You should look at the bc (Branch Conditional) Instruction page,
http://publib.boulder.ibm.com/infocenter/systems/index.jsp?topic=/com.ibm.aix.aixassem/doc/alangref/bc.htm&tocNode=int_13023
again.  The BO field for processors compliant with the powerpc architecture
prior to version 2 of the spec ecoded branch hints using a "y" bit.  Later
processors use "at" bits.  gas supports both, but by default selects the older
encoding.  Use -mpower4 (or -mpower5 etc.) to tell gas to use "at" encoding.
