Good morning. I would like to use gcc for limited source code analysis. I am interested in description of declarations only. I found "dump-translation-unit" option very useful for this, but unfortunately it dumps only description of used declarations. I read the manuals and searched the Internet, but was not able to find flag or combination of flags that would cause gcc to dump all declarations. I am afraid such functionality is not implemented, am I right? If so can you suggest reasonable solution? P.S. Please tell me that I wrong :-) Thank you.
