* mips.h (mips_pcrel_operand): Inherit from mips_int_operand. (mips_int_operand_min, mips_int_operand_max): New functions. (mips_decode_pcrel_operand): Use mips_decode_int_operand. opcodes/ * mips-formats.h (PCREL): Reorder parameters and update the definition to match new mips_pcrel_operand layout. (JUMP, JALX, BRANCH): Update accordingly. * mips16-opc.c (decode_mips16_operand): Likewise. gas/ * config/tc-mips.c (match_int_operand): Use mips_int_operand_min and mips_int_operand_max. (mips16_immed_operand, mips16_immed_operands, MIPS16_NUM_IMMED): Delete. (mips16_immed_operand, mips16_immed_in_range_p): New functions. (mips16_immed, mips16_extended_frag): Use them. Use mips_int_operand instead of mips16_immed_operand.
