If
T
is a vectorizable type and
is_abi_tag_v
<
Abi
>
is
true
, provides the member constant
value
equal to the width (number of elements) of
simd
<
T, Abi
>
, irrespective of whether
simd
<
T, Abi
>
is supported or not. For any other types
T
and
Abi
, there is no member
value
.
If the program adds specializations for
std::simd_size
or
std::simd_size_v
(since C++17)
, the behavior is undefined.
