[Florian Hahn via Phabricator via llvm-commits]

fhahn added inline comments.


================
Comment at: lib/Target/AArch64/AArch64LoadStoreOptimizer.cpp:885
+      // the store and load instruction, so we can just propagate the kill flag.
+      BitExtMI->addRegisterKilled(StRt, TRI);
+    }

Yep it should be OK, assuming there are no redundant kills later on, but then it's not the responsibility of this pass to clean that up.
