[PATCH] D144298: [Local][SimplifyCFG][GVN] Handle !nontemporal in combineMetadata

[Daniel Woodworth via Phabricator via llvm-commits]

dwoodwor-intel updated this revision to Diff 499237.
dwoodwor-intel retitled this revision from "[Local][SimplifyCFG] Handle !nontemporal in combineMetadata" to "[Local][SimplifyCFG][GVN] Handle !nontemporal in combineMetadata".
dwoodwor-intel added a comment.

I've added a new GVN test to exercise the `patchReplacementInstruction` change, and I also added a GVNSink test to make sure this change works properly in that pass too even though it uses the same code path as SimplifyCFG. Are there other passes I should add tests for/update to better combine !nontemporal metadata?
