/* 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.
