It formalizes the generation of PO (proof obligations) in a Hoare logic for a very basic imperative programming language. It proves the soundness and the completeness of the PO generation both in partial and total correctness. At last, it examplifies on a very simple example (a GCD computation) how the PO generation can simplify concrete proofs. Coq is indeed able to compute PO on concrete programs: we say here that the generation of proof obligations is reflected in Coq. Technically, the PO generation is here performed through Dijkstra's weakest-precondition calculus.""" flags: light-uninstall url { src: "https://github.com/coq-contribs/hoare-tut/archive/v8.7.0.tar.gz" checksum: "md5=8ba859070a0cf7578f6e50b70994aa9e" }
