Jan Beulich 1b193f0b12 x86: drop bogus NoAVX
These are meaningful only for insns with CpuSSE* (and a few other Cpu*)
attribute.

Jan Beulich f2f6a710f4 x86: avoid SSE check for LDMXCSR/STMXCSR
Neither touches any XMM register, so the check is pointless. It is imo
even questionable whether in SSE2AVX mode the two should be converted to
their AVX counterparts.

Jan Beulich 38e314eb06 x86: drop FloatD
It can be expressed by D, when making the consumer look at operand size
to tell apart both uses.

Jan Beulich 2907c2f555 x86: bogus VMOVD with 64-bit operands should only allow for registers
These templates exist solely to satisfy gcc's needs, and gcc only
produces these with register operands.

Jan Beulich 73053c1fc4 x86: fold AVX vcvtpd2ps memory forms
This requires a change to ModR/M handling: Recording of displacement
types must not discard operand size information. Change the respective
code to alter only .disp<N>.

H.J. Lu 8305403a1f x86: Encode AVX256/AVX512 vpsub[bwdq] with VEX128/EVEX128
When 2 source registers are identical, AVX256 and AVX512 vpsub[bwdq]

H.J. Lu b6f8c7c452 x86: Add -O[2|s] assembler command-line options
On x86, some instructions have alternate shorter encodings:

1. When the upper 32 bits of destination registers of

andq $imm31, %r64
testq $imm31, %r64
xorq %r64, %r64
subq %r64, %r64

known to be zero, we can encode them without the REX_W bit:

andl $imm31, %r32
testl $imm31, %r32
xorl %r32, %r32
subl %r32, %r32

This optimization is enabled with -O, -O2 and -Os.
2. Since 0xb0 mov with 32-bit destination registers zero-extends 32-bit
immediate to 64-bit destination register, we can use it to encode 64-bit
mov with 32-bit immediates.  This optimization is enabled with -O, -O2
and -Os.
3. Since the upper bits of destination registers of VEX128 and EVEX128
instructions are extended to zero, if all bits of destination registers
of AVX256 or AVX512 instructions are zero, we can use VEX128 or EVEX128
encoding to encode AVX256 or AVX512 instructions.  When 2 source
registers are identical, AVX256 and AVX512 andn and xor instructions:

VOP %reg, %reg, %dest_reg

can be encoded with

VOP128 %reg, %reg, %dest_reg

This optimization is enabled with -O2 and -Os.
4. 16-bit, 32-bit and 64-bit register tests with immediate may be
encoded as 8-bit register test with immediate.  This optimization is
enabled with -Os.

This patch does:

1. Add {nooptimize} pseudo prefix to disable instruction size
optimization.
2. Add optimize to i386_opcode_modifier to tell assembler that encoding
of an instruction may be optimized.

Jan Beulich cbda583ada x86: fix Disp8 handling for scalar AVX512_4FMAPS insns
Just like their packed counterparts the memory operand is always 16
bytes wide, and the Disp8 scaling is the same for all of them. (As a
side note: I'm also surprised by there being AVX512VL variants of
these as well as the AVX512_4VNNIW ones - the SDM doesn't define any
such.)

Adjust the test cases also for the packed forms to actually live up to
their promise of testing correct Disp8 encoding.

H.J. Lu 704a705d7a x86: Properly encode vmovd with 64-bit memeory
For historical reason, we allow movd/vmovd with 64-bit register and
memeory operands.  But for vmovd, we failed to handle 64-bit memeory
operand.  This has been gone unnoticed since AT&T syntax always treats
memory operand as 32-bit memory.  This patch properly encodes vmovd
with 64-bit memeory operands.  It also removes AVX512 vmovd with 64-bit
operands since GCC has

    case TYPE_SSEMOV:
      switch (get_attr_mode (insn))
        {
        case MODE_DI:
          /* Handle broken assemblers that require movd instead of movq.  */
          if (!HAVE_AS_IX86_INTERUNIT_MOVQ
              && (GENERAL_REG_P (operands[0]) || GENERAL_REG_P (operands[1])))
            return "%vmovd\t{%1, %0|%0, %1}";
          return "%vmovq\t{%1, %0|%0, %1}";

and all AVX512 GNU assemblers set HAVE_AS_IX86_INTERUNIT_MOVQ, GCC won't
generate AVX512 vmovd with 64-bit operand.

Jan Beulich dc821c5f9a x86: replace Reg8, Reg16, Reg32, and Reg64
Use a combination of a single new Reg bit and Byte, Word, Dword, or
Qword instead.

Besides shrinking the number of operand type bits this has the benefit
of making register handling more similar to accumulator handling (a
generic flag is being accompanied by a "size qualifier"). It requires,
however, to split a few insn templates, as it is no longer correct to
have combinations like Reg32|Reg64|Byte. This slight growth in size will
hopefully be outweighed by this change paving the road for folding a
presumably much larger number of templates later on.

Jan Beulich 7ac2002247 x86: derive DispN from BaseIndex
BaseIndex implies - with the exception of string instructions the
optional presence of a displacement. This is almost completely uniform
for all instructions (the sole exception being MPX ones, which don't
allow 16-bit addressing and hence Disp16), so there's no point in
explicitly stating this in the main opcode table. Drop those explict
specifications in favor of adding logic to i386-gen, shrinking the
table size quite a bit and hence making it more readable.

The opcodes/i386-tbl.h changes are due to a few cases where pointless
Disp* still hadn't been removed from their insns.

Jan Beulich 897e603cb9 x86: {f,}xsave64 / {f,}xrstor64 / xsaveopt64 should not allow q suffix
Just like is the case for xsave{s,c}64 and xrstors64 already. I wonder
though why xsave{s,c} and xrstors don't allow for the q suffix, other
than the other insns without the "64" suffix do.

H.J. Lu 86fa6981e7 X86: Add pseudo prefixes to control encoding
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.

Jan Beulich 15c7c1d8a5 x86: fix handling of 64-bit operand size VPCMPESTR{I,M}
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.
