28637
28638         * c-common.c (c_common_nodes_and_builtins): Since variants of
28639         void_type_node get built before it is given a name, we need to
28640         give those variants the name, too.
28641         (complete_array_type): We need to work with the canonical main
28642         type of the array, from which we will build the qualified version.

28647         alignment of a type for which we're building an array, we end up
28648         guessing wrong, so make the type require structural equality.
28649         * tree.c (make_node_stat): When we build a new type, it is its
28650         own canonical type.
28651         (build_type_attribute_qual_variant): When building an attribute
28652         variant, its canonical type is the non-attribute variant. However,
28653         if the attributes are target-dependent and they differ, we need to
28654         use structural equality checks for this type.
28655         (build_qualified_type): A qualified type is not equivalent to its
28656         unqualified variant; set the canonical type appropriately.
28657         (build_distinct_type_copy): When building a distinct type from
28658         another type, the new type is its own canonical type.

28660         assume that it is equivalent to the original type.

28664         also build a canonical type reference.
28665         (build_index_type): When we can't hash an index type (e.g.,
28666         because its maximum value is negative), the index type requires
28667         structural equality tests.
28668         (build_array_type): Build the canonical form of an array type.
28669         (build_function_type): Function types require structural equality,
28670         because they contain default arguments, attributes, etc.
28671         (build_method_type_directly): Ditto for method types.
28672         (build_offset_type): Build the canonical offset type.
