+
+	* Makefile.am (AM_CFLAGS): Add '-Wall'.
+	* Makefile.in: Update.
+
+2004-10-26  Jim Blandy  <jimb@redhat.com>
+
+	Add an architecture object to the Unix server.
+	* arch.h: New header file.
+	* server.h (struct arch): New forward struct declaration.
+	(struct child_process): Add an 'arch' member to the process.
+	* thread-db.c: #include arch.h.
+	* linux-target.c: #include arch.h.
+	(allocate_empty_arch): New function.
+	(x86_make_arch): New function.
+	(MAKE_ARCH): New #definition.
+	(linux_attach): Initialize process's architecture.
+
+	Provide arch-independent framework for breakpoints.
+	* server.h (struct arch_bp_table): New forward struct declaration.
+	(struct child_process): New member: 'breakpoint_table'.
+	* linux-target.c (linux_attach): Initialize process's breakpoint
+	table, if the architecture defines a breakpoint table constructor.
+	* arch.h (struct arch): Add fields pointing to breakpoint functions.
+
+	Provide a module implementing breakpoints for architectures that
+	support a simple software breakpoint model ("patch these bytes
+	into the instruction stream").
+	* stock-breakpoints.h, stock-breakpoints.c: New files.
+	* linux-target.c: If STOCK_BREAKPOINTS is #defined, then #include
+	"stock-breakpoints.h".
+	* Makefile.am (EXTRA_rda_SOURCES): Add stock-breakpoints.c.
+	* Makefile.in: Updated.
+
+	Define x86 breakpoint functions using the stock-breakpoints.c
+	model.
+	* configure.in: When configuring for an x86 target, include
+	stock-breakpoints.o in the mix, and #define STOCK_BREAKPOINTS.
+	* configure: Regenerated.
+	* config.in (STOCK_BREAKPOINTS): Provide #definition template.
+	* linux-target.c (stock_table_to_x86, x86_table_to_stock,
+	stock_bp_to_x86, x86_bp_to_stock, x86_make_bp_table, x86_set_bp,
+	x86_delete_bp, x86_bp_hit_p): New functions.
+	(x86_make_arch): Register the latter four as our breakpoint
+	methods.
+
+	Use the libthread_db event interface to communicate with the
+	thread library, if the old signal-based interface is not
+	supported.
+	* thread-db.c: #include <assert.h>.
+	(thread_db_event_str): New function.
+	(get_target_int_by_name, set_target_int_by_name, get_thread_signals)
+	(cancel_signal, restart_signal, debug_signal): Move these to just
+	before thread_db_dlopen; get_thread_signals is a subroutine of that.
+	(using_thread_db_events, create_notification, death_notification,
+	create_event_breakpoint, death_event_breakpoint): New global vars.
+	(get_event_notification, set_event_breakpoint)
+	(insert_thread_db_event_breakpoints)
+	(delete_thread_db_event_breakpoints, request_thread_db_events)
+	(hit_thread_db_event_breakpoint): New functions.
+	(thread_db_open): Call get_thread_signals, and if that fails, call
+	request_thread_db_events.
+	(struct event_list): Add 'thread_db_event' member.
+	(add_pending_event): Initialize it.
+	(delete_pending_event, handle_thread_db_events): New functions.
+	(find_new_threads_callback): If we're using the event interface,
+	enable event reporting on each new thread we find.
+	(select_pending_event): Return a value to indicate whether we
+	selected any event at all.
+	(continue_all_threads): Send a restart signal only if we're using
+	the signal-based interface.
+	(thread_db_check_child_state): If we're using the libthread_db
+	event interface to communicate with the inferior thread library,
+	check for those events here.  If select_pending_event says it
+	didn't find anything interesting, that means we consumed all the
+	reportable events; continue the program silently.
+	* ptrace-target.c: #include <sys/types.h> and <linux/unistd.h>.
+	(tkill): Generate code for this syscall.
+	(stop_lwp): Use tkill instead of kill.
+
+	* thread-db.c (thread_db_check_child_state): Call stop_all_threads
+	before calling update_thread_list, so RDA will have to compete for
+	CPU with fewer running threads.
+	
+	* thread-db.c (wait_all_threads): Move calls to
+	select_pending_event and send_pending_signals from here...
+	(thread_db_check_child_state): To here.
+
+	* thread-db.c (ignore_thread_signal): New function.
+	(thread_db_check_child_state): Call it, instead of writing it out.
+
+	* thread-db.c (thread_db_open): Return 0 on success, -1 on
+	failure, like most of the other int-valued functions in this file,
+	and like most system calls.
+
+	* thread-db.c (struct gdbserv_thread): Doc fixes.
+
+	* thread-db.c: #include "gdbserv-utils.h", to get prototypes for
+	the 'struct gdbserv_reg' manipulation functions.
+	
+	* thread-db.c (thread_db_noisy): Initialize to 1.
+
+	* thread-db.c (thread_debug_name): New function.
+	(find_new_threads_callback): If noisy, report new threads.
+	(stop_thread): If noisy, report stopping threads.
+	(select_pending_event): If noisy, report what we selected.
+	(wait_all_threads): If noisy, report before each thread we wait
+	for.
+
+	* thread-db.c (stop_all_threads): Doc fixes.
+	
+	* aclocal.m4: Regenerated.
+
+2004-10-20  Jim Blandy  <jimb@redhat.com>
+
+	Use the libthread_db 'td_symbol_list' function to look up all the
+	symbols libthread_db will need when invited to by GDB.
+	* thread-db.c (add_symbol_to_list): Make 'name' argument const.
+	(td_symbol_list_p): New libthread_db function pointer.
+	(thread_db_dlopen): Initialize it.
+	(thread_db_attach): Use td_symbol_list to pre-load our symbol
+	cache with the names of all the symbols libthread_db will ever
+	request.
+
+	* thread-db.c (thread_db_get_gen): There's no reason to try to
+	open a thread agent until we've at least requested values for all
+	the symbols we know about.
+
+	* server.c (usage): Don't include the entire pathname in the usage
+	message.
+
+2004-10-19  Jim Blandy  <jimb@redhat.com>
+
+	* thread-db.c (get_thread_signals): Doc fix.
+
+	* thread-db.c (enum symbol_cache_defined): Move this definition
+	above that of (struct symbol_cache), and give it a name.
+	(struct symbol_cache): Use that enum as the type of 'defined_p', so
+	the debugger will print symbol cache entries more helpfully.
+
+	* ptrace-target.c (ptrace_create_child): Don't use sys_nerr to
+	check that errno is in a valid range.  The use sys_nerr is
+	deprecated on GNU/Linux, and according to the ISO C standard and
+	POSIX, strerror always returns a valid string, even for invalid
+	errno codes.
+
+2004-10-07  Jim Blandy  <jimb@redhat.com>
+
+	* Makefile.am (rda_DEPENDENCIES): Add ../lib/librda.la.

+	(decr_pc_after_break): New function.  Architecture dependent.

+	(thread_db_continue_program): Child is running -- set a flag.
+	(thread_db_singlestep_program): Ditto.
+	(thread_db_check_child_state): Return immediately unles the child

+	can get events from the threads.  Alternately use __WCLONE.
+	(thread_db_get_thread_reg): If thread is not specified, use
