[PATCH] D118102: [LoopInterchange] Detect output dependency of a store instruction with itself

[Congzhe Cao via Phabricator via llvm-commits]

congzhe updated this revision to Diff 412596.
congzhe added a comment.

Updated a previous failing test case in `lcssa-preheader.ll`.

Previously this test could not be interchanged since dependence analysis would return [* *] as the direction vector for the output dependency detected, now it could be interchanged.
