PXOR

_mm_and_si64

__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.

_mm_andnot_si64

__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.

_mm_or_si64

__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.

_mm_xor_si64

__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.
