6837 (initial_reg_names): Likewise.
6838 (last_mode_for_init_move_cost): Promoted function-local static to
6839 file-scope static to make it accessible outside init_move_cost.

6841 Do not initialize inv_reg_alloc_order yet, either. Do initialize
6842 reg_names since it is needed for parsing command-line options.
6843 (init_move_cost): Use last_mode_for_init_move_cost instead of
6844 function-local static.
6845 (init_reg_sets_1): Initialize fixed_regs, call_used_regs, and

6847 initialize inv_reg_alloc_order. Zero reg_class_subunion and
6848 reg_class_superunion. Clear losing_caller_save_reg_set.
6849 Preserve global registers if called more than once. Reset
6850 move cost, may_move_in_cost, may_move_out_cost, and
6851 last_mode_for_init_move_cost.

6853 can now be invoked more than once. Update comments.

6855 (fix_register): Update initial_fixed_regs, initial_call_used_regs,
6856 and initial_call_really_used_regs, instead of the non-initial
6857 variables. This allows us to save the command-line register settings
6858 after target reinitialization.

31371 * c-common.c (c_common_nodes_and_builtins): Since variants of

31383 own canonical type.
31384 (build_type_attribute_qual_variant): When building an attribute
31385 variant, its canonical type is the non-attribute variant. However,
31386 if the attributes are target-dependent and they differ, we need to
31387 use structural equality checks for this type.
31388 (build_qualified_type): A qualified type is not equivalent to its
31389 unqualified variant; set the canonical type appropriately.
31390 (build_distinct_type_copy): When building a distinct type from
31391 another type, the new type is its own canonical type.
31392 (build_variant_type_copy): When building a new type variant, we
31393 assume that it is equivalent to the original type.
31394 (build_pointer_type_for_mode): When building a pointer type, also
31395 build a canonical type pointer.
31396 (build_reference_type_for_mode): When building a reference type,
31397 also build a canonical type reference.
31398 (build_index_type): When we can't hash an index type (e.g.,
31399 because its maximum value is negative), the index type requires
31400 structural equality tests.
31401 (build_array_type): Build the canonical form of an array type.
31402 (build_function_type): Function types require structural equality,
31403 because they contain default arguments, attributes, etc.
31404 (build_method_type_directly): Ditto for method types.
31405 (build_offset_type): Build the canonical offset type.
31406 (build_complex_type): Build the canonical vector type.
