12411
12412         * c-common.c (c_common_nodes_and_builtins): Since variants of
12413         void_type_node get built before it is given a name, we need to
12414         give those variants the name, too.
12415         (complete_array_type): We need to work with the canonical main
12416         type of the array, from which we will build the qualified version.

12421         alignment of a type for which we're building an array, we end up
12422         guessing wrong, so make the type require structural equality.
12423         * tree.c (make_node_stat): When we build a new type, it is its
12424         own canonical type.
12425         (build_type_attribute_qual_variant): When building an attribute
12426         variant, its canonical type is the non-attribute variant. However,
12427         if the attributes are target-dependent and they differ, we need to
12428         use structural equality checks for this type.
12429         (build_qualified_type): A qualified type is not equivalent to its
12430         unqualified variant; set the canonical type appropriately.
12431         (build_distinct_type_copy): When building a distinct type from
12432         another type, the new type is its own canonical type.

12434         assume that it is equivalent to the original type.

12438         also build a canonical type reference.
12439         (build_index_type): When we can't hash an index type (e.g.,
12440         because its maximum value is negative), the index type requires
12441         structural equality tests.
12442         (build_array_type): Build the canonical form of an array type.
12443         (build_function_type): Function types require structural equality,
12444         because they contain default arguments, attributes, etc.
12445         (build_method_type_directly): Ditto for method types.
12446         (build_offset_type): Build the canonical offset type.
