Logical Intrinsics

The prototypes for Intel® Streaming SIMD Extensions (Intel® SSE) intrinsics for logical operations are in the
xmmintrin.h
header file.
To use these intrinsics, include the
immintrin.h
file as follows:
#include <immintrin.h>
The results of each intrinsic operation are placed in a register. This register is illustrated for each intrinsic with R0-R3. R0, R1, R2, and R3 each represent one of the four 32-bit pieces of the result register.
