For

(note 21 8 17 2 (expr_list:REG_DEP_TRUE (concat:SI (reg:SI 5 di) 
(subreg:SI (plus:DI (reg/f:DI 16 argp)
(const_int -20 [0xffec])) 0)) 
(nil)) NOTE_INSN_CALL_ARG_LOCATION)

when

(plus:DI (reg/f:DI 16 argp)
(const_int -20 [0xffec]))

reaches

   case PLUS: 
plus: 
  if (is_based_loc (rtl) 
   GET_MODE_SIZE (mode) = DWARF2_ADDR_SIZE
   GET_MODE_CLASS (mode) == MODE_INT)
mem_loc_result = based_loc_descr (XEXP (rtl, 0),
  INTVAL (XEXP (rtl, 1)),
  VAR_INIT_STATUS_INITIALIZED);
  else  

it fails GET_MODE_SIZE (mode) = DWARF2_ADDR_SIZE since
we have ptr_mode = SImode and Pmode == DImode.  However,
arg_pointer_rtx and frame_pointer_rtx are special cases.
They should be allowed even if their mode sizes 
DWARF2_ADDR_SIZE.
