...bit weird to do that per instruction, but d3d11 does that as well. (Some d3d versions just have a global flag basically forbidding or allowing any such fast math optimizations in the assembly, but I'm not actually sure everybody honors that without tesselation...) For 1/9: Reviewed-by: Roland Scheidegger <sroland at vmware.com> 2/9 has a typo in the commit short log ("Instrutions").

Hi, hit by a bug in llvm 2.8, I was wondering if there are any stable release branches? The bug is only present in the release branch, and I have a fix for it (see attachment). IMHO the bug is quite bad, and workarounds are actually ugly and generate inefficient code (couldn't really come up with anything which actually generated correct code which didn't require at least a pshufb).
