kib c17f8bfdd5 Add the atomic_thread_fence() family of functions with intent to ... provide a semantic defined by the C11 fences with corresponding memory_order. atomic_thread_fence_acq() gives r | r, w, where r and w are read and write accesses, and | denotes the fence itself. atomic_thread_fence_rel() is r, w | w. atomic_thread_fence_acq_rel() is the combination of the acquire and release in single operation. Note that reads after the acq+rel fence could be made visible before writes preceeding the fence. atomic_thread_fence_seq_cst() orders all accesses before/after the fence, and the fence itself is globally ordered against other sequentially consistent atomic operations.
