This routine is only available as an intrinsic.
Example
// movsq.cpp
// processor: x64
#include <stdio.h>
#include <intrin.h>
#pragma intrinsic(__movsq)
int main()
{
unsigned __int64 a1[10];
unsigned __int64 a2[10] = {950, 850, 750, 650, 550, 450, 350, 250,
150, 50};
__movsq(a1, a2, 10);
for (int i = 0; i < 10; i++)
printf_s("%d ", a1[i]);
printf_s("\n");
