pub unsafe fn _mm_mask3_fnmadd_ss(
a: __m128,
b: __m128,
c: __m128,
k: __mmask8
) -> __m128This is supported on (non-crate feature

Multiply the lower single-precision (32-bit) floating-point elements in a and b, and add the negated intermediate result to the lower element in c. 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.
