c194fbe18b Implement attach/detach for multi-threaded programs on Linux.
* thread-db.c (keep_thread_db): Adjust comment.
(deactivate_target): Removed.
(thread_db_new_objfile): Don't call deactivate_target.  Implement
guts of deactivate_target inline instead.
(attach_thread): Call ATTACH_LWP unconditionally if defined.
(thread_db_attach): New function.
(thread_db_detach): Don't call deactivate_target.  Do necessary
cleanup inline instead.  Set inferior_ptid to LWP corresponding to
the current user-level thread.
(thread_db_kill): Set inferior_ptid to LWP corresponding to the
current user-level thread.
(thread_db_create_inferior): Deactivate target vector if
KEEP_THREAD_DB is zero.
(thread_db_mourn_inferior): Don't call deactivate_target.  Do
necessary cleanup inline instead.
(init_thread_db_ops): Initialize to_attach field to
thread_db_attach.
* lin-lwp.c (lin_lwp_mourn_inferior): Remove prototype.
(stop_wait_callback): Add prototype.
(init_lwp_list): Add comment about when to re-initialize the LWP
list.
(lin_lwp_attach_lwp): Only call ptrace for cloned processes.
Avoid adding publicates to the LWP list.  Only mark an LWP as
signalled if it doesn't correspond to a cloned process.
(lin_lwp_attach): Add initial process to the LWP list.  Make sure
it's stopped and fake a SIGSTOP.
(detach_callback): New function.
(lin_lwp_detach): Implement.
(lin_lwp_create_inferior): Don't re-initialize LWP list here.
Call child_ops.to_create_inferior directly instead of via
target_beneath local.
(lin_lwp_mourn_inferior): Call child_ops.to_mourn_inferior
directly instead of via target_beneath local.

* thread-db.c (_initialize_thread_db): Add set/show command
	"debug-linux-threads" for debugging output.
	* lin-lwp.c (various): Use global "debug_linux_threads to
	turn on extra debugging output.

	signals, ignore signal zero.

95a856212b * thread-db.c (check_event): Don't report an error if we encounter
a thread creation event for a thread that's already in the thread
list, since that may legitemately happen.  Instead only call
attach_thread if it's not already in the thread list.

bda9cb723c Fix debugging programs statically linked against the thread library.
* thread-db.c: Various comment fixes and additions.
Include "bfd.h", "symfile.h" and "objfiles.h".
(keep_thread_db): New variable.
(find_new_threads_callback): Remove prototype.
(thread_db_find_new_threads): New prototype.
(thread_db_push_target, thread_db_unpush_target): Remove
functions.
(deactivate_target): New function.
(thread_db_new_objfile): If OBJFILE == NULL, force deactivation of
target vector.  Activate target vector directly instead of calling
thread_db_push_target.  Set keep_thread_db if thread library is
detected in the main symbol file.  Only enable thread event
reporting if there actually is a child process.  Likewise for
detecting new threads, done by calling thread_db_find_new_threads
instead of iterating over the threads ourselves.
(thread_db_detach): Call deactivate_target instead of
thread_db_unpush_target.
(thread_db_wait): Bail out early if we're not debugging the
multi-threaded child process yet.
(thread_db_post_startup_inferior): New function.
(thread_db_mourn_inferior): Call deactivate_target instead of
thread_db_unpush_target.
(init_thread_db_ops): Add thread_db_post_startup_inferior to
thread_db_ops.

GET_THREAD_SIGNALS): New defines.

linux-threads.o.  Add proc-service.o, thread-db.o and lin-lwp.o.
* proc-service.c: New file.
* thread-db.c: New file.
* lin-lwp.c: New file.
