Chris Lattner 72af57f26c Rewrite this class, making the following improvements: ... 1. It now actually uses tarjan's algorithm, so it is a efficient inverse ackerman's function for union operations, not linear time. 2. It now stores one copy of the data in the set instead of two. 3. It now works for elements other than pointers. 4. It now has a more STL-like interface that exposes iterators instead of internal implementation details. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20677 91177308-0d34-0410-b5e6-96231b3b80d8		2005-03-19 05:14:29 +00:00
