Yes, -Wstack-usage doesn't require -fstack-usage. > If it doesn't then I hope -Wstack-usage does not have effects on code > generation? Neither -fstack-usage nor -Wstack-usage has any effect on code generation. The former generates a .su file and the latter issues a warning. > And if not then why can't -Wframe-larger-than just be more precise on some > targets? -Wframe-larger-than is documented to work on any targets and to be imprecise. So we would need to list the targets for which it is precise (or the targets for which it isn't precise) and maintain it. By contrast, if -Wstack-usage returns something, then the answer is always precise. Moreover I think that the common name is a big advantage. -- Eric Botcazou
