================
Comment at: llvm/lib/Analysis/ScalarEvolution.cpp:6063
 
+  if (V->getType()->isPointerTy()) {
+    // We can't model pointer selects in SCEV in their generality.
----------------
Does `createNodeForSelectViaUMinSeq` do anything useful for pointers? I guess it maybe an else-if then (with pointer check coming first).
