4036 (initial_reg_names): Likewise.
4037 (last_mode_for_init_move_cost): Promoted function-local static to

4040 Do not initialize inv_reg_alloc_order yet, either. Do initialize
4041 reg_names since it is needed for parsing command-line options.

4043 function-local static.

4046 initialize inv_reg_alloc_order. Zero reg_class_subunion and
4047 reg_class_superunion. Clear losing_caller_save_reg_set.
4048 Preserve global registers if called more than once. Reset
4049 move cost, may_move_in_cost, may_move_out_cost, and
4050 last_mode_for_init_move_cost.

4052 can now be invoked more than once. Update comments.

4054 (fix_register): Update initial_fixed_regs, initial_call_used_regs,
4055 and initial_call_really_used_regs, instead of the non-initial
4056 variables. This allows us to save the command-line register settings
4057 after target reinitialization.

28570 * c-common.c (c_common_nodes_and_builtins): Since variants of
28571 void_type_node get built before it is given a name, we need to
28572 give those variants the name, too.
28573 (complete_array_type): We need to work with the canonical main

28578 * stor-layout.c (layout_type): When we don't know the
28579 alignment of a type for which we're building an array, we end up
28580 guessing wrong, so make the type require structural equality.

28582 own canonical type.
28583 (build_type_attribute_qual_variant): When building an attribute
28584 variant, its canonical type is the non-attribute variant. However,
28585 if the attributes are target-dependent and they differ, we need to
28586 use structural equality checks for this type.
28587 (build_qualified_type): A qualified type is not equivalent to its
28588 unqualified variant; set the canonical type appropriately.
28589 (build_distinct_type_copy): When building a distinct type from
28590 another type, the new type is its own canonical type.
28591 (build_variant_type_copy): When building a new type variant, we
28592 assume that it is equivalent to the original type.
28593 (build_pointer_type_for_mode): When building a pointer type, also
28594 build a canonical type pointer.
28595 (build_reference_type_for_mode): When building a reference type,
28596 also build a canonical type reference.
28597 (build_index_type): When we can't hash an index type (e.g.,
28598 because its maximum value is negative), the index type requires
28599 structural equality tests.
28600 (build_array_type): Build the canonical form of an array type.
28601 (build_function_type): Function types require structural equality,
28602 because they contain default arguments, attributes, etc.
