修改GCC编译器的AST树 [英] Modification of the AST-tree of the GCC compiler

问题描述

需要使用GCC插件收集有关翻译单元的必要信息，并在其基础上修改AST. 我已经了解了如何收集信息.但是我还不了解如何在将AST传递到CRT之前对其进行修改.关于此主题的信息很少. 告诉我请问我应该读什么?分享想法和链接.

It is needed to gather the necessary information about the translation unit using the plugin for GCC and to modify AST on its base. I've already understood how to gather information. But I haven't understand yet how to modify AST before it's passed into CRT. Very little information is available on this subject. Tell me plese what should I read on this subject? Share thoughts, links.

谢谢.

P.S. 我已经阅读了这些链接上的所有内容:

推荐答案

GCC测试套件包含此类修改的基本示例.参见 http://gcc.gnu. org/viewcvs/gcc/trunk/gcc/testsuite/gcc.dg/plugin/finish_unit_plugin.c 和start_unit_plugin.c显示了如何创建变量.不幸的是，对于更认真的修改，GCC源代码可能是最好的选择.

The GCC test suite contains a basic examples of such modifications. See http://gcc.gnu.org/viewcvs/gcc/trunk/gcc/testsuite/gcc.dg/plugin/finish_unit_plugin.c and start_unit_plugin.c shows how to create a var. Unfortunately for more serious modifications the GCC source code are probably your best bet.
