--- Comment #2 from Eric Botcazou <ebotcazou at gcc dot gnu.org> ---
The error_mark_node very likely comes from:

DEF_PRIMITIVE_TYPE (BT_UINT128, uint128_type_node
                                ? uint128_type_node
                                : error_mark_node)

but this is a standard idiom in builtin-types.def so rather strange indeed.

I gather that targetm.scalar_mode_supported_p (TImode) returns false for GC=
N?=
