Defining the VSX2 and VSX3 selection based on cpu bits also lets the

Many x86 instructions have more than one encodings. Assembler picks
the default one, usually the shortest one. Although the ".s", ".d8"
and ".d32" suffixes can be used to swap register operands or specify
displacement size, they aren't very flexible. This patch adds pseudo
prefixes, {xxx}, to control instruction encoding. The available
pseudo prefixes are {disp8}, {disp32}, {load}, {store}, {vex2}, {vex3}
and {evex}. Pseudo prefixes are preferred over the ".s", ".d8" and
".d32" suffixes, which are deprecated.

Currently, the -maltivec and -mvsx GAS options enable *all* of the altivec
and vsx instructions respecitively that have ever been added. This is in
constract to GCC's -maltivec and -mvsx options, which only enable the oldest
(ie, first) set of altivec and vsx instructions. This patch changes GAS to
mimic GCC's behaviour with respect to -maltivec and -mvsx and it solves a

Just like REX.W affects operand size of the implicit rAX/rDX inputs to
PCMPESTR{I,M}, VEX.W does for VPCMPESTR{I,M}. Allow Q or L suffixes on
the instructions.
Similarly the disassembler needs to be adjusted to no longer require
VEX.W to be zero for the instructions to be valid, and to emit proper
suffixes.
Note, however, that this doesn't address the problem of there being no
way to control (at least) {,E}VEX.W for 32- or 16-bit code. Nor does it
address the problem of the many WIG instructions not getting properly
disassembled when VEX.W=1.
This patch supports some additions to the SVE architecture prior to
its public release.

Opcodes F6/1 and F7/1 are aliases of F6/0 and F7/0 in all modes. This
complements commit 8b89fe14b5 ("X86: Decode opcode 0x82 as opcode 0x80
in 32-bit mode"), just that here 64-bit mode is also covered.
This adds support of new instructions to the S/390 specific parts.
The important feature of the new instruction set is the support of
single and extended precision floating point vector operations.
Note: arch12 is NOT the official name of the new CPU. It just
continues the series of archXX options supported as alternate names.
The archXX terminology refers to the edition number of the Principle
of Operations manual. The official CPU name will be added later while
keeping support of the arch12 for backwards compatibility.
No testsuite regressions.
Committed to mainline.

With this change an architecture level bump due to assembly ASIs will show
up as a warning/error depending on options passed to gas.
Tested with sparc64-linux-gnu, and it does not introduce any regressions.
gas/ChangeLog:
Add support for associating SPARC ASIs with an architecture level.
* config/tc-sparc.c (parse_sparc_asi): New encode SPARC ASIs.
opcodes/ChangeLog:
Add support for associating SPARC ASIs with an architecture level.
* include/opcode/sparc.h (sparc_asi): New sparc_asi struct.
* opcodes/sparc-opc.c (asi_table): Updated asi_table and encoding/
decoding of SPARC ASIs.
No such ModR/M-less opcode has ever existed in public documentation
afaict, so I can't see why it had been added in the first place.
Furthermore opcode 77 is special only with implied prefix 0F.
Commit 93562a343c ("[AArch64] PR target/20666, fix wrong encoding of
new introduced BFC pseudo") changed the destination operand to 0,
making the whole function invocation a no-op. We really want to copy
operand 0 (a register) to operand 1 (an immediate before coming here),
even if right now this likely is only a latent bug.
This patch adds the SVE-specific system registers.
opcodes/
* aarch64-opc.c (aarch64_sys_regs): Add SVE registers.
(aarch64_sys_reg_supported_p): Handle them.
gas/
* testsuite/gas/aarch64/sve-sysreg.s,
testsuite/gas/aarch64/sve-sysreg.d,
testsuite/gas/aarch64/sve-sysreg-invalid.d,

opcodes * arc-regs.h: Distinguish some of the registers different on
ARC700 and HS38 cpus.
gas * testsuite/gas/arc/st.d: Update for 0xe having a name now
This stops powerpc gas blithely accepting such nonsense as
"addi %f4,%cr3,%r31".
