#12990: Partially applied constructors with unpacked fields simplified badly -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by rwbarton): Inlining `$WFoo` into `silly1` and then beta-reducing would also fix it (case of known constructor). I think that GHC thinks the inlining will be fruitless here for some reason. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12990#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
