        * configure.in (enable_gdbtk): If gdbtk, support the --x-includes
        and --x-libraries switches, setting the X11_INCLUDES and
        X11_LIB_SWITCHES respectively.  Instead of using a hardcoded -lX11
        in ENABLE_CLIBS, use the X11_LIB_SWITCHES and X11_LIBS variables.

        * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, don't use
        it.  This means that the stop button doesn't work, but is better
        than nothing.

Wed Mar 29 17:09:29 1995  Stu Grossman  (grossman@cygnus.com)

        * Makefile.in (gdbtk.o):  Use X11_CFLAGS to provide alternate
        locations (per-host) for X11 include files.
        * config/pa/hppahpux.mh (XM_CLIBS):  Add -L/usr/lib/X11R5 to force
        the use of R5 libs.
        (X11_CFLAGS):  Add this to indicate the locs
        of the R5 include files.

        type is not bp_breakpoint.

Tue Feb 14 17:16:41 1995  Stu Grossman  (grossman@cygnus.com)

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

        * gdbtk.c (gdb_disassemble): Deference pointer to function before
        calling it (pre-ANSI compilers generally require this).

Fri Feb  3 11:19:20 1995  Stu Grossman  (grossman@cygnus.com)

        * gdbtk.c (gdb_disassemble): Get rid of
        dis_asm_read_memory_hook.  We can now call the disassemblers
        directly and have no need for this hook anymore.

Mon Jan 30 17:34:24 1995  Stu Grossman  (grossman@cygnus.com)

        * gdbtk.tcl (create_file_win):  Disable old popup menu for source

        g++ caused by out-of-order pc's.
        * gdbtk.tcl (files_command):  Remove duplicate file names.  Also,
        add scrollbar.

Mon Jan 23 17:21:09 1995  Stu Grossman  (grossman@cygnus.com)

        * gdbtk.tcl:  Take .gdbtkinit if it exists.  Makes gdbtk match the
        doc!

        * gdbtk.c, gdbtk.tcl:  Update/add copyright.
        * gdbtk.tcl (build_framework):  Several fixes for filespec widget,
        including dismiss button, and better error handling.
        * (create_command_win):  Bind button 2 to retrieve selection.

        * gdbtk.tcl:  Add button to control mixed source disassembly.
        Use text widgets in expr window.  The give me more control over

        output.
        * (breakpoint_notify):  Don't send null filename to tcl.
        * (gdb_eval):  New tcl command to eval an expression.
        * (gdb_disassemble):  New tcl command to do disassembly.  This
        allows tcl code to choose between exec file and target memeory,
        and can also do mixed source and assembly.
        * (gdbtk_init):  Move reading of gdbtk.tcl to the end to make sure
        that more of the environment is set up.  Also, create link between
        gdb and tcl vars disassemble{-_}from{-_}exec.

        * gdbtk.tcl:  New expression window support.
        * Make assembly window be 80 columns wide.
        * Use new disassembly method.  Add menu items to select
        disassembly from exec file or target.

        * gdbtk.tcl (update_assembly):  Force update to make sure that pc
        is visible when creating new assembly windows.

Sun Dec 18 23:31:20 1994  Stu Grossman  (grossman@cygnus.com)

        * gdbtk.c (gdbtk_wait gdbtk_init):  Use different method of
        enabling I/O interrupts for SVR4 (streams).
        * (start_saving_output save_output get_saved_output
        finish_saving_output flush_holdbuf gdbtk_flush gdbtk_fputs
        gdbtk_init):
        Totally revamp to use TCLs dynamic string functions.  Also, quote
        all data passed back to TCL to prevent errors with unmatched
        braces, odd characters, etc...  This fixes several wierd problems
        with outputting strings containing unmatched braces.
        * (breakpoint_notify gdb_loc):  Use long hex format to output
        addresses of breakpoints and PCs.  This fixes some Alpha problems.
        * (breakpoint_notify):  Add stream arg to call to gdbtk_fputs.
        * (gdb_listfiles):  Also, go through the symtabs when looking for
        files.  This makes xcoff work (sort of), but probably breaks
        something else.
        * (gdb_stop):  Return TCL_OK instead of nothing.  This fixes odd
        TCL errors when hitting stop button.
        * (tk_command):  Don't pass interp->result on to Tcl_{Var}Eval, as
        that will trash the result.  strdup the result instead and pass
        that on.  Improve error handling as well.

        * gdbtk.tcl (gdbtk_tcl_flush):  Use global def of
        current_output_win.  Makes flushing actually work!
        * (asm_win_name create_asm_win update_assembly):  Bunch of fixes
        to make assembly windows stop flashing when loading a new file.
        * (gdbtk_tcl_busy gdbtk_tcl_idle):  Use catch to prevent gdb_cmd
        errors from losing control.
        * (create_source_window):  Add source file selection to View menu.
        * (create_command_window (<Key-Return> binding):  Quote text fed
        into gdb_cmd to prevent eval errors.

Thu Dec 15 16:40:10 1994  Stu Grossman  (grossman@cygnus.com)

        * gdbtk.c: Improve mechanism for capturing output values.
        (full_filename): Remove.
        (gdb_cmd call_wrapper gdbtk_init): Protect all calls from tcl land

        from jumping out of tcl/tk and leaving things in an indeterminate
        state.
        (gdbtk_fputs): Differentiate stdout from stderr when passing text
        into tcl land.
        * gdbtk.tcl: New view option to disable line numbers.  Put catch
        around most uses of gdb_cmd.  Add update button to reg config
        window.  Stop doing immediate updates when selecting registers.
        Change register view values into checkbuttons.

        for register display list.
        * (recompute_reg_display_list update_registers):  Fix bug with not

        gdb_changed_register_list, and gdb_regnames.
        * gdbtk.tcl:  Use monochrome color model for now.
        * (delete_breakpoint_tag create_file_win):  Add breakdot support.
        * (create_file_win create_asm_win update_listing build_framework
        create_source_window create_command_window):  Re-org window
        creation to give all windows consistent look and feel.
        * (update_listing update_asm):  Change pc pointer to '->'.
        * (registers_command reg_config_menu create_registers_window
        populate_reg_window update_registers):  Revamp register window.
        Allow selection of registers to be displayed.  Highlight changed
        registers.

Tue Nov  1 16:41:12 1994  Stu Grossman  (grossman@cygnus.com)

        * Makefile.in:  Use $(objdir)/tcl and $(objdir)/tk if they are
        available.
        * configure.in (ENABLE_CLIBS):  Use $(TCL) and $(TK) instead of
        -ltcl and -ltk.
        * gdbtk.c:  Get rid of lots of unnecessary #includes.
        * (gdbtk_init):  Use ConnectionNumber macro instead of referencing
        Display structure directly.
        * gdbtk.tcl:  Change exit button to quit button.

Wed Oct 26 15:41:07 1994  Stu Grossman  (grossman@cygnus.com)

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

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

Sat Sep 17 17:05:14 1994  Stu Grossman  (grossman@cygnus.com)

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

Fri Sep 16 15:40:34 1994  Stu Grossman  (grossman@cygnus.com)

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

Wed Sep 14 00:55:26 1994  Stu Grossman  (grossman@cygnus.com)

        * gdbtk.tcl:  Add ref counts to breakpoint tags.
        * Put quotes around function name in disassemble command to better
        handle assembler names containing `.'.

        line numbers.
        * Set names of top-level windows.
        * Add register display window.

        disassembly more efficient.
        * (breakpoint_notify):  Include pc in gdbtk_tcl_breakpoint
        callback.
        * (gdb_loc):  Include pc in return value.  Also, return function
        name if arg was specified.
        * (gdb_cmd_stub):  Call gdb_flush to drain internal GDB buffers
        after command completes.
        * (gdbtk_init):  Improve error handling.
