   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.
