#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): Update: Been working on this today; I've done the changes required in `BasicTypes.hs` and I'm on `Lexer.hs` changes now. It's going well, currently in the process of refactoring `readHexRational` to use a new function for reading the significand and exponent out of hex floating literals. (from `Util.hs`). Just finished doing that for `readRational`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15646#comment:31 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
