Automated inference of ACSL function contracts using TriCera

Sammanfattning: This thesis explores synergies between deductive verification and model checking, by using the existing model checker TriCera to automatically infer specifications for the deductive verifier Frama-C. To accomplish this, a formal semantics is defined for a subset of ANSI C, extended with assume statements, called Csmall. Then, it is shown how a Hoare logic contract can be translated into statements in Csmall, and the defined formal semantics is used to prove that the translation is correct. Furthermore, it is shown that the translation can be applied also to a real specification language. This is done by defining a subset of ACSL, called ACSLsmall, and giving a formal semantics also for this. Lastly, two examples are provided showing that the theory developed in this thesis can be applied to automatically infer ACSL function contracts.
