2 #
3 # Bit operation instructions \(BCLR, BNOT, BSET, BTST\) should not be placed in IU.
4 # If the user specifically indicates they should be in the IU, GAS will
5 # generate warnings. The reason why this is not an error is that those instructions
6 # will fail in IU only occasionally. Thus GAS should pack them in MU for
7 # safety, and it just needs to draw attention when a violation is given.
