LGTM, with some de-duplication suggested. I'm not an atomic wrangler, though, so I'd feel more comfortable if someone like @jfb could quickly double-check the implementation of the atomic operations.



================
Comment at: libcxx/include/atomic:1198
+_LIBCPP_INLINE_VISIBILITY 
+bool __cxx_atomic_compare_exchange_weak(volatile __cxx_atomic_lock_impl<_Tp>* __a, 
+                                        _Tp* __expected, _Tp __value, memory_order, memory_order) {
----------------
`__cxx_atomic_compare_exchange_weak` and `__cxx_atomic_compare_exchange_strong` seem the same. Should one just forward to the other?
