Comment(by GregWeber):

 So I started making changes based on the excellent pointers here and on
 the wiki page. I am not sending a pull request on github, but I though we
 could view the diff over there:
 https://github.com/gregwebs/ghc/compare/ghc:29a97fded4010bd01aa0a17945c84258e285d421...dependent

 I am very new to ghc, doing the best I can, but need some help. In
 particular I am wondering if this needs to be integrated with ModGuts. I
 seem to have something which might possibly work for the mkIfaceTc entry
 point, but not for mkIface entry point.
