std::experi...x_fixed_size(3) C++ Standard Libary std::experi...x_fixed_size(3) NAME std::experimental::simd_abi::max_fixed_size - std::experimen- tal::simd_abi::max_fixed_size Synopsis Defined in header <experimental/simd> template< class T > inline constexpr int max_fixed_size = (paral- lelism TS v2) /*implementation-defined*/; The value of max_fixed_size<T> declares that an instance of simd<T, fixed_size<N>> with N <= max_fixed_size<T> is supported by the implementation. The value of max_fixed_size<T> is at least 32. Notes It is unspecified whether an implementation supports simd<T, fixed_size<N>> with N > max_fixed_size<T>. The value of max_fixed_size<T> may depend on compiler flags and may change between different compiler versions. Example // Run this code #include <cstdint> #include <experimental/simd> #include <iostream> namespace stq = std::experimental; int main() { std::cout << stq::simd_abi::max_fixed_size<std::uint8_t> << ' '; std::cout << stq::simd_abi::max_fixed_size<std::uint64_t> << ' '; std::cout << stq::simd_abi::max_fixed_size<float> << ' '; std::cout << stq::simd_abi::max_fixed_size<long double> << '\n'; } Possible output: 32 32 32 32 See also fixed_size tag type for storing specified number of elements (parallelism TS v2) (alias template) http://cppreference.com 2024.06.10 std::experi...x_fixed_size(3)
