From an architectural POV, I think @westonpace and @lidavidm would be the most apt at giving advice. I just have a couple questions: 1. are we talking about BMI or BMI2 here? Those are two different things. 2. do we have to call intrinsics explicitly? are the corresponding operations exposed by https://github.com/xtensor-stack/xsimd and, if not, can we perhaps contribute them? 3. perhaps some compiler optimizers can even produce those instructions automatically given the right code patterns? Also cc @cyb70289 for more expert SIMD advice. -- This is an automated message from the Apache Git Service.
