https://issues.dlang.org/show_bug.cgi?id=16447 Issue ID: 16447 Summary: Warn about auto return type when no return statement is present Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: enhancement Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: b2.temp gmx.com When an auto function contains no return statement a warning could be emitted. example: auto foo(int x) { asm { naked; add RAX, 1; ret; } } The return type here is "void". Other case can exist, even w/o iasm, where the coder can get strange and inaccurate error message if he's forget his return statement(s). - When an auto function, depending on the static if conditions, returns void or something then no warning, b/c to return the something a return statement is present. - When an auto function returns void and contains no return statement, warn. --
