[AArch64, Binutils] Add missing TSB instruction
This patch implements the TSB instructions: https://developer.arm.com/docs/ddi0596/f/base-instructions-alphabetic-order/ tsb-csync-trace-synchronization-barrier Since TSB and PSB both use the same (and only) argument "CSYNC", this patch reuses it for TSB. However, the same argument would imply different value for CRm:Op2 which are anyway fixed values, so I have diverted the inserter/extracter function to dummy versions instead of the "hint" version. The operand checker part still uses the existing infratructure for AARCH64_OPND_BARRIER_PSB to make sure the operand is parsed correctly. gas/ChangeLog: 2020-04-20 Sudakshina Das <sudi.das@arm.com> * config/tc-aarch64.c (parse_barrier_psb): Update error messages to include TSB. * testsuite/gas/aarch64/system-2.d: Update -march and new tsb tests. * testsuite/gas/aarch64/system-2.s: Add new tsb tests. * testsuite/gas/aarch64/system.d: Update. opcodes/ChangeLog: 2020-04-20 Sudakshina Das <sudi.das@arm.com> * aarch64-asm.c (aarch64_ins_none): New. * aarch64-asm.h (ins_none): New declaration. * aarch64-dis.c (aarch64_ext_none): New. * aarch64-dis.h (ext_none): New declaration. * aarch64-opc.c (aarch64_print_operand): Update case for AARCH64_OPND_BARRIER_PSB. * aarch64-tbl.h (aarch64_opcode_table): Add tsb. (AARCH64_OPERANDS): Update inserter/extracter for AARCH64_OPND_BARRIER_PSB to use new dummy functions. * aarch64-asm-2.c: Regenerated. * aarch64-dis-2.c: Regenerated. * aarch64-opc-2.c: Regenerated.
