no.

yes please

track the file (which is missing), back to microwatt, then make it. in this
case it's made simply with "make" in the microwatt/tests/decrementer
subdirectory.  from that it should be fairly obvious what needs to be done
when modifying sim.py to run other tests (cd microwatt/tests/xics; make).

all of this needs to be "de-hack-i-fied" and put into a proper Makefile,
the hack-the-source option replaced with a command-line option etc. etc.
etc.

therefore I think it would be worthwhile for me to document the full

or whatever, yes.

Do you think it would be worthwhile for me to document the full

yes, probably a good idea.

As of right now we don't document microwatt as a

tck, tck, *thinks*... yes.  separate subject.  although, i am not hugely
keen on the idea of trying to use a mailing list as an "editable document
store" i don't expect there to be multiple revisions.  it's just an
introductory message.
