gcc front end

gcc front end

[Sean PH]

 Hello,
 
 I'm currently working on implementing a tool chain for a 'pet
language' of mine called O (for Obscure, since my preferred name was
taken). You can see the [unfinished] language specification here:
 
 http://sean.heybryan.org/spec0_unfinished.pdf
 
 Note that the implementation notes chapter isn't filled in since I
havn't gotten around to finding a back-end for the compiler yet. gcc
looks like a very good option, however the documentation is quite
'preliminary' and I am having trouble understanding some things. Would
anyone there be willing to help me on this, even just to talk about
gcc's features and how I would apply my language constructs to them at
first? I am approaching a point at which I have a full parse tree of
the language available and will be ready to dive into connecting it to
a back end, so this would be much appreciated.
 
 Sorry for any grammar errors, they're unintentional as I just pulled
an all-nighter :).
 
 Thanks, Sean Purser-Haskell

I think that you should take a look at the GCC front end HOWTO. Some parts of 
it are out of date but most of it is quite useful. Studing other front ends 
is also helpfull. I have made a very small Hello World front end to show what 
is the smallest program that can link with the gcc middle end. I is not 
completely documented, but I think that it can be usefull. It is at
http://svn.gna.org/viewcvs/gsc/branches/hello-world/

A much more mature example is the treelang front end that comes with gcc. I 
also think that the fortran front end is a very good reference.

Wen you have more specific question feel free to ask. :)

AFAIK there is no library version of g++.

Hi ,
I'm currently trying to make a tool that'll generate
UML specs from c++ code.

I am searching for a library version of GNU's C++
front end , and documentation on its interface
(through which I can query its internal data str.)

I'm using g++ 2.96 on linux 7.2.

Could you please guide me to the correct library and
where I could download it ?
I explored the links on the gcc pages but could not
locate these.

thanks & regards,
praveen.
