           << A->getAsString(Args) << TripleStr;
-    if (Value != "tls" && Value != "global") {
+    if (Value != "tls" && Value != "global" && Value != "sysreg") {
       D.Diag(diag::err_drv_invalid_value_with_suggestion)
----------------
TODO: tls is not supported on aarch64 in GCC.


================
Comment at: clang/lib/Driver/ToolChains/Clang.cpp:3114
 
   if (Arg *A = Args.getLastArg(options::OPT_mstack_protector_guard_offset_EQ)) {
     StringRef Value = A->getValue();
----------------
TODO: GCC treats this as mutually exclusive when OPT_mstack_protector_guard_EQ == global.
