Research into the working practices of software engineers has shown the need for integrated browsing and searching tools which include graphical visualisations linked back to the source code under investigation. In addition, for assembler maintenance and re-engineering there is an even greater need for sophisticated control flow analysis, data flow analysis, slicing and migration technology. All these technologies are provided by the FermaT Workbench: an industrial-strength assembler re-engineering workbench consisting of a number of integrated tools for program comprehension, migration and re-engineering. The various program analysis and migrations tools are based on research carried out over the last sixteen years at Durham University, De Montfort University and Software Migrations Ltd., and make extensive use of program transformation theory.
