Establishes memory synchronization ordering of non-atomic and relaxed atomic accesses, as instructed by order, between a thread and a signal handler executed on the same thread. This is equivalent to Template:cpp, except no CPU instructions for memory ordering are issued. Only reordering of the instructions by the compiler is suppressed as order instructs, e.g. writes cannot be moved past Template:cpp and reads cannot be moved ahead of Template:cpp.
