-/* Title:   LiveRangeInfo.h  -*- C++ -*-
-   Author:  Ruchira Sasanka
-   Date:    Jun 30, 01
-   Purpose: 
-
-   This file contains the class LiveRangeInfo which constructs and keeps 
-   the LiveRangMap which contains all the live ranges used in a method.
-
-   Assumptions: 
-
-   All variables (llvm Values) are defined before they are used. However, a 
-   constant may not be defined in the machine instruction stream if it can be
-   used as an immediate value within a machine instruction. However, register
-   allocation does not have to worry about immediate constants since they
-   do not require registers.
-
-   Since an llvm Value has a list of uses associated, it is sufficient to
-   record only the defs in a Live Range.
