Why? Too lazy to find the lastest docs?

I asume that the endian flag is for SIMD.
One other problem with SIMD is that I asume it is for
just operations with simple register indirect addressing.
*a=*a op *b;a++;b++;
If you need anything else you have to go back to
normal processing. This limits the what you can do
as you want to have orthagonal processing ability on
SIMD.
