[PATCH ARC 3/8] GAS: new ARC port

Are you sure ?

But OK, I am willing to accept this assertion.  Given that the machine 
number is different then, I no longer have any concerns about the e_flag 
bits.  But I do think that you ought to extend the warning message for 
when you detect old/unknown binaries in arc_elf_object_p().  Currently I 
think that you have:

   else
     {
       /* This is an old ARC, throw a warning. Probably the best is to
        * return FALSE.  */
       (*_bfd_error_handler)
	  (_("Warning: unset or old architecture flags. \n"
	     "	       Use default machine.\n"));
     }

Please could you extend this to something like:

   else
     {
       if (e_machine == EM_ARC)
         {
           (*_bfd_error_handler)
             (_("Error: The ARC4 architecture is no longer supported.\n");
            return FALSE;
         }
       else
         (*_bfd_error_handler)
	  (_("Warning: unset or old architecture flags.\n"
	     "	       Selecting the default ARC architecture.\n"));
     }

Cheers
