    mov dr(x),reg (serializing instruction)

    ouadji

      hi all,


      first ... sorry about my english, I'm Belgian.

      I will try to do my best.

       

      I have a question about the serializing instructions.


      Intel Manual 3A/8.3


      The example shows the use of a new value
      ... but there is nothing about this in the "text".

       

      mov to debug register ... mov dr(x),reg

      Is it absolutely necessary to use a "new value" to get a real serializing behavior ?  ... or not ?

       

      Has someone an experience about it ?
