The PAND (Bitwise Logical And), PANDN (Bitwise Logical And Not), POR (Bitwise Logical OR), and PXOR (Bitwise Logical Exclusive OR) instructions perform bitwise logical operations on 64-bit quantities. The destination operand is an MMX register, while the source operand can either be an MMX register or a 64-bit memory operand.

 

DEST ← DEST AND SRC;

DEST ← (NOT DEST) AND SRC;

DEST ← DEST OR SRC;

DEST ← DEST XOR SRC;

PAND __m64 _mm_and_si64 (__m64 m1, __m64 m2)

PANDN __m64 _mm_andnot_si64 (__m64 m1, __m64 m2)

POR __m64 _mm_or_si64(__m64 m1, __m64 m2)

PXOR __m64 _mm_xor_si64 (__m64 m1, __m64 m2)
