| 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. |
