Function creusot_contracts::std::arch::x86_64::_mm512_mask_extracti64x4_epi64

pub unsafe fn _mm512_mask_extracti64x4_epi64<const IMM1: i32>(
    src: __m256i,
    k: u8,
    a: __m512i,
) -> __m256i

🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Available on x86-64 only.

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