 843
 844         * gdbtk.tcl: ENABLE comes back as "1" or "0", not "enable" or

 868
 869         * gdbtk.c: Conditionalize use of stdarg rather than varargs on

 891
 892 Thu Apr  6 17:00:46 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
 893
 894         * Makefile.in (X11_INCLUDES): Define as empty.

 897         (X11_LIBS): Define as -lX11.
 898
 899         * configure.in (enable_gdbtk): If gdbtk, support the --x-includes
 900         and --x-libraries switches, setting the X11_INCLUDES and
 901         X11_LIB_SWITCHES respectively.  Instead of using a hardcoded -lX11
 902         in ENABLE_CLIBS, use the X11_LIB_SWITCHES and X11_LIBS variables.
 903
 904         * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, don't use
 905         it.  This means that the stop button doesn't work, but is better
 906         than nothing.
 907
 908 Wed Mar 29 17:09:29 1995  Stu Grossman  (grossman@cygnus.com)
 909
 910         * Makefile.in (gdbtk.o):  Use X11_CFLAGS to provide alternate

 912         * config/pa/hppahpux.mh (XM_CLIBS):  Add -L/usr/lib/X11R5 to force

 915         of the R5 include files.

 923
 924         * gdbtk.c: Ditto.
 925         * gdbtk.c: General cleanups, get rid of unused variables.  Redo
 926         handling of stdout/stderr to just return output as the result of
 927         the tcl command that caused the output.  Cleanup -Wall stuff.
 928         * (breakpoint_notify):  Now returns just action and breakpoint
 929         number.
 930         * (gdb_get_breakpoint_list):  New routine.  Does the obvious.
 931         * (gdb_get_breakpoint_info):  Mostly derived from the old
 932         breakpoint_notify, but returns lots more info.
 933         * (dsprintf_append_element):  Helper routine, works like printf,
 934         but appends a tcl element onto the specified DString.  Good for
 935         building up lists as return values.
 936         * (gdbtk_enable/disable_breakpoint):  Go away.  Replaced with
 937         gdbtk_modify_breakpoint.
 938         * (*many routines*):  Use new result protocol.
 939         * (call_wrapper):  Make sure that recursive calls don't trash results.
 940         * gdbtk.tcl:  New windows, autocmd, and breakpoints.
 941         * (gdbtk_tcl_fputs):  Don't use $current_output_win redirection
 942         anymore.  It's not needed (in fact, this routine may not be needed
 943         anymore).
 944         * (gdbtk_tcl_breakpoint):  Change to reflect new breakpoint
 945         notification protocol.
 946         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Straighten out buttons, remove
 947         catches.
 948         * (interactive_cmd):  Use this wrapper around button invocations
 949         of many commands.  This will catch errors and put the results into
 950         the command window.  It also updates all the other windows.
 951         * Also, change reliefs of most things to sunken.  This actually
 952         looks better.
 953         * (create_file_win):  Fix margin binding to allow breakpoints to
 954         work again.
 955         * (create_asm_win):  Use return value of gdb_disassemble instead
 956         of implicit I/O to the command window.
 957         * (create_command_window):  Use new result protocol to get output
 958         from commands.

 960 Sun Feb  5 20:32:44 1995  Jim Kingdon  (kingdon@lioth.cygnus.com)
 961
 962         * gdbtk.c (gdb_disassemble): Deference pointer to function before
 963         calling it (pre-ANSI compilers generally require this).

 966
 967         * gdbtk.c (gdb_disassemble): Get rid of

 989         g++ caused by out-of-order pc's.

1011         Handle expressions out of scope a bit better.

1027         and can also do mixed source and assembly.
1028         * (gdbtk_init):  Move reading of gdbtk.tcl to the end to make sure

1055 Fri Dec 23 16:18:50 1994  Stu Grossman  (grossman@cygnus.com)
1056
1057         * gdbtk.c (gdbtk_wait gdbtk_init):  Portability improvements for
1058         SIGIO handling.
1059
1060 Mon Dec 19 09:55:47 1994  Stu Grossman  (grossman@cygnus.com)
1061
1062         * gdbtk.tcl (update_assembly):  Force update to make sure that pc
1063         is visible when creating new assembly windows.
1064
1065 Sun Dec 18 23:31:20 1994  Stu Grossman  (grossman@cygnus.com)
1066
1067         * gdbtk.c (gdbtk_wait gdbtk_init):  Use different method of
1068         enabling I/O interrupts for SVR4 (streams).
1069         * (start_saving_output save_output get_saved_output
1070         finish_saving_output flush_holdbuf gdbtk_flush gdbtk_fputs
1071         gdbtk_init):
1072         Totally revamp to use TCLs dynamic string functions.  Also, quote
1073         all data passed back to TCL to prevent errors with unmatched
1074         braces, odd characters, etc...  This fixes several wierd problems
1075         with outputting strings containing unmatched braces.
1076         * (breakpoint_notify gdb_loc):  Use long hex format to output
1077         addresses of breakpoints and PCs.  This fixes some Alpha problems.
1078         * (breakpoint_notify):  Add stream arg to call to gdbtk_fputs.
1079         * (gdb_listfiles):  Also, go through the symtabs when looking for
1080         files.  This makes xcoff work (sort of), but probably breaks
1081         something else.
1082         * (gdb_stop):  Return TCL_OK instead of nothing.  This fixes odd
1083         TCL errors when hitting stop button.
1084         * (tk_command):  Don't pass interp->result on to Tcl_{Var}Eval, as
1085         that will trash the result.  strdup the result instead and pass
1086         that on.  Improve error handling as well.
1087
1088         * gdbtk.tcl (gdbtk_tcl_flush):  Use global def of
1089         current_output_win.  Makes flushing actually work!
1090         * (asm_win_name create_asm_win update_assembly):  Bunch of fixes
1091         to make assembly windows stop flashing when loading a new file.
1092         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Use catch to prevent gdb_cmd
1093         errors from losing control.
1094         * (create_source_window):  Add source file selection to View menu.
1095         * (create_command_window (<Key-Return> binding):  Quote text fed
1096         into gdb_cmd to prevent eval errors.
1097
1098 Thu Dec 15 16:40:10 1994  Stu Grossman  (grossman@cygnus.com)
1099
1100         * gdbtk.c: Improve mechanism for capturing output values.
1101         (full_filename): Remove.
1102         (gdb_cmd call_wrapper gdbtk_init): Protect all calls from tcl land
1103         with call_wrapper.  This prevents longjmps (usually via error())
1104         from jumping out of tcl/tk and leaving things in an indeterminate
1105         state.
1106         (gdbtk_fputs): Differentiate stdout from stderr when passing text
1107         into tcl land.
1108         * gdbtk.tcl: New view option to disable line numbers.  Put catch
1109         around most uses of gdb_cmd.  Add update button to reg config
1110         window.  Stop doing immediate updates when selecting registers.
1111         Change register view values into checkbuttons.
1112
1113 Mon Dec 12 16:59:29 1994  Stu Grossman  (grossman@cygnus.com)
1114
1115         * gdbtk.tcl (reg_config_menu create_registers_window
1116         recompute_reg_display_list):  Use array instead of individual vars
1117         for register display list.
1118         * (recompute_reg_display_list update_registers):  Fix bug with not
1119         displaying all registers.
1120
1121 Mon Dec 12 12:22:21 1994  Stu Grossman  (grossman@cygnus.com)

1123         * gdbtk.c:  New tcl commands:  gdb_fetch_registers,
1124         gdb_changed_register_list, and gdb_regnames.
1125         * gdbtk.tcl:  Use monochrome color model for now.
1126         * (delete_breakpoint_tag create_file_win):  Add breakdot support.
1127         * (create_file_win create_asm_win update_listing build_framework
1128         create_source_window create_command_window):  Re-org window
1129         creation to give all windows consistent look and feel.
1130         * (update_listing update_asm):  Change pc pointer to '->'.
1131         * (registers_command reg_config_menu create_registers_window
1132         populate_reg_window update_registers):  Revamp register window.
1133         Allow selection of registers to be displayed.  Highlight changed
1134         registers.

1139
1140         * gdbtk.tcl (build_framework):  Add "Report bug" to help menu.
1141
1142         * gdbtk.tcl:  Re-arrange windows using new, consistent layout. Clean
1143         up lots of code and centralize framework initialization.

1154         containing code.  (gdb_regnames):  Returns list of register names.
1155
1156 Thu Nov  3 14:25:24 1994  Stu Grossman  (grossman@cygnus.com)
1157
1158         * gdbtk.c (gdb_stop):  Switch to target_stop().
1159
1160 Tue Nov  1 16:41:12 1994  Stu Grossman  (grossman@cygnus.com)
1161
1162         * Makefile.in:  Use $(objdir)/tcl and $(objdir)/tk if they are
1163         available.
1164         * configure.in (ENABLE_CLIBS):  Use $(TCL) and $(TK) instead of
1165         -ltcl and -ltk.
1166         * gdbtk.c:  Get rid of lots of unnecessary #includes.
1167         * (gdbtk_init):  Use ConnectionNumber macro instead of referencing

1172
1173         * gdbtk.c: Change sense and name of no_windows variable.  Now
1174         called use_windows, and defaults to off (for compatibility).

1178         * gdbtk.c (gdb_cmd):  Force GUI into idle mode when errors occur.
1179         * (gdb_stop):  New tcl command to stop the target process.
1180         * (x_event, gdbtk_wait):  Allow GUI to interrupt gdb out of target
1181         waits.
1182         * (gdbtk_call_command):  Wrapper around command processing to
1183         alert GUI of target state changes.
1184         * (gdbtk_init):  Get the fd of X server for doing async
1185         notification of X events (via x_event).  Setup new hooks.
1186         * gdbtk.tcl:  Add scrollbars to assembly and command windows.
1187         * Change window foreground & background colors.
1188         * Create margin tag for breakpoints in source and assembly windows.
1189         * Add new routines to be invoked when target state changes to/from
1190         idle.
1191         * Add start of expression window.
1192         * Change bindings of mouse button 1 in assembly and source window
1193         to just set or clear breakpoints when in the margin tag.
1194         * Change shape of register window to be more vertical to better
1195         reflect its contents.
1196         * Add stop button.
1197         * Cleanup some code around command window bindings.
1198

1200
1201         * gdbtk.tcl:  Let ^U delete lines in the command window.
1202
1203 Fri Sep 16 15:40:34 1994  Stu Grossman  (grossman@cygnus.com)
1204
1205         * gdbtk.c:  Replace calls to full_filename with symtab_to_filename.
1206         * gdbtk.tcl:  New routine pc_to_line replaces in line code.  New
1207         routine decr replaces in line code.
1208         * (create_file_win):  Use catch to handle open failures more
1209         elegantly.  Also, create special window to display file open
1210         failure message.  Move opening of file prior to creation of text
1211         widget.
1212         * (create_asm_win):  Add PC as argument.  We now base disassembly
1213         on PC instead of function name, since function names can be

1220         * Put quotes around function name in disassemble command to better
1221         handle assembler names containing `.'.

1223         line numbers.
1224         * Set names of top-level windows.
1225         * Add register display window.
1226         * Add PC to label of assembly window.
