Like Michael said, avoid doing the call yourself at all cost. From the
looks of it, you can just write in C:
score2 = ff_hf_noise16_mmx(pix1, line_size, h) +
ff_hf_noise8_mmx(pix1+8, line_size, h)
            - ff_hf_noise16_mmx(pix2, line_size, h) -
ff_hf_noise8_mmx(pix2+8, line_size, h);

Or something.
