2023-07-11x86: misc further memory-only insns don't need to go through mod_table[]Jan Beulich1-2/+2
Several already use OP_M(), which rejects the register forms of insns, and a few others can easily be converted to do so as well. (Note that FXSAVE_Fixup() wires through to OP_M(). Note further that OP_IndirE(), which wasn't placed very well anyway, is moved down to avoid the need to forward-declare BadOp().) Also adjust formatting of and drop PREFIX_OPCODE from a few adjacent entries.
2023-07-04x86: flag bad EVEX masking for miscellaneous insnsJan Beulich1-2/+2
Masking is not permitted for certain further insns, not falling in any of the earlier categories. Introduce the Y macro (not expanding to any output) to flag such cases. Note that in a few cases entries already covered otherwise are converted as well, to continue to allow sharing of the string literals.
2022-10-24x86: emit {evex} prefix when disassembling ambiguous AVX512VL insnsJan Beulich1-6/+6
When no AVX512-specific functionality is in use, the disassembly of AVX512VL insns is indistinguishable from their AVX counterparts (if such exist). Emit the {evex} pseudo-prefix in such cases. Where applicable drop stray uses of PREFIX_OPCODE from table entries.
2021-03-10x86/Intel: correct AVX512 S/G disassemblyJan Beulich1-14/+4
Commit 6ff00b5e12e7 ("x86/Intel: correct permitted operand sizes for AVX512 scatter/gather") brought the assembler side of AVX512 S/G insn handling in line with AVX2's, but the disassembler side was forgotten. This has the benefit of - allowing to fold a number of table entries, - rendering a few #define-s and enumerators unused.
2021-03-10x86: re-arrange order of decode for various EVEX opcodesJan Beulich1-10/+20
The order of decodes influences the overall number of table entries. Reduce table size quite a bit by first decoding few-alternatives attributes common to all valid leaves. This also adds a PREFIX_DATA 7531c61332db ("x86: simplify decode of opcodes valid with (embedded) 66 prefix only") missed to apply to vbroadcastf64x4.
2020-07-14x86: simplify decode of opcodes valid with (embedded) 66 prefix onlyJan Beulich1-12/+12
The only valid (embedded or explicit) prefix being the data size one (which is a fairly common pattern), avoid going through prefix_table[]. Instead extend the "required prefix" logic to also handle PREFIX_DATA alone in a table entry, now used to identify this case. This requires moving the (adjusted) ->prefix_requirement logic ahead of the printing of stray prefixes, as the latter needs to observe the new setting of PREFIX_DATA in used_prefixes. Also add PREFIX_OPCODE on related entries when previously there was mistakenly no decode step through prefix_table[].
