2023-12-16fix incorrect register selection for `vpmovm2*` with `rex.b` setiximeow
2023-12-16abnormal memory sizes for keylocker instructions are not bugsiximeow
new `does_not_decode_invalid_registers` fuzzer found other bugs! the 384-bit accesses for 128b keylocker instructions are an otherwise-unknown size and had a memory size of `BUG`. they are not bugs. give the memory size a real name.
2023-12-15more RegSpec constructor validation, fix bug in x86_64 1b reg specsiximeow
* the first four 1-byte registers, `al`, `cl`, `dl`, `bl`, can be constructed in two ways that produce "identical" `RegSpec` that are.. not. e.g. `RegSpec::al() != Regspec::rb(0)` even though `RegSpec::al().name() == RegSpec::rb(0).name()`. this corrects the `rb` constructor at least, but instructions like `4830c0` and `30c0` still produce incompatible versions of `al`. * also fix register numbering used explicit qword-sized RegSpec constructors, r12 and r13 used to produce r8 and r9
2023-07-24fix handling of lar/lsl source registeriximeow
2023-07-23fix inconsistently-poreted memory access size of vcvt{,t}{sd,si}iximeow

2023-03-05add `Opcode::is_jcc`, `Opcode::is_setcc`, and `Opcode::is_cmovcc` helpersiximeow
this request/suggestion comes from [github](https://github.com/iximeow/yaxpeax-x86/issues/29)! thank you!
2022-04-30support 0x9a callf in 16/32-bit modesiximeow
2022-04-24fix a few issues preventing no-std builds from ... buildingiximeow
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.
2021-12-19fix incorrect memory size for f30f1e-style nopiximeow
not only did the instruction have wrong data, but if displayed, the formatter would panic.
2021-12-19test that invalid RegSpec constructions panic as expectediximeow
in the process, fix 64-bit rex-byte limit, 32/16-bit mode mask reg limit
2021-12-17do not panic on negative compressed displacements, i mean it!!iximeow
2021-12-16displacements are stored as unsigned, but are functionally signed intsiximeow
so multiplying to expand EVEX compressed offsets can overflow, and that needs to be okay.
2021-10-10support endbr{32,64}iximeow
2021-08-21fix negative relative branches (again!!! +- is bad!!!)iximeow
2021-08-21report memory sizes for push, pop, call, retiximeow
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.
2021-08-14relative branches should be shown as $+offset, not just plain offsetiximeow
while x86 branches of immediates are all relative to PC, other architectures may have absolute branches to immediate addresses, leaving this syntax ambiguous and potentially confusing. yaxpeax prefers to write relative offsets `$+...` as a rule, so uphold that here.
