also build a canonical type reference.
(build_index_type): When we can't hash an index type (e.g.,
because its maximum value is negative), the index type requires
structural equality tests.
(build_array_type): Build the canonical form of an array type.
(build_function_type): Function types require structural equality,
because they contain default arguments, attributes, etc.
(build_method_type_directly): Ditto for method types.
(build_offset_type): Build the canonical offset type.
(build_complex_type): Build the canonical vector type.
(make_vector_type): Build the canonical vector type.

2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
* typeck.c (structural_comptypes): Renamed from "comptypes".
(comptypes): Use canonical type information to perform fast type
comparison. When VERIFY_CANONICAL_TYPES, verify that the
canonical type comparison returns the same results as we would see
from the current, structural check. Support COMPARE_STRUCTURAL
when we need structural checks.
* decl.c (typename_compare): Fix comment.
(build_typename_type): TYPENAME_TYPE nodes require structural
equality checks, because they resolve different based on the
current class type.
(make_unbound_class_template): UNBOUND_CLASS_TEMPLATE nodes
require structural equality checks (for now).
(build_ptrmemfunc_type): Build the canonical pointer to member
function type.
(compute_array_index_type): Whenever we build a new index type
to represent the size of an array in a template, we need to mark
this index type as requiring structural equality. This goes for
arrays with value-dependent sizes with the current ABI, or all
arrays with ABI-1.
* tree.c (cplus_array_hash): New.
(struct cplus_array_info): New.
(cplus_array_compare): New.
(cplus_array_htab): New.
(build_cplus_array_type_1): Use a hash table to cache the array
types we build. Build the canonical array type for each array
type.
(cp_build_qualified_type_real): When building a cv-qualified array
type, use the hash table of array types and build canonical array
types as necessary.
(bind_template_template_parm): BOUND_TEMPLATE_TEMPLATE_PARM nodes
use structural equality (for now).
* cp-tree.h (COMPARE_STRUCTURAL): New.
* pt.c (canonical_template_parms): New.
(canonical_type_parameter): New.
(process_template_parm): Find the canonical type parameter.
(lookup_template_class): When we have named the primary template
type, set the canonical type for our template class to the primary
template type. If any of the template arguments need structural
equality checks, the template class needs structural equality
checks.
(tsubst): When reducing the level of a template template
parameter, we require structural equality tests for the resulting
parameter because its template parameters have not had their types
canonicalized. When reducing a template type parameter, find the
canonical reduced type parameter.
(any_template_arguments_need_structural_equality_p): New.

* objc-act.c (objc_build_volatilized_type): Keep track of
canonical types.
