Yes, the original test doesn't really check for that. I'll push a commit to improve the test in that regard separately and will also include the vector loop. fhahn: Yes, the original test doesn't really check for that. I'll push a commit to improve the test in… | |||||

this should check that we actually don't run the extra passes when there's no vectorization, e.g.
O2-NOT: Running pass: ...
