> Hmm, do we use BMI2 instructions in AVX2-optimized routines? That seems wrong. @westonpace @felipecrv The use of `_pext_u32` in `key_map_vx2.cc` dates back to 2021. Given that both AVX2 and BMI2 were introduced at the same time (Haswell), would it be a problem to also enable BMI2 when we enable AVX2 in the build? -- This is an automated message from the Apache Git Service.
