Re: The AST tree modification. Edited.

Hi, as an addition to Balaji's answer. Please find attached an extract of a sample front-end generating various types of tree nodes (e.g. arrays, structs, ...). This used to work with an older version of GCC, but I'm not sure if this still works with the most recent version. Anyway, it should

Re: Interested In Doing Documentation Project

Hi Selma, I am interested in doing the front end documentation project. How do I sign up for that, or learn what is going on with it at this current time please? Perfect and thanks for your interest in doing documentation for GCC. Andi Hellmund and i have actually done alot of work into

Re: gcov/-ftest-coverage instrumentation for uninstantiated C++ function templates

Hey Manuel, I would like to be able to change this behaviour so non-instantiated code templates are considered as blocks (I think this is the term used by GCC/GCov). This would help me greatly to uncover unused/untested codes in a header/template-only library. First of all: Is this feasible

Re: gcc terms of use

Hey, When I build my software products via gcc can I use it with third party's proprietary software (not open source)? Yes. When I build my software products via gcc I must provide source code of my products in any case? No. You don't need to publish _your_ source code in this case. There are

"White paper" about GCC front-end internals

Hey ALL, after some time of source code investigations, testing and experiments, I finally bundled my experiences with GCC front-ends in a "white paper" about the internals of GCC front-ends. It is not really structured like a tutorial, but it should hopefully be usuable by GCC newbies to spee

Re: HelloGcc 2011 Workshop calling for topic speakers

Hey Hui, I put the GCC development mailing list on CC ... Andi HelloGcc Working Group was set up in 2007 by Chinese free software fans and developers in Beijing. With the goal of constructing a free, open, sharing technical community, we not only discuss and learn about GNU system tools(such a

Nice. Thanks for doing this. If it's not already there, could you add a link to this in http://gcc.gnu.org/wiki/GettingStarted ? Sure, Phil (Herron) and I could post it there. Ideally, we should also have a more-or-less thorough documentation in the gcc internals document about howto im

Re: PL/1 frontend

Hey Tom, You need to define a lang_tree_node type, even if its empty. See the lto frontend example. You could also look at this site (http://code.redbrain.co.uk/cgit.cgi/gcc-dev/tree/gcc/gcalc?h=documentation). It contains the front-end code for a very simple front-end showing the general/ex

[LTO] Open items in the ToDo list

Hey, I was recently reading through the wiki pages of the LTO branch and found several open items in the ToDo list which are generally interesting. I mainly kept an eye on item 7 (Browsing/dumping tools for LTO files), which seems for me to be a good task to deepen the knowledge about GCC in
