_mm256_permute2f128_ps

Permutes 128-bit single-precision floating point containing fields into a 256-bit destination vector. The corresponding Intel® AVX instruction is
VPERM2F128
.

Syntax

extern __m256 _mm256_permute2f128_ps(__m256 m1, __m256 m2, int control);
Arguments
m1
a 256-bit float32 source vector
m2
a 256-bit float32 source vector
control
an immediate byte that specifies two 2-bit control fields and two additional bits which specify zeroing behavior.
Description
Permutes 128-bit floating-point-containing fields from the first source vector
m1
and second source vector
m2
, by using bits in the 8-bit
control
argument.
Returns
A 256-bit float32 vector with permuted values.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
