Function core::arch::x86::_mm256_mask_expand_ps

pub unsafe fn _mm256_mask_expand_ps(
    src: __m256, 
    k: __mmask8, 
    a: __m256
) -> __m256

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

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

Load contiguous active single-precision (32-bit) floating-point elements from a (those with their respective bit set in mask k), and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
