--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced testcase [without includes] (which also fails with SSE and on aarch64):

using V [[gnu::vector_size(16)]] = float;
float f1(float);
float f() {
  const float init[3] = {};
  V v{};
  __builtin_memcpy(&v, init, 3 * sizeof(float));
  return f1(v[0]);
}
