#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): By the way, if the fix is really put off until 8.4.1, it means I'll have to skip a whole major version! This issue is a show stopper for my program, and I'd expect for any program that uses the GHC API for a REPL (maybe not that many, but still, it's a compelling GHC feature for me). It also makes interactive testing really slow, which for me makes it a show stopper for my style of development as well. If people like the "ghci allows but ignores -fhpc and -O" idea, I'd be happy to give the implementation a shot. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13604#comment:19 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
