I have an old
computer that was intended to do FFTs. It has a
complete bit order swap, MSB to LSB, instruction.
Well, there's the PowerPC "endian" mode (settable in the MSR)--but
it's
just "sort of"--the little-endian mode simply XORs the lower 3 bits of
the address with 111 (i.e. "flips them").
Or you could use the PowerPC byte-swapped instructions (lwbrx, etc.)
