Comments on: Parsing C++ with GCC plugins, Part 1 https://codesynthesis.com/~boris/blog//2010/05/03/parsing-cxx-with-gcc-plugin-part-1/ Boris Kolpackov's blog about software Wed, 08 Apr 2026 09:07:42 +0000 http://wordpress.org/?v=2.2.2 By: Chad Colgur https://codesynthesis.com/~boris/blog//2010/05/03/parsing-cxx-with-gcc-plugin-part-1/#comment-1512 Chad Colgur Sun, 30 May 2010 17:56:26 +0000 https://codesynthesis.com/~boris/blog//2010/05/03/parsing-cxx-with-gcc-plugin-part-1/#comment-1512 Thanks for the post. So right about the state of plug-in API documentation. Still, an incredibly useful addition to GCC. If you're taking requests for this series of blog posts then static analysis would be of interest to me. My interest is program slicing, particularly amorphous slices (http://doi.ieeecomputersociety.org/10.1109/WPC.1997.601266). Thanks for the post. So right about the state of plug-in API documentation.

I always hope to create a refactoring tool for C++. But the parsing work is really killing me T_T I am very interested in it! I always hope to create a refactoring tool for C++.

The GCC test suite contains a couple of basic examples of this: http://gcc.gnu.org/viewcvs/trunk/gcc/testsuite/gcc.dg/plugin/ The finish_unit_plugin.c shows how to create a function and start_unit_plugin.c shows how to create a global variable. But for more serious modifications the GCC Internals documentation and the GCC source code are probably your best bet. Boris Dmitriy,

I would like to read more about plugins. Btw, is it possible to modify AST with plugins? What I would like to do is to add some arguments to some function calls. And it is possible to get the functionality of __FILE__, __LINE__, __FUNCTION__? Currently I have: #define INFO debug_info_t(__FILE__, __LINE__, __FUNCTION__) void foo(..., debug_info_t info); foo(..., INFO); I would like to eliminate those INFO parameters. Hi,
