Issue with __m256 type of intel intrinsics

Question

I\'m trying to test some of the Intel Intrinsics to see how they work. So, i created a function to do that for me and this is the code:

void test_intel_256()         


        

Answer 1

try this out

res=_MM_ADD_PS(vec1,vec2); because the prototype of the __M256_MM_ADD_PS is

__m256 _MM_ADD_PS(__m256,__m256);

it takes two __m256 data types as the parameters and returns their sum as __m256 data, just like

int add(int , int);

for initializing

vec=_MM_setr_PS(7.0,7.0,7.0,7.0,7.0,7.0,7.0,7.0) or

vec =_MM_LOAD_PS(&arr) or

vec =_MM_LOAD_PS(ptr)
