Subject: Add AVX2 intrinsics for pavg, pblend, and pcmp instructions. Also remove unneeded... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4c07c5dfebd270b2f0660e86f056eeafdb26a4fb;p=clang

Add AVX2 intrinsics for pavg, pblend, and pcmp instructions. Also remove unneeded builtins for SSE pcmp. Change SSE pcmpeqq and pcmpgtq to not use builtins and just use vector == and >.
