[PATCH] D67905: [LV] Vectorizer should adjust trip count in profile information

[Evgeniy via Phabricator via llvm-commits]

ebrevnov updated this revision to Diff 229260.
ebrevnov added a comment.

I realized that current implementation has a flaw and and we should take into account that actual number of iterations is one greater than back edge taken count. In addition I believe that current structuring of calculations is easier for understanding.
