+void Clang::AddXCoreTargetArgs(const ArgList &Args,
+                                 ArgStringList &CmdArgs) const {
+  CmdArgs.push_back("-fno-common");

This isn't right; if you want to default to -fno-common, you should
modify the existing OPT_fcommon handling.

+  // int getDwarfEHStackPointer(CodeGen::CodeGenModule &CGM) const {return 14;}

Why is this commented out?

You're missing tests for the driver changes.

Otherwise, looks fine.
