[PATCH] D67948: [LV] Interleaving should not exceed estimated loop trip count.

[Hideki Saito via Phabricator via llvm-commits]

hsaito added a comment.

We have observed some performance regressions, presumably because the vectorized code started to kick-in on short estimated trip count loops (as opposed to skipping vector code and execute scalar code). We'll try following up with cost model tuning. I'm not too surprised if others also hit a similar issue. Overall, though, that's the right direction to head to.
