+ not function properly when -mmmx is used in compile flags.
+ __builtin_apply_args () saves all registers that pass arguments to a
+ function, including %mm0-%mm3, to a memory block, and __builtin_return ()
+ restores %mm0, from a return memory block, as it can be used as a
+ function return register. Unfortunatelly, when MMX registers are touched,
+ i387 FPU switches to MMX mode, and no FP operation is possible until emms
