Hi,I need precise information about how GCC store the objects for c++ and objective-C
For C++, the source of information is the C++ ABI. See http://www.codesourcery.com/cxx-abi/
For Objective-C, I don't know and I suspect the answer is that the information is only in the source code to libobjc, which however is pretty manageable.
