Overview

Each pass of the SUIF compiler represents an input program using a set of complex data structures. Thus when a compiler pass needs to modify the original program, it needs to manipulate these data structures. A simple five line C program may need a few hundred complex structures to represent the program in a SUIF compiler pass. Changing a single line of the original C program while executing the compiler pass means updating many of these data structures. These data structures are highly interdependent and have to conform to a complex set of rules.

The goal of the builder is to abstract these complexities away from a programmer writing a pass for the SUIF compiler. When a programmer needs to change or add new code to the input program, the builder will provide a simple and nice abstraction. Advantages of using the builder are:
