- 在调用always_inline ' _mm_mullo_epi32 '时，内联失败:目标特定选项不匹配1的答案。
I am trying to compile this project from github which is implemented in C++ with SIMD intrinsic (SSE4.1). The project in github is given as a Visual Studio solution, but I am trying to port it in Qtcreator with cmake. While I am trying to compile it I get the following error:
我试图从github上编译这个项目，它是用c++实现的，SIMD内部(SSE4.1)。github中的项目是一个Visual Studio解决方案，但是我尝试用cmake将它导入Qtcreator。当我试图编译它时，我得到了以下错误:
/usr/lib/gcc/x86_64-unknown-linux-gnu/5.3.0/include/smmintrin.h:520:1: error: inlining failed in call to always_inline '__m128i _mm_cvtepu8_epi32(__m128i)': target specific option mismatch
_mm_cvtepu8_epi32 (__m128i __X)
which I am sure it has to do with the SSE optimization part, but since I am not that familiar with this subject I do not really know what it means and how I can solve it and in the net that I searched I couldn't really get something useful. The code that gives the following problem is the following:
我确信它与SSE优化部分有关，但由于我对这个主题不熟悉，所以我不知道它的含义，也不知道如何解决它，在我搜索的网络中，我找不到有用的东西。给出以下问题的代码如下:
static void cvt8u32f(const Mat& src, Mat& dest, const float amp)
{
const int imsize = src.size().area()/8;
const int nn = src.size().area()- imsize*8 ;
uchar* s = (uchar*)src.ptr(0);
float* d = dest.ptr<float>(0);
const __m128 mamp = _mm_set_ps1(amp);
const __m128i zero = _mm_setzero_si128();
for(int i=imsize;i--;)
{
__m128i s1 = _mm_loadl_epi64((__m128i*)s);
_mm_store_ps(d,_mm_mul_ps(mamp,_mm_cvtepi32_ps(_mm_cvtepu8_epi32(s1))));
_mm_store_ps(d+4,_mm_mul_ps(mamp,_mm_cvtepi32_ps(_mm_cvtepu8_epi32(_mm_srli_si128(s1,4)))));
s+=8;
d+=8;
}
for(int i=0;i<nn;i++)
{
*d = (float)*s * amp;
s++,d++;
}
}
can someone explain me what is the issue and what I am missing. Thanks in advance.
有人能给我解释一下这个问题是什么吗?提前谢谢。
