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. :-)

16726dd15b The point of these changes is to avoid reading the frame pointer
and stack pointer during stepping, to speed things up.
	A.  Changes to not select a frame until we need a selected frame:
	    * blockframe.c (flush_cached_frames): Call select_frame (NULL, -1).
	    * infrun.c (wait_for_inferior): Move call to select_frame back to
	    normal_stop.  This reverts a change of 13 Apr 94 (it says Jeff
	    Law, but the change was my idea); the only reason for that change
	    was so we could save and restore the selected frame in
	    wait_for_inferior, and now that flush_cached frames clears the
	    selected frame, that should work OK now.
	B.  Changes to not create a current_frame until we need one:
	    * blockframe.c (get_current_frame): If current_frame is NULL, try
	    to create an innermost frame.
	    * sparc-tdep.c (sparc_pop_frame), infcmd.c (run-stack_dummy),
	    infrun.c (wait_for_inferior), thread.c (thread_switch),
	    convex-tdep.c (set_thread_command), a29k-tdep.c (pop_frame),
	    alpha-tdep.c (alpha_pop_frame), convex-xdep.c (core_file_command),
	    h8300-tdep.c (h8300_pop_frame), h8500-tdep.c (h8300_pop_frame),
	    hppa-tdep.c (hppa_pop_frame), i386-tdep.c (i386_pop_frame),
	    i960-tdep.c (pop_frame), m68k-tdep.c
	    (m68k_pop_frame), mips-tdep.c (mips_pop_frame), rs6000-tdep.c
	    (push_dummy_frame, pop_dummy_frame, pop_frame), sh-tdep.c
	    (pop_frame), config/arm/tm-arm.h (POP_FRAME),
	    config/convex/tm-convex.h (POP_FRAME), config/gould/tm-pn.h
	    (POP_FRAME), config/ns32k/tm-merlin.h (POP_FRAME),
	    config/ns32k/tm-umax.h (POP_FRAME), config/tahoe/tm-tahoe.h
	    (POP_FRAME), config/vax/tm-vax.h (POP_FRAME): Don't
	    call create_new_frame.
	    * corelow.c (core_open), altos-xdep.c (core_file_command),
	    arm-xdep.c (core_file_command), gould-xdep.c (core_file_command),
	    m3-nat.c (select_thread), sun386-nat.c (core_file_command),
	    umax-xdep.c (core_file_command): Don't call create_new_frame; do
	    call flush_cached_frames.
	    * blockframe.c (reinit_frame_cache): Don't call create_new_frame
	    or select_frame.
	C.  Changes to get rid of stop_frame_address and instead only
	fetch the frame pointer when we need it.
	    * breakpoint.c (bpstat_stop_status): Remove argument
	    frame_address; use FRAME_FP (get_current_frame ()).
	    * infrun.c (wait_for_inferior): Don't pass frame pointer to
	    bpstat_stop_status.
	    * infrun.c (wait_for_inferior): Use FRAME_FP (get_current_frame
	    ()) instead of stop_frame_address.
	    * infrun.c (save_inferior_status, restore_inferior_status),
	    inferior.h (struct inferior_status): Don't save and restore
	    stop_frame_address.
	    * inferior.h, infcmd.c, thread.c (thread_switch), m3-nat.c
	    (select_thread): Remove stop_frame_address and uses thereof.
	D.  Same thing for the stack pointer.
	    * infrun.c (wait_for_inferior): Remove stop_sp and replace
	    uses thereof with read_sp ().
	E.  Change to eliminate one nasty little spot where we were
	wanting to know the frame pointer from before the current step
	(idea from GDB 3.5, which saved my ass, because my other ideas of
	how to fix it were very baroque).
	    * infrun.c: Remove prev_frame_address.
	    * infrun.c (wait_for_inferior, step_over_function): Use
	    step_frame_address instead of prev_frame_address.
	F.  Same basic idea for the stack pointer.
	    * inferior.h, infcmd.c: New variable step_sp.
	    * infcmd.c (step_1, until_next_command): Set it.
	    * infrun.c: Remove prev_sp and replace uses by step_sp.
	    * infrun.c (wait_for_inferior): If we get out of the step
	    range, then set step_sp to the current stack pointer before we
	    start going again.

6c803036a9 * main.c (main): Accept --annotate=N option and make --fullname
the same as --annotate=1.
	(command_line_input): Print annotatation before and after prompt.
	* blockframe.c (flush_cached_frames): Print annotation.
	* Rename frame_file_full_name to annotation_level and move it from
	symtab.h to defs.h.
	* source.c (identify_source_line): If annotation_level > 1,
	change output format.
	* breakpoint.c: Print annotation whenever a breakpoint changes.
	* main.c: New variable server_command.
	(command_line_input): Parse "server " and set server_command.
	(dont_repeat): Check server_command.

999dd04b89 * breakpoint.h (enum bptype): Add bp_hardware_watchpoint and
bp_watchpoint_scope breakpoints.
	(struct breakpoint): Add val_chain and related_breakpoint fields
	for use by watchpoints.

	* breakpoint.c (within_scope): Delete.  No longer used.
	(TARGET_CAN_USE_HARDWARE_WATCHPOINT): Provide default definition.
	(target_{remove,insert}_watchpoint): Likewise.
	(can_use_hardware_watchpoint): New function.
	(remove_breakpoint): New function to remove a single breakpoint
	or hardware watchpoint.
	(insert_breakpoints): Handle insertion of hardware watchpoints.
	Store a copy of the value chain derived from the watchpoint
	expression.
	(remove_breakpoints): Simplify by using remove_breakpoint.
	(delete_breakpoint): Likewise.
	(watchpoint_check): Delete the watchpoint and watchpoint scope
	breakpoints when the watchpoint goes out of scope.  Save & restore
	the current frame after checking watchpoints.
	(breakpoint_init_inferior): Likewise (restarting the program
	makes all local watchpoints go out of scope).
	(bpstat_stop_status): Handle hardware watchpoints much like normal
	watchpoints. Delete the watchpoint and watchpoint scope breakpoint
	when the watchpoint goes out of scope.  Remove and reinsert all
	breakpoints before returning if we stopped when a hardware watchpoint
	fired.
	(watch_command): Use a hardware watchpoint when possible.  If
	watching a local expression, build a scope breakpoint too.
	(map_breakpoint_numbers): Also call given function for any
	related breakpoints.
	(disable_breakpoint): Never disable a scope breakpoint.
	(enable_breakpoint): Handle hardware breakpoints much like normal
	breakpoints, but recompute the watchpoint_scope breakpoint's
	frame and address  (if we have an associated scope breakpoint).
	(read_memory_nobpt): Handle hardware watchpoints like normal
	watchpoints.  When necessary handle watchpoint_scope breakpoints.
	(print_it_normal, bpstat_what, breakpoint_1, mention): Likewise.
	(clear_command, breakpoint_re_set_one, enable_command): Likewise.
	(disable_command): Likewise.

	* blockframe.c (find_frame_addr_in_frame_chain): New function.
	Extern prototype added to frame.h

	* infrun.c (wait_for_inferior): Set current_frame and select
	a frame before checking if we stopped due to a hardare watchpoint
	firing.  Handle stepping over hardware watchpoints.
	(normal_stop): Remove unnecessary call to select_frame.

	* value.h (value_release_to_mark): Declare.
	* values.c (value_release_to_mark): New function.

	* procfs.c (procfs_wait): Add cases for hardware watchpoints.
	(procfs_set_watchpoint, procfs_stopped_by_watchpoint): New functions.

	* hppab-nat.c (hppa_set_watchpoint): New function.

	* config/pa/nm-hppab.h (STOPPED_BY_WATCHPOINT): Define.
	(HAVE_STEPPABLE_WATCHPOINT): Define.
	(TARGET_CAN_USE_HARDWARE_WATCHPOINT): Define.
	(target_{insert,delete}_watchpoint): Define.
