Weakest precondition for general recursive programs formalized in coq.

Zhang, X. and Munro, M. and Harman, M. and Hu, L. (2002) 'Weakest precondition for general recursive programs formalized in coq.', in 15th International Conference on Theorem Proving in Higher Order Logics ; proceedings. Berlin: Springer, pp. 332-347. Lecture notes in computer science. (2410).

Abstract

This paper describes a formalization of the weakest precondition, wp, for general recursive programs using the type-theoretical proof assistant Coq. The formalization is a deep embedding using the computational power intrinsic to type theory. Since Coq accepts only structural recursive functions, the computational embedding of general recursive programs is non-trivial. To justify the embedding, an operational semantics is defined and the equivalence between wp and the operational semantics is proved. Three major healthiness conditions, namely: Strictness, Monotonicity and Conjunctivity are proved as well.
