template<class T,class Abi= simd_abi::compatible<T>> struct simd_size; | (parallelism TS v2) | |
IfT is a vectorizable type andis_abi_tag_v<Abi> istrue, provides the member constantvalue equal to the width (number of elements) ofsimd<T, Abi>, irrespective of whethersimd<T, Abi> is supported or not. For any other typesT andAbi, there is no membervalue.
If the program adds specializations forstd::simd_size orstd::simd_size_v(since C++17), the behavior is undefined.
