Duplicate GHC RTS barriers and support non -threaded.--- 0.4 -- Duplicate 'cas' as well as barriers. Add fetchAdd on ByteArray, Counter.Unboxed.--- 0.4.1 -- Add advance support for GHC 7.8--- 0.5 -- Nix Data.Atomics.Counter.Foreign and the bits-atomic dependency.--- 0.5.0.2 -- IMPORTANT Bugfix release.--- 0.6 -- add atomicModifyIORefCAS, and bump due to prev bugfixes--Synopsis: A safe approach to CAS and other atomic ops in Haskell.--Description:-- After GHC 7.4 a new `casMutVar#` primop became available, but it's- difficult to use safely, because pointer equality is a highly- unstable property in Haskell. This library provides a safer method- based on the concept of "Tickets".- .- Also, this library uses the "foreign primop" capability of GHC to- add access to other variants that may be of- interest, specifically, compare and swap inside an array.- .- Note that as of GHC 7.8, the relevant primops have been included in GHC itself.- This library is engineered to work pre- and post-GHC-7.8, while exposing the - same interface.- .- Changes in 0.3:- .- * Major internal change. Duplicate the barrier code from the GHC RTS and thus - enable support for executables that are NOT built with '-threaded'.- .- Changes in 0.4:- . - * Further internal changes, duplicate 'cas' routine well as barriers. - .- * Add `fetchAddByteArrayInt`- .- * Add an `Unboxed` counter variant that uses movable "ByteArray"s on the GHC heap.- .- Changes in 0.5:- . - * Remove dependency on bits-atomic unless a flag is turned on.- . - Changes in 0.5.0.2:- .- * IMPORTANT BUGFIXES - don't use earlier versions.
