It's not as easy to represent the data in the way you describe as you
might think. Something like gcc is going to have multiple entry points
in a graph, which is really hard to represent in a (sort of)
1-dimensional structure like a tree.

I haven't seen any tools that do this well, although I would be happy to
be wrong about it.

I would imagine that all of the ones you compiled with it do since they
are almost certainly linked with the libgcc that comes with gcc44.
