------- Comment #1 from pinskia at gcc dot gnu dot org 2007-09-26 08:59 ------- They are included as far as I can tell: @item -fstack-protector Emit extra code to check for buffer overflows, such as stack smashing attacks. This is done by adding a guard variable to functions with vulnerable objects. This includes functions that call alloca, and functions with buffers larger than 8 bytes. The guards are initialized when a function is entered and then checked when the function exits. If a guard check fails, an error message is printed and the program exits.
@item -fstack-protector-all Like @option{-fstack-protector} except that all functions are protected. They are documented http://gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/Optimize-Options.html#Optimize-Options Though I see they are not part of the option index. -- pinskia at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Component|c |middle-end http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33559
