(parallelism TS v2) | |
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.
The behavior of a program that adds specializations for std::simd_size or std::simd_size_v (since C++17) is undefined.
