Function core::arch::x86::_mm_mask3_fnmsub_ss

pub unsafe fn _mm_mask3_fnmsub_ss(
    a: __m128,
    b: __m128,
    c: __m128,
    k: __mmask8,
) -> __m128

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

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

Multiply the lower single-precision (32-bit) floating-point elements in a and b, and subtract the lower element in c from the negated intermediate result. Store the result in the lower element of dst using writemask k (the element is copied from c when mask bit 0 is not set), and copy the upper 3 packed elements from c to the upper elements of dst.
