20999 * c-common.c (c_common_nodes_and_builtins): Since variants of
21000 void_type_node get built before it is given a name, we need to
21001 give those variants the name, too.
21002 (complete_array_type): We need to work with the canonical main

21007 * stor-layout.c (layout_type): When we don't know the
21008 alignment of a type for which we're building an array, we end up
21009 guessing wrong, so make the type require structural equality.
21010 * tree.c (make_node_stat): When we build a new type, it is its
21011 own canonical type.
21012 (build_type_attribute_qual_variant): When building an attribute
21013 variant, its canonical type is the non-attribute variant. However,
21014 if the attributes are target-dependent and they differ, we need to
21015 use structural equality checks for this type.
21016 (build_qualified_type): A qualified type is not equivalent to its
21017 unqualified variant; set the canonical type appropriately.
21018 (build_distinct_type_copy): When building a distinct type from
21019 another type, the new type is its own canonical type.
21020 (build_variant_type_copy): When building a new type variant, we
21021 assume that it is equivalent to the original type.
21022 (build_pointer_type_for_mode): When building a pointer type, also
21023 build a canonical type pointer.
21024 (build_reference_type_for_mode): When building a reference type,
21025 also build a canonical type reference.
21026 (build_index_type): When we can't hash an index type (e.g.,
21027 because its maximum value is negative), the index type requires
21028 structural equality tests.
21029 (build_array_type): Build the canonical form of an array type.
21030 (build_function_type): Function types require structural equality,
21031 because they contain default arguments, attributes, etc.
21032 (build_method_type_directly): Ditto for method types.
