The value of required_alignment
is the required alignment for an object to be referenced by an atomic reference, which is at least alignof(T)
Notes
Hardware could require that an object to be referenced by an atomic_ref<T>
have stricter alignment than other T
objects, and whether operations on an atomic_ref
