C ++的错误：“_mm_sin_ps”在此范围内未声明C ++的错误：“_mm_sin_ps”在此

我想测试不同的方式给一个函数应用于阵列。

为什么https://software.intel.com/sites/landingpage/IntrinsicsGuide/#expand=3260,2124,4779,4779&cats=Trigonometry&text=_sin

_mm_sin_ps不知道我的范围，但_mm_sqrt_ps是什么？

我怎么让他们知道？并编译它没有错误。

    const int T1=4E6;

        {
            array[T]=dis(gen);
        }

            __m128 result = _mm_sin_ps(X);
            _mm_storeu_ps(it, result);
            it+=4;
        }

_mm_sin_ps是部分SVML库，随只有英特尔的编译器。 GCC开发者专注于包装机器指令和简单的任务，所以有中没有SVML immintrin.h为止。

你必须使用一个库或自己写。窦实现：
