+ * ppc-dis.c (print_insn_powerpc): Update prototye to use new
+ ppc_cpu_t typedef.
+ (struct dis_private): New.
+ (POWERPC_DIALECT): New define.
+ (powerpc_dialect): Renamed to...
+ (powerpc_init_dialect): This. Update to use ppc_cpu_t and
+ struct dis_private.
+ (print_insn_big_powerpc): Update for using structure in
+ info->private_data.
+ (print_insn_little_powerpc): Likewise.
+ (operand_value_powerpc): Change type of dialect param to ppc_cpu_t.
+ (skip_optional_operands): Likewise.
+ (print_insn_powerpc): Likewise. Remove initialization of dialect.
