[PATCH] D22377: [SCEV] trip count calculation for loops with unknown stride

[Pankaj Chawla via llvm-commits]

pankajchawla updated this revision to Diff 65624.
pankajchawla added a comment.

- Added check to prove that the stride is truly unknown to ScalarEvolution so that the wrap flags are not propagated in edge cases.
- Removed unnecessary check for loopHasNoAbnormalExits() and loop entry guard.
- Fixed comments and the test.
