I'm not exactly sure how llvm-g++ works.  I think it goes through the
standard gcc sequence (gimple, rtl, and such) but then outputs LLVM
(http://llvm.org/docs/LangRef.html), which is the intermediate
representation used by the rest of the chain.  To make an LLVM backend
you would not need to deal with RTL and such at all.

There's a name change in progress to make it clearer that what's now
called LLVM is much more than just the LLVM language :)
