can't use the ssa tree browser.

can't use the ssa tree browser.

[Matthieu Moy]

hi,

I've  cvs-ed  the   tree-ssa-20020619-branch  of  gcc,  configured  it
(../configure --prefix=$HOME/gcc-ssa/gcc/target \
               --enable-languages=c,c++)

Compilation was  OK. I removed the -02  flag, and keept the  -g in the
makefile. 

I can launch gdb cc1plus, put breakpoints, step through the code, ... 

Now,   I   want   to   use   the   tree-browser   described   here   :
http://gcc.gnu.org/projects/tree-ssa/tree-browser.html. 

When I type the suggested command, I get
(gdb) p browse_tree (current_function_decl)
No symbol "browse_tree" in current context.
(gdb)

the file  tree-browser.o exists.  Do I have  to load it  explicitely ?
(I've tried
(gdb) load tree-browser.o
You can't do that when your target is `child'
(gdb)
)

Any idea about what I'm doint wrong ? 

Thanks,

Since no function in tree-browser.o is ever called from GCC itself,
tree-browser.o is never linked in.  Try this patch.  It moves
tree-browser.o out of libbackend.a.

We probably need a better long term solution.  I don't want to have
tree-browser.o compiled-in by default.  We should probably add a configure
switch.  Suggestions welcome.
