#15364: Replace the atomicModifyMutVar# primop -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: 8.8.1 Component: Runtime System | Version: 8.5 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D4884 Wiki Page: | -------------------------------------+------------------------------------- Changes (by dfeuer): * cc: fryguybob (added) Comment: I've put up a differential that implements everything except `atomicSwapMutVar#`, and that sets the stage for adding that as well. I could use some help with `atomicSwapMutVar#`, which is the only primop I ''can't'' implement by just removing code from other ones. I think we'll probably need to add C bits to get access to the necessary exchange intrinsic. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15364#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
