[David Li via Phabricator via llvm-commits]

davidxl added inline comments.


================
Comment at: lib/CodeGen/MachineBlockPlacement.cpp:2649
 
+  unsigned TailDupSize = TailDupPlacementThreshold;
+
----------------
Is it better to have two parameters: TailDupThreshold and TailDupAggressiveThreshold? The later can be used for O3.
