- cmd window to retain its 20 line height. Really, we want the cmd
- window to reduce in height so that the src and asm windows can occupy
- their minimum required space.
-
- This commit allows this (details on how are below). After this
- commit, in the above situation, we now see the status window displayed
- correctly, and the 'info win' output is:
-
- (gdb) info win
- Name Lines Columns Focus
- src 3 80 (has focus)
- asm 3 80
- status 1 80
- cmd 18 80
-
- The cmd window has been reduced in size by 2 lines so that everything
- can fit on the screen.
-
- The second example is one which was discussed in a recent commit,
- consider this case (still in the 80 column, 24 line terminal):
-
- (gdb) tui enable
- (gdb) tui new-layout conly cmd 1
- (gdb) layout conly
- (gdb) info win
- Name Lines Columns Focus
- cmd 8 80 (has focus)
- (gdb)
-
- This layout only contains a cmd window, which we would expect to
- occupy the entire terminal. But instead, the cmd window only occupies
- the first 8 lines, and the rest of the terminal is unused!
-
- The reason is, again, that the cmd window is keeping its previous
- size (8 lines).
-
- After this commit things are slightly different, the 'info win' output
- is now:
-
- (gdb) info win
- Name Lines Columns Focus
- cmd 20 80 (has focus)
-
- Which is a little better, but why only 20 lines? Turns out there's
- yet another bug hitting this case. That bug will be addressed in a
- later commit, so, for now, we're accepting the 20 lines.
-
- What this commit does is modify the phase of tui_layout_split::apply
- that handles any left over space. Usually, in "Step 2", each
- sub-layout has a size calculated. As the size is an integer, then,
- when all sizes are calculated we may have some space left over.
-
- This extra space is then distributed between all the windows fairly
- until all the space is used up.
-
- When we consider windows minimum size, or fixed size windows, then it
- is possible that we might try to use more space than is available,
- this was our first example above. The same code that added extra
- space to the windows, can also be used to reclaim space (in the over
- allocation case) to allow all windows to fit.
-
- The problem then is the cmd window, which we often force to a fixed
- size. Inside the loop that handles the allocation of excess space, if
- we find that we have tried every window, and still have space either
- left to give, or we need to claim back more space, then, if the cmd
- window was changed to a fixed size, we can change the cmd window back
- to a non-fixed-size window, and proceed to either give, or take space
- from the cmd window as needed.

-
- gdb/tui: fairer distribution of excess space during apply
- When applying layouts gdb computes the size of each window (or rather,
- each sub-layout within a layout) using integer arithmetic. As this
- rounds down the results, then, when all sub-layouts are sized, there
- is the possibility that we have some space left over.
-
- Currently, this space is just assigned to an arbitrary sub-layout.
-
- This can result in some unbalanced results. Consider this set of
- steps with current master:
-
- (gdb) tui enable
- (gdb) layout regs
- (gdb) info win
- Name Lines Columns Focus
- regs 7 80
- src 9 80 (has focus)
- status 1 80
- cmd 8 80
-
- Notice the weird split between the src and regs windows, the original
- layout specification has these windows given equal weight. The
- problem is that, with rounding, both the regs and src windows are
- initially sized to 7, the extra 2 lines are then arbitrarily added to
- the src window.
-
- In this commit, rather than add all the extra space to one single
- window, I instead hand out the extra space 1 line at a time, looping
- over all the sub-layouts. We take care to respect the min/max sizes,
- and so, we now get this result:
-
- (gdb) tui enable
- (gdb) layout regs
- (gdb) info win
- Name Lines Columns Focus
- regs 8 80
- src 8 80 (has focus)
- status 1 80
- cmd 8 80
-
- This looks more natural to me.
-
- This is obviously a change in behaviour, and so, lots of the existing
- tests need to be updated to take this into account. None of the
- changes are huge, it's just a line or two (or column for width) moved
- between windows.

- gdb/tui: avoid fp exception when applying layouts
- Consider:
-
- (gdb) tui enable
- (gdb) layout src
- (gdb) tui new-layout conly cmd 1
- (gdb) layout conly
-
- After this, with current master, gdb crashes with a floating-point
- exception.
-
- The problem is that in tui_layout_split::apply, when we switch from
- 'src' to 'conly', we will try to retain the cmd window height. As
- such, the cmd window will become a fixed size window, which decreases
- the available_size, but doesn't count towards the total_weight.
-
- As the cmd window is the only window, the total_weight stays at zero,
- and, when we move into step 2, where we attempt to size the windows,
- we perform a divide by zero, and crash.
-
- After this commit we avoid the divide by zero, and just directly set
- the window size based on the fixed size.
-
- There is still a problem after this commit, when the conly layout is
- selected the cmd window retains its original height, which will only
- be part of the terminal. The rest of the terminal is left unused.
- This issue will be addressed in a later commit, this commit is just
- about the floating-point exception.

- gdb/tui: add left_boxed_p and right_boxed_p member functions
- When I initially saw this code in tui_layout_split::apply, I assumed
- that this must be a bug:
-
- /* Two adjacent boxed windows will share a border, making a bit
- more size available. */
- if (i > 0
- && m_splits[i - 1].layout->bottom_boxed_p ()
- && m_splits[i].layout->top_boxed_p ())
- ...
-
- After all, the apply might be laying out a horizontal layout, right?
- So checking bottom_boxed_p and top_boxed_p is clearly wrong.
-
- Well, it turns on, that due to the implementations of these things,
- bottom_boxed_p is equivalent to an imagined right_boxed_p, and
- top_boxed_p is equivalent to an imagined left_boxed_p.
-
- In this commit I've renamed both top_boxed_p and bottom_boxed_p to
- first_edge_has_border_p and last_edge_has_border_p respectively, and
- extended the comments in tui_layout_base to mention that these methods
- handle both horizontal and vertical layouts.
-
- Now, hopefully, the code shouldn't look like it only applies for
- vertical layouts.

- gdb/tui: add a tui debugging flag
- This commit adds 'set debug tui on|off' and 'show debug tui'. This
- commit adds the control variable, and the printing macros in
- tui/tui.h. I've then added some uses of these in tui.c and
- tui-layout.c.
-
- To help produce more useful debug output in tui-layout.c, I've added
- some helper member functions in the class tui_layout_split, and also
- moved the size_info struct out of tui_layout_split::apply into the
- tui_layout_split class.
-
- If tui debug is not turned on, then there should be no user visible
- changes after this commit.
-
- One thing to note is that, due to the way that the tui terminal is
- often cleared, the only way I've found this useful is when I do:
-
- (gdb) tui enable
- (gdb) set logging file /path/to/file
- (gdb) set logging debugredirect on
- (gdb) set logging enable on
-
- Additionally, gdb has some quirks when it comes to setting up logging
- redirect and switching interpreters. Thus, the above only really
- works if the logging is enabled after the tui is enabled, and disabled
- again before the tui is disabled.
-
- Enabling logging and switching interpreters can cause undefined
- results, including crashes. This is an existing bug in gdb[1], and
- has nothing directly to do with tui debug, but it is worth mentioning
- here I think.

- gdb/tui: add new 'tui window width' command and 'winwidth' alias
- This commit adds a new command 'tui window width', and an alias
- 'winwidth'. This command is equivalent to the old 'winheight'
- command (which was recently renamed 'tui window height').
-
- Even though I recently moved the old tui commands under the tui
- namespace, and I would strongly encourage all new tui commands to be
- added as 'tui ....' only (users can create their own top-level aliases
- if they want), I'm breaking that suggestion here, and adding a
- 'winwidth' alias.
-
- Given that we already have 'winheight' and have done for years, it
- just didn't seem right to no have the matching 'winwidth'.
-
- You might notice in the test that the window resizing doesn't quite
- work right. I setup a horizontal layout, then grow and shrink the
- windows. At the end of the test the windows should be back to their
- original size...
-
- ... they are not. This isn't my fault, honest! GDB's window resizing
- is a little ... temperamental, and is prone to getting things slightly
- wrong during resizes, off by 1 type things. This is true for height
- resizing, as well as the new width resizing.
-
- Later patches in this series will rework the resizing algorithm, which
- should improve things in this area. For now, I'm happy that the width
- resizing is as good as the height resizing, given the existing quirks.
-
- For the docs side I include a paragraph that explains how multiple
- windows are required before the width can be adjusted. For
- completeness, I've added the same paragraph to the winheight
- description. With the predefined layouts this extra paragraph is not
- really needed for winheight, as there are always multiple windows on
- the screen. However, with custom layouts, this might not be true, so
- adding the paragraph seems like a good idea.
-
- As for the changes in gdb itself, I've mostly just taken the existing
- height adjustment code, changed the name to make it generic 'size'
- adjustment, and added a boolean flag to indicate if we are adjusting
- the width or the height.

- gdb/tui: rename tui_layout_split:set_weights_from_heights
- In a following commit I'm going to add the ability to change the width
- of a tui window (when in a horizontal layout). As a result, some of
- the places where we currently hard-code references to height need to
- be changed to handle either height, or width, based on whether we are
- in a vertical, or horizontal layout.
-
- This commit renames set_weights_from_heights to
- set_weights_from_sizes, and makes the function use either the height,
- or width as appropriate.
-
- Currently, the only place that we call this function is from the
- tui_layout_split::set_height function, in a part of the code we will
- only reach for vertical layouts, so the new code is not actually being
- used, but, this small change will help make later patches smaller, so
- I'm proposing this as a stand alone change.

- There should be no user visible changes after this commit.

- gdb: move some commands into the tui namespace
- There are a lot of tui related commands that live in the top-level
- command name space, e.g. layout, focus, refresh, winheight.
-
- Having them at the top level means less typing for the user, which is
- good, but, I think, makes command discovery harder.
-
- In this commit, I propose moving all of the above mentioned commands
- into the tui namespace, so 'layout' becomes 'tui layout', etc. But I
- will then add aliases so that the old commands will still work,
- e.g. I'll make 'layout' an alias for 'tui layout'.
-
- The benefit I see in this work is that tui related commands can be
- more easily discovered by typing 'tui ' and then tab-completing. Also
- the "official" command is now a tui-sub-command, this is visible in,
- for example, the help output, e.g.:
-
- (gdb) help layout
- tui layout, layout
- Change the layout of windows.
- Usage: tui layout prev | next | LAYOUT-NAME
-
- List of tui layout subcommands:
-
- tui layout asm -- Apply the "asm" layout.
- tui layout next -- Apply the next TUI layout.
- tui layout prev -- Apply the previous TUI layout.
- tui layout regs -- Apply the TUI register layout.
- tui layout split -- Apply the "split" layout.
- tui layout src -- Apply the "src" layout.
-
- Which I think is a good thing, it makes it clearer that this is a tui
- command.
-
- I've added a NEWS entry and updated the docs to mention the new and
- old command names, with the new name being mentioned first.

- I noticed that the CTF symbol reader passes the objfile's name to all

- compunit_symtabs created have the same name, that of the objfile:
-
- { objfile /tmp/babeltrace-ctf/src/lib/.libs/libbabeltrace2.so.0.0.0 ((struct objfile *) 0x613000005d00)

- }
- }
-
- Notice the two "name libbabeltrace2.so.0.0.0".
-
- Change it to pass the partial_symtab's filename instead. The output
- becomes:
-
- { objfile /tmp/babeltrace-ctf/src/lib/.libs/libbabeltrace2.so.0.0.0 ((struct objfile *) 0x613000005d00)

- linetable ((struct linetable *) 0x0)
- }
- }
-
- Note that the first compunit_symtab still has libbabeltrace2.so.0.0.0 as
- its name. This is because the CTF symbol reader really creates a
- partial symtab named like this. It appears to be because the debug info
- contains information that has been factored out of all CUs and is at the
- "top-level" of the objfile, outside any real CU. So it creates a
- partial symtab and an artificial CU that's named after the objfile.

- gdb/ctf: don't create a buildsym_compunit when building partial symbols
- I am trying to do some changes to buildsym_compunit, so I am auditing
- the current uses. Something seems odd with this use of
- buildsym_compunit (that this patch removes).
-
- A buildsym_compunit is normally used when building a compunit_symtab.
- That is, when expanding a partial symtab into a full compunit symtab.
- In ctfread.c, a buildsym_compunit is created in ctf_start_archive, which
- is only used when creating partial symtabs. At this moment, I don't
- see how that's useful. ctf_start_archive creates a new
- buildsym_compunit and starts a subfile. But that buildsym_compunit is
- never used again. It's just overriden in ctf_start_symtab, which means
- we leak the old buildsym_compunit, I suppose.
-
- Remove ctf_start_archive completely. Add an assert in
- ctf_start_symtab to verify that we are not overwriting an existing
- buildsym_compunit (meaning we'd leak the existing one). This assert
- triggers without the other part of the fix. When doing:
-
- $ ./gdb --data-directory=data-directory /tmp/babeltrace-ctf/src/lib/.libs/libbabeltrace2.so.0.0.0
- ...
- (gdb) maintenance expand-symtabs
- /home/simark/src/binutils-gdb/gdb/ctfread.c:1255: internal-error: ctf_start_symtab: Assertion `!ccp->builder' failed.

- Style URLs in GDB output
- I noticed that GDB will display URLs in a few spots. This changes
- them to be styled. Originally I thought I'd introduce a new "url"
- style, but there aren't many places to use this, so I just reused
- filename styling instead. This patch also changes the debuginfod URL
- list to be printed one URL per line. I think this is probably a bit
- easier to read.

- gdb: initialize ctf_context::builder in create_partial_symtab
- I built a random project with -gctf, in order to test the CTF support in
- GDB. With my ASan/UBSan/etc-enabled build of GDB, I get:
-
- $ ./gdb --data-directory=data-directory /tmp/babeltrace-ctf/src/lib/.libs/libbabeltrace2.so.0.0.0
- ...
- Reading symbols from /tmp/babeltrace-ctf/src/lib/.libs/libbabeltrace2.so.0.0.0...
- /home/simark/src/binutils-gdb/gdb/ctfread.c:1545:31: runtime error: member call on misaligned address 0xbebebebebebebebe for type 'struct buildsym_compunit', which requires 8 byte alignment
- 0xbebebebebebebebe: note: pointer points here
-
- The 0xbebebebebebebebe value is a sign that the ctf_context::builder
- field is uninitialized. The problem probably goes under the radar if
- the field happens to be zero-initialized, because ctf_start_archive
- contains this code:
-
- if (ccx->builder == nullptr)
- {
- ccx->builder = new buildsym_compunit (of,
- of->original_name, nullptr, language_c, 0);
-
- If the field was zero-initialized (by chance), this will create a new
- buildsym_compunit. But if the field was purposely filled with random
- bytes by one of the sanitizers, we won't create a buildsym_compunit here
- and we'll continue with ccx->builder equal to 0xbebebebebebebebe.
-
- Fix this the easy way by initializing ccx->builder where the other
- ctf_context fields are initialized (yeah, this code could be made nicer
- C++, but I am going for the obvious fix here).
-
- With this patch, this passes cleanly on my system:
-
- $ make check TESTS="gdb.ctf/*.exp" RUNTESTFLAGS="CC_FOR_TARGET=/opt/gcc/git/bin/gcc"
- # of expected passes 40
-
- ... where /opt/gcc/git/bin/gcc is a gcc with CTF support, given my
- system gcc does not have it.

- gdb/linux-nat: remove check based on current_inferior in linux_handle_extended_wait
- The check removed by this patch, using current_inferior, looks wrong.
- When debugging multiple inferiors with the Linux native target and
- linux_handle_extended_wait is called, there's no guarantee about which
- is the current inferior. The vfork-done event we receive could be for
- any inferior. If the vfork-done event is for a non-current inferior, we
- end up wrongfully ignoring it. As a result, the core never processes a
- TARGET_WAITKIND_VFORK_DONE event, program_space::breakpoints_not_allowed
- is never cleared, and breakpoints are never reinserted. However,
- because the Linux native target decided to ignore the event, it resumed
- the thread - while breakpoints out. And that's bad.
-
- The proposed fix is to remove this check. Always report vfork-done
- events and let infrun's logic decide if it should be ignored. We don't
- save much cycles by filtering the event here.
-
- Add a test that replicates the situation described above. See comments
- in the test for more details.

- gdbserver/linux: set lwp !stopped when failing to resume
- I see some failures, at least in gdb.multi/multi-re-run.exp and
- gdb.threads/interrupted-hand-call.exp. Running `stress -C $(nproc)` at
- the same time as the test makes those tests relatively frequent.
-
- Let's take gdb.multi/multi-re-run.exp as an example. The failure looks
- like this, an unexpected "no resumed":
-
- continue
- Continuing.
- No unwaited-for children left.
- (gdb) FAIL: gdb.multi/multi-re-run.exp: re_run_inf=2: iter=1: continue until exit
-
- The situation is:
-
- - Inferior 1 is stopped somewhere, it won't really play a role here.
- - Inferior 2 has 2 threads, both stopped.
- - We resume inferior 2, the leader thread is expected to exit, making
- the process exit.

-
- What happens is:
-
- - We resume the leader (713935) successfully.
- - The leader exits.
- - We resume the secondary thread (713936), we get ESRCH. This is
- expected this the leader has exited.
- - resume_one_lwp_throw throws, it's caught by resume_one_lwp.
- - resume_one_lwp checks with check_ptrace_stopped_lwp_gone that the
- failure can be explained by the LWP becoming zombie, and swallows the
- error.
- - Note that this means that the secondary lwp still has stopped==1.
- - wait_1 is called, probably because linux_process_target::resume marks
- the async pipe at the end.
- - The exit event isn't ready yet, probably because the machine is under
- load, so waitpid returns nothing.
- - check_zombie_leaders detects that the leader is zombie and deletes
- - We try to find a resumed (non-stopped) LWP to get an event from,
- there's none since the leader (that was resumed) is now deleted, and
- the secondary thread is still marked stopped.
- wait_for_event_filtered returns -1, causing wait_1 to return
- NO_RESUMED.
-
- What I notice here is that there is some kind of race between the
- availability of the process' exit notification and the call to wait_1
- that results from marking the async pipe at the end of resume.
-
- I think what we want from this wait_1 invocation is to keep waiting, as
- we will eventually get thread exit notifications for both of our
- threads.
-
- The fix I came up with is to mark the secondary thread as !stopped (or
- resumed) when we fail to resume it. This makes wait_1 see that there is
- at least one resume lwp, so it won't return NO_RESUMED. I think this
- makes sense to consider it resumed, because we are going to receive an
- exit event for it. Here's the GDBserver logs with the fix applied:

- gdb: test vfork + follow-fork-mode=parent + detach-on-fork=off
- The particular behavior we have when using that combination of settings
- doesn't seem tested at all (at least, I don't find it if I grep for "Can
- not resume the parent process"). Add a simple test for that.

- gdb/testsuite: add tests for Term
- While trying to review Andrew's patch here [1], I thought I spotted a
- bug in the handling of a CSI, but I had no way to know for sure. So I
- thought it would be useful to have unit tests for the handling of
- control characters and control sequences of our toy terminal
- implementation. It might help avoid chasing bugs in the GDB TUI when in
- reality it's a problem with the testsuite's terminal implementation.
-
- Add the gdb.tui/tuiterm.exp file to do that. All currently supported
- control sequences and characters are tested, except _csi_m (the one that
- handles colors and stuff). _csi_m should probably be tested too, but it
- will require more work.
-
- Fix a few issues that the tests spotted:
-
- - backspace: according to [3] (table 4-1), a backspace when the cursor
- is at the beginning of a line should have no effect. Our
- implementation did wrap to the end of the previous line. Change our
- implementation to match the doc (and the test).
- - insert character: this control sequence is supposed to insert blank
- characters, shifting all the rest of the line right. The current
- implementation moves N characters right, but it overwrites the
- characters on the right instead of shifting them. It also doesn't
- insert blank characters at the cursor.
- - Cursor down, forward, next line: off-by-one error when reaching the
- end of the display.
- - erase in display, line: off-by-one errors.
- - vertical line position absolute: allowed setting the cursor outside
- the display, when it should clamp it to the display size.
-
- I found that this web page [2] gave some good clues on the expected
- behavior of some control characters or sequences that some other pages
- didn't.

- Only allow QUIT on the main thread
- Pedro pointed out that gdb worker threads should not react to quits.
- While I don't think that the new DWARF reader can call QUIT from a
- worker thread (and I don't think the existing minsym threading code
- can either), it seems safest to address this before checking in the
- new code. This patch arranges for the QUIT macro to only work on the
- main thread.

- Use gdb_printf and gdb_vprintf in more places
- Luis pointed out that I missed a spot in the gdb_printf conversion --
- namely aarch64-nat.c. While looking at this, I found another spot in
- darwin-nat.c that I also missed. I can't build either of these, but I
- think this patch should fix the problems.
-
- Consolidate definition of current_directory
- I noticed that both gdbserver and gdb define current_directory.
- However, as it is referenced by gdbsupport, it seemed better to define
- it there as well. This patch also moves the declaration to
- pathstuff.h. Tested by rebuilding.

- Decode "dynamic" interface types in Ada
- In Ada, if a class implements an interface and has a dynamic
- superclass, then the "offset to top" -- the offset that says how to
- turn a pointer to the interface into a pointer to the whole object --
- is stored in the object itself. This patch changes GDB to understand
- this.
-
- Because this only touches Ada code, and because Joel already reviewed
- it internally, I am checking it in.

-
- Remove unnecessary calls to wrap_here and gdb_flush
- Various spots in gdb currently know about the wrap buffer, and so are
- careful to call wrap_here to be certain that all output has been
- flushed.
-
- Now that the pager is just an ordinary stream, this isn't needed, and
- a simple call to gdb_flush is enough.
-
- Similarly, there are places where gdb prints to gdb_stderr, but first
- flushes gdb_stdout. stderr_file already flushes gdb_stdout, so these
- aren't needed.

-
- Minor comment updates in utils.h
- This patch updates some comments in utils.h to more closely reflect
- the new reality.
-
- Remove vfprintf_styled
- Nothing calls vfprintf_styled any more, so remove it.
-
- Remove ui_out_flag::unfiltered_output
- There is no longer any need for ui_out_flag::unfiltered_output --
- nothing ever sets this flag. This used to be needed to make the
- _unfiltered output work, but now only printf_unfiltered can be used,
- and it uses the puts_unfiltered method. This patch removes the flag
- and the dead code.
-
- Rename fprintf_symbol_filtered
- fprintf_symbol_filtered is misnamed, because whether filtering happens
- is now up to the stream. This renames it to fprintf_symbol, which
- isn't a great name (the first "f" doesn't mean much and the second one
- is truly meaningless here), but "print_symbol" was already taken.
-
- Rename puts_filtered_tabular
- puts_filtered_tabular is now misnamed, because whether filtering
- happens is now up to the stream. So, rename it. (This function is
- pretty weird, and should probably be rewritten to avoid using the
- chars_printed global, and moved into objc-lang.c. However, I haven't
- done so.)
-
- Rename print_spaces_filtered
- print_spaces_filtered is now misnamed, because whether filtering
- happens is up to the stream. So, rename it.
-
- Unify gdb printf functions
- Now that filtered and unfiltered output can be treated identically, we
- can unify the printf family of functions. This is done under the name
- "gdb_printf". Most of this patch was written by script.
-
- Unify gdb putc functions
- Now that filtered and unfiltered output can be treated identically, we
- can unify the putc family of functions. This is done under the name
- "gdb_putc". Most of this patch was written by script.
-
- Unify gdb puts functions
- Now that filtered and unfiltered output can be treated identically, we
- can unify the puts family of functions. This is done under the name
- "gdb_puts". Most of this patch was written by script.
-
- Unify vprintf functions
- Now that filtered and unfiltered output can be treated identically, we
- can unify the vprintf family of functions: vprintf_filtered,
- vprintf_unfiltered, vfprintf_filtered and vfprintf_unfiltered. (For
- the gdb_stdout variants, recall that only printf_unfiltered gets truly
- unfiltered output at this point.) This removes one such function and
- renames the remaining two to "gdb_vprintf". All callers are updated.
- Much of this patch was written by script.
-
- Remove fputs_styled_unfiltered
- fputs_styled_unfiltered is only called from cli_ui_out, so remove it.
- This area will be further simplified in future patches.

-
- Change the pager to a ui_file
- This rewrites the output pager as a ui_file implementation.
-
- A new header is introduced to declare the pager class. The
- implementation remains in utils.c for the time being, because there
- are some static globals there that must be used by this code. (This
- could be cleaned up at some future date.)
-
- I went through all the text output in gdb to ensure that this change
- should be ok. There are a few cases:
-
- * Any existing call to printf_unfiltered is required to be avoid the
- pager. This is ensured directly in the implementation.
-
- * All remaining calls to the f*_unfiltered functions -- the ones that
- take an explicit ui_file -- either send to an unfiltered stream
- (e.g., gdb_stderr), which is obviously ok; or conditionally send to
- gdb_stdout
-
- I investigated all such calls by searching for:
-
- grep -e '\bf[a-z0-9_]*_unfiltered' *.[chyl] */*.[ch] | grep -v gdb_stdlog | grep -v gdb_stderr
-
- This yields a number of candidates to check.
-
- * The breakpoint _print_recreate family, and
- save_trace_state_variables. These are used for "save" commands
- and so are fine.
-
- * Things printing to a temporary stream. Obviously ok.
-
- * Disassembly selftests.
-
- * print_gdb_help - this is non-obvious, but ok because paging isn't
- yet enabled at this point during startup.
-
- * serial.c - doens't use gdb_stdout
-
- * The code in compile/. This is all printing to a file.
-
- * DWARF DIE dumping - doesn't reference gdb_stdout.
-
- * Calls to the _filtered form -- these are all clearly ok, because if
- they are using gdb_stdout, then filtering will still apply; and if
- not, then filtering never applied and still will not.
-
- Therefore, at this point, there is no longer any distinction between
- all the other _filtered and _unfiltered calls, and they can be
- unified.
-
- In this patch, take special note of the vfprintf_maybe_filtered and
- ui_file::vprintf change. This is one instance of the above idea,
- erasing the distinction between filtered and unfiltered -- in this
- part of the change, the "unfiltered_output" flag is never passe to
- cli_ui_out. Subsequent patches will go much further in this
- direction.
-
- Also note the can_emit_style_escape changes in ui-file.c. Checking
- against gdb_stdout or gdb_stderr was always a bit of a hack; and now
- it is no longer needed, because this is decision can be more fully
- delegated to the particular ui_file implementation.
-
- ui_file::can_page is removed, because this patch removed the only call
- to it.
-
- I think this is the main part of fixing PR cli/7234.

-
- Remove vfprintf_styled_no_gdbfmt
- This removes vfprintf_styled_no_gdbfmt, inlining it at the sole point
- of call.
-
- Add style-escape methods to ui_file
- This adds emit_style_escape and reset_style methods to ui_file. These
- aren't used yet, but they will be once the pager is converted to be a
- ui_file subclass.
-
- Add puts_unfiltered method to ui_file
- When the pager is rewritten as a ui_file, gdb will still need a way to
- bypass the filtering. After examining a few approaches, I chose this
- patch, which adds a puts_unfiltered method to ui_file. For most
- implementations of ui_file, this will just delegate to puts. This
- patch also switches printf_unfiltered to use the new method.
-
- Only have one API for unfiltered output
- At the end of this series, the use of unfiltered output will be very
- restricted -- only places that definitely need it will use it. To
- this end, I thought it would be good to reduce the number of
- _unfiltered APIs that are exposed. This patch changes gdb so that
- only printf_unfiltered exists. (After this patch, the f* variants
- still exist as well, but those will be removed later.)
-
-2022-03-29 Tom Tromey <tom@tromey.com>
-
- Remove some uses of printf_unfiltered
- A number of spots call printf_unfiltered only because they are in code
- that should not be interrupted by the pager. However, I believe these
- cases are all handled by infrun's blanket ban on paging, and so can be
- converted to the default (_filtered) API.
-
- After this patch, I think all the remaining _unfiltered calls are ones
- that really ought to be. A few -- namely in complete_command -- could
- be replaced by a scoped assignment to pagination_enabled, but for the
- remainder, the code seems simple enough like this.
-
-2022-03-29 Tom Tromey <tom@tromey.com>
-
- Use unfiltered output in annotate.c
- It seems to me that annotations should not be filtered. While it
- might be weird for an annotation-based UI to use the pager, it's not,
- I think, out of the question. This patch makes this change.

- gdb/remote: use current_inferior in read_ptid if multi-process not supported
- When parsing the ptid out of a reply package, if the multi-process
- extensions are not supported, use current_inferior's pid as the pid of
- the reported thread, instead of inferior_ptid. This is needed because
- the inferior_ptid may be null_ptid although a legit context exists,
- due to a prior context switch via switch_to_inferior_no_thread.
-
- Below is a scenario that illustrates what could go wrong. First,
- setup a multi-target scenario. This is needed, because in a
- multi-target setting, the inferior_ptid is cleared out before waiting
- on targets. The second inferior below sits on top of a remote target.
- Multi-process packets are disabled.

- gdb/testsuite: fix test failure when building against readline v7
- The test added in the commit:
-
- commit a6b413d24ccc5d76179bab866834e11fd6fec294
- Date: Fri Mar 11 14:44:03 2022 +0000
-
- gdb: work around prompt corruption caused by bracketed-paste-mode
-
- Was not written with readline 7 in mind, only readline 8+. Between
- readline 7 and 8 the escape sequence used to disable bracketed paste
- mode changed, an additional '\r' character was added to the end. In
- fact, it was the addition of this '\r' character that triggered the
- issue for which the above commit is part of the solution.
-
- Anyway, the test tries to spot the case where the output from GDB is
- not perfect, but does have the above work around applied. However,
- the pattern in the test assumes that the problematic '\r' will be
- present, and this is only true for readline 8+. With readline 7 the
- test was failing.
-
- In this commit I generalise the pattern a little so that the test will
- still KFAIL with readline 7.
-
- It's a little unfortunate that the test is KFAILing with readline 7,
- as without the problematic '\r' there's actually no reason that GDB
- couldn't "do the right thing" in this case, in which case, the test
- would PASS, but that would require changes within GDB itself.
-
- My preference then is that initially we patch the test to get it
- KFAILing, then in a separate commit I can modify GDB so that it can
- PASS with readline 7.

- gdb/testsuite: fix copy & paste error in gdb.python/py-format-address.exp
- The test gdb.python/py-format-address.exp, added in commit:
-
- commit 25209e2c6979c3838e14e099f0333609810db280
- Date: Sat Oct 23 09:59:25 2021 +0100
-
- gdb/python: add gdb.format_address function
-
- included 3 copy & paste errors where the wrong address was used in the
- expected output patterns.
-
- The test compiles two almost identical test binaries (one function
- changes its name, that's the only difference), two inferiors are
- created, each inferior using one of the test binaries.
-
- We then take the address of the name changing function in both
- inferiors ('foo' in inferior 1 and 'bar' in inferior 2) and the tests
- are carried out using these addresses.
-
- What we're checking for is that symbols 'foo' and 'bar' show up in the
- correct inferior, and that (as this test is for a Python API feature),
- the user can have one inferior selected, but ask about the other
- inferior, and see the correct symbol in the result.
-
- The hope is that the two binaries will be laid out identically by the
- compiler, and that 'foo' and 'bar' will be at the same address. This
- is fine, unless the executable is compiled as PIE (position
- independent executable), in which case there is a problem.
-
- The problem is that though inferior 1 is set running, the inferior 2
- never is. If the executables are compiled as PIE, then the address in
- the inferior 2 will not have been resolved, while the address in the
- inferior 1 will have been, and so the two addresses we use in the
- tests will be different.
-
- This issue was reported here:
-
- https://sourceware.org/pipermail/gdb-patches/2022-March/186911.html
-
- The first part of the fix is to use the correct address variable in
- the expected output patterns, with this change the tests pass even
- when the executables are compiled as PIE.
-
- A second part of this fix is to pass the 'nopie' option when we
- compile the tests, this should ensure that the address obtained in
- inferior 2 is the same as the address from inferior 1, which makes the
- test more useful.

- gdb/mi: fix use after free of frame_info causing spurious notifications
- In commit:
-
- commit a2757c4ed693cef4ecc4dcdcb2518353eb6b3c3f
- Date: Wed Mar 16 15:08:22 2022 +0000
-
- gdb/mi: consistently notify user when GDB/MI client uses -thread-select
-
- Changes were made to GDB to address some inconsistencies in when
- notifications are sent from a MI terminal to a CLI terminal (when
- multiple terminals are in use, see new-ui command).
-
- Unfortunately, in order to track when the currently selected frame has
- changed, that commit grabs a frame_info pointer before and after an MI
- command has executed, and compares the pointers to see if the frame
- has changed.
-
- This is not safe.
-
- If the frame cache is deleted for any reason then the frame_info
- pointer captured before the command started, is no longer valid, and
- any comparisons based on that pointer are undefined.
-
- This was leading to random test failures for some folk, see:
-
- https://sourceware.org/pipermail/gdb-patches/2022-March/186867.html
-
- This commit changes GDB so we no longer hold frame_info pointers, but
- instead store the frame_id and frame_level, this is safe even when the
- frame cache is flushed.

- bfd/Dwarf2: gas doesn't mangle names
- Include the language identifier emitted by gas in the set of ones where
- no mangled names are expected. Even if there could be "hand-mangled"
- names, gas doesn't emit DW_AT_linkage_name in the first place.
-
- bfd/Dwarf2: make find-nearest-line returned function name consistent
- Prior to entering the enclosing "else if()" the earlier associated if()
- checks function->is_linkage and, if set, uses function->name. The
- comment in patch context precedes (and explains) the setting
- function->is_linkage. Yet with the flag set, we should then also return
- the function name, just like said earlier if() would do when we came
- here a 2nd time for the same "addr". And indeed passing the same address
- twice on addr2line's command line would resolve the function for the 2nd
- instance, but not for the 1st (if this code path is taken). (This,
- obviously, is particularly relevant when there's no ELF symbol table in
- the first place, like would be the case - naturally - in PE/COFF
- binaries, for example.)
-
- gas/Dwarf: special-case .linefile only for macros
- Restrict the PR gas/16908 workaround to just macros, matching the
- original intention as well as the comment there. For constructs like
- .irp or .rept the reasoning doesn't apply, as there's no separate
- "invocation" point which may be of interest to record (for, as said
- there, short macros).

- RISC-V: correct FCVT.Q.L[U]
- While the spec isn't explicit about this, it pointing out the similarity

- rounding mode: "Note FCVT.D.W[U] always produces an exact result and is
- unaffected by rounding mode." Hence the chosen encodings also ought to

- Note that to avoid breaking existing code the forms with a 3rd operand
- are not removed, which means there continues to be a difference to

- Switch gdb_stdlog to use timestamped_file
- Currently, timestamps for logging are done by looking for the use of
- gdb_stdlog in vfprintf_unfiltered. This seems potentially buggy, in
- that during logging or other redirects (like execute_fn_to_ui_file) we
- might have gdb_stdout==gdb_stdlog and so, conceivably, wind up with
- timestamps in a log when they were not desired.
-
- It seems better, instead, for timestamps to be a property of the
- ui_file itself.
-
- This patch changes gdb to use the new timestamped_file for gdb_stdlog
- where appropriate, and removes the special case from
- vfprintf_unfiltered.
-
- Note that this may somewhat change the output in some cases -- in
- particular, when going through execute_fn_to_ui_file (or the _string
- variant), timestamps won't be emitted. This could be fixed in those
- functions, but it wasn't clear to me whether this is really desirable.
-
- Note also that this changes the TUI to send gdb_stdlog to gdb_stderr.
- I imagine that the previous use of gdb_stdout here was inadvertent.
- (And in any case it probably doesn't matter.)

- The new class is not yet used.

- Simplify the CLI set_logging logic
- The CLI's set_logging logic seemed unnecessarily complicated to me.
- This patch simplifies it, with an eye toward changing it to use RAII
- objects in a subsequent patch.
-
- I did not touch the corresponding MI code. That code seems incorrect
- (nothing ever uses raw_stdlog, and nothing ever sets
- saved_raw_stdlog). I didn't attempt to fix this, because I question
- whether this is even useful for MI.

- Handle multiple addresses in call_site_target
- A large customer program has a function that is partitioned into hot
- and cold parts. A variable in a callee of this function is described
- using DW_OP_GNU_entry_value, but gdb gets confused when trying to find
- the caller. I tracked this down to dwarf2_get_pc_bounds interpreting
- the function's changes so that the returned low PC is the "wrong"
- function.
-
- Intead, when processing DW_TAG_call_site, the low PC of each range in
- DW_AT_ranges should be preserved in the call_site_target. This fixes
- the variable lookup in the test case I have.
-
- I didn't write a standalone test for this as it seemed excessively
- complicated.

-
- Change call_site_target to iterate over addresses
- In order to handle the case where a call site target might refer to

- that may be called multiple times.

-
- Change call_site_find_chain_1 to work recursively
- call_site_find_chain_1 has a comment claiming that recursive calls
- would be too expensive. However, I doubt this is so expensive; and
- furthermore the explicit state management approach here is difficult
- both to understand and to modify. This patch changes this code to use
- explicit recursion, so that a subsequent patch can generalize this
- code without undue trauma.
-
- Additionally, I think this patch detects a latent bug in the recursion
- code. (It's hard for me to be completely certain.) The bug is that
- when a new target_call_site is entered, the code does:
-
- if (target_call_site)
- {
- if (addr_hash.insert (target_call_site->pc ()).second)
- {
- /* Successfully entered TARGET_CALL_SITE. */
-
- chain.push_back (target_call_site);
- break;
- }
- }
-
- Here, if entering the target_call_site fails, then any tail_call_next
- elements in this call site are not visited. However, if this code
- does happen to enter a call site, then the tail_call_next elements
- will be visited during backtracking. This applies when doing the
- backtracking as well -- it will only continue through a given chain as
- long as each element in the chain can successfully be visited.
-
- I'd appreciate some review of this. If this behavior is intentional,
- it can be added to the new implementation.
-

-
- Constify chain_candidate
- While investigating this bug, I wasn't sure if chain_candidate might
- update 'chain'. I changed it to accept a const reference, making it
- clear that it cannot. This simplifies the code a tiny bit as well.
-
- Make call_site_target members private
- This makes the data members of call_site_target 'private'. This lets
- us remove most of its public API. call_site_to_target_addr is changed
- to be a method of this type. This is a preparatory refactoring for
- the fix at the end of this series.
-
- Change call_site_target to use custom type and enum
- call_site_target reuses field_loc_kind and field_location. However,
- it has never used the full range of the field_loc_kind enum. In a
- subsequent patch, I plan to add a new 'kind' here, so it seemed best
- to avoid this reuse and instead introduce new types here.

- libtool.m4: fix the NM="/nm/over/here -B/option/with/path" case
- My previous nm patch handled all cases but one -- if the user set NM in
- the environment to a path which contained an option, libtool's nm
- detection tries to run nm against a copy of nm with the options in it:
- e.g. if NM was set to "nm --blargle", and nm was found in /usr/bin, the
- test would try to run "/usr/bin/nm --blargle /usr/bin/nm --blargle".
- This is unlikely to be desirable: in this case we should run
- "/usr/bin/nm --blargle /usr/bin/nm".
-
- Furthermore, as part of this nm has to detect when the passed-in $NM
- contains a path, and in that case avoid doing a path search itself.
- This too was thrown off if an option contained something that looked
- like a path, e.g. NM="nm -B../prev-gcc"; libtool then tries to run
- "nm -B../prev-gcc nm" which rarely works well (and indeed it looks
- to see whether that nm exists, finds it doesn't, and wrongly concludes
- that nm -p or whatever does not work).
-
- Fix all of these by clipping all options (defined as everything
- including and after the first " -") before deciding whether nm
- contains a path (but not using the clipped value for anything else),
- and then removing all options from the path-modified nm before
- looking to see whether that nm existed.
-
- NM=my-nm now does a path search and runs e.g.
- /usr/bin/my-nm -B /usr/bin/my-nm
-
- NM=/usr/bin/my-nm now avoids a path search and runs e.g.
- /usr/bin/my-nm -B /usr/bin/my-nm
-
- NM="my-nm -p../wombat" now does a path search and runs e.g.
- /usr/bin/my-nm -p../wombat -B /usr/bin/my-nm
-
- NM="../prev-binutils/new-nm -B../prev-gcc" now avoids a path search:
- ../prev-binutils/my-nm -B../prev-gcc -B ../prev-binutils/my-nm
-
- This seems to be all combinations, including those used by GCC bootstrap
- (which, before this commit, fails to bootstrap when configured
- --with-build-config=bootstrap-lto, because the lto plugin is now using
- --export-symbols-regex, which requires libtool to find a working nm,
- while also using -B../prev-gcc to point at the lto plugin associated
- with the GCC just built.)
-
- Regenerate all affected configure scripts.
-
- * libtool.m4 (LT_PATH_NM): Handle user-specified NM with
- options, including options containing paths.

- Remove download size from debuginfod progress messages if unavailable
- Currently debuginfod progress update messages include the size of

- Downloading 7.5 MB separate debug info for /lib/libxyz.so.0

- This value originates from the Content-Length HTTP header of the

-
- gdb/testsuite: relax pattern in new gdb.mi/mi-multi-commands.exp test
-
- The second of these commits was intended to address periodic test
- failures that I was seeing, and this change did fix some problems,
- but, unfortunately, introduced other issues.
-
- The problem is that the test relies on sending two commands to GDB in
- a single write. As the characters that make these two commands arrive
- they are echoed to GDB's console. However, there is a race between
- how quickly the characters are echoed and how quickly GDB decides to
- act on the incoming commands.
-
- Usually, both commands are echoed in full before GDB acts on the first
- command, but sometimes this is not the case, and GDB can execute the
- first command before both commands are fully echoed to the console.
- In this case, the output of the first command will be mixed in with
- the echoing of the second command.
-
- This mixing of the command echoing and the first command output is
- what was causing failures in the original version of the test.
-
- The second commit relaxed the expected output pattern a little, but
- was still susceptible to failures, so this commit further relaxes the
- pattern.
-
- Now, we look for the first command output with no regard to what is
- before, or after the command. Then we look for the first mi prompt to
- indicate that the first command has completed.
-
- I believe that this change should make the test more stable than it
- was before.

- libctf: add LIBCTF_WRITE_FOREIGN_ENDIAN debugging option
- libctf has always handled endianness differences by detecting
- foreign-endian CTF dicts on the input and endian-flipping them: dicts
- are always written in native endianness. This makes endian-awareness
- very low overhead, but it means that the foreign-endian code paths
- almost never get routinely tested, since "make check" usually reads in
- dicts ld has just written out: only a few corrupted-CTF tests are
- actually in fixed endianness, and even they only test the foreign-
- endian code paths when you run make check on a big-endian machine.
- (And the fix is surely not to add more .s-based tests like that, because
- they are a nightmare to maintain compared to the C-code-based ones.)
-
- To improve on this, add a new environment variable,
- LIBCTF_WRITE_FOREIGN_ENDIAN, which causes libctf to unconditionally
- endian-flip at ctf_write time, so the output is always in the wrong
- endianness. This then tests the foreign-endian read paths properly
- at open time.
-
- Make this easier by restructuring the writeout code in ctf-serialize.c,
- which duplicates the maybe-gzip-and-write-out code three times (once
- for ctf_write_mem, with thresholding, and once each for
- ctf_compress_write and ctf_write just so those can avoid thresholding
- and/or compression). Instead, have the latter two call the former
- with thresholds of 0 or (size_t) -1, respectively.
-
- The endian-flipping code itself gains a bit of complexity, because
- one single endian-flipper (flip_types) was assuming the input to be
- in foreign-endian form and assuming it could pull things out of the
- input once they had been flipped and make sense of them. At the
- cost of a few lines of duplicated initializations, teach it to
- read before flipping if we're flipping to foreign-endianness instead
- of away from it.

- libctf, ld: diagnose corrupted CTF header cth_strlen
- The last section in a CTF dict is the string table, at an offset
- represented by the cth_stroff header field. Its length is recorded in
- the next field, cth_strlen, and the two added together are taken as the
- size of the CTF dict. Upon opening a dict, we check that none of the
- header offsets exceed this size, and we check when uncompressing a
- compressed dict that the result of the uncompression is the same length:
- but CTF dicts need not be compressed, and short ones are not.
- Uncompressed dicts just use the ctf_size without checking it. This
- field is thankfully almost unused: it is mostly used when reserializing
- a dict, which can't be done to dicts read off disk since they're
- read-only.
-
- However, when opening an uncompressed foreign-endian dict we have to
- copy it out of the mmaped region it is stored in so we can endian-
- swap it, and we use ctf_size when doing that. When the cth_strlen is
- corrupt, this can overrun.
-
- Fix this by checking the ctf_size in all uncompressed cases, just as we
- already do in the compressed case. Add a new test.
-
- This came to light because various corrupted-CTF raw-asm tests had an
- incorrect cth_strlen: fix all of them so they produce the expected
- error again.

- include, libctf, ld: extend variable section to contain functions too
- The CTF variable section is an optional (usually-not-present) section in
- the CTF dict which contains name -> type mappings corresponding to data
- symbols that are present in the linker input but not in the output
- symbol table: the idea is that programs that use their own symbol-
- resolution mechanisms can use this section to look up the types of
- symbols they have found using their own mechanism.
-
- Because these removed symbols (mostly static variables, functions, etc)
- all have names that are unlikely to appear in the ELF symtab and because
- very few programs have their own symbol-resolution mechanisms, a special
- linker flag (--ctf-variables) is needed to emit this section.
-
- Historically, we emitted only removed data symbols into the variable
- section. This seemed to make sense at the time, but in hindsight it
- really doesn't: functions are symbols too, and a C program can look them
- up just like any other type. So extend the variable section so that it
- contains all static function symbols too (if it is emitted at all), with
- types of kind CTF_K_FUNCTION.
-
- This is a little fiddly. We relied on compiler assistance for data
- symbols: the compiler simply emits all data symbols twice, once into the
- symtypetab as an indexed symbol and once into the variable section.
-
- Rather than wait for a suitably adjusted compiler that does the same for
- function symbols, we can pluck unreported function symbols out of the
- symtab and add them to the variable section ourselves. While we're at
- it, we do the same with data symbols: this is redundant right now
- because the compiler does it, but it costs very little time and lets the
- compiler drop this kludge and save a little space in .o files.

- ld, testsuite: improve CTF-availability test
- The test for -gctf support in the compiler is used to determine when to
- run the ld-ctf tests and most of those in libctf. Unfortunately,
- because it uses check_compiler_available and compile_one_cc, it will
- fail whenever the compiler emits anything on stderr, even if it
- actually does support CTF perfectly well.
-
- So, instead, ask the compiler to emit assembler output and grep it for
- references to ".ctf": this is highly unlikely to be present if the
- compiler does not support CTF. (This will need adjusting when CTF grows
- support for non-ELF platforms that don't dot-prepend their section
- names, but right now the linker doesn't link CTF on any such platforms
- in any case.)
-
- With this in place we can do things like run all the libctf tests under
- leak sanitizers etc even if those spray warnings on simple CTF
- compilations, rather than being blocked from doing so just when we would
- most like to.
-

- gdb/python: remove Python 2 support
- New in this version:
-
- - Add a PY_MAJOR_VERSION check in configure.ac / AC_TRY_LIBPYTHON. If
- the user passes --with-python=python2, this will cause a configure
- failure saying that GDB only supports Python 3.
-
- Support for Python 2 is a maintenance burden for any patches touching
- Python support. Among others, the differences between Python 2 and 3
- string and integer types are subtle. It requires a lot of effort and
- thinking to get something that behaves correctly on both. And that's if
- the author and reviewer of the patch even remember to test with Python
- 2.
-
- See this thread for an example:
-
- https://sourceware.org/pipermail/gdb-patches/2021-December/184260.html
-
- So, remove Python 2 support. Update the documentation to state that GDB
- can be built against Python 3 (as opposed to Python 2 or 3).
-
- Update all the spots that use:
-
- - sys.version_info
- - IS_PY3K
- - PY_MAJOR_VERSION
- - gdb_py_is_py3k
-
- ... to only keep the Python 3 portions and drop the use of some
- now-removed compatibility macros.
-
- I did not update the configure script more than just removing the
- explicit references to Python 2. We could maybe do more there, like
- check the Python version and reject it if that version is not
- supported. Otherwise (with this patch), things will only fail at
- compile time, so it won't really be clear to the user that they are
- trying to use an unsupported Python version. But I'm a bit lost in the
- configure code that checks for Python, so I kept that for later.

-
- Perhaps right from its introduction in 4d1bb7955a8b it was wrong for
- i386_parse_name() to call parse_register(). This being a hook from the
- expression parser, it shouldn't be resolving e.g. equated symbols.
- That's relevant only for all other callers of parse_register().
-
- To compensate, in Intel syntax mode check_register() needs calling;
- perhaps not doing so was an oversight right when the function was
- introduced. This is necessary in particular to force EVEX encoding when
- VRex registers are used (but of course also to reject bad uses of
- registers, i.e. fully matching what parse_register() needs it for).

- (indicating that part of the comment was wrong). Finally for there to be
- a usable name in slot 1, files_in_use needs to be larger than 1 and slot
- 1's (rather than slot 0's) name needs to be non-NULL.

- gas/Dwarf5: drop dead code
- Commit 3417bfca676f ("GAS: DWARF-5: Ensure that the 0'th entry in the
- directory table contains the current... ") added a "dwarf_level < 5"
- check to out_dir_and_file_list(). This rendered dead that branch of the
- construct, due to the enclosing if()'s "DWARF2_LINE_VERSION >= 5".
- Delete that code as well as the corresponding part of the comment.
-
- While there also drop a redundant "dirs != NULL": "dirs" will always be
- non-NULL when dirs_in_use is not zero.

- gas/Dwarf: improve debug info generation from .irp and alike blocks
- Tying the bumping of the logical line number to reading from the
- original source file looks wrong: Upon finishing of the processing of an
- sb the original values will be restored anyway. Yet without bumping the
- line counter uses of .line inside e.g. an .irp construct won't have the
- intended effect: Such uses may be necessary to ensure proper debug info
- is emitted in particular when switching sections inside the .irp body,
- as dwarf2_gen_line_info() would bail without doing anything when it
- finds the line number unchanged from what it saw last.

- ELF32: don't silently truncate relocation addends
- At least x86-64's x32 sub-mode and RISC-V's 32-bit mode calculate
- addends as 64-bit values, but store them in signed 32-bit fields when
- generating the file without encountering any earlier error. When the
- relocated field is a 64-bit one, the value resulting after processing
- the relocation record when linking (or the latest when loading) may
- thus be wrong due to the truncation.
-
- With the code change in place, one x32 testcase actually triggers the
- new diagnostic. That one case of too large a (negative) addend is being
- adjusted alongside the addition of a new testcase to actually trigger
- the new error. (Note that due to internal BFD behavior the relocation in
- .data doesn't get processed anymore after the errors in .text.)
-
- Note that in principle it is possible to express 64-bit relocations in
- ELF32, but this would require .rel relocations, i.e. with the addend
- stored in the 64-bit field being relocated. But I guess it would be a
- lot of effort for little gain to actually support this.

- gas: retain whitespace between strings
- Macro arguments may be separated by commas or just whitespace. Macro
- arguments may also be quoted (where one level of quotes is removed in
- the course of determining the values for the respective formal
- parameters). Furthermore this quote removal knows _two_ somewhat odd
- escaping mechanisms: One, apparently in existence forever, is that a
- pair of quotes counts as the escaping of a quote, with the pair being
- transformed to a single quote in the course of quote removal. The other
- (introduced by c06ae4f232e6) looks more usual on the surface in that it
- deals with \" sequences, but it _retains_ the escaping \. Hence only the
- former mechanism is suitable when the value to be used by the macro body
- is to contain a quote. Yet this results in ambiguity of what "a""b" is
- intended to mean; elsewhere (e.g. for .ascii) it represents two
- successive string literals. However, in any event is the above different
- from "a" "b": I don't think this can be viewed the same as "a""b" when
- processing macro arguments.
-
- Change the scrubber to retain such whitespace, by making the processing
- of strings more similar to that of symbols. And indeed this appears to
- make sense when taking into account that for quite a while gas has been
- supporting quoted symbol names.
-
- Taking a more general view, however, the change doesn't go quite far
- enough. There are further cases where significant whitespace is removed
- by the scrubber. The new testcase enumerates a few in its ".if 0"
- section. I'm afraid the only way that I see to deal with this would be
- to significantly simplify the scrubber, such that it wouldn't do much
- more than collapse sequences of unquoted whitespace into a single blank.
- To be honest problems in this area aren't really surprising when seeing
- that there's hardly any checking of .macro use throughout the testsuite
- (and in particular in the [relatively] generic tests under all/).

- aarch64: Add an aarch64_nat_target mixin class.
- This class includes platform-independent target methods for hardware
- breakpoints and watchpoints using routines from
- nat/aarch64-hw-point.c.
-
- stopped_data_address is not platform-independent since the FAR
- register holding the address for a breakpoint hit must be fetched in a
- platform-specific manner. However, aarch64_stopped_data_address is
- provided as a helper routine which performs platform-independent
- validation given the value of the FAR register.
-
- For tracking the per-process debug register mirror state, use an
- unordered_map indexed by pid as recently adopted in x86-nat.c rather
- than a manual linked-list.

-
- nat: Split out platform-independent aarch64 debug register support.
- Move non-Linux-specific support for hardware break/watchpoints from
- nat/aarch64-linux-hw-point.c to nat/aarch64-hw-point.c. Changes
- beyond a simple split of the code are:
-
- - aarch64_linux_region_ok_for_watchpoint and
- aarch64_linux_any_set_debug_regs_state renamed to drop linux_ as
- they are not platform specific.
-
- - Platforms must implement the aarch64_notify_debug_reg_change
- function which is invoked from the platform-independent code when a
- debug register changes for a given debug register state. This does
- not use the indirection of a 'low' structure as is done for x86.
-
- - The handling for kernel_supports_any_contiguous_range is not
- pristine. For non-Linux it is simply defined to true. Some uses of
- this could perhaps be implemented as new 'low' routines for the
- various places that check it instead?
-
- - Pass down ptid into aarch64_handle_breakpoint and
- aarch64_handle_watchpoint rather than using current_lwp_ptid which
- is only defined on Linux. In addition, pass the ptid on to
- aarch64_notify_debug_reg_change instead of the unused state
- argument.

-
- gdb/python: add gdb.format_address function
- Add a new function, gdb.format_address, which is a wrapper around
- GDB's print_address function.
-
- This method takes an address, and returns a string with the format:
-
- ADDRESS <SYMBOL+OFFSET>
-
- Where, ADDRESS is the original address, formatted as hexadecimal,
- SYMBOL is a symbol with an address lower than ADDRESS, and OFFSET is
- the offset from SYMBOL to ADDRESS in decimal.
-
- If there's no SYMBOL suitably close to ADDRESS then the
- <SYMBOL+OFFSET> part is not included.
-
- This is useful if a user wants to write a Python script that
- pretty-prints addresses, the user no longer needs to do manual symbol
- lookup, or worry about correctly formatting addresses.
-
- Additionally, there are some settings that effect how GDB picks
- SYMBOL, and whether the file name and line number should be included
- with the SYMBOL name, the gdb.format_address function ensures that the
- users Python script also benefits from these settings.
-
- The gdb.format_address by default selects SYMBOL from the current
- inferiors program space, and address is formatted using the
- architecture for the current inferior. However, a user can also
- explicitly pass a program space and architecture like this:
-
- gdb.format_address(ADDRESS, PROGRAM_SPACE, ARCHITECTURE)
-
- In order to format an address for a different inferior.
-
- Notes on the implementation:
-
- In py-arch.c I extended arch_object_to_gdbarch to add an assertion for
- the type of the PyObject being worked on. Prior to this commit all
- uses of arch_object_to_gdbarch were guaranteed to pass this function a
- gdb.Architecture object, but, with this commit, this might not be the
- case.
-
- So, with this commit I've made it a requirement that the PyObject be a
- gdb.Architecture, and this is checked with the assert. And in order
- that callers from other files can check if they have a
- gdb.Architecture object, I've added the new function
- gdbpy_is_architecture.
-
- In py-progspace.c I've added two new function, the first
- progspace_object_to_program_space, converts a PyObject of type
- gdb.Progspace to the associated program_space pointer, and
- gdbpy_is_progspace checks if a PyObject is a gdb.Progspace or not.

- Watchpoint followed by catchpoint misreports watchpoint (PR gdb/28621)
- If GDB reports a watchpoint hit, and then the next event is not
- TARGET_WAITKIND_STOPPED, but instead some event for which there's a
- catchpoint, such that GDB calls bpstat_stop_status, GDB mistakenly
- thinks the watchpoint triggered. Vis, using foll-fork.c:
-
- (gdb) awatch v
- Hardware access (read/write) watchpoint 2: v
- (gdb) catch fork
- Catchpoint 3 (fork)
- (gdb) c
- Continuing.
-
- Hardware access (read/write) watchpoint 2: v
-
- Old value = 0
- New value = 5
- main () at gdb.base/foll-fork.c:16
- 16 pid = fork ();
- (gdb)
- Continuing.
-
- Hardware access (read/write) watchpoint 2: v <<<<
- <<<< these lines are spurious
- Value = 5 <<<<
-
- Catchpoint 3 (forked process 1712369), arch_fork (ctid=0x7ffff7fa4810) at arch-fork.h:49
- 49 arch-fork.h: No such file or directory.
- (gdb)
-
- The problem is that when we handle the fork event, nothing called
- watchpoints_triggered before calling bpstat_stop_status. Thus, each
- watchpoint's watchpoint_triggered field was still set to
- watch_triggered_yes from the previous (real) watchpoint stop.
- watchpoint_triggered is only current called in the handle_signal_stop
- path, when handling TARGET_WAITKIND_STOPPED.
-
- This fixes it by adding watchpoint_triggered calls in the other events
- paths that call bpstat_stop_status. But instead of adding them
- explicitly, it adds a new function bpstat_stop_status_nowatch that
- wraps bpstat_stop_status and calls watchpoint_triggered, and then
- replaces most calls to bpstat_stop_status with calls to
- bpstat_stop_status_nowatch.
-
- This required constifying watchpoints_triggered.
-
- New test included, which fails without the fix.

- gdb/x86: handle stap probe arguments in xmm registers
- On x86 machines with xmm register, and with recent versions of
- systemtap (and gcc?), it can occur that stap probe arguments will be
- placed into xmm registers.
-
- I notice this happening on a current Fedora Rawhide install with the
- following package versions installed:
-
- $ rpm -q glibc systemtap gcc
- glibc-2.35.9000-10.fc37.x86_64
- systemtap-4.7~pre16468670g9f253544-1.fc37.x86_64
- gcc-12.0.1-0.12.fc37.x86_64
-
- If I check the probe data in libc, I see this:
-
- $ readelf -n /lib64/libc.so.6
- ...
- stapsdt 0x0000004d NT_STAPSDT (SystemTap probe descriptors)
- Provider: libc
- Name: pthread_start
- Location: 0x0000000000090ac3, Base: 0x00000000001c65c4, Semaphore: 0x0000000000000000
- Arguments: 8@%xmm1 8@1600(%rbx) 8@1608(%rbx)
- stapsdt 0x00000050 NT_STAPSDT (SystemTap probe descriptors)
- Provider: libc
- Name: pthread_create
- Location: 0x00000000000912f1, Base: 0x00000000001c65c4, Semaphore: 0x0000000000000000
- Arguments: 8@%xmm1 8@%r13 8@8(%rsp) 8@16(%rsp)
- ...
-
- Notice that for both of these probes, the first argument is a uint64_t
- stored in the xmm1 register.
-
- Unfortunately, if I try to use this probe within GDB, then I can't
- view the first argument. Here's an example session:
-
- $ gdb $(which gdb)
- (gdb) start
- ...
- (gdb) info probes stap libc pthread_create
- ...
- (gdb) break *0x00007ffff729e2f1 # Use address of probe.
- (gdb) continue
- ...
- (gdb) p $_probe_arg0
- Invalid cast.
-
- What's going wrong? If I re-run my session, but this time use 'set
- debug stap-expression 1', this is what I see:
-
- (gdb) set debug stap-expression 1
- (gdb) p $_probe_arg0
- Operation: UNOP_CAST

-
- The important bit is this:
-
- Operation: UNOP_CAST
- Operation: OP_REGISTER
- String: xmm1
- Type: uint64_t
-
- Which is where we cast the xmm1 register to uint64_t. And the final
- piece of the puzzle is:
-
- (gdb) ptype $xmm1
- type = union vec128 {
- v8bf16 v8_bfloat16;
- v4f v4_float;
- v2d v2_double;

- v4i32 v4_int32;
- v2i64 v2_int64;
- uint128_t uint128;
- }
-
- So, we are attempting to cast a union type to a scalar type, which is
- not supporting in C/C++, and as a consequence GDB's expression
- evaluator throws an error when we attempt to do this.
-
- The first approach I considered for solving this problem was to try
- and make use of gdbarch_stap_adjust_register. We already have a
- gdbarch method (gdbarch_stap_adjust_register) that allows us to tweak
- the name of the register that we access. Currently only x86
- architectures use this to transform things like ax to eax in some
- cases.
-
- I wondered, what if we change gdbarch_stap_adjust_register to do more
- than just change the register names? What if this method instead
- became gdbarch_stap_read_register. This new method would return a
- operation_up, and would take the register name, and the type we are
- trying to read from the register, and return the operation that
- actually reads the register.
-
- The default implementation of this method would just use
- user_reg_map_name_to_regnum, and then create a register_operation,
- like we already do in stap_parse_register_operand. But, for x86
- architectures this method would fist possibly adjust the register
- name, then do the default action to read the register. Finally, for
- x86 this method would spot when we were accessing an xmm register,
- and, based on the type being pulled from the register, would extract
- the correct field from the union.
-
- The benefit of this approach is that it would work with the expression
- types that GDB currently supports. The draw back would be that this
- approach would not be very generic. We'd need code to handle each
- sub-field size with an xmm register. If other architectures started
- using vector registers for probe arguments, those architectures would
- have to create their own gdbarch_stap_read_register method. And
- finally, the type of the xmm registers comes from the type defined in
- the target description, there's a risk that GDB might end up
- hard-coding the names of type sub-fields, then if a target uses a
- different target description, with different field names for xmm
- registers, the stap probes would stop working.
-
- And so, based on all the above draw backs, I rejected this first
- approach.
-
- My second plan involves adding a new expression type to GDB called
- unop_extract_operation. This new expression takes a value and a type,
- during evaluation the value contents are fetched, and then a new value
- is extracted from the value contents (based on type). This is similar
- to the following C expression:
-
- result_value = *((output_type *) &input_value);
-
- Obviously we can't actually build this expression in this case, as the
- input_value is in a register, but hopefully the above makes it clearer
- what I'm trying to do.
-
- The benefit of the new expression approach is that this code can be
- shared across all architectures, and it doesn't care about sub-field
- names within the union type.
-
- The draw-backs that I see are potential future problems if arguments
- are not stored within the least significant bytes of the register.
- However if/when that becomes an issue we can adapt the
- gdbarch_stap_read_register approach to allow architectures to control
- how a value is extracted.
-
- For testing, I've extended the existing gdb.base/stap-probe.exp test
- to include a function that tries to force an argument into an xmm
- register. Obviously, that will only work on a x86 target, so I've
- guarded the new function with an appropriate GCC define. In the exp
- script we use readelf to check if the probe exists, and is using the
- xmm register.
-
- If the probe doesn't exist then the associated tests are skipped.
-
- If the probe exists, put isn't using the xmm register (which will
- depend on systemtap/gcc versions), then again, the tests are skipped.
-
- Otherwise, we can run the test. I think the cost of running readelf
- is pretty low, so I don't feel too bad making all the non-xmm targets
- running this step.
-
- I found that on a Fedora 35 install, with these packages installed, I
- was able to run this test and have the probe argument be placed in an
- xmm register:
-
- $ rpm -q systemtap gcc glibc
- systemtap-4.6-4.fc35.x86_64
- gcc-11.2.1-9.fc35.x86_64
- glibc-2.34-7.fc35.x86_64
-
- Finally, as this patch adds a new operation type, then I need to
- consider how to generate an agent expression for the new operation
- type.
-
- I have kicked the can down the road a bit on this. In the function
- stap_parse_register_operand, I only create a unop_extract_operation in
- the case where the register type is non-scalar, this means that in
- most cases I don't need to worry about generating an agent expression
- at all.
-
- In the xmm register case, when an unop_extract_operation will be
- created, I have sketched out how the agent expression could be
- handled, however, this code is currently not reached. When we try to
- generate the agent expression to place the xmm register on the stack,
- GDB hits this error:
-
- (gdb) trace -probe-stap test:xmmreg
- Tracepoint 1 at 0x401166
- (gdb) actions
- Enter actions for tracepoint 1, one per line.
- End with a line saying just "end".
- >collect $_probe_arg0
- Value not scalar: cannot be an rvalue.
-
- This is because GDB doesn't currently support placing non-scalar types
- on the agent expression evaluation stack. Solving this is clearly
- related to the original problem, but feels a bit like a second
- problem. I'd like to get feedback on whether my approach to solving
- the original problem is acceptable or not before I start looking at
- how to handle xmm registers within agent expressions.

- x86: don't suppress overflow diagnostics in x32 mode

- detection shouldn't be suppressed just because rela relocations are
- going to be used.
-
- The extra check against NO_RELOC is actually a result of an ilp32 test

- [gdb/testsuite] test a function call by hand from pretty printer
- The test case added here is testing the bug gdb/28856, where calling a
- function by hand from a pretty printer makes GDB crash. There are 6
- mechanisms to trigger this crash in the current test, using the commands
- backtrace, up, down, finish, step and continue. Since the failure happens
- because of use-after-free (more details below) the tests will always
- have a chance of passing through sheer luck, but anecdotally they seem
- to fail all of the time.
-
- The reason GDB is crashing is a use-after-free problem. The above
- mentioned functions save a pointer to the current frame's information,
- then calls the pretty printer, and uses the saved pointer for different
- reasons, depending on the function. The issue happens because
- call_function_by_hand needs to reset the obstack to get the current
- frame, invalidating the saved pointer.

- gdb/testsuite: Installed-GDB testing & data-directory
- In testsuite/README, we suggest that you can run the testsuite against
- some other GDB binary by using:
-
- make check RUNTESTFLAGS=GDB=/usr/bin/gdb
-
- However, that example isn't fully correct, because with that command
- line, the testsuite will still pass
-
- -data-directory=[pwd]/../data-directory
-
- to /usr/bin/gdb, like e.g.:
-
- ...
- builtin_spawn /usr/bin/gdb -nw -nx -data-directory /home/pedro/gdb/build/gdb/testsuite/../data-directory -iex set height 0 -iex set width 0
- ...
-
- while if you're testing an installed GDB (the system GDB being the
- most usual scenario), then you should normally let it use its own
- configured directory, not the just-built GDB's data directory.
-
- This commit improves the status quo with the following two changes:
-
- - if the user specifies GDB on the command line, then by default,
- don't start GDB with the -data-directory command line option.
- I.e., let the tested GDB use its own configured data directory.
-
- - let the user override the data directory, via a new
- GDB_DATA_DIRECTORY global. This replaces the existing
- BUILD_DATA_DIRECTORY variable in testsuite/lib/gdb.exp, which
- wasn't overridable, and was a bit misnamed for the new purpose.
-
- So after this, the following commands I believe behave intuitively:
-
- # Test the non-installed GDB in some build dir:
-
- make check \
- RUNTESTFLAGS="GDB=/path/to/other/build/gdb \
- GDB_DATA_DIRECTORY=/path/to/other/build/gdb/data-directory"
-
- # Test the GDB installed in some prefix:
-
- make check \
- RUNTESTFLAGS="GDB=/opt/gdb/bin/gdb"
-
- # Test the built GDB with some alternative data directory, e.g., the
- system GDB's data directory:
-
- make check \
- RUNTESTFLAGS="GDB_DATA_DIRECTORY=/usr/share/gdb"

- gdb/python: remove gdb._mi_commands dict
- The motivation for this patch is the fact that py-micmd.c doesn't build
- with Python 2, due to PyDict_GetItemWithError being a Python 3-only
- function:
-
- CXX python/py-micmd.o
- /home/smarchi/src/binutils-gdb/gdb/python/py-micmd.c: In function ‘int micmdpy_uninstall_command(micmdpy_object*)’:
- /home/smarchi/src/binutils-gdb/gdb/python/py-micmd.c:430:20: error: ‘PyDict_GetItemWithError’ was not declared in this scope; did you mean ‘PyDict_GetItemString’?
- 430 | PyObject *curr = PyDict_GetItemWithError (mi_cmd_dict.get (),
- | ^~~~~~~~~~~~~~~~~~~~~~~
- | PyDict_GetItemString
-
- A first solution to fix this would be to try to replace
- PyDict_GetItemWithError equivalent Python 2 code. But I looked at why
- we are doing this in the first place: it is to maintain the
- `gdb._mi_commands` Python dictionary that we use as a `name ->
- gdb.MICommand object` map. Since the `gdb._mi_commands` dictionary is
- never actually used in Python, it seems like a lot of trouble to use a
- Python object for this.
-
- My first idea was to replace it with a C++ map
- (std::unordered_map<std::string, gdbpy_ref<micmdpy_object>>). While
- implementing this, I realized we don't really need this map at all. The
- mi_command_py objects registered in the main MI command table can own
- their backing micmdpy_object (that's a gdb.MICommand, but seen from the
- C++ code). To know whether an mi_command is an mi_command_py, we can
- use a dynamic cast. Since there's one less data structure to maintain,
- there are less chances of messing things up.
-
- - Change mi_command_py::m_pyobj to a gdbpy_ref, the mi_command_py is
- now what keeps the MICommand alive.
- - Set micmdpy_object::mi_command in the constructor of mi_command_py.
- If mi_command_py manages setting/clearing that field in
- swap_python_object, I think it makes sense that it also takes care of
- setting it initially.
- - Move a bunch of checks from micmdpy_install_command to
- swap_python_object, and make them gdb_asserts.
- - In micmdpy_install_command, start by doing an mi_cmd_lookup. This is
- needed to know whether there's a Python MI command already registered
- with that name. But we can already tell if there's a non-Python
- command registered with that name. Return an error if that happens,
- rather than waiting for insert_mi_cmd_entry to fail. Change the
- error message to "name is already in use" rather than "may already be
- in use", since it's more precise.
-
- I asked Andrew about the original intent of using a Python dictionary
- object to hold the command objects. The reason was to make sure the
- objects get destroyed when the Python runtime gets finalized, not later.
- Holding the objects in global C++ data structures and not doing anything
- more means that the held Python objects will be decref'd after the
- Python interpreter has been finalized. That's not desirable. I tried
- it and it indeed segfaults.
-
- Handle this by adding a gdbpy_finalize_micommands function called in
- finalize_python. This is the mirror of gdbpy_initialize_micommands
- called in do_start_initialization. In there, delete all Python MI
- commands. I think it makes sense to do it this way: if it was somehow
- possible to unload Python support from GDB in the middle of a session
- we'd want to unregister any Python MI command. Otherwise, these MI
- commands would be backed with a stale PyObject or simply nothing.
-
- Delete tests that were related to `gdb._mi_commands`.

- Implement gdbarch_stack_frame_destroyed_p for aarch64
- The internal AdaCore testsuite has a test that checks that an
- out-of-scope watchpoint is deleted. This fails on some aarch64
- configurations, reporting an extra stop:
-
- (gdb) continue
- Continuing.
-
- Thread 3 hit Watchpoint 2: result

- 13 end Get_Val;
-
- I believe what is happening here is that the variable is stored at:
-
- <efa> DW_AT_location : 2 byte block: 91 7c (DW_OP_fbreg: -4)
-
- and the extra stop is reported just before a return, when the ldp
- instruction is executed:
-
- 0x0000000040021644 <+204>: ldp x29, x30, [sp], #48
- 0x0000000040021648 <+208>: ret
-
- This instruction modifies the frame base calculation, and so the test
- picks up whatever memory is pointed to in the callee frame.
-
- Implementing the gdbarch hook gdbarch_stack_frame_destroyed_p fixes
- this problem.
-
- As usual with this sort of patch, it has passed internal testing, but
- I don't have a good way to try it with dejagnu. So, I don't know
- whether some existing test covers this. I suspect there must be one,
- but it's also worth noting that this test passes for aarch64 in some
- configurations -- I don't know what causes one to fail and another to
- succeed.

- x86: don't accept base architectures as extensions

- followed by any number of extensions. Accepting a base architecture in

-
- While there also avoid setting CpuNo64: Like Cpu64 this is driven

-
- x86: drop L1OM/K1OM support from gas
- This was only rudimentary support anyway; none of the sub-architecture

-
- x86: assorted IAMCU CPU checking fixes
- The checks done by check_cpu_arch_compatible() were halfway sensible
- only at the time where only L1OM support was there. The purpose,
- however, has always been to prevent bad uses of .arch (turning off the
- base CPU "feature" flag) while at the same time permitting extensions to
- be enabled / disabled. In order to achieve this (and to prevent
- regressions when L1OM and K1OM support are removed)
- - set CpuIAMCU in CPU_IAMCU_FLAGS,
- - adjust the IAMCU check in the function itself (the other two similarly
- broken checks aren't adjusted as they're slated to be removed anyway),
- - avoid calling the function for extentions (which would never have the
- base "feature" flag set),
- - add a new testcase actually exercising ".arch iamcu" (which would also
- regress with the planned removal).

- gdb: work around prompt corruption caused by bracketed-paste-mode
- In this commit:
-
- commit b4f26d541aa7224b70d363932e816e6e1a857633
- Date: Tue Mar 2 13:42:37 2021 -0700

- Import GNU Readline 8.1
-
- We imported readline 8.1 into GDB. As a consequence bug PR cli/28833
- was reported. This bug spotted that, when the user terminated GDB by
- sending EOF (usually bound to Ctrl+d), the last prompt would become
- corrupted. Here's what happens, the user is sat at a prompt like
- this:
-
- (gdb)
-
- And then the user sends EOF (Ctrl+d), we now see this:
-
- quit)
- ... gdb terminates, and we return to the shell ...
-
- Notice the 'quit' was printed over the prompt.
-
- This problem is a result of readline 8.1 enabling bracketed paste mode
- by default. This problem is present in readline 8.0 too, but in that
- version of readline bracketed paste mode is off by default, so a user
- will not see the bug unless they specifically enable the feature.
-
- Bracketed paste mode is available in readline 7.0 too, but the bug
- is not present in this version of readline, see below for why.
-
- What causes this problem is how readline disables bracketed paste
- mode. Bracketed paste mode is a terminal feature that is enabled and
- disabled by readline emitting a specific escape sequence. The problem
- for GDB is that the escape sequence to disable bracketed paste mode
- includes a '\r' character at the end, see this thread for more
- details:
-
- https://lists.gnu.org/archive/html/bug-bash/2018-01/msg00097.html
-
- The change to add the '\r' character to the escape sequence used to
- disable bracketed paste mode was introduced between readline 7.0 and
- readline 8.0, this is why the bug would not occur when using older
- versions of readline (note: I don't know if its even possible to build
- GDB using readline 7.0. That really isn't important, I'm just
- documenting the history of this issue).
-
- So, the escape sequence to disable bracketed paste mode is emitted
- from the readline function rl_deprep_terminal, this is called after
- the user has entered a complete command and pressed return, or, if the
- user sends EOF.
-
- However, these two cases are slightly different. In the first case,
- when the user has entered a command and pressed return, the cursor
- will have moved to the next, empty, line, before readline emits the
- escape sequence to leave bracketed paste mode. The final '\r'
- character moves the cursor back to the beginning of this empty line,
- which is harmless.
-
- For the EOF case though, this is not what happens. Instead, the
- escape sequence to leave bracketed paste mode is emitted on the same
- line as the prompt. The final '\r' moves the cursor back to the start
- of the prompt line. This leaves us ready to override the prompt.
-
- It is worth noting, that this is not the intended behaviour of
- readline, in rl_deprep_terminal, readline should emit a '\n' character
- when EOF is seen. However, due to a bug in readline this does not
- happen (the _rl_eof_found flag is never set). This is the first
- readline bug that effects GDB.
-
- GDB prints the 'quit' message from command_line_handler (in
- event-top.c), this function is called (indirectly) from readline to
- process the complete command line, but also in the EOF case (in which
- case the command line is set to nullptr). As this is part of the
- callback to process a complete command, this is called after readline
- has disabled bracketed paste mode (by calling rl_deprep_terminal).
-
- And so, when bracketed paste mode is in use, rl_deprep_terminal leaves
- the cursor at the start of the prompt line (in the EOF case), and
- command_line_handler then prints 'quit', which overwrites the prompt.
-
- The solution to this problem is to print the 'quit' message earlier,
- before rl_deprep_terminal is called. This is easy to do by using the
- rl_deprep_term_function hook. It is this hook that usually calls
- rl_deprep_terminal, however, if we replace this with a new function,
- we can print the 'quit' string, and then call rl_deprep_terminal
- ourselves. This allows the 'quit' to be printed before
- rl_deprep_terminal is called.
-
- The problem here is that there is no way in rl_deprep_terminal to know
- if readline is processing EOF or not, and as a result, we don't know
- when we should print 'quit'. This is the second readline bug that
- effects GDB.
-
- Both of these readline issues are discussed in this thread:
-
- https://lists.gnu.org/archive/html/bug-readline/2022-02/msg00021.html
-
- The result of that thread was that readline was patched to address
- both of these issues.
-
- Now it should be easy to backport the readline fix to GDB's in tree
- copy of readline, and then change GDB to make use of these fixes to
- correctly print the 'quit' string.
-
- However, we are just about to branch GDB 12, and there is concern from
- some that changing readline this close to a new release is a risky
- idea, see this thread:
-
- https://sourceware.org/pipermail/gdb-patches/2022-March/186391.html
-
- So, this commit doesn't change readline at all. Instead, this commit
- is the smallest possible GDB change in order to avoid the prompt
- corruption.
-
- In this commit I change GDB to print the 'quit' string on the line
- after the prompt, but only when bracketed paste mode is on. This
- avoids the overwriting issue, the user sees this:
-
- (gdb)
- quit
- ... gdb terminates, and returns to the shell ...
-
- This isn't ideal, but is better than the existing behaviour. After
- GDB 12 has branched, we can backport the readline fix, and apply a
- real fix to GDB.

- Reimplement array concatenation for Ada and D
- This started as a patch to implement string concatenation for Ada.
- However, while working on this, I looked at how this code could
- possibly be called. It turns out there are only two users of
- concat_operation: Ada and D. So, in addition to implementing this for
- Ada, this patch rewrites value_concat, removing the odd "concatenate
- or repeat" semantics, which were completely unused. As Ada and D both
- seem to represent strings using TYPE_CODE_ARRAY, this removes the
- TYPE_CODE_STRING code from there as well.
-
- Remove eval_op_concat
- eval_op_concat has code to search for an operator overload of
- BINOP_CONCAT. However, the operator overloading code is specific to
- C++, which does not have this operator. And,
- binop_types_user_defined_p rejects this case right at the start, and
- value_x_binop does not handle this case. I think this code has been
- dead for a very long time. This patch removes it and hoists the
- remaining call into concatenation::evaluate, removing eval_op_concat
- entirely.

- Powerpc fix for gdb.base/ending-run.exp
- The last two tests in gdb.base/ending-run.exp case fail on Powerpc when the
- system does not have the needed glibc debug-info files loaded. In this
- case, gdb is not able to determine where execution stopped. This behavior
- looks as follows for the test case:
-
- The next to the last test does a next command when the program is stopped
- at the closing bracket for main. The message printed is:
-
- 0x00007ffff7d01524 in ?? () from /lib/powerpc64le-linux-gnu/libc.so.6
-
- which fails to match any of the test_multiple options.
-
- The test then does another next command. On Powerpc, the
- message printed it:
-
- Cannot find bounds of current function
-
- The test fails as the output does not match any of the options for the
- gdb_test_multiple.
-
- I checked the behavior on Powerpc to see if this is typical.
- I ran gdb on the following simple program as shown below.
-
- #include <stdio.h>
- int
- main(void)
- {
- printf("Hello, world!\n");
- return 0;
- }
-
- gdb ./hello_world
- <snip the gdb start info>
-
- Type "apropos word" to search for commands related to "word"...
- Reading symbols from ./hello_world...
- (No debugging symbols found in ./hello_world)
- (gdb) break main
- Breakpoint 1 at 0x818
- (gdb) r
-
- Starting program: /home/carll/hello_world
- [Thread debugging using libthread_db enabled]
- Using host libthread_db library "/lib/powerpc64le-linux-gnu/libthread_db.so.1".
-
- Breakpoint 1, 0x0000000100000818 in main ()
- (gdb) n
- Single stepping until exit from function main,
- which has no line number information.
- Hello, world!
- 0x00007ffff7d01524 in ?? () from /lib/powerpc64le-linux-gnu/libc.so.6
- (gdb) n
- Cannot find bounds of current function
-
- So it would seem that the messages seen from the test case are
- "normal" output for Powerpc when the debug-info is not available.
-
- The following patch adds the output from Powerpc as an option
- to the gdb_test_multiple statement, identifying the output as the expected
- output on Powerpc without the needed debug-info files installed.
-
- The patch has been tested on a Power 10 system and an Intel
- 64-bit system. No additional regression failures were seen on
- either platform.

- GDB notifies users about user selected thread changes somewhat

-
- Consider GDB debugging a multi-threaded inferior with both CLI and GDB/MI
- interfaces connected to separate terminals.
-
- Assuming inferior is stopped and thread 1 is selected, when a thread

-
- -thread-select 2
- ^done,new-thread-id="2",frame={level="0",addr="0x00005555555551cd",func="child_sub_function",args=[],file="/home/jv/Projects/gdb/users_jv_patches/gdb/testsuite/gdb.mi/user-selected-context-sync.c",fullname="/home/uuu/gdb/gdb/testsuite/gdb.mi/user-selected-context-sync.c",line="30",arch="i386:x86-64"}
- (gdb)
-
- and on CLI terminal we get the notification (as expected):
-
- [Switching to thread 2 (Thread 0x7ffff7daa640 (LWP 389659))]
- #0 child_sub_function () at /home/uuu/gdb/gdb/testsuite/gdb.mi/user-selected-context-sync.c:30
- 30 volatile int dummy = 0;
-
- However, now that thread 2 is selected, if thread 1 is selected
- using 'thread-select --thread 1 1' command on GDB/MI terminal
- terminal:
-
- -thread-select --thread 1 1
- ^done,new-thread-id="1",frame={level="0",addr="0x0000555555555294",func="main",args=[],file="/home/jv/Projects/gdb/users_jv_patches/gdb/testsuite/gdb.mi/user-selected-context-sync.c",fullname="/home/jv/Projects/gdb/users_jv_patches/gdb/testsuite/gdb.mi/user-selected-context-sync.c",line="66",arch="i386:x86-64"}
- (gdb)
-
- but no notification is printed on CLI terminal, despite the fact
- that user selected thread has changed.
-
- The problem is that when `-thread-select --thread 1 1` is executed
- then thread is switched to thread 1 before mi_cmd_thread_select () is
- called, therefore the condition "inferior_ptid != previous_ptid"
- there does not hold.
-
- To address this problem, we have to move notification logic up to
- mi_cmd_execute () where --thread option is processed and notify
- user selected contents observers there if context changes.
-
- However, this in itself breaks GDB/MI because it would cause context
- notification to be sent on MI channel. This is because by the time
- we notify, MI notification suppression is already restored (done in
- mi_command::invoke(). Therefore we had to lift notification suppression
- logic also up to mi_cmd_execute (). This change in made distinction
- between mi_command::invoke() and mi_command::do_invoke() unnecessary
- as all mi_command::invoke() did (after the change) was to call
- do_invoke(). So this patches removes do_invoke() and moves the command
- execution logic directly to invoke().
-
- With this change, all gdb.mi tests pass, tested on x86_64-linux.

- binutils/readelf: build against msgpack, dump NT_AMDGPU_METADATA note contents
- The AMDGPU HSA OS ABI (code object v3 and above) defines the
- NT_AMDGPU_METADATA ELF note [1]. The content is a msgpack object
- describing, among other things, the kernels present in the code object
- and how to call them.
-
- I think it would be useful for readelf to be able to display the content
- of those notes. msgpack is a structured format, a bit like JSON, except
- not text-based. It is therefore possible to dump the contents in
- human-readable form without knowledge of the specific layout of the
- note.
-
- Add configury to binutils to optionally check for the msgpack C library
- [2]. Add There is a new --with{,out}-msgpack configure flag, and the actual
- library lookup is done using pkg-config.
-
- If msgpack support is enabled, dumping a NT_AMDGPU_METADATA note looks
- like:
-
- $ readelf --notes amdgpu-code-object
- Displaying notes found in: .note
- Owner Data size Description
- AMDGPU 0x0000040d NT_AMDGPU_METADATA (code object metadata)
- {
- "amdhsa.kernels": [
- {
- ".args": [
- {
- ".address_space": "global",
- ".name": "out.coerce",
- ".offset": 0,
- ".size": 8,
- ".value_kind": "global_buffer",
- },
- <snip>
-
- If msgpack support is disabled, dump the contents as hex, as is done
- with notes that are not handled in a special way. This allows one to
- decode the contents manually (maybe using a command-line msgpack
- decoder) if really needed.

- Decode and print the AMDGPU-specific fields of e_flags, as documented

- https://llvm.org/docs/AMDGPUUsage.html#header
-
- That is:

- The result looks like:

-
- The flags for the "HSA" OS ABI are properly versioned and documented on
- that page. But the NONE, PAL and MESA3D OS ABIs are not well documented
- nor versioned. Taking a peek at the LLVM source code, we see that they
- encode their flags the same way as HSA v3. For example, for PAL:

- $ ./configure --target=amdgcn-hsa-amdhsa --disable-gas

-
- The specific AMDGCN models added here are a bit arbitrary, based on

- updated in the future anyway. The complete up-to-date list of existing
- AMDGPU models can be found here:
-
- https://llvm.org/docs/AMDGPUUsage.html#processors

- Make gdb.fortran/{array-slices,lbound-ubound} work against gdbserver
- gdb.fortran/array-slices.exp and gdb.fortran/lbound-ubound.exp were
- recently disabled unless testing with the native target, because they
- rely on inferior I/O. However, when testing against gdbserver using
- the native-gdbserver/native-extended-gdbserver boards, we do have
- access to inferior I/O.
-
- The right way to check whether the board can do I/O, is via checking
- the gdb,noinferiorio board variable. Switch to using that.
-
- And then, tweak the testcases to expect output to appear in
- inferior_spawn_id, instead of gdb_spawn_id. When testing against the
- native target, inferior_spawn_id is the same as gdb_spawn_id. When
- testing against gdbserver, it maps to gdbserver_spawn_id.
-
- This exposed a buglet in gdb.fortran/array-slices.f90's show_1d
- subroutine -- it was missing printing newline at the end of the
- "Expected GDB Output" text, leading to a test timeout. All other
- subroutines end with advance=yes, except this one. Fix it by using
- advance=yes here too.

- PowerPC64 extended instructions in powerpc_macros
- The extended instructions implemented in powerpc_macros aren't used by
- the disassembler. That means instructions like "sldi r3,r3,2" appear
- in disassembly as "rldicr r3,r3,2,61", which is annoying since many
- other extended instructions are shown.
-
- Note that some of the instructions moved out of the macro table to the
- opcode table won't appear in disassembly, because they are aliases
- rather than a subset of the underlying raw instruction. If enabled,
- rotrdi, extrdi, extldi, clrlsldi, and insrdi would replace all
- occurrences of rotldi, rldicl, rldicr, rldic and rldimi. (Or many
- occurrences in the case of clrlsldi if n <= b was added to the extract

- gdb/testsuite: rename a proc and fix a typo
- Rename a proc in gdb.mi/user-selected-context-sync.exp, I think the

- match_re_or_ensure_not_output seems (to me) to imply we're in some way

- the new name match_re_or_ensure_no_output.
-
- Additionally, I found a definite typo in one of the comments that I've
- also fixed.
-
- I also updated some test names. These tests (probably due to copy &

- gdb/python/mi: create MI commands using python
- This commit allows a user to create custom MI commands using Python
- similarly to what is possible for Python CLI commands.
-
- A new subclass of mi_command is defined for Python MI commands,
- mi_command_py. A new file, gdb/python/py-micmd.c contains the logic
- for Python MI commands.
-
- This commit is based on work linked too from this mailing list thread:
-
- https://sourceware.org/pipermail/gdb/2021-November/049774.html
-
- Which has also been previously posted to the mailing list here:
-
- https://sourceware.org/pipermail/gdb-patches/2019-May/158010.html
-
- And was recently reposted here:
-
- https://sourceware.org/pipermail/gdb-patches/2022-January/185190.html
-
- The version in this patch takes some core code from the previously
- posted patches, but also has some significant differences, especially
- after the feedback given here:
-
- https://sourceware.org/pipermail/gdb-patches/2022-February/185767.html
-
- A new MI command can be implemented in Python like this:
-
- class echo_args(gdb.MICommand):
- def invoke(self, args):
- return { 'args': args }
-
- echo_args("-echo-args")
-
- The 'args' parameter (to the invoke method) is a list
- containing (almost) all command line arguments passed to the MI
- command (--thread and --frame are handled before the Python code is
- called, and removed from the args list). This list can be empty if
- the MI command was passed no arguments.
-
- When used within gdb the above command produced output like this:
-
- (gdb)
- -echo-args a b c
- ^done,args=["a","b","c"]
- (gdb)
-
- The 'invoke' method of the new command must return a dictionary. The
- keys of this dictionary are then used as the field names in the mi
- command output (e.g. 'args' in the above).
-
- The values of the result returned by invoke can be dictionaries,
- lists, iterators, or an object that can be converted to a string.
- These are processed recursively to create the mi output. And so, this
- is valid:
-
- class new_command(gdb.MICommand):
- def invoke(self,args):
- return { 'result_one': { 'abc': 123, 'def': 'Hello' },
- 'result_two': [ { 'a': 1, 'b': 2 },
- { 'c': 3, 'd': 4 } ] }
-
- Which produces output like:
-
- (gdb)
- -new-command
- ^done,result_one={abc="123",def="Hello"},result_two=[{a="1",b="2"},{c="3",d="4"}]
- (gdb)
-
- I have required that the fields names used in mi result output must
- match the regexp: "^[a-zA-Z][-_a-zA-Z0-9]*$" (without the quotes).
- This restriction was never written down anywhere before, but seems
- sensible to me, and we can always loosen this rule later if it proves
- to be a problem. Much harder to try and add a restriction later, once
- people are already using the API.
-
- What follows are some details about how this implementation differs
- from the original patch that was posted to the mailing list.
-
- In this patch, I have changed how the lifetime of the Python
- gdb.MICommand objects is managed. In the original patch, these object
- were kept alive by an owned reference within the mi_command_py object.
- As such, the Python object would not be deleted until the
- mi_command_py object itself was deleted.
-
- This caused a problem, the mi_command_py were held in the global mi
- command table (in mi/mi-cmds.c), which, as a global, was not cleared
- until program shutdown. By this point the Python interpreter has
- already been shutdown. Attempting to delete the mi_command_py object
- at this point was causing GDB to try and invoke Python code after
- finalising the Python interpreter, and we would crash.
-
- To work around this problem, the original patch added code in
- python/python.c that would search the mi command table, and delete the
- mi_command_py objects before the Python environment was finalised.
-
- In contrast, in this patch, I have added a new global dictionary to
- the gdb module, gdb._mi_commands. We already have several such global
- data stores related to pretty printers, and frame unwinders.
-
- The MICommand objects are placed into the new gdb.mi_commands
- dictionary, and it is this reference that keeps the objects alive.
- When GDB's Python interpreter is shut down gdb._mi_commands is deleted,
- and any MICommand objects within it are deleted at this point.
-
- This change avoids having to make the mi_cmd_table global, and walk
- over it from within GDB's python related code.
-
- This patch handles command redefinition entirely within GDB's python
- code, though this does impose one small restriction which is not
- present in the original code (detailed below), I don't think this is a
- big issue. However, the original patch relied on being able to
- finish executing the mi_command::do_invoke member function after the
- mi_command object had been deleted. Though continuing to execute a
- member function after an object is deleted is well defined, it is
- also (IMHO) risky, its too easy for someone to later add a use of the
- object without realising that the object might sometimes, have been
- deleted. The new patch avoids this issue.
-
- The one restriction that is added to avoid this, is that an MICommand
- object can't be reinitialised with a different command name, so:
-
- (gdb) python cmd = MyMICommand("-abc")
- (gdb) python cmd.__init__("-def")
- can't reinitialize object with a different command name
-
- This feels like a pretty weird edge case, and I'm happy to live with
- this restriction.
-
- I have also changed how the memory is managed for the command name.
- In the most recently posted patch series, the command name is moved
- into a subclass of mi_command, the python mi_command_py, which
- inherits from mi_command is then free to use a smart pointer to manage
- the memory for the name.
-
- In this patch, I leave the mi_command class unchanged, and instead
- hold the memory for the name within the Python object, as the lifetime
- of the Python object always exceeds the c++ object stored in the
- mi_cmd_table. This adds a little more complexity in py-micmd.c, but
- leaves the mi_command class nice and simple.
-
- Next, this patch adds some extra functionality, there's a
- MICommand.name read-only attribute containing the name of the command,
- and a read-write MICommand.installed attribute that can be used to
- install (make the command available for use) and uninstall (remove the
- command from the mi_cmd_table so it can't be used) the command. This
- attribute will be automatically updated if a second command replaces
- an earlier command.
-
- This patch adds additional error handling, and makes more use the
- gdbpy_handle_exception function.

- gdb/gdbarch: compare some fields against 0 verify_gdbarch
- After the previous commit, which removes the predicate function
- gdbarch_register_type_p, I noticed that the gdbarch->register_type
- field was not checked at in the verify_gdbarch function.
-
- More than not being checked, the field wasn't mentioned at all.
-
- I find this strange, I would expect that every field would at least be
- mentioned - we already generate comments for some fields saying that
- this field is _not_ being checked, so the fact that this field isn't
- being checked looks (to me), like this field is somehow slipping
- through the cracks.
-
- The comment at the top of gdbarch-components.py tries to explain how
- the validation is done. I didn't understand this comment completely,
- but, I think this final sentence:
-
- "Otherwise, the check is done against 0 (really NULL for function
- pointers, but same idea)."
-
- Means that, if non of the other cases apply, then the field should be
- checked against 0, with 0 indicating that the field is invalid (was
- not set by the tdep code). However, this is clearly not being done.
-
- Looking in gdbarch.py at the code to generate verify_gdbarch we do
- find that there is a case that is not handled, the case where the
- 'invalid' field is set true True, but non of the other cases apply.
-
- In this commit I propose two changes:
-
- 1. Handle the case where the 'invalid' field of a property is set to
- True, this should perform a check for the field of gdbarch still
- being set to 0, and
-
- 2. If the if/else series that generates verify_gdbarch doesn't handle
- a property then we should raise an exception. This means that if a
- property is added which isn't handled, we should no longer silently
- ignore it.
-
- After doing this, I re-generated the gdbarch files and saw that the
- following gdbarch fields now had new validation checks:
-
- register_type
- believe_pcc_promotion
- register_to_value
- value_to_register
- frame_red_zone_size
- displaced_step_restore_all_in_ptid
- solib_symbols_extension
-
- Looking at how these are currently set in the various -tdep.c files, I
- believe the only one of these that is required to be set for all
- architectures is the register_type field.
-
- And so, for all of the other fields, I've changed the property
- definition on gdbarch-components.py, setting the 'invalid' field to
- False.
-
- Now, after re-generation, the register_type field is checked against
- 0, thus an architecture that doesn't set_gdbarch_register_type will
- now fail during validation. For all the other fields we skip the
- validation, in which case, it is find for an architecture to not set
- this field.
-
- My expectation is that there should be no user visible changes after
- this commit. Certainly for all fields except register_type, all I've
- really done is cause some extra comments to be generated, so I think
- that's clearly fine.
-
- For the register_type field, my claim is that any architecture that
- didn't provide this would fail when creating its register cache, and I
- couldn't spot an architecture that doesn't provide this hook. As
- such, I think this change should be fine too.

-
- gdb/gdbarch: remove the predicate function for gdbarch_register_type
- I don't believe that the gdbarch_register_type_p predicate is called
- anywhere in GDB, and the gdbarch_register_type function is called
- without checking the gdbarch_register_type_p predicate function
- everywhere it is used, for example in
- init_regcache_descr (regcache.c).
-
- My claim is that the gdbarch_register_type function is required for
- every architecture, and GDB will not work if this function is not
- supplied.
-
- And so, in this commit, I remove the 'predicate=True' from
- gdbarch-components.py for the 'register_type' field, and regenerate
- the gdbarch files.
-
- There should be no user visible changes after this commit.

- Replace deprecated_target_wait_hook by observers
- Commit b60cea7 (Make target_wait options use enum flags) broke
- deprecated_target_wait_hook usage: there's a commit comment telling
- this hook has not been converted.
-
- Rather than trying to mend it, this patch replaces the hook by two
- target_wait observers:
-
- target_pre_wait (ptid_t ptid)
- target_post_wait (ptid_t event_ptid)
-
- Upon target_wait entry, target_pre_wait is notified with the ptid
- passed to target_wait. Upon exit, target_post_wait is notified with
- the event ptid returned by target_wait. Should an exception occur,
- event_ptid is null_ptid.
-
- This change benefits to Insight (out-of-tree): there's no real use of the
- late hook in gdb itself.

- Correctly print subrange types in generic_value_print
- I noticed that generic_value_print assumes that a subrange type is
- always a subrange of an integer type. However, this isn't necessarily
- the case. In Ada, for example, one has subranges of character and
- enumeration types.
-
- This code isn't often exercised, I think, because languages with real
- subrange types tend to implement their own printers. However, it
- still seemed worth fixing.

- [aarch64/arm] Properly extract the return value returned in memory
- When running gdb.cp/non-trivial-retval.exp, the following shows up for
- both aarch64-linux and armhf-linux:
-
- Breakpoint 3, f1 (i1=23, i2=100) at src/gdb/testsuite/gdb.cp/non-trivial-retval.cc:35
- 35 A a;
- (gdb) finish
- Run till exit from #0 f1 (i1=23, i2=100) at src/gdb/testsuite/gdb.cp/non-trivial-retval.cc:35
- main () at /src/gdb/testsuite/gdb.cp/non-trivial-retval.cc:163
- 163 B b = f2 (i1, i2);
- Value returned is $6 = {a = -11952}
- (gdb)
-
- The return value should be {a = 123} instead. This happens because the
- backends don't extract the return value from the correct location. GDB should
- fetch a pointer to the memory location from X8 for aarch64 and r0 for armhf.
-
- With the patch, gdb.cp/non-trivial-retval.exp has full passes on
- aarch64-linux and armhf-linux on Ubuntu 20.04/18.04.
-
- The problem only shows up with the "finish" command. The "call" command
- works correctly and displays the correct return value.
-
- This is also related to PR gdb/28681
- (https://sourceware.org/bugzilla/show_bug.cgi?id=28681) and fixes FAIL's in
- gdb.ada/mi_var_array.exp.
-
- A new testcase is provided, and it exercises GDB's ability to "finish" a
- function that returns a large struct (> 16 bytes) and display the
- contents of this struct correctly. This has always been incorrect for
- these backends, but no testcase exercised this particular scenario.

- Avoid crash with cross-linux core file
- An internal test case creates a core file using gcore, then restarts
- gdb with that core. When run with a cross-linux gdb (in this case,
- x86-64 host with ppc64-linux target), the test fails:
-
- | (gdb) core core
- | [New LWP 18437]
- | warning: `/lib64/libc.so.6': Shared library architecture unknown is not compatible with target architecture powerpc:common64.
- | warning: Could not load shared library symbols for /lib64/ld64.so.1.
- | Do you need "set solib-search-path" or "set sysroot"?
- | ../../src/gdb/gdbarch.c:3388: internal-error: int gdbarch_elf_make_msymbol_special_p(gdbarch*): Assertion `gdbarch != NULL' failed.
- | A problem internal to GDB has been detected,
- | further debugging may prove unreliable.
- | Quit this debugging session? (y or n) y
-
- What's happening here is that the core file lists some shared
- libraries. These aren't available via the solib search path, and so
- gdb finds the local (x86-64) libraries. This is not ideal, but on the
- other hand, it is what was asked for -- while the test does set
- solib-search-path, it does not set the sysroot.
-
- But, because gdb isn't configured to handle these libraries, it
- crashes.
-
- It seems to me that it's better to avoid the crash by having
- solib_bfd_open fail in the case where a library is incompatible. That
- is what this patch does. Now it looks like:
-
- | [New LWP 15488]
- | Error while mapping shared library sections:
- | `/lib64/libc.so.6': Shared library architecture unknown is not compatible with target architecture powerpc:common64.
-
- ... and does not crash gdb.
-
- I don't have a good setup for testing this using dejagnu, so I don't
- know whether an existing gdb test covers this scenario.

- This has confused users multiple times -- see PR gdb/16242, where

- The manual says:

- Re-add zombie leader on exit, gdbserver/linux
- Same as the previous patch, but for GDBserver.
-
- In summary, the current zombie leader detection code in linux-low.cc
- has a race -- if a multi-threaded inferior exits just before
- check_zombie_leaders finds that the leader is now zombie via checking
- /proc/PID/status, check_zombie_leaders deletes the leader, assuming we
- won't get an event for that exit (which we won't in some scenarios,
- but not in this one), which is a false-positive scenario, where the
- whole process is simply exiting. Later when we see the last LWP in
- our list exit, we report that LWP's exit status as exit code, even
- though for the (real) parent process, the exit code that counts is the
- child's leader thread's exit code.
-
- Like for GDB, the solution here is to:
-
- - only report whole-process exit events for the leader.
- - re-add the leader back to the LWP list when we finally see it
- exit.

-
- Re-add zombie leader on exit, gdb/linux
- The current zombie leader detection code in linux-nat.c has a race --
- if a multi-threaded inferior exits just before check_zombie_leaders
- finds that the leader is now zombie via checking /proc/PID/status,
- check_zombie_leaders deletes the leader, assuming we won't get an
- event for that exit (which we won't in some scenarios, but not in this
- one). That might seem mostly harmless, but it has some downsides:
-
- - later when we continue pulling events out of the kernel, we will
- collect the exit event of the non-leader threads, and once we see
- the last lwp in our list exit, we return _that_ lwp's exit code as
- whole-process exit code to infrun, instead of the leader's exit
- code.
-
- - this can cause a hang in stop_all_threads in infrun.c. Say there
- are 2 threads in the process. stop_all_threads stops each of those
- threads, and then waits for two stop or exit events, one for each
- thread. If the whole process exits, and check_zombie_leaders hits
- the false-positive case, linux-nat.c will only return one event to
- GDB (the whole-process exit returned when we see the last thread,
- the non-leader thread, exit), making stop_all_threads hang forever
- waiting for a second event that will never come.
-
- However, in this false-positive scenario, where the whole process is
- exiting, as opposed to just the leader (with pthread_exit(), for
- example), we _will_ get an exit event shortly for the leader, after we
- collect the exit event of all the other non-leader threads. Or put
- another way, we _always_ get an event for the leader after we see it
- become zombie.
-
- I tried a number of approaches to fix this:
-
- #1 - My first thought to address the race was to make GDB always
- report the whole-process exit status for the leader thread, not for
- whatever is the last lwp in the list. We _always_ get a final exit
- (or exec) event for the leader, and when the race triggers, we're not
- collecting it.
-
- #2 - My second thought was to try to plug the race in the first place.
-
- I thought of making GDB call waitpid/WNOHANG for all non-leader
- threads immediately when the zombie leader is detected, assuming there
- would be an exit event pending for each of them waiting to be
- collected. Turns out that that doesn't work -- you can see the leader
- become zombie _before_ the kernel kills all other threads. Waitpid in
- that small time window returns 0, indicating no-event. Thankfully we
- hit that race window all the time, which avoided trading one race for
- another. Looking at the non-leader thread's status in /proc doesn't
- help either, the threads are still in running state for a bit, for the
- same reason.
-
- #3 - My next attempt, which seemed promising, was to synchronously
- stop and wait for the stop for each of the non-leader threads. For
- the scenario in question, this will collect all the exit statuses of
- the non-leader threads. Then, if we are left with only the zombie
- leader in the lwp list, it means we either have a normal while-process
- exit or an exec, in which case we should not delete the leader. If
- _only_ the leader exited, like in gdb.threads/leader-exit.exp, then
- after pausing threads, we will still have at least one live non-leader
- thread in the list, and so we delete the leader lwp. I got this
- working and polished, and it was only after staring at the kernel code
- to convince myself that this would really work (and it would, for the
- scenario I considered), that I realized I had failed to account for
- one scenario -- if any non-leader thread is _already_ stopped when
- some thread triggers a group exit, like e.g., if you have some threads
- stopped and then resume just one thread with scheduler-locking or
- non-stop, and that thread exits the process. I also played with
- PTRACE_EVENT_EXIT, see if it would help in any way to plug the race,
- and I couldn't find a way that it would result in any practical
- difference compared to looking at /proc/PID/status, with respect to
- having a race.
-
- So I concluded that there's no way to plug the race, we just have to
- deal with it. Which means, going back to approach #1. That is the
- approach taken by this patch.

- Fix gdb.threads/current-lwp-dead.exp race
- If we make GDB report the process EXIT event for the leader thread, as
- will be done in a latter patch of this series, then
- gdb.threads/current-lwp-dead.exp starts failing:
-
- (gdb) break fn_return
- Breakpoint 2 at 0x5555555551b5: file /home/pedro/rocm/gdb/build/gdb/testsuite/../../../src/gdb/testsuite/gdb.threads/current-lwp-dead.c, line 45.

- (gdb) FAIL: gdb.threads/current-lwp-dead.exp: continue to breakpoint: fn_return (the program exited)
-
- The inferior exit reported is actually correct. The main thread has
- indeed exited, and that's the thread that has the right exit code to
- report to the user, as that's the exit code that is reported to the
- program's parent. In this case, GDB managed to collect the exit code
- for the leader thread before reaping the other thread, because in
- reality, the testcase isn't creating standard threads, it is using raw
- clone, and the new clones are put in their own thread group.
-
- Fix it by making the main "thread" not exit until the scenario we're
- exercising plays out. Also, run the program to completion for
- completeness.
-
- The original program really wanted the leader thread to exit before
- the fn_return function was reached -- it was important that the
- current thread as pointed by inferior_ptid was gone when infrun got
- the breakpoint event. I've tweaked the testcase to ensure that that
- condition is still held, though it is no longer the main thread that
- exits. This required a bit of synchronization between the threads,
- which required using CLONE_VM unconditionally. The #ifdef guards were
- added as a fix for
- https://sourceware.org/bugzilla/show_bug.cgi?id=11214, though I don't
- think they were necessary because the program is not using TLS. If it
- turns out they were necessary, we can link the testcase with "-z now"
- instead, which was mentioned as an alternative workaround in that
- Bugzilla.

- gdb/testsuite: add new test for comparing char types in Python
- There's an interesting property of the 'char' type in C and C++, the
- three types 'char', 'unsigned char', and 'signed char', are all
- considered distinct.
-
- In contrast, and 'int' is signed by default, and so 'int' and 'signed
- int' are considered the same type.
-
- This commit adds a test to ensure that this edge case is visible to a
- user from Python.
-
- It is worth noting that for any particular compiler implementation (or
- the flags a compiler was invoked with), a 'char' will be either signed
- or unsigned; it has to be one or the other, and a user can access this
- information by using the Type.is_signed property. However, for
- something like function overload resolution, the 'char' type is
- considered distinct from the signed and unsigned variants.
-
- There's no change to GDB with this commit, this is just adding a new
- test to guard some existing functionality.

- Add a new read-only property, Type.is_signed, which is True for signed
- types, and False otherwise.
-
- This property should only be read on types for which Type.is_scalar is
- true, attempting to read this property for non-scalar types will raise
- a ValueError.
-
- I chose 'is_signed' rather than 'is_unsigned' in order to match the
- existing Architecture.integer_type method, which takes a 'signed'
- parameter. As far as I could find, that was the only existing
- signed/unsigned selector in the Python API, so it seemed reasonable to
- stay consistent.

- gdb/mi: add --no-connection to MI -add-inferior command
- Following on from the previous commit, where the -add-inferior command
- now uses the same connection as the current inferior, this commit adds
- a --no-connection option to -add-inferior.
-
- This new option matches the existing option of the same name for the
- CLI version of add-inferior; the new inferior is created with no
- connection.
-
- I've added a new 'connection' field to the MI output of -add-inferior,
- which includes the connection number and short name. I haven't
- included the longer description field, this is the MI after all. My
- expectation would be that if the frontend wanted to display all the
- connection details then this would be looked up from 'info
- connection' (or the MI equivalent if/when such a command is added).
-
- The existing -add-inferior tests are updated, as are the docs.

- gdb/mi: fix regression in mi -add-inferior command
- Prior to the multi-target support commit:
-
- commit 5b6d1e4fa4fc6827c7b3f0e99ff120dfa14d65d2
- Date: Fri Jan 10 20:06:08 2020 +0000
-
- Multi-target support
-
- When a new inferior was added using the MI -add-inferior command, the
- new inferior would be using the same target as all the other
- inferiors. This makes sense, GDB only supported a single target stack
- at a time.
-
- After the above commit, each inferior has its own target stack.
-
- To maintain backward compatibility, for the CLI add-inferior command,
- when a new inferior is added the above commit has the new inferior
- inherit a copy of the target stack from the current inferior.
-
- Unfortunately, this same backward compatibility is missing for the MI.
-
- This commit fixes this oversight.
-
- Now, when the -add-inferior MI command is used, the new inferior will
- inherit a copy of the target stack from the current inferior.

- Fix bug in ada_print_floating
- ada_print_floating rewrites a floating-point string representation to
- conform to Ada syntax. However, if you managed to get a floating
- point error, you might see:
-
- (gdb) print whatever
- $2 = <invalid float valu.0e>
-
- What's happening here is that ada_print_floating doesn't recognize
- this error case, and proceeds to modify the error text.
-
- This patch fixes this problem.

-
- Implement real literal extension for Ada
- Sometimes it is convenient to be able to specify the exact bits of a
- floating-point literal. For example, you may want to set a
- floating-point register to a denormalized value, or to a particular
- NaN.
-
- In C, you can do this by combining the "{}" cast with an array
- literal, like:
-
- (gdb) p {double}{0x576488BDD2AE9FFE}
- $1 = 9.8765449999999996e+112
-
- This patch adds a somewhat similar idea to Ada. It extends the lexer
- to allow "l" and "f" suffixes in a based literal. The "f" indicates a
- floating-point literal, and the "l"s control the size of the
- floating-point type.
-
- Note that this differs from Ada's based real literals. I believe
- those can also be used to control the bits of a floating-point value,
- but they are a bit more cumbersome to use (simplest is binary but
- that's also very lengthy). Also, these aren't implemented in GDB.
-
- I chose not to allow this extension to work with based integer
- literals with exponents. That didn't seem very useful.
-
-2022-03-07 Tom Tromey <tromey@adacore.com>
-
- Fix Ada integer literals with exponents
- While working on another patch, I noticed that Ada integer literals
- with exponents did not work. For example, with one form you get an
- error:
-
- (gdb) print 8e2
- Invalid digit `e' in based literal
-
- And with another form you get an incorrect value:
-
- (gdb) print 16#8#e2
- $2 = 8
-
- This patch fixes the bugs and adds tests.

- Fix gdb.ada/arrayptr.exp results

-
- Handle non-ASCII identifiers in Ada
- Ada allows non-ASCII identifiers, and GNAT supports several such
- encodings. This patch adds the corresponding support to gdb.
-
- GNAT encodes non-ASCII characters using special symbol names.
-
- For character sets like Latin-1, where all characters are a single
- byte, it uses a "U" followed by the hex for the character. So, for
- example, thorn would be encoded as "Ufe" (0xFE being lower case
- thorn).
-
- For wider characters, despite what the manual says (it claims
- Shift-JIS and EUC can be used), in practice recent versions only
- support Unicode. Here, characters in the base plane are represented
- using "Wxxxx" and characters outside the base plane using
- "WWxxxxxxxx".
-
- GNAT has some further quirks here. Ada is case-insensitive, and GNAT
- emits symbols that have been case-folded. For characters in ASCII,
- and for all characters in non-Unicode character sets, lower case is
- used. For Unicode, however, characters that fit in a single byte are
- converted to lower case, but all others are converted to upper case.
-
- Furthermore, there is a bug in GNAT where two symbols that differ only
- in the case of "Y WITH DIAERESIS" (and potentially others, I did not
- check exhaustively) can be used in one program. I chose to omit
- handling this case from gdb, on the theory that it is hard to figure
- out the logic, and anyway if the bug is ever fixed, we'll regret
- having a heuristic.
-
- This patch introduces a new "ada source-charset" setting. It defaults
- to Latin-1, as that is GNAT's default. This setting controls how "U"
- characters are decoded -- W/WW are always handled as UTF-32.
-
- The ada_tag_name_from_tsd change is needed because this function will
- read memory from the inferior and interpret it -- and this caused an
- encoding failure on PPC when running a test that tries to read
- uninitialized memory.
-
- This patch implements its own UTF-32-based case folder. This avoids
- host platform quirks, and is relatively simple. A short Python
- program to generate the case-folding table is included. It simply
- relies on whatever version of Unicode is used by the host Python,
- which seems basically acceptable.
-
- Test cases for UTF-8, Latin-1, and Latin-3 are included. This
- exercises most of the new code paths, aside from Y WITH DIAERESIS as
- noted above.

-
- Define HOST_UTF32 in charset.h
- rust-parse.c has a #define for the host-specific UTF-32 charset name.
- A later patch needs the same thing, so this patch moves the definition
- to charset.h for easier reuse.

-
- Let phex and phex_nz handle sizeof_l==1
- Currently, neither phex nor phex_nz handle sizeof_l==1 -- they let
- this case fall through to the default case. However, a subsequent
- patch in this series needs this case to work correctly.
-
- I looked at all calls to these functions that pass a 1 for the
- sizeof_l parameter. The only such case seems to be correct with this
- change.
-
-2022-03-07 Tom Tromey <tromey@adacore.com>
-
- Don't pre-size result string in ada_decode
- Currently, ada_decode pre-sizes the output string, filling it with 'X'
- characters. However, it's a bit simpler and more flexible to let
- std::string do the work here, and simply append characters to the
- string as we go. This turns out to be useful for a subsequent patch.
-
- Simplify a regular expression in ada-lex.l
- ada-lex.l uses "%option case-insensitive", so there is no need for
- regular expressions to match upper case.

- Correct issues with INSN2_ALIAS annotation for branch instructions:
-
- - regular MIPS BEQZ/L and BNEZ/L assembly instructions are idioms for
- BEQ/L and BNE/L respectively with the `rs' operand equal to $0,
-
- - microMIPS 32-bit BEQZ and BNEZ assembly instructions are idioms for

-
- - regular MIPS BAL assembly instruction is an idiom for architecture
- levels of up to the MIPSr5 ISA and a machine instruction on its own
- from the MIPSr6 ISA up.

- Add missing annotation to BEQZ/L and BNEZ/L accordingly then and add a

- gdb: constify parameter of value_copy
- In a following patch, I have a const value I want to copy using a
- value_copy. However, value_copy takes a non-const source value, at the
- moment. Change the paramter to be const,
-
- If the source value is not lazy, we currently call
- value_contents_all_raw, which calls allocate_value_contents, to get a
- view on the contents. They both take a non-const value, that's a
- problem. My first attempt at solving it was to add a const version of
- value_contents_all_raw, make allocate_value_contents take a const value,
- and either:
-
- - make value::contents mutable
- - make allocate_value_contents cast away the const
-
- The idea being that allocating the value contents buffer does modify the
- value at the bit level, but logically that doesn't change its state.
-
- That was getting a bit complicated, so what I ended up doing is make
- value_copy not call value_contents_all_raw. We know at this point that
- the value is not lazy, so value::contents must have been allocate
- already.

- Rewrite make-target-delegates in Python
- I think gdb is probably better off having fewer languages involved
- when generating code. 'sh' is unavoidable for build-time generation,
- but for other things, let's use Python.
-
- This rewrites make-target-delegates in Python. I've stuck pretty
- closely to the original code in this rewrite, so it may look slightly
- weird from a Python perspective.
-
- The only output difference is that a copyright header is now
- generated, using the code introduced in the previous patch.
-
- make-target-delegates.py is simpler to invoke, as it knows the correct
- input file to scan and it creates the output file itself.

- Some "distclean" fixes in gdb
- PR build/12440 points out that "make distclean" is broken in gdb.
- Most of the breakage comes from other projects in the tree, but we can
- fix some of the issues, which is what this patch does.
-
- Note that the yacc output files, like c-exp.c, are left alone. In a
- source distribution, these are included in the tarball, and if the
- user builds in-tree, we would not want to remove them.
-
- While that seems a bit obscure, it seems to me that "distclean" is
- only really useful for in-tree builds anyway -- out-of-tree I simply
- delete the entire build directory and start over.

- gdb: testsuite: fix wrong expected result in attach-pie-noexec.exp
- If /proc/sys/kernel/yama/ptrace_scope is 1, when execute the test case
- gdb.base/attach-pie-noexec.exp without superuser, the gdb.log shows the
- following info:
-
- (gdb) attach 6500
- Attaching to process 6500
- ptrace: Operation not permitted.
- (gdb) PASS: gdb.base/attach-pie-noexec.exp: attach
-
- It is obviously wrong, the expected result should be UNSUPPORTED in such
- a case.
-
- It is better to make can_spawn_for_attach to return false for this case.
- It would have to setup a small test program, compile it to exec, spawn it
- and try to attach to it.
-
- With this patch, we can see "Operation not permitted" in the log info,
- and then we can do the following processes to test:
- (1) set ptrace_scope as 0
- $ echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
- $ make check-gdb TESTS="gdb.base/attach-pie-noexec.exp"
- (2) use sudo

- Fix "spawn id XYZ not open" errors in gdb.mi/mi-exec-run.exp
- Running mi-exec-run.exp on native-extended-gdbserver/-m{32,64}
- causes several Tcl errors to appear. For example,
-
- (gdb)
- ERROR: : spawn id exp20 not open
- while executing
- "expect {
- -i exp11 -timeout 10
- -i "$inferior_spawn_id"
- -re ".*Cannot exec.*Permission denied" {
- set saw_perm_error 1
- verbose -log "saw..."
- ("uplevel" body line 1)
- invoked from within
- "uplevel $body" NONE : spawn id exp20 not open
- UNRESOLVED: gdb.mi/mi-exec-run.exp: inferior-tty=separate: mi=separate: force-fail=1: run failure detected (eof)
-
- This is happening because of the way this test is implemented:
-
- while {1} {
- gdb_expect {
- -i "$inferior_spawn_id"
- -re ".*Cannot exec.*Permission denied" {
- set saw_perm_error 1
- verbose -log "saw mi error"
- }
- -i "$gdb_spawn_id"
- -re "\\^error,msg=\"During startup program exited with code 127" {
- set saw_mi_error 1
- verbose -log "saw mi error"
- }
- # and so on
- }
- }
-
- The first time this loop is executed, `inferior_spawn_id' is valid. When the
- first branch of the expect statement is reached, gdbserver has exited, closing
- the spawn_id. Since we haven't seen the gdb-side error yet, the loop is executed
- again. The first branch now refers to a non-existent spawn_id, leading to the error.
-
- This can be fixed by using exp_continue to loop in expect instead of looping around
- expect, which is the approach I have used[1]. Note I've had to update the expected
- message for the "During startup..." error message when running with gdbserver.
-
- One other small change I've made is to add a log entry which spills the values of
- the two variables, saw_mi_error and saw_perm_error (and updated the log output
- for the later). This should make the log output clearer about why the test failed.
-
- With this patch installed, all the ERRORs disappear, leaving previously masked
- FAILs (which I have not attempted to fix).
-
- [1] Anyone know why this test doesn't simply use gdb_test_multiple? I can only
- assume that it was intentionally written this way, and I've modified the code with
- that assumption. I have tested a version using gdb_test_multiple, and that appears
- to work fine, too, if that is preferred. [It still employs exp_continue to fix the
- spawn_id errors.]

- Handle multi-byte bracket sequences in Ada lexer

- Handle 'QWW' encoding case in Ada enums
- In Ada, an enum can contain character literals. GNAT encodes these
- values in a special way. For example, the Unicode character U+0178
- would be represented as 'QW0178' in the DWARF:
-
- <3><112f>: Abbrev Number: 2 (DW_TAG_enumerator)
- <1130> DW_AT_name : (indirect string, offset: 0x19ff): QW0178
- <1134> DW_AT_const_value : 2
-
- gdb handles this reasonably well, but failed to handle the 'QWW'
- encoding, which is used for characters outside the base plane.
-
- Also, while working on this, I noticed that gdb will print the decimal
- value for an enum character constant:
-
- (gdb) print Char_X
- $2 = 1 'x'
-
- This is a nice feature, IMO, because in this situation the 'x' enum
- constant does not have its usual decimal value -- it has the value
- that's assigned based on the enumeration type.
-
- However, gdb did not do this when it decided to print the constant
- using the bracket notation:
-
- (gdb) print Char_Thorn
- $3 = ["de"]
-
- This patch changes gdb to print the decimal value here as well, and to
- put the bracket notation in single quotes -- otherwise gdb will be
- printing something that it can't then read. Now it looks like:
-
- (gdb) print Char_Thorn
- $3 = 4 '["de"]'
-
- Note that gdb can't read longer bracket notations, like the other ones
- printed in this test case:
-
- (gdb) print Char_King
- $4 = 3 '["01fa00"]'
-
- While I think this is a bug, I plan to fix it separately.
-
- Finally, in the new test case, the copyright dates are chosen this way
- because this all started as a copy of an existing test.

- gdb/python: Add gdb.InferiorThread.details attribute

- As the string returned by target_extra_thread_info is unstructured,

- Print MI prompt on interrupted command
- Joel noticed that if the remote dies unexpectedly during a command --
- you can simulate this by using "continue" and then killing gdbserver
- -- then the CLI will print a new prompt, but MI will not. Later, we
- found out that this was also filed in bugzilla as PR mi/23820.
-
- The output looks something like this:
-
- | (gdb)
- | cont
- | &"cont\n"
- | ~"Continuing.\n"
- | ^running
- | *running,thread-id="all"
- | (gdb)
- | [... some output from GDB during program startup...]
- | =thread-exited,id="1",group-id="i1"
- | =thread-group-exited,id="i1"
- | &"Remote connection closed\n"
-
- Now, what about that "(gdb)" in the middle?
-
- That prompt comes from this questionable code in
- mi-interp.c:mi_on_resume_1:
-
- /* This is what gdb used to do historically -- printing prompt
- even if it cannot actually accept any input. This will be
- surely removed for MI3, and may be removed even earlier. */
- if (current_ui->prompt_state == PROMPT_BLOCKED)
- fputs_unfiltered ("(gdb) \n", mi->raw_stdout);
-
- ... which seems like something to remove. But maybe the intent here
- is that this prompt is sufficient, and MI clients must be ready to
- handle output coming after a prompt. On the other hand, if this code
- *is* removed, then nothing would print a prompt in this scenario.
-
- Anyway, the CLI and the TUI handle emitting the prompt here by hooking
- into gdb::observers::command_error, but MI doesn't install an observer
- here.
-
- This patch adds the missing observer and arranges to show the MI
- prompt. Regression tested on x86-64 Fedora 34.
-
- It seems like this area could be improved a bit, by having
- start_event_loop call the prompt-displaying code directly, rather than
- indirecting through an observer. However, I haven't done this.

- Support template lookups in strncmp_iw_with_mode
- This patch adds support for wild template parameter list matches, similar
- to how ABI tags or function overloads are now handled.
-
- With this patch, users will be able to "gloss over" the details of matching
- template parameter lists. This is accomplished by adding (yet more) logic
- to strncmp_iw_with_mode to skip parameter lists if none is explicitly given
- by the user.
-
- Here's a simple example using gdb.linespec/cpls-ops.exp:
-
- Before
- ------
- (gdb) ptype test_op_call
- type = struct test_op_call {
- public:
- void operator()(void);
- void operator()(int);
- void operator()(long);
- void operator()<int>(int *);
- }
- (gdb) b test_op_call::operator()
- Breakpoint 1 at 0x400583: test_op_call::operator(). (3 locations)
- (gdb) i b
- Num Type Disp Enb Address What
- 1 breakpoint keep y <MULTIPLE>
- 1.1 y 0x400583 in test_op_call::operator()(int)
- at cpls-ops.cc:43
- 1.2 y 0x40058e in test_op_call::operator()()
- at cpls-ops.cc:47
- 1.3 y 0x40059e in test_op_call::operator()(long)
- at cpls-ops.cc:51
-
- The breakpoint at test_op_call::operator()<int> was never set.
-
- After
- -----
- (gdb) b test_op_call::operator()
- Breakpoint 1 at 0x400583: test_op_call::operator(). (4 locations)
- (gdb) i b
- Num Type Disp Enb Address What
- 1 breakpoint keep y <MULTIPLE>
- 1.1 y 0x400583 in test_op_call::operator()(int)
- at cpls-ops.cc:43
- 1.2 y 0x40058e in test_op_call::operator()()
- at cpls-ops.cc:47
- 1.3 y 0x40059e in test_op_call::operator()(long)
- at cpls-ops.cc:51
- 1.4 y 0x4008d0 in test_op_call::operator()<int>(int*)
- at cpls-ops.cc:57
-
- Similar to how scope lookups work, passing "-qualified" to the break command
- will cause a literal lookup of the symbol. In the example immediately above,
- this will cause GDB to only find the three non-template functions.

- PR fortran/28801 points out a gdb crash that can be provoked by
- certain Fortran code. The bug is that f77_get_upperbound assumes the
- property is either a constant or undefined, but in this case it is
- PROP_LOCEXPR.
-
- This patch fixes the crash by making this function (and the
- lower-bound one as well) do the correct check before calling
- 'const_val'.
-
- Thanks to Andrew for writing the test case.

- Revert "do_target_wait_1: Clear TARGET_WNOHANG if the target isn't async."
- Commit 14b3360508b1 ("do_target_wait_1: Clear
- TARGET_WNOHANG if the target isn't async.") broke some multi-target
- tests, such as gdb.multi/multi-target-info-inferiors.exp. The symptom
- is that execution just hangs at some point. What happens is:
-
- 1. One remote inferior is started, and now sits stopped at a breakpoint.
- It is not "async" at this point (but it "can async").
-
- 2. We run a native inferior, the event loop gets woken up by the native
- target's fd.
-
- 3. In do_target_wait, we randomly choose an inferior to call target_wait
- on first, it happens to be the remote inferior.
-
- 4. Because the target is currently not "async", we clear
- TARGET_WNOHANG, resulting in synchronous wait. We therefore block
- here:

- Before the aforementioned commit, we would not have cleared
- TARGET_WNOHANG, the remote target's wait would have returned nothing,
- and we would have consumed the native target's event.
-
- After applying this revert, the testsuite state looks as good as before
- for me on Ubuntu 20.04 amd64.

- gdb/darwin: skip over WIFSTOPPED wait4 status
- On modern Darwin's, there appears to be a new circumstance in which a
- MACH_NOTIFY_DEAD_NAME message can be received, and which was not
- previously accounted for: to signal the WIFSTOPPED condition in the
- debuggee. In that case the debuggee is not dead yet (and in fact,
- counting it as dead would cause a zombie leak - A process in such a
- state reparents to PID 1, but cannot be killed).
-
- - Read and ignore such messages (counting on the next exception message
- to let us know of the inferior's new state again)
- - Refactor logging so as to clearly distinguish between the
- MACH_NOTIFY_DEAD_NAME cases (WIFEXITED, WIFSTOPPED, signal, or
- something else), and warn in the last case

- gdb/linux-tdep: move "Perms" column right
- Commit 29ef4c0699e1 ("gdb/linux-tdep.c: Add Perms to the 'info proc
- mappings' output") has broken test gdb.base/info-proc.exp on Linux,
- because it changes the output of "info proc mappings" in a way that the
- test does not expect (my bad for not testing before pushing).
-
- I looked at how FreeBSD handles this, since I remembered it did show
- permission flags. It looks like this:
-
- Start Addr End Addr Size Offset Flags File
- 0x200000 0x243000 0x43000 0x0 r-- CN-- /usr/local/bin/tmux
-
- (I think that `Flags` and the flags not being aligned is not
- intentional)
-
- The test passes on FreeBSD, because the test looks for four hex numbers
- in a row and ignores the rest:
-
- ".*Mapped address spaces:.*${hex}${ws}${hex}${ws}${hex}${ws}${hex}.*"
-
- I suggest fixing it on Linux by moving the flags column to the same
- place as in the FreeBSD output. It makes things a bit more consistent
- between OSes, and we don't have to touch the test.
-
- At the same time, make use of the actual length of the permission's
- string to specify the number of characters to print.
-
- Before this patch, the output looks like:
-
- Start Addr End Addr Perms Size Offset objfile
- 0x55dd4b544000 0x55dd4b546000 r--p 0x2000 0x0 /usr/bin/sleep
-
- and after, it looks like:
-
- Start Addr End Addr Size Offset Perms objfile
- 0x5622ae662000 0x5622ae664000 0x2000 0x0 r--p /usr/bin/sleep

- for (a non-NULL terminated view on a string). No changes in behavior

- Fix bug in C++ overload resolution
- PR c++/28901 points out a bug in C++ overload resolution. When
- comparing two overloads, one might be better than the other for
- certain parameters -- but, if that one also has some invalid
- conversion, then it should never be considered the better choice.
- Instead, a valid-but-not-apparently-quite-as-good overload should be
- preferred.
-
- This patch fixes this problem by changing how overload comparisons are
- done. I don't believe it should affect any currently valid overload
- resolution; nor should it affect resolutions where all the choices are
- equally invalid.

- gdb/linux-tdep.c: Add Perms to the 'info proc mappings' output
- Fixes #28914 and so it adds a 'Perms' (permissions) column to the
- 'info proc mappings' command output. This will allow users to know
- the memory pages permissions right away from GDB instead of having
- to fetch them from the /proc/$pid/maps file (which is also what GDB
- does internally, but it just did not print that column).

- NEWS: Note that the FreeBSD async target supports async mode.
-
-2022-02-22 John Baldwin <jhb@FreeBSD.org>
-
- inf-ptrace: Add an event_pipe to be used for async mode in subclasses.
- Subclasses of inf_ptrace_target have to opt-in to using the event_pipe
- by implementing the can_async_p and async methods. For subclasses
- which do this, inf_ptrace_target provides is_async_p, async_wait_fd
- and closes the pipe in the close target method.
-
- inf_ptrace_target also provides wrapper routines around the event pipe
- (async_file_open, async_file_close, async_file_flush, and
- async_file_mark) for use in target methods such as async.
- inf_ptrace_target also exports a static async_file_mark_if_open
- function which can be used in SIGCHLD signal handlers.
-
-2022-02-22 John Baldwin <jhb@FreeBSD.org>
-
- Enable async mode in the target in attach_cmd.
- If the attach target supports async mode, enable it after the
- attach target's ::attach method returns.
-
- fbsd-nat: Return nullptr rather than failing ::thread_name.
- ptrace on FreeBSD cannot be used against running processes and instead
- fails with EBUSY. This meant that 'info threads' would fail if any of
- the threads were running (for example when using schedule-multiple=on
- in gdb.base/fork-running-state.exp). Instead of throwing errors, just
- return nullptr as no thread name is better than causing info threads to
- fail completely.
-
-2022-02-22 John Baldwin <jhb@FreeBSD.org>
-
- fbsd-nat: Various cleanups to the ::resume entry debug message.
- Move the message from 'show debug fbsd-lwp' to 'show debug fbsd-nat'
- since it is helpful for debugging async target support and not just
- LWP support.
-
- Use target_pid_to_str to format the ptid and log the step and signo
- arguments.
-

-
- fbsd-nat: Include ptrace operation in error messages.
-
-2022-02-22 John Baldwin <jhb@FreeBSD.org>
-
- fbsd-nat: Implement async target support.
- This is a fairly simple version of async target support.
-
- Synchronous mode still uses blocking waitpid() calls in
- inf_ptrace::wait() unlike the Linux native target which always uses
- WNOHANG and uses sigsuspend() for synchronous operation.
-
- Asynchronous mode registers an event pipe with the core as a file
- handle and writes to the pipe when SIGCHLD is raised. TARGET_WNOHANG
- is handled by inf_ptrace::wait().
-
-2022-02-22 John Baldwin <jhb@FreeBSD.org>
-
- inf-ptrace: Support async targets in inf_ptrace_target::wait.
- - Handle TARGET_WNOHANG by passing WNOHANG to waitpid and returning
- TARGET_WAITKIND_IGNORE if there are no events to report.
-
- - Handle a race in async mode where SIGCHLD might signal the event
- pipe for an event that has already been reported. If the event was
- the exit of the last child process, waitpid() will fail with ECHILD
- rather than returning a pid of 0. For this case, return
- TARGET_WAITKIND_NO_RESUMED.
-
-2022-02-22 John Baldwin <jhb@FreeBSD.org>
-
- inf-ptrace: Return an IGNORE event if waitpid() fails.
- Previously this returned a TARGET_WAITKIND_SIGNALLED event for
- inferior_ptid. However, inferior_ptid is invalid during ::wait()
- methods after the multi-target changes, so this was triggering an
- assertion further up the stack.
-
- do_target_wait_1: Clear TARGET_WNOHANG if the target isn't async.
- Previously, TARGET_WNOHANG was cleared if a target supported async
- mode even if async mode wasn't currently enabled. This change only
- permits TARGET_WNOHANG if async mode is enabled.
-
-2022-02-22 John Baldwin <jhb@FreeBSD.org>
-
- Don't enable async mode at the end of target ::resume methods.
- Now that target_resume always enables async mode after target::resume
- returns, these calls are redundant.
-
- The other place that target resume methods are invoked outside of
- target_resume are as the beneath target in record_full_wait_1. In
- this case, async mode should already be enabled when supported by the
- target before the resume method is invoked due to the following:
-
- In general, targets which support async mode run as async until
- ::wait returns TARGET_WAITKIND_NO_RESUMED to indicate that there are
- no unwaited for children (either they have exited or are stopped).
- When that occurs, the loop in wait_one disables async mode. Later
- if a stopped child is resumed, async mode is re-enabled in
- do_target_resume before waiting for the next event.
-
- In the case of record_full_wait_1, this function is invoked from the
- ::wait target method when fetching an event. If the underlying
- target supports async mode, then an earlier call to do_target_resume
- to resume the child reporting an event in the loop in
- record_full_wait_1 would have already enabled async mode before
- ::wait was invoked. In addition, nothing in the code executed in
- the loop in record_full_wait_1 disables async mode. Async mode is
- only disabled higher in the call stack in wait_one after ::wait
- returns.
-
- It is also true that async mode can be disabled by an
- INF_EXEC_COMPLETE event passed to inferior_event_handle, but all of
- the places that invoke that are in the gdb core which is "above" a
- target ::wait method.
-
- Note that there is an earlier call to enable async mode in
- linux_nat_target::resume. That call also marks the async event pipe
- to report an existing event after enabling async mode, so it needs to
- stay.
-
-2022-02-22 John Baldwin <jhb@FreeBSD.org>
-
- Enable async mode on supported targets in target_resume.
- Enabling async mode above the target layer removes duplicate code in
- ::resume methods of async-capable targets. Commit 5b6d1e4fa4f
- ("Multi-target support") enabled async mode in do_target_resume after
- target_resume returns which is a step in this direction. However,
- other callers of target_resume such as target_continue do not enable
- async mode. Rather than enabling async mode in each of the callers
- after target_resume returns, enable async mode at the end of
- target_resume.

- This pulls out the implementation of an event pipe used to implement

- gdb: fix detection of compilation and linking flags for source-highlight
- Currently there are two problems with the detection of
- source-highlight via pkg-config in GDB's configure script:
-
- 1. The LDFLAGS variable is used to pass the 'pkg-config --libs' output
- to AC_LINK_IFELSE, which results in the "-L/some/path
- -lsource-highlight" preceding the conftest.cpp, which can result in a
- failure to find symbols referenced in conftest.cpp, if the linker is
- using --as-needed by default.
-
- 2. The CFLAGS variable is used to pass the 'pkg-config --cflags'
- output to AC_LINK_IFELSE. However, as the current language is C++,
- AC_LINK_IFELSE will actuall use CXXFLAGS, not CFLAGS, so any flags
- returned from pkg-config will not be seen.
-
- This patch fixes both of these mistakes, allowing GDB to correctly
- configure and build using source-highlight installed into a custom
- prefix, e.g. ~/opt/gdb-git (because the system version of
- source-highlight is too old).

- gdb/testsuite: relax pattern in new gdb.mi/mi-multi-commands.exp test
- I saw some failures in the test gdb.mi/mi-multi-commands.exp that I
- added recently. This test was added in commit:
-
- commit d08cbc5d3203118da5583296e49273cf82378042
- Date: Wed Dec 22 12:57:44 2021 +0000
-
- gdb: unbuffer all input streams when not using readline
-
- The failures I see only occurred when my machine was very heavily
- loaded.
-
- In this test I send multiple commands from dejagnu to gdb with a
- single send_gdb call. In a well behaving world what I want to happen
- is that the gdb console sees both commands arrive and echos the text
- of those commands. Then gdb starts processing the first command,
- prints the result, and then processes the second command, and prints
- the result.
-
- However, what I saw in my loaded environment was that only after
- sending the two commands, only the first command was echoed to gdb's
- terminal. Then gdb started processing the first command, and started
- to write the output. Now, mixed in with the first command output, the
- second command was echoed to gdb's terminal. Finally, gdb would
- finish printing the first command output, and would read and handle
- the second command.
-
- This mixing of command echoing with the first command output was
- causing the test matching patterns to fail.
-
- In this commit I change the command I use in the test from a CLI
- command to an MI command, this reduces the number of lines of output
- that come from the test, CLI commands sent through the MI interpreter
- are echoed back like this:
-
- (gdb)
- set $a = "FIRST COMMAND"
- &"set $a = \"FIRST COMMAND\"\n"
- ^done
- (gdb)
-
- While this is not the case for true MI command:
-
- (gdb)
- -data-evaluate-expression $a
- ^done,value="\"FIRST COMMAND\""
- (gdb)
-
- Less output makes for simpler patterns to match against.
-
- Next, when sending two command to gdb I was previously trying to spot
- the output of the first command followed by the prompt with nothing
- between. This is not really needed, for the first command I can look
- for just the ^done,value="\"FIRST COMMAND\"" string, then I can start
- looking for the output of the second command.
-
- So long as the second pattern matches up to the gdb prompt, then I can
- be sure than nothing is left over in the expect buffer to muck up
- later matches.
-
- As to see the second command output gdb must have read in the second
- command, the second command output never suffers from the corruption
- that the first command output does.
-
- Since making this change, I've not seen a failure in this test.

- gdb: avoid nullptr access in dbxread.c from read_dbx_symtab
- This fixes a GDB crash reported in bug pr/28900, related to reading in
- some stabs debug information.
-
- In this commit my goal is to stop GDB crashing. I am not trying to
- ensure that GDB makes the best possible use of the available stabs
- debug information. At this point I consider stabs a legacy debug
- format, with only limited support in GDB.
-
- So, the problem appears to be that, when reading in the stabs data, we
- need to find a N_SO entry, this is the entry that defines the start of
- a compilation unit (or at least the location of a corresponding source
- file).
-
- It is while handling an N_SO that GDB creates a psymtab to hold the
- incoming debug information (symbols, etc).
-
- The problem we hit in the bug is that we encounter some symbol
- information (an N_PC entry) outside of an N_SO entry - that is we find
- some symbol information that is not associated with any source file.
-
- We already have some protection for this case, look (in
- read_dbx_symtab) at the handling of N_PC entries of type 'F' and 'f',
- if we have no psymtab (the pst variable is nullptr) then we issue a
- complaint. However, for whatever reason, in both 'f' and 'F'
- handling, there is one place where we assume that the pst
- variable (the psymtab) is not nullptr. This is a mistake.
-
- In this commit, I guard these two locations (in 'f' and 'F' handling)
- so we no longer assume pst is not nullptr.
-
- While I was at it, I audited all the other uses of pst in
- read_dbx_symtab, and in every potentially dangerous case I added a
- nullptr check, and issue a suitable complaint if pst is found to be
- nullptr.
-
- It might well be true that we could/should do something smarter if we
- see a debug symbol outside of an N_SO entry, and if anyone wanted to
- do that work, they're welcome too. But this commit is just about
- preventing the nullptr access, and the subsequent GDB crash.
-
- I don't have any tests for this change, I have no idea how to generate
- weird stabs data for testing. The original binary from the bug report
- now loads just fine without GDB crashing.

- gdb: Only paginate for filtered output in fputs_maybe_filtered
- A have had situation where a unfiltered output (done using
- fputs_unfiltered) ended up triggering pagination. The backtrace for this was:

- ...

- #25 0x0000558394b67b57 in gdb_do_one_event () at ../../gdbsupport/event-loop.cc:216

- ...
-
- This comes from what appears to be a oversight in fputs_maybe_filtered. This
- function has a FILTER parameter which if true makes the function pause after
- every screenful (i.e. triggers pagination).
-
- The filter parameter is correctly used to guard the first place where
- prompt_for_continue. There is a second place in the function which can call
- prompt_for_continue, but is currently unguarded. I believe that this is an
- oversight, this patch fixes that.
-
- Tested on Linux-x86_64, no regression observed.

- gdb/darwin: remove not-so-harmless spurious call to `wait4`
- As seen in https://sourceware.org/bugzilla/show_bug.cgi?id=24069 this
- code will typically wait4() a second time on the same process that was
- already wait4()'d a few lines above. While this used to be
- harmless/idempotent (when we assumed that the process already exited),
- this now causes a deadlock in the WIFSTOPPED case.
-
- The early (~2019) history of bug #24069 cautiously suggests to use
- WNOHANG instead of outright deleting the call. However, tests on the
- current version of Darwin (Big Sur) demonstrate that gdb runs just fine
- without a redundant call to wait4(), as would be expected.
- Notwithstanding the debatable value of conserving bug compatibility with
- an OS release that is more than a decade old, there is scant evidence of
- what that double-wait4() was supposed to achieve in the first place - A
- cursory investigation with `git blame` pinpoints commits bb00b29d7802
- and a80b95ba67e2 from the 2008-2009 era, but fails to answer the
- "why" question conclusively.

- gdb: Respect the DW_CC_nocall attribute
- It is possible for a compiler to optimize a function in a such ways that
- the function does not follow the calling convention of the target. In
- such situation, the compiler can use the DW_AT_calling_convention
- attribute with the value DW_CC_nocall to tell the debugger that it is
- unsafe to call the function. The DWARF5 standard states, in 3.3.1.1:
-
- > If the value of the calling convention attribute is the constant
- > DW_CC_nocall, the subroutine does not obey standard calling
- > conventions, and it may not be safe for the debugger to call this
- > subroutine.
-
- Non standard calling convention can affect GDB's assumptions in multiple
- ways, including how arguments are passed to the function, how values are
- returned, and so on. For this reason, it is unsafe for GDB to try to do
- the following operations on a function with marked with DW_CC_nocall:
-
- - call / print an expression requiring the function to be evaluated,
- - inspect the value a function returns using the 'finish' command,
- - force the value returned by a function using the 'return' command.
-
- This patch ensures that if a command which relies on GDB's knowledge of
- the target's calling convention is used on a function marked nocall, GDB
- prints an appropriate message to the user and does not proceed with the
- operation which is unreliable.
-
- Note that it is still possible for someone to use a vendor specific
- value for the DW_AT_calling_convention attribute for example to indicate
- the use of an alternative calling convention. This commit does not
- prevent this, and target dependent code can be adjusted if one wanted to
- support multiple calling conventions.
-
- Tested on x86_64-Linux, with no regression observed.

- Calls to basename were added here as part of commit
- e1e1ae6e9b5e "sim: testsuite: fix objdir handling", but that
- commit missed adding "#include <libgen.h>" or the equivalent
- GNU extension, see basename(3). Fixing that shows a logical
- error in the change to openpf1.c; the non-/-prefixed
- code-path was changed instead of the "/"-prefixed code-path,
- which is the one executed after that commit.
-
- For "newlib" these tests failed linking after that commit.
- Recent newlib has the (asm-renamed) GNU-extension-variant of
- basename, but we're better off not using it at all.
-
- Unfortunately, compilation failures for C tests run by the
- machinery in c.exp are currently just marked "unresolved",
- in contrast to C and assembler tests run by calling
- run_sim_test.
-
- The interaction of calling with the full program-path vs.
- use of --sysroot exposes a consistency problem: when
- --sysroot is used, argv[0] isn't the path by which the
- program can find itself. It's undecided whether argv[0] for
- the program running in the simulator should be edited
- (related to the naked argument to the simulator before
- passing on to the simulated program) to remove a leading
- --sysroot. Either way, such a change would be out of scope

- sim: Fix use of out-of-tree assembler and linker when testing
- With commit 7a259895bb2d "sim: testsuite: expand arch specific
- toolchain settings", trying to use out-of-tree ld and as at test-time
- broke for the "primary target", like when testing a release-tarball.
-
- Subsequent to that commit, all assembler tests without in-tree-built
- tools FAIL, getting errors when trying to call
- $(abs_builddir)/../gas/as-new. But, that isn't the actual culprint;
- it's actually it's its immediate predecessor, commit 8996c21067373
- "sim: testsuite: setup per-port toolchain settings for multitarget
- build", which hardcodes in-tree-paths to those tools instead of
- considering e.g. $(<X>_FOR_TARGET), the preferred overridable variable
- for single-target builds, as set up by the toplevel Makefile.
-
- This commit calls GCC_TARGET_TOOL (a deceptive name; gcc-specific
- features aren't used) from toplev/config/acx.m4, somewhat like calls
- in toplev/configure.ac but without the NCN_STRICT_CHECK_TARGET_TOOLS
- step, for each X to find a value for $(<X>_FOR_TARGET). N.B.: in-tree
- tools still override any ${target}-${tool} found in $PATH, i.e. only
- previously broken builds are affected.
-
- The variables $(<X>_FOR_TARGET) are usually overridden by the toplevel
- Makefile to the same value or better, but has to be set here too, as
- automake "wants" Makefiles to be self-contained (you get an error
- pointing out that the variable may be empty). If it hadn't been for
- that, SIM_AC_CHECK_TOOLCHAIN_FOR_PRIMARY_TARGET would not be needed.
- This detail should only (positively) affect users invoking "make
- check" in sim/ instead of "make check-sim" (or "make check") at the
- toplevel. Now the output from "configure" matches the target tools
- actually used by sim at test-time, for the "primary target".
-
- Using $(CC) for "example-" targets CC_FOR_TARGET is not changed, as
- that appears to be a deliberate special-case.
-
- Note that all tools still have to be installed and present in

- sim/testsuite: Support "requires: simoption <--name-of-option>"

-
- The immediate need was to check for presence of a simulator

- predicate I thought I'd handle the general (parametrized)
- need, so here's a generic predicate machinery and a (first)
- predicate to use together with it; checking whether a

- Commit a39487c6685f "sim: cris: use -sim with C tests for cris-elf

- cris*-*-elf, where testing had until then relied on
- "RUNTESTFLAGS=--target_board=cris-sim" being passed when running "make
- check-sim", adding the right options. While "-sim" happens to work,
- the baseboard-file cris-sim.exp uses "-sim3" so for consistency use
- that instead.
-
- Then commit b42f20d2ac72 "sim: testsuite: drop most specific istarget
- checks" caused " -sim" to be appended for *all* targets, which just
- doesn't work. For example, for crisv32-linux-gnu, that's not a
- recognized option and will cause a dejagnu error and further testing
- in c.exp will be aborted.
-
- While cris-sim.exp appends "-static" for *-linux-gnu, further changes
- in the test-suite have caused "linux"-specific tests to break, so that
- part will be tended to separately.

- sim cris: Correct PRIu32 to PRIx32
- In 5ee0bc23a68f "sim: clean up bfd_vma printing" there was
- an additional introduction of PRIx32 and PRIu32 but just in
- sim/cris/sim-if.c. One type of bug was fixed in commit
- d16ce6e4d581 "sim: cris: fix memory setup typos" but one
- remained; the PRIu32 usage is wrong, as hex output is
- desired; note the 0x prefix.
-
- Without this fix, you'll see output like:
- memory map 0:0x4000..0x5fff (8192 bytes) overlaps 0:0x0..0x16383 (91012 bytes)
- program stopped with signal 6 (Aborted).
- for some C programs, like some of the ones in the sim/cris/c
- testsuite from where the example is taken (freopen2.c).
-
- The bug behavior was with memory allocation. With an
- attempt to allocate memory using the brk syscall such that
- the room up to the next 8192-byte "page boundary" wasn't
- sufficient, the simulator memory allocation machinery horked
- on a consistency error when trying to allocate a memory
- block to raise the "end of the data segment": there was
- already memory allocated at that address.

- gdb/python: move styling support to gdb.styling
- This commit moves the two Python functions that are used for styling
- into a new module, gdb.styling, there's then a small update in
- python.c so GDB can find the functions in their new location.
-
- The motivation for this change is purely to try and reduce the clutter
- in the top-level gdb module, and encapsulate related functions into
- modules. I did ponder documenting these functions as part of the
- Python API, however, doing so would effectively "fix" the API, and I'm
- still wondering if there's improvements that could be made, also, the
- colorize function is only called in some cases now that GDB prefers
- libsource-highlight, so it's not entirely sure how this would work as
- part of a user facing API.
-
- Still, despite these functions never having been part of a documented
- API, it is possible that a user out there has overridden these to, in
- some way, customize how GDB performs styling. Moving the function as
- I propose in this patch could break things for that user, however,
- fixing this breakage is trivial, and, as these functions were never
- documented, I don't think we should be obliged to not break user code
- that relies on them.

- gdb: use python to colorize disassembler output
- This commit adds styling support to the disassembler output, as such
- two new commands are added to GDB:
-
- set style disassembler enabled on|off
- show style disassembler enabled
-
- In this commit I make use of the Python Pygments package to provide
- the styling. I did investigate making use of libsource-highlight,
- however, I found the highlighting results to be inferior to those of
- Pygments; only some mnemonics were highlighted, and highlighting of
- register names such as r9d and r8d (on x86-64) was incorrect.
-
- To enable disassembler highlighting via Pygments, I've added a new
- extension language hook, which is then implemented for Python. This
- hook is very similar to the existing hook for source code
- colorization.
-
- One possibly odd choice I made with the new hook is to pass a
- gdb.Architecture through, even though this is currently unused. The
- reason this argument is not used is that, currently, styling is
- performed identically for all architectures.
-
- However, even though the Python function used to perform styling of
- disassembly output is not part of any documented API, I don't want
- to close the door on a user overriding this function to provide
- architecture specific styling. To do this, the user would inevitably
- require access to the gdb.Architecture, and so I decided to add this
- field now.
-
- The styling is applied within gdb_disassembler::print_insn, to achieve
- this, gdb_disassembler now writes its output into a temporary buffer,
- styling is then applied to the contents of this buffer. Finally the
- gdb_disassembler buffer is copied out to its final destination stream.
-
- There's a new test to check that the disassembler output includes some
- escape sequences, though I don't check for specific colours; the
- precise colors will depend on which instructions are in the
- disassembler output, and, I guess, how pygments is configured.
-
- The only negative change with this commit is how we currently style
- addresses in GDB.
-
- Currently, when the disassembler wants to print an address, we call
- back into GDB, and GDB prints the address value using the `address`
- styling, and the symbol name using `function` styling. After this
- commit, if pygments is used, then all disassembler styling is done
- through pygments, and this include the address and symbol name parts
- of the disassembler output.
-
- I don't know how much of an issue this will be for people. There's
- already some precedent for this in GDB when we look at source styling.
- For example, function names in styled source listings are not styled
- using the `function` style, but instead, either GNU Source Highlight,
- or pygments gets to decide how the function name should be styled.
-
- If the Python pygments library is not present then GDB will continue
- to behave as it always has, the disassembler output is mostly
- unstyled, but the address and symbols are styled using the `address`
- and `function` styles, as they are today.
-
- However, if the user does `set style disassembler enabled off`, then
- all disassembler styling is switched off. This obviously covers the
- use of pygments, but also includes the minimal styling done by GDB
- when pygments is not available.

- PR28824, relro security issues
- Background
- ==========
- There are constraints on layout of binaries to meet demand paging and
- memory protection requirements. Demand paged binaries must have file
- offset mod pagesize equal to vma mod pagesize. Memory protection
- (executable, read, write status) can only change at page boundaries.
- The linker's MAXPAGESIZE variable gives the page size for these layout
- constraints.
-
- In a typical basic executable with two memory segments, text (RE) and
- data (RW), the data segment must start on a different page to the
- last text segment page. For example, with 64k pages and a small
- executable of 48k text and 1k data, the text segment might start at
- address 0x10000 and data at 0x20000 for a total of two 64k memory
- pages. Demand paging would require the image on disk to be 64k+1k
- in size. We can do better than that. If the data segment instead
- starts at 0x2c000 (the end of the text segment plus one 64k page) then
- there are still only two memory pages, but the disk image is now
- smaller, 48k+1k in size. This is why the linker normally starts the
- data segment at the end of the text segment plus one page. That
- simple heuristic isn't ideal in all cases. Changing our simple
- example to one with 64k-1 text size, following that heuristic would
- result in data starting at 0x2ffff. Now we have two 64k memory data
- pages for a data segment of 1k! If the data segment instead started
- at 0x30000 we'd get a single data segment page at the cost of 1 byte
- extra in the disk image, which is likely a good trade-off. So the
- linker does adjust the simple heuristic. Just how much disk image
- size increase is allowed is controlled by the linker's COMMONPAGESIZE
- variable.
-
- A PT_GNU_RELRO segment overlays the initial part of the data segment,
- saying that those pages should be made read-only after relocation by
- the dynamic loader. Page granularity for memory protection means that
- the end of the relro segment must be at a page boundary.
-
- The problem
- ===========
- Unfortunately most targets currently only align the end of the relro
- segment to COMMONPAGESIZE. That results in only partial relro
- protection if an executable is running with MAXPAGESIZE pages, since
- any part of the relro segment past the last MAXPAGESIZE boundary can't
- be made read-only without also affecting sections past the end of the
- relro segment. I believe this problem arose because x86 always runs
- with 4k (COMMPAGESIZE) memory pages, and therefore using a larger
- MAXPAGESIZE on x86 is for reasons other than the demand paging and
- memory page protection boundary requirements.
-
- The solution
- ============
- Always end the relro segment on a MAXPAGESIZE boundary, except for
- x86. Note that the relro segment, comprising of sections at the start
- of the data segment, is sized according to how those sections are laid
- out. That means the start of the relro segment is fixed relative to
- its end. Which also means the start of the data segment must be at a
- fixed address mod MAXPAGESIZE. So for relro the linker can't play
- games with the start of the data segment to save disk space. At
- least, not without introducing gaps between the relro sections. In
- fact, because the linker was starting layout using its simple
- heuristic of starting the data segment at the end of the text segment
- plus one page, it was sometimes introducing page gaps for no reason.
- See pr28743.

- x86: Disallow invalid relocation against protected symbol
- I am checking this into master and will backport it to 2.38 branch.
-
- H.J
- ----
- On x86, GCC 12 supports -mno-direct-extern-access to enable canonical
- reference to protected function and disable copy relocation. With
- -mno-direct-extern-access, the canonical protected function symbols must
- be accessed via canonical reference and the protected data symbols in
- shared libraries are non-copyable. Under glibc 2.35, non-canonical
- reference to the canonical protected function will get the run-time error:
-
- ./y: internal_f: ./libfoo.so: non-canonical reference to canonical protected function
-
- and copy relocations against the non-copyable protected symbols will get
- the run-time error:
-
- ./x: internal_i: ./libfoo.so: copy relocation against non-copyable protected symbol
-
- Update x86 linker to disallow non-canonical reference to the canonical
- protected function:
-
- ld: plt.o: non-canonical reference to canonical protected function `internal_f' in libfoo.so
- ld: failed to set dynamic section sizes: bad value
-
- and copy relocation against the non-copyable protected symbol:
-
- ld: main.o: copy relocation against non-copyable protected symbol `internal_i' in libfoo.so

- gdb: fix until behavior with trailing !is_stmt lines
- When using the command "until", it is expected that GDB will exit a
- loop if the current instruction is the last one related to that loop.
- However, if there were trailing non-statement instructions, "until"
- would just behave as "next". This was noticeable in clang-compiled
- code, but might happen with gcc-compiled as well. PR gdb/17315 relates
- to this problem, as running gdb.base/watchpoint.exp with clang
- would fail for this reason.
-
- To better understand this issue, consider the following source code,
- with line numbers marked on the left:
-
- 10: for (i = 0; i < 10; ++i)
- 11: loop_body ();
- 12: other_stuff ();
-
- If we transform this to pseudo-assembler, and generate a line table,
- we could end up with something like this:
-
- Address | Pseudo-Assembler | Line | Is-Statement?
-
- 0x100 | i = 0 | 10 | Yes
- 0x104 | loop_body () | 11 | Yes
- 0x108 | i = i + 1 | 10 | Yes
- 0x10c | if (i < 10): | 10 | No
- 0x110 | goto 0x104 | 10 | No
- 0x114 | other_stuff () | 12 | Yes
-
- Notice the two non-statement instructions at the end of the loop.
-
- The problem is that when we reach address 0x108 and use 'until',
- hoping to leave the loop, GDB sets up a stepping range that runs from
- the start of the function (0x100 in our example) to the end of the
- current line table entry, that is 0x10c in our example. GDB then
- starts stepping forward.
-
- When 0x10c is reached GDB spots that we have left the stepping range,
- that the new location is not a statement, and that the new location is
- associated with the same source line number as the previous stepping
- range. GDB then sets up a new stepping range that runs from 0x10c to
- 0x114, and continues stepping forward.
-
- Within that stepping range the inferior hits the goto (at 0x110) and
- loops back to address 0x104.
-
- At 0x104 GDB spots that we have left the previous stepping range, that
- the new address is marked as a statement, and that the new address is
- for a different source line. As a result, GDB stops and returns
- control to the user. This is not what the user was expecting, they
- expected GDB to exit the loop.
-
- The fix proposed in this patch, is that, when the user issues the
- 'until' command, and GDB sets up the initial stepping range, GDB will
- check subsequent SALs (symtab_and_lines) to see if they are
- non-statements associated with the same line number. If they are then
- the end of the initial stepping range is extended to the end of the
- non-statement SALs.
-
- In our example above, the user is at 0x108 and uses 'until', GDB now
- sets up a stepping range from the start of the function 0x100 to
- 0x114, the first address associated with a different line.
-
- Now as GDB steps around the loop it never leaves the initial stepping
- range. It is only when GDB exits the loop that we leave the stepping
- range, and the stepping finishes at address 0x114.
-
- This patch also adds a test case that can be run with gcc to test that
- this functionality is not broken in the future.

- This commit updates the output of 'maint info jit' to print not just
- the jit_code_entry address, but also the symfile address, and the
- symfile size.
-
- The new information could be obtained by looking into target memory at
- the contents of the jit_code_entry, but, by storing this information
- within gdb at the time the jit object is loaded, it is now possible to
- check if the jit_code_entry has been modified in target memory behind
- gdb's back.
-
- Additionally, the symfile address is the same address that is now used
- in the objfile names after commit 4a620b7e.
-

- gdb/linux: remove ptrace support check for exec, fork, vfork, vforkdone, clone, sysgood
- I think it's safe to remove checking support for these ptrace features,
- they have all been added in what is now ancient times (around the
- beginning of Linux 2.6). This allows removing a bit of complexity in
- linux-nat.c and nat/linux-ptrace.c.
-
- It also allows saving one extra fork every time we start debugging on
- Linux: linux_check_ptrace_features forks a child process to test if some
- ptrace features are supported. That child process forks a grand-child,
- to test whether ptrace reports an event for the fork by the child. This

- gdb/python: allow Value.format_string to return styled output
- Add a new argument to the gdb.Value.format_string method, 'styling'.
- This argument is False by default.
-
- When this argument is True, then the returned string can contain output
- styling escape sequences.
-
- When this argument is False, then the returned string will not contain
- any styling escape sequences.
-
- If the returned string is going to be printed to the user, then it is
- often nice to retain the GDB styling.
-
- For the testing, we need to adjust the TERM environment variable, as
- we do for all the styling tests. I'm now running all of the C tests
- in gdb.python/py-format-string.exp in an environment where styling
- could be generated, but only my new test should actually produce
- styled output, hopefully this will catch the case where a bug might
- cause format_string to always produce styled output.

- gdb: make thread_info::m_thread_fsm a std::unique_ptr
- While working on function calls, I realized that the thread_fsm member
- of struct thread_info is a raw pointer to a resource it owns. This
- commit changes the type of the thread_fsm member to a std::unique_ptr in
- order to signify this ownership relationship and slightly ease resource
- management (no need to manually call delete).
-
- To ensure consistent use, the field is made a private member
- (m_thread_fsm). The setter method (set_thread_fsm) can then check
- that it is incorrect to associate a FSM to a thread_info object if
- another one is already in place. This is ensured by an assertion.
-
- The function run_inferior_call takes an argument as a pointer to a
- call_thread_fsm and installs it in it in a thread_info instance. Also
- change this function's signature to accept a unique_ptr in order to
- signify that the ownership of the call_thread_fsm is transferred during
- the call.
-
- No user visible change expected after this commit.
-
- Tested on x86_64-linux with no regression observed.

- gdb: unbuffer all input streams when not using readline
- This commit should fix PR gdb/28711. What's actually going on is
- pretty involved, and there's still a bit of the story that I don't
- understand completely, however, from my observed results, I think that
- the change I propose making here (or something very similar) is going
- to be needed.
-
- The original bug report involves using eclipse to drive gdb using mi
- commands. A separate tty is spun off in which to send gdb the mi
- commands, this tty is created using the new-ui command.
-
- The behaviour observed is that, given a particular set of mi commands
- being sent to gdb, we sometimes see an ESPIPE error from a lseek
- call, which ultimately results in gdb terminating.
-
- The problems all originate from gdb_readline_no_editing_callback in
- gdb/event-top.c, where we can (sometimes) perform calls to fgetc, and
- allow glibc to perform buffering on the FILE object being used.
-
- I say sometime, because, gdb_readline_no_editing_callback already
- includes a call to disable the glibc buffering, but this is only done
- if the input stream is not a tty. In our case the input stream is a
- tty, so the buffering is left in place.
-
- The first step to understanding why this problem occurs is to
- understand that eclipse sends multiple commands to gdb very quickly
- without waiting for and answer to each command, eclipse plans to
- collect all of the command results after sending all the commands to
- gdb. In fact, eclipse sends the commands to gdb that they appear to
- arrive in the gdb process as a single block of data. When reproducing
- this issue within the testsuite I find it necessary to send multiple
- commands using a single write call.
-
- The next bit of the story gets a little involved, and this is where my
- understanding is not complete. I can describe the behaviour that I
- observe, and (for me at least) I'm happy that what I'm seeing, if a
- little strange, is consistent. In order to fully understand what's
- going on I think I would likely need to dive into kernel code, which
- currently seems unnecessary given that I'm happy with the solution I'm
- proposing.
-
- The following description all relates to input from a tty in which I'm
- not using readline. I see the same problems either when using a
- new-ui tty, or with gdb's standard, non-readline, mi tty.
-
- Here's what I observe happening when I send multiple commands to gdb
- using a single write, if I send gdb this:
-
- command_1\ncommand_2\ncommand_3
-
- then gdb's event loop will wake up (from its select) as it sees there
- is input available. We call into gdb_readline_no_editing_callback,
- where we call fgetc, glibc will do a single big read, and get back
- just:
-
- command_1\n
-
- that is, despite there being multiple lines of input available, I
- consistently get just a single line. From glibc a single character is
- returned from the fgetc call, and within gdb we accumulate characters,
- one at a time, into our own buffer. Eventually gdb sees the '\n'
- character, and dispatches the whole 'command_1' into gdb's command
- handler, which processes the command and prints the result. We then
- return to gdb_readline_no_editing_callback, which in turn returns to
- gdb's event loop where we re-enter the select.
-
- Inside the select we immediately see that there is more input waiting
- on the input stream, drop out of the select, and call back into
- gdb_readline_no_editing_callback. In this function we again call
- fgetc where glibc performs another big read. This time glibc gets:
-
- command_2\n
-
- that is, we once again get just a single line, despite there being a
- third line available. Just like the first command we copy the whole
- string, character by character into gdb's buffer, then handle the
- command. After handling the command we go to the event loop, enter,
- and then exit the select, and call back to the function
- gdb_readline_no_editing_callback.
-
- In gdb_readline_no_editing_callback we again call fgetc, this time
- glibc gets the string:
-
- command_3\n
-
- like before, we copy this to gdb's buffer and handle the command, then
- we return to the event loop. At this point the select blocks while we
- wait for more input to arrive.
-
- The important bit of this is that someone, somewhere is, it appears,
- taking care to split the incoming write into lines.
-
- My next experiment is to try something like:
-
- this_is_a_very_long_command\nshort_command\n
-
- However, I actually make 'this_is_a_very_long_command' very long, as
- in many hundreds of characters long. One way to do this is:
-
- echo xxxxxx.....xxxxx
-
- and just adding more and more 'x' characters as needed. What I'm
- aiming for is to have the first command be longer than glibc's
- internal read buffer, which, on my machine, is 1024 characters.
-
- However, for this discussion, lets imagine that glibc's buffer is just
- 8 characters (we can create just this situation by adding a suitable
- setbuf call into gdb_readline_no_editing_callback).
-
- Now, if I send gdb this data:
-
- abcdefghij\nkl\n
-
- The first read from glibc will get 'abcdefgh', that is a full 8
- character buffer. Once gdb has copied these to its buffer we call
- fgetc again, and now glibc will get 'ij\n', that is, just like before,
- multiple lines are split at the '\n' character. The full command,
- which is now in gdb's buffer can be handled 'abcdefghij', after which
- we go (via the event loop) back to gdb_readline_no_editing_callback.
- Now we call fgetc, and glibc will get 'kl\n', which is then handled in
- the normal way.
-
- So far, so good. However, there is, apparently, one edge case where
- the above rules don't apply.
-
- If the '\n' character is the first character read from the kernel,
- then the incoming lines are not split up. So, given glibc's 8
- character buffer, if I send gdb this:
-
- abcdefgh\nkl\n
-
- that is the first command is 8 characters plus a newline, then, on the
- first read (from within glibc) we get 'abcdefgh' in a single buffer.
- As there's no newline gdb calls fgetc again, and glibc does another
- large read, now we get:
-
- \nkl\n
-
- which doesn't follow the above pattern - the lines are not split into
- separate buffers!
-
- So, gdb reads the first character from glibc using fgetc, this is the
- newline. Now gdb has a complete command, and so the command is
- handled. We then return to the event loop and enter the select.
-
- The problem is that, as far as the kernel is concerned, there is no
- more input pending, it's all been read into glibc's buffer, and so the
- select doesn't return. The second command is basically stuck in
- glibc's buffer.
-
- If I send another command to gdb, or even just send an empty
- command (a lone newline) then the select returns, we call into
- gdb_readline_no_editing_callback, and now gdb sees the second
- command.
-
- OK, so the above is interesting, but it doesn't explain the ESPIPE
- error.
-
- Well, that's a slightly different, but related issue. The ESPIPE
- case will _only_ show up when using new-ui to create the separate tty
- for mi commands, and is a consequence of this commit:
-
- commit afe09f0b6311a4dd1a7e2dc6491550bb228734f8
- Date: Thu Jul 18 17:20:04 2019 +0100
-
- Fix for using named pipes on Windows
-
- Prior to this commit, the new-ui command would open the tty three
- times, once each for stdin, stderr, and stdout. After this commit we
- open the tty just once and reuse the FILE object for all three roles.
-
- Consider the problem case, where glibc has (unexpectedly) read the
- second command into its internal buffer. When we handle the first
- command we usually end up having to write something to the mi output
- stream.
-
- After the above commit the same FILE object represents both the input
- and output streams, so, when gdb tries to write to the FILE object,
- glibc spots that there is input pending within the input buffer, and
- so assumes that we have read ahead of where we should be in the input
- file. To correct for this glibc tries to do an lseek call to
- reposition the file offset of the output stream prior to writing to
- it. However, as the output stream is a tty, and seeking is not
- supported on a tty, this lseek call fails, this results in the ESPIPE,
- which ultimately causes gdb to terminate.
-
- So, now we understand why the ESPIPE triggers (which was what caused
- the gdb crash in the original bug report), and we also understand that
- sometime gdb will not handle the second command in a timely
- fashion (if the first command is just the wrong length). So, what to
- do about all this?
-
- We could revert the commit mentioned above (and implement its
- functionality another way). This would certainly resolve the ESPIPE
- issue, the buffered input would now only be on the input stream, the
- output stream would have no buffered input, and so glibc would never
- try to lseek, and so we'd never get the ESPIPE error.
-
- However, this only solves one of the two problems. We would still
- suffer from the problem where, if the first command is just the wrong
- length, the second command will not (immediately) get handled.
-
- The only solution I can see to this problem is to unbuffer the input
- stream. If glibc is not buffering the input, but instead, we read
- incoming data character by character from the kernel, then everything
- will be fine. As soon as we see the newline at the end of the first
- command we will handle the first command. As glibc will have no
- buffered input it will not be tempted to lseek, so no ESPIPE error.
- When we go have to the event loop there will be more data pending in
- the kernel, so the select will immediately return, and the second
- command will be processed.
-
- I'm tempted to suggest that we should move the unbuffering of the
- input stream out of gdb_readline_no_editing_callback and do it
- somewhere earlier, more like when we create the input streams.
- However, I've not done that in this commit for a couple of reasons:
-
- 1. By keeping the unbuffering in gdb_readline_no_editing_callback
- I'm making the smallest possible change that fixes the bug. Moving
- the unbuffering somewhere better can be done as a refactor later, if
- that 's felt to be important,
-
- 2. I don't think making repeated calls to unbuffer the input will
- have that much performance impact. We only make the unbuffer call
- once per call to gdb_readline_no_editing_callback, and, if the input
- stream is already unbuffered we'll return pretty quickly, so I don't
- see this as being massively costly,
-
- 3. Tom is currently doing lots of gdb stream management changes and
- I want to minimise the chances we'll conflict.
-
- So, this commit just changes gdb_readline_no_editing_callback to
- always unbuffer the input stream.
-
- The test for this issue sends two commands in a loop, with the first
- command growing bigger each time around the loop. I actually make the
- first command bigger by just adding whitespace to the front, as gdb
- still has to read the complete command (including whitespace) via
- glibc, so this is enough to trigger the bug.
-
- The original bug was reported when using a virtual machine, and in
- this situation we see this in the strace output:
-
- read(9, "70-var-info-path-expression var1.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa", 1024) = 64
- read(9, "\n71-var-info-path-expression var1.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa\n", 1024) = 67
-
- I'm not completely sure what's going on here, but it appears that the
- kernel on the virtual machine is delivering the input to glibc slower
- than I see on my real hardware; glibc asks for 1024 bytes, but only
- gets 64 bytes the first time. In the second read we see the problem
- case, the first character is the newline, but then the entire second
- command is included.
-
- If I run this exact example on my real hardware then the first command
- would not be truncated at 64 bytes, instead, I'd expect to see the
- newline included in the first read, with the second command split into
- a second read.
-
- So, for testing, I check cases where the first command is just a few
- characters (starting at 8 character), all the way up to 2048
- characters. Hopefully, this should mean we hit the problem case for
- most machine setups.
-
- The only last question relates to commit afe09f0b6311a4d that I
- mentioned earlier. That commit was intended to provide support for
- Microsoft named pipes:
-
- https://docs.microsoft.com/en-us/windows/win32/ipc/named-pipes
-
- I know next to nothing about this topic beyond a brief scan of the
- above link, but I think these windows named pipe are closer in
- behaviour to unix sockets than to unix named fifos.
-
- I am a little nervous that, after the above commit, we now use the
- same FILE for in, err, and out streams. In contrast, in a vanilla C
- program, I would expect different FILE objects for each stream.
-
- Still, I'm reluctant to revert the above commit (and provide the same
- functionality a different way) without a specific bug to point at,
- and, now that the streams are unbuffered, I expect a lot of the read
- and write calls are going straight to the kernel with minimal glibc
- involvement, so maybe it doesn't really matter. Anyway, I haven't
- touched the above patch, but it is something to keep in mind when
- working in this area.

- gdb/disasm: combine the no printing disassembler setup code
- We have three places in gdb where we initialise a disassembler that
- will not print anything (used for figuring out the length of

-
- Each of these places has its own stub function to act as a print like
- callback, the stub function is identical in each case, and just does
- nothing.
-
- In this commit I create a new function to initialise a disassembler
- that doesn't print anything, and have all three locations use this new

- gdb: add the 'set/show suppress-cli-notifications' command
- GDB already has a flag to suppress printing notification events, such
- as thread and inferior context switches, on the CLI. This is used
- internally when executing commands. Make the flag available to the
- user via a new command. This is expected to be useful in scripts.
-
- For instance, suppose that when Inferior 1 gets to a certain state,
- you want to add and set up a new inferior using the commands below,
- but you also want to have a reduced/clean output.
-
- define do-setup
- printf "Setting up Inferior 2...\n"
- add-inferior -exec a.out
- inferior 2
- break file.c:3
- run
- inferior 1
- printf "Done\n"
- end
-
- Currently, GDB prints
-
- (gdb) do-setup
- Setting up Inferior 2...
- [New inferior 2]
- Added inferior 2 on connection 1 (native)
- [Switching to inferior 2 [<null>] (/tmp/a.out)]
- Breakpoint 2 at 0x1155: file file.c, line 3.
-
- Thread 2.1 "a.out" hit Breakpoint 2, main () at file.c:3
- 3 return 0;
- [Switching to inferior 1 [process 7670] (/tmp/test)]
- [Switching to thread 1.1 (process 7670)]
- #0 main () at test.c:2
- 2 int a = 1;
- Done
-
- GDB's Python API make it possible to capture and return GDB's output,
- but this does not work for all the streams. In particular, CLI
- notification events are not captured:
-
- (gdb) python gdb.execute("do-setup", False, True)
- [Switching to inferior 2 [<null>] (/tmp/a.out)]
-
- Thread 2.1 "a.out" hit Breakpoint 2, main () at file.c:3
- 3 return 0;
- [Switching to inferior 1 [process 8263] (/tmp/test)]
- [Switching to thread 1.1 (process 8263)]
- #0 main () at test.c:2
- 2 int a = 1;
-
- You can use the new "set suppress-cli-notifications" command to
- suppress the output:
-
- (gdb) set suppress-cli-notifications on
- (gdb) do-setup
- Setting up Inferior 2...
- [New inferior 2]
- Added inferior 2 on connection 1 (native)
- Breakpoint 2 at 0x1155: file file.c, line 3.
- Done

- Allow non-ASCII characters in Rust identifiers
- Rust 1.53 (quite a while ago now) ungated the support for non-ASCII
- identifiers. This didn't work in gdb. This is PR rust/20166.
-
- This patch fixes the problem by allowing non-ASCII characters to be
- considered as identifier components. It seemed simplest to just pass
- them through -- doing any extra checking didn't seem worthwhile.
-
- The new test also verifies that such characters are allowed in strings
- and character literals as well. The latter also required a bit of
- work in the lexer.

- Fix Rust parser bug with function fields
- In Rust, 'obj.f()' is a method call -- but '(obj.f)()' is a call of a
- function-valued field 'f' in 'obj'. The Rust parser in gdb currently
- gets this wrong. This is PR rust/24082.
-
- The expression and Rust parser rewrites made this simple to fix --
- simply wrapping a parenthesized expression in a new operation handles
- it. This patch has a slight hack because I didn't want to introduce a
- new exp_opcode enumeration constant just for this. IMO this doesn't
- matter, since we should work toward removing dependencies on these
- opcodes anyway; but let me know what you think of this.

-
- gdb/doc: update docs for 'info win' and 'winheight' commands
- This started by noticing that the docs for 'winheight' are out of
- date, the docs currently give a specific list of possible window
- names. However, now that windows can be implemented in Python, it is
- not possible to list all possible names.
-
- I now link the user to a mechanism by which they can discover the
- valid names for themselves at run time (by using 'info win'). That,
- and the fact that gdb provides tab-completion of the name at the
- command line, feels good enough.
-
- Finally, I noticed that the docs for 'win info' don't explicitly say
- that the name of the window is given in the output. This could
- probably have been inferred, but given I'm now linking to this as a
- mechanism to find the window name, I'd prefer to mention that the name
- can be found in the output.
-
-2022-02-06 Andrew Burgess <aburgess@redhat.com>
-
- gdb/tui: add window width information to 'info win' output
- Now that we support horizontal window placement in the tui, it makes
- sense to have 'info win' include the width, as well as the height, of
- the currently visible windows.
-
- That's what this commit does. Example output is now:
-
- (gdb) info win
- Name Lines Columns Focus
- src 12 40 (has focus)
- asm 12 41
- status 1 80
- cmd 11 80
-
- I've added a NEWS entry, but the documentation was already suitably
- vague, it just says that 'info win' displays the size of the visible
- windows, so I don't think anything needs to be added there.
-
- I've also added some tests, as far as I could find, the 'info win'
- command was previously untested.

- sim: Allow toggling of quiet NaN-bit semantics
- IEEE754-1985 specifies the top bit of the mantissa as an indicator
- of signalling vs. quiet NaN, but does not define the precise semantics.
- Most architectures treat this bit as indicating quiet NaN, but legacy
- (pre-R6) MIPS goes the other way and treats it as signalling NaN.
-
- This used to be controlled by a macro that was only defined for MIPS.
- This patch replaces the macro with a variable to track the current
- semantics of the NaN bit and allows differentiation between older
- (pre-R6) and and newer MIPS cores.

- Remove arm-aout and arm-coff support
-
- This also removes arm-netbsd (not arm-netbsdelf!), arm-openbsd, and
- arm-riscix. Those targets weren't on the obsolete list but they are
- all aout, and it doesn't make all that much sense to remove arm-aout
- without removing them too.

- gdb: include jit_code_entry::symfile_addr value in names of objfiles created by jit reader API
- This commit includes the JIT object's symfile address in the names of
- objfiles created by JIT reader API (e.g., << JIT compiled code at
- 0x7ffd8a0c77a0 >>). This allows one to at least differentiate one from
- another.
-
- The address is the one that the debugged program has put in
- jit_code_entry::symfile_addr, and that the JIT reader's read function
- receives. As we can see in gdb.base/jit-reader-host.c and
- gdb.base/jit-reader.c, that may not be the actual value of where the
- JIT-ed code is. But it is a value chosen by the author of the JIT
- engine and the JIT reader, so including this value in the objfile name
- may help them correlate the JIT objfiles created by with their logs /
- data structures.
-
- To access this field, we need to pass down a reference to the
- jit_code_entry. So make jit_dbg_reader_data a structure (instead of an
- alias for a CORE_ADDR) that includes the address of the code entry in
- the inferior's address space (the previous meaning of
- jit_dbg_reader_data) plus a reference to the jit_code_entry as read into
- GDB's address space. And while at it, pass down the gdbarch, so that we
- don't have to call target_gdbarch.

- Improve Ada unchecked union type printing
- Currently, "ptype" of an Ada unchecked union may show a
- compiler-generated wrapper structure in its output. It's more
- Ada-like to elide this structure, which is what this patch implements.
- It turned out to be simplest to reuse a part of print_variant_clauses
- for this.
-
- As this is Ada-specific, and Joel already reviewed it internally, I am
- going to check it in.

-
- Remove host_hex_value
- I noticed that host_hex_value is redundant, because gdbsupport already
- has fromhex. This patch removes the former in favor of the latter.
-
- Regression tested on x86-64 Fedora 34.

-
- Support symbol+offset lookup in addr2line
- The Linux kernel usually ouputs symbol+offset instead of plain code
- addresses these days, to avoid leaking ASLR secrets and to handle
- dynamically loaded modules.
-
- Converting those with addr2line is somewhat involved: it requires
- looking up the symbol first using nm and then manually compute the
- offset, and then pass it to addr2line.
-
- This patch implements the necessary steps directly in addr2line,
- by looking up the symbol (with demangling if needed) and computing
- the offset.
-
- It's possible that a symbol is ambigious with a hex number. In this
- case it uses the symbol lookup if the string contains a +. When it isn't
- ambigious the + is optional.

- gdb: fix formatting for help set/show extended-prompt
- The formatting of the help text for 'help set extended-prompt' and
- 'help show extended-prompt' is a little off.
-
- Here's the offending snippet:
-
- Substitutions are applied to VALUE to compute the real prompt.
-
- The currently defined substitutions are:
- \[ Begins a sequence of non-printing characters.
- \\ A backslash.
- \] Ends a sequence of non-printing characters.
- \e The ESC character.
-
- Notice that the line for '\[' is indented more that the others.
-
- Turns out this is due to how we build this help text, something which
- is done in Python. We extended a classes __doc__ string with some
- dynamically generated text.
-
- The classes doc string looks like this:
-
- """Set the extended prompt.
-
- Usage: set extended-prompt VALUE
-
- Substitutions are applied to VALUE to compute the real prompt.
-
- The currently defined substitutions are:
- """
-
- Notice the closing """ are in a line of their own, and include some
- white space just before. It's this extra white space that's causing
- the problem.
-
- Fix the formatting issue by moving the """ to the end of the previous
- line. I then add the extra newline in at the point where the doc
- string is merged with the dynamically generated text.
-
- Now everything lines up correctly.

- gdb: test to check one aspect of the linespec parsing code
- While working on the fix for PR cli/28665 (see previous couple of
- commits), I was playing with making a change in the linespec parsing
- code. Specifically, I was thinking about whether the spec_string for
- LINESPEC_LOCATION locations should ever be nullptr.
-
- I made a change to prevent the spec_string from ever being nullptr,
- tested gdb, and saw no regressions.
-
- However, as part of this work I was reviewing how the breakpoint code
- handles this case (spec_string being nullptr), and spotted that in
- parse_breakpoint_sals the nullptr case is specifically handled, so
- changing this should have caused a regression. But I didn't see one.
-
- So, this commit adds a comment in location.c mentioning that the
- nullptr case is (a) not an oversight, and (b) is required. Then I add
- a new test to gdb.base/break.exp that ensures a change in this area
- will cause a regression.
-
- This test passes on current gdb, but with my modified (and broken)
- gdb, the test would fail.

- gdb: handle calls to edit command passing only a linespec condition
- While working on the previous commit to fix PR cli/28665, I noticed
- that the 'edit' command would suffer from the same problem. That is,
- something like:
-
- (gdb) edit task 123
-
- would cause GDB to break. For a full explanation of what's going on
- here, see the commit message for the previous commit.
-
- As with the previous commit, this issue can be prevented by detecting,
- and throwing, a junk at the end of the line error earlier, before
- calling decode_line_1.
-
- So, that's what this commit does. I've also added some tests for this
- issue.
-
- Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28665

-2022-02-02 Andrew Burgess <aburgess@redhat.com>
-
- gdb: handle calls to list command passing only a linespec condition
- In PR cli/28665, it was reported that GDB would crash when given a
- command like:
-
- (gdb) list task 123
-
- The problem here is that in cli/cli-cmd.c:list_command, the string
- 'task 123' is passed to string_to_event_location in find a location
- specification. However, this location parsing understands about
- breakpoint conditions, and so, will stop parsing when it sees
- something that looks like a condition, in this case, the 'task 123'
- looks like a breakpoint condition.
-
- As a result, the location we get back from string_to_event_location
- has no actual location specification attached to it. The actual call
- path is:
-
- list_command
- string_to_event_location
- string_to_event_location_basic
- new_linespec_location
-
- In new_linespec_location we call linespec_lex_to_end, which looks at
- 'task 123' and decides that there's nothing there that describes a
- location. As such, in new_linespec_location, the spec_string field of
- the location is left as nullptr.
-
- Back in list_command we then call decode_line_1, which calls
- event_location_to_sals, which calls parse_linespec, which takes the
- spec_string we found earlier, and tries to converts this into a list
- of sals.
-
- However, parse_linespec is not intended to be passed a nullptr, for
- example, calling is_ada_operator will try to access through the
- nullptr, causing undefined behaviour. But there are other cases
- within parse_linespec which don't expect to see a nullptr.
-
- When looking at how to fix this issue, I first considered having
- linespec_lex_to_end detect the problem. That function understands
- when the first thing in the linespec is a condition keyword, and so,
- could throw an error saying something like: "no linespec before
- condition keyword", however, this is not going to work, at least, not
- without additional changes to GDB, it is valid to place a breakpoint
- like:
-
- (gdb) break task 123
-
- This will place a breakpoint at the current location with the
- condition 'task 123', and changing linespec_lex_to_end breaks this
- behaviour.
-
- So, next, I considered what would happen if I added a condition to an
- otherwise valid list command, this is what I see:
-
- (gdb) list file.c:1 task 123
- Junk at end of line specification.
- (gdb)
-
- So, then I wondered, could we just pull the "Junk" detection forward,
- so that we throw the error earlier, before we call decode_line_1?
-
- It turns out that yes we can. Well, sort of.
-
- It is simpler, I think, to add a separate check into the list_command
- function, after calling string_to_event_location, but before calling
- decode_line_1. We know when we call string_to_event_location that the
- string in question is not empty, so, after calling
- string_to_event_location, if non of the string has been consumed, then
- the content of the string must be junk - it clearly doesn't look like
- a location specification.
-
- I've reused the same "Junk at end of line specification." error for
- consistency, and added a few tests to cover this issue.
-
- While the first version of this patch was on the mailing list, a
- second bug PR gdb/28797 was raised. This was for a very similar
- issue, but this time the problem command was:
-
- (gdb) list ,,
-
- Here the list command understands about the first comma, list can have
- two arguments separated by a comma, and the first argument can be
- missing. So we end up trying to parse the second command "," as a
- linespec.
-
- However, in linespec_lex_to_end, we will stop parsing a linespec at a
- comma, so, in the above case we end up with an empty linespec (between
- the two commas), and, like above, this results in the spec_string
- being nullptr.
-
- As with the previous case, I've resolved this issue by adding an extra
- check for junk at the end of the line - after parsing (or failing to
- parse) the nothing between the two commas, we still have the "," left
- at the end of the list command line - when we see this we can throw
- the same "junk at the end of the line" error, and all is good.
-
- I've added tests for this case too.

- gdb/testsuite: move linespec test into gdb.linespec/ directory
- The gdb.base/linespecs.exp test should really live in the gdb.linespec
- directory, so lets move it there.
-
- As we already have gdb.linespec/linespec.exp, I've renamed the test to
- gdb.linespec/errors.exp, as this better reflects what the test is
- actually checking.
-
- Finally, the test script doesn't have its own source file, it was
- reusing a random other source file, gdb.base/memattr.c. Now the tests
- script is in gdb.linespec/, I've updated the test to use a different
- source file from that directory.

- gdb: add empty string check in parse_linespec
- If parse_linespec (linespec.c) is passed ARG as an empty string then
- we end up calling `strchr (linespec_quote_characters, '\0')`, which
- will return a pointer to the '\0' at the end of
- linespec_quote_characters. This then results in GDB calling
- skip_quote_char with `ARG + 1`, which is undefined behaviour (as ARG
- only contained a single character, the '\0').
-
- Fix this by checking for the first character of ARG being '\0' before
- the call to strchr.
-
- I have additionally added an assertion that ARG can't itself be
- nullptr, as calling is_ada_operator with nullptr can end up calling
- 'startswith' on the nullptr, which is undefined behaviour.
-
- Finally, I moved the declaration of TOKEN into the body of
- parse_linespec, to where TOKEN is defined.
-
- This patch came about while I was working on fixes for PR cli/28665
- and PR gdb/28797. The actual fixes for these two issues will be in a
- later commit in this series, but, with this patch in place, both of
- the above bugs would hit the new assertion rather than accessing
- invalid memory and crashing. The '\0' check is not currently ever
- hit, but just makes the code a little safer.
-
- Because this patch only changes the nature of the failure for the
- above two bugs, there's no tests here. A later commit will fix the
- above two issues, at which point I'll add some tests.

- gdb: update the comment on string_to_event_location
- The comment on string_to_event_location is (I believe) out of date.
- This commit fixes the two issues I see:
-
- 1. This function can't return NULL any more. The implementation
- calls string_to_explicit_location which can return NULL, but if this
- is the case we then call string_to_event_location_basic, which I
- don't believe can ever return NULL.
-
- 2. I've removed the mention that the returned string is malloc'd,
- though this is true, now that we return a managed pointer, I believe
- the source of the memory allocation is irrelevant, and so, shouldn't
- be discussed in the header comment.
-
- There should be no user visible changes after this commit.

- gdb, testsuite, fortran: adapt info symbol expected output for intel compilers
- Info symbol is expected to print the symbol table name of a symbol, since
- symbol lookup happens via the minimal symbol table. This name
- corresponds to the linkage name in the full symbol table.
-
- For gfortran (and maybe others) these names currently have the form
- XXXX.NUMBER where XXXX is the symbol name and NUMBER a compiler
- generated appendix for mangling.
- An example taken from the modified nested-funcs-2.exp would be
-
- ~~~~
- $ objdump -t ./outputs/gdb.fortran/nested-funcs-2/nested-funcs-2 | grep \
- increment
- 00000000000014ab l F .text 0000000000000095 increment.3883
- 000000000000141c l F .text 000000000000008f increment_program_global.3881
- ~~~~
-
- This mangled name gets recognized by the Ada demangler/decoder and decoded as
- Ada to XXXX (setting the symbol language to Ada). This leads to output
- of XXXX over XXXX.NUMBER for info symbol on gfortran symbols.
-
- For ifort and ifx the generated linkage names have the form
- SCOPEA_SCOPEB_XXXX_ which are not recognized by the Ada decoder (or any
- other demangler for that matter) and thus printed as is.
- The respective objdump in the above case looks like
-
- ~~~~
- $ objdump -t ./outputs/gdb.fortran/nested-funcs-2/nested-funcs-2 | grep \
- increment
- 0000000000403a44 l F .text 0000000000000074 contains_keyword_IP_increment_
- 0000000000403ab8 l F .text 0000000000000070
- contains_keyword_IP_increment_program_global_
- ~~~~
-
- In the unmodified testcase this results in 'fails' when ran with the intel
- compilers:
-

- FreeBSD x86 nat: Use register maps for GP register sets.
- Rather than using the x86-specific register offset tables, use

- FreeBSD/amd64 will now report additional segment registers ($ds, $es,
- $fs, and $gs) for both 32-bit and 64-bit processes.
-
- As part of these changes, the FreeBSD x86 native targets no longer use
- amd64-bsd-nat.c or i386-bsd-nat.c. Remove FreeBSD-specific register
- handling (for $fs_base, $gs_base, and XSAVE state) from these files.
- Similarly, remove the global x86bsd_xsave_len from x86-bsd-nat.c. The
- FreeBSD x86 native targets use a static xsave_len instead.

- While here, rework the probing of PT_GETXMMREGS on FreeBSD/i386.
- Probe the ptrace op once in the target read_description method and
- cache the result for the future similar to the way the status of XSAVE
- support is probed in the read_description method. In addition, return
- the proper xcr0 mask (X87-only) for old kernels or systems without
- either XSAVE or XMM support.

- FreeBSD x86: Use tramp-frame for signal frames.
- Use a register map to describe the registers in mcontext_t as part of
- the signal frame as is done on several other FreeBSD arches. This
- permits fetching the fsbase and gsbase register values from the signal
- frame for both amd64 and i386 and permits fetching additional segment
- registers stored as 16-bit values on amd64.
-
- While signal frames on FreeBSD do contain floating point/XSAVE state,
- these unwinders do not attempt to supply those registers. The
- existing x86 signal frame uwinders do not support these registers, and
- the only existing functions which handle FSAVE/FXSAVE/XSAVE state all
- work with regcaches. In the future these unwinders could create a
- tempory regcache, collect floating point registers, and then supply
- values out of the regcache into the trad-frame.

-
- Use register maps for gp regsets on FreeBSD/x86 core dumps.
- In particular, this permits reporting the value of the $ds, $es, $fs,
- and $gs segment registers from amd64 core dumps since they are stored
- as 16-bit values rather than the 32-bit size assumed by i386_gregset.

-
- regcache: Zero-extend small registers described by a register map.
- When registers are supplied via regcache_supply_register from a
- register block described by a register map, registers may be stored in
- slots smaller than GDB's native register size (e.g. x86 segment
- registers are 16 bits, but the GDB registers for those are 32-bits).
- regcache_collect_regset is careful to zero-extend slots larger than a
- register size, but regcache_supply_regset just used
- regcache::raw_supply_part and did not initialize the upper bytes of a
- register value.
-
- trad_frame_set_reg_regmap assumes these semantics (zero-extending
- short registers). Upcoming patches also require these semantics for
- handling x86 segment register values stored in 16-bit slots on
- FreeBSD. Note that architecturally x86 segment registers are 16 bits,
- but the x86 gdb architectures treat these registers as 32 bits.

- FreeBSD x86: Remove fallback for detecting signal trampolines by address.
- A few FreeBSD releases did not include the page holding the signal
- code in core dumps. As a workaround, a sysctl was used to fetch the
- default location of the signal code instead. The youngest affected
- FreeBSD release is 10.1 released in November 2014 and EOLed in
- December 2016. The fallback only works for native processes and would
- require a separate unwinder once the FreeBSD arches are converted to
- use tramp_frame for signal frames.
-
- Remove support for pre-5.0 FreeBSD/i386 signal trampolines.
- The last relevant release (FreeBSD 4.11) was released in January of
- 2005.
-
- Remove vestigal FreeBSD/i386 3.x support.
- This was orphaned when a.out support was removed as the FreeBSD/i386
- ELF support always used the register layouts from 4.0+.

- When building with clang, I run into an error:
-

- elision [-Werror,-Wpessimizing-move]
- tal.addr_string = std::move (gdb_dis_out.release ());

- tal.addr_string = std::move (gdb_dis_out.release ());
- ^~~~~~~~~~~ ~

-
- The error above is caused by the recent commit 5d10a2041eb8 ("gdb: add
- string_file::release method").
-
- Fix this by removing std::move.

- Add top-level .editorconfig file
- Add a .editorconfig [1] file. This helps configure editors
- automatically with the right whitespace settings. It will help me,
- since I need to juggle with different whitespace settings for different
- projects. But I think it can also help newcomers get things right from
- the start.
-
- Some editors have native support for reading these files, while others
- require a plug-in [2]. And if you don't want to use it, then this file
- doesn't change anything to your life.
-
- I added rules for the kinds of files I edit most often, but more can be
- added later. I assumed that the rules were the same for GDB and the
- other projects, but if that's not the case, we can always put
- .editorconfig files in project subdirectories to override settings.

- PR28827, assertion building LLVM 9 on powerpc64le-linux-gnu
- The assertion is this one in ppc_build_one_stub
- BFD_ASSERT (stub_entry->stub_offset >= stub_entry->group->stub_sec->size);
- It is checking that a stub doesn't overwrite the tail of a previous
- stub, so not something trivial.
-
- Normally, stub sizing iterates until no stubs are added, detected by
- no change in stub section size. Iteration also continues if no stubs
- are added but one or more stubs increases in size, which also can be
- detected by a change in stub section size. But there is a
- pathological case where stub section sizing decreases one iteration
- then increases the next. To handle that situation, stub sizing also
- stops at more than STUB_SHRINK_ITER (20) iterations when calculated
- stub section size is smaller. The previous larger size is kept for
- the actual layout (so that building the stubs, which behaves like
- another iteration of stub sizing, will see the stub section sizes
- shrink). The problem with that stopping condition is that it assumes
- that stub sizing is only affected by addresses external to the stub
- sections, which isn't always true.
-
- This patch fixes that by also keeping larger individual stub_offset
- addresses past STUB_SHRINK_ITER. It also catches a further
- pathological case where one stub shrinks and another expands in such a
- way that no stub section size change is seen.

- Since there are some binaries with this in the wild, I think it would be
- useful for GDB to work around this. I did the obvious simple thing, if
- the DW_AT_data_member_location's value is -1, replace it with 0. I
- added a producer check to only apply this fixup for GCC 11. The idea is
- that if some other compiler ever uses a DW_AT_data_member_location value
- of -1 by mistake, we don't know (before analyzing the bug at least) if
- they did mean 0 or some other value. So I wouldn't want to apply the
- fixup in that case.

- Fix GDB internal error by using text (instead of data) section offset
- Fedora Rawhide is now using gcc-12.0. As part of updating to the
- gcc-12.0 package set, Rawhide is also now using a version of libgcc_s
- which lacks a .data section. This causes gdb to fail in the following
- fashion while debugging a program (such as gdb) which uses libgcc_s:
-
- (top-gdb) run
- Starting program: rawhide-master/bld/gdb/gdb
- ...
- objfiles.h:467: internal-error: sect_index_data not initialized
- A problem internal to GDB has been detected,
- further debugging may prove unreliable.
- ...
-
- I snipped the backtrace from the above output. Instead, here's a
- portion of a backtrace obtained using GDB's backtrace command.
- (Obviously, in order to obtain it, I used a GDB which has been patched
- with this commit.)

-
- The function 'relocate_address' in gdb/stap-probe.c attempts to do
- its "relocation" by using objfile->data_section_offset(). That
- method, data_section_offset() is defined as follows in objfiles.h:
-
- CORE_ADDR data_section_offset () const
- {
- return section_offsets[SECT_OFF_DATA (this)];
- }
-
- The internal error occurs when the SECT_OFF_DATA macro finds that the
- 'sect_index_data' field is -1:
-
- #define SECT_OFF_DATA(objfile) \
- ((objfile->sect_index_data == -1) \
- ? (internal_error (__FILE__, __LINE__, \
- _("sect_index_data not initialized")), -1) \
- : objfile->sect_index_data)
-
- relocate_address() is obtaining the section offset in order to compute
- a relocated address. For some ABIs, such as the System V ABI, the
- section offsets will all be the same. So for those ABIs, it doesn't
- matter which offset is used. However, other ABIs, such as the FDPIC
- ABI, will have different offsets for the various sections. Thus, for
- those ABIs, it is vital that this and other relocation code use the
- correct offset.
-
- In stap_probe::get_relocated_address, the address to which to add the
- offset (thus forming the relocated address) is obtained via
- this->get_address (); get_address is a getter for m_address in
- probe.h. It's documented/defined as follows (also in probe.h):
-
- /* The address where the probe is inserted, relative to
- SECT_OFF_TEXT. */
- CORE_ADDR m_address;
-
- (Thanks to Tom Tromey for this observation.)
-
- So, based on this, the current use of data_section_offset /
- SECT_OFF_DATA is wrong. This relocation code should have been using
- text_section_offset / SECT_OFF_TEXT all along. That being the
- case, I've adjusted the stap-probe.c relocation code accordingly.
-
- Searching the sources turned up one other use of data_section_offset,
- in gdb/dtrace-probe.c, so I've updated that code as well. The same
- reasoning presented above applies to this case too.
-
- Summary:
-
- * gdb/dtrace-probe.c (dtrace_probe::get_relocated_address):
- Use method text_section_offset instead of data_section_offset.
- * gdb/stap-probe.c (relocate_address): Likewise.

- gdb, btrace: switch threads in remote_btrace_maybe_reopen()
- In remote_btrace_maybe_reopen() we iterate over threads and use
- set_general_thread() to set the thread from which to transfer the btrace
- configuration.
-
- This sets the remote general thread but does not affect inferior_ptid. On
- the xfer request later on, remote_target::xfer_partial() again sets the
- remote general thread to inferior_ptid, overwriting what

-
- In one case, this led to inferior_ptid being null_ptid when we tried to
- enable tracing on a newly created thread inside a newly created process
- during attach.
-
- This, in turn, led to find_inferior_pid() asserting when we iterated over
- threads in record_btrace_is_replaying(), which was called from
- record_btrace_target::xfer_partial() when reading the btrace configuration
- of the new thread to check whether it was already being recorded.

- gdb/python: handle non utf-8 characters when source highlighting
- This commit adds support for source files that contain non utf-8
- characters when performing source styling using the Python pygments
- package. This does not change the behaviour of GDB when the GNU
- Source Highlight library is used.
-
- For the following problem description, assume that either GDB is built
- without GNU Source Highlight support, of that this has been disabled
- using 'maintenance set gnu-source-highlight enabled off'.
-
- The initial problem reported was that a source file containing non
- utf-8 characters would cause GDB to print a Python exception, and then
- display the source without styling, e.g.:
-
- Python Exception <class 'UnicodeDecodeError'>: 'utf-8' codec can't decode byte 0xc0 in position 142: invalid start byte
- /* Source code here, without styling... */
-
- Further, as the user steps through different source files, each time
- the problematic source file was evicted from the source cache, and
- then later reloaded, the exception would be printed again.
-
- Finally, this problem is only present when using Python 3, this issue
- is not present for Python 2.
-
- What makes this especially frustrating is that GDB can clearly print
- the source file contents, they're right there... If we disable
- styling completely, or make use of the GNU Source Highlight library,
- then everything is fine. So why is there an error when we try to
- apply styling using Python?
-
- The problem is the use of PyString_FromString (which is an alias for
- PyUnicode_FromString in Python 3), this function converts a C string
- into a either a Unicode object (Py3) or a str object (Py2). For
- Python 2 there is no unicode encoding performed during this function
- call, but for Python 3 the input is assumed to be a uft-8 encoding
- string for the purpose of the conversion. And here of course, is the
- problem, if the source file contains non utf-8 characters, then it
- should not be treated as utf-8, but that's what we do, and that's why
- we get an error.
-
- My first thought when looking at this was to spot when the
- PyString_FromString call failed with a UnicodeDecodeError and silently
- ignore the error. This would mean that GDB would print the source
- without styling, but would also avoid the annoying exception message.
-
- However, I also make use of `pygmentize`, a command line wrapper
- around the Python pygments module, which I use to apply syntax
- highlighting in the output of `less`. And this command line wrapper
- is quite happy to syntax highlight my source file that contains non
- utf-8 characters, so it feels like the problem should be solvable.
-
- It turns out that inside the pygments module there is already support
- for guessing the encoding of the incoming file content, if the
- incoming content is not already a Unicode string. This is what
- happens for Python 2 where the incoming content is of `str` type.
-
- We could try and make GDB smarter when it comes to converting C
- strings into Python Unicode objects; this would probably require us to
- just try a couple of different encoding schemes rather than just
- giving up after utf-8.
-
- However, I figure, why bother? The pygments module already does this
- for us, and the colorize API is not part of the documented external
- API of GDB. So, why not just change the colorize API, instead of the
- content being a Unicode string (for Python 3), lets just make the
- content be a bytes object. The pygments module can then take
- responsibility for guessing the encoding.
-
- So, currently, the colorize API receives a unicode object, and returns
- a unicode object. I propose that the colorize API receive a bytes
- object, and return a bytes object.

-2022-01-26 Tom Tromey <tom@tromey.com>
-
- Add ui_file::wrap_here
- Right now, wrap_here is a global function. In the long run, we'd like
- output streams to be relatively self-contained objects, and having a
- global function like this is counter to that goal. Also, existing
- code freely mixes writes to some parameterized stream with calls to
- wrap_here -- but wrap_here only really affects gdb_stdout, so this is
- also incoherent.
-
- This step is a patch toward making wrap_here more sane. It adds a
- wrap_here method to ui_file and changes ui_out implementations to use
- it.
-
-2022-01-26 Tom Tromey <tom@tromey.com>
-
- Convert wrap_here to use integer parameter
- I think it only really makes sense to call wrap_here with an argument
- consisting solely of spaces. Given this, it seemed better to me that
- the argument be an int, rather than a string. This patch is the
- result. Much of it was written by a script.

- gdb/python: improve the auto help text for gdb.Parameter
- This commit attempts to improve the help text that is generated for
- gdb.Parameter objects when the user fails to provide their own
- documentation.
-
- Documentation for a gdb.Parameter is currently pulled from two
- sources: the class documentation string, and the set_doc/show_doc
- class attributes. Thus, a fully documented parameter might look like
- this:
-
- class Param_All (gdb.Parameter):
- """This is the class documentation string."""
-
- show_doc = "Show the state of this parameter"
- set_doc = "Set the state of this parameter"
-
- def get_set_string (self):
- val = "on"
- if (self.value == False):
- val = "off"
- return "Test Parameter has been set to " + val
-
- def __init__ (self, name):
- super (Param_All, self).__init__ (name, gdb.COMMAND_DATA, gdb.PARAM_BOOLEAN)
- self._value = True
-
- Param_All ('param-all')
-
- Then in GDB we see this:
-
- (gdb) help set param-all
- Set the state of this parameter
- This is the class documentation string.
-
- Which is fine. But, if the user skips both of the documentation parts
- like this:
-
- class Param_None (gdb.Parameter):
-
- def get_set_string (self):
- val = "on"
- if (self.value == False):
- val = "off"
- return "Test Parameter has been set to " + val
-
- def __init__ (self, name):
- super (Param_None, self).__init__ (name, gdb.COMMAND_DATA, gdb.PARAM_BOOLEAN)
- self._value = True
-
- Param_None ('param-none')
-
- Now in GDB we see this:
-
- (gdb) help set param-none
- This command is not documented.
- This command is not documented.
-
- That's not great, the duplicated text looks a bit weird. If we drop
- different parts we get different results. Here's what we get if the
- user drops the set_doc and show_doc attributes:
-
- (gdb) help set param-doc
- This command is not documented.
- This is the class documentation string.
-
- That kind of sucks, we say it's undocumented, then proceed to print
- the documentation. Finally, if we drop the class documentation but
- keep the set_doc and show_doc:
-
- (gdb) help set param-set-show
- Set the state of this parameter
- This command is not documented.
-
- That seems OK.
-
- So, I think there's room for improvement.
-
- With this patch, for the four cases above we now see this:
-
- # All values provided by the user, no change in this case:
- (gdb) help set param-all
- Set the state of this parameter
- This is the class documentation string.
-
- # Nothing provided by the user, the first string is now different:
- (gdb) help set param-none
- Set the current value of 'param-none'.
- This command is not documented.
-
- # Only the class documentation is provided, the first string is
- # changed as in the previous case:
- (gdb) help set param-doc
- Set the current value of 'param-doc'.
- This is the class documentation string.
-
- # Only the set_doc and show_doc are provided, this case is unchanged
- # from before the patch:
- (gdb) help set param-set-show
- Set the state of this parameter
- This command is not documented.
-
- The one place where this change might be considered a negative is when
- dealing with prefix commands. If we create a prefix command but don't
- supply the set_doc / show_doc strings, then this is what we saw before
- my patch:
-
- (gdb) python Param_None ('print param-none')
- (gdb) help set print
- set print, set pr, set p
- Generic command for setting how things print.
-
- List of set print subcommands:
-
- ... snip ...
- set print param-none -- This command is not documented.
- ... snip ...
-
- And after my patch:
-
- (gdb) python Param_None ('print param-none')
- (gdb) help set print
- set print, set pr, set p
- Generic command for setting how things print.
-
- List of set print subcommands:
-
- ... snip ...
- set print param-none -- Set the current value of 'print param-none'.
- ... snip ...
-
- This seems slightly less helpful than before, but I don't think its
- terrible.
-
- Additionally, I've changed what we print when the get_show_string
- method is not provided in Python.
-
- Back when gdb.Parameter was first added to GDB, we didn't provide a
- show function when registering the internal command object within
- GDB. As a result, GDB would make use of its "magic" mangling of the
- show_doc string to create a sentence that would display the current
- value (see deprecated_show_value_hack in cli/cli-setshow.c).
-
- However, when we added support for the get_show_string method to
- gdb.Parameter, there was an attempt to maintain backward compatibility
- by displaying the show_doc string with the current value appended, see
- get_show_value in py-param.c. Unfortunately, this isn't anywhere
- close to what deprecated_show_value_hack does, and the results are
- pretty poor, for example, this is GDB before my patch:
-
- (gdb) show param-none
- This command is not documented. off
-
- I think we can all agree that this is pretty bad.
-
- After my patch, we how show this:
-
- (gdb) show param-none
- The current value of 'param-none' is "off".
-
- Which at least is a real sentence, even if it's not very informative.
-
- This patch does change the way that the Python API behaves slightly,
- but only in the cases when the user has missed providing GDB with some
- information. In most cases I think the new behaviour is a lot better,
- there's the one case (noted above) which is a bit iffy, but I think is
- still OK.
-
- I've updated the existing gdb.python/py-parameter.exp test to cover
- the modified behaviour.
-
- Finally, I've updated the documentation to (I hope) make it clearer
- how the various bits of help text come together.

- Reference array of structs instead of first member during memcpy
- aarch64-tdep.c defines the following macro:

- } \
- } \
- while (0)
-
- This is simlpy allocating a new array and copying it. However, for
- the destination address, it is actually copying into the first member
- of the first element of the array (`&MEMS->len"). This elicits a

- gdb: add string_file::release method
- A common pattern for string_file is to want to move out the internal
- string buffer, because it is the result of the computation that we want
- to return. It is the reason why string_file::string returns a non-const
- reference, as explained in the comment. I think it would make sense to
- have a dedicated method for that instead and make string_file::string
- return a const reference.
-
- This allows removing the explicit std::move in the typical case. Note
- that compile_program::compute was missing a move, meaning that the
- resulting string was copied. With the new version, it's not possible to
- forget to move.

- Add a way to temporarily set a gdb parameter from Python
- It's sometimes useful to temporarily set some gdb parameter from
- Python. Now that the 'endian' crash is fixed, and now that the
- current language is no longer captured by the Python layer, it seems
- reasonable to add a helper function for this situation.
-
- This adds a new gdb.with_parameter function. This creates a context
- manager which temporarily sets some parameter to a specified value.
- The old value is restored when the context is exited. This is most
- useful with the Python "with" statement:
-
- with gdb.with_parameter('language', 'ada'):
- ... do Ada stuff
-
- This also adds a simple function to set a parameter,
- gdb.set_parameter, as suggested by Andrew.

-
- Fix another crash with gdb parameters in Python
- While looking into the language-capturing issue, I found another way
- to crash gdb using parameters from Python:
-
- (gdb) python print(gdb.parameter('endian'))
-
- (This is related to PR python/12188, though this patch isn't going to
- fix what that bug is really about.)
-
- The problem here is that the global variable that underlies the
- "endian" parameter is initialized to NULL. However, that's not a
- valid value for an "enum" set/show parameter.
-
- My understanding is that, in gdb, an "enum" parameter's underlying
- variable must have a value that is "==" (not just strcmp-equal) to one
- of the values coming from the enum array. This invariant is relied on
- in various places.
-
- I started this patch by fixing the problem with "endian". Then I
- added some assertions to add_setshow_enum_cmd to try to catch other
- problems of the same type.
-
- This patch fixes all the problems that I found. I also looked at all
- the calls to add_setshow_enum_cmd to ensure that they were all
- included in the gdb I tested. I think they are: there are no calls in
- nat-* files, or in remote-sim.c; and I was trying a build with all
- targets, Python, and Guile enabled.

- language when "entering" Python code. This has some undesirable
- effects, and so this series changes how this is handled.
-
- First, there is code like this:
-
- gdbpy_enter enter_py (python_gdbarch, python_language);
-
- This is incorrect, because both of these are NULL when not otherwise
- assigned. This can cause crashes in some cases -- I've added one to
- the test suite. (Note that this crasher is just an example, other
- ones along the same lines are possible.)
-
- Second, when the language is captured in this way, it means that
- Python code cannot affect the current language for its own purposes.
- It's reasonable to want to write code like this:
-
- gdb.execute('set language mumble')
- ... stuff using the current language
- gdb.execute('set language previous-value')
-
- However, this won't actually work, because the language is captured on
- entry. I've added a test to show this as well.
-
- This patch changes gdb to try to avoid capturing the current values.
- The Python concept of the current gdbarch is only set in those few
- cases where a non-default value is computed or needed; and the
- language is not captured at all -- instead, in the cases where it's
- required, the current language is temporarily changed.

-2022-01-19 Maciej W. Rozycki <macro@embecosm.com>
-
- Respect `set print repeats' with Fortran arrays
- Implement `set print repeats' handling for Fortran arrays. Currently
- the setting is ignored and always treated as if no limit was set.
-
- Unlike the generic array walker implemented decades ago the Fortran one
- is a proper C++ class. Rather than trying to mimic the old walker then,
- which turned out a bit of a challenge where interacting with the `set
- print elements' setting, write it entirely from scratch, by adding an
- extra specialization handler method for processing dimensions other than
- the innermost one and letting the specialization class call the `walk_1'
- method from the handler as it sees fit. This way repeats can be tracked
- and the next inner dimension recursed into as a need arises only, or
- unconditionally in the base class.
-
- Keep track of the dimension number being handled in the class rather as
- a parameter to the walker so that it does not have to be passed across
- by the specialization class.
-
- Use per-dimension element count tracking, needed to terminate processing
- early when the limit set by `set print elements' is hit. This requires
- extra care too where the limit triggers exactly where another element
- that is a subarray begins. In that case rather than recursing we need
- to terminate processing or lone `(...)' would be printed. Additionally
- if the skipped element is the last one in the current dimension we need
- to print `...' by hand, because `continue_walking' won't print it at the
- upper level, because it can see the last element has already been taken
- care of.
-
- Preserve the existing semantics of `set print elements' where the total
- count of the elements handled is matched against the trigger level which
- is unlike with the C/C++ array printer where the per-dimension element
- count is used instead.
-
- Output now looks like:
-
- (gdb) set print repeats 4
- (gdb) print array_2d
- $1 = ((2, <repeats 5 times>) <repeats 5 times>)
- (gdb) set print elements 12
- (gdb) print array_2d
- $2 = ((2, <repeats 5 times>) (2, <repeats 5 times>) (2, 2, ...) ...)
- (gdb)
-
- for a 5 by 5 array filled with the value of 2.
-
- Amend existing test cases accordingly that rely on the current incorrect
- behavior and explicitly request that there be no limit for printing
- repeated elements there.
-
- Add suitable test cases as well covering sliced arrays in particular.

- Move "catch fork" to a new file
- The "catch fork" code is reasonably self-contained, and so this patch
- moves it out of breakpoint.c (the second largest source file in gdb)
- and into a new file, break-catch-fork.c.
-
- Unify "catch fork" and "catch vfork"
- I noticed that "catch fork" and "catch vfork" are nearly identical.
- This patch simplifies the code by unifying these two cases.
-
- Move gdb_regex to gdbsupport
- This moves the gdb_regex convenience class to gdbsupport.
-
- Introduce gdb-hashtab module in gdbsupport
- gdb has some extensions and helpers for working with the libiberty
- hash table. This patch consolidates these and moves them to
- gdbsupport.
-
- Move gdb obstack code to gdbsupport
- This moves the gdb-specific obstack code -- both extensions like
- obconcat and obstack_strdup, and things like auto_obstack -- to
- gdbsupport.
-
- Move gdb_argv to gdbsupport
- This moves the gdb_argv class to a new header in gdbsupport.
-
- Simplify event_location_probe
- event_location_probe currently stores two strings, but really only
- needs one. This patch simplifies it and removes some unnecessary
- copies as well.
-
- Use std::string in event_location
- This changes event_location to use std::string, removing some manual
- memory management, and an unnecessary string copy.
-
- Split event_location into subclasses
- event_location uses the old C-style discriminated union approach.
- However, it's better to use subclassing, as this makes the code
- clearer and removes some chances for error. This also enables future
- cleanups to avoid manual memory management and copies.
-
- Remove EL_* macros from location.c
- This patch removes the old-style EL_* macros from location.c. This
- cleans up the code by itself, IMO, but also enables further cleanups
- in subsequent patches.
-
- Boolify explicit_to_string_internal
- This changes explicit_to_string_internal to use 'bool' rather than
- 'int'.
-
- Remove a use of xfree in location.c
- This small cleanup removes a use of xfree from location.c, by
- switching to unique_xmalloc_ptr. One function is only used in
- location.c, so it is made static. And, another function is changed to
- avoid a copy.

- gdb: preserve `|` in connection details string
- Consider this GDB session:
-
- $ gdb -q
- (gdb) target remote | gdbserver - ~/tmp/hello.x
- Remote debugging using | gdbserver - ~/tmp/hello.x
- ... snip ...
- (gdb) info connections
- Num What Description
- * 1 remote gdbserver - ~/tmp/hello.x Remote target using gdb-specific protocol
- (gdb) python conn = gdb.selected_inferior().connection
- (gdb) python print(conn.details)
- gdbserver - ~/tmp/hello.x
- (gdb)
-
- I think there are two things wrong here, first in the "What" column of
- the 'info connections' output, I think the text should be:
-
- remote | gdbserver - ~/tmp/hello.x
-
- to correctly show the user how the connection was established. And in
- a similar fashion, I think that the `details` string of the
- gdb.TargetConnection object should be:
-
- | gdbserver - ~/tmp/hello.x
-
- This commit makes this change. Currently the '|' is detected and
- removed in gdb/serial.c. The string passed to the pipe_ops
- structure (from gdb/ser-pipe.c), doesn't then, contain the `|`, this
- is instead implied by the fact that it is a pipes based implementation
- of the serial_ops interface.
-
- After this commit we still detect the `|` in gdb/serial.c, but we now
- store the full string (including the `|`) in the serial::name member
- variable.
-
- For pipe based serial connections, this name is only used for
- displaying the two fields I mention above, and in pipe_open (from
- gdb/ser-pipe.c), and in pipe_open, we now know to skip over the `|`.
-
- The benefit I see from this change is that GDB's output now more
- accurately reflects the commands used to start a target, thus making
- it easier for a user to understand what is going on.

- gdb.dlang/demangle.exp: update expected output for _D8demangle4testFnZv
- Since commit ce2d3708bc8b ("Synchronize binutils libiberty sources with

-
- demangle _D8demangle4testFnZv^M
- demangle.test(typeof(null))^M
- (gdb) FAIL: gdb.dlang/demangle.exp: _D8demangle4testFnZv
-
- The commit imported the commit 0e32a5aa8bc9 ("libiberty: Add support for
- D `typeof(*null)' types") from the gcc repository. That commit includes
- an update to libiberty/testsuite/d-demangle-expected, which updates a
- test for the exact same mangled name:
-
- _D8demangle4testFnZv
- -demangle.test(none)
- +demangle.test(typeof(null))
-
- I don't know anything about D, but give that the change was made by Iain
- Buclaw, the D language maintainer, I trust him on that.
-
- Fix our test by updating the expected output in the same way.
-
- Note: it's not really useful to have all these D demangling tests in the
- GDB testsuite, since there are demangling tests in libiberty. We should
- consider removing them, but we first need to make sure that everything
- that is covered in gdb/testsuite/gdb.dlang/demangle.exp is also covered
- in libiberty/testsuite/d-demangle-expected.

- x86: drop ymmxmm_mode
- This enumerator is not used by any table entry.
-
- x86: share yet more VEX table entries with EVEX decoding
- On top of prior similar work more opportunities have appeared in the
- meantime. Note that this also happens to address the prior lack of
- decoding of EVEX.L'L for VMOV{L,H}P{S,D} and VMOV{LH,HL}PS.
-
- x86: consistently use scalar_mode for AVX512-FP16 scalar insns
- For some reason the original AVFX512F insns were not taken as a basis
- here, causing unnecessary divergence. While not an active issue, it is
- still relevant to note that OP_XMM() has special treatment of e.g.
- scalar_mode (marking broadcast as invalid). Such would better be
- consistent for all sufficiently similar insns.
-
- x86: record further wrong uses of EVEX.b
- For one EVEX.W set does not imply EVEX.b is uniformly valid. Reject it
- for modes which occur for insns allowing for EVEX.W to be set (noticed
- with VMOV{H,L}PD and VMOVDDUP, and only in AT&T mode, but not checked
- whether further insns would also have been impacted; I expect e.g.
- VCMPSD would have had the same issue). And then the present concept of
- broadcast makes no sense at all when the memory operand of an insn is
- the destination.

- x86: reduce AVX512 FP set of insns decoded through vex_w_table[]
- Like for AVX512-FP16, there's not that many FP insns where going through
- this table is easier / cheaper than using suitable macros. Utilize %XS
- and %XD more to eliminate a fair number of table entries.
-
- While doing this I noticed a few anomalies. Where lines get touched /
- moved anyway, these are being addressed right here:
- - vmovshdup used EXx for its 2nd operand, thus displaying seemingly
- valid broadcast when EVEX.b is set with a memory operand; use
- EXEvexXNoBcst instead just like vmovsldup already does
- - vmovlhps used EXx for its 3rd operand, when all sibling entries use
- EXq; switch to EXq there for consistency (the two differ only for
- memory operands)

- elf: Remove the 1-page gap before the RELRO segment
- The existing RELRO scheme may leave a 1-page gap before the RELRO segment
- and align the end of the RELRO segment to the page size:
-
- [18] .eh_frame PROGBITS 408fa0 008fa0 005e80 00 A 0 0 8
- [19] .init_array INIT_ARRAY 410de0 00fde0 000008 08 WA 0 0 8

- [23] .got.plt PROGBITS 411000 010000 000048 08 WA 0 0 8
-
- Instead, we can remove the 1-page gap if the maximum page size >= the
- maximum section alignment:
-
- [18] .eh_frame PROGBITS 408fa0 008fa0 005e80 00 A 0 0 8

- [23] .got.plt PROGBITS 410000 010000 000048 08 WA 0 0 8
-
- Because the end of the RELRO segment is always aligned to the page size
- and may not be moved, the RELRO segment size may be increased:
-
- [ 3] .dynstr STRTAB 000148 000148 000001 00 A 0 0 1

- gdb: don't use -Wmissing-prototypes with g++
- This commit aims to not make use of -Wmissing-prototypes when
- compiling with g++.
-
- Use of -Wmissing-prototypes was added with this commit:
-
- commit a0761e34f054767de6d6389929d27e9015fb299b
- Date: Wed Mar 11 15:15:12 2020 -0400
-
- gdb: enable -Wmissing-prototypes warning
-
- Because clang can provide helpful warnings with this flag.
- Unfortunately, g++ doesn't accept this flag, and will give this
- warning:
-
- cc1plus: warning: command line option ‘-Wmissing-prototypes’ is valid for C/ObjC but not for C++
-
- In theory the fact that this flag is not supported should be detected
- by the configure check in gdbsupport/warning.m4, but for users of
- ccache, this check doesn't work due to a long standing ccache issue:
-
- https://github.com/ccache/ccache/issues/738
-
- The ccache problem is that -W... options are reordered on the command
- line, and so -Wmissing-prototypes is seen before -Werror. Usually
- this doesn't matter, but the above warning (about the flag not being
- valid) is issued before the -Werror flag is processed, and so is not
- fatal.
-
- There have been two previous attempts to fix this that I'm aware of.
- The first is:
-
- https://sourceware.org/pipermail/gdb-patches/2021-September/182148.html
-
- In this attempt, instead of just relying on a compile to check if a
- flag is valid, the proposal was to both compile and link. As linking
- doesn't go through ccache, we don't suffer from the argument
- reordering problem, and the link phase will correctly fail when using
- -Wmissing-prototypes with g++. The configure script will then disable
- the use of this flag.
-
- This approach was rejected, and the suggestion was to only add the
- -Wmissing-prototypes flag if we are compiling with gcc.
-
- The second attempt, attempts this approach, and can be found here:
-
- https://sourceware.org/pipermail/gdb-patches/2021-November/183076.html
-
- This attempt only adds the -Wmissing-prototypes flag is the value of
- GCC is not 'yes'. This feels like it is doing the right thing,
- unfortunately, the GCC flag is really a 'is gcc like' flag, not a
- strict, is gcc check. As such, GCC is set to 'yes' for clang, which
- would mean the flag was not included for clang or gcc. The entire
- point of the original commit was to add this flag for clang, so
- clearly the second attempt is not sufficient either.
-
- In this new attempt I have added gdbsupport/compiler-type.m4, this
- file defines AM_GDB_COMPILER_TYPE. This macro sets the variable
- GDB_COMPILER_TYPE to either 'gcc', 'clang', or 'unknown'. In future
- the list of values might be extended to cover other compilers, if this
- is ever useful.
-
- I've then modified gdbsupport/warning.m4 to only add the problematic
- -Wmissing-prototypes flag if GDB_COMPILER_TYPE is not 'gcc'.
-
- I've tested this with both gcc and clang and see the expected results,
- gcc no longer attempts to use the -Wmissing-prototypes flag, while
- clang continues to use it.
-
- When compiling using ccache, I am no longer seeing the warning.

- gdb: add some extra debug information to attach_command
- While working on another patch I wanted to add some extra debug
- information to the attach_command function. This required me to add a
- new function to convert the thread_info::state variable to a string.
-
- The new debug might be useful to others, and the state to string
- function might be useful in other locations, so I thought I'd merge
- it.

- gdb: testsuite: make string[] type as char in gdb.base/charset.c
- This reverts the commit ff656e2e1cb1 ("gdb: testsuite: fix failed
- testcases in gdb.base/charset.exp").
-
- The original test code has no problem. On an architecture where
- char is signed, then both 'A' and ebcdic_us_string[7] will yield
- -63, which makes the equality true. On an architecture where char
- is unsigned, then both 'A' and ebcdic_us_string[7] will yield 193,
- which also makes the equality true.
-
- The test cases only failed on LoongArch. The default type of char
- is signed char on LoongArch, like x86-64. But when use gdb print
- command on LoongArch, the default type of char is unsigned char,
- this is wrong, I will look into it later, sorry for that.
-
- On LoongArch:
-
- $ cat test_char.c
- #include <stdio.h>
-
- int main()
- {
- char c1 = 193;
- unsigned char c2 = 193;
-
- printf("%d\n", c1);
- printf("%d\n", c1 == c2);
-
- return 0;
- }
- $ gcc test_char.c -o test_char
- $ ./test_char
- -63
- 0

- There are multiple problems around this:

- 1. The process_id variable is not initialized to a default value.

- x86: Add DT_RELR support
- DT_RELR is implemented with linker relaxation:
-
- 1. During linker relaxation, we scan input relocations with the same
- logic in relocate_section to determine if a relative relocation should
- be generated and save the relative relocation candidate information for
- sizing the DT_RELR section later after all symbols addresses can be
- determined. For these relative relocations which can't be placed in
- the DT_RELR section, they will be placed in the rela.dyn/rel.dyn
- section.
- 2. When DT_RELR is enabled, _bfd_elf_map_sections_to_segments calls a
- backend function to size the DT_RELR section which will compute the
- DT_RELR section size and tell ldelf_map_segments to layout sections
- again when the DT_RELR section size has been increased.
- 3. After regular symbol processing is finished, bfd_elf_final_link calls
- a backend function to finish the DT_RELR section.

- gdb: add 'maint set/show gnu-source-highlight enabled' command
- In a later commit I want to address an issue with the Python pygments
- based code styling solution. As this approach is only used when the
- GNU Source Highlight library is not available, testing bugs in this
- area can be annoying, as it requires GDB to be rebuilt with use of GNU
- Source Highlight disabled.
-
- This commit adds a pair of new maintenance commands:
-
- maintenance set gnu-source-highlight enabled on|off
- maintenance show gnu-source-highlight enabled
-
- these commands can be used to disable use of the GNU Source Highlight
- library, allowing me, in a later commit, to easily test bugs that
- would otherwise be masked by GNU Source Highlight being used.
-
- I made this a maintenance command, rather than a general purpose
- command, as it didn't seem like this was something a general user
- would need to adjust. We can always convert the maintenance command
- to a general command later if needed.
-
- There's no test for this here, but this feature will be used in a
- later commit.

- gdb: erase items from the source_cache::m_offset_cache
- The source_cache class has two member variables m_source_map, which
- stores the file contents, and m_offset_cache, which stores offsets
- into the file contents.
-
- As source files are read the contents of the file, as well as the
- offset data, are stored in the cache using these two member variables.
-
- Whenever GDB needs either the files contents, or the offset data,
- source_cache::ensure is called. This function looks for the file in
- m_source_map, and if it's found then this implies the file is also in
- m_offset_cache, and we're done.
-
- If the file is not in m_source_map then GDB calls
- source_cache::get_plain_source_lines to open the file and read its
- contents. ::get_plain_source_lines also calculates the offset data,
- which is then inserted into m_offset_cache.
-
- Back in ::ensure, the file contents are added into m_source_map. And
- finally, if m_source_map contains more than MAX_ENTRIES, an entry is
- removed from m_source_map.
-
- The problem is entries are not removed from m_offset_cache at the same
- time.
-
- This means that if a program contains enough source files, GDB will
- hold at most MAX_ENTRIES cached source file contents, but can contain
- offsets data for every source file.
-
- Now, the offsets data is going to be smaller than the cached file
- contents, so maybe there's no harm here. But, when we reload the file
- contents we always recalculate the offsets data. And, when we
- ::get_line_charpos asking for offset data we still call ::ensure which
- will ends up loading and caching the file contents.
-
- So, given the current code does the work of reloading the offset data
- anyway, we may as well save memory by capping m_offset_cache to
- MAX_ENTRIES just like we do m_source_map.
-
- That's what this commit does.
-
- There should be no user visible changes after this commit, except for
- ever so slightly lower memory usage in some cases.

- gdb: new 'maint flush source-cache' command
- This commit adds a new 'maint flush source-cache' command, this
- flushes the cache of source file contents.
-
- After flushing GDB is forced to reread source files the next time any
- source lines are to be displayed.
-
- I've added a test for this new feature. The test is a little weird,
- in that it modifies a source file after compilation, and makes use of
- the cache flush so that the changes show up when listing the source
- file. I'm not sure when such a situation would ever crop up in real
- life, but maybe we can imagine such cases.
-
- In reality, this command is useful for testing the syntax highlighting
- within GDB, we can adjust the syntax highlighting settings, flush the
- cache, and then get the file contents re-highlighted using the new
- settings.

- gdb: rename lin-lwp to linux-nat in set/show debug

-
- I've updated the documentation and help text to match, as well as
- making it clear that the debug that is coming out relates to all
- aspects of Linux native inferior support, not just the LWP aspect of
- it.
-
- The boundary between general "native" target debug, and the lwp
- specific part of that debug was always a little blurry, but the actual
- debug variable inside GDB is debug_linux_nat, and the print routine
- linux_nat_debug_printf, is used throughout the linux-nat.c file, not
- just for lwp related debug, so the new name seems to make more sense.

- I suspect that this was caused by the end of year date range update
- process.
-
- The Makefile.in contains two date ranges. The first range appears to
- be the date range for the version of automake being used, that is the
- range runs up to 2017 only, when automake 1.15.1 was released.
-
- The second date range in Makefile.in represents the date range for the
- generated file, and so, now runs up to 2022.
-
- Anyway, this is the result of running autoreconf (using automake
- 1.15.1) in the gdbsupport directory.

- XCOFF: add support for TLS relocations on hidden symbols
- This patch adds support for TLS relocation targeting C_HIDEXT symbols.
- In gas, TLS relocations, except R_TLSM and R_TLMSL, must keep the value
- of their target symbol.
- In ld, it simply ensures that internal TLS symbols are added to the
- linker hash table for xcoff_reloc_type_tls.
-
- It also improves the tests made by both.
-
- bfd/ChangeLog:
-
- * coff-rs6000.c (xcoff_howto_table): Fix name of R_TLSML.
- (xcoff_reloc_type_tls): Replace the error when h is NULL by
- an assert.
- (xcoff_complain_overflow_unsigned_func): Adjust comments.
- * coff64-rs6000.c (xcoff64_howto_table): Fix name of R_TLSML.
- * xcofflink.c (xcoff_link_add_symbols_to_hash_table): New
- function.
- (xcoff_link_add_symbols): Add C_HIDEXT TLS symbols to the linker
- hash table.
-
- gas/ChangeLog:
-
- * config/tc-ppc.c (md_apply_fix): Enable support for TLS
- relocation over internal symbols.

- Reduce use of unfiltered output in Darwin code
- The Darwin code uses unfiltered output liberally. This patch changes
- this code to send some output to gdb_stdlog (in some cases via the use
- of debug_prefixed_printf_cond_nofunc), or to gdb_stderr, or to simply
- switch to filtered output.
-
- Note that I didn't switch inferior_debug to use
- debug_prefixed_printf_cond_nofunc, because that would affect the
- output by removing the information about the inferior. I wasn't sure
- if this was important or not, so I left it in.
-
- v2 of this patch uses warning rather than prints to gdb_stderr, and
- removes some trailing whitespace.
-
- I can't compile this patch, so it's "best effort".

- gdb/hurd: handle inferiors exiting
- While testing on GNU/Hurd (i386) I noticed that GDB crashes when an
- inferior exits, with this error:
-
- inferior.c:293: internal-error: inferior* find_inferior_pid(process_stratum_target*, int): Assertion `pid != 0' failed.
-
- The problem appears to be in gnu_nat_target::wait.
-
- We always set inferior_ptid to null_ptid before calling target_wait,
- this has been the case since the multi-target changes were made to GDB
- in commit:
-
- commit 5b6d1e4fa4fc6827c7b3f0e99ff120dfa14d65d2
- Date: Fri Jan 10 20:06:08 2020 +0000

- Multi-target support
-
- With follow up changes in commit:
-
- commit 24ed6739b699f329c2c45aedee5f8c7d2f54e493
- Date: Thu Jan 30 14:35:40 2020 +0000
-
- gdb/remote: Restore support for 'S' stop reply packet
-
- Unfortunately, the GNU/Hurd target is still relying on the value of
- inferior_ptid in the case where an inferior exits - we return the
- value of inferior_ptid as the pid of the process that exited. This
- was fine in the single target world, where inferior_ptid identified
- the one running inferior, but this is no longer good enough.
-
- Instead, we should return a ptid containing the pid of the process
- that exited, as obtained from the wait event, and this is what this
- commit does.
-
- I've not run the full testsuite on GNU/Hurd as there appear to be lots
- of other issues with this target that makes running the full testsuite
- very painful, but I think this looks like a small easy improvement.

- ld: Extract _bfd_elf_link_iterate_on_relocs
- DT_RELR encodes consecutive R_*_RELATIVE relocations in GOT (the global
- offset table) and data sections in a compact format:
-
- https://groups.google.com/g/generic-abi/c/bX460iggiKg
-
- On some targets, R_*_RELATIVE relocations are counted and the GOT offsets
- are allocated when setting the dynamic section sizes after seeing all
- relocations. R_*_RELATIVE relocations are generated while relocating
- sections after section layout has been finalized.
-
- To prepare for DT_RELR implementation on these targets, extract
- _bfd_elf_link_iterate_on_relocs from _bfd_elf_link_check_relocs so
- that a backend can scan relocations in elf_backend_always_size_sections
-
- For x86 targets, the old check_relocs is renamed to scan_relocs and a
- new check_relocs is added to chek input sections and create dynamic
- relocation sections so that they will be mapped to output sections.
- scan_relocs is now called from elf_backend_always_size_sections.
-
- Since relocations are scanned after __start, __stop, .startof. and
- .sizeof. symbols have been finalized on x86, __[start|stop]_SECNAME for
- --gc-sections -z start-stop-gc are now zero when all SECNAME sections
- been garbage collected. This is no need for elf_x86_start_stop_gc_p.

-
- gdb: completion-support.exp: improve leading whitespace support
- There is a expect support library in the source tree designed to help
- developers test the auto-completion capabilities of GDB.
-
- One of the functions is test_gdb_complete_unique_re. It is used
- (usually indirectly via test_gdb_complete_unique) to test that a given
- input line is completed as a given output line. The test checks for two
- ways to do the completion: using tab-completion, or using the
- 'complete' command. To do this, calls to two dedicated functions are
- performed. If we omit few details, we can consider that a call to
-
- test_gdb_complete_unique $input $expected
-
- is equivalent to the two following calls:
-
- test_gdb_complete_tab_unique $input $expected
- test_gdb_complete_cmd_unique $input $expected
-
- When using the tab-completion, everything works as expected, but some
- care must be taken when using the 'complete' command if the given input
- has leading whitespaces. In such situation, the output of the
- 'complete' command will drop the leading whitespaces.
-
- The current approach is that in such situation, the input and expected
- outputs are right trimmed (i.e. all leading whitespaces are removed)
- when performing the command completion check.
-
- This means that the following call:
-
- test_gdb_complete_unique " $input" " $expected"
-
- is almost equivalent to (again, omitting few details and arguments):
-
- test_gdb_complete_tab_unique " $input" " $expected"
- test_gdb_complete_cmd_unique "$input" "$expected"
-
- This approach comes with a problem that we encounter when running the
- tests in complete-empty.exp. When doing so, we have:
-
- Running .../gdb/testsuite/gdb.base/complete-empty.exp ...
- DUPLICATE: gdb.base/complete-empty.exp: empty-input-line: cmd complete ""
-
- This is because the test file does something like:
-
- test_gdb_complete_unique "" "!" " " 1
- test_gdb_complete_unique " " " !" " " 1¬
-
- which, if we do the substitution introduced above is equivalent to:
-
- test_gdb_complete_tab_unique "" "!"
- test_gdb_complete_cmd_unique "" "!"
- test_gdb_complete_tab_unique " " " !"
- test_gdb_complete_cmd_unique "" "!"
-
- We see that the lines 2 and 4 are now the same, and for this reason the
- testing framework complains about DUPLICATE test names.
-
- To fix that, this commit proposes that instead of left trimming both
- input and expected outputs, only the expected output is trimmed.
-
- Care must be taken in the case the completion gives more possibilities
- than allowed by the max-completions setting. In this case, the input
- will be repeated in the output in its left trimmed version. This commit
- also ensures that this is taken care of.
-
- With this commit, the gdb.base/complete-empty.exp still passes all its
- tests but does not report the DUPLICATE anymore.

- Tested on x86_64-linux.

- Replace hand-written tests checking various comparison operators between
- various decimal floating point types with a loop to programmatically
- generate all the combinations. This removes the need to eyeball for all

-
- gdb/doc: shorten some source lines, and prevent some line breaks
- Building on the previous commit, this makes use of a trailing @ to
- split long @deffn lines in the guile.texi source file. This splitting
- doesn't change how the document is laid out by texinfo.
-
- I have also wrapped keyword and argument name pairs in @w{...} to
- prevent line breaks appearing between the two. I've currently only
- done this for the longer @deffn lines, where a line break is
- possible. This makes the @deffn lines much nicer to read in the
- generated pdf.
-
-2022-01-07 Andrew Burgess <aburgess@redhat.com>
-
- gdb/doc: Remove (...) around guile procedure names in @deffn lines
- Most guile procedures in the guile.texi file are defined like:
-
- @deffn {Scheme Procedure} name arg1 arg2 arg3
-
- But there are two places where we do this:
-
- @deffn {Scheme Procedure} (name arg1 arg2 arg3)
-
- Notice the added (...). Though this does represent how a procedure
- call is written in scheme, it's not the normal style throughout the
- manual. I also checked the 'info guile' info page to see how they
- wrote there declarations, and they use the first style too.
-
- The second style also has the drawback that index entries are added as
- '(name', and so they are grouped in the '(' section of the index,
- which is not very user friendly.
-
- In this commit I've changed the definitions of make-command and
- make-parameter to use the first style.
-
- The procedure declaration lines can get pretty long with all of the
- arguments, and this was true for both of the procedures I am changing
- in this commit. I have made use of a trailing '@' to split the deffn
- lines, and keep them under 80 characters in the texi source. This
- makes no difference to how the final document looks.
-
- Finally, our current style for keyword arguments, appears to be:
-
- [#:keyword-name argument-name]
-
- I don't really understand the reason for this, 'info guile' just seems
- to use:
-
- [#:keyword-name]
-
- which seems just as good to me. But I don't propose to change
- that just now. What I do notice though, is that sometimes, texinfo
- will place a line break between the keyword-name and the
- argument-name, for example, the pdf of make-command is:
-
- make-command name [#:invoke invoke] [#:command-class
- command-class] [#:completer-class completer] [#:prefix? prefix] [#:doc
- doc-string]
-
- Notice the line break after '#:command-class' and after '#:doc',
- neither of which are ideal. And so, for the two commands I am
- changing in this commit, I have made use of @w{...} to prevent line
- breaks between the keyword-name and the argument-name. Now the pdf
- looks like this:
-
- make-command name [#:invoke invoke]
- [#:command-class command-class] [#:completer-class completer]
- [#:prefix? prefix] [#:doc doc-string]
-
- Which seems much better. I'll probably update the other deffn lines
- at some point.

- Use target_announce_detach in more targets

- (For now, I left the couple targets that print this a bit differently
- alone. Maybe this could be further pulled out into infcmd.c. If we

- this new function could be converted to a target method.)
-
- It seems to me that the differences aren't very big, and in some cases
- other targets handled the output a bit more nicely. In particular,
- some targets will print a different message when exec_file==NULL,
- rather than printing the same output with an empty string as

- gdb: make use add_setshow_prefix_cmd in gnu-nat.c
- In gnu-nat.c we currently implement some set/show prefix commands
- "manually", that is, we call add_prefix_cmd, and assign a set and show
- function to each prefix command.
-
- These set/show functions print an error indicating that the user
- didn't type a complete command.
-
- If we instead switch to using add_setshow_prefix_cmd then we can
- delete the set/show functions, GDB provides some default functions,
- which give a nice help style summary that lists all of the available
- sub-commands, along with a one line summary of what each does.
-
- Though this clearly changes the existing behaviour, I think this
- change is acceptable as the new behaviour is more inline with other
- set/show prefix commands, and the new behaviour is more informative.
-
- This change will conflict with Tom's change here:
-
- https://sourceware.org/pipermail/gdb-patches/2022-January/184724.html
-
- Where Tom changes the set/show functions that I delete. My suggestion
- is that the set/show functions still be deleted even after Tom's
- patch (or instead of Tom's patch).
-
- For testing I've build GDB on GNU/Hurd, and manually tested these
- functions. I did a grep over the testsuite, and don't believe the
- existing error messages are being checked for in any tests.

- Change riscv_return_value to use RETURN_VALUE_ABI_PRESERVES_ADDRESS

- "return" part of this test fails.
-
- Joel tracked this down to riscv_return_value returning

- Filtered output cleanup in expression dumping
- Most of the expression-dumping code uses filtered output, but a few

-
- Note that this won't cause any behavior change, because the only calls

-
- Use filtered output in gnu-nat.c commands
- gnu-nat.c has a number of ordinary commands that should use filtered
- output. In a few cases, I changed the output to use gdb_stderr as
- well. I can't compile this file, so this patch is split out as a
- "best effort".
-
- Use filtered output in *-tdep commands
- Various targets introduce their own commands, which then use
- unfiltered output. It's better to use filtered output by default, so
- this patch fixes the instances I found.
-
- Use filtered output in btrace-related commands
- This changes btrace.c and record-btrace.c to use filtered output in
- the commands implemented there.
-
- Use filtered output in some dumping commands
- There are several commands that may optionally send their output to a
- file -- they take an optional filename argument and open a file. This
- patch changes these commands to use filtered output. The rationale
- here is that, when printing to gdb_stdout, filtering is appropriate --
- it is, and should be, the default for all commands. And, when writing
- to a file, paging will not happen anyway (it only happens when the
- stream==gdb_stdout), so using the _filtered form will not change
- anything.
-
- Use filtered output in kill command
- This changes the kill command to use filtered output. I split this
- one into its own patch because, out of an abundance of caution, I
- changed the function to call bfd_cache_close_all a bit earlier, in
- case pagination caused an exception.

- Use filtered output in ordinary commands
- Many otherwise ordinary commands choose to use unfiltered output
- rather than filtered. I don't think there's any reason for this, so

-
- Use filtered output in language_info
- Change language_info to use filtered output. This is ok because the
- sole caller uses filtered output elsewhere, and because this function
- calls show_language_command, which also uses filtered output.
-
- Use filtered output in files_info implementations
- This changes the implementations of the target files_info method to
- use filtered output. This makes sense because the sole caller of this
- method is an ordinary command (info_program_command). This patch
- changes this command to use filtered output as well.
-
- Use filtered output in target-descriptions.c
- target-descriptions.c uses unfiltered output. However, if you happen
- to invoke this command interactively, it's probably better for it to
- use filtering. For non-interactive use, this doesn't matter.
-
- Use filtered output for gdbarch dump
- This changes gdbarch dumping to use filtered output. This seems a bit
- better to me, both on the principle that this is an ordinary command,
- and because the output can be voluminous, so it may be nice to stop in
- the middle.

- This was discussed here:

- rather than the name when deciding to install a version-less symbol.
-
- The internal test case is identical to the catch_ex_std.exp that is

- Do not print anything when self-backtrace unavailable
- Right now, gdb's self-backtrace feature will still print something
- when a backtrace is unavailable:

- sig_write (_("----- Backtrace -----\n"));
- [...]
- sig_write (_("Backtrace unavailable\n"));
- sig_write ("---------------------\n");
-
- However, if GDB_PRINT_INTERNAL_BACKTRACE is undefined, it seems better
- to me to print nothing at all.
-
- This patch implements this change. It also makes a couple of other
- small changes in this same module: it adds a header guard to
- bt-utils.h, and it protects the definitions of
- gdb_internal_backtrace_1 with a check of GDB_PRINT_INTERNAL_BACKTRACE.

- Fix pager regression
- The patch to fix paging with redirection caused a regression in the
- internal AdaCore test suite. The problem occurs when running an MI
- command from the CLI using interpreter-exec, when paging is enabled.
- This scenario isn't covered by the current test suite, so this patch
- includes a new test.
-
- The problem is that, in this situation, MI does:
-
- fputs_unfiltered (strcmp (context->command, "target-select") == 0
- ? "^connected" : "^done", mi->raw_stdout);
-
- Here raw_stdout is a stdio_file wrapping stdout, so the pager thinks
- that it is ok to buffer the output. However, in this setup, it isn't
- ok, and flushing the wrap buffer doesn't really work properly. Also,
- MI next does:
-
- mi_out_put (uiout, mi->raw_stdout);
-
- ... but this uses ui_file::write, which also doesn't flush the wrap
- buffer.
-
- I think all this will be fixed by the pager rewrite series I'm working
- on. However, in the meantime, adding the old gdb_stdout check back to
- the pager fixes this problem.

- Regression tested on x86-64 Fedora 34.

- elf: Set p_align to the minimum page size if possible
- Currently, on 32-bit and 64-bit ARM, it seems that ld generates p_align
- values of 0x10000 even if no section alignment is greater than 0x1000.
- The issue is more general and probably affects other targets with multiple
- page sizes.
-
- While file layout absolutely must take 64K page size into account, that
- does not have to be reflected in the p_align value. If running on a 64K
- kernel, the file will be loaded at a 64K page boundary by necessity. On
- a 4K kernel, 64K alignment is not needed.
-
- The glibc loader has been fixed to honor p_align:
-
- https://sourceware.org/bugzilla/show_bug.cgi?id=28676
-
- similar to kernel:

-
- fs/binfmt_elf: use PT_LOAD p_align values for suitable start address
-
- This means that on 4K kernels, we will start to do extra work for 64K
- p_align, but this pointless for pretty much all binaries (whose section
- alignment rarely exceeds 16).
-
- The minimum page size is used, instead of the maximum section alignment
- due to this glibc bug:
-
- https://sourceware.org/bugzilla/show_bug.cgi?id=28688
-
- It has been fixed in glibc 2.35. But linker output must work on existing
- glibc binaries.
-
- 1. Set p_align to the minimum page size while laying out segments aligning
- to the maximum page size or section alignment. The run-time loader can
- align segments to the minimum page size or above, depending on system page
- size.
- 2. If -z max-page-size=NNN is used, p_align will be set to the maximum
- page size or the largest section alignment.
- 3. If a section requires alignment higher than the minimum page size,
- don't set p_align to the minimum page size.
- 4. If a section requires alignment higher than the maximum page size,
- set p_align to the section alignment.
- 5. For objcopy, when the minimum page size != the maximum page size,
- p_align may be set to the minimum page size while segments are aligned
- to the maximum page size. In this case, the input p_align will be
- ignored and the maximum page size will be used to align the ouput
- segments.
- 6. Update linker to disallow the common page size > the maximum page size.
- 7. Update linker to avoid the common page size > the maximum page size.
- 8. Adjust pru_irq_map-1.d to expect p_align == sh_addralign:

-
- On my GNU/Linux box, the man-page for sigwait doesn't mention that
- nullptr is allowed for the second argument, so my assumption would be
- that nullptr is not OK, and, if I change the '#ifdef
- HAVE_SIGTIMEDWAIT' introduced by the above patch to '#if 0', and
- rebuild on GNU/Linux, I see the same warning that I see on GNU/Hurd.
-
- I propose that we stop passing nullptr as the second argument to
- sigwait, and instead pass a valid int pointer. The value returned in
- the int can then be used in an assert.
-
- For testing, I (locally) made the change to the #ifdef I mentioned
- above, compiled GDB, and ran the usual tests, this meant I was using
- sigwait instead on sigtimedwait on GNU/Linux, I saw no regressions.

- x86/Intel: correct VFPCLASSP{S,D} handling when displacement is present
- fits_in_disp8() can be called before ambiguous operands get resolved
- or rejected (in process_suffix()), which requires that i.memshift be

- gas: rework handling of backslashes in quoted symbol names
- Strange effects can result from the present handling, e.g.:
-
- .if 1
- "backslash\\":
- .endif
-
- yields first (correctly) "missing closing `"'" but then also "invalid
- character '\' in mnemonic" and further "end of file inside conditional".
- Symbols names ending in \ are in principle not expressable with that
- scheme.
-
- Instead of recording whether a backslash was seen, inspect the
- subsequent character right away. Only accept \\ (meaning a single
- backslash in the resulting symbol name) and \" (meaning an embedded
- double quote in the resulting symbol name) for now, warning about any
- other combination.
-
- While perhaps not necessary immediately, also permit concatenated
- strings to form a symbol name. This may become useful if going forward
- we would want to support \<octal> or \x<hex> sequences, where closing
- and re-opening quotes can be useful to delimit such sequences.
-
- The ELF "Multibyte symbol names" test gets switched away from using
- .set, as that would now also mean excluding nios2 and pru. By using
- .equiv instead, even the existing #notarget can be dropped. (For h8300
- the .section directive additionally needs attributes specified, to avoid
- a target specific warning.)

- [gdb/cli] Improve show logging output
- Before commit 3b6acaee895 "Update more calls to add_prefix_cmd" we had the
- following output for "show logging":
- ...
- $ gdb -q -batch -ex "set trace-commands on" \
- -ex "set logging off" \
- -ex "show logging" \
- -ex "set logging on" \
- -ex "show logging"
- +set logging off
- +show logging
- Future logs will be written to gdb.txt.
- Logs will be appended to the log file.
- Output will be logged and displayed.
- Debug output will be logged and displayed.
- +set logging on
- +show logging
- Currently logging to "gdb.txt".
- Logs will be appended to the log file.
- Output will be logged and displayed.
- Debug output will be logged and displayed.
- ...
-
- After that commit we have instead:
- ...
- +set logging off
- +show logging
- debugredirect: The logging output mode is off.
- file: The current logfile is "gdb.txt".
- overwrite: Whether logging overwrites or appends to the log file is off.
- redirect: The logging output mode is off.
- +set logging on
- +show logging
- debugredirect: The logging output mode is off.
- file: The current logfile is "gdb.txt".
- overwrite: Whether logging overwrites or appends to the log file is off.
- redirect: The logging output mode is off.
- ...
- which gives less clear output for some subcommands.
-
- OTOH, it's explicit about whether boolean values are on or off.
-
- The new text seems to have been chosen to match the set/show help texts:
- ...
- (gdb) help show logging
- Show logging options.
-
- List of show logging subcommands:
-
- show logging debugredirect -- Show the logging debug output mode.
- show logging file -- Show the current logfile.
- show logging overwrite -- \
- Show whether logging overwrites or appends to the log file.
- show logging redirect -- Show the logging output mode.
- ...
-
- Make the show logging messages more clear, while still keep the boolean
- values explicit, such that we have:
- ...
- $ ./gdb.sh -q -batch -ex "show logging"
- logging debugredirect: off: \
- Debug output will go to both the screen and the log file.
- logging enabled: off: Logging is disabled.
- logging file: The current logfile is "gdb.txt".
- logging overwrite: off: Logging appends to the log file.
- logging redirect: off: Output will go to both the screen and the log file.

- gdb: Copy inferior properties in clone-inferior
- This commit ensures that the following settings are cloned from one
- inferior to the new one when processing the clone-inferior command:
- - inferior-tty
- - environment variables
- - cwd
- - args
-
- Some of those parameters can be passed as command line arguments to GDB
- (-args and -tty), so one could expect the clone-inferior to respect
- those flags. The following debugging session illustrates that:
-
- gdb -nx -quiet -batch \
- -ex "show args" \
- -ex "show inferior-tty" \
- -ex "clone-inferior" \
- -ex "inferior 2" \
- -ex "show args" \
- -ex "show inferior-tty" \
- -tty=/some/tty \
- -args echo foo bar
- Argument list to give program being debugged when it is started is "foo bar".
- Terminal for future runs of program being debugged is "/some/tty".
- [New inferior 2]
- Added inferior 2.
- [Switching to inferior 2 [<null>] (/bin/echo)]
- Argument list to give program being debugged when it is started is "".
- Terminal for future runs of program being debugged is "".
-
- The other properties this commit copies on clone (i.e. CWD and the
- environment variables) are included since they are related (in the sense
- that they influence the runtime behavior of the program) even if they
- cannot be directly set using command line switches.
-
- There is a chance that this patch changes existing user workflow. I
- think that this change is mostly harmless. If users want to start a new
- inferior based on an existing one, they probably already propagate those
- settings to the new inferior in some way.
-
- Tested on x86_64-linux.

- gdb/remote: handle attach when stop packet lacks thread-id
- Bug PR gdb/28405 reports a regression when using attach with an
- extended-remote target. In this case the target is not including a
- thread-id in the stop packet it sends back after the attach.
-
- The regression was introduced with this commit:
-
- commit 8f66807b98f7634c43149ea62e454ea8f877691d
- Date: Wed Jan 13 20:26:58 2021 -0500
-
- gdb: better handling of 'S' packets
-
- The problem is that when GDB processes the stop packet, it sees that
- there is no thread-id and so has to "guess" which thread the stop
- should apply to.
-
- In this case the target only has one thread, so really, there's no
- guessing needed, but GDB still runs through the same process, this
- shouldn't cause us any problems.
-
- However, after the above commit, GDB now expects itself to be more
- internally consistent, specifically, only a thread that GDB thinks is
- resumed, can be a candidate for having stopped.
-
- It turns out that, when GDB attaches to a process through an
- extended-remote target, the threads of the process being attached too,
- are not, initially, marked as resumed.
-
- And so, when GDB tries to figure out which thread the stop might apply
- too, it finds no threads in the processes marked resumed, and so an
- assert triggers.
-
- In extended_remote_target::attach we create a new thread with a call
- to add_thread_silent, rather than remote_target::remote_add_thread,
- the reason is that calling the latter will result in a call to
- 'add_thread' rather than 'add_thread_silent'. However,
- remote_target::remote_add_thread includes additional
- actions (i.e. calling remote_thread_info::set_resumed and set_running)
- which are missing from extended_remote_target::attach. These missing
- calls are what would serve to mark the new thread as resumed.
-
- In this commit I propose that we add an extra parameter to
- remote_target::remote_add_thread. This new parameter will force the
- new thread to be added with a call to add_thread_silent. We can now
- call remote_add_thread from the ::attach method, the extra
- actions (listed above) will now be performed, and the thread will be
- left in the correct state.
-
- Additionally, in PR gdb/28405, a segfault is reported. This segfault
- triggers when 'set debug remote 1' is used before trying to reproduce
- the original assertion failure. The cause of this is in
- remote_target::select_thread_for_ambiguous_stop_reply, where we do
- this:
-
- remote_debug_printf ("first resumed thread is %s",
- pid_to_str (first_resumed_thread->ptid).c_str ());
- remote_debug_printf ("is this guess ambiguous? = %d", ambiguous);
-
- gdb_assert (first_resumed_thread != nullptr);
-
- Notice that when debug printing is on we dereference
- first_resumed_thread before we assert that the pointer is not
- nullptr. This is the cause of the segfault, and is resolved by moving
- the assert before the debug printing code.
-
- I've extended an existing test, ext-attach.exp, so that the original
- test is run multiple times; we run in the original mode, as normal,
- but also, we now run with different packets disabled in gdbserver. In
- particular, disabling Tthread would trigger the assertion as it was
- reported in the original bug. I also run the test in all-stop and
- non-stop modes now for extra coverage, we also run the tests with
- target-async enabled, and disabled.

- gdb: on x86-64 non-trivial C++ objects are returned in memory
- Fixes PR gdb/28681. It was observed that after using the `finish`
- command an incorrect value was displayed in some cases. Specifically,
- this behaviour was observed on an x86-64 target.
-
- Consider this test program:
-
- struct A
- {
- int i;
-
- A ()
- { this->i = 0; }
- A (const A& a)
- { this->i = a.i; }
- };
-
- A
- func (int i)
- {
- A a;
- a.i = i;
- return a;
- }
-
- int
- main ()
- {
- A a = func (3);
- return a.i;
- }
-
- And this GDB session:
-
- $ gdb -q ex.x
- Reading symbols from ex.x...
- (gdb) b func
- Breakpoint 1 at 0x401115: file ex.cc, line 14.
- (gdb) r
- Starting program: /home/andrew/tmp/ex.x
-
- Breakpoint 1, func (i=3) at ex.cc:14
- 14 A a;
- (gdb) finish
- Run till exit from #0 func (i=3) at ex.cc:14
- main () at ex.cc:23
- 23 return a.i;
- Value returned is $1 = {
- i = -19044
- }
- (gdb) p a
- $2 = {
- i = 3
- }
- (gdb)
-
- Notice how after the `finish` the contents of $1 are junk, but, when I
- immediately ask for the value of `a`, I get back the correct value.
-
- The problem here is that after the finish command GDB calls the
- function amd64_return_value to figure out where the return value can
- be found (on x86-64 targets anyway).
-
- This function makes the wrong choice for the struct A in our case, as
- sizeof(A) <= 8, then amd64_return_value decides that A will be
- returned in a register. GDB then reads the return value register an
- interprets the contents as an instance of A.
-
- Unfortunately, A is not trivially copyable (due to its copy
- constructor), and the sys-v specification for argument and return
- value passing, says that any non-trivial C++ object should have space
- allocated for it by the caller, and the address of this space is
- passed to the callee as a hidden first argument. The callee should
- then return the address of this space as the return value.
-
- And so, the register that GDB is treating as containing an instance of
- A, actually contains the address of an instance of A (in this case on
- the stack), this is why GDB shows the incorrect result.
-
- The call stack within GDB for where we actually go wrong is this:
-
- amd64_return_value
- amd64_classify
- amd64_classify_aggregate
-
- And it is in amd64_classify_aggregate that we should be classifying
- the type as AMD64_MEMORY, instead of as AMD64_INTEGER as we currently
- do (via a call to amd64_classify_aggregate_field).
-
- At the top of amd64_classify_aggregate we already have this logic:
-
- if (TYPE_LENGTH (type) > 16 || amd64_has_unaligned_fields (type))
- {
- theclass[0] = theclass[1] = AMD64_MEMORY;
- return;
- }
-
- Which handles some easy cases where we know a struct will be placed
- into memory, that is (a) the struct is more than 16-bytes in size,
- or (b) the struct has any unaligned fields.
-
- All we need then, is to add a check here to see if the struct is
- trivially copyable. If it is not then we know the struct will be
- passed in memory.
-
- I originally structured the code like this:
-
- if (TYPE_LENGTH (type) > 16
- || amd64_has_unaligned_fields (type)
- || !language_pass_by_reference (type).trivially_copyable)
- {
- theclass[0] = theclass[1] = AMD64_MEMORY;
- return;
- }
-
- This solved the example from the bug, and my small example above. So
- then I started adding some more extensive tests to the GDB testsuite,
- and I ran into a problem. I hit this error:
-
- gdbtypes.h:676: internal-error: loc_bitpos: Assertion `m_loc_kind == FIELD_LOC_KIND_BITPOS' failed.
-
- This problem is triggered from:
-
- amd64_classify_aggregate
- amd64_has_unaligned_fields
- field::loc_bitpos
-
- Inside the unaligned field check we try to get the bit position of
- each field. Unfortunately, in some cases the field location is not
- FIELD_LOC_KIND_BITPOS, but is FIELD_LOC_KIND_DWARF_BLOCK.
-
- An example that shows this bug is:
-
- struct B
- {
- short j;
- };
-
- struct A : virtual public B
- {
- short i;
-
- A ()
- { this->i = 0; }
- A (const A& a)
- { this->i = a.i; }
- };
-
- A
- func (int i)
- {
- A a;
- a.i = i;
- return a;
- }
-
- int
- main ()
- {
- A a = func (3);
- return a.i;
- }
-
- It is the virtual base class, B, that causes the problem. The base
- class is represented, within GDB, as a field within A. However, the
- location type for this field is a DWARF_BLOCK.
-
- I spent a little time trying to figure out how to convert the
- DWARF_BLOCK to a BITPOS, however, I realised that, in this case at
- least, conversion is not needed.
-
- The C++ standard says that a class is not trivially copyable if it has
- any virtual base classes. And so, in this case, even if I could
- figure out the BITPOS for the virtual base class fields, I know for
- sure that I would immediately fail the trivially_copyable check. So,
- lets just reorder the checks in amd64_classify_aggregate to:
-
- if (TYPE_LENGTH (type) > 16
- || !language_pass_by_reference (type).trivially_copyable
- || amd64_has_unaligned_fields (type))
- {
- theclass[0] = theclass[1] = AMD64_MEMORY;
- return;
- }
-
- Now, if we have a class with virtual bases we will fail quicker, and
- avoid the unaligned fields check completely.

- gdb: make use of SCOPE_EXIT to manage thread executing state
- While working on another patch relating to how GDB manages threads
- executing and resumed state, I spotted the following code in
- record-btrace.c:
-
- executing = tp->executing ();
- set_executing (proc_target, inferior_ptid, false);
-
- id = null_frame_id;
- try
- {
- id = get_frame_id (get_current_frame ());
- }
- catch (const gdb_exception &except)
- {
- /* Restore the previous execution state. */
- set_executing (proc_target, inferior_ptid, executing);
-
- throw;
- }
-
- /* Restore the previous execution state. */
- set_executing (proc_target, inferior_ptid, executing);
-
- return id;
-
- I notice that we only catch the exception so we can call
- set_executing, and this is the same call to set_executing that we need
- to perform in the non-exception return path.
-
- This would be much cleaner if we could use SCOPE_EXIT to avoid the
- try/catch, so lets do that.
-
- While cleaning this up, I also applied a similar patch to
- record-full.c, though there's no try/catch in that case, but using
- SCOPE_EXIT makes the code safe if, in the future, we do start throwing
- exceptions.
-
- There should be no user visible changes after this commit.

- gdb/doc: add some index entries relating to mi-async setting
- I noticed that the mi-async setting was not referenced from the index

-
- The @cindex lines I think are not controversial, these same index
- entries are used elsewhere in the manual for async related topics (see

-
- The only bit that might be controversial is that I've added a @kindex
- entry for 'set mi-async' when the command is documented as '-gdb-set
- mi-async' (with a similar difference for the show/-gdb-show).
-
- My reasoning here is that nothing else is indexed under -gdb-set or
- -gdb-show, and as -gdb-set/-gdb-show are just the MI equivalent for
- set/show anything that is documented under set/show can be adjusted
- using -gdb-set/-gdbshow, and so, I've tried to keep the index

-
- set debug threads on|off
- show debug threads
-
- Prints additional debug information relating to thread creation and
- deletion.
-
- GDB already announces when threads are created of course.... most of
- the time, but sometimes threads are added silently, in which case this
- debug message is the only mechanism to see the thread being added.
- Also, though GDB does announce when a thread exits, it doesn't
- announce when the thread object is deleted, I've added a debug message
- for that.
-
- Additionally, having message printed through the debug system will
- cause the messages to be nested to an appropriate depth when other
- debug sub-systems are turned on (especially things like `infrun` and
- `lin-lwp`).

- gdb: add assert in remote_target::wait relating to async being off
- While working on another patch I ended up in a situation where I had
- async mode disabled (with 'maint set target-async off'), but the async
- event token got marked anyway.
-
- In this situation GDB was continually calling into
- remote_target::wait, however, the async token would never become
- unmarked as the unmarking is guarded by target_is_async_p.
-
- We could just unconditionally unmark the token, but that would feel
- like just ignoring a bug, so, instead, lets assert that if
- !target_is_async_p, then the async token should not be marked.
-
- This assertion would have caught my earlier mistake.
-
- There should be no user visible changes with this commit.

- gdb/remote: some fixes for 'maint set target-async off'
- While working on another patch relating to remote targets, I wanted to
- test with 'maint set target-async off' in place. Unfortunately I ran
- into some problems. This commit is an attempt to fix one of the
- issues I hit.
-
- In my particular case I was actually running with:
-
- maint set target-async off
- maint set target-non-stop off
-
- that is, we're telling GDB to force the targets to operate in
- non-async mode, and in all-stop mode. Here's my GDB session showing
- the problem:
-
- (gdb) maintenance set target-async off
- (gdb) maintenance set target-non-stop off
- (gdb) target extended-remote :54321
- Remote debugging using :54321
- (gdb) attach 2365960
- Attaching to process 2365960
- No unwaited-for children left.
- (gdb)
-
- Notice the 'No unwaited-for children left.' error, this is the
- problem. There's no reason why GDB should not be able to attach to
- the process.
-
- The problem is this:
-
- 1. The user runs 'attach PID' and this sends GDB into attach_command
- in infcmd.c. From here we call the ::attach method on the attach
- target, which will be the extended_remote_target.
-
- 2. In extended_remote_target::attach, we attach to the remote target
- and get the first reply (which is a stop packet). We put off
- processing the stop packet until the end of ::attach. We setup the
- inferior and thread to represent the process we attached to, and
- download the target description. Finally, we process the initial
- stop packet.
-
- If '!target_is_non_stop_p ()' and '!target_can_async_p ()', which is
- the case for us given the maintenance commands we used, we cache the
- stop packet within the remote_state::buf for later processing.
-
- 3. Back in attach_command, if 'target_is_non_stop_p ()' then we
- request that the target stops. This will either process any cached
- stop replies, or request that the target stops, and process the stop
- replies. However, this code is not what we use due to non-stop mode
- being disabled. So, we skip to the next step which is to call
- validate_exec_file.
-
- 4. Calling validate_exec_file can cause packets to be sent to the
- remote target, and replies received, the first path I hit is the
- call to target_pid_to_exec_file, which calls
- remote_target::pid_to_exec_file, which can then try to read the
- executable from the remote. Sending an receiving packets will make
- use of the remote_state::buf object.
-
- 5. The attempt to attach continues, but the damage is already done...
-
- So, the problem is that, in step #2 we cache a stop reply in the
- remote_state::buf, and then in step #4 we reuse the remote_state::buf
- object, discarding any cached stop reply. As a result, the initial
- stop, which is sent when GDB first attaches to the target, is lost.
-
- This problem can clearly be seen, I feel, by looking at the
- remote_state::cached_wait_status flag. This flag tells GDB if there
- is a wait status cached in remote_state::buf. However, in
- remote_target::putpkt_binary and remote_target::getpkt_or_notif_sane_1
- this flag is just set back to 0, doing this immediately discards any
- cached data.
-
- I don't know if this scheme ever made sense, looking at commit
- 2d717e4f8a54, where the cached_wait_status flag was added, it appears
- that there was nothing between where the stop was cached, and where
- the stop was consumed, so, I suspect, there never was a situation
- where we ended up in putpkt_binary or getpkt_or_notif_sane_1 and
- needed to clear to the flag, maybe the clearing was added "just in
- case". Whatever the history, I claim that this clearing this flag is
- no longer a good idea.
-
- So, my first step toward fixing this issue was to replace the two
- instances of 'rs->cached_wait_status = 0;' in ::putpkt_binary and
- ::getpkt_or_notif_sane_1 with 'gdb_assert (rs->cached_wait_status ==
- 0);', this, at least would show me when GDB was doing something
- dangerous, and indeed, this assert is now hit in my test case above.
-
- I did play with using some kind of scoped restore to backup, and
- restore the remote_state::buf object in all the places within remote.c
- that I was hitting where the ::buf was being corrupted. The first
- problem with this is that, where the ::cached_wait_status flag is
- reset is _not_ where ::buf is corrupted. For the ::putpkt_binary
- case, by the time we get to the method the buffer has already been
- corrupted in many cases, so we end up needing to add the scoped
- save/restore within the callers, which means we need the save/restore
- in _lots_ of places.
-
- Plus, using this save/restore model feels like the wrong solution. I
- don't think that it's obvious that the buffer might be holding cached
- data, and I think it would be too easy for new corruptions of the
- buffer to be introduced, which could easily go unnoticed for a long
- time.
-
- So, I really wanted a solution that didn't require us to cache data in
- the ::buf object.
-
- Luckily, I think we already have such a solution in place, the
- remote_state::stop_reply_queue, it seems like this does exactly the
- same task, just in a slightly different way. With the
- ::stop_reply_queue, the stop packets are processed upon receipt and
- the stop_reply object is added to the queue. With the ::buf cache
- solution, the unprocessed stop reply is cached in the ::buf, and
- processed later.
-
- So, finally, in this commit, I propose to remove the
- remote_state::cached_wait_status flag and to stop using the ::buf to
- cache stop replies. Instead, stop replies will now always be stored
- in the ::stop_reply_queue.
-
- There are two places where we use the ::buf to hold a cached stop
- reply, the first is in the ::attach method, and the second is in
- remote_target::start_remote, however, the second of these cases is far
- less problematic, as after caching the stop reply in ::buf we call the
- global start_remote function, which does very little work before
- calling normal_stop, which processes the cached stop reply. However,
- my plan is to switch both users over to using ::stop_reply_queue so
- that the old (unsafe) ::cached_wait_status mechanism can be completely
- removed.
-
- The next problem is that the ::stop_reply_queue is currently only used
- for async-mode, and so, in remote_target::push_stop_reply, where we
- push stop_reply objects into the ::stop_reply_queue, we currently also
- mark the async event token. I've modified this so we only mark the
- async event token if 'target_is_async_p ()' - note, _is_, not _can_
- here. The ::push_stop_reply method is called in places where async
- mode has been temporarily disabled, but, when async mode is switched
- back on (see remote_target::async) we will mark the event token if
- there are events in the queue.
-
- Another change of interest is in remote_target::remote_interrupt_as.
- Previously this code checked ::cached_wait_status, but didn't check
- for events in the ::stop_reply_queue. Now that ::cached_wait_status
- has been removed we now check the queue length instead, which should
- have the same result.
-
- Finally, in remote_target::wait_as, I've tried to merge the processing
- of the ::stop_reply_queue with how we used to handle the
- ::cached_wait_status flag.
-
- Currently, when processing the ::stop_reply_queue we call
- process_stop_reply and immediately return. However, when handling
- ::cached_wait_status we run through the whole of ::wait_as, and return
- at the end of the function.
-
- If we consider a standard stop packet, the two differences I see are:
-
- 1. Resetting of the remote_state::waiting_for_stop_reply, flag; this
- is not currently done when processing a stop from the
- ::stop_reply_queue.
-
- 2. The final return value has the possibility of being adjusted at
- the end of ::wait_as, as well as there being calls to
- record_currthread, non of which are done if we process a stop from
- the ::stop_reply_queue.
-
- After discussion on the mailing list:
-
- https://sourceware.org/pipermail/gdb-patches/2021-December/184535.html
-
- it was suggested that, when an event is pushed into the
- ::stop_reply_queue, the ::waiting_for_stop_reply flag is never going
- to be set. As a result, we don't need to worry about the first
- difference. I have however, added a gdb_assert to validate the
- assumption that the flag is never going to be set. If in future the
- situation ever changes, then we should find out pretty quickly.
-
- As for the second difference, I have resolved this by having all stop
- packets taken from the ::stop_reply_queue, pass through the return
- value adjustment code at the end of ::wait_as.
-
- An example of a test that reveals the benefits of this commit is:
-
- make check-gdb \
- RUNTESTFLAGS="--target_board=native-extended-gdbserver \
- GDBFLAGS='-ex maint\ set\ target-async\ off \
- -ex maint\ set\ target-non-stop\ off' \
- gdb.base/attach.exp"
-
- For testing I've been running test on x86-64/GNU Linux, and run with
- target boards unix, native-gdbserver, and native-extended-gdbserver.
- For each board I've run with the default GDBFLAGS, as well as with:
-
- GDBFLAGS='-ex maint\ set\ target-async\ off \
- -ex maint\ set\ target-non-stop\ off' \
-
- Though running with the above GDBFLAGS is clearly a lot more unstable
- both before and after my patch, I'm not seeing any consistent new
- failures with my patch, except, with the native-extended-gdbserver
- board, where I am seeing new failures, but only because more tests are
- now running. For that configuration alone I see the number of
- unresolved go down by 49, the number of passes goes up by 446, and the
- number of failures also increases by 144. All of the failures are new
- tests as far as I can tell.

- gdb/tui: install SIGWINCH only when connected to a TTY
- PR26056 reports that when GDB is connected to non-TTY stdin/stdout, it
- crashes when it receives a SIGWINCH signal.
-
- This can be reproduced as follows:
-
- $ gdb/gdb -nx -batch -ex 'run' --args sleep 60 </dev/null 2>&1 | cat
-
- # from another terminal:
- $ kill -WINCH %(pidof gdb)
-
- When doing so, the process crashes in a call to rl_resize_terminal:
-
- void
- rl_resize_terminal (void)
- {
- _rl_get_screen_size (fileno (rl_instream), 1);
- ...
- }
-
- The problem is that at this point rl_instream has the value NULL.
-
- The rl_instream variable is supposed to be initialized during a call to
- readline_initialize_everything, which in a normal startup sequence is
- called under this call chain:
-
- tui_interp::init
- tui_ensure_readline_initialized
- rl_initialize
- readline_initialize_everything
-
- In tui_interp::init, we have the following sequence:
-
- tui_initialize_io ();
- tui_initialize_win (); // <- Installs SIGWINCH
- if (gdb_stdout->isatty ())
- tui_ensure_readline_initialized (); // <- Initializes rl_instream
-
- This function unconditionally installs the SIGWINCH signal handler (this
- is done by tui_initialize_win), and then if gdb_stdout is a TTY it
- initializes readline. Therefore, if stdout is not a TTY, SIGWINCH is
- installed but readline is not initialized. In such situation
- rl_instream stays NULL, and when GDB receives a SIGWINCH it calls its
- handler and in fine tries to access rl_instream leading to the crash.
-
- This patch proposes to fix this issue by installing the SIGWINCH signal
- handler only if GDB is connected to a TTY. Given that this
- initialization it the only task of tui_initialize_win, this patch moves
- tui_initialize_win just after the call to
- tui_ensure_readline_initialized.
-
- Tested on x86_64-linux.

- xsnprintf: Assertion `ret < size' failed.
-
- Looking at the rest of the socket initialization code, the intent seems
- to be that if something goes wrong, we warn but let the program
- execute. So crashing on this failed assertions seems against the intent.
-
- Commit 6cebaf6e1ae4 ("use xsnprintf instead of snprintf.") changed this
- code to use xsnprintf instead of snprintf, introducing this assertion.
- Before that, snprintf would return a value bigger that UNIX_PATH_MAX and
- the "if" after would catch it and emit a warning, which is exactly what
- we want. That change was done because LynxOS didn't have snprintf.
- Since LynxOS isn't supported anymore, we can simply revert to use
- snprintf there.

- bfd: fix -Wunused errors with clang 13+
- Clang 13 and 14 produce some -Wunused-but-set-{variable,parameter} for
- situations where gcc doesn't. In particular, when a variable is set and
- then used in a way to update its own value. For example, if `i` is only
- used in this way:
-
- int i = 2;
- i++;
- i = i + 1;
-
- gcc won't warn, but clang will.
-
- Fix all such errors found in an --enable-targets=all build. It would be
- important for somebody who knows what they're doing to just make sure
- that these variables can indeed be deleted, and that there a no cases
- where it's a bug, and the variable should actually be used.

- gdb: improve reuse of value contents when fetching array elements
- While working on a Python script, which was interacting with a remote
- target, I noticed some weird slowness in GDB. In my program I had a
- structure something like this:
-
- struct foo_t
- {
- int array[5];
- };
-
- struct foo_t global_foo;
-
- Then in the Python script I was fetching a complete copy of global
- foo, like:
-
- val = gdb.parse_and_eval('global_foo')
- val.fetch_lazy()
-
- Then I would work with items in foo_t.array, like:
-
- print(val['array'][1])
-
- I called the fetch_lazy method specifically because I knew I was going
- to end up accessing almost all of the contents of val, and so I wanted
- GDB to do a single remote protocol call to fetch all the contents in
- one go, rather than trying to do lazy fetches for a couple of bytes at
- a time.
-
- What I observed was that, after the fetch_lazy call, GDB does,
- correctly, fetch the entire contents of global_foo, including all of
- the contents of array, however, when I access val.array[1], GDB still
- goes and fetches the value of this element from the remote target.
-
- What's going on is that in valarith.c, in value_subscript, for C like
- languages, we always end up treating the array value as a pointer, and
- then doing value_ptradd, and value_ind, the second of these calls
- always returns a lazy value.
-
- My guess is that this approach allows us to handle indexing off the
- end of an array, when working with zero element arrays, or when
- indexing a raw pointer as an array. And, I agree, that in these
- cases, where, even when the original value is non-lazy, we still will
- not have the content of the array loaded, we should be using the
- value_ind approach.
-
- However, for cases where we do have the array contents loaded, and we
- do know the bounds of the array, I think we should be using
- value_subscripted_rvalue, which is what we use for non C like
- languages.
-
- One problem I did run into, exposed by gdb.base/charset.exp, was that
- value_subscripted_rvalue stripped typedefs from the element type of
- the array, which means the value returned will not have the same type
- as an element of the array, but would be the raw, non-typedefed,
- type. In charset.exp we got back an 'int' instead of a
- 'wchar_t' (which is a typedef of 'int'), and this impacts how we print
- the value. Removing typedefs from the resulting value just seems
- wrong, so I got rid of that, and I don't see any test regressions.
-
- With this change in place, my original Python script is now doing no
- additional memory accesses, and its performance increases about 10x!

- gdb: make post_startup_inferior a virtual method on inf_ptrace_target
- While working on a later patch that required me to understand how GDB
- starts up inferiors, I was confused by the
- target_ops::post_startup_inferior method.
-
- The post_startup_inferior target function is only called from
- inf_ptrace_target::create_inferior.
-
- Part of the target class hierarchy looks like this:
-
- inf_child_target
- |
- '-- inf_ptrace_target
- |
- |-- linux_nat_target
- |
- |-- fbsd_nat_target
- |
- |-- nbsd_nat_target
- |
- |-- obsd_nat_target
- |
- '-- rs6000_nat_target
-
- Every sub-class of inf_ptrace_target, except rs6000_nat_target,
- implements ::post_startup_inferior. The rs6000_nat_target picks up
- the implementation of ::post_startup_inferior not from
- inf_ptrace_target, but from inf_child_target.
-
- No descendent of inf_child_target, outside the inf_ptrace_target
- sub-tree, implements ::post_startup_inferior, which isn't really
- surprising, as they would never see the method called (remember, the
- method is only called from inf_ptrace_target::create_inferior).
-
- What I find confusing is the role inf_child_target plays in
- implementing, what is really a helper function for just one of its
- descendents.
-
- In this commit I propose that we formally make ::post_startup_inferior
- a helper function of inf_ptrace_target. To do this I will remove the
- ::post_startup_inferior from the target_ops API, and instead make this
- a protected, pure virtual function on inf_ptrace_target.
-
- I'll remove the empty implementation of ::post_startup_inferior from
- the inf_child_target class, and add a new empty implementation to the
- rs6000_nat_target class.
-
- All the other descendents of inf_ptrace_target already provide an
- implementation of this method and so don't need to change beyond
- making the method protected within their class declarations.
-
- To me, this makes much more sense now. The helper function, which is
- only called from within the inf_ptrace_target class, is now a part of
- the inf_ptrace_target class.
-
- The only way in which this change is visible to a user is if the user
- turns on 'set debug target 1'. With this debug flag on, prior to this
- patch the user would see something like:
-
- -> native->post_startup_inferior (...)
- <- native->post_startup_inferior (2588939)
-
- After this patch these lines are no longer present, as the
- post_startup_inferior is no longer a top level target method. For me,
- this is an acceptable change.

- gdb: have mips_nbsd_nat_target inherit from nbsd_nat_target
- While working on another patch I had reason to look at
- mips-netbsd-nat.c, and noticed that the class mips_nbsd_nat_target
- inherits directly from inf_ptrace_target.
-
- This is a little strange as alpha_bsd_nat_target,
- arm_netbsd_nat_target, hppa_nbsd_nat_target, m68k_bsd_nat_target,
- ppc_nbsd_nat_target, sh_nbsd_nat_target, and vax_bsd_nat_target all
- inherit from nbsd_nat_target.
-
- Originally, in this commit:
-
- commit f6ac5f3d63e03a81c4ff3749aba234961cc9090e
- Date: Thu May 3 00:37:22 2018 +0100
-
- Convert struct target_ops to C++
-
- When the target tree was converted to C++, all of the above classes
- inherited from inf_ptrace_target except for hppa_nbsd_nat_target,
- which was the only class that originally inherited from
- nbsd_nat_target.
-
- Later on all the remaining targets (except mips) were converted to
- inherit from nbsd_nat_target, these are the commits:
-
- commit 4fed520be264b60893aa674071947890f8172915

-
- Inherit vax_bsd_nat_target from nbsd_nat_target
-
- I could only find mailing list threads for ppc and sh in the archive ,
- and unfortunately, none of the commits has any real detail that might
- explain why mips was missed out, the only extra context I could find
- was this message:
-
- https://sourceware.org/pipermail/gdb-patches/2020-March/166853.html
-
- Which says that "proper" OS support is going to be added to
- nbsd_nat_target, hence the need to inherit from that class.
-
- My guess is that leaving mips_nbsd_nat_target unchanged was an
- oversight, so, in this commit, I propose changing mips_nbsd_nat_target
- to inherit from nbsd_nat_target just like all the other nbsd targets.
-
- My motivation for this patch relates to the post_startup_inferior
- target method. In a future commit I want to change how this method is
- handled. Currently the mips_nbsd_nat_target will pick up the empty
- implementation of inf_child_target::post_startup_inferior rather than
- the version in netbsd-nat.c. This feels like a bug to me, as surely,
- enabling of proc events is something that would need to be done for
- all netbsd targets, regardless of architecture.
-
- In my future patch I have a choice then, either (a) add a new, empty
- implementation of post_startup_inferior to mips_nbsd_nat_target,
- or (b) this commit, have mips_nbsd_nat_target inherit from
- nbsd_nat_target. Option (b) seems like the right way to go, hence,
- this commit.
-
- I've done absolutely no testing for this change, not even building it,
- as that would require at least an environment in which I can x-build
- mips-netbsd applications, which I have no idea how to set up.

- gdb: only include mips and riscv targets if building with 64-bit bfd
- While testing another patch I was trying to build different
- configurations of GDB, and, during one test build I ran into a
- problem, I configured with `--enable-targets=all
- --host=i686-w64-mingw32` and saw this error while linking GDB:
-
- .../i686-w64-mingw32/bin/ld: mips-tdep.o: in function `mips_gdbarch_init':
- .../src/gdb/mips-tdep.c:8730: undefined reference to `disassembler_options_mips'
- .../i686-w64-mingw32/bin/ld: riscv-tdep.o: in function `riscv_gdbarch_init':
- .../src/gdb/riscv-tdep.c:3851: undefined reference to `disassembler_options_riscv'
-
- So the `disassembler_options_mips` and `disassembler_options_riscv`
- symbols are missing.
-
- This turns out to be because mips-dis.c and riscv-dis.c, in which
- these symbols are defined, are in the TARGET64_LIBOPCODES_CFILES list
- in opcodes/Makefile.am, these files are only built when we are
- building with a 64-bit bfd.
-
- If we look further, into bfd/Makefile.am, we can see that all the
- files matching elf*-riscv.lo are in the BFD64_BACKENDS list, as are
- the elf*-mips.lo files, and (I know because I tried), the two
- disassemblers do, not surprisingly, depend on features supplied from
- libbfd.
-
- So, though we can build most of GDB just fine for riscv and mips with
- a 32-bit bfd, if I understand correctly, the final GDB
- executable (assuming we could get it to link) would not understand
- these architectures at the bfd level, nor would there be any
- disassembler available. This sounds like a pretty useless GDB to me.
-
- So, in this commit, I move the riscv and mips targets into GDB's list
- of targets that require a 64-bit bfd. After this I can build GDB just
- fine with the configure options given above.
-
- This was discussed on the mailing list in a couple of threads:
-
- https://sourceware.org/pipermail/gdb-patches/2021-December/184365.html
- https://sourceware.org/pipermail/binutils/2021-November/118498.html
-
- and it is agreed, that it is unfortunate that the 32-bit riscv and
- 32-bit mips targets require a 64-bit bfd. If in the future this
- situation ever changes then it would be expected that some (or all) of
- this patch would be reverted. Until then though, this patch allows
- GDB to build when configured with --enable-targets=all, and when using
- a 32-bit libbfd.

- gdb/testsuite: fix default behavior of runto
- The documented behavior of proc runto is to not emit a PASS when
- succeeding to to run to the specified location, but emit a FAIL when
- failing to do so. I suppose the intent is that it won't pollute the
- results normally passing tests (although I don't see why we would care),
- but make visible any problems.
-
- However, it seems like the implementation makes it default to never
- print anything. "no-message" is prependend to "args", so if "message"
- is not passed, we will always take the path that sets print_fail to 0,
- which will silence any failure.
-
- This unfortunately means that tests relying on runto_main won't emit a
- FAIL if failing to run to main. And since commit 4dfef5be6812
- ("gdb/testsuite: make runto_main not pass no-message to runto"), tests
- don't emit a FAIL themselves when failing to run to main. This means
- that tests failing to run to main just fail silently, and that's bad.
-
- This can be reproduced by hacking gdb.base/template.exp like so:
-
- diff --git a/gdb/testsuite/gdb.base/template.c b/gdb/testsuite/gdb.base/template.c
- index bcf39c377d92..052be5b79d73 100644

- gdb, gdbserver: detach fork child when detaching from fork parent
- While working with pending fork events, I wondered what would happen if
- the user detached an inferior while a thread of that inferior had a
- pending fork event. What happens with the fork child, which is
- ptrace-attached by the GDB process (or by GDBserver), but not known to
- the core? Sure enough, neither the core of GDB or the target detach the
- child process, so GDB (or GDBserver) just stays ptrace-attached to the
- process. The result is that the fork child process is stuck, while you
- would expect it to be detached and run.
-
- Make GDBserver detach of fork children it knows about. That is done in
- the generic handle_detach function. Since a process_info already exists
- for the child, we can simply call detach_inferior on it.
-
- GDB-side, make the linux-nat and remote targets detach of fork children
- known because of pending fork events. These pending fork events can be
- stored in:
-
- - thread_info::pending_waitstatus, if the core has consumed the event
- but then saved it for later (for example, because it got the event
- while stopping all threads, to present an all-stop stop on top of a
- non-stop target)
- - thread_info::pending_follow: if we ran to a "catch fork" and we
- detach at that moment
-
- Additionally, pending fork events can be in target-specific fields:
-
- - For linux-nat, they can be in lwp_info::status and
- lwp_info::waitstatus.
- - For the remote target, they could be stored as pending stop replies,
- saved in `remote_state::notif_state::pending_event`, if not
- acknowledged yet, or in `remote_state::stop_reply_queue`, if
- acknowledged. I followed the model of remove_new_fork_children for
- this: call remote_notif_get_pending_events to process /
- acknowledge any unacknowledged notification, then look through
- stop_reply_queue.
-
- Update the gdb.threads/pending-fork-event.exp test (and rename it to
- gdb.threads/pending-fork-event-detach.exp) to try to detach the process
- while it is stopped with a pending fork event. In order to verify that
- the fork child process is correctly detached and resumes execution
- outside of GDB's control, make that process create a file in the test
- output directory, and make the test wait $timeout seconds for that file
- to appear (it happens instantly if everything goes well).
-
- This test catches a bug in linux-nat.c, also reported as PR 28512
- ("waitstatus.h:300: internal-error: gdb_signal target_waitstatus::sig()
- const: Assertion `m_kind == TARGET_WAITKIND_STOPPED || m_kind ==
- TARGET_WAITKIND_SIGNALLED' failed.). When detaching a thread with a
- pending event, get_detach_signal unconditionally fetches the signal
- stored in the waitstatus (`tp->pending_waitstatus ().sig ()`). However,
- that is only valid if the pending event is of type
- TARGET_WAITKIND_STOPPED, and this is now enforced using assertions (iit
- would also be valid for TARGET_WAITKIND_SIGNALLED, but that would mean
- the thread does not exist anymore, so we wouldn't be detaching it). Add
- a condition in get_detach_signal to access the signal number only if the
- wait status is of kind TARGET_WAITKIND_STOPPED, and use GDB_SIGNAL_0
- instead (since the thread was not stopped with a signal to begin with).
-
- Add another test, gdb.threads/pending-fork-event-ns.exp, specifically to
- verify that we consider events in pending stop replies in the remote
- target. This test has many threads constantly forking, and we detach
- from the program while the program is executing. That gives us some
- chance that we detach while a fork stop reply is stored in the remote
- target. To verify that we correctly detach all fork children, we ask
- the parent to exit by sending it a SIGUSR1 signal and have it write a
- file to the filesystem before exiting. Because the parent's main thread
- joins the forking threads, and the forking threads wait for their fork
- children to exit, if some fork child is not detach by GDB, the parent
- will not write the file, and the test will time out. If I remove the
- new remote_detach_pid calls in remote.c, the test fails eventually if I
- run it in a loop.
-
- There is a known limitation: we don't remove breakpoints from the
- children before detaching it. So the children, could hit a trap
- instruction after being detached and crash. I know this is wrong, and
- it should be fixed, but I would like to handle that later. The current
- patch doesn't fix everything, but it's a step in the right direction.

- gdb: move clearing of tp->pending_follow to follow_fork_inferior
- A following patch will change targets so that when they detach an
- inferior, they also detach any pending fork children this inferior may
- have. While doing this, I hit a case where we couldn't differentiate
- two cases, where in one we should detach the fork detach but not in the
- other.
-
- Suppose we continue past a fork with "follow-fork-mode == child" &&
- "detach-on-fork on". follow_fork_inferior calls target_detach to detach
- the parent. In that case the target should not detach the fork
- child, as we'll continue debugging the child. As of now, the
- tp->pending_follow field of the thread who called fork still contains
- the details about the fork.
-
- Then, suppose we run to a fork catchpoint and the user types "detach".
- In that case, the target should detach the fork child in addition to the
- parent. In that case as well, the tp->pending_follow field contains
- the details about the fork.
-
- To allow targets to differentiate the two cases, clear
- tp->pending_follow a bit earlier, when following a fork. Targets will
- then see that tp->pending_follow contains TARGET_WAITKIND_SPURIOUS, and
- won't detach the fork child.
-
- As of this patch, no behavior changes are expected.

-
- - Pass an inferior to kill_new_fork_children instead of a pid. That

- filtering on the thread's pid.
- - Change thread_pending_fork_status to return a non-nullptr value only
- if the thread does have a pending fork status.
- - Remove is_pending_fork_parent_thread, as one can just use
- thread_pending_fork_status and check for nullptr.
- - Replace is_pending_fork_parent with is_fork_status, which just
- returns if the given target_waitkind if a fork or a vfork. Push
- filtering on the pid to the callers, when it is necessary.

- - We are using the all-stop user-visible mode as well as the
- synchronous / all-stop variant of the remote protocol
- - We have two threads, thread A that we single-step and thread B that
- calls fork at the same time
- - GDBserver's linux_process_target::wait pulls the "single step
- complete SIGTRAP" and the "fork" events from the kernel. It
- arbitrarily choses one event to report, it happens to be the
- single-step SIGTRAP. The fork stays pending in the thread_info.
- - GDBserver send that SIGTRAP as a stop reply to GDB
- - While in stop_all_threads, GDB calls update_thread_list, which ends
- up querying the remote thread list using qXfer:threads:read.
- - In the reply, GDBserver includes the fork child created as a result
- of thread B's fork.
- - GDB-side, the remote target sees the new PID, calls
- remote_notice_new_inferior, which ends up unexpectedly creating a new
- inferior, and things go downhill from there.
-
- The problem here is that as long as GDB did not process the fork event,
- it should pretend the fork child does not exist. Ultimately, this event
- will be reported, we'll go through follow_fork, and that process will be
- detached.
-
- The remote target (GDB-side), has some code to remove from the reported
- thread list the threads that are the result of forks not processed by
- GDB yet. But that only works for fork events that have made their way
- to the remote target (GDB-side), but haven't been consumed by the core
- yet, so are still lingering as pending stop replies in the remote target
- (see remove_new_fork_children in remote.c). But in our case, the fork
- event hasn't made its way to the GDB-side remote target. We need to
- implement the same kind of logic GDBserver-side: if there exists a
- thread / inferior that is the result of a fork event GDBserver hasn't
- reported yet, it should exclude that thread / inferior from the reported
- thread list.
-
- This was actually discussed a while ago, but not implemented AFAIK:
-
- https://pi.simark.ca/gdb-patches/1ad9f5a8-d00e-9a26-b0c9-3f4066af5142@redhat.com/#t
- https://sourceware.org/pipermail/gdb-patches/2016-June/133906.html
-
- Implementation details-wise, the fix for this is all in GDBserver. The
- Linux layer of GDBserver already tracks unreported fork parent / child
- relationships using the lwp_info::fork_relative, in order to avoid
- wildcard actions resuming fork childs unknown to GDB. This information
- needs to be made available to the handle_qxfer_threads_worker function,
- so it can filter the reported threads. Add a new thread_pending_parent
- target function that allows the Linux target to return the parent of an
- eventual fork child.
-
- Testing-wise, the test replicates pretty-much the sequence of events
- shown above. The setup of the test makes it such that the main thread
- is about to fork. We stepi the other thread, so that the step completes
- very quickly, in a single event. Meanwhile, the main thread is resumed,
- so very likely has time to call fork. This means that the bug may not
- reproduce every time (if the main thread does not have time to call
- fork), but it will reproduce more often than not. The test fails
- without the fix applied on the native-gdbserver and
- native-extended-gdbserver boards.
-
- At some point I suspected that which thread called fork and which thread
- did the step influenced the order in which the events were reported, and
- therefore the reproducibility of the bug. So I made the test try both
- combinations: main thread forks while other thread steps, and vice
- versa. I'm not sure this is still necessary, but I left it there
- anyway. It doesn't hurt to test a few more combinations.

- gdb/python: Use tp_init instead of tp_new to setup gdb.Value
- The documentation suggests that we implement gdb.Value.__init__,
- however, this is not currently true, we really implement
- gdb.Value.__new__. This will cause confusion if a user tries to
- sub-class gdb.Value. They might write:
-
- class MyVal (gdb.Value):
- def __init__ (self, val):
- gdb.Value.__init__(self, val)
-
- obj = MyVal(123)
- print ("Got: %s" % obj)
-
- But, when they source this code they'll see:
-
- (gdb) source ~/tmp/value-test.py
- Traceback (most recent call last):
- File "/home/andrew/tmp/value-test.py", line 7, in <module>
- obj = MyVal(123)
- File "/home/andrew/tmp/value-test.py", line 5, in __init__
- gdb.Value.__init__(self, val)
- TypeError: object.__init__() takes exactly one argument (the instance to initialize)
- (gdb)
-
- The reason for this is that, as we don't implement __init__ for
- gdb.Value, Python ends up calling object.__init__ instead, which
- doesn't expect any arguments.
-
- The Python docs suggest that the reason why we might take this
- approach is because we want gdb.Value to be immutable:
-
- https://docs.python.org/3/c-api/typeobj.html#c.PyTypeObject.tp_new
-
- But I don't see any reason why we should require gdb.Value to be
- immutable when other types defined in GDB are not. This current
- immutability can be seen in this code:
-
- obj = gdb.Value(1234)
- print("Got: %s" % obj)
- obj.__init__ (5678)
- print("Got: %s" % obj)
-
- Which currently runs without error, but prints:
-
- Got: 1234
- Got: 1234
-
- In this commit I propose that we switch to using __init__ to
- initialize gdb.Value objects.
-
- This does introduce some additional complexity, during the __init__
- call a gdb.Value might already be associated with a gdb value object,
- in which case we need to cleanly break that association before
- installing the new gdb value object. However, the cost of doing this
- is not great, and the benefit - being able to easily sub-class
- gdb.Value seems worth it.
-
- After this commit the first example above works without error, while
- the second example now prints:
-
- Got: 1234
- Got: 5678
-
- In order to make it easier to override the gdb.Value.__init__ method,
- I have tweaked the definition of gdb.Value.__init__. The second,
- optional argument to __init__ is a gdb.Type, if this argument is not
- present then GDB figures out a suitable type.
-
- However, if we want to override the __init__ method in a sub-class,
- and still support the default argument, it is easier to write:
-
- class MyVal (gdb.Value):
- def __init__ (self, val, type=None):
- gdb.Value.__init__(self, val, type)
-
- Currently, passing None for the Type will result in an error:
-
- TypeError: type argument must be a gdb.Type.
-
- After this commit I now allow the type argument to be None, in which
- case GDB figures out a suitable type just as if the type had not been
- passed at all.
-
- Unless a user is trying to reinitialize a value, or create sub-classes
- of gdb.Value, there should be no user visible changes after this
- commit.

- gdb: use try/catch around a gdb_disassembler::print_insn call
- While investigating some disassembler problems I ran into this case;
- GDB compiled on a 32-bit arm target, with --enable-targets=all. Then
- in GDB:
-
- (gdb) set architecture i386
- (gdb) disassemble 0x0,+4
- unknown disassembler error (error = -1)
-
- This is interesting because it shows a case where the libopcodes
- disassembler is returning -1 without first calling the
- memory_error_func callback. Indeed, the return from libopcodes
- happens from this code snippet in i386-dis.c in the print_insn
- function:
-
- if (address_mode == mode_64bit && sizeof (bfd_vma) < 8)
- {
- (*info->fprintf_func) (info->stream,
- _("64-bit address is disabled"));
- return -1;
- }
-
- Notice how, prior to the return the disassembler tries to print a
- helpful message out, but GDB doesn't print this message.
-
- The reason this message goes missing is the call stack, it looks like
- this:
-
- gdb_pretty_print_disassembler::pretty_print_insn
- gdb_disassembler::print_insn
- gdbarch_print_insn
- ...
- i386-dis.c:print_insn
-
- When i386-dis.c:print_insn returns -1 this is handled in
- gdb_disassembler::print_insn, where an exception is thrown. However,
- the actual printing of the disassembler output is done in
- gdb_pretty_print_disassembler::pretty_print_insn, and is only done if
- an exception is not thrown.
-
- In this commit I change this. The pretty_print_insn now uses
- try/catch around the call to gdb_disassembler::print_insn, if we catch
- an error then we first print any pending output in the instruction
- buffer, before rethrowing the exception. As a result, even if an
- exception is thrown we still print any pending disassembler output to
- the screen; in the above case the helpful message will now be shown.
-
- Before my patch we might expect to see this output:
-
- (gdb) disassemble 0x0,+4
- Dump of assembler code from 0x0 to 0x4:
- 0x0000000000000000: unknown disassembler error (error = -1)
- (gdb)
-
- But now we see this:
-
- (gdb) disassemble 0x0,+4
- Dump of assembler code from 0x0 to 0x4:
- 0x0000000000000000: 64-bit address is disabled
- unknown disassembler error (error = -1)
-
- If the disassembler returns -1 without printing a helpful message then
- we would still expect a change in output, something like:
-
- (gdb) disassemble 0x0,+4
- Dump of assembler code from 0x0 to 0x4:
- 0x0000000000000000:
- unknown disassembler error (error = -1)
-
- Which I think is still acceptable, though at this point I think a
- strong case can be made that this is a disassembler bug (not printing
- anything, but still returning -1).
-
- Notice however, that the error message is always printed on a new line
- now. This is also true for the memory error case, where before we
- might see this:
-
- (gdb) disassemble 0x0,+4
- Dump of assembler code from 0x0 to 0x4:
- 0x00000000: Cannot access memory at address 0x0
-
- We now get this:
-
- (gdb) disassemble 0x0,+4
- Dump of assembler code from 0x0 to 0x4:
- 0x00000000:
- Cannot access memory at address 0x0
-
- For me, I'm happy to accept this change, having the error on a line by
- itself, rather than just appended to the end of the previous line,
- seems like an improvement, but I'm aware others might feel
- differently, so I'd appreciate any feedback.

- ppc: recognize all program traps
- Permanent program breakpoints (ones inserted into the code) other than
- the one GDB uses for POWER (0x7fe00008) did not result in stop but
- caused GDB to loop infinitely.
-
- This was because GDB did not recognize trap instructions other than
- "trap". For example, "tw 12, 4, 4" was not be recognized, causing GDB
- to loop forever.
-
- This commit fixes this by providing POWER specific hook

- gdb: make struct linespect contain vectors, not pointers to vectors
- struct linespec contains pointers to vectors, instead of containing

- (which contains a struct linespec field) was not C++-ified yet. But it
- seems easy to change the pointers to vectors to just vectors today.
- This simplifies the code, we don't need to manually allocate and delete
- the vectors and there's no pointer that can be NULL.
-
- As far as I understand, there was not meaningful distinction between a
- NULL pointer to vector and an empty vector. So all NULL checks are
- changed for !empty checks.

- [gdb/testsuite] Fix options arg handling in compile_jit_elf_main_as_so
- In commit 80ad340c902 ("[gdb/testsuite] use -Ttext-segment for jit-elf tests")
- the following change was made:
- ...
- proc compile_jit_elf_main_as_so {main_solib_srcfile main_solib_binfile options} {
- - set options [concat $options debug]
- + global jit_load_address jit_load_increment

- + set options [list \
- + additional_flags="-DMAIN=jit_dl_main" \
- + additional_flags=-DLOAD_ADDRESS=$jit_load_address \
- + additional_flags=-DLOAD_INCREMENT=$jit_load_increment \
- + debug]
- ...
-
- Before the change, the options argument was used, but after the change not
- anymore.
-
- Fix this by reverting back to using "set options [concat $options ...]".
-
- Fixing this gets us twice the -DMAIN=jit_dl_main bit, once from a caller, and
- once from compile_jit_elf_main_as_so. Fix this by removing the bit from
- compile_jit_elf_main_as_so, which makes the code similar to compile_jit_main.

- ...
-
- When compiled to a non-PIE exec:
- ...
- $ gcc -m32 test.c
- ...
- the call sequence looks like:
- ...
- 8048447: 83 ec 0c sub $0xc,%esp
- 804844a: 6a 0a push $0xa
- 804844c: e8 bf fe ff ff call 8048310 <malloc@plt>

- ...
-
- Likewise, when compiled as a PIE:
- ...
- $ gcc -m32 -fPIE -pie test.c
- ...
- we have this call sequence (with %ebx setup to point to the .got.plt):
- ...
- 0000055d <main>:
- 579: 83 ec 0c sub $0xc,%esp
- 57c: 6a 0a push $0xa
- 57e: 89 c3 mov %eax,%ebx
- 580: e8 6b fe ff ff call 3f0 <malloc@plt>
- ...
- which calls to:
- ...
- 000003f0 <malloc@plt>:
- 3f0: ff a3 0c 00 00 00 jmp *0xc(%ebx)
- 3f6: 68 00 00 00 00 push $0x0
- 3fb: e9 e0 ff ff ff jmp 3e0 <.plt>
- ...
- where the insn at 0x3f0 initially jumps to following address 0x3f6, read from
- the .got.plt at offset 0xc:
- ...
- 2000 f41e0000 00000000 00000000 f6030000 ................
- 2010 06040000 ....
- ...
-
- When instead doing an inferior call to malloc (with nosharedlib to force
- malloc to resolve to malloc@plt rather than the functions in ld.so or libc.so)
- with the non-PIE exec, we have the expected:
- ...
- $ gdb -q -batch a.out -ex start -ex nosharedlib -ex "p /x (void *)malloc (10)"
- Temporary breakpoint 1 at 0x8048444
-
- Temporary breakpoint 1, 0x08048444 in main ()
- $1 = 0x804b160
- ...
-
- But with the PIE exec, we run into:
- ...
- $ gdb -q -batch a.out -ex start -ex nosharedlib -ex "p /x (void *)malloc (10)"
- Temporary breakpoint 1 at 0x56c
-
- Temporary breakpoint 1, 0x5655556c in main ()
-
- Program received signal SIGSEGV, Segmentation fault.
- 0x565553f0 in malloc@plt ()
- ...
-
- The segfault happens because:
- - the inferior call mechanism doesn't setup %ebx
- - %ebx instead is 0
- - the jump to "*0xc(%ebx)" reads from memory at 0xc
-
- Fix this by setting up %ebx properly in i386_thiscall_push_dummy_call.

- [gdb/testsuite] Use precise align in gdb.arch/i386-{avx,sse}.exp
- Test-cases gdb.arch/i386-{avx,sse}.exp use assembly instructions that require
- the memory operands to be aligned to a certain boundary, and the test-cases
- use C11's _Alignas to make that happen.
-
- The draw-back of using _Alignas is that while it does enforce a minimum
- alignment, the actual alignment may be bigger, which makes the following
- scenario possible:
- - copy say, gdb.arch/i386-avx.c as basis for a new test-case
- - run the test-case and observe a PASS
- - commit the new test-case in the supposition that the test-case is correct
- and well-tested
- - run later into a failure on a different test setup (which may be a setup
- where reproduction and investigation is more difficult and time-consuming),
- and find out that the specified alignment was incorrect and should have been
- updated to say, 64 bytes. The initial PASS occurred only because the actual
- alignment happened to be greater than required.
-
- The idea of having precise alignment as a means of having more predictable
- execution which allows flushing out bugs earlier, has been filed as PR
- gcc/103095.
-
- Add a new file lib/precise-aligned-alloc.c with functions
- precise_aligned_alloc and precise_aligned_dup, to support precise alignment.
-
- Use precise_aligned_dup in aforementioned test-cases to:
- - verify that the specified alignment is indeed sufficient, rather
- than too little but accidentally over-aligned.
- - prevent the same type of problems in any new test-cases based on these
-
- Tested on x86_64-linux, with both gcc and clang.

- [GOLD] PowerPC64 inline plt sequences
- The fixes gold failures to handle inline PLT sequences properly.
- PowerPC gold was always turning these back into direct calls due to
- gsym->use_plt_offset() returning false. This is fixed for dynamic
- linking by correcting get_reference_flags, and for static linking by
- overriding use_plt_offset() in relocate(). The rest of the patch
- revolves around needing to create PLT entries for inline PLT calls
- when statically linking (for gcc -mlongcall). The lplt section
- handled that for local symbols, now it does globals too.

- ASan made me notice a memory leak, where the memory tied to the file
- handle name string wasn't freed. When register a file handler with an

- ended up creating a new std::string object and overwriting the

- delete, and making file_handler::name not a pointer.

- gdb: make extract_integer take an array_view
- I think it would make sense for extract_integer, extract_signed_integer
- and extract_unsigned_integer to take an array_view. This way, when we
- extract an integer, we can validate that we don't overflow the buffer
- passed by the caller (e.g. ask to extract a 4-byte integer but pass a
- 2-byte buffer).
-
- - Change extract_integer to take an array_view
- - Add overloads of extract_signed_integer and extract_unsigned_integer
- that take array_views. Keep the existing versions so we don't
- need to change all callers, but make them call the array_view
- versions.
-
- This shortens some places like:
-
- result = extract_unsigned_integer (value_contents (result_val).data (),
- TYPE_LENGTH (value_type (result_val)),
- byte_order);
-
- into
-
- result = extract_unsigned_integer (value_contents (result_val), byte_order);
-
- value_contents returns an array view that is of length
- `TYPE_LENGTH (value_type (result_val))` already, so the length is
- implicitly communicated through the array view.

-
- gdbsupport: add array_view copy function
- An assertion was recently added to array_view::operator[] to ensure we
- don't do out of bounds accesses. However, when the array_view is copied
- to or from using memcpy, it bypasses that safety.
-
- To address this, add a `copy` free function that copies data from an
- array view to another, ensuring that the destination and source array
- views have the same size. When copying to or from parts of an
- array_view, we are expected to use gdb::array_view::slice, which does
- its own bounds check. With all that, any copy operation that goes out
- of bounds should be caught by an assertion at runtime.
-
- copy is implemented using std::copy and std::copy_backward, which, at
- least on libstdc++, appears to pick memmove when copying trivial data.
- So in the end there shouldn't be much difference vs using a bare memcpy,
- as we do right now. When copying non-trivial data, std::copy and
- std::copy_backward assigns each element in a loop.
-
- To properly support overlapping ranges, we must use std::copy or
- std::copy_backward, depending on whether the destination is before the
- source or vice-versa. std::copy and std::copy_backward don't support
- copying exactly overlapping ranges (where the source range is equal to
- the destination range). But in this case, no copy is needed anyway, so
- we do nothing.
-
- The order of parameters of the new copy function is based on std::copy
- and std::copy_backward, where the source comes before the destination.
-
- Change a few randomly selected spots to use the new function, to show
- how it can be used.
-
- Add a test for the new function, testing both with arrays of a trivial
- type (int) and of a non-trivial type (foo). Test non-overlapping
- ranges as well as three kinds of overlapping ranges: source before dest,
- dest before source, and dest == source.

- While playing with some code creating target_waitstatus objects, I was

- Make the setters return the "this" object as a reference, such that it's

-
- included a large amount of binary data in the command sent to GDB. As
- this test didn't have a real test name the binary data was included in
- the gdb.sum file. The contents of the binary data could change
- between different runs of GDB, and this makes comparing results

- gdb/remote: fix use after free bug
- This commit:
-
- commit 288712bbaca36bff6578bc839ebcdc3707662f81
- Date: Mon Nov 22 15:16:27 2021 +0000
-
- gdb/remote: use scoped_restore to control starting_up flag
-
- introduced a use after free bug. The scoped restore added in the
- above commit resets a flag within a remote_target's remote_state
- object.
-
- However, in some situations, the remote_target can be unpushed before
- the error is thrown. If the only reference to the target is the one
- in the target stack, then unpushing the target will cause the
- remote_target to be deleted, which, in turn, will delete the
- remote_state object. The scoped restore will then try to reset the
- flag within a deleted object.
-
- This problem was caught in the gdb.server/server-connect.exp test,
- which, when run with the address sanitizer enabled, highlights the
- write after free bug described above.
-
- This commit resolves this issue by adding a new class specifically for
- the purpose of managing the starting_up flag. As well as setting, and
- then clearing the starting_up flag, this new class increments, and
- then decrements the reference count on the remote_target object. This
- prevents the remote_target from being deleted until after the flag has
- been reset.
-
- The gdb.server/server-connect.exp now runs cleanly with the address
- sanitizer enabled.

- libctf: workaround automake bug with conditional info pages
- It looks like automake makes assumptions about its ability to build info
- pages based on the GNU standard behavior of shipping info pages with the
- distributions. So even though the info pages were conditionalized, and
- automake disabled some of the targets, it was still creeping in by way
- of unconditional INFO_DEPS settings.
-
- We can workaround this by adding a stub target for the info page when
- building info pages are disabled. This tricks automake into disabling
- its own extended generation target. I'll follow up with the automake
- folks to see what they think.

- [gdb/tdep] Fix avx512 -m32 support in gdbserver
- PR27257 reports a problem that can be reproduced as follows:
- - use x86_64 machine with avx512 support
- - compile a hello world with -m32 to a.out
- - start a gdbserver session with a.out
- - use gdb to connect to the gdbserver session
-
- This makes us run into:
- ...
- Listening on port 2346
- Remote debugging from host ::1, port 34940
- src/gdbserver/regcache.cc:257: \
- A problem internal to GDBserver has been detected.
- Unknown register zmm16h requested
- ...
-
- The problem is that i387_xsave_to_cache in gdbserver/i387-fp.cc can't find a
- register zmm16h in the register cache.
-
- To understand how this happens, first some background.
-
- SSE has 16 128-bit wide xmm registers.
-
- AVX extends the SSE registers set as follows:
- - it extends the 16 existing 128-bit wide xmm registers to 256-bit wide ymm
- registers.
-
- AVX512 extends the AVX register set as follows:
- - it extends the 16 existing 256-bit wide ymm registers to 512-bit wide zmm
- registers.
- - it adds 16 additional 512-bit wide zmm registers (with corresponding ymm and
- xmm subregisters added as well)
-
- However, in 32-bit mode, there are only 8 xmm/ymm/zmm registers.
-
- The problem we're running into is that gdbserver/i387-fp.cc uses these
- constants to describe the size of the register file:
- ...
- static const int num_avx512_zmmh_low_registers = 16;
- static const int num_avx512_zmmh_high_registers = 16;
- static const int num_avx512_ymmh_registers = 16;
- static const int num_avx512_xmm_registers = 16;
- ...
- which are all incorrect for the 32-bit case.
-
- Fix this by replacing the constants with variables that have the appropriate
- values in 64-bit and 32-bit mode.
-
- Tested on x86_64-linux with native and unix/-m32.

- gdb/testsuite: update tests looking for "DWARF 2" debug format
- Commit ab557072b8ec ("gdb: use actual DWARF version in compunit's
- debugformat field") changes the debug format string in "info source" to
- show the actual DWARF version, rather than always show "DWARF 2".
-
- However, it failed to consider that some tests checked for the "DWARF 2"
- string to see if the test program is compiled with DWARF debug
- information. Since everything is compiled with DWARF 4 or 5 nowadays,
- that changed the behavior of those tests. Notably, it prevent the
- tests using skip_inline_var_tests to run.
-
- Grep through the testsuite for "DWARF 2" and change all occurrences I
- could find to use "DWARF [0-9]" instead (that string is passed to TCL's
- string match).

- (PPC64) fix handling of fixed-point values when using "return" command
- In the gdb.ada/fixed_points_function.exp testcase, we have the following
- Ada code...
-
- type FP1_Type is delta 0.1 range -1.0 .. +1.0; -- Ordinary
- function Call_FP1 (F : FP1_Type) return FP1_Type is
- begin
- FP1_Arg := F;
- return FP1_Arg;
- end Call_FP1;
-
- ... used as follow:
-
- F1 : FP1_Type := 1.0;
- F1 := Call_FP1 (F1);
-
- The testcase, among other things, verifies that "return" works
- properly as follow:
-
- | (gdb) return 1.0
- | Make pck.call_fp1 return now? (y or n) y
- | [...]
- | 9 F1 := Call_FP1 (F1);
- | (gdb) next
- | (gdb) print f1
- | $1 = 0.0625
-
- The output of the last command shows that we returned the wrong
- value. The value printed gives a clue about the problem, since
- it is 1/16th of the value we expected, where 1/16 is FP1_Type's
- scaling factor.
-
- The problem, here, comes from the fact that the function
- handling return values for base types (ppc64_sysv_abi_return_value_base)
- writes the return value using unpack_long which, upon seeing that
- the value being unpacked is a fixed point type, applies the scaling
- factor, to get the integer-representation of our fixed-point value
- (similar to what it does with floats, for instance).
-
- So, the fix consists in teaching ppc64_sysv_abi_return_value_base
- about fixed-point types, and to avoid the unwanted application
- of the scaling factor.
-
- Note that the "finish" function, on the other hand, does not
- suffer from this issue, simply becaue the value returned by
- the function is read from register without the use of a type,
- thus avoiding an unwanted application of a scaling factor.
-
- No test added, as this change is already tested by
- gdb.ada/fixed_points_function.exp.

- (RISCV) fix handling of fixed-point type return values
- This commit adds support for TYPE_CODE_FIXED_POINT types for
- "finish" and "return" commands.
-
- Consider the following Ada code...
-
- type FP1_Type is delta 0.1 range -1.0 .. +1.0; -- Ordinary
- function Call_FP1 (F : FP1_Type) return FP1_Type is
- begin
- FP1_Arg := F;
- return FP1_Arg;
- end Call_FP1;
-
- ... used as follow:
-
- F1 : FP1_Type := 1.0;
- F1 := Call_FP1 (F1);
-
- "finish" currently behaves as follow:
-
- | (gdb) finish
- | [...]
- | Value returned is $1 = 0
-
- We expect the returned value to be "1".
-
- Similarly, "return" makes the function return the wrong value:
-
- | (gdb) return 1.0
- | Make pck.call_fp1 return now? (y or n) y
- | [...]
- | 9 F1 := Call_FP1 (F1);
- | (gdb) next
- | (gdb) print f1
- | $1 = 0.0625
-
- (we expect it to print "1" instead).
-
- This problem comes from the handling of integral return values
- when the return value is actually fixed point type. Our type
- here is actually a range of a fixed point type, but the same
- principles should also apply to pure fixed-point types. For
- the record, here is what the debugging info looks like:
-
- <1><238>: Abbrev Number: 2 (DW_TAG_subrange_type)
- <239> DW_AT_lower_bound : -16
- <23a> DW_AT_upper_bound : 16
- <23b> DW_AT_name : pck__fp1_type
- <23f> DW_AT_type : <0x248>
-
- <1><248>: Abbrev Number: 4 (DW_TAG_base_type)
- <249> DW_AT_byte_size : 1
- <24a> DW_AT_encoding : 13 (signed_fixed)
- <24b> DW_AT_binary_scale: -4
- <24c> DW_AT_name : pck__Tfp1_typeB
- <250> DW_AT_artificial : 1
-
- ... where the scaling factor is 1/16.
-
- Looking at the "finish" command, what happens is that riscv_arg_location
- determines that our return value should be returned by parameter using
- an integral convention (via builtin type long). And then,
- riscv_return_value uses a cast to that builtin type long to
- store the value of into a buffer with the right register size.
- This doesn't work in our case, because the underlying value
- returned by the function is unscaled, which means it is 16,
- and thus the cast is like doing:
-
- arg_val = (FP1_Type) 16
-
- ... In other words, it is trying to create an FP1_Type enty whose
- value is 16. Applying the scaling factor, that's 256, and because
- the size of FP1_Type is 1 byte, we overflow and thus it ends up
- being zero.
-
- The same happen with the "return" function, but the other way around.
-
- The fix consists in handling fixed-point types separately from
- integral types.

- (ARM/fixed-point) wrong value shown by "finish" command:
- Consider the following Ada code:
-
- type FP1_Type is delta 0.1 range -1.0 .. +1.0; -- Ordinary
- FP1_Arg : FP1_Type := 0.0;
-
- function Call_FP1 (F : FP1_Type) return FP1_Type is
- begin
- FP1_Arg := F;
- return FP1_Arg;
- end Call_FP1;
-
- After having stopped inside function Call_FP1 as follow:
-
- Breakpoint 1, pck.call_fp1 (f=1) at /[...]/pck.adb:5
- 5 FP1_Arg := F;
-
- Returning from that function call using "finish" should show
- that the function return "1.0" (the same value as was passed
- as an argument). However, this is not the case:
-
- (gdb) finish
- Run till exit from #0 pck.call_fp1 (f=1)
- [...]
- 9 F1 := Call_FP1 (F1);
- Value returned is $1 = 0
-
- This patch enhances the extraction of the return value to know about
- fixed point types.

-
- (Ada/AArch64) fix fixed point argument passing in inferior funcall
- Consider the following code:
-
- type FP1_Type is delta 0.1 range -1.0 .. +1.0; -- Ordinary
-
- function Call_FP1 (F : FP1_Type) return FP1_Type is
- begin
- return F;
- end Call_FP1;
-
- When the default in GCC is to generate proper DWARF info for fixed point
- types, then in gdb, printing the result of a call to call_fp1 with a
- decimal parameter leads to:
-
- (gdb) p call_fp1(0.5)
- $1 = 0
-
- The displayed value is wrong, and we actually expected:
-
- (gdb) p call_fp1(0.5)
- $1 = 0.5
-
- What happened is that our fixed point type parameter got promoted to a
- 32bit integer because we detected that the length of that object was less
- than 4 bytes. The compiler does not perform this promotion and therefore
- GDB should not either.
-
- This patch fixes the behavior described above.

- aarch64: Add maximum immediate value to aarch64_sys_reg
- The immediate form of MSR has a 4-bit immediate field (in CRm).
- However, many forms of MSR require a smaller immediate. These cases
- are identified by value in operand_general_constraint_met_p,
- but they're now the common case rather than the exception.
-
- This patch therefore adds the maximum value to the sys_reg
- description and gets the range from there. It also enforces
- the minimum of 0, which avoids a situation in which:
-
- msr dit, #2
-
- would give the expected:
-
- Error: immediate value out of range 0 to 1
-
- whereas:
-
- msr dit, #-1
-
- would give:
-
- Error: immediate value out of range 0 to 15
-
- (from the later UIMM4 checking).
-
- Also:
-
- - we were reporting the first error above against the wrong operand
- - TCO takes a single-bit immediate, but we previously allowed
- all 16 values.

- gdb, include: replace pragmas with DIAGNOSTIC macros, fix build with g++ 4.8
- When introducing this code, I forgot that we had some macros for this.
- Replace some "manual" pragma diagnostic with some DIAGNOSTIC_* macros,
- provided by include/diagnostics.h.
-
- In diagnostics.h:
-
- - Add DIAGNOSTIC_ERROR, to enable a diagnostic at error level.
- - Add DIAGNOSTIC_ERROR_SWITCH, to enable -Wswitch at error level, for
- both gcc and clang.
-
- Additionally, using DIAGNOSTIC_PUSH, DIAGNOSTIC_ERROR_SWITCH and
- DIAGNOSTIC_POP seems to misbehave with g++ 4.8, where we see these
- errors:
-
- CXX ada-tasks.o
- /home/smarchi/src/binutils-gdb/gdb/ada-tasks.c: In function void read_known_tasks():
- /home/smarchi/src/binutils-gdb/gdb/ada-tasks.c:998:10: error: enumeration value ADA_TASKS_UNKNOWN not handled in switch [-Werror=switch]
- switch (data->known_tasks_kind)
- ^
-
- Because of the POP, the diagnostic should go back to being disabled,
- since it was disabled in the beginning, but that's not what we see
- here. Versions of GCC >= 5 compile correctly.
-
- Work around this by making DIAGNOSTIC_ERROR_SWITCH a no-op for GCC < 5.
-
- Note that this code (already as it exists in master today) enables
- -Wswitch at the error level even if --disable-werror is passed. It
- shouldn't be a problem, as it's not like a new enumerator will appear
- out of nowhere and cause a build error if building with future
- compilers. Still, for correctness, we would ideally want to ask the
- compiler to enable -Wswitch at its default level (as if the user had
- passed -Wswitch on the command-line). There doesn't seem to be a way to
- do this.

- gdb/remote: use scoped_restore to control starting_up flag
- This commit makes use of a scoped_restore object to control the
- remote_state::starting_up flag within the remote_target::start_remote
- method.
-
- Ideally I would have liked to create the scoped_restore inside
- start_remote and just leave the restore in place until the end of the
- scope, however, I'm worried that doing this would change the behaviour
- of GDB. Specifically, in start_remote, the following code is executed
- once the starting_up flag has been restored to its previous value:
-
- if (breakpoints_should_be_inserted_now ())
- insert_breakpoints ();
-
- I think (but am not 100% sure) that calling install_breakpoints could
- end up back inside remote_target::can_download_tracepoint, which does
- check the value of remote_state::starting_up. And so, I'm concerned
- that leaving the scoped_restore in place until the end of start_remote
- will cause a possible change in behaviour.
-
- To avoid this, and to leave things as close to the current behaviour
- as possible, I've split remote_target::start_remote into two, there's
- the main function body which moves into remote_target::start_remote_1,
- this function uses the scoped_restore to change the ::starting_up
- flag, then there's the old remote_target::start_remote, which now just
- calls ::start_remote_1, and then does the insert_breakpoints call.
-
- There should be no user visible changes after this commit, unless
- there's a situation where the ::starting_up flag could previously have
- been left set, if this was the case, then this situation should no
- longer be possible.

- aarch64: Check for register aliases before mnemonics
- Previously we would not accept:
-
- A .req B
-
- if A happened to be the name of an instruction. Adding new
- instructions could therefore invalidate existing register aliases.
-
- I noticed this with a test that used "zero" as a register alias
- for "xzr", where "zero" is now also the name of an SME instruction.
- I don't have any evidence that "real" code is doing this, but it
- seems at least plausible.
-
- This patch switches things so that we check for register aliases
- first. It might slow down parsing slightly, but the difference
- is unlikely to be noticeable.
-
- Things like:
-
- b .req + 0
-
- still work, since create_register_alias checks for " .req ",
- and with the input scrubber, we'll only keep whitespace after
- .req if it's followed by another name. If there's some valid
- expression that I haven't thought about that is scrubbed to
- " .req ", users could avoid the ambiguity by wrapping .req
- in parentheses.
-
- The new test for invalid aliases already passed. I just wanted
- something to exercise the !dot condition.
-
- I can't find a way of exercising the (existing) p == base condition,
- but I'm not brave enough to say that it can never happen. If it does
- happen, get_mnemonic_name would return an empty string.

- gdb/python: don't use the 'p' format for parsing args
- When running the gdb.python/py-arch.exp tests on a GDB built
- against Python 2 I ran into some errors. The problem is that this
- test script exercises the gdb.Architecture.integer_type method, and
- this method uses 'p' as an argument format specifier in a call to
- gdb_PyArg_ParseTupleAndKeywords.
-
- Unfortunately this specified was only added in Python 3.3, so will
- cause an error for earlier versions of Python.
-
- This commit switches to use the 'O' specifier to collect a PyObject,
- and then uses PyObject_IsTrue to convert the object to a boolean.
-
- An earlier version of this patch incorrectly switched from using 'p'
- to use 'i', however, it was pointed out during review that this would
- cause some changes in behaviour, for example both of these will work
- with 'p', but not with 'i':
-
- gdb.selected_inferior().architecture().integer_type(32, None)
- gdb.selected_inferior().architecture().integer_type(32, "foo")
-
- The new approach of using 'O' works fine with these cases. I've added
- some new tests to cover both of the above.
-
- There should be no user visible changes after this commit.

- gdb: fix disassembler regressions for 32-bit arm
- After this commit:
-
- commit 76b43c9b5c2b275cbf4f927bfc25984410cb5dd5
- Date: Tue Oct 5 15:10:12 2021 +0100
-
- gdb: improve error reporting from the disassembler
-
- We started seeing FAILs in the gdb.base/all-architectures*.exp tests,
- when running on a 32-bit ARM target, though I suspect running on any
- target that compiles such that bfd_vma is 32-bits would also trigger
- the failures.
-
- The problem is that the test is expected GDB's disassembler to print
- an error like this:
-
- Cannot access memory at address 0x0
-
- However, after the above commit we see an error like:
-
- unknown disassembler error (error = -1)
-
- The reason for this is this code in opcodes/i386-dis.c (in the
- print_insn function):
-
- if (address_mode == mode_64bit && sizeof (bfd_vma) < 8)
- {
- (*info->fprintf_func) (info->stream,
- _("64-bit address is disabled"));
- return -1;
- }
-
- This code effectively disallows us from ever disassembling 64-bit x86
- code if we compiled GDB with a 32-bit bfd_vma. Notice we return
- -1 (indicating a failure to disassemble), but never call the
- memory_error_func callback.
-
- Prior to the above commit GDB, when it received the -1 return value
- would assume that a memory error had occurred and just print whatever
- value happened to be in the memory error address variable, the default
- value of 0 just happened to be fine because the test had asked GDB to
- do this 'disassemble 0x0,+4'.
-
- If we instead change the test to do 'disassemble 0x100,+4' then GDB
- would (previously) have still reported:
-
- Cannot access memory at address 0x0
-
- which makes far less sense.
-
- In this commit I propose to fix this issue by changing the test to
- accept either the "Cannot access memory ..." string, or the newer
- "unknown disassembler error ..." string. With this change done the
- test now passes.
-
- However, there is one weakness with this strategy; if GDB broke such
- that we _always_ reported "unknown disassembler error ..." we would
- never notice. This clearly would be bad. To avoid this issue I have
- adjusted the all-architectures*.exp tests so that, when we disassemble
- for the default architecture (the one selected by "auto") we _only_
- expect to get the "Cannot access memory ..." error string.
-
- [ Note: In an ideal world we should be able to disassemble any
- architecture at all times. There's no reason why the 64-bit x86
- disassembler requires a 64-bit bfd_vma, other than the code happens
- to be written that way. We could rewrite the disassemble to not
- have this requirement, but, I don't plan to do that any time soon. ]
-
- Further, I have changed the all-architectures*.exp test so that we now
- disassemble at address 0x100, this should avoid us being able to pass
- by printing a default address of 0x0. I did originally change the
- address we disassembled at to 0x4, however, some architectures,
- e.g. ia64, have a default instruction alignment that is greater than
- 4, so would still round down to 0x0. I could have just picked 0x8 as
- an address, but I figured that 0x100 was likely to satisfy most
- architectures alignment requirements.

- gdb/python: add gdb.RemoteTargetConnection.send_packet
- This commits adds a new sub-class of gdb.TargetConnection,
- gdb.RemoteTargetConnection. This sub-class is created for all
- 'remote' and 'extended-remote' targets.
-
- This new sub-class has one additional method over its base class,
- 'send_packet'. This new method is equivalent to the 'maint
- packet' CLI command, it allows a custom packet to be sent to a remote
- target.
-
- The outgoing packet can either be a bytes object, or a Unicode string,
- so long as the Unicode string contains only ASCII characters.
-
- The result of calling RemoteTargetConnection.send_packet is a bytes
- object containing the reply that came from the remote.
-
-2021-11-30 Andrew Burgess <aburgess@redhat.com>
-
- gdb: make packet_command function available outside remote.c
- In a later commit I will add a Python API to access the 'maint packet'
- functionality, that is, sending a user specified packet to the target.
-
- To make implementing this easier, this commit refactors how this
- command is currently implemented so that the packet_command function
- is now global.
-
- The new global send_remote_packet function takes an object that is an
- implementation of an abstract interface. Two functions within this
- interface are then called, one just before a packet is sent to the
- remote target, and one when the reply has been received from the
- remote target. Using an interface object in this way allows (1) for
- the error checking to be done before the first callback is made, this
- means we only print out what packet it being sent once we know we are
- going to actually send it, and (2) we don't need to make a copy of the
- reply if all we want to do is print it.
-
- One user visible changes after this commit are the error
- messages, which I've changed to be less 'maint packet' command
- focused, this will make them (I hope) better for when
- send_remote_packet can be called from Python code.
-
- So: "command can only be used with remote target"
- Becomes: "packets can only be sent to a remote target"
-
- And: "remote-packet command requires packet text as argument"
- Becomes: "a remote packet must not be empty"
-
- Additionally, in this commit, I've added support for packet replies
- that contain binary data. Before this commit, the code that printed
- the reply treated the reply as a C string, it assumed that the string
- only contained printable characters, and had a null character only at
- the end.
-
- One way to show the problem with this is if we try to read the auxv
- data from a remote target, the auxv data is binary, so, before this
- commit:
-
- (gdb) target remote :54321
- ...
- (gdb) maint packet qXfer:auxv:read::0,1000
- sending: "qXfer:auxv:read::0,1000"
- received: "l!"
- (gdb)
-
- And after this commit:
-
- (gdb) target remote :54321
- ...
- (gdb) maint packet qXfer:auxv:read::0,1000
- sending: "qXfer:auxv:read::0,1000"
- received: "l!\x00\x00\x00\x00\x00\x00\x00\x00\xf0\xfc\xf7\xff\x7f\x00\x00\x10\x00\x00\x00\x00\x00\x00\x00\xff\xf>
- (gdb)
-
- The binary contents of the reply are now printed as escaped hex.

- gdb/python: introduce gdb.TargetConnection object type
- This commit adds a new object type gdb.TargetConnection. This new
- type represents a connection within GDB (a connection as displayed by
- 'info connections').
-
- There's three ways to find a gdb.TargetConnection, there's a new
- 'gdb.connections()' function, which returns a list of all currently
- active connections.
-
- Or you can read the new 'connection' property on the gdb.Inferior
- object type, this contains the connection for that inferior (or None
- if the inferior has no connection, for example, it is exited).
-
- Finally, there's a new gdb.events.connection_removed event registry,
- this emits a new gdb.ConnectionEvent whenever a connection is removed
- from GDB (this can happen when all inferiors using a connection exit,
- though this is not always the case, depending on the connection type).
- The gdb.ConnectionEvent has a 'connection' property, which is the
- gdb.TargetConnection being removed from GDB.
-
- The gdb.TargetConnection has an 'is_valid()' method. A connection
- object becomes invalid when the underlying connection is removed from
- GDB (as discussed above, this might be when all inferiors using a
- connection exit, or it might be when the user explicitly replaces a
- connection in GDB by issuing another 'target' command).
-
- The gdb.TargetConnection has the following read-only properties:
-
- 'num': The number for this connection,
-
- 'type': e.g. 'native', 'remote', 'sim', etc
-
- 'description': The longer description as seen in the 'info
- connections' command output.
-
- 'details': A string or None. Extra details for the connection, for
- example, a remote connection's details might be
- 'hostname:port'.

- RISC-V: The vtype immediate with more than the defined 8 bits are preserved.
- According the rvv spec,
- https://github.com/riscv/riscv-v-spec/blob/master/vtype-format.adoc
-
- The bits of vtype immediate from 8 to (xlen - 1) should be reserved.
- Therefore, we should also dump the vtype immediate as numbers, when
- they are set over 8-bits. I think this is a bug that we used to support
- vediv extension and use the bit 8 and 9 of vtype, but forgot to update
- the behavior when removing the vediv.
-
- Consider the testcases,
-
- vsetvli a0, a1, 0x700 # the reserved bit 10, 9 and 8 are used.
- vsetvli a0, a1, 0x400 # the reserved bit 10 is used.
- vsetvli a0, a1, 0x300 # the reserved bit 9 and 8 are used.
- vsetvli a0, a1, 0x100 # the reserved bit 8 is used.
- vsetivli a0, 0xb, 0x300 # the reserved bit 9 and 8 are used.
- vsetivli a0, 0xb, 0x100 # the reserved bit 8 is used.
-
- The original objdump shows the following result,
-
- 0000000000000000 <.text>:
- 0: 7005f557 vsetvli a0,a1,1792

- RISC-V: Dump vset[i]vli immediate as numbers once vsew or vlmul is reserved.

- vsetivli a0, 0xb, 0x4 # unrecognized vlmul

-
- For the current dis-assembler, we get the result,

-
- The vsew e128 and vlmul (null) are preserved according to the spec,

- the unrecognized csr as csr numbers directly, we should also dump
- the whole vset[i]vli immediates as numbers, once the vsew or vlmul

- Allow DW_ATE_UTF for Rust characters
- The Rust compiler plans to change the encoding of a Rust 'char' type
- to use DW_ATE_UTF. You can see the discussion here:
-
- https://github.com/rust-lang/rust/pull/89887
-
- However, this fails in gdb. I looked into this, and it turns out that
- the handling of DW_ATE_UTF is currently fairly specific to C++. In
- particular, the code here assumes the C++ type names, and it creates
- an integer type.
-
- This comes from commit 53e710acd ("GDB thinks char16_t and char32_t
- are signed in C++"). The message says:
-
- Both places need fixing. But since I couldn't tell why dwarf2read.c
- needs to create a new type, I've made it use the per-arch built-in
- types instead, so that the types are only created once per arch
- instead of once per objfile. That seems to work fine.
-
- ... which is fine, but it seems to me that it's also correct to make a
- new character type; and this approach is better because it preserves
- the type name as well. This does use more memory, but first we
- shouldn't be too concerned about the memory use of types coming from
- debuginfo; and second, if we are, we should implement type interning
- anyway.
-
- Changing this code to use a character type revealed a couple of
- oddities in the C/C++ handling of TYPE_CODE_CHAR. This patch fixes
- these as well.
-
- I filed PR rust/28637 for this issue, so that this patch can be
- backported to the gdb 11 branch.

- sim: testsuite: drop most specific istarget checks
- We'll rely on the toolchain probing to determine whether each arch's
- tests can be run rather the current configure target. This allows
- testing all of the ports in a multitarget configuration.
-
- For now, we don't reformat the files entirely to make it easier to

- like it's stable, we can flatten the code a bit by removing the if

- sim: testsuite: support parallel execution
- Break up the dejagnu logic so that we can parallelize the testsuite.
- This takes a page from gcc & gdb where each .exp is run in isolation
- instead of in serial.
-
- For most targets, this doesn't make much of a difference as they only
- have a single .exp. A few (like cris & frv) have multiple .exp though
- and will see a bit of a speed up.
-
- The real gain is when testing a multitarget build. This way we can
- run all the targets in parallel and cut the execution time a bit.
- On my system, it goes from ~155sec to ~100sec.
-
- We can gain further speedups by splitting up some of the larger .exp
- files into smaller groups. We'll do that in a followup though.

- sim: testsuite: setup per-port toolchain settings for multitarget build
- Gas does not support multitarget builds -- it still only supports

- manual flags to select the right output. This makes it impossible
- to run the complete testsuite in a multitarget build.
-
- To address this limitation, create a suite of FOR_TARGET variables
- so these can be set to precompiled as & ld programs. It requires
- a bit of setup ahead of time, but it's a one-time cost, and makes
- running the full testsuite at once much easier.

- sim: add checks to core headers to prevent incorrect common building
- Some of the core sim headers rely on the SIM_AC_OPTION_BITSIZE macro
- which can change the size of core types. Since these haven't been

- sim: testsuite: initial support for OS-specific tests
- We usually test against the newlib/libgloss environment, but for a
- few ports that also support Linux apps, we want to test that logic
- too. A lot of the C code is written such that it works with either
- newlib/libgloss or glibc/linux toolchains, but we have some tests
- that end up being Linux-specific. Cris has been using the target
- tuple as a rough proxy for this (where cris*-*-elf is assumed to be
- newlib/libgloss, and everything else is glibc/linux), but that is a
- bit too rough, and it doesn't work in a multitarget build.
-
- So lets create a few stub files that we can do compile tests with
- to detect the different setups, and then let tests declare which
- one they require (if they require any at all).

- sim: testsuite: rework sim_init usage
- The sim_init function was called by runtest for each test when --tool

- was still being called explicitly by config/default.exp. It's not clear
- why that explicit call ever existed since, in the past, it meant it was
- redundant.
-
- Lets drop the single sim_init call in config/default.exp and move it out
- to all our tests. This replicates the runtest behavior so we can setup
- variables on a per-test basis which allows us to recollapse the sim_path
- logic back. We'll also leverage this in the future for toolchain setup.

- gdb/python: make some global variables static
-
- building without Python was broken. The extension_language_python
- global was moved from being always defined, to only being defined when

- PR gdb/28480: Improve ambiguous member detection
- Basic ambiguity detection assumes that when 2 fields with the same name
- have the same byte offset, it must be an unambiguous request. This is not
- always correct. Consider the following code:
-
- class empty { };
-
- class A {
- public:
- [[no_unique_address]] empty e;
- };
-
- class B {
- public:
- int e;
- };
-
- class C: public A, public B { };
-
- if we tried to use c.e in code, the compiler would warn of an ambiguity,
- however, since A::e does not demand an unique address, it gets the same
- address (and thus byte offset) of the members, making A::e and B::e have the
- same address. however, "print c.e" would fail to report the ambiguity,
- and would instead print it as an empty class (first path found).
-
- The new code solves this by checking for other found_fields that have
- different m_struct_path.back() (final class that the member was found
- in), despite having the same byte offset.
-
- The testcase gdb.cp/ambiguous.exp was also changed to test for this
- behavior.

- coff-go32: consistent 16-byte section alignment
- Section alignment for coff-go32 is inconsistent - The '.text' and
- '.data' sections are 16-byte aligned, but named sections '.text.*' and
- '.data.*' are only 4-byte aligned. '.gnu.linkonce.r.*' is aligned to
- 16 bytes, yet '.rodata' and '.rodata.*' are aligned to 4 bytes. For
- '.bss' all input sections are only aligned to 4 bytes.
-
- This primarily can cause trouble when using SSE instructions, which
- require their memory operands to be aligned to 16-byte boundaries.
-
- This patch solves the issue simply by setting the section alignment
- to 16 bytes, for all code and data sections referenced in the default
- linker script.
-
- * coff-go32.c (COFF_SECTION_ALIGNMENT_ENTRIES): Use partial
- name match for .text, .data. Add entries for .const, .rodata,
- .bss, .gnu.linkonce.b.

- Re: AArch64: Add support for AArch64 EFI (efi-*-aarch64)
- Commit b69c9d41e8 edited bfd/Makefile.in rather than using automake,
- which meant a typo in Makefile.am was not discovered and other
- differences in Makefile.in are seen with a proper regeneration. One
- difference was lack of an empty line between the pe-aarch64igen.c rule
- and the following $(BFD32_LIBS) etc. dependency rule, in the
- regenerated file. Not that it matters for proper "make" behaviour,
- but it's nicer with a line between those rules. Moving the rule
- earlier seems to cure the missing empty line.
-

- gdb: rename source_styling_changed observer
- In a later commit I plan to add disassembler styling. In the same way
- that we have a source_styling_changed observer I would need to add a
- disassembler_styling_changed observer.
-
- However, currently, these observers would only be notified from
- cli-style.c:set_style_enabled, and observed in tui-winsource.c,
- tui_source_window::style_changed, as a result, having two observers
- seems unnecessary right now, so, in this commit, I plan to rename
- source_styling_changed to just styling_changed, then, in the later
- commit, when disassembler styling is added, I can use the same
- observer for both source styling, and disassembler styling.

- gdb: add assert in remote_target::wait relating to async being off
- While working on another patch I ended up in a situation where I had
- async mode disabled (with 'maint set target-async off'), but the async
- event token got marked anyway.
-
- In this situation GDB was continually calling into
- remote_target::wait, however, the async token would never become
- unmarked as the unmarking is guarded by target_is_async_p.
-
- We could just unconditionally unmark the token, but that would feel
- like just ignoring a bug, so, instead, lets assert that if
- !target_is_async_p, then the async token should not be marked.
-
- This assertion would have caught my earlier mistake.

- There should be no user visible changes with this commit.

- gdb: simplify remote_target::is_async_p
- This commit simplifies remote_target::is_async_p by removing the
- target_async_permitted check.
-
- In previous commits I have added additional assertions around the
- target_async_permitted flag into target.c, as a result we should now
- be confident that if target_can_async_p returns false, a target will
- never have async mode enabled. Given this, it should not be necessary
- to check target_async_permitted in remote_target::is_async_p, if this
- flag is false ::is_async_p should return false anyway. There is an
- assert to this effect in target_is_async_p.
-
- There should be no user visible change after this commit.

-
- gdb: add asserts in target.c for target_async_permitted
- The target_async_permitted flag allows a user to override whether a
- target can act in async mode or not. In previous commits I have moved
- the checking of this flag out of the various ::can_async_p methods and
- into the common target.c code.
-
- In this commit I will add some additional assertions into
- target_is_async_p and target_async. The rules these assertions are
- checking are:
-
- 1. A target that returns false for target_can_async_p should never
- become "async enabled", and so ::is_async_p should always return
- false. This is being checked in target_is_async_p.
-
- 2. GDB should never try to enable async mode for a target that
- returns false for target_can_async_p, this is checked in
- target_async.
-
- There are a few places where we call the ::is_async_p method directly,
- in these cases we will obviously not pass through the assert in
- target_is_async_p, however, there are also plenty of places where we
- do call target_is_async_p so if GDB starts to misbehave we should
- catch it quickly enough.
-
- There should be no user visible changes after this commit.

- gdb: hoist target_async_permitted checks into target.c
- This commit moves the target_async_permitted check out of each targets
- ::can_async_p method and into the target_can_async_p wrapper function.
-

- changed, which will hopefully catch any direct calls to these methods

-
- gdb: introduce a new overload of target_can_async_p
- There are a few places where we call the target_ops::can_async_p
- member function directly, instead of using the target_can_async_p
- wrapper.
-
- In some of these places this is because we need to ask before the
- target has been pushed, and in another location (in target.c) it seems
- unnecessary to go through the wrapper when we are already in target.c
- code.
-
- However, in the next commit I'd like to hoist some common checks out
- of target specific code into target.c. To achieve this, in this
- commit, I introduce a new overload of target_can_async_p which takes a
- target_ops pointer, and calls the ::can_async_p method directly. I
- then make use of the new overload where appropriate.

- There should be no user visible changes after this commit.

- [gdb/cli] Add "set logging enabled", deprecate "set logging on/off"
- Before commit 3b6acaee895 "Update more calls to add_prefix_cmd" we had the
- following output for "show logging file":
- ...
- $ gdb -q -batch -ex "set trace-commands on" \
- -ex "set logging off" \
- -ex "show logging file" \
- -ex "set logging on" \
- -ex "show logging file"
- +set logging off
- +show logging file
- Future logs will be written to gdb.txt.
- +set logging on
- +show logging file
- Currently logging to "gdb.txt".
- ...
-
- After that commit we have instead:
- ...
- +set logging off
- +show logging file
- The current logfile is "gdb.txt".
- +set logging on
- +show logging file
- The current logfile is "gdb.txt".
- ...
-
- Before the commit, whether logging is enabled or not can be deduced from the
- output of the command. After the commit, the message is unified and it's no
- longer clear whether logging is enabled or not.
-
- Fix this by:
- - adding a new command "show logging enabled"
- - adding a corresponding new command "set logging enabled on/off"
- - making the commands "set logging on/off" deprecated aliases of the
- "set logging enabled on/off" command.
-
- Update the docs and testsuite to use "set logging enabled". Mention the new
- and deprecated commands in NEWS.
-
- Tested on x86_64-linux.

- we get an "entry" event, but no "return" event. This is not what we get

- In commit:

- commit 633cf2548bcd3dafe297e21a1dd3574240280d48

- Remove cleanups from mdebugread.c
-
- the following change was made in the function parse_partial_symbols in
- mdebugread.c:
-
- - fdr_to_pst = XCNEWVEC (struct pst_map, hdr->ifdMax + 1);
- - old_chain = make_cleanup (xfree, fdr_to_pst);
- + gdb::def_vector<struct pst_map> fdr_to_pst_holder (hdr->ifdMax + 1);
- + fdr_to_pst = fdr_to_pst_holder.data ();
-
- The problem with this change is that XCNEWVEC calls xcalloc, which in
- turn calls calloc, and calloc zero initializes the allocated memory.
- In contrast, the new line gdb::def_vector<struct pst_map> specifically
- does not initialize the underlying memory.
-
- This is a problem because, later on in this same function, we
- increment the n_globals field within 'struct pst_map' objects stored
- in the vector. The incrementing is now being done from an
- uninitialized starting point.
-
- In this commit we switch from using gdb::def_vector to using
- std::vector, this alone should be enough to ensure that the fields are
- initialized to zero.
-
- However, for extra clarity, I have also added initial values in the
- 'struct pst_map' to make it crystal clear how the struct will start
- up.

- AArch64: Add support for AArch64 EFI (efi-*-aarch64).
- This adds support for efi-*-aarch64 by virtue of adding a new PEI target
- pei-aarch64-little. This is not a full target and only exists to support EFI
- at this time.
-
- This means that this target does not support relocation processing and is mostly
- a container format. This format has been added to elf based aarch64 targets
- such that efi images can be made natively on Linux.
-
- However this target is not valid for use with gas but only with objcopy.
-
- With these changes the resulting file is recognized as an efi image by
- third party tools:

- gdb: pass more const target_waitstatus by reference
- While working on target_waitstatus changes, I noticed a few places where
- const target_waitstatus objects could be passed by reference instead of
- by pointers. And in some cases, places where a target_waitstatus could
- be passed as const, but was not. Convert them as much as possible.

- gdb: introduce target_waitkind_str, use it in target_waitstatus::to_string
- I would like to print target_waitkind values in debug messages, so I
- think that a target_waitkind-to-string function would be useful. While
- at it, use it in target_waitstatus::to_string. This changes the output
- of target_waitstatus::to_string a bit, but I think it is for the better.
- The debug messages will show a string matching exactly the
- target_waitkind enumerator (minus the TARGET_WAITKIND prefix).
-
- As a convenience, make string_appendf return the same reference to
- string it got as a parameter. This allows doing this:
-
- return string_appendf (str, "foo");
-
- ... keeping the code concise.

- [gdb/symtab] Support .debug_line with DW_FORM_line_strp
- I noticed a new gcc option -gdwarf64 and tried it out (using gcc 11.2.1).
-
- With a test-case hello.c:
- ...
- int
- main (void)
- {
- printf ("hello\n");
- return 0;
- }
- ...
- compiled like this:
- ...
- $ gcc -g -gdwarf64 ~/hello.c
- ...
- I ran into:
- ...
- $ gdb -q -batch a.out
- DW_FORM_line_strp pointing outside of .debug_line_str section \
- [in module a.out]
- ...
-
- Debugging gdb revealed that the string offset is:
- ...
- (gdb) up
- objfile=0x182ab70, str_offset=1378684502312,
- form_name=0xeae9b5 "DW_FORM_line_strp")
- at src/gdb/dwarf2/section.c:208
- 208 error (_("%s pointing outside of %s section [in module %s]"),
- (gdb) p /x str_offset
- $1 = 0x14100000128
- (gdb)
- ...
- which is read when parsing a .debug_line entry at 0x1e0.
-
- Looking with readelf at the 0x1e0 entry, we have:
- ...
- The Directory Table (offset 0x202, lines 2, columns 1):
- Entry Name
- 0 (indirect line string, offset: 0x128): /data/gdb_versions/devel
- 1 (indirect line string, offset: 0x141): /home/vries
- ...
- which in a hexdump looks like:
- ...
- 0x00000200 1f022801 00004101 00000201 1f020f02
- ...
-
- What happens is the following:
- - readelf interprets the DW_FORM_line_strp reference to .debug_line_str as
- a 4 byte value, and sees entries 0x00000128 and 0x00000141.
- - gdb instead interprets it as an 8 byte value, and sees as first entry
- 0x0000014100000128, which is too big so it bails out.
-
- AFAIU, gdb is wrong. It assumes DW_FORM_line_strp is 8 bytes on the basis
- that the corresponding CU is 64-bit DWARF. However, the .debug_line
- contribution has it's own initial_length field, and encodes there that it's
- 32-bit DWARF.
-
- Fix this by using the correct offset size for DW_FORM_line_strp references
- in .debug_line.
-
- Note: the described test-case does trigger this complaint (both with and
- without this patch):
- ...
- $ gdb -q -batch -iex "set complaints 10" a.out
- During symbol reading: intermixed 32-bit and 64-bit DWARF sections
- ...
-
- The reason that the CU has 64-bit dwarf is because -gdwarf64 was passed to
- gcc. The reason that the .debug_line entry has 32-bit dwarf is because that's
- what gas generates. Perhaps this is complaint-worthy, but I don't think it
- is wrong.

- Tested on x86_64-linux, using native and target board dwarf64.exp.

- [gdb/testsuite] Support .debug_line v5 in dwarf assembler

- Add support for this in the dwarf assembler.
-
- For now, make the v5 directory and filename tables work with the v4 type of

- This will need to be properly fixed with an intrusive fix that changes how

- [gdb/testsuite] Speed up MACRO_AT_* calls
- Currently, for each MACRO_AT_range or MACRO_AT_func in dwarf assembly the
- following is done:
- - $srcdir/$subdir/$srcfile is compiled to an executable using

- - a new gdb instance is started
- - the new executable is loaded.
-
- This is inefficient, because the executable is identical within the same

-
- Share the gdb instance in the same Dwarf::assemble invocation, which speeds
- up a make check with RUNTESTFLAGS like this to catch all dwarf assembly

- sim: v850: fix cpu_option testsuite handling
- The v850 testsuite code has been testing the $opt variable, but this
- was never actually set anywhere globally or v850-specific. Instead,
- this was a random variable leaking out of the sh testsuite code. As
- far as I can tell, it has always been this way. That means the code
- only ever tested the v850 cpu target (which is the default).
-
- This failure can be easily seen in practice by running the v850 code
- in isolation and seeing it crash:
- $ runtest v850/allinsns.exp
- ...
- Running target unix
- Using /usr/share/dejagnu/baseboards/unix.exp as board description file for target.
- Using /usr/share/dejagnu/config/unix.exp as generic interface file for target.
- Using ../../../sim/testsuite/config/default.exp as tool-and-target-specific interface file.
- WARNING: Assuming target board is the local machine (which is probably wrong).
- You may need to set your DEJAGNU environment variable.
- Running ../../../sim/testsuite/v850/allinsns.exp ...
- ERROR: tcl error sourcing ../../../sim/testsuite/v850/allinsns.exp.
- ERROR: tcl error code TCL LOOKUP VARNAME opt
- ERROR: can't read "opt": no such variable
- while executing
- "switch -regexp -- $opt {
-
- Backing up a bit, the reason for this logic in the first place is
- because the common sim testsuite code makes an assumption about the
- assembler options with cpu_option -- the option and its value are
- always separated by an =. This is not the case with v850. So tweak
- the core sim logic a bit to support omitting the = so that we can
- switch v850 to the standard all_machs setting and avoid opt entirely.

- Fix intermittent failures on the H8, particularly H8/SX tests.
- The upstream GCC tester has showed spurious execution failures on the
- H8 target for the H8/SX multilibs. I suspected memory corruption or an
- uninitialized variable early as the same binary would sometimes work and
- sometimes it got the wrong result. Worse yet, the point where the test
- determined it was getting the wrong result would change.
-
- Because it only happened on the H8/SX variant I was able to zero in on
- the "mova" support and the "short form" of those instructions in particular.
-
- As the code stands it checks if code->op3.type == 0 to try and identify cases
- where op3 wasn't filled in and thus we've got the short form of the mova
- instruction.
-
- But for the short-form of those instructions we never set any of the "op3"
- data structure. We get whatever was lying around -- it's usually zero and
- thus things usually work, but if the stale data was nonzero, then we'd
- fail to recognize the instruction as a short-form and fail to set up the
- various fields appropriately.
-
- I initially initialized the op3.type field to zero, but didn't like that
- because it was inconsistent with how other operands were initialized.
- Bringing consistency meant using -1 as the initializer value and adjusting
- the check for short form mova appropriately.
-
- I've had this in the upstream GCC tester for perhaps a year at this point
- and haven't seen any of the intermittent failures again.

- ...
-
- [ I configured gdb without explicit settings related to source-highlight, so
- we're excercising the enable_source_highlight=auto scenario. ]
-
- The problem is that:
- - the source-highlight library is build with system compiler
- g++ 7.5.0 which uses the new libstdc++ library abi (see
- https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html )
- - gdb is build using g++ 4.8.5 which uses the old abi.
-
- [ There's a compatibility macro _GLIBCXX_USE_CXX11_ABI, but that doesn't work
- for this case. Instead, it enables the opposite case where the
- source-highlight library is build with g++ 4.8.5 and gdb is build with
- g++ 7.5.0. ]
-
- Fix this by checking whether the source-highlight library is usable during
- configuration.
-
- In the enable_source_highlight=auto scenario, this allows the build to skip
- the unusable library and finish successfully.

- In the enable_source_highlight=yes scenario, this allows the build to error

- gdb: Print cv qualifiers if class attributes are substituted
- Make ptype print const/volatile qualifiers when template or typedef
- attributes are substituted.
-
- For a programm like
- ~~~
- template<typename DataT>
- class Cfoo
- {
- typedef float myfloat;
- public:
- DataT me0;
- const DataT me1=1;
- const myfloat me2=2.0;
- };
-
- int main()
- {
- Cfoo<int> cfoo;
- return 0;
- }
- ~~~
-
- gdb outputs the following type for cfoo's attributes:
-
- ~~~
- (gdb) b 14
- Breakpoint 1 at 0x1170: file tmp.cc, line 14.
- (gdb) run
- Starting program: /tmp
-
- Breakpoint 1, main () at tmp.cc:14
- 14 return 0;
- (gdb) ptype cfoo
- type = class Cfoo<int> [with DataT = int] {
- public:
- DataT me0;
- DataT me1;
- myfloat me2;
-
- private:
- typedef float myfloat;
- }
-
- ~~~
-
- The cv qualifiers (const in this case) are ignored for me1 and me2.
-
- After:
- ~~~
- (gdb) ptype cfoo
- type = class Cfoo<int> [with DataT = int] {
- public:
- DataT me0;
- const DataT me1;
- const myfloat me2;
-
- private:
- typedef float myfloat;
- }
- ~~~

- RISC-V: Support new .option arch directive.
- https://github.com/riscv/riscv-asm-manual/pull/67
-
- Format:
- .option arch, +<extension><version>, ...
- .option arch, -<extension>
- .option arch, =<ISA string>
-
- The new direcitve is used to enable/disable extensions for the specific
- code region. For example,
-
- .attribute arch, "rv64ic" # arch = rv64i2p0_c2p0
- .option push
- .option arch, +d2p0, -c # arch = rv64i2p0_f2p0_d2p0, f is added implied
- .option arch, =rv32gc # arch = rv32i2p0_m2p0_a2p0_f2p0_d2p0_c2p0
- .option pop # arch = rv64i2p0_c2p0
-
- Note that,
- 1. ".option rvc/norvc" have the same behavior as ".option arch +c/-c".
- 2. ".option arch -i" is illegal, since we cannot remove base i extension.
- 3. If arch=rv64i2p0, then ".option arch, +i3p0" will update the i's version
- from 2.0 to 3.0.
- 4. If arch=rv64i3p0, then ".option arch, +i" will update the i's version
- from 2.0 to the default one according to the chosen isa spec.

- RISC-V: Support STO_RISCV_VARIANT_CC and DT_RISCV_VARIANT_CC.
- This is the original discussion,
- https://github.com/riscv/riscv-elf-psabi-doc/pull/190
-
- And here is the glibc part,
- https://sourceware.org/pipermail/libc-alpha/2021-August/129931.html
-
- For binutils part, we need to support a new direcitve: .variant_cc.
- The function symbol marked by .variant_cc means it need to be resolved
- directly without resolver for dynamic linker. We also add a new dynamic
- entry, STO_RISCV_VARIANT_CC, to indicate there are symbols with the
- special attribute in the dynamic symbol table of the object.
-
- I heard that llvm already have supported this in their mainline, so
- I think it's time to commit this.
-
- bfd/
- * elfnn-riscv.c (riscv_elf_link_hash_table): Added variant_cc
- flag. It is used to check if relocations for variant CC symbols
- may be present.
- (allocate_dynrelocs): If the symbol has STO_RISCV_VARIANT_CC
- flag, then raise the variant_cc flag of riscv_elf_link_hash_table.
- (riscv_elf_size_dynamic_sections): Added dynamic entry for
- variant_cc.
- (riscv_elf_merge_symbol_attribute): New function, used to merge
- non-visibility st_other attributes, including STO_RISCV_VARIANT_CC.
- binutils/
- * readelf.c (get_riscv_dynamic_type): New function.
- (get_dynamic_type): Called get_riscv_dynamic_type for riscv targets.
- (get_riscv_symbol_other): New function.
- (get_symbol_other): Called get_riscv_symbol_other for riscv targets.
- gas/
- * config/tc-riscv.c (s_variant_cc): Marked symbol that it follows a
- variant CC convention.
- (riscv_elf_copy_symbol_attributes): Same as elf_copy_symbol_attributes,
- but without copying st_other. If a function symbol has special st_other
- value set via directives, then attaching an IFUNC resolver to that symbol
- should not override the st_other setting.
- (riscv_pseudo_table): Support variant_cc diretive.
- * config/tc-riscv.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Defined.
- * testsuite/gas/riscv/variant_cc-set.d: New testcase.
- * testsuite/gas/riscv/variant_cc-set.s: Likewise.
- * testsuite/gas/riscv/variant_cc.d: Likewise.
- * testsuite/gas/riscv/variant_cc.s: Likewise.
- include/
- * elf/riscv.h (DT_RISCV_VARIANT_CC): Defined to (DT_LOPROC + 1).
- (STO_RISCV_VARIANT_CC): Defined to 0x80.

- Without this commit, doing...
-
- make check RUNTESTFLAGS="--target_board=native-extended-gdbserver" \
- TESTS="gdb.base/dprintf-execution-x-script.exp"
-
- ...will show one failure.
-
- Here's a snippet from gdb.log showing the circumstances - I've trimmed

- Listening on port 2346
- target extended-remote localhost:2346
- Remote debugging using localhost:2346
- ...
- [Tests after this point will pass.]
-
- Note that the command which spawns gdb prevents the gdb script from
- using the native target via "-iex set auto-connect-native-target off".
-
- Moreover, the script in question contains a "run" command, so GDB
- doesn't know how to run (since it's prevented from using the native
- target and no alternate "target" command has been issued. But, once
- GDB finishes starting up, the test will spawn a gdbserver and then
- connect to it. The other (two) tests after this point both pass.
-
- I've fixed this by using gdb_test_multiple instead of gdb_test.
- When a "Don't know how to run message" is received, the test is
- unsupported.
-
- I've also added a comment explaining the reason for needing to check
- for "Don't know how to run" despite bailing out at the top of the test
- via:
-
- if ![target_can_use_run_cmd] {
- return 0
- }

- };
- ^
-
- This happens since commit 345bd07cce3 ("gdb: fix gdbarch_tdep ODR
- violation"), which added default values for ia64_infcall_ops fields. It
- looks like g++ 4.8 doesn't like initializing the ia64_infcall_ops object
- using the brace-enclosed initializer list when the ia64_infcall_ops
- fields are assigned default values.
-
- Later compilers don't have a problem with that, so I suppose that the
- code is correct, but still, change it to make gcc 4.8 happy. Don't
- initialize the fields of ia64_infcall_ops directly, instead
- default-initialize ia64_gdbarch_tdep::infcall_ops.

- so I thought that this file should be named rs6000-aix-tdep.h. But
- there's already a rs6000-aix-tdep.h, so then I though

- [gdb/doc] Fix negative repeat count examining memory example
- The documentation for the examining memory command x contains an example:
- ...
- You can also specify a negative repeat count to examine memory backward from
- the given address. For example, 'x/-3uh 0x54320' prints three halfwords (h)
- at 0x54314, 0x54328, and 0x5431c.
- ...
-
- The 0x54328 looks like a typo, which was intended to be 0x54318.
-
- But the series uses a 4-byte distance, while the halfword size used in the
- command means a 2-byte distance, so the series should be:
- ...
- 0x5431a, 0x5431c, and 0x5431e.
- ...
-
- Fix this by updating the addresses in the example accordingly.

- Reported here ( https://sourceware.org/pipermail/gdb/2021-November/049784.html
- ).

- gdb fix for catch-syscall.exp
- Remove check_continue "execve" from Proc test_catch_syscall_execve.
-
- The check_continue proceedure checs that the command, execve, starts and
- checks for the return from the command. The execve command starts a new
- program and thus the return from the command causing the test to fail.
-
- The call to proc check_continue "execve" is removed and replaced with
- just the call to check_call_to_syscall "execve" to verify the command
- executed. The next test in proc test_catch_syscall_execve verifies that
- the new program started and hit the break point in main.
-
- Update the check for the PowerPC architecture. Power Little Endian systems
- include "le" in the name. The istarget "power64-*-linux*" check fails to
- match LE sytems. The expected string is updated to capture both Big Endian
- and Little Endian systems. Power 10 LE istarget prints as:

- [gdb/build, s390x] Fix build after gdbarch_tdep changes
- Commit 345bd07cce33 ("gdb: fix gdbarch_tdep ODR violation") changes a
- declaration in s390-tdep.h from
-
- struct gdbarch_tdep { ... };
-
- to
-
- struct s390_gdbarch_tdep : gdbarch_tdep { ... };
-
- and now requires that gdbarch_tdep has been declared before. Which is
- usually the case, except when compiling s390-linux-nat.c, where
- s390-tdep.h is included before gdbarch.h. Thus the s390x build errors out
- with the compiler complaining about a missing class name after the colon.
-
- Fix this in s390-linux-nat.c, by including gdbarch.h before s390-tdep.h.

- gdb: fix length of array view returned by some value_contents functions
- In commit 50888e42dcd3 ("gdb: change functions returning value contents
- to use gdb::array_view"), I believe I made a mistake with the length of
- the array views returned by some functions. All functions return a view
- of `TYPE_LENGTH (value_type (type))` length. This is not correct when
- the value's enclosing type is larger than the value's type. In that
- case, the value's contents buffer is of the size of the enclosing type,
- and the value's actual contents is a slice of that (as returned by
- value_contents). So, functions value_contents_all_raw,
- value_contents_for_printing and value_contents_for_printing_const are
- not correct. Since they are meant to return the value's contents buffer
- as a whole, they should have the size of the enclosing type.
-
- There is nothing that uses the returned array view size at the moment,
- so this didn't cause a problem. But it became apparent when trying to
- adjust some callers.

- gdbsupport: remove FUNCTION_NAME
- __func__ is standard C++11:
-
- https://en.cppreference.com/w/cpp/language/function
-
- Also, in C++11, __func__ expands to the demangled function name, so the
- mention in the comment above FUNCTION_NAME doesn't apply anymore.
- Finally, in places where FUNCTION_NAME is used, I think it's enough to
- print the function name, no need to print the whole signature.
- Therefore, I propose to just remove FUNCTION_NAME and update users to

- gdbsupport: move xfree into its own file
- In the next commit I'd like to reference gdb_unique_ptr within the

- gdb_unique_ptr.h, which requires that xfree be defined.
-
- Interestingly, gdb_unique_ptr.h doesn't actually include anything that
- defines xfree, but I was finding that when I added a gdb_unique_ptr.h
- include to common-utils.h I was getting a dependency cycle; before my
- change xfree was defined when gdb_unique_ptr.h was processed, while
- after my change it was not, and this made g++ unhappy.
-
- To break this cycle, I propose to move xfree into its own header file,

- gdb: throw OPTIMIZED_OUT_ERROR rather than GENERIC_ERROR
- While reviewing this patch:
-
- https://sourceware.org/pipermail/gdb-patches/2021-November/183227.html
-
- I spotted that the patch could be improved if we threw
- OPTIMIZED_OUT_ERROR rather than GENERIC_ERROR in a few places.
-
- This commit updates error_value_optimized_out and
- require_not_optimized_out to throw OPTIMIZED_OUT_ERROR.
-
- I ran the testsuite and saw no regressions. This doesn't really
- surprise me, we don't usually write code like:
-
- catch (const gdb_exception_error &ex)
- {
- (if ex.error == GENERIC_ERROR)
- ...
- else
- ...
- }
-
- There are a three places where we write something like:
-
- catch (const gdb_exception_error &ex)
- {
- (if ex.error == OPTIMIZED_OUT_ERROR)
- ...
- }
-
- In frame.c:unwind_pc, stack.c:info_frame_command_core, and
- value.c:value_optimized_out, but if we are hitting these cases then
- it's not significantly changing GDB's behaviour.

- gdb: rework "set debuginfod" commands
- As discussed here [1], do some re-work in the "set debuginfod commands".
-
- First, use "set debuginfod enabled on/off/ask" instead of "set
- debuginfod on/off/ask". This is more MI-friendly, and it gives an
- output that makes more sense in "info set", for example.
-
- Then, make the show commands not call "error" when debuginfod support is
- not compiled in. This makes the commands "show" and "show debuginfod"
- stop early, breaking gdb.base/default.exp:
-
- Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.base/default.exp ...
- FAIL: gdb.base/default.exp: info set
- FAIL: gdb.base/default.exp: show
-
- - Make the "debuginfod enabled" setting default to "off" when debuginfod
- support is not compiled in, and "ask" otherwise.
- - Make the setter of "debuginfod enabled" error out when debuginfod
- support is not compiled in, so that "debuginfod enabled" will always
- remain "off" in that case.
- - Make the setter of "debuginfod verbose" work in any case. I don't
- see the harm in letting the user change that setting, since the user will
- hit an error if they try to enable the use of debuginfod.
- - I would do the same for the "debuginfod urls" setter, but because
- this one needs to see the DEBUGINFOD_URLS_ENV_VAR macro, provided by
- libdebuginfod, I made that one error out as well if debuginfod
- support is not compiled it (otherwise, I would have left it like
- "debuginfod verbose". Alternatively, we could hard-code
- "DEBUGINFOD_URLS" in the code (in fact, it was prior to this patch,
- but I think it was an oversight, as other spots use
- DEBUGINFOD_URLS_ENV_VAR), or use a dummy string to store the setting,
- but I don't really see the value in that.
-
- Rename debuginfod_enable to debuginfod_enabled, just so it matches the
- setting name.

- gdb: fix gdbarch_tdep ODR violation
- I would like to be able to use non-trivial types in gdbarch_tdep types.
- This is not possible at the moment (in theory), because of the one
- definition rule.
-
- To allow it, rename all gdbarch_tdep types to <arch>_gdbarch_tdep, and
- make them inherit from a gdbarch_tdep base class. The inheritance is
- necessary to be able to pass pointers to all these <arch>_gdbarch_tdep
- objects to gdbarch_alloc, which takes a pointer to gdbarch_tdep.
-
- These objects are never deleted through a base class pointer, so I
- didn't include a virtual destructor. In the future, if gdbarch objects
- deletable, I could imagine that the gdbarch_tdep objects could become
- owned by the gdbarch objects, and then it would become useful to have a
- virtual destructor (so that the gdbarch object can delete the owned
- gdbarch_tdep object). But that's not necessary right now.
-
- It turns out that RISC-V already has a gdbarch_tdep that is
- non-default-constructible, so that provides a good motivation for this
- change.
-
- Most changes are fairly straightforward, mostly needing to add some
- casts all over the place. There is however the xtensa architecture,
- doing its own little weird thing to define its gdbarch_tdep. I did my
- best to adapt it, but I can't test those changes.

- Deal with full path in .file 0 directive
- Gas uses the directory part, if present, of the .file 0 directive to set
- entry 0 of the directory table in DWARF 5, which represents the "current
- directory".
-
- Now Gas also uses the file part of the same directive to set entry 0 of the
- file table, which represents the "current compilation file". But the latter
- need not be located in the former so GCC will use a full path in the file
- part when it is passed a full path:
-
- gcc -c /full/path/test.c -save-temps
-
- yields:
-
- .file 0 "/current/directory" "/full/path/test.c"
-
- in the assembly file and:
-
- The Directory Table (offset 0x22, lines 2, columns 1):
- Entry Name

- sim: cris: make error message test a little more flexible
- The point of this test is to just make sure the usage text is shown,
- not the exact details of the usage text. So shorten the output test
- to match the beginning. This fixes breakage when the output changed
- slightly to include [--].
-
- sim: run: fix crash in argc==0 error situation
- The new argv processing code assumed that we were always passed a
- command line. If we weren't, make sure we don't crash before we
- get a chance to output an error message about incorrect usage.
-
- sim: cris: touch up rvdummy handling
- Add quiet build support and make sure it's removed with `make clean`.
-
- sim: cris: replace custom "dest" test field with new --argv0
- The #dest field used in the cris testsuite is a bit of hack to set the
- argv[0] for the tests to read out later on. Now that the sim has an
- option to set argv[0] explicitly, we don't need this custom field, so
- let's drop it to harmonize the testsuites a little.
-
- sim: run: add --argv0 option to control argv[0]
- We default argv[0] to the program we run which is a standard *NIX
- convention, but sometimes we want to be able to control the argv[0]
- setting independently (especially for programs that inspect argv[0]
- to change their behavior or output). Add an option to control it.

- sim: split program path out of argv vector
- We use the program argv to both find the program to run (argv[0]) and
- to hold the arguments to the program. Most of the time this is fine,
- but if we want to let programs specify argv[0] independently (which is
- possible in standard *NIX programs), this double duty doesn't work.
-
- So let's split the path to the program to run out into a separate
- field by itself. This simplifies the various sim_open funcs too.
-
- By itself, this code is more of a logical cleanup than something that
- is super useful. But it will open up customization of argv[0] in a
- follow up commit. Split the changes to make it easier to review.

- gdb: fix "set scheduler-locking" thread exit hang
- GDB hangs when doing this:
-
- - launch inferior with multiple threads
- - multiple threads hit some breakpoint(s)
- - one breakpoint hit is presented as a stop, the rest are saved as
- pending wait statuses
- - "set scheduler-locking on"
- - resume the currently selected thread (because of scheduler-locking,
- it's the only one resumed), let it execute until exit
- - GDB hangs, not showing the prompt, impossible to interrupt with ^C
-
- When the resumed thread exits, we expect the target to return a
- TARGET_WAITKIND_NO_RESUMED event, and that's what we see:
-
- [infrun] fetch_inferior_event: enter
- [infrun] scoped_disable_commit_resumed: reason=handling event
- [infrun] random_pending_event_thread: None found.
- [Thread 0x7ffff7d9c700 (LWP 309357) exited]
- [infrun] print_target_wait_results: target_wait (-1.0.0 [process -1], status) =
- [infrun] print_target_wait_results: -1.0.0 [process -1],
- [infrun] print_target_wait_results: status->kind = no-resumed
- [infrun] handle_inferior_event: status->kind = no-resumed
- [infrun] handle_no_resumed: TARGET_WAITKIND_NO_RESUMED (ignoring: found resumed)
- [infrun] prepare_to_wait: prepare_to_wait
- [infrun] reset: reason=handling event
- [infrun] maybe_set_commit_resumed_all_targets: not requesting commit-resumed for target native, no resumed threads
- [infrun] fetch_inferior_event: exit
-
- The problem is in handle_no_resumed: we check if some other thread is
- actually resumed, to see if we should ignore that event (see comments in
- that function for more info). If this condition is true:
-
- (thread->executing () || thread->has_pending_waitstatus ())
-
- ... then we ignore the event. The problem is that there are some non-resumed
- threads with a pending event, which makes us ignore the event. But these
- threads are not resumed, so we end up waiting while nothing executes, hence
- waiting for ever.
-
- My first fix was to change the condition to:
-
- (thread->executing ()
- || (thread->resumed () && thread->has_pending_waitstatus ()))
-
- ... but then it occured to me that we could simply check for:
-
- (thread->resumed ())
-
- Since "executing" implies "resumed", checking simply for "resumed"
- covers threads that are resumed and executing, as well as threads that
- are resumed with a pending status, which is what we want.

-
- For the current objdump, we dump data to .byte/.short/.word/.dword, and
- dump the unknown or unsupported instructions to .2byte/.4byte/.8byte, which
- respectively are 2, 4 and 8 bytes instructions. Therefore, we shouldn't
- dump the 0x0001 as a c.nop instruction in the above case, we should dump
- it to .2byte 0x1 as a unknown instruction, since the rvc is disabled.
-
- However, consider that some people may use the new objdump to dump the old
- objects, which don't have any elf attributes. We usually set the default
- architecture string to rv64g by bfd/elfxx-riscv.c:riscv_set_default_arch.
- But this will cause rvc instructions to be unrecognized. Therefore, we
- set the default architecture string to rv64gc for disassembler, to keep
- the previous behavior.
-
- This patch pass the riscv-gnu-toolchain gcc/binutils regressions for
- rv32emc-elf, rv32gc-linux, rv32i-elf, rv64gc-elf and rv64gc-linux
- toolchains. Also, tested by --enable-targets=all and can build

- [gdb/testsuite] Add gdb.opt/break-on-_exit.exp
- Add a test-case to excercise the problem scenario reported in PR28527 and
- fixed in commit a50bdb99afe "[gdb/tdep, rs6000] Don't skip system call in
- skip_prologue":
- - set a breakpoint on _exit, and
- - verify that it triggers.
-
- Note that this is not a regression test for that commit. Since the actual
- code in _exit may vary across os instances, we cannot guarantee that the
- problem will always trigger with this test-case.
-
- Rather, this test-case is a version of the original test-case
- (gdb.threads/process-dies-while-detaching.exp) that is minimal while still
- reproducing the problem reported in PR28527, in that same setting.
-
- The benefit of this test-case is that it exercise real-life code and may
- expose similar problems in other settings. Also, it provides a much easier
- test-case to investigate in case a similar problem occurs.
-
- Tested on x86_64-linux and ppc64le-linux.

-
- Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28308
-
- The name of this new test was based on that of an existing test,
- bp-cmds-execution-x-script.exp. I started off by copying that test,
- adding to it, and then rewriting almost all of it. It's different

- Fix PR 28308 - dprintf breakpoints not working when run from script
- This commit fixes Bug 28308, titled "Strange interactions with
- dprintf and break/commands":
-
- Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28308
-
- Since creating that bug report, I've found a somewhat simpler way of
- reproducing the problem. I've encapsulated it into the GDB test case
- which I've created along with this bug fix. The name of the new test
- is gdb.base/dprintf-execution-x-script.exp, I'll demonstrate the
- problem using this test case, though for brevity, I've placed all
- relevant files in the same directory and have renamed the files to all
- start with 'dp-bug' instead of 'dprintf-execution-x-script'.
-
- The script file, named dp-bug.gdb, consists of the following commands:
-
- dprintf increment, "dprintf in increment(), vi=%d\n", vi
- break inc_vi
- commands
- continue
- end
- run
-
- Note that the final command in this script is 'run'. When 'run' is
- instead issued interactively, the bug does not occur. So, let's look
- at the interactive case first in order to see the correct/expected
- output:
-
- $ gdb -q -x dp-bug.gdb dp-bug
- ... eliding buggy output which I'll discuss later ...
- (gdb) run
- Starting program: /mesquite2/sourceware-git/f34-master/bld/gdb/tmp/dp-bug
- vi=0
- dprintf in increment(), vi=0
-
- Breakpoint 2, inc_vi () at dprintf-execution-x-script.c:26
- 26 in dprintf-execution-x-script.c
- vi=1
- dprintf in increment(), vi=1
-
- Breakpoint 2, inc_vi () at dprintf-execution-x-script.c:26
- 26 in dprintf-execution-x-script.c
- vi=2
- dprintf in increment(), vi=2
-
- Breakpoint 2, inc_vi () at dprintf-execution-x-script.c:26
- 26 in dprintf-execution-x-script.c
- vi=3
- [Inferior 1 (process 1539210) exited normally]
-
- In this run, in which 'run' was issued from the gdb prompt (instead
- of at the end of the script), there are three dprintf messages along
- with three 'Breakpoint 2' messages. This is the correct output.
-
- Now let's look at the output that I snipped above; this is the output
- when 'run' is issued from the script loaded via GDB's -x switch:
-
- $ gdb -q -x dp-bug.gdb dp-bug
- Reading symbols from dp-bug...
- Dprintf 1 at 0x40116e: file dprintf-execution-x-script.c, line 38.
- Breakpoint 2 at 0x40113a: file dprintf-execution-x-script.c, line 26.
- vi=0
- dprintf in increment(), vi=0
-
- Breakpoint 2, inc_vi () at dprintf-execution-x-script.c:26
- 26 dprintf-execution-x-script.c: No such file or directory.
- vi=1
-
- Breakpoint 2, inc_vi () at dprintf-execution-x-script.c:26
- 26 in dprintf-execution-x-script.c
- vi=2
-
- Breakpoint 2, inc_vi () at dprintf-execution-x-script.c:26
- 26 in dprintf-execution-x-script.c
- vi=3
- [Inferior 1 (process 1539175) exited normally]
-
- In the output shown above, only the first dprintf message is printed.
- The 2nd and 3rd dprintf messages are missing! However, all three
- 'Breakpoint 2...' messages are still printed.
-
- Why does this happen?
-
- bpstat_do_actions_1() in gdb/breakpoint.c contains the following
- comment and code near the start of the function:
-
- /* Avoid endless recursion if a `source' command is contained
- in bs->commands. */
- if (executing_breakpoint_commands)
- return 0;
-
- scoped_restore save_executing
- = make_scoped_restore (&executing_breakpoint_commands, 1);
-
- Also, as described by this comment prior to the 'async' field
- in 'struct ui' in top.h, the main UI starts off in sync mode
- when processing command line arguments:
-
- /* True if the UI is in async mode, false if in sync mode. If in
- sync mode, a synchronous execution command (e.g, "next") does not
- return until the command is finished. If in async mode, then
- running a synchronous command returns right after resuming the
- target. Waiting for the command's completion is later done on
- the top event loop. For the main UI, this starts out disabled,
- until all the explicit command line arguments (e.g., `gdb -ex
- "start" -ex "next"') are processed. */
-
- This combination of things, the state of the static global
- 'executing_breakpoint_commands' plus the state of the async
- field in the main UI causes this behavior.
-
- This is a backtrace after hitting the dprintf breakpoint for
- the second time when doing 'run' from the script file, i.e.
- non-interactively:

- This relatively short backtrace is due to the current UI's async field
- being set to 1.
-
- Yet another thing to be aware of regarding this problem is the
- difference in the way that commands associated to dprintf breakpoints
- versus regular breakpoints are handled. While they both use a command
- list associated with the breakpoint, regular breakpoints will place
- the commands to be run on the bpstat chain constructed in
- bp_stop_status(). These commands are run later on. For dprintf
- breakpoints, commands are run via the 'after_condition_true' function
- pointer directly from bpstat_stop_status(). (The 'commands' field in
- the bpstat is cleared in dprintf_after_condition_true(). This
- prevents the dprintf commands from being run again later on when other
- commands on the bpstat chain are processed.)
-
- Another thing that I noticed is that dprintf breakpoints are the only
- type of breakpoint which use 'after_condition_true'. This suggests
- that one possible way of fixing this problem, that of making dprintf
- breakpoints work more like regular breakpoints, probably won't work.
- (I must admit, however, that my understanding of this code isn't
- complete enough to say why. I'll trust that whoever implemented it
- had a good reason for doing it this way.)
-
- The comment referenced earlier regarding 'executing_breakpoint_commands'
- states that the reason for checking this variable is to avoid
- potential endless recursion when a 'source' command appears in
- bs->commands. We know that a dprintf command is constrained to either
- 1) execution of a GDB printf command, 2) an inferior function call of
- a printf-like function, or 3) execution of an agent-printf command.
- Therefore, infinite recursion due to a 'source' command cannot happen
- when executing commands upon hitting a dprintf breakpoint.
-
- I chose to fix this problem by having dprintf_after_condition_true()
- directly call execute_control_commands(). This means that it no
- longer attempts to go through bpstat_do_actions_1() avoiding the
- infinite recursion check for potential 'source' commands on the
- command chain. I think it simplifies this code a little bit too, a
- definite bonus.
-
- Summary:
-
- * breakpoint.c (dprintf_after_condition_true): Don't call
- bpstat_do_actions_1(). Call execute_control_commands()
- instead.

- Improve gdb::array_view ctor from contiguous containers
- While reading the interface of gdb::array_view, I realized that the
- constructor that builds an array_view on top of a contiguous container
- (such as std::vector, std::array or even gdb::array_view) can be
- missused.
-
- Lets consider the following code sample:
-
- struct Parent
- {
- Parent (int a): a { a } {}
- int a;
- };
-
- std::ostream &operator<< (std::ostream& os, const Parent & p)
- { os << "Parent {a=" << p.a << "}"; return os; }
-
- struct Child : public Parent
- {
- Child (int a, int b): Parent { a }, b { b } {}
- int b;
- };
-
- std::ostream &operator<< (std::ostream& os, const Child & p)
- { os << "Child {a=" << p.a << ", b=" << p.b << "}"; return os; }
-
- template <typename T>
- void print (const gdb::array_view<const T> &p)
- {
- std::for_each (p.begin (), p.end (), [](const T &p) { std::cout << p << '\n'; });
- }
-
- Then with the current interface nothinng prevents this usage of
- array_view to be done:
-
- const std::array<Child, 3> elts = {
- Child {1, 2},
- Child {3, 4},
- Child {5, 6}
- };
- print_all<Parent> (elts);
-
- This compiles fine and produces the following output:
-
- Parent {a=1}
- Parent {a=2}
- Parent {a=3}
-
- which is obviously wrong. There is nowhere in memory a Parent-like
- object for which the A member is 2 and this call to print_all<Parent>
- shold not compile at all (calling print_all<Child> is however fine).
-
- This comes down to the fact that a Child* is convertible into a Parent*,
- and that an array view is constructed to a pointer to the first element
- and a size. The valid type pointed to that can be used with this
- constructor are restricted using SFINAE, which requires that a
- pointer to a member into the underlying container can be converted into a
- pointer the array_view's data type.
-
- This patch proposes to change the constraints on the gdb::array_view
- ctor which accepts a container now requires that the (decayed) type of
- the elements in the container match the (decayed) type of the array_view
- being constructed.
-
- Applying this change required minimum adjustment in GDB codebase, which
- are also included in this patch.
-
- Tested by rebuilding.

- gdb: tweak scoped_disable_commit_resumed uses when resuming all threads in non-stop
- When doing "continue -a" in non-stop mode, each thread is individually
- resumed while the commit resumed state is enabled. This forces the
- target to commit each resumption immediately, instead of being able to
- batch things.
-
- The reason is that there is no scoped_disable_commit_resumed around the
- loop over threads in continue_1, when "non_stop && all_threads" is true.
- Since the proceed function is called once for each thread, the
- scoped_disable_commit_resumed in proceed therefore forces commit-resumed
- between each thread resumption. Add the necessary
- scoped_disable_commit_resumed in continue_1 to avoid that.
-
- I looked at the MI side of things, the function exec_continue, and found
- that it was correct. There is a similar iteration over threads, and
- there is a scoped_disable_commit_resumed at the function scope. This is
- not wrong, but a bit more than we need. The branches that just call
- continue_1 do not need it, as continue_1 takes care of disabling commit
- resumed. So, move the scoped_disable_commit_resumed to the inner scope
- where we iterate on threads and proceed them individually.
-
- Here's an example debugging a multi-threaded program attached by
- gdbserver (debug output trimmed for brevity):
-
- $ ./gdb -nx -q --data-directory=data-directory -ex "set non-stop" -ex "tar rem :1234"
- (gdb) set debug remote
- (gdb) set debug infrun
- (gdb) c -a
- Continuing.

-
- Avoid /proc/pid/mem races (PR 28065)
- PR 28065 (gdb.threads/access-mem-running-thread-exit.exp intermittent
- failure) shows that GDB can hit an unexpected scenario -- it can
- happen that the kernel manages to open a /proc/PID/task/LWP/mem file,
- but then reading from the file returns 0/EOF, even though the process
- hasn't exited or execed.
-
- "0" out of read/write is normally what you get when the address space
- of the process the file was open for is gone, because the process
- execed or exited. So when GDB gets the 0, it returns memory access
- failure. In the bad case in question, the process hasn't execed or
- exited, so GDB fails a memory access when the access should have
- worked.
-
- GDB has code in place to gracefully handle the case of opening the
- /proc/PID/task/LWP/mem just while the LWP is exiting -- most often the
- open fails with EACCES or ENOENT. When it happens, GDB just tries
- opening the file for a different thread of the process. The testcase
- is written such that it stresses GDB's logic of closing/reopening the
- /proc/PID/task/LWP/mem file, by constantly spawning short lived
- threads.
-
- However, there's a window where the kernel manages to find the thread,
- but the thread exits just after and clears its address space pointer.
- In this case, the kernel creates a file successfully, but the file
- ends up with no address space associated, so a subsequent read/write
- returns 0/EOF too, just like if the whole process had execed or
- exited. This is the case in question that GDB does not handle.
-
- Oleg Nesterov gave this suggestion as workaround for that race:
-
- gdb can open(/proc/pid/mem) and then read (say) /proc/pid/statm.
- If statm reports something non-zero, then open() was "successfull".
-
- I think that might work. However, I didn't try it, because I realized
- we have another nasty race that that wouldn't fix.
-
- The other race I realized is that because we close/reopen the
- /proc/PID/task/LWP/mem file when GDB switches to a different inferior,
- then it can happen that GDB reopens /proc/PID/task/LWP/mem just after
- a thread execs, and before GDB has seen the corresponding exec event.
- I.e., we can open a /proc/PID/task/LWP/mem file accessing the
- post-exec address space thinking we're accessing the pre-exec address
- space.
-
- A few months back, Simon, Oleg and I discussed a similar race:
-
- [Bug gdb/26754] Race condition when resuming threads and one does an exec
- https://sourceware.org/bugzilla/show_bug.cgi?id=26754
-
- The solution back then was to make the kernel fail any ptrace
- operation until the exec event is consumed, with this kernel commit:
-
- commit dbb5afad100a828c97e012c6106566d99f041db6
- Author: Oleg Nesterov <oleg@redhat.com>
- AuthorDate: Wed May 12 15:33:08 2021 +0200
- Commit: Linus Torvalds <torvalds@linux-foundation.org>
- CommitDate: Wed May 12 10:45:22 2021 -0700
-
- ptrace: make ptrace() fail if the tracee changed its pid unexpectedly
-
- This however, only applies to ptrace, not to the /proc/pid/mem file
- opening case. Also, even if it did apply to the file open case, we
- would want to support current kernels until such a fix is more wide
- spread anyhow.
-
- So all in all, this commit gives up on the idea of only ever keeping
- one /proc/pid/mem file descriptor open. Instead, make GDB open a
- /proc/pid/mem per inferior, and keep it open until the inferior exits,
- is detached or execs. Make GDB open the file right after the inferior
- is created or is attached to or forks, at which point we know the
- inferior is stable and stopped and isn't thus going to exec, or have a
- thread exit, and so the file open won't fail (unless the whole process
- is SIGKILLed from outside GDB, at which point it doesn't matter
- whether we open the file).
-
- This way, we avoid both races described above, at the expense of using
- more file descriptors (one per inferior).

- gdb/testsuite: use gdb_get_line_number
- Replaces a hard coded line number with a use of gdb_get_line_number.
-
- I suspect that the line number has, over time, come adrift from where

- 770 pointed at the final 'return 0' in function main. Over time, as
- things have been added, line 770 now points at some random location in

- So, I've marked the 'return 0' with a comment, and now the test will

- gdb: introduce "set index-cache enabled", deprecate "set index-cache on/off"
- The "set index-cache" command is used at the same time as a prefix
- command (prefix for "set index-cache directory", for example), and a
- boolean setting for turning the index-cache on and off. Even though I
- did introduce that, I now don't think it's a good idea to do something
- non-standard like this.
-
- First, there's no dedicated CLI command to show whether the index-cache
- is enabled, so it has to be custom output in the "show index-cache
- handler". Also, it means there's no good way a MI frontend can find out
- if the index-cache is enabled. "-gdb-show index-cache" doesn't show it
- in the MI output record:
-
- (gdb) interpreter-exec mi "-gdb-show index-cache"
- ~"\n"
- ~"The index cache is currently disabled.\n"
- ^done,showlist={option={name="directory",value="/home/simark/.cache/gdb"}}
-
- Fix this by introducing "set/show index-cache enabled on/off", regular
- boolean setting commands. Keep commands "set index-cache on" and "set
- index-cache off" as deprecated aliases of "set index-cache enabled",
- with respectively the default arguments "on" and "off".
-
- Update tests using "set index-cache on/off" to use the new command.
- Update the regexps in gdb.base/maint.exp to figure out whether the
- index-cache is enabled or not. Update the doc to mention the new
- commands.

- gdb: pass/return setting setter/getter scalar values by value
- The getter and setter in struct setting always receive and return values
- by const reference. This is not necessary for scalar values (like bool
- and int), but more importantly it makes it a bit annoying to write a
- getter, you have to use a scratch static variable or something similar
- that you can refer to:
-
- const bool &
- my_getter ()
- {
- static bool value;
- value = function_returning_bool ();
- return value;
- }
-
- Change the getter and setter function signatures to receive and return
- value by value instead of by reference, when the underlying data type is
- scalar. This means that string-based settings will still use
- references, but all others will be by value. The getter above would
- then be re-written as:
-
- bool
- my_getter ()
- {
- return function_returning_bool ();
- }
-
- This is useful for a patch later in this series that defines a boolean
- setting with a getter and a setter.

- [AArch64] Make gdbserver register set selection dynamic
- The current register set selection mechanism for AArch64 is static, based
- on a pre-populated array of register sets.
-
- This means that we might potentially probe register sets that are not
- available. This is OK if the kernel errors out during ptrace, but probing the
- tag_ctl register, for example, does not result in a ptrace error if the kernel
- supports the tagged address ABI but not MTE (PR 28355).
-
- Making the register set selection dynamic, based on feature checks, solves
- this and simplifies the code a bit. It allows us to list all of the register
- sets only once, and pick and choose based on HWCAP/HWCAP2 or other properties.
-
- I plan to backport this fix to GDB 11 as well.

- SUMMARY: AddressSanitizer: alloc-dealloc-mismatch (/usr/lib64/libasan.so.6+0xb0fa7) in operator delete[](void*)
- ==1909567==HINT: if you don't care about these errors you may set ASAN_OPTIONS=alloc_dealloc_mismatch=0
- ==1909567==ABORTING
-
- Despite the code called properly operator new[] and operator delete[].
- But GDB's new-op.cc provides its own operator new[] which gets translated into
- malloc() (which gets recogized as operatore new(size_t)) but as it does not
- translate also operators delete[] Address Sanitizer gets confused.
-
- The question is how many variants of the delete operator need to be provided.
- There could be 14 operators new but there are only 4, GDB uses 3 of them.
- There could be 16 operators delete but there are only 6, GDB uses 2 of them.
- It depends on libraries and compiler which of the operators will get used.
- Currently being used:
- U operator new[](unsigned long)
- U operator new(unsigned long)
- U operator new(unsigned long, std::nothrow_t const&)
- U operator delete[](void*)
- U operator delete(void*, unsigned long)
-
- Tested on x86_64-linux.

- asan: dlltool buffer overflow: embedded NUL in string
- yyleng gives the pattern length, xstrdup just copies up to the NUL.
- So it is quite possible writing at an index of yyleng-2 overflows
- the xstrdup allocated string buffer. xmemdup quite handily avoids
- this problem, even writing the terminating NUL over the trailing
- quote. Use it in ldlex.l too where we'd already had a report of this
- problem and fixed it by hand, and to implement xmemdup0 in gas.

- sim: mloop: mark a few conditionally used funcs as unused
- These are marked inline, so building w/gcc at higher optimization
- levels will automatically discard them. But building with -O0 will
- trigger unused function warnings, so fix that.
-
- The common before/after cover functions in the common mloop generator
- are not used by all architecture ports. Doesn't seem to be a hard
- requirement, so marking them optional (i.e. unused) is fine.
-
- The cris execute function is conditionally used depending on the
- fast-build mode settings, so mark it unused too.

- asan: assert (addr_ranges) <= (start)
- That assert would be more obvious if it were reported as
- "addr_ranges <= end_ranges". Fix that by using the obvious variable
- in the final loop. Stop the assertion by using a signed comparison:
- It's possible for the rounding up of the arange pointer to exceed the
- end of the block when the block size is fuzzed.
-
- * dwarf.c (display_debug_aranges): Use "end_ranges" in loop

- [gdb/tdep, rs6000] Don't skip system call in skip_prologue
- I ran into a case where a breakpoint on _exit never triggered, because it was
- set past the end of the _exit prologue, past the end of the exit_group system
- call (which does not return).
-
- More concretely, the breakpoint was set at the last insn show here:

- don't need the arch-specific flexibility. Further, these are only

- other userland runtimes (like Linux). Let's simplify to make this
- easier to understand & build. We don't namespace the variables yet,
- but sets up the framework for it.
-
- Create a new target-newlib-errno.c template file. The template file
- is hand written, but the inline map is still automatically generated.
-
- This allows us to move it to the common set of objects so it's only

-
- Now we can remove the output from the gentmap build-time tool since
- it's checked into the tree.
-
- Then we stop including the errno lists in nltvals.def since nothing
- uses it.

- sim: fix compilation on mingw64 [PR sim/28476]
- ...by reordering includes.
-
- 1. sim-utils.c
-
- sim/mips/sim-main.h defines UserMode, while there is a struct in winnt.h
- which has UserMode as a member. So if sim-main.h is included before winnt.h,
- compilation fails.
-
- 2. ppc
-
- registers.h defines CR, which is used as a member in winnt.h.
-
- winsock2.h is included by sys/time.h, so sys/time.h has to be included

- Don't include coff/pe.h in coff-x86_64.c
- This (and other) code from coffcode.h is broken for x86_64_coff_vec,
- and has been ever since support was added in 2006 commit 99ad839030c1
- Here, bfd_coff_aoutsz must match coff_swap_aouthdr_out otherwise we
- end up writing garbage.

-
- We have removed support for --target=x86_64-coff, likely because it
- never worked properly, but still produce coff-x86_64.o with
- --enable-targets=all. This means objcopy can recognize x86_64 COFF
- files but will write garbage to the output file, a fact found by
- fuzzers. I suspect x86_64 COFF is still broken after this fix, and
- mention of coff-x86_64.* should be removed from bfd/Makefile.am.

- That's because when compiling with C++ >= 17, we use the standard

- Document resolve_dynamic_type oddity
- Today I re-learned that resolve_dynamic_type can return a type for
- which is_dynamic_type returns true. This can happen for an array
- whose elements have dynamic type -- the array is reported as dynamic,
- but resolving the elements would be incorrect, because each element
- might have a different type after resolution.
-
- You can see the special case in resolve_dynamic_array_or_string:
-
- if (ary_dim != NULL && ary_dim->code () == TYPE_CODE_ARRAY)
- ...
- else
- ...
-
- I looked into having the TYPE_CODE_ARRAY case in
- is_dynamic_type_internal follow this same logic, but that breaks down
- on the gdb.fortran/dynamic-ptype-whatis.exp test case. In particular
- this code in fortran_undetermined::evaluate:
-
- value *callee = std::get<0> (m_storage)->evaluate (nullptr, exp, noside);
- if (noside == EVAL_AVOID_SIDE_EFFECTS
- && is_dynamic_type (value_type (callee)))
- callee = std::get<0> (m_storage)->evaluate (nullptr, exp, EVAL_NORMAL);
-
- ... relies on is_dynamic_type returning true for such an array.
-
- I wasn't really sure of the best way to fix this, so in the meantime I
- wrote this patch, which documents the oddity so that I might have a
- chance of remembering this in the future.

- Avoid self-test failures on x86-linux
- The disassembly tests in "maint selftest" will fail on x86-linux.
- This happens because opcodes rejects an attempt to disassemble for an
- arch with a 64-bit address size when bfd_vma is 32-bit.
-
- This patch avoids this problem by avoiding the test in this case. I
- chose to do it this way because this seems to be the only situation
- where opcodes checks the size of bfd_vma.
-
- For v2 of this patch, I've also updated memory_error_test to do the
- same thing. This is needed due to the "improve error reporting from
- the disassembler" patch.

- This patch also adds the "maint set/show selftest verbose" setting. It

- [gdb/symtab] Handle DW_AT_string_length with location list
- Consider a fortran routine where a string variable s is modified:
- ...
- subroutine f(s)
- character*(*) s
- print *, s
- s(1:3) = 'oof'
- print *, s
- end subroutine f
- ...
-
- When compiling with optimization level -O1 and printing the type of
- variable s we get:
- ...
- $ gdb -q -batch outputs/gdb.opt/fortran-string/fortran-string \
- -ex "b f" \
- -ex run \
- -ex "ptype s"
- Breakpoint 1 at 0x4006f7: file fortran-string.f90, line 21.
-
- Breakpoint 1, f (s=..., _s=_s@entry=3) at fortran-string.f90:21
- 21 subroutine f(s)
- type = character*1
- ...
- while with -O0 we have instead:
- ...
- type = character (3)
- ...
-
- The problem is that the type of s is:
- ...
- <1><2d6>: Abbrev Number: 21 (DW_TAG_string_type)
- <2d7> DW_AT_string_length: 0xbf (location list)
- <2db> DW_AT_byte_size : 4
- ...
- where the DW_AT_string_length is a location list, a case that is not handled
- by attr_to_dynamic_prop.
-
- Fix this by handling attr->form_is_section_offset () in attr_to_dynamic_prop.
-
- Tested on x86_64-linux.
-
- The test-case is based on gdb.opt/fortran-string.exp from
- https://src.fedoraproject.org/rpms/gdb/raw/f32/f/gdb-archer-vla-tests.patch .
- I've updated the copyrights to stretch to 2021.

- manage. ]

- In the testcase, "p_union" is an unused/uninitialized variable of

- union/struct variables at any optimization level. Since the compiler
- itself is not emitting the symbol for "p_union", debug info is also

- Fix watchpoints with multiple threads on Windows
- A recent internal change pointed out that watchpoints were not working
- on Windows when the inferior was multi-threaded. This happened
- because the debug registers were only updated for certain threads --
- in particular, those that were being resumed and that were not marked
- as suspended. In the case of single-stepping, the need to update the
- debug registers in other threads could also be "forgotten".
-
- This patch changes windows-nat.c to mark all threads needing a debug
- register update. This brings the code closer to what gdbserver does
- (though, unfortunately, it still seems more complicated than needed).

- [gdb/testsuite] Fix port detection in gdb.debuginfod/fetch_src_and_symbols.exp

- ...
- Failed to listen for connections: Address already in use^M

- The test-case is trying to start debuginfod on a port to see if it's
- available, and it handles either this message:
- "started http server on IPv4 IPv6 port=$port"
- meaning success, or:
- "failed to bind to port"
- meaning failure, in which case the debuginfod instance is killed, and we try
- the next port.
-
- The test-case only uses the v4 address 127.0.0.1, so fix this by:
- - accepting "started http server on IPv4 port=$port"
- - rejecting "started http server on IPv6 port=$port"

- opcodes: Fix RPATH not being set for dynamic libbfd dependency
- If built as a shared library, libopcodes has a load-time dependency on
- libbfd, which is recorded in the dynamic section, however without a
- corresponding RPATH entry for the directory to find libbfd in. This
- causes loading to fail whenever libbfd is only pulled by libopcodes
- indirectly and libbfd has been installed in a directory that is not in
- the dynamic loader's search path.
-
- It does not happen with the programs included with binutils or GDB,
- because they all also pull libbfd when using libopcodes, but it can
- happen with external software, e.g.:
-
- $ gdbserver --help
- gdbserver: error while loading shared libraries: libbfd-[...].so: cannot open shared object file: No such file or directory
- $
-
- (not our `gdbserver').
-
- Indirect dynamic dependencies are handled by libtool automatically by
- adding RPATH entries as required, however our setup for libopcodes
- prevents this from happening by linking in libbfd with an explicit file
- reference sneaked through to the linker directly behind libtool's back
- via the `-Wl' linker command-line option rather than via `-l' combined
- with a suitable library search path specified via `-L', as it would be
- usually the case, or just referring to the relevant .la file in a fully
- libtool-enabled configuration such as ours.
-
- According to an observation in the discussion back in 2007[1][2][3] that
- has led to the current arrangement it is to prevent libtool from picking
- up the wrong version of libbfd. It does not appear to be needed though,
- not at least with our current libtool incarnation, as directly referring
- `libbfd.la' does exactly what it should, as previously suggested[4], and
- with no link-time reference to the installation directory other than to
- set RPATH. Uninstalled version of libopcodes has libbfd's build-time
- location prepended to RPATH too, as also expected.
-
- Use a direct reference to `libbfd.la' then, making the load error quoted
- above go away. Alternatively `-L' and `-l' could be used to the same
- effect, but it seems an unnecessary complication and just another way to
- circumvent rather than making use of libtool.

- gdb: change functions returning value contents to use gdb::array_view
- The bug fixed by this [1] patch was caused by an out-of-bounds access to
- a value's content. The code gets the value's content (just a pointer)
- and then indexes it with a non-sensical index.
-
- This made me think of changing functions that return value contents to
- return array_views instead of a plain pointer. This has the advantage
- that when GDB is built with _GLIBCXX_DEBUG, accesses to the array_view
- are checked, making bugs more apparent / easier to find.
-
- This patch changes the return types of these functions, and updates
- callers to call .data() on the result, meaning it's not changing
- anything in practice. Additional work will be needed (which can be done
- little by little) to make callers propagate the use of array_view and
- reap the benefits.

- warning (_("Blabla %s, blabla %s"),

- This doesn't work, because target_pid_to_str stores its result in a

- libctf, ld: handle nonrepresentable types better
- ctf_type_visit (used, among other things, by the type dumping code) was
- aborting when it saw a nonrepresentable type anywhere: even a single
- structure member with a nonrepresentable type caused an abort with
- ECTF_NONREPRESENTABLE. This is not useful behaviour, given that the
- abort comes from a type-resolution we are only doing in order to
- determine whether the type is a structure or union. We know
- nonrepresentable types can't be either, so handle that case and
- pass the nonrepresentable type down.
-
- (The added test verifies that the dumper now handles this case and
- prints nonrepresentable structure members as it already does
- nonrepresentable top-level types, rather than skipping the whole
- structure -- or, without the previous commit, skipping the whole types
- section.)

- binutils: make objdump/readelf --ctf-parent actually useful
- This option has been present since the very early days of the
- development of libctf as part of binutils, and it shows. Back in the
- earliest days, I thought we might handle ambiguous types by introducing
- new ELF sections on the fly named things like .ctf.foo.c for ambiguous
- types found only in foo.c, etc. This turned out to be a terrible idea,
- so we moved to using a CTF archive in the .ctf section which contained
- all the CTF dictionaries -- but the --ctf-parent option in objdump and
- readelf was never adjusted, and lingered as a mechanism to specify CTF
- parent dictionaries in sections other than .ctf, even though the linker
- has no way to produce parent dictionaries in different sections from
- their children, libctf's ctf_open can't handle such split-up
- parent/child dicts, and they are never found in the wild, emitted by GNU
- ld or by any known third-party linking tool.
-
- Meanwhile, the actually-useful ctf_link feature (albeit not used by ld)
- which lets you remap the names of CTF archive members (so you can end up
- with a parent archive member named something other than ".ctf", still
- contained with all its children in a single .ctf section) had no support
- in objdump or readelf: there was no way to tell them that these members
- were parents, so all the types in the associated child dicts always
- appeared corrupted, referencing nonexistent types from a parent objdump
- couldn't find.
-
- So adjust --ctf-parent so that rather than taking a section name it
- takes a member name instead (if not specified, the name is ".ctf", which
- is what GNU ld emits). Because the option was always useless before
- now, this is expected to have no backward-compatibility implications.
-
- As part of this, we have to slightly adjust the code which skips the
- archive member name if redundant: right now it skips it if it's ".ctf",
- on the assumption that this name will almost always be at the start
- of the objdump output and thus we'll end up with a shared dump
- and then smaller, headed dumps for the per-TU child dicts; but if
- the parent name has been changed, that won't be true any more.
-
- So change the rules to "members named .ctf which appear first in the
- first have their member name skipped". Since we now need to count
- members, move from ctf_archive_iter (for which passing in extra
- parameters requires defining a new struct and is clumsy) to
- ctf_archive_next, allowing us to just *call* dump_ctf_archive_member and
- maintain a member count in the obvious way. In the process we fix a
- tiny difference between readelf and objdump: if a ctf_dump ever failed,
- readelf skipped every later member, while objdump tried to keep going as
- much as it could. For a dumping tool the former is clearly preferable.

- binutils/ChangeLog
- 2021-10-25 Nick Alcock <nick.alcock@oracle.com>
-
- * objdump.c (usage): --ctf-parent now takes a name, not a section.
- (dump_ctf): Don't open a separate section; use the parent_name in
- ctf_dict_open instead. Use ctf_archive_next, not ctf_archive_iter,
- so we can pass down a member count.
- (dump_ctf_archive_member): Add the member count; don't return
- anything. Import parents into children no matter what the
- parent's name, while still avoiding displaying the header for the
- common parent name of ".ctf".
- * readelf.c (usage): Adjust similarly.
- (dump_section_as_ctf): Likewise.
- (dump_ctf_archive_member): Likewise. Never stop iterating over
- archive members, even if ctf_dump of one member fails.
- * doc/ctf.options.texi: Adjust.

- gdb/python: move gdb.Membuf support into a new file
- In a future commit I'm going to be creating gdb.Membuf objects from a
- new file within gdb/python/py*.c. Currently all gdb.Membuf objects
- are created directly within infpy_read_memory (as a result of calling
- gdb.Inferior.read_memory()).
-
- Initially I split out the Membuf creation code into a new function,
- and left the new function in gdb/python/py-inferior.c, however, it
- felt a little random that the Membuf creation code should live with
- the inferior handling code.
-
- So, then I moved all of the Membuf related code out into a new file,
- gdb/python/py-membuf.c, the interface is gdbpy_buffer_to_membuf, which
- wraps an array of bytes into a gdb.Membuf object.
-
- Most of the code is moved directly from py-inferior.c with only minor
- tweaks to layout and replacing NULL with nullptr, hence, I've left the
- copyright date on py-membuf.c as 2009-2021 to match py-inferior.c.
-
- Currently, the only user of this code is still py-inferior.c, but in
- later commits this will change.
-
- There should be no user visible changes after this commit.

- RISC-V: Added ld testcase for pcgp relaxation.
- Consider the the pcgp-relax-02 testcase,
-
- .text
- .globl _start
- _start:
- .L1: auipc a0, %pcrel_hi(data_a)
- .L2: auipc a1, %pcrel_hi(data_b)
- addi a0, a0, %pcrel_lo(.L1)
- addi a1, a1, %pcrel_lo(.L2)
-
- .data
- .word 0x0
- .globl data_a
- data_a:
- .word 0x1
-
- .section .rodata
- .globl data_b
- data_b:
- .word 0x2
-
- If the first auipc is deleted, but we are still building the pcgp
- table (connect the high and low pcrel relocations), then there is
- an aliasing issue that we need some way to disambiguate which of
- the two symbols we are targeting. Therefore, Palmer thought of a
- way to use R_RISCV_DELETE to split this into two phases, so we
- could resolve the addresses before creating the ambiguities.
-
- This patch just add the ld testcase for the above case, in case we
- have changed something but break this.

- RISC-V: Don't separate pcgp relaxation to another relax pass.
- Commit abd20cb637008da9d32018b4b03973e119388a0a and
- ebdcad3fddf6ec21f6d4dcc702379a12718cf0c4 introduced additional
- complexity into the paths run by the RISC-V relaxation pass in order to
- resolve the issue of accurately keeping track of pcrel_hi and pcrel_lo
- pairs. The first commit split up relaxation of these relocs into a pass
- which occurred after other relaxations in order to prevent the situation
- where bytes were deleted in between a pcrel_lo/pcrel_hi pair, inhibiting
- our ability to find the corresponding pcrel_hi relocation from the
- address attached to the pcrel_lo.
-
- Since the relaxation was split into two passes the 'again' parameter
- could not be used to perform the entire relaxation process again and so
- the second commit added a way to restart ldelf_map_segments, thus
- starting the whole process again.
-
- Unfortunately this process could not account for the fact that we were
- not finished with the relaxation process so in some cases - such as the
- case where code would not fit in a memory region before the
- R_RISCV_ALIGN relocation was relaxed - sanity checks in generic code
- would fail.
-
- This patch fixes all three of these concerns by reverting back to a
- system of having only one target relax pass but updating entries in the
- table of pcrel_hi/pcrel_lo relocs every time any bytes are deleted. Thus

- gdb, gdbserver: make target_waitstatus safe
- I stumbled on a bug caused by the fact that a code path read
- target_waitstatus::value::sig (expecting it to contain a gdb_signal
- value) while target_waitstatus::kind was TARGET_WAITKIND_FORKED. This
- meant that the active union field was in fact
- target_waitstatus::value::related_pid, and contained a ptid. The read
- signal value was therefore garbage, and that caused GDB to crash soon
- after. Or, since that GDB was built with ubsan, this nice error
- message:
-
- /home/simark/src/binutils-gdb/gdb/linux-nat.c:1271:12: runtime error: load of value 2686365, which is not a valid value for type 'gdb_signal'
-
- Despite being a large-ish change, I think it would be nice to make
- target_waitstatus safe against that kind of bug. As already done
- elsewhere (e.g. dynamic_prop), validate that the type of value read from
- the union matches what is supposed to be the active field.
-
- - Make the kind and value of target_waitstatus private.
- - Make the kind initialized to TARGET_WAITKIND_IGNORE on
- target_waitstatus construction. This is what most users appear to do
- explicitly.
- - Add setters, one for each kind. Each setter takes as a parameter the
- data associated to that kind, if any. This makes it impossible to
- forget to attach the associated data.
- - Add getters, one for each associated data type. Each getter
- validates that the data type fetched by the user matches the wait
- status kind.
- - Change "integer" to "exit_status", "related_pid" to "child_ptid",
- just because that's more precise terminology.
- - Fix all users.
-
- That last point is semi-mechanical. There are a lot of obvious changes,
- but some less obvious ones. For example, it's not possible to set the
- kind at some point and the associated data later, as some users did.
- But in any case, the intent of the code should not change in this patch.
-
- This was tested on x86-64 Linux (unix, native-gdbserver and
- native-extended-gdbserver boards). It was built-tested on x86-64
- FreeBSD, NetBSD, MinGW and macOS. The rest of the changes to native
- files was done as a best effort. If I forgot any place to update in
- these files, it should be easy to fix (unless the change happens to
- reveal an actual bug).

-
- Refactor code slightly in nat/aarch64-linux-hw-point.c (aarch64_linux_get_debug_reg_capacity)
- Since the two locations which check the debug arch are the same code currently, it is
- a good idea to factor it out to a new function and just use that function from

- [gdb/tui] Fix breakpoint display functionality
- In commit 81e6b8eb208 "Make tui-winsource not use breakpoint_chain", a loop
- body was transformed into a lambda function body:
- ...
- - for (bp = breakpoint_chain;
- - bp != NULL;
- - bp = bp->next)
- + iterate_over_breakpoints ([&] (breakpoint *bp) -> bool
- ...
- and consequently:
- - a continue was replaced by a return, and
- - a final return was added.
-
- Then in commit 240edef62f0 "gdb: remove iterate_over_breakpoints function", we
- transformed back to a loop body:
- ...
- - iterate_over_breakpoints ([&] (breakpoint *bp) -> bool
- + for (breakpoint *bp : all_breakpoints ())
- ...
- but without reverting the changes that introduced the two returns.
-
- Consequently, breakpoints no longer show up in the tui source window.
-
- Fix this by reverting the changes that introduced the two returns.

- Fix latent Ada bug when accessing field offsets
- The "add accessors for field (and call site) location" patch caused a
- gdb crash when running the internal AdaCore testsuite. This turned
- out to be a latent bug in ada-lang.c.
-
- The immediate cause of the bug is that find_struct_field
- unconditionally uses TYPE_FIELD_BITPOS. This causes an assert for a
- dynamic type.
-
- This patch fixes the problem by doing two things. First, it changes
- find_struct_field to use a dummy value for the field offset in the
- situation where the offset is not actually needed by the caller. This
- works because the offset isn't used in any other way -- only as a
- result.
-
- Second, this patch assures that calls to find_struct_field use a
- resolved type when the offset is needed. For
- value_tag_from_contents_and_address, this is done by resolving the
- type explicitly. In ada_value_struct_elt, this is done by passing
- nullptr for the out parameters when they are not needed (the second
- call in this function already uses a resolved type).
-
- Note that, while we believe the parent field probably can't occur at a
- variable offset, the patch still updates this code path, just in case.
-
- I've updated an existing test case to reproduce the crash.
- I'm checking this in.

- Re: PR27625, powerpc64 gold __tls_get_addr calls
- My previous PR27625 patch had a problem or two. For one, the error
- "__tls_get_addr call lacks marker reloc" on processing some calls
- before hitting a call without markers typically isn't seen. Instead a
- gold assertion fails. Either way it would be a hard error, which
- triggers on a file contained in libphobos.a when running the gcc
- testsuite. A warning isn't even appropriate since the call involved
- is one built by hand without any of the arg setup relocations that
- might result in linker optimisation.
-
- So this patch reverts most of commit 0af4fcc25dd5, instead entirely
- ignoring the problem of mis-optimising old-style __tls_get_addr calls
- without marker relocs. We can't handle them gracefully without
- another pass over relocations before decisions are made about GOT
- entries in Scan::global or Scan::local. That seems too costly, just
- to link object files from 2009. What's more, there doesn't seem to be
- any way to allow the libphobos explicit __tls_get_addr call, but not
- old TLS sequences without marker relocs. Examining instructions
- before the __tls_get_addr call is out of the question: program flow
- might reach the call via a branch. Putting an R_PPC64_TLSGD marker
- with zero sym on the call might be a solution, but current linkers
- will then merrily optimise away the call!

- [gdb/exp] Improve <error reading variable> message
- When printing a variable x in a subroutine foo:
- ...
- subroutine foo (x)
- integer(4) :: x (*)
- x(3) = 1
- end subroutine foo
- ...
- where x is an array with unknown bounds, we get:
- ...
- $ gdb -q -batch outputs/gdb.fortran/array-no-bounds/array-no-bounds \
- -ex "break foo" \
- -ex run \
- -ex "print x"
- Breakpoint 1 at 0x4005cf: file array-no-bounds.f90, line 18.
-
- Breakpoint 1, foo (x=...) at array-no-bounds.f90:18
- 18 x(3) = 1
- $1 = <error reading variable>
- ...
-
- Improve the error message by printing the details of the error, such that we
- have instead:
- ...
- $1 = <error reading variable: failed to get range bounds>
- ...
-
- This is a change in gdb/valprint.c, and grepping through the sources reveals

-
- gdb: improve error reporting from the disassembler
- If the libopcodes disassembler returns a negative value then this
- indicates that the disassembly failed for some reason. In disas.c, in
- the function gdb_disassembler::print_insn we can see how this is
- handled; when we get a negative value back, we call the memory_error
- function, which throws an exception.
-
- The problem here is that the address used in the memory_error call is
- gdb_disassembler::m_err_memaddr, which is set in
- gdb_disassembler::dis_asm_memory_error, which is called from within
- the libopcodes disassembler through the
- disassembler_info::memory_error_func callback.
-
- However, for this to work correctly, every time the libopcodes
- disassembler returns a negative value, the libopcodes disassembler
- must have first called the memory_error_func callback.
-
- My first plan was to make m_err_memaddr a gdb::optional, and assert
- that it always had a value prior to calling memory_error, however, a
- quick look in opcodes/*-dis.c shows that there _are_ cases where a
- negative value is returned without first calling the memory_error_func
- callback, for example in arc-dis.c and cris-dis.c.
-
- Now, I think that a good argument can be made that these disassemblers
- must therefore be broken, except for the case where we can't read
- memory, we should always be able to disassemble the memory contents to
- _something_, even if it's just '.word 0x....'. However, I certainly
- don't plan to go and fix all of the disassemblers.
-
- What I do propose to do then, is make m_err_memaddr a gdb::optional,
- but now, instead of always calling memory_error, I add a new path
- which just calls error complaining about an unknown error. This new
- path is only used if m_err_memaddr doesn't have a value (indicating
- that the memory_error_func callback was not called).
-
- To test this I just augmented one of the disassemblers to always
- return -1, before this patch I see this:
-
- Dump of assembler code for function main:
- 0x000101aa <+0>: Cannot access memory at address 0x0
-
- And after this commit I now see:
-
- Dump of assembler code for function main:
- 0x000101aa <+0>: unknown disassembler error (error = -1)
-
- This doesn't really help much, but that's because there's no way to
- report non memory errors out of the disasembler, because, it was not
- expected that the disassembler would ever report non memory errors.

- [gdb/testsuite] Fix test name in gdb.python/python.exp
- When running test-case gdb.python/python.exp, we have:
- ...
- PASS: gdb.python/python.exp: starti via gdb.execute, not from tty
- PASS: gdb.python/python.exp: starti via interactive input
- ...
-
- The two tests are instances of the same test, with different values for
- starti command argument from_tty, so it's strange that the test names are so
- different.
-
- This is due to using a gdb_test nested in a gdb_test_multiple, with the inner
- one using a different test name than the outer one. [ That could still make
- sense if both produced passes, but that's not the case here. ]
-
- Fix this by using $gdb_test_name, such that we have:
- ...
- PASS: gdb.python/python.exp: starti via gdb.execute, not from tty
- PASS: gdb.python/python.exp: starti via gdb.execute, from tty

- ...
-
- As in commit a02a90c114c "[gdb/testsuite] Set sysroot earlier in
- local-board.exp", the problem is the use of -ex for
- "set auto-connect-native-target off", which makes that the last command to

-
- If we don't do it, GDB's register count won't consider registers contained
- in the XML but ignored by GDB, throwing the register numbering off.

- [ARM] Refactor some constants
- In preparation for the MVE extension patch, this one refactors some of
- the register-related constants we have for ARM.
-
- Basically I'm separating counting constants from numbering constants.
-
- For example, ARM_A1_REGNUM is a numbering constant, whereas ARM_NUM_ARG_REGS
- is a counting constant.

- [gdb/testsuite] Fix double debug info in gdb.dwarf2/dw2-ref-missing-frame.exp
- A mistake slipped in in commit a5ea23036d8 "[gdb/testsuite] Use function_range

-
- Before the commit the main file was compiled with debug info, and the two

- if {[prepare_for_testing_full "failed to prepare" \
- [list $testfile {} $srcfile {} $srcfuncfile {} \

-
- After the commit, all were compiled with debug info, and consequently, there
- are two versions of debug info for $srcfuncfile. This shows up as a FAIL when
- running the test-case with target boards readnow and cc-with-debug-names.
-
- Fix this by using prepare_for_testing_full, as before.

- When running test-case gdb.base/with-mf.exp with target board readnow, I run

- This is since commit 6010fb0c49e "[gdb/testsuite] Fix full buffer in

- Before that commit, the proc ensure_gdb_index would treat the line:

- [gdb] Make execute_command_to_string return string on throw
- The pattern for using execute_command_to_string is:
- ...
- std::string output;
- output = execute_fn_to_string (fn, term_out);
- ...
-
- This results in a problem when using it in a try/catch:
- ...
- try
- {
- output = execute_fn_to_string (fn, term_out)
- }
- catch (const gdb_exception &e)
- {
- /* Use output. */

-
- If an expection was thrown during execute_fn_to_string, then the output
- remains unassigned, while it could be worthwhile to known what output was
- generated by gdb before the expection was thrown.
-
- Fix this by returning the string using a parameter instead:

- [gdb/testsuite] Add check-readmore
- Consider the gdb output:
- ...
- 27 return SYSCALL_CANCEL (nanosleep, requested_time, remaining);^M
- (gdb) ^M
- Thread 2 "run-attach-whil" stopped.^M
- ...
-
- When trying to match the gdb prompt using gdb_test which uses '$gdb_prompt $',
- it may pass or fail.
-
- This sort of thing needs to be fixed (see commit b0e2f96b56b), but there's
- currently no way to reliably find this type of FAILs.
-
- We have check-read1, but that one actually make the test pass reliably.
-
- We need something like the opposite of check-read1: something that makes
- expect read a bit slower, or more exhaustively.
-
- Add a new test target check-readmore that implements this.
-
- There are two methods of implementing this in read1.c:
- - the first method waits a bit before doing a read
- - the second method does a read and then decides whether to
- return or to wait a bit and do another read, and so on.
-
- The second method is potentially faster, has less risc of timeout and could
- potentially detect more problems. The first method has a simpler
- implementation.
-
- The second method is enabled by default. The default waiting period is 10
- miliseconds.
-
- The first method can be enabled using:
- ...
- $ export READMORE_METHOD=1
- ...
- and the waiting period can be specified in miliseconds using:
- ...
- $ export READMORE_SLEEP=9
- ...
-
- Also a log file can be specified using:
- ...
- $ export READMORE_LOG=$(pwd -P)/LOG
- ...
-
- Tested on x86_64-linux.
-
- Testing with check-readmore showed these regressions:
- ...
- FAIL: gdb.base/bp-cmds-continue-ctrl-c.exp: run: stop with control-c (continue)
- FAIL: gdb.base/bp-cmds-continue-ctrl-c.exp: attach: stop with control-c (continue)
- ...
-
- I have not been able to find a problem in the test-case, and I think it's the
- nature of both the test-case and readmore that makes it run longer. Make
- these pass by increasing the alarm timeout from 60 to 120 seconds.

-
- gdb: add accessors for field (and call site) location
- Add accessors for the various location values in struct field. This
- lets us assert that when we get a location value of a certain kind (say,
- bitpos), the field's location indeed contains a value of that kind.
-
- Remove the SET_FIELD_* macros, instead use the new setters directly.
- Update the FIELD_* macros used to access field locations to go through
- the getters. They will be removed in a subsequent patch.
-
- There are places where the FIELD_* macros are used on call_site_target
- structures, because it contains members of the same name (loc_kind and
- loc). For now, I have replicated the getters/setters in
- call_site_target. But we could perhaps eventually factor them in a
- "location" structure that can be used at both places.
-
- Note that the field structure, being zero-initialized, defaults to a
- bitpos location with value 0. While writing this patch, I tried to make
- it default to an "unset" location, to catch places where we would miss
- setting a field's location. However, I found that some places relied on
- the default being "bitpos 0", so I left it as-is. This change could
- always be done as follow-up work, making these places explicitly set the
- "bitpos 0" location.
-
- I found two issues to fix:
-
- - I got some failures in the gdb.base/infcall-nested-structs-c++.exp
- test. They were caused by two functions in amd64-tdep.c using
- TYPE_FIELD_BITPOS before checking if the location is of the bitpos
- kind, which they do indirectly through `field_is_static`. Simply
- move getting the bitpos below the field_is_static call.
-
- - I got a failure in gdb.xml/tdesc-regs.exp. It turns out that in
- make_gdb_type_enum, we set enum field values using SET_FIELD_BITPOS,
- and later access them through FIELD_ENUMVAL. Fix that by using
- set_loc_enumval to set the value.

- PR28423, use-after-free in objdump
- XCOFF archives use a bi-directional linked list for file members. So
- one member points to both the previous member and the next member.
- Members may not be sequentially ordered in the file. This of course
- is over-engineered nonsense and an attractive target for fuzzers.
- (There is even a free list of members!) The testcase in PR28423 is an
- XCOFF archive with one member pointing to itself, which results in
- lots of bad behaviour. For example, "ar t" never terminates.
-
- The use-after-free with "objdump -r" happens like this: The first
- archive element is opened, its symbols are read and "canonicalized"
- for objdump, then relocations are read and printed. Those relocations
- use the canonicalized symbols, and also happen to be cached by the
- coff bfd backend support. objdump frees the symbols. The next
- archive element is then opened. This must be done before the first
- element is closed, because finding the next element uses data held in
- the currect element. Unfortunately the next element happens to be the
- original, so we aren't opening, we're reopening a bfd which has cached
- data. When the relocations are printed they use the cached copy
- containing references to the freed canonical symbols.
-
- This patch adds a little sanity checking to the XCOFF "open next
- archive file" support, so that it rejects archive members pointing at
- themselves. That is sufficient to cure this problem. Anything more
- is overkill. If someone deliberately fuzzes an XCOFF archive with an
- element loop then reports an "ar" bug when it runs forever, they will
- find their bug report closed WONTFIX.

- [gdb/testsuite] Make tui testing less verbose
- Currently, tui testing is rather verbose. When using these RUNTESTFLAGS to
- pick up all tui tests (17 in total):
- ...
- rtf=$(echo $(cd src/gdb/testsuite/; find gdb.* -type f -name *.exp* \
- | xargs grep -l tuiterm_env) )
- ...
- we have:
- ...
- $ wc -l gdb.log
- 120592 gdb.log
- ...
-
- Most of the output is related to controlling the tui screen, but that does
- not give a top-level sense of how the test-case progresses.
-
- Put differently: a lot of bandwith is used to describe how we arrive at a
- certain tui screen state. But we don't actually always show the state we
- arrive at, unless there's a FAIL.
-
- And if there's say, a PASS that should actually be FAILing, it's hard to
- detect.
-
- Fix this by:
- - dropping the -log on the call to verbose in _log. We still can get the
- same info back using runtest -v.
- - dumping the screen or box that we're checking, also when the test passes.
-
- Brings down verbosity to something more reasonable:

- gdb: Remove deprecated assertion in setting::get
- The commit 702991711a91bd47b209289562843a11e7009396 (gdb: Have setter
- and getter callbacks for settings) makes it possible for a setting not
- to be backed by a memory buffer but use callback functions instead to
- retrieve or set the setting's value.
-
- An assertion was not properly updated to take into account that the
- m_var member (which points to a memory buffer, if used) might be nullptr
- if the setting uses callback functions. If the setting is backed by a
- memory buffer, the m_var has to be non nullptr, which is already checked
- before the pointer is dereferenced.

- This commit removes this assertion as it is not valid anymore.

-
- A new 'is_zero' flag is added so we can preserve the existing

- gdb/python: fix memory leak in python inferior code
- When a user creates a gdb.Inferior object for the first time a new
- Python object is created. This object is then cached within GDB's
- inferior object using the registry mechanism (see
- inferior_to_inferior_object in py-inferior.c, specifically the calls
- to inferior_data and set_inferior_data).
-
- The Python Reference to the gdb.Inferior object held within the real
- inferior object ensures that the reference count on the Python
- gdb.Inferior object never reaches zero while the GDB inferior object
- continues to exist.
-
- At the same time, the gdb.Inferior object maintains a C++ pointer back
- to GDB's real inferior object. We therefore end up with a system that
- looks like this:
-
- Python Reference
- |
- |
- .----------. | .--------------.
- | |------------------->| |
- | inferior | | gdb.Inferior |
- | |<-------------------| |
- '----------' | '--------------'
- |
- |
- C++ Pointer
-
- When GDB's inferior object is deleted (say the inferior exits) then
- py_free_inferior is called (thanks to the registry system), this
- function looks up the Python gdb.Inferior object and sets the C++
- pointer to nullptr and finally reduces the reference count on the
- Python gdb.Inferior object.
-
- If at this point the user still holds a reference to the Python
- gdb.Inferior object then nothing happens. However, the gdb.Inferior
- object is now in the non-valid state (see infpy_is_valid in
- py-inferior.c), but otherwise, everything is fine.
-
- However, if there are no further references to the Python gdb.Inferior
- object, or, once the user has given up all their references to the
- gdb.Inferior object, then infpy_dealloc is called.
-
- This function currently checks to see if the inferior pointer within
- the gdb.Inferior object is nullptr or not. If the pointer is nullptr
- then infpy_dealloc immediately returns.
-
- Only when the inferior point in the gdb.Inferior is not nullptr do
- we (a) set the gdb.Inferior reference inside GDB's inferior to
- nullptr, and (b) call the underlying Python tp_free function.
-
- There are a number things wrong here:
-
- 1. The Python gdb.Inferior reference within GDB's inferior object
- holds a reference count, thus, setting this reference to nullptr
- without first decrementing the reference count would leak a
- reference, however...
-
- 2. As GDB's inferior holds a reference then infpy_dealloc will never
- be called until GDB's inferior object is deleted. Deleting a GDB
- inferior ohject calls py_free_inferior, and so gives up the
- reference. At this point there is no longer a need to call
- set_inferior_data to set the field back to NULL, that field must
- have been cleared in order to get the reference count to zero, which
- means...
-
- 3. If we know that py_free_inferior must be called before
- infpy_dealloc, then we know that the inferior pointer in
- gdb.Inferior will always be nullptr when infpy_dealloc is called,
- this means that the call to the underlying tp_free function will
- always be skipped. Skipping this call will cause Python to leak the
- memory associated with the gdb.Inferior object, which is what we
- currently always do.
-
- Given all of the above, I assert that the C++ pointer within
- gdb.Inferior will always be nullptr when infpy_dealloc is called.
- That's what this patch does.
-
- I wrote a test for this issue making use of Pythons tracemalloc
- module, which allows us to spot this memory leak.

- gdb/python: add a new gdb_exiting event
- Add a new event, gdb.events.gdb_exiting, which is called once GDB
- decides it is going to exit.
-
- This event is not triggered in the case that GDB performs a hard
- abort, for example, when handling an internal error and the user
- decides to quit the debug session, or if GDB hits an unexpected,
- fatal, signal.
-
- This event is triggered if the user just types 'quit' at the command
- prompt, or if GDB is run with '-batch' and has processed all of the
- required commands.
-
- The new event type is gdb.GdbExitingEvent, and it has a single
- attribute exit_code, which is the value that GDB is about to exit
- with.
-
- The event is triggered before GDB starts dismantling any of its own
- internal state, so, my expectation is that most Python calls should
- work just fine at this point.
-
- When considering this functionality I wondered about using the
- 'atexit' Python module. However, this is triggered when the Python
- environment is shut down, which is done from a final cleanup. At
- this point we don't know for sure what other GDB state has already

- gdb/python: update events test to handle missing exit_code
- The test gdb.python/py-events.exp sets up a handler for the gdb.exited
- event. Unfortunately the handler is slightly broken, it assumes that
- the exit_code attribute will always be present. This is not always
- the case.
-
- In a later commit I am going to add more tests to py-events.exp test
- script, and in so doing I expose the bug in our handling of gdb.exited
- events.
-
- Just to be clear, GDB itself is fine, it is the test that is not
- written correctly according to the Python Events API.
-
- So, in this commit I fix the Python code in the test, and extend the
- test case to exercise more paths through the Python code.
-
- Additionally, I noticed that the gdb.exited event is used as an
- example in the documentation for how to write an event handler.
- Unfortunately the same bug that we had in our test was also present in
- the example code in the manual.
-
- So I've fixed that too.

- [gdb/build] Add CXX_DIALECT to CXX
- Say we use a gcc version that (while supporting c++11) does not support c++11
- by default, and needs an -std setting to enable it.
-
- If gdb would use the default AX_CXX_COMPILE_STDCXX from autoconf-archive, then
- we'd have:
- ...
- CXX="g++ -std=gnu++11"
- ...
-
- That mechanism however has the following problem (quoting from commit
- 0bcda685399):
- ...
- the top level Makefile passes CXX down to subdirs, and that overrides whatever
- gdb/Makefile may set CXX to. The result would be that a make invocation from
- the build/gdb/ directory would use "g++ -std=gnu++11" as expected, while a
- make invocation at the top level would not.
- ...
-
- Commit 0bcda685399 fixes this by using a custom AX_CXX_COMPILE_STDCXX which
- does:
- ...
- CXX=g++
- CXX_DIALECT=-std=gnu++11
- ...
-
- The problem reported in PR28318 is that using the custom instead of the
- default AX_CXX_COMPILE_STDCXX makes the configure test for std::thread
- support fail.
-
- We could simply add $CXX_DIALECT to the test for std::thread support, but
- that would have to be repeated for each added c++ support test.
-
- Instead, fix this by doing:
- ...
- CXX="g++ -std=gnu++11"
- CXX_DIALECT=-std=gnu++11
- ...
-
- This is somewhat awkward, since it results in -std=gnu++11 occuring twice in
- some situations:
- ...
- $ touch src/gdb/dwarf2/read.c
- $ ( cd build/gdb; make V=1 dwarf2/read.o )
- g++-4.8 -std=gnu++11 -x c++ -std=gnu++11 ...
- ...
-
- However, both settings are needed:
- - the switch in CXX for the std::thread tests (and other tests)
- - the switch in CXX_DIALECT so it can be appended in Makefiles, to
- counteract the fact that the top-level Makefile overrides CXX
-
- The code added in gdb/ax_cxx_compile_stdcxx.m4 is copied from the default
- AX_CXX_COMPILE_STDCXX from autoconf-archive.

-
- Breakpoint 1, 0x000055555555463e in foo (i=0, i@entry=<optimized out>, \
- j=2, j@entry=<optimized out>)
- ...
-
- So, what explains the difference? Noteworthy, this is a dwarf assembly
- test-case, with debug info for foo and bar, but not for main.
-
- In the first case:
- - we run to main
- - this does not trigger expanding debug info, because there's none for main
- - we set a breakpoint at foo
- - this triggers expanding debug info. Relocated addresses are used in
- call_site info (because the exec is started)
- - we continue to foo, and manage to find the call_site info
-
- In the second case:
- - we set a breakpoint at foo
- - this triggers expanding debug info. Unrelocated addresses are used in
- call_site info (because the exec is not started)
- - we run to foo
- - this triggers objfile_relocate1, but it doesn't update the call_site
- info addresses
- - we don't manage to find the call_site info
-
- We could fix this by adding the missing call_site relocation in
- objfile_relocate1.
-
- This solution however is counter-trend in the sense that we're trying to
- work towards the situation where when starting two instances of an executable,
- we need only one instance of debug information, implying the use of
- unrelocated addresses.
-
- So, fix this instead by using unrelocated addresses in call_site info.

- [gdb/symtab] Add call_site_eq and call_site_hash
- In commit b4c919f7525 "[gdb/symtab] Fix htab_find_slot call in
- read_call_site_scope" , I removed the comment:
- ...
- It must be the first field as we overload core_addr_hash and core_addr_eq for
- it.
- ...
- for field pc of struct call_site.
-
- However, this was not tested, and when indeed moving field pc to the second
- location, we run into a testsuite failure in gdb.trace/entry-values.exp.
-
- This is caused by core_addr_eq (the eq_f function for the htab) being
- called with a pointer to the pc field (as passed into htab_find_slot) and a
- pointer to a hash table element. Now that pc is no longer the first field,
- the pointer to hash table element no longer points to the pc field.
-
- This could be fixed by simply reinstating the comment, but we're trying to
- get rid of this kind of tricks that make refactoring more difficult.
-
- Instead, fix this by:
- - reverting commit b4c919f7525, apart from the comment removal, such that
- we're passing a pointer to element to htab_find_slot
- - updating the htab_find_slot call in compunit_symtab::find_call_site
- in a similar manner
- - adding a call_site_eq and call_site_hash, and using these in the hash table
- instead of core_addr_eq and core_addr_hash.
-
- Tested on x86_64-linux, both with and without a trigger patch that moves pc to
- the second location in struct call_site.

- gdbsupport: remove attempt to define TARGET_WORD_SIZE
- In the gdbsupport configure.ac file, there is an attempt to define
- TARGET_WORD_SIZE. This is done by running grep on the file
- ../bfd/bfd-in3.h.
-
- The problem with this is, the file bfd-in3.h is generated into the bfd
- build directory when bfd is configured, and there is no dependency
- between the gdbsupport module and the bfd module, so, for example, if
- I do:
-
- $ ../src/configure
- $ make all-gdbsupport
-
- Then bfd will neither be configured, or built. In this case
- TARGET_WORD_SIZE ends up being defined, but with no value because the
- grep on bfd-in3.h fails.
-
- However, it turns out that this doesn't matter; we don't actually use
- TARGET_WORD_SIZE anywhere.
-
- My proposal in this commit is to just remove the definition of
- TARGET_WORD_SIZE, the alternative would be to add a dependency between
- configure-gdbsupport and configure-bfd into Makefile.def, but adding a
- dependency for something we don't need seems pretty pointless.

- gdb: Setting setter return a bool to tell if the value changed
- GDB can notify observers when a parameter is changed.
-
- To do that, do_set_command (in gdb/cli/cli-setshow.c) compares the new
- value against the old one before updating it, and based on that notifies
- observers. This looks like something like:
-
- int valuechanged = 0;
- switch (cmd->var.type ())
- {
- case var_integer:
- {
- LONGEST new_val = parse_and_eval_long (arg)
- if (new_val != cmd->var.get<int> ())
- {
- cmd->var.get<int> (new_val);
- value_changes = 1;
- }
- }
- case var_uinteger:
- case var_zuinteger:
- {
- unsigned int val
- = parse_cli_var_uinteger (c->var->type (), &arg, true);
- if (c->var->get<unsigned int> () != val)
- {
- c->var->set<unsigned int> (val);
- option_changed = true;
- }
- }
- case...
- /* And so on for all possible var_types. */
- }
-
- This comparison is done for each possible var_type, which leads to
- unnecessary logic duplication.
-
- In this patch I propose to move all those checks in one place within the
- setting setter method. This limits the code duplication and simplifies
- the do_set_command implementation.
-
- This patch also changes slightly the way a value change is detected.
- Instead of comparing the user provided value against the current value
- of the setting, we compare the value of the setting before and after the
- set operation. This is meant to handle edge cases where trying to set
- an unrecognized value would be equivalent to a noop (the actual value
- remains unchanged). Doing this requires that the original value needs
- to be copied before the update, which can be non trivial for
- std::string.
-
- There should be no user visible change introduced by this commit.
-
- Tested on x86_64 GNU/Linux.

- gdb: Have setter and getter callbacks for settings
- The main motivation behind this improvement is to help the
- implementation of a patch Simon Marchi is preparing to fix a bug when
- MI or Python try to access parameters that are inferior dependent (see
- PR/28085).
-
- This commit extends the previous ones, which introduces the setting
- object to represent a static variable whose value can be set or shown
- with the appropriate commands. This patch proposes that a setting can
- either contain a pointer to a static variable holding a setting, or
- pointers to a pair of setter and getter callback functions.
-
- The callbacks functions can be used to retrieve or change the value with
- custom logic. This is useful when the source of truth for a given
- setting is not contained in the variable pointed to by the setting
- instance.
-
- Given that the callback function call is hidden within the setting
- abstraction introduced earlier, none of the sites accessing the setting
- needs to be updated. The registered getter or setter is used whatever
- the way to access it is (through MI, Python, Guile, the "with" command
- and the $_gdb_setting / $_gdb_setting_str convenience functions).
-
- All the add_setshow_*_cmd are given a new overload that will accept the
- pair of function pointers (set / get functions) instead of the pointer
- to a global variable.
-
- Tested on GNU/Linux x86_64 with no regression observed.

-
- gdb: make string-like set show commands use std::string variable
- String-like settings (var_string, var_filename, var_optional_filename,
- var_string_noescape) currently take a pointer to a `char *` storage
- variable (typically global) that holds the setting's value. I'd like to
- "mordernize" this by changing them to use an std::string for storage.
-
- An obvious reason is that string operations on std::string are often
- easier to write than with C strings. And they avoid having to do any
- manual memory management.
-
- Another interesting reason is that, with `char *`, nullptr and an empty
- string often both have the same meaning of "no value". String settings
- are initially nullptr (unless initialized otherwise). But when doing
- "set foo" (where `foo` is a string setting), the setting now points to
- an empty string. For example, solib_search_path is nullptr at startup,
- but points to an empty string after doing "set solib-search-path". This
- leads to some code that needs to check for both to check for "no value".
- Or some code that converts back and forth between NULL and "" when
- getting or setting the value. I find this very error-prone, because it
- is very easy to forget one or the other. With std::string, we at least
- know that the variable is not "NULL". There is only one way of
- representing an empty string setting, that is with an empty string.
-
- I was wondering whether the distinction between NULL and "" would be
- important for some setting, but it doesn't seem so. If that ever
- happens, it would be more C++-y and self-descriptive to use
- optional<string> anyway.
-
- Actually, there's one spot where this distinction mattered, it's in
- init_history, for the test gdb.base/gdbinit-history.exp. init_history
- sets the history filename to the default ".gdb_history" if it sees that
- the setting was never set - if history_filename is nullptr. If
- history_filename is an empty string, it means the setting was explicitly
- cleared, so it leaves it as-is. With the change to std::string, this
- distinction doesn't exist anymore. This can be fixed by moving the code
- that chooses a good default value for history_filename to
- _initialize_top. This is ran before -ex commands are processed, so an
- -ex command can then clear that value if needed (what
- gdb.base/gdbinit-history.exp tests).
-
- Another small improvement, in my opinion is that we can now easily
- give string parameters initial values, by simply initializing the global
- variables, instead of xstrdup-ing it in the _initialize function.
-
- In Python and Guile, when registering a string-like parameter, we
- allocate (with new) an std::string that is owned by the param_smob (in
- Guile) and the parmpy_object (in Python) objects.
-
- This patch started by changing all relevant add_setshow_* commands to
- take an `std::string *` instead of a `char **` and fixing everything
- that failed to build. That includes of course all string setting
- variable and their uses.
-
- string_option_def now uses an std::string also, because there's a
- connection between options and settings (see
- add_setshow_cmds_for_options).
-
- The add_path function in source.c is really complex and twisted, I'd
- rather not try to change it to work on an std::string right now.
- Instead, I added an overload that copies the std:string to a `char *`
- and back. This means more copying, but this is not used in a hot path
- at all, so I think it is acceptable.

-
- gdb: Introduce setting construct within cmd_list_element
- cmd_list_element can contain a pointer to data that can be set and / or
- shown. This is achieved with the void* VAR member which points to the
- data that can be accessed, while the VAR_TYPE member (of type enum
- var_types) indicates how to interpret the data pointed to.
-
- With this pattern, the user of the cmd_list_element needs to know what
- is the storage type associated with a given VAR_TYPES in order to do
- the proper casting. No automatic safeguard is available to prevent
- miss-use of the pointer. Client code typically looks something like:
-
- switch (c->var_type)
- {
- case var_zuinteger:
- unsigned int v = *(unsigned int*) c->var;
- ...
- break;
- case var_boolean:
- bool v = *(bool *) c->var;
- ...
- break;
- ...
- }
-
- This patch proposes to add an abstraction around the var_types and void*
- pointer pair. The abstraction is meant to prevent the user from having
- to handle the cast and verify that the data is read or written as a type
- that is coherent with the setting's var_type. This is achieved by
- introducing the struct setting which exposes a set of templated get /
- set member functions. The template parameter is the type of the
- variable that holds the referred variable.
-
- Using those accessors allows runtime checks to be inserted in order to
- ensure that the data pointed to has the expected type. For example,
- instantiating the member functions with bool will yield something
- similar to:
-
- const bool &get<bool> () const
- {
- gdb_assert (m_var_type == var_boolean);
- gdb_assert (m_var != nullptr);
- return *static_cast<bool *> (m_var);
- }
- void set<bool> (const bool &var)
- {
- gdb_assert (m_var_type == var_boolean);
- gdb_assert (m_var != nullptr);
- *static_cast<bool *> (m_var) = var;
- }
-
- Using the new abstraction, our initial example becomes:
-
- switch (c->var_type)
- {
- case var_zuinteger:
- unsigned int v = c->var->get<unsigned int> ();
- ...
- break;
- case var_boolean:
- bool v = c->var->get<bool> ();
- ...
- break;
- ...
- }
-
- While the call site is still similar, the introduction of runtime checks
- help ensure correct usage of the data.
-
- In order to avoid turning the bulk of add_setshow_cmd_full into a
- templated function, and following a suggestion from Pedro Alves, a
- setting can be constructed from a pre validated type erased reference to
- a variable. This is what setting::erased_args is used for.
-
- Introducing an opaque abstraction to describe a setting will also make
- it possible to use callbacks to retrieve or set the value of the setting
- on the fly instead of pointing to a static chunk of memory. This will
- be done added in a later commit.
-
- Given that a cmd_list_element may or may not reference a setting, the
- VAR and VAR_TYPES members of the struct are replaced with a
- gdb::optional<setting> named VAR.
-
- Few internal function signatures have been modified to take into account
- this new abstraction:
-
- -The functions value_from_setting, str_value_from_setting and
- get_setshow_command_value_string used to have a 'cmd_list_element *'
- parameter but only used it for the VAR and VAR_TYPE member. They now
- take a 'const setting &' parameter instead.
- - Similarly, the 'void *' and a 'enum var_types' parameters of
- pascm_param_value and gdbpy_parameter_value have been replaced with a
- 'const setting &' parameter.
-
- No user visible change is expected after this patch.
-
- Tested on GNU/Linux x86_64, with no regression noticed.

- sim: filter out SIGSTKSZ [PR sim/28302]
- We map target signals to host signals so we can propagate signals
- between the host & simulated worlds. That means we need to know
- the symbolic names & values of all signals that might be sent.
-
- The tools that generate that list use signal.h and include all
- symbols that start with "SIG" so as to automatically include any
- new symbols that the C library might add. Unfortunately, this
- also picks up "SIGSTKSZ" which is not actually a signal itself,
- but a signal related setting -- it's the size of the stack when
- a signal is handled.
-
- By itself this doesn't super matter as we will never see a signal
- with that same value (since the range of valid signals tend to be
- way less than 1024, and the size of the default signal stack will
- never be that small). But with recent glibc changes that make this
- into a dynamic value instead of a compile-time constant, some users
- see build failures when building the sim.
-
- As suggested by Adam Sampson, update our scripts to ignore this
- symbol to simplify everything and avoid the build failure.

- gdb/testsuite/dwarf: don't define nested procs for rnglists/loclists
- When I wrote support for rnglists and loclists in the testsuite's DWARF
- assembler, I made it with nested procs, for example proc "table" inside
- proc "rnglists". The intention was that this proc "table" could only be
- used by the user while inside proc "rnglists"'s body. I had chosen very
- simple names, thinking there was no chance of name clashes. I recently
- learned that this is not how TCL works. This ends up defining a proc
- "table" in the current namespace ("Dwarf" in this case).
-
- Things still work if you generate rnglists and loclists in the same
- file, as each redefines its own procedures when executing. But if a
- user of the assembler happened to define a convenience "table" or
- "start_end" procedure, for example, it would get overriden.
-
- I'd like to change how this works to reduce the chances of a name clash.
-
- - Move the procs out of each other, so they are not defined in a nested
- fashion.
- - Prefix them with "_rnglists_" or "_loclists_".
- - While calling $body in the various procs, temporarily make the procs
- available under their "short" name. For example, while in rngllists'
- body, make _rnglists_table available as just "table". This allows
- existing code to keep working and keeps it not too verbose.
- - Modify with_override to allow the overriden proc to not exist. In
- that case, the temporary proc is deleted on exit.
-
- Note the non-conforming indentation when calling with_override in
- _loclists_list. This is on purpose: as we implement more loclists (and
- rnglists) entry types, the indentation would otherwise get larger and
- larger without much value for readability. So I think it's reasonable
- here to put them on the same level.

- gdb: add field::name / field::set_name
- Add the `name` and `set_name` methods on `struct field`, in order to
- remove `FIELD_NAME` and `TYPE_FIELD_NAME` macros. In this patch, the
- macros are changed to use `field::name`, so all the call sites that are
- used to set the field's name are changed to use `field::set_name`.
- The next patch will remove the macros completely.
-
- Note that because of the name clash between the existing field named
- `name` and the new method, I renamed the field `m_name`. It is not
- private per-se, because we can't make `struct field` a non-POD yet, but
- it should be considered private anyway (not accessed outside `struct
- field`).

- gdb/testsuite: make runto_main not pass no-message to runto
- As follow-up to this discussion:
-
- https://sourceware.org/pipermail/gdb-patches/2020-August/171385.html
-
- ... make runto_main not pass no-message to runto. This means that if we
- fail to run to main, for some reason, we'll emit a FAIL. This is the
- behavior we want the majority of (if not all) the time.
-
- Without this, we rely on tests logging a failure if runto_main fails,
- otherwise. They do so in a very inconsisteny mannet, sometimes using
- "fail", "unsupported" or "untested". The messages also vary widly.
- This patch removes all these messages as well.
-
- Also, remove a few "fail" where we call runto (and not runto_main). by
- default (without an explicit no-message argument), runto prints a
- failure already. In two places, gdb.multi/multi-re-run.exp and
- gdb.python/py-pp-registration.exp, remove "message" passed to runto.
- This removes a few PASSes that we don't care about (but FAILs will still
- be printed if we fail to run to where we want to). This aligns their
- behavior with the rest of the testsuite.

- gdbsupport: move gdb_file_up to its own file
- The following patches wants to change gdb_fopen_cloexec and
- gdb_mkostemp_cloexec to return a scoped_fd. Doing this causes a cyclic
- include between scoped_fd.h and filestuff.h, that both want to include
- each other. scoped_fd.h includes filestuff.h because of the
- scoped_fd::to_file method's return value. filestuff.h would then
- include scoped_fd.h for gdb_fopen_cloexec's and gdb_mkostemp_cloexec's
- return values.
-
- To fix that, move gdb_file_up to its own file, gdb_file.h.

- ld: pru: Fix resource_table output section alignment
- My commit 261980de18b added alignment for the resource table symbol.
- But it is wrong. The Linux remoteproc driver loads and interprets the
- contents of the .resource_table ELF section, not of a table symbol.
-
- Without this patch, if the linker happens to output padding for symbol
- alignment, then the resource table contents as viewed by the kernel
- loader would "shift" and look corrupted.

-
- If you look at the testcase's sources, you'll see that the intention
- is to resumes the program with "continue", wait to see a few of those
- "pid=..., count=..." lines, and then interrupt the program with
- Ctrl-C. But somehow, that resulted in GDB printing "Quit", instead of
- the Ctrl-C stopping the program with SIGINT.
-
- Here's what is happening:
-
- #1 - those "pid=..., count=..." lines we see above weren't actually
- output by the inferior after it has been continued (see #1).
- Note that "inf1_how" and "inf2_how" are "attach". What happened
- is that those "pid=..., count=..." lines were output by the
- inferiors _before_ they were attached to. We see them at that
- point instead of earlier, because that's where the testcase
- reads from the inferiors' spawn_ids.
-
- #2 - The testcase mistakenly thinks those "pid=..., count=..." lines
- happened after the continue was processed by GDB, meaning it has
- waited enough, and so sends the Ctrl-C. GDB hasn't yet passed
- the terminal to the inferior, so the Ctrl-C results in that
- Quit.
-
- The fix here is twofold:
-
- #1 - flush inferior output right after attaching
-
- #2 - consume the "Continuing" printed by "continue", indicating the
- inferior has the terminal. This is the same as done throughout
- the testsuite to handle this exact problem of sending Ctrl-C too
- soon.

- [gdb/testsuite] Disable vgdb tests if xml not supported
- I build gdb without xml support using --without-expat, and ran into:
- ...
- (gdb) target remote | vgdb --wait=2 --max-invoke-ms=2500 --pid=22032^M
- Remote debugging using | vgdb --wait=2 --max-invoke-ms=2500 --pid=22032^M
- relaying data between gdb and process 22032^M
- warning: Can not parse XML target description; XML support was disabled at \
- compile time^M
- ...
- (gdb) PASS: gdb.base/valgrind-infcall.exp: continue #1
- p gdb_test_infcall ()^M
- Remote 'g' packet reply is too long (expected 560 bytes, got 800 bytes): ...^M
- (gdb) FAIL: gdb.base/valgrind-infcall.exp: p gdb_test_infcall ()
- ...
-
- After googling the error message with context valgrind gdbserver, I found
- indications that the Remote 'g' packet reply error is due to missing xml
- support.
-
- And here ( https://www.valgrind.org/docs/manual/manual-core-adv.html ) I
- found:
- ...
- GDB version needed for ARM and PPC32/64.
-
- You must use a GDB version which is able to read XML target description sent
- by a gdbserver. This is the standard setup if GDB was configured and built
- with the "expat" library. If your GDB was not configured with XML support, it
- will report an error message when using the "target" command. Debugging will
- not work because GDB will then not be able to fetch the registers from the
- Valgrind gdbserver.
- ...
-
- So I guess I'm running into the same problem for x86_64.
-
- Fix this by skipping all gdb.base/valgrind-*.exp tests if xml support is not
- available. Although only the gdb.base/valgrind-infcall*.exp produce fails,
- the Remote 'g' packet reply error occurs in all tests, so it seems prudent to
- disable them all.
-
- Tested on x86_64-linux.

- [gdb/testsuite] Fix gdb.python/py-breakpoint.exp with python 2

-
- This is caused by the following:
- - a lambda function body needs to be an expression
- - in python 2, print is a statement, while in python 3 it's a function
- - a function call is an expression, and a statement is not.
-
- Fix this by defining a function print_bp_enabled:
- ...
- def print_bp_enabled (bp):
- print (bp.enabled)
- end
- ...
- and using that instead.

-
- The problem is that the regexp expects "hit Breakpoint $decimal". The "hit"

- show_thread_that_caused_stop returns true:
- ...
- int
- show_thread_that_caused_stop (void)

- gdb: enable target_async around stop_all_threads call in process_initial_stop_replies
- The following scenario hangs:
-
- - maint set target-non-stop on
- - `gdbserver --attach`
- - a multi-threaded program
-
- For example:
-
- Terminal 1:
-
- $ gnome-calculator&
- [1] 495731
- $ ../gdbserver/gdbserver --once --attach :1234 495731
- Attached; pid = 495731
- Listening on port 1234
-
- Terminal 2:
-
- $ ./gdb -nx -q --data-directory=data-directory /usr/bin/gnome-calculator -ex "maint set target-non-stop on" -ex "tar rem :1234"
- Reading symbols from /usr/bin/gnome-calculator...
- (No debugging symbols found in /usr/bin/gnome-calculator)
- Remote debugging using :1234
- * hangs *
-
- What happens is:
-
- - The protocol between gdb and gdbserver is in non-stop mode, but the
- user-visible behavior is all-stop
- - On connect, gdbserver sends one stop reply for one thread that is
- stops, the others stay running
- - In process_initial_stop_replies, gdb calls stop_all_threads to stop
- these other threads, because we are using the all-stop user-visible
- mode
- - stop_all_threads sends a stop request for all the running threads and
- then waits for resulting events
- - At this point, the remote target is in target_async(0) mode, which
- makes stop_all_threads not consider it for events
- - stop_all_threads loops indefinitely (it does not even block
- indefinitely, it is in an infinite busy loop) because there are no
- event sources. wait_one_event returns a TARGET_WAITKIND_NO_RESUMED
- wait status.
-
- Fix that by making the remote target async around the stop_all_threads
- call.
-
- I haven't implemented it because I'm not sure how to do it, but I think
- it would be a good idea to have, in stop_all_threads / wait_one /
- handle_one, an assert to check that if we are expecting one or more
- event, then there are some targets that are in a state where they can
- supply some events. Otherwise, we'll necessarily be stuck in this
- infinite loop, and it's probably due to a bug in GDB. I'm not too sure
- where to put this or how to express it though. Perhaps in
- stop_all_threads, here:
-
- for (int i = 0; i < waits_needed; i++)
- {
- wait_one_event event = wait_one ();
- *here*
- if (handle_one (event))
- break;
- }
-
- If at that point, the returned event is TARGET_WAITKIND_NO_RESUMED,
- there's a problem. We expect some event, because we've asked some
- threads to stop, but all targets are answering that they won't have any
- events for us. That's a contradiction, and a sign that something has
- gone wrong. It could perhaps event be:
-
- gdb_assert (event.ws.kind != TARGET_WAITKIND_NO_RESUMED);
-
- in handle_one, as the idea is the same in prepare_for_detach.
-
- A bit more sophisticated would be: we know which targets we are
- expecting waits from, since we know which threads we have asked to
- stop. So if any of these targets returns TARGET_WAITKIND_NO_RESUMED,
- something is fishy.
-
- Add a test that tests attaching with gdbserver's --attach flag to a
- multi-threaded program, and then connecting to it. Without the fix, the
- test reproduces the hang.

- gdb.base/foll-fork.exp: accept "info breakpoints" output in any order

-
- Since add_location_to_breakpoint uses only the address as a criterion to
- sort locations, the order of locations at the same address is not
- stable: it will depend on the insertion order. Here, the insertion
- order comes from the order of SALs when creating the breakpoint, which
- can vary from machine to machine. While it would be more user-friendly
- to have a more stable order for printed breakpoint locations, it doesn't
- really matter for this test, and it would be hard to define an order
- that will be the same everywhere, all the time.
-
- So, loosen the regexp to accept "inf 1" and "inf 2" in any order.

- gdb: print backtrace for internal error/warning
- This commit builds on previous work to allow GDB to print a backtrace
- of itself when GDB encounters an internal-error or internal-warning.
- This fixes PR gdb/26377.
-
- There's not many places where we call internal_warning, and I guess in
- most cases the user would probably continue their debug session. And
- so, in order to avoid cluttering up the output, by default, printing
- of a backtrace is off for internal-warnings.
-
- In contrast, printing of a backtrace is on by default for
- internal-errors, as I figure that in most cases hitting an
- internal-error is going to be the end of the debug session.
-
- Whether a backtrace is printed or not can be controlled with the new
- settings:
-
- maintenance set internal-error backtrace on|off
- maintenance show internal-error backtrace
-
- maintenance set internal-warning backtrace on|off
- maintenance show internal-warning backtrace
-
- Here is an example of what an internal-error now looks like with the
- backtrace included:
-
- (gdb) maintenance internal-error blah
- ../../src.dev-3/gdb/maint.c:82: internal-error: blah
- A problem internal to GDB has been detected,
- further debugging may prove unreliable.

- gdb: use libbacktrace to create a better backtrace for fatal signals
- GDB recently gained the ability to print a backtrace when a fatal
- signal is encountered. This backtrace is produced using the backtrace
- and backtrace_symbols_fd API available in glibc.
-
- However, in order for this API to actually map addresses to symbol
- names it is required that the application (GDB) be compiled with
- -rdynamic, which GDB is not by default.
-
- As a result, the backtrace produced often looks like this:
-
- Fatal signal: Bus error
- ----- Backtrace -----
- ./gdb/gdb[0x80ec00]
- ./gdb/gdb[0x80ed56]
- /lib64/libc.so.6(+0x3c6b0)[0x7fc2ce1936b0]
- /lib64/libc.so.6(__poll+0x4f)[0x7fc2ce24da5f]
- ./gdb/gdb[0x15495ba]
- ./gdb/gdb[0x15489b8]
- ./gdb/gdb[0x9b794d]
- ./gdb/gdb[0x9b7a6d]
- ./gdb/gdb[0x9b943b]
- ./gdb/gdb[0x9b94a1]
- ./gdb/gdb[0x4175dd]
- /lib64/libc.so.6(__libc_start_main+0xf3)[0x7fc2ce17e1a3]
- ./gdb/gdb[0x4174de]
- ---------------------
-
- This is OK if you have access to the exact same build of GDB, you can
- manually map the addresses back to symbols, however, it is next to
- useless if all you have is a backtrace copied into a bug report.
-
- GCC uses libbacktrace for printing a backtrace when it encounters an
- error. In recent commits I added this library into the binutils-gdb
- repository, and in this commit I allow this library to be used by
- GDB. Now (when GDB is compiled with debug information) the backtrace
- looks like this:
-
- ----- Backtrace -----
- 0x80ee08 gdb_internal_backtrace
- ../../src/gdb/event-top.c:989

- ---------------------
-
- Which seems much more useful.
-
- Use of libbacktrace is optional. If GDB is configured with
- --disable-libbacktrace then the libbacktrace directory will not be
- built, and GDB will not try to use this library. In this case GDB
- would try to use the old backtrace and backtrace_symbols_fd API.
-
- All of the functions related to writing the backtrace of GDB itself
- have been moved into the new files gdb/by-utils.{c,h}.

- Copy in libbacktrace from gcc
- This copies in libbacktrace from the gcc repository as it was in the
- commit 62e420293a293608f383d9b9c7f2debd666e9fc9. GDB is going to
- start using this library soon.
-
- A dependency between GDB and libbacktrace has already been added to
- the top level Makefile, so, after this commit, when building GDB,
- libbacktrace will be built first. However, libbacktrace is not yet
- linked into GDB, or used by GDB in any way.
-
- It is possible to stop libbacktrace being built by configuring the
- tree with --disable-libbacktrace.
-
- This commit does NOT update src-release.sh, that will be done in the
- next commit, this commit ONLY imports libbacktrace from gcc. This
- means that if you try to make a release of GDB from exactly this
- commit then the release tar file will not include libbacktrace.

- top-level configure: setup target_configdirs based on repository
- The top-level configure script is shared between the gcc repository
- and the binutils-gdb repository.
-
- The target_configdirs variable in the configure.ac script, defines
- sub-directories that contain components that should be built for the
- target using the target tools.
-
- Some components, e.g. zlib, are built as both host and target
- libraries.
-
- This causes problems for binutils-gdb. If we run 'make all' in the
- binutils-gdb repository we end up trying to build a target version of
- the zlib library, which requires the target compiler be available.
- Often the target compiler isn't immediately available, and so the
- build fails.
-
- The problem with zlib impacted a previous attempt to synchronise the
- top-level configure scripts from gcc to binutils-gdb, see this thread:
-
- https://sourceware.org/pipermail/binutils/2019-May/107094.html
-
- And I'm in the process of importing libbacktrace in to binutils-gdb,
- which is also a host and target library, and triggers the same issues.
-
- I believe that for binutils-gdb, at least at the moment, there are no
- target libraries that we need to build.
-
- In the configure script we build three lists of things we want to
- build, $configdirs, $build_configdirs, and $target_configdirs, we also
- build two lists of things we don't want to build, $skipdirs and
- $noconfigdirs. We then remove anything that is in the lists of things
- not to build, from the list of things that should be built.
-
- My proposal is to add everything in target_configdirs into skipdirs,
- if the source tree doesn't contain a gcc/ sub-directory. The result
- is that for binutils-gdb no target tools or libraries will be built,
- while for the gcc repository, nothing should change.
-
- If a user builds a unified source tree, then the target tools and
- libraries should still be built as the gcc/ directory will be present.
-
- I've tested a build of gcc on x86-64, and the same set of target
- libraries still seem to get built. On binutils-gdb this change
- resolves the issues with 'make all'.
-
- ChangeLog:
-
- * configure: Regenerate.
- * configure.ac (skipdirs): Add the contents of target_configdirs if
- we are not building gcc.

- sim: drop weak func attrs on module inits
- When I first wrote this, I was thinking we'd scan all source files
- that existed and generate a complete init list. That means for any
- particular build, we'd probably have a few functions that didn't
- exist, so weak attributes was necessary. What I ended up scanning
- though was only the source files that went into a particular build.
-
- There was another concern too: a source file might be included, but
- the build settings would cause all of its contents to be skipped
- (via CPP defines). So scanning via naive grep would pick up names
- not actually available. A check of the source tree shows that we
- never do this, and it's pretty easy to institute a policy that we
- don't start (by at the very least including a stub init func).
-
- The use of weak symbols ends up causing a problem in practice: for
- a few modules (like profiling), nothing else pulls it in, so the
- linker omits it entirely, which leads to the profiling module never
- being available. So drop the weak markings since we know all these
- funcs will be available.

- gdb: don't share aspace/pspace on fork with "detach-on-fork on" and "follow-fork-mode child"
- We found that when handling forks, two inferiors can unexpectedly share
- their program space and address space. To reproduce:
-
- 1. Using a test program that forks...
- 2. "set follow-fork-mode child"
- 3. "set detach-on-fork on" (the default)
- 4. run to a breakpoint somewhere after the fork
-
- Step 4 should have created a new inferior:
-
- (gdb) info inferiors
- Num Description Connection Executable
- 1 <null> /home/smarchi/build/wt/amd/gdb/fork
- * 2 process 251425 1 (native) /home/smarchi/build/wt/amd/gdb/fork
-
- By inspecting the state of GDB, we can see that the two inferiors now
- share one program space and one address space:
-
- Inferior 1:
-
- (top-gdb) p inferior_list.m_front.num
- $2 = 1
- (top-gdb) p inferior_list.m_front.aspace
- $3 = (struct address_space *) 0x5595e2520400
- (top-gdb) p inferior_list.m_front.pspace
- $4 = (struct program_space *) 0x5595e2520440
-
- Inferior 2:
-
- (top-gdb) p inferior_list.m_front.next.num
- $5 = 2
- (top-gdb) p inferior_list.m_front.next.aspace
- $6 = (struct address_space *) 0x5595e2520400
- (top-gdb) p inferior_list.m_front.next.pspace
- $7 = (struct program_space *) 0x5595e2520440
-
- You can then run inferior 1 again and the two inferiors will still
- erroneously share their spaces, but already at this point this is wrong.
-
- The cause of the bad {a,p}space sharing is in follow_fork_inferior.
- When following the child and detaching from the parent, we just re-use
- the parent's spaces, rather than cloning them. When we switch back to
- inferior 1 and run again, we find ourselves with two unrelated inferiors
- sharing spaces.
-
- Fix that by creating new spaces for the parent after having moved them
- to the child. My initial implementation created new spaces for the
- child instead. Doing this breaks doing "next" over fork(). When "next"
- start, we record the symtab of the starting location. When the program
- stops, we compare that symtab with the symtab the program has stopped
- at. If the symtab or the line number has changed, we conclude the
- "next" is done. If we create a new program space for the child and copy
- the parent's program space to it with clone_program_space, it creates
- new symtabs for the child as well. When the child stop, but still on
- the fork() line, GDB thinks the "next" is done because the symtab
- pointers no longer match. In reality they are two symtab instances that
- represent the same file. But moving the spaces to the child and
- creating new spaces for the parent, we avoid this problem.
-
- Note that the problem described above happens today with "detach-on-fork
- off" and "follow-fork-mode child", because we create new spaces for the
- child. This will have to be addressed later.
-
- Test-wise, improve gdb.base/foll-fork.exp to set a breakpoint that is
- expected to have a location in each inferiors. Without the fix, when
- the two inferiors erroneously share a program space, GDB reports a
- single location.

- libctf, lookup: fix bounds of pptrtab lookup
- An off-by-one bug in the check for pptrtab lookup meant that we could
- access the pptrtab past its bounds (*well* past its bounds),
- particularly if we called ctf_lookup_by_name in a child dict with "*foo"
- where "foo" is a type that exists in the parent but not the child and no
- previous lookups by name have been carried out. (Note that "*foo" is
- not even a valid thing to call ctf_lookup_by_name with: foo * is.
- Nonetheless, users sometimes do call ctf_lookup_by_name with invalid
- content, and it should return ECTF_NOTYPE, not crash.)
-
- ctf_pptrtab_len, as its name suggests (and as other tests of it in
- ctf-lookup.c confirm), is one higher than the maximum valid permissible
- index, so the comparison is wrong.

- libctf: fix handling of CTF symtypetab sections emitted by older GCC
- Older (pre-upstreaming) GCC emits a function symtypetab section of a
- format never read by any extant libctf. We can detect such CTF dicts by
- the lack of the CTF_F_NEWFUNCINFO flag in their header, and we do so
- when reading in the symtypetab section -- but if the set of symbols with
- types is sufficiently sparse, even an older GCC will emit a function
- index section.
-
- In NEWFUNCINFO-capable compilers, this section will always be the exact
- same length as the corresponding function section (each is an array of
- uint32_t, associated 1:1 with each other). But this is not true for the
- older compiler, for which the sections are different lengths. We check
- to see if the function symtypetab section and its index are the same
- length, but we fail to skip this check when this is not a NEWFUNCINFO
- dict, and emit a spurious corruption error for a CTF dict we could
- have perfectly well opened and used.
-
- Fix trivial: check the flag (and fix the terrible grammar of the error
- message at the same time).

- libtool.m4: fix nm BSD flag detection
- Libtool needs to get BSD-format (or MS-format) output out of the system
- nm, so that it can scan generated object files for symbol names for
- -export-symbols-regex support. Some nms need specific flags to turn on
- BSD-formatted output, so libtool checks for this in its AC_PATH_NM.
- Unfortunately the code to do this has a pair of interlocking flaws:
-
- - it runs the test by doing an nm of /dev/null. Some platforms
- reasonably refuse to do an nm on a device file, but before now this
- has only been worked around by assuming that the error message has a
- specific textual form emitted by Tru64 nm, and that getting this
- error means this is Tru64 nm and that nm -B would work to produce
- BSD-format output, even though the test never actually got anything
- but an error message out of nm -B. This is fixable by nm'ing *nm
- itself* (since we necessarily have a path to it).
-
- - the test is entirely skipped if NM is set in the environment, on the
- grounds that the user has overridden the test: but the user cannot
- reasonably be expected to know that libtool wants not only nm but
- also flags forcing BSD-format output. Worse yet, one such "user" is
- the top-level Cygnus configure script, which neither tests for
- nor specifies any BSD-format flags. So platforms needing BSD-format
- flags always fail to set them when run in a Cygnus tree, breaking
- -export-symbols-regex on such platforms. Libtool also needs to
- augment $LD on some platforms, but this is done unconditionally,
- augmenting whatever the user specified: the nm check should do the
- same.
-
- One wrinkle: if the user has overridden $NM, a path might have been
- provided: so we use the user-specified path if there was one, and
- otherwise do the path search as usual. (If the nm specified doesn't
- work, this might lead to a few extra pointless path searches -- but
- the test is going to fail anyway, so that's not a problem.)
-
- (Tested with NM unset, and set to nm, /usr/bin/nm, my-nm where my-nm is a
- symlink to /usr/bin/nm on the PATH, and /not-on-the-path/my-nm where
- *that* is a symlink to /usr/bin/nm.)

- libctf: link against libiberty before linking in libbfd or libctf-nobfd
- This ensures that the CTF_LIBADD, which always contains at least this
- when doing a shared link:
-
- -L`pwd`/../libiberty/pic -liberty
-
- appears in the link line before any requirements pulled in by libbfd.la,
- which include -liberty but because it is install-time do not include the
- -L`pwd`/../libiberty/pic portion (in an indirect dep like this, the path
- comes from the libbfd.la file, and is an install path). libiberty also
- appears after libbfd in the link line by virtue of libctf-nobfd.la,
- because libctf-nobfd has to follow libbfd in the link line, and that
- needs symbols from libiberty too.
-
- Without this, an installed liberty might well be pulled in by libbfd,
- and if --enable-install-libiberty is not specified this libiberty might
- be completely incompatible with what is being installed and break either
- or boht of libbfd and libctf. (The specific problem observed here is
- that bsearch_r was not present, but other problems might easily be
- observed in future too.)
-
- Because ld links against libctf, this has a tendency to break the system
- linker at install time too, if installing with --prefix=/usr. That's
- quite unpleasant to recover from.

- directories' and/or 'set substitute-path' a user can trick GDB into
- being unable to find the source files, but this feels like a rather
- crude way to solve the problem.
-
- In this commit a new option is add that stops GDB from opening and
- reading the source files. A user can run with source code reading
- disabled if this is required, then re-enable later if they decide
- that they now want to view the source code.

- gdb: remove duplicate cmd_list_element declarations
- For some reason we have two locations where cmd_list_elements are
- declared, cli/cli-cmds.h and gdbcmd.h. Worse still there is
- duplication between these two locations.
-
- In this commit I have moved all of the cmd_list_element declarations
- from gdbcmd.h into cli/cli-cmds.h and removed the duplicates.
-
- There should be no user visible changes after this commit.

- gdb: prevent an assertion when computing the frame_id for an inline frame
- I ran into this assertion while GDB was trying to unwind the stack:
-
- gdb/inline-frame.c:173: internal-error: void inline_frame_this_id(frame_info*, void**, frame_id*): Assertion `frame_id_p (*this_id)' failed.
-
- That is, when building the frame_id for an inline frame, GDB asks for
- the frame_id of the previous frame. Unfortunately, no valid frame_id
- was returned for the previous frame, and so the assertion triggers.
-
- What is happening is this, I had a stack that looked something like
- this (the arrows '->' point from caller to callee):
-
- normal_frame -> inline_frame
-
- However, for whatever reason (e.g. broken debug information, or
- corrupted stack contents in the inferior), when GDB tries to unwind
- "normal_frame", it ends up getting back effectively the same frame,
- thus the call stack looks like this to GDB:
-
- .-> normal_frame -> inline_frame
- | |
- '-----'
-
- Given such a situation we would expect GDB to terminate the stack with
- an error like this:
-
- Backtrace stopped: previous frame identical to this frame (corrupt stack?)
-
- However, the inline_frame causes a problem, and here's why:
-
- When unwinding we start from the sentinel frame and call
- get_prev_frame. We eventually end up in get_prev_frame_if_no_cycle,
- in here we create a raw frame, and as this is frame #0 we immediately
- return.
-
- However, eventually we will try to unwind the stack further. When we
- do this we inevitably needing to know the frame_id for frame #0, and
- so, eventually, we end up in compute_frame_id.
-
- In compute_frame_id we first find the right unwinder for this frame,
- in our case (i.e. for inline_frame) the $pc is within the function
- normal_frame, but also within a block associated with the inlined
- function inline_frame, as such the inline frame unwinder claims this
- frame.
-
- Back in compute_frame_id we next compute the frame_id, for our
- inline_frame this means a call to inline_frame_this_id.
-
- The ID of an inline frame is based on the id of the previous frame, so
- from inline_frame_this_id we call get_prev_frame_always, this
- eventually calls get_prev_frame_if_no_cycle again, which creates
- another raw frame and calls compute_frame_id (for frames other than
- frame 0 we immediately compute the frame_id).
-
- In compute_frame_id we again identify the correct unwinder for this
- frame. Our $pc is unchanged, however, the fact that the next frame is
- of type INLINE_FRAME prevents the inline frame unwinder from claiming
- this frame again, and so, the standard DWARF frame unwinder claims
- normal_frame.
-
- We return to compute_frame_id and call the standard DWARF function to
- build the frame_id for normal_frame.
-
- With the frame_id of normal_frame figured out we return to
- compute_frame_id, and then to get_prev_frame_if_no_cycle, where we add
- the ID for normal_frame into the frame_id cache, and return the frame
- back to inline_frame_this_id.
-
- From inline_frame_this_id we build a frame_id for inline_frame and
- return to compute_frame_id, and then to get_prev_frame_if_no_cycle,
- which adds the frame_id for inline_frame into the frame_id cache.
-
- So far, so good.
-
- However, as we are trying to unwind the complete stack, we eventually
- ask for the previous frame of normal_frame, remember, at this point
- GDB doesn't know the stack is corrupted (with a cycle), GDB still
- needs to figure that out.
-
- So, we eventually end up in get_prev_frame_if_no_cycle where we create
- a raw frame and call compute_frame_id, remember, this is for the frame
- before normal_frame.
-
- The first task for compute_frame_id is to find the unwinder for this
- frame, so all of the frame sniffers are tried in order, this includes
- the inline frame sniffer.
-
- The inline frame sniffer asks for the $pc, this request is sent up the
- stack to normal_frame, which, due to its cyclic behaviour, tells GDB
- that the $pc in the previous frame was the same as the $pc in
- normal_frame.
-
- GDB spots that this $pc corresponds to both the function normal_frame
- and also the inline function inline_frame. As the next frame is not
- an INLINE_FRAME then GDB figures that we have not yet built a frame to
- cover inline_frame, and so the inline sniffer claims this new frame.
- Our stack is now looking like this:
-
- inline_frame -> normal_frame -> inline_frame
-
- But, we have not yet computed the frame id for the outer most (on the
- left) inline_frame. After the frame sniffer has claimed the inline
- frame GDB returns to compute_frame_id and calls inline_frame_this_id.
-
- In here GDB calls get_prev_frame_always, which eventually ends up
- in get_prev_frame_if_no_cycle again, where we create a raw frame and
- call compute_frame_id.
-
- Just like before, compute_frame_id tries to find an unwinder for this
- new frame, it sees that the $pc is within both normal_frame and
- inline_frame, but the next frame is, again, an INLINE_FRAME, so, just
- like before the standard DWARF unwinder claims this frame. Back in
- compute_frame_id we again call the standard DWARF function to build
- the frame_id for this new copy of normal_frame.
-
- At this point the stack looks like this:
-
- normal_frame -> inline_frame -> normal_frame -> inline_frame
-
- After compute_frame_id we return to get_prev_frame_if_no_cycle, where
- we try to add the frame_id for the new normal_frame into the frame_id
- cache, however, unlike before, we fail to add this frame_id as it is
- a duplicate of the previous normal_frame frame_id. Having found a
- duplicate get_prev_frame_if_no_cycle unlinks the new frame from the
- stack, and returns nullptr, the stack now looks like this:
-
- inline_frame -> normal_frame -> inline_frame
-
- The nullptr result from get_prev_frame_if_no_cycle is fed back to
- inline_frame_this_id, which forwards this to get_frame_id, which
- immediately returns null_frame_id. As null_frame_id is not considered
- a valid frame_id, this is what triggers the assertion.
-
- In summary then:
-
- - inline_frame_this_id currently assumes that as the inline frame
- exists, we will always get a valid frame back from
- get_prev_frame_always,
-
- - get_prev_frame_if_no_cycle currently assumes that it is safe to
- return nullptr when it sees a cycle.
-
- Notice that in frame.c:compute_frame_id, this code:
-
- fi->this_id.value = outer_frame_id;
- fi->unwind->this_id (fi, &fi->prologue_cache, &fi->this_id.value);
- gdb_assert (frame_id_p (fi->this_id.value));
-
- The assertion makes it clear that the this_id function must always
- return a valid frame_id (e.g. null_frame_id is not a valid return
- value), and similarly in inline_frame.c:inline_frame_this_id this
- code:
-
- *this_id = get_frame_id (get_prev_frame_always (this_frame));
- /* snip comment */
- gdb_assert (frame_id_p (*this_id));
-
- Makes it clear that every inline frame expects to be able to get a
- previous frame, which will have a valid frame_id.
-
- As I have discussed above, these assumptions don't currently hold in
- all cases.
-
- One possibility would be to move the call to get_prev_frame_always
- forward from inline_frame_this_id to inline_frame_sniffer, however,
- this falls foul of (in frame.c:frame_cleanup_after_sniffer) this
- assertion:
-
- /* No sniffer should extend the frame chain; sniff based on what is
- already certain. */
- gdb_assert (!frame->prev_p);
-
- This assert prohibits any sniffer from trying to get the previous
- frame, as getting the previous frame is likely to depend on the next
- frame, I can understand why this assertion is a good thing, and I'm in
- no rush to alter this rule.
-
- The solution proposed here takes onboard feedback from both Pedro, and
- Simon (see the links below). The get_prev_frame_if_no_cycle function
- is renamed to get_prev_frame_maybe_check_cycle, and will now not do
- cycle detection for inline frames, even when we spot a duplicate frame
- it is still returned. This is fine, as, if the normal frame has a
- duplicate frame-id then the inline frame will also have a duplicate
- frame-id. And so, when we reject the inline frame, the duplicate
- normal frame, which is previous to the inline frame, will also be
- rejected.
-
- In inline-frame.c the call to get_prev_frame_always is no longer
- nested inside the call to get_frame_id. There are reasons why
- get_prev_frame_always can return nullptr, for example, if there is a
- memory error while trying to get the previous frame, if this should
- happen then we now give a more informative error message.

- Fix handling of DW_AT_data_bit_offset
- A newer version of GCC will now emit member locations using just
- DW_AT_data_bit_offset, like:
-
- <3><14fe>: Abbrev Number: 1 (DW_TAG_member)
- <14ff> DW_AT_name : (indirect string, offset: 0x215e): nb_bytes
- <1503> DW_AT_decl_file : 1
- <1503> DW_AT_decl_line : 10
- <1504> DW_AT_decl_column : 7
- <1505> DW_AT_type : <0x150b>
- <1509> DW_AT_bit_size : 31
- <150a> DW_AT_data_bit_offset: 64
-
- whereas earlier versions would emit something like:
-
- <3><164f>: Abbrev Number: 7 (DW_TAG_member)
- <1650> DW_AT_name : (indirect string, offset: 0x218d): nb_bytes
- <1654> DW_AT_decl_file : 1

- <165d> DW_AT_bit_offset : 1
- <165e> DW_AT_data_member_location: 8
-
- That is, DW_AT_data_member_location is not emitted any more. This is
- a change due to the switch to DWARF 5 by default.
-
- This change pointed out an existing bug in gdb, namely that the
- attr_to_dynamic_prop depends on the presence of
- DW_AT_data_member_location. This patch moves the handling of
- DW_AT_data_bit_offset into handle_data_member_location, and updates
- attr_to_dynamic_prop to handle this new case.
-
- A new test case is included. This test fails with GCC 11, but passes
- with an earlier version of GCC.

- [gdb/testsuite] Don't leave gdb instance running after function_range
- A typical dwarf assembly test-case start like this:
- ...
- standard_testfile .c -debug.S
-
- set asm_file [standard_output_file $srcfile2]
- Dwarf::assemble $asm_file {
- ...
- }
-
- if { [prepare_for_testing "failed to prepare" ${testfile} \
- [list $srcfile $asm_file] {nodebug}] } {
- return -1
- }
- ...
-
- When accidentally using build_for_executable instead of
- prepare_for_testing (or intentionally using it but forgetting to add
- clean_restart $binfile or some such) the mistake may not be caught, because
- another gdb instance is still running, and we may silently end up testing
- compiler-generated DWARF.
-
- This can be caused by something relatively obvious, like an earlier
- prepare_for_testing or clean_restart, but also by something more obscure like
- function_range, which may even be triggered by dwarf assembly like this:
- ...
- {MACRO_AT_func {main}}
- ...
-
- Fix this by calling gdb_exit at the end of function_range.
-
- Also fix the fallout of that in test-case gdb.dwarf2/dw2-bad-elf.exp, where a

- that would:
- - do a prepare_for_testing with $srcfile (roughtly equivalent to what
- MACRO_AT_func does,
- - call function_range for all functions main and foo, without starting a
- new gdb instance
- - set corresponding variables at the call-site: main_start, main_len,
- main_end, foo_start, foo_len, foo_end.
- - get size for types int and void*

- [gdb/testsuite] Use pie instead of -fpie/-pie
- I noticed two test-cases where -fpie is used. Using the canonical pie option
- will usually get one -fPIE instead.
-
- That choice is justified here in gdb_compile:
- ...
- # For safety, use fPIE rather than fpie. On AArch64, m68k, PowerPC
- # and SPARC, fpie can cause compile errors due to the GOT exceeding
- # a maximum size. On other architectures the two flags are
- # identical (see the GCC manual). Note Debian9 and Ubuntu16.10
- # onwards default GCC to using fPIE. If you do require fpie, then
- # it can be set using the pie_flag.
- set flag "additional_flags=-fPIE"
- ...
-
- There is no indication that using -fpie rather than -fPIE is on purpose, so
- use pie instead.

- [gdb/testsuite] Add gdb.testsuite/dump-system-info.exp
- When interpreting the testsuite results, it's often relevant what kind of
- machine the testsuite ran on. On a local machine one can just do
- /proc/cpuinfo, but in case of running tests using a remote system
- that distributes test runs to other remote systems that are not directly
- accessible, that's not possible.
-
- Fix this by dumping /proc/cpuinfo into the gdb.log, as well as lsb_release -a
- and uname -a.
-
- We could do this at the start of each test run, by putting it into unix.exp
- or some such. However, this might be too verbose, so we choose to put it into
- its own test-case, such that it get triggered in a full testrun, but not when
- running one or a subset of tests.
-
- We put the test-case into the gdb.testsuite directory, which is currently the
- only place in the testsuite where we do not test gdb. [ Though perhaps this
- could be put into a new gdb.info directory, since the test-case doesn't
- actually test the testsuite. ]

- Test that frame info/IDs are stable/consistent
- This adds a testcase that tests that the unwinder produces consistent
- frame info and frame IDs by making sure that "info frame" shows the
- same result when stopped at a function (level == 0), compared to when
- we find the same frame in the stack at a level > 0.
-
- E.g., on x86-64, right after running to main, we see:
-
- (gdb) info frame
- Stack level 0, frame at 0x7fffffffd340:
- rip = 0x555555555168 in main (gdb.base/backtrace.c:41); saved rip = 0x7ffff7dd90b3
- source language c.
- Arglist at 0x7fffffffd330, args:
- Locals at 0x7fffffffd330, Previous frame's sp is 0x7fffffffd340
- Saved registers:
- rbp at 0x7fffffffd330, rip at 0x7fffffffd338
- (gdb)
-
- and then after continuing to a function called by main, and selecting
- the "main" frame again, we see:
-
- (gdb) info frame
- Stack level 3, frame at 0x7fffffffd340:
- rip = 0x555555555172 in main (gdb.base/backtrace.c:41); saved rip = 0x7ffff7dd90b3
- caller of frame at 0x7fffffffd330
- source language c.
- Arglist at 0x7fffffffd330, args:
- Locals at 0x7fffffffd330, Previous frame's sp is 0x7fffffffd340
- Saved registers:
- rbp at 0x7fffffffd330, rip at 0x7fffffffd338
- (gdb)
-
- The only differences should be in the stack level, the 'rip = '
- address, and the presence of the "caller of frame at" info. All the
- rest should be the same. If it isn't, it probably means that the
- frame base, the frame ID, etc. aren't stable & consistent.
-
- The testcase exercises both the DWARF and the heuristic unwinders,
- using "maint set dwarf unwinder on/off".
-
- Tested on {x86-64 -m64, x86-64 -m32, Aarch64, Power8} GNU/Linux.

- Change get_ada_task_ptid parameter type
- get_ada_task_ptid currently takes a 'long' as its 'thread' parameter
- type. However, on some platforms this is actually a pointer, and
- using 'long' can sometimes end up with the value being sign-extended.
- This sign extension can cause problems later, if the tid is then later
- used as an address again.
-
- This patch changes the parameter type to ULONGEST and updates all the
- uses. This approach preserves sign extension on the targets where it
- is apparently intended, while avoiding it on others.

- [gdb/testsuite] Handle supports_memtag in gdb.base/gdb-caching-proc.exp
- In test-case gdb.base/gdb-caching-proc.exp, we run all procs declared with
- gdb_caching_proc. Some of these require a gdb instance, some not.
-
- We could just do a clean_restart every time, but that would amount to 44 gdb
- restarts. We try to minimize this by doing this only for the few procs that
- need it, and hardcoding those in the test-case.
-
- For those procs, we do a clean_restart, execute the proc, and then do a
- gdb_exit, to make sure the gdb instance doesn't linger such that we detect
- procs that need a gdb instance but are not listed in the test-case.
-
- However, that doesn't work in the case of gnat_runtime_has_debug_info. This
- proc doesn't require a gdb instance because it starts its own. But it doesn't
- clean up the gdb instance, and since it's not listed, the test-case
- doesn't clean up the gdb instance eiter. Consequently, the proc
- supports_memtag (which should be listed, but isn't) uses the gdb instance
- started by gnat_runtime_has_debug_info rather than throwing an error. Well,
- unless gnat_runtime_has_debug_info fails before starting a gdb instance, in
- which case we do run into the error.
-
- Fix this by:
- - doing gdb_exit unconditionally
- - fixing the resulting error by adding supports_memtag in the test-case to
- the "needing gdb instance" list
-
- Tested on x86_64-linux.

- gdbsupport/gdb_proc_service.h: use decltype instead of typeof
- Bug 28341 shows that GDB fails to compile when built with -std=c++11.
- I don't know much about the use case, but according to the author of the
- bug:
-
- I encountered the scenario where CXX is set to "g++ -std=c++11" when
- I try to compile binutils under GCC as part of the GCC 3-stage
- compilation, which is common for building a cross-compiler.
-
- The author of the bug suggests using __typeof__ instead of typeof. But
- since we're using C++, we might as well use decltype, which is standard.
- This is what this patch does.
-
- The failure (and fix) can be observed by configuring GDB with CXX="g++
- -std=c++11":

- riscv: print .2byte or .4byte before an unknown instruction encoding
- When the RISC-V disassembler encounters an unknown instruction, it
- currently just prints the value of the bytes, like this:
-
- Dump of assembler code for function custom_insn:
- 0x00010132 <+0>: addi sp,sp,-16
- 0x00010134 <+2>: sw s0,12(sp)
- 0x00010136 <+4>: addi s0,sp,16
- 0x00010138 <+6>: 0x52018b
- 0x0001013c <+10>: 0x9c45
-
- My proposal, in this patch, is to change the behaviour to this:
-
- Dump of assembler code for function custom_insn:
- 0x00010132 <+0>: addi sp,sp,-16
- 0x00010134 <+2>: sw s0,12(sp)
- 0x00010136 <+4>: addi s0,sp,16
- 0x00010138 <+6>: .4byte 0x52018b
- 0x0001013c <+10>: .2byte 0x9c45
-
- Adding the .4byte and .2byte opcodes. The benefit that I see here is
- that in the patched version of the tools, the disassembler output can
- be fed back into the assembler and it should assemble to the same
- binary format. Before the patch, the disassembler output is invalid
- assembly.
-
- I've started a RISC-V specific test file under binutils so that I can
- add a test for this change.

- > FAIL: gdb.ada/interface.exp: print s (timeout)
- ...
-
- [ The FAIL doesn't reproduce with gcc 9.3.1. This difference in
- behaviour bisects to gcc commit d70ba0c10de.
-
- The FAIL with earlier gcc bisects to gdb commit ba8694b650b. ]
-
- The FAIL is caused by gcc generating this debug info describing a named
- artificial variable:
- ...
- <2><1204>: Abbrev Number: 31 (DW_TAG_variable)
- <1205> DW_AT_name : s.14
- <1209> DW_AT_type : <0x1213>
- <120d> DW_AT_artificial : 1
- <120d> DW_AT_location : 5 byte block: 91 e0 7d 23 18 \
- (DW_OP_fbreg: -288; DW_OP_plus_uconst: 24)
- ...
-
- An easy way to fix this would be to simply not put named artificial variables
- into the symbol table. However, that causes regressions for Ada. It relies
- on being able to get the value from such variables, using a named reference.
-
- Fix this instead by marking the symbol as artificial, and:
- - ignoring such symbols in ada_resolve_variable, which fixes the FAIL
- - ignoring such ada symbols in do_print_variable_and_value, which prevents
- them from showing up in "info locals"
-
- Note that a fix for the latter was submitted here (
- https://sourceware.org/pipermail/gdb-patches/2008-January/054994.html ), and
- this patch borrows from it.

- Tested on x86_64-linux.

- PR28149, debug info with wrong file association
- gcc-11 and gcc-12 pass -gdwarf-5 to gas, in order to prime gas for
- DWARF 5 level debug info. Unfortunately it seems there are cases
- where the compiler does not emit a .file or .loc dwarf debug directive
- before any machine instructions. (Note that the .file directive
- typically emitted as the first line of assembly output doesn't count as
- a dwarf debug directive. The dwarf .file has a file number before the
- file name string.)
-
- This patch delays allocation of file numbers for gas generated line
- debug info until the end of assembly, thus avoiding any clashes with
- compiler generated file numbers. Two fixes for test case source are

- [GOLD] Output_data_got tidy
- Some Output_data_got methods already have support for addends, but
- were implemented as separate methods. This removes unnecessary code
- duplication.
-
- Relobj::local_has_got_offset and others there get a similar treatment.
- Comments are removed since it should be obvious without a comment, and
- the existing comments are not precisely what the code does. For
- example, a local_has_got_offset call without an addend does not return
- whether the local symbol has *a* GOT offset of type GOT_TYPE, it
- returns whether there is a GOT entry of type GOT_TYPE for the symbol

- [GOLD] Remove addend from Local_got_entry_key

- RISC-V: Merged extension string tables and their version tables into one.
- There are two main reasons for this patch,
-
- * In the past we had two extension tables, one is used to record all
- supported extensions in bfd/elfxx-riscv.c, another is used to get the
- default extension versions in gas/config/tc-riscv.c. It is hard to
- maintain lots of tables in different files, but in fact we can merge
- them into just one table. Therefore, we now define many riscv_supported_std*
- tables, which record names and versions for all supported extensions.
- We not only use these tables to initialize the riscv_ext_order, but
- also use them to get the default versions of extensions, and decide if
- the extensions should be enbaled by default.
-
- * We add a new filed `default_enable' for the riscv_supported_std* tables,
- to decide if the extension should be enabled by default. For now if the
- `default_enable' field of the extension is set to EXT_DEFAULT, then we
- should enable the extension when the -march and elf architecture attributes
- are not set. In the future, I suppose the `default_enable' can be set
- to lots of EXT_<VENDOR>, each vendor can decide to open which extensions,
- when the target triple of vendor is chosen.
-
- The elf/linux regression tests of riscv-gnu-toolchain are passed.
-
- bfd/
- * elfnn-riscv.c (cpu-riscv.h): Removed sine it is included in
- bfd/elfxx-riscv.h.
- (riscv_merge_std_ext): Updated since the field of rpe is changed.
- * elfxx-riscv.c (cpu-riscv.h): Removed.
- (riscv_implicit_subsets): Added implicit extensions for g.
- (struct riscv_supported_ext): Used to be riscv_ext_version. Moved
- from gas/config/tc-riscv.c, and added new field `default_enable' to
- decide if the extension should be enabled by default.
- (EXT_DEFAULT): Defined for `default_enable' field.
- (riscv_supported_std_ext): It used to return the supported standard
- architecture string, but now we move ext_version_table from
- gas/config/tc-riscv.c to here, and rename it to riscv_supported_std_ext.
- Currently we not only use the table to initialize riscv_ext_order, but
- also get the default versions of extensions, and decide if the extensions
- should be enbaled by default.

- [Inferior 1 (process 31952) exited normally]^M
- (gdb) Quit^M
- ...
-
- The problem is that the sleep (300) call at the end of main is interrupted,
- which causes the inferior to exit before the ctrl-c can be send.
-
- This problem is described at "Interrupted System Calls" in the docs, and the
- suggested solution (using a sleep loop) indeed fixes the problem.
-
- Fix this instead using the more prevalent:
- ...
- alarm (300);
- ...
- while (1) sleep (1);
- ...
- which is roughly equivalent because the sleep is called at the end of main,
- but slightly better because it guards against hangs from the start rather than
- from the end of main.
-
- Likewise in gdb.base/watch_thread_num.exp.
-
- Likewise in gdb.btrace/enable-running.exp, but use the sleep loop there,
- because the sleep is not called at the end of main.
-
- Tested on x86_64-linux.

- Breakpoint 1 at 0x4004e4^M
- (gdb) FAIL: gdb.dwarf2/dw2-abs-hi-pc.exp: break hello
- ...
-
- The problem is that the CU and function both have an empty address range:
- ...
- <0><d2>: Abbrev Number: 1 (DW_TAG_compile_unit)
- <108> DW_AT_name : dw2-abs-hi-pc-hello.c

- ...
-
- The address ranges are set like this in dw2-abs-hi-pc-hello-dbg.S:
- ...
- .4byte .hello_start /* DW_AT_low_pc */
- .4byte .hello_end /* DW_AT_high_pc */
- ...
- where the labels refer to dw2-abs-hi-pc-hello.c:
- ...
- extern int v;
-
- asm (".hello_start: .globl .hello_start\n");
- void
- hello (void)
- {
- asm (".hello0: .globl .hello0\n");
- v++;
- asm (".hello1: .globl .hello1\n");
- }
- asm (".hello_end: .globl .hello_end\n");
- ...
-
- Using asm labels in global scope is a known source of problems, as explained
- in the comment of proc function_range in gdb/testsuite/lib/dwarf.exp.
-
- Fix this by using function_range instead.

- which have a hole at at [0x4004af,0x4004c1).
-
- However, the address map of the partial symtabs incorrectly maps addresses
- in the hole (such as 0x4004b6 in the backtrace) to the foo CU.

- The address map of the full symbol table of the foo CU however does not

- Compilation Unit @ offset 0x145:
- Compilation Unit @ offset 0x150:
- Compilation Unit @ offset 0x308:
- ...
- of which the ones at 0xc7 and 0x145 are dummy CUs (that is, they do not
- contain a single DIE), which were added by recent commit 5ef670d81fd
- "[gdb/testsuite] Add dummy start and end CUs in dwarf assembly".
-
- The .debug_names section contains this CU table:
- ...
- [ 0] 0x0
- [ 1] 0x2e
- [ 2] 0xa5
- [ 3] 0xd2
- [ 4] 0x150
- [ 5] 0x308
- [ 6] 0x1
- [ 7] 0x0
- ...
- The last two entries are incorrect, and the entries for the dummy CUs are
- missing.
-
- The last two entries are incorrect because here in write_debug_names we write
- the dimension of the CU list as 8:
- ...
- /* comp_unit_count - The number of CUs in the CU list. */
- header.append_uint (4, dwarf5_byte_order,
- per_objfile->per_bfd->all_comp_units.size ()
- - per_objfile->per_bfd->tu_stats.nr_tus);
- ...
- while the actual dimension of the CU list is 6.
-
- The discrepancy is caused by this code which skips the dummy CUs:
- ...
- for (int i = 0; i < per_objfile->per_bfd->all_comp_units.size (); ++i)
- {
- ...
- /* CU of a shared file from 'dwz -m' may be unused by this main
- file. It may be referenced from a local scope but in such
- case it does not need to be present in .debug_names. */
- if (psymtab == NULL)
- continue;
- ...
- because they have a null partial symtab.
-
- We can fix this by writing the actual dimension of the CU list, but that still
- leaves the dummy CUs out of the CU list. The purpose of having these is to
- delimit the end of preceding CUs.
-
- So, fix this by:
- - removing the code that skips the dummy CUs (note that the same change
- was done for .gdb_index in commit efba5c2319d '[gdb/symtab] Handle PU
- without import in "save gdb-index"'.
- - verifying that all units are represented in the CU/TU lists
- - using the actual CU list size when writing the dimension of the CU list
- (and likewise for the TU list).

- This probably should have been ported long ago, but better late than
- never. We keep support for both versions for now since both projects
- tend to have long lifetimes. Maybe consider dropping SDL1 in another

- [gdb/tdep] Fix exec check in gdb_print_insn_arm
- With a gdb build with --enable-targets=all we run into a KFAIL:
- ...
- KFAIL: gdb.gdb/unittest.exp: executable loaded: maintenance selftest, \
- failed none (PRMS: gdb/27891)
- ...
- due to:
- ...
- Running selftest print_one_insn.^M
- Self test failed: arch armv8.1-m.main: self-test failed at \
- disasm-selftests.c:165^M
- ...
-
- The test fails because we expect disassembling of one arm insn to consume 4
- bytes and produce (using verbose = true in disasm-selftests.c):
- ...
- arm mov r0, #0
- ...
- but instead the disassembler uses thumb mode and only consumes 2
- bytes and produces:
- ...
- arm movs r0, r0
- ...
-
- The failure does not show up in the "no executable loaded" variant because
- this code in gdb_print_insn_arm isn't triggered:
- ...
- if (current_program_space->exec_bfd () != NULL)
- info->flags |= USER_SPECIFIED_MACHINE_TYPE;
- ...
- and consequently we do this in print_insn:
- ...
- if ((info->flags & USER_SPECIFIED_MACHINE_TYPE) == 0)
- info->mach = bfd_mach_arm_unknown;
- ...
- and don't set force_thumb to true in select_arm_features.
-
- The code in gdb_print_insn_arm makes the assumption that the disassembly
- architecture matches the exec architecture, which in this case is incorrect,
- because the exec architecture is x86_64, and the disassembly architecture is
- armv8.1-m.main. Fix that by explicitly checking it:
- ...
- if (current_program_space->exec_bfd () != NULL
- && (current_program_space->exec_bfd ()->arch_info
- == gdbarch_bfd_arch_info (gdbarch)))
- ...
-
- This fixes the print_one_insn failure, so remove the KFAIL.

- Tested on x86_64-linux.

- [gdb/tdep] Reset force_thumb in parse_arm_disassembler_options
- With a gdb build with --enable-targets=all, we have 2 arch-specific failures
- in selftest print_one_insn:
- ...
- $ gdb -q -batch a.out -ex "maint selftest print_one_insn" 2>&1 \

- disasm-selftests.c:165
- Self test failed: arch arm_any: self-test failed at disasm-selftests.c:165
- $
- ...
-
- During the first failed test, force_thumb is set to true, and remains so until
- and during the second test, which causes the second failure.
-
- Fix this by resetting force_thumb to false in parse_arm_disassembler_options,
- such that we get just one failure:
- ...
- $ gdb -q -batch a.out -ex "maint selftest print_one_insn" 2>&1 \

- Fix no-Python build

- This patch fixes the build by making test_python also be conditionally

- [gdb/testsuite] Set sysroot earlier in local-board.exp

- gdb/python: remove all uses of Py_TPFLAGS_HAVE_ITER
- Python 2 has a bit flag Py_TPFLAGS_HAVE_ITER which can be passed as
- part of the tp_flags field when defining a new object type. This flag
- is not defined in Python 3 and so we define it to 0 in
- python-internal.h (when IS_PY3K is defined).
-
- The meaning of this flag is that the object has the fields tp_iter and
- tp_iternext. Note the use of "has" here, the flag says nothing about
- the values in those fields, just that the type object has the fields.
-
- In early versions of Python 2 these fields were no part of the
- PyTypeObject struct, they were added in version 2.2 (see
- https://docs.python.org/release/2.3/api/type-structs.html). And so,
- there could be a some code compiled out there which has a PyTypeObject
- structure within it that doesn't even have the tp_iter and tp_iternext
- fields, attempting to access these fields would be undefined
- behaviour.
-
- And so Python added the Py_TPFLAGS_HAVE_ITER flag. If the flag is
- present then Python is free to access the tp_iter and tp_iternext
- fields.
-
- If we consider GDB then we always assume that the tp_iter and
- tp_iternext fields are part of PyTypeObject. If someone was crazy
- enough to try and compile GDB against Python 2.1 then we'd get lots of
- build errors saying that we were passing too many fields when
- initializing PyTypeObject structures. And so, I claim, we can be sure
- that GDB will always be compiled with a version of Python that has the
- tp_iter and tp_iternext fields in PyTypeObject.
-
- Next we can look at the Py_TPFLAGS_DEFAULT flag. In Python 2, each
- time additional fields are added to PyTypeObject a new Py_TPFLAGS_*
- flag would be defined to indicate whether those flags are present or
- not. And, those new flags would be added to Py_TPFLAGS_DEFAULT. And
- so, in the latest version of Python 2 the Py_TPFLAGS_DEFAULT flag
- includes Py_TPFLAGS_HAVE_ITER (see
- https://docs.python.org/2.7/c-api/typeobj.html).
-
- In GDB we pass Py_TPFLAGS_DEFAULT as part of the tp_flags for all
- objects we define.
-
- And so, in this commit, I propose to remove all uses of
- Py_TPFLAGS_HAVE_ITER from GDB, it's simply not needed.
-
- There should be no user visible changes after this commit.

- sim: accept -EB/-EL short options

- sim: dv-sockser: move sim-main.h include after system includes
- The sim-main.h header is a bit of a dumping ground. Every arch can
- (and many do) define all sorts of weird & common names that end up
- conflicting with system headers. So including it before the system
- headers sets us up for pain. v850 is a good example of this -- when
- building for mingw, we see weird failures:
-
- $ i686-w64-mingw32-gcc ... -c -o dv-sockser.o ../../../../sim/v850/../common/dv-sockser.c
- In file included from ../../../../sim/v850/sim-main.h:11,

-
- While gcc is unhelpful at first, running it through the preprocessor
- by hand shows more details:
-
- $ i686-w64-mingw32-gcc ... -E -dD -o dv-sockser.i ../../../../sim/v850/../common/dv-sockser.c

-
- This is because v850 sets up this common name:

- sim: mips: delete unused PSIZE define
- It's unclear what this define is for as it appears to be unused, and
- has never been used in the history of the mips sim. Delete it to tidy
- up, and to fix build errors for Windows targets that have a standard

- most sim files don't include many system headers, but enabling sockser
- code for mingw uncovers the conflict.
-
- Unfortunately the error produced by gcc is inscrutable, but running

-
- sim: ppc: enable -Wpointer-sign warnings
- When compiling with --enable-werror and CFLAGS="-O0 -g -Wall", we run into:
- ...
- src/sim/ppc/hw_memory.c: In function 'hw_memory_init_address':
- src/sim/ppc/hw_memory.c:204:7: error: pointer targets in passing argument 4 \
- of 'device_find_integer_array_property' differ in signedness \
- [-Werror=pointer-sign]
- &new_chunk->size);
- ^
- ...
-
- Fix these by adding an explicit pointer cast. It's a bit ugly to use APIs
- based on signed integers to read out unsigned values, but in practice, this
- is par for the course in the ppc code.
-
- We already use signed APIs and assign the result to unsigned values a lot:
- see how device_find_integer_property returns a signed integer (cell), but
- then assign it to unsigned types. The array APIs are not used that often
- which is why we don't see many warnings, and we disable warnings when we
- assign signed integers to unsigned integers in general.
-
- The dtc/libfdt project (which is the standard in other projects) processes
- the fdt blob as a series of bytes without any type information. Typing is
- left to the caller. They have core APIs that read/write bytes, and a few
- helper functions to cast/convert those bytes to the right value (e.g. u32).
- In this ppc sim code, the core APIs use signed integers, and the callers
- convert to unsigned, usually implicitly.
-
- We could add some core APIs to the ppc sim that deal with raw bytes and then
- add some helpers to convert to the right type, but that seems like a lot of
- lifting for what boils down to a cast, and is effectively equivalent to all
- the implicit assignments we use elsewhere. Long term, a lot of the ppc code
- should either get converted to existing sim common code, or we should stand
- up proper APIs in the common code first, or use standard libraries to do all
- the processing (e.g. libfdt). Either way, this device.c code would all get
- deleted, and callers (like these hw_*.c files) would get converted. Which
- is also why we go with a cast rather new (but largely unused) APIs.

- lot more work & conversions in the process, so going with the decl
- for now unblocks the warning unification.

- gdb: make thread_suspend_state::stop_pc optional
- Currently the stop_pc field of thread_suspect_state is a CORE_ADDR and
- when we want to indicate that there is no stop_pc available we set
- this field back to a special value.
-
- There are actually two special values used, in post_create_inferior
- the stop_pc is set to 0. This is a little unfortunate, there are
- plenty of embedded targets where 0 is a valid pc value. The more
- common special value for stop_pc though, is set in
- thread_info::set_executing, where the value (~(CORE_ADDR) 0) is used.
-
- This commit changes things so that the stop_pc is instead a
- gdb::optional. We can now explicitly reset the field to an
- uninitialised state, we also have asserts that we don't read the
- stop_pc when its in an uninitialised state (both in
- gdbsupport/gdb_optional.h, when compiling with _GLIBCXX_DEBUG
- defined, and in thread_info::stop_pc).
-
- One situation where a thread will not have a stop_pc value is when the
- thread is stopped as a consequence of GDB being in all stop mode, and
- some other thread stopped at an interesting event. When GDB brings
- all the other threads to a stop those other threads will not have a
- stop_pc set (thus avoiding an unnecessary read of the pc register).
-
- Previously, when GDB passed through handle_one (in infrun.c) the
- threads executing flag was set to false and the stop_pc field was left
- unchanged, i.e. it would (previous) have been left as ~0.
-
- Now, handle_one leaves the stop_pc with no value.
-
- This caused a problem when we later try to set these threads running
- again, in proceed() we compare the current pc with the cached stop_pc.
- If the thread was stopped via handle_one then the stop_pc would have
- been left as ~0, and the compare (in proceed) would (likely) fail.
- Now however, this compare tries to read the stop_pc when it has no
- value and this would trigger an assert.
-
- To resolve this I've added thread_info::stop_pc_p() which returns true
- if the thread has a cached stop_pc. We should only ever call
- thread_info::stop_pc() if we know that there is a cached stop_pc,
- however, this doesn't mean that every call to thread_info::stop_pc()
- needs to be guarded with a call to thread_info::stop_pc_p(), in most
- cases we know that the thread we are looking at stopped due to some
- interesting event in that thread, and so, we know that the stop_pc is
- valid.
-
- After running the testsuite I've seen no other situations where
- stop_pc is read uninitialised.
-
- There should be no user visible changes after this commit.

- [gdb/testsuite] Check avx support in gdb.arch/amd64-disp-step-avx.exp
- On a machine on Open Build Service I'm running into a SIGILL for test-case
- gdb.arch/amd64-disp-step-avx.exp:
- ...
- Program received signal SIGILL, Illegal instruction.^M
- test_rip_vex2 () at gdb.arch/amd64-disp-step-avx.S:40^M
- 40 vmovsd ro_var(%rip),%xmm0^M
- (gdb) FAIL: gdb.arch/amd64-disp-step-avx.exp: vex2: \
- continue to test_rip_vex2_end
- ...
- The SIGILL happens when trying to execute the first avx instruction in the
- executable.
-
- I can't directly access the machine, but looking at the log for test-case
- gdb.arch/i386-avx.exp, it seems that there's no avx support:
- ...
- Breakpoint 1, main (argc=1, argv=0x7fffffffd6b8) at gdb.arch/i386-avx.c:68^M
- 68 if (have_avx ())^M
- (gdb) print have_avx ()^M
- $1 = 0^M
- ...
-
- Fix this by:
- - adding a gdb_caching_proc have_avx, similar to have_mpx, using the have_avx
- function from gdb.arch/i386-avx.c
- - using proc have_avx in both gdb/testsuite/gdb.arch/amd64-disp-step-avx.exp
- and gdb/testsuite/gdb.arch/i386-avx.exp.
-
- Tested on my x86_64-linux laptop with avx support, where both test-cases pass.

- This patch fixes the problem by changing the return type. No other

- Test case reproducing PR28030 bug
- The original reproducer for PR28030 required use of a specific
- compiler version - gcc-c++-11.1.1-3.fc34 is mentioned in the PR,
- though it seems probable that other gcc versions might also be able to
- reproduce the bug as well. This commit introduces a test case which,
- using the DWARF assembler, provides a reproducer which is independent
- of the compiler version. (Well, it'll work with whatever compilers
- the DWARF assembler works with.)
-
- To the best of my knowledge, it's also the first test case which uses
- the DWARF assembler to provide debug info for a shared object. That
- being the case, I provided more than the usual commentary which should
- allow this case to be used as a template when a combo shared
- library / DWARF assembler test case is required in the future.
-
- I provide some details regarding the bug in a comment near the
- beginning of locexpr-dml.exp.
-
- This problem was difficult to reproduce; I found myself constantly
- referring to the backtrace while trying to figure out what (else) I
- might be missing while trying to create a reproducer. Below is a
- partial backtrace which I include for posterity.

- I'll note a few points regarding this backtrace:
-
- Frame #1 is where the internal error occurs. It's caused by an
- unhandled case for FIELD_LOC_KIND_DWARF_BLOCK. The fix for this bug
- adds support for this case.
-
- Frame #22 - it's a partial backtrace - shows that GDB is attempting to
- (re)run the program. You can see the exact command sequence that was
- used for reproducing this problem in the PR (at
- https://sourceware.org/bugzilla/show_bug.cgi?id=28030), but in a
- nutshell, after starting the program and advancing to the appropriate
- source line, GDB was asked to step into libstdc++; a "finish" command
- was issued, returning a value. The fact that a value was returned is
- very important. GDB was then used to step back into libstdc++. A
- breakpoint was set on a source line in the library after which a "run"
- command was issued.
-
- Frame #19 shows a call to objfile_purge_solibs. It's aptly named.
-
- Frame #7 is a call to the destructor for one of the objfile solibs; it
- turned out to be the one for libstdc++.
-
- Frames #6 thru #3 show various value preservation frames. If you look
- at preserve_values() in gdb/value.c, the value history is preserved
- first, followed by internal variables, followed by values for the
- extension languages (python and guile).

- CC_FOR_TARGET et al
- The top level Makefile, the ld Makefile and others, define
- CC_FOR_TARGET to be a compiler for the binutils target machine. This
- is the compiler that should be used for almost all tests with C
- source. There are _FOR_TARGET versions of CFLAGS, CXX, and CXXFLAGS
- too. This was all supposed to work with the testsuite .exp files
- using CC for the target compiler, and CC_FOR_HOST for the host
- compiler, with the makefiles passing CC=$CC_FOR_TARGET and
- CC_FOR_HOST=$CC to the runtest invocation.
-
- One exception to the rule of using CC_FOR_TARGET is the native-only ld
- bootstrap test, which uses the newly built ld to link a copy of
- itself. Since the files being linked were created with the host
- compiler, the boostrap test should use CC and CFLAGS, in case some
- host compiler option provides needed libraries automatically.
- However, bootstrap.exp used CC where it should have used CC_FOR_HOST.
- I set about fixing that problem, then decided that playing games in
- the makefiles with CC was a bad idea. Not only is it confusing, but
- other dejagnu code knows about CC_FOR_TARGET. See dejagnu/target.exp.
-
- So this patch gets rid of the makefile variable renaming and changes
- all the .exp files to use the correct _FOR_TARGET variables.
- CC_FOR_HOST and CFLAGS_FOR_HOST disappear. A followup patch will
- correct bootstrap.exp to use CFLAGS, and a number of other things I
- noticed.

- ...

- $build/gdb/testsuite.unix/outputs/gdb.dwarf2/fission-base/fission-base]^M
- ...
-
- The problem is that the executable refers to the dwo file using path name
- $build/gdb/testsuite.1/outputs/gdb.dwarf2/fission-base/fission-base.dwo,
- while the actual dwo file is at
- $build/gdb/testsuite.unix/outputs/gdb.dwarf2/fission-base/fission-base.dwo.
-
- This is caused by this trick in fission-base.S:
- ...
- #define XSTR(s) STR(s)
- #define STR(s) #s
- ...
- .asciz XSTR(DWO) # DW_AT_GNU_dwo_name
- ...
- and:
- ...
- $ echo | gcc -E -dD - | grep "define unix"
- ...
-
- I used this trick to avoid doing additional_flags=-DDWO=\"$dwo\", since I was
- concerned that there could be quoting issues.
-
- However, I've found other uses of this pattern, f.i. in
- gdb/testsuite/gdb.base/corefile-buildid.exp:
- ...
- additional_flags=-DSHLIB_NAME=\"$dlopen_lib\"]

- RISC-V: Extend .insn directive to support hardcode encoding.
- The .insn directive can let users use their own instructions, or
- some new instruction, which haven't supported in the old binutils.
- For example, if users want to use sifive cache instruction, they
- cannot just write "cflush.d1.l1" in the assembly code, they should
- use ".insn i SYSTEM, 0, x0, x10, -0x40". But the .insn directive
- may not easy to use for some cases, and not so friendly to users.
- Therefore, I believe most of the users will use ".word 0xfc050073",
- to encode the instructions directly, rather than use .insn. But
- once we have supported the mapping symbols, the .word directives
- are marked as data, so disassembler won't dump them as instructions
- as usual. I have discussed this with Kito many times, we all think
- extend the .insn direcitve to support the hardcode encoding, is the
- easiest way to resolve the problem. Therefore, there are two more
- .insn formats are proposed as follows,
-
- (original) .insn <type>, <operand1>, <operand2>, ...
- .insn <insn-length>, <value>
- .insn <value>
-
- The <type> is string, and the <insn-length> and <value> are constants.

- As a result, all callers of vfprintf_maybe_filtered now use gdbfmt, so

- symbols to decide whether we should dump data or instruction.

-
- * Use $d and $x to mark the distribution of data and instructions.
- Alignments of code are recognized as instructions, since we usually
- fill nops for them.
-
- * If the alignment have odd bytes, then we cannot just fill the nops
- into the spaces. We always fill an odd byte 0x00 at the start of
- the spaces. Therefore, add a $d mapping symbol for the odd byte,
- to tell disassembler that it isn't an instruction. The behavior
- is same as Arm and Aarch64.
-
- The elf/linux toolchain regressions all passed. Besides, I also
- disable the mapping symbols internally, but use the new objudmp, the
- regressions passed, too. Therefore, the new objudmp should dump
- the objects corretly, even if they don't have any mapping symbols.

- [gdb/testsuite] Improve argument syntax of proc arange
- The current syntax of proc arange is:
- ...
- proc arange { arange_start arange_length {comment ""} {seg_sel ""} } {
- ...
- and a typical call looks like:
- ...
- arange $start $len
- ...
-
- This style is somewhat annoying because if you want to specify the last
- parameter, you need to give the default values of all the other optional ones
- before as well:
- ...
- arange $start $len "" $seg_sel
- ...
-
- Update the syntax to:
- ...
- proc arange { options arange_start arange_length } {
- parse_options {
- { comment "" }
- { seg_sel "" }
- }
- ...
- such that a typical call looks like:
- ...
- arange {} $start $len
- ...
- and a call using seg_sel looks like:
- ...
- arange {
- seg_sel $seg_sel
- } $start $len
- ...
-
- Also update proc aranges, which already has an options argument, to use the
- new proc parse_options.

- [gdb/symtab] Don't write .gdb_index symbol table with empty entries
- When comparing the sizes of the index files generated for shlib
- outputs/gdb.dwarf2/dw2-zero-range/shr1.sl, I noticed a large difference
- between .debug_names:
- ...
- $ gdb -q -batch $shlib -ex "save gdb-index -dwarf-5 ."
- $ du -b -h shr1.sl.debug_names shr1.sl.debug_str
- 61 shr1.sl.debug_names

- $ gdb -q -batch $shlib -ex "save gdb-index ."
- $ du -b -h shr1.sl.gdb-index
- 8.2K shr1.sl.gdb-index
- ...
-
- The problem is that the .gdb_index contains a non-empty symbol table with only

- [gdb/testsuite] Generate .debug_aranges in gdb.dlang/watch-loc.exp
- Before commit 5ef670d81fd "[gdb/testsuite] Add dummy start and end CUs in
- dwarf assembly" we had in exec outputs/gdb.dlang/watch-loc/watch-loc a D
- compilation unit at offset 0xc7:
- ...
- Compilation Unit @ offset 0xc7:
- Length: 0x4c (32-bit)
- Version: 4
- Abbrev Offset: 0x64
- Pointer Size: 8
- <0><d2>: Abbrev Number: 2 (DW_TAG_compile_unit)
- <d3> DW_AT_language : 19 (D)
- ...
- with a corresponding .debug_aranges entry:
- ...
- Offset into .debug_info: 0xc7
- Pointer Size: 4
- Segment Size: 0
-
- Address Length
- 004004a7 0000000b
- 00000000 00000000
- ...
-
- After that commit we have a dummy CU at offset 0xc7 and the D compilation unit
- at offset 0xd2:
- ...
- Compilation Unit @ offset 0xc7:
- Length: 0x7 (32-bit)
- Version: 4
- Abbrev Offset: 0x64
- Pointer Size: 8
- Compilation Unit @ offset 0xd2:
- Length: 0x4c (32-bit)
- Version: 4
- Abbrev Offset: 0x65
- Pointer Size: 8
- <0><dd>: Abbrev Number: 2 (DW_TAG_compile_unit)
- <de> DW_AT_language : 19 (D)
- ...
- while the .debug_aranges entry still points to 0xc7.
-
- The problem is that the test-case uses a hack (quoting from
- commit 75f06e9dc59):
- ...
- [ Note: this is a non-trivial test-case. The file watch-loc-dw.S contains a
- .debug_info section, but not an .debug_aranges section or any actual code.
- The file watch-loc.c contains code and a .debug_aranges section, but no other
- debug section. So, the intent for the .debug_aranges section in watch-loc.c
- is to refer to a compilation unit in the .debug_info section in
- watch-loc-dw.S. ]
- ...
- and adding the dummy CU caused that hack to stop working.
-
- Fix this by moving the generation of .debug_aranges from watch-loc.c to
- watch-loc.exp, such that we have:
- ...
- Offset into .debug_info: 0xd2
- Pointer Size: 4
- Segment Size: 0
-
- Address Length
- 004004a7 0000000b

- [gdb/testsuite] Add label option to proc cu
- We can use current dwarf assembly infrastructure to declare a label that marks

- declare_labels header_start_cu_a
- _section ".debug_info"
- header_start_cu_a : cu {} {
- }
- _section ".debug_info"
- header_start_cu_b : cu {} {
- }
- ...
- on the condition that we switch to the .debug_info section before, which makes
- this style of use fragile.
-
- Another way to achieve the same is to use the label as generated by the cu
- proc itself:
- ...
- variable _cu_label
- cu {} {
- }
- set header_start_cu_a $_cu_label
- cu {} {
- }
- set header_start_cu_b $_cu_label
- ...
- but again that seems fragile given that adding a new CU inbetween will
- silently result in the wrong value for the label.
-
- Add a label option to proc cu such that we can simply do:
- ...
- cu { label header_start_cu_a } {
- }
- cu { label header_start_cu_b } {
- }

- Fix two regressions caused by CU / TU merging
- PR symtab/28160 and PR symtab/27893 concern GDB crashes in the test
- suite when using the "fission" target board. They are both caused by
- the patches that merge the list of CUs with the list of TUs (and to a
- lesser degree by the patches to share DWARF data across objfiles), and
- the underlying issue is the same: it turns out that reading a DWO can
- cause new type units to be created. This means that the list of
- dwarf2_per_cu_data objects depends on precisely which CUs have been
- expanded. However, because the type units can be created while
- expanding a CU means that the vector of CUs can expand while it is
- being iterated over -- a classic mistake. Also, because a TU can be
- added later, it means the resize_symtabs approach is incorrect.
-
- This patch fixes resize_symtabs by removing it, and having set_symtab
- resize the vector on demand. It fixes the iteration problem by
- introducing a safe (index-based) iterator and changing the relevant
- spots to use it.

- Fix a latent bug in dw2-ranges-overlap.exp
- dw2-ranges-overlap.exp creates a program where a psymtab has two
- address ranges, and a function without debug info whose address is
- between these two ranges. Then it sets a breakpoint on this function
- and runs to it, expecting that the language should remain "auto; c"
- when stopped.
-
- However, this test case also has a "main" function described (briefly)
- in the DWARF, and this function is given language C++. Also, a
- breakpoint stop sets the current language to the language that was
- used when setting the breakpoint.
-
- My new DWARF scanner decides that this "main" is the main program and
- sets the current language to C++ at startup, causing this test to
- fail.
-
- This patch fixes the test in a simple way, by introducing a new
- function that takes the place of "main" in the DWARF. I think this
- still exercises the original problem, but also avoids problems with my
- branch.
-
- It seemed safe to me to submit this separately.

- [gdb/testsuite] Use compiler-generated instead of gas-generated stabs
- The test-case gdb.dwarf2/dw2-ranges.exp is the only one in the gdb testsuite
- that uses gas-generated stabs.
-
- While the use seems natural alongside the use of gas-generated dwarf in the
- same test-case, there are a few known issues, filed on the gdb side as:
- - PR symtab/12497 - "stabs: PIE relocation does not work"
- - PR symtab/28221 - "[readnow, stabs] FAIL: gdb.dwarf2/dw2-ranges.exp: \
- info line func"
- and on the gas side as:
- - PR gas/28233 - "[gas, --gstabs] Generate stabs more similar to gcc"
-
- The test-case contains a KFAIL for PR12497, but it's outdated and fails to
- trigger.
-
- The intention of the test-case is to test gas-generated dwarf, and using
- gcc-generated stabs instead of gas-generated stabs works fine.
-
- Supporting compiler-generated stabs is already a corner-case for gdb, and
- there's no current commitment/incentive to support/workaround gas-generated
- stabs, which can be considered a corner-case of a corner-case.

- On openSUSE Leap 15.2 and Tumbleweed, the CU for hello.c is typically not the

- Fix register regression in DWARF evaluator
- On an internal test case, using an arm-elf target, commit ba5bc3e5a92
- ("Make DWARF evaluator return a single struct value") causes a
- regression. (It doesn't happen for any of the other cross targets
- that I test when importing upstream gdb.)
-
- I don't know if there's an upstream gdb test case showing the same
- problem... I can only really run native tests with dejagnu AFAIK.
-
- The failure manifests like this:
-
- Breakpoint 1, file_1.export_1 (param_1=<error reading variable: Unable to access DWARF register number 64>, str=...) at [...]/file_1.adb:5
-
- Whereas when it works it looks like:
-
- Breakpoint 1, file_1.export_1 (param_1=99.0, str=...) at [...]/file_1.adb:5
-
- The difference is that the new code uses the passed-in gdbarch,
- whereas the old code used the frame's gdbarch, when handling
- DWARF_VALUE_REGISTER.
-
- This patch restores the use of the frame's arch.

- Fix Ada regression due to DWARF expression series
- Commit 0579205aec4 ("Simplify dwarf_expr_context class interface")
- caused a regression in the internal AdaCore test suite. I didn't try
- to reproduce this with the GDB test suite, but the test is identical
- to gdb.dwarf2/dynarr-ptr.exp.
-
- The problem is that this change:
-
- case DW_OP_push_object_address:
- /* Return the address of the object we are currently observing. */
- - if (this->data_view.data () == nullptr
- - && this->obj_address == 0)
- + if (this->m_addr_info == nullptr)
-
- ... slightly changes the logic here. In particular, it's possible for
- the caller to pass in a non-NULL m_addr_info, but one that looks like:
-
- (top) p *this.m_addr_info
- $15 = {
- type = 0x29b7a70,
- valaddr = {
- m_array = 0x0,
- m_size = 0
- },
- addr = 0,
- next = 0x0
- }
-
- In this case, an additional check is needed. With the current code,
- what happens instead is that the computation computes an incorrect
- address -- but one that does not fail in read_memory, due to the
- precise memory map of the embedded target in question.
-
- This patch restores the old logic.

- PR28217, Syntax error when memory region contains a hyphen
- The saga of commit 40726f16a8d7 continues. This attacks the problem
- of switching between SCRIPT and EXPRESSION state lexing by removing
- the need to do so for phdrs like ":text". Instead {WILDCHAR}*
- matching, the reason why ":text" lexed as one token, is restricted to
- within the braces of a section or overlay statement. The new WILD
- lexer state is switched at the non-optional brace tokens, so
- ldlex_backup is no longer needed. I've also removed the BOTH state,
- which doesn't seem to be needed any more. Besides rules involving
- error reporting, there was just one place where SCRIPT appeared
- without BOTH, the {WILDCHAR}* rule, three where BOTH appears without
- SCRIPT for tokens that only need EXPRESSION state, and two where BOTH
- appears alongside INPUT_LIST. (Since I'm editing the wild and
- filename rules, removing BOTH and adding WILD can also be seen as
- renaming the old BOTH state to SCRIPT and renaming the old SCRIPT
- state to WILD with a reduced scope.)
-
- As a followup, I'll look at removing EXPRESSION state from some lexer
- rules that no longer need it due to this cleanup.

-
- As far as prologue analysis is concerned, the most interesting part is
- done at address 0x0000003ff7fc42ee (<+16>): 'sd ra,136(sp)'. This stores
- the RA (return address) register on the stack, which is the information
- we are looking for in order to identify the caller.
-
- In the current implementation of the prologue scanner, GDB stops when
- hitting 0x0000003ff7fc42e6 (<+8>) because it does not know what to do
- with the 'ld' instruction. GDB thinks it reached the end of the
- prologue but have not yet reached the important part, which explain
- GDB's inability to unwind past this point.
-
- The section of the prologue starting at <+4> until <+12> is used to load
- the stack canary[1], which will then be placed on the stack at <+36> at
- the end of the prologue.
-
- In order to have the prologue properly handled, this commit proposes to
- add support for the ld instruction in the RISC-V prologue scanner.
- I guess riscv32 would use lw in such situation so this patch also adds
- support for this instruction.
-
- With this patch applied, gdb is now able to unwind past pthread_join:
-
- (gdb) bt
- #0 0x0000003ff7fccd20 in __futex_abstimed_wait_common64 () from /lib/riscv64-linux-gnu/libpthread.so.0
- #1 0x0000003ff7fc43da in __pthread_clockjoin_ex () from /lib/riscv64-linux-gnu/libpthread.so.0

- #3 0x0000002aaaaaa8c4 in foo() ()
- #4 0x0000002aaaaaa8da in main ()
-
- I have had a look to see if I could reproduce this easily, but in my
- simple testcases using '-fstack-protector-all', the canary is loaded
- after the RA register is saved. I do not have a reliable way of
- generating a prologue similar to the problematic one so I forged one
- instead.
-
- The testsuite have been run on riscv64 ubuntu 21.01 with no regression
- observed.

- Improve forward progress test in python.exp
- The test steps into func2 and than does an up to get back to the previous
- frame. The test checks that the line number you are at after the up command
- is greater than the line where the function was called from. The
- assembly/codegen for the powerpc target includes a NOP after the
- branch-link.
-
- func2 (); /* Break at func2 call site. /

-
- The PC at the instruction following the branch-link is 0x10000698 which
- GDB.find_pc_line() maps to the same line number as the bl instruction.
- GDB did move past the branch-link location thus making forward progress.
-
- The following proposed fix adds an additional PC check to see if forward
- progress was made. The line test is changed from greater than to greater
- than or equal.

- Deprecate a.out support for NetBSD targets.
- As discussed previously, a.out support is now quite deprecated, and in
- some cases removed, in both Binutils itself and NetBSD, so this legacy
- default makes little sense. `netbsdelf*` and `netbsdaout*` still work
- allowing the user to be explicit about there choice. Additionally, the
- configure script warns about the change as Nick Clifton requested.
-
- One possible concern was the status of NetBSD on NS32K, where only a.out
- was supported. But per [1] NetBSD has removed support, and if it were to
- come back, it would be with ELF. The binutils implementation is
- therefore marked obsolete, per the instructions in the last message.
-
- With that patch and this one applied, I have confirmed the following:
-
- --target=i686-unknown-netbsd
- --target=i686-unknown-netbsdelf
- builds completely
-
- --target=i686-unknown-netbsdaout
- properly fails because target is deprecated.
-
- --target=vax-unknown-netbsdaout builds completely except for gas, where
- the target is deprecated.

- gdb: don't print backtrace when dumping core after an internal error
- Currently, when GDB hits an internal error, and the user selects to
- dump core, the recently added feature to write a backtrace to the
- console will kick in, and print a backtrace as well as dumping the
- core.
-
- This was certainly not my intention when adding the backtrace on fatal
- signal functionality, this feature was intended to produce a backtrace
- when GDB crashes due to some fatal signal, internal errors should have
- continued to behave as they did before, unchanged.
-
- In this commit I set the signal disposition of SIGABRT back to SIG_DFL
- just prior to the call to abort() that GDB uses to trigger the core
- dump, this prevents GDB reaching the code that writes the backtrace to
- the console.
-
- I've also added a test that checks we don't see a backtrace on the
- console after an internal error.

-
- gdb: register SIGBUS, SIGFPE, and SIGABRT handlers
- Register handlers for SIGBUS, SIGFPE, and SIGABRT. All of these
- signals are setup as fatal signals that will cause GDB to terminate.
- However, by passing these signals through the handle_fatal_signal
- function, a user can arrange to see a backtrace when GDB
- terminates (see maint set backtrace-on-fatal-signal).
-
- In normal use of GDB there should be no user visible changes after
- this commit. Only if GDB terminates with one of the above signals
- will GDB change slightly, potentially printing a backtrace before
- aborting.
-
- I've added new tests for SIGFPE, SIGBUS, and SIGABRT.
-
-2021-08-11 Andrew Burgess <andrew.burgess@embecosm.com>
-
- gdb: print backtrace on fatal SIGSEGV
- This commit adds a new maintenance feature, the ability to print
- a (limited) backtrace if GDB dies due to a fatal signal.
-
- The backtrace is produced using the backtrace and backtrace_symbols_fd
- functions which are declared in the execinfo.h header, and both of
- which are async signal safe. A configure check has been added to
- check for these features, if they are not available then the new code
- is not compiled into GDB and the backtrace will not be printed.
-
- The motivation for this new feature is to aid in debugging GDB in
- situations where GDB has crashed at a users site, but the user is
- reluctant to share core files, possibly due to concerns about what
- might be in the memory image within the core file. Such a user might
- be happy to share a simple backtrace that was written to stderr.
-
- The production of the backtrace is on by default, but can switched off
- using the new commands:
-
- maintenance set backtrace-on-fatal-signal on|off
- maintenance show backtrace-on-fatal-signal
-
- Right now, I have hooked this feature in to GDB's existing handling of
- SIGSEGV only, but this will be extended to more signals in a later
- commit.
-
- One additional change I have made in this commit is that, when we
- decide GDB should terminate due to the fatal signal, we now
- raise the same fatal signal rather than raising SIGABRT.
-
- Currently, this is only effecting our handling of SIGSEGV. So,
- previously, if GDB hit a SEGV then we would terminate GDB with a
- SIGABRT. After this commit we will terminate GDB with a SIGSEGV.
-
- This feels like an improvement to me, we should still get a core dump,
- but in many shells, the user will see a more specific message once GDB
- exits, in bash for example "Segmentation fault" rather than "Aborted".
-
- Finally then, here is an example of the output a user would see if GDB
- should hit an internal SIGSEGV:
-
- Fatal signal: Segmentation fault
- ----- Backtrace -----

- ---------------------
- A fatal error internal to GDB has been detected, further
- debugging is not possible. GDB will now terminate.
-
- This is a bug, please report it. For instructions, see:
- <https://www.gnu.org/software/gdb/bugs/>.
-
- Segmentation fault (core dumped)
-
- It is disappointing that backtrace_symbols_fd does not actually map
- the addresses back to symbols, this appears, in part, to be due to GDB
- not being built with -rdynamic as the manual page for
- backtrace_symbols_fd suggests, however, even when I do add -rdynamic
- to the build of GDB I only see symbols for some addresses.
-
- We could potentially look at alternative libraries to provide the
- backtrace (e.g. libunwind) however, the solution presented here, which
- is available as part of glibc is probably a good baseline from which
- we might improve things in future.

- gdb: rename async_init_signals to gdb_init_signals
- The async_init_signals has, for some time, dealt with async and sync
- signals, so removing the async prefix makes sense I think.
-
- Additionally, as pointed out by Pedro:
-
- .....
-
- The comments relating to SIGTRAP and SIGQUIT within this function are
- out of date.
-
- The comments for SIGTRAP talk about the signal disposition (SIG_IGN)
- being passed to the inferior, meaning the signal disposition being
- inherited by GDB's fork children. However, we now call
- restore_original_signals_state prior to forking, so the comment on
- SIGTRAP is redundant.
-
- The comments for SIGQUIT are similarly out of date, further, the
- comment on SIGQUIT talks about problems with BSD4.3 and vfork,
- however, we have not supported BSD4.3 for several years now.
-
- Given the above, it seems that changing the disposition of SIGTRAP is
- no longer needed, so I've deleted the signal() call for SIGTRAP.
-
- Finally, the header comment on the function now called
- gdb_init_signals was getting quite out of date, so I've updated it
- to (hopefully) better reflect reality.
-
- There should be no user visible change after this commit.

-
- gdb: register signal handler after setting up event token
- This commit fixes the smallest of small possible bug related to signal
- handling. If we look in async_init_signals we see code like this:
-
- signal (SIGQUIT, handle_sigquit);
- sigquit_token =
- create_async_signal_handler (async_do_nothing, NULL, "sigquit");
-
- Then if we look in handle_sigquit we see code like this:
-
- mark_async_signal_handler (sigquit_token);
- signal (sig, handle_sigquit);
-
- Finally, in mark_async_signal_handler we have:
-
- async_handler_ptr->ready = 1;
-
- Where async_handler_ptr will be sigquit_token.
-
- What this means is that if a SIGQUIT arrive in async_init_signals
- after handle_sigquit has been registered, but before sigquit_token has
- been initialised, then GDB will most likely crash.
-
- The chance of this happening is tiny, but fixing this is trivial, just
- ensure we call create_async_signal_handler before calling signal, so
- lets do that.
-
- There are no tests for this. Trying to land a signal in the right
- spot is pretty hit and miss. I did try changing the current HEAD GDB
- like this:
-
- signal (SIGQUIT, handle_sigquit);
- raise (SIGQUIT);
- sigquit_token =
- create_async_signal_handler (async_do_nothing, NULL, "sigquit");
-
- And confirmed that this did result in a crash, after my change I tried
- this:
-
- sigquit_token =
- create_async_signal_handler (async_do_nothing, NULL, "sigquit");
- signal (SIGQUIT, handle_sigquit);
- raise (SIGQUIT);
-
- And GDB now starts up just fine.

-
- gdb: terminate upon receipt of SIGFPE
- GDB's SIGFPE handling is broken, this is PR gdb/16505 and
- PR gdb/17891.
-
- We currently try to use an async event token to process SIGFPE. So,
- when a SIGFPE arrives the signal handler calls
- mark_async_signal_handler then returns, effectively ignoring the
- signal (for now).
-
- The intention is that later the event loop will see that the async
- token associated with SIGFPE has been marked and will call the async
- handler, which just throws an error.
-
- The problem is that SIGFPE is not safe to ignore. Ignoring a
- SIGFPE (unless it is generated artificially, e.g. by raise()) is
- undefined behaviour, after ignoring the signal on many targets we
- return to the instruction that caused the SIGFPE to be raised, which
- immediately causes another SIGFPE to be raised, we get stuck in an
- infinite loop. The behaviour is certainly true on x86-64.
-
- To view this behaviour I simply added some dummy code to GDB that
- performed an integer divide by zero, compiled this on x86-64
- GNU/Linux, ran GDB and saw GDB hang.
-
- In this commit, I propose to remove all special handling of SIGFPE and
- instead just let GDB make use of the default SIGFPE action, that is,
- to terminate the process.
-
- The only user visible change here should be:
-
- - If a user sends a SIGFPE to GDB using something like kill,
- previously GDB would just print an error and remain alive, now GDB
- will terminate. This is inline with what happens if the user
- sends GDB a SIGSEGV from kill though, so I don't see this as an
- issue.
-
- - If a bug in GDB causes a real SIGFPE, previously the users GDB
- session would hang. Now the GDB session will terminate. Again,
- this is inline with what happens if GDB receives a SIGSEGV due to
- an internal bug.
-
- In bug gdb/16505 there is mention that it would be nice if GDB did
- more than just terminate when receiving a fatal signal. I haven't
- done that in this commit, but later commits will move in that
- direction.

- AMX-BF16 insns. While not part of the IEEE standard, the format is
- sufficiently standardized to warrant handling in config/atof-ieee.c.
- Arm, where custom handling was implemented, may want to leverage this as
- well. To be able to also use the hex forms supported for other floating
- point formats, a small addition to the generic hex_float() is needed.
-
- Extend existing x86 testcases.

- x86/ELF: fix .tfloat output with hex input
- The ELF psABI-s are quite clear here: On 32-bit the data type is 12
- bytes long (with 2 bytes of trailing padding), while on 64-bit it is 16
- bytes long (with 6 bytes of padding). Make hex_float() capable of
- handling such padding.
-
- Note that this brings the emitted data size of .dc.x / .dcb.x in line
- also for non-ELF targets; so far they were different depending on input
- format (dec vs hex).

- x86/ELF: fix .ds.x output
- The ELF psABI-s are quite clear here: On 32-bit the underlying data type
- is 12 bytes long (with 2 bytes of trailing padding), while on 64-bit it
- is 16 bytes long (with 6 bytes of padding). Make s_space() capable of
- handling 'x' (and 'p') type floating point being other than 12 bytes
- wide (also adjusting documentation). This requires duplicating the
- definition of X_PRECISION in the target speciifc header; the compiler
- would complain if this was out of sync with config/atof-ieee.c.
-
- Note that for now padding space doesn't get separated from actual
- storage, which means that things will work correctly only for little-
- endian cases, and which also means that by specifying large enough
- numbers padding space can be set to non-zero. Since the logic is needed
- for a single little-endian architecture only for now, I'm hoping that
- this might be acceptable for the time being; otherwise the change will
- become more intrusive.
-
- Note also that this brings the emitted data size of .ds.x vs .tfloat in
- line for non-ELF targets as well; the issue will be even more obvious
- when further taking into account a subsequent patch fixing .dc.x/.dcb.x
- (where output sizes currently differ depending on input format).

- PR28163, Segment fault in function rl78_special_reloc
- Relocation offset checks were completely missing in the rl78 backend,
- allowing a relocation to write over memory anywhere. This was true
- for rl78_special_reloc, a function primarily used when applying debug
- relocations, and in rl78_elf_relocate_section used by the linker.
-
- This patch fixes those problems by correcting inaccuracies in the
- relocation howtos, then uses those howtos to sanity check relocation
- offsets before applying relocations. In addition, the patch
- implements overflow checking using the howto information rather than
- the ad-hoc scheme implemented in relocate_section. I implemented the
- overflow checking in rl78_special_reloc too.

- Ignore .debug_types when reading .debug_aranges
- I noticed that the fission-reread.exp test case can cause a complaint
- when run with --target_board=cc-with-debug-names:
-
- warning: Section .debug_aranges in [...]/fission-reread has duplicate debug_info_offset 0x0, ignoring .debug_aranges.
-
- The bug here is that this executable has both .debug_info and
- .debug_types, and both have a CU at offset 0x0. This triggers the
- duplicate warning.
-
- Because .debug_types doesn't provide any address ranges, these CUs can
- be ignored. That is, this bug turns out to be another regression from
- the info/types merger patch.
-
- This patch fixes the problem by having this loop igore type units.

- gdb: iterate only on vfork parent threads in handle_vfork_child_exec_or_exit
- I spotted what I think is a buglet in proceed_after_vfork_done. After a
- vfork child exits or execs, we resume all the threads of the parent. To
- do so, we iterate on all threads using iterate_over_threads with the
- proceed_after_vfork_done callback. Each thread is resumed if the
- following condition is true:
-
- if (thread->ptid.pid () == pid
- && thread->state == THREAD_RUNNING
- && !thread->executing
- && !thread->stop_requested
- && thread->stop_signal () == GDB_SIGNAL_0)
-
- where `pid` is the pid of the vfork parent. This is not multi-target
- aware: since it only filters on pid, if there is an inferior with the
- same pid in another target, we could end up resuming a thread of that
- other inferior. The chances of the stars aligning for this to happen
- are tiny, but still.
-
- Fix that by iterating only on the vfork parent's threads, instead of on
- all threads. This is more efficient, as we iterate on just the required
- threads (inferiors have their own thread list), and we can drop the pid
- check. The resulting code is also more straightforward in my opinion,
- so it's a win-win.

- guile: fix smob exports
- Before Guile v2.1 [1], calls to `scm_make_smob_type' implicitly added
- the created class to the exports list of (oop goops); v2.1+ does not
- implicitly create bindings in any modules. This means that the GDB
- manual subsection documenting exported types is not quite right when GDB
- is linked against Guile <v2.1 (types are exported from (oop goops))
- instead of (gdb)) and incorrect when linked against Guile v2.1+ (types
- are not bound to any variables at all!).
-
- There is a range of cases in which it's necessary or convenient to be
- able to refer to a GDB smob type, for instance:
-
- - Pattern matching based on the type of a value.
- - Defining GOOPS methods handling values from GDB (GOOPS methods
- typically use dynamic dispatch based on the types of the arguments).
- - Type-checking assertions when applying some defensive programming on
- an interface.
- - Generally any other situation one might encounter in a dynamically
- typed language that might need some introspection.
-
- If you're more familiar with Python, it would be quite similar to being
- unable to refer to the classes exported from the GDB module (which is to
- say: not crippling for the most part, but makes certain tasks more
- difficult than necessary).
-
- This commit makes a small change to GDB's smob registration machinery
- to make sure registered smobs get exported from the current
- module. This will likely cause warnings to the user about conflicting
- exports if they load both (gdb) and (oop goops) from a GDB linked
- against Guile v2.0, but it shouldn't impact functionality (and seemed
- preferable to trying to un-export bindings from (oop goops) if v2.0
- was detected).

- ) from repro/usr/lib/libstdc++.so.6

-
- The warning is about the following:
- - in find_pc_sect_compunit_symtab we try to find the address
- (0x7ff8feb2c218 / 0x7ff8feb2c21d) in the symtabs.
- - that fails, so we try again in the partial symtabs.
- - we find a matching partial symtab
- - however, the partial symtab has a full symtab, so
- we should have found a matching symtab in the first step.
-
- The addresses are:
- ...
- (gdb) info sym 0x7ff8feb2c218

- section .text of repro/usr/lib/libstdc++.so.6

- ...
- $ nm -C repro/usr/lib/libstdc++.so.6.0.29 | grep 000000000009c218
- 000000000009c218 t __gnu_debug::_Error_formatter::_M_error() const \

- ...
- which belong to function __gnu_debug::_Error_formatter::_M_error() in
- /build/gcc/src/gcc/libstdc++-v3/src/c++11/debug.cc.
-
- The partial symtab that is found for the addresses is instead the one for
- /build/gcc/src/gcc/libstdc++-v3/src/c++98/bitmap_allocator.cc, which is
- incorrect.
-
- This happens as follows.
-
- The bitmap_allocator.cc CU has DW_AT_ranges at .debug_rnglist offset 0x4b50:
- ...
- 00004b50 0000000000000000 0000000000000056
- 00004b5a 00000000000a4790 00000000000a479c
- 00004b64 00000000000a47a0 00000000000a47ac
- ...
-
- When reading the first range 0x0..0x56, it doesn't trigger the "start address
- of zero" complaint here:
- ...
- /* A not-uncommon case of bad debug info.
- Don't pollute the addrmap with bad data. */
- if (range_beginning + baseaddr == 0
- && !per_objfile->per_bfd->has_section_at_zero)
- {
- complaint (_(".debug_rnglists entry has start address of zero"
- " [in module %s]"), objfile_name (objfile));
- continue;
- }
- ...
- because baseaddr != 0, which seems incorrect given that when loading the
- shared library individually in gdb (and consequently baseaddr == 0), we do see
- the complaint.
-
- Consequently, we run into this case in dwarf2_get_pc_bounds:
- ...
- if (low == 0 && !per_objfile->per_bfd->has_section_at_zero)
- return PC_BOUNDS_INVALID;
- ...
- which then results in this code in process_psymtab_comp_unit_reader being
- called with cu_bounds_kind == PC_BOUNDS_INVALID, which sets the set_addrmap
- argument to 1:
- ...
- scan_partial_symbols (first_die, &lowpc, &highpc,
- cu_bounds_kind <= PC_BOUNDS_INVALID, cu);
- ...
- and consequently, the CU addrmap gets build using address info from the
- functions.
-
- During that process, addrmap_set_empty is called with a range that includes
- 0x9c218 and 0x9c21d:
- ...
- (gdb) p /x start
- $7 = 0x9989c
- (gdb) p /x end_inclusive
- $8 = 0xb200d
- ...
- but it's called for a function at DIE 0x54153 with DW_AT_ranges at 0x40ae:
- ...
- 000040ae 00000000000b1ee0 00000000000b200e
- 000040b9 000000000009989c 00000000000998c4
- 000040c3 <End of list>
- ...
- and neither range includes 0x9c218 and 0x9c21d.
-
- This is caused by this code in partial_die_info::read:
- ...
- if (dwarf2_ranges_read (ranges_offset, &lowpc, &highpc, cu,
- nullptr, tag))
- has_pc_info = 1;
- ...
- which pretends that the function is located at addresses 0x9989c..0xb200d,
- which is indeed not the case.
-
- This patch fixes the first problem encountered: fix the "start address of
- zero" complaint warning by removing the baseaddr part from the condition.
- Same for dwarf2_ranges_process.
-
- The effect is that:
- - the complaint is triggered, and
- - the warning / Internal error is no longer triggered.
-
- This does not fix the observed problem in partial_die_info::read, which is
- filed as PR28200.

- Tested on x86_64-linux.

- When we encounter a .TOC. symbol in the object we are loading,
- we need to associate this with the .toc section in order to
- properly resolve other symbols in the object. IF a .toc section
- is not found, iterate the sections until we find one with the
- SEC_ALLOC flag. If that also fails, fall back to using
- the *ABS* section, pointed to by bfd_abs_section_ptr.

- gdb/testsuite: gdb.base/attach.exp: expose bug when testing with native-extended-gdbserver
- In gdb.base/attach.exp, proc do_attach_failure_tests, we attach to a
- process. When then try to attach to the same process in another
- inferior, expecting it to fail. We then come back to the first inferior
- and try to kill it, to clean up the test. When using the
- native-extended-gdbserver board, this "kill" test passes, even though it
- didn't actually work:
-
- add-inferior

- When the second attach fails, gdbserver seems to break the connection

-
- Make the expected output regexp for the kill command tighter (it
- currently accepts anything). Use "set confirm off" so we don't have to
- deal with the confirmation. And to be really sure the extended-remote
- target still works, try to run the inferior again after killing. The
- now tests are kfail'ed when the target is gdbserver.

- gdb/testsuite: gdb.base/attach.exp: fix support check in test_command_line_attach_run
- When running this test with the native-extended-gdbserver, we get:
-
- main () at /home/simark/src/binutils-gdb/gdb/testsuite/gdb.base/attach.c:19
- 19 while (! should_exit)
- The program being debugged has been started already.
- Start it from the beginning? (y or n) PASS: gdb.base/attach.exp: cmdline attach run: run to prompt
- y
- Don't know how to run. Try "help target".
- (gdb) FAIL: gdb.base/attach.exp: cmdline attach run: run to main
-
- This test tests using both "-p <pid>" and "-ex start" on the command line,
- making sure that we first attach and then run.
-
- Normally, after that "y", we should see the program running again.
- However, a particuliarity of the native-extended-gdbserver is that it
- uses "set auto-connect-native-target off" on the command line. The full
- GDB command line is:
-
- ./gdb -nw -nx -data-directory /home/simark/build/binutils-gdb/gdb/testsuite/../data-directory \
- -iex set height 0 -iex set width 0 -ex set auto-connect-native-target off \
- -ex set sysroot -quiet -iex set height 0 -iex set width 0 --pid=536609 -ex start
-
- The attach succeeds. I guess it is done before "set
- auto-connect-native-target off", or it somehow bypasses it. When the
- "start" is executed, the native target is unpushed, while killing the
- existing process, but not re-pushed, due to "set
- auto-connect-native-target off". So we get that "Don't know how to run"
- message.
-
- Really, I think it's a case of the test doing things incompatible with
- the board, I think it should just be skipped. And as we can see with
- the current code, there were some attempts at doing this, just using the
- wrong checks:
-
- - isnative: this is a dejagnu proc which checks if the target board has
- the same triplet as the build machine. In the case of
- native-extended-gdbserver, it does.
- - is_remote target: this checks whether the target board is remote, as
- in executing on a different machin. native-extended-gdbserver is not
- remote.
-
- Since the --pid option specifically attaches to a process using the
- native target, change the test to use gdb_is_target_native instead.
-
- gdb/testsuite/ChangeLog:
-
- * gdb.base/attach.exp (test_command_line_attach_run): Use
- gdb_is_target_native to check if test is supported.

- Simplify dwarf_expr_context class interface
- Idea of this patch is to get a clean and simple public interface for
- the dwarf_expr_context class, looking like:
-
- - constructor,
- - destructor,
- - push_address method and
- - evaluate method.
-
- Where constructor should only ever require a target architecture
- information. This information is held in per object file
- (dwarf2_per_objfile) structure, so it makes sense to keep that
- structure as a constructor argument. It also makes sense to get the
- address size from that structure, but unfortunately that interface
- doesn't exist at the moment, so the dwarf_expr_context class user
- needs to provide that information.
-
- The push_address method is used to push a CORE_ADDR as a value on
- top of the DWARF stack before the evaluation. This method can be
- later changed to push any struct value object on the stack.
-
- The evaluate method is the method that evaluates a DWARF expression
- and provides the evaluation result, in a form of a single struct
- value object that describes a location. To do this, the method requires
- a context of the evaluation, as well as expected result type
- information. If the type information is not provided, the DWARF generic
- type will be used instead.
-
- To avoid storing the gdbarch information in the evaluator object, that
- information is now always acquired from the per_objfile object.
-
- All data members are now private and only visible to the evaluator
- class, so a m_ prefix was added to all of their names to reflect that.
- To make this distinction clear, they are also accessed through objects
- this pointer, wherever that was not the case before.

-
- Move piece_closure and its support to expr.c
- Following 5 patches series is trying to clean up the interface of the
- DWARF expression evaluator class (dwarf_expr_context).
-
- After merging all expression evaluators into one class, the next
- logical step is to make a clean user interface for that class. To do
- that, we first need to address the issue of class users writing and
- reading the internal data of the class directly.
-
- Fixing the case of writing is simple, it makes sense for an evaluator
- instance to be per architecture basis. Currently, the best separation
- seems to be per object file, so having that data (dwarf2_per_objfile)
- as a constructor argument makes sense. It also makes sense to get the
- address size from that object file, but unfortunately that interface
- does not exist at the moment.
-
- Luckily, address size information is already available to the users
- through other means. As a result, the address size also needs to be a
- class constructor argument, at least until a better interface for
- acquiring that information from an object file is implemented.
-
- The rest of the user written data comes down to a context of an
- evaluated expression (compilation unit context, frame context and
- passed in buffer context) and a source type information that a result
- of evaluating expression is representing. So, it makes sense for all of
- these to be arguments of an evaluation method.
-
- To address the problem of reading the dwarf_expr_context class
- internal data, we first need to understand why it is implemented that
- way?
-
- This is actualy a question of which existing class can be used to
- represent both values and a location descriptions and why it is not
- used currently?
-
- The answer is in a struct value class/structure, but the problem is
- that before the evaluators were merged, only one evaluator had an
- infrastructure to resolve composite and implicit pointer location
- descriptions.
-
- After the merge, we are now able to use the struct value to represent
- any result of the expression evaluation. It also makes sense to move
- all infrastructure for those location descriptions to the expr.c file
- considering that that is the only place using that infrastructure.
-
- What we are left with in the end is a clean public interface of the
- dwarf_expr_context class containing:
-
- - constructor,
- - destructor,
- - push_address method and
- - eval_exp method.
-
- The idea with this particular patch is to move piece_closure structure
- and the interface that handles it (lval_funcs) to expr.c file.
-
- While implicit pointer location descriptions are still not useful in
- the CFI context (of the AMD's DWARF standard extensions), the composite
- location descriptions are certainly necessary to describe a results of
- specific compiler optimizations.
-
- Considering that a piece_closure structure is used to represent both,
- there was no benefit in splitting them.

- Merge evaluate_for_locexpr_baton evaluator
- The evaluate_for_locexpr_baton is the last derived class from the
- dwarf_expr_context class. It's purpose is to support the passed in
- buffer functionality.
-
- Although, it is not really necessary to merge this class with it's
- base class, doing that simplifies new expression evaluator design.
-
- Considering that this functionality is going around the DWARF standard,
- it is also reasonable to expect that with a new evaluator design and
- extending the push object address functionality to accept any location
- description, there will be no need to support passed in buffers.
-
- Alternatively, it would also makes sense to abstract the interaction

-
- Move frame context info to dwarf_expr_context
- Following 15 patches in this patch series is cleaning up the design of
- the DWARF expression evaluator (dwarf_expr_context) to make future
- extensions of that evaluator easier and cleaner to implement.
-
- There are three subclasses of the dwarf_expr_context class
- (dwarf_expr_executor, dwarf_evaluate_loc_desc and
- evaluate_for_locexpr_baton). Here is a short description of each class:
-
- - dwarf_expr_executor is evaluating a DWARF expression in a context
- of a Call Frame Information. The overridden methods of this subclass
- report an error if a specific DWARF operation, represented by that
- method, is not allowed in a CFI context. The source code of this
- subclass lacks the support for composite as well as implicit pointer
- location description.
-
- - dwarf_evaluate_loc_desc can evaluate any expression with no
- restrictions. All of the methods that this subclass overrides are
- actually doing what they are intended to do. This subclass contains
- a full support for all location description types.
-
- - evaluate_for_locexpr_baton subclass is a specialization of the
- dwarf_evaluate_loc_desc subclass and it's function is to add
- support for passed in buffers. This seems to be a way to go around
- the fact that DWARF standard lacks a bit offset support for memory
- location descriptions as well as using any location description for
- the push object address functionality.
-
- It all comes down to this question: what is a function of a DWARF
- expression evaluator?
-
- Is it to evaluate the expression in a given context or to check the
- correctness of that expression in that context?
-
- Currently, the only reason why there is a dwarf_expr_executor subclass
- is to report an invalid DWARF expression in a context of a CFI, but is
- that what the evaluator is supposed to do considering that the evaluator
- is not tied to a given DWARF version?
-
- There are more and more vendor and GNU extensions that are not part of
- the DWARF standard, so is it that impossible to expect that some of the
- extensions could actually lift the previously imposed restrictions of
- the CFI context? Not to mention that every new DWARF version is lifting
- some restrictions anyway.
-
- The thing that makes more sense for an evaluator to do, is to take the
- context of an evaluation and checks the requirements of every operation
- evaluated against that context. With this approach, the evaluator would
- report an error only if parts of the context, necessary for the
- evaluation, are missing.
-
- If this approach is taken, then the unification of the
- dwarf_evaluate_loc_desc, dwarf_expr_executor and dwarf_expr_context
- is the next logical step. This makes a design of the DWARF expression
- evaluator cleaner and allows more flexibility when supporting future
- vendor and GNU extensions.
-
- Additional benefit here is that now all evaluators have access to all
- location description types, which means that a vendor extended CFI
- rules could support composite location description as well. This also
- means that a new evaluator interface can be changed to return a single
- struct value (that describes the result of the evaluation) instead of
- a caller poking around the dwarf_expr_context internal data for answers
- (like it is done currently).
-
- This patch starts the merging process by moving the frame context
- information and support from dwarf_expr_executor and
- dwarf_evaluate_loc_desc to dwarf_expr_context evaluator. The idea
- is to report an error when a given operation requires a frame
- information to be resolved, if that information is not present.

-
- Replace the symbol needs evaluator with a parser
- This patch addresses a design problem with the symbol_needs_eval_context
- class. It exposes the problem by introducing two new testsuite test
- cases.
-
- To explain the issue, I first need to explain the dwarf_expr_context
- class that the symbol_needs_eval_context class derives from.
-
- The intention behind the dwarf_expr_context class is to commonize the
- DWARF expression evaluation mechanism for different evaluation
- contexts. Currently in gdb, the evaluation context can contain some or
- all of the following information: architecture, object file, frame and
- compilation unit.
-
- Depending on the information needed to evaluate a given expression,
- there are currently three distinct DWARF expression evaluators:
-
- - Frame: designed to evaluate an expression in the context of a call
- frame information (dwarf_expr_executor class). This evaluator doesn't
- need a compilation unit information.
-
- - Location description: designed to evaluate an expression in the
- context of a source level information (dwarf_evaluate_loc_desc
- class). This evaluator expects all information needed for the
- evaluation of the given expression to be present.
-
- - Symbol needs: designed to answer a question about the parts of the
- context information required to evaluate a DWARF expression behind a
- given symbol (symbol_needs_eval_context class). This evaluator
- doesn't need a frame information.
-
- The functional difference between the symbol needs evaluator and the
- others is that this evaluator is not meant to interact with the actual
- target. Instead, it is supposed to check which parts of the context
- information are needed for the given DWARF expression to be evaluated by
- the location description evaluator.
-
- The idea is to take advantage of the existing dwarf_expr_context
- evaluation mechanism and to fake all required interactions with the
- actual target, by returning back dummy values. The evaluation result is
- returned as one of three possible values, based on operations found in a
- given expression:
-
- - SYMBOL_NEEDS_NONE,
- - SYMBOL_NEEDS_REGISTERS and
- - SYMBOL_NEEDS_FRAME.
-
- The problem here is that faking results of target interactions can yield
- an incorrect evaluation result.
-
- For example, if we have a conditional DWARF expression, where the
- condition depends on a value read from an actual target, and the true
- branch of the condition requires a frame information to be evaluated,
- while the false branch doesn't, fake target reads could conclude that a
- frame information is not needed, where in fact it is. This wrong
- information would then cause the expression to be actually evaluated (by
- the location description evaluator) with a missing frame information.
- This would then crash the debugger.
-
- The gdb.dwarf2/symbol_needs_eval_fail.exp test introduces this
- scenario, with the following DWARF expression:
-
- DW_OP_addr $some_variable
- DW_OP_deref
-
- # conditional jump to DW_OP_bregx
- DW_OP_bra 4
- DW_OP_lit0
-
- # jump to DW_OP_stack_value
- DW_OP_skip 3
- DW_OP_bregx $dwarf_regnum 0
- DW_OP_stack_value
-
- This expression describes a case where some variable dictates the
- location of another variable. Depending on a value of some_variable, the
- variable whose location is described by this expression is either read
- from a register or it is defined as a constant value 0. In both cases,
- the value will be returned as an implicit location description on the
- DWARF stack.
-
- Currently, when the symbol needs evaluator fakes a memory read from the
- address behind the some_variable variable, the constant value 0 is used
- as the value of the variable A, and the check returns the
- SYMBOL_NEEDS_NONE result.
-
- This is clearly a wrong result and it causes the debugger to crash.
-
- The scenario might sound strange to some people, but it comes from a
- SIMD/SIMT architecture where $some_variable is an execution mask. In
- any case, it is a valid DWARF expression, and GDB shouldn't crash while
- evaluating it. Also, a similar example could be made based on a
- condition of the frame base value, where if that value is concluded to
- be 0, the variable location could be defaulted to a TLS based memory
- address.
-
- The gdb.dwarf2/symbol_needs_eval_timeout.exp test introduces a second
- scenario. This scenario is a bit more abstract due to the DWARF
- assembler lacking the CFI support, but it exposes a different
- manifestation of the same problem. Like in the previous scenario, the
- DWARF expression used in the test is valid:
-
- DW_OP_lit1
- DW_OP_addr $some_variable
- DW_OP_deref
-
- # jump to DW_OP_fbreg
- DW_OP_skip 4
- DW_OP_drop
- DW_OP_fbreg 0
- DW_OP_dup
- DW_OP_lit0
- DW_OP_eq
-
- # conditional jump to DW_OP_drop
- DW_OP_bra -9
- DW_OP_stack_value
-
- Similarly to the previous scenario, the location of a variable A is an
- implicit location description with a constant value that depends on a
- value held by a global variable. The difference from the previous case
- is that DWARF expression contains a loop instead of just one branch. The
- end condition of that loop depends on the expectation that a frame base
- value is never zero. Currently, the act of faking the target reads will
- cause the symbol needs evaluator to get stuck in an infinite loop.
-
- Somebody could argue that we could change the fake reads to return
- something else, but that would only hide the real problem.
-
- The general impression seems to be that the desired design is to have
- one class that deals with parsing of the DWARF expression, while there
- are virtual methods that deal with specifics of some operations.
-
- Using an evaluator mechanism here doesn't seem to be correct, because
- the act of evaluation relies on accessing the data from the actual
- target with the possibility of skipping the evaluation of some parts of
- the expression.
-
- To better explain the proposed solution for the issue, I first need to
- explain a couple more details behind the current design:
-
- There are multiple places in gdb that handle DWARF expression parsing
- for different purposes. Some are in charge of converting the expression
- to some other internal representation (decode_location_expression,
- disassemble_dwarf_expression and dwarf2_compile_expr_to_ax), some are
- analysing the expression for specific information
- (compute_stack_depth_worker) and some are in charge of evaluating the
- expression in a given context (dwarf_expr_context::execute_stack_op
- and decode_locdesc).
-
- The problem is that all those functions have a similar (large) switch
- statement that handles each DWARF expression operation. The result of
- this is a code duplication and harder maintenance.
-
- As a step into the right direction to solve this problem (at least for
- the purpose of a DWARF expression evaluation) the expression parsing was
- commonized inside of an evaluator base class (dwarf_expr_context). This
- makes sense for all derived classes, except for the symbol needs
- evaluator (symbol_needs_eval_context) class.
-
- As described previously the problem with this evaluator is that if the
- evaluator is not allowed to access the actual target, it is not really
- evaluating.
-
- Instead, the desired function of a symbol needs evaluator seems to fall
- more into expression analysis category. This means that a more natural
- fit for this evaluator is to be a symbol needs analysis, similar to the
- existing compute_stack_depth_worker analysis.
-
- Another problem is that using a heavyweight mechanism of an evaluator
- to do an expression analysis seems to be an unneeded overhead. It also
- requires a more complicated design of the parent class to support fake
- target reads.
-
- The reality is that the whole symbol_needs_eval_context class can be
- replaced with a lightweight recursive analysis function, that will give
- more correct result without compromising the design of the
- dwarf_expr_context class. The analysis treats the expression byte
- stream as a DWARF operation graph, where each graph node can be
- visited only once and each operation can decide if the frame context
- is needed for their evaluation.
-
- The downside of this approach is adding of one more similar switch
- statement, but at least this way the new symbol needs analysis will be
- a lightweight mechnism and it will provide a correct result for any
- given DWARF expression.
-
- A more desired long term design would be to have one class that deals
- with parsing of the DWARF expression, while there would be a virtual
- methods that deal with specifics of some DWARF operations. Then that
- class would be used as a base for all DWARF expression parsing mentioned
- at the beginning.
-
- This however, requires a far bigger changes that are out of the scope
- of this patch series.
-
- The new analysis requires the DWARF location description for the
- argc argument of the main function to change in the assembly file
- gdb.python/amd64-py-framefilter-invalidarg.S. Originally, expression
- ended with a 0 value byte, which was never reached by the symbol needs
- evaluator, because it was detecting a stack underflow when evaluating
- the operation before. The new approach does not simulate a DWARF
- stack anymore, so the 0 value byte needs to be removed because it
- makes the DWARF expression invalid.

- gdb/testsuite: update test gdb.base/step-over-syscall.exp
- I was looking at PR gdb/19675 and the related test
- gdb.base/step-over-syscall.exp. This test includes a call to kfail
- when we are testing a displaced step over a clone syscall.
-
- While looking at the test I removed the call to kfail and ran the
- test, and was surprised that the test passed.
-
- I ran the test a few times and it does sometimes fail, but mostly it
- passed fine.
-
- PR gdb/19675 describes how, when we displaced step over a clone, the
- new thread is created with a $pc in the displaced step buffer. GDB
- then fails to "fix" this $pc (for the new thread), and the thread will
- be set running with its current $pc value. This means that the new
- thread will just start executing from whatever happens to be after the
- displaced stepping buffer.
-
- In the original PR gdb/19675 bug report Yao Qi was seeing the new
- thread cause a segfault, the problem is, what actually happens is
- totally undefined.
-
- On my machine, I'm seeing the new thread reenter main, it then starts
- trying to run the test again (in the new thread). This just happens
- to be safe enough (in this simple test) that most of the time the
- inferior doesn't crash.
-
- In this commit I try to make the test slightly more likely to fail by
- doing a couple of things.
-
- First, I added a static variable to main, this is set true when the
- first thread enters main, if a second thread ever enters main then I
- force an abort.
-
- Second, when the test is finishing I want to ensure that the new
- threads have had a chance to do "something bad" if they are going to.
- So I added a global counter, as each thread starts successfully it
- decrements the counter. The main thread does not proceed to the final
- marker function (where GDB has placed a breakpoint) until all threads
- have started successfully. This means that if the newly created
- thread doesn't successfully enter clone_fn then the counter will never
- reach zero and the test will timeout.
-
- With these two changes my hope is that the test should fail more
- reliably, and so, I have also changed the test to call setup_kfail
- before the specific steps that we expect to misbehave instead of just
- calling kfail and skipping parts of the test completely. The benefit
- of this is that if/when we fix GDB this test will start to KPASS and
- we'll know to update this test to remove the setup_kfail call.

- gdb: Use unwinder name in frame_info::to_string
- While working on a stack unwinding issue using 'set debug frame on', I
- noticed the frame_info::to_string method could be slightly improved.
-
- Unwinders have been given a name in
- a154d838a70e96d888620c072e2d6ea8bdf044ca. Before this patch, frame_info
- debug output prints the host address of the used unwinder, which is not
- easy to interpret. This patch proposes to use the unwinder name
- instead since we now have it.
-
- Before the patch:
-
- {level=1,type=NORMAL_FRAME,unwind=0x2ac1763ec0,pc=0x3ff7fc3460,id={stack=0x3ff7ea79b0,code=0x0000003ff7fc33ac,!special},func=0x3ff7fc33ac}
-

- gdb/testsuite: fix gdb.base/info-macros.exp with clang
- The test gdb.base/info-macros.exp says that it doesn't pass the "debug"
- option to prepare_for_testing because that would cause -g to appear
- after -g3 on the command line, and that would cause some gcc versions to
- not include macro info. I don't know what gcc versions this refers to.
- I tested with gcc 4.8, and that works fine with -g after -g3.
-
- The current state is problematic when testing with CC_FOR_TARGET=clang,
- because then only -fdebug-macro is included. No -g switch if included,
- meaning we get a binary without any debug info, and the test fails.
-
- One way to fix it would be to add "debug" to the options when the
- compiler is clang.
-
- However, the solution I chose was to specify "debug" in any case, even
- for gcc. Other macro tests such as gdb.base/macscp.exp do perfectly
- fine with it. Also, this lets the test use the debug flag specified by
- the board file. For example, we can test with GCC and DWARF 5, with:
-
- $ make check RUNTESTFLAGS="--target_board unix/gdb:debug_flags=-gdwarf-5" TESTS="gdb.base/info-macros.exp"
-
- With the hard-coded -g3, this wouldn't actually test with DWARF 5.

- gdb: avoid dereferencing empty str_offsets_base optional in dwarf_decode_macros
- Since 4d7188abfdf2 ("gdbsupport: add debug assertions in
- gdb::optional::get"), some macro-related tests fail on Ubuntu 20.04 with
- the system gcc 9.3.0 compiler when building with _GLIBCXX_DEBUG. For
- example, gdb.base/info-macros.exp results in:
-
- (gdb) break -qualified main
- /home/smarchi/src/binutils-gdb/gdb/../gdbsupport/gdb_optional.h:206: internal-error: T& gdb::optional<T>::get() [with T = long unsigned int]: Assertion `this->has_value ()' failed.
-
- The binary contains DWARF 4 debug info and includes a pre-standard
- (pre-DWARF 5) .debug_macro section. The CU doesn't have a
- DW_AT_str_offsets_base attribute (which doesn't exist in DWARF 4). The
- field dwarf2_cu::str_offsets_base is therefore empty. At
- dwarf2/read.c:24138, we unconditionally read the value in the optional,
- which triggers the assertion shown above.
-
- The same thing happens when building the test program with DWARF 5 with
- the same gcc compiler, as that version of gcc doesn't use indirect
- string forms, even with DWARF 5. So it still doesn't add a
- DW_AT_str_offsets_base attribute on the CU.
-
- Fix that by propagating down a gdb::optional<ULONGEST> for the str
- offsets base instead of ULONGEST. That value is only used in
- dwarf_decode_macro_bytes, when encountering an "strx" macro operation
- (DW_MACRO_define_strx or DW_MACRO_undef_strx). Add a check there that
- we indeed have a value in the optional before reading it. This is
- unlikely to happen, but could happen in theory with an erroneous file
- that uses DW_MACRO_define_strx but does not provide a
- DW_AT_str_offsets_base (in practice, some things would probably have
- failed before and stopped processing of debug info). I tested the
- complaint by inverting the condition and using a clang-compiled binary,
- which uses the strx operators. This is the result:
-
- During symbol reading: use of DW_MACRO_define_strx with unknown string offsets base [in module /home/simark/build/binutils-gdb/gdb/testsuite/outputs/gdb.base/info-macros/info-macros]
-
- The test now passes cleanly with the setup mentioned above, and the
- testsuite looks on par with how it was before 4d7188abfdf2.

- PR28162, segment fault in mips_elf_assign_gp
- For the testcase in the PR, _bfd_mips_elf32_gprel16_reloc is passed a
- NULL output_bfd. As expected for reloc special functions if called by
- objdump or when final linking. The function attempts to find the
- output by
- output_bfd = symbol->section->output_section->owner;
- That makes some sense, since when handling a gp-relative reloc we need
- the relevant gp to which the symbol is relative. Possibly the gp
- value can be one for a shared library? But that doesn't seem useful
- or supported by the various abi docs and won't work as written.
- Symbols defined in shared libraries have section->output_section
- NULL, and what's more the code in mips_elf_assign_gp isn't set up to
- look at shared library symbols.
-
- Also, if the symbol is a SHN_ABS one the owner of *ABS* section is
- NULL, which will result in the testcase segfault. The only gp to
- which an absolute symbol can be relative is the linker output bfd when
- linking, or the input bfd when not. This patch arranges to do that
- for all gp-relative reloc symbols.

- gdb: follow-fork: push target and add thread in target_follow_fork
- In the context of ROCm-gdb [1], the ROCm target sits on top of the
- linux-nat target. when a process forks, it needs to carry over some
- data from the forking inferior to the fork child inferior. Ideally, the
- ROCm target would implement the follow_fork target_ops method, but there
- are some small problems. This patch fixes these, which helps the ROCm
- target, but also makes things more consistent and a bit nicer in
- general, I believe.
-
- The main problem is: when follow-fork-mode is "parent",
- target_follow_fork is called with the parent as the current inferior.
- When it's "child", target_follow_fork is called with the child as the
- current inferior. This means that target_follow_fork is sometimes
- called on the parent's target stack and sometimes on the child's target
- stack.
-
- The parent's target stack may contain targets above the process target,
- such as the ROCm target. So if follow-fork-child is "parent", the ROCm
- target would get notified of the fork and do whatever is needed. But
- the child's target stack, at that moment, only contains the exec and
- process target copied over from the parent. The child's target stack is
- set up by follow_fork_inferior, before calling target_follow_fork. In
- that case, the ROCm target wouldn't get notified of the fork.
-
- For consistency, I think it would be good to always call
- target_follow_fork on the parent inferior's target stack. I think it
- makes sense as a way to indicate "this inferior has called fork, do
- whatever is needed". The desired outcome of the fork (whether an
- inferior is created for the child, do we need to detach from the child)
- can be indicated by passed parameter.
-
- I therefore propose these changes:
-
- - make follow_fork_inferior always call target_follow_fork with the
- parent as the current inferior. That lets all targets present on the
- parent's target stack do some fork-related handling and push
- themselves on the fork child's target stack if needed.
-
- For this purpose, pass the child inferior down to target_follow_fork
- and follow_fork implementations. This is nullptr if no inferior is
- created for the child, because we want to detach from it.
-
- - as a result, in follow_fork_inferior, detach from the parent inferior
- (if needed) only after the target_follow_fork call. This is needed
- because we want to call target_follow_fork before the parent's
- target stack is torn down.
-
- - hand over to the targets in the parent's target stack (including the
- process target) the responsibility to push themselves, if needed, to
- the child's target stack. Also hand over the responsibility to the
- process target, at the same time, to create the child's initial
- thread (just like we do for follow_exec).
-
- - pass the child inferior to exec_on_vfork, so we don't need to swap
- the current inferior between parent and child. Nothing in
- exec_on_vfork depends on the current inferior, after this change.
-
- Although this could perhaps be replaced with just having the exec
- target implement follow_fork and push itself in the child's target
- stack, like the process target does... We would just need to make
- sure the process target calls beneath()->follow_fork(...). I'm not
- sure about this one.

- gdbsupport: add debug assertions in gdb::optional::get
- The libstdc++ version of optional contains some runtime checks enabled
- when _GLIBCXX_DEBUG is defined. I think it would be useful if our
- version contained similar checks.
-
- Add checks in the two `get` methods, also conditional on _GLIBCXX_DEBUG.
- I think it's simpler to use that macro rather than introducing a new
- GDB-specific one, as I think that if somebody is interested in enabling
- these runtime checks, they'll also be interested in enabling the
- libstdc++ runtime checks (and vice-versa).
-
- I implemented these checks using gdb_assert. Note that gdb_assert
- throws (after querying the user), and we are in noexcept methods. That
- means that std::terminate / abort will immediately be called. I think
- this is ok, since if those were "real" _GLIBCXX_DEBUG checks, abort
- would be called straight away.

- Handle compiler-generated suffixes in Ada names
- The compiler may add a suffix to a mangled name. A typical example
- would be splitting a function and creating a ".cold" variant.
-
- This patch changes Ada decoding (aka demangling) to handle these
- suffixes. It also changes the encoding process to handle them as
- well.
-
- A symbol like "function.cold" will now be displayed to the user as
- "function[cold]". The "." is not simply preserved because that is
- already used in Ada.

-
- Remove uses of fprintf_symbol_filtered
- I believe that many calls to fprintf_symbol_filtered are incorrect.
- In particular, there are some that pass a symbol's print name, like:
-
- fprintf_symbol_filtered (gdb_stdout, sym->print_name (),
- current_language->la_language, DMGL_ANSI);
-
- fprintf_symbol_filtered uses the "demangle" global to decide whether
- or not to demangle -- but print_name does this as well. This can lead
- to double-demangling. Normally this could be innocuous, except I also
- plan to change Ada demangling in a way that causes this to fail.

- Handle type qualifier for enumeration name
- Pierre-Marie noticed that the Ada expression "TYPE'(NAME)" resolved
- incorrectly when "TYPE" was an enumeration type. Here, "NAME" should
- be unambiguous.
-
- This patch fixes this problem. Note that the patch is not perfect --
- it does not give an error if TYPE is an enumeration type but NAME is
- not an enumerator but does have some other meaning in scope. Fixing
- this proved difficult, and so I've left it out.
-
-2021-08-02 Tom Tromey <tromey@adacore.com>
-
- Remove the type_qualifier global
- The type_qualifier global is no longer needed in the Ada expression
- parser, so this removes it.

-2021-08-02 Tom Tromey <tromey@adacore.com>
-
- Defer Ada character literal resolution
- In Ada, an enumeration type can use a character literal as one of the
- enumerators. The Ada expression parser handles the appropriate
- conversion.
-
- It turns out, though, that this conversion was handled incorrectly.
- For an expression like TYPE'(EXP), the conversion would be done for
- any such literal appearing in EXP -- but only the outermost such
- expression should really be affected.
-
- This patch defers the conversion until the resolution phase, fixing
- the bug.
-
-2021-08-02 Tom Tromey <tromey@adacore.com>
-
- Refactor Ada resolution
- In a subsequent patch, it will be convenient if an Ada expression
- operation can supply its own replacement object. This patch refactors
- Ada expression resolution to make this possible.
-
- Remove add_symbols_from_enclosing_procs
- I noticed that add_symbols_from_enclosing_procs is empty, and can be
- removed. The one caller, ada_add_local_symbols, can also be
- simplified, removing some code that, I think, was an incorrect attempt
- to handle nested functions.

- Avoid crash in varobj deletion
- PR varobj/28131 points out a crash in the varobj deletion code. It
- took a while to reproduce this, but essentially what happens is that a
- top-level varobj deletes its root object, then deletes the "dynamic"
- object. However, deletion of the dynamic object may cause
- ~py_varobj_iter to run, which in turn uses gdbpy_enter_varobj:
-
- gdbpy_enter_varobj::gdbpy_enter_varobj (const struct varobj *var)
- : gdbpy_enter (var->root->exp->gdbarch, var->root->exp->language_defn)
- {
- }
-
- However, because var->root has already been destroyed, this is
- invalid.
-
- I've added a new test case. This doesn't reliably crash, but the
- problem can easily be seen under valgrind (and, I presume, with ASAN,
- though I did not try this).
-
- Tested on x86-64 Fedora 32. I also propose putting this on the GDB 11
- branch, with a suitable ChangeLog entry of course.

- gdb: Make the builtin "boolean" type an unsigned type
- When printing the fields of a register that is of a custom struct type,
- the "unpack_bits_as_long ()" function is used:
-
- do_val_print (...)
- cp_print_value_fields (...)
- value_field_bitfield (...)
- unpack_value_bitfield (...)
- unpack_bits_as_long (...)
-
- This function may sign-extend the extracted field while returning it:
-
- val >>= lsbcount;
-
- if (...)
- {
- valmask = (((ULONGEST) 1) << bitsize) - 1;
- val &= valmask;
- if (!field_type->is_unsigned ())
- if (val & (valmask ^ (valmask >> 1)))
- val |= ~valmask;
- }
-
- return val;
-
- lsbcount: Number of lower bits to get rid of.
- bitsize: The bit length of the field to be extracted.
- val: The register value.
- field_type: The type of field that is being handled.
-
- While the logic here is correct, there is a problem when it is
- handling "field_type"s of "boolean". Those types are NOT marked
- as "unsigned" and therefore they end up being sign extended.
- Although this is not a problem for "false" (0), it definitely
- causes trouble for "true".
-
- This patch constructs the builtin boolean type as such that it is
- marked as an "unsigned" entity.
-
- The issue tackled here was first encountered for arc-elf32 target
- running on an x86_64 machine. The unit-test introduced in this change
- has passed for all the targets (--enable-targets=all) running on the
- same x86_64 host.

- gdb: fix nr_bits gdb_assert in append_flags_type_field
- The assertion
-
- gdb_assert (nr_bits >= 1 && nr_bits <= type_bitsize);
-
- is not correct. Well, it's correct in that we do want the number of
- bits to be in the range [1, type_bitsize]. But we don't check anywhere
- that the end of the specified flag is within the containing type.
-
- The following code should generate a failed assertion, as the flag goes
- past the 32 bits of the underlying type, but it's currently not caught:
-
- static void
- test_print_flag (gdbarch *arch)
- {
- type *flags_type = arch_flags_type (arch, "test_type", 32);
- type *field_type = builtin_type (arch)->builtin_uint32;
- append_flags_type_field (flags_type, 31, 2, field_type, "invalid");
- }
-
- (You can test this by registering it as a selftest using
- selftests::register_test_foreach_arc and running.)
-
- Change the assertion to verify that the end bit is within the range of
- the underlying type. This implicitly verifies that nr_bits is not
- too big as well, so we don't need a separate assertion for that.

-
- obsd-nat: Various fixes for fork following.
- - Don't use #ifdef's on ptrace ops. obsd-nat.h didn't include
- <sys/ptrace.h>, so the virtual methods weren't always overridden
- causing the fork following to not work. In addition, the thread and
- fork code is intertwined in ::wait and and the lack of #ifdef's
- there already assumed both were present. Finally, both of these
- ptrace ops have been present in OpenBSD for at least 10 years.
-
- - Move duplicated code to enable PTRACE_FORK event reporting to a
- single function and invoke it on new child processes reported via
- PTRACE_FORK.
-
- - Don't return early from PTRACE_FORK handling, but instead reset
- wptid to the correct ptid if the child reports its event before the
- parent. This allows the ptid fixup code to add thread IDs if the
- first event for a process is a PTRACE_FORK event. This also
- properly returns ptid's with thread IDs when reporting PTRACE_FORK
- events.

- obsd-nat: Various fixes to obsd_nat_target::wait.

- Replace a check for WIFSTOPPED on the returned status from waitpid
- by checking for TARGET_WAITKIND_STOPPED in the parsed status as is
- done in fbsd_nat_target::wait.
-
- - Don't use inferior_ptid when deciding if a new process is a child vs
- parent of the fork. Instead, use find_inferior_pid and assume that
- if an inferior already exists, the pid in question is the parent;
- otherwise, the pid is the child.
-
- - Don't use inferior_ptid when deciding if the ptid of the process
- needs to be updated with an LWP ID, or if this is a new thread.
- Instead, use the approach from fbsd-nat which is to check if a ptid
- without an LWP exists and if so update the ptid of that thread
- instead of adding a new thread.

- On BSDs, get_status is set in _initialize_x86_bsd_nat, but only if
- HAVE_PT_GETDBREGS is defined. PT_GETDBREGS doesn't exist on OpenBSD, so
- get_status (and the other fields of x86_dr_low) are left as nullptr.
-
- OpenBSD doesn't support getting or setting the x86 debug registers, so
- fix by omitting debug register support entirely on OpenBSD:
-
- - Change x86bsd_nat_target to only inherit from x86_nat_target if
- PT_GETDBREGS is supported.
-
- - Don't include x86-nat.o and nat/x86-dregs.o for OpenBSD/amd64. They
- were already omitted for OpenBSD/i386.

- Fix for gdb.tui/tui-layout-asm.exp
- The width of the window is too narrow to display the entire assembly line.
- The width of the columns in the window changes as the test walks thru the
- terminal window output. The column change results in the first and second
- reads of the same line to differ thus causing the test to fail. Increasing
- the width of the window keeps the column width consistent thru the test.
-
- If the test fails, the added check prints an message to the log file if
- the failure may be due to the window being too narrow.

- gas: improve C_BSTAT and C_STSYM symbols handling on XCOFF
- A C_BSTAT debug symbol specifies the beginning of a static block.
- Its n_value is the index of the csect containing static symbols.
- A C_STSYM debug symbol represents the stabstring of a statically
- allocated symbol. Its n_value is the offset in the csect pointed
- by the containing C_BSTAT.
-
- These two special n_value were not correctly handled both when
- generating object files with gas or when reading them with objdump.

- Clean up some things I noticed:

- - we generate a regformats/microblaze-with-stack-protect.dat file. I
- don't think this is used. It could be used by a GDBserver built for
- Microblaze, but GDBserver isn't ported to Microblaze. So I don't
- think that's used at all. Remove the entry in features/Makefile and
- the file itself.
-
- - There are a bunch of *-expedite values in features/Makefile for
- architectures for which we don't generate dat files. AFAIK, these
- *-expedite values are only used when generating dat files. Remove
- those that are not necessary.
-
- - 32bit-segments.xml is not listed in the Makfile, but it's used. This
- means that it wouldn't get re-generated if we were to change how C
- files are generated from the XML. It looks like it was simply
- forgotten, add it.

- [gdb/symtab] Fix unhandled dwarf expression opcode with gcc-11 -gdwarf-5
- [ I've confused things by forgetting to add -gdwarf-4 in $subject of
- commit 0057a7ee0d9 "[gdb/testsuite] Add KFAILs for gdb.ada FAILs with
- gcc-11". So I'm adding here -gdwarf-5 in $subject, even though -gdwarf-5 is
- the default for gcc-11. I keep getting confused because of working with a
- system gcc-11 compiler that was patched to switch the default back to
- -gdwarf-4. ]
-
- When running test-case gdb.ada/arrayptr.exp with gcc-11 (and default
- -gdwarf-5), I run into:
- ...
- (gdb) print pa_ptr.all^M
- Unhandled dwarf expression opcode 0xff^M
- (gdb) FAIL: gdb.ada/arrayptr.exp: scenario=all: print pa_ptr.all
- ...
-
- What happens is that pa_ptr:
- ...
- <2><1523>: Abbrev Number: 3 (DW_TAG_variable)
- <1524> DW_AT_name : pa_ptr
- <1529> DW_AT_type : <0x14fa>

- has type:
- ...
- <2><14fa>: Abbrev Number: 2 (DW_TAG_typedef)
- <14fb> DW_AT_name : foo__packed_array_ptr
- <1500> DW_AT_type : <0x1504>
- <2><1504>: Abbrev Number: 4 (DW_TAG_pointer_type)
- <1505> DW_AT_byte_size : 8
- <1505> DW_AT_type : <0x1509>
- ...
- which is a pointer to a subrange:
- ...
- <2><1509>: Abbrev Number: 12 (DW_TAG_subrange_type)
- <150a> DW_AT_lower_bound : 0
- <150b> DW_AT_upper_bound : 0x3fffffffffffffffff
- <151b> DW_AT_name : foo__packed_array
- <151f> DW_AT_type : <0x15cc>
- <1523> DW_AT_artificial : 1
- <1><15cc>: Abbrev Number: 5 (DW_TAG_base_type)
- <15cd> DW_AT_byte_size : 16
- <15ce> DW_AT_encoding : 7 (unsigned)
- <15cf> DW_AT_name : long_long_long_unsigned
- <15d3> DW_AT_artificial : 1
- ...
- with upper bound of form DW_FORM_data16.
-
- In gdb/dwarf/attribute.h we have:
- ...
- /* Return non-zero if ATTR's value falls in the 'constant' class, or
- zero otherwise. When this function returns true, you can apply
- the constant_value method to it.
- ...
- DW_FORM_data16 is not considered as constant_value cannot handle
- that. */
- bool form_is_constant () const;
- ...
- so instead we have attribute::form_is_block (DW_FORM_data16) == true.
-
- Then in attr_to_dynamic_prop for the upper bound, we get a PROC_LOCEXPR
- instead of a PROP_CONST and end up trying to evaluate the constant
- 0x3fffffffffffffffff as if it were a locexpr, which causes the
- "Unhandled dwarf expression opcode 0xff".
-
- In contrast, with -gdwarf-4 we have:
- ...
- <164c> DW_AT_upper_bound : 18 byte block: \
- 9e 10 ff ff ff ff ff ff ff ff 3f 0 0 0 0 0 0 0 \
- (DW_OP_implicit_value 16 byte block: \
- ff ff ff ff ff ff ff ff 3f 0 0 0 0 0 0 0 )
- ...
-
- Fix the dwarf error by translating the DW_FORM_data16 constant into a
- PROC_LOCEXPR, effectively by prepending 0x9e 0x10, such that we have same
- result as with -gdwarf-4:
- ...
- (gdb) print pa_ptr.all^M
- That operation is not available on integers of more than 8 bytes.^M
- (gdb) KFAIL: gdb.ada/arrayptr.exp: scenario=all: print pa_ptr.all \

- PowerPC: ignore sticky options for .machine
- PowerPC gas and objdump for a long time have allowed certain -m/-M
- options that extend a base cpu with extra functional units to be
- specified before the base cpu. For example, "-maltivec -mpower4" is
- the same as "-mpower4 -maltivec". See
- https://sourceware.org/pipermail/binutils/2008-January/054935.html
-
- It doesn't make as much sense that .machine keep any of these
- "sticky" flags when handling a new base cpu. See gcc PR101393. I
- think that instead .machine ought to override the command line.
- That's what this patch does. It is still possible to extend cpu
- functionality with .machine. For example the following can be
- assembled when selecting a basic -mppc on the command line:
- .machine power5
- .machine altivec
- frin 1,2
- lvsr 3,4,5
- Here, ".machine altivec" extends the ".machine power5" so that both
- the power5 "frin" instruction and the altivec "lvsr" instruction are
- enabled. Swapping the two ".machine" directives would result in
- failure to assemble "lvsr".
-
- This change will expose some assembly errors, such as the one in
- glibc/sysdeps/powerpc/powerpc64/tst-ucontext-ppc64-vscr.c, a file
- compiled with -maltivec but containing
- asm volatile (".machine push;\n"
- ".machine \"power5\";\n"
- "vspltisb %0,0;\n"
- "vspltisb %1,-1;\n"
- "vpkuwus %0,%0,%1;\n"
- "mfvscr %0;\n"
- "stvx %0,0,%2;\n"
- ".machine pop;"
- : "=v" (v0), "=v" (v1)
- : "r" (vscr_ptr)
- : "memory");
- It's just wrong to choose power5 for a bunch of altivec instructions
- and in fact all of those .machine directives are unnecessary.
-
- * config/tc-ppc.c (ppc_machine): Don't use command line
- sticky options.

- out some of the non-related fixes in order to get these merged.
-
- This commit addresses two semi-related issues, both of which are
- problems exposed by using 'set debug frame on'.
-
- The first issue is in frame.c in get_prev_frame_always_1, and was
- introduced by this commit:
-
- commit a05a883fbaba69d0f80806e46a9457727fcbe74c
- Date: Tue Jun 29 12:03:50 2021 -0400
-
- gdb: introduce frame_debug_printf
-
- This commit replaced fprint_frame with frame_info::to_string.
- However, the former could handle taking a nullptr while the later, a
- member function, obviously requires a non-nullptr in order to make the
- function call. In one place we are not-guaranteed to have a
- non-nullptr, and so, there is the possibility of triggering undefined
- behaviour.
-
- The second issue addressed in this commit has existed for a while in
- GDB, and would cause this assertion:
-
- gdb/frame.c:622: internal-error: frame_id get_frame_id(frame_info*): Assertion `fi->this_id.p != frame_id_status::COMPUTING' failed.
-
- We attempt to get the frame_id for a frame while we are computing the
- frame_id for that same frame.
-
- What happens is that when GDB stops we create a frame_info object for
- the sentinel frame (frame #-1) and then we attempt to unwind this
- frame to create a frame_info object for frame #0.
-
- In the test case used here to expose the issue we have created a
- Python frame unwinder. In the Python unwinder we attemt to read the
- program counter register.
-
- Reading this register will initially create a lazy register value.
- The frame-id stored in the lazy register value will be for the
- sentinel frame (lazy register values hold the frame-id for the frame
- from which the register will be unwound).
-
- However, the Python unwinder does actually want to examine the value
- of the program counter, and so the lazy register value is resolved
- into a non-lazy value. This sends GDB into value_fetch_lazy_register
- in value.c.
-
- Now, inside this function, if 'set debug frame on' is in effect, then
- we want to print something like:
-
- frame=%d, regnum=%d(%s), ....
-
- Where 'frame=%d' will be the relative frame level of the frame for
- which the register is being fetched, so, in this case we would expect
- to see 'frame=0', i.e. we are reading a register as it would be in
- frame #0. But, remember, the lazy register value actually holds the
- frame-id for frame #-1 (the sentinel frame).
-
- So, to get the frame_info for frame #0 we used to call:
-
- frame = frame_find_by_id (VALUE_FRAME_ID (val));
-
- Where VALUE_FRAME_ID is:
-
- #define VALUE_FRAME_ID(val) (get_prev_frame_id_by_id (VALUE_NEXT_FRAME_ID (val)))
-
- That is, we start with the frame-id for the next frame as obtained by
- VALUE_NEXT_FRAME_ID, then call get_prev_frame_id_by_id to get the
- frame-id of the previous frame.
-
- The get_prev_frame_id_by_id function finds the frame_info for the
- given frame-id (in this case frame #-1), calls get_prev_frame to get
- the previous frame, and then calls get_frame_id.
-
- The problem here is that calling get_frame_id requires that we know
- the frame unwinder, so then have to try each frame unwinder in turn,
- which would include the Python unwinder.... which is where we started,
- and thus we have a loop!
-
- To prevent this loop GDB has an assertion in place, which is what
- actually triggers.
-
- Solving the assertion failure is pretty easy, if we consider the code
- in value_fetch_lazy_register and get_prev_frame_id_by_id then what we
- do is:
-
- 1. Start with a frame_id taken from a value,
- 2. Lookup the corresponding frame,
- 3. Find the previous frame,
- 4. Get the frame_id for that frame, and
- 5. Lookup the corresponding frame
- 6. Print the frame's level
-
- Notice that steps 3 and 5 give us the exact same result, step 4 is
- just wasted effort. We could shorten this process such that we drop
- steps 4 and 5, thus:
-
- 1. Start with a frame_id taken from a value,
- 2. Lookup the corresponding frame,
- 3. Find the previous frame,
- 6. Print the frame's level
-
- This will give the exact same frame as a result, and this is what I
- have done in this patch by removing the use of VALUE_FRAME_ID from
- value_fetch_lazy_register.
-
- Out of curiosity I looked to see how widely VALUE_FRAME_ID was used,
- and saw it was only used in one other place in valops.c:value_assign,
- where, once again, we take the result of VALUE_FRAME_ID and pass it to
- frame_find_by_id, thus introducing a redundant frame_id lookup.
-
- I don't think the value_assign case risks triggering the assertion
- though, as we are unlikely to call value_assign while computing the
- frame_id for a frame, however, we could make value_assign slightly
- more efficient, with no real additional complexity, by removing the
- use of VALUE_FRAME_ID.
-
- So, in this commit, I completely remove VALUE_FRAME_ID, and replace it
- with a use of VALUE_NEXT_FRAME_ID, followed by a direct call to
- get_prev_frame_always, this should make no difference in either case,
- and resolves the assertion issue from value.c.
-
- As I said, this patch was originally part of another series, the
- original test relied on the fixes in that original series. However, I
- was able to create an alternative test for this issue by enabling
- frame debug within an existing test script.
-
- This commit probably fixes bug PR gdb/27938, though the bug doesn't
- have a reproducer attached so it is not possible to know for sure.

- gdb: Fix numerical field extraction for target description "flags"
- The "val_print_type_code_flags ()" function is responsible for
- extraction of fields for "flags" data type. These data types are
- used when describing a custom register type in a target description
- XML. The logic used for the extraction though is not sound:
-
- unsigned field_len = TYPE_FIELD_BITSIZE (type, field);
- ULONGEST field_val
- = val >> (TYPE_FIELD_BITPOS (type, field) - field_len + 1);
-
- TYPE_FIELD_BITSIZE: The bit length of the field to be extracted.
- TYPE_FIELD_BITPOS: The starting position of the field; 0 is LSB.
- val: The register value.
-
- Imagine you have a field that starts at position 1 and its length
- is 4 bits. According to the third line of the code snippet the
- shifting right would become "val >> -2", or "val >> 0xfff...fe"
- to be precise. That will result in a "field_val" of 0.
-
- The correct extraction should be:
-
- ULONGEST field_val = val >> TYPE_FIELD_BITPOS (type, field);
-
- The rest of the algorithm that masks out the higher bits is OK.

- gdb: move remaining ChangeLogs to legacy files
- In commit:
-
- commit f069ea46a03ae868581d1c852da28e979ea1245a
- Date: Sat Jul 3 16:29:08 2021 -0700
-
- Rename gdb/ChangeLog to gdb/ChangeLog-2021
-
- The gdb/ChangeLog file was renamed, but all of the other ChangeLog
- files relating to gdb were left in place.
-
- As I understand things, the no ChangeLogs policy applies to all the
- GDB related directories, so this commit renames all of the remaining
- GDB related ChangeLog files.
-
- As with the original commit, the intention behind this commit is to
- hopefully stop people merging ChangeLog entries by mistake.
-
- The renames carried out in this commit are:
-
- gdb/doc/ChangeLog -> gdb/doc/ChangeLog-1991-2021
- gdb/stubs/ChangeLog -> gdb/stubs/ChangeLog-2012-2020
- gdb/testsuite/ChangeLog -> gdb/testsuite/ChangeLog-2014-2021

- gdb/mi: handle no condition argument case for -break-condition
- As reported in PR gdb/28076 [1], passing no condition argument to the
- -break-condition command (e.g.: "-break-condition 2") should clear the
- condition for breakpoint 2, just like CLI's "condition 2", but instead
- an error message is returned:
-
- ^error,msg="-break-condition: Missing the <number> and/or <expr> argument"
-
- The current implementation of the -break-condition command's argument
- handling (79aabb7308c "gdb/mi: add a '--force' flag to the
- '-break-condition' command") was done according to the documentation,
- where the condition argument seemed mandatory. However, the
- -break-condition command originally (i.e. before the 79aabb7308c
- patch) used the CLI's "cond" command, and back then not passing a
- condition argument was clearing out the condition. So, this is a
- regression in terms of the behavior.
-
- Fix the argument handling of the -break-condition command to allow not
- having a condition argument, and also update the document to make the
- behavior clear. Also add test cases to test the scenarios which were
- previously not covered.

- gdb/testsuite: test get/set value of unregistered Guile parameter
- When creating a parameter in Guile, you have to create it using
- make-parameter and then register it with GDB with register-parameter!.
- In between, it's still possible (though not documented) to set the
- parameter's value. I broke this use case by mistake while writing this
- series, so thought it would be good to have a test for it.
-
- I suppose that people could use this "feature" to give their parameter
- an initial value, even though make-parameter has an initial-value
- parameter for this. Nevertheless, changing this behavior could break
- some scripts, which is why I think it's important for it to be tested.

- gdb: remove cmd_list_element::function::sfunc
- I don't understand what the sfunc function type in
- cmd_list_element::function is for. Compared to cmd_simple_func_ftype,
- it has an extra cmd_list_element parameter, giving the callback access
- to the cmd_list_element for the command being invoked. This allows
- registering the same callback with many commands, and alter the behavior
- using the cmd_list_element's context.
-
- From the comment in cmd_list_element, it sounds like at some point it
- was the callback function type for set and show functions, hence the
- "s". But nowadays, it's used for many more commands that need to access
- the cmd_list_element object (see add_catch_command for example).
-
- I don't really see the point of having sfunc at all, since do_sfunc is
- just a trivial shim that changes the order of the arguments. All
- commands using sfunc could just as well set cmd_list_element::func to
- their callback directly.
-
- Therefore, remove the sfunc field in cmd_list_element and everything
- that goes with it. Rename cmd_const_sfunc_ftype to cmd_func_ftype and
- use it for cmd_list_element::func, as well as for the add_setshow
- commands.

-
- gdb: rename cfunc to simple_func
- After browsing the CLI code for quite a while and trying really hard, I
- reached the conclusion that I can't give a meaningful explanation of
- what "sfunc" and "cfunc" functions are, in cmd_list_element. I don't
- see a logic at all. That makes it very difficult to do any kind of
- change. Unless somebody can make sense out of all that, I'd like to try
- to retro-fit some logic in the cmd_list_element callback function code
- so that we can understand what is going on, do some cleanups and add new
- features.
-
- The first change is about "cfunc". I can't figure out what the "c" in
- cfunc means. It's not const, because there's already "const" in
- "cmd_const_cfunc_ftype", and the previous "cmd_cfunc_ftype" had nothing
- const.. It's not "cmd" or "command", because there's already "cmd" in
- "cmd_const_cfunc_ftype".
-
- The "main" command callback, cmd_list_element::func, has three
- parameters, whereas cfunc has two. It is missing the cmd_list_element
- parameter. So the only reason I see for cfunc to exist is to be a shim
- between the three and two parameter versions. Most commands don't need
- to receive the cmd_list_element object, so adding it everywhere would be
- long and would just add more unnecessary boilerplate. So since this is
- the "simple" version of the callback, compared to the "full", I suggest
- renaming cmd_const_cfunc_ftype into cmd_simple_func_ftype, as well as
- everything (like the utility functions) that goes with it.

- gdb: make inferior::m_args an std::string

-
- gdb: remove inferior::{argc,argv}
- There are currently two states that the inferior args can be stored.
- The main one is the `args` field, where they are stored as a single
- string. The other one is the `argc`/`argv` fields.
-
- This last one is only used for arguments passed in GDB's
- command line. And the only outcome is that when get_inferior_args is
- called, `argc`/`argv` are serialized into `args`. So really,
- `argc`/`argv` is just a staging area before moving the arguments in
- `args`.
-
- Simplify this by only keeping the `args` field. Change
- set_inferior_args_vector to immediately serialize the arguments into
- `args`, work that would be done in get_inferior_args later anyway.
-
- The only time where this work would be "wasted" is when the user passes
- some arguments on the command line, but does not end up running the
- program. But that just seems unlikely. And it's not that much work.

-
- gdb: un-share set_inferior_cwd declaration
- The declaration of set_inferior_cwd is currently shared between gdb and
- gdbserver, in gdbsupport/common-inferior.h. It doesn't need to be, as
- set_inferior_cwd is not called from common code. Only get_inferior_cwd
- needs to.
-
- The motivation for this is that a future patch will change the prototype
- of set_inferior_cwd in gdb, and I don't want to change it for gdbserver
- unnecessarily. I see this as a good cleanup in any case, to reduce to
- just the essential what is shared between GDB and GDBserver.

-
- gdb/testsuite: don't error when trying to unset last_spawn_tty_name
- In spawn_capture_tty_name (lib/gdb.exp) we either set or unset
- last_spawn_tty_name depending on whether spawn_out(slave,name) exists
- or not.
-
- One situation that might cause spawn_out(slave,name) to not exists is
- if the spawn function is called with the argument -leaveopen, which is
- how it is called when processes are created as part of a pipeline, the
- created process has no tty, instead its output is written to a file
- descriptor.
-
- If a pipeline is created consisting of multiple processes then there
- will be multiple sequential calls to spawn, all using -leaveopen. The
- first of these calls is fine, spawn_out(slave,name) is not set, and so
- in spawn_capture_tty_name we unset last_spawn_tty_name. However, on
- the second call to spawn, spawn_out(slave,name) is still not set and
- so in spawn_capture_tty_name we again try to unset
- last_spawn_tty_name, this now throws an error (as last_spawn_tty_name
- is already unset).
-
- Fix this issue by using -nocomplain with the call to unset in
- spawn_capture_tty_name.
-
- Before this commit I was seeing gdb.base/gnu-debugdata.exp report 1
- pass, and 1 unsupported test. After this commit I now see 16 passes
- from this test script.
-
- I have also improved the code that used to do this:
-
- if { [info exists spawn_out] } {
- set ::last_spawn_tty_name $spawn_out(slave,name)
- } else {
- ...
- }
-
- The problem here is that we check for the existence of spawn_out, and
- then unconditionally read spawn_out(slave,name). A situation could
- arise where some other element of spawn_out is set,
- e.g. spawn_out(foo), in which case we would enter the if block and try
- to read a non-existent variable. After this commit we now check
- specifically for spawn_out(slave,name).
-
- Finally, it is worth noting that before this issue was fixed runtest
- itself, or rather the expect process behind runtest, would segfault
- while exiting. I haven't looked at all into what the problem is here
- that caused expect to crash, as fixing the bug in GDB's testing
- scripts made the segfault go away.

- x86: drop dq{b,d}_mode
- Their sole use is for {,V}EXTRACTPS / {,V}P{EXT,INS}RB respectively; for
- consistency also limit use of dqw_mode to Jdqw. 64-bit disassembly
- reflecting REX.W / VEX.W is not in line with the assembler's opcode
- table having NoRex64 / VexWIG in all respective templates, i.e. assembly
- input isn't being honored there either. Obviously the 0FC5 encodings of
- {,V}PEXTRW then also need adjustment for consistency reasons.
-
- x86: drop vex_scalar_w_dq_mode
- It has only a single use and can easily be represented by dq_mode
- instead. Plus its handling in intel_operand_size() was duplicating
- that of vex_vsib_{d,q}_w_dq_mode anyway.
-
- x86: drop xmm_m{b,w,d,q}_mode
- They're effectively redundant with {b,w,d,q}_mode.
-
- x86: fold duplicate vector register printing code
- The bulk of OP_XMM() can be easily reused also for OP_EX(). Break the
- shared logic out of the function, and invoke the new helper from both
- places.
-
- x86: drop vex_mode and vex_scalar_mode
- These are fully redundant with, respectively, x_mode and scalar_mode.
-
- x86: correct EVEX.V' handling outside of 64-bit mode
- Unlike the high bit of VEX.vvvv / EVEX.vvvv, EVEX.V' is not ignored
- outside of 64-bit mode. Oddly enough there already are tests for these
- cases, but their expectations were wrong. (This may have been based on
- an old SDM version, where the restriction wasn't properly spelled out.)
-
- x86: fold duplicate code in MOVSXD_Fixup()
- There's no need to have two paths printing the "xd" mnemonic suffix.
-
- x86: fold duplicate register printing code
- What so far was OP_E_register() can be easily reused also for OP_G().
- Add suitable parameters to the function and move the invocation of
- swap_operand() to OP_E(). Adjust MOVSXD's first operand: There never was
- a need to use movsxd_mode there, and its use gets in the way of the code
- folding.
-
- x86-64: properly bounds-check %bnd<N> in OP_G()
- The restriction to %bnd0-%bnd3 requires to also check REX.R is clear,
- just like OP_E_Register() also includes REX.B in its check.
-
- x86-64: generalize OP_G()'s EVEX.R' handling
- EVEX.R' is invalid to be clear not only for mask registers, but also for
- GPRs - IOW everything handled in this function.

-
- x86: correct VCVT{,U}SI2SD rounding mode handling
- With EVEX.W clear the instruction doesn't ignore the rounding mode, but
- (like for other insns without rounding semantics) EVEX.b set causes #UD.
- Hence the handling of EVEX.W needs to be done when processing
- evex_rounding_64_mode, not at the decode stages.
-
- Derive a new 64-bit testcase from the 32-bit one to cover the different
- EVEX.W treatment in both cases.

- as_bad_subtract
- Many places report errors of the nature "can't resolve a - b".
- This provides a utility function to report such errors consistently.
- I removed the section reporting and quotes around symbol names while I
- was at it. Compare
- ifunc-2.s:4: Error: can't resolve `bar1' {.text.1 section} - `foo1' {.text.1 section}
- with
- ifunc-2.s:4: Error: can't resolve bar1 - foo1
-
- In many cases the section names don't help the user very much in
- figuring out what went wrong, and the quotes if present arguably ought
- to be placed around the entire expression:

- Remove `netbsdpe` support
- netbsdpe was deprecated in c2ce831330e10dab4703094491f80b6b9a5c2289.
- Since then, a release has passed (2.37), and it was marked obselete in
- 5c9cbf07f3f972ecffe13d858010b3179df17b32. Unless I am mistaken, that
- means we can now remove support altogether.
-
- All branches in the "active" code are remove, and the target is
- additionally marked as obsolete next to the other removed ones for
- libbfd and gdb.
-
- Per [1] from the NetBSD toolchain list, PE/COFF support was removed a
- decade ago. Furthermore, the sole mention of this target in the binutils
- commit history was in 2002. Together, I'm led to believe this target
- hasn't seen much attention in quite a while.

- Fix printing of non-address types when memory tagging is enabled
- When the architecture supports memory tagging, we handle
- pointer/reference types in a special way, so we can validate tags and
- show mismatches.
-
- Unfortunately, the currently implementation errors out when the user
- prints non-address values: composite types, floats, references, member
- functions and other things.
-
- Vector registers:
-
- (gdb) p $v0
- Value can't be converted to integer.
-
- Non-existent internal variables:
-
- (gdb) p $foo
- Value can't be converted to integer.
-
- The same happens for complex types and printing struct/union types.
-
- There are a few problems here.
-
- The first one is that after print_command_1 evaluates the expression
- to print, the tag validation code call value_as_address
- unconditionally, without making sure we have have a suitable type
- where it makes to sense to call it. That results in value_as_address
- (if it isn't given a pointer-like type) trying to treat the value as
- an integer and convert it to an address, which #1 - doesn't make sense
- (i.e., no sense in validating tags after "print 1"), and throws for
- non-integer-convertible types. We fix this by making sure we have a
- pointer or reference type first, and only if so then proceed to check
- if the address-like value has tags.
-
- The second is that we're calling value_as_address even if we have an
- optimized out or unavailable value, which throws, because the value's
- contents aren't fully accessible/readable. This error currently
- escapes out and aborts the print. This case is fixed by checking for
- optimized out / unavailable explicitly.
-
- Third, the tag checking process does not gracefully handle exceptions.
- If any exception is thrown from the tag validation code, we abort the
- print. E.g., the target may fail to access tags via a running thread.
- Or the needed /proc files aren't available. Or some other untold
- reason. This is a bit too rigid. This commit changes print_command_1
- to catch errors, print them, and still continue with the normal
- expression printing path instead of erroring out and printing nothing
- useful.
-
- With this patch, printing works correctly again:

- RISC-V: Minor updates for architecture parser.
- * Two add subset functions is redundant. Keep the riscv_add_implicit_subset,
- and renamed it to riscv_add_subset. Besides, if the subset is added in order,
- then we just add it at the tail of the subset list.
-
- * Removed the "-march:" prefix from the error messages. Since not only the
- -march= option will use the parser, but also the architecture elf attributes,
- the default architecture setting and linker will use the same parser.
-
- * Use a function, riscv_parse_check_conflicts, to check the conflicts
- of extensions, including the rv64e and rv32q.

- At frame 45, the new_thread observable is fired. At this moment, the
- new thread isn't the current thread, inferior_ptid is null_ptid. I
- think this is ok: the new_thread observable doesn't give any guarantee
- on the global context when observers are invoked. Frame 35,
- btrace_compute_ftrace_bts, calls gdb_insn_length. gdb_insn_length
- doesn't have a thread_info or other parameter what could indicate where
- to read memory from, it implicitly uses the global context
- (inferior_ptid).
-
- So we reach the all_non_exited_threads_range in
- record_btrace_target::record_is_replaying with a null inferior_ptid.
- The previous implemention of all_non_exited_threads_range didn't care,
- but the new one does. The problem of calling gdb_insn_length and
- ultimately trying to read memory with a null inferior_ptid already
- existed, but the commit mentioned above made it visible.
-
- Something between frames 40 (record_btrace_enable_warn) and 35
- (btrace_compute_ftrace_bts) needs to be switching the global context to
- make TP the current thread. Since btrace_compute_ftrace_bts takes the
- thread_info to work with as a parameter, that typically means that it
- doesn't require its caller to also set the global current context
- (current thread) when calling. If it needs to call other functions
- that do require the global current thread to be set, then it needs to
- temporarily change the current thread while calling these other
- functions. Therefore, switch and restore the current thread in
- btrace_compute_ftrace_bts.
-
- By inspection, it looks like btrace_compute_ftrace_pt may also call
- functions sensitive to the global context: it installs the
- btrace_pt_readmem_callback callback in the PT instruction decoder. When
- this function gets called, inferior_ptid must be set appropriately. Add
- a switch and restore in there too.

- Fix file-name handling regression with DWARF index
- When run with the gdb-index or debug-names target boards, dup-psym.exp
- fails. This came up for me because my new DWARF scanner reuses this
- part of the existing index code, and so it registers as a regression.
- This is PR symtab/25834.
-
- Looking into this, I found that the DWARF index code here is fairly
- different from the psymtab code. I don't think there's a deep reason
- for this, and in fact, it seemed to me that the index code could
- simply mimic what the psymtab code already does.
-
- That is what this patch implements. The DW_AT_name and DW_AT_comp_dir
- are now stored in the quick file names table. This may require
- allocating a quick file names table even when DW_AT_stmt_list does not
- exist. Then, the functions that work with this data are changed to
- use find_source_or_rewrite, just as the psymbol code does. Finally,
- line_header::file_full_name is removed, as it is no longer needed.
-
- Currently, the index maintains a hash table of "quick file names".
- The hash table uses a deletion function to free the "real name"
- components when necessary. There's also a second such function to
- implement the forget_cached_source_info method.
-
- This bug fix patch will create a quick file name object even when
- there is no DW_AT_stmt_list, meaning that the object won't be entered
- in the hash table. So, this patch changes the memory management
- approach so that the entries are cleared when the per-BFD object is
- destroyed. (A dwarf2_per_cu_data destructor is not introduced,
- because we have been avoiding adding a vtable to that class.)

-
- Check for debug-types in map_symbol_filenames
- map_symbol_filenames can skip type units -- in fact I think it has to,
- due to the assertion at the top of dw2_get_file_names. This may be a
- regression due to the TU/CU unification patch, I did not check.
-
- Simplify DWARF file name caching
- The DWARF index file name caching code only records when a line table
- has been read and the reading failed. However, the code would be
- simpler if it recorded any attempt, which is what this patch
- implements.
-
- Introduce find_source_or_rewrite
- The final bug fix in this series would duplicate the logic in
- psymtab_to_fullname, so this patch extracts the body of this function
- into a new function.
-
- Simplify file_and_directory storage management
- file_and_directory carries a std::string in case the compilation
- directory is computed, but a subsequent patch wants to preserve this
- string without also having to maintain the storage for it. So, this
- patch arranges for the compilation directory string to be stored in
- the per-BFD string bcache instead.
-
- Pass file_and_directory through DWARF line-decoding code
- This patch removes the redundant "comp_unit" parameter from
- compute_include_file_name, and arranges to pass a file_and_directory
- object from the readers down to this function. It also changes the
- partial symtab reader to use find_file_and_directory, rather than
- reimplement this functionality by hand.
-
- Rename and refactor psymtab_include_file_name
- In order to fix an index-related regression, I want to use
- psymtab_include_file_name in the DWARF index file-handling code. This
- patch renames this function and changes it to no longer require a
- partial symtab to be passed in. A subsequent patch will further
- refactor this code to remove the redundant parameter (which was always
- there but is now more obvious).

-

-
- We actually need to pass down the list on which we want to iterator
- (that is the inferior_list global), so that all_inferiors_iterator's

- filter. In this case, we don't do any filtering, but if in the future
- all_inferiors_safe needed to allow filtering on process target (like
- all_inferiors does), we could pass down a process target pointer.
-
- basic_safe_iterator's constructor needs to be changed to allow

-
- With this, gdb.threads/fork-plus-threads.exp is passing once again for

- Fix array stride bug
- Investigation of using the Python API with an Ada program showed that
- an array of dynamic types was not being handled properly. I tracked
- this down to an oddity of how array strides are handled.
-
- In gdb, an array stride can be attached to the range type, via the
- range_bounds object. However, the stride can also be put into the
- array's first field. From create_range_type_with_stride:
-
- else if (bit_stride > 0)
- TYPE_FIELD_BITSIZE (result_type, 0) = bit_stride;
-
- It's hard to be sure why this is done, but I would guess a combination
- of historical reasons plus a desire (mentioned in a comment somewhere)
- to avoid modifying the range type.
-
- This patch fixes the problem by changing type::bit_stride to
- understand this convention. It also fixes one spot that reproduces
- this logic.

- Avoid expression parsing crash with unknown language
- PR gdb/28093 points out that gdb crashes when language is set to

- gdb: call post_create_inferior at end of follow_fork_inferior
- GDB doesn't handle well the case of an inferior using the JIT interface
- to register JIT-ed objfiles and forking. If an inferior registers a
- code object using the JIT interface and then forks, the child process
- conceptually has the same code object loaded, so GDB should look it up
- and learn about it (it currently doesn't).
-
- To achieve this, I think it would make sense to have the
- inferior_created observable called when an inferior is created due to a
- fork in follow_fork_inferior. The inferior_created observable is
- currently called both after starting a new inferior and after attaching
- to an inferior, allowing various sub-components to learn about that new
- executing inferior. We can see handling a fork child just like
- attaching to it, so any work done when attaching should also be done in
- the case of a fork child.
-
- Instead of just calling the inferior_created observable, this patch
- makes follow_fork_inferior call the whole post_create_inferior function.
- This way, the attach and follow-fork code code paths are more alike.
-
- Given that post_create_inferior calls solib_create_inferior_hook,
- follow_fork_inferior doesn't need to do it itself, so those calls to
- solib_create_inferior_hook are removed.
-
- One question you may have: why not just call post_create_inferior at the
- places where solib_create_inferior_hook is currently called, instead of
- after target_follow_fork?
-
- - there's something fishy for the second solib_create_inferior_hook
- call site: at this point we have switched the current program space
- to the child's, but not the current inferior nor the current thread.
- So solib_create_inferior_hook (and everything under, including
- check_for_thread_db, for example) is called with inferior 1 as the
- current inferior and inferior 2's program space as the current
- program space. I think that's wrong, because at this point we are
- setting up inferior 2, and all that code relies on the current
- inferior. We could just add a switch_to_thread call before it to
- make inferior 2 the current one, but there are other problems (see
- below).
-
- - solib_create_inferior_hook is currently not called on the
- `follow_child && detach_fork` path. I think we need to call it,
- because we still get a new inferior in that case (even though we
- detach the parent). If we only call post_create_inferior where
- solib_create_inferior_hook used to be called, then the JIT
- subcomponent doesn't get informed about the new inferior, and that
- introduces a failure in the new gdb.base/jit-elf-fork.exp test.
-
- - if we try to put the post_create_inferior just after the
- switch_to_thread that was originally at line 662, or just before the
- call to target_follow_fork, we introduce a subtle failure in
- gdb.threads/fork-thread-pending.exp. What happens then is that
- libthread_db gets loaded (somewhere under post_create_inferior)
- before the linux-nat target learns about the LWPs (which happens in
- linux_nat_target::follow_fork). As a result, the ALL_LWPS loop in
- try_thread_db_load_1 doesn't see the child LWP, and the thread-db
- target doesn't have the chance to fill in thread_info::priv. A bit
- later, when the test does "info threads", and
- thread_db_target::pid_to_str is called, the thread-db target doesn't
- recognize the thread as one of its own, and delegates the request to
- the target below. Because the pid_to_str output is not the expected
- one, the test fails.
-
- This tells me that we need to call the process target's follow_fork
- first, to make the process target create the necessary LWP and thread
- structures. Then, we can call post_create_inferior to let the other
- components of GDB do their thing.
-
- But then you may ask: check_for_thread_db is already called today,
- somewhere under solib_create_inferior_hook, and that is before
- target_follow_fork, why don't we see this ordering problem!? Well,
- because of the first bullet point: when check_for_thread_db /
- thread_db_load are called, the current inferior is (erroneously)
- inferior 1, the parent. Because libthread_db is already loaded for
- the parent, thread_db_load early returns. check_for_thread_db later
- gets called by linux_nat_target::follow_fork. At this point, the
- current inferior is the correct one and the child's LWP exists, so
- all is well.
-
- Since we now call post_create_inferior after target_follow_fork, which
- calls the inferior_created observable, which calls check_for_thread_db,
- I don't think linux_nat_target needs to explicitly call
- check_for_thread_db itself, so that is removed.
-
- In terms of testing, this patch adds a new gdb.base/jit-elf-fork.exp
- test. It makes an inferior register a JIT code object and then fork.
- It then verifies that whatever the detach-on-fork and follow-fork-child
- parameters are, GDB knows about the JIT code object in all the inferiors
- that survive the fork. It verifies that the inferiors can unload that
- code object.
-
- There isn't currently a way to get visibility into GDB's idea of the JIT
- code objects for each inferior. For the purpose of this test, add the
- "maintenance info jit" command. There isn't much we can print about the
- JIT code objects except their load address. So the output looks a bit
- bare, but it's good enough for the test.

- gas: default TC_VALIDATE_FIX_SUB to 0
- gas/write.c provides a fallback TC_VALIDATE_FIX_SUB define that can be
- a problem for some targets, the problem being that a non-zero
- definition of TC_VALIDATE_FIX_SUB says that some uses of fx_subsy are
- OK, in effect that the target will handle fx_subsy in md_apply_fix
- and/or tc_gen_reloc. A lot of targets don't have the necessary
- md_apply_fix and tc_gen_reloc support. So a safer default is to
- disallow fx_subsy by default.
-
- I've had a good look over target usage of fx_subsy, and think I've
- caught all the cases where targets need TC_VALIDATE_FIX_SUB. Possible
- failures would be limited to alpha, microblaze, ppc and s390 (the
- targets that define UNDEFINED_DIFFERENCE_OK), or targets that generate
- fixups with BFD_RELOC_GPREL32/16 and use a syntax explicitly showing
- a difference expression.

- [gdb/testsuite] Fix gdb.base/gold-gdb-index.exp
- When running test-case gdb.base/gold-gdb-index.exp on openSUSE Tumbleweed,
- I run into:
- ...
- FAIL: gdb.base/gold-gdb-index.exp: maint info symtabs
- ...
-
- This is due to a dummy .gdb_index:
- ...
- Contents of the .gdb_index section:
-
- Version 7
-
- CU table:
-
- TU table:
-
- Address table:
-
- Symbol table:
- ...
-
- The dummy .gdb_index is ignored when loading the symbols, and instead partial
- symbols are used. Consequently, we get the same result as if we'd removed
- -Wl,--gdb-index from the compilation.
-
- Presumably, gold fails to generate a proper .gdb_index because it lacks
- DWARF5 support.
-
- Anyway, without a proper .gdb_index we can't test the gdb behaviour we're
- trying to excercise. Fix this by detecting whether we actually used a
- .gdb_index for symbol loading.

-
- That's a dtor, thus noexcept. That's the reason for the
- std::terminate.
-
- The previous patch fixed things such that the exception above isn't
- thrown anymore. However, it's possible that e.g., the remote
- connection drops just while a user types "nosharedlibrary", or some
- other reason that leads to objfile::~objfile, and then we end up the
- same std::terminate problem.
-
- Also notice that frames #9-#11 are BFD frames:
-

-
- BFD is written in C and thus throwing exceptions over such frames may
- either not clean up properly, or, may abort if bfd is not compiled
- with -fasynchronous-unwind-tables (x86-64 defaults that on, but not
- all GCC ports do).
-
- Thus frame #8 seems like a good place to swallow exceptions. More so
- since in this spot we already ignore target_fileio_close return
- errors. That's what this commit does. Without the previous fix, we'd
- see:
-
- (gdb) detach
- Detaching from program: target:/any/program, process 2197701
- Ending remote debugging.

-
- So frame #28 already detached the remote process, and then we're
- purging the shared libraries. GDB had opened remote shared libraries
- via the target: sysroot, so it tries closing them. GDBserver is
- tearing down already, so remote communication breaks down and we close
- the remote target and throw TARGET_CLOSE_ERROR.
-
- Note frame #14:
-
- #14 0x0000555555ae4730 in objfile::~objfile (this=0x555556515540, __in_chrg=<optimized out>) at src/gdb/objfiles.c:573
-
- That's a dtor, thus noexcept. That's the reason for the
- std::terminate.
-
- Stepping back a bit, why do we still have open remote files if we've
- managed to detach already, and, we're debugging with "target remote"?
- The reason is that commit 408f66864a1a823591b26420410c982174c239a2
- makes detach_command hold a reference to the target, so the remote
- target won't be finally closed until frame #28 returns. It's closing
- the target that invalidates target file I/O handles.
-
- This commit fixes the issue by not relying on target_close to
- invalidate the target file I/O handles, instead invalidate them
- immediately in remote_unpush_target. So when GDB purges the solibs,
- and we end up in target_fileio_close (frame #7 above), there's nothing
- to do, and we don't try to talk with the remote target anymore.
-
- The regression isn't seen when testing with
- --target_board=native-gdbserver, because that does "set sysroot" to
- disable the "target:" sysroot, for test run speed reasons. So this
- commit adds a testcase that explicitly tests detach with "set sysroot
- target:".

- [gdb/testsuite] Fix check-libthread-db.exp FAILs with glibc 2.33
- When running test-case gdb.threads/check-libthread-db.exp on openSUSE
- Tumbleweed with glibc 2.33, I get:
- ...
- (gdb) maint check libthread-db^M
- Running libthread_db integrity checks:^M
- Got thread 0x7ffff7c79b80 => 9354 => 0x7ffff7c79b80; errno = 0 ... OK^M
- libthread_db integrity checks passed.^M
- (gdb) FAIL: gdb.threads/check-libthread-db.exp: user-initiated check: \
- libpthread.so not initialized (pattern 2)
- ...
-
- The test-case expects instead:
- ...
- Got thread 0x0 => 9354 => 0x0 ... OK^M
- ...
- which is what I get on openSUSE Leap 15.2 with glibc 2.26, and what is
- described in the test-case like this:
- ...
- # libthread_db should fake a single thread with th_unique == NULL.
- ...
-
- Using a breakpoint on check_thread_db_callback we can compare the two
- scenarios, and find that in the latter case we hit this code in glibc function
- iterate_thread_list in nptl_db/td_ta_thr_iter.c:
- ...
- if (next == 0 && fake_empty)
- {
- /* __pthread_initialize_minimal has not run. There is just the main
- thread to return. We cannot rely on its thread register. They
- sometimes contain garbage that would confuse us, left by the
- kernel at exec. So if it looks like initialization is incomplete,
- we only fake a special descriptor for the initial thread. */
- td_thrhandle_t th = { ta, 0 };
- return callback (&th, cbdata_p) != 0 ? TD_DBERR : TD_OK;
- }
- ...
- while in the former case we don't because this preceding statement doesn't
- result in next == 0:
- ...
- err = DB_GET_FIELD (next, ta, head, list_t, next, 0);
- ...
-
- Note that the comment mentions __pthread_initialize_minimal, but in both cases
- it has already run before we hit the callback, so it's possible the comment is
- no longer accurate.
-
- The change in behaviour bisect to glibc commit 1daccf403b "nptl: Move stack
- list variables into _rtld_global", which moves the initialization of stack
- list variables such as __stack_user to an earlier moment, which explains well
- enough the observed difference.
-
- Fix this by updating the regexp patterns to agree with what libthread-db is
- telling us.
-
- Tested on x86_64-linux, both with glibc 2.33 and 2.26.

- gdb: disable commit-resumed on -exec-interrupt --thread-group

-
- This is because this code path never disables commit-resumed (a
- requirement for calling target_stop, as documented in
- process_stratum_target::»commit_resumed_state) before calling
- target_stop.
-
- The other 3 code paths in mi_cmd_exec_interrupt use interrupt_target_1,
- which does it. But the --thread-group code path uses its own thing
- which doesn't do it. Fix this by adding a scoped_disable_commit_resumed
- in this code path.
-
- Calling -exec-interrupt with --thread-group is apparently not tested at
- the moment (which is why this bug could creep in). Add a new test for
- that. The test runs two inferiors and tries to interrupt them with
- "-exec-interrupt --thread-group X".

- gdb: optimize all_matching_threads_iterator
- all_matching_threads_iterator is used extensively in some pretty fast
- paths, often under the all_non_exited_threads function.
-
- If a filter target and thread-specific ptid are given, it iterates on
- all threads of all inferiors of that target, to ultimately yield exactly
- on thread. And this happens quite often, which means we unnecessarily
- spend time iterating on threads to find the one we are looking for. The
- same thing happens if an inferior-specific ptid is given, although there
- the iterator yields all the threads of that inferior.
-
- In those cases, the callers of all_non_exited_threads could have
- different behaviors depending on the kind of ptid, to avoid this
- inefficiency, but that would be very tedious. Using
- all_non_exited_threads has the advantage that one simple implementation
- can work seamlessly on multiple threads or on one specific thread, just
- by playing with the ptid.
-
- Instead, optimize all_matching_threads_iterator directly to detect these
- different cases and limiting what we iterate on to just what we need.
-
- - if filter_ptid is minus_one_ptid, do as we do now: filter inferiors
- based on filter_target, iterate on all of the matching inferiors'
- threads
- - if filter_ptid is a pid-only ptid (then a filter_target must
- necessarily be given), look up that inferior and iterate on all its
- threads
- - otherwise, filter_ptid is a thread-specific ptid, so look up that
- specific thread and "iterate" only on it
-
- For the last case, what was an iteration on all threads of the filter
- target now becomes a call to find_thread_ptid, which is quite efficient
- now thanks to inferior::ptid_thread_map.

- When debugging a large number of threads (thousands), looking up a

- Add inferior::thread_map, an std::unordered_map indexed by ptid_t, and
- change the find_thread_ptid function to look up a thread using

- gdb: optimize selection of resumed thread with pending event
- Consider a case where many threads (thousands) keep hitting a breakpoint
- whose condition evaluates to false. random_pending_event_thread is
- responsible for selecting a thread from an inferior among all that are
- resumed with a pending wait status. It is currently implemented by
- walking the inferior's thread list twice: once to count the number of
- candidates and once to select a random one.
-
- Since we now maintain a per target list of resumed threads with pending
- event, we can implement this more efficiently by walking that list and
- selecting the first thread that matches the criteria
- (random_pending_event_thread looks for an thread from a specific
- inferior, and possibly a filter ptid). It will be faster especially in
- the common case where there isn't any resumed thread with pending
- event. Currently, we have to iterate the thread list to figure this
- out. With this patch, the list of resumed threads with pending event
- will be empty, so it's quick to figure out.
-
- The random selection is kept, but is moved to
- process_stratum_target::random_resumed_with_pending_wait_status. The
- same technique is used: do a first pass to count the number of
- candidates, and do a second pass to select a random one. But given that
- the list of resumed threads with pending wait statuses will generally be
- short, or at least shorter than the full thread list, it should be
- quicker.
-
- Note that this isn't completely true, in case there are multiple
- inferiors on the same target. Imagine that inferior A has 10k resumed
- threads with pending wait statuses, and random_pending_event_thread is
- called with inferior B. We'll need to go through the list that contains
- inferior A's threads to realize that inferior B has no resumed threads
- with pending wait status. But I think that this is a corner /
- pathological case. And a possible fix for this situation would be to
- make random_pending_event_thread work per-process-target, rather than
- per-inferior.

- gdb: optimize check for resumed threads with pending wait status in maybe_set_commit_resumed_all_targets
- Consider a test case where many threads (thousands) keep hitting a
- breakpoint whose condition evaluates to false.
- maybe_set_commit_resumed_all_targets is called at each handled event,
- when the scoped_disable_commit_resumed object in fetch_inferior_event is
- reset_and_commit-ed. One particularly expensive check in there is
- whether the target has at least one resumed thread with a pending wait
- status (in which case, we don't want to commit the resumed threads, as
- we want to consume this status first). It is currently implemented as
- walking all threads of the target.
-
- Since we now maintain a per-target list of resumed threads with pending
- status, we can do this check efficiently, by checking whether that list
- is empty or not.

- gdb: maintain per-process-target list of resumed threads with pending wait status
- Looking up threads that are both resumed and have a pending wait
- status to report is something that we do quite often in the fast path
- and is expensive if there are many threads, since it currently requires
- walking whole thread lists.
-
- The first instance is in maybe_set_commit_resumed_all_targets. This is
- called after handling each event in fetch_inferior_event, to see if we
- should ask targets to commit their resumed threads or not. If at least
- one thread is resumed but has a pending wait status, we don't ask the
- targets to commit their resumed threads, because we want to consume and
- handle the pending wait status first.
-
- The second instance is in random_pending_event_thread, where we want to
- select a random thread among all those that are resumed and have a
- pending wait status. This is called every time we try to consume
- events, to see if there are any pending events that we we want to
- consume, before asking the targets for more events.
-
- To allow optimizing these cases, maintain a per-process-target list of
- threads that are resumed and have a pending wait status.
-
- In maybe_set_commit_resumed_all_targets, we'll be able to check in O(1)
- if there are any such threads simply by checking whether the list is
- empty.

- In random_pending_event_thread, we'll be able to use that list, which
- will be quicker than iterating the list of threads, especially when
- there are no resumed with pending wait status threads.
-
- About implementation details: using the new setters on class
- thread_info, it's relatively easy to maintain that list. Any time the
- "resumed" or "pending wait status" property is changed, we check whether
- that should cause the thread to be added or removed from the list.
-
- In set_thread_exited, we try to remove the thread from the list, because
- keeping an exited thread in that list would make no sense (especially if
- the thread is freed). My first implementation assumed that a process
- stratum target was always present when set_thread_exited is called.
- That's however, not the case: in some cases, targets unpush themselves
- from an inferior and then call "exit_inferior", which exits all the
- threads. If the target is unpushed before set_thread_exited is called
- on the threads, it means we could mistakenly leave some threads in the
- list. I tried to see how hard it would be to make it such that targets
- have to exit all threads before unpushing themselves from the inferior
- (that would seem logical to me, we don't want threads belonging to an
- inferior that has no process target). That seemed quite difficult and
- not worth the time at the moment. Instead, I changed
- inferior::unpush_target to remove all threads of that inferior from the
- list.
-
- As of this patch, the list is not used, this is done in the subsequent
- patches.
-
- The debug messages in process-stratum-target.c need to print some ptids.
- However, they can't use target_pid_to_str to print them without
- introducing a dependency on the current inferior (the current inferior
- is used to get the current target stack). For debug messages, I find it
- clearer to print the spelled out ptid anyway (the pid, lwp and tid
- values). Add a ptid_t::to_string method that returns a string
- representation of the ptid that is meant for debug messages, a bit like
- we already have frame_id::to_string.

- gdb: make thread_info::suspend private, add getters / setters
- A following patch will want to take some action when a pending wait
- status is set on or removed from a thread. Add a getter and a setter on
- thread_info for the pending waitstatus, so that we can add some code in
- the setter later.
-
- The thing is, the pending wait status field is in the
- thread_suspend_state, along with other fields that we need to backup
- before and restore after the thread does an inferior function call.
- Therefore, make the thread_suspend_state member private
- (thread_info::suspend becomes thread_info::m_suspend), and add getters /
- setters for all of its fields:
-
- - pending wait status
- - stop signal
- - stop reason
- - stop pc
-
- For the pending wait status, add the additional has_pending_waitstatus
- and clear_pending_waitstatus methods.
-
- I think this makes the thread_info interface a bit nicer, because we
- now access the fields as:
-
- thread->stop_pc ()
-
- rather than
-
- thread->suspend.stop_pc
-
- The stop_pc field being in the `suspend` structure is an implementation
- detail of thread_info that callers don't need to be aware of.
-
- For the backup / restore of the thread_suspend_state structure, add
- save_suspend_to and restore_suspend_from methods. You might wonder why
- `save_suspend_to`, as opposed to a simple getter like
-
- thread_suspend_state &suspend ();
-
- I want to make it clear that this is to be used only for backing up and
- restoring the suspend state, _not_ to access fields like:
-
- thread->suspend ()->stop_pc
-
- Adding some getters / setters allows adding some assertions. I find
- that this helps understand how things are supposed to work. Add:
-
- - When getting the pending status (pending_waitstatus method), ensure
- that there is a pending status.
- - When setting a pending status (set_pending_waitstatus method), ensure
- there is no pending status.
-
- There is one case I found where this wasn't true - in
- remote_target::process_initial_stop_replies - which needed adjustments
- to respect that contract. I think it's because
- process_initial_stop_replies is kind of (ab)using the
- thread_info::suspend::waitstatus to store some statuses temporarily, for
- its internal use (statuses it doesn't intent on leaving pending).
-
- process_initial_stop_replies pulls out stop replies received during the
- initial connection using target_wait. It always stores the received
- event in `evthread->suspend.waitstatus`. But it only sets
- waitstatus_pending_p, if it deems the event interesting enough to leave
- pending, to be reported to the core:
-
- if (ws.kind != TARGET_WAITKIND_STOPPED
- || ws.value.sig != GDB_SIGNAL_0)
- evthread->suspend.waitstatus_pending_p = 1;
-
- It later uses this flag a bit below, to choose which thread to make the
- "selected" one:
-
- if (selected == NULL
- && thread->suspend.waitstatus_pending_p)
- selected = thread;
-
- And ultimately that's used if the user-visible mode is all-stop, so that
- we print the stop for that interesting thread:
-
- /* In all-stop, we only print the status of one thread, and leave
- others with their status pending. */
- if (!non_stop)
- {
- thread_info *thread = selected;
- if (thread == NULL)
- thread = lowest_stopped;
- if (thread == NULL)
- thread = first;
-
- print_one_stopped_thread (thread);
- }
-
- But in any case (all-stop or non-stop), print_one_stopped_thread needs
- to access the waitstatus value of these threads that don't have a
- pending waitstatus (those that had TARGET_WAITKIND_STOPPED +
- GDB_SIGNAL_0). This doesn't work with the assertions I've
- put.
-
- So, change the code to only set the thread's wait status if it is an
- interesting one that we are going to leave pending. If the thread
- stopped due to a non-interesting event (TARGET_WAITKIND_STOPPED +
- GDB_SIGNAL_0), don't store it. Adjust print_one_stopped_thread to
- understand that if a thread has no pending waitstatus, it's because it
- stopped with TARGET_WAITKIND_STOPPED + GDB_SIGNAL_0.
-
- The call to set_last_target_status also uses the pending waitstatus.
- However, given that the pending waitstatus for the thread may have been
- cleared in print_one_stopped_thread (and that there might not even be a
- pending waitstatus in the first place, as explained above), it is no
- longer possible to do it at this point. To fix that, move the call to
- set_last_target_status in print_one_stopped_thread. I think this will
- preserve the existing behavior, because set_last_target_status is
- currently using the current thread's wait status. And the current
- thread is the last one for which print_one_stopped_thread is called. So
- by calling set_last_target_status in print_one_stopped_thread, we'll get
- the same result. set_last_target_status will possibly be called
- multiple times, but only the last call will matter. It just means
- possibly more calls to set_last_target_status, but those are cheap.

- gdb: use intrusive list for step-over chain
- The threads that need a step-over are currently linked using an
- hand-written intrusive doubly-linked list, so that seems a very good
- candidate for intrusive_list, convert it.
-
- For this, we have a use case of appending a list to another one (in
- start_step_over). Based on the std::list and Boost APIs, add a splice
- method. However, only support splicing the other list at the end of the
- `this` list, since that's all we need.
-
- Add explicit default assignment operators to
- reference_to_pointer_iterator, which are otherwise implicitly deleted.
- This is needed because to define thread_step_over_list_safe_iterator, we
- wrap reference_to_pointer_iterator inside a basic_safe_iterator, and
- basic_safe_iterator needs to be able to copy-assign the wrapped
- iterator. The move-assignment operator is therefore not needed, only
- the copy-assignment operator is. But for completeness, add both.

-
- gdb: make inferior_list use intrusive_list
- Change inferior_list, the global list of inferiors, to use
- intrusive_list. I think most other changes are somewhat obvious
- fallouts from this change.
-
- There is a small change in behavior in scoped_mock_context. Before this
- patch, constructing a scoped_mock_context would replace the whole
- inferior list with only the new mock inferior. Tests using two
- scoped_mock_contexts therefore needed to manually link the two inferiors
- together, as the second scoped_mock_context would bump the first mock
- inferior from the thread list. With this patch, a scoped_mock_context
- adds its mock inferior to the inferior list on construction, and removes
- it on destruction. This means that tests run with mock inferiors in the
- inferior list in addition to any pre-existing inferiors (there is always
- at least one). There is no possible pid clash problem, since each
- scoped mock inferior uses its own process target, and pids are per
- process target.

-
- gdb: introduce intrusive_list, make thread_info use it
- GDB currently has several objects that are put in a singly linked list,
- by having the object's type have a "next" pointer directly. For
- example, struct thread_info and struct inferior. Because these are
- simply-linked lists, and we don't keep track of a "tail" pointer, when
- we want to append a new element on the list, we need to walk the whole
- list to find the current tail. It would be nice to get rid of that
- walk. Removing elements from such lists also requires a walk, to find
- the "previous" position relative to the element being removed. To
- eliminate the need for that walk, we could make those lists
- doubly-linked, by adding a "prev" pointer alongside "next". It would be
- nice to avoid the boilerplate associated with maintaining such a list
- manually, though. That is what the new intrusive_list type addresses.
-
- With an intrusive list, it's also possible to move items out of the
- list without destroying them, which is interesting in our case for
- example for threads, when we exit them, but can't destroy them
- immediately. We currently keep exited threads on the thread list, but
- we could change that which would simplify some things.
-
- Note that with std::list, element removal is O(N). I.e., with
- std::list, we need to walk the list to find the iterator pointing to
- the position to remove. However, we could store a list iterator
- inside the object as soon as we put the object in the list, to address
- it, because std::list iterators are not invalidated when other
- elements are added/removed. However, if you need to put the same
- object in more than one list, then std::list<object> doesn't work.
- You need to instead use std::list<object *>, which is less efficient
- for requiring extra memory allocations. For an example of an object
- in multiple lists, see the step_over_next/step_over_prev fields in
- thread_info:
-
- /* Step-over chain. A thread is in the step-over queue if these are
- non-NULL. If only a single thread is in the chain, then these
- fields point to self. */
- struct thread_info *step_over_prev = NULL;
- struct thread_info *step_over_next = NULL;
-
- The new intrusive_list type gives us the advantages of an intrusive
- linked list, while avoiding the boilerplate associated with manually
- maintaining it.
-
- intrusive_list's API follows the standard container interface, and thus
- std::list's interface. It is based the API of Boost's intrusive list,
- here:
-
- https://www.boost.org/doc/libs/1_73_0/doc/html/boost/intrusive/list.html
-
- Our implementation is relatively simple, while Boost's is complicated
- and intertwined due to a lot of customization options, which our version
- doesn't have.
-
- The easiest way to use an intrusive_list is to make the list's element
- type inherit from intrusive_node. This adds a prev/next pointers to
- the element type. However, to support putting the same object in more
- than one list, intrusive_list supports putting the "node" info as a
- field member, so you can have more than one such nodes, one per list.
-
- As a first guinea pig, this patch makes the per-inferior thread list use
- intrusive_list using the base class method.
-
- Unlike Boost's implementation, ours is not a circular list. An earlier
- version of the patch was circular: the intrusive_list type included an
- intrusive_list_node "head". In this design, a node contained pointers
- to the previous and next nodes, not the previous and next elements.
- This wasn't great for when debugging GDB with GDB, as it was difficult
- to get from a pointer to the node to a pointer to the element. With the
- design proposed in this patch, nodes contain pointers to the previous
- and next elements, making it easy to traverse the list by hand and
- inspect each element.
-
- The intrusive_list object contains pointers to the first and last
- elements of the list. They are nullptr if the list is empty.
- Each element's node contains a pointer to the previous and next
- elements. The first element's previous pointer is nullptr and the last
- element's next pointer is nullptr. Therefore, if there's a single
- element in the list, both its previous and next pointers are nullptr.
- To differentiate such an element from an element that is not linked into
- a list, the previous and next pointers contain a special value (-1) when
- the node is not linked. This is necessary to be able to reliably tell
- if a given node is currently linked or not.
-
- A begin() iterator points to the first item in the list. An end()
- iterator contains nullptr. This makes iteration until end naturally
- work, as advancing past the last element will make the iterator contain
- nullptr, making it equal to the end iterator. If the list is empty,
- a begin() iterator will contain nullptr from the start, and therefore be
- immediately equal to the end.
-
- Iterating on an intrusive_list yields references to objects (e.g.
- `thread_info&`). The rest of GDB currently expects iterators and ranges
- to yield pointers (e.g. `thread_info*`). To bridge the gap, add the
- reference_to_pointer_iterator type. It is used to define
- inf_threads_iterator.
-
- Add a Python pretty-printer, to help inspecting intrusive lists when
- debugging GDB with GDB. Here's an example of the output:
-
- (top-gdb) p current_inferior_.m_obj.thread_list
- $1 = intrusive list of thread_info = {0x61700002c000, 0x617000069080, 0x617000069400, 0x61700006d680, 0x61700006eb80}
-
- It's not possible with current master, but with this patch [1] that I
- hope will be merged eventually, it's possible to index the list and
- access the pretty-printed value's children:
-
- (top-gdb) p current_inferior_.m_obj.thread_list[1]
- $2 = (thread_info *) 0x617000069080
- (top-gdb) p current_inferior_.m_obj.thread_list[1].ptid
- $3 = {
- m_pid = 406499,
- m_lwp = 406503,
- m_tid = 0
- }
-
- Even though iterating the list in C++ yields references, the Python
- pretty-printer yields pointers. The reason for this is that the output
- of printing the thread list above would be unreadable, IMO, if each
- thread_info object was printed in-line, since they contain so much
- information. I think it's more useful to print pointers, and let the
- user drill down as needed.

- PR28069, assertion fail in dwarf.c:display_discr_list
- We shouldn't be asserting on anything to do with leb128 values, or

- It would only make sense to assert or report dwarf.c/readelf.c source

- values.
-
- After removing the assertions, the testcase then gave:
-
- <37> DW_AT_discr_list : 5 byte block: 0 0 0 0 0 (label 0, label 0, label 0, label 0, <corrupt>

- gdb: don't set Linux-specific displaced stepping methods in s390_gdbarch_init
- According to bug 28056, running an s390x binary gives:
-
- (gdb) run
- Starting program: /usr/bin/ls
- /home/ubuntu/tmp/gdb-11.0.90.20210705/gdb/linux-tdep.c:2550: internal-error: displaced_step_prepare_status linux_displaced_step_prepare(gdbarch*, thread_info*, CORE_ADDR&): Assertion `gdbarch_data->num_disp_step_buffers > 0' failed.
-
- This is because the s390 architecture registers some Linux-specific
- displaced stepping callbacks in the OS-agnostic s390_gdbarch_init:
-
- set_gdbarch_displaced_step_prepare (gdbarch, linux_displaced_step_prepare);
- set_gdbarch_displaced_step_finish (gdbarch, linux_displaced_step_finish);
- set_gdbarch_displaced_step_restore_all_in_ptid
- (gdbarch, linux_displaced_step_restore_all_in_ptid);
-
- But then the Linux-specific s390_linux_init_abi_any passes
- num_disp_step_buffers=0 to linux_init_abi:
-
- linux_init_abi (info, gdbarch, 0);
-
- The problem happens when linux_displaced_step_prepare is called for the
- first time. It tries to allocate the displaced stepping buffers, but
- sees that the number of displaced stepping buffers for that architecture
- is 0, which is unexpected / invalid.
-
- s390_gdbarch_init should not register the linux_* callbacks, that is
- expected to be done by linux_init_abi. If debugging a bare-metal s390
- program, or an s390 program on another OS GDB doesn't know about, we
- wouldn't want to use them. We would either register no callbacks, if
- displaced stepping isn't supported, or register a different set of
- callbacks if we wanted to support displaced stepping in those cases.
-
- The commit that refactored the displaced stepping machinery and
- introduced these set_gdbarch_displaced_step_* calls is 187b041e2514
- ("gdb: move displaced stepping logic to gdbarch, allow starting
- concurrent displaced steps"). However, even before that,
- s390_gdbarch_init did:
-
- set_gdbarch_displaced_step_location (gdbarch, linux_displaced_step_location);
-
- ... which already seemed wrong. The Linux-specific callback was used
- even for non-Linux system. Maybe that was on purpose, because it would
- also happen to work in some other non-Linux case, or maybe it was simply
- a mistake. I'll assume that this was a small mistake when
- s390-tdep.{h,c} where factored out of s390-linux-tdep.c, in d6e589456475
- ("s390: Split up s390-linux-tdep.c into two files").
-
- Fix this by removing the setting of these displaced step callbacks from
- s390_gdbarch_init. Instead, pass num_disp_step_buffers=1 to
- linux_init_abi, in s390_linux_init_abi_any. Doing so will cause
- linux_init_abi to register these same callbacks. It will also mean that
- when debugging a bare-metal s390 executable or an executable on another
- OS that GDB doesn't know about, gdbarch_displaced_step_prepare won't be
- set, so displaced stepping won't be used.
-
- This patch will need to be merged in the gdb-11-branch, since this is a
- GDB 11 regression, so here's the ChangeLog entry:
-
- gdb/ChangeLog:
-
- * s390-linux-tdep.c (s390_linux_init_abi_any): Pass 1 (number
- of displaced stepping buffers to linux_init_abi.
- * s390-tdep.c (s390_gdbarch_init): Don't set the Linux-specific
- displaced-stepping gdbarch callbacks.

- gdb/Makefile.in: remove testsuite from SUBDIRS
- When distclean-ing a configured / built gdb directory, like so:
-
- $ ./configure && make all-gdb && make distclean
-
- The distclean operation fails with:
-
- Missing testsuite/Makefile
-
- If we look at the SUBDIRS variable in the generated gdb/Makefile,
- testsuite is there twice:
-
- SUBDIRS = doc testsuite data-directory testsuite
-
- So we try distclean-ing the testsuite directory twice. The second time,
- gdb/testsuite/Makefile doesn't exist, so it fails.
-
- The first "testsuite" comes from the @subdirs@ replacement, because of
- the `AC_CONFIG_SUBDIRS` macro in gdb/configure.ac. The second one is
- hard-coded in gdb/Makefile.in:
-
- SUBDIRS = doc @subdirs@ data-directory testsuite
-
- The hard-coded was added by:
-
- bdbbcd577460 ("Always build 'all' in gdb/testsuite")
-
- which came after `testsuite` was removed from @subdirs@ by:
-
- f99d1d37496f ("Remove gdb/testsuite/configure")
-
- My commit a100a94530eb ("gdb/testsuite: restore configure script")
- should have removed the hard-coded `testsuite`, since it added it back
- as a "subdir", but I missed it because I only looked f99d1d37496f to
- write my patch.
-
- Fix this by removing the hard-coded one.
-
- This patch should be pushed to both master and gdb-11-branch, hence the
- ChangeLog entry:
-
- gdb/ChangeLog:
-
- * Makefile.in (SUBDIRS): Remove testsuite.

- gdb: introduce iterator_range, remove next_adapter
- I was always a bit confused by next_adapter, because it kind of mixes
- the element type and the iterator type. In reality, it is not much more
- than a class that wraps two iterators (begin and end). However, it
- assumes that:
-
- - you can construct the begin iterator by passing a pointer to the
- first element of the iterable
- - you can default-construct iterator to make the end iterator
-
- I think that by generalizing it a little bit, we can re-use it at more
- places.
-
- Rename it to "iterator_range". I think it describes a bit better: it's
- a range made by wrapping a begin and end iterator. Move it to its own
- file, since it's not related to next_iterator anymore.
-
- iterator_range has two constructors. The variadic one, where arguments
- are forwarded to construct the underlying begin iterator. The end
- iterator is constructed through default construction. This is a
- generalization of what we have today.
-
- There is another constructor which receives already constructed begin
- and end iterators, useful if the end iterator can't be obtained by
- default-construction. Or, if you wanted to make a range that does not
- end at the end of the container, you could pass any iterator as the
- "end".
-
- This generalization allows removing some "range" classes, like
- all_inferiors_range. These classes existed only to pass some arguments
- when constructing the begin iterator. With iterator_range, those same
- arguments are passed to the iterator_range constructed and then
- forwarded to the constructed begin iterator.
-
- There is a small functional difference in how iterator_range works
- compared to next_adapter. next_adapter stored the pointer it received
- as argument and constructeur an iterator in the `begin` method.
- iterator_range constructs the begin iterator and stores it as a member.
- Its `begin` method returns a copy of that iterator.
-
- With just iterator_range, uses of next_adapter<foo> would be replaced
- with:

- gdb/testsuite: restore configure script
- Commit f99d1d37496f ("Remove gdb/testsuite/configure") removed
- gdb/testsuite/configure, as anything gdb/testsuite/configure did could
- be done by gdb/configure.
-
- There is however one use case that popped up when this changed
- propagated to downstream consumers, to run the testsuite on an already
- built GDB. In the workflow of ROCm-GDB at AMD, a GDB package is built
- in a CI job. This GDB package is then tested on different machines /
- hardware configurations as part of other CI jobs. To achieve this,
- those CI jobs only configure the testsuite directory and run "make
- check" with an appropriate board file.
-
- In light of this use case, the way I see it is that gdb/testsuite could
- be considered its own project. It could be stored in a completely
- different repo if we want to, it just happens to be stored inside gdb/.
-
- Since the only downside of having gdb/testsuite/configure is that it
- takes a few more seconds to run, but on the other hand it's quite useful
- for some people, I propose re-adding it.
-
- In a sense, this is revert of f99d1d37496f, but it's not a direct
- git-revert, as some things have changed since.
-
- gdb/ChangeLog:
-
- * configure.ac: Remove things that were moved from
- testsuite/configure.ac.
- * configure: Re-generate.
-
- gdb/testsuite/ChangeLog:
-
- * configure.ac: Restore.
- * configure: Re-generate.
- * aclocal.m4: Re-generate.

- Update gdb performance testsuite to be compatible with Python 3.8
- Running "make check-perf" on a system with Python 3.8 (e.g., Ubuntu
- 20.04) runs into this Python problem:
-
- Traceback (most recent call last):
- File "<string>", line 1, in <module>
- File "/home/pedro/rocm/gdb/src/gdb/testsuite/gdb.perf/lib/perftest/perftest.py", line 65, in run
- self.execute_test()
- File "<string>", line 35, in execute_test
- File "/home/pedro/rocm/gdb/src/gdb/testsuite/gdb.perf/lib/perftest/measure.py", line 45, in measure
- m.start(id)
- File "/home/pedro/rocm/gdb/src/gdb/testsuite/gdb.perf/lib/perftest/measure.py", line 102, in start
- self.start_time = time.clock()
- AttributeError: module 'time' has no attribute 'clock'
- Error while executing Python code.
- (gdb) FAIL: gdb.perf/single-step.exp: python SingleStep(1000).run()
-
- ... many times over.
-
- The problem is that the testsuite is using time.clock(), deprecated in
- Python 3.3 and finaly removed in Python 3.8. The guidelines say to
- use time.perf_counter() or time.process_time() instead depending on
- requirements. Looking at the current description of those functions,
- at:
-
- https://docs.python.org/3.10/library/time.html
-
- we have:
-
- time.perf_counter() -> float
-
- Return the value (in fractional seconds) of a performance
- counter, i.e. a clock with the highest available resolution to
- measure a short duration. It does include time elapsed during
- sleep and is system-wide. (...)
-
- time.process_time() -> float
-
- Return the value (in fractional seconds) of the sum of the
- system and user CPU time of the current process. It does not
- include time elapsed during sleep. It is process-wide by
- definition. (...)
-
- I'm thinking that it's just best to record both instead of picking
- one. So this patch replaces the MeasurementCpuTime measurement class
- with two new classes -- MeasurementPerfCounter and
- MeasurementProcessTime. Correspondingly, this changes the reports in
- testsuite/perftest.log -- we have two new "perf_counter" and
- "process_time" measurements and the "cpu_time" measurement is gone. I
- don't suppose breaking backward compatibility here is a big problem.
- I suspect no one is really tracking long term performance using the
- perf testsuite today. And if they are, it shouldn't be hard to adjust.
-
- For backward compatility, with Python < 3.3, both perf_counter and
- process_time use the old time.clock.
-
- gdb/testsuite/ChangeLog:
- yyyy-mm-dd Qingchuan Shi <qingchuan.shi@amd.com>

- gdb.perf/: FAIL on Python errors, avoid "ERROR: internal buffer is full"
- Currently, if you run make check-perf on a system with Python 3.8,
- tests seen to PASS, but they actually test a lot less than intended,
- due to:
-
- PerfTest::assemble, run ...
- python BackTrace(64).run()
- Traceback (most recent call last):
- File "<string>", line 1, in <module>
- File "/home/pedro/rocm/gdb/src/gdb/testsuite/gdb.perf/lib/perftest/perftest.py", line 65, in run

- Error while executing Python code.
- (gdb) PASS: gdb.perf/backtrace.exp: python BackTrace(64).run()

- [gdb/testsuite] Remove read1 timeout factor from gdb.base/info-macros.exp
- At the moment some check-read1 timeouts are handled like this in
- gdb.base/info-macros.exp:
- ...
- gdb_test_multiple_with_read1_timeout_factor 10 "$test" $testname {
- -re "$r1$r2$r3" {
- pass $testname
- }
- -re ".*#define TWO.*\r\n$gdb_prompt" {
- fail $testname
- }
- -re ".*#define THREE.*\r\n$gdb_prompt" {
- fail $testname
- }
- -re ".*#define FOUR.*\r\n$gdb_prompt" {
- fail $testname
- }
- }
- ...
- which is not ideal.
-
- We could use gdb_test_lines, but it currently doesn't support verifying
- the absence of regexps, which is done using the clauses above calling fail.
-
- Fix this by using gdb_test_lines and adding a -re-not syntax to
- gdb_test_lines, such that we can do:
- ...
- gdb_test_lines $test $testname $r1.*$r2 \
- -re-not "#define TWO" \
- -re-not "#define THREE" \
- -re-not "#define FOUR"
- ...
-
- Tested on x86_64-linux, whith make targets check and check-read1.

- [gdb/symtab] Fix skipping of import of C++ CU
- Tom Tromey observed that when changing the language in

- ...
- /* We're importing a C++ compilation unit with tag DW_TAG_compile_unit
- into another compilation unit, at root level. Regard this as a hint,
- and ignore it. */
- if (die->parent && die->parent->parent == NULL

- - "type = void \\(character\\*\\(\\*\\), integer\\(kind=\\d+\\)\\)"
- + "type = void \\(character\[^,\]+, $integer8\\)"

- which fails to take into account that for gcc-7 and before, the type for
- string length of a string argument is int, not size_t.

- The macOS platform does not provide sigtimedwait, so we get:

- sigtimedwait (&set, nullptr, &zero_timeout);
- ^
-
- An alternative to sigtimedwait with a timeout of 0 is to use sigpending,
- to first check which signals are pending, and then sigwait, to consume
- them. Since that's slightly more expensive (2 syscalls instead of 1),
- keep using sigtimedwait for the platforms that provide it, and fall back
- to sigpending + sigwait for the others.

- PR28055, segfault in bpf special reloc function
- The testcase in this PR tickled two bugs fixed here. output_bfd is
- NULL when a reloc special_function is called for final linking and
- when called from bfd_generic_get_relocated_section_contents. Clearly
- using output_bfd is wrong as it results in segfaults. Not only that,
- the endianness of the reloc field really should be that of the input.
- The second bug was not checking that the entire reloc field was
- contained in the section contents.
-
- PR 28055
- * elf64-bpf.c (bpf_elf_generic_reloc): Use correct bfd for bfd_put
- and bfd_put_32 calls. Correct section limit checks.

-
- PR 28047
- * dwarf.c (get_type_abbrev_from_form): Add cu_end parameter.
- Check DW_FORM_ref1 etc. arg against cu_end rather than end of
- section. Adjust all callers.

- gdb: return early if no execution in darwin_solib_create_inferior_hook
- When loading a file using the file command on macOS, we get:
-
- $ ./gdb -nx --data-directory=data-directory -q -ex "file ./test"
- Reading symbols from ./test...

- A problem internal to GDB has been detected,
- further debugging may prove unreliable.
- Quit this debugging session? (y or n)

- The solib_create_inferior_hook call in symbol_file_command was added by
- commit ea142fbfc9c1 ("Fix breakpoints on file reloads for PIE
- binaries"). It causes solib_create_inferior_hook to be called while
- the inferior is not running, which darwin_solib_create_inferior_hook
- does not expect. darwin_solib_get_all_image_info_addr_at_init, in
- particular, assumes that there is a current thread, as it tries to get
- the current thread's regcache.
-
- Fix it by adding a target_has_execution check and returning early. Note
- that there is a similar check in svr4_solib_create_inferior_hook.
-
- gdb/ChangeLog:
-
- * solib-darwin.c (darwin_solib_create_inferior_hook): Return
- early if no execution.
