NAME¶

std::experimental::simd_abi::max_fixed_size - std::experimental::simd_abi::max_fixed_size

Synopsis¶

Defined in header <experimental/simd>
template< class T >
inline constexpr int max_fixed_size = (parallelism 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
