Abstract
RGSep is a program logic for reasoning about the correctness of concurrent programs that combines rely-guarantee reasoning and separation logic. Although RGSep was initially developed for sequential consistency, we show that it is also sound under the much weaker release-acquire (RA) consistency model, which is a well-behaved subset of the C++11 concurrency model. Our result provides a simpler way to reason about RA programs than the state-of-the-art program logics that support weak memory consistency models.
