#11668: SPEC has a runtime cost if constructor specialization isn't performed -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.3 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 simonpj): See `Note [Forcing specialisation]` in `SpecConstr`. The whole `SPEC` or `ForceSpecConstr` business (to force specialisation) is very unsatisfactory. It's just awaiting some bright person to have a better idea. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11668#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
