--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I suspect this is almost the same issue as reported in PR 104450 or very
similar.

The IR in GCC 10 before veclowering:
  _5 = _2 < _3;

  <bb 3> :
  _4 = VEC_COND_EXPR <_5, { -1, -1, -1, -1 }, { 0, 0, 0, 0 }>;

While the IR in GCC 11:
  _4 = _2 < _3;

  <bb 3> :
  _5 = _4;
  _6 = VEC_COND_EXPR <_5, { -1, -1, -1, -1 }, { 0, 0, 0, 0 }>;

Notice the extra assignment. It is just hiding the issue.
