function prototypes
by Philip Herron 06 Jul '12

Hey I am using the latest GCC head and i have noticed some quite different behaviours when using the plugin than using gcc 4.6 which i think was what i was using before. Say i take the example script from http://gcc-python-plugin.readthedocs.org/en/latest/tree.html which prints out all the function decl information this exact example will not get any data what so ever. As it seems functions are not part of the translation unit from what i can tell. To work around this i have been getting functions from warn_unused_result which works. But then i have the problem which i am not sure if it did in the older gcc but gcc seems to not care about function prototypes at all. So if i have: t.h: extern int foobar (void); t.c include t.h int main () { return foobar (); } The only function i can seem to get access to is int main. I wonder am i missing something, but i cant seem to find a way to get access to these a prototypes. I am 99% gcc is producing code for these cause it makes sense, there is enough information to generate a function decl such that a call_expr can call it. --Phil
