Thanks, I will take a look at Bernd's work. IIRC, he took a
different approach from what was suggested in the wiki, right?
Yes, let's say that it's a half-baked conversion, probably a consequence of
the bounty. This might be good enough, depending on the architecture.
I very much disagree with this. I think my approach was possibly the
only viable one, and definitely the most sensible one for this target.
Not only is there nothing meaningful to be gained from separating cc
setters and users on m68k given that almost all instructions (including
moves) clobber the flags, it is not really an actively maintained target
and any more adventurous approach would have introduced many more
possibilities for error. Generating exactly the same code as before as
much as possible was the correct goal IMO.
