AArch64: Wire through instr_sequence
This patch introduces aarch64_instr_sequence which is a structure similar to IT blocks on Arm in order to track instructions that introduce a constraint or dependency on instruction 1..N positions away from the instruction that opened the block. The struct is also wired through to the locations that require it. gas/ * config/tc-aarch64.c (now_instr_sequence): (*insn_sequence, now_instr_sequence): New. (output_operand_error_record, do_encode): Add insn_sequence. (md_assemble): Update insn_sequence. (try_to_encode_as_unscaled_ldst, fix_mov_imm_insn, fix_insn): Pass insn_sequence. * config/tc-aarch64.h (struct aarch64_segment_info_type): Add insn_sequence. include/ * opcode/aarch64.h (struct aarch64_instr_sequence): New. (aarch64_opcode_encode): Use it. opcodes/ * aarch64-asm.c (aarch64_opcode_encode): Add insn_sequence. * aarch64-dis.c (insn_sequence): New.
