Function _mm256_mask_insertf64x2

pub unsafe fn _mm256_mask_insertf64x2<const IMM8: i32>(
    src: __m256d,
    k: u8,
    a: __m256d,
    b: __m128d,
) -> __m256d

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

Available on x86-64 only.

Copy a to tmp, then insert 128 bits (composed of 2 packed double-precision (64-bit) floating-point elements) from b into tmp at the location specified by IMM8, and copy tmp to dst using writemask k (elements are copied from src if the corresponding bit is not set).
