Hi Cedric, Chris,

I had a similar thought, namely that having a simple 16/8-bit arch in  
clang+LLVM would be a great instructional tool. I'm currently  
whipping  up a quick back end for the 16-bit LC-3 instructional  
architecture (http://en.wikipedia.org/wiki/LC-3). I thought it'd be a  
good example because it is both extremely simple, but also quite  
functionally complete, and it has free assemblers and simulators  
available (not to mention that it's used to teach basic architecture  
and tools at a number of universities).

If you think this would be useful let me know and I can commit back  
to the repo sooner rather than later.
