[PATCH] D83311: [CodeMoverUtils] Add optional data dependence checks using MSSA

[Bardia Mahjour via Phabricator via llvm-commits]

bmahjour added inline comments.


================
Comment at: llvm/lib/Transforms/Utils/CodeMoverUtils.cpp:255
+        // write after write dependency on same memory location
+        if (InstMA == CurInstLastDefMA)
+          return true;
----------------
We also need to check for `InstLastDefMA == CurInstLastDefMA` in case both definitions are clobbered by the same memory phi.
