================
Comment at: lib/Transforms/Vectorize/VPlan.cpp:618
+  // Block is NewBlock's idom.
+  VPDomTreeNode *NewBlockDT = DomTree.addNewBlock(NewBlock, Block /*IDom*/);
+
----------------
We should probably make sure we can use incremental DT updates via DeferredDominance and/or the DomTreeUpdater currently being developed.
