Dear GHC team, I tried to fix these problems myself, and three of the bugs had more or less trivial solutions (that hopefully are right): http://hackage.haskell.org/trac/ghc/ticket/5733 http://hackage.haskell.org/trac/ghc/ticket/5735 http://hackage.haskell.org/trac/ghc/ticket/5734 However, this makes this build failure appear on those arches as well:
ghc-stage1: panic! (the 'impossible' happened) (GHC version 7.4.0.20111219 for sparc-unknown-linux): pprGlobalReg: Unsupported register: CCCS
http://hackage.haskell.org/trac/ghc/ticket/5732 It seems that unregistered builds are generally broken, and that this is not specific to exotic architectures. Are unregistered builds still supported? Is this likely to be fixed for 7.4.1? Please note that support for non-x86-arches is not just an academic exercise: For example, I have a NAS device with an arm CPU (a NSLU2) that happily runs git-annex¹, which is written in Haskell. I wonder if we can help you in general with keeping these arches supported, e.g. by setting up build bots for GHC. Would that be possible? What would need to be done for that? Would a virtual machine on (some of) these arches that you can manage yourself be helpful? I’m not sure what Debian can do here, but if I know the requirements, I can talk to the right people.
