#9872: Runing type functions is too slow -------------------------------------+------------------------------------- Reporter: simonpj | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: | Blocked By: None/Unknown | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by goldfire): Recall that `normaliseType` does "deep" normalisation, not just at top level -- it recursively tries to normalise all arguments. And, I don't think it would take long for it to try. If `normaliseType` doesn't remove a top-level type function, then flatten as normal, but it's still possible some good progress was made below top level. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9872#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
