Hackage Matrix CI
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.
Enable extra internal checks.
Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info
