#48556)Available on (x86 or x86-64) and target feature
avx512cd,avx512vl
and x86 only.Expand description
Counts the number of leading zero bits in each packed 32-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).
