------- Comment #6 from pinskia at gcc dot gnu dot org  2005-11-24 20:42 -------
Here is a reduced testcase as far as I can get it:
struct device_driver {
   const char * name;
};
struct video_picture {
   unsigned  short a,b,c,d,e;
};
struct w9968cf_device {
   struct device_driver *driver;
   int vpp_flag;
};
int debug = 2;
int specific_debug = 0;
int w9968cf_set_picture(struct w9968cf_device* cam, struct video_picture pict)
{
   short fmt, reg_v = 0x0000;
   int err = 0;
   long esi, edi;
   switch (fmt)  {
    case 13:
    reg_v |= 0x0002;
   case 4:
   case 5:
     cam->vpp_flag = 8;
   }
   if (err = w9968cf_write_reg(cam, reg_v, 0x16))
     if (err = w9968cf_sensor_update_picture(cam, pict))
        __asm__ __volatile__("movsw"   
:"=&D"(edi),"=&S"(esi):"0"(edi),"1"(esi):"memory");
  if (((specific_debug) && (debug == (1))) || ((!specific_debug) && (debug >=
(1))))
    printk("<4>" "%s %s: " "Failed to change picture settings" "\n" , 
cam->driver->name );
   return err;
}
