[PATCH] D22886: [llvm] Loop Vectorization fault in collectLoopUni

[Gerolf Hoflehner via llvm-commits]

Gerolf added a comment.

Hm, FWIW this test doesn't reproduce with our compiler that exposes the problem at stage 2. And I still think when there are no uniforms within the loop there is no need to traverser the PHI nodes later.  
Since the patch clearly fixes an obvious problem I'm OK with a commit even w/o a test case - LGTM.
