4062 * emit-rtl.c (init_emit_regs): New, split out from...
4063 (init_emit_once): Here.
4064 * regclass.c (initial_fixed_regs, initial_call_used_regs): Make

4086 (fix_register): Update initial_fixed_regs, initial_call_used_regs,
4087 and initial_call_really_used_regs, instead of the non-initial
4088 variables. This allows us to save the command-line register settings
4089 after target reinitialization.

28602 * c-common.c (c_common_nodes_and_builtins): Since variants of
28603 void_type_node get built before it is given a name, we need to
28604 give those variants the name, too.
28605 (complete_array_type): We need to work with the canonical main

28610 * stor-layout.c (layout_type): When we don't know the
28611 alignment of a type for which we're building an array, we end up
28612 guessing wrong, so make the type require structural equality.
28613 * tree.c (make_node_stat): When we build a new type, it is its
28614 own canonical type.
28615 (build_type_attribute_qual_variant): When building an attribute
28616 variant, its canonical type is the non-attribute variant. However,
28617 if the attributes are target-dependent and they differ, we need to
28618 use structural equality checks for this type.
28619 (build_qualified_type): A qualified type is not equivalent to its
28620 unqualified variant; set the canonical type appropriately.
28621 (build_distinct_type_copy): When building a distinct type from
28622 another type, the new type is its own canonical type.
28623 (build_variant_type_copy): When building a new type variant, we
28624 assume that it is equivalent to the original type.
28625 (build_pointer_type_for_mode): When building a pointer type, also
28626 build a canonical type pointer.
28627 (build_reference_type_for_mode): When building a reference type,
28628 also build a canonical type reference.
28629 (build_index_type): When we can't hash an index type (e.g.,
28630 because its maximum value is negative), the index type requires
28631 structural equality tests.
28632 (build_array_type): Build the canonical form of an array type.
28633 (build_function_type): Function types require structural equality,
28634 because they contain default arguments, attributes, etc.
28635 (build_method_type_directly): Ditto for method types.
28636 (build_offset_type): Build the canonical offset type.
