Separate target-specific initialization from general
back-end initialization.
* toplev.c (init_alignments): New, split out from...
(process_options): ...here.
(backend_init_target): New, split out from...
(backend_init): ...here.
(lang_dependent_init_target): New, split out from...
(lang_dependent_init): ...here.
(target_reinit): New.
* toplev.h (target_reinit): Declare.
* expr.c (init_expr_target): Renamed from init_expr_once, since it
now can be called more than once. Update comments.
* expr.h (init_expr_target): Likewise.
* alias.c (init_alias_target): Renamed from init_alias_once, since it
now can be called more than once. Explicitly zero
static_reg_base_value.
* emit-rtl.c (init_emit_regs): New, split out from...
(init_emit_once): Here.
* regclass.c (initial_fixed_regs, initial_call_used_regs): Make
non-const, so that changes from command-line arguments can overwrite
values provided by the static initializers.
(initial_call_really_used_regs): New, used similarly to the above.
(initial_reg_names): Likewise.
(last_mode_for_init_move_cost): Promoted function-local static to
file-scope static to make it accessible outside init_move_cost.
(init_reg_sets): Do not initialize fixed_regs and call_used_regs yet.
Do not initialize inv_reg_alloc_order yet, either. Do initialize
reg_names since it is needed for parsing command-line options.
(init_move_cost): Use last_mode_for_init_move_cost instead of
function-local static.
(init_reg_sets_1): Initialize fixed_regs, call_used_regs, and
call_really_used_regs now. Reinitialize reg_names. Also
initialize inv_reg_alloc_order. Zero reg_class_subunion and
reg_class_superunion. Clear losing_caller_save_reg_set.
Preserve global registers if called more than once. Reset
move cost, may_move_in_cost, may_move_out_cost, and
last_mode_for_init_move_cost.
(init_reg_modes_target): Renamed from init_reg_modes_once, since it
can now be invoked more than once. Update comments.
(init_regs): Update comments.
(fix_register): Update initial_fixed_regs, initial_call_used_regs,
and initial_call_really_used_regs, instead of the non-initial
variables. This allows us to save the command-line register settings
after target reinitialization.
(init_reg_autoinc): Zero forbidden_inc_dec_classes.
* rtl.h (init_emit_regs): Declare.
(init_reg_modes_target, init_alias_target): Renamed as described
above.
* reload1.c (init_reload): Update comments.
* optabs.c (init_optabs): Likewise.
* cfgloopanal.c (init_set_costs): Explicitly zero target_avail_regs.
