atomic-primops: A safe approach to CAS and other atomic ops in Haskell.
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.
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
Changes in 0.4:
Further internal changes, duplicate
casroutine well as barriers.
Unboxedcounter variant that uses movable ByteArrays on the GHC heap.
Changes in 0.5:
Remove dependency on bits-atomic unless a flag is turned on.

Enable extra internal checks.
Enable a dependency on bits-atomic and in turn provide a foreign implementation of Counter.
Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info
