For late generated vector types this might result in inconsistencies with early (user) generated types when using LTO. Is there context available somehow so we can do like the is_<LANG> overloads on a decl and use a default according to that? > > gcc/ > * dwarf2out.cc (gen_array_type_die): Use the default lower bound of > the language for vector types. > > -- > Eric Botcazou
