#111137)Available on (x86 or x86-64) and target feature
avx512f,avx512vl
and x86-64 only.Expand description
Multiply packed double-precision (64-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 (elements are copied from a when the corresponding mask bit is not set).
