_mm256_andnot_si256

Performs bitwise logical AND NOT operation on signed integer vectors. The corresponding Intel® AVX2 instruction is VPANDN.

Syntax

extern __m256i _mm256_andnot_si256(__m256i s1, __m256i s2);

Arguments

s1

signed integer vector used for the operation

s2

signed integer vector also used for the operation

Description

Performs a bitwise logical NOT operation on source vector s1 then performs bitwise AND with source vector s2 and stores the result in the destination vector. If the corresponding bit in the first vector is 0 and the corresponding bit in the second vector is 1, each bit of the result is set to 1, otherwise it is set to 0.

Returns

Result of the bitwise logical AND NOT operation.
