Objects in c++ and objc

[Come Lonfils]

Hi,

I need precise information about how GCC store the objects for c++ and 
objective-C. I'm trying to know what are the difference between both. I need a 
very precise description of both. Do you know where I can found this 
information (except in gccint), books or other? Maybe it's not the best place 
to ask but I find this information nowhere.

Thanks very much

messages in objective-C

[Come Lonfils]

Hi,
I'm trying to know more about how messages are send to the objects in 
objective-C, how they are store,... 
In which structures en how?
Where should I look in the source code of gcc to know it? I looked in libobjc 
but I'm a bit lost.

Thanks very much

messages in objective-C

[Come Lonfils]

Hello,

I've already asked some questions about the messages in objective-c. But I 
still not understand all.

When a program is running, and I send a message to an object, how is it done in 
gcc to sent this message to the good object and to execute the good method. 
Which structures are used to do it?

I see the objc_msg_lookup in sendmsg.c but where is it call?
I also see two hash lists (nst_method_hash_list and cls_method_hash_list) I 
think they are use to store messages at runtime but I don't understand how they 
are used.

Sorry my question is quite general but I don't know very much gcc. Can't juste 
someone help me to understand a bit more and to put me on the right way.

Thanks very much

thesis on mix c++ and objective-c

[Come Lonfils]

Hi,

I'm beginning a end study thesis  on "mix" c++ end objective-c in gcc.
I know there is already objective-c++ but I need all information I can have on 
the subject. What is already done and what is not (and why)?

I also need documentation for people who want to "enter" in gcc and to know how 
gcc work and how to modify it. I want to know how objective-c is compiled 
(translated in c and then compiled?).

For now I'm trying to have the most information I can have to know where I can 
go in this thesis .

Thank you

Côme Lonfils

Ok but is it documentation about objective-C++ to know how it work (I mean how 
objc++ is implemented in gcc). And more generally, is it documentation about 
GCC. Not documentation to know how use gcc but for people who want to know more 
about working of gcc.

Documentation about gcc

Hi,

Do you know where I can have documentation for developer who begin with gcc.
I want to know how work exactly gcc inside.
Do you know some books or web documents which can help me?

I need general documentation and more specially on how gcc compile objective-c 
and objective-c++.
And Also about the way to modify gcc.
