The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.
The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.
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 99ad839030
Here, bfd_coff_aoutsz must match coff_swap_aouthdr_out otherwise we
end up writing garbage.
/* Note that peicode.h fills in a PEAOUTHDR, not an AOUTHDR.
include/coff/pe.h sets AOUTSZ == sizeof (PEAOUTHDR)). */
char * buff;
bfd_size_type amount = bfd_coff_aoutsz (abfd);
buff = (char *) bfd_malloc (amount);
if (buff == NULL)
return false;
coff_swap_aouthdr_out (abfd, & internal_a, buff);
amount = bfd_bwrite (buff, amount, abfd);
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.

When linking Windows x86-64 relocatable object files to generate x86-64
ELF executable, we need to subtract __ImageBase, aka __executable_start,
for R_AMD64_IMAGEBASE relocation:
1. Add link_info to struct output_elf_obj_tdata to store linker info and
_bfd_get_link_info() to retrieve it.
2. Add ldelf_set_output_arch to set up link_info.
3. Add pex64_link_add_symbols to create an indirect reference to
__executable_start for __ImageBase to support R_AMD64_IMAGEBASE relocation
when adding symbols from Windows x86-64 relocatable object files to
generate x86-64 ELF executable.
4. Also subtract __ImageBase for R_AMD64_IMAGEBASE when generating x86-64
ELF executable.

The 64-bit version of binutils got support for the PE COFF BIG OBJ format a
couple of years ago. The BIG OBJ format is a slightly different COFF format
which extends the size of the number of section field in the header from a
uint16_t to a uint32_t and so greatly increases the number of sections allowed.
However the 32-bit version of bfd never got support for this. The GHC Haskell
compiler generates a great deal of symbols due to it's use of
-ffunction-sections and -fdata-sections.
This meant that we could not build the 32-bit version of the GHC Compiler for
many releases now as binutils didn't have this support.
This patch adds the support to the 32-bit port of binutils as well and also does
come cleanup in the code.
