Hello all,
Does GHC expose any primitives for things like atomic compare-and-swap? I can't seem to find anything in the docs.
Hello Gregory, I have recently published experimental and low-level FFI bindings to GCC's atomic primitives including CAS as 'bits-extras' on Hackage [1]. Instances for Int and Word types are included. This is likely lower-level than what you are after, but might still be handy for experimentation. Kind regards Gabriel [1]: http://hackage.haskell.org/packages/archive/bits-extras/0.1.0/doc/ html/Data-Bits-Atomic.html
