Unfortunately there is # no symmetrical mcore opcode that functions as a noop. The # chosen solution is to use "tst r0, r14". This is a symetrical # value, and apart from the corruption of the C bit, it has no other # side effects. Since the carry bit is never tested without being # explicitly set first, and since the NOP code is only used as a # fill value between independantly viable peices of code, it should # not matter.
