WebYou can handle the AST manually, but clang also provides a visitor traversal helper class RecursiveASTVisitor. You simply create a new instance of the visitor, and let it visit the translation unit decl. The visitor itself implement what to do with each AST node. Override the list of VisitXXX method for each type of AST node. WebThe Clang Compiler is an open-source compiler for the C family of programming languages, aiming to be the best in class implementation of these languages. Clang builds on the LLVM optimizer and code generator, allowing it to provide high-quality optimization and code generation support for many targets. For more general information, please see …

WebAn AST dump is generated by a compiler command like: $ clang++ -Xclang -ast-dump=json -fsyntax-only path/to/source.cc. The high-level structure is a tree of nodes, each of which has an "id" and a "kind", zero or more further fields depending on what the node kind is, and finally an optional "inner" array of child nodes.
