GCC can dump its internal representation at almost every stage of the compilation process. However, it's intended for diagnosing issues in the compilers or plugins ; it's definitely not meant to be used as an interoperable format to be loaded back into a program. gcc doesn't even provide a way to specify the output path for the dump file (too bad, as reliable AST dumping could enable implementing ast-based-ccache (instead of preprocessed-code-based-ccache, for compilation-caching of preprocessor-less languages)).
