示例

  1. 创建testavx.cpp文件，文件内容如下。

    #include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
#include "avx2ki.h"
#include "operatoroverload.h"

void OperatorExample()
{
    int64_t a[2] = {-5, 13};
    int64_t b[2] = {12, 3};
    int64_t c[2] = {0};
    __m128i t1 = _mm_load_epi64(a);
    __m128i t2 = _mm_load_epi64(b);
    __m128i dst = t1 + t2;
    _mm_store_epi64(c, dst);
    printf("dst: %ld %ld\n", c[0], c[1]);
}

int main(void) {
    OperatorExample();
    return 0;
}

  2. 编译。

    g++ testavx.cpp -o testavx -I/usr/local/ksl/include -L/usr/local/ksl/lib -lavx2ki
    运行结果：
    1
    dst: 7 16
