[cfe-dev] How to correlate macro expansions with AST nodes?

[Richard via cfe-dev]

Hi Team,

If I'm writing a clang-tidy check that focuses on replacing macros
with a more suitable modern construct, it's easy to analyze the macro
definitions by using the PP callbacks.  From the callbacks I can also
monitor the macro expansions, but the callback only gives me a
SourceRange for the expansion.

Is there a way I can correlate the SourceRange to the appropriate
nodes in the AST for further analysis?

Thanks,
-- Richard
