8894 * c-common.c (c_common_nodes_and_builtins): Since variants of
8895 void_type_node get built before it is given a name, we need to
8896 give those variants the name, too.
8897 (complete_array_type): We need to work with the canonical main
8898 type of the array, from which we will build the qualified version.

8902 * stor-layout.c (layout_type): When we don't know the
8903 alignment of a type for which we're building an array, we end up
8904 guessing wrong, so make the type require structural equality.
8905 * tree.c (make_node_stat): When we build a new type, it is its
8907 (build_type_attribute_qual_variant): When building an attribute
8908 variant, its canonical type is the non-attribute variant. However,
8909 if the attributes are target-dependent and they differ, we need to
8910 use structural equality checks for this type.
8911 (build_qualified_type): A qualified type is not equivalent to its
8912 unqualified variant; set the canonical type appropriately.
8913 (build_distinct_type_copy): When building a distinct type from
8914 another type, the new type is its own canonical type.
8915 (build_variant_type_copy): When building a new type variant, we
8916 assume that it is equivalent to the original type.
8917 (build_pointer_type_for_mode): When building a pointer type, also
8918 build a canonical type pointer.
8919 (build_reference_type_for_mode): When building a reference type,
8920 also build a canonical type reference.
8921 (build_index_type): When we can't hash an index type (e.g.,
8922 because its maximum value is negative), the index type requires
8923 structural equality tests.
8924 (build_array_type): Build the canonical form of an array type.
8925 (build_function_type): Function types require structural equality,
8926 because they contain default arguments, attributes, etc.
8927 (build_method_type_directly): Ditto for method types.
8928 (build_offset_type): Build the canonical offset type.
8929 (build_complex_type): Build the canonical vector type.
