Webstore-order’ (TSO) memory model. We choose the TSO memory model as the basis of our extension for two reasons:(1)it is a mainstream practical weak memory model (followed by the x86 and SPARC architectures); and(2)it has an intuitive operational semantics in terms of processor-local buffers [Sewell et al. 2010]. We call our formal model PTSO ... WebJan 4, 2024 · We study the formal semantics of non-volatile memory in the x86-TSO architecture.
