================
Comment at: lib/Transforms/Utils/LoopUnrollPeel.cpp:134
+        // so we can ignore it. Otherwise our Phi lies in chain with depth + 1.
+        auto It = InvariantDepth.find(IncPhi);
+        if (It != InvariantDepth.end()) {
----------------
Actually this one is not needed, because if the value is present in map, we will return it early in CalculateInvariantDepth.
