[llvm-commits] CVS: llvm/include/llvm/ADT/SmallSet.h

[Chris Lattner]

Changes in directory llvm/include/llvm/ADT:

SmallSet.h updated: 1.5 -> 1.6
---
Log message:

Make SmallSet<whatever*, N> faster by transparently implementing it with
SmallPtrSet.  Some clients will need to use SmallPtrSet directly though if
they need to iterate over the set.
