[PATCH] D67645: [aarch64] add def-pats for dot product

[Sebastian Pop via Phabricator via llvm-commits]

sebpop added a comment.

I looked at both the SLP and loop vectorizer and I think this is more work than I can do right now.

not a this time.

Instruction selection and vectorizers are orthogonal.
I don't think that isel work would become obsolete with a vectorizer emitting dot builtins:
there will be need to recognize the dot instructions in code that has not been processed by the vectorizers.
