Most of the existing Graal unit tests don't (or shouldn't) produce output on the console (apart from that generated by Junit itself). It would be great if the simulator could be made to do the same somehow.

That is a very good point.  Having a simulator written in Java for all GPU architectures we support would be a major help to keep the compilers up and running and not break anything.  We've seen how bit-rot can easily happen with things like the Zero or Shark ports.
