-// Class RegClass
-//
-//   Implements a machine independent register class. 
-//
-//   This is the class that contains all data structures and common algos
-//   for coloring a particular register class (e.g., int class, fp class).  
-//   This class is hardware independent. This class accepts a hardware 
-//   dependent description of machine registers (TargetRegInfo class) to 
-//   get hardware specific info and to color an individual IG node.
-//
-//   This class contains the InterferenceGraph (IG).
-//   Also it contains an IGNode stack that can be used for coloring. 
-//   The class provides some easy access methods to the IG methods, since these
-//   methods are called thru a register class.
