(mips_optional_operand_p): New function. opcodes/ * mips-formats.h (OPTIONAL_REG, OPTIONAL_MAPPED_REG): New macros. * micromips-opc.c (decode_micromips_operand): Use OPTIONAL_REG and OPTIONAL_MAPPED_REG. * mips-opc.c (decode_mips_operand): Likewise. * mips16-opc.c (decode_mips16_operand): Likewise. * mips-dis.c (print_insn_arg): Handle OP_OPTIONAL_REG. gas/ * config/tc-mips.c (operand_reg_mask, match_operand): Handle OP_OPTIONAL_REG. (mips_ip, mips16_ip): Use mips_optional_operand_p to check for optional operands.
