9ed8604f38 * top.c (line_completion_function): Renamed from
symbol_completion_function, takes the line buffer and the
	point in the line buffer as additional arguments.
	(readline_line_completion_function):  New function, interface
	between readline and line_completion_function.
	(init_main):  Use it.
	(complete_command):  Use line_completion_function instead of

	them.
	* symtab.c (completion_list_add_name):  Recheck for duplicates
	if we intend to add a modified symbol.

	* gdbtypes.h (cplus_struct_type):  nfn_fields_total no longer
	includes the number of methods from the baseclasses.
	* stabsread.c (attach_fn_fields_to_type):  No longer add the
	number of methods from the baseclasses to TYPE_NFN_FIELDS_TOTAL,
	the baseclass type might not have been completely filled in yet.

	the total number of methods for a type, including the methods
	from baseclasses.
	(decode_line_1):  Use it instead of TYPE_NFN_FIELDS_TOTAL to

07aa9fdc6b * eval.c (evaluate_subexp): Make fnptr a LONGEST instead
of using longest_to_int.

	* infcmd.c (run_stack_dummy):  Reinstate set_current_frame call,
	mips and alpha targets need the real breakpoint pc for
	creating the breakpoint frame.

	* stack.c (return_command):  Cast return value to the return
	type of the function from which we return.
	* values.c (set_return_value):  Pass VALUE_CONTENTS unmodified

	when performing integral evaluations, implement BINOP_EQUAL and
	BINOP_LESS.

	comparison if both operands have TYPE_CODE_INT.

	* rs6000-tdep.c (pop_frame):  Make sure all registers are valid,
	as they are written back later. Handle sp restore for frameless
	functions. Use fdata.nosavedpc instead of fdata.frameless to
	determine if the pc has been saved.
	(function_frame_info):  Handle `mr r31,r1', which is generated by
	gcc-2.6, as a synonym for `oril r31,r1,0'.
	(skip_trampoline_code):  Handle shared library trampolines.
	* xcoffread.c (read_xcoff_symtabs):  Record XMC_GL symbols with
	their real name. Enables setting of breakpoints in shared libraries

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.

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.

* tm-rs6000.h (BELIEVE_PCC_PROMOTION): Define, since AIX cc gets
	it right.
	(aix_framedata): added nosavedpc field.
	(SAVED_PC_AFTER_CALL): Don't try to optimize; just call
	read_register.
	(FRAMELESS_FUNCTION_INVOCATION): Pass second argument of 0.
	(FRAME_SAVED_PC): If PC not saved, use SAVED_PC_AFTER_CALL.
	* rs6000-tdep.c (skip_prologue): Handle gcc generated stfd
	instructions as function_frame_info does.  Expand special case of
	st r31,-4(r1) to be st r31,NUM(r1), since gcc can generate offsets
	other than -4.
	(pop_frame): Add 4 rather than sizeof (int) to avoid host
	dependence.
	(function_frame_info): Set frameless if the function has no frame,
	and set nosavedpc if the PC was not saved.  Handle gcc generated
	stfd 31,-4(31); st 31, -12(31) correctly.
	(frameless_function_invocation): New second argument pcsaved; if 0
	return whether the function has a frame, if 1 return whether the
	function saved PC.
	(frame_initial_stack_address): Correct typo: cache registers for
	callee_fi, not for fi, (avoids reading garbage memory locations).

997cc2c0a3 Preliminary cleanup for splitting host/native/target.
* infptrace.c (child_resume):  Don't deal with NO_SINGLE_STEP
here; it is dealt with at a gdb-target-independent level.
* rs6000-tdep.c (single_step):  Don't call ptrace, we are a
high toned routine.  Fix return type to void.

* All GDB files that #include defs.h: Removed stdio.h.
	(defs.h): #include stdio.h.

This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion.  (n.b.
many configurations don't build for other reasons.)
