std::experimental::simd_mask<T,Abi>::size
From cppreference.com
static constexpr size_t size() noexcept;
|
(parallelism TS v2) | |
Returns the width (the number of values) of simd_mask<T, Abi>.
Example
The actual output depends on target and compiler flags.
Run this code
#include <experimental/simd>
#include <iostream>
namespace stdx = std::experimental;
int main()
{
stdx::native_simd_mask<int> a { true };
std::cout << a.size() << '\n';
std::cout << popcount(a) << '\n';
}
Possible output:
16
16
