| 13 hours | actually support avx/f16c in per-uarch decoding | iximeow | |
| 13 hours | vmaskmovdqu, vmovq were also incorrect in some ways... | iximeow | |
| 13 hours | more general avx improvements | iximeow | |
| 13 hours | cleanup pass on vex-encoded instructions is going to be exciting | iximeow | |
| 13 hours | report memory access size for "monitor" | iximeow | |
| 13 hours | maskmov{q,dqu} memory access size | iximeow | |
| 13 hours | more precise about 0f0d prefetch/nop | iximeow | |
| 13 hours | fix table management instructions' ({l,s}{g,i,l}dt) mem_size | iximeow | |
| these instructions, it turns out, have fixed operand size based on CPU execution mode and regardless of prefixes. good to know! | |||
| 13 hours | push/pop for segment registers has implicit memory access | iximeow | |
| 13 hours | pushf, popf, enter, leave, xlat all have implicit memory access | iximeow | |
| also add "is_masked" to operand spec | |||
| 13 hours | add initial stats for disasm stats in all modes | iximeow | |
| 2026-02-14 | fair enough on those warnings | iximeow | |
| 2026-02-14 | type aliases make some of these signatures less egregious.. | iximeow | |
| 2025-06-01 | 3dnow was still supported on K8, K10. 32-bit mode should learn about uarch ↵ | iximeow | |
| tweaks too | |||
| 2025-06-01 | describe the per-isa extensions a bit better | iximeow | |
| 2025-06-01 | revise_instruction is the same on all bitnesses, so macro it too | iximeow | |
| 2025-06-01 | DecodeEverything wasn't useful, no better than InstDecoder::default()?? | iximeow | |
| 2025-06-01 | cpu feature bits are the same across 64/32/16-bit | iximeow | |
| 2025-06-01 | expand isa feature selection to more bits | iximeow | |
| this is backed by the new IsaSettings trait. the existing InstDecoders are unchanged, except that they implement this new trait. also add new `DecodeEverything` structs with `IsaSettings` impls that are unconditionally set to permit anything the decoder can be configured to conditionally accept or reject. in the process, add new `_3dnow` flag and stop accepting 3dnow instructions in uarch-specific decoder settings that would not have 3dnow instructions. update AMD microarchitectures and cross-ref chip directory | |||

| 2024-06-23 | add more conditional inlining for 32-bit and 16-bit decoders | iximeow | |
| 2024-04-02 | display opt: mem size labels and minor segment reporting changes | iximeow | |
| for mem size labels: add one new "BUG" entry at the start of the array so `mem_size` does not need to be adjusted before being used to look up a string from the `MEM_SIZE_STRINGS` array. it's hard to measure the direct benefit of this, but it shrinks codegen size by a bit and simplfies a bit of assembly.... for segment reporting changes: stos/scas/lods do not actually need special segment override logic. instead, set their use of `es` when decoded, if appropriate. this is potentially ambiguous; in non-64bit modes the sequence `26aa` would decode as `stos` with explicit `es` prefix. this is now identical to simply decoding `aa`, which now also reports that there is an explicit `es` prefix even though there is no prefix on tne instruction. on the other hand, the prefix-reported segment now more accurately describes the memory selector through which memory accesses will happen. seems ok? | |||
| 2023-12-16 | fix hreset being disassembled as having second operand of "Nothing" | iximeow | |
| just report it having one operand... | |||

| 2023-03-05 | add `Opcode::is_jcc`, `Opcode::is_setcc`, and `Opcode::is_cmovcc` helpers | iximeow | |
| this request/suggestion comes from [github](https://github.com/iximeow/yaxpeax-x86/issues/29)! thank you! | |||
| 2023-02-19 | deprecate `pub fn cs`, which is an intensely embarrassing bug of a function | iximeow | |
| unlike every other function to test if a particular selector is picked by prefixes, `Prefixes::cs` does not return bool, nor does it check the currently-selected prefix. instead, it modifies the decoded `Prefixes` to set the current prefix to `cs`. this has been a bug all the way since 0.0.1 was released. the function now does nothing, and is marked deprecated. in a future 2.x release, the function will be changed to return `bool` and be in-line with other segment selector-checking functions. in the mean time, a new `Prefixes::selects_cs()` does the correct thing. thank you to @meithecatte who pointed this out in https://github.com/iximeow/yaxpeax-x86/issues/28! | |||
| 2022-12-03 | roll up decoding loop changes for 16-bit and 32-bit decoders | iximeow | |
| this applies * f338c74656f6eef8b3080fa9f249b1cb733fd1a9 * bece19e6a69b158893abbf56a6cac25eb25d9a32 * 6353f58170d28a142e3b012c2c86f684d50dea45 * 67be1c0983244645a3c762b7aa0601f0d0ba4bb3 * 091f1d66ef853d6339a96e43d71c137ee7d3907a as one unit to both the 16-bit and 32-bit decoders. | |||
