Function core::arch::x86_64::_mm512_mask_mullox_epi64[][src]

pub unsafe fn _mm512_mask_mullox_epi64(
    src: __m512i,
    k: __mmask8,
    a: __m512i,
    b: __m512i
) -> __m512i
🔬 This is a nightly-only experimental API. (stdsimd #48556)
This is supported on x86-64 and target feature avx512f only.
Expand description

Multiplies elements in packed 64-bit integer vectors a and b together, storing the lower 64 bits of the result in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
