Andrew Trick b4566a9999 Initialize SUnits before DAG building. Affect on SD scheduling and postRA scheduling: Printing the DAG will display the nodes in top-down topological order. This matches the order within the MBB and makes my life much easier in general. Affect on misched: We don't need to track virtual register uses at all. This is awesome. I also intend to rely on the SUnit ID as a topo-sort index. So if A < B then we cannot have an edge B -> A. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151135 91177308-0d34-0410-b5e6-96231b3b80d8	2012-02-22 06:08:11 +00:00
