This overload is also not really expected to be called directly but only by the other overload which already has the static_assert. And the equivalent overload for A/B also don't have the static_assert

For A & B, CopyOp can be void, so they don't need a corresponding assert

return make_block_2d_copy_CD<ValType>(op, mma, gstride, find_x_mode(gstride), find_y_mode(gstride));
}
