Per-Location Simulation

Abstract

Simulation/bisimulation is one of the most widely used frameworks for proving program equivalence/semantic preservation. In this paper, we propose a new per-location simulation (PLS) relation that is simple and suitable for proving that a compiled program semantically preserves its original program under a CFG-based language with a real-world, C/C++ like, weak memory model. To the best of our knowledge, PLS is the first simulation framework weaker than the CompCert[26]/CompCertTSO[47] one that is used for proving compiler correctness. With a combination of PLS, the compiler proof-framework Morpheus[34], and a language semantics with a weak memory model, we are able to prove that programs are semantically preserved through a transformation. All the definitions and proofs have been implemented in Isabelle/HOL.
