[cfe-dev] Parsing All Comments

[Chengnian Sun via cfe-dev]

Thank you for your reply. The comment is very simple. Each function
definition has a preceding comment, listing all the global variables used
in the function definition. I need to parse this comment to get the
variable list.

Yes, I actually found another old post mentioning
CommentOptions::ParseAllComments.
However I am new to LLVM/Clang, and I found out it was just a structure
defined in CommentOptions.h if I am not wrong.

The following shows the stub of my LitTooling code. Any advice will be
appreciated. Thank you.





class InstrumentAction : public ASTFrontendAction {
public:
  virtual std::unique_ptr<ASTConsumer> CreateASTConsumer(CompilerInstance
&CI,
                                                         StringRef InFile){
    errs() << "Processing " << InFile << "\n";
    return std::unique_ptr<ASTConsumer>(
      new Instrument(InFile, CI.getASTContext(), InstrumentProb));
  }
};

int main(int argc, const char **argv) {
  InstrumentProb.setCategory(MyToolCategory);
  CommonOptionsParser OptionsParser(argc, argv, MyToolCategory);
  ClangTool
Tool(OptionsParser.getCompilations(), OptionsParser.getSourcePathList());
  return Tool.run(newFrontendActionFactory<InstrumentAction>().get());
}
