[PATCH] D75388: Add a pass to identify certain shuffle_vector and transform it into target specific intrinsics.

[Sanjay Patel via Phabricator via llvm-commits]

spatel added a comment.

The title of this patch confused me. This is not adding a pass; it is extending existing passes.
I did not see an answer to @dmgreen's questions - maybe the biggest one: why is this transform not done entirely in SelectionDAG?
And why would we want AArch-specific "tbl1" pattern-matching in the generic VectorUtils.h?
