public class RegisterVariable
extends java.lang.Object

Provides a representation of the register variable.

A register variable does not appear in the real assembly language. It can be used in the early stage of the assembly language generation. At this stage we use infinite register variables instead of finite registers. An then a global register allocator can map each register variable to a real register or a location on the stack.
Each register variable has an unique number.
