Function core::arch::x86_64::_mm256_testz_si256

pub unsafe fn _mm256_testz_si256(a: __m256i, b: __m256i) -> i32

This is supported on x86-64 and target feature avx only.

Compute the bitwise AND of 256 bits (representing integer data) in a and b, and set ZF to 1 if the result is zero, otherwise set ZF to 0. Compute the bitwise NOT of a and then AND with b, and set CF to 1 if the result is zero, otherwise set CF to 0. Return the ZF value.
