[cfe-dev] Macro expansion with Clang

[Alexander Basov]

Hello.
Could somebody help me with macro expansion?

I have a header with the following macroses defined:

#define foo(x) x + 2
#define A 1
#define B foo(A)

And I need get the following map:
A = 1
B = 3

How can I do it?

I'm ale to get list of MacroInfo * classes with PPCallbacks or get it with
Preprocessor::macro_begin() iterator, but I don't know how to get expaneded
value.

Thank you in advance.
