2018-10-10x86: fold Size{16,32,64} template attributesJan Beulich1-6/+5
Only one of them can be set at a time, which means they can be expressed by a single 2-bit field instead of three 1-bit ones.
2018-09-14x86: Support VEX/EVEX WIG encodingH.J. Lu1-0/+2
Add VEXWIG, defined as 3, to indicate that the VEX.W/EVEX.W bit is ignored by such VEX/EVEX instructions, aka WIG instructions. Set VexW=3 on VEX/EVEX WIG instructions.

2018-09-13x86: use D attribute also for SIMD templatesJan Beulich1-0/+2
Various moves come in load and store forms, and just like on the GPR and FPU sides there would better be only one pattern. In some cases this is not feasible because the opcodes are too different, but quite a few cases follow a similar standard scheme. Introduce Opcode_SIMD_FloatD and Opcode_SIMD_IntD, generalize handling in operand_size_match() (reverse operand handling there simply needs to match "straight" operand one), and fix a long standing, but so far only latent bug with when to zap found_reverse_match. Also once again drop IgnoreSize where pointlessly applied to templates touched anyway as well as *word when redundant with Reg*.
2018-08-11x86: Add CpuCMOV and CpuFXSRH.J. Lu1-0/+6

2018-08-06x86: fold RegEip/RegRip and RegEiz/RegRizJan Beulich1-4/+2
This allows to simplify the code in a number of places.
2018-08-03x86: drop "mem" operand type attributeJan Beulich1-1/+0
No template specifies this bit, so there's no point recording it in the templates. Use a flags[] bit instead.
2018-07-31x86: fold various AVX512 templates with so far differing Masking attributesJan Beulich1-2/+2
There's no insn allowing ZEROING_MASKING alone. Re-purpose its value for handling the not uncommon case of insns allowing either form of masking with register operands, but only merging masking with a memory operand.
2018-07-31x86: drop CpuVREXJan Beulich1-3/+0
It is fully redundant with CpuAVX512F.

2018-07-11x86: replace off-by-one OTMaxJan Beulich1-4/+4

2018-03-08x86: fold several AVX512VL templatesJan Beulich1-0/+2
The differences between some of the register and memory forms of the same insn often don't really require the templates to be separate. For example, Disp8MemShift is simply irrelevant to register forms. Fold these as far as possible, and also fold register-only forms. Further folding is possible, but needs other prereq work done first. A note regarding EVEXDYN: This is intended to be used only when no other properties of the template would make is_evex_encoding() return true. In all "normal" cases I think it is preferable to omit this indicator, to keep the table half way readable.
2018-03-08x86: drop FloatDJan Beulich1-3/+0
It can be expressed by D, when making the consumer look at operand size to tell apart both uses.
2018-02-27x86: Add -O[2|s] assembler command-line optionsH.J. Lu1-0/+4
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.

2017-12-18x86: fold certain AVX and AVX2 templatesJan Beulich1-1/+1
Just like for instructions in GPRs, there's no need to have separate templates for otherwise identical insns acting on XMM or YMM registers (or memory of the same size).
2017-12-18x86: fold RegXMM/RegYMM/RegZMM into RegSIMDJan Beulich1-13/+4
... qualified by their respective sizes, allowing to drop FirstXmm0 at the same time.

2017-12-18x86: replace Reg8, Reg16, Reg32, and Reg64Jan Beulich1-12/+3
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.
2017-11-30x86: drop Vec_Disp8Jan Beulich1-4/+0
This is fully redundant with Disp8MemShift being non-zero, and hence can be folded with normal Disp8 handling.

2017-03-09X86: Add pseudo prefixes to control encodingH.J. Lu1-4/+3
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. gas/ * config/tc-i386.c (_i386_insn): Add dir_encoding and vec_encoding. Remove swap_operand and need_vrex. (extra_symbol_chars): Add '}'. (md_begin): Mark '}' with LEX_BEGIN_NAME. Allow '}' in mnemonic. (build_vex_prefix): Don't use 2-byte VEX encoding with {vex3}. Check dir_encoding and load. (parse_insn): Check pseudo prefixes. Set dir_encoding. (VEX_check_operands): Likewise. (match_template): Check dir_encoding and load.
