/* Title: LiveVarMap.h
Author: Ruchira Sasanka
Date: Jun 30, 01
Purpose: This file contains the class for a map between the BasicBlock class
and the BBLiveVar class, which is a wrapper class of BasicBlock
used for the live variable analysis. The reverse mapping can
be found in the BBLiveVar class (It has a pointer to the
corresponding BasicBlock)
