than $(READLINE_SRC) so #include <readline/readline.h> will work.
* top.c: #include <readline/history.h> instead of "history.h".
* tracepoint.c: Likewise.
* mac-xdep.c: Likewise.
* tracepoint.c: Move default definition of
TARGET_VIRTUAL_FRAME_POINTER from here to target.h.
* 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.

tracepoint; store it in new field of struct agent_expr.
* ax.h (struct agent_expr): add new field for tracepoint address.

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.
* 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.
[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.
* 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.
* defs.h: Include sys/types.h or stddef.h to get size_t.
(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. :-)
* tracepoint.c (remote_set_transparent_ranges): new function.
Send the start and end addresses of all loadable read-only
sections down to the trace target, so that it can treat them
as "transparent" (ie. don't care if they were collected or not).
* tracepoint.c (encode_actions): Treat register names and simple
variable names as special cases and don't convert them to byte-
codes: these things can be collected far more efficiently
without invoking the bytecode interpreter.
* gdbtk.c: (gdb_trace_status) new function.
(gdbtk_init) added command "gdb_is_tracing".
(tracepoint_notify) added passcount information.
* tracepoint.c (trace_status_command): Recognize a boolean return
value from the stub to indicate whether trace experiment is
running. Export this value as a global state variable
(trace_running_p) for use by the GUI. (from Michael Snyder)
(trace_pass_command) added call to modify_tracepoint_hook.
* tracepoint.h export trace_running_p
* config/m68k/xm-sun3os4.h: Remove malloc declarations, they
are handled via autoconf now.
* remote.c (remote_ops, extended_remote_ops): Replace static
forward declaration by moving the static definition to the top of
the file, for old K&R compilers.
* tracepoint.c (collect_symbol, trace_start_command):
Replace ANSI string concatenation with K&R compatible simple string.
if it exists.
Remove static declaration of free_actions.
* tracepoint.h: Add declaration of free_actions.
* gdbtk.c (gdbtk_modify_tracepoint): Define new tracepoint modification
hook.
(gdbtk_print_frame_info): Define this hook so that current_source_symtab
is set properly.
(gdb_actions_command): Use free_actions () from tracepoint.c/h.
* tracepoint.c (tracepoint_operation): call free_actions instead
of free. (free_actions): eliminate some memory leaks for actions.
(validate_actionline): pass string arg by reference, so we can
change the pointer. Change all memrange collection arguments to
canonical form (literal address and size), to enforce early
evaluation. Accept UNOP_MEMVAL (assembly variables) for
trace collection. (parse_and_eval_memrange): accept expressions
for the address and size fields of a memrange (and evaluate
them immediately). (several places): use -1 instead of zero
to distinguish an absolute memrange from a register-relative one.
(encode_actions): add handling for UNOP_MEMVAL (assembly variable).
* tracepoint.c (finish_tfind_command): improved algorithm for
deciding when we've "stepped" into a new stack frame.
(map_args_over_tracepoints): loop over tracepoint list "safely",
since list elements may be deleted during loop.
(read_actions): add actions to history list.
* tracepoint.c (finish_tfind_command): call do_display so that
auto-displays are updated by tfind. Also, keep track of frame
and current-function so that tfind behaves like stepping (only
show the stack frame if we step into a new function or return).
