Otherwise it will do the reverse in the register. The new (Cell only) double word byte-reversed instructions support has not been added to GCC yet though. I will get on to adding it when I get some time :). -- Pinski Alex,

My code just calls <code>bswap_16</code> and friends in the swapped case; on the i386 using glibc that will generate an rorw instruction.
