6392 2007-01-02  Douglas Gregor  <doug.gregor@gmail.com>
6394         * c-common.c (c_common_nodes_and_builtins): Since variants of
6395         void_type_node get built before it is given a name, we need to
6396         give those variants the name, too.
6397         (complete_array_type): We need to work with the canonical main

6403         alignment of a type for which we're building an array, we end up

6405         * tree.c (make_node_stat): When we build a new type, it is its
6406         own canonical type.
6407         (build_type_attribute_qual_variant): When building an attribute
6408         variant, its canonical type is the non-attribute variant. However,

6410         use structural equality checks for this type.
6411         (build_qualified_type): A qualified type is not equivalent to its
6412         unqualified variant; set the canonical type appropriately.

6414         another type, the new type is its own canonical type.

6420         also build a canonical type reference.
6421         (build_index_type): When we can't hash an index type (e.g.,
6422         because its maximum value is negative), the index type requires
6423         structural equality tests.
6424         (build_array_type): Build the canonical form of an array type.
6425         (build_function_type): Function types require structural equality,
6426         because they contain default arguments, attributes, etc.

6428         (build_offset_type): Build the canonical offset type.
