A question about g++ dump files

[shira]

Hello,

I have a question about binary files of g++ , please:
in the option
g++ -fdump-class-hierarchy source.cpp
I get the hierarchies of c++ in memory, in a file named source.cpp.class
How can I get the binary data of it?

thanks,
Shira

I have never used the -fdump-class-hierarchy option before. I have just now done so, because of your question So I haven't the foggiest notion how to answer the question, but nobody else has taken a crack at it for five hours, so I'll give it a shot.

I pretty much understand what the compiler has done with this option, so my question to you is: What do you mean by

How can I get the binary data of it?

What do you want to accomplish?

Hi and thank you for trying to help.

I would like to get static data about class hierarchies and virtual methods for given c++ files. The format that you got (file *.cpp.class) is eddited.
It seems that this data exists in some file and from it the resulting file is given. Is there a file where this static data can be, not eddited, so I'll be able to parse the file more easily?

Ok, your question now seems fairly simple. I'm guessing that the answer is "no". I did a careless google for

fdump-class-hierarchy

and found nothing useful, but you may wish to do a more thorough search. If you do, don't search for this:

-fdump-class-hierarchy

because google uses a hyphen at the beginning of a word to mean "exclude anything containing this word from the search results".

You could possibly hack the code of the compiler itself, if you're so inclined. I vote for biting the bullet and parsing the output with a tool you write yourself.

Sorry I couldn't be of more help than this.
