[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added inline comments.


================
Comment at: llvm/lib/Transforms/Utils/ScalarEvolutionExpander.cpp:2348-2349
     SmallVectorImpl<SCEVOperand> &Worklist) {
-  if (BudgetRemaining < 0)
+  if (!BudgetRemaining.isValid() || BudgetRemaining < 0)
     return true; // Already run out of budget, give up.
 
----------------
What happens without the `isValid()` check?
