Function core::arch::x86::_mm512_maskz_extracti64x4_epi64

pub unsafe fn _mm512_maskz_extracti64x4_epi64(
    k: __mmask8, 
    a: __m512i, 
    const IMM1: i32
) -> __m256i

🔬 This is a nightly-only experimental API. (stdsimd #48556)

This is supported on x86 and target feature avx512f only.

Extract 256 bits (composed of 4 packed 64-bit integers) from a, selected with IMM1, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
