_mm256_blend_ps

Performs a conditional blend/merge of float32 vectors. The corresponding Intel® AVX instruction is
VBLENDPS
.

Syntax

extern __m256 _mm256_blend_ps(__m256 m1, __m256 m2, const int mask);
Arguments
m1
float32 vector used for the operation
m2
float32 vector also used for the operation
mask
a constant of integer type that is the mask for the operation
Description
Performs a conditional merge of eight packed single-precision floating point elements (float32 elements) of two vectors according to the immediate bits of the
mask
parameter.
The
mask
parameter defines a constant integer. The immediate bits [7:0] in the mask determine from which source vector elements are copied into the resulting vector.
If the bits in
mask
are “1” then the corresponding elements of the second source vector are copied into the resulting vector. If the bits are “0” then the corresponding elements of the first source vector are copied into the resulting vector. Thus a merging/blending of the elements of the two source vectors occurs when this intrinsic is used.
Returns
Result of the merge/blend operation.
