[non-stop] 07/10 non-stop inferior control

- Subject: [non-stop] 07/10 non-stop inferior control
This patch adds the base inferior control support for non-stop mode.
In non-stop mode, each thread is handled individually. ÂIt should
behave close to having a separate debugger attached to each thread.
To accomplish that, as soon as we have an event, we context switch
to it, and go on handling it. ÂThe cases of hiting a breakpoint
in another thread while we're stepping don't need to be handled
specially, as each thread will have its own stepping state.
Another difference in non-stop mode, is that exec commands
apply only to the selected thread; the target is never told
to resume all threads -- much like with scheduler locking
on.
It is also needed to have support to interrupt/suspend a simple
thread so a new target_stop_ptid method was added to request
the target to interrupt a single thread.
Several checks have been added so GDB doesn't try to do
things with running threads, which don't make sense,
like asking for the current PC of an executing thread.
"info threads" now shows "(running)" instead of info on the
selected frame, on running threads. ÂMI support will be
added on top.

2008-06-15 Pedro Alves <pedro@codesourcery.com>
* infrun.c (resume): In non-stop mode, always resume just one
thread.
(proceed): Don't call prepare_to_proceed in non-stop mode.
(fetch_inferior_event): In non-stop mode, switch context before
handling the event.
(error_is_running, ensure_not_running): New.
(handle_inferior_event): In non-stop mode: Mark only the event
thread as stopped. Require that the target module manages adding
threads to the thread list. Don't switch to
infwait_thread_hop_state.
(normal_stop): Only mark not-running if inferior hasn't exited.
In non-stop mode, only mark the event thread.
* thread.c:Include "cli/cli-decode.h".
(print_thread_info): Don't read from a running thread.
Output "(running)" if thread is running.
(switch_to_thread): Don't read stop_pc if thread is executing.
(do_restore_current_thread_cleanup): Don't write to a running
thread.
(thread_apply_all_command): Don't read from a running thread. In
non-stop mode, do a full context-switch instead of just switching
threads.
(thread_apply_command): In non-stop mode, do a full context-switch
instead of just switching threads.
(do_captured_thread_select): Likewise. Inform user if selected
thread is running.
(_initialize_thread): Mark "info threads" and "thread" and
async_ok.
* inf-loop.c (inferior_event_handler): In non-stop mode, don't
unregister the target from the event loop.
* infcmd.c (continue_command, step_1, jump_command)
(signal_command): Ensure the selected thread isn't running.
(interrupt_target_command): In non-stop mode, interrupt only the
selected thread.
* inferior.h (error_is_running, ensure_not_running): Declare.
* target.h (struct target_ops): Add to_stop_ptid member.
(target_stop_ptid): Define.
* target.c (update_current_target): Inherit to_stop_ptid. Default
to_stop_ptid to target_ignore.
(debug_to_stop_ptid): New.
(debug_to_rcmd): Set to_stop_ptid.
* Makefile.in (thread.o): Update.
