Strange, wonder how I've missed this.
I guess easiest would be probably just to
if (!TARGET_AVX2)
{
struct expand_vec_perm_d d_copy = *d;
d_copy.target = gen_lowpart (V{4DF,8SF}mode, d->target);
d_copy.op0 = gen_lowpart (V{4DF,8SF}mode, d->op0);
d_copy.op1 = gen_lowpart (V{4DF,8SF}mode, d->op1);
return expand_vec_perm_even_odd_1 (&d_copy);
}
for V{4DI,8SI}mode. Or if (!TARGET_AVX2) return false;.
