Hi Denis,
I'd like to know whether there is something new about the (cc0) issue:
I'd like to proceed with splitting the patterns for move, plus, minus and
multiply. Since some of the operations will 1.) will need to communicate that
they use the carry flag for intermediate results and 2.) will have to
communicate that they will leave the condition code with useful values, I did
not work on them so far: I would need to know how the CCmode conversion
should look like.
Yours,
Björn
