        a prototype for this function.

        dwarfread.c elfread.c eval.c exec.c gdbtk-cmds.c gdbtk.c infcmd.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. :-)

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.
1994-10-08 03:41:21 +00:00

	(command_line_input): Print annotatation before and after prompt.
	* blockframe.c (flush_cached_frames): Print annotation.

	change output format.
	* breakpoint.c: Print annotation whenever a breakpoint changes.

	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.

	* stabsread.c, stabsread.h (define_symbol):  Change valu parameter
	to a CORE_ADDR.
	* stabsread.c (read_range_type):  Handle the case where the lower
	bound overflows and the upper doesn't and the range is legal.
	* infrun.c (resume):  Do not step a breakpoint instruction if
	CANNOT_STEP_BREAKPOINT is defined.

	* inferior.h (CALL_DUMMY_LOCATION):  New variant AT_ENTRY_POINT.
	Now that we have the bp_call_dummy breakpoint the call dummy code
	is no longer needed. PUSH_DUMMY_FRAME, PUSH_ARGUMENTS and
	FIX_CALL_DUMMY can be used to set up everything for the dummy.
	The breakpoint for the dummy is set at the entry point and thats it.
	* blockframe.c (inside_entry_file, inside_entry_func):  Do not stop
	backtraces if pc is in the call dummy at the entry point.
	* infcmd.c (run_stack_dummy):  Handle AT_ENTRY_POINT case. Use
	the expected breakpoint pc when setting up the frame for
	set_momentary_breakpoint.
	* symfile.c (entry_point_address):  New function for AT_ENTRY_POINT
	support.
	* valops.c (call_function_by_hand):  Handle AT_ENTRY_POINT case.

2289e1c30b * inflow.c (generic_mourn_inferior): Call reinit_frame_cache
instead	of doing it ourself.
	* blockframe.c (reinit_frame_cache): Use code which was in
	generic_mourn_inferior so we can use this function even when
	we have switched targets.
	* corelow.c (core_detach): Call reinit_frame_cache.
	* target.c (target_detach): Don't call generic_mourn_inferior
	(revert yesterday's change, now handled by core_detach).
	* objfiles.c (free_objfile): Detach any core file if we call
	SOLIB_CLEAR.  #include target.h.

479fdd26ee * blockframe.c (block_innermost_frame): Uncomment.
Return NULL if passed NULL.
	* frame.h: Declare it.
	* expression.h (union exp_element): Add field block.
	* parse.c (write_exp_elt_block): New function.
	* expression.h (OP_VAR_VALUE): Now takes additional struct block *.
	* *-exp.y: Write block for OP_VAR_VALUE.
	* eval.c, expprint.c, parse.c: Deal with block for OP_VAR_VALUE.
	* valops.c, value.h (value_of_variable), callers:
	Add second argument, for block.

Peter Schauer
d541211d61 * blockframe.c, frame.h (sigtramp_saved_pc): New routine to fetch
the saved pc from sigcontext on the stack for BSD signal handling.
	* config/i386/tm-i386bsd.h (SIGTRAMP_START, SIGTRAMP_END, FRAME_CHAIN,
	FRAMELESS_FUNCTION_INVOCATION, FRAME_SAVED_PC, SIGCONTEXT_PC_OFFSET):
	Define to make backtracing through sigtramp work.
	* config/vax/tm-vax.h (SIGTRAMP_START, SIGTRAMP_END, TARGET_UPAGES,
	FRAME_SAVED_PC, SIGCONTEXT_PC_OFFSET):  Ditto.

23a8e2915c * frame.h, blockframe.c, stack.c, a29k-tdep.c,
config/gould/tmp-{pn,np1}.h,
	config/{sparc/tm-sparc.h,pyr/tm-pyr.h,vax/tm-vax.h}: Remove field
	next_frame from struct frame_info.  It has no purpose beyond
	->next->frame and is an artifact from GDB 2.8.

e140f1dab1 Remove tdesc stuff. Remove FRAME_CHAIN_COMBINE from all tm-*.h files,
since it was always defined exactly the same in all of them.

John Gilmore
5259796be2 * blockframe.c (frameless_look_for_prologue): Speed up by
calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
        * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
        Define two variants, one faster.
        * sparc-tdep.c (sparc_frame_chain):  Use target_read_memory
        and return zero, rather than giving an error.
        (setup_arbitrary_frame):  Initialize the PC in the new frame.
        (skip_prologue):  Add a second arg saying whether we're just
        checking for a frameless function or not.
