GCC-XML will parse any set of valid C++ sources because it uses a
compiler's parser.  All declarations and template instantiations are
dumped with their file name and line number.  A program such as what you
have in mind could use this information to look at each line.

However, GCC-XML currently does not support function bodies, so finding
all the references to a method or function would require extra parsing
after reading GCC-XML's output.  It also does not dump uninstantiated
class or function templates, so these would be missed unless explicit care
were taken to create instantiations.
