The prototypes for MMX™ technology intrinsics are in the mmintrin.h header file.
For detailed information about an intrinsic, click on that intrinsic in the following table.
| Intrinsic Name |
Operation | Corresponding MMX Instruction |
|---|---|---|
| _mm_and_si64 | Bitwise AND | PAND |
| _mm_andnot_si64 | Bitwise ANDNOT | PANDN |
| _mm_or_si64 | Bitwise OR | POR |
| _mm_xor_si64 | Bitwise Exclusive OR | PXOR |
__m64 _mm_and_si64(__m64 m1, __m64 m2)
Perform a bitwise AND of the 64-bit value in m1 with the 64-bit value in m2.
__m64 _mm_andnot_si64(__m64 m1, __m64 m2)
Perform a bitwise NOT on the 64-bit value in m1 and use the result in a bitwise AND with the 64-bit value in m2.
__m64 _mm_or_si64(__m64 m1, __m64 m2)
Perform a bitwise OR of the 64-bit value in m1 with the 64-bit value in m2.
__m64 _mm_xor_si64(__m64 m1, __m64 m2)
Perform a bitwise XOR of the 64-bit value in m1 with the 64-bit value in m2.
