From 0f35dbc4d98da6b1e251ac8148a9d20d6276012b Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Mon, 19 Aug 2013 18:57:00 +0000 Subject: include/opcode/ * mips.h (OP_OPTIONAL_REG): New mips_operand_type. (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.
