2021-03-14alternate display mode for c-style expressionsiximeow
2021-01-15support xchg AX/reg0.1.5iximeow
2021-01-15fix several missing or invalid decodings among 0f01 opcodesiximeow
* `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
2020-11-19fix decoding of rex-prefixed modrm+sib operands selecting index 0b100 and ↵0.1.4iximeow
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.
2020-10-27fix misdecode of instructions in opcode 0x800.1.3iximeow
2020-08-15add register class constants to allow reasoning about register operands0.1.1iximeow
also bump to 0.1.1
2020-08-09adjust public interface: public items should all be stableiximeow
`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.

2020-05-23fix important memory decode error in long modeiximeow
add tests for modrm/sib decoding, xsave extensions
2020-05-23add SHA, BMI1, and BMI2, complete XSAVE extension supportiximeow
additionally: cmpcxchg{8,16}b, rdrand, rdseed, rdpid, {rd,wr}{fs,gs}base
2020-05-21add sha, lzcnt, tsx, f16c, svm, movbe, adx, and prefetchw extensionsiximeow
also add builders to get decoders appropriate for specific microarchitectures from intel and amd * low-power architectures are not yet present
2020-05-03add width() to ask width of an x86 operandiximeow
this is largely wrong for memory operands, which require more invasive changes
2020-05-03that instruction is cwd, not cbdiximeow
2020-05-03bump yaxpeax-arch to 0.0.4, use AddressDiff, fix warnings in ffiiximeow
2020-03-22yaxpeax-x86 decodes in 32-bit mode nowiximeow
2020-02-22remove unused functioniximeow
2020-02-22support most avx operand codesiximeow
avx is still incomplete, but less so avx is still practically untested
2020-02-22fix {jmp,call} <reg>, as well as jmpf/callfiximeow
also support vmxon to finish out the f30f opcode map add tests for forms of inc/dec, as well as TODOs, as yaxpeax-x86 doesn't provide a way to distinguish different operand sizes (yet)
2020-02-22more sse/sse2 supportiximeow
largely f20f/f30f opcode map items
2020-02-22add vmclear testiximeow
this instruction is decoded with the sse2 660f map but not actually added in sse2
2020-02-22support 660f sse2 instructionsiximeow
this isn't quite all of sse2, but gets close. the f20f opcode map still needs some touching up. also fix `G_E_xmm_Ib` not respecting rex.r for the rrr operand
2020-02-16embarassingly had OperandSpec variants for modrm displacement == 0 backwardsiximeow
