#190: extension ForeignFunctionInterface should imply -fvia-C for ghc --------------------------+------------------------------------------------- Reporter: duncan | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal | Version: 1.2.3.0 Severity: normal | Resolution: Keywords: | Difficulty: normal Ghcversion: 6.8.1 | Platform: Linux --------------------------+------------------------------------------------- Comment (by duncan): So what is the recommendation from GHC HQ these days? From the [http://haskell.org/ghc/docs/6.8.2/html/users_guide/ffi-ghc.html #glasgow-foreign-headers GHC user guide:] Note that this approach is only ''essential'' for returning floats (or if sizeof(int) != sizeof(int *) on your architecture) but is a Good Thing for anyone who cares about writing solid code. You're crazy not to do it. Has that recommendation changed? Perhaps we don't want to always use -fvia-C if we're doing FFI for the reasons mentioned above, but what should the default be? Sounds like it should still be -fvia-C and not -fasm. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/190#comment:3 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
