9726 2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
9728 * c-common.c (c_common_nodes_and_builtins): Since variants of
9729 void_type_node get built before it is given a name, we need to
9730 give those variants the name, too.
9731 (complete_array_type): We need to work with the canonical main
9732 type of the array, from which we will build the qualified version.
9733 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.

9736 * stor-layout.c (layout_type): When we don't know the
9737 alignment of a type for which we're building an array, we end up
9738 guessing wrong, so make the type require structural equality.
9739 * tree.c (make_node_stat): When we build a new type, it is its
9741 (build_type_attribute_qual_variant): When building an attribute
9742 variant, its canonical type is the non-attribute variant. However,
9743 if the attributes are target-dependent and they differ, we need to
9744 use structural equality checks for this type.
9745 (build_qualified_type): A qualified type is not equivalent to its
9746 unqualified variant; set the canonical type appropriately.
9747 (build_distinct_type_copy): When building a distinct type from
9748 another type, the new type is its own canonical type.
9749 (build_variant_type_copy): When building a new type variant, we
9750 assume that it is equivalent to the original type.
9751 (build_pointer_type_for_mode): When building a pointer type, also
9752 build a canonical type pointer.
9753 (build_reference_type_for_mode): When building a reference type,
9754 also build a canonical type reference.
9755 (build_index_type): When we can't hash an index type (e.g.,
9756 because its maximum value is negative), the index type requires
9757 structural equality tests.
9758 (build_array_type): Build the canonical form of an array type.
9759 (build_function_type): Function types require structural equality,
9760 because they contain default arguments, attributes, etc.
9761 (build_method_type_directly): Ditto for method types.
9762 (build_offset_type): Build the canonical offset type.
9763 (build_complex_type): Build the canonical vector type.
9764 (make_vector_type): Build the canonical vector type.

9774 parameter for verifying canonical types.
