pub fn _mm_mask3_fmsub_sh(a: __m128h, b: __m128h, c: __m128h, k: u8) -> __m128h🔬This is a nightly-only experimental API. (
stdarch_x86_avx512_f16)Expand description
Multiply the lower half-precision (16-bit) floating-point elements in a and b, and subtract packed elements 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 the mask bit 0 is not set), and copy the upper 7 packed elements from c to the upper elements of dst.
