#13604: ghci no longer loads dynamic .o files by default if they were built with -O -------------------------------------+------------------------------------- Reporter: George | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.4.1 Component: GHCi | Version: 8.2.1-rc1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D3514 Wiki Page: | -------------------------------------+------------------------------------- Comment (by elaforge): I just ran into this issue myself. The main thing I have to add is to note that this issue also affects -fhpc, so whatever solution should take that into account too. I took a look through FlagChecker.hs for other candidates, but didn't see anything else. A simple fix would be for ghci to note that -fhpc or -O are being ignored, but still include them in its flag hash when it does the recompilation check. I didn't notice that suggestion in the discussion above. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13604#comment:18 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
