Matching Logic
Operational semantics are typically used to derive concrete program behaviours, but not to specify and prove properties about programs. The latter are traditionally done using axiomatic semantics. Unfortunately, axiomatic semantics of real languages are rather complex, so correctness proofs are necessary in order to trust the proven properties. Moreover, such proofs have to be maintained as the language changes, which is generally perceived as a burden. Ideally, we would like to have one language semantics, with that semantics used both for deriving program behaviours and for verifying programs.
Matching logic allows us to regard a language through both operational and axiomatic lenses at the same time, making no distinction between the two. A programming language is given a semantics as a set of rewrite rules. A language-independent proof system can then be used to derive both operational behaviours and formal properties of a program. In other words, one matching logic semantics fulfils the roles of both operational and axiomatic semantics in a uniform manner. The state structure plays a crucial role in matching logic semantics. Program states are represented as algebraic datatypes called (concrete) configurations, while program state specifications are represented as configuration terms, with variables and constraints over them, called (configuration) patterns. A pattern specifies those configurations that match it.

Download and Online Interface
We have implemented a proof-of-concept matching logic verifier for a fragment of C, called MatchC.

--- This link provides an online interface to running MatchC
- Download --- We recommend to first try it online (see the link above)

We have formalized the proof system in Coq, including the soundness proof and applications. The Coq latest files are available here.
