   3         * gdbtk-cmds.c (gdb_cmd): Do not run the timer when downloading --
   4         the ui_progress_hook that has been installed will actually
   5         update the gui for us.

  17
  18         * gdbtk-cmds.c (Gdbtk_Init): Link C variable gdb_context
  19         with tcl variable gdb_context_id.

  33
  34 Fri Aug 28 12:14:49 1998  Martin M. Hunt  <hunt@cygnus.com>
  35
  36         * gdbtk-cmds.c (gdb_loadfile): Open the file after doing
  37         the symtab lookup and calling symtab_to_filename(). This
  38         makes GDBtk work with the GDB "dir" command.
  39
  40 1998-08-18  Keith Seitz  <keiths@cygnus.com>
  41
  42         * gdbtk-hooks.c (gdbtk_add_hooks): Set selected_frame_level_changed_hook.

  59
  60         * Makefile.in (FOUNDRY_LIB_BASE): Added the Foundry SDK code that allows
  61         gdbtk to be linked with the Foundry libraries provided by a prebuilt/released
  62         binary version of Foundry.  The libraries and header files need to come from
  63         the installed location of Foundry rather than the devo subdirectories.
  64         * configure.in (ENABLE_IDE): Foundry SDK additions.  Added the "with-foundry-libs"
  65         configure option.
  66         * configure: Foundry SDK additions.  Regenerated from configure.in.

  68 end-sanitize-ide
  69 Thu Aug 13 15:09:59 1998  Drew Moseley  <dmoseley@cygnus.com>
  70
  71         * gdbtk.c (gdbtk_cleanup): added a scope-level around the contents
  72         of the #ifdef so that the variable declarations in there would not
  73         be illegal in a C compilation.
  74
  75 Mon Jul 27 13:07:16 1998  Martin M. Hunt  <hunt@cygnus.com>
  76
  77         * gdbtk.c (gdbtk_call_command): Removed because it is now
  78         in gdbtk-hooks.c
  79         (null_routine): Removed.
  80
  81         * gdbtk-hooks.c (tracepoint_notify): Fix sprintf to
  82         match number of arguments.
  83
  84         * gdbtk-cmds.c (gdb_loc): When calling gdb_loc with an
  85         argument, call find_pc_line() to get a complete
  86         symtab_and_line struct.
  87
  88 Fri Jul 24 14:25:43 1998  Keith Seitz  <keiths@cygnus.com>
  89
  90         * gdbtk-cmds.c (gdb_search): Add missing NULL to switches.
  91         Add missing flags to result_ptr.
  92         Pass along any errors caused by getting the list of files from
  93         tcl.
  94         Allocate correct amount of memory for the file list.
  95         Don't do any unecessary cleanups.
  96
  97 Fri Jul 24 01:08:37 1998  Martin M. Hunt  <hunt@cygnus.com>
  98
  99         * gdbtk-cmds.c (gdb_loadfile): When there are no
 100         linenumbers, use only one tab.
 101
 102 Sat Jul 18 12:28:39 1998  Martin M. Hunt  <hunt@cygnus.com>
 103
 104         * gdbtk.c (gdbtk_cleanup): Add call to tcl function
 105         gdbtk_cleanup. We need this so the GUI gets to clean
 106         up no matter how GDB exits.
 107
 108 Wed Jul  1 13:10:58 1998  Jim Ingham   <jingham@cygnus.com>
 109
 110         * Moved gdbtk_hooks.c & gdbtk_cmds.c to gdbtk-hooks.c &
 111         gdbtk-cmds.c to comply with the gdb conventions.  Changed the
 112         configure & makefile to reflect the change...
 113
 114 Wed Jul  1 11:07:21 1998  Jim Ingham   <jingham@cygnus.com>
 115
 116         * gdbtk.c: removed all the commands and hooks from this file so
 117         now it contains only the startup code.
 118         * gdbtk.c (gdbtk_init): Fixed a bug in the startup code on Windows
 119         that caused gdbtk not to find the share directory unless
 120         GDBTK_LIBRARY was set.
 121         * gdbtk_cmds.c: New file - this contains all the Tcl commands that
 122         gdb defines.  All the old commands were moved here, the
 123         string-based commands were converted to object commands, and the
 124         object-based commands were all converted to uniformly use the
 125         call_wrapper.  A new function, Gdbtk_Init was added to centralize
 126         initializing the gdb package.
 127         * gdbtk_hooks.c: New file - All the hooks were moved here, and a new
 128         function, gdbtk_add_hooks was added to centralize adding all these
 129         hook functions.  gdbtk_fputs was also modified to handle the new
 130         result_ptr structure.  See the comments in gdbtk.h for more
 131         details.
 132         * gdbtk.h: New file - this contains all the defines and globals
 133         shared by gdbtk.c, gdbtk_cmds.c & gdbtk_hooks.c
 134         * Makefile.in, configure.in & configure: mutatis mutandi for the
 135         new files.
 136
 137
 138 Mon Jun 29 11:49:17 1998  Keith Seitz  <keiths@cygnus.com>
 139
 140         * main.c (main): Don't include gdbtk test code if GDBTK is
 141         not defined by configure.
 142
 143         * configure.in: When enabling gdbtk, add "-DGDBTK" to ENABLE_CFLAGS.
 144
 145         * configure: Regenerate.
 146
 147 Fri Jun 26 13:56:07 1998  Keith Seitz  <keiths@cygnus.com>
 148
 149         * gdbtk.c: Change all references to static global "interp" to
 150         "gdbtk_interp" and export this global.
 151         (gdbtk_init): If gdbtk_source_filename is not NULL, source this file
 152         into the interpreter when it goes idle.
 153         Add new command "gdb_search".
 154         (gdb_search): New function which searches the symbol table.
 155         (gdbtk_test): New function called by main when the --tclcommand
 156         option is used.
 157
 158         * main.c (main): Add a new option "--tclcommand" which is used
 159         by the testsuite to source a file into the interpreter when it
 160         goes idle.
 161
 162 Wed Jun 17 19:12:23 1998  Jeff Holcomb  <jeffh@cygnus.com>
 163
 164         * Makefile.in (install-only): Install tracing help files.
 165
 166 Mon Jun 15 13:18:21 1998  Jim Ingham <jingham@cygnus.com>
 167
 168         * gdbtk.c (gdbtk_init): Add elements to the auto_path AS LIST
 169         ELEMENTS.  This allows gdbtk to work when installed in a directory
 170         which has a space in the path.  D. Moseley pointed out the bug.
 171
 172
 173 Tue Jun  9 14:10:46 1998  Keith Seitz  <keiths@cygnus.com>
 174
 175         * gdbtk.c (gdb_get_vars_command): Return static variables and
 176         variables stored in registers.
 177

 187
 188         * gdbtk.c (gdbtk_init): Initialize tkTable.
 189
 190 Thu Jun  4 10:15:03 1998  Elena Zannoni  <ezannoni@kwikemart.cygnus.com>
 191
 192         * gdbtk.c: merged:
 193
 194         - Elena Zannoni  <ezannoni@kwikemart.cygnus.com>
 195         (call_obj_wrapper): in case of error, copy the
 196         error message from the result to the error_string.
 197         (gdbtk_fputs): add comments.
 198         (gdb_actions_command): call validate_actionline when installing the
 199         tracepoint, to do the syntax checking of the actions for us.
 200         - Elena Zannoni  <ezannoni@kwikemart.cygnus.com>
 201         (gdb_get_trace_frame_num): new function to get the
 202         trace frame number from gdb.
 203         (gdbtk_init): added new command gdb_get_trace_frame_num.

 205         (struct wrapped_call_objs): Change the `func' member to
 206         be a Tcl_ObjCmdProc, not an Tcl_CmdProc, since it accepts a vector
 207         of objects as arguments.  Change the object vector to be const,
 208         since that's what all the users of this structure seem to expect.
 209         (call_obj_wrapper): Cast clientData properly before storing it in
 210         the wrapped_args structure.
 211
 212 Thu May 28 17:19:14 1998  Keith Seitz  <keiths@cygnus.com>
 213
 214         * gdbtk.c (_initialize_gdbtk): Get rid of the console. Patch from

 218
 219         * configure: Regenerated
 220
 221 Sun May 24 14:00:24 1998  Keith Seitz  <keiths@cygnus.com>
 222
 223         * ser-unix.c (wait_for): Do not reset timeout_remaining for cygwin32 so that
 224         we can use this member to track real timeouts.
 225         (hardwire_readchar): Modify for cygwin32 so that we only ever use a real
 226         system timeout of one second. Track the "real" timeout as a series of these
 227         one second timeouts.
 228         Call ui_loop_hook to keep the gui alive.
 229
 230         * top.c: Define new hook for cygwin32, "ui_loop_hook".
 231
 232         * gdbtk.c (gdbtk_init): Add ui_loop_hook for CygWin32 to work around
 233         update problems.
 234
 235 Thu May 21 13:56:24 1998  Elena Zannoni  <ezannoni@kwikemart.cygnus.com>
 236
 237         * gdbtk.c: reinserted the changes that were accidentally deleted:

 239         cygwin-specific call (cosmetic change).
 240         (gdbtk_ignorable_warning): removed va_list parameter,
 241         which was unused.
 242         (_initialize_gdbtk): add cygwin32 specific code to
 243         allow `gdb -nw' to work when specified specified from a windows
 244         console-mode command line.
 245
 246 Wed May 13 11:12:58 1998  James Ingham  <jingham@leda.cygnus.com>
 247
 248         * gdbtk.c: Fixed a goof in the definition of the gdb_get_args &
 249         gdb_get_locals Tcl commands.  Moved the previous ChangeLog entry
 250         from ChangeLog to ChangeLog-gdbtk (here)...
 251
 252 Tue May 12 13:29:20 1998  Jeff Holcomb  <jeffh@cygnus.com>
 253
 254         * Makefile.in (install-only): Add images/icons.txt and
 255         images2/icons.txt to files that need to be installed.
 256
 257 Tue May 12 12:03:16 1998  James Ingham  <jingham@leda.cygnus.com>
 258
 259         * gdbtk.c: Add an object call wrapper for the new Tcl_Obj based
 260         commands.  This way the obj commands will also go through
 261         catch_errors.  This is just a bandaid while I rewrite the
 262         string-based commands to use the object format.
 263
 264 Tue May  5 09:30:25 1998  Christopher Faylor <cgf@cygnus.com>

 290
 291         * gdbtk.c (gdb_loadfile): Change fstat() call to stat().
 292         Needed because you can't convert a FILE* to an fd.
 293

 300         (gdbtk_ignorable_warning) new function to pass a warning
 301         to the gui. Used only for the src. vs. exec check.
 302         (gdbtk_init) added warning_hook
 303         added include <sys/stat.h>
 304

1393 Tue Apr 11 11:07:12 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
1394
1395         * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, but
1396         F_SETOWN is, use that.
1397
1398 Thu Apr  6 17:00:46 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
1399
1400         * Makefile.in (X11_INCLUDES): Define as empty.
1401         (X11_CFLAGS): Define as including $(X11_INCLUDES).
1402         (X11_LIB_SWITCHES): Define as empty.
1403         (X11_LIBS): Define as -lX11.
1404
1405         * configure.in (enable_gdbtk): If gdbtk, support the --x-includes
1406         and --x-libraries switches, setting the X11_INCLUDES and
1407         X11_LIB_SWITCHES respectively.  Instead of using a hardcoded -lX11
1408         in ENABLE_CLIBS, use the X11_LIB_SWITCHES and X11_LIBS variables.
1409
1410         * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, don't use
1411         it.  This means that the stop button doesn't work, but is better
1412         than nothing.
1413
1414 Wed Mar 29 17:09:29 1995  Stu Grossman  (grossman@cygnus.com)
1415
1416         * Makefile.in (gdbtk.o):  Use X11_CFLAGS to provide alternate
1417         locations (per-host) for X11 include files.
1418         * config/pa/hppahpux.mh (XM_CLIBS):  Add -L/usr/lib/X11R5 to force
1419         the use of R5 libs.
1420         (X11_CFLAGS):  Add this to indicate the locs
1421         of the R5 include files.
1422
1423 Wed Mar  8 16:12:21 1995  Stu Grossman  (grossman@cygnus.com)
1424
1425         * gdbtk.c (gdb_get_breakpoint_info):  Return error if breakpoint
1426         type is not bp_breakpoint.
1427
1428 Tue Feb 14 17:16:41 1995  Stu Grossman  (grossman@cygnus.com)
1429
1430         * gdbtk.c: Ditto.
1431         * gdbtk.c: General cleanups, get rid of unused variables.  Redo
1432         handling of stdout/stderr to just return output as the result of
1433         the tcl command that caused the output.  Cleanup -Wall stuff.
1434         * (breakpoint_notify):  Now returns just action and breakpoint
1435         number.
1436         * (gdb_get_breakpoint_list):  New routine.  Does the obvious.
1437         * (gdb_get_breakpoint_info):  Mostly derived from the old
1438         breakpoint_notify, but returns lots more info.
1439         * (dsprintf_append_element):  Helper routine, works like printf,
1440         but appends a tcl element onto the specified DString.  Good for
1441         building up lists as return values.
1442         * (gdbtk_enable/disable_breakpoint):  Go away.  Replaced with
1443         gdbtk_modify_breakpoint.
1444         * (*many routines*):  Use new result protocol.
1445         * (call_wrapper):  Make sure that recursive calls don't trash results.
1446         * gdbtk.tcl:  New windows, autocmd, and breakpoints.
1447         * (gdbtk_tcl_fputs):  Don't use $current_output_win redirection
1448         anymore.  It's not needed (in fact, this routine may not be needed
1449         anymore).
1450         * (gdbtk_tcl_breakpoint):  Change to reflect new breakpoint
1451         notification protocol.
1452         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Straighten out buttons, remove
1453         catches.
1454         * (interactive_cmd):  Use this wrapper around button invocations
1455         of many commands.  This will catch errors and put the results into
1456         the command window.  It also updates all the other windows.
1457         * Also, change reliefs of most things to sunken.  This actually
1458         looks better.
1459         * (create_file_win):  Fix margin binding to allow breakpoints to
1460         work again.
1461         * (create_asm_win):  Use return value of gdb_disassemble instead
1462         of implicit I/O to the command window.
1463         * (create_command_window):  Use new result protocol to get output
1464         from commands.
1465
1466 Sun Feb  5 20:32:44 1995  Jim Kingdon  (kingdon@lioth.cygnus.com)
1467
1468         * gdbtk.c (gdb_disassemble): Deference pointer to function before
1469         calling it (pre-ANSI compilers generally require this).
1470
1471 Fri Feb  3 11:19:20 1995  Stu Grossman  (grossman@cygnus.com)
1472
1473         * gdbtk.c (gdb_disassemble): Get rid of
1474         dis_asm_read_memory_hook.  We can now call the disassemblers
1475         directly and have no need for this hook anymore.
1476
1477 Mon Jan 30 17:34:24 1995  Stu Grossman  (grossman@cygnus.com)
1478
1479         * gdbtk.tcl (create_file_win):  Disable old popup menu for source
1480         window.
1481
1482 Wed Jan 25 18:23:46 1995  Stu Grossman  (grossman@cygnus.com)
1483
1484         * gdbtk.c (gdbtk_init):  Prevent segfault when gdbtk.tcl can't be
1485         found.
1486         * gdbtk.tcl:  Initialize expr_update_list() to prevent errors when
1487         popping up expression window for the first time.
1488
1489 Tue Jan 24 12:10:28 1995  Stu Grossman  (grossman@cygnus.com)
1490
1491         * gdbtk.tcl (create_registers_window):  Work around a radiobutton
1492         widget bug to make Options|Natural button work.
1493
1494         * gdbtk.c (gdb_disassemble):  Fix problem with source+assembly and
1495         g++ caused by out-of-order pc's.
1496         * gdbtk.tcl (files_command):  Remove duplicate file names.  Also,
1497         add scrollbar.
1498
1499 Mon Jan 23 17:21:09 1995  Stu Grossman  (grossman@cygnus.com)
1500
1501         * gdbtk.tcl:  Take .gdbtkinit if it exists.  Makes gdbtk match the
1502         doc!
1503
1504 Thu Jan 12 15:02:40 1995  Stu Grossman  (grossman@cygnus.com)
1505
1506         * gdbtk.c, gdbtk.tcl:  Update/add copyright.
1507         * gdbtk.tcl (build_framework):  Several fixes for filespec widget,
1508         including dismiss button, and better error handling.
1509         * (create_command_win):  Bind button 2 to retrieve selection.
1510
1511 Wed Jan 11 17:06:55 1995  Stu Grossman  (grossman@cygnus.com)
1512
1513         * gdbtk.tcl:  Add button to control mixed source disassembly.
1514         Use text widgets in expr window.  The give me more control over
1515         layout.
1516         Add auto-updating of exprs in expression window.
1517         Handle expressions out of scope a bit better.
1518         Make selected window pop up to the top when invoked via the
1519         menubar.
1520         Make copyright message have raised relief.
1521
1522         * gdbtk.c (gdbtk_init):  Improve handling for errors in gdbtk.tcl
1523         during startup.
1524
1525 Thu Jan  5 17:38:29 1995  Stu Grossman  (grossman@cygnus.com)
1526
1527         * gdbtk.c (finish_saving_output):  Don't do anything if not saving
1528         output.
1529         * (breakpoint_notify):  Don't send null filename to tcl.
1530         * (gdb_eval):  New tcl command to eval an expression.
1531         * (gdb_disassemble):  New tcl command to do disassembly.  This
1532         allows tcl code to choose between exec file and target memeory,
1533         and can also do mixed source and assembly.
1534         * (gdbtk_init):  Move reading of gdbtk.tcl to the end to make sure
1535         that more of the environment is set up.  Also, create link between
1536         gdb and tcl vars disassemble{-_}from{-_}exec.
1537
1538         * gdbtk.tcl:  New expression window support.
1539         * Make assembly window be 80 columns wide.

1546
1547         * Pop up a copyright window on startup.
1548
1549 Wed Jan  4 19:49:10 1995  Stan Shebs  <shebs@andros.cygnus.com>
1550
1551         * gdbtk.tcl (build_framework): Add standard commands menu, more
1552         windows to standard windows menu.
1553         (not_implemented_yet): Clarify message.
1554
1555 Fri Dec 30 15:49:00 1994  Stan Shebs  <shebs@andros.cygnus.com>
1556
1557         * gdbtk.tcl (FSBox): New proc, File Selection Box code from exmh.
1558         (not_implemented_yet): New proc.
1559         (build_framework): Add various file commands to file menu.
1560
1561 Fri Dec 23 16:18:50 1994  Stu Grossman  (grossman@cygnus.com)
1562
1563         * gdbtk.c (gdbtk_wait gdbtk_init):  Portability improvements for
1564         SIGIO handling.
1565
1566 Mon Dec 19 09:55:47 1994  Stu Grossman  (grossman@cygnus.com)
1567
1568         * gdbtk.tcl (update_assembly):  Force update to make sure that pc
1569         is visible when creating new assembly windows.
1570
1571 Sun Dec 18 23:31:20 1994  Stu Grossman  (grossman@cygnus.com)
1572
1573         * gdbtk.c (gdbtk_wait gdbtk_init):  Use different method of
1574         enabling I/O interrupts for SVR4 (streams).
1575         * (start_saving_output save_output get_saved_output
1576         finish_saving_output flush_holdbuf gdbtk_flush gdbtk_fputs
1577         gdbtk_init):
1578         Totally revamp to use TCLs dynamic string functions.  Also, quote
1579         all data passed back to TCL to prevent errors with unmatched
1580         braces, odd characters, etc...  This fixes several wierd problems
1581         with outputting strings containing unmatched braces.
1582         * (breakpoint_notify gdb_loc):  Use long hex format to output
1583         addresses of breakpoints and PCs.  This fixes some Alpha problems.
1584         * (breakpoint_notify):  Add stream arg to call to gdbtk_fputs.
1585         * (gdb_listfiles):  Also, go through the symtabs when looking for
1586         files.  This makes xcoff work (sort of), but probably breaks
1587         something else.
1588         * (gdb_stop):  Return TCL_OK instead of nothing.  This fixes odd
1589         TCL errors when hitting stop button.
1590         * (tk_command):  Don't pass interp->result on to Tcl_{Var}Eval, as
1591         that will trash the result.  strdup the result instead and pass
1592         that on.  Improve error handling as well.
1593
1594         * gdbtk.tcl (gdbtk_tcl_flush):  Use global def of
1595         current_output_win.  Makes flushing actually work!
1596         * (asm_win_name create_asm_win update_assembly):  Bunch of fixes
1597         to make assembly windows stop flashing when loading a new file.
1598         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Use catch to prevent gdb_cmd
1599         errors from losing control.
1600         * (create_source_window):  Add source file selection to View menu.
1601         * (create_command_window (<Key-Return> binding):  Quote text fed
1602         into gdb_cmd to prevent eval errors.

1605
1606         * gdbtk.c: Improve mechanism for capturing output values.
1607         (full_filename): Remove.
1608         (gdb_cmd call_wrapper gdbtk_init): Protect all calls from tcl land
1609         with call_wrapper.  This prevents longjmps (usually via error())
1610         from jumping out of tcl/tk and leaving things in an indeterminate
1611         state.
1612         (gdbtk_fputs): Differentiate stdout from stderr when passing text
1613         into tcl land.
1614         * gdbtk.tcl: New view option to disable line numbers.  Put catch
1615         around most uses of gdb_cmd.  Add update button to reg config
1616         window.  Stop doing immediate updates when selecting registers.
1617         Change register view values into checkbuttons.
1618
1619 Mon Dec 12 16:59:29 1994  Stu Grossman  (grossman@cygnus.com)
1620
1621         * gdbtk.tcl (reg_config_menu create_registers_window
1622         recompute_reg_display_list):  Use array instead of individual vars
1623         for register display list.
1624         * (recompute_reg_display_list update_registers):  Fix bug with not
1625         displaying all registers.
1626
1627 Mon Dec 12 12:22:21 1994  Stu Grossman  (grossman@cygnus.com)
1628
1629         * gdbtk.c:  New tcl commands:  gdb_fetch_registers,
1630         gdb_changed_register_list, and gdb_regnames.
1631         * gdbtk.tcl:  Use monochrome color model for now.
1632         * (delete_breakpoint_tag create_file_win):  Add breakdot support.
1633         * (create_file_win create_asm_win update_listing build_framework
1634         create_source_window create_command_window):  Re-org window
1635         creation to give all windows consistent look and feel.
1636         * (update_listing update_asm):  Change pc pointer to '->'.
1637         * (registers_command reg_config_menu create_registers_window
1638         populate_reg_window update_registers):  Revamp register window.
1639         Allow selection of registers to be displayed.  Highlight changed
1640         registers.

1645
1646         * gdbtk.tcl (build_framework):  Add "Report bug" to help menu.
1647

1665
1666 Tue Nov  1 16:41:12 1994  Stu Grossman  (grossman@cygnus.com)
1667
1668         * Makefile.in:  Use $(objdir)/tcl and $(objdir)/tk if they are
1669         available.
1670         * configure.in (ENABLE_CLIBS):  Use $(TCL) and $(TK) instead of
1671         -ltcl and -ltk.
1672         * gdbtk.c:  Get rid of lots of unnecessary #includes.
1673         * (gdbtk_init):  Use ConnectionNumber macro instead of referencing

1687         waits.
1688         * (gdbtk_call_command):  Wrapper around command processing to
1689         alert GUI of target state changes.
1690         * (gdbtk_init):  Get the fd of X server for doing async
1691         notification of X events (via x_event).  Setup new hooks.
1692         * gdbtk.tcl:  Add scrollbars to assembly and command windows.
1693         * Change window foreground & background colors.

1699         to just set or clear breakpoints when in the margin tag.
1700         * Change shape of register window to be more vertical to better
1701         reflect its contents.
1702         * Add stop button.
1703         * Cleanup some code around command window bindings.

1715         elegantly.  Also, create special window to display file open
1716         failure message.  Move opening of file prior to creation of text
1717         widget.
1718         * (create_asm_win):  Add PC as argument.  We now base disassembly
1719         on PC instead of function name, since function names can be
1720         ambiguous (usually seen with shared libs).  Also, use catch to
1721         simplify code where we don't care about failures.

1724
1725         * gdbtk.tcl:  Add ref counts to breakpoint tags.
1726         * Put quotes around function name in disassemble command to better
1727         handle assembler names containing `.'.
1728         * Make pclist element 0 be filler to avoid off-by-one problem with
1729         line numbers.
1730         * Set names of top-level windows.
1731         * Add register display window.
1732         * Add PC to label of assembly window.

1735
1736         * gdbtk.c (gdbtk_flush gdbtk_fputs):  Buffer up output to make
1737         disassembly more efficient.
1738         * (breakpoint_notify):  Include pc in gdbtk_tcl_breakpoint
1739         callback.
1740         * (gdb_loc):  Include pc in return value.  Also, return function
1741         name if arg was specified.
1742         * (gdb_cmd_stub):  Call gdb_flush to drain internal GDB buffers
1743         after command completes.
1744         * (gdbtk_init):  Improve error handling.
1745
1746         * gdbtk.tcl:  Add lots of comments.  Clean up code.
1747         * (gdbtk_tcl_fputs):  Make output window redirectable.
1748         * Add assembly window, and breapoint support.
1749         * Make button 1 in margin toggle breakpoints.
1750         * Use stippling to indicate breakpoint disabling.

1753
1754         * configure.in: Don't symlink to gdbtk.tcl if it's already there.

1758         Support for TK GUI.
1759         * Makefile.in:  Add rule for gdbtk.o.
1760         * configure.in:  Add support for --enable-gdbtk.
1761         * gdbtk.c:  New file.  Contains support routines for TK interface.
1762         * gdbtk.tcl:  New file.  Implements GUI policy.
