/* __builtin_apply_args () and __builtin_return () built-in functions does

   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

   instruction is issued.  */
