There is a nice tool called egypt (http://www.gson.org/egypt/), which operates on the output of 'gfortran -fdump-rtl-expand'. This seems like a good choice for your purpose, since it's open source and works with Fortran and C. Cheers, Janus

It generates html code and ascii files, see an example here http://www.ii.uib.no/~avle/work/bom/bom.html Not sure if you can call it "good", but it works on many codes. The tool was initially created in order to build the monster code "arpege climat" in parallel, but also works for other codes. The tool can be downloaded from http://www.ii.uib.no/~avle/mkdep2.tgz To install, unpack, enter directory "mkdep" and do "python install.py", then add directory to path. Simple usage; lets say you have a bunch of .f90 files in a directory tree find . -name "*.f90" > files mkdep -t tree files firefox tree.html should create a html page like the example above. if you only need the tree above the routine TEST3 you can instead say mkdep -t tree --treetop TEST3 files The fortran parser is simple, it can detect subroutine and function calls, but do not know much about name spaces or if a routine is contained etc. if the code is peppered with cpp directives intermingled with strings that are continued over multiple lines it can easily be confused... -- Helge |
