# 1.27.0[−][src]Function core::arch::x86_64::_mm256_testz_pd

    pub unsafe fn _mm256_testz_pd(a: __m256d, b: __m256d) -> i32

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

Compute the bitwise AND of 256 bits (representing double-precision (64-bit) floating-point elements) in `a` and `b`, producing an intermediate 256-bit value, and set `ZF` to 1 if the sign bit of each 64-bit element in the intermediate value is zero, otherwise set `ZF` to 0. Compute the bitwise NOT of `a` and then AND with `b`, producing an intermediate value, and set `CF` to 1 if the sign bit of each 64-bit element in the intermediate value is zero, otherwise set `CF` to 0. Return the `ZF` value.

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
