Function tract_hir::internal::tract_downcast_rs::__std::arch::x86_64::_mm512_maskz_insertf64x4

pub unsafe fn _mm512_maskz_insertf64x4(
    k: u8, 
    a: __m512d, 
    b: __m256d, 
    imm8: i32
) -> __m512d

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

This is supported on x86-64 and target feature avx512f only.

Copy a to tmp, then insert 256 bits (composed of 4 packed double-precision (64-bit) floating-point elements) from b into tmp at the location specified by imm8. Store tmp to dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
