Such accesses are supported, subject to the same requirements for synchronization for concurrent accesses as for concurrent accesses to any object.

Extended alignments up to 2^{28} (bytes) are supported for objects of automatic storage duration. Alignments supported for objects of static and thread storage duration are determined by the ABI.

Valid alignments are powers of 2 up to and including 2^{28}.
