28 * expr.c (init_expr_target): Renamed from init_expr_once, since it
29 now can be called more than once. Update comments.
30 * expr.h (init_expr_target): Likewise.
31 * alias.c (init_alias_target): Renamed from init_alias_once, since it
32 now can be called more than once. Explicitly zero

35 (init_emit_once): Here.
36 * regclass.c (initial_fixed_regs, initial_call_used_regs): Make
37 non-const, so that changes from command-line arguments can overwrite
38 values provided by the static initializers.
39 (initial_call_really_used_regs): New, used similarly to the above.
40 (initial_reg_names): Likewise.

47 function-local static.
48 (init_reg_sets_1): Initialize fixed_regs, call_used_regs, and

57 (init_regs): Update comments.
58 (fix_register): Update initial_fixed_regs, initial_call_used_regs,
59 and initial_call_really_used_regs, instead of the non-initial
60 variables. This allows us to save the command-line register settings
61 after target reinitialization.
