Function core::arch::x86_64::_mm256_mask_insertf32x4

pub unsafe fn _mm256_mask_insertf32x4<const IMM8: i32>(
    src: __m256, 
    k: __mmask8, 
    a: __m256, 
    b: __m128
) -> __m256

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

This is supported on x86-64 and target feature avx512f,avx512vl 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).
