# [−][src]Function core::arch::x86_64::_mm_maskz_lzcnt_epi64

    pub unsafe fn _mm_maskz_lzcnt_epi64(k: __mmask8, a: __m128i) -> __m128i

🔬 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 64-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).
