# 1.27.0[−][src]Function core::arch::x86_64::_mm256_testc_si256

    pub unsafe fn _mm256_testc_si256(a: __m256i, b: __m256i) -> i32

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

Computes 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. Computes 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 `CF` value.
