================
Comment at: llvm/lib/CodeGen/CodeGenPrepare.cpp:6173
+            NewBaseInsertBB = SplitEdge(NewBaseInsertBB,
+                                        Invoke->getNormalDest(), &getDT(), LI);
             NewBaseInsertPt = NewBaseInsertBB->getFirstInsertionPt();
----------------
This is a bit unfortunate, would be better if SplitEdge accepted DTU. But it looks like that would take a larger refactoring.
