12788 * c-common.c (c_common_nodes_and_builtins): Since variants of
12789 void_type_node get built before it is given a name, we need to
12790 give those variants the name, too.
12791 (complete_array_type): We need to work with the canonical main

12796 * stor-layout.c (layout_type): When we don't know the
12797 alignment of a type for which we're building an array, we end up
12798 guessing wrong, so make the type require structural equality.
12799 * tree.c (make_node_stat): When we build a new type, it is its
12800 own canonical type.
12801 (build_type_attribute_qual_variant): When building an attribute
12802 variant, its canonical type is the non-attribute variant. However,
12803 if the attributes are target-dependent and they differ, we need to
12804 use structural equality checks for this type.
12805 (build_qualified_type): A qualified type is not equivalent to its
12806 unqualified variant; set the canonical type appropriately.
12807 (build_distinct_type_copy): When building a distinct type from
12808 another type, the new type is its own canonical type.
12809 (build_variant_type_copy): When building a new type variant, we
12810 assume that it is equivalent to the original type.
12811 (build_pointer_type_for_mode): When building a pointer type, also
12812 build a canonical type pointer.
12813 (build_reference_type_for_mode): When building a reference type,
12814 also build a canonical type reference.
12815 (build_index_type): When we can't hash an index type (e.g.,
12816 because its maximum value is negative), the index type requires
12817 structural equality tests.
12818 (build_array_type): Build the canonical form of an array type.
12819 (build_function_type): Function types require structural equality,
12820 because they contain default arguments, attributes, etc.
12821 (build_method_type_directly): Ditto for method types.
