Automating Memory Model Metatheory with Intersections

Authors: Aristotelis Koutsouridis, Michalis Kokologiannakis, and Viktor Vafeiadis

Abstract

In the weak memory consistency literature, the semantics of concurrent programs is typically defined as a constraint on execution graphs, expressed in relational algebra. Prior work has shown that basic metatheoretic questions about memory models are decidable as long as they can be expressed as irreflexivity and emptiness constraints over Kleene Algebra with Tests (KAT), a condition that rules out practical memory models such the C/C++ and the Linux kernel models. In this paper, we extend these results to memory models containing arbitrary intersections with uninterpreted relations. We can thus automatically establish compilation correctness and derive efficient incremental consistency checkers for RC11, LKMM, and other memory models.
