Sorry to mess you around, but I thought David was objecting more to the
macro existing at all.  I could be wrong though.

The problem with using ufr for disassembly is that AFAICT it isn't
mentioned in the manuals.  People disassembling pass-me-downs might
struggle to know what it means.  Maybe the ideal would be to disassemble
the CTC1 normally and add a comment "; ufr [01]" next to it.  But that's
probably make-work.

So TBH I preferred your original patch.

There haven't been any more objections, so if you're still OK with the
original version, I suggest we go with that.  I can apply it for you if so.

Thanks,
Richard
