--- Comment #1 from Drea Pinski <pinskia at gcc dot gnu.org> ---
Before veclowering:
_4 = g26_lsm.9_22 == { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };
_5 = VEC_COND_EXPR <_4, { 4294967295, 4294967295, 4294967295, 4294967295,
4294967295, 4294967295, 4294967295, 4294967295, 4294967295, 4294967295,
4294967295, 4294967295, 4294967295, 4294967295, 4294967295, 4294967295 }, { 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }>;
After:
_6 = {_44, _38, _32, _37, _53, _59, _65, _71, _77, _83, _89, _95, _101, _107,
_113, _119};
_120 = g26_lsm.9_22 != { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };
So it is not lowering it ...
