I have been banging my head against clang for a bit now trying to get a sense of how a few things work. Hence I have a complete beginner type question.
I am simply trying to construct an AST which I can use to do some source transformations.
In trying to work through some of the examples and older tutorials I have noticed that many use a preprocessor instance. With the recent version of clang there seems to be a fundamental difference in the way a preprocessor object is constructed. My first question is can anyone tell me how to reconcile the old methodology with the new. (ie does anyone have a decent example of this.)
The other approach to constructing an AST, it appears, is through the construction of a CompilerInstance. However I have only seen this used in plugin operations or in examples that are not constructing an AST. Are there any good examples of this behavior (operation) in a stand alone application?
Please feel free to correct my misguided notions of what is going on and I apologize for the complete beginner questions.
