...in our code so any performance gain would be useful. However, accuracy is quite important in our case, so we would want any implementation to at least match the accuracy of the current implementation. On X86 (at least in LLVM 2.8 which we currently use), the sin/cos intrinsics end up using the X87 fpsin instruction. On Win32, the system provided sin function also ends up using the same assembly instruction. Peter N

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)?
