#15646: ghci takes super long time to find the type of large fractional number -------------------------------------+------------------------------------- Reporter: Johannkokos | Owner: | JulianLeviston Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: GHCi | Version: 8.4.3 Resolution: | Keywords: newcomer Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by JulianLeviston): Still floundering :). Anyone have any suggestions about the following? it's still just as slow as before, it seems. {{{ HsRat _ fl _ -> case fl of FL { fl_signi = fl_signi, fl_exp = fl_exp } -> do mkRational <- dsLookupGlobalId mkRationalName litI <- mkIntegerExpr fl_signi litE <- mkIntegerExpr fl_exp return ((Var mkRational) `App` litI `App` litE) }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15646#comment:46 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
