* Generalize atomic operations for atomic_ops.h.
* Should not be included directly.
*
* We make no attempt to define useless operations, such as
* AO_nop_acquire
* AO_nop_release
*
* We have also so far neglected to define some others, which
* do not appear likely to be useful, e.g. stores with acquire
* or read barriers.
*
* This file is sometimes included twice by atomic_ops.h.
* All definitions include explicit checks that we are not replacing
* an earlier definition. In general, more desirable expansions
* appear earlier so that we are more likely to use them.
*
* We only make safe generalizations, except that by default we define
* the ...dd_acquire_read operations to be equivalent to those without
* a barrier. On platforms for which this is unsafe, the platform-specific
* file must define AO_NO_DD_ORDERING.
