Just looking for any documentation on target specific intrinsics, initially specifically the x86 sse intrinsics. Is there anything outside the source code that provides any documentation of such things -- I couldn't find anything definitive.
Many of the x86 intrinsics now have descriptions in the header files (clang/lib/Headers), that can be used to generate documentation. Many of the intrinsics also have documentation provided by other vendors (gcc, Intel) that is available on the web just by searching on the intrinsic function name. I know I’ve found things that way.
