19090 * print-tree.c (print_node): Display canonical type information
19092 * stor-layout.c (layout_type): When we don't know the
19093 alignment of a type for which we're building an array, we end up
19094 guessing wrong, so make the type require structural equality.
19095 * tree.c (make_node_stat): When we build a new type, it is its
19096 own canonical type.
19097 (build_type_attribute_qual_variant): When building an attribute
19098 variant, its canonical type is the non-attribute variant. However,
19099 if the attributes are target-dependent and they differ, we need to
19100 use structural equality checks for this type.
19101 (build_qualified_type): A qualified type is not equivalent to its
19102 unqualified variant; set the canonical type appropriately.
19103 (build_distinct_type_copy): When building a distinct type from
19104 another type, the new type is its own canonical type.
19105 (build_variant_type_copy): When building a new type variant, we
19106 assume that it is equivalent to the original type.
19107 (build_pointer_type_for_mode): When building a pointer type, also
19108 build a canonical type pointer.
19109 (build_reference_type_for_mode): When building a reference type,
19110 also build a canonical type reference.
19111 (build_index_type): When we can't hash an index type (e.g.,
19112 because its maximum value is negative), the index type requires
19113 structural equality tests.
19114 (build_array_type): Build the canonical form of an array type.
19115 (build_function_type): Function types require structural equality,
19116 because they contain default arguments, attributes, etc.
19117 (build_method_type_directly): Ditto for method types.
