[Haifux] A question about g++ dump files

[shirab at t2.technion.ac.il]

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
