Chris Lattner 4ff0b9636d Substantially improve the DSA code by removing 'forwarding' nodes from ... DSGraphs while they are forwarding. When the last reference to the forwarding node is dropped, the forwarding node is autodeleted. This should simplify removeTriviallyDead nodes, and is only (efficiently) possible because we are using an ilist of dsnodes now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11175 91177308-0d34-0410-b5e6-96231b3b80d8		2004-02-08 01:27:18 +00:00
