Hi,
is there a simple way to get the whole callgraph of the GCC 4.0.0?
I tried to get it with gprof, but I think I make something wrong,
because I only got a very little callgraph with only a few functions.
Is there an install- or configure-option or something like that for my
request?
Thanks a lot
Nico

I'll bet this is because you generated the callgraph of the tiny gcc
executable, and not the callgraph of the real compiler (cc1 or cc1plus).

You are not giving many details. What commands did you try exactly?
Did you check that all the .o files in cc1/cc1plus were compiled with -
pg? How are you running cc1?
Diego.

Hi,
I tried it with the cc1, but I can't find any function from the "middle
end" (tree-ssa ...) in the call graph. there are only functions like
these:
[47] _build_compound_lit [35] _get_parm_info [30] _pop_scope
[41] _builtin_function [44] _global_bindings_p [53] _push_scope
[34] _c_lex_with_flags [48] _grokdeclarator [51]
_shadow_tag_warned
[33] _c_parse_init [49] _grokfield [46] _start_decl
[38] _declare_label [50] _implicitly_declare [54]
_undeclared_variabl
[43] _define_label [45] _lex_string [37] _yyerror
[52] _duplicate_decls [39] _make_label [36] _yylex
[42] _finish_decl [31] _merge_decls [32] _yyparse
[29] _finish_struct [40] _parser_xref_tag
:-(
I'm missing a lot of functions ...

sorry.

make -n gives me something like this:
--------------------------
gcc -c -g -pg -O2 -DIN_GCC -W -Wall -Wwrite-strings
-Wstrict-prototypes -Wmissing-prototypes -fno-common -DHAVE_CONFIG_H
-I. -I. -I../../gcc -I../../gcc/. -I../../gcc/../include -I./../intl
-I../../gcc/../libcpp/include ../../gcc/tree-ssa.c -o tree-ssa.o
--------------------------
i think its ok.
> How are you running cc1?
usr/local/gcc-4.0.0-test/bin/gcc ./main.c
oops ... and there was the mistake! sorry.
Thank you
ciao
