but there's a stack adjust, then use that as the end of prologue.
(m32r_skip_prologue): don't skip past the first line if there is
line info. (m32r_virtual_frame_pointer): new function.
(m32r_fix_call_dummy): no return value needed.

* target.h: Add default definition of TARGET_VIRTUAL_FRAME_POINTER.
* ax-gdb.c (gen_frame_args_address, gen_frame_locals_address):
use TARGET_VIRTUAL_FRAME_POINTER to determine frame pointer.
(gen_trace_for_expr): new argument, address of tracepoint,
gets passed to new_agent_expr and added to struct agent_expr.
(is_nontrivial_conversion): call to new_agent_expr now requires
a dummy argument. (agent_command): use get_current_frame() to
get current PC scope; pass it to gen_trace_for_expr.

determine the virtual frame pointer, for collecting locals/args.
(add_local_symbols, collect_symbol): add a register/offset pair of
arguments so that the virtual frame pointer can be passed in.
Convert mn10300, MIPS and powerpc/rs6000 targets to use
BREAKPOINT_FROM_PC
Delete global variable memory_breakpoint_size. Use BREAKPOINT_FROM_PC
instead.
* symfile.c (deduce_language_from_filename): rewrite so as to
work from a table of filename extensions, modifiable by the user.
(filename_language_table): new data structure.
(set_ext_lang_command): new function for new command, "set

support functions for the above.
* language.c (language_enum): new function. Support for above.
* coffread.c (coff_symtab_read): Discard C_LABEL's that are not
function entry points, to avoid getting them in the stack dump
instead of the actual function.
without NAT_FILE definition, configure will assume that GDB cannot
run native.
* config/m68k/nm-delta68.h (KERNEL_U_SIZE): New macro.
* delta68-nat.c (kernel_u_size): New function.
* rdi-share/host.h: if compiling under Cygwin, make sure new
preprocessor define is defined. Define it if not.

* rdi-share/aclocal.m4: regenerate
* rdi-share/configure: regenerate

* gdbtk-cmds.c: Can't start using new API names yet. Switch
back
to calling cygwin32_ funcs until some time has passed...
* gdbtk.c: Ditto. Also, include sys/cygwin.h for Cygwin,
instead
of providing own proto.
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.

multithread debugging.
(remote_get_threadlist) : get a partial list of threads
(remote_threadlist_iterator) : Step through all the threads
(init_remote_threadtests) : Optional builtin unit test commands.
* thread.c (bind_target_thread_vector) : Implementa a more dynamic
way of accessing target specific thread info functions than
FIND_NEW_THREADS.
(target_thread_info) : Function to get extended thread information.
* gdbthread.h : Export internal data structures corresponding to
external detailed thread info response. This is more like a 'ps'
command than what might be expected of host based threads. This
is for embedded systems.
* console.tcl (complete): I added the ability to pass from_tty
from gdb_cmd to the underlying commands. Pass 1 when the
command is invoked from the console.
* interface.tcl (gdbtk_tcl_tstart, gdbtk_tcl_tstop): Run the
src window's do_tstop method rather than manipulating the
widgets by hand.
* src.tcl (build_win): Redo the packing so that the function
combobox doesn't push all the other combo-boxes off the screen
if it has a very long function name in it.
* srcbar.tcl (do_tstop): Added a mode that just changes the
GUI, which can be called from console hooks.
* srctextwin.tcl: Fixed some bugs I introduced in setting
breakpoints in the assembly & mixed mode windows. Dropped
the notion of joint breakpoint images for lines that have
breakpoints of two separate types. Too fragile.
Also added the "dont_change_appearance" flag, used in the
continue_to_here method to tell the GUI not to reflect the
temporary disabling of all the breakpoints.
* toolbar.tcl (insert_buttons): Added a little more error-checking.
Thu Nov 12 15:20:15 1998 Jim Ingham <jingham@cygnus.com>
* gdbtk-cmds.c (gdb_cmd): Added an optional second argument to the
gdb_cmd, which is from_tty. This is passed to the gdb command
parser. It is 0 by default, and the console window passes 1.
* gdbtk-cmds.c: moved disassemble_from_exec from gdbtk.c to gdbtk-cmds.c
with all the other link-var'ed variables
* gdbtk-hooks.c (gdbtk_trace_find): Only run the hook functions if
we are called from_tty.
* gdbtk-hooks.c (gdbtk_trace_start_stop): Set the trace buttons
from a trace_start_command callback rather than doing it as a
special case in gdb_cmd.
* tracepoint.c (tstart_command, tstop_command): Add call to
trace_start_stop_hook here.
Wed Nov 4 12:41:42 1998 Jim Ingham <jingham@cygnus.com>
* actiondlg.tcl: Get the stack collect string from an instance
variable. Need to implement some way to get this from the
target settings...
* global_pref.tcl (toggle_tracing_mode): Add & remove hooks
when you go in and out of tracing mode. Also reset the B1
behavior when you leave tracing mode
* interface.tcl (gdbtk_tcl_trace_find_hook): Added the trace
find hook, so you can switch the GUI state when the tfind
command is used to enter & leave browse mode.
* srcbar.tcl (constructor, destructor trace_find_hook): Added
the trace_find_hook to the source toolbar, and added the
necessary hooks to handle it.
* srctextwin.tcl (trace_find_hook): Added a trace find hook to
the sourcebar as well.
* stack.tcl (update): protect against errors in gdb_stack.
Just return "NO STACK" if we couldn't get it.
* src_pref.tcl (constructor, cancel): Put all the saved prefs
in an array, on cancel, see if any have changed and only
rebuild the window if there have been changes.
Mon Nov 2 13:24:10 1998 Jim Ingham <jingham@cygnus.com>
* bp.tcl (update): The hook function was passing more
arguments than this function expected.
Mon Nov 2 11:16:10 1998 Jim Ingham <jingham@cygnus.com>
* toolbar.tcl: Added Tdump image.
Fri Oct 30 17:36:05 1998 Jim Ingham <jingham@cygnus.com>
* src.tcl (set_execution_status): Changed status messages,
tracing is not the same as async debugging...
Fri Oct 30 17:06:31 1998 Jim Ingham <jingham@cygnus.com>
* bp.tcl (bp_all): Only remove tracepoints in the tracepoint
window, and breakpoints in the breakpoint window.
Fri Oct 30 11:22:23 1998 Jim Ingham <jingham@cygnus.com>
* actiondlg.tcl: Added special tag "Collect Stack". This
still needs to get hooked into the target database to deal
with targets that need to do something special to collect the
stack. Also moved some repeated code into loops.
* main.tcl (source_file): Source in a file of gdb commands.
* srcbar.tcl (constructor): Added source file menu entry, and
made stack buttons belong to both the Trace & Control classes.
* srctextwin.tcl (constructor): One too many separators in the
trace trace popup menu.
* tclIndex: regenerated.
* tfind_args.tcl: Added "tfind frame"
* toolbar.tcl (create_button): Allow a button to belong to
more than one class.
* toolbar.tcl (enable_ui): Eliminate redundant code, and allow
a button to belong to more than one class.
* toolbar.tcl (create_trace_menu): Added save tracepoints &
Tfind frame menu items.
* tracedlg.tcl: Added deletion of actions, and fixed a
the whiile-stepping combobox callback for the new combobox.
* util.tcl (save_trace_commands): new proc.
1998-10-29 Michael Snyder <msnyder@demo-laptop2.cygnus.com>
* target.tcl: add /dev/cua0 for Linux.
Tue Oct 27 13:46:03 1998 Jim Ingham <jingham@cygnus.com>
* Many little bug fixes all over in order to get tracing to work
along with normal program control.
* toolbar.tcl: Rewrote much of the code here to put commonly
used code into functions, and clean up adding menus and
buttons. Added the ability to disable particular menu items,
not just whole menus. Added the ability to delete and insert
buttons on the fly.
* srcbar.tcl: Pushed the changes to toolbar.tcl into this file.
* srctextwin.tcl: Changed the code dealing with breakpoints
and tracepoints to use the text tags more consistently. Use
only one set of menus for the whole widget, rather than having
a separate set for the SRC+ASM case. Rewrote a lot of the
code to separate out the tracing & program control functions.
* interface.tcl (gdbtk_tcl_breakpoint): pass more information
to the scrtextwin when a breakpoint changes state, so it can
do the right thing without having to guess...
* tracedlg.tcl (build_win): get the packing right so the
window expands correctly.
* main.tcl: do_tstop -> tstop, do_tstart -> tstart to avoid
confusion with the methods in ScrBar.tcl.
* prefs.tcl: Added two new preferences B1_Behavior to control
whether B1 sets breakpoints or tracepoints.
* src_prefs.tcl: Put in support for the B1_Behavior.
* global_prefs.tcl: Put back tracing checkbox.
* tdump.tcl: Fixed an incorrect (1 rather than 1.0) text
widget line specification.
* tfind_args.tcl (build_win): Bind return in the entry to the
OK button. Clear the entry field if the Type has changed.
* utils.tcl: Added comments for the debug commands.
* watch.tcl (build_win): Flash the OK button before invoking it.
Wed Nov 4 12:41:42 1998 Jim Ingham <jingham@cygnus.com>
* gdbtk-cmds.c (gdb_set_bp_addr): Pass the type, enable & thread
to gdbtk_tcl_breakpoint.
* gdbtk-hooks.c (gdbtk_trace_find): Added this function. It is
the hook function for tfind commands.
* tracepoint.c (trace_find_command): Added the trace_find_hook,
run when you do trace_find_command.
* tracepoint.h: Define the trace_find_hook.
Mon Nov 2 11:16:10 1998 Jim Ingham <jingham@cygnus.com>
* gdbtk-cmds (gdb_get_tracepoint_info): Demangle C++ function names.
Fri Oct 30 11:22:23 1998 Jim Ingham <jingham@cygnus.com>
* gdbtk-cmds (gdb_get_tracepoint_info): Fixed typo.
Wed Oct 28 10:14:33 1998 Jim Ingham <jingham@cygnus.com>
* gdbtk-cmds.c: Made the bdtypes & bpdisp arrays shared so they
could be used in gdbtk-hooks.c (breakpoint_notify).
Also fixed a few error messages to actually print the bp number
rather that #%d...
* gdbtk-hooks.c (breakpoint_notify): pass more of the information
about the breakpoint into the Tcl command, so it does not have to
try and guess about information we have on the C side.
* gdbtk.h: Export the bptypes & pbdisp arrays.
which define CRLF_SOURCE_FILES.
* win32-nat.c: 1) Add thread support, 2) fix ability to attach to
a running process, and 3) implement limited support for cygwin
signals.
(thread_rec): New function.
(child_add_thread): Ditto.
(child_init_thread_list): Ditto.
(child_delete_thread): Ditto.

operation.
(child_store_inferior_registers): Ditto.
(child_continue): Ditto.
(child_thread_alive): Ditto.
(cygwin_pid_to_str): Ditto.
(handle_load_dll): Reorganize, add first attempt at reading
dll names from attached processes. Change info messages to provide
more information when dll is already loaded.
(handle_exception): Changes mandated by new thread-aware structures.
(child_wait): Track thread creation/destruction. Handle cygwin
signals.
(child_create_inferior): Ditto.
(child_resume): Ditto.
(child_kill_inferior): Ditto. Close child process handle to avoid a
handle leak.
(child_ops): Fill out child_ops fields that deal with threads.
* config/i386/tm-cygwin32.h: Declare function and macro needed
for converting a cygwin "pid" to a string.
* config/i386/xm-cygwin32.h: define HAVE_SIGSETMASK as 0 since
sigsetmask is not defined in cygwin.
(ice_stepi): Use do_gdb to step properly.
(ice_nexti): Use do_gdb to step properly.
(view_source): Correct call to src window's location for new version.
[Support for trace debugging: registers that were not collected.]
* remote.c (remote_fetch_registers): accept 'xxxx' in the register
packet, with the meaning "register value is not available".
Set register_valid to -1, which will connote "no value available".
* findvar.c (read_relative_register_raw_bytes): return failure if
register_valid == -1. (value_of_register): return failure if
register_valid == -1. (read_var_value): return error if
value_of_register fails for a register variable.
(value_from_register): return failure if register_valid == -1.
* eval.c (evaluate_subexp_standard): return error if
value_of_register fails for a register used in an expression.
* infcmd.c (do_registers_info): display "value not available"
for registers for which register_valid == -1.
* tracepoint.c (set_raw_tracepoint): just save the filename as is
from the symbol table, rather than trying to prepend the dir name.
Also save the bfd section. (tracepoints_info): use the section
when looking up the function name.
* tracepoint.h: add section field to tracepoint struct.
* patch approved by shebs
Wed Oct 28 12:33:52 EST 1998 Frank Ch. Eigler <fche@cygnus.com>
* configure.in: Accept both -skyb- and -sky- for
--with-sim-funit/gpu2 options.
* configure: Rebuilt.
* configure.in (AM_EXEEXT): Use AC_EXEEXT instead.
* configure: Regenerated.
Geoff just removed the AM_EXEEXT definition from ../binutils/aclocal.m4
so we would have been hosed in the near future.
* command.c copying.c copying.awk core-aout.c core-regset.c
corelow.c dcache.c i386-tdep.c i386v4-nat.c i387-tdep.c

(make_pointer_type): Add braces to remove nested if-else ambiguity.
(make_reference_type): Ditto.

environment.
* symtab.c: Add prototypes.
(find_methods): Add braces to remove nested if-else ambiguity.
(search_symbols): Set 'i' to an initial value to suppress a
possibly-used-before-initialized warning.
* valops.c: Add prototypes.
(value_cast): Set 'eltype2' to an initial value to suppress a
possibly-used-before-initialized warning.
(value_of_variable): Add braces to remove nested if-else ambiguity.
(value_of_this): Ditto.
* valprint.c: Add prototypes.
(print_floating): Add braces to remove nested if-else ambiguity.
Looks like a big change, but it is really just a lot of small stuff.
In the cases where GCC was flagging a possible use-before-initialized
warning on variables, it turned out that these were being used properly
but GCC couldn't see that.
"wait.h" was defining all WIF* macro's instead of filling in those
that <wait.h> missed. Stops heaps of warnings from <wait.h>
re-defining WIF*s defined in "wait.h".
* defs.h: Move _initialize_printcmd, _initialize_stack,
_initialize_blockframe out of here and in to their respective .c files.
* blockframe.c: Move _initialize_blockframe prototype to here.
* printcmd.c: Move _initialize_printcmd prototype to here.
* stack.c: Move _initialize_stack prototype to here.
* source.c, symtab.h: Move _initialize_source prototype to the .c file.
* values.c, value.h: Move _initialize_values prototype to the .c file.
* gdbthread.h, thread.c: Move _initialize_thread prototype to the .c
file.
* breakpoint.c, breakpoint.h: Move _initialize_breakpoint prototype
to the .c file.
* abug-rom.c alpha-nat.c alpha-tdep.c annotate.c ax-gdb.c bcache.c:
Standardize comments for the prototype section of these files.
* configure.in: Look in libc for wctype before looking for it in libc.
The last one is to fix the GNU ld (~2.9.1) + Solaris 2.6 interaction problem
where an empty stub library (libw) causes a core dump when we call vasprintf
(e.g. `info br') in the final linked gdb.
version didn't work for sol2.6; pushed it to autoconf.
* configure.in (gdb_cv_proc_service_is_old): new test.
* acconfig.h (PROC_SERVICE_IS_OLD): new define.
* configure, config.in: regenerate.
* blockframe.c (find_pc_sect_partial_function): Add braces to avoid
possible nested-if confusion.
* breakpoint.c (breakpoint_here_p): Ditto.
(breakpoint_inserted_here_p): Ditto.
(breakpoint_thread_match): Ditto.
* gnu-regex.c: Define _REGEX_RE_COMP only if it isn't already defined.
* gnu-regex.h: Define _REGEX_RE_COMP to pick up old compatability
prototypes.
* symtab.h: Add prototype for _initialize_source.
* value.h: Add prototype for _initialize_value.

(make_cleanup): Add make_cleanup_func typedef and switch to using
a prototype for this function.
(mfree): Add prototypes for mmalloc, mrealloc, mfree if we aren't
using mmalloc.
* ax-gdb.c breakpoint.c coffread.c corelow.c dbxread.c dwarf2read.c
dwarfread.c elfread.c eval.c exec.c gdbtk-cmds.c gdbtk.c infcmd.c
infrun.c mipsread.c nlmread.c os9kread.c parse.c printcmd.c symfile.c
symmisc.c symtab.c thread.c top.c tracepoint.c typeprint.c valops.c:
Cast parameters passed to make_cleanup to use the new
make_cleanup_func typedef.
More warning cleanups. There are still a bunch of places where the first
argument to make_cleanup is not cast to (make_cleanup_func); these are
either due to the function fitting the make_cleanup_func specification
already (e.g. free()) or they are in files that weren't compiled when
I did my make on a Linux native system. Bwahahaha. You can see them
like this:
grep make_cleanup\ * | grep -v make_cleanup_func
I'll surely go back and clean up the remaining suspicious calls in
GDB one of these days. :-)
* configure.in: Check for sys/debugreg.h, asm/debugreg.h.
* i386v-nat.c: Include asm/debugreg.h, sys/debugreg.h if it is not
present.
This is to work around a conflict where the Linux 2.1.x kernel and glibc
2.0.x are not in sync; including <sys/debugreg.h> will result in an error.
With luck, these losers will get their act together and we can trash
this hack in the near future.
address range of a compilation unit without children.
* mdebugread.c (parse_partial_symbols): Fix handling of stabs
continuations, use xmalloc and xrealloc.
There should be sufficient information/hooks now to eliminate
this hack.
* exec.c (file_command): Add a new hook here to inform ui's
when the exec file has changed. Adding it here allows the
ui to be informed after symbol reading.
* gdbcore.h: Add declaration of file_changed_hook.
* stabsread.c (rs6000_builtin_type): Create a complex float instead
of an error.
(read_sun_floating_type): Similarly.
(read_range_type): Create a complex float if self_subrange is
true.
* gdbtk-cmds.c (gdb_set_bp_addr): New command. Sets a
breakpoint at an address. Use this instead of gdb_cmd "break"
because the syntax of the break command is broken and doesn't
allow you to create a thread-specific BP at an address. Also
this is faster.
* gdbtk-cmds.c (gdb_set_bp): Add an optional thread number.
(gdb_find_bp_at_line): New function. Returns a list of bpnums
at the specified line number.
(gdb_find_bp_at_addr): New function. Returns a list of bpnums
at an address..
