fa3764e2bf * From Peter Schauer.
* breakpoint.c (breakpoint_re_set_one):  Keep temporary
        breakpoints bp_until, bp_finish, bp_watchpoint_cope, bp_call_dummy
        and bp_step_resume in case breakpoint_re_set_one is called due
        to a step over a dlopen call.
        * infrun.c (wait_for_inferior):  Always remove breakpoints from
        inferior in BPSTAT_WHAT_CHECK_SHLIBS case.

0fe1522ad0 * breakpoint.c (remove_breakpoint): Change error to warning so
that hardware watchpoint removal problems won't leave breakpoint
	traps in the target.
	* configure configure.in:  Make --enable-gdbtk be the default.
	* remote-e7000.c (e7000_insert_breakpoint,
	e7000_remove_breakpoint):  Use e7000 based breakpoints, not memory
	breakpoints.
	* (e7000_wait):  Adjust PC back by two when we see a breakpoint to
	compensate for e7000 maladjustment.
	* sparcl-tdep.c (sparclite_check_watch_resources):  Fix logic bug
	which prevented hardware watchpoints from working.

cd10c7e388 * breakpoint.c (breakpoint_re_set): #ifdef GET_LONGJMP_TARGET
around calls to create_longjmp_breakpoint.  Why install the
	breakpoints if we can't find the longjmp target?
	* infrun.c (wait_for_inferior):  Cleanup comments near call test.
	* remote-mips.c:  Fixed a bunch of prototypes to avoid char/int
	complaint from picky compilers.  Add comment to mips_expect.
	Replace all instances of sr_get_debug with remote_debug.
	* (mips_readchar):  Don't jam init string to monitor.
	mips_initialize() handles that.
	* (mips_receive_header):  Print better message when we get too
	much garbage.
	* (mips_request):  Allow caller to pass in buff to allow them to
	analyze the returned message.
	* (mips_initialize):  Re-do initialization to try sending a BREAK,
	a ^C, and then a download escape sequence.  Cleanup protocol
	startup.  Eliminate sleeps.  Clear breakpoints (if using monitor
	breakpoints).  Re-init frame.
	* (mips_detach):  Close down target.
start-sanitize-gm
	* (mips_resume):  Pass signal down to target.
	* (mips_create_inferior):  Start target with TARGET_SIGNAL_PWR.
end-sanitize-gm
	* (mips_wait):  Handle return status with registers, or breakpoint stuff.
	* (mips_kill):  Add ^C handling.
	* (mips_insert_breakpoint mips_remove_breakpoint):  Call new
	breakpoint stuff if enabled.
	* (calculate_mask remote_mips_set_watchpoint
	remote_mips_remove_watchpoint remote_mips_stopped_by_watchpoint):
	Hardware watchpoint/breakpoint stuff.
	* (common_breakpoint):  Common code for new monitor breakpoint commands.
	* (mips_load):  Don't use `prompt'.  It's a global variable.
	* top.c (dont_repeat_command):  New command for use in
	user-defined commands to suppress auto-repeat (by hittin return key).
start-sanitize-gm
	* utils.c (request_quit):  Call target_kill here.  Good idea.
	Needs a better implementation.
end-sanitize-gm
	* valops.c:  Add start of auto function-call abandonment capability.

start-sanitize-gm
	* c-exp.y:  Add code (currently disabled) to handle GM dynamic
	structures (it conflicts with @!).
	* eval.c (evaluate_subexp_standard):  ditto.
	* expprint.c (print_subexp dump_expression):  ditto.
	* expression.h (enum exp_opcode):  ditto.
	* parse.c (length_of_subexp):  ditto.
	* configure, configure.in:  Add mip*-*-magic* target.
	* magic.c magic.h:  Special routines to handle GM stuff (like
	stepping through dispatcher).

706dc3ce33 * breakpoint.c (watchpoint_check): Don't bother restoring the
"selected" frame anymore, it's not necessary.  Initialize the
	frame cache before trying to find the current frame in the frame
	chain.

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.

	which performs one (the check_sigtramp2 one) of the functions
	which had been handled by the step_resume_breakpoint.  For each
	use of the step_resume_breakpoint, make it still use the

	* expprint (dump_expression), gdbtypes.h: Use it.
	* breakpoint.c (describe_other_breakpoints),
	symmisc.c (dump_symtab, print_symbol):
	Use filtered not unfiltered I/O.
	(remove_breakpoints): Remove BREAKPOINT_DEBUG code.  Might as well
	just run gdb under a debugger for this (and it had problems with
	printing addresses, how to print b->shadow, etc.).
	* buildsym.c (make_blockvector), core.c (memory_error),
	exec.c (print_section_info), maint.c (print_section_table),

step_resume_breakpoint for IN_SIGTRAMP cases.

	breakpoint.c (bpstat_what): Move step_resume from its own field of
	the struct bpstat_what into the main_action.  Make it override
	other breakpoints.  This is a conservative change in the sense
	that before the step resume breakpoint was a breakpoint.c
	breakpoint, hitting the step resume breakpoint overrode even
	calling bpstat_stop_status.

199b2450f6 Change the stream argument to _filtered to GDB_FILE *.
Change all references to stdout/stderr to gdb_stdout/gdb_stderr.

Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')

Replaced calls to fopen for output to gdb_fopen.

Added sufficient goo to utils.c and defs.h to make the above work.

The net effect is that stdio output functions are only directly used
in utils.c.  Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.

In the near future, GDB_FILE will stop being equivalant to FILE.

The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior.  The testsuite doesn't notice anything
like this, though.

Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code.  All output from commands
should go to a GDB_FILE.

Target-specific code can still use stdio directly to communicate with
targets.

	remote-es.c (es1800_load), comments in exec.c and corelow.c:

	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.

	  (bug_open): corrected typo, sr_multi_scan -> gr_multi_scan.
	  (bug_fetch_register): special case sfip register for m88110.
	  remove flag bit masking of pc registers.  This should be handled
	  by the ADDR_BITS_* macros.

	  Corrected sprint format for extended registers.
