This patch add supports for FEAT_SPECRES2 "Enhanced speculation
restriction instructions" adding the "cosp" instruction.
This is mandatory v8.9-a/v9.4-a and optional v8.0-a+/v9.0-a+. It is
enabled by the +predres2 march flag.

R_LARCH_CALL36 is used for medium code model function call pcaddu18i+jirl, and
these two instructions must adjacent.

The description of instructions 'th.fmv.hw.x' and 'th.fmv.x.hw' of the
XTheadFmv extension in T-Head specific is incorrect, and it also has
some impact on the implementation of the binutils, so this patch
corrects this.

I've reimplemented the .debug_names code in GDB -- it was quite far
from being correct, and the new implementation is much closer to what
is specified by DWARF.
However, the new writer in GDB needs to emit some symbol properties,
so that the reader can be fully functional. This patch adds a few new
DW_IDX_* constants, and tries to document the existing extensions as
well. (My patch series add more documentation of these to the GDB
manual as well.)

Add support for jump visualization for the s390 architecture in
disassembly:
objdump -d --visualize-jumps ...
Annotate the (conditional) jump and branch relative instructions with
information required for jump visualization:
- jump: Unconditional jump / branch relative.
- condjump: Conditional jump / branch relative.
- jumpsr: Jump / branch relative to subroutine.
Unconditional jump and branch relative instructions are annotated as
jump.
Conditional jump and branch relative instructions, jump / branch
relative on count/index, and compare and jump / branch relative
instructions are annotated as condjump.
Jump and save (jas, jasl) and branch relative and save (bras, brasl)
instructions are annotated as jumpsr (jump to subroutine).
Provide instruction information required for jump visualization during
disassembly.
The instruction type is provided after determining the opcode.
For non-code it is set to dis_noninsn. Otherwise it defaults to
dis_nonbranch. No annotation is done for data reference instructions
(i.e. instruction types dis_dref and dis_dref2). Note that the
instruction type needs to be provided before printing of the
instruction, as it is used in print_address_func() to translate the
argument value into an address if it is assumed to be a PC-relative
offset. Note that this is never the case on s390, as
print_address_func() is only called with addresses and never with
offsets.
The target of the (conditional) jump and branch relative instructions
is provided during print, when the PC relative operand is decoded.
include/
* opcode/s390.h: Define opcode flags to annotate instruction
class information for jump visualization:
S390_INSTR_FLAG_CLASS_BRANCH, S390_INSTR_FLAG_CLASS_RELATIVE,
S390_INSTR_FLAG_CLASS_CONDITIONAL, and
S390_INSTR_FLAG_CLASS_SUBROUTINE.
Define opcode flags mask S390_INSTR_FLAG_CLASS_MASK for above
instruction class information.
Define helpers for common instruction class flag combinations:
S390_INSTR_FLAGS_CLASS_JUMP, S390_INSTR_FLAGS_CLASS_CONDJUMP,
and S390_INSTR_FLAGS_CLASS_JUMPSR.
opcodes/
* s390-mkopc.c: Add opcode flags to annotate information
for jump visualization: jump, condjump, and jumpsr.
* s390-opc.txt: Annotate (conditional) jump and branch relative
instructions with information for jump visualization.
* s390-dis.c (print_insn_s390, s390_print_insn_with_opcode):
Provide instruction information for jump visualization.

Back then when the support for the RISC-V vector crypto extensions
was merged, the specification was frozen, but not ratified.
A frozen specification is allowed to change within tight bounds
before ratification and this has happend with the vector crypto
extensions.
The following changes were applied:
* A new extension Zvkb was defined, which is a strict subset of Zvbb.
* Zvkn and Zvks include now Zvkb instead of Zvbb.
This patch implements these changes between the frozen and the
ratified specification.
Note, that this technically an incompatible change of Zvkn and Zvks,
but I am not aware of any project that depends on the currently
implemented behaviour of Zvkn and Zvks. So this patch should be fine.

The following patch attempts to use x86 SHA ISA if available to speed
up in my testing about 2.5x sha1 build-id processing (in my case on
AMD Ryzen 5 3600) while producing the same result.
I believe AArch64 has similar HW acceleration for SHA1, perhaps it
could be added similarly.
Note, seems lld uses BLAKE3 rather than md5/sha1. I think it would be
a bad idea to lie to users, if they choose --buildid=sha1, we should
be using SHA1, not some other checksum, but perhaps we could add some other
--buildid= styles and perhaps make one of the new the default.
Tested on x86_64-linux, both on Intel i9-7960X (which doesn't have
sha_ni ISA support) without/with the patch and on AMD Ryzen 5 3600
(which does have it) without/with the patch.

T-Head has a range of vendor-specific instructions ([2]).
Therefore it makes sense to group them into smaller chunks
in form of vendor extensions.
This patch adds the "XTheadVector" extension, a collection of
T-Head-specific vector instructions. The 'th' prefix and the
"XTheadVector" extension are documented in a PR for the RISC-V
toolchain conventions ([1]).
Here are some things that need to be explained:
The "XTheadVector" extension is not a custom-extension, but
a non-standard non-conforming extension. The encoding space
of the "TheadVector" instructions overlaps with those of
the 'V' extension. This encoding space conflict is not on
purpose, but the result of issues in the past that have
been resolved since. Therefore, the "XTheadVector" extension
and the 'V' extension are in conflict.

Just the lightest modifications about this, without any further checks and
considering --emit-relocs. We will need to improve it in the future, but
first do this to avoid conflicts between linker internal relocations and the
new definition of psabi. For example, TLSDESC relocs.
Passed riscv-gnu-toolchain regressions, so should be safe enough to commit.

Within the groups L{B,BU,H,HU,W,WU,D}, S{B,H,W,D}, FL{H,W,D,Q}, and
FS{H,W,D,Q} the sole difference between the handling is the insn
mnemonic passed to the common handling functions. The intended mnemonic,
however, can easily be retrieved. Furthermore leverags that Sx and FSx
are then handled identically, too, and hence their cases can also be
folded.

This patch adds support for Guarded control stack data synchronization
instruction (GCSB DSYNC). This instruction is allocated to existing
HINT space and uses the HINT number 19 and to match this an entry is
added to the aarch64_hint_options array.

This patch adds for Guarded Control Stack Extension (GCS) extension. GCS feature is
optional from Armv9.4-A architecture and enabled by passing +gcs option to -march
(eg: -march=armv9.4-a+gcs) or using ".arch_extension gcs" directive in the assembly file.
Also this patch adds support for GCS instructions gcspushx, gcspopcx, gcspopx,
gcsss1, gcsss2, gcspushm, gcspopm, gcsstr and gcssttr.

.L1
...

Some older kernels cannot handle the newly generated R_LARCH_32/64_PCREL,
so the assembler generates R_LARCH_ADD32/64+R_LARCH_SUB32/64 by default,
and use the assembler option mthin-add-sub to generate R_LARCH_32/64_PCREL
as much as possible.
The Option of mthin-add-sub does not affect the generation of R_LARCH_32_PCREL
relocation in .eh_frame.

This patches adds new bsefi and bsifi instructions.
BSEFI- The instruction shall extract a bit field from a
register and place it right-adjusted in the destination register.
The other bits in the destination register shall be set to zero.
BSIFI- The instruction shall insert a right-adjusted bit field
from a register at another position in the destination register.
The rest of the bits in the destination register shall be unchanged.
Further documentation of these instructions can be found here:

This patch adds a mechanism for system register name alias detection
to register-matching mechanisms.
A new `F_REG_ALIAS' flag is added to the set of register flags and
used to label which entries in aarch64_sys_regs[] correspond to
aliases (and thus which CPENC values are non-unique in this array).
Where this is used is, for example, in `aarch64_print_operand' where,
in the case of system register decoding, the aarch64_sys_regs[] array
is iterated through until a match in CPENC value is made and the first
match accepted. If insufficient care is given in the ordering of
system registers in this array, the alias is encountered before the
"real" register and used incorrectly as the register name in the
disassembled output.
With this flag and the new `aarch64_sys_reg_alias_p' test, search
candidates corresponding to aliases can be conveniently skipped over.
One concrete example of where this is useful is with the
`trcextinselr0' system register. It was initially placed in the
system register list before `trcextinselr', in contrast to a more
natural alphabetical order.
include/ChangeLog:
* opcode/aarch64.h: add `aarch64_sys_reg_alias_p' prototype.
opcodes/ChangeLog:
* aarch64-opc.c (aarch64_sys_reg_alias_p): New.
(aarch64_print_operand): add aarch64_sys_reg_alias_p check.
(aarch64_sys_regs): Add F_REG_ALIAS flag to "trcextinselr"
entry.
* aarch64-opc.h (F_REG_ALIAS): New.

The PLT entry in executables and shared libraries contains an indirect
branch, like
jmp *foo@GOTPCREL(%rip)
push $index_foo
jmp .PLT0
or
endbr64
jmp *foo@GOTPCREL(%rip)
NOP padding
which is used to branch to the function, foo, defined in another object.
Each R_X86_64_JUMP_SLOT relocation has a corresponding PLT entry.
The dynamic tags have been added to the x86-64 psABI to mark such PLT
entries:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/commit/6d824a52a42d173eb838b879616c1be5870b593e
Add an x86-64 linker option, -z mark-plt, to mark PLT entries with
#define DT_X86_64_PLT (DT_LOPROC + 0)
#define DT_X86_64_PLTSZ (DT_LOPROC + 1)
#define DT_X86_64_PLTENT (DT_LOPROC + 3)
1. DT_X86_64_PLT: The address of the procedure linkage table.
2. DT_X86_64_PLTSZ: The total size, in bytes, of the procedure linkage
table.
3. DT_X86_64_PLTENT: The size, in bytes, of a procedure linkage table
entry.
and set the r_addend field of the R_X86_64_JUMP_SLOT relocation to the
memory offset of the indirect branch instruction. The dynamic linker
can use these tags to update the PLT section to direct branch.
