Smacc: a retargetable symbolic execution engine. SmacC is a symbolic execution engine for C programs. It can be used for program verification, bounded model checking and generating SMT benchmarks. More recently we also successfully applied SmacC for high-level timing analysis of programs to infer exact loop bounds and safe over-approximations. SmacC uses the logic for bit-vectors with arrays to construct a bit-precise memory-model of a program for path-wise exploration.
