2022-07-09Regenerate with automake-1.15.1Alan Modra3-482/+304
Until we update the recommended versions of autoconf/automake, files should be regenerated with automake-1.15.1 and autoconf-2.69. That's not because we think those versions are golden, and newer versions are bad. It's simply because maintainers want to be able to update configury files without trouble, and if someone regenerates files with automake-1.16.5 then --enable-maintainer-mode builds will hit errors: checking that generated files are newer than configure... configure.ac:26: error: version mismatch. This is Automake 1.15.1, configure.ac:26: but the definition used by this AM_INIT_AUTOMAKE 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. Correcting this requires regenerating the files by hand.

2022-07-06Descriptive DWARF operations dump support for DW_AT_rankBhuvanendra Kumar N1-0/+1
DW_AT_rank is a dwarf-5 feature.
2022-07-05Support for location and range lists for split-dwarf and dwarf-5.Bhuvanendra Kumar N2-9/+34
Adding support for location and range lists for split-dwarf and dwarf-5. Following issues are taken care. 1. Display of the index values for DW_FORM_loclistx and DW_FORM_rnglistx. 2. Display of .debug_loclists.dwo and .debug_rnglists.dwo sections. * dwarf.c(read_and_display_attr_value): Handle DW_FORM_loclistx and DW_FORM_rnglistx for .dwo files. (process_debug_info): Load .debug_loclists.dwo and .debug_rnglists.dwo if exists. (load_separate_debug_files): Load .debug_loclists and .debug_rnglists if exists. Include 2 entries in debug_displays table. * dwarf.h (enum dwarf_section_display_enum): Include 2 entries.
2022-07-04objcopy: bfd_alloc orelocationAlan Modra3-24/+28
This fixes an inconsequential objcopy memory leak. I'd normally ignore reports of leaks like this one, that are merely one block or fewer per section processed, since objcopy soon exits and frees all memory. However I thought it worth providing support for allocating memory on a bfd objalloc in objcopy and other utils. PR 29233 * bucomm.c (bfd_xalloc): New function. * bucomm.h (bfd_xalloc): Declare. * objcopy.c (copy_relocations_in_section): Use it to allocate array of reloc pointers. Rewrite code stripping relocs to do without extra memory allocation.

2022-06-27drop XC16x bitsJan Beulich1-14/+0
Commit 04f096fb9e25 ("Move the xc16x target to the obsolete list") moved the architecture from the "obsolete but still available" to the "obsolete / support removed" list in config.bfd, making the architecture impossible to enable (except maybe via "enable everything" options"). Note that I didn't touch */po/*.po{,t} on the assumption that these would be updated by some (half)automatic means.
2022-06-27Fix location list offset address dump under DW_AT_location (dwarf-5)Bhuvanendra Kumar N1-12/+26
For clang compiled objects with dwarf-5, location list offset address dump under DW_AT_location is corrected, where DW_FORM_loclistx is used. While dumping the location list offset, the address dumped is wrong where it was refering to .debug_addr instead of .debug_loclists * dwarf.c (fetch_indexed_value): Add base_address as parameter and use it to access the section offset. (read_and_display_attr_value): Handle DW_FORM_loclistx form separately. Pass loclists_base to fetch_indexed_value().

2022-06-22readelf: replace xmalloc with malloc in slurp_relr_relocsMarcus Nilsson2-1/+6

2022-05-31Trailing spaces in objdump -r headerAlan Modra1-1/+1
git commit 202be274a4 went a little wild in removing trailing spaces in gas/testsuite/gas/i386/{secidx.d,secrel.d}, causing x86_64-w64-mingw32 +FAIL: i386 secrel reloc x86_64-w64-mingw32 +FAIL: i386 secidx reloc I could have just replaced the trailing space, but let's fix the objdump output instead.

2022-05-27Remove use of bfd_uint64_t and similarAlan Modra4-124/+35
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.
