The library only defines a single atomic API for adding to a 32-bit and 64-bit integers, but includes a lot of complex preprocessor logic to detect platforms that are probably not relevant to the library, and are likely untested. There is a lack of atomic exchange, atomic compare-exchange, atomic fetch. Atomic fetch, in particular, is useful for read operations on integral variables that may be modified concurrently, without the need to introduce a lock (relevant to CDRIVER-4114).
The pending solution for CDRIVER-4113 also makes use of these additional atomic operations.
