* New file.
* (EXTRA_DIST): Add it.
(make-debug-archive): New target.
2007-10-10 Roland McGrath <>
* elflint.c (special_sections): Add new attrflag value exact_or_gnuld.
Use it to check MERGE|STRINGS for .debug_str.
(check_sections): Handle exact_or_gnuld.
2007-10-08 Roland McGrath <>
* readelf.c (handle_core_item): Handle 'T'|0x80 to indicate
64-bit struct timeval with 32-bit tv_usec.
2007-10-07 Roland McGrath <>
* readelf.c (check_archive_index): New function.
(process_file): Call it. Change signature to take only fd and name.
Use libdwfl to open the file, then iterate on its modules (multiple
for an archive) to print file name and call process_elf_file.
(main): Update caller. Let process_file do elf_begin.
(count_dwflmod, process_dwflmod, find_no_debuginfo): New functions.
(process_elf_file): Take only Dwfl_Module * argument.
Don't print the file name here.
(print_debug_*_section): Take Dwfl_Module * argument.
(print_debug): Likewise. Update caller.
(format_dwarf_addr): New function.
(print_debug_ranges_section): Use it.
(attr_callback): Likewise.
(print_debug_line_section, print_debug_loc_section): Likewise.
* readelf.c (print_debug_ranges_section): Translate all strings.
(print_debug_loc_section): Likewise.
* unstrip.c (copy_elided_sections): Initialize SEC.
* ar.c (do_oper_insert): Put trailing / on short names.
* arlib.h (MAX_AR_NAME_LEN): Decrease by one.
* arlib2.c (arlib_add_long_name): Adjust for header size.
* arlib.c (arlib_finalize): Pad long name table to keep size even.
* ar.c (do_oper_insert): Use write_retry for padding write.
* ar.c (do_oper_insert): Initialize CUR_OFF in no_old case.
Unconditionally set FOUND[CNT]->elf when setting ->mem.
(remember_long_name): New function.
(do_oper_insert): Call it. Correctly use length of basename,
not original name. Don't store long name twice for new member.
2007-10-06 Roland McGrath <>
* elflint.c (check_note): Skip empty segment.
(check_note_section): Skip empty section.
* unstrip.c (options, parse_opt, struct arg_info): Grok -R/--relocate.
(handle_output_dir_module, handle_implicit_modules): Pass it down.
(handle_dwfl_module): When set, use ET_REL already loaded by Dwfl.
(compare_alloc_sections): Take new arg REL, ignore address if true.
(compare_sections): Likewise, pass it down.
(compare_sections_rel, compare_sections_nonrel): New functions.
(find_alloc_sections_prelink, copy_elided_sections): Use them
instead of compare_sections.
(sections_match): New function, broken out of ...
(find_alloc_section): ... here.
(copy_elided_sections): Reorganize section match-up logic.
Use sections_match for SHF_ALLOC in ET_REL.
For ET_REL, let the nonzero sh_addr from the debug file dominate.
* unstrip.c (add_new_section_symbols): Take new arg REL.
When true, do not update section symbol values.
(collect_symbols): Likewise. Update section symbols with address
of chosen output section, not original section.
(check_symtab_section_symbols, copy_elided_sections): Update callers.
* unstrip.c (compare_alloc_sections): At the same address, preserve
original section order.
* elflint.c (special_sections): Don't require MERGE|STRINGS for
.debug_str, it didn't always have them with older tools.
* elflint.c (check_symtab, check_one_reloc): Ignore sh_addr in ET_REL.
2007-10-05 Roland McGrath <>
* elflint.c (check_symtab): Allow SHN_UNDEF _GLOBAL_OFFSET_TABLE_ in
ET_REL file.
* elflint.c (check_symtab): For _GLOBAL_OFFSET_TABLE_, diagnose
SHN_UNDEF as "bad section". Use shndx value in messages.
* elflint.c (special_sections): Add ".debug_str". Decrement namelen
for ".debug" so it matches as a prefix.
(IS_KNOWN_SPECIAL): New macro.
(check_sections): Use it for ".plt" match. Cite wrong SHT_NOBITS
type even under -d, for a .debug* or .shstrtab section.
* readelf.c (print_ops): Use hex for address operand.
2007-10-04 Roland McGrath <>
* unstrip.c (copy_elided_sections): Initialize NDX_SECTION element for
.gnu_debuglink section to SHN_UNDEF. Drop STT_SECTION symbols for
sections mapped to SHN_UNDEF.
2007-10-04 Ulrich Drepper <>
* readelf.c (dump_archive_index): Avoid warning about uninitialized
variable with older glibc versions.
Add some branch prediction.
2007-10-04 Roland McGrath <>
* readelf.c (print_archive_index): New variable.
(options, parse_opt): Accept -c/--archive-index to set it.
(dump_archive_index): New function.
(process_file): Take new arg WILL_PRINT_ARCHIVE_INDEX.
Call dump_archive_index on archives if set.
(main): Update caller.
(any_control_option): Give it file scope, moved out of ...
(parse_opt): ... here.
