22 * toplev.h (target_reinit): Declare.
23 * expr.c (init_expr_target): Renamed from init_expr_once, since it
24 now can be called more than once. Update comments.
25 * expr.h (init_expr_target): Likewise.
26 * alias.c (init_alias_target): Renamed from init_alias_once, since it

53 (fix_register): Update initial_fixed_regs, initial_call_used_regs,
54 and initial_call_really_used_regs, instead of the non-initial
55 variables. This allows us to save the command-line register settings
56 after target reinitialization.
57 (init_reg_autoinc): Zero forbidden_inc_dec_classes.
58 * rtl.h (init_emit_regs): Declare.
59 (init_reg_modes_target, init_alias_target): Renamed as described
