2019-09-20x86-64: fix handling of PUSH/POP of segment registerJan Beulich1-2/+4
Commit 21df382b91 ("x86: fold SReg{2,3}") went too far: Folding 64-bit PUSH/POP templates into non-64-bit ones isn't correct, due to the different operand widths, and hence suffixes permitted. Restore the separate templates. Add tests of PUSH/POP with q suffix and %fs/%gs operands to the testsuite. While doing so also add PUSHF/POPF ones _without_ suffix.
2019-08-07x86: drop stray FloatMFJan Beulich1-7/+7
The flag is supposed to be used in templates which allow for both a "short" and a "long" format memory operand. Drop it from templates not matching this pattern. In the control/status word cases it was (ab)used in place of the intended IgnoreSize.
2019-07-16x86: make RegMem an opcode modifierJan Beulich1-35/+38
... instead of an operand type bit: It's an insn property, not an operand one. There's just one actual change to be made to the templates: Most are now required to have the (unswapped) destination go into ModR/M.rm, so VMOVD template needs its opcode adjusted accordingly and its operands swapped. {,V}MOVS{S,D}, otoh, are left alone in this regard, as otherwise generated code would differ from what we've been producing so far (which I don't think is wanted). Take the opportunity and add a missing IgnoreSize to pextrb (leading to an error in 16-bit mode), and take the liberty to once again drop stray IgnoreSize attributes from lines changed and neighboring related ones.
2019-07-16x86: fold SReg{2,3}Jan Beulich1-10/+6
They're the only exception to there generally being no mix of register kinds possible in an insn operand template, and there being two bits per operand for their representation is also quite wasteful, considering the low number of uses. Fold both bits and deal with the little bit of fallout. Also take the liberty and drop dead code trying to set REX_B: No segment register has RegRex set on it. Additionally I was quite surprised that PUSH/POP with the permitted segment registers is not covered by the test cases. Add the missing pieces.
2019-07-01x86: drop Vec_Imm4Jan Beulich1-4/+4
It is pretty wasteful to have a per-operand flag which is used in exactly 4 cases. It can be relatively easily replaced, and by doing so I've actually found some dead code to remove at the same time (there's no case of ImmExt set at the same time as Vec_Imm4).
2019-07-01x86: limit ImmExt abuseJan Beulich1-42/+42
In quite a few cases ImmExt gets used when there's not really any immediate, but rather a degenerate ModR/M byte. ENCL{S,U} show how this case is supposed to be dealt with. Eliminate most abuses, leaving in place (for now) only ones where process_immext() is involved.
2019-07-01x86: optimize AND/OR with twice the same registerJan Beulich1-2/+2
It seems to be not uncommon for people to use AND or OR in this form for just setting the status flags. TEST, which doesn't write to any register other than EFLAGS, ought to be preferred. Make the change only for -O2 and above though, at least for now.
2019-07-01x86-64: optimize certain commutative VEX-encoded insnsJan Beulich1-167/+172
When they're in the 0F opcode space, swapping their source operands may allow switching from 3-byte to 2-byte VEX prefix encoding. Note that NaN behavior precludes us doing so for many packed and scalar floating point insns; such an optimization would need to be done by the compiler instead in this case, when it knows that NaN-s have undefined behavior anyway. While for explicitly specified AVX/AVX2 insns the optimization (for now at least) gets done only for -O2 and -Os, it is utilized by default in SSE2AVX mode, as there we're re-writing the programmer's specified insns anyway. Rather than introducing a new attribute flag, the change re-uses one which so far was meaningful only for EVEX-encoded insns.
2019-07-01x86: optimize EVEX packed integer logical instructionsJan Beulich1-4/+4
As long as there's no write mask as well as no broadcast, and as long as the scaled Disp8 wouldn't result in a shorter EVEX encoding, encode VPAND{D,Q}, VPANDN{D,Q}, VPOR{D,Q}, and VPXOR{D,Q} acting on only the lower 16 XMM/YMM registers using their VEX equivalents with -O1. Also take the opportunity and avoid looping twice over all operands when dealing with memory-with-displacement ones.
2019-07-01x86: add missing pseudo ops for VPCLMULQDQ ISA extensionJan Beulich1-0/+8
While the ISA extensions doc suggests them to be made available just like the SDM does for the PCLMULQDQ ISA extension, these weren't added when supposrt for the new extension was introduced. Also make sure the 64-bit non-AVX512 test actually tests VEX encodings, not EVEX ones.
2019-07-01x86: drop bogus Disp8MemShift attributesJan Beulich1-3/+3
In commit dc821c5f9a ("x86: replace Reg8, Reg16, Reg32, and Reg64") I apparently blindly copied the original register/memory templates into separate ones, in particular without removing the Disp8MemShift which are applicable to templates with memory operands only.
2019-06-25x86: fix (dis)assembly of certain SSE2 insns in 16-bit modeJan Beulich1-1/+1
MOVNTI was wrongly assembled with a 66h prefix. Add IgnoreSize to address this. It and the scalar to/from integer conversion insns also were also wrongly using Ev / Gv, leading to 16-bit register names being printed when 32-bit ones were meant. Clone the 32-bit SSE2 test to cover both assembler and disassembler.
2019-06-25x86-64: also optimize ANDQ with immediate fitting in 7 bitsJan Beulich1-1/+1
The same reasoning applies here as did/does for immediates fitting in 31 bits.

2018-11-06x86: adjust {,E}VEX.W handling for PEXTR* / PINSR*Jan Beulich1-9/+9
PEXTR{B,W} and PINSR{B,W}, just like for AVX512BW, are WIG, no matter that the SDM uses a nonstandard description of that fact. PEXTRD, even with EVEX.W set, ignores that bit outside of 64-bit mode, just like its AVX counterpart.
2018-11-06x86: adjust {,E}VEX.W handling outside of 64-bit modeJan Beulich1-16/+16
Many VEX-/EVEX-encoded instructions accessing GPRs become WIG outside of 64-bit mode. The respective templates should specify neither VexWIG nor VexW0, but instead the setting of the bit should be determined from - REX.W in 64-bit mode, - the setting established through -mvexwig= / -mevexwig= otherwise. This implies that the evex-wig2 testcase needs to go away, as being wrong altogether. A few test additions desirable here will only happen in later patches, as the disassembler needs adjustments first. Once again SSE2AVX templates are left alone, for it being unclear what the behavior there should be.
2018-11-06x86: fix various non-LIG templatesJan Beulich1-43/+53
Quite a few templates were marked LIG while really the insns aren't. Introduce descriptive shorthands once again, instead of continuing to use the less legible original forms.
2018-11-06x86: allow {store} to select alternative {,}PEXTRW encodingJan Beulich1-7/+6
The 0F C5 encoding is indeed a load type one (just that memory operands are not permitted), while the 0F 3A 15 encoding is obviously a store. Allow the pseudo prefixes to be used to select between them. Also move (without any change) the secondary AVX512BW templates next to the primary one.
2018-11-06x86: add more VexWIGJan Beulich1-143/+143
Commits 6865c0435a ("x86: Support VEX/EVEX WIG encoding") and 6fa52824c3 ("x86: Replace VexW=3 with VexWIG") omitted quite a few templates, oddly enough in some cases despite testcases getting added (which then were recorded with wrong expected output). Also adjust VPMAXUB's attributes in the AVX512BW case to match ordering of that of neighboring templates. For the moment SSE2AVX templates are left alone, as it isn't clear whether they were intentionally left untouched by the original commits (the descriptions don't say either way). In this context I question the decision in commit 0375113302 ("x86: Add -mvexwig=[0|1] option to assembler") to move the logic to determine the value of the W bit ahead of the decision whether to use 2-byte VEX: While I can see this as one possible interpretation of -mvexwig=, the other alternative (setting the value of the bit only if it actually exists in the encoding) looks as reasonable to me, and perhaps even more in line with us generally trying to pick the shortest encoding.
2018-11-06x86: XOP VPHADD* / VPHSUB* are VEX.W0Jan Beulich1-17/+19
Also avoid introducing further uses of VexW=1, by introducing and using VexW0 at this occasion. Move the marker past all #define-s.

Update assembler to check VEXWIG when setting the VEX.W bit. gas/ PR gas/23642 * config/tc-i386.c (build_vex_prefix): Check VEXWIG when setting the VEX.W bit. (build_evex_prefix): Check VEXWIG when setting the EVEX.W bit. opcodes/ PR gas/23642 * i386-opc.h (VEXWIG): New. * i386-opc.tbl: Set VexW=3 on VEX/EVEX WIG instructions. * i386-tbl.h: Regenerated.
2018-09-14x86: fold CRC32 templatesJan Beulich1-6/+2
Just like other insns having byte and word forms, these can also make use of the W modifier, which at the same time allows simplifying some other code a little bit.
2018-09-13x86: Remove VexW=1 from WIG VEX movq and vmovqH.J. Lu1-4/+4

2018-09-13i386: Update VexW field for VEX instructionsH.J. Lu1-18/+18
1. Mark VEX.W0 VEX instructions with VexW=1. 2. Mark VEX.W1 VEX instructions with VexW=2. 3. Remove VexW=1 from WIG VEX instructions. * i386-opc.tbl: Add VexW=1 to VEX.W0 VEX movd, cvtsi2ss, cvtsi2sd, pextrd, pinsrd, vcvtsi2sd, vcvtsi2ss, vmovd, vpextrd and vpinsrd. Add VexW=2 to VEX.W1 VEX movd, movq, pextrq, pinsrq, vmod, vmovq, vpextrq and vpinsrq. Remove VexW=1 from WIG VEX movq and vmovq. * i386-tbl.h: Regenerated.
