Hi everyone, I was looking at loop vectorizer code and wondered if there was any current or planned effort to introduce SIMD implementations of sin/cos/exp/log intrinsics (in particular for x86-64 backend)?

We use math functions a lot in our code so any performance gain would be useful. However, accuracy...
