During assembly it is correctly encoded as immediate value (imm.value) in parse_operands. During disassembly it is first correctly decoded as immediate value (imm.value) in aarch64_ext_imm called by aarch64_extract_operand, but then erroneously treated as register number (reg.regno) in aarch64_print_operand. This resolves the assembler test case "SME extension (ZERO)" to erroneously fail on s390. On AArch64 - being little-endian - the struct aarch64_opnd_info union fields reg.regno and imm.value share their least-significant bits. On s390 - being big-endian - they do not. opcodes/ PR binutils/31561 * aarch64-opc.c: Treat operand "SME list of ZA tiles" as immediate.
