[−][src]

    pub unsafe fn _mm_mask3_fmsub_sd(
        a: __m128d,

        c: __m128d,

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512f` only.
Expand description

Multiply the lower double-precision (64-bit) floating-point elements in a and b, and subtract the lower element in c from the 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 element from c to the upper element of dst.
