[PATCH] D135596: [AArch64] Canonicalize ZERO_EXTEND to VSELECT

[Paul Walker via Phabricator via llvm-commits]

paulwalker-arm added a comment.

Given you want to canonicalise to vselect is it worth doing this during lowering and removing the existing zext isel pattern? that way we can be sure all instances use the same idiom?  This looks like it would be equally useful for sign_extend's of predicates also?
