Not sure what you mean by "exactly", but it works. Even as per
the documentation! See src/sim/cris and src/cpu/cris.cpu.

Judging from the documentation, I guess the "only" refers to the
CGEN-SID delay support. If the latter, I don't mind very much
changing the port, if there can be sim support as well (Someone
writing it, or perhaps Someone handholding me through
implementing it), or (worse) some test-conditional applicable
for defining a pmacro with differing contents (see
src/cpu/mt.cpu:dset).
