The "-" after bne is just a hint for the branch prediction mechanism I
believe (the 5th bit in the BO operand). I couldn't figure out why every
other atomic_* function besides atomic decrement has "bne-", but that
shouldn't affect the behavior. I have also tried changing it to "bne-", but
it has no effect.
