--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
One extra case:
typedef int v4si __attribute__((vector_size(16)));
typedef float v4sf __attribute__((vector_size(16)));
v4sf vec_cast1(int *f)
{
return (v4sf){f[0], f[1], f[2], f[3]};
}
In this case, the CONSTRUCTOR is the "store"
