It's worth noting that if a SmallPtrSet is large enough, it starts to slow down lookups, since the "small" isn't a proper hashtable. I'm not sure where exactly the point is that lookups start becoming slower than a DenseMap lookup, though. -Eli _______________________________________________ cfe-commits mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/cfe-commits
