Bug ID: 84695 Summary: Missed opportunity to issue warning about override Product: gcc Version: 8.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: drepper.fsp+rhbz at gmail dot com Target Milestone: --- Stroustrup in [1] ยง20.3.4 writes the compilers should issue warnings about inconsistent use of explicit override controls. struct foo { virtual int one(int) { return 1; } virtual int two(int) { return 2; } }; struct bar : foo { int one(int) override { return 101; } int two(int) { return 102; } }; bar b; In this case the compiler should issue a warning about bar::two. This is different from -Wsuggest-override. That command line option causes a warning to be issued but the fact that bar::one uses override should automatically turn on this type of warnings for the rest of the class. I would even say there is no need for a further command line option, it should just been done. [1] http://www.stroustrup.com/4th.html
