如何克隆或创建CAST的AST Stmt节点? [英] How to clone or create an AST Stmt node of clang?

问题描述

我想通过clang LibTooling修改AST.如何克隆AST节点或添加新节点，例如我想用ADD操作码创建一个BinaryOperator

I want to modify the AST by clang LibTooling. How can I clone an AST node or add a new one, e.g. I'd like to create a BinaryOperator with ADD opcode

推荐答案

在Clang中创建新的AST节点非常繁琐，因此不建议使用libTooling.相反，您应该读取" AST并发出代码或代码更改(重写，替换等).

Creating new AST nodes is quite cumbersome in Clang, and it's not the recommended way to use libTooling. Rather, you should "read" the AST and emit back code, or code changes (rewritings, replacements, etc).
