Other than that: To convert a port, there is still a lot of work to be
done to define and handle the various CC modes properly (well, not for
the pdp11, because it writes out >1 insn for most define_insns), but
it is great not having to define all the pairs of clobber-flags and
set-flags insns.  At least, I didn't end up rewriting the complete .md
file. It was relatively easy. Less book-keeping involved, etc.

And where's the patch? :)
