--- Comment #2 from Tom de Vries <vries at gcc dot gnu.org> ---
I've looked at the odr-struct.sh fail.

First of all, odr is not enabled because the language is DW_LANG_C_plus_plu=
s_14
instead of DW_LANG_C_plus_plus, so we need this in a few places:
...
     case DW_LANG_C_plus_plus:
+    case DW_LANG_C_plus_plus_03:
+    case DW_LANG_C_plus_plus_11:
+    case DW_LANG_C_plus_plus_14:
...

Then, it seems the checksums for both struct aaa are different, because of
processing a DW_AT_decl_line with DW_FORM_implicit_const.  The const has the
same value (according to readelf), but somehow the resulting hashes are
different.
