[llvm-dev] RFC: SIMD math-function library

[Naoki Shibata via llvm-dev]

Thank you. And now I understand why it is not very easy to port SVML to 
other architectures.

But,  Intel SVML is x86 centric (SSE2, SSSE3, SSE4.1, SSE4.2, AVX, AVX2 ....}. Personally, I am not sure if it would be fairly easy to port SVML to other architectures. SVML library team may provide a better answer, I will double check with them.
