2019-07-01Document the .value directive supported by the x86 and x86_64 assemblers.Nick Clifton1-0/+6
PR 24738 * doc/c-i386.texi (i386-Directives): Add a description of the Value directive.
2019-07-01x86: optimize AND/OR with twice the same registerJan Beulich1-1/+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 Beulich1-1/+4
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 Beulich1-6/+10
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.

2019-06-25x86: document certain command line options as "dangerous"Jan Beulich1-0/+6
Errata BT36, BT41, and BT230 mean that gas may, when using one ofthese options, produce code that causes #UD on (at least) SandyBridge systems.

2018-07-02Fix use of "command line X" in binutils docThomas Preud'homme1-1/+1
Binutils documentation uses a mix of spelling for the compound word "command-line X". According to [1]: "Sometimes compound words are written separately (nail polish), sometimes with a hyphen (short-sighted) and sometimes as one word (eyelashes). Often new compounds are written as two separate words and, as they become more familiar, they are either connected with a hyphen (-) or made into one word." I think command-line X is common enough in our industry that the two workds command and line should be connected. Since command-line is more common than commandline, I propose to update binutils documentation to consistently use "command-line" when this is used as an adjective to a noun (eg. command-line argument, command-line switch, command-line option and command-line flag). I've left occurences of "the command line" as is. I've also left gdb, sim and readline alone and have only touched public documentation (texi and NEWS files).

2018-02-27x86: Add -O[2|s] assembler command-line optionsH.J. Lu1-0/+25
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.

2017-03-09X86: Add pseudo prefixes to control encodingH.J. Lu1-4/+24
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}.
