-
- For a normal loop with one addx you set the x-flag correctly like
- this:
-
- moveq #0,d0
- add.l d1,d0
- ...
- .loop addx.l d1,d2
- dbf d7,.loop
-
- But, what we do if we have two addx (16.16 for V too) and still
- want 100% accuracy.
-
- You just cleared the x-flag before the loop, is that really
- correct?
