Experimental support for RTS-only "ways" HEADS UP! This changes the way that the threaded RTS is used, and also the use of debugging RTSs: - We always build threaded and debugging variants of the RTS now. The --enable-threaded-rts configure option is ignored (and will be removed at some point). - New option: -debug enables the debugging RTS - New option: -threaded enables the threaded RTS. When the threaded RTS is stable enough, we might make it the default. The new options just cause a different variant of the RTS to be linked in, and they cause one or two extra options to be enabled too. The implementation is via the usual ways machinery in the compiler, except that these ways are labelled as RTS-only, and so don't require rebuilding all the libraries too. All of this means we can ship threaded and debugging RTSs with GHC, so that users don't need to fetch and build a GHC source tree to use them. I'd like to get this functionality into 6.2.1 if possible, so please test (I'm willing to stretch the definition of "interface change" to accomodate this, since having a threaded RTS available without having to build GHC will be a big win for the Visual Studio project).
