Hello.
I'am developing an statement detector for c++ and I would like to
detect if an statement is expanded from macro.
Can I detect in ast tree if an statement is expanded code from macro?
Thanks.
Hi Alberto,
As far as I understand it you want to know if a statement was expanded
from a preprocessor macro, right?
This isn't possible. The preprocessor is a separate thing altogether and
I doubt any preprocessing information remains for the compiler proper to
deal with.

This information is incorrect.
GCC tracks macro expansion information since GCC 4.7, and it has been
further improved and enabled by default in GCC 4.8. See the option
ftrack-macro-expansion and the interface located in
libcpp/include/line-map.h.
If you have trouble understanding the interface, f
Thanks for correcting me Manuel.
I am just getting acquainted with GCC4.7, good to know that information
has been added.
Cheers,
Paulo Matos
