# 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

# fill value between independantly viable peices of code, it should
