We report on the process for formal concurrency modelling at Arm. An initial formal
consistency model of the Arm achitecture, written in the cat language, was published and …

The C/C++ 11 memory model defines the semantics of concurrent memory accesses in
C/C++, and in particular supports racy" atomic" accesses at a range of different consistency …

ARM has a relaxed memory model, previously specified in informal prose for ARMv7 and
ARMv8. Over time, and partly due to work building formal semantics for ARM concurrency, it …

The field of concurrent separation logics (CSLs) has recently undergone two exciting
developments:(1) the Iris framework for encoding and unifying advanced higher-order CSLs …

The Rust programming language supports safe systems programming by means of a strong
ownership-tracking type system. In their prior work on RustBelt, Jung et al. began the task of …

A memory consistency model (MCM) is the part of a programming language or computer
architecture specification that defines which values can legally be read from shared memory …

We present GenMC, a model checking algorithm for concurrent programs that is parametric
in the choice of memory model and can be used for verifying clients of concurrent libraries …

GenMC is an LLVM-based state-of-the-art stateless model checker for concurrent C/C++
programs. Its modular infrastructure allows it to support complex memory models, such as …

We develop a new intermediate weak memory model, IMM, as a way of modularizing the
proofs of correctness of compilation from concurrent programming languages with weak …

This paper introduces ctrees, a monad for modeling nondeterministic, recursive, and impure
programs in Coq. Inspired by **a et al.'s itrees, this novel data structure embeds …
