<span class='option'>_mm256_xor_si256</span>

Performs bitwise logical XOR operation on signed integer vectors. The corresponding Intel® AVX2 instruction is VPXOR.

Syntax

extern __m256i _mm256_xor_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 XOR operation of the signed integer elements of source vector s2 and the corresponding elements in source vector s1 and stores the result in the destination vector. If the corresponding bits of the first and second vectors differ, each bit of the result is set to 1, otherwise it is set to 0.

Returns

Result of the bitwise logical XOR operation.
