--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed. The code generation out of the gimple is basically the same as what
is done for PR 113857.  

FAIL: gcc.target/aarch64/pr109072_1.c check-function-bodies s16x4_2

vector(4) short int _9;

  <bb 2> [local count: 1073741824]:
  _9 = {x_2(D), 0, 0, 0};


XPASS: gcc.target/aarch64/pr109072_1.c check-function-bodies s64x2_2


XFAIL: gcc.target/aarch64/pr109072_1.c check-function-bodies s32x4_2
  vector(4) int _9;

  <bb 2> [local count: 1073741824]:
  _9 = {x_2(D), 0, 0, 0};
  return _9;

So this depends on PR 113857
