gdb: fix slowdown during skeletonless type units processing
My commit 6474c699a525 ("gdb/dwarf: sort dwarf2_per_bfd::all_units by
(section, offset)") introduced a pretty bad performance regression in
the "skeletonless type units" step. I have a pretty big executable
(Blender) compiled with -gsplit-dwarf (to generate .dwo files) and
-fdebug-types-section (to generate type units). Before the offending
commit:
Time for "DWARF skeletonless type units": wall 29.126, user 28.507, sys 0.497, user+sys 29.004, 99.6 % CPU
... and after:
Time for "DWARF skeletonless type units": wall 120.768, user 119.543, sys 0.651, user+sys 120.194, 99.5 % CPU
The reason for the slowdown is that add_type_unit now inserts type units
at the right place in the all_units vector to keep it sorted. These
repeated insertions in the middle of the vector require shifting a lot
of elements and end up taking a lot of time.
This patch fixes it by doing just one sort at the end of
process_skeletonless_type_units. The responsibility of keeping the
all_units sorted is delegated to the callers of add_type_unit. The
other two callers call finalize_all_units right after calling
add_type_unit.
One drawback that is probably not a real one: in
process_skeletonless_type_unit, we call process_type_unit. If something
in there needs to look up another type unit by (section, offset), it
wouldn't find it. I don't think that's a real issue though, as type
units are typically self contained. If a type unit needs to refer to a
type defined in another type unit, it would do so by signature, with
DW_FORM_ref_sig8. And during the indexing phase, I don't think we even
look at the DW_AT_type of things anyway.
With this patch applied, I am back to:
Time for "DWARF skeletonless type units": wall 29.277, user 28.632, sys 0.521, user+sys 29.153, 99.6 % CPU
I would like to cherry pick this patch to GDB 17, to avoid shipping GDB
17 with the performance regression.

[gdb/tdep] Fix inferior call return of small char array for ppc64 v1 abi some more
PR tdep/33534 reports a regression due to commit 13f1820106c ("[gdb/tdep] Fix
inferior call return of small char array for ppc64 v1 abi").
The regression can be reproduced with the test-case introduced in the commit:
gdb.ada/return-small-char-array.exp, on a ppc64-linux setup with v1 elf abi
(cfarm121).
The commit contains two changes to a piece of code in
ppc64_sysv_abi_return_value:
...
/* Small character arrays are returned, right justified, in r3. */
- if (valtype->code () == TYPE_CODE_ARRAY
+ if (tdep->elf_abi == POWERPC_ELF_V1
+ && valtype->code () == TYPE_CODE_ARRAY
&& !valtype->is_vector ()
&& valtype->length () <= 8
- && valtype->target_type ()->code () == TYPE_CODE_INT
+ && (valtype->target_type ()->code () == TYPE_CODE_INT
+ || valtype->target_type ()->code () == TYPE_CODE_CHAR)
&& valtype->target_type ()->length () == 1)
...
The first change limits the effect of the if clause to the v1 elf abi. This
change doesn't affect the regression, since it's on a ppc64-linux setup with
v1 elf abi. Furthermore, it's correct in the sense that the v2 elf abi
doesn't have this kind of special treatment of small character arrays.
The second change is the part that causes the regression. The code itself
seems correct, in the sense that it enables gdb to recognize small char arrays
in ada.
The regression stems from the following discrepancy.
The comment in gdb states that "small character arrays are returned, right
justified, in r3". This matches the v1 ABI [1].
OTOH, gcc produces code that is not in agreement with this. Instead, it
passes the small character arrays in memory, in a caller-allocated storage
buffer pointed at by r3. This turns out to be an gcc bug [2].
Fix this by treating this as an abi spec bug, and replacing the code handling
the "Small character arrays" case with a comment.
Doing so reveals that there are two problems in the test-case:
- missing fvar-tracking, and
- the "step 2" command doesn't land at the intended line.
Fix these by:
- adding fvar-tracking, and
- setting a breakpoint at the intended line, and continuing to it.
Tested on ppc64-linux (v1 abi), ppc64le-linux (v2 abi), and x86_64-linux.

have a hang instead:
...

...
Valgrind complains about an uninitialized field
demangle_component::d_counting, which is fixed by using
cplus_demangle_fill_name in replace_typedefs_qualified_name.
After fixing that, the hang is also reproducible at -O0.
The hang happens because we're stuck in the while loop in
replace_typedefs_qualified_name, replacing "std::string::size_type" with
"std::string::size_type".
Fix this in inspect_type by checking for this situation, getting us instead:

The test-case is a bit unusual:
- pretty-print.cc is a preprocessed c++ source, reduced using cvise [1], then
hand-edited to fix warnings with gcc and clang.
- the pretty-printer .py file is a reduced version of
/usr/share/gcc-15/python/libstdcxx/v6/printers.py.
Using the test-case (and the cplus_demangle_fill_name fix), I managed to
reproduce the hang on both:
- openSUSE Leap 15.6 with gcc 7, and
- openSUSE Tumbleweed with gcc 15.
The test-case compiles with clang, but the hang didn't reproduce.

New '--binary-output' command line option, fix gdb.mi/ testing on Windows
MI testcases currently all fail on native Windows with:
Running /c/gdb/src/gdb/testsuite/gdb.mi/mi-simplerun.exp ...
ERROR: (timeout) GDB never initialized after 10 seconds.
This is because when GDB is started in MI mode, it prints info to the
terminal before -iex options are processed. I.e., before the "maint
set console-translation-mode binary" command in

\r\r\n, like can be easily seen by passing --debug to runtest:

Fix this by adding a new Windows-only --binary-output command line

the testsuite pass that instead of "maint set console-translation-mode
binary".
Remove "maint set console-translation-mode" completely, since the only
reason it existed was for the testsuite, and it was never included in
any release.

In the original GAS bug, the first directory table entry did not contain
the current directory of the compilation. So the above commit added a
workaround fix to prepend the second directory table entry.
However recent Go toolchain compilations (specifically on aarch64)
only output a single directory table entry. Looking at the workaround:
if (lh->version == 5 && lh->is_valid_file_index (1))
{
std::string dir = lh->include_dir_at (1);
fnd.set_comp_dir (std::move (dir));
}
`lh->is_valid_file_index (1)' is true, but since the directory table only
has one entry, `include_dir_at (1)' returns nullptr. Consequently the
std::string ctor will segfault. Since there are no guarantees that the file
and directory tables are the same size, a better bounds check is to simply
rely on `include_dir_at' to ensure a valid directory table entry.
I have updated the workaround commit's test, gdb.dwarf2/dw2-gas-workaround.exp
and tested on x86_64 and aarch64 RHEL 9 and Fedora 41.
GDB: aarch64: Use GCS features to calculate hash of struct aarch64_features
Luis noticed that when adding the gcs and gcs_linux members to struct
aarch64_features in my Guarded Control Stack patch series, I neglected to
modify struct hash<aarch64_features>::operator() to take them into account
when computing its hash.
This can cause GDB to use the wrong aarch64_features object during a
debugging session.
Regression tested on aarch64-linux-gnu.

gdb: Add i386-gnu-tdep to the list of objects for x86_64-*-gnu*
When starting GDB on Hurd amd64, one will currently see the following
warning:
# gdb -q
gdb: warning: A handler for the OS ABI "GNU/Hurd" is not built into this configuration
of GDB. Attempting to continue with the default i386 settings.
(gdb)
This happens because, in gdb/configure.tgt, the "x86_64-*-gnu*" target
is not pulling in the i386-gnu-tdep.o object, which means that only
64-bit debugging is currently supported.
The fix here is to add i386-gnu-tdep.o to the gdb_target_obs for Hurd
amd64.

gdb: Add svr4-tls-tdep.o to list of objects of i*86 targets
GDB currently fails to build from source on i386 if compiled with
--enable-64-bit-bfd. This is happening because svr4-tls-tdep.o is
missing from the gdb_target_obs variable, while amd64-linux-tdep.o is
obviously there.
Fix the problem by adding svr4-tls-tdep.o to the object list, but only
when --enable-64-bit-bfd is provided.

gdb, amd64: extend the amd64 prologue analyzer to skip register pushes
A gdb_test_multiple exits early when processing the results of a
'disassemble' command, without waiting for the prompt to be seen.
This can leave unhandled output in expect's input buffer, which will
then throw off the next test.
Update the gdb_test_multiple to wait for the prompt before declaring
the test passed.
After this I'm no longer seeing the above failure.
There should be no change in what is tested after this commit.
