Shadow Call Stack can be used to protect the return address of a function at runtime, and clang already supports this feature[1]. To enable SCS in user mode, in addition to compiler, other support is also required (as discussed in [2]). This patch only adds basic support for SCS from the compiler side, and provides convenience for users to enable SCS. For linux kernel, only the support of the compiler is required.
