Hi,
I've tried to use the treebrowser described at http://gcc.gnu.org/projects/tree-ssa/tree-browser.html
I configuired gcc-4.5.0 with ... --enable-checking --enable-tree-browse --enable-tree-checking ...
Compilation was OK, a gcc/tree-browser.o exists.
Now i'm able to launch gdb and step through the code, etc.
When I type the suggested command, I get
(gdb) p browse_tree (current_function_decl)
No symbol "browse_tree" in current context.
(gdb)
What i'm doing wrong? Any ideas?
Thanks,
Wolfgang

The tree browser code has bitrotted to the point that I think it should
be removed, unfortunately. It's a great candidate to be re-implemented
as a plugin.
I know this does not help you much. Sorry. In this case, it is likely
that since there are no calls to browse_tree anywhere in the code, the
linker is removing it. Are you building cc1 with -O0?
Diego.

It probably also can be re-implemented as gdb python script?

Hi,
Try using gcc-vcg-plugin to browse tree and cfg during debug gcc. It's
just an initial version for now. Any suggestions will be appreciated.
