--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed, the constant initializer doesn't inherit the alignment. But it
works for the following for example where with -O -mavx512 we output
an aligned load and _do_ align the initializer. So, are you requesting
the initializer honor the targets alignment?
typedef int v4si __attribute__((vector_size(64)));
int bar (v4si v);
int foo (int i)
{
int a_1[131] __attribute__((aligned(64))) = {38580, 691093, 378582, 691095,
