The patch is Ok.

I don’t recall a target supports for I/O.  So, I/O is incredible useful.  If you have a simulator, you should take a moment to wire up some IO.  Worst case, you can grab some random instruction, (say svc, trap), and wire in a byte output routine.  Should be just 50 lines of code or so.  This is handy for debugging code on the simulator even if the actual hardware has no way to do I/O.

You should be able to add a target support for io, should only be 10 lines of code or so.


I noticed:

Anyone have a sense of how this is supposed to work and what is wrong?  The lines appear to be the same to me.  :-(

The only thing that might throw it would be the *** EXIT code 0, but, it would seem that wasn’t in the output above.
