Function core::arch::x86_64::_mm256_maskz_lzcnt_epi32

pub unsafe fn _mm256_maskz_lzcnt_epi32(k: __mmask8, a: __m256i) -> __m256i

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

This is supported on x86-64 and target feature avx512cd,avx512vl 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).
