Summary: We introduce a general verification framework based on program specialization to prove properties of the runtime behaviour of imperative programs. Given a program $$P$$ written in a programming language $$L$$ and a property $$\varphi$$ in a logic $$M$$, we can verify that $$\varphi$$ holds for $$P$$ by: (i) writing an interpreter $$I$$ for $$L$$ and a semantics $$S$$ for $$M$$ in a suitable metalanguage, (ii) specializing $$I$$ and $$S$$ with respect to $$P$$ and $$\varphi$$, and (iii) analysing the specialized program by performing a further specialization. We have instantiated our framework to verify safety properties of a simple imperative language, called SIMP, extended with a nondeterministic choice operator. The method is fully automatic and it has been implemented using the MAP transformation system.
