Okay - I was trying to understand if there was some sort of IR 
that is intermediate stage before codegen - but I couldn't see 
this. Also the code is quite hard to follow without enough 
documentation of what's going on. Plus lots of global state I 
think which is fine for a command line tool but not a JIT engine. 
But really I looked only for a short while so please correct me 
if I am wrong.

I decided to use a cut-down version of Eclipse OMR - the backend 
is much smaller than LLVM, although not as small as I would like. 
But I hope to create a more trimmed version in due course.
