2024-07-04Support APX CFCMOVCui, Lili1-1968/+1998
The CMOVcc instruction proposed by EVEX has four different forms, corresponding to the four possible combinations of EVEX.ND and EVEX.NF values. In the encoder part, when the CFCMOV template supports EVEX_NF, it means that it requires EVEX.NF to be 1. In the decoder part, CFCMOV_Fixup is used to reverse source and destination operands in the 2-operand case. gas/ChangeLog: * config/tc-i386.c (build_apx_evex_prefix): Set NF bit for cfcmov when the insn template supports EVEX_NF. * testsuite/gas/i386/x86-64-apx-inval.l: Add invalid tests for cfcmov. * testsuite/gas/i386/x86-64-apx-inval.s: Ditto. * testsuite/gas/i386/x86-64.exp: Add tests for cfcmov and cmov. * testsuite/gas/i386/x86-64-apx-cfcmov-intel.d: Ditto. * testsuite/gas/i386/x86-64-apx-cfcmov.d: Ditto. * testsuite/gas/i386/x86-64-apx-cfcmov.s: Ditto. opcodes/ChangeLog: * i386-dis-evex-prefix.h: Add cfcmov instructions. * i386-dis.c (CFCMOV_Fixup): Special handling of cfcmov.

2024-06-18Support APX CCMP and CTESTCui, Lili1-1918/+1974
CCMP and CTEST are two new sets of instructions for conditional CMP and TEST, SCC and OSZC flags are given as suffixes of CCMP or CTEST in the instruction mnemonic, e.g.: ccmp<cc> { dfv=sf , cf , of } %eax, %ecx also add {evex} cmp/test %eax, %ecx as an alias for ccmpt. For the encoder part, add function check_Scc_OszcOperation to parse '{ dfv=of , sf, sf, cf}', store scc in the lower 4 bits of base_opcode, and adjust base_opcode to its normal meaning in install_template. For the decoder part, add 'SC' and 'DF' macros to add scc and oszc flags suffixes. gas/ChangeLog: * config/tc-i386.c (OSZC_CF): New. (OSZC_ZF): Ditto. (OSZC_SF): Ditto. (OSZC_OF): Ditto.

2023-03-31x86: introduce .insn directiveJan Beulich1-0/+1
For starters this deals with only very basic constructs.
2023-01-20x86: re-use insn mnemonic strings as much as possibleJan Beulich1-2319/+2319
Compact the mnemonic string table such that the tails of longer mnemonics are re-used for shorter ones, going beyond what compilers would typically do, but matching what ELF linkers may do when processing SHF_MERGE|SHF_STRINGS sections. This reduces table size by about 12.5%.
2023-01-20x86: move insn mnemonics to a separate tableJan Beulich1-0/+2341
Using full pointers to reference the insn mnemonic strings is not very efficient. With overall string size presently just slightly over 20k, even a 16-bit value would suffice. Use "unsigned int" for now, as there's no good use we could presently make of the otherwise saved 16 bits. For 64-bit builds this reduces table size by 6.25% (prior to the recent ISA extension additions it would have been 12.5%), with a similar effect on cache occupation of table entries accessed. For PIE builds of gas this also reduces the number of base relocations quite a bit (obviously independent of bitness).
