Function core::arch::x86::_mm256_mask_dpbf16_ps

pub unsafe fn _mm256_mask_dpbf16_ps(
    src: __m256, 
    k: __mmask8, 
    a: __m256bh, 
    b: __m256bh
) -> __m256

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

Available on x86 and target feature avx512bf16,avx512vl only.

Compute dot-product of BF16 (16-bit) floating-point pairs in a and b, accumulating the intermediate single-precision (32-bit) floating-point elements with elements in src, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
