Function surge_halfrate::imports::_mm_mask_expand_epi64

pub unsafe fn _mm_mask_expand_epi64(src: __m128i, k: u8, a: __m128i) -> __m128i

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

This is supported with target feature avx512f,avx512vl only.

Load contiguous active 64-bit integers from a (those with their respective bit set in mask k), and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
