* ppc.h (ppc_cpu_t): New typedef. (struct powerpc_opcode <flags>): Use it. (struct powerpc_operand <insert, extract>): Likewise. (struct powerpc_macro <flags>): Likewise. gas/ * config/tc-ppc.c (ppc_cpu): Use ppc_cpu_t typedef. (ppc_insert_operand): Likewise. (ppc_machine): Likewise. * config/tc-ppc.h: #include "opcode/ppc.h" (struct _ppc_fix_extra <ppc_cpu>): Use ppc_cpu_t typedef. (ppc_cpu): Update extern decl. opcodes/ * 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. * ppc-opc.c (extract_bat, extract_bba, extract_bdm, extract_bdp, extract_bo, extract_boe, extract_fxm, extract_mb6, extract_mbe, extract_nb, extract_nsi, extract_rbs, extract_sh6, extract_spr, extract_sprg, extract_tbr insert_bat, insert_bba, insert_bdm, insert_bdp, insert_bo, insert_boe, insert_fxm, insert_mb6, insert_mbe, insert_nsi, insert_ral, insert_ram, insert_raq, insert_ras, insert_rbs, insert_sh6, insert_spr, insert_sprg, insert_tbr): Change the dialect param to be of type ppc_cpu_t. Update prototype.
