How to convert a hex float to a float in C/C++ using _mm_extract_ps SSE GCC instrinc function

Question

I\'m writing a SSE code to 2D convolution but SSE documentation is very sparse. I\'m calculating dot product with _mm_dp_ps and using _mm_extract_ps to get the dot product

Answer 1

extern void _mm_store_ss(float*, __m128);

See 'xmmintrin.h.'
