In apply, both of those compilers and CPUs reorder Directions to boost performance, these types of that solitary-threaded code continue to behaves exactly the same, although the reordering is observable from other threads.
will make sure the current system is completed from the CPU, prior to One more course of action accesses the variable
The final two are similar; "atomic" would be the default conduct (note that it's not in fact a search term; it's specified only by the absence of nonatomic -- atomic was included being a key phrase in the latest versions of llvm/clang).
