/* __builtin_apply_args () and __builtin_return () built-in functions does
2
   not function properly when -mmmx is used in compile flags.
3
   __builtin_apply_args () saves all registers that pass arguments to a
4
   function, including %mm0-%mm3, to a memory block, and __builtin_return ()
5
   restores %mm0, from a return memory block, as it can be used as a
6
   function return register.  Unfortunatelly, when MMX registers are touched,
7
   i387 FPU switches to MMX mode, and no FP operation is possible until emms
8
   instruction is issued.  */
