Kind of unlikely given that neither arm64 nor ppc64el exists in Debian yet. If it were bootstrapped in Debian then of course I'd have used their binaries to get started. > I was thinking more about arm64, is it difficult to bootstrap here? > there was already support for armel and armhf, I don't think it is > impossible to find a binary for it... Really? If you can find a binary then please do point me at it. https://ghc.haskell.org/trac/ghc/ticket/7942 is still open upstream, and I don't see anything in the usual candidates for this sort of thing (Fedora, openSUSE, Gentoo). The best information I can find is in https://ghcarm.wordpress.com/2014/01/18/unregisterised-ghc-head-build-for-arm64-platform/, which does suggest that there might be some hope, but it's not at all clear whether GHC will get beyond stage1 - it'll still have to go round some more to rebuild itself and we'd have to confirm that it can build other Haskell packages as well before uploading it. To get started, I've uploaded an llvm-toolchain-3.4 change with the patch from LLVM HEAD referred to in that post, and then I suppose I can see if I can get our current package to bootstrap. I'm not promising anything, though; ghc is one of the most difficult packages in the archive to bootstrap from scratch.
