#48556)Available on (x86 or x86-64) and target feature
avx512f
and x86-64 only.Expand description
Multiply packed double-precision (64-bit) floating-point elements in a and b, alternatively add and subtract packed elements in c to/from the intermediate result, and store the results in dst using writemask k (elements are copied from a when the corresponding mask bit is not set).
