4cc1b3f79d * gdbserver/remote-utils.c (write_ok): Write "OK", not "Ok", to
match stubs and protocol spec.
	* gdbserver/remote-utils.c (remote_open): Cast to struct sockaddr
	when passing to function which expects that.

	The following changes aren't quite enough to make things work with
	LynxOS (apprently kernel problems).
	* infrun.c (wait_for_inferior): When resuming new thread, pass pid
	not -1 for remote case.
	* thread.c (info_threads_command): Give error if !target_has_stack.
	* infrun.c (start_remote): Call init_thread_list.
	* thread.c (info_threads_command): Don't call kill for remote
	debugging target.
	* target.c (normal_pid_to_str): Print "thread" not "process" for
	remote.
	* remote.c, gdbserver/*: Add 'H', 'S', and 'C' requests, 'X'
	response, and `thread' part of 'T' response.
	* gdbserver/*: If program exits, send packet to GDB before
	exiting.  Handle termination with a signal the same as exiting
	with an exitstatus.
	* remote.c: Don't try to kill program after getting an 'X'
	response.
	* infrun.c (wait_for_inferior): Add comment about kill versus mourn.

479f0f18d4 * defs.h, infrun.c (wait_for_inferior), top.c: Call
target_wait_hook to allow GUI to handle blocking for inferior.  Call

	* (gdb_stop):  New tcl command to stop the target process.
	* (x_event, gdbtk_wait):  Allow GUI to interrupt gdb out of target
	waits.

	alert GUI of target state changes.
	* (gdbtk_init):  Get the fd of X server for doing async
	notification of X events (via x_event).  Setup new hooks.

	step_resume_breakpoint, use the through_sigtramp_breakpoint, or
	operate on both.
	Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what.
	When setting the frame address of the step resume breakpoint, set
	it to the address for frame *before* the call instruction is
	executed, not after.

199b2450f6 Change the stream argument to _filtered to GDB_FILE *.
Change all references to stdout/stderr to gdb_stdout/gdb_stderr.

Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')

Replaced calls to fopen for output to gdb_fopen.

Added sufficient goo to utils.c and defs.h to make the above work.

The net effect is that stdio output functions are only directly used
in utils.c.  Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.

In the near future, GDB_FILE will stop being equivalant to FILE.

The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior.  The testsuite doesn't notice anything
like this, though.

Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code.  All output from commands
should go to a GDB_FILE.

Target-specific code can still use stdio directly to communicate with
targets.

c0c14c1e8d * infrun.c (wait_for_inferior): Clean up comments which were at
the top of the file, making them more concise and moving them with

branch targets to compute target address using const from previous
	instruction if necessary.

	INSTRUCTION_NULLIFIED, which can tell if the instruction pointed

	* (just before step_over_function:):  Use stop_func_start, not
	stop_pc when checking for the existance of line number info.
	stop_func_start will reflect the proper address of the target
	routine, not of the stub that we may be traversing to get there.
	* tm-hppa.h:  define SKIP_TRAMPOLINE_CODE and IN_SOLIB_TRAMPOLINE
	to deal with the stubs that PA compilers sometimes stick between
	callers and callees.  Also, define FLAGS_REGNUM for access to the
	`flags' pseudo-reg.

	* Define struct unwind_table_entry.
	* valops.c (call_function_by_hand):  Add another arg to
	FIX_CALL_DUMMY (under #ifdef GDB_TARGET_IS_HPPA).  Why is this
	necessary?

cc221e76d6 Many changes to procfs.c, mostly to expand the "info proc" command and to
fix a couple of small bugs.  Changes to other files mostly to fix minor
things pointed out by the SGI compiler.  See ChangeLog for complete details.
