X86 SSE Intrinsics

Hi,

I need some documentation on how to use the LLVM X86 intrinsics for SSE support -like “x86_sse2_movnt_dq/x86_ssse3_pshuf_b/…” How to use them as functions in the code, and what are the correct argument types / return value types for each?

Could anybody point me to where I can find this documentation?

Thanks,
