If
is_simd_mask_v<T>
is
true
and
U
is
bool
, or if
is_simd_v<T>
is
true
and
U
is a vectorizable type, provides the member constant
value
equal to the minimum alignment of a pointer passed to a load constructor,
copy_from
function, or
copy_to
function. For any other types
T
and
U
, there is no member
value
.
If the program adds specializations for
std::memory_alignment
or
std::memory_alignment_v
(since C++17)
, the behavior is undefined.
