_mm256_hadd

Adds horizontal pairs of float32 elements of two vectors. The corresponding Intel® AVX instruction is VHADDPS.

Syntax

extern __m256 _mm256_hadd_ps(__m256 m1, __m256 m2);

Arguments

`m1`	float32 vector used for the operation
`m2`	float32 vector also used for the operation

Description

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

Returns the result of the addition operation.
