        * tracepoint.c, tracepoint.h: new module, implements tracing,
        which is a new functionality somewhat like breakpoints except
        that a tracepoint stops the inferior only long enough to collect
        and cache selected buffers and memory locations, then allows 
        the inferior to continue; the cached trace data can then be 
        examined later.

        do the usual promotions. 
        * stabsread.c (define_symbol): Set the TYPE_FLAG_PROTOTYPED flag
        on functions' types when we can; all C++ functions should get it,
        and if the Sun-style prototype notation is in the stabs, we can
        notice that.

Fri Nov 21 12:20:16 1997  Ian Lance Taylor  <ian@cygnus.com>

        * config/i386/i386gnu.mh: remove rules for [i386]gnu-nat.o, now 
        in Makefile.in (as for other targets); add NATDEPFILE corelow.o to 
        satisfy symbol dependancy in solib.c (core_ops).
        * target.[ch] conditionalize Mach-specific signals so that they
        won't show up in non-Mach gdb's!
        * thread.c: change name of static function "thread_switch" to 
        "switch_to_thread", to avoid conflict with Mach global symbol; 
        move thread_cmd_list to global scope so targets can add their 
        own thread commands.
        * infrun.c: sig_print_info: allow for long signal names.
        * gnu-nat.[ch]: tidying up comments.
        * gnu-nat.c: remove calls to prune_threads and renumber_threads; 
        gnu_wait must not return -1 when inferior exits; 
        attach_to_child will modify inferior_pid in a way that allows
        fork_inferior to remain unchanged; remove extra arg from 
        startup_inferior; move Mach thread commands here from thread.c.

Mon Apr 28 18:21:20 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>

        (xcoff_relocate_core):  No longer adjust section addresses by VMA.
        * rs6000-tdep.c (find_toc_address):  Change type of tocbase
        to CORE_ADDR.
        * xcoffread.c (secnum_to_bfd_section):  New routine to get
        BFD section from CS section number.
        (scan_xcoff_symtab):  Make toc_offset section relative.

        * symtab.c (total_number_of_methods):  Avoid core dump if
        baseclass type is still undefined.

Fri Apr 18 17:25:10 1997  Stu Grossman  (grossman@critters.cygnus.com)

        * Makefile.in (SUBDIRS):  Add mswin so that make cleanup cleans up
        that directory.
        * defs.h utils.c (error warning):  Make message be const.
        * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr
        to hook.  Otherwise send it to fputs.
        * monitor.c monitor.h (monitor_get_dev_name):  New function.  Does
        the obvious.
        * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
        to _filtered forms to make output appear in GUIs.  Replace all
        uses of SERIAL_READCHAR with readchar, which has better error
        checking.
        * (e7000_parse_device):  Add prototype.
        (readchar):  Improve doc.  Handle random serial errors.
        (expect):  Disable notice_quit code.  It's busted.  Remove
        serial error handling (it's now handled in readchar).  Remove
        remote_debug echoing.  That's handled in readchar as well.
        (e7000_parse_device):  Remove serial_flag arg.  It's not
        necessary.
        (e7000_open):  Split into two pieces.  Second part is
        e7000_start_remote, and is error protected.  Now, when we connect
        to the target, we setup the initial frame and registers so that
        the user gets an immediate indication of where the target is.
        (gch):  Remove debug output.  That's handled by readchar.
        (e7000_read_inferior_memory):  Handle errors better.
        (_initialize_remote_e7000):  Get rid of `<xxx>' things from
        command names.  They show up when doing completion and confuse
        things horribly.
        * ser-e7kpc.c: Get rid of the DLL's since we can access the device
        directly from Win32s and Win95.  Get rid of debugify crud.
        * serial.c:  Remove debugify cruft.
        * (serial_logchar serial_log_command serial_write serial_readchar
        serial_send_break serial_close):  Merge common functionality into
        serial_logchar.  Clean up rest of routines.
        * sparclet-rom.c:  Disembowel.  Leave only download routine.
        Download routine now switches to remote target automatically.
        * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
        up MSVC/Win32 problem.
        * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
        or gdb_stderr.
        * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.
        * config/sparc/tm-sparclet.h:  Remove override for prompt.

Fri Apr 18 13:38:19 1997  Doug Evans  <dje@canuck.cygnus.com>

        * remote-sim.c (init_callbacks): Initialize poll_quit and magic
        fields of gdb_callback.
        (gdbsim_stop): Add gdbsim_stop to list of supported client
        operations.
        (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
        sim_wait where gdb is in a position to handle a long running
        function.
        (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
        SIGINT handler.
        (gdb_os_poll_quit): New function. Check for a quit pending on the
        console.

Thu Apr 17 14:30:04 1997  Per Bothner  <bothner@deneb.cygnus.com>

        * objfiles.c (allocate_objfile):  Allow NULL bfd argument.
        * defs.h (enum language):  Add language_java.
        * java-exp.y, java-lang.c, java-lang.h, java-valprint.c:  New files.
        * Makefile.in:  Update for new files.
        * symfile.c (deduce_language_from_filename):  Recognize .java.

Thu Apr 17 02:20:23 1997  Doug Evans  <dje@canuck.cygnus.com>

        * m32r-stub.c (stash_registers): Rewrite.
        (restore_registers): Renamed to restore_and_return.
        (cleanup_stash): New function.
        (process_exception): New function.
        (_catchException*): Rewrite.

        * remote-sim.c (gdbsim_load): Update call to sim_load.

        response to qOffsets.

Tue Apr 15 14:51:04 1997  Ian Lance Taylor  <ian@cygnus.com>

        * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
        (INSTALL_XFORM1): Remove.
        (install-only): Use $(program_transform_name) directly, rather
        than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
        (uninstall): Transform name.

Mon Apr 14 17:06:27 1997  Mark Alexander  <marka@cygnus.com>

        * remote-mips.c (mips_load): Ensure that PC gets updated
        after a load on LSI target.

Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>

        * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
        since gcc automatically includes it

Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>

        * procfs.c: Substantial (but incomplete) changes to support
        sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
        struct now has substructs like struct flt_ctl instead of
        just a fltset_t and has a ctl_fd, status_fd, as_fd, and
        map_fd instead of a single fd.  Non-sysv4.2mp procfs models
        still have the structs and multiple fds, but don't use the
        entire struct and the four fds all point to the same thing.
        We use PROCFS_USE_READ_WRITE to decide whether to talk to
        procfs with reads/writes or use ioctl instead.  We use
        HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
        multiple fds or not.  PROC_NAME_FMT is split out into
        CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, 
        STATUS_PROC_NAME_FMT.
        
        (procfs_notice_signals): now a necessary wrapper around
        (notice_signals): which are the new guts for noticing signals
        (open_proc_file): gets a new flag arg used in sysv4.2mp to
        determine whether or not to attempt to open the ctl_fd.
        (procfs_read_status): new local function, reads procfs status
        (procfs_write_pcwstop): new local function, writes a PCWSTOP
        (procfs_write_pckill): new local function, writes a PCKILL
        (unconditionally_kill_inferior): remove signo since we now
        just call procfs_write_pckill().
        (procfs_xfer_memory): call lseek with SEEK_SET rather than 0    
        (proc_iterate_over_mappings): the whole function is ifdefed
        on UNIXWARE to keep things readable.
        
        Expanded the syscall_table to include new potential sysv4.2mp
        members.  Note that all ifdefs of UNIXWARE should be eliminated
        if possible or renamed to describe what's being selected for a
        bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
        IRIX specific code now also checks it's not UNIXWARE.

        * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
        HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
        * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
        "/debug/%d" as PROC_NAME_FMT used to be

Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)

        * mn10300-tdep.c: Almost completely rewritten based on mn10200
        port.
        * config/mn10300/tm-mn10300.h: Likewise.

Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)

        * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
        remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
        lousy out-of-date clone of remote.c.

Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)

        * remote.c:  Fix problems realized while showering.
        * (hexnumlen):  Add prototype.  Use max, not min.
        * (remote_write_bytes remote_read_bytes):  Fix max packet size
        calculations to properly account for packet overhead.  Also handle
        (probably rare) case where remote_register_buf_size isn't set.

        * remote.c:  Fix doc for `C' and `S' commands to indicate full
        address.
        * (remote_ops extended_remote_ops remote_desc remote_write_size):
        Make static.
        * (remote_fetch_registers remote_write_bytes remote_read_bytes):
        Record size of response to fetch registers command, use this to
        limit size of memory read and write commands.
        * (push_remote_target):  New function to make it possible to have
        another target switch to the remote target.
        * target.h:  Add prototype for push_remote_target.
        * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
        for hosts which default to unsigned chars (such as SGI's).
        * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
        handled automatically in remote.c.

Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>

        * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(), 
        find_pc_sect_function(), find_pc_sect_partial_function(): new 
        functions for debugging overlays; pc without section is ambiguous.
        * breakpoint.[ch]: add section pointer to breakpoint struct;
        add section argument to check_duplicates(); check section as well
        as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
        breakpoint_thread_match(), bpstat_stop_status()];  
        add section argument to describe_other_breakpoints(); 
        use INIT_SAL() macro to zero-out new sal structures; 
        make resolve_sal_pc() fix up the sal's section as well as its pc; 
        match on section + pc in clear_command() and delete_breakpoint(); 
        account for overlay sections in insert_breakpoints(), 
        remove_breakpoint() and breakpoint_re_set_one();
        all this to support overlays where a PC is not unique.
        * exec.c: change xfer_memory() to handle overlay sections.
        * findvar.c: change read_var_value() to handle overlay sections.
        * frame.h: declaration for block_for_pc_sect() [blockframe.c].
        * infcmd.c: jump_command() warns against jumping into an overlay

        instead of VMA address, for overlay sections.
        Add numerous functions for finding a PC's section / overlay, 
        translating between VMA and LMA address ranges, determining if an
        overlay section is mapped, etc.  Add several user commands for
        overlay debugging.  Add support for a "generic" form of automatically
        reading overlay mapping info from the inferior (based on the default
        (simple) overlay manager which Cygnus provides as an example).
        * symtab.[ch]: add functions find_pc_sect_symtab(), 
        find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
        for lookup; modify lookup_symbol and decode_line_1() to use them;
