  31
  32         * gdbtk-cmds.c (gdb_cmd): Do not run the timer when downloading --
  33         the ui_progress_hook that has been installed will actually
  34         update the gui for us.

  64
  65         * gdbtk-cmds.c (gdb_loadfile): Open the file after doing
  66         the symtab lookup and calling symtab_to_filename(). This
  67         makes GDBtk work with the GDB "dir" command.
  68

  88
  89         * Makefile.in (FOUNDRY_LIB_BASE): Added the Foundry SDK code that allows
  90         gdbtk to be linked with the Foundry libraries provided by a prebuilt/released
  91         binary version of Foundry.  The libraries and header files need to come from
  92         the installed location of Foundry rather than the devo subdirectories.
  93         * configure.in (ENABLE_IDE): Foundry SDK additions.  Added the "with-foundry-libs"
  94         configure option.
  95         * configure: Foundry SDK additions.  Regenerated from configure.in.

  99
 100         * gdbtk.c (gdbtk_cleanup): added a scope-level around the contents
 101         of the #ifdef so that the variable declarations in there would not
 102         be illegal in a C compilation.
 103
 104 Mon Jul 27 13:07:16 1998  Martin M. Hunt  <hunt@cygnus.com>
 105
 106         * gdbtk.c (gdbtk_call_command): Removed because it is now
 107         in gdbtk-hooks.c
 108         (null_routine): Removed.
 109
 110         * gdbtk-hooks.c (tracepoint_notify): Fix sprintf to
 111         match number of arguments.
 112
 113         * gdbtk-cmds.c (gdb_loc): When calling gdb_loc with an
 114         argument, call find_pc_line() to get a complete
 115         symtab_and_line struct.
 116
 117 Fri Jul 24 14:25:43 1998  Keith Seitz  <keiths@cygnus.com>

 120         Add missing flags to result_ptr.
 121         Pass along any errors caused by getting the list of files from
 122         tcl.
 123         Allocate correct amount of memory for the file list.
 124         Don't do any unecessary cleanups.
 125
 126 Fri Jul 24 01:08:37 1998  Martin M. Hunt  <hunt@cygnus.com>
 127
 128         * gdbtk-cmds.c (gdb_loadfile): When there are no
 129         linenumbers, use only one tab.
 130
 131 Sat Jul 18 12:28:39 1998  Martin M. Hunt  <hunt@cygnus.com>
 132
 133         * gdbtk.c (gdbtk_cleanup): Add call to tcl function
 134         gdbtk_cleanup. We need this so the GUI gets to clean
 135         up no matter how GDB exits.
 136
 137 Wed Jul  1 13:10:58 1998  Jim Ingham   <jingham@cygnus.com>
 138
 139         * Moved gdbtk_hooks.c & gdbtk_cmds.c to gdbtk-hooks.c &
 140         gdbtk-cmds.c to comply with the gdb conventions.  Changed the

 143 Wed Jul  1 11:07:21 1998  Jim Ingham   <jingham@cygnus.com>
 144
 145         * gdbtk.c: removed all the commands and hooks from this file so
 146         now it contains only the startup code.
 147         * gdbtk.c (gdbtk_init): Fixed a bug in the startup code on Windows
 148         that caused gdbtk not to find the share directory unless
 149         GDBTK_LIBRARY was set.
 150         * gdbtk_cmds.c: New file - this contains all the Tcl commands that
 151         gdb defines.  All the old commands were moved here, the
 152         string-based commands were converted to object commands, and the
 153         object-based commands were all converted to uniformly use the
 154         call_wrapper.  A new function, Gdbtk_Init was added to centralize
 155         initializing the gdb package.
 156         * gdbtk_hooks.c: New file - All the hooks were moved here, and a new
 157         function, gdbtk_add_hooks was added to centralize adding all these
 158         hook functions.  gdbtk_fputs was also modified to handle the new
 159         result_ptr structure.  See the comments in gdbtk.h for more
 160         details.
 161         * gdbtk.h: New file - this contains all the defines and globals
 162         shared by gdbtk.c, gdbtk_cmds.c & gdbtk_hooks.c
 163         * Makefile.in, configure.in & configure: mutatis mutandi for the
 164         new files.
 165

 167 Mon Jun 29 11:49:17 1998  Keith Seitz  <keiths@cygnus.com>
 168
 169         * main.c (main): Don't include gdbtk test code if GDBTK is
 170         not defined by configure.
 171
 172         * configure.in: When enabling gdbtk, add "-DGDBTK" to ENABLE_CFLAGS.
 173
 174         * configure: Regenerate.

 176 Fri Jun 26 13:56:07 1998  Keith Seitz  <keiths@cygnus.com>
 177
 178         * gdbtk.c: Change all references to static global "interp" to
 179         "gdbtk_interp" and export this global.
 180         (gdbtk_init): If gdbtk_source_filename is not NULL, source this file
 181         into the interpreter when it goes idle.
 182         Add new command "gdb_search".
 183         (gdb_search): New function which searches the symbol table.
 184         (gdbtk_test): New function called by main when the --tclcommand
 185         option is used.
 186
 187         * main.c (main): Add a new option "--tclcommand" which is used
 188         by the testsuite to source a file into the interpreter when it
 189         goes idle.
 190
 191 Wed Jun 17 19:12:23 1998  Jeff Holcomb  <jeffh@cygnus.com>
 192
 193         * Makefile.in (install-only): Install tracing help files.
 194
 195 Mon Jun 15 13:18:21 1998  Jim Ingham <jingham@cygnus.com>
 196
 197         * gdbtk.c (gdbtk_init): Add elements to the auto_path AS LIST
 198         ELEMENTS.  This allows gdbtk to work when installed in a directory
 199         which has a space in the path.  D. Moseley pointed out the bug.
 200
 201
 202 Tue Jun  9 14:10:46 1998  Keith Seitz  <keiths@cygnus.com>

 224         (call_obj_wrapper): in case of error, copy the
 225         error message from the result to the error_string.
 226         (gdbtk_fputs): add comments.
 227         (gdb_actions_command): call validate_actionline when installing the
 228         tracepoint, to do the syntax checking of the actions for us.
 229         - Elena Zannoni  <ezannoni@kwikemart.cygnus.com>
 230         (gdb_get_trace_frame_num): new function to get the
 231         trace frame number from gdb.

 234         (struct wrapped_call_objs): Change the `func' member to
 235         be a Tcl_ObjCmdProc, not an Tcl_CmdProc, since it accepts a vector
 236         of objects as arguments.  Change the object vector to be const,
 237         since that's what all the users of this structure seem to expect.
 238         (call_obj_wrapper): Cast clientData properly before storing it in
 239         the wrapped_args structure.
 240

 248         * configure: Regenerated
 249

 251
 252         * ser-unix.c (wait_for): Do not reset timeout_remaining for cygwin32 so that
 253         we can use this member to track real timeouts.
 254         (hardwire_readchar): Modify for cygwin32 so that we only ever use a real
 255         system timeout of one second. Track the "real" timeout as a series of these
 256         one second timeouts.
 257         Call ui_loop_hook to keep the gui alive.
 258
 259         * top.c: Define new hook for cygwin32, "ui_loop_hook".
 260
 261         * gdbtk.c (gdbtk_init): Add ui_loop_hook for CygWin32 to work around
 262         update problems.
 263
 264 Thu May 21 13:56:24 1998  Elena Zannoni  <ezannoni@kwikemart.cygnus.com>

 268         cygwin-specific call (cosmetic change).
 269         (gdbtk_ignorable_warning): removed va_list parameter,
 270         which was unused.
 271         (_initialize_gdbtk): add cygwin32 specific code to
 272         allow `gdb -nw' to work when specified specified from a windows
 273         console-mode command line.
 274
 275 Wed May 13 11:12:58 1998  James Ingham  <jingham@leda.cygnus.com>
 276
 277         * gdbtk.c: Fixed a goof in the definition of the gdb_get_args &
 278         gdb_get_locals Tcl commands.  Moved the previous ChangeLog entry
 279         from ChangeLog to ChangeLog-gdbtk (here)...
 280
 281 Tue May 12 13:29:20 1998  Jeff Holcomb  <jeffh@cygnus.com>
 282
 283         * Makefile.in (install-only): Add images/icons.txt and
 284         images2/icons.txt to files that need to be installed.
 285
 286 Tue May 12 12:03:16 1998  James Ingham  <jingham@leda.cygnus.com>
 287
 288         * gdbtk.c: Add an object call wrapper for the new Tcl_Obj based
 289         commands.  This way the obj commands will also go through
 290         catch_errors.  This is just a bandaid while I rewrite the
 291         string-based commands to use the object format.
 292
 293 Tue May  5 09:30:25 1998  Christopher Faylor <cgf@cygnus.com>

 319
 320         * gdbtk.c (gdb_loadfile): Change fstat() call to stat().

 329         (gdbtk_ignorable_warning) new function to pass a warning
 330         to the gui. Used only for the src. vs. exec check.
 331         (gdbtk_init) added warning_hook
 332         added include <sys/stat.h>
 333

1395            Up/Down - Scroll up/down one line at a time
1396            Next/Prior - Scroll up/down one page at a time
1397            Home/End - Warp to current pc/end of file

1402 Fri May 19 06:15:40 1995  Jim Kingdon  <kingdon@deneb.cygnus.com>
1403
1404         * gdbtk.c: Conditionalize use of stdarg rather than varargs on
1405         ANSI_PROTOTYPES not __STDC__; it must match the definition of
1406         PARAMS.
1407

1409
1410         * gdbtk.c (gdbtk_query): Use stdarg.h macros when compiling with
1411         an ANSI compiler.
1412
1413 Sat Apr 15 13:52:24 1995  Stan Shebs  <shebs@andros.cygnus.com>

1419
1420         * README.GDBTK:  New file.  Contains the obvious.
1421
1422 Tue Apr 11 11:07:12 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
1423
1424         * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, but
1425         F_SETOWN is, use that.
1426
1427 Thu Apr  6 17:00:46 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
1428
1429         * Makefile.in (X11_INCLUDES): Define as empty.
1430         (X11_CFLAGS): Define as including $(X11_INCLUDES).
1431         (X11_LIB_SWITCHES): Define as empty.
1432         (X11_LIBS): Define as -lX11.
1433
1434         * configure.in (enable_gdbtk): If gdbtk, support the --x-includes
1435         and --x-libraries switches, setting the X11_INCLUDES and
1436         X11_LIB_SWITCHES respectively.  Instead of using a hardcoded -lX11
1437         in ENABLE_CLIBS, use the X11_LIB_SWITCHES and X11_LIBS variables.
1438
1439         * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, don't use
1440         it.  This means that the stop button doesn't work, but is better
1441         than nothing.
1442
1443 Wed Mar 29 17:09:29 1995  Stu Grossman  (grossman@cygnus.com)
1444
1445         * Makefile.in (gdbtk.o):  Use X11_CFLAGS to provide alternate
1446         locations (per-host) for X11 include files.
1447         * config/pa/hppahpux.mh (XM_CLIBS):  Add -L/usr/lib/X11R5 to force
1448         the use of R5 libs.
1449         (X11_CFLAGS):  Add this to indicate the locs
1450         of the R5 include files.
1451
1452 Wed Mar  8 16:12:21 1995  Stu Grossman  (grossman@cygnus.com)
1453
1454         * gdbtk.c (gdb_get_breakpoint_info):  Return error if breakpoint
1455         type is not bp_breakpoint.
1456
1457 Tue Feb 14 17:16:41 1995  Stu Grossman  (grossman@cygnus.com)
1458
1459         * gdbtk.c: Ditto.
1460         * gdbtk.c: General cleanups, get rid of unused variables.  Redo
1461         handling of stdout/stderr to just return output as the result of
1462         the tcl command that caused the output.  Cleanup -Wall stuff.
1463         * (breakpoint_notify):  Now returns just action and breakpoint
1464         number.
1465         * (gdb_get_breakpoint_list):  New routine.  Does the obvious.
1466         * (gdb_get_breakpoint_info):  Mostly derived from the old
1467         breakpoint_notify, but returns lots more info.
1468         * (dsprintf_append_element):  Helper routine, works like printf,
1469         but appends a tcl element onto the specified DString.  Good for
1470         building up lists as return values.
1471         * (gdbtk_enable/disable_breakpoint):  Go away.  Replaced with
1472         gdbtk_modify_breakpoint.
1473         * (*many routines*):  Use new result protocol.
1474         * (call_wrapper):  Make sure that recursive calls don't trash results.
1475         * gdbtk.tcl:  New windows, autocmd, and breakpoints.
1476         * (gdbtk_tcl_fputs):  Don't use $current_output_win redirection
1477         anymore.  It's not needed (in fact, this routine may not be needed
1478         anymore).
1479         * (gdbtk_tcl_breakpoint):  Change to reflect new breakpoint
1480         notification protocol.
1481         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Straighten out buttons, remove
1482         catches.
1483         * (interactive_cmd):  Use this wrapper around button invocations
1484         of many commands.  This will catch errors and put the results into
1485         the command window.  It also updates all the other windows.
1486         * Also, change reliefs of most things to sunken.  This actually
1487         looks better.
1488         * (create_file_win):  Fix margin binding to allow breakpoints to
1489         work again.
1490         * (create_asm_win):  Use return value of gdb_disassemble instead
1491         of implicit I/O to the command window.
1492         * (create_command_window):  Use new result protocol to get output
1493         from commands.
1494
1495 Sun Feb  5 20:32:44 1995  Jim Kingdon  (kingdon@lioth.cygnus.com)
1496
1497         * gdbtk.c (gdb_disassemble): Deference pointer to function before
1498         calling it (pre-ANSI compilers generally require this).
1499
1500 Fri Feb  3 11:19:20 1995  Stu Grossman  (grossman@cygnus.com)
1501
1502         * gdbtk.c (gdb_disassemble): Get rid of
1503         dis_asm_read_memory_hook.  We can now call the disassemblers
1504         directly and have no need for this hook anymore.
1505
1506 Mon Jan 30 17:34:24 1995  Stu Grossman  (grossman@cygnus.com)
1507
1508         * gdbtk.tcl (create_file_win):  Disable old popup menu for source
1509         window.

1511 Wed Jan 25 18:23:46 1995  Stu Grossman  (grossman@cygnus.com)
1512
1513         * gdbtk.c (gdbtk_init):  Prevent segfault when gdbtk.tcl can't be
1514         found.
1515         * gdbtk.tcl:  Initialize expr_update_list() to prevent errors when
1516         popping up expression window for the first time.
1517
1518 Tue Jan 24 12:10:28 1995  Stu Grossman  (grossman@cygnus.com)
1519
1520         * gdbtk.tcl (create_registers_window):  Work around a radiobutton
1521         widget bug to make Options|Natural button work.
1522
1523         * gdbtk.c (gdb_disassemble):  Fix problem with source+assembly and
1524         g++ caused by out-of-order pc's.
1525         * gdbtk.tcl (files_command):  Remove duplicate file names.  Also,
1526         add scrollbar.
1527
1528 Mon Jan 23 17:21:09 1995  Stu Grossman  (grossman@cygnus.com)
1529
1530         * gdbtk.tcl:  Take .gdbtkinit if it exists.  Makes gdbtk match the
1531         doc!
1532
1533 Thu Jan 12 15:02:40 1995  Stu Grossman  (grossman@cygnus.com)
1534
1535         * gdbtk.c, gdbtk.tcl:  Update/add copyright.
1536         * gdbtk.tcl (build_framework):  Several fixes for filespec widget,
1537         including dismiss button, and better error handling.
1538         * (create_command_win):  Bind button 2 to retrieve selection.
1539
1540 Wed Jan 11 17:06:55 1995  Stu Grossman  (grossman@cygnus.com)
1541
1542         * gdbtk.tcl:  Add button to control mixed source disassembly.
1543         Use text widgets in expr window.  The give me more control over
1544         layout.
1545         Add auto-updating of exprs in expression window.
1546         Handle expressions out of scope a bit better.
1547         Make selected window pop up to the top when invoked via the
1548         menubar.
1549         Make copyright message have raised relief.
1550
1551         * gdbtk.c (gdbtk_init):  Improve handling for errors in gdbtk.tcl
1552         during startup.
1553
1554 Thu Jan  5 17:38:29 1995  Stu Grossman  (grossman@cygnus.com)
1555
1556         * gdbtk.c (finish_saving_output):  Don't do anything if not saving
1557         output.
1558         * (breakpoint_notify):  Don't send null filename to tcl.
1559         * (gdb_eval):  New tcl command to eval an expression.
1560         * (gdb_disassemble):  New tcl command to do disassembly.  This
1561         allows tcl code to choose between exec file and target memeory,
1562         and can also do mixed source and assembly.
1563         * (gdbtk_init):  Move reading of gdbtk.tcl to the end to make sure
1564         that more of the environment is set up.  Also, create link between
1565         gdb and tcl vars disassemble{-_}from{-_}exec.
1566
1567         * gdbtk.tcl:  New expression window support.
1568         * Make assembly window be 80 columns wide.

1575
1576         * Pop up a copyright window on startup.
1577
1578 Wed Jan  4 19:49:10 1995  Stan Shebs  <shebs@andros.cygnus.com>
1579
1580         * gdbtk.tcl (build_framework): Add standard commands menu, more
1581         windows to standard windows menu.
1582         (not_implemented_yet): Clarify message.
1583
1584 Fri Dec 30 15:49:00 1994  Stan Shebs  <shebs@andros.cygnus.com>

1588         (build_framework): Add various file commands to file menu.
1589
1590 Fri Dec 23 16:18:50 1994  Stu Grossman  (grossman@cygnus.com)
1591
1592         * gdbtk.c (gdbtk_wait gdbtk_init):  Portability improvements for
1593         SIGIO handling.

1599
1600 Sun Dec 18 23:31:20 1994  Stu Grossman  (grossman@cygnus.com)
1601
1602         * gdbtk.c (gdbtk_wait gdbtk_init):  Use different method of
1603         enabling I/O interrupts for SVR4 (streams).
1604         * (start_saving_output save_output get_saved_output
1605         finish_saving_output flush_holdbuf gdbtk_flush gdbtk_fputs
1606         gdbtk_init):
1607         Totally revamp to use TCLs dynamic string functions.  Also, quote
1608         all data passed back to TCL to prevent errors with unmatched
1609         braces, odd characters, etc...  This fixes several wierd problems
1610         with outputting strings containing unmatched braces.
1611         * (breakpoint_notify gdb_loc):  Use long hex format to output
1612         addresses of breakpoints and PCs.  This fixes some Alpha problems.
1613         * (breakpoint_notify):  Add stream arg to call to gdbtk_fputs.
1614         * (gdb_listfiles):  Also, go through the symtabs when looking for
1615         files.  This makes xcoff work (sort of), but probably breaks
1616         something else.
1617         * (gdb_stop):  Return TCL_OK instead of nothing.  This fixes odd
1618         TCL errors when hitting stop button.
1619         * (tk_command):  Don't pass interp->result on to Tcl_{Var}Eval, as
1620         that will trash the result.  strdup the result instead and pass
1621         that on.  Improve error handling as well.
1622
1623         * gdbtk.tcl (gdbtk_tcl_flush):  Use global def of
1624         current_output_win.  Makes flushing actually work!
1625         * (asm_win_name create_asm_win update_assembly):  Bunch of fixes
1626         to make assembly windows stop flashing when loading a new file.
1627         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Use catch to prevent gdb_cmd
1628         errors from losing control.
1629         * (create_source_window):  Add source file selection to View menu.
1630         * (create_command_window (<Key-Return> binding):  Quote text fed
1631         into gdb_cmd to prevent eval errors.

1636         (full_filename): Remove.
1637         (gdb_cmd call_wrapper gdbtk_init): Protect all calls from tcl land
1638         with call_wrapper.  This prevents longjmps (usually via error())
1639         from jumping out of tcl/tk and leaving things in an indeterminate
1640         state.
1641         (gdbtk_fputs): Differentiate stdout from stderr when passing text
1642         into tcl land.
1643         * gdbtk.tcl: New view option to disable line numbers.  Put catch
1644         around most uses of gdb_cmd.  Add update button to reg config
1645         window.  Stop doing immediate updates when selecting registers.
1646         Change register view values into checkbuttons.
1647
1648 Mon Dec 12 16:59:29 1994  Stu Grossman  (grossman@cygnus.com)
1649
1650         * gdbtk.tcl (reg_config_menu create_registers_window
1651         recompute_reg_display_list):  Use array instead of individual vars
1652         for register display list.
1653         * (recompute_reg_display_list update_registers):  Fix bug with not
1654         displaying all registers.
1655
1656 Mon Dec 12 12:22:21 1994  Stu Grossman  (grossman@cygnus.com)
1657
1658         * gdbtk.c:  New tcl commands:  gdb_fetch_registers,
1659         gdb_changed_register_list, and gdb_regnames.
1660         * gdbtk.tcl:  Use monochrome color model for now.
1661         * (delete_breakpoint_tag create_file_win):  Add breakdot support.
1662         * (create_file_win create_asm_win update_listing build_framework
1663         create_source_window create_command_window):  Re-org window
1664         creation to give all windows consistent look and feel.
1665         * (update_listing update_asm):  Change pc pointer to '->'.
1666         * (registers_command reg_config_menu create_registers_window
1667         populate_reg_window update_registers):  Revamp register window.
1668         Allow selection of registers to be displayed.  Highlight changed
1669         registers.

1694
1695 Tue Nov  1 16:41:12 1994  Stu Grossman  (grossman@cygnus.com)
1696
1697         * Makefile.in:  Use $(objdir)/tcl and $(objdir)/tk if they are
1698         available.
1699         * configure.in (ENABLE_CLIBS):  Use $(TCL) and $(TK) instead of
1700         -ltcl and -ltk.
1701         * gdbtk.c:  Get rid of lots of unnecessary #includes.
1702         * (gdbtk_init):  Use ConnectionNumber macro instead of referencing

1704         * gdbtk.tcl:  Change exit button to quit button.
1705
1706 Wed Oct 26 15:41:07 1994  Stu Grossman  (grossman@cygnus.com)
1707
1708         * gdbtk.c: Change sense and name of no_windows variable.  Now

1716         waits.
1717         * (gdbtk_call_command):  Wrapper around command processing to
1718         alert GUI of target state changes.
1719         * (gdbtk_init):  Get the fd of X server for doing async
1720         notification of X events (via x_event).  Setup new hooks.
1721         * gdbtk.tcl:  Add scrollbars to assembly and command windows.
1722         * Change window foreground & background colors.
1723         * Create margin tag for breakpoints in source and assembly windows.
1724         * Add new routines to be invoked when target state changes to/from
1725         idle.
1726         * Add start of expression window.
1727         * Change bindings of mouse button 1 in assembly and source window
1728         to just set or clear breakpoints when in the margin tag.
1729         * Change shape of register window to be more vertical to better
1730         reflect its contents.
1731         * Add stop button.
1732         * Cleanup some code around command window bindings.

1735
1736         * gdbtk.tcl:  Let ^U delete lines in the command window.

1739
1740         * gdbtk.c:  Replace calls to full_filename with symtab_to_filename.
1741         * gdbtk.tcl:  New routine pc_to_line replaces in line code.  New
1742         routine decr replaces in line code.
1743         * (create_file_win):  Use catch to handle open failures more
1744         elegantly.  Also, create special window to display file open
1745         failure message.  Move opening of file prior to creation of text
1746         widget.
1747         * (create_asm_win):  Add PC as argument.  We now base disassembly
1748         on PC instead of function name, since function names can be
1749         ambiguous (usually seen with shared libs).  Also, use catch to
1750         simplify code where we don't care about failures.

1753
1754         * gdbtk.tcl:  Add ref counts to breakpoint tags.
1755         * Put quotes around function name in disassemble command to better
1756         handle assembler names containing `.'.
1757         * Make pclist element 0 be filler to avoid off-by-one problem with
1758         line numbers.
1759         * Set names of top-level windows.
1760         * Add register display window.
1761         * Add PC to label of assembly window.

1764
1765         * gdbtk.c (gdbtk_flush gdbtk_fputs):  Buffer up output to make
1766         disassembly more efficient.
1767         * (breakpoint_notify):  Include pc in gdbtk_tcl_breakpoint
1768         callback.
1769         * (gdb_loc):  Include pc in return value.  Also, return function
1770         name if arg was specified.
1771         * (gdb_cmd_stub):  Call gdb_flush to drain internal GDB buffers
1772         after command completes.
1773         * (gdbtk_init):  Improve error handling.
1774
1775         * gdbtk.tcl:  Add lots of comments.  Clean up code.
1776         * (gdbtk_tcl_fputs):  Make output window redirectable.
1777         * Add assembly window, and breapoint support.
1778         * Make button 1 in margin toggle breakpoints.
1779         * Use stippling to indicate breakpoint disabling.

1782
1783         * configure.in: Don't symlink to gdbtk.tcl if it's already there.

1785 Thu Jul 28 14:37:36 1994  Stu Grossman  (grossman@cygnus.com)
1786
1787         Support for TK GUI.
1788         * Makefile.in:  Add rule for gdbtk.o.
1789         * configure.in:  Add support for --enable-gdbtk.
1790         * gdbtk.c:  New file.  Contains support routines for TK interface.
1791         * gdbtk.tcl:  New file.  Implements GUI policy.
