A.5.202 PAND, PANDN: MMX Bitwise AND and AND-NOT
PAND mm1,mm2/m64 ; 0F DB /r [PENT,MMX]
PANDN mm1,mm2/m64 ; 0F DF /r [PENT,MMX]
PAND xmm1,xmm2/m128 ; 66 0F DB /r [WILLAMETTE,SSE2]
PANDN xmm1,xmm2/m128 ; 66 0F DF /r [WILLAMETTE,SSE2]
PAND performs a bitwise AND operation between its two operands (i.e.
each bit of the result is 1 if and only if the corresponding bits of
the two inputs were both 1), and stores the result in the destination
(first) operand.
PANDN performs the same operation, but performs a ones' complement
operation on the destination (first) operand first.
