_mm_cmpunord_ss in core::arch::x86_64 - Rust
Description: Checks if the lowest `f32` of both inputs are unordered. The lowest 32 bits of the result will be `0xffffffff` if any of `a.extract(0)` or `b.extract(0)` is a NaN, or `0` otherwise. The upper 96 bits of the result are the upper 96 bits of `a`.
