_mm256_addsub_ps

Adds odd float32 elements and subtracts even float32 elements of vectors. The corresponding Intel® AVX instruction is
VADDSUBPS
.

Syntax

extern __m256 _mm256_addsub_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 the odd single-precision floating-point elements (float32 elements) in the first source vector
m1
with the odd float32 elements in the second source vector
m2
.
Simultaneously, the intrinsic performs subtraction of the even single-precision floating-point elements (float32 elements) in the second source vector,
m2
, from the even float32 elements in the first source vector,
m1
.
Returns
Result of the operation stored in the result vector.
