* Intermediate Representation (IR) of a program.
*
* This file defines a construct that keeps all information about a
* program. It is not the base class of
* all classes in a class hierarchy (as, e.g., "object" in java).
* - A degenerated graph that contains constant expressions.
- * - interprocedural outs state.
- * - a flag indicating validity of the interprocedural representation.
* - the output file name
