[Sanjoy Das via Phabricator via llvm-commits]

sanjoy added inline comments.


================
Comment at: lib/Analysis/ScalarEvolution.cpp:2681
   SmallVector<const SCEV *, 4> Ops;
+  SmallSet<const SCEV *, 4> Visited;
   Ops.push_back(StartExpr);
----------------
Can you use `SCEVExprContains` here?
