This was the clue I needed, SSE4.1 intrinsics die because llvm doesn't think they're legal for the target, because llvm 3.6 doesn't know about broadwell or skylake so they just appear as generic. Adding their model numbers to the Haswell path seems to do the trick (since apparently Haswell Pentium has the same property re AVX). - ajax _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
