| 2023-01-02 | yax builds again with opcodes generated by type | iximeow | |
| 2022-12-03 | fix incorrect rex selection and field description offsets | iximeow | |
| 2022-12-03 | 66 prefixes are common, 0f opcodes are common | iximeow | |
| 2022-12-03 | support a fast path through the decoder for [rex-prefixed]opcode insts | iximeow | |
| the overwhelming majority of x86 instructions are either a single-byte opcode or a single-byte opcode with a rex prefix. supporting these specially means that we don't have to length-check on every byte or go through the full decode loop while reading the most likely instructions. this is a significant improvement on typical x86 streams, but comes at a moderate penalty for crafted x86 instructions. the penalty is still not very bad, as the fast path is exited in favor of the full decode loop as soon as we see a non-rex prefix byte; this adds maybe a dozen instructions to the slow path. | |||
| 2022-12-03 | just a bit more code motion that seemed to help things sometimes | iximeow | |
| 2022-12-03 | reorder prefix checks, extract vex/evex prefix handling | iximeow | |
| sharing vex/evex invalid prefix checks improves codegen a bit, but ordering prefix checks by likeliest prefix first reduces time falling through prefix handling arms. both together are a notable improvement in throughput on typical x86 code. bundled in here is some code motion to where `mem_size = 0` and `operand_count = 2` are executed; this is because, at least on zen2 and cascade lake parts, bunching all stores to the instruction together caused small stalls getting into the decoder. spreading out stores seems to mix these assignments with parts of code that was not using memory anyway, and pipelines better. | |||
| 2022-12-03 | move opcode lookup tables into const arrays | iximeow | |
| cleanliness, but also slightly better codegen somehow? | |||
| 2022-12-03 | replace size lookup logic with a LUT | iximeow | |
| the match compiled into some indirect branch awfulness!! no thank you | |||
| 2022-09-23 | Fix some typos. | Bruce Mitchener | |
| 2022-05-07 | more annotation fixes? | iximeow | |
| 2022-04-24 | fix a few issues preventing no-std builds from ... building | iximeow | |
| this includes a `Makefile` that exercises the various crate configs. most annoyingly, several doc comments needed to grow `#[cfg(feature="fmt")]` blocks so docs continue to build with that feature enabled or disabled. carved out a way to run exhaustive tests; they should be written as `#[ignore]`, and then the makefile will run even ignored tests on the expectation that this will run the exhaustive (but slower) suite. exhaustive tests are not yet written. they'll probably involve spanning 4 byte sequences from 0 to 2^32-1. | |||
| 2022-01-02 | Wrap unsafe functions to catch errors in debug | 5225225 | |
| Closes https://github.com/iximeow/yaxpeax-x86/issues/16 | |||
| 2021-12-19 | fix incorrect memory size for f30f1e-style nop | iximeow | |
| not only did the instruction have wrong data, but if displayed, the formatter would panic. | |||
| 2021-12-19 | test that invalid RegSpec constructions panic as expected | iximeow | |
| in the process, fix 64-bit rex-byte limit, 32/16-bit mode mask reg limit | |||
| 2021-10-10 | support endbr{32,64} | iximeow | |
| 2021-10-10 | export `InstructionDisplayer` (#9) | i509VCB | |
| This makes generated docs refer to a type and show said type in the list of all structs rather than rustdoc showing gray text in return types. quote doc references | |||
| 2021-08-22 | bump to yaxpeax-arch 0.2.7 and proper field description support1.1.0 | iximeow | |
| 2021-08-22 | add 16/32-bit opcode/operand boundary desc, consistentify memory descriptions | iximeow | |
| 2021-08-21 | add `AnnotatingDecoder` note to CHANGELOG and publicize descriptions | iximeow | |
| 2021-08-21 | maintain pre-annotation inlining properties | iximeow | |
| this gets yaxpeax-x86 in no-inline configurations back to building as it did before, but is quite a blunt hammer. it seems that extra calls to `sink.record` trips the inlining thresholds for `read_with_annotation`, and then its caller, and its caller, even when one of them is just a delegation to its inner call. this is particularly unfortunate because yaxpeax-x86 is now making a decision about the inlining of a rather large function at the public edge of its API, but these attributes match the inlining decisions that LLVM was making before adding `DescriptionSink`. hopefully not too bad. not sure how to handle this in the future. | |||
| 2021-08-21 | add descriptions for other prefixes, 16-bit addressing | iximeow | |
| 2021-08-21 | add description reporting for segment prefixes and opcodes for 32-bit and 16-bit | iximeow | |
| 2021-08-21 | extend decoder annotation through all of 64-, 32-, and 16-bit modes | iximeow | |
| 2021-08-21 | force read_sib inlining in 64-bit mode | iximeow | |
| even though NullSink is no-ops, it causes llvm to not inline this function, for a net perf reduction | |||
| 2021-08-21 | extend annotation reporting to 32- and 16-bit modes, kinda | iximeow | |
| 2021-08-21 | wip | iximeow | |
| 2021-08-21 | fix incorrect decoding of 0x9*-series instructions with rex.b | iximeow | |
| 2021-08-21 | report memory sizes for push, pop, call, ret | iximeow | |
| these instructions had memory sizes reported for the operand, if it was a memory operand, but for versions with non-memory operands the decoded `Instruction` would imply that non memory access would happen at all. now, decoded instructions in these cases will report a more useful memory size. | |||
