#605: Optimisation: strict enumerations -------------------------------------+------------------------------------- Reporter: simonmar | Owner: Type: task | Status: new Priority: normal | Milestone: ⊥ Component: Compiler | Version: None Resolution: None | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: N/A Blocked By: | Blocking: Related Tickets: #6135 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by osa1): FWIW we can currently store strict enumerations as `Int#`s with Phab:D2424. Phab:D2436 allows returning `Int#` when returned enumeration is used strictly. Another patch is needed for extending demand analysis and passing `Int#` for strict enumerations. I actually have most of the code ready, but it needs rebasing it on current HEAD. IIRC some parts of the demand analysis were missing, but I can't remember exactly which parts. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/605#comment:21 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
