14 2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
16 * c-common.c(c_common_nodes_and_builtins): Since variants of
17 void_type_node get built before it is given a name, we need to
18 give those variants the name, too.
19 (complete_array_type): We need to work with the canonical main
20 type of the array, from which we will build the qualified version.
21 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
22 * print-tree.c (print_node): Display canonical type information
24 * stor-layout.c (layout_type): When we don't know the
25 alignment of a type for which we're building an array, we end up
26 guessing wrong, so make the type require structural equality.
27 * tree.c (make_node_stat): When we build a new type, it is its
29 (build_type_attribute_qual_variant): When building an attribute
30 variant, its canonical type is the non-attribute variant. However,
31 if the attributes are target-dependent and they differ, we need to
32 use structural equality checks for this type.
33 (build_qualified_type): A qualified type is not equivalent to its
34 unqualified variant; set the canonical type appropriately.
35 (build_distinct_type_copy): When building a distinct type from
36 another type, the new type is its own canonical type.
37 (build_variant_type_copy): When building a new type variant, we
38 assume that it is equivalent to the original type.
39 (build_pointer_type_for_mode): When building a pointer type, also
40 build a canonical type pointer.
41 (build_reference_type_for_mode): When building a reference type,
42 also build a canonical type reference.
43 (build_index_type): When we can't hash an index type (e.g.,
44 because its maximum value is negative), the index type requires
45 structural equality tests.
46 (build_array_type): Build the canonical form of an array type.
47 (build_function_type): Function types require structural equality,
48 because they contain default arguments, attributes, etc.
49 (build_method_type_directly): Ditto for method types.
50 (build_offset_type): Build the canonical offset type.
51 (build_complex_type): Build the canonical vector type.
52 (make_vector_type): Build the canonical vector type.
53 * tree.h (TYPE_CANONICAL): New.
54 (TYPE_STRUCTURAL_EQUALITY_P): New.
55 (SET_TYPE_STRUCTURAL_EQUALITY): New.
56 (struct tree_type): Added "canonical" field.

62 parameter for verifying canonical types.
