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.
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:
mips64-linux-gnuabi64 +FAIL: readelf -S bintest
mips64-linux-gnuabi64 +FAIL: MIPS reloc estimation 1
mips64el-linux-gnuabi64 +FAIL: readelf -S bintest
mips64el-linux-gnuabi64 +FAIL: MIPS reloc estimation 1
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.

IRIX 6 does not have MIPS16 stub section support in its n32 linker
scripts, causing such input sections to be propagated to the respective
output sections rather than `.text', causing dump pattern mismatches.
Expect IRIX 6 to fail with n32 testing then, removing this regression:
mips-sgi-irix6 -FAIL: MIPS16 interlinking for local functions 1 (n32)
We may choose to update IRIX 6 n32 linker scripts sometime, as it seems
a harmless change.

The MIPS16 interlinking test for local functions expects to be assembled

Use the per-ABI framework then to run the test explicitly for o32 and
n32 ABIs only, replacing the `-mips4' option from the `as' tag with
`.module mips4' pseudo-op within the source itself so as to avoid
assembly errors:

IRIX targets do not enable the production of a `.pdr' section in GAS by
default, which causes a failure with the `attr-gnu-4-10' test case due
to a difference resulting in the number and indices of sections produced
in linker output.
As the presence or absence of this section is not relevant to this test
case, just enable it unconditionally, fixing these regressions:
mips-sgi-irix5 -FAIL: ld-mips-elf/attr-gnu-4-10
mips-sgi-irix6 -FAIL: ld-mips-elf/attr-gnu-4-10
ld/
* testsuite/ld-mips-elf/attr-gnu-4-10.d: Add `as' tag with

(cherry picked from commit d4e5281f03)
The `mips-sgi-irix6' target only supports IRIX linker emulations, but
most JALR relaxation tests request the relevant traditional emulation
instead, causing a link failure:
./ld-new: unrecognised emulation mode: elf32btsmipn32
Supported emulations: elf32bmipn32 elf32bsmip elf64bmip
This is clearly an omission from the conversion to use the per-ABI
framework made with commit 78da84f994 ("MIPS/LD/testsuite: Correct
mips-elf.exp test ABI/emul/endian arrangement"). These tests are also
endianness agnostic, which was missed in the conversion as well.
Remove the unnecessary explicit ABI and endianness options then and rely
on the per-ABI framework to get things right, removing this regression:
mips-sgi-irix6 -FAIL: MIPS relax-jalr-shared n32

* testsuite/ld-mips-elf/relax-jalr-n32-shared.d: Remove flags

(cherry picked from commit 94052ee4cc)
There are only n64 linker emulations included with `mips64*-*-openbsd*'
targets, however the unaligned JALX tests insist on running across all
targets and force the n32 ABI, causing link errors with the targets
concerned, e.g.:
./ld-new: tmpdir/unaligned-jalx-0.o: ABI is incompatible with that of the selected emulation
./ld-new: failed to merge target specific data of file tmpdir/unaligned-jalx-0.o
./ld-new: tmpdir/unaligned-insn.o: ABI is incompatible with that of the selected emulation
./ld-new: failed to merge target specific data of file tmpdir/unaligned-insn.o
Convert the tests then to use the per-ABI framework and run them for the
o32 and n32 ABIs, removing these regressions:
mips64-openbsd -FAIL: MIPS JALX to unaligned symbol 0
mips64-openbsd -FAIL: MIPS JALX to unaligned symbol 1

In ld/emulparams/elf64bmip-defs.sh there is no explicit handling of the
`.interp' section, which causes it to be positioned in output at an odd
place.
Let's include it with INITIAL_READONLY_SECTIONS, just like o32/n32 do,
fixing a regression from commit 5a8e7be242 ("INITIAL_READONLY_SECTIONS
in elf.sc"), where the handling of n64 was missed due to an unfortunate
sequence of events where ld/emulparams/elf64bmip-defs.sh was only added
with commit 94bb04b3c6 ("Use .reginfo rather than .MIPS.options in n32
