================
Comment at: llvm/include/llvm/Analysis/ScalarEvolution.h:1505
+  /// Stores all SCEV that use a given SCEV as its direct operand.
+  DenseMap<const SCEV *, SmallPtrSet<const SCEV *, 16> > SCEVUsers;
+
----------------
I would expect that on average there's less than 16 users for a given SCEV.
