mov dr(x),reg (serializing instruction)

1,214 Views

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 ?
