The following four logical-operation intrinsics and their respective instructions are functional as part of Streaming SIMD Extensions 2.
__m128i
_mm_and_si128 ( __m128i a,
__m128i b)
(uses PAND)
Computes the bitwise AND
of the 128-bit value in a
and the 128-bit value in b.
r := a & b
__m128i
_mm_andnot_si128 ( __m128i a,
__m128i b)
(uses PANDN)
Computes the bitwise AND
of the 128-bit value in b
and the bitwise NOT
of the 128-bit value in a.
r := (~a) & b
__m128i
_mm_or_si128 ( __m128i a,
__m128i b)
(uses POR)
Computes the bitwise OR
of the 128-bit value in a
and the 128-bit value in b.
r := a | b
__m128i
_mm_xor_si128 ( __m128i a,
__m128i b)
(uses PXOR)
Computes the bitwise XOR
of the 128-bit value in a
and the 128-bit value in b.
r := a ^ b
