The prototypes for Streaming SIMD Extensions 2 (SSE2) intrinsics are in the emmintrin.h header file.
For detailed information about an intrinsic, click on that intrinsic name in the following table.
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. R0 and R1 represent the registers in which results are placed.
| Intrinsic Name |
Operation |
Corresponding SSE2 Instruction |
|---|---|---|
| _mm_and_pd | Computes AND | ANDPD |
| _mm_andnot_pd | Computes AND and NOT | ANDNPD |
| _mm_or_pd | Computes OR | ORPD |
| _mm_xor_pd | Computes XOR | XORPD |
__m128d _mm_and_pd(__m128d a, __m128d b)
Computes the bitwise AND of the two DP FP values of a and b.
| R0 | R1 |
