#14596: Remove uses of unsafeGlobalDynFlags for state hack -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 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:D4265 Wiki Page: | -------------------------------------+------------------------------------- Changes (by bgamari): * cc: DemiMarie (added) * differential: => Phab:D4265 Comment: DemiMarie has a patch (Phab:D4265) implementing this. Unfortunately it's quite invasive. On the call Simon proposed an alternate way forward: rather than making the decision of whether to apply the state hack during simplification, instead push the decision up to the typechecker. The `State#` tycon would carry whether or not it should be considered for the state hack. Simonpj will likely pop up here and fill in more details later. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14596#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
