An integrated program representation and toolkit for the maintenance of C programs

Abstract

An integrated environment for the maintenance of software systems written in C is presented. This environment supports all of the C language, including the C preprocessor. The underlying program representation for the environment supports multiple views of the subject system, including source code, syntactic, static semantic, control flow and data flow views. A transformation toolkit supports structured changes to the representation and automatically updates all dependent views. Modifications in one view are reflected in related views.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
