AN INTEGRATED ENVIRONMENT FOR REUSE REENGINEERING C-CODE

The paper presents an integrated environment implemented in Prolog for reuse reengineering existing C systems. Different tools developed in the RE2 project are integrated in the environment through sharing a fi ne-grained representation for C programs, the Combined C Graph (CCG). Different views of a system can be abstracted and visualised from the data-base of Prolog facts implementing its CCG representation. Softwar e metric tools evaluate the reengineering costs, while reengineering o perations are expressed as transformation rules and a symbolic executo r allows the production of the reusable module's specification.
