--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
  # RANGE [irange] unsigned long [8, +INF] MASK 0xfffffffffffffff8 VALUE 0x0
  _21 = (unsigned long) &sD.2327;
  # RANGE [irange] unsigned long [0, 0][8, 47][49, +INF] MASK
0xfffffffffffffff8 VALUE 0x0
  ivtmp.16_20 = _21 + 48;

vs
  # RANGE [irange] unsigned long [8, +INF] MASK 0xfffffffffffffff8 VALUE 0x0
  ivtmp.16_20 = (unsigned long) &MEM <struct S[50]> [(voidD.45 *)&sD.2292 +
48B];
