Hi!


In answer to both your questions, I hope: ideally, intermediate
representations should not be at all machine dependent (beyond the fact that
they might be dependent on, say, the Von Neumann architecture). When I think
of intermediate code, I think of something along the lines of P-code (by
Wirth), which is a sort of machine code for a simple, hypothetical,
stack-based machine, and is quite generic and non-machine-dependent. That
might be a good one for your purposes. By the way, could you (or a
colleague) suggest a good book or reference on such back-end compiler
optimization?


Thanks and good luck...
