bits-extras: Efficient atomic and non-atomic bit operations not found in Data.Bits

[ bsd3, data, library ] [ Propose Tags ]

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.
