 >    /* Save the initial rsp */
 >    movq SAVED_RSP,   (0 * CPU_SIZEOF_POINTER)(rsp)
 >  
 > +  /* Save x87 FPU, MMX and SSE state */
 > +.set FXSAVE_SIZE, 512
 > +  /* Make space for FXSAVE */
 > +  subq $FXSAVE_SIZE, rsp
 > +  fwait
 > +  fxsave64 (rsp)
 > +  /* Reset to a clean state */
 > +  fninit
