My understanding is that the GSoC project was to use Lennart Augustsson's
llvm bindings that are on hackage.

However discussing the requirements for DDC with Ben Lippmeier I think
our needs may actually be better met with David Terei's LLVM interface.
Ben's objections to Lennart's bindings are:

  - Use of non Haskell 98 extensions which makes out bootstrapping
    problem more difficult.

  - It uses FFI rather than being pure Haskell code like David's.

  - It seems very imperative. It would be nicer for it to be an DDC
    core language AST to LLVM AST transformation followed by a pretty
    print stage to generate the LLVM IR code.

Cheers,
Erik
