1999-12-13  Michael Snyder  <msnyder@cleaver.cygnus.com>

        * breakpoint.h (enum bptype): add new BP type bp_thread_event.
        This will be used when a target needs to set an invisible 
        breakpoint to detect events such as thread creation.
        * breakpoint.c (interlan_breakpoint_number): remove ifdefs.
        (create_thread_event_breakpoint): new function.
        (remove_thread_event_breakpoints): new function.

        (update_breakpoints_after_exec): if bp_thread_event breakpoins
        still exist after an exec, delete them.  They'll need to be 
        found and installed anew anyway.
        (print_it_typical): don't announce bp_thread_event breakpoints.
        (print_one_breakpoint): account for new breakpoint type.
        (mention): don't mention invisible bp_thread_event breakpoints.
        (delete_command): don't delete invisible bp_thread_event bp's.

        (child_wait): Use above function to handle debug events.
        (child_create_inferior): Add more intelligent method for running the

1999-11-30  Michael Snyder  <msnyder@cleaver.cygnus.com>

        * infrun.c (handle_inferior_pid): revert 11-29 change: resuming
        a thread other than the current thread with a signal.  Apparently
        target_resume with a specific pid, a specific signal, and no step
        means to continue ALL threads but to only send the signal to one
        (and not, as I had assumed, to continue only the specified thread).
        * i386-linux-nat.c (fill_gregset): guard against invalid input.
        
1999-11-30  Elena Zannoni  <ezannoni@kwikemart.cygnus.com>

        * infcmd.c (step_once): New function. Used to do just one step
        operation.
        (step_1_continuation): New function. Figure out if we need to step
        again before returning control to the user.
        (step_1): If we are in asynchronous mode, don't do the for loop,
        but rather delegate to continuations the task of repeating the
        step operation.

        * utils.c (do_all_continuations): Copy the continuation list aside
        before working on it.

        * target.h (enum inferior_event_type): Add new enum
        INF_EXEC_CONTINUE.

        * inf-loop.c (inferior_event_handler): Handle new case
        INF_EXEC_CONTINUE.

        * infrun.c (fetch_inferior_event): If we are in the middle of a
        'step n' type command, don't say that the execution is complete,
        but that it will have to continue.

1999-11-30  Kevin Buettner  <kevinb@cygnus.com>

        * utils.c (verror): Don't traverse va_list argument twice.  Also,
        removed extraneous va_end() call.

1999-11-29  Michael Snyder  <msnyder@cleaver.cygnus.com>

        * infrun.c (handle_inferior_pid): If a child thread stops on a 
        signal that we are ignoring, and GDB silently resumes the child, 
        resume ALL threads (not just the one that got the signal).  All
        threads are stopped, so all must be resumed.
        (handle_inferior_pid): on detecting a thread context switch, 
        swap infrun_state ONLY if both the old thread and the new one
        are in the thread list.  Otherwise state information will be lost!
        Problem may arise with flaky back-ends.
        
1999-11-29  Elena Zannoni  <ezannoni@kwikemart.cygnus.com>

        * breakpoint.c (bpstat_stop_status): Don't decrease hit_count
        in case of a wp that has not changed.

        * gdbtypes.c (init_simd_type): Make static.

        * configure.in (AC_CHECK_HEADERS): Check for <sys/ioctl.h>.
        * configure, config.h: Re-generate.
        * inflow.c: Include <sys/ioctl.h>

        * i386b-nat.c: Include "gdbcore.h".
        * fork-child.c: Include "command.h".

        * remote.c (remote_cisco_section_offsets,
        remote_start_remote_dummy, store_register_using_P,
        remote_info_process, remote_cisco_open, remote_cisco_close,
        readsocket, readtty, minitelnet, remote_cisco_wait,
        init_remote_async_ops, init_extended_async_remote_ops,

1999-11-01  Fernando Nasser  <fnasser@totem.to.cygnus.com>

        From Grant Edwards <grante@visi.com>:
        * rdi-share/etherdrv.c (fetch_ports): Print out additional TCP/IP
        port information in ethernet driver if the DEBUG flag is set.

        * annotate.c (breakpoints_changed, annotate_ignore_count_change,
        annotate_stopped): Provide annotation for breakpoint ignore_count
        changes but only provide once at annotate_stopped time for
        sucessive ignore_count triggered breakpoint changes, to make GUIs

1999-11-01  Fernando Nasser  <fnasser@totem.to.cygnus.com>

        From Grant Edwards <grante@visi.com>:
        * rdi-share/ardi.c (HandleStoppedMessage): Changed code that
        handles the "stop" message so that unrecognized errors are
        returned as "Error" rather than "NoError".  The old code resulted
        in some error conditions not being reported to the user.

1999-11-01  Fernando Nasser  <fnasser@totem.to.cygnus.com>

        From Grant Edwards <grante@visi.com>:
        * remote-rdi.c (arm_rdi_open): Added a call to Adp_CloseDevice()
        before attempting to open a connection.  This allows the user to
        issue the "target rdi" command multiple times (in case the user
        needs to change options or re-initialize the link).

1999-11-01  Fernando Nasser  <fnasser@totem.to.cygnus.com>

        From Grant Edwards <grante@visi.com>:
        * rdi-share/endian.h: Deleted.  Name clash with
        /usr/include/endian.h. This was causing the wrong  byte order to
        be used by htons() in the RDI Ethernet driver.
        * rdi-share/angel_endian.h: New file.  Replaces the above.
        * rdi-share/ardi.c: Replace include to reflect the above change.

1999-11-01  Fernando Nasser  <fnasser@totem.to.cygnus.com>

        From Grant Edwards <grante@visi.com>:
        * remote-rdi.c (_initialize_remote_rdi): Added command
        rdilogenable. Allows the user to log ADP packets that are
        exchanged between gdb and the target.  Both the raw packets are
        shown and some minimal decoding is attempted. Default state is
        disabled.
        (_initialize_remote_rdi): Added command rdilogfile. Allows the
        user to specify the filename to which the ADP packet log is to be
        written. Default state is "rdi.log".
        (rdilogenable_command): New function. Related to rdilogenable.
        (rdilogfile_command): New function. Related to rdilogfile.
        * rdi-share/devsw.c (openLogFile, closeLogFile,
        DevSW_SetLogEnable, DevSW_SetLogfile, dumpPacket): New
        functions. Implement logging.
        (DevSW_Read): Log if requested.
        (DevSW_Write): Log if requested.
        * rdi-share/devsw.h: Add prototypes for DevSW_SetLogfile and
        DevSW_SetLogEnable.
        * rdi-share/hostchan.c (Adp_SetLogEnable, Adp_SetLogfile): New
        functions.  Related to rdilogenable and rdilogfile.
        * rdi-share/hostchan.h: Add prototypes for the above functions.

1999-11-01  Fernando Nasser  <fnasser@totem.to.cygnus.com>

        From Grant Edwards <grante@visi.com>:
        * remote-rdi.c (arm_rdi_open): Added code to split the arguments
        to the 'target rdi' command at the first space.  The first word is
        passed to Adp_OpenDevice as the device name, the tail is passed as
        the "arguments" parameter.  This allows user specified baud rates
        -- among other things that still need to be documented [e.g. (gdb)
        target rdi /dev/ttyS1 19200]. NB: With very limited testing, the
        ARM Embedded-ICE seems to run at 19.2K (though it is reported to
        be unreliable above 9600), and the EPI Jeeni seems to run at
        38.4K.

1999-11-01  Fernando Nasser  <fnasser@totem.to.cygnus.com>

        From Grant Edwards <grante@visi.com>:
        * remote-rdi.c (_initialize_remote_rdi): Added the boolean
        set/show variable rdiromatzero. Should be set to true if the
        target has ROM at address 0.  If true, then gdb will not tell the
        target to trap fetches to interrupt vectors (which are located at
        address 0).  Using the Angel monitor, attempting to set
        breakpoints in ROM is an error.  Using JTAG debugging of the
        ARM7TDMI, attempting to set more than two breakpoints in ROM is an
        error. Default state is false (vectors will be trapped) -- used to
        be hardwired false.

1999-11-01  Fernando Nasser  <fnasser@totem.to.cygnus.com>

        From Grant Edwards <grante@visi.com>:
        * remote-rdi.c (_initialize_remote_rdi): Added the boolean
        set/show variable rdiheartbeat. This enables or disables ADP
        link-check "heartbeat" packets sent by the host to the target.
        Heartbeat packets can cause both the ARM Embedded-ICE and the EPI
        Jeeni to malfunction: If a heartbeat packet is received by the
        target while it is sending a packet, that packet will be aborted,
        and the ADP protocol engine then gets very confused. Default state
        is off -- used to hardwired on.

1999-10-29  Kevin Buettner  <kevinb@cygnus.com>

        * i386-linux-nat.c (dummy_sse_values): Also define for systems
        without PTRACE_GETXFPREGS.

1999-10-29  Jim Blandy  <jimb@zwingli.cygnus.com>

        Hardware watchpoint fix from Eli Zaretskii <eliz@gnu.org>:
        
        * breakpoint.c (insert_breakpoints): Fetch the value of the
        expression we need to watch.  If it's a lazy memory lvalue, then
        we need to fetch it now, before we start the inferior again.
        (insert_breakpoints, remove_breakpoint, bpstat_stop_status,
        can_use_hardware_watchpoint): Only those values representing
        memory we actually fetched need to be watched.

1999-10-29  Elena Zannoni  <ezannoni@kwikemart.cygnus.com>

        * breakpoint.h (bpstat_print): Return 'enum print_stop_action',

        * gdbtypes.c (init_simd_type): The upper bound to
        create_range_type is inclusive, not exclusive.

        Add preliminary support for the Pentium-III's Streaming SIMD
        Extensions --- specifically, the ability to read the XMM
        registers.
        * Configure.in: Check for PTRACE_GETXFPREGS, and #define
        HAVE_PTRACE_GETXFPREGS if we have it.
        * acconfig.h: Add entry for HAVE_PTRACE_GETXFPREGS.
        * configure, config.in: Regenerated.

        registers and the SSE registers. 
        * i386-linux-nat.c (GETREGS_SUPPLIES, GETFPREGS_SUPPLIES,
        GETXFPREGS_SUPPLIES): New macros.
        (have_ptrace_getxfpregs): New variable.

        store_xfpregs, dummy_sse_values): New functions.
        (fetch_inferior_registers, store_inferior_registers): Use the
        *_SUPPLIES macros to decide how to fetch a given register.  Use
        {fetch,store}_xfpregs and dummy_sse_values to provide access to
        the SSE registers, on systems where they are present.

1999-10-28  Kevin Buettner  <kevinb@cygnus.com>

        * gdbserver/gdbreplay.c (config.h, errno.h): Include.
        (perror_with_name): Don't declare sys_nerr, sys_errlist, or errno
        when STDC_HEADERS is defined.

        gdbserver/low-sun3.c (my_registers): Declare.
        (registers): Changed from array type to pointer type in order
        to match declaration in inferior.h in main gdb sources.
        * gdbserver/server.h (registers): Likewise.
        * gdbserver/remote-utils.c (outreg): Removed declaration of
        registers[].

        * gdbserver/low-linux.c (fetch_register): Changed PTRACE_PEEKUSR to
        PTRACE_PEEKUSER.  [Note the missing 'E'.]

        * gdbserver/low-linux.c (sys/ptrace.h): Move include to
        avoid conflict with #defines coming from <sys/user.h>.
        (sys/reg.h): Only include when HAVE_SYS_REG_H is defined.
        (PTRACE_XFER_TYPE): Provide a default type in case
        the target doesn't define it.
        (fetch_register, read_inferior_memory, write_inferior_memory):
        Use PTRACE_XFER_TYPE instead of int for ptrace() transfers.
        (I386_GNULINUX_TARGET): Use #ifdef with this symbol instead

        here anymore.
        (_initialize_event_loop): Stdin handler is now stdin_event_handler.

        * event-loop.h: (handler_func): Change signature, adding two new
        args.
        (sig_handler_func): New function type. It is the old handler_func.
        (create_async_signal_handler): Update to use sig_handler_func.
        (delete_async_signal_handler): Prototype for new function.

        * event-loop.c: Include "inferior.h".
        (struct file_handler): Add field error, to indicate error
        condition on fd.
        (struct async_signal_handler): Rename type of proc field.
        (add_file_handler): Add exception condition as something select()
        should report.
        (handle_file_event): In case of error on the fd, record this in
        the file_handler structure. Update call to (*proc)() to match new
        signature.
        (gdb_wait_for_event): If select() or poll() return error, report
        this to user.
        (create_async_signal_handler): Change first param type to

        handling.

1999-09-18  Jim Blandy  <jimb@cygnus.com>

        * pa64solib.c (pa64_solib_create_inferior_hook): Remove code which
        tries to set __d_pid; it's not relevant to PA64 shared libraries.

        A psymtab's texthigh element, and a block's endaddr element, are
        the address past the end of the address range, never the address
        of the last byte.  These data structures mean the same thing on
        forty different architectures; there's no reason they should be
        different on HP/UX.
        * symtab.c (find_pc_sect_psymtab): Remove special case for HP/UX.
        (find_pc_sect_symtab): Same.
        * objfiles.c (find_pc_sect_section): Same.

Sat Sep 18 07:13:03 1999  Jeffrey A Law  (law@cygnus.com)

        * hppa-tdep.c (internalize_unwinds): Handle PA64 shared libraries
        correctly

        trampolines.

1999-09-17  Jim Blandy  <jimb@zwingli.cygnus.com>

        * breakpoint.c (permanent_breakpoint_here_p): Delete.
        Accidentally left over from previous changes.

1999-09-17  Jim Blandy  <jimb@cygnus.com>

        * config/pa/tm-hppa64.h (ARGS_GROW_DOWNWARD): Deleted.  There are
        many more differences between the 32- and 64-bit ABI's than the
        direction the arguments grow, so this name is misleading.
        (PA20W_CALLING_CONVENTIONS): Define this instead.
        * config/pa/tm-hppa.h (ARGS_GROW_DOWNWARD): Delete.
        * hppa-tdep.c (hppa_push_arguments): Split into two separate
        functions, depending on whether PA20W_CALLING_CONVENTIONS is
        #defined.  These implement completely separate specifications,
        they don't really share that much code anyway, and this is much
        more readable.  Specifically: leave a 16-byte, not 32-byte, frame
        marker; correctly align objects larger than eight bytes; promote
        all integral scalar arguments smaller than eight bytes to a full
        register width; pad aggregates smaller than eight bytes on the
        right.

        async mode.
        (remote_async_resume, remote_async_detach, remote_async_kill,
        extended_remote_async_create_inferior, remote_async_wait): Ditto.

        * ser-unix.c (hardwire_readchar): When ASYNC, only read a single
        character.
        (ser_unix_readchar): Ditto.  Problems occure with back-to-back
        data from a target.  The ASYNC code can loose the second data
        chunk.

        * serial.c (serial_fdopen): Initialize async_handler and
        async_context.

        (serial_can_async_p): Rename serial_async_p.
        (serial_open): Initialize ASYNC_HANDLER and ASYNC_CONTEXT. Save

        * serial.c (serial_open): Discard leading ``|'' before opening a
        pipe device.
        * ser-pipe.c (pipe_open): Adjust.
        * serial.c (serial_open): Add ``&'' prefix so that
        "async-hardwire" device can be explicitly selected.  Work in
        progress.
        * ser-unix.c: Register "async-hardwire" device.

        we know it is enabled.

        Implement "permanent breakpoints" --- breakpoints that are
        hardwired into the inferior's code.  GDB knows they're there, but

        permanent.

        breakpoint as enabled.
        * infrun.c (SKIP_PERMANENT_BREAKPOINT): Provide default definition.

        * config/pa/tm-hppa.h (hppa_skip_permanent_breakpoint): Declare.

        up symbol's address from minimal symbol table when N_FUN
        address is missing.  Also, make sure this value is used for
        calculating the value of the texthigh field.

1999-09-14  Elena Zannoni  <ezannoni@kwikemart.cygnus.com>

        * event-loop.c (create_file_handler): Increment the total number
        of file descriptors for the poll case, only if this is a new file

        are Linux specific and break non-Linux builds.  This functionality
        will be restored after FP support unification has been achieved.
        * i387-tdep.c (i387_print_register, void i387_float_info):
        Likewise.

Tue Sep  7 08:18:01 1999  Kevin Buettner  <kevinb@cygnus.com>

        * config/i386/tm-linux.h (REGISTER_NAMES): Changed register
        named "foo" to "fopo" which more accurately describes the FPU
        Operand Pointer Offset.  The real reason for this change, of
        course, is that many programmers use $foo as a convenience
        variable and are likely to be unpleasantly surprised to find
        that they're unwittingly changing the state of their ia32 FPU.

        otherwise just decrease the reference count.
        (go32_remove_hw_breakpoint): Only decrease reference count and
        disable the debug register if it is occupied and its access bits
        match those of an instruction breakpoint.
        (go32_insert_hw_breakpoint): Before occupying another debug
        register, look for an already occupied register that defines an
        instruction breakpoint with the same address.  If found, increment
        its reference count.  Call SHOW_DR even if failed to insert a
        breakpoint.

        consideration, make this a CORE_ADDR, like WDB did. 

        Rather than casting every single use of really_free_pendings to

        eh_break_addr, eh_catch_catch_addr, eh_catch_throw_addr,

        * config/i386/tm-linux.h (LINUX_SIGCONTEXT_SIZE): Define.
        (LINUX_SIGCONTEXT_PC_OFFSET): Define.

        stepping over a function call to also handle stepping out of a

        This change reverts some of David Taylor's change of 31 Dec 1998.
        The HP-UX maintainer needs to submit a new change for whatever
        problem the original change was trying to fix.

        * GDB 4.18 released.
        * Makefile.in (VERSION): Bump to 4.18.1.

Thu Apr  8 16:04:34 1999  Andrew Cagney  <cagney@b1.cygnus.com>

        * target.c (target_signal_to_string): check for signal
        number in range; otherwise if the target board returns

        * utils.c (fputs_maybe_filtered): test value of
        pagination_enabled before paginating.

1999-04-02  James Ingham  <jingham@cygnus.com>

        * blockframe.c (get_prev_frame): Remove the redundant
        get_prev_frame_info.  It is now exactly the same as
        get_prev_frame, so there is no reason to have both functions.
        
        * rs6000-tdep.c (rs6000_init_extra_frame_info): 
          frame.h:

          config/a29k/tm-a29k.h: 
          i386-tdep.c:
        Change all references to get_prev_frame_info to get_prev_frame.
        
1999-04-02  Stan Shebs  <shebs@andros.cygnus.com>

        symtab.h, target.c, top.c, typeprint.c, config/nm-gnu.h: Evaporate
        the unused MAINTENANCE_CMDS conditional.

1999-04-02  James Ingham  <jingham@cygnus.com>

        * config/arm/tm-arm.h: (EXTRACT_STRUCT_VALUE_ADDRESS): This needs
        to call extract_address, not just cast the first 4 bytes, since
        the result will be passed to value_at which expects host-byte
        order. 

        * arm-tdep.c (arm_scan_prologue): The prologue_start address was
        directly &'ed with 0x03fffffc, rather than using
        ADDR_BITS_REMOVE.  This would cause inferior function calls to
        report the stack incorrectly on return.


1999-04-02  Keith Seitz  <keiths@cygnus.com>

        * top.c (ui_loop_hook): Change declaration. Now returns an int.

        * ser-unix.c (hardwire_readchar): Enable ui_loop_hook callbacks
        for non-Cygwin builds. Check return status of ui_loop_hook and
        return a timeout if told to detach. Add more documentation.
        * ser-tcp.c (tcp_readchar): Break up timeouts into one second
        intervals and call ui_loop_hook so that other UIs can
        keep up to date. If ui_loop_hook returns non-zero, then
        return SERIAL_TIMEOUT to facilitate detaching from the
        target.
        * remote.c (remote_interrupted_already): Remove.
        (remote_interrupt_twice): Revive.
        (remote_interrupt): Call remote_stop to interrupt the target
        and install remote_interrupt_twice to take more severe
        actions if this fails.
        (remote_stop): Only attempt to stop the target. This separates
        the command line from other UIs.
        * remote-sim.c (gdb_os_poll_quit): Add a call to ui_loop_hook,
        if it is defined.

1999-04-01  Jim Blandy  <jimb@zwingli.cygnus.com>

        * infrun.c (follow_inferior_fork): Add ifdefs around
        SOLIB_REMOVE_INFERIOR_HOOK.

Wed Mar 31 11:39:49 1999  David Taylor  <taylor@ryobi.cygnus.com>

        * valops.c (search_struct_field): revert HP merge change
        to this function -- it causes messages to be printed about
        member class ambiguity when the compiler is happy.
        (search_struct_field_aux): delete -- added as part of HP merge
        change; with aforementioned change it is no longer called.

1999-03-30  Stan Shebs  <shebs@andros.cygnus.com>

        (follow_exec): Ditto, also save run target and re-push instead of
        always pushing child_ops, add ifdefs around SOLIB_RESTART and
        SOLIB_CREATE_INFERIOR_HOOK.
        (wait_for_inferior): Use new globals instead of ifdefing HPUXHPPA,
        always use printf_filtered to report new threads.
        (normal_stop): Ditto.
        * target.h, target.c (find_run_target): New function.
        * config/pa/nm-hppah.h: Define new macros.

1999-03-29  Stan Shebs  <shebs@andros.cygnus.com>

        * top.h: Include setjmp.h here.

        CALL_DUMMY_ADDRESS, CALL_DUMMY_START_OFFSET,
        CALL_DUMMY_BREAKPOINT_OFFSET, CALL_DUMMY_LENGTH,
        PC_IN_CALL_DUMMY): Add ``call_dummy_location'',
        ``call_dummy_length'', ``pc_in_call_dummy'',
        ``call_dummy_start_offset'', ``call_dummy_breakpoint_offset'' to
        multi-arch framework.

        bptype), breakpoint.c (enum insertion_state_t): Strict ISO-C
        doesn't allow trailing comma in enum definition.

        subdir.
        (tui/libtui.a): When recursing, pass down ${FLAGS_TO_PASS}.  And
        don't echo the make command.  This is closer to what the other
        recursions do.
        (HFILES_NO_SRCDIR): add hpread.h
        (COMMON_OBS): add hp-psymtab-read.o, hp-symtab-read.o
        (SFILES): add hp-psymtab-read.c, hp-symtab-read.c add rules for
        the new files.  Remove hpread.c, hpread.o
        (gdb$(EXEEXT)): Depend on the actual tui library, not on a
        fictitious target.  Since the fictitious target never existed,
        make would always relink.
        (tui/libtui.a): Always recurse to make sure the library is up to
        date.

Wed Jan  6 12:05:12 1999  Stan Shebs  <shebs@andros.cygnus.com>

        * remote.c: Pacify --enable-build-warnings, reformat code
        to conform to standards, fix spelling errors.
        (ishex, stubhex, record_currthread, etc): Declare.
        (ishex, stubhex): Declare char arg as int.
        (pack_string): Comment out, never used but possibly useful.
        (threadref_to_int, remote_get_threadinfo, etc): Make static.

Wed Jan  6 11:43:32 1999  David Taylor  <taylor@texas.cygnus.com>

        The following changes were made by Elena Zannoni
        <ezannoni@cygnus.com> and Edith Epstein <eepstein@cygnus.com> as
        part of a project to merge in changes made by HP.

        * c-exp.y: use external flag hp_som_som_object_present to decide
        whether code was compiled by HP's compilers.  Add two new C++
        tokens for true and false.
        (yylex): check for template name is done differently for the
        HP/aCC compiler case.  Change some of the template processing code
        for handling HP aCC templates.  Handle true and false tokens.
        
Tue Jan  5 11:13:36 1999  Michael Snyder  <msnyder@cleaver.cygnus.com>

        * remote.c (record_curthread): Must not modify inferior_pid when
        called from wait_for_inferior.  Instead, if a new thread-id is
        detected, call add_thread.
        (MAGIC_NULL_PID): new macro, use instead of the magic number
        "42000".
        (remote_find_new_threads): if inferior_pid is unknown, get and use
        the current thread id.
        (remote_start_remote): on connecting, attempt to get the current
        thread id for inferior_pid.
        (remote_resume): If pid == -1, then resume any-thread (not the
        current thread specifically).  Also some cosmetic fixups.
        
        * thread.c (info_threads_command): don't initialize current_pid 
        until after call to FIND_NEW_THREADS (which may change inferior_pid).
        Also some cosmetic fixups.
        * infrun.c: cosmetic fixups and casts to avoid warnings.
        * infcmd.c: cosmetic fixups, mainly long lines.
        
Tue Jan  5 11:55:57 1999  David Taylor  <taylor@texas.cygnus.com>

        * target.c (noprocess): terminate sentence with a period.
        * breakpoint.c (catch_command_1): ditto.

        * c-valprint.c (c_value_print): remove hack^2 from HP; it causes
        testsuite losses with no real gain.

        * inferior.h (START_INFERIOR_TRAPS_EXPECTED): restore, but only
        if tm-*.h hasn't overridden default value.

1999-01-04  Jason Molenda  (jsm@bugshack.cygnus.com)

        * configure.in: Fix whitespace indentation for --help.
        * configure: Regenerated.

1999-01-04  Manuel Bouyer <bouyer@antioche.lip6.fr>

        * main.c: Add --write command line option, document -w.
        * gdb.1: Document --write.

1999-01-04  Jason Molenda  (jsm@bugshack.cygnus.com)

        * configure.in: Require autoconf 2.12.1 or higher.
        * doc/configure.in: Ditto.
        * nlm/configure.in: Ditto.
        * rdi-share/configure.in: Ditto.
        * testsuite/configure.in: Ditto.
        * doc/Makefile.in: Don't hardcode $(SHELL).
        * nlm/Makefile.in: Ditto.
        * rdi-share/Makefile.in: Ditto.
        * testsuite/Makefile.in: Ditto.

Mon Jan  4 12:53:03 1999  Stan Shebs  <shebs@andros.cygnus.com>

        * remote-vx.c (init_vx_ops, init_vx_run_ops): Remove unneeded
        inits of new fields, including ref to bogus field.
        (vx_ops, vx_run_ops): Make static.

Mon Jan  4 15:05:29 1999  David Taylor  <taylor@texas.cygnus.com>

        * inferior.h (START_INFERIOR_TRAPS_EXPECTED): delete,
        already defined in tm.h.

        * inftarg.c: change <sys/unistd.h> to <unistd.h> and
        conditionalize its inclusion.
        * infttrace.c: ditto.
