[cfe-dev] Merging AST from Multiple Translation Units

[Uri Mann]

Hello everyone;

I'm trying to create a tool which transforms source using a class derived from ASTFrontendAction. The tool need to transform one or more source files and then produce a final source file which can reference symbols from all of the processed source files. I tried to use ASTMergeAction class by saving the ASTUnit at the inside my class's EndSourceFileAction(). But when the files are merged, ASTImporter emits multiple errors "cannot import unsupported AST node xxx". Is this the right way to do it?

Thanks in advance.
