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.
