-/* Title:   PhyRegAlloc.h   -*- C++ -*-
-   Author:  Ruchira Sasanka
-   Date:    Aug 20, 01
-   Purpose: This is the main entry point for register allocation.
-
-   Notes:
-   =====
-
- * RegisterClasses: Each RegClass accepts a 
-   TargetRegClass which contains machine specific info about that register
-   class. The code in the RegClass is machine independent and they use
-   access functions in the TargetRegClass object passed into it to get
-   machine specific info.
-
- * Machine dependent work: All parts of the register coloring algorithm
-   except coloring of an individual node are machine independent.
