But if the interrupt accesses a variable and a normal function accesses the variable as well, the access needs to be 'volatile' (not cached into a register by the compiler; not closely related to this discussion) and atomic, as the interrupt might occur in between multiple partial writes. So the variable should be shared, although there's no multithreading (in the usual sense).
Single publishing (loggers, singletons) doesn't need atomic load: https://forum.dlang.org/post/ozssiniwkaghcjvrl...@forum.dlang.org
