Acquire and release semantics are crucial for the latter: reliable passing of information between threads. In fact, I would venture to guess that incorrect or missing

There are also atomic loads and stores, which are equally important. In this post, I’ll compare atomic loads and stores to their non-atomic counterparts at both the processor level and the C/C++ language leve
