  "message": "aarch64: Enforce P/M/E order for MOPS instructions\n\nThe MOPS instructions should be used as a triple, such as:\n\n       cpyfp [x0]!, [x1]!, x2!\n       cpyfm [x0]!, [x1]!, x2!\n       cpyfe [x0]!, [x1]!, x2!\n\nThe registers should also be the same for each writeback operand.\nThis patch adds a warning for code that doesn\u0027t follow this rule,\nalong similar lines to the warning that we already emit for\ninvalid uses of MOVPRFX.\n\ninclude/\n\t* opcode/aarch64.h (C_SCAN_MOPS_P, C_SCAN_MOPS_M, C_SCAN_MOPS_E)\n\t(C_SCAN_MOPS_PME): New macros.\n\t(AARCH64_OPDE_A_SHOULD_FOLLOW_B): New aarch64_operand_error_kind.\n\t(AARCH64_OPDE_EXPECTED_A_AFTER_B): Likewise.\n\t(aarch64_operand_error): Make each data value a union between\n\tan int and a string.\n\nopcodes/\n\t* aarch64-tbl.h (MOPS_CPY_OP1_OP2_INSN): Add scan flags.\n\t(MOPS_SET_OP1_OP2_INSN): Likewise.\n\t* aarch64-opc.c (set_out_of_range_error): Update after change to\n\taarch64_operand_error.\n\t(set_unaligned_error, set_reg_list_error): Likewise.\n\t(init_insn_sequence): Use a 3-instruction sequence for\n\tMOPS P instructions.\n\t(verify_mops_pme_sequence): New function.\n\t(verify_constraints): Call it.\n\t* aarch64-dis.c (print_verifier_notes): Handle\n\tAARCH64_OPDE_A_SHOULD_FOLLOW_B and AARCH64_OPDE_EXPECTED_A_AFTER_B.\n\ngas/\n\t* config/tc-aarch64.c (operand_mismatch_kind_names): Add entries\n\tfor AARCH64_OPDE_A_SHOULD_FOLLOW_B and AARCH64_OPDE_EXPECTED_A_AFTER_B.\n\t(operand_error_higher_severity_p): Check that\n\tAARCH64_OPDE_A_SHOULD_FOLLOW_B and AARCH64_OPDE_EXPECTED_A_AFTER_B\n\tcome between AARCH64_OPDE_RECOVERABLE and AARCH64_OPDE_SYNTAX_ERROR;\n\ttheir relative order is not significant.\n\t(record_operand_error_with_data): Update after change to\n\taarch64_operand_error.\n\t(output_operand_error_record): Likewise.
