* c-common.c (c_common_nodes_and_builtins): Since variants of

* stor-layout.c (layout_type): When we don't know the

alignment of a type for which we're building an array, we end up

guessing wrong, so make the type require structural equality.

* tree.c (make_node_stat): When we build a new type, it is its

|
||
(build_type_attribute_qual_variant): When building an attribute
|

variant, its canonical type is the non-attribute variant. However,
|
||
if the attributes are target-dependent and they differ, we need to

||
use structural equality checks for this type.
|
||
(build_qualified_type): A qualified type is not equivalent to its

unqualified variant; set the canonical type appropriately.
|
||
(build_distinct_type_copy): When building a distinct type from

another type, the new type is its own canonical type.
|

(build_variant_type_copy): When building a new type variant, we

assume that it is equivalent to the original type.

(build_pointer_type_for_mode): When building a pointer type, also

||
build a canonical type pointer.
|
||
(build_reference_type_for_mode): When building a reference type,
|
||
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.
