Returns the __m128i structure with its two 64-bit integer values initialized to the values of the two 64-bit integers passed in.

__m128i _mm_set_epi64x( 
   __int64 i1 
...__int64 i2 

[in] i1

A 64-bit integer to place in the second position of the result.

[in] i2

A 64-bit integer to place in the first position of the result.

An __m128i structure containing two 64-bit integers composed of the input parameters.





Header file <intrin.h>

Because the __m128i structure represents an XMM register, this intrinsic provides a way of writing values from system memory to the XMM registers.

This routine is only available as an intrinsic.

// _mm_set_epi64x.cpp
// processor: x64
#include <intrin.h>
#include <stdio.h>

#pragma intrinsic(_mm_set_epi64x)

int main()
    __m128i c;
    __int64 a = 2, b = 54;

    c = _mm_set_epi64x(a, b);

    printf_s("%I64d %I64d\n", c.m128i_i64[0], c.m128i_i64[1]);
