Yes, I mean when -fstack-usage is enabled. Thus, make -fstack-usage -Wframe-larger-than behave the same as -fstack-usage -Wstack-usage. Or do you say that -Wstack-usage doesn't require -fstack-usage? If it doesn't then I hope -Wstack-usage does not have effects on code generation? And if not then why can't -Wframe-larger-than just be more precise on some targets? Richard. > -- > Eric Botcazou >
