Reduced C code is

int rl2_decode_png_bit_depth;
int *rl2_decode_png_p_data;
void rl2_decode_png_row_pointers() {
  unsigned sample_type =3D 0;
  _setjmp();
  switch (rl2_decode_png_bit_depth)
  case 6:
    sample_type =3D 7;
  png_destroy_read_struct();
  for (;;)
    switch (sample_type)
    case 3:
    case 5:
      *rl2_decode_png_p_data;
