10.3速度也许会更慢,这个trend还在继续。因为:
-fstack-protector
Emit extra code to check for buffer overflows, such as stack smash‐
ing 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.
想想如果如他所说,The whole distro build with -fstack-protector,嘿嘿。
