Function core::arch::x86_64::_mm_maskz_fnmsub_sd

pub unsafe fn _mm_maskz_fnmsub_sd(

    a: __m128d,
    b: __m128d,
    c: __m128d,

🔬This is a nightly-only experimental API. (stdarch_x86_avx512 #111137)

Available on (x86 or x86-64) and target feature avx512f and x86-64 only.

Multiply the lower double-precision (64-bit) floating-point elements in a and b, and subtract the lower element in c from the negated intermediate result. Store the result in dst using zeromask k (the element is zeroed out when mask bit 0 is not set), and copy the upper element from a to the upper element of dst.
