Function core::arch::x86::_mm512_mask_insertf32x4

pub unsafe fn _mm512_mask_insertf32x4(
    src: __m512,
    k: __mmask16,
    a: __m512,
    b: __m128,
    const IMM8: i32
) -> __m512

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

Available on (x86 or x86-64) and target feature avx512f and x86 only.

Copy a to tmp, then insert 128 bits (composed of 4 packed single-precision (32-bit) floating-point elements) from b into tmp at the location specified by imm8. Store tmp to dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
