  24         error message from the result to the error_string.
  25         (gdbtk_fputs): add comments.
  26         (gdb_actions_command): call validate_actionline when installing the
  27         tracepoint, to do the syntax checking of the actions for us.
  28         - Elena Zannoni  <ezannoni@kwikemart.cygnus.com>
  29         (gdb_get_trace_frame_num): new function to get the
  30         trace frame number from gdb.

  34         be a Tcl_ObjCmdProc, not an Tcl_CmdProc, since it accepts a vector
  35         of objects as arguments.  Change the object vector to be const,
  36         since that's what all the users of this structure seem to expect.

  52         we can use this member to track real timeouts.
  53         (hardwire_readchar): Modify for cygwin32 so that we only ever use a real
  54         system timeout of one second. Track the "real" timeout as a series of these
  55         one second timeouts.
  56         Call ui_loop_hook to keep the gui alive.
  57
  58         * top.c: Define new hook for cygwin32, "ui_loop_hook".

  72         console-mode command line.
  73
  74 Wed May 13 11:12:58 1998  James Ingham  <jingham@leda.cygnus.com>
  75
  76         * gdbtk.c: Fixed a goof in the definition of the gdb_get_args &
  77         gdb_get_locals Tcl commands.  Moved the previous ChangeLog entry

  88         commands.  This way the obj commands will also go through
  89         catch_errors.  This is just a bandaid while I rewrite the
  90         string-based commands to use the object format.

1202
1203         * gdbtk.c: Conditionalize use of stdarg rather than varargs on

1207 Thu May 18 15:58:46 1995  J.T. Conklin  <jtc@rtl.cygnus.com>

1228         * Makefile.in (X11_INCLUDES): Define as empty.
1229         (X11_CFLAGS): Define as including $(X11_INCLUDES).
1230         (X11_LIB_SWITCHES): Define as empty.
1231         (X11_LIBS): Define as -lX11.
1232
1233         * configure.in (enable_gdbtk): If gdbtk, support the --x-includes
1234         and --x-libraries switches, setting the X11_INCLUDES and
1235         X11_LIB_SWITCHES respectively.  Instead of using a hardcoded -lX11
1236         in ENABLE_CLIBS, use the X11_LIB_SWITCHES and X11_LIBS variables.
1237
1238         * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, don't use
1239         it.  This means that the stop button doesn't work, but is better
1240         than nothing.
1241
1242 Wed Mar 29 17:09:29 1995  Stu Grossman  (grossman@cygnus.com)
1243

1246         * config/pa/hppahpux.mh (XM_CLIBS):  Add -L/usr/lib/X11R5 to force
1247         the use of R5 libs.
1248         (X11_CFLAGS):  Add this to indicate the locs
1249         of the R5 include files.
1250

1254         type is not bp_breakpoint.
1255

1257
1258         * gdbtk.c: Ditto.
1259         * gdbtk.c: General cleanups, get rid of unused variables.  Redo
1260         handling of stdout/stderr to just return output as the result of
1261         the tcl command that caused the output.  Cleanup -Wall stuff.
1262         * (breakpoint_notify):  Now returns just action and breakpoint
1263         number.
1264         * (gdb_get_breakpoint_list):  New routine.  Does the obvious.
1265         * (gdb_get_breakpoint_info):  Mostly derived from the old
1266         breakpoint_notify, but returns lots more info.
1267         * (dsprintf_append_element):  Helper routine, works like printf,
1268         but appends a tcl element onto the specified DString.  Good for
1269         building up lists as return values.
1270         * (gdbtk_enable/disable_breakpoint):  Go away.  Replaced with
1271         gdbtk_modify_breakpoint.
1272         * (*many routines*):  Use new result protocol.
1273         * (call_wrapper):  Make sure that recursive calls don't trash results.
1274         * gdbtk.tcl:  New windows, autocmd, and breakpoints.
1275         * (gdbtk_tcl_fputs):  Don't use $current_output_win redirection
1276         anymore.  It's not needed (in fact, this routine may not be needed
1277         anymore).
1278         * (gdbtk_tcl_breakpoint):  Change to reflect new breakpoint
1279         notification protocol.
1280         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Straighten out buttons, remove
1281         catches.
1282         * (interactive_cmd):  Use this wrapper around button invocations
1283         of many commands.  This will catch errors and put the results into
1284         the command window.  It also updates all the other windows.
1285         * Also, change reliefs of most things to sunken.  This actually
1286         looks better.
1287         * (create_file_win):  Fix margin binding to allow breakpoints to
1288         work again.
1289         * (create_asm_win):  Use return value of gdb_disassemble instead
1290         of implicit I/O to the command window.
1291         * (create_command_window):  Use new result protocol to get output
1292         from commands.

1294 Sun Feb  5 20:32:44 1995  Jim Kingdon  (kingdon@lioth.cygnus.com)
1295
1296         * gdbtk.c (gdb_disassemble): Deference pointer to function before
1297         calling it (pre-ANSI compilers generally require this).
1298
1299 Fri Feb  3 11:19:20 1995  Stu Grossman  (grossman@cygnus.com)
1300
1301         * gdbtk.c (gdb_disassemble): Get rid of
1302         dis_asm_read_memory_hook.  We can now call the disassemblers

1361         and can also do mixed source and assembly.
1362         * (gdbtk_init):  Move reading of gdbtk.tcl to the end to make sure

1383 Fri Dec 30 15:49:00 1994  Stan Shebs  <shebs@andros.cygnus.com>
1384
1385         * gdbtk.tcl (FSBox): New proc, File Selection Box code from exmh.
1386         (not_implemented_yet): New proc.
1387         (build_framework): Add various file commands to file menu.
1388
1389 Fri Dec 23 16:18:50 1994  Stu Grossman  (grossman@cygnus.com)
1390
1391         * gdbtk.c (gdbtk_wait gdbtk_init):  Portability improvements for
1392         SIGIO handling.
1393
1394 Mon Dec 19 09:55:47 1994  Stu Grossman  (grossman@cygnus.com)
1395
1396         * gdbtk.tcl (update_assembly):  Force update to make sure that pc
1397         is visible when creating new assembly windows.
1398
1399 Sun Dec 18 23:31:20 1994  Stu Grossman  (grossman@cygnus.com)
1400
1401         * gdbtk.c (gdbtk_wait gdbtk_init):  Use different method of
1402         enabling I/O interrupts for SVR4 (streams).
1403         * (start_saving_output save_output get_saved_output
1404         finish_saving_output flush_holdbuf gdbtk_flush gdbtk_fputs
1405         gdbtk_init):
1406         Totally revamp to use TCLs dynamic string functions.  Also, quote
1407         all data passed back to TCL to prevent errors with unmatched
1408         braces, odd characters, etc...  This fixes several wierd problems
1409         with outputting strings containing unmatched braces.
1410         * (breakpoint_notify gdb_loc):  Use long hex format to output
1411         addresses of breakpoints and PCs.  This fixes some Alpha problems.
1412         * (breakpoint_notify):  Add stream arg to call to gdbtk_fputs.
1413         * (gdb_listfiles):  Also, go through the symtabs when looking for
1414         files.  This makes xcoff work (sort of), but probably breaks
1415         something else.
1416         * (gdb_stop):  Return TCL_OK instead of nothing.  This fixes odd
1417         TCL errors when hitting stop button.
1418         * (tk_command):  Don't pass interp->result on to Tcl_{Var}Eval, as
1419         that will trash the result.  strdup the result instead and pass
1420         that on.  Improve error handling as well.
1421
1422         * gdbtk.tcl (gdbtk_tcl_flush):  Use global def of
1423         current_output_win.  Makes flushing actually work!
1424         * (asm_win_name create_asm_win update_assembly):  Bunch of fixes
1425         to make assembly windows stop flashing when loading a new file.
1426         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Use catch to prevent gdb_cmd
1427         errors from losing control.
1428         * (create_source_window):  Add source file selection to View menu.
1429         * (create_command_window (<Key-Return> binding):  Quote text fed
1430         into gdb_cmd to prevent eval errors.
1431
1432 Thu Dec 15 16:40:10 1994  Stu Grossman  (grossman@cygnus.com)
1433
1434         * gdbtk.c: Improve mechanism for capturing output values.
1435         (full_filename): Remove.
1436         (gdb_cmd call_wrapper gdbtk_init): Protect all calls from tcl land
1437         with call_wrapper.  This prevents longjmps (usually via error())
1438         from jumping out of tcl/tk and leaving things in an indeterminate
1439         state.
1440         (gdbtk_fputs): Differentiate stdout from stderr when passing text
1441         into tcl land.
1442         * gdbtk.tcl: New view option to disable line numbers.  Put catch
1443         around most uses of gdb_cmd.  Add update button to reg config
1444         window.  Stop doing immediate updates when selecting registers.
1445         Change register view values into checkbuttons.
1446
1447 Mon Dec 12 16:59:29 1994  Stu Grossman  (grossman@cygnus.com)
1448
1449         * gdbtk.tcl (reg_config_menu create_registers_window
1450         recompute_reg_display_list):  Use array instead of individual vars
1451         for register display list.
1452         * (recompute_reg_display_list update_registers):  Fix bug with not
1453         displaying all registers.
1454
1455 Mon Dec 12 12:22:21 1994  Stu Grossman  (grossman@cygnus.com)
1456
1457         * gdbtk.c:  New tcl commands:  gdb_fetch_registers,
1458         gdb_changed_register_list, and gdb_regnames.
1459         * gdbtk.tcl:  Use monochrome color model for now.
1460         * (delete_breakpoint_tag create_file_win):  Add breakdot support.
1461         * (create_file_win create_asm_win update_listing build_framework
1462         create_source_window create_command_window):  Re-org window
1463         creation to give all windows consistent look and feel.
1464         * (update_listing update_asm):  Change pc pointer to '->'.
1465         * (registers_command reg_config_menu create_registers_window
1466         populate_reg_window update_registers):  Revamp register window.
1467         Allow selection of registers to be displayed.  Highlight changed
1468         registers.
1469
1470 Mon Nov 28 09:17:20 1994  Stu Grossman  (grossman@cygnus.com)

1472         * gdbtk.tcl (build_framework):  Fix bug with setting window titles.
1473
1474         * gdbtk.tcl (build_framework):  Add "Report bug" to help menu.
1475
1476         * gdbtk.tcl:  Re-arrange windows using new, consistent layout. Clean
1477         up lots of code and centralize framework initialization.
1478

1488         containing code.  (gdb_regnames):  Returns list of register names.
1489
1490 Thu Nov  3 14:25:24 1994  Stu Grossman  (grossman@cygnus.com)
1491
1492         * gdbtk.c (gdb_stop):  Switch to target_stop().
1493
1494 Tue Nov  1 16:41:12 1994  Stu Grossman  (grossman@cygnus.com)
1495
1496         * Makefile.in:  Use $(objdir)/tcl and $(objdir)/tk if they are
1497         available.
1498         * configure.in (ENABLE_CLIBS):  Use $(TCL) and $(TK) instead of
1499         -ltcl and -ltk.
1500         * gdbtk.c:  Get rid of lots of unnecessary #includes.
1501         * (gdbtk_init):  Use ConnectionNumber macro instead of referencing

1506
1507         * gdbtk.c: Change sense and name of no_windows variable.  Now
1508         called use_windows, and defaults to off (for compatibility).

1512         * gdbtk.c (gdb_cmd):  Force GUI into idle mode when errors occur.
1513         * (gdb_stop):  New tcl command to stop the target process.
1514         * (x_event, gdbtk_wait):  Allow GUI to interrupt gdb out of target
1515         waits.
1516         * (gdbtk_call_command):  Wrapper around command processing to
1517         alert GUI of target state changes.
1518         * (gdbtk_init):  Get the fd of X server for doing async
1519         notification of X events (via x_event).  Setup new hooks.
1520         * gdbtk.tcl:  Add scrollbars to assembly and command windows.
1521         * Change window foreground & background colors.
1522         * Create margin tag for breakpoints in source and assembly windows.

1526         * Change bindings of mouse button 1 in assembly and source window
1527         to just set or clear breakpoints when in the margin tag.
1528         * Change shape of register window to be more vertical to better
1529         reflect its contents.
1530         * Add stop button.
1531         * Cleanup some code around command window bindings.
1532
1533 Sat Sep 17 17:05:14 1994  Stu Grossman  (grossman@cygnus.com)
1534
1535         * gdbtk.tcl:  Let ^U delete lines in the command window.
1536
1537 Fri Sep 16 15:40:34 1994  Stu Grossman  (grossman@cygnus.com)
1538

1540         * gdbtk.tcl:  New routine pc_to_line replaces in line code.  New
1541         routine decr replaces in line code.
1542         * (create_file_win):  Use catch to handle open failures more
1543         elegantly.  Also, create special window to display file open
1544         failure message.  Move opening of file prior to creation of text
1545         widget.
1546         * (create_asm_win):  Add PC as argument.  We now base disassembly
1547         on PC instead of function name, since function names can be

1554         * Put quotes around function name in disassemble command to better
1555         handle assembler names containing `.'.

1557         line numbers.
1558         * Set names of top-level windows.
1559         * Add register display window.
1560         * Add PC to label of assembly window.
