--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
Still FAILs to vectorize gcc.dg/vect/pr18425.c with -m32. But we have here
=> get_loop_niters:(unsigned long) (__n_7(D) + 4294967295) + 1
that could have been simplified. __n is unsigned int. So I can special
case that (but really only that ... still common enough).
