_mm512_undefined_pd in core::arch::x86 - Rust
Description: Returns vector of type `__m512d` with indeterminate elements. Despite using the word “undefined” (following Intel’s naming scheme), this non-deterministically picks some valid value and is not equivalent to `mem::MaybeUninit`. In practice, this is typically equivalent to `mem::zeroed`.
