If -fstack-protector-all is enabled, gcc linker will need GCC SSP(Stack Smashing Protector) support, Since the implement of SSP is related to the OS, most of embedded toolchain does not provide ssp support, so an error will be reported when linking: enable CONFIG_LTO_FULL && CONFIG_STACK_CANARIES arm-none-eabi/bin/ld: cannot find -lssp_nonshared: No such file or directory arm-none-eabi/bin/ld: cannot find -lssp: No such file or directory https://github.com/gcc-mirror/gcc/blob/master/gcc/gcc.cc#L983-L985 Since nuttx has already implemented SSP related hook functions, so in this PR, we filter out this option in the link phase to ensure that the implementation of lssp/lssp_nonshared will not be referenced Signed-off-by: chao an <anchao@xiaomi.com>
