================
Comment at: lib/Transforms/Scalar/GVN.cpp:2460
                              UndefValue::get(Phi.getType()));
+        if (MD && Phi.getType()->isPtrOrPtrVectorTy())
+          MD->invalidateCachedPointerInfo(&Phi);
----------------
The isPtrOrPtrVectorTy check is unnecessary; invalidateCachedPointerInfo does its own check.
