X_unsigned being clear does not indicate a negative number; it merely
indicates a signed one (whose sign may still be clear). Amend two uses
by an actual value check.
The 'Zvkt' extension is listed on the added extensions in the GNU Binutils
version 2.41 (see binutils/NEWS). However, the support of this extension
was actually missing.
This commit adds actual support of this extension and adds implications
from 'Zvkn' and 'Zvks' superset extensions.
bfd/ChangeLog:
* elfxx-riscv.c (riscv_implicit_subsets) Add implications from
'Zvkn' and 'Zvks'. (riscv_supported_std_z_ext): Add 'Zvkt' to
the supported extension list.
MIPS: Support `-gnuabi64' target triplet suffix for 64-bit Linux targets
Make the n64 ABI the default for 64-bit Linux targets specified with
`-gnuabi64' suffix included in the target triplet, for configurations
such as the Debian mips64el and mips64r6el ports. Adjust testsuite
configuration accordingly.
There are the following regressions with the new target triplet:
The `readelf' issue comes from a difference in section headers produced
that the `binutils/testsuite/binutils-all/readelf.s-64' pattern template
does not match. While there has been a precedent it does not appear to
me that there is a clear advantage from adding more and more variations
to the template rather than forking the existing template into multiple
ones for a more exact match. So this is best deferred to a separate
discussion.
The MIPS reloc estimation issue is an actual bug in `objdump', which
discards a number of trailing entries from output here for n64 composed
relocations:
DYNAMIC RELOCATION RECORDS
OFFSET TYPE VALUE
0000000000000000 R_MIPS_NONE *ABS*
0000000000000000 R_MIPS_NONE *ABS*
and consequently `ld/testsuite/ld-mips-elf/reloc-estimate-1.d' does not
match even though ELF output produced is correct according to `readelf':
Relocation section '.rel.dyn' at offset 0x10400 contains 2 entries:
Offset Info Type Sym. Value Sym. Name
000000000000 000000000000 R_MIPS_NONE Type2: R_MIPS_NONE Type3: R_MIPS_NONE
000000010000 000300001203 R_MIPS_REL32 0000000000010010 foo@@V2 Type2: R_MIPS_64 Type3: R_MIPS_NONE
As a genuine bug this has to be handled separately.

MIPS n64 ABI has a peculiarity where all relocations are composed of
three, with subsequent relocation types set to R_MIPS_NONE if further
calculation is not required. Example output produced by `readelf' and
`objdump' for such relocations is:
Offset Info Type Sym. Value Sym. Name + Addend
000000000000 000800000002 R_MIPS_32 0000000000000000 foo + 0 Type2: R_MIPS_NONE Type3: R_MIPS_NONE
and:
OFFSET TYPE VALUE
0000000000000000 R_MIPS_32 foo
0000000000000000 R_MIPS_NONE *ABS*
0000000000000000 R_MIPS_NONE *ABS*
respectively. The presence of these extra R_MIPS_NONE entries is not
relevant for generic or even some MIPS tests, so optionally match them
with the respective dump patterns, also discarding `xfail' annotation
for MIPS/OpenBSD targets from gas/elf/missing-build-notes.d, removing
these regressions:
Several MIPS test cases are suitable for the n64 ABI if not for the
extra leading zeros or spaces in addresses not handled by dump patterns.
Match the characters then, removing these regressions:
ld/
* testsuite/ld-mips-elf/jaloverflow-2.d: Match extra leading
zeros and spaces with addresses as appropriate.
* testsuite/ld-mips-elf/jalx-1.d: Likewise.
* testsuite/ld-mips-elf/reloc-estimate-1.d: Likewise.
