WebConfigure. Ideally, set march=native in pragma but this does not work. Use instruction targets for "haswell" or "core-avx2". The bare minimum: #pragma GCC optimize ("O3,inline") #pragma GCC target ("bmi,bmi2,lzcnt,popcnt") I would personally recommend adding SIMD as well. The compiler can use it even if you don't code the instructions yourself: Web8 sept. 2024 · ICC and MSVC preserve `isnan` in fast-math mode. ...
