If you have a legal question, you should ask an attorney who specializes
in copyright law as it applies to computer software. Do not rely on
anything you get as a response to your question online.
The below is my opinion, based on my understanding of current copyright
law, but I am not an attorney:

If NAC is *your* representation, rather than that of some standard
(such as a published assembler representation of some real machine), then
they would both be considered derived works from each other. Since
the first is covered by the GPL, the second must also.
