Function core::arch::x86::_mm_maskz_lzcnt_epi32

pub unsafe fn _mm_maskz_lzcnt_epi32(k: __mmask8, a: __m128i) -> __m128i

🔬This is a nightly-only experimental API. (stdsimd #48556)

Available on (x86 or x86-64) and target feature avx512cd,avx512vl and x86 only.

Counts the number of leading zero bits in each packed 32-bit integer in a, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
