| 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 | |
| 2021-03-14 | alternate display mode for c-style expressions | iximeow | |
| 2021-03-13 | split ffi crate to support distinct 16, 32, and 64-bit builds | iximeow | |
| initial work to optionally discard any instruction printing support when using `-Z build-std` to fully remove .eh_frame, a stripped long_mode_no_fmt .so is 61kb! | |||
| 2021-01-15 | support xchg AX/reg0.1.5 | iximeow | |
| 2021-01-15 | small perf tweaks | iximeow | |
| clearing reg_rrr and reg_mmm more efficiently is an extremely small win, but a win read_imm_signed generally should inline well and runs afoul of some heuristic. inlining gets about 8% improved throughput on the (unrealistic) in-repo benchmark it would be great to be able to avoid bounds checks somehow; it looks like they alone are another ~10% of decode time. i'm not sure how to pull that off while retaining the generic iterator parameter. might just not be possible. | |||
| 2021-01-15 | bump yaxpeax-x86 version for release | iximeow | |
| 2021-01-15 | fix several missing or invalid decodings among 0f01 opcodes | iximeow | |
| * `mwaitx`, `monitorx`, `rdpru`, and `clzero` are now supported * swapgs is no longer decoded in protected mode * rdpkru and wrpkru are no longer decoded if mod bits != 11 | |||
| 2020-11-19 | fix decoding of rex-prefixed modrm+sib operands selecting index 0b100 and ↵0.1.4 | iximeow | |
| base 0b101 for memory operands with a base, index, and displacement either the wrong base would be selected (register number ignored, so only `*ax` or `r8*` would be reported), or yaxpeax-x86 would report a base register is present when it is not (`RegIndexBaseScaleDisp` when the operand is actually `RegScaleDisp`) thank you to Evan Johnson for catching and reporting this bug! also bump crate version to 0.1.4 as this will be immediately tagged and released. | |||
| 2020-10-27 | Update README.md (#5) | Jan | |
| * Update README.md very typpo | |||
| 2020-10-27 | fix misdecode of instructions in opcode 0x800.1.3 | iximeow | |
| 2020-08-15 | add RegSpec constructors, consts, and const fns0.1.2 | iximeow | |
| 2020-08-15 | forgot to strengthen that heading too | iximeow | |
| 2020-08-15 | add register class constants to allow reasoning about register operands0.1.1 | iximeow | |
| also bump to 0.1.1 | |||
| 2020-08-09 | inaugural 0.1.0 release!0.1.0 | iximeow | |
| add doc comments for public items, record changelog, and lets ship this!! | |||
| 2020-08-09 | adjust public interface: public items should all be stable | iximeow | |
| `OperandCode` (obviously) wildly varies depending on how i feel on a given week, so it's now hidden to avoid people depending on numerical values of its discriminants. `RegisterBank` got a similar treatment with a new `RegisterClass` struct that's suitable for public use. | |||
