#13604: regression in ghc 8.2.1-rc1 (8.2.0.20170404) -------------------------------------+------------------------------------- Reporter: George | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 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): Wiki Page: | -------------------------------------+------------------------------------- Comment (by George): Thanks, that answers my question, you can do it as you described. Also you can specify those options in your .ghci file and that works as would be expected. So the question seems to be, if you have an object file compiled with flags different than the ghci flags (possibly the default ones) should ghci load it (as it did in 8.0.2) or should it compile the source into interpreted byte code and load that (as it does now) I think I prefer the old behavior, if you want interpreted byte code, remove the object file otherwise load will load your object file as is. However if we want to change this behavior to what it is currently I could live with that as long as the documentation is clear about the change and the current behavior. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13604#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
