The memory model is very important when writing lock free concurrent structures - especially cross platform.
It “worked” because the behavior was what most people would expect but I suspect there were lots of good around making it work and verifying when porting to different architectures. > On Oct 10, 2024, at 11:27 AM, Ian Lance Taylor <i...@golang.org> wrote: > > On Wed, Oct 9, 2024 at 11:30 PM will....@gmail.com > <will.fau...@gmail.com> wrote: >> >> It seems required to understand how Go programs work. >> >> If the memory model was never written, or is omitted from an implementation, >> would the concurrency features still be reliable and useful? > > People were able to write concurrent Go code successfully for years > before the memory model was written.
