  26 /// \brief Multiplies two 64-bit integer values, which are selected from source

  28 ///    carry-less multiplication, and the 128-bit integer product is stored in
  29 ///    the destination.

  44 ///    An immediate value specifying which 64-bit values to select from the
  45 ///    operands.
  46 ///    Bit 0 is used to select a value from operand __X,
