This paper reports on the use of formal specifications in the development of a software maintenance tool for specializing imperative programs, which have become very complex due to extensive modifications. The tool is specified in terms of inference rules and operates by induction on the abstract syntax. The correctness of these rules is proved using rule(More)
We describe a technique and a tool supporting partial evaluation of Fortran programs, i.e. their specialization for specific values of their input variables. We aim at understanding old programs, which have become very complex due to numerous extensions. From a given Fortran program and these values of its input variables, the tool provides a simplified(More)
