Thanks for the tip, so I remove this from my short list.

I also had an eye on this tutorial. It seems to go to extensive detail  
for a backend of the "CPU0" architecture which appears to be a  
reasonable sample RISC.

PTX is also interesting since it is a close fit due to the fact that  
it is a virtual machine target, as NAC (N-Address Code).
