--- Comment #5 from Patrick J. LoPresti <lopre...@gmail.com> --- Just a thought... How about adding VEX opcodes corresponding to these string instructions? Although the behavior of these instructions is (ludicrously) complex, the data flow is pretty simple: Two vectors of input; one vector and a few condition codes of output; every byte past the first zero ignored. It seems to me that it should be pretty straightforward to do the memcheck instrumentation directly for most (all?) of the PCMPxSTRx variants. Intel has had a few instruction set iterations (AVX2/AVX512/BMI/etc.) and they have not added any more monstrosities like these, so I do not think this would be entering an endless rat hole. What do you think? -- You are receiving this mail because: You are watching all bug changes.
