@vathpela@infosec.exchange @kernellogger@hachyderm.io I wonder what SPARC designers were worried about being compatible with - what multiprocessor systems and multithreaded software was commonly around at the time? (An x86 oddity I don't think is mentioned there is that it has a get-out, where a core accessing it's own writes is allowed to go out of order; some other architectures are stricter so emulation on x86 need orderings enforcing still).
