avx512fp16
and x86-64 only.Expand description
Multiply packed half-precision (16-bit) floating-point elements in a and b, subtract packed elements in c from the negated intermediate result, and store the results in dst using writemask k (the element is copied from c when the corresponding mask bit is not set).
