[PATCH] D93317: [LV] Vectorize (some) early and multiple exit loops

[Philip Reames via Phabricator via llvm-commits]

Ok, I see what's going on w/Florian's example.  It's an interaction with block predication and early exits.  Essentially, block predication expects to be able to add uses of any condition in the loop, and the dead code elimination has eliminated the exit condition in the vector loop.  I can restrict the legality slightly to avoid this interaction easily enough, but I want to think a bit first if there's a clean integration.
