Even further reduced (-g -O2):

union U

{

  float f;

  int i;

};



void

foo (unsigned short *x, unsigned char y)

{

  unsigned char g;

  union U u;

  if (u.i < 0)

    g = 0;

  else

    {

      u.f = u.f * (255.0F / 256.0F) + 32768.0F;

      g = (unsigned char) u.i;

    }

  *x = (g << 8) | y;

}
