--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
  # RANGE [irange] int [-536870912, -8][1, 16]
  # lane_size_6 = PHI <1(2), lane_size_12(8)>
  # RANGE [irange] unsigned int [1, 5]
  # ivtmp_20 = PHI <5(2), ivtmp_21(8)>
  # RANGE [irange] unsigned int [0, 4]
  ivtmp_21 = ivtmp_20 + 4294967295;

lane_size_12 is just 1<<ivtmp_21 so I don't see where the [-536870912, -8] is
coming from.
