83c79df86b C99 bfd configury 
Certain library headers and functions are required by C99.  This
removes configure tests for them.  The patch also removes AC_ISC_POSIX
and AC_HEADER_DIRENT, which the autoconf manual states are obsolescent.
sys/time.h is no longer tangled up with time.h so it can be handled by
the gprof configure.

	* configure.ac: Don't check for long long or long double type.
	Don't check for alloca.h, limits.h, stddef.h, stdlib.h, string.h,
	strings.h, time.h, wchar.h, wctype.h or sys/time.h.  Don't check
	for strtoull, free, malloc, realloc, getenv, strstr, snprintf,
	vsnprintf, strlen or setitimer.  Sort AC_CHECK_DECLS.
	(AC_ISC_POSIX): Don't invoke.
	(AC_HEADER_TIME, AC_HEADER_DIRENT, ACX_HEADER_STRING): Likewise.
	* sysdep.h: Remove many HAVE_*_H checks and fallback declarations.
	Do test HAVE_SYS_TYPES_H.  Don't include sys/time.h.  Reorder
	header order as per automake AC_INCLUDES_DEFAULT.
	* bfd-in.h: Include inttypes.h unconditionally.
	* bfd.c (_bfd_doprnt, _bfd_doprnt_scan): Assume long long and
	long double are available.
	(bfd_scan_vma): Assume long long and strtoull are available.
	* elflink.c: Include limits.h unconditionally.
	* elfnn-riscv.c: Likewise.
	* wasm-module.c: Likewise.
	* hpux-core.c: Include dirent.h unconditionally.
	* trad-core.c: Likewise.
	* hosts/x86-64linux.h: Include stdlib.h unconditionally.
	* peXXigen.c: Remove HAVE_WCHAR_H and HAVE_WCTYPE_H checks.
	* elf32-m68hc1x.c: Don't include alloca-conf.h.
	* elf64-hppa.c: Likewise.
	* som.c: Likewise.
	* wasm-module.c: Likewise.
	* xsym.c: Likewise.
	* bfd-in2.h: Regenerate.

74edb473c9 PE/Windows x86_64: Fix weak undef symbols after image base change 
The change in PR19011 changed the image load address from being in the lower
32-bit address space to the higher 64-bit address space.

However when you have a weak undef symbol which stays undef at the end of
linking the linker has to resolve this (Windows loader does not support undef
symbols).  As such typically these would resolve to 0.

The relocation used for these weak symbols are the normal 32-bit PC_REL call
relocs.  So when doing the overflow check LD checks if the distance between the
symbol and the call is within range.  However now that the load address is
> 32-bits and the symbol val is 0 this overflow check will always fail.

As such the linker gives a bogus error.  This patch makes the linker not emit
the overflow failure but chooses to still let the check be performed (as it's
mid-end code).

One down side of this is that it does break the common convention that the call
be to sym at 0x0. i.e. before you'd get

      401015:   74 05                   je     40101c
      401017:   e8 e4 ef bf ff          callq  0

and now you get

   140001015:   74 05                   je     14000101c
   140001017:   e8 e4 ef ff bf          call   100000000

since the call is PC_REL there's no way to get the range large enough to
resolve to 0.  As such I have chosen to leave it as the furthest simple range
that we can still represent.

By only ignoring the error we leave the symbol value itself to still be 0
such that the if(<symbol>) checks still work correctly.

63b4cc53dc TRUE/FALSE simplification 
There is really no need to write code like "foo != 0 ? TRUE : FALSE"
unless we had stupidly defined FALSE as something other than 0 or TRUE
as something other than 1.  The simpler "foo != 0" does just as well.
Similarly "(condition == TRUE)" or "(condition == FALSE) can be
simplified to "(condition)" and "(!condition)" respectively.

I'll note that there is reason to use "integer_expression != 0" when
assigning a bfd_boolean rather than the simpler "integer_expression",
if you expect the variable to have 0 or 1 value.  It's probably even a
good idea to not rely on implicit conversion if bfd_boolean were _Bool.

This functions was changed to return an int in commit ece5ef6079 but
since bfd_boolean was an int typedef I lazily left all the ELF

be fussy about the return types.

ff5b3e1458 Save/restore file offset while reading notes in core file 
A recent bug (RH BZ 1931344) has exposed a bug in the core file
build-ID support that I introduced a while ago. It is pretty
easy to demonstate the problem following a simplified procedure
outlined in that bug:

[shell1]
shell1$ /usr/libexec/qemu-kvm

[shell2]
shell2$ pkill -SEGV -x qemu-kvm

[shell1]
Segmentation fault (core dumped)

Load this core file into GDB without specifying an executable
(an unfortunate Fedora/RHEL-ism), and GDB will inform the user
to install debuginfo for the "missing" executable:

$ gdb -nx -q core.12345
...
Missing separate debuginfo for the main executable file
Try: dnf --enablerepo='*debug*' install /usr/lib/debug/.build-id/e2/e9c66d3117fb2bbb5b2be122f04f2664e5df54
Core was generated by `/usr/libexec/qemu-kvm'.
Program terminated with signal SIGSEGV, Segmentation fault.
...

The suggested build-ID is actaully for gmp not qemu-kvm. The problem
lies in _bfd_elf_core_find_build_id, where we loop over program headers
looking for note segments:

  /* Read in program headers and parse notes.  */
  for (i = 0; i < i_ehdr.e_phnum; ++i, ++i_phdr)
    {
      Elf_External_Phdr x_phdr;

      if (bfd_bread (&x_phdr, sizeof (x_phdr), abfd) != sizeof (x_phdr))
        goto fail;
      elf_swap_phdr_in (abfd, &x_phdr, i_phdr);

      if (i_phdr->p_type == PT_NOTE && i_phdr->p_filesz > 0)
        {
          elf_read_notes (abfd, offset + i_phdr->p_offset,
                          i_phdr->p_filesz, i_phdr->p_align);

          if (abfd->build_id != NULL)
            return TRUE;
        }

elf_read_notes uses bfd_seek to forward the stream to the location of
the note segment. When control returns to _bfd_elf_core_fild_build_id,
the stream is no longer in the location looking at program headers, and
all subsequent reads will read from the wrong file offset.

To fix this, this patch marks the stream location and ensures
that it is restored after elf_read_notes is called.

3818d4ab06 elf: Handle .gnu.debuglto_.debug_* sections 
commit 994b251328
Author: H.J. Lu <hjl.tools@gmail.com>
Date:   Sun Jan 17 20:01:16 2021 -0800

    ld/elf: Ignore section symbols when matching linkonce with comdat

ignored section symbols when comparing symbols in 2 sections.  Since all
references to debugging sections are done with section symbols, symbols
in debugging sections are ignored and we fail to match symbols in comdat
debugging sections.  Also .gnu.debuglto_.debug_* sections aren't treated
as debugging sections.

1. Treate .gnu.debuglto_.debug_ section as debugging section unless it
is marked with SHF_EXCLUDE.
2. Revert commit 994b251328 in elf_create_symbuf.
3. Ignore section symbols only when matching non-debugging sections or
linkonce section with comdat section.
