/* 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
*
* _mm_mullo_pi16 (x, mmx_constant);
*
* not
*
* _mm_mullo_pi16 (mmx_constant, x);
*
* Also try to minimize dependencies. i.e. when you need a value, try
* to calculate it from a value that was calculated as early as
* possible.
