The Static Analyzer Frama-C in SV-COMP (Competition Contribution)

Abstract

Abstract Frama-C is a well-known platform for source-code analysis of programs written in C. It can be extended via its plug-in architecture by various analysis backends and features an extensive annotation language called ACSL. So far it was hard to compare Frama-C to other software verifiers. Our competition participation contributes an adapter named Frama-C-SV, which makes it possible to evaluate Frama-C against other software verifiers. The adapter transforms standard verification tasks (from the well-known SV-Benchmarks collection) in a way that can be understood by Frama-C and produces a verification witness as output. While Frama-C provides many different analyses, we focus on the Evolved Value Analysis (EVA), which uses a combination of different domains to over-approximate the behavior of the analyzed program.
