SMACK is both a modular software verification toolchain and a self-contained software verifier. It can be used to verify the assertions in its input programs. In its default mode, assertions are verified up to a given bound on loop iterations and recursion depth; it contains experimental support for unbounded verification as well. SMACK handles complicated feature of the C language, including dynamic memory allocation, pointer arithmetic, and bitwise operations.
Under the hood, SMACK is a translator from the LLVM compiler's popular intermediate representation (IR) into the Boogie intermediate verification language (IVL). Sourcing LLVM IR exploits an increasing number of compiler front-ends, optimizations, and analyses. Currently SMACK only supports the C language via the Clang compiler, though we are working on providing support for additional languages. Targeting Boogie exploits a canonical platform which simplifies the implementation of algorithms for verification, model checking, and abstract interpretation. Currently, SMACK leverages the Boogie and Corral verifiers.

We are very interested in your experience using SMACK. Please do contact Zvonimir or Michael with any possible feedback.
