Are you talking about Clang's AST (in which case you should ask your
question on cfe-dev, not here) or IR?
In either case, empty preprocessor defines are gone. There's no way to
recover them. Instead, define OPT and MAN to be something like
__attribute__((annotate("opt"))), which will be preserved.
