Since this file calls abort() now, we need to include stdlib.h for
its prototype.

The only insn requiring a truly 16-bit PC-relative relocation outside of
16-bit mode is XBEGIN (with an operand size override). For it, the
relocation generated should behave similar to 8- and (for 64-bit) 32-bit
PC-relatives ones, i.e. be checked for a signed value to fit the field.
This same mode is also correct for 16-bit code. Outside of 16-bit code,
branches with operand size overrides act in a truly PC-relative way only
when living in the low 32k of address space, as they truncate rIP to 16
bits. This can't be expressed by a PC-relative relocation.
Putting in place a new testcase, I'd like to note that the two existing
ones (pcrel16 and pcrel16abs) appear to be pretty pointless: They don't
expect any error despite supposedly checking for overflow, and in fact
there can't possibly be any error for the
- former since gas doesn't emit any relocation in the first place there,
- latter because the way the relocation gets expressed by gas doesn't
allow the linker to notice the overflow; it should be detected by gas
if at all, but see above (an error would be reported here for x86-64
afaict, but this test doesn't get re-used there).

The change implementing the .persistent family of sections broke the
existing support for the .persistent.bss section in the compiler:
int a __attribute__ ((section (".persistent.bss")));
t.s: Assembler messages:
t.s:4: Warning: setting incorrect section type for .persistent.bss
The compiler encodes it as @nobits but the assembler expects @progbits.
The assembler is incorrect and should treat the section like the compiler.

These are marker relocations, so together with their bit size being zero
their byte size should be zero as well. This is expressed by a value of

The local ".L0" symbol are usually generated to mark where the
auipc instruction is, and clang also uses ".LBB" to do the same
thing. Besides, clang also uses the empty name symbols for label
differences. Arm surpress their mapping symbols by regarding them
as special symbols, and MIPS surpress all local symbols. Therefore,
RISC-V probably need to surpress the local and empty name symbols
for nm and related tools. User can use "--special-syms" to show
these surpressed symbols.

The linker does not care the default versions of the extensions, since
it does not have the default ISA spec setting. Therefore, linker won't
insert the implicit extensions for the input objects. But we used to
insert the i-ext as the explicit extension, even if the e-ext is set.
This causes linker to report "cannot find default versions of the ISA
extension `i'" errors when linking the input objects with e-ext.
This patch fixes the above linker problem, and also remove the confused
riscv_ext_dont_care_version function. Unless these "dont care" extensions
are set in the input architecture explicitly, otherwise we always insert
them as the implicit ones. Afterwards, let riscv_arch_str1 surpress them
not to output to the architecture string if their versions are
RISCV_UNKNOWN_VERSION.

The original discussion is as follows,
https://github.com/riscv/riscv-isa-manual/issues/637
I never considered the prefixes may have multiple letters, like zxm.
But the ISA spec has been updated for a long time that I haven't noticed.
This patch rewrites the part of architecture parser to support parsing
the multi-letter prefixes. Besides, I also improve the parser to report
errors in details. One of the most obvious improvement is - Do not parse
the prefixed extensions according to the orders in the parse_config.
If we do so, then we used to get "unexpected ISA string at end" errors,
but the message is a little bit hard to know what is happening. I Remove
the confused message, and let riscv_parse_prefixed_ext to report the details.

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.

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 ece5ef60797f but
since bfd_boolean was an int typedef I lazily left all the ELF
relocate_section functions as returning bfd_boolean, except the SPU
one. In order to use _Bool or bool in place of bfd_boolean we need to
be fussy about the return types.

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.
bfd/ChangeLog
2021-03-26 Keith Seitz <keiths@redhat.com>
* elfcore.h (_bfd_elf_core_find_build_id): Seek file
offset of program headers after calling elf_read_notes.

Old enough glibc has an (unguarded) declaration of index() in string.h,
which triggers a "shadows a global declaration" warning.

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 994b2513281 in elf_create_symbuf.
3. Ignore section symbols only when matching non-debugging sections or
linkonce section with comdat section.
