| Atomic operations including CAS (compare-and-swap), fetch & add and variants |
| suitable for low-level shared-memory synchronization. |
| |
| The implementation is using GCC's builtin atomic operations (available in GCC >= |
| 4) in C wrappers called through the FFI. See these links for background: |
| |
| * GCC manual: <https://gcc.gnu.org/onlinedocs/gcc/Atomic-Builtins.html> |
| |
| * GCC wiki: <https://gcc.gnu.org/wiki/Atomic> |
| |
| /Portability/: This package is primarily developed on a Linux system, but |
| should work wherever GCC >= 4 is available. It has been confirmed as working |
| on OSX. On Windows, it should work with Cygwin but currently fails for |
| vanilla Haskell-Platform 2010.1.0.0 as it still packages GCC 3.x. An |
| installer for updated versions of GCC is available at |
| <http://www.mingw.org/> and should make this package work in connection with |
| Haskell-Platform. Feedback on compatibility would be appreciated. |
| |
| /Testing:/ The following commands can be used to compile and run the test suite: |
| |
| > cabal unpack bits-atomic && cd bits-atomic-* # if not yet locally available |
| > cabal configure -ftest |
| > cabal build |
| > cabal test |
| |
| /Recent changes/: |
| |
| * 0.1.3: Documentation updates, especially on portability. No functional |
| changes. |
| |
| * 0.1.2: Avoid using System.FilePath in Setup.hs to fix build failure on hackage |
