It seems to me that the answer had been already given in the message you
fully quoted: we cannot help you.
I don't wish to labour the point, but what I am trying to understand
is whether it is impossible or just impractical. Could you explain why
it is that it can't be done? For example, the file given out doesn't
maintain enough information about the graph, in which case, why is in
not possible to output enough information in such a format that it can
be read and parsed into a C structure?
Sorry if this is tedious, or I have missed something obvious.
Compilers are a new subject for me, but a C representation of a
control flow graph would be greatly benificial for some optimisations
I am trying to make to allow the use of light formal methods in GDB.
See here for a discussion:

And, by the way, I suggest not to top post: see
http://en.wikipedia.org/wiki/TOFU for more info.
Appologies.
Thanks for your help.
