--- Comment #2 from David Binderman <dcb314 at hotmail dot com> ---
Reduced C code seems to be:

int g_29, func_47_p_48, func_47_p_51_l_129;
void func_47_p_51() {
  for (;;) {
    func_47_p_51_l_129 = 0;
    for (; func_47_p_51_l_129 <= 1; func_47_p_51_l_129 += 1) {
      short *l_160 = func_47_p_48 || *l_160;
      *l_160 &= g_29;
    }
  }
}
