Me too. I assume you will replace it by true eight bit arithmetic? Since we don't live in an ideal world we have to stick with mint8 for a while. If you care to complete reading my original post you will see that this has nothing to with the usual complaints about mint8, most of which i am aware of. The problem i am pointing out can (easily) be solved by letting gcc emit only positive/hexadecimal operands or by a minimal change in the way the cbr instruction calculates its operand: (0xFF-x) -> (0xFF - (x & 0xFF)). If you do not care to read it to the end, well, in any case it is known from know on, that you cannot use the cbr instruction reliably with mint8.
