/* Notes about writing mmx code
*
* give memory operands as the second operand. If you give it as the
* first, gcc will first load it into a register, then use that register
*
* ie. use
*
* __builtin_pmullw (x, mmx_constant[8]);
*
* not
*
* __builtin_pmullw (mmx_constant[8], x);
*
* Also try to minimize dependencies. Ie. when you need a value, try to calculate
