Overview: Floating-point Memory and Initialization Operations for Streaming SIMD Extensions 2

This section describes the load, set, and store operations, which let you load and store data into memory. The load and set operations are similar in that both initialize __m128d data. However, the set operations take a double argument and are intended for initialization with constants, while the load operations take a double pointer argument and are intended to mimic the instructions for loading data from memory. The store operation assigns the initialized data to the address.

Note

There is no intrinsic for move operations. To move data from one register to another, a simple assignment, A = B, suffices, where A and B are the source and target registers for the move operation.

The prototypes for Streaming SIMD Extensions 2 (SSE2) intrinsics are in the emmintrin.h header file.
