Store Intrinsics

The prototypes for Intel® Streaming SIMD Extensions (Intel® SSE) intrinsics for store operations are in the
xmmintrin.h
header file.
To use these intrinsics, include the
immintrin.h
file as follows:
#include <immintrin.h>
The description for each intrinsic contains a table detailing the returns. In these tables, p[
n
] is an access to the
n
element of the result.
Intrinsic Name
Operation
Corresponding
Intel® SSE Instruction
_mm_storeh_pi
Store high
MOVHPS mem, reg
_mm_storel_pi
Store low
MOVLPS mem, reg
_mm_store_ss
Store the low value
MOVSS
_mm_store1_ps

Shuffling + MOVSS
_mm_store_ps
