Just for fun i'm attaching output for fortran, c, cp as per the "Examples" comment in the header of the script. sample line for cp: gcc/cp/cvt.o: Symbol 'cp_get_callee_fndecl(tree_node*)' declared extern but never referenced externally sample for c: gcc/c/c-decl.o: Symbol 'pending_invalid_xref_location' declared extern but never referenced externally gcc/c/c-decl.o: Symbol 'pending_invalid_xref' declared extern but never referenced externally I may find time to take care of the fortran spots later on, fwiw. As per the comment inline, one could add support for extracting archive-members. This would allow to optionally put the script near the actual linking of e.g the compilers to see unwarranted extern symbols quickly. But OTOH maybe that's a bit too much. :) HTH PS: I have to admit that flagging unused fields is a nice thing. Does somebody know of an existing gcc plugin that does that?
