Experience compiling Fortran to program dependence graphs
Karl J. Ottenstein, Steven J. Ellcey · Software Practice and Experience · 1992
Abstract The program dependence graph (PDG) is being used in research projects for compilation to parallel architectures, program version integration and program semantics. This paper describes the methods used in a prototype Fortran‐to‐PDG translator called the PDG Testbed. Implementation decisions and details of the PDG Testbed project are described as a complement to the formal papers detailing the abstract PDG. In addition, experimental results are given that show the storage consumption for a PDG relative to a conventional internal representation as well as execution times for several analysis and optimization steps.
