simply save encode this fact as the process group and return
success rather than an error.
(set_tty_state): if process group is -1, do not reset the
process group.
(hardwire_reachar): comment change.
* nindy-share/*, remote-nindy.c: Extensive hacking to make it
conform to GDB conventions like using memcpy not bcopy, serial.h,
etc. This is to make it host on Solaris, AIX, etc.
* Makefile.in: Reflect removed nindy-share files.
<memory.h>.
Include <malloc.h> rather than declaring malloc functions ourself.
* ser-unix.c (set_tty_state): Don't ignore errors setting process
group.
* inflow.c (terminal_inferior): If attach_flag set, ignore errors
from set_tty_state.
* signals.h: Don't undefine signals anymore.
* main.c: Use job_control from serial.h.
* fork-child.c (fork_inferior): Use gdb_setpgid.
* serial.h, ser-unix.c, ser-go32.c: Provide gdb_setpgid.
* utils.c (quit): Use current_target->to_terminal_ours to figure
out whether we care about lack of job control, rather than __GO32__.
* utils.c: Include serial.h not terminal.h
(quit): Use job_control not TIOCGPGRP.
* terminal.h: Don't undefine TIOCGPGRP.
* serial.h, ser-unix.c, ser-go32.c, ser-tcp.c: Add SERIAL_FLUSH_OUTPUT.
* utils.c (quit): Use it.
* serial.h: Add SERIAL_UN_FDOPEN.
* utils.c (quit): Use it.
* ser-unix.c: Add process group to ttystate.
[HAVE_SGTTY]: Add tchars, ltchars, and lmode to ttystate.
* inflow.c: Include serial.h not terminal.h.
Use serial.h stuff to replace most of the maze of #ifdef's.
* inflow.c, main.c, inferior.h: make gdb_has_a_terminal a function.
* serial.h: Document SERIAL_SET_TTY_STATE as being immediate.
* ser-unix.c: Use TIOCSETN not TIOCSETP so it is true.
* serial.h, ser-unix.c, ser-go32.c, ser-tcp.c:
Add SERIAL_PRINT_TTY_STATE, SERIAL_NOFLUSH_SET_TTY_STATE, and
SERIAL_SET_PROCESS_GROUP.
* inflow.c: Use them.
* config/xm-svr4.h, config/rs6000/xm-rs6000.h, config/sparc/sun4os4.h:
Define HAVE_TERMIOS.
* Various: Remove all use of TIOC*_BROKEN.
clarification. Also add prototypes for some new functions.
* (remote_wait): Better error reporting for 'T' responses.
* ser-go32.c (strncasecmp): Make str1 & str2 be const.
* (dos_async_init): Make usage message reflect requested port #.
* ser-tcp.c (tcp_open): Terminate hostname properly to prevent
random hostname lookup failures. Add nicer message for unknown
host error. (wait_for): Wake up in case of exceptions. Also,
restart select() if we got EINTR.
* ser-unix.c (wait_for): Restart select() if we got EINTR.
* serial.c: (serial_close): Clean up code.
* 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.
constants with slightly more portable definitions (still depends
on 2's complement arithmetic though).
* config/i386/nm-linux.h: Define NO_SYS_REG_H for no <sys/reg.h>.
* i386v-nat.c (sys/reg.h): Conditionalize include on
NO_SYS_REG_H. Linux doesn't have <sys/reg.h>.
* ser-unix.c (termio.h): Include <termio.h> like other files that
include termio.h, not <sys/termio.h> which may not exist (on
linux for example).
(putpkt, getpkt): Use new return codes for SERIAL_READCHAR.
* ser-go32.c: Return -1 on most failures, 0 on most successes,
and use new return codes for go32_readchar().
* ser-unix.c: Ditto. Also, move error handling up to caller for
SERIAL_SETBAUDRATE().
* serial.c (serial_open): Internal call, not SERIAL_OPEN to get
to specific routine.
(serial_close): New routine to wrap around device close routine.
serial.h: Clean & document return values more clearly.
These implement a new serial line interface for talking to remote
targets.
* configure.in: Link ser-hardwire.c to ser-unix.c for all hosts,
EXCEPT go32, which gets ser-go32.c.
* remote.c: Use new serial interface. More remote-xxx's to be
converted later.
* ser-bsd.c, ser-termios.c: Removed.
* serial.c: New. Implements common operations for all serial
types.
* ser-unix.c: New. Unix specific serial operations for various
flavors of Unix (Posix, SysV, BSD).
* serial.h: Generic serial interface defs.
* config/i386/go32.mh, config/i386/i386bsd.h,
config/m68k/apollo68b.mh, config/sparc/sun4os4.mh: Remove
ser-bsd.o from XDEPFILES. All the magic is now handled in
configure.in.
