_mm256_lddqu_si256

Moves unaligned integer from memory. The corresponding Intel® AVX instruction is
VLDDQU
.

Syntax

extern __m256i _mm256_lddqu_si256(__m256i const *a);
Arguments
*a
points to a memory location from where unaligned integer value must be moved
Description
Fetches 32 bytes of data, starting at a memory address specified by the
a
parameter, and places them in a destination. This intrinsic calls the corresponding instruction
VLDDQU
, which performs an operation functionally similar to the
VMOVDQU
instruction.
Returns
Result of the move operation.

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. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
