#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: #5692 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by JulianLeviston): As discussed on IRC, I encountered an issue where moving the code into `GHC.Real` doesn't help because Stage 1 is not using *that* `GHC.Real`, it's using the module from the GHC being used to compile the target GHC rather than the target GHC itself. So, what I'm going to do is spend a little bit of time to summarize my understanding of exactly what my attempt is currently and how to understand the code I've written so that we're all on the same page and others can help me more easily. Stay tuned :) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15646#comment:65 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
