================
Comment at: clang/include/clang/Driver/Options.td:3445
 def mcode_object_version_EQ : Joined<["-"], "mcode-object-version=">, Group<m_Group>,
-  HelpText<"Specify code object ABI version. Defaults to 4. (AMDGPU only)">,
-  MetaVarName<"<version>">, Values<"2,3,4,5">;
+  HelpText<"Specify code object ABI version. Allowed values are 2, 3, 4, and 5. Defaults to 4. (AMDGPU only)">,
+  Flags<[CC1Option]>,
----------------
`none` is missing. I'm not sure if we need to enumerate all values -- the list will eventually grow unacceptably long. 
Does the option parser print allowed values on error? That would be sufficient, IMO. 
Up to you.


================
Comment at: clang/lib/Driver/ToolChains/Clang.cpp:1166
     CmdArgs.insert(CmdArgs.begin() + 1, "-mllvm");
+    // -cc1as does not need -mcode-object-version option.
+    if (!IsCC1As)
----------------
Do we really need a special case for `-cc1as`? What happens if we do pass the option to it? 

If cc1as does need a special case handling, we may want to add a test case for that.
