Bug ID: 87956 Summary: Gcc should emit deprecation warnings when using throw() in C++ >= 17 Product: gcc Version: 9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: romain.geissler at amadeus dot com Target Milestone: --- Hi, Today gcc always generates an error when you use a dynamic exception specification with some exception. However I would expect we might also get a warning with -Wdeprecated for "throw()" expressions. With -std=gnu++17 -Wdeprecated #include <stdexcept> void f() throw(); // No deprecation warning saying you should use noexcept instead void g() throw(std::exception); // Errors in C++17 I would expect a deprecation warning for f. FYI, clang's -Wdeprecated flag finds and notifies about this. Cheers, Romain
