Function core::arch::x86_64::_mm512_maskz_extractf64x4_pd

pub unsafe fn _mm512_maskz_extractf64x4_pd(
    k: __mmask8, 
    a: __m512d, 
    const IMM8: i32
) -> __m256d

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

Available on x86-64 and target feature avx512f only.

Extract 256 bits (composed of 4 packed double-precision (64-bit) floating-point elements) from a, selected with imm8, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
