Yes, I think that's one issue - see

That's true. But if you
Hello,
If I use the -fdump-tree-original-raw option
of gcc, I understand it will dump out the AST
in a text file.
Is that text file complete?
Complete in the sense that, by parsing back this text file
with an external program it would be possible to reconstruct the original AST
that gcc was work
If you made a presentation at this year's Cauldron and are
allowed to share your slides, please add them to the wiki
in the slides and notes section:

If you don't have access to GCC's wiki, you can create your own
user. If that does not work

It isn't. These dumps are meant to be debugging aids.
Hello,
I would like to encapsulate all symtab_nodes to a class called 'symtab'. To
respect gcc:context, I would like to add the class to global context
(gcc::context) and I have troubles with GTY and GGC.
design:
class GTY(()) symtab
{
public:
symtab_node* GTY(()) nodes;
};
class GTY(())

I take it they'll be available in an unencumbered format such as WebM, not
just MP4? (Some of the video links from the Cauldron 2013
