Simplify using gdb/configure.tgt and gdb/configure.host.
Fix other minor configuration errors.
* gdbserver/low-sparc.c: Fix compile error.
* gdbserver/remote-utils.c: Eliminate assumption that registers
and addresses are four bytes. Fix minor compile errors and warnings.

for starting inferior processes to call new function start_inferior.
Eliminate assumption that registers and addresses are four bytes.

warnings.
* gdbserver/low-sim.c: New file to mate gdbserver with simulators.

in moving such support from host to target makefile fragments.

* remote.c (remote_read_bytes): Fix aborts on larger packets.
* config/i386/linux.mh (GDBSERVER_DEPFILES, GDBSERVER_LIBS):
Define.
* stabsread.c (define_symbol): If register value is too large,
tell what it is and what max is.
* gdbserver/Makefile.in (SFILES): Add low-hppabsd.c.
* config/hppabsd.mh (XDEPFILES): Add ser-tcp.o
(GDBSERVER_DEPFILES): Add low-hppabsd.o
* config/hppaosf.mh: LIkewise.
Needed this for the gdbserver framework development. Trying to avoid doing
development work on lynx for the obvious reasons.
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.
* m68k-tdep.c (m68k_saved_pc_after_call): Get rid of
GDB_TARGET_IS_SUN3. Use more general SYSCALL_TRAP macro.
* config/m68k/m68klynx.mh (NATDEPFILES): Remove exec.o (it's
already in TDEPFILES).
* config/m68k/tm-m68k.h (SAVED_PC_AFTER_CALL): Use
m68k_saved_pc_after_call.
* Remove all Sun3 specific stuff.
* (FIX_CALL_DUMMY): Cast arg to bfd_putb32 to unsigned char *.
* config/m68k/tm-m68klynx.h: Define SYSCALL_TRAP as trap #10.
Disable REMOTE_BREAKPOINT mechanism.
* config/m68k/tm-sun3.h: Get rid of GDB_TARGET_IS_SUN3.
* Protect from multiple includion.
* Move Sun3 specific stuff from tm-m68k.h to here.
* Define SYSCALL_TRAP as trap #0.
* Remove def of SAVED_PC_AFTER_CALL (now in tm-m68k.h).
* gdbserver/low-lynx.c: Redo all register store/fetch stuff to
make it portable for 386 and 68k.
GDBSERVER_DEPFILES. Also remove much (but not all that could be
removed) crud inherited from gdb Makefile.in.
* config/i386/i386lynx.mh, config/sparc/sun4os4.mh: Define GDBSERVER_*.
* gdbserver/README: Say it works on Sun and change configuration
instructions slightly.
* gdbserver/remote-inflow.c (create_inferior): Fix comments, and
error msg. Setup seperate process group for child.
* (write_inferior_memory): Sleep for 1 second and retry on ptrace
failure.
* gdbserver/remote-gutils.c: Remove lots of unused functions and
variables.
* gdbserver/remote-inflow.c: Remove lots of unused variables and
#includes. Also, use PTRACE_* symbols instead of constants.
(mywait): Surround calls to wait() with enable/disable_async_io()
so that we can be interrupted from GDB while waiting for the
child. Also, handle child exit more gracefully.
* gdbserver/remote-server.c: Remove lots of unused variables.
Move all extern defs into server.h. Redo main loop so that
failure from getpkt() causes communications to be re-established.
Fix 'k' command so that it restarts the child.
* gdbserver/remote-utils.c: Remove lots of unloved vars and
subrs. Move many extern decls into server.h. (remote_open): For
tcp, seperate usage of proto fd from connected fd. Close proto
fd after getting connection. (putpkt/getpkt): Pay attention to
errors when reading/writing. Report these to the caller. New
routines input_interrupt/enable_async_io/disable_async_io to make
it possible to get an I/O interrupt when data arrives from the
comm link.
* serial.h: New file to contain common defs for all remote files.
* gdbserver/remote-inflow{-sparc}.c (create_inferior): Don't use a
shell when running the child, as args have been expanded by the
time we get here. Simplify calling convention.
* gdbserver/remote-server.c (main): Use new calling convention
for create_inferior, remove defunct code for coalescing argv.
Remove extra calls to mywait(), as we no longer have to wade
through a shell.
* defs.h (memcmp): Add decl for memcmp to #ifndef MEM_FNS_DECLARED.
* findvar.c (write_register): See if we are writing back the same
value that's already in the register. If so, don't bother.
* remote.c (putpkt, getpkt): Improve handling of communication
problems.
* ser-go32.c: Prototype it to death. Update serial_ops and add
dummy routines where appropriate.
* ser-tcp.c: New module to implement serial I/O via TCP
connections.
* ser-unix.c: Clean up getting/setting of tty state. Get rid of
SERIAL_RESTORE, add SERIAL_{GET|SET}_TTY_STATE interfaces.
* serial.c: Add start of support for connect command.
(serial_open): Distinguish between tcp and local devices.
* serial.h (struct serial_ops): Get rid of restore, add
get_tty_state and set_tty_state. Define protoypes and macros for
this mess.
* gdbserver/remote-utils.c: Add tcp support. (readchar): Do
some real buffering. Handle error conditions gracefully.
* gdbserver/remote-inflow-sparc.c: Update to remote-inflow.c
(Lynx), remove lots of cruft.
