[PATCH] D27690: [LV] Don't vectorize when we have a static bound on trip count

[Hal Finkel via Phabricator via llvm-commits]

hfinkel added a comment.

Can you please remind me why we're doing this? A loop with a small trip count should be unrolled if it is small, so we should really only be seeing here loops with small trip counts that have large bodies. That being the case, if vectorization looks profitable, why isn't it?
