The dump files generated by gcc are intended only as debugging aids. 
They are not intended to be read by other programs.  You may or may not 
be able to use them for this purpose.

There is no documentation for the format of the dump files themselves. 
The format may change whenever it is convenient for us to do so.

There is documentation for the structure of the trees that we use.  See 
the gcc internals documentation, either in the source tree or on the web 
page.  The format of the dump files follows from that.

You may also want to take a look at the papers published in the GCC 
conference.  Some of them discuss the tree structures we use, 
particularly the tree-ssa papers.  There are pointers to these 
conference proceedings in the wiki off of our web page.
