[PATCH] D141924: [IR] Add new intrinsics interleave and deinterleave vectors

[Philip Reames via Phabricator via llvm-commits]

reames added a comment.

I plan on doing a real review in a moment, but let me start with a high level comment.

I am one of the folks who thinks long term that we need a generalized means for describing shuffles with runtime masks.  I had started a few months ago to put together a proposal for the same, but it stalled due to lack of attention.  Despite this long term direction, I want to explicitly say that I do *not* oppose the addition of intrinsics in the near term to solve the same problem.  We need to unblock progress here, and we can migrate at a later time to a more general solution if one comes along.
