Function surgeshaper_asym::imports::_mm512_mask_lzcnt_epi64

pub unsafe fn _mm512_mask_lzcnt_epi64(
    src: __m512i, 
    k: u8, 
    a: __m512i
) -> __m512i

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

This is supported with target feature avx512cd only.

Counts the number of leading zero bits in each packed 64-bit integer in a, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
