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.
On OSX libgcc_s is only supplied as a dynamic library, which GHC doesn't
seem to be able to link with. Any ideas would be appreciated.
