 836
 837         * gdbtk.tcl: ENABLE comes back as "1" or "0", not "enable" or

 861
 862         * gdbtk.c: Conditionalize use of stdarg rather than varargs on

 890         (X11_LIBS): Define as -lX11.
 891
 892         * configure.in (enable_gdbtk): If gdbtk, support the --x-includes
 893         and --x-libraries switches, setting the X11_INCLUDES and
 894         X11_LIB_SWITCHES respectively.  Instead of using a hardcoded -lX11
 895         in ENABLE_CLIBS, use the X11_LIB_SWITCHES and X11_LIBS variables.
 896
 897         * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, don't use

 902
 903         * Makefile.in (gdbtk.o):  Use X11_CFLAGS to provide alternate

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

 908         of the R5 include files.

 916
 917         * gdbtk.c: Ditto.
 918         * gdbtk.c: General cleanups, get rid of unused variables.  Redo
 919         handling of stdout/stderr to just return output as the result of
 920         the tcl command that caused the output.  Cleanup -Wall stuff.
 921         * (breakpoint_notify):  Now returns just action and breakpoint
 922         number.
 923         * (gdb_get_breakpoint_list):  New routine.  Does the obvious.
 924         * (gdb_get_breakpoint_info):  Mostly derived from the old

 926         * (dsprintf_append_element):  Helper routine, works like printf,
 927         but appends a tcl element onto the specified DString.  Good for
 928         building up lists as return values.
 929         * (gdbtk_enable/disable_breakpoint):  Go away.  Replaced with
 930         gdbtk_modify_breakpoint.
 931         * (*many routines*):  Use new result protocol.
 932         * (call_wrapper):  Make sure that recursive calls don't trash results.
 933         * gdbtk.tcl:  New windows, autocmd, and breakpoints.
 934         * (gdbtk_tcl_fputs):  Don't use $current_output_win redirection
 935         anymore.  It's not needed (in fact, this routine may not be needed
 936         anymore).
 937         * (gdbtk_tcl_breakpoint):  Change to reflect new breakpoint
 938         notification protocol.
 939         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Straighten out buttons, remove
 940         catches.
 941         * (interactive_cmd):  Use this wrapper around button invocations
 942         of many commands.  This will catch errors and put the results into
 943         the command window.  It also updates all the other windows.
 944         * Also, change reliefs of most things to sunken.  This actually
 945         looks better.
 946         * (create_file_win):  Fix margin binding to allow breakpoints to
 947         work again.
 948         * (create_asm_win):  Use return value of gdb_disassemble instead

 950         * (create_command_window):  Use new result protocol to get output
 951         from commands.

 959
 960         * gdbtk.c (gdb_disassemble): Get rid of

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

1021         * (gdbtk_init):  Move reading of gdbtk.tcl to the end to make sure

1059
1060         * gdbtk.c (gdbtk_wait gdbtk_init):  Use different method of
1061         enabling I/O interrupts for SVR4 (streams).
1062         * (start_saving_output save_output get_saved_output
1063         finish_saving_output flush_holdbuf gdbtk_flush gdbtk_fputs
1064         gdbtk_init):
1065         Totally revamp to use TCLs dynamic string functions.  Also, quote
1066         all data passed back to TCL to prevent errors with unmatched
1067         braces, odd characters, etc...  This fixes several wierd problems
1068         with outputting strings containing unmatched braces.
1069         * (breakpoint_notify gdb_loc):  Use long hex format to output
1070         addresses of breakpoints and PCs.  This fixes some Alpha problems.
1071         * (breakpoint_notify):  Add stream arg to call to gdbtk_fputs.
1072         * (gdb_listfiles):  Also, go through the symtabs when looking for
1073         files.  This makes xcoff work (sort of), but probably breaks
1074         something else.
1075         * (gdb_stop):  Return TCL_OK instead of nothing.  This fixes odd
1076         TCL errors when hitting stop button.
1077         * (tk_command):  Don't pass interp->result on to Tcl_{Var}Eval, as
1078         that will trash the result.  strdup the result instead and pass
1079         that on.  Improve error handling as well.
1080
1081         * gdbtk.tcl (gdbtk_tcl_flush):  Use global def of
1082         current_output_win.  Makes flushing actually work!
1083         * (asm_win_name create_asm_win update_assembly):  Bunch of fixes
1084         to make assembly windows stop flashing when loading a new file.
1085         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Use catch to prevent gdb_cmd
1086         errors from losing control.
1087         * (create_source_window):  Add source file selection to View menu.
1088         * (create_command_window (<Key-Return> binding):  Quote text fed
1089         into gdb_cmd to prevent eval errors.
1090
1091 Thu Dec 15 16:40:10 1994  Stu Grossman  (grossman@cygnus.com)
1092
1093         * gdbtk.c: Improve mechanism for capturing output values.
1094         (full_filename): Remove.
1095         (gdb_cmd call_wrapper gdbtk_init): Protect all calls from tcl land
1096         with call_wrapper.  This prevents longjmps (usually via error())
1097         from jumping out of tcl/tk and leaving things in an indeterminate
1098         state.
1099         (gdbtk_fputs): Differentiate stdout from stderr when passing text
1100         into tcl land.
1101         * gdbtk.tcl: New view option to disable line numbers.  Put catch
1102         around most uses of gdb_cmd.  Add update button to reg config
1103         window.  Stop doing immediate updates when selecting registers.
1104         Change register view values into checkbuttons.
1105
1106 Mon Dec 12 16:59:29 1994  Stu Grossman  (grossman@cygnus.com)
1107
1108         * gdbtk.tcl (reg_config_menu create_registers_window
1109         recompute_reg_display_list):  Use array instead of individual vars
1110         for register display list.
1111         * (recompute_reg_display_list update_registers):  Fix bug with not
1112         displaying all registers.
1113
1114 Mon Dec 12 12:22:21 1994  Stu Grossman  (grossman@cygnus.com)
1115
1116         * gdbtk.c:  New tcl commands:  gdb_fetch_registers,
1117         gdb_changed_register_list, and gdb_regnames.
1118         * gdbtk.tcl:  Use monochrome color model for now.
1119         * (delete_breakpoint_tag create_file_win):  Add breakdot support.
1120         * (create_file_win create_asm_win update_listing build_framework
1121         create_source_window create_command_window):  Re-org window
1122         creation to give all windows consistent look and feel.
1123         * (update_listing update_asm):  Change pc pointer to '->'.
1124         * (registers_command reg_config_menu create_registers_window
1125         populate_reg_window update_registers):  Revamp register window.
1126         Allow selection of registers to be displayed.  Highlight changed
1127         registers.
1128
1129 Mon Nov 28 09:17:20 1994  Stu Grossman  (grossman@cygnus.com)
1130
1131         * gdbtk.tcl (build_framework):  Fix bug with setting window titles.
1132
1133         * gdbtk.tcl (build_framework):  Add "Report bug" to help menu.
1134
1135         * gdbtk.tcl:  Re-arrange windows using new, consistent layout. Clean
1136         up lots of code and centralize framework initialization.
1137
1138 Wed Nov 16 15:28:29 1994  Rob Savoye  (rob@cygnus.com)

1145         * configure.in:  Add ENABLE_GDBTK flag.
1146         * gdbtk.c (gdb_sourcelines):  Returns list of source lines
1147         containing code.  (gdb_regnames):  Returns list of register names.
1148
1149 Thu Nov  3 14:25:24 1994  Stu Grossman  (grossman@cygnus.com)
1150
1151         * gdbtk.c (gdb_stop):  Switch to target_stop().
1152
1153 Tue Nov  1 16:41:12 1994  Stu Grossman  (grossman@cygnus.com)
1154
1155         * Makefile.in:  Use $(objdir)/tcl and $(objdir)/tk if they are
1156         available.
1157         * configure.in (ENABLE_CLIBS):  Use $(TCL) and $(TK) instead of
1158         -ltcl and -ltk.
1159         * gdbtk.c:  Get rid of lots of unnecessary #includes.
1160         * (gdbtk_init):  Use ConnectionNumber macro instead of referencing
1161         Display structure directly.
1162         * gdbtk.tcl:  Change exit button to quit button.
1163
1164 Wed Oct 26 15:41:07 1994  Stu Grossman  (grossman@cygnus.com)
1165
1166         * gdbtk.c: Change sense and name of no_windows variable.  Now
1167         called use_windows, and defaults to off (for compatibility).
1168
1169 Thu Oct 20 17:35:45 1994  Stu Grossman  (grossman@cygnus.com)
1170
1171         * gdbtk.c (gdb_cmd):  Force GUI into idle mode when errors occur.
1172         * (gdb_stop):  New tcl command to stop the target process.
1173         * (x_event, gdbtk_wait):  Allow GUI to interrupt gdb out of target
1174         waits.
1175         * (gdbtk_call_command):  Wrapper around command processing to
1176         alert GUI of target state changes.
1177         * (gdbtk_init):  Get the fd of X server for doing async
1178         notification of X events (via x_event).  Setup new hooks.
1179         * gdbtk.tcl:  Add scrollbars to assembly and command windows.
1180         * Change window foreground & background colors.
1181         * Create margin tag for breakpoints in source and assembly windows.
1182         * Add new routines to be invoked when target state changes to/from
1183         idle.
1184         * Add start of expression window.
1185         * Change bindings of mouse button 1 in assembly and source window
1186         to just set or clear breakpoints when in the margin tag.
1187         * Change shape of register window to be more vertical to better
1188         reflect its contents.
1189         * Add stop button.
1190         * Cleanup some code around command window bindings.
1191
1192 Sat Sep 17 17:05:14 1994  Stu Grossman  (grossman@cygnus.com)
1193
1194         * gdbtk.tcl:  Let ^U delete lines in the command window.
1195
1196 Fri Sep 16 15:40:34 1994  Stu Grossman  (grossman@cygnus.com)
1197
1198         * gdbtk.c:  Replace calls to full_filename with symtab_to_filename.
1199         * gdbtk.tcl:  New routine pc_to_line replaces in line code.  New
1200         routine decr replaces in line code.
1201         * (create_file_win):  Use catch to handle open failures more
1202         elegantly.  Also, create special window to display file open
1203         failure message.  Move opening of file prior to creation of text
1204         widget.
1205         * (create_asm_win):  Add PC as argument.  We now base disassembly
1206         on PC instead of function name, since function names can be
1207         ambiguous (usually seen with shared libs).  Also, use catch to
1208         simplify code where we don't care about failures.
1209

1211
1212         * gdbtk.tcl:  Add ref counts to breakpoint tags.
1213         * Put quotes around function name in disassemble command to better
1214         handle assembler names containing `.'.
1215         * Make pclist element 0 be filler to avoid off-by-one problem with
1216         line numbers.
1217         * Set names of top-level windows.
1218         * Add register display window.
1219         * Add PC to label of assembly window.
1220
1221 Tue Sep 13 08:59:04 1994  Stu Grossman  (grossman@cygnus.com)

1224         disassembly more efficient.
1225         * (breakpoint_notify):  Include pc in gdbtk_tcl_breakpoint
1226         callback.
1227         * (gdb_loc):  Include pc in return value.  Also, return function
1228         name if arg was specified.

1240
1241         * configure.in: Don't symlink to gdbtk.tcl if it's already there.
1242
1243 Thu Jul 28 14:37:36 1994  Stu Grossman  (grossman@cygnus.com)
1244
1245         Support for TK GUI.
1246         * Makefile.in:  Add rule for gdbtk.o.
1247         * configure.in:  Add support for --enable-gdbtk.
1248         * gdbtk.c:  New file.  Contains support routines for TK interface.
