From: "bkoz at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/47693] New: warning flag for emission of vague linkage bits Date: Fri, 11 Feb 2011 01:26:00 -0000 [thread overview] Message-ID: <bug-47693-4@http.gcc.gnu.org/bugzilla/> (raw) http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47693 Summary: warning flag for emission of vague linkage bits Product: gcc Version: 4.6.0 Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: c++ AssignedTo: unassigned@gcc.gnu.org ReportedBy: bkoz@gcc.gnu.org Request for -Wvague-linkage. This flag would warn for the lack of key function, etc that makes typeinfo/vtable information emitted in every TU for polymorphic classes class regex_error : public std::runtime_error { public: explicit regex_error(regex_constants::error_type __ecode) : std::runtime_error("regex_error"), _M_code(__ecode) { } regex_constants::error_type code() const { return _M_code; } protected: regex_constants::error_type _M_code; }; It's hard to scan through the libstdc++ sources for other places where maintainers might want to know exact linkage. However, the compiler already knows this.
