include/opcode/
* 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.
