With split-objs, as far as I know, GHC only links in what you use (plus the module initialiser). split-objs was disabled for some GHC/OS X combinations recently, http://hackage.haskell.org/trac/ghc/ticket/4013 and 5008, maybe that applies to you, otherwise building GHC with object-splitting enabled and all libraries with split-objs should reduce code size significantly. Linking still tends to use a lot of memory with ld, on the appropriate platforms you could try using gold as the linker, that's reported to use less memory (and be faster). > Are there any plans, or at least some ideas, to rectify this? > One severe example of this is qtHaskell, where importing the top-level > module causes glacial compile (actually link) times and huge > executables.
