[bug-cflow] Help, please! I want to analyse ALL functions in a set of C files.

[Alan Mackenzie]

Hello, cflow.

As an Emacs maintainer, I want to get a cflow tree analysis of all the C
functions in Emacs.  I've tried with

    $ cflow -b --cpp `cat ~/emacs-cflow-ls.txt` *.c

, where ~/emacs-cflow-ls.txt just contains a large number of -I include
directory directives, extracted from Emacs's makefile.  Unfortunately,
not all functions are included in the output.

My problem seems to be that only the functions directly called from
main() are getting processed.  This omits most Emacs "primitives", C
functions which get called by name from the Lisp interpreter rather than
from main().

I've scanned the cflow manual's options page, looking for some way to
enable "all functions", without finding one.  Is there some way I can get
what I need from cflow?

Thanks in advance!
