Adds two new external authors to etc/update-copyright.py to cover
bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then
updates copyright messages as follows:
1) Update cgen/utils.scm emitted copyrights.
2) Run "etc/update-copyright.py --this-year" with an extra external
author I haven't committed, 'Kalray SA.', to cover gas testsuite
files (which should have their copyright message removed).
3) Build with --enable-maintainer-mode --enable-cgen-maint=yes.
4) Check out */po/*.pot which we don't update frequently.
While documented to not be reliable, it is still odd for objcopy to
silently produce bad output when converting COFF/PE object files to ELF
ones. The issue there is that relocation addends all are screwed up by
subtracting the symbol's section offset. In the COFF/PE world, to my
knowledge, section contents stores the addends alone, not the result of
symbol value plus addend. Hence the compensation talked about in a
comment ahead of the sole use site of CALC_ADDEND() may need to account
for the VMA (which is always zero for object files anyway), but not for
the symbol value.
The coff-sh.c adjustment is based upon guessing that behavior there is
the same. Note also how coff-aarch64.c short-circuits CALC_ADDEND()
altogether, which may suggest that a much simpler macro might do for the
COFF_WITH_PE case in the three arch-specific files touched here.
For (at least) Arm/WinCE this actually results in more appropriate
objdump output as well, as can be seen in the one testcase which has its
expectations adjusted (the generated binary doesn't change).
I noticed a few files double-included libcoff.h, and digging deeper I
found that the PEI_HEADERS define is a sort of external include guard.
This patch adds include guards to the few files in include/coff that
were missing one, and then removes the PEI_HEADERS workaround and the
redundant includes.
I didn't see anything in these files that indicated that
double-inclusion would be useful, so it seems to me that this approach
is ok.
Tested by rebuilding with --enable-targets=all.

breaks building of bfp opcodes files.

Here, bfd_coff_aoutsz must match coff_swap_aouthdr_out otherwise we

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

fuzzers. I suspect x86_64 COFF is still broken after this fix, and

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.

bfd_perform_relocation should not have special case target code. This
patch moves the code that was there for x86_64 PE linking to ELF
output into the x86_64 PE howto special function, correcting that
function for linking to targets other than ELF too. The fixes in
bfd_perform_relocation were over-complicated due to needing to
compensate for things that had already gone wrong in coff_amd64_reloc.
In particular, an adjustment for pc-relative relocs was done in a way
that meant adjustment for things related to symbol offsets was lost.
I think those two things are orthogonal, but who knows with COFF where
addends and symbol values are found randomly in the section contents.
Note that linking natively to an x86_64 PE output relocates by
coff_pe_amd64_relocate_section, which does not use arelent relocs or
bfd_perform_relocation, but be aware of coff_amd64_rtype_to_howto
hacking addends for relocations. The adjustments for a particular
relocation type there and in coff_amd64_reloc ought to match after
taking into consideration CALC_ADDEND. They don't. For example,
the pc-relative adjustment for R_PCRWORD is 2 bytes in
coff_amd64_reloc and 4 bytes in coff_amd64_rtype_to_howto.

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.

and other tidies. I think it's better to default to passing the
section to bfd_octets_per_byte, even in cases where we know it won't
make a difference.
A number of the coff reloc functions used bfd_octets_per_byte wrongly,
not factoring it into the offset into the data buffer. As it happens,
the targets using those files always had bfd_octets_per_byte equal to
one, so there wasn't any detectable wrong behaviour. However, it is
wrong in the source and might cause trouble for anyone creating a new
target. Besides fixing that, the patch also defines OCTETS_PER_BYTE
as one in target files where that is appropriate.
