1452 * expr.h (init_expr_target): Likewise.
1453 * alias.c (init_alias_target): Renamed from init_alias_once, since it
1454 now can be called more than once. Explicitly zero
1455 static_reg_base_value.
1456 * emit-rtl.c (init_emit_regs): New, split out from...
1457 (init_emit_once): Here.
1458 * regclass.c (initial_fixed_regs, initial_call_used_regs): Make
1459 non-const, so that changes from command-line arguments can overwrite
1460 values provided by the static initializers.
1461 (initial_call_really_used_regs): New, used similarly to the above.

1480 (fix_register): Update initial_fixed_regs, initial_call_used_regs,
1481 and initial_call_really_used_regs, instead of the non-initial
1482 variables. This allows us to save the command-line register settings
1483 after target reinitialization.
