Simplify assembly and disassembly of extended mnemonics with operands with constant ORed bits: Their instruction template already contains the respective constant operand bits, as they are significant to distinguish the extended from their base mnemonic. Operands are ORed into the instruction template. Therefore it is not necessary to OR the constant bits into the operand value during assembly in s390_insert_operand. Additionally the constant operand bits from the instruction template can be used to mask them from the operand value during disassembly in s390_print_insn_with_opcode. For now do so for non-length unsigned integer operands only. The separate instruction formats need to be retained, as their masks differ, which is relevant during disassembly to distinguish the base and extended mnemonics from each other. This affects the following extended mnemonics: - vfaebs, vfaehs, vfaefs - vfaezb, vfaezh, vfaezf - vfaezbs, vfaezhs, vfaezfs - vstrcbs, vstrchs, vstrcfs - vstrczb, vstrczh, vstrczf - vstrczbs, vstrczhs, vstrczfs - wcefb, wcdgb - wcelfb, wcdlgb - wcfeb, wcgdb - wclfeb, wclgdb - wfisb, wfidb, wfixb - wledb, wflrd, wflrx include/ * opcode/s390.h (S390_OPERAND_OR1, S390_OPERAND_OR2, S390_OPERAND_OR8): Remove. opcodes/ * s390-opc.c (U4_OR1_24, U4_OR2_24, U4_OR8_28): Remove. (INSTR_VRR_VVV0U1, INSTR_VRR_VVV0U2, INSTR_VRR_VVV0U3): Define as INSTR_VRR_VVV0U0 while retaining respective insn fmt mask. (INSTR_VRR_VV0UU8): Define as INSTR_VRR_VV0UU while retaining respective insn fmt mask. (INSTR_VRR_VVVU0VB1, INSTR_VRR_VVVU0VB2, INSTR_VRR_VVVU0VB3): Define as INSTR_VRR_VVVU0VB while retaining respective insn fmt mask. * s390-dis.c (s390_print_insn_with_opcode): Mask constant operand bits set in insn template of non-length unsigned integer operands. gas/ * config/tc-s390.c (s390_insert_operand): Do not OR constant operand value bits.
