After the previous target_ops/C++ patches are all squashed and merged, this one can go in separately. This patch adjusts all the target methods to return bool instead of int when they're returning a boolean. gdb/ChangeLog: 2018-05-02 Pedro Alves <palves@redhat.com> * target.h (target_ops) <stopped_by_sw_breakpoint, supports_stopped_by_sw_breakpoint, stopped_by_hw_breakpoint, supports_stopped_by_hw_breakpoint, stopped_by_watchpoint, have_continuable_watchpoint, stopped_data_address, watchpoint_addr_within_range, can_accel_watchpoint_condition, can_run, thread_alive, has_all_memory, has_memory, has_stack, has_registers, has_execution, can_async_p, is_async_p, supports_non_stop, always_non_stop_p, can_execute_reverse, supports_multi_process, supports_enable_disable_tracepoint, supports_disable_randomization, supports_string_tracing, supports_evaluation_of_breakpoint_conditions, can_run_breakpoint_commands, filesystem_is_local, can_download_tracepoint, get_trace_state_variable_value, set_trace_notes, get_tib_address, use_agent, can_use_agent, record_is_replaying, record_will_replay, augmented_libraries_svr4_read>: Adjust to return bool. * aarch64-linux-nat.c: All implementations adjusted. * aix-thread.c: All implementations adjusted. * arm-linux-nat.c: All implementations adjusted. * breakpoint.c: All implementations adjusted. * bsd-kvm.c: All implementations adjusted. * bsd-uthread.c: All implementations adjusted. * corelow.c: All implementations adjusted. * ctf.c: All implementations adjusted. * darwin-nat.c: All implementations adjusted. * darwin-nat.h: All implementations adjusted. * exec.c: All implementations adjusted. * fbsd-nat.c: All implementations adjusted. * fbsd-nat.h: All implementations adjusted. * gnu-nat.c: All implementations adjusted. * gnu-nat.h: All implementations adjusted. * go32-nat.c: All implementations adjusted. * ia64-linux-nat.c: All implementations adjusted. * inf-child.c: All implementations adjusted. * inf-child.h: All implementations adjusted. * inf-ptrace.c: All implementations adjusted. * inf-ptrace.h: All implementations adjusted. * linux-nat.c: All implementations adjusted. * linux-nat.h: All implementations adjusted. * mips-linux-nat.c: All implementations adjusted. * nto-procfs.c: All implementations adjusted. * ppc-linux-nat.c: All implementations adjusted. * procfs.c: All implementations adjusted. * ravenscar-thread.c: All implementations adjusted. * record-btrace.c: All implementations adjusted. * record-full.c: All implementations adjusted. * remote-sim.c: All implementations adjusted. * remote.c: All implementations adjusted. * s390-linux-nat.c: All implementations adjusted. * sol-thread.c: All implementations adjusted. * spu-multiarch.c: All implementations adjusted. * target-delegates.c: All implementations adjusted. * target.c: All implementations adjusted. * target.h: All implementations adjusted. * tracefile-tfile.c: All implementations adjusted. * tracefile.c: All implementations adjusted. * tracefile.h: All implementations adjusted. * windows-nat.c: All implementations adjusted. * x86-linux-nat.h: All implementations adjusted. * x86-nat.h: All implementations adjusted.
