[PATCH] D75145: [PassManager] adjust VectorCombine placement

[Bjorn Pettersson via Phabricator via llvm-commits]

bjope added a comment.

When you say "phase ordering bug" that is about not generating as optimized code as expected, right? Not ending up with miscompiles (or compiler crashes)?

(just curious since we got regressions downstream after this patch... haven't looked deeper at that and it could just be some limitations in our backend, but could be nice to know if it is "safe" for us to revert this downstream while investigating)
