32 * c-common.c(c_common_nodes_and_builtins): Since variants of
33 void_type_node get built before it is given a name, we need to
34 give those variants the name, too.
35 (complete_array_type): We need to work with the canonical main
36 type of the array, from which we will build the qualified version.
37 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
38 * print-tree.c (print_node): Display canonical type information
40 * stor-layout.c (layout_type): When we don't know the
41 alignment of a type for which we're building an array, we end up
42 guessing wrong, so make the type require structural equality.
43 * tree.c (make_node_stat): When we build a new type, it is its
45 (build_type_attribute_qual_variant): When building an attribute
46 variant, its canonical type is the non-attribute variant. However,
47 if the attributes are target-dependent and they differ, we need to
48 use structural equality checks for this type.
49 (build_qualified_type): A qualified type is not equivalent to its
50 unqualified variant; set the canonical type appropriately.
51 (build_distinct_type_copy): When building a distinct type from
52 another type, the new type is its own canonical type.
53 (build_variant_type_copy): When building a new type variant, we
54 assume that it is equivalent to the original type.
55 (build_pointer_type_for_mode): When building a pointer type, also
56 build a canonical type pointer.
57 (build_reference_type_for_mode): When building a reference type,
58 also build a canonical type reference.
59 (build_index_type): When we can't hash an index type (e.g.,
60 because its maximum value is negative), the index type requires
61 structural equality tests.
62 (build_array_type): Build the canonical form of an array type.
63 (build_function_type): Function types require structural equality,
64 because they contain default arguments, attributes, etc.
65 (build_method_type_directly): Ditto for method types.
66 (build_offset_type): Build the canonical offset type.
67 (build_complex_type): Build the canonical vector type.
68 (make_vector_type): Build the canonical vector type.
69 * tree.h (TYPE_CANONICAL): New.
70 (TYPE_STRUCTURAL_EQUALITY_P): New.
71 (SET_TYPE_STRUCTURAL_EQUALITY): New.

78 parameter for verifying canonical types.
