The bits-extras package
Mostly wraps low-level bit operations provided by GCC builtins, which translate to specialized instructions where available.
Atomic operations include CAS (compare-and-swap), lock, fetch & add and similar primitives suitable for low-level shared-memory synchronization.
Primitives from the Extras subpackage would be useful to have in the proper Data.Bits package, although this would probably require broader support across different compiler backends.
