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?

I am not sure what you mean by all possible code paths to a function,
but if you mean something like this,

What is that supposed to be? Is that a call stack?

Maybe I have misunderstood the OP's question.

Its the result of the command `semantic-symref-symbol'. It looks up your symbol in all your project include paths and presents all references to the symbol as links. You can jump to it with `RET' or you can view with `<space>'. In this case the symbol was a handy method I had written.

There is a similar function for tags with a small difference, instead of presenting it in a buffer, it cycles through all the matches in a "completion like" buffer. All of this is of course with the CVS version of CEDET.

Is that what the OP was looking for?


Open source is the future. It sets us free.
