[PATCH] D85499: [X86] Canonicalize andnp for bitmask arithmetic

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

I kind of think we shouldn't change the canonical form for masks and we should handle the mask case of vselect in generic DAG combine like we do in InstCombine. Maybe we could handle the non mask case there instead too, but that depend on whether we can form ANDNP afterwards.
