Intel® C++ Compiler XE 13.1 User and Reference Guides
Adds horizontal pairs of float32 elements of two vectors. The corresponding Intel® AVX instruction is VHADDPS.
extern __m256 _mm256_hadd_ps(__m256 m1, __m256 m2); |
m1 |
float32 vector used for the operation |
m2 |
float32 vector also used for the operation |
Performs a SIMD addition of adjacent (horizontal) pairs of single-precision floating-point elements (float32 elements) in the first source vector m1 with adjacent pairs of float32 elements in the second source vector m2.
Returns the result of the addition operation.
