The driver determines file based on whether an -o option is given. If it is, the driver uses its argument but with a suffix of .d, otherwise it takes the name of the input file, removes any directory components and suffix, and applies a .d suffix. If -MD is used in conjunction with -E, any -o switch is understood to specify the dependency output file, but if used without -E, each -o is understood to specify a target object file. Since -E is not implied, -MD can be used to generate a dependency output file as a side-effect of the compilation process. }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11281#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
