1863         for each type.
1864         * stor-layout.c (layout_type): When we don't know the
1865         alignment of a type for which we're building an array, we end up
1866         guessing wrong, so make the type require structural equality.
1867         * tree.c (make_node_stat): When we build a new type, it is its
1868         own canonical type.
1869         (build_type_attribute_qual_variant): When building an attribute
1870         variant, its canonical type is the non-attribute variant. However,
1871         if the attributes are target-dependent and they differ, we need to
1872         use structural equality checks for this type.
1873         (build_qualified_type): A qualified type is not equivalent to its
1874         unqualified variant; set the canonical type appropriately.

1876         another type, the new type is its own canonical type.

1878         assume that it is equivalent to the original type.

1880         build a canonical type pointer.
1881         (build_reference_type_for_mode): When building a reference type,
1882         also build a canonical type reference.
1883         (build_index_type): When we can't hash an index type (e.g.,
1884         because its maximum value is negative), the index type requires
1885         structural equality tests.
1886         (build_array_type): Build the canonical form of an array type.
1887         (build_function_type): Function types require structural equality,
1888         because they contain default arguments, attributes, etc.
1889         (build_method_type_directly): Ditto for method types.
1890         (build_offset_type): Build the canonical offset type.

1901         * doc/invoke.texi (verify-canonical-types): Document --param
1902         parameter for verifying canonical types.
