  20 2021-02-21  Alan Modra  <amodra@gmail.com>
  21
  22         * configure.ac: Invoke AC_CANONICAL_TARGET, AC_CANONICAL_HOST
  23         and AC_CANONICAL_BUILD.
  24         * configure: Regenerate.

  26
  27 2021-02-20  Nick Alcock  <nick.alcock@oracle.com>
  28
  29         * ctf-impl.h (ctf_dict_t) <ctf_symhash>: New.
  30         <ctf_symhash_latest>: Likewise.
  31         (struct ctf_archive_internal) <ctfi_crossdict_cache>: New.
  32         <ctfi_symnamedicts>: New.
  33         <ctfi_syms>: Remove.
  34         (ctf_lookup_symbol_name): Remove.
  35         * ctf-lookup.c (ctf_lookup_symbol_name): Propagate errors from
  36         parent properly.  Make static.
  37         (ctf_lookup_symbol_idx): New, linear search for the symbol name,
  38         cached in the crossdict cache's ctf_symhash (if available), or
  39         this dict's (otherwise).
  40         (ctf_try_lookup_indexed): Allow the symname to be passed in.
  41         (ctf_lookup_by_symbol): Turn into a wrapper around...
  42         (ctf_lookup_by_sym_or_name): ... this, supporting name lookup too,
  43         using ctf_lookup_symbol_idx in non-writable dicts.  Special-case
  44         name lookup in dynamic dicts without reported symbols, which have
  45         no symtab or dynsymidx but where name lookup should still work.
  46         (ctf_lookup_by_symbol_name): New, another wrapper.
  47         * ctf-archive.c (enosym): Note that this is present in
  48         ctfi_symnamedicts too.
  49         (ctf_arc_close): Adjust for removal of ctfi_syms.  Free the
  50         ctfi_symnamedicts.
  51         (ctf_arc_flush_caches): Likewise.
  52         (ctf_dict_open_cached): Memoize the first cached dict in the
  53         crossdict cache.
  54         (ctf_arc_lookup_symbol): Turn into a wrapper around...
  55         (ctf_arc_lookup_sym_or_name): ... this.  No longer cache
  56         ctf_id_t lookups: just call ctf_lookup_by_symbol as needed (but
  57         still cache the dicts those lookups succeed in).  Add
  58         lookup-by-name support, with dicts of successful lookups cached in
  59         ctfi_symnamedicts.  Refactor the caching code a bit.
  60         (ctf_arc_lookup_symbol_name): New, another wrapper.
  61         * ctf-open.c (ctf_dict_close): Free the ctf_symhash.
  62         * libctf.ver (LIBCTF_1.2): New version.  Add
  63         ctf_lookup_by_symbol_name, ctf_arc_lookup_symbol_name.
  64         * testsuite/libctf-lookup/enum-symbol.c (main): Use
  65         ctf_arc_lookup_symbol rather than looking up the name ourselves.
  66         Fish it out repeatedly, to make sure that symbol caching isn't
  67         broken.
  68         (symidx_64): Remove.
  69         (symidx_32): Remove.
  70         * testsuite/libctf-lookup/enum-symbol-obj.lk: Test symbol lookup
  71         in an unlinked object file (indexed symtypetab sections only).
  72         * testsuite/libctf-writable/symtypetab-nonlinker-writeout.c
  73         (try_maybe_reporting): Check symbol types via
  74         ctf_lookup_by_symbol_name as well as ctf_symbol_next.
  75         * testsuite/libctf-lookup/conflicting-type-syms.*: New test of
  76         lookups in a multi-dict archive.

  90
  91 2021-02-03  Nick Alcock  <nick.alcock@oracle.com>
  92
  93         * configure.ac (EXPECT): Check for, in order to define...
  94         (TCL_TRY): ... this, if Tcl supports try/catch.
  95         * Makefile.am (TCL_TRY): Run the testsuite only if set.
  96         * configure: Regenerated.
  97         * Makefile.in: Likewise.

 151         final link).
 152         (ctf_serialize): Handle the !LCTF_LINKING case by writing out an
 153         indexed, sorted symtypetab (and allow SYMFP to be NULL in this
 154         case).  Turn sorting off if this is a non-final link.  Only delete
 155         nonstatic vars if we are filtering symbols and the linker has
 156         reported some.
 157         * testsuite/libctf-regression/nonstatic-var-section-ld-r*:
 158         New test of variable and symtypetab section population when
 159         ld -r is used.
 160         * testsuite/libctf-regression/nonstatic-var-section-ld-executable.lk:
 161         Likewise, when ld of an executable is used.

 163         Likewise, when ld -shared alone is used.
 164         * testsuite/libctf-regression/nonstatic-var-section-ld*.c:
 165         Lookup programs for the above.
 166         * testsuite/libctf-writable/symtypetab-nonlinker-writeout.*: New
 167         test, testing survival of symbols across ctf_write paths.
 168         * testsuite/lib/ctf-lib.exp (run_lookup_test): New option,
 169         nonshared, suppressing linking of the SOURCE with -shared.

 336         * ctf-dump.c (ctf_dump_membstate_t) <cdm_toplevel_indent>: Constify.
 337         (CTF_FT_REFS): New.
 338         (CTF_FT_BITFIELD): Likewise.
 339         (CTF_FT_ID): Likewise.
 340         (ctf_dump_member): Do not do indentation here. Migrate the
 341         type-printing parts of this into...
 342         (ctf_dump_format_type): ... here, to be shared by all type printers.
 343         Get the errno value for non-representable types right.  Do not print
 344         bitfield info for non-bitfields.  Improve the format and indentation
 345         of other type output.  Shuffle spacing around to make all indentation
 346         either 'width of column' or 4 chars.
 347         (ctf_dump_label): Pass CTF_FT_REFS to ctf_dump_format_type.
 348         (ctf_dump_objts): Likewise.  Spacing shuffle.
 349         (ctf_dump_var): Likewise.
 350         (type_hex_digits): Migrate down in the file, to above its new user.
 351         (ctf_dump_type): Indent here instead.  Pass CTF_FT_REFS to
 352         ctf_dump_format_type. Don't trim off excess linefeeds now we no
 353         longer generate them.  Dump enumerated types.

 357         * ctf-types.c (ctf_type_resolve): Improve comment.
 358         (ctf_type_size): Yield ECTF_INCOMPLETE when applied to forwards.
 359         Emit errors into the right dict.
 360         (ctf_type_align): Likewise.
 361         * ctf-create.c (ctf_add_member_offset): Yield ECTF_INCOMPLETE
 362         when adding a member without explicit offset when this member, or
 363         the previous member, is incomplete.
 364         * ctf-dump.c (ctf_dump_format_type): Do not try to print the size of
 365         forwards.
 366         (ctf_dump_member): Do not try to print their alignment.

 371         (ctf_dump_format_type): Don't emit the size for function objects.
 372         Dump the element type of arrays like we dump the pointed-to type of
 373         pointers, etc.

 379         (ctf_dump_str): Add 0x to the hex string offsets.
 380         (ctf_dump_membstate_t) <cdm_toplevel_indent>: New.
 381         (ctf_dump_type): Adjust.  Free it when we're done.
 382         (type_hex_digits): New.
 383         (ctf_dump_member): Align output depending on the width of the type
 384         ID being generated.  Use printf padding, not a loop, to generate
 385         indentation.
