Changes to account for name change from cygwin32 to cygwin and
clean up Win32-related ifdefs.
* configure.tgt: check for cygwin* instead of cygwin32.
New cygwin gdb_target variable loses the "32".
* configure.host: check for cygwin* instead of cygwin32.
New cygwin gdb_host variable loses the "32".
* configure.in: test __CYGWIN__ instead of __CYGWIN32__,
rename gdb_cv_os_cygwin32 variable to drop the "32". Call
AM_EXEEXT instead of AC_EXEEXT since that isn't in a released
autoconf yet.
* configure: regenerate.
* main.c: drop "32" from cygwin_ funcs, include sys/cygwin.h
where
cygwin path conv protos live, instead of adding a proto here
for
them here.
* {main.c, ser-tcp.c, ser-unix.c, top.c}: check __CYGWIN__
instead of __CYGWIN32__.
* source.c: thoughout, check _WIN32 instead of WIN32.
* config/i386/cygwin32.mh: delete.
* config/i386/cygwin.mh: new file, was cygwin32.mh.

* (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.

Sat Mar 21 19:34:49 1998 Elena Zannoni <ezannoni@kwikemart.cygnus.com>
merged changes from Foundry (list follows by file/author):
- Tom Tromey <tromey@cygnus.com>
* Makefile.in (gdbres.o): New target.
(WINDRES): New define.
* configure: Rebuilt.
* configure.in (WINDRES): Define.
(CONFIG_OBS): Include gdbres.o on Windows.
* gdbtool.ico: New file.
* gdb.rc: New file.
* ser-unix.c
- Keith Seitz <keiths@onions.cygnus.com>
(wait_for): Don't reset the timeout_remaining for CYGWIN32,
since we now effectively poll the serial port.
Don't reset the current_timeout, either, since this member is used
by hardwire_readchar to track the timeout and call the ui_loop_hook.
(hardwire_readchar): Poll the serial port for Cygwin32. We timeout every
second, update the UI, and loop around doing this until we have hit the real
timeout or we get data or an error. This will allow the UI to stay active
while gdb is "blocked" talking to the target.
- Martin M. Hunt <hunt@cygnus.com>
(wait_for): Do reset current_timeout
because it is only used to keep track of what the
current timeout for the scb is.
* top.c
- Martin M. Hunt <hunt@cygnus.com>
(quit_confirm): Change exit message again
for GUI.
(pc_changed_hook): Add prototype.
- Tom Tromey <tromey@cygnus.com>
(quit_confirm): Added missing `else'.
(quit_confirm): Special-case message if init_ui_hook is
set.
* symtab.c
- Martin M. Hunt <hunt@cygnus.com>
(find_pc_sect_line): If no symbol information
is found, return correct pc anyway.
(find_methods): Comment out an apparently
bogus error message because it messes up Foundry.
* serial.c
- Martin M. Hunt <hunt@cygnus.com>
(_initialize_serial): Add a description of
"set remotelogbase".
* findvar.c
- Martin M. Hunt <hunt@cygnus.com>
(write_register_gen): Add call to
pc_changed_hook if the PC is being changed.
* defs.h
- Martin M. Hunt <hunt@cygnus.com>
(pc_changed_hook): Define.
* command.c
- Martin M. Hunt <hunt@cygnus.com>
(do_setshow_command): If no arguments are supplied,
don't dump core, instead print out an error message.
* breakpoint.c
- Martin M. Hunt <hunt@cygnus.com>
Make set_raw_breakpoint, set_breakpoint_count,
and breakpoint_count non-static so they are accessible from
gdbtk.c.
(enable_breakpoint): Enable breakpoint
with same disposition instead of changing all breakpoints
to donttouch.
* annotate.h
- Keith Seitz <keiths@onions.cygnus.com>
Add declarations for annotation hooks.
* annotate.c
- Keith Seitz <keiths@onions.cygnus.com>
Add hooks: annotate_starting_hook, annotate_stopped_hook,
annotate_signalled_hook, annotate_exited_hook.
(annotate_starting): If hook exists, call it instead.
(annotate_stopped): If hook exists, call it instead.
(annotate_exited): If hook exists, call it instead.
(annotate_signalled): If hook exists, call it instead.

lines. I don't know if this really works because
I don't have enough memory to test it.

(gdb_loadfile): New function. Takes a text widget
and loads it with the contents of a file. Marks
and tags source lines.

Sat Mar 21 19:34:49 1998 Elena Zannoni <ezannoni@kwikemart.cygnus.com>
merged changes from Foundry (list follows by file/author):
- Tom Tromey <tromey@cygnus.com>
* Makefile.in (gdbres.o): New target.
(WINDRES): New define.
* configure: Rebuilt.
* configure.in (WINDRES): Define.
(CONFIG_OBS): Include gdbres.o on Windows.
* gdbtool.ico: New file.
* gdb.rc: New file.
* ser-unix.c
- Keith Seitz <keiths@onions.cygnus.com>
(wait_for): Don't reset the timeout_remaining for CYGWIN32,
since we now effectively poll the serial port.
Don't reset the current_timeout, either, since this member is used
by hardwire_readchar to track the timeout and call the ui_loop_hook.
(hardwire_readchar): Poll the serial port for Cygwin32. We timeout every
second, update the UI, and loop around doing this until we have hit the real
timeout or we get data or an error. This will allow the UI to stay active
while gdb is "blocked" talking to the target.
- Martin M. Hunt <hunt@cygnus.com>
(wait_for): Do reset current_timeout
because it is only used to keep track of what the
current timeout for the scb is.
* top.c
- Martin M. Hunt <hunt@cygnus.com>
(quit_confirm): Change exit message again
for GUI.
(pc_changed_hook): Add prototype.
- Tom Tromey <tromey@cygnus.com>
(quit_confirm): Added missing `else'.
(quit_confirm): Special-case message if init_ui_hook is
set.
* symtab.c
- Martin M. Hunt <hunt@cygnus.com>
(find_pc_sect_line): If no symbol information
is found, return correct pc anyway.
(find_methods): Comment out an apparently
bogus error message because it messes up Foundry.
* serial.c
- Martin M. Hunt <hunt@cygnus.com>
(_initialize_serial): Add a description of
"set remotelogbase".
* findvar.c
- Martin M. Hunt <hunt@cygnus.com>
(write_register_gen): Add call to
pc_changed_hook if the PC is being changed.
* defs.h
- Martin M. Hunt <hunt@cygnus.com>
(pc_changed_hook): Define.
* command.c
- Martin M. Hunt <hunt@cygnus.com>
(do_setshow_command): If no arguments are supplied,
don't dump core, instead print out an error message.
* breakpoint.c
- Martin M. Hunt <hunt@cygnus.com>
Make set_raw_breakpoint, set_breakpoint_count,
and breakpoint_count non-static so they are accessible from
gdbtk.c.
(enable_breakpoint): Enable breakpoint
with same disposition instead of changing all breakpoints
to donttouch.
* annotate.h
- Keith Seitz <keiths@onions.cygnus.com>
Add declarations for annotation hooks.
* annotate.c
- Keith Seitz <keiths@onions.cygnus.com>
Add hooks: annotate_starting_hook, annotate_stopped_hook,
annotate_signalled_hook, annotate_exited_hook.
(annotate_starting): If hook exists, call it instead.
(annotate_stopped): If hook exists, call it instead.
(annotate_exited): If hook exists, call it instead.
(annotate_signalled): If hook exists, call it instead.

(CONFIG_OBS): Include gdbres.o on Windows.
* gdbtool.ico: New file.
* gdb.rc: New file.
* gdbtk.c (gdbtk_init): Call ide_create_messagebox_command.
(gdbtk_cleanup): Call ide_interface_deregister_all.
(gdbtk_init): Pass event handle to cleanup.
(TclDebug): Use Tcl_Merge to construct command.
(gdbtk_init): Call ide_create_cygwin_path_command.
- Martin M. Hunt <hunt@cygnus.com>
* gdbtk.c (gdb_set_bp): Set addr_string for bp.
(gdb_get_breakpoint_info): Demangle function
names in breakpoint info.
Include "demangle.h".
(gdb_loc, gdb_listfuncs): Demangle C++
function names.
(gdb_set_bp): Properly quote filename to fix
problems with spaces. Send pc back as a hex string.
(gdb_listfuncs): Remove debugging line.
Turn off some debugging lines.
(breakpoint_notify): Return correct line number.
(gdb_get_breakpoint_info): Return correct line number.
(gdb_set_bp): New function to provide a better way to
set breakpoints.
(gdbtk_readline, gdbtk_readline_begin): Memory
allocated by tcl needs to be freed by Tcl_Free().
(find_file_in_dir): Deleted.
(gdb_find_file_command): Call full_lookup_symtab().
(gdb_listfuncs): Call full_lookup_symtab().
(full_lookup_symtab): New function. Like lookup_symtab
except handles multiple files with the same basename,
full pathnames, and always sets symtab->fullname.
(gdb_loadfile): Call full_lookup_symtab(). Clear
realloc'd memory.
(gdb_loadfile): Don't tag lines without source.
Tag source lines with source_tag.
(gdb_find_file_command, find_file_in_dir):
Rewrite. Now searches symtabs and psymtabs for a match
on the partial or full filename. Returns the full pathname.
(gdb_loadfile): Realloc additional memory
if someone loads in a file with more than 160,000
lines. I don't know if this really works because
I don't have enough memory to test it.
(gdb_sourcelines): Deleted.
(gdb_loadfile): New function. Takes a text widget
and loads it with the contents of a file. Marks
and tags source lines.
(pc_changed): New function.
(get_pc_register): Returns the value of
the PC to GDB.
(gdb_loc): If looking on the stack, return
real pc along with calling source line.
(gdb_loc): Return "" instead of "N/A" if
filename is not found.
(gdb_get_breakpoint_info): Same.
