Owicki-Gries Reasoning for C11 RAR (Artifact)

Authors: Sadegh Dalvandi, Simon Doherty, Brijesh Dongol, and Heike Wehrheim

Published in: DARTS, Volume 6, Issue 2, Special Issue of the 34th European Conference on Object-Oriented Programming (ECOOP 2020)

Abstract
The paper "Owicki-Gries Reasoning for C11 RAR" introduces a new proof calculus for the C11 RAR memory model that allows Owicki-Gries proof rules for compound statements, including non-interference, to remain unchanged. The proof method features novel assertions specifying thread-specific views on the state of programs. This is combined with a set of Hoare logic rules that describe how these assertions are affected by atomic program steps. The artifact includes the Isabelle formalisation of the proof method introduced in the paper. It also contains the formalisation and proof of all case studies presented in the paper. All of the theorems are accompanied with their respective proofs.

Owicki-Gries Reasoning for C11 RAR

Authors: Sadegh Dalvandi, Simon Doherty, Brijesh Dongol, and Heike Wehrheim

Published in: LIPIcs, Volume 166, 34th European Conference on Object-Oriented Programming (ECOOP 2020)

Abstract
Owicki-Gries reasoning for concurrent programs uses Hoare logic together with an interference freedom rule for concurrency. In this paper, we develop a new proof calculus for the C11 RAR memory model (a fragment of C11 with both relaxed and release-acquire accesses) that allows all Owicki-Gries proof rules for compound statements, including non-interference, to remain unchanged. Our proof method features novel assertions specifying thread-specific views on the state of programs. This is combined with a set of Hoare logic rules that describe how these assertions are affected by atomic program steps. We demonstrate the utility of our proof calculus by verifying a number of standard C11 litmus tests and Peterson’s algorithm adapted for C11. Our proof calculus and its application to program verification have been fully mechanised in the theorem prover Isabelle.
