Purpose:
Bitwise ternary logic that provides the capability to implement any three-operand binary function; the specific binary function is specified by value in "imm8". For each bit in each packed 32-bit integer, the corresponding bit from "a", "b", and "c" are used to form a 3 bit index into "imm8", and the value at that bit in "imm8" is written to the corresponding bit in "dst" using zeromask "k" at 32-bit granularity (32-bit elements are zeroed out when the corresponding mask bit is not set).
Result:
__m256i
Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
__m256i a = _mm256_set_epi32(0xFFFFFFFF, 0, 0xFFFFFFFF, 0, 0xFFFFFFFF, 0, 0xFFFFFFFF, 0);
__m256i b = _mm256_set_epi32(0xAAAAAAAA, 0xAAAAAAAA, 0xAAAAAAAA, 0xAAAAAAAA, 0xAAAAAAAA, 0xAAAAAAAA, 0xAAAAAAAA, 0xAAAAAAAA);
__m256i c = _mm256_set_epi32(0x55555555, 0x55555555, 0x55555555, 0x55555555, 0x55555555, 0x55555555, 0x55555555, 0x55555555);
__mmask8 k = 0xF0;
__m256i result = _mm256_maskz_ternarylogic_epi32(k, a, b, c, 0x96);
int* res = (int*)&result;
for (int i = 0; i < 8; i++)
printf("%08X\n", res[i]);
return 0;
