+Sat Mar 23 10:02:21 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	Cleanup for release 3.94.2:
+
+	* Makefile.dist: Pull REMOTE_OBS.  Fix saber includes for BFD
+	include files.  Roll version to 3.94.2.
+	
+	* coffread.c (init_stringtab):  Read length into unsigned char
+	array before swapping; don't assume 32-bit longs.
+
+	* target.c (target_info): Don't bother with get_sym_file, just use
+	the symfile global variable.
+	* symtab.h, symfile.c (get_sym_file):  Delete it.
+
+	* dbxread.c (dbx_symfile_init):  Don't depend on long == 4 bytes.
+	(define_symbol):  Set symbol line number to 0 if not gcc-compiled.
+	(read_type):  Replace one more error() with complain().
+
+	* mipsread.c (parse_partial_symbols):  Replace printf with complain.
+
+	* i960-tdep.c:  Fix copyright attribution.
+
+	* config.gdb:  Quote all backquotes in doublequotes.  You can
+	quote me on that.  BSD 4.4 shell found this one.
+
+	* infptrace.c (throughout):  The third argument to ptrace is an
+	int *, not an int.
+
+	* infrun.c (wait_for_inferior):  When program has terminated, we
+	have to call target_terminal_ours before we pop that target off
+	the stack (e.g. before a call to target_kill or
+	target_mourn_inferior).  This fixes problem where a program
+	terminates, then GDB stops for (tty output) and you have to type
+	"fg" to the shell to resume it.  FIXME:  This code for what to
+	do after termination really should be in normal_stop instead.
+
+	* gdbcore.h (read_memory_check):  Change declaration; it changed
+	names months ago.
+
+	* terminal.h:  Include <sgtty.h> before <sys/ioctl.h>, since in BSD
+	4.4 prereleases, this avoids a bug in their sgtty compatability
+	support.
+	* remote.c:  Use terminal.h rather than hand-rolling the same.
+
+	* signame.c, signame.h (psignal):  Arg is unsigned, not int.
+	* utils.c (strsave, strstr):  Fix arg types.
+	* valprint.c (val_print):  lint
+
+	MIPS symbol table support from Per Bothner:
+
+	* symfile.c (symtab_fns):  Remove initializer table that needs to
+	be hacked for each new symbol file format supported.
+	(add_symtab_fns):  New function, chains symbol table
+	handlers into the global list.
+	(symfile_init):  Search this list.
+	* symfile.h:  Add next pointer, declare add_symtab_fns.
+	* coffread.c (_initialize_coffread): Call add_symtab_fns.
+	* dbxread.c (_initialize_dbxread):  Call add_symtab_fns.
+
+	* mipsread.c (psymtab_to_symtab_1): return void instead of (struct
+	symbol *).  Thus, we no longer need the hack to trash
+	pst->filename.  Good, since that hack confused code in symfile.c!
+
+	(reorder_symtabs, destroy_all_symtabs):  Removed static
+	all_symtabs, which was used to qsort symtabs in reorder_symtabs.
+	Instead, the latter now uses a temporary array (stack-allocated
+	from an obstack, and then freed).
+
+	(parse_symbol):  Added a hack to fix up BLOCK_{START,END} if they
+	haven't been set in the outermost stBlock of a procedure. This was
+	a problem with f77 binaries on Ultrix 4.?.
+
+	(new_symtab, new_symbol, new_type):  Continue changing code to use
+	obstacks more and otherwise conform to dbxread internal style.
+	Made the free_code of symtabs be free_linetable (as in dbxread)
+	instead of free_contents.  This implies memory leaks when reading
+	a new symbol table, until the conversion is finished. Did change
+	(struct symbol) and (struct type) to be allocated on the
+	symbol_obstack.  Blocks and blockvectors are among the things
+	still "leaking."
+
+	* mipsread.c (parse_partial_symbols, parse_fdr):  It hasn't been
+	tested much, but it solved one problem (reported by Meissner), and
+	cleans up some other things.  The problem happened when an
+	included file contains actual code (functions) and not just
+	definitions. The mips coff is a little inconvenient there, since
+	it may cause a procedure to be mapped to the wrong psymtab.
+
+	* mips-tdep.c (heuristic_proc_desc):  Minor cleanup.
+	* mips-xdep.c (fetch_core_registers):  Minor cleanup.  FIXME,
+	this will need work for the new core paradigm.
+
+	Opcode patches from the net:
+
+	* mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
+	ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
+	missing altogether - they are added here.  From Bruce Bauman.
+	* mips-opcode.h:  The low mask for C0 instructions was too small.
+	From Garrett Lau.  I modified the fix to check the entire 32-bit
+	opcode.
+
+	* ns32k-opcode.h:  Fix opcodes for deiw and deid.  From Bruce
+	Bauman.
+
+Thu Mar 21 12:56:46 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
+
+	* dbxread.c (read_type): Pointer subtraction (value_sub in
+	valarith.c) sometimes failed because the types of the
+	 pointers being subtracted were not identical.
+	These differed because dbxread.c was allocating pointer types
+	using dbx_alloc_type+smash_to_pointer_type instead of
+	lookup_pointer_type. I failed to find a justification for the
+	former, so I changed it to use the latter. Similarly, I
+	replaced smash_to_function_type by lookup_function_type,
+	and smash_to_reference_type by lookup_reference_type.
+
+	* mipsread.c (parse_symbol, upgrade_type, parse_procedure, 
+	_initialize_mipsread):  corresponding changes.
+
+	* symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
+
+	* source.c (mod_path): Do tilde_expand on each component of the path,
+	rather than on the (list of) paths as a whole.
+	(print_source_lines):  Set first_line_listed in addition to
+	current_source_symtab and current_source_line.  If the source was
+	not findable, after a "dir" command to fix the problem,
+	a "list" would get the wrong lines.
+
+	While I was there... (gnu):
+
+	* dbxread.c (read_type):  Change error to complaint.
+
+Thu Mar 21 12:56:46 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	First attempt at detailed understanding of symbol table memory alloc.
+
+	* dbxread.c (dbx_symfile_read):  Free our string table if we
+	aren't the mainline.  Free the "info" struct since we're done with
+	it. 
+	(init_psymbol_list):  Free any previously allocated psymbol lists.
+	(): FIXME: Should realloc-down the psymbol lists when done reading
+	the main symbol file?
+
+	* symmisc.c (free_symtab):  Free fullname field too.
+
+	* xm-hp300hpux.h (USG):  #undef then #define so Makefile can -D.
+	(REGISTER_ADDR):  Make result type unsigned int.
+
+	* xconfig/{i386*,hp300hpux,altosgas,altos}:  All config files that
+	define REGEX must also define REGEX1 (its dependency).
+
+Tue Mar 19 21:28:57 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	* tconfig/i960:  No longer works, points you at vxworks960 or
+	nindy960.

+	print_address_symbolic.
+	(clear_breakpoints):  Remove unused function.
+	(breakpoint_re_set_one):  Guts of breakpoint_re_set.
+	(breakpoint_re_set):  Use catch_errors to do them all anyway.
+
+	* gdb-int.texinfo (Host versus Target):  Add section on what is
+	a "host" feature versus what is a "target" feature.
+
+	* infcmd.c (path_command, path_info):  Handle the PATH variable
+	(object search path) as conveniently as the source search path.
+	* environ.c (set_in_environ):  Set some vars in GDB's environment,
+	in addition to the child's.  PATH, G960BASE, G960BIN for starters.
+	* source.c (mod_path):  New function, from guts of
+	directory_command, modifies a path.  Used by path_command.
+	(directory_command):  Call it.

+
+	* utils.c (sevenbit_strings):  Add new printing option.
+	(printchar):  Use it.
+	(strsave):  Provide this handy helper routine.
+	(set_width_command):  Rename set_screen_width_command.
+	(_initialize_utils):  "set screen-width" => "set width";
+	"set screen-height" => "set height"; add sevenbit-strings.
+
+	* infcmd.c (do_registers_info):  Print floating point registers
+	in raw hex as well as float format, regardless of whether it is
+	a "virtual" convertible register.
+	* tm-sparc.h (PRINT_REGISTER_HOOK):  Print every pair of float
+	regs as a double, just in case it's being used that way.	
+	* values.c (unpack_long):  Comment on array/function coercion.
+	(unpack_double):  Argument is in target byte order now.  For
+	integer arguments, just call unpack_long and float the result.
+	* m68k-tdep.c: include defs.h for "const" handling.
+	* remote-nindy.c:  Use ieee-float stuff.
+	(nindy_fetch_registers):  Unpack double regs to host double, then
+	to extended.
+	(nindy_store_registers):  Pack extendeds to host double, flip
+	around by misusing unpack_double, send as target double.
+
+	* tm-vxworks68.h (FRAME_CHAIN):  Handle current frame pointer of
+	zero, as when stopped at the first instruction of a process.
+
+	* blockframe.c:  Fix filename in comment (param.h => tm.h).
+	* sparc-tdep.c (skip_prologue):  More explicit nudging comments.
+	* tm-68k.h:  Fix typos.
+
+Fri Mar 15 01:09:34 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	Changes from a bringup on the DEC Vax under Ultrix 4.0.
+
+	* coredep.c (fetch_core_registers):  Pass end-address of register
+	section to register_addr as expected.  Don't call supply_register
+	if we'd just pass it garbage.
+
+	* dbxread.c (read_dbx_symtab):  Skip N_NSYMS on Ultrix.
+
+	* exec.c (xfer_memory):  Use boolean xfer_fn result, not int.

+	* m68k-tdep.c:  Define ext_format_68881.
+	* sparc-tdep.c:  Define ext_format_sparc, though unused.
+	* Makefile.dist (HFILES):  Add ieee-float.h.
+	* inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
+	macros.
+

+	* dbxread.c:  Remove static symfile_bfd.
+	* infcmd.c (do_registers_info):  Add PRINT_REGISTER_HOOK, though
+	it is not used yet.
+	* inftarg.c (child_detach):  Pop the child_ops vector if the
+	detach is successful.
+	* remote-nindy.c (nindy_create_inferior):  Don't push a new
+	nindy_ops since nindy uses the same one for execution and memory
+	examination anyway.
+	* core.c (core_ops):  Use child_attach and child_create_inferior
+	rather than default attach and create_inferior functions.
+
+	Handle floating point registers in core files.
+
+	* sparc-xdep.c (fetch_core_registers):  Rewrite for float support.
+	* sun3-xdep.c (fetch_core_registers):  Rewrite for float support.
+	This version untested since BFD doesn't yet support sun3 core
+	files.
+	* hp300hpux-xdep.c:  Rewrite fetch_core_registers to new calling
+	conventions.  Fix comments and style.  This version has not
+	been compiled yet, since we have no HP inhouse.
+	* core.c (get_core_registers):  Look for two sections, ".reg"

+	(init_source_path):  New default source path is "$cdir:$cwd".
+	(dir_command):  Handle variable arguments ($cdir, $cwd).
+	(source_info):  Print "Compilation directory" rather than
+	"Originally compiled in" to remind people of $cdir.
+	(openp):  If the path contains $cwd, use current directory.
+	(open_source_file):  If compilation directory is known, replace
+	first $cdir in path with the compilation directory.
+	(print_source_lines):  Even if we can't print the lines, set the
+	current symtab and line for future commands like "info source" or
+	"breakpoint".  Also, error message now contains the file name,
+	line number, and file access error message.
+	(_initialize_source):  Fix help text to describe changes.
+	* main.c (cd_command):  Forget cached source info when we chdir.
+	* utils.c (strstr):  Add simple implementation.
+
+Tue Mar  5 01:41:40 1991  John Gilmore  (gnu at fowanton.cygnus.com)
+
+	* coffread.c (read_one_sym, init_linetable, init_stringtab):
+	Byte-swap COFF symbol tables if necessary when reading them in.
+	Use complain() to replace error message in one spot.  Needs
+	corresponding change in bfd/coff-code.h to make some symbol
+	swapping routines non-static.
+
+Mon Mar  4 00:53:40 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	Merge changes from Eirik Fuller, for UTek.

+	remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
+	symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c:  Eliminate
+	declarations of errno.
+
+	* remote-eb.c:  Define B19200 and B38400 as EXTA and EXTB.
+
+	* remote-vx.c:  Include <sys/time.h> for UTek; Sun gets it via
+	<rpc/rpc.h> and <rpc/types.h>.
+
+Sat Mar  2 15:47:55 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	* i960-tdep.c (examine_prologue):  Add new argument limit,
+	which stops the scan at the end of the prologue, or at the PC.
+	This fixes a problem where it walks down into the code for the
+	user's statements if that code looks like function prologues.
+	Mark Fox and I have been bouncing this code back and forth, making
+	small changes to it.  Callers changed to match.
+
+Tue Feb 26 01:47:07 1991  Cygnus John Gilmore  (cygnus at yuba)
+
+	Cleanup for gdb-3.94 release final:
+
+	* Makefile.dist:  Remove remote-vx.c, remote-nindy.c, and all
+	the .c files from vx-share and nindy-share, from the various 
+	macros, since they are not found via ALLDEPFILES.
+	(SFILES):  Add tm-i960.h.
+	(alldeps.mak rule):  Break out ALLDEPFILES_MAINDIR and
+	ALLDEPFILES_SUBDIR.  List all the nindy and vxworks subdir files
+	in the SUBDIR list.
+	(TAGFILES_MAINDIR):  Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
+	(gdb.tar.Z):  Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
+
+Mon Feb 25 16:02:35 1991  Cygnus John Gilmore  (cygnus at oldman)
+
+	* am29k-tdep.c:  Add contribution line.
+	(examine_prologue):  Cache information about function prologues in
+	the misc-function-vector to avoid lots of references over the
+	serial line while examining instructions.
+
+	* core.c (core_close):  New function made from cleanup_core.
+
+	* core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
+	remote-vx.c, remote.c, target.c, target.h, 
+	Update target_ops vector to add attach, close, and load entries.
+	Use add_syms_addr_command, not add_file_addr_command, for
+	add_file.  Break out close routine from existing code.
+
+	* dbxread.c (really_free_pendings):  Don't free pending_blocks;
+	they are in an obstack.
+	(read_dbx_symtab):  Relocate end_of_text_addr in the psymtab.
+	Lint.
+	(define_symbol):  Add symbol type parameter; change callers;
+	pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
+	it to influence the symbol class on the i960.
+	(define_symbol):  Swap LOC_CONST's into target byte order.
+
+	* exec.c (exec_close):  New function.
+	(exec_file_command):  Call it.
+
+	* findvar.c (read_relative_register_raw_bytes):  Doc byte order,
+	Fix byte order of frame pointer.
+	(read_var_value):  Result of 0 if var's value can't be found,
+	e.g. missing FRAME_ARGS_ADDRESS.  Byte-swap LOC_CONST and
+	LOC_LABEL values to target order.  Add LOC_LOCAL_ARG.
+	(locate_var_value):  Use read_var_value and use its lazy address
+	as the location of the var's value.  Lint.
+
+	* i960-pinsn.c (next_insn):  Add routine from vxgdb for scanning
+	instructions.       
+
+	* i960-tdep.c (arg_address, i960_frame_find_saved_regs):  Remove
+	obsolete Intel versions in favor of vxgdb versions.
+	(check_host, byteswap, byteswap_val, reorder_val):  Eliminate
+	code dealing with byte order of values, which Intel did in host byte
+	order rather than gdb-4's target byte order.
+	(i960_frame_chain_valid):  Move to nindy-tdep.c.
+	(examine_prologue, skip_prologue, frame_find_saved_regs,
+	frame_args_address, leafproc_return, saved_pc_after_call,
+	pop_frame):  Add vxgdb versions from Mark Fox.
+	(examine_prologue, frame_struct_result_address):  Add code
+	to deal with the saved value of G13 (struct return address
+	pointer).
+	(frame_args_address):  Modify Mark's version to prefer the
+	saved value over the current value in the topmost frame.
+	Cache result in the frame info to avoid performance hair in
+	callers.
+	(print_fault):  Add gdb960 code for printing faults.
+	(_initialize_i960):  Actually call check_host.
+
+	* ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
+	add stub routines.  FIXME, these currently just return zero!
+
+	* infcmd.c (program_info):  Use PRINT_RANDOM_SIGNAL.
+	(attach_command):  Call target_attach, not target_open, now.
+
+	* infrun.c (normal_stop):  Make global, not static, for vx_attach.
+	(child_attach):  Rename from child_open.
+	(wait_for_inferior): Use PRINT_RANDOM_SIGNAL.  If stop_pc is zero,
+	don't confuse it with a zero step_resume_break_address. 
+
+	* inftarg.c (child_detach):  Eliminate inferior_pid test.
+	(child_files_info):  Clean up message a bit.
+	(child_ops):  Use child_attach, not child_open, to attach.
+
+	* mem-break.c:  #ifdef out the whole file if BREAKPOINT is not
+	set (e.g. on VxWorks or NINDY).  Move read_memory_nobpt from
+	findvar.c to here, since it depends on the contents of the
+	shadow_contents of breakpoints, but keep if #if 0 since it is
+	never called.
+
+	* nindy-tdep.c:  New file, contains nindy_frame_chain_valid, moved
+	from i960-tdep.c.
+
+	* printcmd.c (address_info):  Handle LOC_LOCAL_ARG.  Lint.
+	(ptype_command, display_command):  Eliminate have_inferior_p and
+	have_core_file_p in favor of target_has_stack or
+	target_has_execution.
+	(print_frame_args):  Handle LOC_LOCAL_ARG.  Eliminate duplicate
+	code for actually finding the values of arguments, though we still
+	keep track of the maximum stack offset for use in printing unnamed
+	arguments.  Handle missing FRAME_ARGS_ADDRESS.
+
+	* remote-nindy.c (i960_print_fault):  Move to i960-tdep.c.
+	(struct nindy_regs):  Define registers passed to/from nindy.
+	(nindy_fetch_registers, nindy_store-registers):  Translate between
+	nindy and GDB formats for the registers.
+	(dcache_init):  Statically allocate the cache, since it was being
+	allocated by a malloc that was never freed anyway.
+	(nindy_create_inferior):  Error, not core dump, if no exec file.
+	(nindy_before_main_loop):  Use target_load, not target_add_file.
+
+	* remote-vx.c (net_load):  Specify large timeout for load
+	requests.  Allow user to break out with INTERRUPT.
+	(net_break):  Remove useless code, clean up.  Change callers.
+	(parse-args, skip_white_space, find_white_space):  Clean up arg
+	parsing to cope with quoted strings.
+	(net_wait, net_quit):  Never call error, just return status.
+	(vx_read_register, vx_write_register):  Cleanup status checking.
+	#ifdef the code based on which CPU we are using (960 or 68k),
+	FIXME, this should be completely general but it isn't yet.
+	(vx_xfer_memory, vx_resume):  Cleanup status checking.
+	(vx_run_files_info):  Improve message.
+	(vx_load_command):  Renamed from vx_add_file_command.  Allow load
+	to be interrupted.
+	(net_ptrace):  Remove unused routine.
+	(vx_wait):  Adopt code from vxgdb960 to cope with broken
+	connections to target machine and prompt to disconnect.  Remove
+	debug printouts.  Map some EVENT_'s to SIGnals.
+	(add_symbol_stub, vx_open):  Print names of object files we found,
+	and "ok" if we read their symbols OK.  Clarify output in general.
+	(vx_attach, vx_detach, vx_kill):  Add these commands.
+	(vx_convert_from_virtual, vx_convert_to_virtual):  Simplify.
+	(vx_run_ops):  Turn off all_mem, to avoid spurious msg in the
+	"info files" output, and create_inferior, since we already have
+	an inferior.
+
+	* stack.c (frame_info):  Replace Frame_unknown with 0.
+	(print_frame_arg_vars):  Handle LOC_LOCAL_ARG.
+	(return_command):  Pop until the PC matches as well as the FP,
+	so it works even if the FP is shared with another function,
+	as in "frameless" or "leaf" procedures.
+
+	* symfile.c (load_command):  renamed from add_file_target_command.
+	(add_syms_addr_command):  renamed from add_file_addr_command.
+	(add_syms_command):  Stub to call target_add_syms.
+	(_initialize_symfile):  Change command names and descriptions,
+	add-file => add-syms, and load from alias to its own command.
+
+	* target.c (kill_or_be_killed, maybe_kill_then_attach,
+	maybe_kill_then_create_inferior):  Default for attempts to start
+	a process, if one is already running, is to ask about killing
+	it and retry if yes.
+	(upstack_create_inferior):  #if-0 it, strata obsolete it.
+	(push_target, unpush_target, pop_target):  to_close() a target
+	before unstacking it. 
+	(target_info):  Renamed from target_files_info.
+	(_initialize_targets):  Rename "i files" as "i target", accessible
+	under both names.
+
+	* target.h:  Improve comments about the target_ vectored routines.
+
+	* tm-i960.h:  Remove NINDY-specific stuff to tm-nindy960.h.
+	Convert commenting style to standard GNU style.
+	(DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
+	(SKIP_PROLOGUE):  No longer a no-op.
+	(SAVED_PC_AFTER_CALL):  Now handles leaf procedures.
+	(*_REGNUM):  Sort register numbers.
+	(REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
+	MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
+	REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW):  Float regs
+	are now 10 byte extendeds, not 8 byte doubles.
+	(FRAME_CHAIN_VALID):  Make this config-dependent, since it differs
+	for nindy versus vxworks targets.  FIXME, this should possibly go
+	in the target vector.
+	(EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO):  Cache both
+	frame_saved_regs and arg pointer with each frame.
+	(FRAMELESS_FUNCTION_INVOCATION):  New leafproc support.
+	(FRAME_ARGS_ADDRESS):  Use cached result.
+	(FRAME_ARGS_ADDRESS_CORRECT):  New, avoids g14 guessing.
+	(FRAME_FIND_SAVED_REGS):  Change arg to subsidiary fn.
+	(PRINT_RAMDON_SIGNAL):  Call print_fault.
+	(POP_FRAME):  Now works.
+
+	* tm-nindy960.h:  Break this off tm-i960.h.  NINDY-specific
+	option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
+	BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
+	(ADDITIONAL_OPTION_HANDLER):  use target_load, not
+	target_add_file.
+	
+	* tm-vxworks960.h:  Break this off tm-i960.h.  VxGDB specific
+	startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
+
+	* valarith.c (value_subscripted_rvalue):  Avoid handling
+	floats and doubles specially; it gave alignment errors.  Lint.
+
+	* valops.c (value_of_variable, value_of_this):  Error if unknown
+	value.
+
+	* valprint.c (print_floating):  Bcopy rather than pointer-deref,
+	to avoid alignment problems.
+	(value_print):  Handle unknown value address.
+	(cplus_val_print):  Two args are ignored; remove them.  Change caller.
+	(val_print):  Use unpack_long rather than pointer-deref.
+
+	* values.c:  Lint.
+	(unpack_long, unpack_double):  Use bcopy rather than pointer-deref
+	to avoid alignment problems.
+	(value_being_returned):  Error if return value unknown.
+	(set_return_value):  Add bogosity warning, FIXME.        *
+
+	* TODO:  A woman's work is never done.
+
+	* Makefile.dist:  Distribute REMOTE_OBS into tconfig files.
+	Separate INCLUDE_CFLAGS for use with lint.  Add LINTFILES.
+	Add ieee-float.o to OBS.
+	* tconfig/{nindy960,vxworks68,vxworks960}:  Include the desired
+	REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
+	* tconfig/i960:  FIXME.  Half-merge, produce warning if config'd.
+
+	Changes to generalize the VxWorks RPC protocol slightly, to handle
+	i960 as well as 68000.
+
+	* vx-share/dbgRpcLib.h (VX_SOURCE_STEP):  Add.
+	* vx-share/reg.h:  Produce i960 regs #ifdef I80960
+	* vx-share/xdr_ptrace.c:  Skip FPA registers if 960.
+	* vx-share/xdr_rdb.h:  Add SOURCE_STEP struct and xdr decl.
+	* vx-share/xdr_rdb.c:  Add xdr_SOURCE_STEP routine.
+	* vx-share/xdr_regs.c:  Add xdr_regs, xdr_fp_status, xdr_ext_fp
+	for i960.  Change xdr_vectors to xdr_opaques for 68k registers,
+	so they will move in target byte order rather than network
+	byte order (happens to be the same).	
+
+Mon Feb 25 03:41:44 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	* tm-convex.h (END_OF_TEXT_DEFAULT):  Remove #if 0'd block.
+
+Sun Feb 24 00:55:53 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	* am29k-pinsn.c, 
+	Add contribution lines to various files, showing where they
+	came from.
+
+	* breakpoint.c (break_insn, check_break_insn_size,
+	read_memory_nobpt):  Remove to mem-break.c.
+
+	* xm-*.h, param-no-tm.h, tm-29k.h, valprint.c:  Change BYTE_ORDER to
+	HOST_BYTE_ORDER.
+
+	* tm-29k.h (STAB_REG_TO_REGNUM):  Warn user if symbol table
+	entry has bad register number.  This change is not
+	tested in this release, FIXME.
+
+	* frame.h:  Eliminate Frame_unknown in favor of a simple zero.
+	tm-vax.h:  Ditto.
+
+	* value.h:  Force value's contents field to be aligned to hold
+	at least a double or a long long (if supported).  This avoids
+	doing bcopy's in and out of the contents field.
+
+	(step_1):  Avoid coredump under obscure circumstances when we
+	have no frame.
+
+	* symtab.h (misc_info):  Add field to misc function vector for
+	any kind of cached information the target code desires.  AMD
+	29000 uses this to avoid repeating examine_function_prologue's.
+
+	* coffread.c:  Lint.  Remove static symfile, read_section_header.
+	core.c (have_core_file_p):  Lint: remove.
+	expprint.c (print_subexp):  Lint.
+	infptrace.c, valops.c, valprint.c:  lint.
+
+	Roll in changes from vxgdb-5.0.1:
+
+	* symtab.h:  Comment byte order of each address class.  Add
+	LOC_LOCAL_ARG for frame-relative args (960).
+	expread.y:  Use LOC_LOCAL_ARG where LOC_ARG is used.
+	symtab.c, symmisc.c:  ditto.
+	
+	* infrun.c (init_wait_for_inferior):  Clear stop_signal.
+
+	* remote.c (remote_resume):  Error if resume with a signal.
+
+	* symfile.c (prim_record_misc_function):  Clear misc_info.
+	(fill_in_vptr_fieldno):  Check stub type of arg.
+
+	* valops.c (value_cast):  Avoid looking up names of types whose
+	name we don't know, to prevent coredump.  Sun CC produces typedef
+	rtx and the name of *rtx is zero...
+
+Mon Feb 18 21:16:25 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	Roll in changes from final AMD 29000 port (Tiemann).
+
+	tconfig/am29k:  Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
+	for ../include/a.out.encap.h.  This might not work now that BFD
+	is separately compiled.  Instead, BFD support for encap will have
+	to translate machine type 29k into the right COFF_MAGIC.
+	
+	* infcmd.c: Remove references to inferior_pid that aren't used
+	in actual ptrace calls; use target_has_execution, etc.
+	(have_inferior_p):  Remove function.
+	(program_info):  Print target info rather than "process number";
+	avoid gratuitous messages unless from_tty.
+	(run_stack_dummy, finish_command):  Set proceed_to_finish.
+	infrun.c: Remove inferior_pid refs.  Decl & init proceed_to_finish.
+	main.c:  Lint.  Lose have_inferior_p().
+	inferior.h (have_inferior_p):  Remove, lint.
+	(proceed_to_finish):  Add flag to ask that all regs be saved
+	by normal_stop, for the few commands that need it, speeding up
+	serial I/O.  Add comments to stop_registers.
+
+	* remote-eb.c:  Remove newline from breakpoint message we grep
+	for.  Never time out when running the user program.
+	
+
+
+Wed Feb 13 15:34:40 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	Roll in changes from vxgdb-5.0.1:
+
+	* dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
+	symbol in its raw form, we are processing an unlinked ".o" file.
+	See if the target environment has assigned it an address, using
+	target_lookup_symbol (VxWorks does), and enter it into the symtab
+	that way.
+
+	* tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID):  Override usual
+	68k versions for a simpler version that assumes zero FP at bottom.
+	Fixes bug of truncated stack reports.
+
+	* target.h (target_lookup_symbol):  Define this routine's args
+	and result, finally.
+
+	* target.c (nosymbol):  Default routine for target_lookup_symbol.
+	(target_default):  Default lookup_symbol and call_function too.
+	(files_info):  Only print has_all_memory warning if a non-dummy
+	target follows.
+
+	* remote-vx.c (vx_read_register, vx_convert_to_virtual,
+	vx_convert_from_virtual): If target does not have floating point,
+	zero register "values", and avoid doing cross-net conversions.
+	(vx_lookup_symbol):  Rename net_lookup_symbol, add to vectors.
+	(vx_open):  Rearrange code that attaches to target and reads
+	symbols for all loaded modules, to work if some of the modules
+	are not accessible.  Add symbol_stub() and add_symbol_stub()
+	as callbacks from catch_errors().  Allow connect attempt to be
+	interrupted painlessly with ^C (FIXME, there are still some bugs
+	if the interrupt happens during symbol reading.).  Print
+	final message with puts_filtered, since symbol messages are
+	now filtered too.
+
+	Misc cleanup:
+
+	* main.c (catch_errors):  Only print errstring if non-null.
+	(command_loop):  Avoid an ioctl per command to test ISATTY.
+
+	* remote-vx.c (net_load):  make static; avoid sophomoric msg.
+	(vx_xfer_memory):  Return correct result!
+	(vx_files_info):  Indicate whether target has float or not.
+	(vx_lookup_symbol):  Complain, not error, if target gone.
+	(vx_open):  Print "Connected" msg before disabling immediate-quit.
+	[FIXME:  lookup_symbol and vx_open changes need testing.]
+
+	target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
+	tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
+	contributor lines and update copyrights to 1991.
+
+	Changes from an attempted H-PUX host port:
+
+	* infptrace.c (PT_ATTACH, PT_DETACH):  Handle HP/UX, which 
+	defines PT_ATTACH and PT_DETACH but not PT_KILL.
+	* remote-eb.c (eb_open):  Misplaced endif kills sysv H/PUX.
+	* remote-vx.c: include <sys/time.h> for HPUX.
+	* hp300hpux-xdep.c (fetch_core_registers):  Rewrite old
+	"core_file_command" routine to BFD regime.  May not work yet.
+
+	Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
+
+	* xgdb.c: Replace X10 version with some VJ version.
+	(FIXME:  Its copyright assignment is not on record.)
+	* xgdb.c:  Update include files to X11R4 (Xaw crud).
+	(xgdb_display_source, create_text_widget): fix call to
+	get_filename_and_charpos.  Rewack source window stuff for X11R4
+	(gleaned from include files, and "nm's" of binary libraries, since
+	I had no doc available).
+	(append_selection, append_selection_word): Disable with FIXME
+	since R4 changed interface here.
+	(create_buttons):  Add back the old set of buttons.
+	(xgdb_create_window):  Fix call to XtInitialize (&argc not argc).
+
+	* Makefile.dist (xgdb, xgdb-init.c):  Update for X11R4 on Suns.
+	Roll VERSION to 3.94 (not yet final though).
+
+Sat Feb  9 09:46:25 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	* obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
+	obstack_int_grow, obstack_int_grow_fast):  Eliminate
+	cast on left of assignment, which gives MIPS cc fits and is
+	not Standard C.
+
+	* sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
+	F_ALIAS.  Use printf, not fprintf, when not passing a file
+	pointer...
+	(compare_opcodes): Check that identical instructions have
+	identical opcodes, complain otherwise.
+
+	* sparc-opcode.h (st %fsr):  Fix opcode "lose" mask.  This
+	was reported by Roland McGrath.
+	(unimp): Only match if exactly zero instruction.  (Roland)
+	(branches and traps):  Generate all variations of these
+	instructions with macros, based on a single call that defines
+	each condition name and its binary representation.
+	(set):  Turn on alias bit, to avoid test in sparc-pinsn.c.
+
+	* valprint.c (val_print_fields):  Take, and use, format parameter.
+	This means that "p/x struct" again prints the elements in the
+	desired format.  Changed callers.
+
+	* stack.c (frame_info):  Use filtered output, and indicate wrap
+	points.  Remove kludgy formatting designed to avoid line wrap.
+
+	* utils.c (wrap_here):  If the line is already full (because
+	we had printed a long indent or long wrapped string), do an
+	immediate newline-and-indent.
+
+	* m68k-pinsn.c (print_insn_arg): Bugfix from
+	ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
+	instruction is incorrectly disassembled as bkpt #8.
+
+	* dbxread.c (end_psymtab): Bugfix from Peter Schauer
+	<pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
+	breakpoint in a *.y file gdb will say Reading in symbols for *.y...
+	and then will dump core (sometimes). I traced it back to an
+	uninitialized symfile_name in psymtab_to_symtab.
+	(const_vol_complaint):  Add quotes to message.
+	(define_symbol):  Only believe line number if gcc_compiled.
+	Avoid allocating symbol if we will not return it.
+
+	Add target strata support so that newly established targets go
+	into their right place in the target stack (e.g. a new exec file
+	doesn't wipe out the ability to access the running process).
+
+	* target.h, core.c, exec.c, inftarg.c, remote-eb.c,
+	remote-nindy.c, remote-vx.c, remote.c, target.c:  Add to_stratum
+	and initialize it properly in all the targets.
+
+	* target.h:  Document strata.  Change return type of push_target.
+
+	* target.c (nomemory):  new function for dummy memory access.
+	(tcomplain):  Rename complain, now also used in symfile.c.
+	(push_target):  Push targets within strata.  New return value shows
+	whether new target is on top of stack or not.  Always keep dummy
+	target on stack.
+	(target_files_info):  Ignore dummy target.
+
+	* core.c (core_open):  Warn user, and skip accessing file, if the
+	core target is not the topmost target in the stack.
+	* remote-nindy.c (nindy_create_inferior):  Avoid unpush_target, now
+	already handled.
+
+	* remote-vx.c:  Remove vx_prepare_to_store from vxworks memory
+	target_ops, it doesn't belong there since we have no regs there.
+	Change name of target from machine => memory to clarify.
+
+Thu Feb  7 16:32:09 1991  John Gilmore  (gnu at spiff.cygnus.com)
+
+	* Freeze version 3.93 for release.
+
+	* Makefile.dist:  Handle vx-share and nindy-share subdirs
+	properly when building gdb.tar.Z.
+
+	* symtab.c:  lint; add no_symtab_msg to consolidate the messages
+	printed in various places, so I could change just one copy.
+
+	* dbxread.c, coffread.c:  Change references to bfd->iostream
+	to cast to FILE *, now that BFD avoids needing types defined
+	in other header files.
+
+Tue Feb  5 21:39:35 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	* command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
+	infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
+	sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
+	(actually gcc -Wall).
+
+	* dbxread.c:  Remove first_global_sym, last_global_sym, since
+	they are never referenced.
+
+	* defs.h (baud_rate):  Declare.
+	main.c: Define it, and add the -b option to set it.
+
+	* gdb-int.texinfo:  Add text on how to define a new host or target
+	architecture, prompted by Per Bothner's questions about MIPS
+	support.
+
+	* gdb.texinfo:  Document "complaints".  Change doc of -q since
+	gdb no longer prints the copyright and blurb if you specify a file
+	name to be debugged (just like Emacs).  Add doc for Nindy-specific
+	command line flags for specifying target serial port and such.
+	Update copyright to 1991.
+
+	* gdbcore.h:  Remove a large mass of now-useless crud, since BFD
+	has taken over for us the job of ripping up executable files.  The
+	crud caused Per Bothner's port to not compile.
+
+	* infrun.c (normal_stop):  Avoid printing "Program exited
+	normally" if we are in batch mode.  This allows a GDB which
+	executes a program on a target system, to behave like a Unix
+	command (input from stdin, output to stdout, no extraneous
+	output).
+
+	* main.c (main):  Allow additional machine-dependent command line
+	options to be specified with the ADDITIONAL_OPTIONS,
+	ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
+	ADDITIONAL_OPTION_HANDLER macros.  Also allow machine-dependent
+	processing to occur just before the main loop with
+	BEFORE_MAIN_LOOP_HOOK.  
+	(main):  If a "core file" argument is specified, and it is not a
+	core file, try it as a process ID to attach.  
+	(symbol_completion_function):  Attempt to cope with 
+	"show screen-" TAB, not very successfully.  This needs more work,
+	FIXME.
+	(batch_file):  New function, returns whether we are reading
+	commands from an interactive tty on stdin, or from somewhere else.
+	Called by normal_stop since it doesn't get from_tty passed down
+	to it like many commands do.
+
+	* remote-nindy.c:  Handle command line options for nindy
+	connection.
+	(nindy_before_main_loop):  Prompt user for tty name if they
+	don't specify it before getting to the interactive command loop.
+
+	* tm-i960.c:  Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
+	and -r command line options.  Also add hook before main loop
+	to make it easy to specify a tty.
+
+	* TODO:  More things to do, one done.
+
+Mon Feb  4 23:57:39 1991  John Gilmore and Mike Tiemann  (at cygint.cygnus.com)
+
+	* dbxread.c:  Make complaint() calls pass pointer, not struct.
+	Add complaints about badly formatted C++ type information
+	(const/volatile indicator, and parse errors resulting in
+	error_type).  Fix C++ virtual member fn comment.
+	(read_struct_type):  Avoid bumping pointer if we got a parse
+	error; this prevents our walking beyond the end of a string.
+	Terminate loop on null char as well as semicolon.
+	(process_one_symbol):  Fix the LBRAC fix so that it uses the
+	last previous SLINE, FUN, or SO record's PC address.  C++ debug
+	symbols did not have SLINE records in a useful order compared
+	to the LBRAC records.
+	(define_symbol):  Handle "catch" records.
+
+	* symtab.c (check_stub_type):  Added new complain
+	`stub_noname_complain' and added a consistency check to
+	keep the debugger from crashing when finishing from an
+	exception frame.  A real fix will be needed later.
+
+Sat Feb  2 10:43:05 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	* infcmd.c (attach_command):  Make global.
+
+	* Makefile.dist (REMOTE_OBS):  Make these compile by default,
+	but make them easy to comment out.  Perhaps later they should
+	be enabled by what CPU you configure for?  FIXME.
+	(VERSION):  Roll to 3.93.
+	(pinsn.o):  Remove rule for obsolete file.
+	(dbxread.o,coffread.o,mipsread.o):  Use ${srcdir} explicitly.
+
+	Run down a problem that manifested by printing the wrong function
+	name in stack traces of read_ofile_symtab.  Turned out that the 
+	problem was the SunOS 4.1.1 (and previous) C compiler outputs
+	the LBRAC symbol with an address in the *data* segment, which
+	blew our binary search through the blocks.
+
+	* dbxread.c: Use the complain() facility consistently to bitch
+	about problems in the symbol file we are reading.
+	(finish_block):  Add code to check the nesting of the blocks;
+	complain and Procrust them to fit if wrong.
+	(make_blockvector):  Check the order of the blocks, complain 
+	[but don't cope] if wrong.
+	(process_one_symbol):  ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
+	symbols to be sure their PC value is greater than the last SLINE
+	(line number) symbol we've seen, complaining and adopting the
+	SLINE PC value if wrong.
+
+	* symfile.h (struct complaint, complaint_root, complain, 
+	clear_complaints):  Add.
+	* symfile.c (complain, complaint_root, clear_complaints):  Add
+	facility to deal with non-fatal complaints and to regularize their
+	suppression.
+	(symbol_file_add):  Clear complaint counters to allow new complaints.
+	(initialize_symfile):  Add 'set complaints' and 'show complaints'.
+
+	* dbxread.c (dbx_symfile_read):  Remember the address and size
+	of the string table for the main symbol file, so we won't read it
+	more than once.
+	(dbx_psymtab_to_symtab):  Fix the check for main symbol file,
+	to avoid reading the string table yet again.  Lint.
+	(throughout):  Improve filtered output, including word wrap.
+	(read_range_type):  Improve Bothner's fix to handle other types too.
+
+	* utils.c:  Improve line wrap implementation.  Handle unlimited
+	width by making chars_per_line unsigned.
+	(puts_filtered):  New, easy, function.	
+
+	* defs.h (puts_filtered):  add.
+
+	* mipsread.c (compare_symbols, sort_symtab):  Remove these fns,
+	call the identical sort_symtab_syms() in symfile.c instead.
+
+	* expread.y:  Suggest the `file' command rather than `symbol-file'.
+
+	* command.h (enum var_types):  Add zinteger for seroable
+	unsigned integer.
+	* command.c (do_setshow_command):  Handle var_zinteger.  Restructure
+	nested if's into a switch.
+
+	* breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
+	we did not stop because of a breakpoint (it must have been for
+	some other reason, like a "stepi"), so don't print anything.
+
+	* symtab.c: Include <sys/types.h> all the time.  Now that BFD
+	doesn't include <sys/types.h>, old SunOS's require it for
+	<sys/stat.h>.
+
+Sat Feb  2 10:39:15 1991  Per Bothner  (bothner@cs.wisc.edu)
+
+	A test port of gdb-3.92.6 to the Sony NEWS.
+
+	* Makefile.dist
+	Don't normally link in remote- or vx stuff.
+	Some of it doesn't compile, and it wastes space for 99%	of the users.
+	Remove reference to no-longer-used HAVE_VPRINTF.
+	Fixed BFD_DEP typo to BFD_DIR.
+	* dbxread.c
+	Fix cast in arg to bfd_h_getlong.
+	Make char *prefix be const.
+	Fix how certain range types are mapped into builtin unsigned int types.
+	* infrun.c
+	Remove 2 #includes. They cause errors (on Sony, at least),
+	and aren't needed (they wern't in earlier versions).
+	* printcmd.c
+	print_address_symbolic should never demangle labels
+	(since it prints *assembler-level* labels).
+
+	       [This was superseded by the change to printcmd below.]
+
+	* utils.c
+	Add some "volatile" return types to avoid warnings.
+	If MISSING_VPRINTF add vprintf function and not just macro
+	(since vprintf is used in printcmd.c).
+	* valprint.c
+	Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
+	(The latter isn't grokked by some PCC-based compilers.)
+
+	     [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
+
+	Make chunk size of dont_print_obstack 32*4 instead of default 4096.
+	* nindy-share/coffstrip.c
+	Added some forward declarations (otherwise, gcc complains
+	about implicit extern redefined as static).
+
+Sun Jan 20 02:38:19 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	Changes inspired by Per Bothner:
+	* printcmd.c (print_address_symbolic):  Take additional parameter
+	specifying whether to demangle.
+	(print_address):  Pass in asm_demangle to control demangling.
+	(print_address_demangle):  New fn, takes explicit arg to control
+	demangling.
+	* utils.c:  Add new vars demangle and asm_demangle, and let them
+	be set and shown.
+	(fputs_demangled):  If !demangle, just print the argument.
+	(fprint_symbol):  If !demangle, just print raw symbol.
+	* valprint.c (val_print):  Call print_address_demangle rather than
+	print_address, to cause demangling to depend on the global
+	rather than assembler-level demangling setting.
+	* WHATS.NEW, gdb.texinfo:  Document.
+
+	* main.c (show_command):  Show all settings if no arg.
+	(initialize_main):  Make "info set" the same as naked "show".
+	* command.c (cmd_show_list):  Handle prefix commands in the
+	list, and print the name of the setting as well as its English
+	description and value.
+
+	Allow gdb functions to specify where a line should wrap if it
+	exceeds the size of a terminal line.  Use it to make the output
+	prettier.
+	* utils.c (set_screen_width_command):  New fn, mallocs a buffer
+	of the right size when screen width changes.
+	(set_screensize_command, screensize_info):  Remove #if 0'd fns.
+	(wrap_here):  New fn, indicates a point in the output where we
+	should wrap the line rather than just letting it overflow at a
+	random place.
+	(fputs_filtered):  Implement wrapping.
+	(n_spaces):  New fn, returns a pointer to N spaces.
+	(print_spaces_filtered):  Use n_spaces.
+	* defs.h (n_spaces):  Declare.
+	* stack.c (print_frame_info):  Wrap with 4-space indent after
+	fn name and before filename and line number.
+	* printcmd.c (print_frame_args):  Wrap with 4-space indent
+	before each argument name is printed.
+	* valprint.c (value_print):  Wrap with no indentation before
+	each repetition.
+	(val_print_fields):  Wrap with indentation relative to nesting
+	level before each field name.
+	(val_print):  Wrap with nesting indentation before array elements.
+	* command.c (do_setshow_command):  Avoid extra newlines,
+	wrap with 4-space indent around values printed, end with period.
+	* WHATS.NEW, gdb.texinfo, gdb-int.texinfo:  Document.
+
+	* breakpoint.c (breakpoint_1):  Implement addressprint for
+	"info breakpoints" display.  Change file name and line number
+	format to " at file:nnn" rather than " (file line nnn)".
+	* gdb.texinfo:  Document.
+
+
+Fri Jan 18 07:21:25 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	Frozen for gdb-3.92.6 release.
+
+	README, WHATS.NEW:  Update for 3.92.6 release.
+
+	tconfig/{altos, i386v, i386v32, m88k, umax}:  Eliminate
+	coffread.o from configs since it is now built by default.
+	tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
+	i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
+	pyramid, symmetry, vax, vxworks68}:  Eliminate dbxread.o
+	from configs since it is now built by default.
+
+	Makefile.dist: Update for release 3.92.6.  Handle files that
+	have been moved to ../include, ../getopt, or ../bfd.  Add
+	saber.suppress and tests directory.  Add config.status to
+	the release (it will say "none").
+
+	coredep.c:  Minor formatting fixes.
+
+	These changes were made in early December but only checked in now:
+	* nindy-share/Onindy.c, nindy-share/coffstrip.c,
+	nindy-share/nindy.c:  lint
+	* nindy-share/nindy.c (ninStopWhy):  Don't byteswap the 
+	register values coming back from the target; we store values
+	in target byte order everywhere.
+
+Wed Jan 16 19:01:37 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	* am29k-opcode.h, am29k-pinsn.c:  Add 29050 opcodes.
+
+	* valprint.c (cplus_val_print, val_print_fields):  New functions,
+	which print C++ objects.  They conspire to avoid printing a
+	virtual base class more than once, following all the twists and
+	turns of C++ virtual base rules.
+	(val_print):  Call the above rather than do it by hand.
+
+	* symfile.c (symbol_file_add):  Only reset symfile_mtime for main
+	symbol file, not for added files like shared libs.  This really
+	needs to be generalized to a timestamp per file.
+
+	* core.c (cleanup_core):  Avoid coredump if no core file.
+	
+	* config.gdb:  Accept -host or -target in place of +host or
+	+target.
+
+	* coffread.c (find_linenos):  Avoid desupported BFD interface
+	to line numbers.  We still read them manually rather than using
+	BFD's "generic" features.
+
+	* gdbrc.tex, threecol.tex:  Add GDB reference card and its
+	formatting code.
+	Makefile.dist:  Add refcard to OTHERS list for creating tar files.
+
+	* Makefile.dist:  Eliminate use of $< in explicit targets.
+
+	* readline/Makefile:  Use $< rather than $*.c, which does not
+	include the VPATH in GNU Make.
+
+	* tconfig/i960-bout, tconfig/i960-coff:  These are identical
+	copies of tconfig/i960, added for global configuration
+	compatability.  All i960 versions can read both coff and b.out.
+
+	* tm-88k.h:  Fix multiline macro that lacked \'s.  Remove
+	COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
+	automaticaly.
+
+	* TODO:  Think of more things to do.
+
+Wed Jan  2 19:09:29 1991  John Gilmore  (gnu at spiff.cygnus.com)
+
+	tconfig/{am29k,i960,sun2*,sun3*,sun4*}:  Eliminate config
+	of sdb versus dbx debug symbols.  Add kludge for 68881 80-bit to
+	64-bit float conversion.
+
+	tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3:  Make
+	equivalent to sun?os4 so global config works.
+
+Wed Jan  2 18:20:51 1991  John Gilmore  (gnu at spiff.cygnus.com)
+
+	Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
+	
+	* main.c:  Only declare linesize once; declare pagesize not at
+	all, since it is never used.
+	(main):  Clear newly allocated line before it is used.
+
+Fri Dec 28 00:13:42 1990  John Gilmore  (gnu at cygint)
+
+	Further stabilization for the Intel 960.
+
+	* Makefile.dist: Parameterize the location of the "include"
+	and "bfd" directories, as well as "getopt".  Add symfile.c.
+	Link in both dbxread and coffread.  Fix up "make depend" to
+	rewack the locations of include, bfd, and getopt in its output.
+
+	* README:  Document moving include files, improve some of
+	the other doc.
+
+	* coffread.c:  Move common code out to symfile.c.  Change
+	symbol_file_command style interface to use new *_symfile_init
+	and *_symfile_read interface under BFD.  Use BFD internal
+	info to locate line table, symbols, etc.
+
+	* core.c (core_fetch_registers):  Rename to get_core_registers
+	to avoid confusion with fetch_core_registers.
+	(register_addr):  Move to coredep.c, which is already machine
+	dependent.  This leaves core.c pretty clean of dependencies.
+
+	* coredep.c (register_addr):  Accept this routine from core.c.
+
+	* dbxread.c: Move common code (with coffread.c, etc) into new
+	symfile.c.  Each psymtab now contains a pointer to the
+	format-dependent function that knows how to read it in.  Make
+	some things static.  
+	(dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
+	(process_one_symbol): Add code to complain about a "compiler bug
+	we muzzle here", if we actually see it.
+
+	* eval.c (evaluate_subexp):  Insert missing "break" statements
+	in code that determines whether a variable is an lvalue in
+	memory, register, or whatever.	I detected this via a compiler
+	bug in which it *almost* mashed out the whole switch statement.
+
+	* gdb-int.texinfo:  Add minor sections on configuring gdb for
+	release, and about the README file.
+
+	* infcmd.c (registers_info):  Fix formatting somewhat.  Still
+	not as pretty as before, but it handles byte swapping.
+
+	* remote-nindy.c: If data cache routines are interrupted while
+	waiting for the remote end, be sure that any uninitialized cache
+	blocks are on the free list, not on the valid list!
+
+	* symfile.h: Flesh out this header file with all the various
+	routines and variables that have been merged in from dbxread.c
+	coffread.c, and symtab.c to symfile.c.
+
+	* symfile.c: New file, containing code common to dbxread.c,
+	coffread.c, and some code from symtab.c.  All generic code for
+	reading symbol files should be in here now.
+	(unrecord_misc_function):  Remove unused function.
+
+	* symtab.h:  Remove file-reading things to symfile.h.
+
+	* symtab.c:  Remove file-reading things to symfile.c.
+
+	* tm-i960.h:  Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
+	to decode i960 fault types.
+
+	* target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
+	target.c: Change type of the "resume" function from int to void,
+	since its result was never used.
+
+Sat Dec 22 02:51:40 1990  John Gilmore  (gnu at cygint)
+
+	* main.c:  Replace "stupid" with "caution"; you now "set caution
+	on or off".
+
+	* printcmd.c (print_scalar_formatted):  Fix typo in 'g' format
+
+	* infcmd.c (do_registers_info):  Call val_print to deal with the
+	byte order of the registers being printed.  FIXME, this makes
+	the formatting of the output uglier.
+
+	* infcmd.c (wait_for_inferior):  If PRINT_RANDOM_SIGNAL is
+	defined, call it for signals the debugger doesn't itself use.
+	The i960 uses this for more detailed fault information.
+
+	* remote.c (remote_open):  If arg is null, print help rather than
+	dumping core.
+
+	* sparc-xdep.c (register_valid):  Avoid declaring size, since
+	various modules will think of various sizes depending on the
+	architecture of their tm-file.  FIXME, we need protection against
+	actually entering one of those modules, which would clobber
+	storage if not for the target architecture compiled into gdb.
+
+	* stack.c (up_command, down_command):  Always print the frame
+	you arrive at.
+	(up_silently_command, down_silently_command):  New commands
+	for use in scripts.
+
+	* i960-pinsn.c (reg), i960-tdep.c:  Lint.
+
+	* i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
+	more parameters than it used to.
+
+	* findvar.c (registers):  Increase slop to 256 bytes, which should
+	protect us against even most RISC machines with large register
+	sets.
+	(locate_var_value):  Move declaration inside related ifdef.
+
+	* remote-nindy.c ():  Use TIOCSETN rather than TIOCSETP
+	throughout, to avoid throwing away buffered input from the board.
+	(nindy_wait):  Supply_register takes addr_of_value, not value.
+	(i960_print_fault):  Renamed from i80960_fault.
+	(nindy_fetch_registers):  Avoid have_regs stuff, just get them.
+	(nindy_store_registers):  Avoid regs_changed stuff, just stuff
+	them.
+	(nindy_create_inferior):  Don't bother to write PC_REGNUM since
+	we can set the PC in the call to proceed().  Unpush nindy_ops
+	before pushing it on top, to avoid message to user.  Eliminate
+	commentary from Unix machines that just misleads here.
+	(reset_command):  Fix error message to suggest target command.
+	
+Wed Dec 19 11:03:56 1990  John Gilmore  (gnu at cygint)
+
+	Release 3.92.5 as frozen.
+
+	Stabilize the merged release...with help from lint, Saber C,
+	gcc -W, etc.
+
+	Everywhere:  Add include files needed to declare return types
+	of functions called.
+
+	* gdb.texinfo:  Roland Pesch is documenting gdb, glory be!
+
+	* breakpoint.h:  Add undeclared breakpoint functions, and some
+	functions for display handling since I couldn't think of a better
+	.h to put them in.
+
+	* breakpoint.c (insert_breakpoints):  Make code for disabling
+	shared library bkpts more likely to work.  It's used when we
+	rerun a program and stop before the shared library has been
+	mapped in.
+	(breakpoint_cond_eval, bpstat_stop_status):  Pass arg as int,
+	cast from pointer, so it squeezes through catch_errors.
+	(bpstat_stop_status):  Fix logic broken some time ago.  We now
+	always create a bpstat if the stop address matches a breakpoint,
+	even if we don't stop there -- just like the old code used to do
+	before I got my fingers into it (sigh).
+	(breakpoint_1):  Print "ignore count" after "stop only if"
+	condition, since that's how it actually works.
+	(mention):  Handle watchpoints as well as breakpoints.
+	(watch_command):  use set_raw_breakpoint and mention to do most 
+	of the work (and initialize all the fields!).  Only pass one
+	arg to parse_c_expression, since that's all it takes.
+
+	* command.c (not_just_help_class_command):  Rename arg to args
+	since we ignore "unused argument" warnings on vars named "args".
+	inflow.c (child_terminal_info):  ditto.
+	infptrace.c (kill_inferior):  ditto
+	main.c (catch_errors, version_info, quit_command, pwd_command,
+	source_command, dump_me_command, editing_info,
+	set_history_size_command, set_history, show_history,
+	set_verbose): ditto
+	stack.c (locals_info):  ditto
+	target.c (target_files_info):  ditto
+	valprint.c (set_input_radix, set_output_radix):  ditto
+
+	* core.c:  Remove old variables for handling core and exec file
+	sections (data_start, data_end, stack_start, stack_end,
+	reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
+	text_end, exec_data_start, exec_data_end, text_offset,
+	exec_data_offset, data_offset, stack_offset).  They're
+	superseded the more general build_section_table and
+	xfer_memory.
+	(get_exec_file):  Mention the `file' command.
+	(read_memory_check):  Rename to memory_error, and only call it
+	in the case of an actual error.
+	(read_memory, write_memory):  call memory_error.
+	(core_fetch_registers):  Register section name is ".reg".
+
+	coredep.c:  Remove a bunch of crud now that all this file does
+	is pull the registers out of a core file.
+	(fetch_core_registers):  Rewrite to actually work, I hope.
+
+	dbxread.c:  Use a.out.gnu.h, not system a.out, now.
+	Replace index() with strchr().  Remove all the pre-BFD macro
+	definitions for accessing the symbol file.
+	(struct dbx_symfile_info):  Encapsulate the information that
+	dbx_symfile_init needs to pass to dbx_symfile_read in this
+	struct.
+
+	(dbx_new_init, dbx_symfile_init, dbx_symfile_read,
+	dbx_symfile_discard): Rearrange symbol file reading to divide
+	the format-specific part from the format-independent part,
+	leaving the format-independent part such as file name expansion
+	and opening in symtab.c.  This replaces
+	partial_symbol_file_open and partial_symbol_file_read.
+	Symbol_file_read, add_file, add_file_target_command,
+	add_file_addr_command move to symtab.c.  Pass an explicit
+	"mainline" flag for when reading the main symbol table, rather
+	than relying on the offset address to be zero or nonzero.
+
+	(dbx_symfile_read): Don't allow void *'s to be printed as
+	typedefs.
+	(SWAP_SYMBOL):  Use bfd routines to byte-swap the symbols.
+	(ADD_PSYMBOL_TO_LIST):  Make the "function call rather than
+	macro" debug version really work.
+	(read_dbx_symtab):  Remove unref'd parameter inclink.
+	Avoid swapping N_SLINE symbols, for speed.
+	Merge N_TEXT!N_EXT case with the other external symbol
+	definitions' case. Add comments.
+	(start_psymtab):  Allocate the symfile name in the psymtab on
+	the psymbol_obstack, rather than using the caller's storage.
+	(end_psymtab): Only allocate a dependencies list if there are
+	more than zero.
+	(psymtab_to_symtab_2):  Use BFD when reopening file to read
+	its symbols for real.
+	(read_struct_type):  Add FIXME comments where it needs work
+	for C++ bogosity.
+	(read_huge_number):  Add FIXME about overflows.
+	(read_range_type):  Add FIXME about comparing a long to 1<<32.
+
+	* coffread.c:  Minor changes to move things closer to the new
+	regime with symtab.c and dbxread.c   Major work is still needed
+	here.
+
+	* exec.c (exec_file_command):  Remove old variables (see core.c
+	above).
+	(xfer_memory): If memory transfer is right at the end of a
+	section, don't lose.
+
+	* findvar.c (get_saved_register):  If value is in a real
+	register, LVAL is lval_register, not lval_memory.
+
+	frame.h:  Declare print_sel_frame and record_selected_frame.
+
+	gdb-int.texinfo:  New file, for GDB internals documentation.
+	Very simple, unformatted doc of cleanups is there for now.
+
+	gdbcore.h:  Remove obsolete variables that described a.out
+	section addresses and offsets.  (See core.c above.)
+	Declare fetch_core_registers and registers_fetched.
+
+	getopt.c:  Declare char *alloca(); even on SPARC.
+
+	infcmd.c (run_command):  Call target_kill rather than
+	kill_inferior. 
+	(step_command, next_command, stepi_command, nexti_command):
+	Declare from_tty parameter even though we don't use it.
+	(run_stack_dummy):  argument BUFFER is a char array, not
+	a pointer to REGISTER_TYPE.
+	(finish_command):  using_struct_return needed a value *, 
+	not a struct symbol *.
+
+	* infptrace.c (child_xfer_memory):  To avoid dependency on
+	where sections are in memory, try PT_WRITE_D and if that fails,
+	try PT_WRITE_I.  Most Unixes don't care which you use.
+
+	* infrun.c (step_resume_break_shadow):  Change to array to
+	match other breakpoint shadow storage.
+	(clear_proceed_status):  Pass address of bpstat to
+	bpstat_clear, not the bpstat itself.
+	(child_create_inferior):  FIXME comment about if the child
+	exits.
+	(start_inferior):  Remove old function.
+	(child_open):  Use target_kill rather than kill_inferior.
+	(wait_for_inferior):  Ditto.
+	(insert_step_breakpoint, remote_step_breakpoint):  Use
+	new step_resume_break_shadow.
+
+	* inftarg.c (child_wait):  If all child processes die,
+	pretend that the one being waited for exited with signal 42.
+
+	* main.c (command_line_input):  When scanning for comments,
+	don't coredump on unclosed quotes.
+	(quit_command):  Use target_kill rther than kill_inferior.
+	(_initialize_main):  Rename class_user from "user" to
+	"user-defined".
+
+	* printcmd.c (print_command_1):  Initialize "fmt" if no format
+	is specified by the user.
+	(print_frame_args):  Only add to args_printed if we are
+	actually fetching args from the stack (avoiding undefined
+	arg_size).
+	(_initialize_printcmd):  Remove bogus \{ from string.
+
+	* remote-eb.c (eb_open):  Avoid coredump on no argument.
+
+	* remote-nindy.c:  Bring out of Intel environment into new
+	target environment.  Remove all conditional compilation on
+	I80960.  Massive hacking throughout.
+	(nindy_xfer_inferior_memory):  New routine stolen from
+	infptrace.c.
+	(nindy_create_inferior):  New routine pieced together, probably
+	not quite working yet.
+	(nindy_ops):  New target_ops struct for nindy.
+
+	* remote-vx.c:	Use write_memory rather than target_write_memory
+	to get error checking.
+	(vx_add_file_command, vx_open): Use symbol_file_add rather than
+	add_file.
+	(vx_create_inferior):  Use target_terminal_ours...
+
+	* signame.c (_initialize_signame):  Always initialize, since
+	we need the table for things other than psignal.
+	
+	* solib.c (solib_add):  Use symbol_file_add, not add_file.
+	(solib_address):  Return boolean result rather than struct
+	pointer which nobody else knows the type of.
+
+	* sparc-tdep.c, valops.c:  Use write_memory rather than
+	target_write_memory, to get error checking.
+
+	* stack.c (locals_info, catch_info, args_info,
+	get_selected_block, frame_command, up_command): Use
+	target_has_stack, rather than have_inferior_p or
+	have_core_file_p.
+
+	* sun3-xdep.c (fetch_core_registers):  Rewrite for new BFD regime.
+
+	* symfile.h:  New file, defining the interface between the
+	generic and object-file-specific symbol reading code.
+
+	* symtab.c:  Move generic symbol-reading interface to symtab.c,
+	from dbxread.c, coffread.c, mipsread.c, etc.  Add symtab_fns
+	table to map BFD targets to symbol-reading modules in GDB.
+	Change index to strchr.
+	(lookup_struct_elt_type):  Use error() rather than hand-made
+	simulations thereof.
+	(lookup_partial_symbol):  Speedup slightly when length == 0.
+	(symbol_file_add):  New function.
+	(symbol_file_command):  Call it.
+	(symfile_open, symfile_init):  New function.
+	(add_file_target_command, add_file_addr_command): moved from
+	dbxread.c.
+
+	* target.c (target_command):  use target_kill.
+
+	* target.h (target_files_info):  Don't declare, never called
+	from outside.
+
+	* tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
+	files to determine stack end address.
+
+	* valarith.c (value_x_binop, value_x_unop): Change error message
+	to be more useful.  Pass proper argument to value_struct_elt.
+
+	* valops.c (value_assign):  FIXME comment that long long 
+	bitfields will break here.
+
+	* Makefile.dist:  Add symfile.h, remote-nindy.c, remote-eb.c.
+	Update `make saber_gdb' to work better.
+
+	* TODO:  A woman's work is never done.
+
+	* cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
+	main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
+	remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
+	sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
+	target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
+	valops.c, valprint.c, exec.c:  Lint.
+
+
+Wed Dec 12 23:44:15 1990  John Gilmore  (gnu at cygnus.com)
+
+	Continuing Intel 960 port merge of GDB.
+
+	* Makefile.dist:  Merge i960 "nindy-share" files.  Rename
+	malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
+	Don't ship gdb.dvi in tar file.  Link gdb with init.o, not init.c.
+	Wack over "make depend" so it handles files in subdirectories
+	vx-share, nindy-share, bfd, and in the current directory.
+
+	* blockframe.c (get_prev_frame_info):  Remove fatal error
+	if stack not defined.
+
+	* core.c (core_open, core_detach):  New functions that handle
+	the old "core-file" command as "target core" and "detach" instead.
+	(core_file_command):  Call them.
+	(core_xfer_memory):  Use common routine xfer_memory.
+
+	* dbxread.c:  Include a.out.gnu.h, not system a.out.h.
+	dbxread now uses bfd for everything but symbol reading itself.
+	BFD internals are used to drag out the relevant file offsets.
+	(partial_symbol_file_open):  Change args all around for BFD.
+
+	* symtab.c: Rename "value" to "val" everywhere, so we can
+	#include "value.h".
+	(symbol_file_command):  New command, moved from dbxread.c
+	and coffread.c.  It uses BFD to read the file, then vectors
+	based on its type, to dbx or coff symbol readers.
+	* symtab.h:  Extern a few vars for symbol_file_command.
+
+	* target.h:  Breakpoint takes a char * save area, not a char **.
+
+	* valprint.c (val_print):  When unpacking bitfields, offset
+	the address in gdb of the value, if it is declared with a shorter
+	type.  Remove the last "runtime kludge test" of host byte order.
+
+	* utils.c:  Remove old my_bfd_read routine.
+
+	* stack.c (frame_info):  Use target_has_stack.  Print program counter
+	register's actual name rather than "pc", since it's called the
+	"ip" (instruction pointer) on the i960 (sigh).
+
+	* target.c (target_command):  Add command for selecting a target
+	type and calling its open routine.  This is used for initiating
+	communication with a particular target, in a generic way.
+
+	* tm-i960.h:  Update for modern gdb.  Remove semicolons from
+	various macros.  Handle reading struct return convention, and
+	error-out attempts to return structs with the "return" command.
+	Be sure gdb doesn't think we know how to call functions in the
+	inferior.
+
+	* i960-tdep.c:  Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
+	to i960_xxx in lower case.
+	(arg_address):  Circumvent errors due to LOC_ARG_BLOCK
+	not being defined yet.
+
+	* remote.c (remote_open):  Call start_remote to initialize 
+	wait_for_inferior during open.
+	(remote_xfer_inferior_memory):  Return length written rather
+	than errno value.
+
+	* remote-vx.c (target_command -> vx_open):  Use new generic
+	target command.
+	* remote-eb.c, inftarg.c, exec.c: ditto.
+
+	* infrun.c:  Fix comments.
+	(attach_program -> child_open):  Use new generic target command.
+	(wait_for_inferior):  Clear saved register values before target_wait,
+	so target_wait can set some of them if convenient.
+
+	* infptrace.c (fetch_inferior_registers, store_inferior_registers):
+	Return success indicator, not void.
+	(child_xfer_memory):  Avoid fetching initial word if we'll
+	overwrite it anyway.
+
+	* infcmd.c (attach_command):  Use new generic target open routine.
+	(_initialize_infcmd):  Update doc on attach and detach commands.
+	(do_registers_info):  Merge in a byte-order problem as a FIXME
+	comment.
+
+	* findvar.c (find_saved_register):  Avoid problem in current frame.
+	(read_relative_register):  Ditto.
+	(write_register):  Convert byte order on the way out.
+
+	* exec.c (file_command):  Add.
+	(add_to_section_table, exec_command):  Use new bfd_map_over_sections.
+	(xfer_memory):  Common function between core_xfer_memory and
+	exec_xfer_memory.
+	(exec_xfer_memory):  Use it.
+
+	* pn-opcode.h:  Document that a "PN" is a Gould PowerNode.
+
+	* breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
+	valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
+	infcmd.c, i960-pinsn.c, eval.c, defs.h:  lint and gcc -Wall.
+
+Sun Dec  2 16:45:06 1990  John Gilmore  (gnu at cygnus.com)
+
+	Merge Intel 960 port of gdb, continuing...
+
+	* dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
+	symbol_file_command):  Pass from_tty arg to hush 'em up.
+
+	* coffread.c (symbol_file_command):  Avoid output if from_tty != 1.
+	Add magic numbers for 960 COFF format.
+
+Fri Nov 30 09:18:20 1990  John Gilmore  (gnu at cygnus.com)
+
+	Merge Intel 960 port of gdb, from Intel "1.2" release.
+
+	CHANGE_LOG entries from their port, which was based on
+	gdb+-2.8.0:
+
+    Thu Sep  6 11:02:22 PDT 1990
+	Remove temp file if download is interrupted.
+
+    Wed Aug  1 09:08:33 PDT 1990
+	Now uses binary protocol to talk to NINDY.
+	Old hex protocol (NINDY 2.13 and older) supported with -O switch.
+	Times out after 5 seconds when trying to talk to NINDY.
+
+    Tue May 29 12:54:49 PDT 1990
+	Added variable baud rate (-b switch).
+	Source code reorganization.
+
+    Thu Apr 26 11:09:55 PDT 1990
+	More cleanup of batch mode;  specifically, execute "-s", "-e", and
+	"-se" switches as soon as they are encountered on the invocation line.
+
+    Fri Apr 20 13:47:15 PDT 1990
+	Add -brk switch.
+
+    Thu Apr 19 09:54:28 PDT 1990
+	Add 'reset' command.
+
+    Wed Apr 18 09:48:07 PDT 1990
+	After opening remote tty, wait for 1 second to go by without input
+	from it before trying to talk to NINDY (fixes problems with the
+	Heurikon HK80/V960E).
+
+    Mon Apr  4 16:33:05 PDT 1990
+	Some output was not being suppressed in 'batch' mode.
+
+    Thu Mar 22 15:31:11 PST 1990
+	Ask user if old symbol table should be deleted when new file is
+	downloaded.
+
+	Allow user to run a program downloaded before gdb960 was brought up.
+
+	Correct "exec-file" help message for i80960 context.
+
+	Correct bug in calculating user space address:  could occasionally
+	corrupt user program.
+
+	Make sure to zero low-order bits in rip's because of bug in 960CA
+	A-step part:  could cause operation faults when "next"ing across
+	a function call.
+
+	Correct bug that made it impossible to get source line numbers for
+	code loaded at addresses higher than 0x7fffffff.
+
+    Wed Jan 10 12:43:22 PST 1990
+	Open remote tty for exclusive use.
+
+    Fri Jan  5 12:14:42 PST 1990
+	Correct disassembly (CA manual was right after all):
+	opcode for sysctl is 0x659
+
+    Mon Oct 23 12:03:04 PDT 1989
+	Use G960BASE and G960BIN environment variables to find 'sx' utility.
+
+    Mon Oct 16 14:15:09 PDT 1989
+	"sfr0"-"sfr31" should have been named "sf0"-"sf31"
+
+    Mon Oct  2 15:56:31 PDT 1989
+
+	Added 960CA disassembly support.
+
+	To simplify maintenance:
+		- eliminated use of symblic links on pinsn.c: use i960-pinsn.c
+			directly instead.
+		- eliminated opcode.h: incorporates tables into i960-pinsn.c
+		- moved 960-specific routines from i960-pinsn.c to i960-md.c
+		- made disassembly interface identical to that in gdmp960.
+
+
+
+Wed Nov 28 21:32:48 1990  John Gilmore  (gnu at cygint)
+
+	* target.h: Allow targets to stack.  Add target_has_memory,
+	_registers, etc.  Restructure memory access and "info files"
+	to walk the target stack.
+	* exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
+	target.c:  Change tables to match target.h.

+	* infptrace.c (child_xfer_memory): New memory regime.
+	* inftarg.c (child_files_info): New "info files" regime.
+	* remote-eb.c: New memory regime, new info files.
+	* remote-vx.c: New memory regime, new info files.  Now use
+	separate targets for VxWorks attachment to machine, and 
+	actually running a process under VxWorks, since one has
+	stack & execution & regs and the other doesn't.
+	* remote.c: New memory regime, new info files.
+	* sparc-xdep.c (fetch_core-registers):  New memory regime.
+	* target.c:  New routines and support for stacked targets,
+	new memory regime, new info files regime.
+	
+
+	Generalize section handling for an arbitrary number of sections,
+	including use of the new BFD (binary file) library.
+	* gdbcore.h: Add struct section_table.
+	* exec.c (build_section_table):  Iterate all sections and
+	record what gdb needs to know about them.
+	(exec_command):  Use it.
+	(exec_xfer_memory):  Use the table.
+	(exec_files_info):  Print the table.
+	* core.c (core_file_command, core_xfer_memory, core_files_info):
+	Likewise.	
+	* source.c (find_source_lines):  Use bfd_get_mtime.

+	* utils.c (error):  Avoid using bfd_error in generic routines.
+	
+	* core.c (core_fetch_registers):  Get from the ".regs" section of
+	the BFD core file.
+	* sparc-xdep.c (fetch_core_registers):  Use the .regs info.
+

+
+Fri Nov 23 28:15:38 1990  John Gilmore  (gnu at cygint)
+
+	* breakpoint.c (bpstat_num):  Handle breakpoints which have

+
+	* TODO, Projects:  Lots more stuff to do...
+
+Fri Nov 23 18:15:38 1990  John Gilmore  (gnu at cygint)
+
+	Massive changes to wall off the remote-debugging interface
+	behind a function vector.  The port to handle VxWorks targets
+	is also part of this.
+
+	All files:  Replace references to renamed functions,
+	remove references to remote_debugging, remove references to
+	have_include_file, have_core_file in favor of target_has_stack,
+	target_has_memory, etc.
+
+	* Modularize the breakpoint interface.
+	breakpoint.h (BREAKPOINT_MAX):  New define sets max length of
+	a breakpoint instruction.
+	breakpoint.c: struct breakpoint's shadow_contents now sized as
+	BREAKPOINT_MAX.
+	(insert_breakpoints):  Vector to target to install breakpoints.
+	(remove_breakpoints):  Vector to target here too.
+	Remove REMOTE_SA_SPARC kludges and other remote_debugging.
+	sparc-tdep.c (single_step):  Use new breakpoint interface for
+	the single-step breakpoints.
+	mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
+	New file, contains routines to insert and remove breakpoints by
+	reading out the old contents and later replacing them.  This is
+	how ptrace breakpoints work, and many remote systems as well.
+
+	* tm-vxworks68.h:  New config file, overrides a few things for
+	Wind River's preferences.
+
+	* target.h:  New file, for transfer vector used to talk to the
+	inferior (child, attached, core, exec, remote, etc).  All accesses
+	to the thing being debugged should come through these vectors.
+	target.c:  New file, routines to handle transfer vector.
+	(various files):  Add transfer vectors XXX_ops for the various
+	targets and pseudo-targets (core files, etc) we support.
+
+	* breakpoint.c (bpstat_stop_status):  Further explorations of
+	watchpoints and why things don't work all the time.
+	(bpstat_alloc):  New fn to allocate a bpstat and chain it.
+
+	* config.gdb:  Only add "source ${srcdir}/.gdbinit" to
+	the local gdbinit if it doesn't already have it.
+
+	* core.c (core_ops):  add and install.
+	Allow core debugging without exec file.
+
+	* dbxread.c (free_and_init_header_files):  Merge two fns.
+	(end_symtab):  Free named symbol table when a new version comes in.
+	(read_dbx_symtab):  Relocate all kinds of symbols with base
+	address.  First step toward handling different text, data, bss
+	reloc.
+	(add_file_addr_command):  Renamed add_file_command.
+	(add_file_command):  Vector to remote handler.
+	Add "load" as an alias for "add-file" command.
+
+	* defs.h:  Allow "volatile" to be used in non-ANSI; use it for
+	non-returning functions.
+
+	* exec.c:  Add exec_ops, and push it as a target when an exec
+	file is specified.
+
+	* infcmd.c (run_command):  Pass executable file name and arg list
+	separately when starting an inferior.  Permit "run" when no exec
+	file is specified, for VxWorks.
+	(detach_command):  Move to child_detach in inftarg.c.
+
+	* inftarg.c:  New file.  Unix-child-specific routines, and the
+	child_ops structure.
+
+	* inferior.h (registers):  Export "registers" as the way for
+	target dependent register handlers to find gdb's local copy of
+	the registers.  Rename "stop_after_attach" to "stop_soon_quietly"
+	since it is now used by places that want wait_for_inferior to
+	handle the grunge but want to see every trap from the inferior.
+
+	* inflow.c (create_inferior):  Pull out, and merge into infrun.c.
+	Eliminate remote_debugging hooks in terminal handling.
+
+	* infrun.c:  Replace start_inferior with child_create_inferior.
+	Move all the hair of Unix shells and ptrace idiosyncracies into
+	child_create_inferior, so remote handlers don't have to deal.
+	Remove running_in_shell.  Rename stop_after_attach to
+	stop_soon_quietly, and use it in a few other places where we want
+	to just call wait_for_inferior and get control back on the first
+	trap.  trap_expected now never takes a value > 1.
+	(init_wait_for_inferior):  Initialize static vars when a new
+	process is created.
+
+	main.c (gdbinit):  Add new hook for .gdbinit file name, let
+	it be overridden by config files as GDBINIT_FILENAME.
+	(DEFAULT_PROMPT):  Add new hook for overriding (gdb) prompt.
+	Both of these are used for VxWorks gdb.
+
+	mcheck.c:  rename include file "gmalloc.c" to avoid problems
+	with system include file "malloc.c".
+
+	param-no-tm.h:  New include file, same as param.h but does not
+	include the default "tm.h" file.  This is used in files where
+	the target is known, e.g. remote-eb.c or sparc-xdep.c.
+
+	param.h:  Now just a shell that includes tm.h and param-no-tm.h.
+
+	remote-vx.c:  New file, VxWorks remote debugging support.  Uses
+	RPC routines that are shared with the target system, in directory
+	${srcdir}/vx-share.
+
+	remote.c:  Vectorize remote interface.
+
+	source.c:  Globalize source_path, and make an alias "l" for "list"
+	since we now have the "load" command.
+
+	sparc-xdep.c:  Use new param-no-tm.h.
+
+	symmisc.c (free_named_symtab):  Add new function from Wind River.
+	However, ifdef it out for now while we think about what it should
+	really be doing.
+
+	tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
+	PREPARE_TO_STORE to
+	the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
+	non-Unix-children handle this with their own code in the target
+	transfer vector.
+
+	Makefile.dist:  Roll version to 3.92.3.  Add vx-share stuff to
+	source and target lists.  Add vx-share to default list of include
+	directories.  Add new files to src and target lists: mem-break,
+	target, inftarg, remote-eb, remote-vx, targ-vx.  Be sure the
+	${srcdir} versions of munch and createtags are used.
+
+	* valops.c (find_function_addr):  Split out of call_function.
+	(call_function_by_hand):  Rename call_function; this function 
+	calls functions in the target by laboriously patching the target
+	word-by-word with the right stack, args, regs, etc.
+
+
+Mon Nov  5 17:29:10 1990  John Gilmore  (gnu at cygint)
+
+	Handle AMD 29000 a bit better.
+
+	* remote-eb.c (readchar):  Mask received char log to make it readable.
+	(remote_start):  Pass arguments down to executing program.
+	Make startaddr unsigned.
+	infrun.c (start_inferior):  Accept args, pass them to
+	remote_start.
+	infcmd.c (run_command):  Pass args down to start_inferior.
+
+	* tconfig/am29k-aout, tconfig/am29k-coff:  New files specifying
+	the target object file format.
+	tm-29k.h:  Pay heed to COFF_ENCAPSULATE.
+
+	* am29k-pinsn.c (print_insn):  Print 0x on hex numbers in disassembly.
+	am29k-tdep.c (examine_prologue):  Better checking of function prefixes.
+
+Sun Oct  7 18:20:45 1990  John Gilmore  (gnu at cygint)
+
+	* Makefile.dist (VERSION):  Roll version to 3.91.9 and freeze.
+	* TODO:  We did a few things, we have more to do though.
+
+	* xm-sparc.h (CLEAR_DEFERRED_STORES):  Define.
+	* inflow.c (inferior_died):  Clear deferred stores.
+	
+	* Debug problems with dummy frames and calls to the inferior.
+	* tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME):  Move to sparc-tdep.c.
+	* sparc-tdep.c (do_restore_insn):  Simplify.
+	(sparc_frame_find_saved_regs):  Simplify and fix what we find.
+	(sparc_push_dummy_frame):  Simplify and fix what we push.
+	(sparc_pop_frame):  Slightly more hair here, deciding whether
+	we are restoring a saved PC or returning to a return address in %i7.
+	* sparc-xdep.c (read_inferior_registers):  Debug if valid reg is read.
+
+	* utils.c (xmalloc, xrealloc):  Return type depends on __STDC__.
+	* symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
+	* obstack.h (chunkfun): ditto.
+	* defs.h (xmalloc, xrealloc): ditto
+
+	* utils.c (quit):  Grab the terminal from the child if necessary. 
+
+	* inflow.c (term_status_command): Rename to term_info, change
+	to "info terminal".
+
+	* sparc-pinsn.c (print_insn):  Disassembly prefers real instructions.
+	(is_delayed_branch):  Speed up.
+	* sparc-opcode.h: Add ALIAS bit to aliases.  Fix up opcode tables.
+	Still missing some float ops, and needs testing.
+
+	* Support for input and output radixes other than base 10
+	* defs.h (input_radix, output_radix):  Declare.
+	* expread.y (yyparse, parse_number):  Handle changes of input
+	radix, and ambiguous names-or-numbers in radixes >10.
+	* printcmd.c (print_scalar_formatted):  Print formatted hex
+	numbers in varying column widths.
+	* valprint.c (val_print):  Use output_format to print scalar ints.
+	(set_input_radix, set_output_radix, set_radix):  Create.
+	(set_output_radix):  Set output_format from output_radix.
+	(_initialize_valprint):  add `set radix' but leave the others off.
+	
+	* main.c (execute_command): Let stupid questions be turned off.
+	(_initialize_main): Handle "set stupidity", etc.
+
+	* main.c, inflow.c, inferior.h, frame.h, command.c, defs.h, 
+	sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c:  Lint.
+
+Tue Oct  2 11:20:02 1990  John Gilmore  (gnu at cygint)
+
+	* TODO, Makefile.dist, ChangeLog:  Freeze for 3.91.8 release.
+	bfd stuff is still screwed up, but with some manual work, it
+	compiles.
+
+	* breakpoint.c (bpstat_do_actions):  Start over if a command
+	proceeds the inferior, since the inferior will have stopped and
+	will need to have its new stop-actions taken care of.
+
+	* dbxread.c (read_struct_type):  Expression gives Sun3 4.0.3
+	compiler fits, simplify it.
+
+	* gdb.texinfo (directory command): Doc new dir command.
+	source.c (directory_command):  "dir" now puts things on the front
+	of the path, moves dups up front, and handles multiple names
+	on the command line, inserting each one in order.  It also
+	blows away cached line and full_filename info.
+
+	* stack.c (backtrace_command):  Skip "more stack frames follow"
+	unless interactive.
+
+	* Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
+	xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h, 
+	xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
+	The only odd one was Gould NP1, which had defined vprintf to
+	"printf"!!!
+
+	* Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
+	printcmd.c (print_command_1): Pass 'inspect' flag down as a global
+	variable, inspect_it.
+	valprint.c (print_string, val_print): Use the global inspect_it
+	to indicate whether to print in Epoch style or normal style.	
+
+Mon Oct  1 23:55:26 1990  John Gilmore  (gnu at cygint)
+
+	* printcmd.c (call_command):  add an alias for the "print" command
+	which runs expressions and doesn't print the result if void.
+	(print_command_1): implement it.
+
+	* command.c: Remove #if 0'd code.  Initialize all the fields
+	in add_cmd ().  Rename do_nothing_command to
+	not_just_help_class_command, and make it externally visible.
+	command.h: add user_commands to struct.
+	* main.c (define_command):  Don't overload c->function with a char
+	string as well as a function pointer.
+
+	* eval.c (evaluate_subexp):  Reinstall tiemann changes to
+	calling convention of value_struct_elt () that got dropped in
+	merge.
+
+	* tm-sparc.h (FRAME_FIND_SAVED_REGS):  move to sparc-xdep.c.
+	sparc-tdep.c (sparc_frame_find_saved_regs):  ditto.
+
+	* tm-sparc.h (POP_FRAME): replace some constants with defines.
+
+	* sparc-xdep.c (store_inferior_registers):  defer stores to regs
+	until a good time (e.g. when we are about to run the child),
+	saving ptrace calls.
+    	* infrun.c (proceed):  handle DO_DEFERRED_STORES.
+	* tm-sparc.h: define DO_DEFERRED_STORES.
+
+	* sparc-xdep.c (store_inferior_registers): when storing float
+	registers, don't store stack regs too.  When storing the SP,
+	however, DO store the stack regs too.  This fixes a bug in which
+	the dummy frame is not recognized when a call_function finishes,
+	because its frame pointer (in the stack regs) was never
+	initialized.
+	(read_inferior_registers):  Mark WIM and TBR and FPS and CPS valid
+	even though we don't know how to read them from an inferior.
+	valops.c (call_function):  Comment about storing SP.
+
+	* infrun.c (save_inferior_status): Save away the original bpstat
+	chain so it can be restored later.  Install the copied version for
+	use by whoever saved the status.  It will be blow away by
+	restore_inferior_status, and the original chain restored.  This is
+	important for people who have pointers into the original.
+
+	* breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
+	findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
+	main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
+
+
+Fri Sep 28 20:32:46 1990  John Gilmore  (gnu at cygnus.com)
+
+	* Makefile.dist: Roll version to 3.91.8.  Add bfd.h and bfdconfig.h
+	temporarily to the makefile.  Add am29k-opcode.h and WHATS.NEW.
+	Add stuff.c and kdb-start.c to the OTHERS list for tar files.
+
+Fri Sep 28 19:12:12 1990  John Gilmore  (gnu at cygint)
+
+	* Merge Mike Tiemann's multiple inheritance changes from Sun.
+	Store the baseclasses in a type struct starting from array element
+	0 rather than from the unusual array element 1.
+
+	dbxread.c: the above.
+	(virtual_context): Add
+	Read new debug information about which virtual function table
+	a virtual function is from, and store it in fn_field.fcontext.
+	
+	symtab.h: Add fcontextt.  Fix baseclass indices.  Typo in
+	TYPE_FN_FIELD_STATIC_P.
+
+	symtab.c: the above.
+	valops.c: the above.  Handle pointer casts of object *'s.
+	(search_struct_method): Add.
+	(value_struct_elt): First arg is now a pointer to a value, and is
+	modified on return.
+
+	valprint.c: the above.
+	values.c (value_virtual_fn_field): Add type arg.  Handle
+	offsetting to the proper object when calling virtual fns.
+	The above.
+	(baseclass_addr): Add valuep arg.
+
+	* README:  Document the current state of BFD config (missing).
+	* TODO, ChangeLog, Makefile.dist: Roll version.
+	* WHATS.NEW: Add summary of changes since 3.5.
+
+Thu Sep 27 16:23:12 1990  John Gilmore  (gnu at cygint)
+
+	* dbxread.c (read_struct_type): Clear bit vectors whenever
+	we allocate one.
+	symtab.c (B_CLRALL): define.
+
+	* tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
+	using == rather than =.  Huh...  This fixes the dreaded problem
+	wherein builtin_type_int becomes TYPE_CODE_FLT.
+
+	* core.c (info_files): Show the inferior pid.
+
+	* config.gdb: Avoid putting "dir" command into .gdbinit.  GDB
+	already knows how to look in the source directory.
+
+	* Remove psymtab hair from many places.  Remove duplicated code
+	for searching symbol tables.  Hide psymtabs from most places.
+	Make it fast to get from a psymtab to its symtab.
+
+	blockframe.c (blockvector_for_pc): Remove psymtab hair.
+	coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
+	mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
+	dbxread.c: export psymtab_to_symtab, make it work if called N times.
+	(psymtab_to_symtab): Rename to psymtab_to_symtab2.  Initialize
+	new symtab completely.  New psymtabs get symtab pointer
+	initialized to zero.  Remove MI warning printf.  
+	symtab.h: Comments.  Add psymtab to symtab pointer.
+	(PSYMTAB_TO_SYMTAB): New macro.
+	symtab.c: use PSYMTAB_TO_SYMTAB.  Add psymtab_to_symtab and export it.
+	source.c: use PSYMTAB_TO_SYMTAB.  Remove symtab version and
+	compilation fields.
+	stack.c (backtrace_command): Avoid pre-pass to read symbols, if
+	verbose is not set.
+	(print_frame_info): Avoid special-casing symbols that have not yet
+	been read in.
+
+	* source.c (open_source_file): Quick path if we have already
+	located the source file by its full name.
+
+	* symtab.c (lookup_symbol): Use find_pc_symtab rather than
+	find_pc_psymtab.  When a name is found in the misc function
+	vector, search the symbol table for its mangled name, not the
+	name that the user typed.
+
+	* bfd.h: Fix missing comment terminators, make #endifs match.
+
+	* valarith.c (value_less): Handle unsigned int comparisons.
+	Add FIXME about pointer compares, which assume host and target
+	pointers are the same.
+
+	* command.c (do_nothing_command): lint
+	dbxread.c: lint.  Remove sort_syms.  Document C++ visibility info,
+	fix comments on debug symbol format for visibility.  Actually set
+	visibility of symbols.
+	main.c (echo_command): lint; use <readline/history.h>.
+	tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
+	obstack.h (_obstack_blank): Rearrange pointer math to avoid
+	pointing past end of allocated memory; saber complains.
+	obstack.h: Declare the external functions that we use.
+	valarith.h: use <string.h>
+	solib.c (solib_add): lint.
+
+Fri Sep 21 17:05:19 1990  John Gilmore  (gnu at cygint)
+
+	* main.c (initialize_main):  Default info_verbose to off, now that
+	symbol reading is fast.
+	(quit_command):  Avoid clobbering exec_bfd while quitting.
+
+	* Initial BFD (binary file diddling library) merger:
+	coffread.c: Change AOUTHDR to struct exe_hdr.
+	dbxread.c: ditto.
+	core.c: initialize initialized data at compile time.
+	(core_file_command):  Move from coredep.c, convert to bfd.
+	(xfer_core_file): Convert to bfd.
+	exec.c (exec_file_command): use bfd routines.
+	gdbcore.h: BFD.
+	mips-tdep.c: Remove exec_file_command and friends.
+	source.c: bfd.
+	
+	* coredep.c: (fetch_core_registers) Convert core_file_command to
+	fetch_core_registers.
+	mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
+	
+	* utils.c: (error): Bogus crap, FIXME, to print bfd errors.
+	(my_bfd_read): More bogosity, which I don't think we call.
+	(program_name): Remove this atrocity asap!
+
+Wed Sep 19 13:36:41 1990  John Gilmore  (gnu at cygint)
+
+	* From Per Bothner:
+	values.c: allocate_repeat_value was not clearing the
+	optimized_out field.
+	(value_static_field): minor stylistic fix (wrong macro was used).
+	valops.c (value_struct_elt_for_address): didn't work for C++
+	static fields.
+
+	* signame.c (_initialize_signame):  Initialize signal names once.
+
+	* breakpoint.h, command.c, copying.awk, defs.h, environ.c,
+	exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
+	symtab.h, tm-29k.h, valprint.c, value.h, values.c:  Lint.
+
+	* remote-eb.c:  Support user-settable baud rates on the serial port.
+
+	* tm-sun3.h (PREPARE_TO_STORE): fix typo.
+
+Fri Sep 14 13:28:29 1990  John Gilmore  (gnu at cygint)
+
+	* tconfig/sun3os4: Remove warning about native assembler,
+	since it also occurs in the xconfig file.
+
+	* findvar.c (registers): Allocate some slop after `registers'
+	to prevent stray accesses from trashing the next variable.
+
+	* tm-68k.h (REGISTER_BYTES):  Allocate the right number of bytes
+	on the sun-3, by changing the #ifdef from `sun3' (which is not
+	defined by cc) to `sun'.  Symptom was trashed builtin_type_XXX
+	vars, which happened to follow `registers' in the executable.
+
+	* readline/history.c (history_search): Heed gcc-2's advice
+	and parenthesize && inside ||).
+
+	* am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
+	tm-29k.c:  Insert FSF copyright headers.
+
+	* remote-eb.c:  Better comments.
+
+	* Makefile.dist:  Update to 3.91.6.
+	* TODO: note PREPARE_TO_STORE problem.
+
+Thu Sep 13 09:52:33 1990  Jim Kingdon  (kingdon at cygint)
+
+	* stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
+
+	* remote.c:  Wrap the whole file in #if !defined (SPECIAL_REMOTE).
+
+	* infrun.c (wait_for_inferior, at end): Don't set up
+	prev_* if the inferior no longer exists.
+
+	* inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
+	CANNOT_EXECUTE_STACK.
+	valops.c (call_function): Use it.
+
+	* tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
+
+	* inferior.h (PC_IN_CALL_DUMMY): New macro.
+	infrun.c (wait_for_inferior, 2 places): Use it.
+
+	* values.c (value_being_returned): Only use
+	EXTRACT_STRUCT_VALUE_ADDRESS if defined.
+
+	* Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
+	right thing for remote-eb.c.  
+
+	* sun3-xdep.c:  Remove extraneous call to remote_store_registers.
+	* sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c:  Ditto.
+
+	* blockframe.c:  Put get_frame_saved_regs inside #if !defined
+	(FRAME_FIND_SAVED_REGS).
+
+	* findvar.c ({fetch,store}_registers): Check for
+	REMOTE_{FETCH_STORE}_REGISTER macro.
+
+	* findvar.c (get_saved_register): Add argument lval and
+	change meaning of argument addr.
+	findvar.c:  Change calls to get_saved_register to reflect
+	new calling convention.
+	valops.c (value_assign): Use get_saved_register instead of
+	find_saved_register.
+
+Sun Sep  2 12:40:20 1990  Jim Kingdon  (kingdon at cygint.cygnus.com)
+
+	* coffread.c (read_one_sym): Make temp_aux an AUXENT, not
+	an (uninitialized) pointer to one.  Use "&" when passing it
+	to fread.
+
+Fri Aug 31 22:57:54 1990  Jim Kingdon  (kingdon at cygint.cygnus.com)
+
+	* coffread.c (getfilename): Use DGUX x_offset and x_name if
+	defined.
+
+	* coffread.c (symbol_file_command): Put semicolon after
+	"int from_tty".
+	Put safe_to_init_tdesc_context in #if defined (TDESC).
+	Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
+	coffread.c: #include <sys/stat.h>.
+	(read_coff_symtab): Typo: in_source_files -> in_source_file.
+	Add missing ')' in check for "lc%" and friends.  Remove
+	extraneous '}'.
+	Declare read_one_sym() at top of file.
+	(read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
+	MC68WRMAGIC can have the same value without causing a duplicate
+	case.
+
+Thu Sep 13 15:55:36 1990  John Gilmore  (gnu at cygint)
+
+	* Allow a Makefile to be built without building the
+	tm and xm file links that screw up builds in subdirectories.
+	This is done with `config.gdb none', then you can do things
+	like `make gdb.tar.Z'.
+	* tconfig/none: Config file for no target system
+	* xconfig/none: Config file for no host system
+	* config.gdb: If no TM or XM files are called out by the
+	host or target file, don't make links for them.
+
+	* cplus-dem.c: Add documentation.
+
+	* dbxread.c (read_ofile_symtab): Turn a fatal error into a
+	simple error, so the user's gdb doesn't crash due to some object
+	file problem (e.g. somebody is rebuilding the file out from under
+	gdb).
+
+	* printcmd.c (print_address_symbolic): demangle the symbol.
+
+	* Makefile.dist (OTHERS): Remove tdesc-lib because it has 
+	Motorola copyrights in it.  Make "make gdb.tar.Z" work.
+	(alldeps.mak): sort and uniq all results from this; duplicates
+	hose gdb.tar.Z link building.  Remove RCS files from
+	tconfig and xconfig.  Add config files for sun386.  Add
+	a few odd files to OTHERS and HFILES.
+
+Mon Sep 10 21:20:24 1990  John Gilmore  (gnu at cygint)
+
+	* Makefile.dist: Pull solib.c to tconfig/sun?os4.
+	Roll version number to 3.91.5.  Make lint work in bindir.
+
+	* README:  Document cross-debugging and new file structure.
+
+	* blockframe.c: Lint.  Include "value.h" to declare read_register.
+	(find_pc_partial_function): remove duplicate line.
+
+	* command.h: Lint.  Declare error_no_arg and dont_repeat.
+
+	* tm-news.h: Remove inadvertently duplicated stuff.
+
+	* mipsread.c: Remove cache_pc_function stuff, now done cleanly.
+	Clean up usage of misc_function_type.  Declare some CORE_ADDRs.
+
+	* config.gdb: Allow `config.gdb host target' form.  Clean
+	up previous change that printed bogus messages when you just said
+	`config.gdb'.
+
+	* core.c: #include "command.h" for lint.
+	* dbxread.c: lint
+	* eval.c: lint
+	* main.c: Remove some casts of enums.  Lint.
+	* source.c: lint
+	* symtab.c: lint
+	* symtab.h: lint
+	* expread.y: lint
+	* valarith.c: lint
+
+	* printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
+	
+	* sparc-tdep.c (isannulled): Take instruction as parameter, don't
+	read it from memory.  This will allow us to save ptrace calls
+	eventually.   Changed caller single_step too.
+
+	* sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
+	that we aren't going to use, saving many ptrace calls, especially
+	when watchpointing or single stepping.  Use some #define's for
+	constants.
+	(store_inferior_registers): Ditto.
+	(core_file_command): Use some #define's for constants.
+
+	* tm-sparc.h: Add #define's for some register numbers, so we
+	can eliminate the use of random constants in sparc-xdep.c.
+
+	* stack.c (frame_command, print_frame_info, up_command,
+	down_command) Remove frame_changed, since it
+	causes a bug and doesn't seem to do anything useful.  In some
+	places it was used as a flag, in others as a stack level (?).
+
+	* utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
+	default is to use the portable (vprintf) version rather than the
+	kludge version.
+	* xm-news.h (MISSING_VPRINTF): Add.
+
+	* valprint.c (val_print): Demangle fancy vtbl printouts.  Lint.
+
+Sat Sep  8 00:24:12 1990  John Gilmore  (gnu at cygint)
+
+	* Remove stuff that forces -Bstatic linking of gdb, and warnings
+	about linking debugged programs -Bstatic in the sun?os4 config
+	files in tconfig and xconfig subdirectories.
+
+	* main.c (main):  Remove unreached exit(0) now that we exit
+	via quit_command().
+
+	* Create TODO file for online bug list.  There are too many
+	"little" bugs to keep track of on paper.
+
+	* Change Projects file to refer to bug-gdb@cygnus.com
+	rather than kingdon@ai.
+
+Fri Sep  7 23:35:15 1990  John Gilmore  (gnu at cygint)
+
+	* Makefile.dist (VERSION): 3.91.4 now.
+
+	* symtab.c (init_misc_bunches): Rename from init_misc_functions.
+	(condense_misc_bunches): Add sanity check that misc_count is
+	the same as the number of symbols in the bunch.
+	
+	* coffread.c: rename init_misc_bunches.  Pass an argument 
+	to condense_misc_bunches (a zero).
+
+	* dbxread.c (partial_symbol_file_read): Call init_misc_bunches
+	every time we are called; don't rely on our caller to do it.
+	(add_file): Remove call to init_misc_bunches.
+
+	* mipsread.c: Only warn, don't error, if unknown symbol types.
+	This keeps an old gdb from falling on its face if it sees newly
+	extended symbol info.  Rename init_misc_bunches.
+
+Fri Sep  7 22:58:15 1990  John Gilmore  (gnu at cygint)
+
+	* Merge in changes from Per Bothner for DECstations and other
+	MIPS stuff.  The rest is Bothner speaking:
+
+	The next message is a merger of Alessando Forin's mips port with
+	mine.  I've tried to use my good if biased judgment to get
+	the best of both. It *does* need testing.
+
+	Some of the changes are general, *not* mips-specific.
+
+	param.h:
+	Didn't believe in little-endian bit order.
+	There are still inconsistencies about whether flags
+	like BITS_BIG_ENDIAN are integer (#if ...) or
+	boolean (#ifdef ...). I tried to paper over them.
+
+	dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
+	Moved some misc_function code that was common to
+	{dbx,coff,mips}read.c to symtab.c.
+	In the process, I think I cleaned things up a bit.
+	At the same time, moved obsavestring and obconcat to symtab.c.
+
+	dbxread.c:
+	Removed obsolete condense_addl_misc_bunches (use
+	condense_misc_bunches(1) instead).
+
+	exec.c:
+	Needed to include <sys/dir>, at least on DECstations.
+
+	valops.c, mips-tdep.c, tm-mips.h:
+	Added PUSH_ARGUMENTS macro to support funny argument-pushing
+	conventions (when STACK_ALIGN is insufficient).
+	Needed on mips, where doubles need 8-byte alignment,
+	but ints only need 4.
+
+	mips-opcode.h:
+	Removed cruft that was not being used.
+	Merged in many fixes (most from Frank Yellin, fy@lucid.com).
+
+	mips-pinsn.c:
+	Print $ before register-names (I think that makes things a little
+	more consistent).
+	Never print two instructions, even if one delays.
+	Removed hex-disassemble set_cmd.  (This is not mips-specific,
+	so I think the argument is whether it is generally worthwhile or not.
+	I'm inclined to think not, given how easy it is to
+	convert between radixes in gdb.)
+
+	mipsread.c:
+	This is basically Alessando's code.
+	It doesn't use obstacks; I changed it to use obstacks
+	in a few minor places where using malloc causes a
+	memory leak. (Probably, more places could/should be changed.)
+	I added record_misc_function where it was missing.
+	In symbol_file_command and add_file_command, I tried
+	to make the code consistent with more recent versions.
+	Minor sylistic changes in parse_procedure.
+	Make a .gdbinfo. psuedo-symbol point back to the real
+	procedure symbol (using the isym field).
+
+	mips-tdep.c:
+	This is basically from my port, but with a lot of details
+	and a number of routines merged in from Alessando's version.
+	I basically used my code "raw" backtrace (use heuristics
+	from the actual code, rather than symbol table info) - though
+	the idea is Alessandro's. I feel my code is a little cleaner
+	here, particularly in being a little more flexible, such as being
+	able to handle gcc-produced code (which it now can).
+	It also doesn't do frame caching (which is not useful
+	more recent gdb versions).
+	I also used my code for push_/pop_dummy, more or less.
+	I tried to incorporate AF's code for testing sigtramp
+	while backtracing; I probably got it wrong.
+	Added mips_print_register, which tries to scrunch as much
+	information as possible on a screen...
+	Removed the skip-prologue set_cmd. As with hex-disassemble (see
+	under mips-pinsn.c), I don't see anything mips-specific here,
+	and I don't see it being all that useful anyway.
+	
+	tm-mips.h:
+	Added a $fp psuedo-reg distinct from $fp (nice for gcc).
+	Use more register names (rather than hard-cases numbers).
+	
+Thu Sep  6 18:33:15 1990  John Gilmore  (gnu at cygint)
+
+	* Hack up 3.90.11 changes:
+
+	* Makefile.dist (depend): parameterize $(GCC).
+	Add solib.c and solib.o.
+	(readline): Fix vpath for both absolute or relative SRCDIR.
+
+	* blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
+	Also, let the part I didn't understand at least compile so
+	I can test the rest.  FIXME.
+
+	* dbxread.c: Fix thinko using strcmp.
+	(init_psymbol_list): declare static.
+	(partial_symbol_file_open): Comment cleanups better, avoid
+	cleaning up the string table since the caller will do that.
+	Move the stat for mod time into symbol_file_command, temporarily.
+	(There should be a mod time for each symbol file, eventually,
+	to control its rereading.  FIXME.)
+
+	* infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
+	SunOS, which gives error for shared libs otherwise.  (From
+	Schaefer, probably FIXME needs work for portability.)
+
+	* solib.c:  Move #include "param.h" to work.
+	Lowercase all the Uppercase Letters In the Messages.
+	(find_solib): Clean up inferior_so_name for debug printouts.
+	Allow no argument, to mean all shared libraries.
+
+	* symmisc.c: include param.h to get CLEAR_SOLIB.	
+

+Sat May  5 12:39:18 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)
+
+	* Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
+	VPATH to readline.
+	config.gdb: If srcdir != ., create readline directory and
+	copy a makefile into it.
+
+	* wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
+	consistency with POSIX.
+
+	* breakpoint.c (bpstat_stop_status): Disable watchpoint
+	when we exit its exp_valid_block.
+
+Tue Sep  4 11:46:46 1990  John Gilmore  (gnu at cygint)
+
+	* Makefile.dist: Bump version to 3.91.3.
+
+	* Clean up handling of breakpoint commands (somewhat).
+	  Prompted by Tiemann bug report "cont 10" doesn't work any more.
+
+	  inferior.h: Add breakpoint_proceeded to inferior status struct
+	  and globals; save it and restore it.
+	  (clear_breakpoint_commands): Cleanup, remove old #define.
+
+	  infrun.c (clear_proceed_status): Set breakpoint_proceeded.
+	  (save_inferior_status, restore_inferior_status): handle it also.
+	  (proceed): Remove earlier code that set breakpoint_proceeded.
+	  It is now set only in clear_proceed_status.
+	  (clear_proceed_status): Cleanup, use bpstat_clear rather
+	  than clear_breakpoint_commands.  No callers need the stop_bpstat
+	  between clear_proceed_status and proceed.
+
+	  infcmd.c: Add breakpoint_proceeded definition and comment.
+	  (cont_command, jump_command, signal_command): Move call to
+	  clear_proceed_status right next to call to proceed.
+
+	  breakpoint.c (bpstat_do_actions): Avoid clobbering our
+	  caller's argument while running down the chain of breakpoints.
+	  Use new variable "breakpoint_proceeded" to determine when
+	  a command that it executes moves the inferior past the
+	  breakpoint.
+	  (bpstat_clear): Handle NULL argument.
+	  (bpstat_clear_actions): Avoid useless call to
+	  breakpoint_auto_delete.
+	  (delete_breakpoint):  Clean up bpstat's that are pointing to
+	  the deleted breakpoint from the stop_bpstat chain.
+	  (breakpoint_auto_delete): Simplify.
+
+	* Clean up handling of EOF, error on stdin, etc.  This was
+	  prompted by a network problem that caused gdb to go into an
+	  infinite loop filling up its malloc'd memory.
+
+	  main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
+	  not clear_breakpoints_commands, which is now gone.
+	  (main): If command_loop returns (e.g. from EOF on stdin), do
+	  a quit_command (looping back to command_loop if quit_command
+	  doesn't really quit).
+	  (command_loop): check result from command_line_input and
+	  exit if it returns NULL, rather than passing the NULL to
+	  execute_command.
+	  (gdb_readline):  Free malloc'd result space before returning
+	  NULL for EOF.
+
+	* utils.c (query): Handle C-d to mean "yes", just as if the
+	  input was not a terminal.  Also avoid infinite loop if EOF
+	  occurs in mid-input-line before newline.  This allows
+	  query to be used at EOF on stdin with reasonable results.
+
+	* infrun.c (proceed): Set breakpoint_proceeded.
+
+	* values.c (value_as_long): Avoid infinite recursion for enums.
+	  (_initialize_values): Fix typo in help msg (kingdon).
+
+	* Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
+	  RL_LIB for linking.  This allows -lreadline for linking
+	  and nothing for dependencies, once readline is a real library.
+
+	* config.gdb: Jim Kingdon: give useful error message if the
+	  host or target type is not recognized.
+
+	* defs.h (alloca): SPARC <alloca.h> does not declare alloca,
+	  it just defines it.  Dumb, but deal with it.
+
+	* Jim Kingdon suggests:
+	  in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
+
+Wed Aug 29 18:03:27 1990  John Gilmore  (gnu at cygint)
+
+	* Makefile.dist (VERSION): Bump version # to 3.91.2.
+
+	* Clean up Bothner's changes.
+
+	* blockframe.c (clear_pc_function_cache): New function.
+	* blockframe.c: remake cache_pc_function_* static.
+	* dbxread.c (symbol_file_command): remove references to
+		    cache_pc_function_* variables.
+	* dbxread.c (read_struct_type): Use VOFFSET_STATIC.
+	* printcmd.c: Avoid kludging a global variable (addressprint)
+	  to avoid printing the address of a string twice.  Instead,
+	  pass the format letter 's' down low enough that it can be seen
+	  to avoid this problem.
+	  (print_formatted): Pass format arg to value_print.
+	  (restore_addressprint): Remove function.
+	  (do_examine):  Avoid hacking addressprint, cleanups and such.
+	  (print_frame_args):  Add a comment to a Bothner change.
+	* symtab.h: define VOFFSET_STATIC and use it instead of "-1".
+	* symmisc.c (free_all_symtabs): Call clear_pc_function_cache
+	  to wipe out the values cached in blockframe.c.
+	* symtab.c (find_method): Add comment saying how big you must
+	  allocate to be "big enough".  Per being terse again.
+	* valprint.c (val_print): Handle format letter "s" to print
+	  strings without addresses.  Add comment to vtbl printing code
+	  which casts with wild abandon.  Rearrange reference-printing
+	  code so it prints:
+	       @0xaddr: value		(print w/addressprint)
+	       value			(print w/~addressprint)
+	       @0xaddr			(parameter lists w/addressprint)
+	  or   nothing			(parameter lists w/o addressprint)
+
+Tue Aug 28 10:47:18 1990  John Gilmore  (gnu at cygint)
+
+	* Merge more changes from Per Bothner:
+
+Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
+annoying) that I tried to improve it. Here are my suggestions.
+
+	These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
+
+	findvar.c:
+	Do automatic de-reference when taking the address of a reference.
+	printcmd.c:
+	Don't deref_ref when printing parameter lists.
+	valops.c:
+	More attempts at treating refernences properly.
+	valprint.c:
+	In val_print, if deref_ref==0, don't print dangling " = ".
+	value.h:
+	Add COERCE_REF macro, which de-references an REF.
+
+	* Merge changes from Per Bothner:
+
+* Fixed (Sony news)-specific configuration problems.
+* Fixed other problems with using vanilla pcc and libc (enum problems;
+assumption that vsprintf exists).
+* Some major speed-ups (finc_pc_partial_function now caches a match;
+parsing avoids duplicate symbol_lookup calls).
+* Changed handling of baseclasses (no longer use baseclasses field
+of struct type, use the first n_baseclasses fields instead).
+* Various minor changes/fixes, most C++-related.
+
+blockframe.c:
+Cache the most previous match from find_pc_partial_function.
+(Save both low and high ends of matching function's pc range.)
+This speeds up the loop of infrun.c:wait_for_inferior quite
+a bit, and makes step/next commands much zippier.
+command.c:
+Added an enum->int cast (otherwise, some compilers barf).
+dbxread.c:
+No longer set baseclass offset to 0, since multiple
+inheritance now mostly works.
+Added a number of casts, to shut up compiler warnings
+(after stabs where made enums, not ints).
+When discarding a symbol table (in symbol_file_command),
+must clear the cache introduced in blockframe.c.
+Don't convert $vtbl_ptr_type to vtbl any more.
+Get rid of TYPE_BASECLASEES and  baseclass_vec (see also symtab.h).
+Mask off sign bit emitted by g++ for virtual table offset.
+Set voffset to -1 (not 1) for static member functions.
+expread.y:
+Changed parsing/lexing of names to avoid doing symbol lookup twice
+(once when lexing to determine symbol class, once for real).
+Now only call symbol_lookup once. Fields of 'this' win especially big.
+printcmd.c:
+Subpress printing addr twice in the case of 'x/s addr'.
+symtab.c:
+lookup_basetype_type is no longer used.
+Add find_methods as recursive helper function to decode_line_1.
+This allows multiple inheritance to work.
+Also, once one or more matches has been found, do not look in
+base-classes. (Baseclass methods would be overridden, anyway.)
+symtab.h:
+Removed baseclasses array in struct type.
+Instead of using baseclasses[i], use fields[i-1].
+Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
+Changed sign convention of voffset (previous was inconsistent).
+tm-news.h:
+Some macros (CALL_DUMMY and relatives) were missing. Put them back.
+utils.c:
+Used to assume existence of vsprintf. Re-written to not need it
+if HAVE_VPRINTF is undefined.
+valops.c:
+typecmp was too pessimistic. Made it less so.
+valprint.c:
+Don't print space after address.
+If vtable points to a misc symbol (with 0 offset), print it,
+since that indicates the actual class of the object.
+Changed ype_print_derivation_info to use new inheritance
+scheme (without baseclasses vector).
+values.c:
+In value_primitive_field, fixed some bugs left over from previous set of fixes.
+Also, changes needed because TYPE_BASECLASSES were removed.
+xm-news.h:
+REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
+
+Tue Aug 21 20:08:54 1990  John Gilmore  (gnu at cygint)
+
+	* source.c:
+  If there is no path set, and the symbols don't indicate what directory
+  a file was compiled in, look in the current directory.  But either
+  a path or a known compilation directory will prevent this.
+
+	* dbxread.c:
+  Three independent bug fixes:
+   * Remove the #if 0 block that breaks some stuff.
+   * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
+     adapt gdb to either SunOS 4.0.* or 4.1.
+   * MAX_OF_TYPE and MIN_OF_TYPE thinko.  By tedg@sun, I think.
+ 
+	* symtab.c:
+  Instantiate the class T when looking for methods in it.  (Tiemann@sun)
+
+	* valprint.c:
+  (type_print) Demangle the name being printed.
+  (type_print_base) Handle botched demangling without coredump (tiemann).
+
+	* values.c:
+  (check_stub_method):  Document routine.
+			(tiemann) fix bug for no-arg functions
+			Avoid clobbering beyond end of malloc'd storage.
+			Terminate the argument list properly.
+
+Sat Aug 18 01:29:59 1990  Per Bothner (bothner@cs.wisc.edu)
+
+	* Changes merged by John Gilmore:
+    
+breakpoint.c:
+  In breakpoint_1, use new print_address_symbolic instead
+  of find_pc_partial_function. (This forces use of assembler-level
+  addresses, and avoids misleading non-mangled source-level names.)
+cplus-dem.c:
+  Generalize ansi argument such that -1 means skip arglist totally.
+  Removed global variable print_ansi_qualifiers (which made
+  code non-reentrant), in favor of extra explicit arguments
+  to internal routines.
+printcmd.c:
+  Add new helper function print_address_symbolic.
+  Use find_pc_misc_function instead of find_pc_partial_function
+  (since we want assembler-level symbols here).
+stack.c:
+  Print unknown function as just "f (...)", not "f (...) (...)".
+  Use new fputs_demangled explicitly.
+symtab.c:
+  Fixed a typing violation (problem: value.h cannot be imported
+  without renaming many variable in this file).
+  lookup_symbol: If no matching misc_func, look for a C++-mangled name.
+  decode_line_1: Moved forward some never-reached code.
+  Made decode_line_2 skip function prologues correctly.
+utils.c:
+  fputs_filtered should not demangle by default.
+  Add new fputs_demangled to demangle on demand..
+valops.c:
+  Change value_struct_elt to use value_primitive_field (using recursive
+  utility function search_struct_field). This allows foo.bar to work
+  for multiple inheritance (so far only for data fields).
+  Change check_field in the same way (recursive helper function
+  to support multiple inheritance).
+  (Note: there are more of these problems that I haven't fixed.
+  Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
+  value_of_this: 'this' symbol name is now just "this", note "$this".
+valprint.c:
+  Don't print static members.
+  Avoid printing "members of <type>" if there are none.
+  Simplified type_print_derivation_info by merging duplicate code.
+  Remove useless blank lines in type_print_base (ptype command).
+value.h:
+  Added declaration of new routine value_primitive_field.
+values.c:
+  Added value_primitive_field which is generalized version of
+  value_field that can handle multiple inheritance (non-zero offsets etc).
+  Re-implemented value_field to call value_primitive_field.
+
+Fri Aug 17 23:33:44 1990  John Gilmore  (gnu at cygint)
+
+	* infcmd.c -- insert else to avoid 'delete env' coredump when you
+	delete the whole environment.  Karl Berry reported the bug.
+	* source.c - fix openp to avoid //'s in filenames, which
+	trigger an Emacs bug causing it to not be able to find files
+	when running gdb in a window.
+	* dbxread.c - zap the #if 0 that botches the add-file code.
+	It seems to work a lot better without all the code commented out.
+
+Fri Jul 20 16:58:46 1990  John Gilmore  (gnu at cygnus.com)
+
+	* Merge Tiemann's and Ted Goldstein's changes, detailed below,
+	into gdb-3.90.9.
+
+Tue Jul 17 19:34:33 1990  Ted Goldstein  (tedg at golem)
+
+	* Makefile - added a ${CFLAGS} to a couple of entries,
+	added remote-sa.sparc.c
+	* added remote.sa-sparc.c, a modification of remote.c
+	which conducts a dialog directly with the SparcStation prom.
+	* breakpoint.c, infrun.c, sparcdep.c  added 
+	remote_insert_breakpoint(), and remote_remove_breakpoint() 
+	to breakpoint.c instead of directly writing breakpoint instructions.
+	* sparcdep.c on remote_debugging,there is no need 
+	to remove signle step breakpoint instructions.
+	* main.c added "-epoch" flag and "int epoch_interface" to main.c
+	global variable
+	* printcmd.c - epoch interface sends lisp expressions to open up
+	epoch windows on inspection.
+	* valprint.c - added arrayprint, and addressprint and made adding
+	format controls easier
+	* wait.h added a couple of undef's because we were getting
+	complaints about WSTOPSIG and WTERMSIG begin redefined.
+
+
+Wed Jul  4 05:27:51 1990  Michael Tiemann  (tiemann at masham)
+
+	* symtab.c (decode_line_1): Add support for handling method stubs
+	in the type information.

+
+	* values.c (baseclass_addr): Run loop from INDEX+1 to
+	N_BASECLASSES; otherwise, we can still get into a loop.
+	@@ This should be restructured to use a cleaner search strategy.
+
+Sun Jul  1 12:28:51 1990  Michael Tiemann  (tiemann at masham)
+
+	* dbxread.c (define_symbol,read_type): Grok GNU C++'s new
+	abbreviation "Tt" for tags which have the same name as their
+	typedecls.

+
+	* symtab.c (list_symbols): add ability to set breakpoints on all
+	the functions which match a particular regular expression.
+
+Tue Jun 26 04:26:29 1990  Michael Tiemann  (tiemann at masham)
+
+	* cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
+	should print ANSI qualifiers (such as `const' and `volatile').
+	All callers changed to call with ANSI == 1, except from
+	`check_method_stub', which uses old-style syntax.
+
+	* symseg.h (struct fn_field): Remove unneccessary `args' field.
+	* symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
+
+	* values.c (check_stub_method): New function.
+
+	* cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
+
+	* dbxread.c (read_type): Handle new GNU C++ method type stubs.
+	* valprint (type_print_base): Ditto.
+
+	* symtab.c (gdb_mangle_typename): New function.
+
+Tue Jun  5 00:18:43 1990  Michael Tiemann  (tiemann at gzilla)
+
+	* breakpoint.c (catch_command): New function.  Provides a
+	mechanism to set breakpoints based on catch clauses.
+	(disable_catch): Similar, but disables breakpoints on catch
+	clauses.
+	(delete_catch): Similar, but deleted breakpoints on catch clauses.
+
+Sun Jun  3 22:54:08 1990  Michael Tiemann  (tiemann at gzilla)
+
+	* blockframe.c (blockvector_for_pc): New function.
+	* blockframe.c (block_for_pc): Changed to call
+	`blockvector_for_pc' and get the block itself.
+
+	* stack.c (catch_info): New function.  Prints info about
+	exceptions which can be caught in the current frame.
+	* stack.c (print_frame_label_vars): New function.  Similar to
+	`print_frame_local_vars'.
+	* stack.c (print_block_frame_labels): Prints out labels that are
+	defined in this frame.  These labels are exceptions that can be
+	caught.
+
+	* dbxread.c: Updated to handle N_CATCH symtab types.
+
+Thu May  3 22:10:00 1990  Michael Tiemann  (tiemann at teacake)
+
+	* valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
+	form "struct ..." for GNU C++.  Don't flush any part of TYPE_NAME
+	when printing the type.
+
+Wed May  2 22:43:04 1990  Michael Tiemann  (tiemann at teacake)
+
+	* valprint.c (val_print): Use `baseclass_addr' to access the
+	baseclasses pointed to via the derived class object at VALADDR.
+
+	* values.c (baseclass_addr): New function.  Casts derived pointers
+	to baseclass pointers taking virtual baseclasses and multiple
+	inheritance into account.
+
+Sat May  5 12:39:18 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)
+
+	* Version 3.90.9.
+
+Fri May  4 12:12:55 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)
+
+	* breakpoint.c (watch_command, bpstat_stop_status): Deal with
+	exp_valid_block field correctly.
+
+	* infrun.c (wait_for_inferior): When checking "don't even think
+	about breakpoints" if stop_signal == SIGTRAP && trap_expected,
+	also check step_resume_breakpoint.
+	Insert breakpoints and continue (not step) if
+	step_resume_break_address != NULL, even if another_trap.
+	If trap_expected and we enter sigtramp, then set up a
+	step_resume_break.
+	If trap_expected is set when we hit the step_resume_break,
+	set another_trap.
+	When calling resume and trap_expected says tell resume to step
+	(2 places), also check step_resume_break_address.
+
+	* infrun.c (wait_for_inferior): Don't set
+	prev_{pc,sp,func_{start,name}} before calling wait ().
+	Do set them after exiting loop.
+	Move their declarations outside functions.

+
+	* infrun.c (wait_for_inferior, after check for trap_expected > 1):
+	Restore old code which distinguishes between trap_expected and
+	running_in_shell, just make the latter take any non-TRAP signal,
+	not just SEGV.
+
+	* values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
+

+
+	* breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
+	execute_command, exit both loops.
+
+	* Makefile.dist: Don't set TARGET_ARCH.  Add .c.o rule.

+
+	* valops.c (value_struct_elt), values.c (value_static_field):
