-/* Title:   MachineRegInfo.h
-   Author:  Ruchira Sasanka
-   Date:    Aug 20, 01
-   Purpose: Contains the description of machine register classes.
-
-   Notes:
-
-   A machine will have several register classes. For each register class, the
-   machine has to provide a class which is derived class of the virtual class
-   MachineRegClass. This virtual class itself is machine independent but 
-   the derived classes are all machine dependent.
