19922 * c-common.c (c_common_nodes_and_builtins): Since variants of
19923 void_type_node get built before it is given a name, we need to
19924 give those variants the name, too.
19925 (complete_array_type): We need to work with the canonical main

19930 * stor-layout.c (layout_type): When we don't know the
19931 alignment of a type for which we're building an array, we end up
19932 guessing wrong, so make the type require structural equality.
19933 * tree.c (make_node_stat): When we build a new type, it is its
19934 own canonical type.
19935 (build_type_attribute_qual_variant): When building an attribute
19936 variant, its canonical type is the non-attribute variant. However,
19937 if the attributes are target-dependent and they differ, we need to
19938 use structural equality checks for this type.
19939 (build_qualified_type): A qualified type is not equivalent to its
19940 unqualified variant; set the canonical type appropriately.
19941 (build_distinct_type_copy): When building a distinct type from
19942 another type, the new type is its own canonical type.
19943 (build_variant_type_copy): When building a new type variant, we
19944 assume that it is equivalent to the original type.
19945 (build_pointer_type_for_mode): When building a pointer type, also
19946 build a canonical type pointer.
19947 (build_reference_type_for_mode): When building a reference type,
19948 also build a canonical type reference.
19949 (build_index_type): When we can't hash an index type (e.g.,
19950 because its maximum value is negative), the index type requires
19951 structural equality tests.
19952 (build_array_type): Build the canonical form of an array type.
19953 (build_function_type): Function types require structural equality,
19954 because they contain default arguments, attributes, etc.
