[LLVMdev] SIMD trigonometry/logarithms?
FWIW, llvmpipe has C-binding code that generates (inlines) log/exp/pow/sin/cos functions of the fly, for an arbitrary number of elements (in most cases), and uses sse/avx intrinsics as available: http://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/auxiliary/gallivm/lp_bld_arit.c The precision is 20bits, which is enough for 3D. But it wouldn't be difficult to have more (or even variable)

[LLVMdev] SIMD trigonometry/logarithms?
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)? Cheers, Dimitri. -------------- next part -------------- An HTML attachment was scrubbed... URL:
