Function _mm_undefined_ph

pub fn _mm_undefined_ph() -> __m128h

🔬This is a nightly-only experimental API. (stdarch_x86_avx512_f16 #127213)

Available on (x86 or x86-64) and target feature avx512fp16,avx512vl and x86-64 only.

Return vector of type __m128h with indetermination 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.
