template<class T> constexprint max_fixed_size=/*implementation-defined*/; | (parallelism TS v2) | |
The value ofmax_fixed_size<T> declares that an instance ofsimd<T, fixed_size<N>> withN<= max_fixed_size<T> is supported by the implementation. The value ofmax_fixed_size<T> is at least32.
It is unspecified whether an implementation supportssimd<T, fixed_size<N>> withN> max_fixed_size<T>. The value ofmax_fixed_size<T> may depend on compiler flags and may change between different compiler versions.
#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<longdouble><<'\n';}
