[PATCH] D37669: [X86][intrinsics] lower _mm[256|512]_mask[z]_set1_epi[8|16|32|64] intrinsic to IR

[jina via Phabricator via llvm-commits]

jina.nahias updated this revision to Diff 114807.
jina.nahias added a comment.

there is a problem with intrinsics that use 64 bit masks (e.g. *epi8) have a sub optimal asm code (hundreds of code lines) on a 32bit machine when running fast-isel flag .  working on a solution and updating in another patch.
