Intel® Streaming SIMD Extensions 2 (Intel® SSE2) intrinsics for integer shift operations are listed in this topic. The prototypes for Intel® SSE2 intrinsics are in the
To use these intrinsics, include the
immintrin.hfile as follows:
The results of each intrinsic operation are placed in registers. The information about what is placed in each register appears in the tables below, in the detailed explanation of each intrinsic.
R7represent the registers in which results are placed.
countargument is one shift count that applies to all elements of the operand being shifted. It is not a vector shift count that shifts each element by a different amount.
