I saw by this patch many UNSPEC notes in dwarf. As said before we
have here a field of unspecs (in as CONST { list-of-symbols }) for
which delegitimize_address isn't called.
The culprit code is in 'const_ok_for_output' the following block:
if (GET_CODE (rtl) == CONST)
return for_each_rtx (&XEXP (rtl, 0), const_ok_for_output_1, NULL) == 0;
