Ok, thanks. Is it fair to say that these MSVC macros are assuming x86 architecture? Would this code still be safe on IA? (I don't personally have to deal with Itanium, I'm just curious now).
The Microsoft docs for the latest versions of their compiler say that volatile reads have a acquire semantics, so it should be fine. At the assembly language level, you do need a ld.acq instruction though rather than a simple ld. I haven't checked whether the compiler does this.
