================
Comment at: lib/Transforms/Scalar/LoopInterchange.cpp:1467
+      if (InnerLoop->contains(InBB) ||
+          isa<PHINode>(PHI->getIncomingValueForBlock(InBB)))
+        continue;
----------------
This `isa<PHINode>` check seems weird; do you care whether it's specifically a reduction PHI node?
