std::experimental::simd<T,Abi>::copy_to
From cppreference.com
template< class U, class Flags >
void copy_to( U* mem, Flags flags );
|
(parallelism TS v2) | |
The store function copies all elements of a simd such that the i-th element is converted to U and subsequently written to mem[i] for all i in the range of [0, size()).
Parameters
| mem | - | a pointer into an array where [mem, mem + size()) is a valid range
|
| flags | - | if of type vector_aligned_tag, the load constructor may assume mem to point to storage aligned by memory_alignment_v<simd, U>
|
| Type requirements | ||
-U must be a vectorizable type.
| ||
-is_simd_flag_type_v<Flags> must be true.
| ||
Example
Run this code
#include <experimental/simd>
#include <iostream>
namespace stdx = std::experimental;
int main()
{
alignas(stdx::memory_alignment_v<stdx::native_simd<int>>)
std::array<int, stdx::native_simd<int>::size()> mem = {};
stdx::native_simd<int> a = 7;
a.copy_to(&mem[0], stdx::vector_aligned);
for (int e : mem)
std::cout << e << ' ';
std::cout << '\n';
}
Possible output:
7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7
