I think you're right, I am not familiar coldfire assembly and
instruction. I just touched it no long time.
addqb instruction is not supported on coldfire platform.
Which better way to replace it? I tried to use addql, but it proves that
it's incorrect.
I guess my patch could be better way to replace it now.

Lanttor
