12 | 3 # Bit operation instructions \(BCLR, BNOT, BSET, BTST\) should not be placed in IU. | |
13 | 4 # If the user specifically indicates they should be in the IU, GAS will | |
14 | 5 # generate warnings. The reason why this is not an error is that those instructions | |
15 | 6 # will fail in IU only occasionally. Thus GAS should pack them in MU for | |
16 | 7 # safety, and it just needs to draw attention when a violation is given. | |
