Function core::arch::x86::_mm256_insertf32x4

pub unsafe fn _mm256_insertf32x4(
    a: __m256, 
    b: __m128, 
    const IMM8: i32
) -> __m256

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

This is supported on x86 and target feature avx512f,avx512vl only.

Copy a to dst, then insert 128 bits (composed of 4 packed single-precision (32-bit) floating-point elements) from b into dst at the location specified by imm8.
