Verifying Fortran Programs with CIVL

Abstract Fortran is widely used in computational science, engineering, and high performance computing. This paper presents an extension to the CIVL verification framework check correctness properties of programs. Unlike previous work that translates C, LLVM IR, or other intermediate formats before verification, our allows directly consume source files. We extended parsing, translation, analysis phases support Fortran-specific features such as array slicing reshaping, find program violations are specific Fortran, argument aliasing rule violations, invalid use variable function attributes, defects due Fortran’s unspecified expression evaluation order. demonstrate usefulness tool on a benchmark suite kernels extracted from real world application.
