Ben Pfaff	8917f72cbb	ovs-atomic: Delete atomic, atomic_flag, ovs_refcount destroy functions. ... None of the atomic implementations need a destroy function anymore, so it's "more standard" and more convenient for users to get rid of them.

Ben Pfaff	6a36690c20	ovs-atomic-types: Move into ovs-atomic.h. ... Every implementation used this same code, so it makes sense to centralize it. Signed-off-by: Ben Pfaff <blp@nicira.com> Acked-by: Andy Zhou <azhou@nicira.com>	2014-03-13 12:45:42 -07:00
Ben Pfaff	7d53f6b022	ovs-atomic: Factor type declarations out of most implementations. ... This reduces duplicate code. Signed-off-by: Ben Pfaff <blp@nicira.com> Acked-by: Andy Zhou <azhou@nicira.com>	2014-03-13 12:45:19 -07:00
Ben Pfaff	c5f81b20da	ovs-atomic: Add atomic_destroy() and use everywhere it is needed. ... C11 is able to require that atomics don't need to be destroyed, but some of the OVS implementations do. Signed-off-by: Ben Pfaff <blp@nicira.com>	2014-01-08 17:13:30 -08:00
Ben Pfaff	29ab0cf77c	ovs-atomic: Add native Clang implementation. ... With this implementation I get warnings with Clang on GNU/Linux when the previous patch is not applied. This ought to make it easier to avoid introducing new problems in the future even without building on FreeBSD.

Ben Pfaff	31a3fc6e3e	ovs-atomic: New library for atomic operations. ... This library should prove useful for the threading changes coming up. The following commit introduces one (very simple) user.
