Microsoft Specific
Provides a way to initialize the two 64-bit elements of the __m128i structure with two identical integers.
__m128i _mm_set1_epi64x(
__int64 i
);
Parameters
- [in] i
A 64-bit integer to use to initialize the result.
Return Value
An __m128i structure whose two 64-bit integer members are initialized with the input parameter.

Remarks
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.
Example
// _mm_set1_epi64x.cpp
// processor: x64
#include <intrin.h>
#include <stdio.h>
#pragma intrinsic(_mm_set1_epi64x)
int main()
{
__m128i c;
__int64 a = 2;
c = _mm_set1_epi64x(a);
printf_s("%I64d %I64d\n", c.m128i_i64[0], c.m128i_i64[1]);
}
