#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: high | Milestone: 8.2.2 Component: Compiler | Version: 8.2.1-rc1 Resolution: | Keywords: | RecompilationCheck 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 George): I'll settle for what Simon suggested: " if the user manual documented the behaviour and the underlying principles. And describes how to work around it if you want something different." Whatever the solution, I'd like to be able to specify the optimization level of compilation, e.g. -O or -02 in a .ghci file as well as by an argument to ghci, so that it will take effect when I compile inside of emacs. i.e. in other words I'd like 13002 fixed too, if possible. The use case here is working with optimized compiled code in emacs/ghci, making changes and measuring the performance; thus you want to be able to compile those changes in emacs at a given optimization level. I think elaforge may want something more specific but I'll let him speak for himself. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13604#comment:24 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
