1869 Separate target-specific initialization from general
1870 back-end initialization.
1872 * toplev.c (init_alignments): New, split out from...
1873 (process_options): ...here.
1874 (backend_init_target): New, split out from...
1875 (backend_init): ...here.
1876 (lang_dependent_init_target): New, split out from...
1877 (lang_dependent_init): ...here.
1878 (target_reinit): New.
1879 * toplev.h (target_reinit): Declare.
1880 * expr.c (init_expr_target): Renamed from init_expr_once, since it
1881 now can be called more than once. Update comments.
1882 * expr.h (init_expr_target): Likewise.
1883 * alias.c (init_alias_target): Renamed from init_alias_once, since it
1884 now can be called more than once. Explicitly zero
1885 static_reg_base_value.
1886 * emit-rtl.c (init_emit_regs): New, split out from...
1887 (init_emit_once): Here.
1888 * regclass.c (initial_fixed_regs, initial_call_used_regs): Make
1889 non-const, so that changes from command-line arguments can overwrite
1890 values provided by the static initializers.
1891 (initial_call_really_used_regs): New, used similarly to the above.
1892 (initial_reg_names): Likewise.
1893 (last_mode_for_init_move_cost): Promoted function-local static to
1894 file-scope static to make it accessible outside init_move_cost.

1896 Do not initialize inv_reg_alloc_order yet, either. Do initialize
1897 reg_names since it is needed for parsing command-line options.
1898 (init_move_cost): Use last_mode_for_init_move_cost instead of
1899 function-local static.
1900 (init_reg_sets_1): Initialize fixed_regs, call_used_regs, and
1901 call_really_used_regs now. Reinitialize reg_names. Also
1902 initialize inv_reg_alloc_order. Zero reg_class_subunion and
1903 reg_class_superunion. Clear losing_caller_save_reg_set.
1904 Preserve global registers if called more than once. Reset
1905 move cost, may_move_in_cost, may_move_out_cost, and
1906 last_mode_for_init_move_cost.
1907 (init_reg_modes_target): Renamed from init_reg_modes_once, since it
1908 can now be invoked more than once. Update comments.
1909 (init_regs): Update comments.
1910 (fix_register): Update initial_fixed_regs, initial_call_used_regs,
1911 and initial_call_really_used_regs, instead of the non-initial
1912 variables. This allows us to save the command-line register settings
1913 after target reinitialization.
1914 (init_reg_autoinc): Zero forbidden_inc_dec_classes.
1915 * rtl.h (init_emit_regs): Declare.
