2019-11-12x86: fold EsSeg into IsStringJan Beulich1-4/+1
EsSeg (a per-operand bit) is used with IsString (a per-insn attribute) only. Extend the attribute to 2 bits, thus allowing to encode - not a string insn, - string insn with neither operand requiring use of %es:, - string insn with 1st operand requiring use of %es:, - string insn with 2nd operand requiring use of %es:, which covers all possible cases, allowing to drop EsSeg. The (transient) need to comment out the OTUnused #define did uncover an oversight in the earlier OTMax -> OTNum conversion, which is being taken care of here.
2019-11-12x86: eliminate ImmExt abuseJan Beulich1-0/+1
Drop the remaining instances left in place by commit c3949f432f ("x86: limit ImmExt abuse), now that we have a way to specify specific GPRs. Take the opportunity and also introduce proper 16-bit forms of applicable SVME insns as well as 1-operand forms of CLZERO.
2019-11-12x86: introduce operand type "instance"Jan Beulich1-17/+42
Special register "class" instances can't be combined with one another (neither in templates nor in register entries), and hence it is not a good use of resources (memory as well as execution time) to represent them as individual bits of a bit field. Furthermore the generalization becoming possible will allow improvements to the handling of insns accepting only individual registers as their operands.
2019-11-08x86: convert RegMask and RegBND from bitfield to enumeratorJan Beulich1-5/+5
This is to further shrink the operand type representation.
2019-11-08x86: convert RegSIMD and RegMMX from bitfield to enumeratorJan Beulich1-6/+6
This is to further shrink the operand type representation.
2019-11-08x86: convert Control/Debug/Test from bitfield to enumeratorJan Beulich1-6/+6
This is to further shrink the operand type representation.
2019-11-08x86: convert SReg from bitfield to enumeratorJan Beulich1-2/+2
This is to further shrink the operand type representation.
2019-11-08x86: introduce operand type "class"Jan Beulich1-13/+42
Many operand types, in particular the various kinds of registers, can't be combined with one another (neither in templates nor in register entries), and hence it is not a good use of resources (memory as well as execution time) to represent them as individual bits of a bit field.
2019-11-07x86: support further AMD Zen2 instructionsJan Beulich1-1/+7
Both RDPRU and MCOMMIT have been publicly documented meanwhile: https://www.amd.com/system/files/TechDocs/24594.pdf.
2019-10-30x86: re-do "shorthand" handlingJan Beulich1-42/+13
Now that the opcode table gets preprocessed, undo parts of commit dc821c5f9a ("x86: replace Reg8, Reg16, Reg32, and Reg64"): Have the preprocessor handle the expansion there, while making the expansions explicit in i386-gen and the register table.
2019-10-30x86: slightly rearrange struct insn_templateJan Beulich1-2/+1
This avoids holes between the individual fields, (potentially) shrinking the overall template table size by 4 bytes per entry.
2019-10-30x86: drop stray WJan Beulich1-0/+24
The flag is used to indicate opcodes which can be switched between byte and word/dword/qword forms (in a "canonical" way). Obviously it's quite odd then to see it on insns not allowing for byte operands in the first place. As a result the opcode bytes need to be adjusted accordingly, which includes comparisons done in optimize_encoding(). To make re-introduction of such issues less likely have i386-gen diagnose it (in a generally non-fatal way for now).
2019-07-17x86: drop stale Mem enumeratorJan Beulich1-1/+15
This was supposed to also be removed by c48dadc9a8 ('x86: drop "mem" operand type attribute'). It's odd enough that this hasn't caused build issues, considering the careful use of OTunused (apparently to avoid "missing initializer" warnings). To avoid such happening again introduce compile time consistency checks.
2019-07-16x86: make RegMem an opcode modifierJan Beulich1-1/+1
... 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 Beulich1-6/+3
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 Beulich1-3/+0
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).
2019-06-25x86: correct / adjust debug printingJan Beulich1-5/+7
For quite some time we've been using combinations of bits for specifying various registers in operands and templates. I think it was Alan who had indicated that likely the debug printing would need adjustment as a result. Here we go. Accumulator handling for GPRs gets changed to match that for FPU regs. For this to work, OPERAND_TYPE_ACC{32,64} get repurposed, with their original uses replaced by direct checks of the two bits of interest, which is cheaper than operand_type_equal() invocations. For SIMD registers nothing similar appears to be needed, as respective operands get stripped from the (copy of the) template before pt() is reached. The type change on pi() is to silence a compiler diagnostic. Arguably its other parameter could also be const-qualified.

Instead of expanding macro-like constructs in i386-gen, have the C pre- processor do this for us. Besides being a prerequisite for the next template folding steps, this also paves the way for removing various hidden dependencies between #define-s in i386-opc.h and plain literal numbers used in i386-opc.tbl. The #undef of None is solely to leave the generated i386-tbl.h entirely unchanged.

2018-04-26x86: CpuXSAVE is a prereq for various other featuresJan Beulich1-7/+7
All of AVX, LWP, MPX, and PKU require XSAVE, and hence it as well as XRSTOR should be enabled when enabling these ISA extensions. Leverage these implications to shorten some of the cpu_flag_init[] entries.

It's not clear to me why they had been introduced - the respective comments in opcodes/i386-gen.c are certainly wrong: ymm<N> registers are very well supported (and necessary) with just AVX512F.
2018-04-26x86: x87-related adjustmentsJan Beulich1-3/+3
Neither 287 wrt 8087 nor 387 wrt 287 are proper supersets - in each case some insns get removed from the ISA (they become NOPs, but code intended for newer co-processors should not use them). Furthermore with .no87, ST should not be recognized as a register name.

It again can be inferred from other information. The vpopcntd templates all need to have Dword added to their memory operands; the lack thereof was actually a bug preventing certain Intel syntax code to assemble, so test cases get extended.

2018-02-27x86: Add -O[2|s] assembler command-line optionsH.J. Lu1-0/+1
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. gas/ PR gas/22871 * NEWS: Mention -O[2|s]. * config/tc-i386.c (_i386_insn): Add no_optimize.
