Call graph emacs tool

[George Kadianakis]

Greetings,

I think I'm loosing faith in Emacs. It's the first time I'm looking
for a tool and I don't get countless .el scripts with a trivial Google
search.

I'm looking for a tool (preferably an Emacs tool, but _seriously_
anything will do) that will give me all possible code paths to a given
function of a C project.

For example:
Input: (magic-script function)
Output: 1) main() [main.c] -> function_1() [main.c] -> function_2() [oh.c] -> 
function_3() [oh.c] -> function_4() [ohlol.c] -> function() [yay.c]
        2) main() [main.c] -> function_5() [yay.c] -> function_3() [oh.c] -> 
function_2() [oh.c] -> function() [yay.c]
        3) etcetera

GNU cflow is actually doing that _but_ it doesn't support multiple
source files and it's not Emacs integrable.

Do you people know of any such tools?

Thank you :)
