Function creusot_contracts::std::arch::x86_64::_mm256_maskz_lzcnt_epi64

pub unsafe fn _mm256_maskz_lzcnt_epi64(k: u8, a: __m256i) -> __m256i

🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Available on x86-64 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).
