[PATCH] D140382: [CodeGen] Add user interface for DetectDeadLanes

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: llvm/lib/CodeGen/DetectDeadLanes.cpp:499
+    bool LocalChanged;
+    std::tie(LocalChanged, Again) = runOnce(MF);
+    Changed |= LocalChanged;
----------------
Do we need to skip the "Mark operands as dead/unused." part of runOnce for this usage?
