Static analysis via abstract interpretation of the happens-before memory model

Abstract. Memory models define which executions of multithreaded programs are legal. This paper formalises in a fixpoint form the happens-before memory model, an over-approximation of the Java one, and it presents a static analysis using abstract interpretation. Our approach is completely independent of both the programming language and the analysed property. It also appears to be a promising framework to define, compare and statically analyse other memory models
