This patch adds the support of aarch64-linux process record and reverse debugging. The implementation is similar to ARM's counterpart. 2015-05-26 Omair Javaid <omair.javaid@linaro.org> Yao Qi <yao.qi@linaro.org> * aarch64-linux-tdep.c: Include linux-record.h and record-full.h. (struct linux_record_tdep aarch64_linux_record_tdep): Declare. (aarch64_syscall): New enum. (aarch64_canonicalize_syscall): New function. (aarch64_all_but_pc_registers_record): New function. (aarch64_linux_syscall_record): New function. (aarch64_linux_init_abi): Install AArch64 process record handler. Update to handle syscall recording. * aarch64-tdep.c: Include record.h and record-full.h. (submask, bit, bits, REG_ALLOC, MEM_ALLOC): New macros. (struct aarch64_mem_r): Define. (aarch64_record_result): New enum. (struct insn_decode_record): Define. (insn_decode_record): New typedef. (aarch64_record_data_proc_reg): New function. (aarch64_record_data_proc_imm): New function. (aarch64_record_branch_except_sys): New function. (aarch64_record_load_store): New function. (aarch64_record_data_proc_simd_fp): New function. (aarch64_record_asimd_load_store): New function. (aarch64_record_decode_insn_handler): New function. (deallocate_reg_mem): New function. (aarch64_process_record): New function. * aarch64-tdep.h (struct gdbarch_tdep) <aarch64_syscall_record>: New field. (aarch64_process_record): New extern declaration. * configure.tgt: Add linux-record.o to gdb_target_obs. * linux-record.h (struct linux_record_tdep) <arg7>: New field.
