| 2021-07-01 | reorder prefix checks | iximeow | |
| this measures a bit faster. it doesn't seem like it should be. the rex prefix checks compile identically but move a lea for a later expression up and pipelines better? | |||
| 2021-07-01 | reallocate OperandCode, convert disparate registers to array | iximeow | |
| also remove redundant assignments of operand_count and some OperandSpec, bulk-assign all registers and operands on entry to `read_instr`. this all, taken together, shaves off about 7 cycles per decode. | |||

| 2021-03-22 | port long-mode decoder updates to protected-mode | iximeow | |
| 2021-03-21 | update protected mode tests (this breaks them horribly. next commit will fix.) | iximeow | |
| 2021-03-21 | remove some forgotten println comments | iximeow | |
| 2021-03-21 | include memory sizes on inc/dec in C format | iximeow | |
| 2021-03-21 | make Opcode, Operand, and DecodeError non_exhaustive | iximeow | |
| in the future these can and will change (new operands, new instructions) and i would prefer they not be major breaking changes. applications can ignore them and probably do undesired variants anyway. if you want to write a 1120-variant match, are you me? why would you do this | |||
| 2021-03-21 | in real programs, having read_operands inlined hurts performance! | iximeow | |
| the in-repo benchmark got better with this inlined but it's probably better to leave it up to the compiler when finally stitching stuff together. i suspect that having read_operands inlined resulted in just too many live values, and the compiler was inspired to play hijinks that pipelined poorly. disas-bench shows a ~15% improvement from this change. | |||
| 2021-03-21 | fuzzing shows resetting operands is not beneficial | iximeow | |

| 2021-03-21 | rewrite 0f-based instruction handling | iximeow | |
| this is... a more significant rewrite than i expected yaxpeax-x86 to ever need. it turns out that capstone is extremely permissive about duplicative 66/f2/f3 prefixes to the point that the implemented prefex handling was unsalvageable. while this replaces the *0f* opcode tables, i haven't profiled these changes. it's possible this is a net improvement for single-byte opcodes, it could be a net loss. code size may be severely impacted. there is still work to do. but this in total gets very close to iced/xed/zydis parity, far more than before. also adds several small extensions, gfni, 3dnow, enqcmd, invpcid, some of cet, and a few missing avx instructions. | |||
| 2021-03-17 | support several new extensions, 3dnow, and nuance in invalid operands | iximeow | |
