The final binary size will be smaller and execute faster. But the debugging experience may be worst somehow. config COMPILE_OPTIMIZE_SIZE bool "Enable code size optimization options" if COMPILE_OPTIMIZE default y help Answer Y to add optimization options for small code size. The final binary size will be smaller. But the compile time may be a bit longer. config COMPILE_LTO bool "Enable link time optimization (LTO)" if COMPILE_OPTIMIZE_SIZE default y help Answer Y to add lto options for more smaller code size.

It also means you do not want to use debug modules, like shell,telnet,tftp,nfs and memory check, etc. If you select this option that means you enable a debug version for LiteOS. That means you want an opposite behaviour compared to release version. config DEBUG_KERNEL bool "Enable Debug LiteOS Kernel Resource" default n depends on DEBUG_VERSION help If you select this option that means you enable debugging kernel resource.

This feature puts, at the beginning of functions, a canary value on the stack just before the return address, and validates the value just before actually returning. Stack based buffer overflows (that need to overwrite this return address) now also overwrite the canary, which gets detected and the attack is then neutralized via a kernel panic. This feature requires gcc version 4.2 or above, or a distribution gcc with the feature backported. Older versions are automatically detected and for those versions, this configuration option is ignored. (and a warning is printed during bootup) config CC_NO_STACKPROTECTOR bool "-fno-stack-protector" config CC_STACKPROTECTOR bool "-fstack-protector" config CC_STACKPROTECTOR_STRONG bool "-fstack-protector-strong" config CC_STACKPROTECTOR_ALL bool "-fstack-protector-all" endchoice endmenu
