Thu Nov  7 18:26:15 1991  Steve Chamberlain  (sac at rtl.cygnus.com)

	* Makefile.in: link with libiberty after libreadline, since
	readline might want something in libiberty.
	* m88k-xdep.c: Fixed the register offsets in the ptrace_user
	struct for BCS 88k machines.
	* xm-m88k.h: don't define USIZE if already defined.
	* configure.in: Added delta88 target.

Thu Nov  7 04:51:19 1991  John Gilmore  (gnu at cygnus.com)

	* am29k-pinsn.c, am29k-opcode.h:  Fix decoding of mtacc, dmac, fmac.

	* tm-*.h:  Remove READ_DBX_FORMAT, COFF_FORMAT, and
	READ_MIPS_FORMAT, which have been unused since BFD.  Still
	remaining is COFF_NO_LONG_FILE_NAMES.
	* tm-sun3.h, tm-altos.h:  Remove detritus accidentally left from
	function calling code moved to m68k-tdep.c.

Wed Nov  6 17:21:59 1991  John Gilmore  (gnu at cygnus.com)

	* coffread.c:  Eliminate c_nsyms in favor of c_naux.
	Complain if no auxents on .bf and .ef FCN symbols, and assume
	lots of line numbers.
	(init_linenos, enter_linenos):  Use a sentinel at the end of the
	read-in linenos, to make for a fast, safe loop-end test.

Wed Nov  6 02:54:08 1991  Steve Chamberlain  (sac at cygnus.com)

	* coffread.c (read_coff_symtab): coffread used to rely on the
	x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
	function. Two of the formats I'm using (29k and 88k) don't seem to
	set it. Ths patch to fcn_last_line and (enter_linenos) is an
	attempt to use the actual size of the linno table in the file to set
	the number of linenos to process.

Tue Nov  5 22:47:46 1991  Steve Chamberlain  (sac at cygnus.com)

	* Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
	mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
	are created in place, so the mv fails, then the make continues.

Tue Nov  5 16:47:47 1991  Per Bothner  (bothner at cygnus.com)

	Add C++ as a separate language.
	* defs.h (enum language): Add language_cplus.
	* dwarfread.c (end_symtab):  Support language_cplus.
	* c-exp.y:  Add new struct language_defn cplus_language_defn.
	Don't set c to be the default language (see main.c).
	* c-exp.y (yylex):  Only look for field of this if
	language is C++.  (First difference from C!)
	* language.c:  Add case branches for C++ (currently, all
	the same as C).  Also, add c++ to "usage" note for "set lang".
	* valprint.c (typedef_print).  Add case branches for C++. 
	* main.c (main):  New way to set initial language:  Look at
	file extension of psymtab containing main().  (Same as we
	do for symtabs, but avoid loading the symtab yet.)
	* symtab.c: New routine find_main_psymtab(), used by main()
	to set initial language.
	* symfile.c (allocate_symtab):  Move code for mapping file
	extensions-> languages to new deduce_language_from_filename().

	Fix a C++ problem when looking for methods in super-classes.
	There was confusion between base and derived types.
	* valops.c (value_fn_field):  Change function interface.
	* values.c:  Use new value_fn_field interface.

Mon Nov  4 10:49:33 1991  Per Bothner  (bothner at cygnus.com)

	* infrun.c:  Fixed typo in comment.
	* utils.c:  All the v*fprintf emulation is now in libiberty,
	so we can get rid of some junk.
	* xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
	xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
	* m68k-pinsn.c (print_insn_arg):  Support BB/BW/BL
	type operands, as used by branch instructions.
	* gmalloc.c: Fix prototype of memcpy.
	* elfread.c: Comment out register_addr, since it conflicts
	with the one in coredep.c.
	* buildsym.h:  Remove extern declarations of two functions
	that are really static in buildsym.c.
	* tm-mips.h: Add symbolic names for more registers.
	* mips-xdep.c (store_inferior_registers): Use new register names.
	* xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
	only used for core files, not ptrace.  Therefore,
	the KERNEL_U_ADDR hack is no longer needed.
	The mapping to ptrace number is now in in mips-xdep.c.
	* mips-xdep.c:  Define REGISTER_PTRACE_ADDR (using the
	mapping from the old REGISTER_U_ADDR), and use it
	in {fetch,store}_inferior_registers.
	* mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
	* mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
	Save/restore FP regs correctly (?).
	* dbxread.c: Remove duplicate define_symbol and type_synonym_name
	(these had been previously moved to buildsym.c).
	Hence, define_symbol becomes extern instead of static.
	* buildsym.c (read_struct_type):  Comment out bogus handling
	of C++ operator methods.  Minor hacking of reading of class
	contexts. Make define_symbol non-static, so dbxread.c can call it.

Fri Nov  1 11:05:47 1991  John Gilmore  (gnu at cygnus.com)

	* mipsread.c (read_mips_symtab, read_the_mips_symtab):  Use real
	filename with error messages.
	* stack.c (frame_select_command):  Rename to select_frame_command
	to avoid "fr" and "fra" having nonunique completions.
	* symfile.c (sort_symtab_syms):  Ignore sort of zero symtab *.
	(symfile_init):  Print file format name when unable to handle it.
	(free_named_symtabs):  Use BLOCKVECTOR rather than obsolete BLOCKLIST.
	* symmisc.c (free_symtab):  Only free linetable if nonzero.
	* symtab.h:  Remove obsolete BLOCKLIST macros.

Thu Oct 31 18:12:43 1991  Stu Grossman  (grossman at cygnus.com)

	* infrun.c (wait_for_inferior):  another stepi/nexti fix.  Ensure
	that stop_step is 1 at bottom of main loop.  I don't know why this
	needs to be done, but it helps me sleep better at night.

Sun Oct 27 18:18:39 1991  Stu Grossman  (grossman at cygnus.com)

	* main.c (initialize_history):  Read history after reading all
	init files.

Sun Oct 27 14:09:25 1991  John Gilmore  (gnu at cygnus.com)

	* buildsym.c:  Break out initial malloc sizes.
	(record_line):  Record directly in a subfile.  Alloc on demand.
	(compare_line_numbers):  Add from xcoffread.c.
	(end_symtab):  New params say whether to sort pendings and
	linetable.  Patch block stabs if defined.  Shrink linetable before
	allocating the symtab.
	* buildsym.h:  Delete line_vector* and prev_line_number.  Add 
	global_stabs and file_stabs for xcoffread.
	* dbxread.c (start_subfile):  Move to buildsym.  Change above calls.
	* symtab.h:  LINETABLE(symtab) can now be null.  Zap LINELIST.
	* symmisc.c, symtab.c:  Cope with null LINETABLEs.

	* blockframe.c:  Pass fromleaf to INIT_EXTRA_FRAME_INFO.
	* tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
	tm-sparc.h:  Accept fromleaf parameter.
	* c-exp.y (yyerror):  Pass error message if given.
	* configure.in:  Add rs6000 host and target.
	* inflow.c (new_tty):  O_NOCTTY kludge for RS/6000.
	* symfile.h (entry_point):  Add.

Sat Oct 26 00:16:32 1991  John Gilmore  (gnu at cygus.com)

	* buildsym.c:  New file.  Breaks out symbol-table-building routines
	from dbxread.c, so they can be shared with xcoffread.c.
	* buildsym.h:  New file.  Declarations for buildsym.c users.
	* dbxread.c:  Remove large chunks into buildsym.c.
	* Makefile.in:  Add buildsym.c and buildsym.h.

	* symfile.c (syms_from_bfd):  New routine.
	(add_symbol_file):  Call it to do the real work.
	(syms_from_bfd):  Initialize entry_point before calling symfile_init.
	* symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
	Avoid declaring or setting entry_point (symfile.h & symfile.c cope).

Fri Oct 25 18:59:32 1991  Per Bothner  (bothner at cygnus.com)

	Various fixes to improve g++ debugging.
	* symtab.h:  Add is_const and is_volatile flags for each method.
	These are bit fields - take their space from voffset,
	which shrinks to 30 bits.  Since voffset is now a bitfield,
	make it unsigned for portability.  This changes its interpretation
	slightly:  Static methods now have voffset 1 instead of -1,
	and virtual offsets start at 2, not 1.
	* symtab.c:  Renamed gdb_mangle_typename to gdb_mangle_name,
	since it now returns an entire magled method name, not just
	the type part.  This avoids some duplication.
	It also allows us to correctly mangle const and volatile
	methods (using the new is_const and is_volatile bit fields
	mentioned above).
	* valprint.c (type_print_base), values.c (check_stub_method):
	Simplify by using new gdb_mangle_name.
	* values.c (value_headof):  Fix to correctly handle single
	inheritance (actually two fixes, either of which suffices).
	* dbxread.c (read_struct_type):  Handle const and volatile
	method specifiers.
	* dbxread.c (read_struct_type):  Yet one more place where
	we must handle '\\' continuations.
	* valprint.c (vtbl_ptr_name): Add final '\0'.

Fri Oct 25 16:06:38 1991  Stu Grossman  (grossman at cygnus.com)

	* tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE):  fix output of
	short return values for sparc and 68k.  Patch from Paul Eggert.

	* coffread.c, coredep.c, i386-xdep.c:  install patches for
	SysV/386 3.2 from Mauro DePalma.

Fri Oct 25 02:02:13 1991  John Gilmore  (gnu at cygnus.com)

	* core.c (core_file_info), exec.c (exec_file_info):  Print file
	type.  Use printf_filtered.

	* valops.c (value_fetch_lazy):  Avoid 0-length fetches.

Thu Oct 24 23:06:40 1991  Fred Fish  (fnf at cygnus.com)

	* dwarfread.c:  Add casts to remove compiler warnings.

	* tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
	tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
	tm-sun3.h:  Remove locally duplicated code for calling functions
	in the inferior.  The only differences were in the specific trap
	vectors used and whether or not an fpu was present.  These are
	now handled by appropriate definitions of BPT_VECTOR and
	HAVE_68881 respectively.  Other minor obvious cleanups.

	* valops.c:  Correct a minor misspelling.

	* utils.c:  Remove local BSD/USG hacks that are now in libiberty.

	* dwarfread.c:  Remove prototype for dwarfwarn.  Does not work
	with <varargs.h>.

Thu Oct 24 09:33:44 1991  John Gilmore  (gnu at cygnus.com)

	* stack.c (frame_command):  Always print.  Use new
	frame_select_command to select a frame without printing.	

	* dwarfread.c:  Use <varargs.h>, since <stdarg.h> is not portable.

Thu Oct 24 01:32:51 1991  Fred Fish  (fnf at cygnus.com)

        * dwarfread.c: New file for DWARF debugging format support.

	* elfread.c: New file for ELF object file format support.

	* procfs.c: New file for SVR4 /proc (process file system) support.

	* tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
	Amiga UNIX support.

	* xm-svr4.h, tm-svr4.h: New files for SVR4 support.

	* xm-m68k.h: New file for host machines with m68k cpu.

	* Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
	Add elfread.o and dwarfread.o to OBS.

	* symfile.h: Add "elf" to list of supported formats in comment.

	* c-exp.y, defs.h, symtab.h, valprint.c:  Add three new builtin
	types to gdb, builtin_type_long_double, builtin_type_complex, and
	builtin_type_double_complex.  Add and use new TARGET_SHORT_BIT,
	TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
	TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
	TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
	types on the target machine (ala the existing TARGET_LONG_LONG_BIT).

	* infrun.c:  When using SVR4 /proc interface instead of ptrace(),
	call proc_set_exec_trap() to setup child to stop at first instruction.

	* inftarg.c: When using SVR4 /proc interface, call proc_wait()
	rather than wait().

	* m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
	supply_fpregset(), and fill_fpregset(), which are machine
	dependent support routines for SVR4 /proc interface.

	* utils.c: Add warning_setup() and warning().  Warning() behaves
	the same as error() except that it returns normally rather than
	jumping back to command level.  Modules that don't want to call
	warning() for some reason, but want to produce their own warnings,
	can call warning_setup() to ensure compatibility with the way
	warning() and error() deal with the terminal.

	* symtab.c: Make internal errors produce more useful messages.

	* tm-68k.h: Move code that is duplicated in almost every single
	m68k based machine's configuration files to this common file.
	Duplications in the configuration files still need to be removed
	(FIXME).

	* infrun.c (child_create_inferior): System V versions must call
	setpgrp() with no arguments, to comply with prototyping typically
	in <unistd.h>.

	* munch: Add support for SVR4 style nm output.

	* dbxread.c, mipsread.c symmisc.c, symtab.c:  Remove the object
	file specific fields from the partial symbol table structure and
	replace them with a pointer to private data for each different
	flavor of object file reader to initialize appropriately.

Wed Oct 23 09:38:20 1991  John Gilmore  (gnu at cygnus.com)

	* xconfig/sun[34]os4:  Add note about strstr botch on sunos4.0.3c
	and previous.

	* mipsread.c (fixup_undef_type):  New function.  If a struct /
	union / enum is defined in a header file but nowhere else used,
	(by typedefing, pointer referencing or declaration) the mipsread code
	builds the complete tree for the structure but leaves its code as
	TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
	Guess its type based on the details of the members.

Tue Oct 22 18:04:32 1991  Stu Grossman  (grossman at cygnus.com)

	* infrun.c (wait_for_inferior):  Check return value from
	find_pc_line.

Mon Oct 21 17:47:03 1991  Stu Grossman  (grossman at cygnus.com)

	* infrun.c (wait_for_inferior):  fix stepi/nexti that was broken
	by my last edit to this routine.

Mon Oct 21 14:27:43 1991  John Gilmore  (gnu at cygnus.com)

	* tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
	FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
	the values before putting them into the dummy code.  (From Peter
	Schauer)

Mon Oct 21 10:04:39 1991  Steve Chamberlain  (steve at rtl.cygnus.com)

	* configure.in: added ebmon target.

Wed Oct 16 22:49:58 1991  John Gilmore  (gnu at cygnus.com)

	GDB-4.2 release!

	* Makefile.in:  Roll VERSION to 4.2.
	* README, TODO, WHATS.NEW:  Update.

	* core.c (core_open):  Improve error message for bad file.
	Pass .reg virtual memory address to fetch_core_registers to help
	it find the registers in the core-file header.
	* coredep.c (fetch_core_registers):  Take new argument, use it,
	and pass it to register_addr to locate the block of registers.
	* xm-mips.h:  Update KERNEL_U_ADDR for new scheme.  Cleanup a bit.

	* dbxread.c (read_dbx_symtab, process_one_symbol):  Handle
	Sequent N_FN_SEQ like everybody else's N_FN.

	* main.c:  Circumvent SCO cc bug with #if !!defined(USG).
	* tm-i386v.h:  #endif guck.
	* xconfig/i386*:  Remove -Dgetpagesize()=4096 kludge.
	* xconfig/i386sco:  Add HAVE_STRSTR to avoid ANSI bdeath.
	* xconfig/tahoe:  Add REGEX, which seems to be missing.

	* coredep.c:  Add <sys/types.h> for SCOnix.
	* dbxread.c (read_dbx_symntab):  Avoid coredump on malformed file.
	* printcmd.c (print_formatted):  Flush output before disassembly.

Tue Oct 15 20:12:32 1991  Roland H. Pesch  (pesch at fowanton.cygnus.com)

	* doc/refcard.tex (sec "Working Files"): consistent metavars and
	other improvements, due to comments by François Pinard
	(pinard@iro.umontreal.ca) 

	* doc/gdb.texinfo (appendix "Installing GDB"): changes in
	configure, and improvenets related to Pinard's refcard comments

Tue Oct 15 08:45:12 1991  John Gilmore  (gnu at cygnus.com)

	Changes from Fred Fish:
	* tm-68k.h (FPI_REGNUM):  Add.
	* infrun.c (child_create_inferior):  flush stdout and stderr
	before forking.
	* configure.in:  Handle amigados, amix hosts and targets.
	* inflow.c:  Handle TIOCGLTC_BROKEN for Amiga.

	From Andreas Schwab:
	* values.c (show_convenience):  Use printf_filtered.
	* main.c (define_command):  Check result of lookup_command for
	exact match.
	(echo_command):  Use printf_filtered, and force output out.

	* dbxread.c (read_enum_type):  Avoid Modula-2 kludge that breaks C
	programs.
	* i387-tdep.c (double_to_i387):  Fix typo for double_to_ieee_extended.
	* utils.c (_initialize_utils):  If !ISATTY, don't paginate.
	* configure.in, tconfig/decstation, xconfig/decstation:  Rename
	dec3100 to decstation.

Mon Oct 14 13:37:50 1991  Roland H. Pesch  (pesch at cygnus.com)

	* doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
	(nodes Continuing and Stepping; Memory; Targets) clarifications
	due to Larry Breed

Fri Oct 11 23:27:06 1991  John Gilmore  (gnu at cygnus.com)

	* tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h:  Move
	REGISTER_U_ADDR to corresponding xm- file.  Sugg. by Peter Schauer.

	* symmisc.c (print_partial_symtabs):  Add printpsyms debug cmd.

	* m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame):  Add
	generic routines for calling inferior functions.

	* blockframe.c (inside_main_scope, inside_entry_scope):  New.

	* copying.awk:  Filter formfeeds out of copying & warrantee.
	Make them available as `show copying' and `show warrantee' also.
	* main.c (print_gnu_advertisement):  Advt `show' commands.

Thu Oct 10 17:25:47 1991  John Gilmore  (gnu at cygnus.com)

	* mach386-xdep.c:  Even when cross-compiling, leave in the
	core-file reading code.
	* core.c (get_core_registers):  Avoid coredump if no .reg section.

Wed Oct  9 17:03:34 1991  John Gilmore  (gnu at cygnus.com)

	* mipsread.c, coffread.c:  initialise TYPE_VPTR_FIELDNO to -1.
	This avoids coredumps under `set print object on' in value_headof
	(called erroneously by value_from_vtable_info) for `p &struct'
	or `p *struct'.  From Peter Schauer.

Mon Oct  7 00:06:52 1991  John Gilmore  (gnu at cygnus.com)

	* Makefile.in:  Roll version to 4.1.2.
	* dbxread.c:  Use aout64.h, not a.out.gnu.h.  Get external symbol entry
	size from BFD (but, FIXME, we don't yet read external nlists's and
	convert them to internal nlists's before handling them -- we still
	assume they have the same size and alignment.)  Use SET_NAMESTRING
	everywhere useful.
	* exec.c (exec_file_command):  Move dead coff-encapsulation code
	to BFD.
	* m88k-tdep.c, m88k-xdep.c:  Remove encap test and #inc <a.out.h>.

Fri Oct  4 22:30:06 1991  John Gilmore  (gnu at cygnus.com)

	* configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
	* xm-i386mach.h, mach386-xdep.c, xconfig/i386mach:  New files.

Fri Oct  4 17:04:31 1991  Per Bothner  (bothner at cygnus.com)

	More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
	* mips-xdep.c (store_inferior_registers):  Don't try to
	write the (pseudo) FP.
	* mipsread.c (parse_partial_symbols):  Improved algorithm for
	setting pst->texthigh.

Fri Oct  4 16:47:32 1991  Roland H. Pesch  (pesch at cygnus.com)

	* doc/Makefile: make TEXINPUTS include . everywhere

Fri Oct  4 00:35:56 1991  John Gilmore  (gnu at cygnus.com)

	* coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h:  Remove
	vestiges of typevectors, which were for symsegs and are no longer
	used.  (From a question by Eliot Dresselhaus
	<dresselh@RFT30.nas.nasa.gov>).

Thu Oct  3 09:33:26 1991  John Gilmore  (gnu at cygnus.com)

    	* dbxread.c, coffread.c:  static-ize functions that were
	gratuitiously external.  (From Fred Fish.)

	* c-exp.y:  sym->class to SYMBOL_CLASS (sym).

	* dbxread.c (dbx_lookup_type):  Keep doubling size of typevector
	until it is large enough.    

	* dbxread.c (read_type):  Handle error case slightly better.
	Make complaint message not C++-specific.

Wed Oct  2 17:21:07 1991  Stu Grossman  (grossman at cygnus.com)

	* infrun.c (wait_for_inferior):  Fix step/next so that you only
	stop at the beginning of a new line.  This fixes various problems
	with for loops, nested if-else's and switch statements.

Tue Oct  1 06:33:55 1991  John Gilmore  (gnu at cygnus.com)

	* symtab.c (lookup_symtab_1, lookup_symbol):  "fatal" errors
	between symtabs and psymtabs become ordinary error()s.

	* dbxread.c (read_dbx_symtab):  Relocate end_of_text_addr
	properly, making "end pc" correct in shared lib psymtabs.
	(From Guy Harris <guy@auspex.com>.)

Mon Sep 30 13:15:31 1991  John Gilmore  (gnu at cygnus.com)

	* dbxread.c:  Enable, but soften, const_vol_complaint.
	(read_dbx_symtab):  N_STSYM and N_LCSYM define static vars.
	Ditto Gould N_NBSTS and N_NBLCS.  Also, all types in the psymtab
	should be file-scope, not global.
	(read_struct_type):  Remove ancient multiple-inheritance warning.
	(read_range_type):  Check base type, complain & patch if undefined.
	* stack.c (frame_info):  Demangle the function name in `info stack'.
	(From Peter Schauer)

Sat Sep 28 10:02:33 1991  John Gilmore  (gnu at cygnus.com)

	* eval.c (evaluate_subexp_for_address):  Don't use
	TYPE_POINTER_TYPE directly (it might be zero if this type has
	never had a pointer created before); use lookup_pointer_type.
	* symtab.c (lookup_method_type):  Arguments were swapped in all
	callers, so fix it here.  I'm amazed this worked at all!

Fri Sep 27 18:09:31 1991  John Gilmore  (gnu at cygnus.com)

	* c-exp.y, m2-exp.y:  Define more yysymbols that happen to be
	"bss" rather than "data" symbols, but which still conflict.
	* m2-exp.y:  Lint.

	* coffread.c (coff_symfile_read):  Use xmalloc, not malloc.
	* core.c (core_files_info):  Shorten output.
	* exec.c (exec_files_info):  Ditto.
	(build_section_table):  Ignore zero-length sections.

	* language.h (get_frame_language):  Declare.
	* saber.suppress:  update.
	* stack.c (find_relative_frame):  Remove complex code that was
	#if 0'd, stick with simple code.  Lint.
        * saber.suppress:  Update a bit.
	* symfile.c (add_symbol_file_command):  Add "?" to question.
	* utils.c (parse_escape):  Avoid \a due to bdead compilers.
	* value.h:  Declare typedef_print.

	* valprint.c (val_print, type_print_base):  TYPE_CODE_RANGE less
	kludgey.

	* nindy-tdep.c (nindy_frame_chain_valid):  Use lookup_misc_func.
	(Reported by Mark Peek <mark@imagen.com>.)

	* solib.c (solib_map_sections):  Relocate all sections, even
	though only the text section's size is tracked.  Mark ld_text
	for eventual elimination as we generalize to N sections.

	* infrun.c (wait_for_inferior):  Don't check if the PC is in a
	call_dummy if we were stopped by a random signal that is being
	passed to the program.  This produced wierd results when calling
	functions in the inferior and signals (e.g. SIGALRM) were in use.

Tue Sep 24 18:05:30 1991  John Gilmore  (gnu at cygnus.com)

	* infrun.c (IN_SIGTRAMP):  Not parenthesized properly.

	easier into README.
	* configure.in:  Rename rtpc CPU to romp to match config.sub.
	* README, WHATS.NEW, TODO:  Update for gdb-4.1.

Fri Sep 20 17:39:14 1991  Roland H. Pesch  (pesch at cygnus.com)

	* doc/gdb.texinfo: Updates from ChangeLog.  set/show write, 
	autoloading shared libs, copyright etc on GDB startup, clean up $_

	* doc/gdb.texinfo: merge new language-switching and lang-specific
	doc by Andrew Beers

Fri Sep 20 15:00:57 1991  Per Bothner  (bothner at cygnus.com)

	* mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
	compilers (which may lack stddef.h).

Fri Sep 20 13:29:42 1991  John Gilmore  (gnu at cygnus.com)

	* dbxread.c (read_dbx_symtab, process_one_symbol):  N_FN and
	N_WARNING are the same except for the N_EXT bit, so just use their
	values alone, rather than OR-ing them with N_EXT.

Fri Sep 20 12:27:55 1991  Stu Grossman  (grossman at cygnus.com)

	* mipsread.c (parse_lines):  Deal with negative extended line
	offsets correctly.

	* c-exp.y, m2-exp.y:  #define yyerrflag and yynerrs to avoid
	global symbol conflicts.

Fri Sep 20 02:28:15 1991  John Gilmore  (gnu at cygnus.com)

	* .gdbinit:  Move 'set complaints' to top, so it runs even in
	case we aren't debugging GDB.
	* language.c (_initialize_language):  Fix type check and range
	check documentation strings.
	* utils.c (!HAVE_VPRINTF):  Define vfprintf as a function, so
	language.c can use it.  (Though language.c should really not be
	handling warnings/errors the way it does, FIXME.)
	* symtab.c (lookup_primitive_type):  const lint.

	Bugfix from Peter Schauer:
	* source.c (lines_to_list):  Make signed, to avoid comparison
	going unsigned and complaining that -3 is too high for 21 lines.
	* stack.c (lines_to_list):  Ditto.

Thu Sep 19 23:33:41 1991  John Gilmore  (gnu at cygnus.com)

	* Makefile.in (HFILES):  Add minimon.h.
	(VERSION):  Roll version number to 4.0.95.
	(gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
	New rules for building distributions.  Normal distribution
	is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
	one level up from here; it calls make-proto-gdb.dir to build a
	directory `proto-gdb' which is an image of the release.  The old
	`gdb.tar.Z' rule still works too.
	* config.sub, configure:  Roll in latest from ..

Thu Sep 19 17:41:24 1991  Roland H. Pesch  (pesch at cygnus.com)

	* doc/gdbint.texinfo: Reorder contents; reorganize new-host,

	Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
	* mipsread.c (parse_partial_symbols): Enter the name of all
	structs/unions... into the psymtab so we can access them if the
	symtab is not read in.
	* mips-tdep.c:  Remove some unneeded #includes.
	* xconfig/dec3100: Add HAVE_STRSTR.

Thu Sep 19 15:14:23 1991  John Gilmore  (gnu at cygnus.com)

	* Makefile.in:  Circumvent Sun Make bug on *-exp.tab.o.
	* c-exp.y, m2-exp.y:  Lint.
	* m2-exp.y:  Avoid using yytname[] which is a Bison-ism.
	* valprint.c (val_print_fields):  Check for stub type.
	* mipsread.c (_initialize_mipsread):  Avoid using
	builtin_type_void at initialize time.
	(mipscoff_symfile_read):  use it now.	

Wed Sep 18 15:55:51 1991  John Gilmore  (gnu at cygnus.com)

Tue Sep 17 08:37:41 1991  John Gilmore  (gnu at cygint.cygnus.com)

	Add Andrew Beers' changes for Modula-2 support.  His ChangeLog
	entries are enclosed herein.  Not all of these changes
	have been merged into the master GDB sources -- check the
	ChangeLog above here for the merge log.

Mon Jun  3 17:05:45 EDT 1991

     m2-exp.y       Created.  Tested outside of GDB for a few days.  Proper
                    operators were added, C specific operators and tokens
                    removed.  yylex() revamped to some extent.  Still things
                    missing from the grammar, such as sets.
                    Tested for two weeks in GDB v3.5.

Tue Jun 11 17:23:48 EDT 1991

     m2-exp.y       Added boolean constants TRUE and FALSE to the grammar
                    so they are built-in.  Sort of a hack.

Fri Jun 14 12:53:51 EDT 1991

     m2-exp.y       Added range checking for numeric constants.  Any numeric
                    constant is assumed to be of builtin type INTEGER unless:
                    (1) it is octal or hexadecimal, in which case it is a
                    CARDINAL; (2) it is too big to fit into an INTEGER, in
                    which case it is a CARDINAL.
     eval.c         Added simple range checking for +, -, and * on integers.
                    Doesn't work very well for *, since 6 * 1,000,000,000 =
                    1,705,032,704, which fails the simple test of result >=
                    first_operand, no matter in what order the operands are.

Tue Jun 18 14:11:30 EDT 1991

     Broke the parser into parts, one containing the C grammar and the other
     containing code to be shared by all of the grammars.

     The following files no longer exist:

          expread.y
          expread.tab.c

     The following files were added:

          c-exp.y        (The C grammar)
          m2-exp.y       (The Modula-2 grammar)
          parser-code.c  (Code that is shared by the above grammar)
          parser-code.h
          parser-defs.h

     Makefile.dist  Changed to reflect the above dependencies.  NOTE:  It is
                    now necessary to use the Bison compiler compiler, since it
                    will generate function/variable prefixes other than yy.

Tue Jun 18 16:47:49 EDT 1991

     symtab.[ch]    Added the external variable working_lang, than holds the
                    value of the current working language.
                    Added the ennumerated type language_mode, with the values
                    language_auto and language_manual, the former meaning that
                    GDB sets working_lang as needed, and the latter meaning
                    that the value of working_lang is totally under user
                    control.
     symtab.[ch]    Added the Modula-2 pervasive types INTEGER, CARDINAL,
                    REAL, BOOLEAN and CHAR.  Also added the type codes
                    TYPE_CODE_BOOL and TYPE_CODE_CHAR.
     utils.c        Added set_language_command and show_language_command to
                    implement the GDB support commands "set language" and
                    "show language".
     expression.h   A number of identifiers were added to the type exp_opcode
                    to facilitate Modula-2 builtin functions, integer
                    division, and array indexing.

Wed Jun 19 13:25:58 EDT 1991

     language.h     Added the macro STRICT_TYPE, which evaluates to non-zero
                    if the language specified by working_lang requires the use
                    of strict typing of expressions.  Eventually, even this
                    will be able to be changed by the user.
                    Added the macro RANGE_CHECK, which evaluates to non-zero
                    if the language specified by working_lang requires the
                    checking of a value against the domain of its type.
                    Eventually, even this will be able to be changed by the
                    user.
     language.[ch]  Predicates involving types (simple_type, ordered_type,
                    same_type, integral_type, numeric_type, character_type,
                    boolean_type, float_type) are added.  These predicates are
                    based on the current value of working_lang, and are handy
                    in type-checking.

Wed Jun 19 15:39:34 EDT 1991

     eval.c         Added the function type_array_rank which computes the rank
                    of an array type.
     valarith.c     Added the funtion value_bool, which when given a integer
     value.h        value (ie. struct value *) as an argument, it returns a
                    boolean value (ie.  struct value *) true if that integer
                    is non-zero, and a boolean value false otherwise.
     valprint.c     Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
                    will print out properly.

Wed Jun 19 16:36:34 EDT 1991

     valops.c       Added the function value_capitalize, which returns it
     value.h        argument capitalized if its argument is a lowercase
                    letter, or the argument unchanged if its argument is not a
                    letter.
     valarith.c     Added the function range_check_p, which returns non-zero
     value.h        if its value argument is between the integral bounds upper
                    and lower.
                    Added the function range_check_enum_p, which makes sure
                    that its value argument is a valid member of the domain of
                    its type argument.
                    Added the function range_check_range_p, which makes sure
                    its value argument lies between the upper and lower bounds
                    of its type argument, which must be a ranged type.
                    Added the function check_array_index, which range and type
                    checks an index of an array.
                    Added the function value_multi_subscript, which computes
                    array[idx1,idx2...idxN], given a value array and an array
                    of values representing indicies.
     values.c       Changed value_from_long to work with TYPE_CODE_CHAR and
                    unpack_long to work with TYPE_CODE_BOOL and
                    TYPE_CODE_CHAR.

Wed Jun 19 18:04:08 EDT 1991

     symtab.c       Stored pervasive types in a structure and make
                    lookup_pervasive_type() a lookup function that was based
                    on working_lang.  If lookup_pervasive_type() returned
                    non-zero, then that value was returned (a fix, since
                    before it simply wouldn't return the pervasive type.)
     language.h     Added the macro CAST_IS_CONVERSION, which evaluates to
                    non-zero if the language specified by working_lang means
                    "conversion" when it says "cast".
     valops.c       Added the function value_real_cast(), which performs a
     value.h        *cast*, not a *conversion*, which is what value_cast()
                    does when it can.  In particular,
                    value_cast(<float_type>,4) = 4.0, while
                    value_real_cast(<float_type>,4) = some mess.
     eval.c         Modula-2 builtin functions implemented:  ABS, CAP, CHR,
     parser-code.c  FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.  
     expression.h   Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
                    and MIN on integral types.  *NOTE*: These are currently
                    hardcoded to work only if there are 8 bits per storage
                    unit.  FIXME.
     eval.c         Made logical functions call value_bool to return a
                    properly typed boolean value, based on working_lang.

Thu Jun 20 11:55:27 EDT 1991

     valprint.c     Types now print out in a Modula-2 fashion.  This works for
                    the cases when the type is printed out step-by-step, that
                    is, it doesn't work when the name of a structured type
                    (which includes the keyword "struct", etc.)  is simply
                    displayed.
                    FIXME:  Perhaps this is bad.  Parts of it seem to kludgey,
                    since type specifications in C and Modula-2 are very
                    different.  The C printing of a type is very recursive,
                    whereas in Modula-2 it is generally very simple.  C has
                    type prefixes and suffixes, which have no real analogue in
                    Modula-2.  Maybe type_print() should call a language
                    specific type printer.  This is also advantageous if we
                    compile GDB to exclude some of the languages.  We'll just
                    leave those functions out.

Thu Jun 20 16:57:10 EDT 1991

     dbxread.c      When reading the complete symbol table in (via
                    psymtab_to_symtab()), the number and types of function
                    arguments are added to a function type.  define_symbol()
                    calls add_param_to_type() to accomplish this.
                    Assumption:  when we come across a function definition
                    (N_FUN symbol with an 'f' or 'F' in the name), its
                    arguments will appear before another function definition.
                    When a function is found, a pointer to its type is placed
                    in the global in_function_type.  Changes that
                    add_param_to_type() makes are to this global.
     valprint.c     The type of a function now includes (for Modula-2) the
                    types of its parameters.
     eval.c         Type checking and a check for the proper number of
                    arguments is now done for function calls.  Not sure of the
                    impact this has on C++ member function yet.

Thu Jun 20 19:58:48 EDT 1991

     valprint.c     Rewrote the type printer.  Broke it into two language
                    specific parts, adding the functions type_print_m2() and
                    type_print_m2_1().
                    An unfortunate consequence is this:  if you debugging a C
                    program in Modula-2 mode (why?), info types does not work
                    well with regular expressions, since the types are printed
                    out in Modula-2 terminology, but stored in C terminology.
     language.[ch]  Added the functions new_type_last(), type_keyword(), and
                    type_sep() to aid in the printing of typedefs.
     symtab.c       Made the printing of typedefs as language independent as
                    possible through calls to new_type_last(), type_keyword(),
                    and type_sep().

Fri Jun 21 11:50:26 EDT 1991

     dbxread.c      Check all incoming ennumerated types.  If it looks like
                    Modula-2's BOOLEAN type, then change the type_code of the
                    type to TYPE_CODE_BOOL so we can process it as a boolean
                    variable.
     valprint.c     Replaced some of the 0x%x with calls to sprintf and
                    hexformat() in val_print().
     language.[ch]  Added the function hex_to_string(), which converts its
                    integral argument to a hexadecimal number (format is
                    language based) and returns the result as a string.

Mon Jun 24 12:25:07 EDT 1991

     valprint.c     Some functions call type_print_1() directly, instead of
     value.h        using type_print(), so they can specify where (column) to
                    print things.  Since type_print() takes care of language
                    dependence, that needs to be called first.  Added a
                    parameter depth to type_print() (so it is now like
                    type_print_1).  Changed type_print to type_print_at, and
                    made type_print a macro that passes a depth argument of
                    zero.
     symmisc.c      Changed all calls to type_print_1 to calls to
                    type_print_at.
     Makefile.dist  Made it possible to build GDB for a specific set of
     depend         languages.  Do this by passing a definition for the macro
                    LANGS to make.  LANGS should be a string containing a
                    space-separated list of language names (ie. LANGS="c m2").
                    The default is to build all languages.  Note that grammar
                    files must follow the naming convention of <lang>-exp.y.
     gdb.lang       This holds the current value of the LANGS macro.  It is
                    examined every time make is called, and is updated if
                    necessary.
     eval.c         Added #ifdef _LANG_<lang> to these files.
     expread.c      Still need to add them to dbxread.c and coffread.c.
     main.c
     source.c
     symtab.c
     utils.c
     valarith.c
     valprint.c

Mon Jun 24 16:33:11 EDT 1991

     language.[ch]  Added the functions hexformat_pre() and
                    hex_to_string_pre(), which take a prefix argument to
                    include in the format string.  Thus, hexformat_pre("08") will
                    return "0x08x" (if the working language is language_c). 
                    Made hexformat() and hex_to_string() calls to the above
                    with "" as the prefix argument.

     am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
     dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
     infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
     mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
     pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
     stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
     valprint.c, vax-pinsn.c

          Changed all occurences of 0x%[0-9]*l*x in printf format strings to
          calls to hexformat() and hex_to_string().  Format strings without
          the leading "0x" were ignored.

     depend         Updated to take the above into account.


Tue Jun 25 15:27:18 EDT 1991

     symtab.h       Added the types range_mode_t, range_check_t, type_mode_t,
                    and type_check_t to keep track of the current state of
                    range and type checking.
     main.c         Added the variables range_mode, range_check, type_mode,
                    and type_check to record the current state of range and
                    type checking.  Added initialization code to main().
     language.h     Changed the macros STRICT_TYPE and RANGE_CHECK to examine
                    the above variables.


Tue Jun 25 17:57:08 EDT 1991

     dbxread.c      process_one_symbol() updates the variable (enum language)
                    source_lang based on the extension of the filename
                    contained in the N_SO sybmol that started this symtab.
                    When end_symtab() is called, the value of source_lang is
                    put into the language field.
     stack.c        select_frame() sets working_lang (and possibly type_check
                    and range_check) to the language field of the symtab
                    associated with the frame that is selected if working_mode
                    is language_auto.  If working_mode is language_manual, a
                    warning is printed and working_lang is not set.
     language.c     Added the function set_type_range(), which sets the value of
                    type_check and range_check (if their modes call for
                    automatic setting) based on the current value of
                    working_lang.  A non-zero argument will cause the current
                    settings to be output.


Wed Jun 26 14:51:40 EDT 1991

     eval.c         Added range checks on assignment.
     m2-exp.y       Added the grammar for sets to the language.  Currently,
                    these do not do anything except print an error message.

Wed Jun 26 17:01:04 EDT 1991

     m2-exp.y       Added the ability for parse_number() to parse negative
                    numbers.  A global flag is set upon encountering a unary
                    minus.  This was done to make, for example, 1 parse as a
                    CARDINAL, and not as an integer, per Wirth's examples in
                    Programming in Modula-2 ed.4.
     valprint.c     Added support for "set radix 2" by then setting
                    output_format to 't'.
     eval.c         Implemented range checking on subrange types.  Added calls
                    to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
                    Implemented MIN and MAX for ennumerated types.  The
                    minimum value of an ennumerated type is defined by Wirth
                    as the first identifier, and the maximum as the last.
     m2-exp.y       Made octal numbers ending with "B" be characters and those
                    ending with "C" be numbers, per Wirth's book. (p. 34)
          
Thu Jun 27 14:11:52 EDT 1991

     stack.c        select_frame() now only sets working_lang, it does not
                    notify the user.  If working_mode is language_manual, then
                    a warning is issued once.
     main.c         At the end of each call to execute_command(), working_lang
                    is checked against the local static (enum language)
                    current.  If they differ and working_mode is
                    language_auto, the new settings of language, type and
                    range checking are printed out.
     stack.c        Modified frame_info() to include the language of the
                    current frame in the output of "info frame".
     language.[ch]  Added the function language_str() which returns the name
                    of the current language.

Fri Jun 28 15:33:14 EDT 1991

     m2-exp.y       Added the built-in procedures INC, INCL, DEC, and DECL to
                    the language.  INCL and DECL currently cause an error,
                    since sets are not implemented yet.  INC and DEC are
                    implemented as PREINCREMENT/PREDECREMENT with one
                    argument, and as ASSIGN_MODIFY with two arguments.
     eval.c         Added type checking to the above cases.
     value.h        Added not_lval_constant to the lval_type ennumerated type.
                    not_lval_constant means that the value is a constant
                    value; that is 3 or 'a' or TRUE, not as in a constant
                    identifier.  This is used to help coerce numbers such as 3
                    to either signed or unsigned numbers.
     valops.c       Added the function value_coerce_constants() which coerces
                    constant integers as following:  if one is a constant and
                    the other is not, the constant's type is set to the type
                    of the other argument.  If both are constants and one is
                    signed, the other is converted to a signed constant.

Sat Jun 29 17:26:29 EDT 1991

     valarith.c     Added a better range checker.  It now checks range
                    (successfully) on integral operations [+-] (signed and
                    unsigned) for any C sized type.  Still does not work well
                    for multiplication.)
                    int_in_size() returns an integer that is coerced to fit into
                    specified number of bytes.

Mon Jul  1 13:04:14 EDT 1991

     language.[ch]  Added the function binop_result_type(), which returns the
                    builtin (struct type *) type that would be the result of a
                    binop on the two values V1 and V2.

Wed Jul  3 19:22:53 EDT 1991

     source.c       Extended source_info() to include the source language in
                    the output from "info source".
     
Fri Jul  5 13:48:52 EDT 1991

     utils.c        Moved the support functions for the GDB set/show commands
                    dealing with language into language.c.
     language.c     Added the function language_info(), which displays info
                    about the current working language, type and range check
                    settings.  Called via the GDB command "info language".
                    Added an initialization routine _initialize_language(),
                    that sets defaults for the language, type and range
                    variables and sets up the new GDB commands.
     main.c         Language setup moved to language.c.
     depend         Rebuilt.

Mon Jul  8 10:10:22 EDT 1991

     valarith.c     Debugged the range checker for arithmetic.  Still does not
                    work for multiplication very well.

Mon Jul  8 12:40:37 EDT 1991

     language.[ch]  Added the function value_true() which returns non-zero if
                    its argument represents a boolean true value.
     breakpoint.c   Changed breakpoint_cond_eval() to call value_true() to
                    check the truth of an expression.

Thu Jul 11 12:51:34 EDT 1991

     language.[ch]  Added the predicate structured_type(), which returns
                    non-zero if the argument is a structured type.
                    Added the predicate pointer_type(), which returns non-zero
                    if the argument is a pointer type.
     eval.c         Added the ability to do addition and substraction on
                    pointers and integers.   This case simply bypasses the
                    type checker.

Thu Jul 11 14:41:42 EDT 1991

     include/stab.def
                    Added the symbol N_DEFD (0x4a) which is a definition
                    module dependency that is used by the GNU Modula-2
                    compiler and the linker.  It is not important to GDB,
                    except that [dbx|coff|mips]read.c should ignore these
                    symbols.

Fri Jul 12 16:07:00 EDT 1991

     valprint.c     Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
                    0 in val_print().  Also added statements to the else part
                    to coerce type (argument to val_print) to a pointer type
                    if it is an "array of unspecified length".
     valops.c       Added the function value_m2_string(), which returns a
                    (value) value which is a constant string, whose type is
                    (ARRAY [0..n] OF CHAR).  The length field of the type
                    structure is set to zero, so it will be interpreted as an
                    "array of unspecified length".
     stack.c        Moved the language/frame mismatch check to
                    main.c:execute_command().
     main.c         The working language is recorded each time
                    execute_command() is executed.  If working lang has
                    changed during its execution, then the new
                    language/type/range info is printed out for the user.  If
                    the working language does not match the language of the
                    frame, a warning is issued.

Sat Jul 13 16:16:39 EDT 1991

     eval.c         Moved all the type-checking stuff for operators to
     language.[ch]  language.c.  This is so we can keep language-specific
                    stuff (like for what type operators are defined) in
                    language.c.
     language.[ch]  Added the function binop_type_check(), which checks to see
                    if its two (value) arguments are type-compatible with its
                    opcode argument.  The opcode should represent an operation
                    involving an operator.  Also added the macro function
                    unop_type_check, which calls binop_type_check with a
                    NULL second argument.
     expprint.c     Added Modula-2 operators to the op_print_tab, so info
     expression.h   break works correctly.  Also added "op_string", which
                    returns the string corresponding to the (enum exp_opcode)
                    opcode that is its argument.


Sat Jul 13 18:26:18 EDT 1991

     coffread.c     Added code to record the type of function arguments with
                    each paricular function.  Code is very similar to that
                    added to dbxread.c.  
     dbxread.c      Moved add_param_to_type() to symtab.c
     symtab.[ch]    Added function add_param_to_type() from dbxread.c

     *** NOTE:  The above additions have not been tested.

Mon Jul 15 12:50:47 EDT 1991

     langauge.[ch]  Added the functions type_error and range_error, which work
                    like error() except if the type/range mode is set to
                    *_mode_warn, then they do not do a return_to_top_level(),
                    but merely print a warning.
                    Also changed [set|show]_[type|range]_command() to support
                    the new "warn" feature.

Thu Jul 18 17:50:54 EDT 1991

     mipsread.c     Added code to record the type of function arguments with
                    each particular function.  Code is very similar to that
                    added to dbxread.c.  

     *** NOTE:  The above additions have not been tested.

Fri Jul 19 11:19:10 EDT 1991

     defs.h         Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
                    UMIN_OF_SIZE, which when given a size of a numeric type,
                    return the maximum and minimum value it can hold.  UMAX...
                    and UMIN... return the result for unsigned types.
     symtab.h       Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
                    struct types.  They call above macros.
     dbxread.c      Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
                    avoid a name conlict with the above.
     c-exp.y        Added range checking on numeric constants in
                    parse_number() for completeness.
     valarith.c     Made binop_user_defined_p() and unop_user_defined_p()
                    return 0 if working_lang is not language_c.

	breakpoint.c	Documentation strings of some commands changed to
				eliminate the references to the C language where
				appropriate.

Tue Aug 13 15:48:03 EDT 1991

	m2-exp.y		Added qualified identifiers to the grammar.  The semantics
				are slightly different from those of the GDB operator ::
	c-exp.y
	m2-exp.y		Added a rule to each grammar of the form:  start ::= exp |
				type_exp, where type_exp is any valid type expression.
	expression.h	
	eval.c		Added the opcode OP_TYPE, and an error case in eval.c.
	printcmd.c	Modified ptype_command() so it actually parses the input
				(necessary for type expressions with scope qualifiers).
				Added the function ptype_eval() which expects an
				expression composed of one OP_TYPE element.
	*.[ch]		Replaced all occurences of parse_c_expression with
				parse_expression
	*.[ch]		Replaced all occurences of parse_c_1 with parse_exp_1

[End of ChangeLog entries from Andrew Beers for Modula-2 support.]

Mon Sep 16 17:19:46 1991  John Gilmore  (gnu at cygnus.com)

	Small fixes from Peter Schauer:

	* infrun.c (child_attach):  Lint.
	* solib.c (find_solib):  Handle shared libs version 2.

	Small fixes from David Wood:

	* xm-ultra3.h (SYS_SIGLIST_MISSING):  Typo.

	Small fixes:

	* remote-vx.c:  Move <stdio.h> to top, for FILE.  Fix from
	John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.

	* utils.c (wrap_here):  Avoid wrap action of fputs_filtered if
	chars_per_line is at maximum (user typed `set width 0').  Fix
	from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.

Tue Sep 17 17:31:04 1991  Stu Grossman  (grossman at cygnus.com)

	* coredep.c:  include ptrace.h where necessary.
	* mipsread.c(parse_lines):  fix unsigned char problem that was
	messing up line numbers on SGI's and possibly other MIPS based
	platforms.
	* infrun.c (child_create_inferior):  use better test to check
	return val from setpgrp().
	* tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3:  add these
	for sgi/irix support.

Wed Sep 18 04:33:31 1991  Per Bothner  (bothner at cygnus.com)

	* mipsread.c (parse_symbol):  Put non-static procedures
	in the global block.

Fri Sep 13 00:14:52 1991  John Gilmore  (gnu at cygnus.com)

	Patch together `text_start' and `text_end' for 29K port.

	* exec.c (exec_command):  If NEED_TEXT_START_END, define the
	variables and set them based on the exec file.
	* am29k-tdep.c:  declare text_start.
	* valops.c (call_function_by_hand):  declare text_end.

	* inferior.h:  Eliminate CANNOT_EXECUTE_STACK in favor of
	defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END.  This is
	because machines that do this will also have to know to
	set NEED_TEXT_START_END.  Besides, it was a redundant way to
	say the same thing.
	* tm-29k.h, tm-convex.h, tm-np1.h:  Eliminate
	CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
	NEED_TEXT_START_END.

Thu Sep 12 00:22:24 1991  John Gilmore  (gnu at cygint.cygnus.com)

	AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:

	* Makefile.in (CLIBS):  Put XM_CLIBS and TM_CLIBS at end.
	Pass MUNCH_DEFINE to munch whenever we run it.
	* am29k-pinsn.c (print_insn):  Handle NOP specially.  Avoid %#x
	format string; use 0x%x instead.
	* am29k-tdep.c:  Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
	* ultra-xdep.c, xm-ultra.h:  New files for Ultracomputer host system.
	* xm-rtbsd.h:  New host support for RT/PC running BSD Unix.
	* inflow.c:  Handle `short' process group IDs.
	* infptrace.c (fetch_register):  Support CANNOT_FETCH_REGISTER,
	and check for ptrace errors.
	* coffread.c (SDB_REG_TO_REGNUM):  Define if not already.
	(coff_symfile_init):  Initialize text_bfd_scnum.
	(read_coff_symtab):  Use it to find the text [and absolute?] sections.
	* ../config.sub:  Add vendor nyu and os "sym[1-9]*".
	* configure.in: Add hosts rtpc-*-* and a29k-*-*.
	Merge target arm case with other "easy" cases.  Add target
	cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
	Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
	process).
	* minimon.h, remote-adapt.c, remote-mm.c:  Add.
	* munch:  Cope with RT/PC putting fns in data segment.
	Restore ability to override `nm' by specifying MUNCH_NM.
	* xconfig/rtbsd, xconfig/ultra3:  New host systems.
	* tconfig/a29k:  Rename from tconfig/am29k.  Add remote-mm
	and remote-adapt.  Remove encapsulated coff #define's (the
	support should go in BFD, and gdb shouldn't know or care).
	* tconfig/a29k-kern:  Same, but for remote kernel debugging.
	* tconfig/ultra3:  For debugging user processes on Ultra3/Sym1.
	* tm-29k.h:  Update BADMAG (though it should go away).
	Allow the register definitions to be overridden in another
	tm-file.  Fix SR_REGNUM.  Add a mess of _REGNUM's.  Separate
	RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
	DUMMY_SAVE_GR96, for handling kernel calling conventions
	that use GR64+ rather than GR96+.
	* tm-ultra3.h:  New file, for use on Ultra3 Unix as well as for
	remote debugging of Ultra3 kernel.  Includes tm-29k.h and
	overrides various things.

	* remote-mm.c (mm_attach, mm_wait):  Handle attach like
	child_attach does, making a clean stop in the newly attached
	program.
	* remote-eb.c:  Lint.

	* coffread.c:  Make coffread independent of any particular
	variant of COFF.  Avoid #include-ing any particular one except
	internalcoff.h.  BFD now passes key values for symbol reading
	as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
	and the symbol masks and shifts); use them.
	Remove obsolete end_of_text_addr.

	* exec.c:  Remove unused include files.

Wed Sep 11 19:38:44 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* Makefile.in (documentation targets):  Pass $(M4).
	Bugfix from eggert@twinsun.com (Paul Eggert).

	* stack.c (down_silently_command):  Check for stack existence.

Tue Sep 10 23:08:29 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* Makefile.in (VERSION):  Update to 4.0.3.

Tue Sep 10 09:19:29 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* core.c (core_file_command):  Print frame at coredump with
	its level number, by calling print_stack_frame.
	* frame.h:  Add selected_frame_level, print_stack_frame.
	* frame.h, stack.c:  Remove print_sel_frame, print_selected_frame.
	* convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
	Change print_sel_frame and print_selected_frame callers to
	print_stack_frame.

	* dbxread.c (read_ofile_symtab):  Avoid empty else clause.
	* symfile.c (free_named_symtabs):  Ditto.
	* main.c (main):  wrap_here needs an arg.

	(solib_add):  Avoid noise.  
	(solib_create_inferior_hook):  Lint.
	(sharedlibrary_command):  Move dont_repeat to here.
	* utils.c (error):  Call wrap_here to force buffered output.

	Small patches from Peter Schauer:

	* coffread.c (start_symtab):  Free any existing line_vector before
	malloc-ing new one.
	(read_coff_symtab):  Ditto for type_vector.

	* source.c (lines_to_list):  New variable, replacing function.
	(all uses):  Use as variable.
	(_initialize_source):  Add 'set listsize' and 'show listsize'.
	* utils.c (lines_to_list):  Remove function.
	* stack.c (print_frame_info):  Use as variable.
	* defs.h (lines_to_list):  Remove declaration.

Mon Sep  9 13:45:57 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* breakpoint.c (insert_breakpoints):  Restore warning about
	the program might be running in another process, but only for
	systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
	* xm-hp300bsd.h, xm-mips.h, xm-vax.h:  Define it.

	* utils.c (error):  if error_pre_print is set, print the string
	first.
	* main.c (main, print_gnu_advertisement, print_gdb_version):
	Reformat legalese so it always prints, but acts as an "I'm here"
	message while symbols are being read.  If any errors occur,
	print a few newlines to set off the message and start it at the
	left margin.  Remove mention of "help" command, and don't yak
	about symbol reading.
	(catch_errors):  Error string is now printed first in case of
	error, not last.
	* command.c (undef_cmd_error, lookup_cmd):  On undefined command,
	suggest the "help" command.

	* Makefile.in (VERSION):  Set to 4.0.2.

Thu Sep  5 23:49:48 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* .gdbinit:  Remove useless "rr" command.  Set complaints
	to 1 for people debugging gdb.

	* breakpoint.c, remote-vx.c:  Reword strings printed by
	catch_errors callers.

Wed Sep  4 11:07:50 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* WHATS.NEW:  "history write -> history save".  Doc "write on/off".
	(Fix from kenc@viewlogic.com.)

	Fix some infrastructure to be able to cope with host and target
	machines with different sized basic types (ints, ptrs, etc).
	(Idea from pierre@la.tce.com (Pierre Willard).)

	* values.c (value_from_longest):  Rename from value_from_long.
	Handle pointer types as well as integers, so that targets with
	different pointer sizes from the host can be accomodated.
	* breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
	valarith.c, valops.c, valprint.c, value.h, values.c:  Rename
	uses of value_from_long to value_from_longest.
	* eval.c, findvar.c, printcmd.c, valarith.c, valops.c:  Pass
	the correct pointer type to value_from_long{est}.

	* doc/gdb.texinfo ($_, $__):  Describe types of these variables.

	* remote-vx.c:  Remove obsolete code for calling functions via
	vxworks kludge interface (it referenced value_from_long).

	* valops.c (value_string):  Find malloc with lookup_misc_func, not
	raw search.

Tue Sep  3 18:37:46 1991  John Gilmore  (gnu at cygint.cygnus.com)

	Make writing to files work properly.  (Fixes to BFD are also needed.)

	* core.c (core_open):  Open file ourselves, read or r/w, depending on
	write_files.  Use bfd_fdopenr.  
	* gdbcore.h (write_files):  New variable.
	* exec.c (write_files):  Define variable, add set&show for it.
	(exec_file_command):  Use write_files to open for read or r/write.

	Make shared library reading happen automatically.  These changes
	are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.

	* inferior.h (stop_soon_quietly):  Add to exported variables.
	* infrun.c (child_create_inferior):  call solib hook, if defined.
	(child_attach):  call solib hook, if defined.
	* solib.c:  Include inferior.h.  Add from_tty to so_list as kludge.
	(find_solib):  Use lookup_misc_func rather than hand-rolled.
	(symbol_add_stub):  New stub for catch_errors.
	(solib_add):  Avoid output if !from_tty.  Catch errors rather
	than just calling symbol_file_add and bombing.
	(solib_create_inferior_hook):  Interface with the target process
	to let it read and alloc shared libs, then figure out what it did.

	* core.c (validate_files):  Fix typo, soften warning.  
	(Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)

	* utils.c (fputs_demangled):  Avoid duplicate printing if
	demangling is off.  (Fix from J.T. Conklin <jtc@cayenne.com>.)

	* infrun.c (proceed):  Cast -1 to (CORE_ADDR) before comparing.
	(Fix from pierre@la.tce.com (Pierre Willard).)

	* main.c (catch_errors):  Change argument to a char * from an int,
	since a char * can point to a struct full of glop, but an int
	is not guaranteed to be able to hold a pointer.
	* breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
	breakpoint_re_set_one, breakpoint_re_set):  Adapt.
	* core.c (core_open, solib_add_stub):  Adapt.

Fri Aug 23 14:07:09 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)

	* doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
	more on printsyms. 

	* doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
	"gdb-all.texinfo" 

	* doc/rdl-apps.texi: renamed from rdl-apps.texinfo

	* Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
	reflect above name change

	* WHATS.NEW: correct pointer to refcard.

	* doc/gdb.texinfo: update, fix bugs in "Installing" appendix

Fri Aug 23 01:02:00 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* Makefile.in:  Add config.sub, make doc/rdl-apps.texinfo for
	tar file, add dependencies for referenced doc files.

Thu Aug 22 22:17:06 1991  Stu Grossman  (grossman at cygint.cygnus.com)

	* coffread.c, symfile.c, stack.c:  saberized.

Thu Aug 22 16:20:27 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)

Thu Aug 22 14:05:47 1991  Stu Grossman  (grossman at cygint.cygnus.com)

	* expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
	  cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,

	* configure.in:  Translate three-part names to filenames.

	* README, WHATS.NEW:  Update for gdb-4.0.
	* Makefile.in:  Roll VERSION to 3.99.

Wed Aug 21 18:21:09 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* infptrace.c (KERNEL_U_ADDR_BSD):  Include a.out.gnu.h.
	* i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
	tm-m68k.h, remote-nindy.c:  Change ext_format_XXX structs
	to single structures rather than arrays; when passing
	their address, use &.  This avoids trouble with bdead compilers.
	* mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
	instead.  This avoids portability headaches.
	* mips-tdep.c (mips_do_registers_info):  Only print FP regs if
	asked to.
	* source.c (open_source_file):  Avoid ANSI const bdeath by 
	skipping declaration and then casting result value.
	* tm-hp300bsd.h:  Clarify comment.
	* utils.c (strstr):  Result is const char *; ANSI bdeath.
	* xm-hp300bsd.h:  Define HOST_BYTE_ORDER.  Redefine INT_MIN,
	since system include file defines it differently from "defs.h",
	though the two are equivalent for our purposes.
	* tconfig/hp300bsd:  Add m68k-tdep.o.

Tue Aug 20 16:01:11 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* tconfig/sun*4:  Remove warnings about system assembler.

Mon Aug 19 13:44:46 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* mcheck.c:  Avoid warning about undeclared abort fn.
	* tm-sparc.h (PC_ADJUST):  Avoid calling error() from this;
	it causes recursive calls to error() when used in cleanups.
	To do so requires that we make it a function, so we do.
	* sparc-tdep.c (sparc_pc_adjust):  New implem of PC_ADJUST.
	* utils.c (do_cleanups):  Remove the current cleanup from the
	chain *before* calling it, in case error() is called from it.
	The result won't be pretty, but won't be an infinite loop either.

Mon Aug 19 00:41:04 1991  Michael Tiemann  (tiemann at cygint.cygnus.com)

	* dbxread.c (read_struct_type): Grok anon structs for C++.
	(vb_name, vptr_name): Null terminate these strings.

Fri Aug 16 08:31:03 1991  John Gilmore  (gnu at cygint.cygnus.com)

	Minor bug fixes from BSD Net2 gdb:

	* blockframe.c (get_prev_frame_info):  If FRAME_CHAIN_COMBINE
	returns 0, there is no previous frame.
	* breakpoint.c (commands_command):  If !from_tty, don't call
	input_from_terminal_p().
	* dbxread.c (record_misc_function):  Speed up slightly.
	(compare_psymbols):  Ditto.
	* infcmd.c (do_registers_info):  Take a second argument to
	determine whether to print float registers.  "info registers"
	does not do so anymore.  "info all-registers" does, now.
	* mips-tdep.c, pyr-tdep.c (xxx_do_registers_info):  Take second
	arg and ignore it.
	* tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO):  Pass second arg.
	* inflow.c (initialize_inflow):  Set tflags_ours correctly.
	
	Other fixes:

	* breakpoint.c (bpstat_do_actions):  Use a cleanup to restore
	executing_breakpoint_commands if we are interrupted by error.
	* coffread.c (init_lineno):  Avoid problem with zero-sized linetab
	versus malloc/free.  From: john@labtam.labtam.oz.au (John Carey).
	* core.c (solib_add_stub, core_open):  Call SOLIB_ADD inside a
	catch_errors() so we can setup the frame regardless of whether
	the shared libs work.
	* ieee-float.c (double_to_ieee_extended):  Get exponent from
	right place in little-endian systems.  From John Carey.

Thu Aug 15 18:43:57 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* main.c: Remove unused terminating_signals and catch_termination().
	(long_options):  Terminate with a zero element.
	[Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
	(gdb_readline):  Make call-compatible with readline.
	(init_signals):  Improve comments re vfork vs. signal.

	* utils.c (prompt_for_continue):  Use new gdb_readline().
	If we prompt for continuation, we don't let CR repeat the previous
	command, once we get back to a prompt.  It's too easy to keep
	hitting CR, expecting "--more--" prompts, and have some long
	command start repeating on you.

Tue Aug 13 16:17:56 1991  John Gilmore  (gnu at cygint.cygnus.com)

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

	* core.c (core_open, core_close, core_xfer_memory):  Move
	section table pointers and bfd* into the target_ops.
	(core_open):  Allow errors in shared lib reading, etc.
	(core_files_info):  Describe shared library sections.

	* exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
	exec_files_info, set_section_command):  Move section table
	pointers and bfd* into the target_ops.
	(add_to_section_table):  Add BFD to section table.

	* target.c (target_xfer_memory, target_info):  Pass target to
	xfer_memory and target_info functions.
	* target.h:   ''

	* gdbcore.h:  Move struct section_table.
	* target.h:  New home of struct section_table.

	* solib.c (solib_add):  New argument is the target_ops whose
	section list is to be added to, if any.  Reallocate the
	sections in that target to add any that come from shared libs.
	(throughout) so_sections renamed to sections.
	(solib_xfer_memory):  Deleted.
	* tm-sunos.h (SOLIB_ADD):  Add target argument.
	(SOLIB_XFER_MEMORY):  Delete.

	* core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
	remote-vx.c, remote.c, target.c, target.h:  Remove add_syms vector
	from target_ops.  It's the same on all targets.  Add two section
	pointers to target_ops.

	* stack.c (find_relative_frame):  Dump ancient algorithm for
	"down", just use handy "next" pointers.
	(frame_command):  Don't error if there is no stack; let user
	set one.

	* inflow.c (new_tty_prefork, new_tty):  New prefork routine
	modifies static state in the parent process; new_tty itself
	runs in the child and modifies the child's file descriptors
	to match the saved static state.
	* infrun.c (child_create_inferior):  Call new_tty_prefork,
	fork, then new_tty.

	* infptrace.c (child_xfer_memory):  Add ignored target arg.
	* remote-eb.c (eb_xfer_inferior_memory):  ''
	* remote-nindy.c (nindy_xfer_inferior_memory):  ''
	* remote-vx.c (vx_xfer_memory):    ''
	* remote.c (remote_xfer_memory):   ''.  Rename from
	remote_xfer_inferior_memory.

	* main.c (main):  Only try to attach "corefile" argument if
	it starts with a digit.

	* symfile.c (symbol_reloading):  New "set/show" variable.
	(symbol_file_add):  Shorten message about symbol reading.
	(add_symbol_file_command):  Merge with add_syms_addr_command,
	since this should work on all targets now.
	(stop_whining):  Default to zero, to shut up complaints
	about bad symbol tables on many systems.
	(free_named_symtabs):  Just exit unless symbol_reloading.

	* xm-sun3os4.h, xm-sun4os4.h:  Define BROKEN_LARGE_ALLOCA,
	and add comment explaining shared library screw.

	* source.c:  #if defined => #ifdef.

Thu Aug  8 12:23:19 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* doc/gdbint.texinfo:  Improve doc on porting to new OS's.

Tue Aug  6 17:16:15 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)

	* doc/rdl-apps.texinfo: provide default readline-appendix finder
	(doc/Makefile knows how to make one for local config)

	* Makefile.in: use doc/Makefile for doc targets

	* doc/Makefile: GDB documentation now has its own Makefile
	  doc/refcard.tex: renamed from "gdbrc.tex"
	  doc/.Sanitize: add Makefile; recognize renamed refcard.tex
	  doc/gdbint.texinfo: add markup in "Cleanups" chapter


Fri Aug  2 00:13:06 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* values.c (baseclass_addr):  When reading target memory, use the
	length of the basetype, not the upper type.  We've only malloc'd
	enough space for the basetype, leading to errors in free().

	* expprint.c (print_subexp):  Print UNOP_MEMVAL of an OP_LONG that
	ends up as a function specially, since we know the actual type of
	the pointed-to address.  This (somewhat) fixes display of
	expressions that include misc_function_vector names.  Try `cond 1
	!strcmp("a","b")' then `i b'.

	* infrun.c:  Move DO_DEFERRED_STORES from proceed() to resume().
	The child can be proceeded from inside wait_for_inferior in
	evaluating breakpoint conditions, and DO_DEFERRED_STORES was
	getting skipped in that case.

	* expprint.c (print_subexp):  Use filtered output, since the
	subroutines we call use it, otherwise the output is horribly
	mangled, since output of wrappable stuff comes out late.

	* Makefile.in:  Bump VERSION to 3.98.1

	* infrun.c (child_create_process):  Use execlp to find the
	shell to exec our target program.  This requires some fiddling
	with `environ' since there is no execlpe().

Thu Aug  1 15:35:17 1991  Roland H. Pesch  (pesch at fowanton.cygnus.com)

	* Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
	Minor rearrangement of refcard permits two new make targets--
	gdbrc.dvi	    DVI output for refcard, using CM fonts
	gdbrc.ps	    PostScript refcard, using PS fonts

Wed Jul 31 16:46:21 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* GDB-3.98 release.

	* TODO, Projects, WHATS.NEW, README:  Update for gdb-3.98.
	* Makefile.in (gdb-all.texinfo):  Avoid touching file if M4 dies.

Wed Jul 31 16:35:58 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)

	* doc/gdb.texinfo: last changes for release.
	Minor typo and formatting fixes; incorporated most fixes remaining from
	filed mail commenting on earlier drafts.

	Added warnings: pipes don't work in run command;
	        conditions are converse of assertions;
	      	step over fn without debug info goes to next fn;
		vars may have "wrong" values near fn entrance, exit

	Added example from Kingston on printing repeated nonadjacent values

	Added explicit mention that in Emacs gdb mode C-c and C-z are like
	shell mode for signals

	Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
	doesn't sound so much like its parent "Stopping and Continuing"; also
	moved entries on continue to top of section, so they don't get lost.

	Improved installation directions in appendix, added manual formatting
	instructions 

Tue Jul 30 17:26:39 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* configure.in:  Remove xm.h and tm.h even if we aren't linking
	new ones, so "./configure sun4; ./configure none" does the right
	thing.  Assume that alldeps.mak and depend are already built in
	srcdir, and avoid running "make" (particularly "make depend",
	which involves "gcc") from inside configure.  Build Makefile
	directly rather than building Makefile.conf first.
	* configure:  Regenerate with above changes.
	* Makefile.in:  Use $(BISON) to find bison.  Roll VERSION
	to 3.98.  Revise gdb.tar.Z procedure to produce a file
	called gdb-$(VERSION).tar.Z but which unpacks into a
	directory called "gdb".  Move non-source files out of
	$(SFILES_SUBDIR).  Pretty up alldeps.mak with comments.
	(depend):  Don't try to do "gcc expread.y".
	(expread.o):  Update dependencies by hand.

Mon Jul 29 15:21:09 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)

	* doc/gdb.texinfo:
	Fixed a variety of small typos that prevented info from formatting
	cleanly; altered too-long heading for GPL Appendix, as discussed
	w/RMS; Changed date on cover to July 91.

Fri Jul 26 13:20:02 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)

	* doc/gdb.texinfo:
	(1) Applied some fixes due to comments from Larry Breed (easier ones
	through chapsec 5.2)
	(2) Eliminated use of @footnote---had my doubts about it anyways, and
	it's broken in latest texinfo
	(3) Introduced *some* use of [] for optional arguments, where
	explanation is not simpler by listing cmd w arg and cmd w/out arg
	separately.  Still not using @deffn.
	(4) Dropped in GPL-2.  NOTE: one of GPL-2 or texinfo is broken; a
	couple of headings are too long.  Need patches to texinfo or revision
	to GPL-2.

	* Partial update to README (which still needs work for this
	release!): (1) use of configure corrected for new script, 
                   (2) "make gdb.dvi" and "make gdb.info" mentioned.

Wed Jul 24 06:44:02 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* symtab.c (lookup_symbol):  Don't complain right off about
	no debug symbols; use the misc function vector first.
	(list_symbols):  Use misc function vector to find symbols
	that don't have debug info, and print them.
	(find_pc_symtab):  Temporarily avoid fatal() when psymtab
	PC range doesn't match symtab PC range, as it does on the 
	MIPS because our symtab reading isn't perfect.

	* dbxread.c (dbx_symfile_read):  Make warning about
	"no debug symbols" slightly nicer.

	* source.c (select_source_symtab):  If "main" symbol exists,
	but decode_line_spec can't find line info, don't just return
	a zero; try other source symtabs or give an error.

	* mipsread.c (parse_partial_symbols):  Sort the psymtabs by
	their low addresses first, then rip through fixing high addrs.

	* ns32k-opcode.h (sfsr):  Bugfix from Rune Nerg}rd,
	<runene@ifi.uio.no>.
	(NS32K_SVC_IMMED_OPERANDS):  Reverse the #ifndef.

Tue Jul 23 18:52:43 1991  Roland H. Pesch  (pesch at cygint.cygnus.com)

	* Minor, mostly mechanical, cleanup of doc subdir for clean 
	makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4) 
	and gdb.info (post- texinfo2 makeinfo) generated for distribution.

Sun Jul 21 03:54:52 1991  John Gilmore  (gnu at cygint.cygnus.com)

	Mostly MIPS and general symbol-reading fixups.

	* doc/gdbint.texinfo:  Add documentation on symbol-reading
	interface.

	* mipsread.c:  Remove kludges around #include "ecoff.h".
	Remove redefinitions of a_magic, etc, no longer used.
	(parse_symbol, ):  Convert "Internal:" printfs to complain()ts.
	Fix global overview comments to match symfile.c protocol.
	(mipscoff_new_init):  Eliminate cur_hdr if we have one.
	(mipscoff_symfile_read):  Eliminate unused code.  Avoid
	sorting all the symtabs, when all we have read here is psymtabs.
	The symtabs are sorted as they are created anyway.  Tell
	condense_misc_bunches whether we're mainline.
	(psymtab_to_symtab_1):  Pass filename when recursing, to make
	stack trace more informative.
	(parse_partial_symbols):  Assume cur_hdr as argument.
	(read_mips_symtab):  Don't clobber cur_hdr, so it can be freed.
	Pass cur_hdr implicitly to parse_partial_symbols.  Avoid checking
	the TYPE_NAME of char *, since that's done in symfile.c.
	(free_numargs, parse_symbol, add_symbol, add_block,
	shrink_linetable):  Declare these fns void. 
	(upgrade_type):  Convert tree of if's to switch.  Clean up
	bogus "off == 0" handling with a complaint.  Avoid setting
	field bitpos and bitsize of array with lower and upper bounds.
	Check specified bitsize of elements against their actual type's
	bitsize, and complain if different.  Complain about unknown 
	type qualifiers.
	(parse_fdr):  Don't assume sizeof(char *) == sizeof (struct *).
	(psymtab_to_symtab_1):  Print names of subsidiary files that
	are being read in.  FIXME, we read far too many files.  This code
	is not the problem, the problem is in parse_fdr where the psymtabs
	are set up.
	(cross_ref):  Result should indicate that we used one aux entry
	normally, or two if we encountered a "next" entry.  This used
	to leave the caller pointing at the wrong aux entry.
	(add_symbol):  If overflowed cur_block, reallocate it larger,
	chase all pointers to it, and complain(), rather than clobber memory.
	(shrink_block):  Use xrealloc rather than xmalloc-and-copy.
	(new_field):  Only allocate one field initially, not two.
	Pull ++ out of macro argument.  Simplify.
	(_initialize_mipsread):  Avoid initialization of importd
	global_psymbols and static_psymbols. 

	* symfile.c (psymtab_to_symtab):  Depend on XXX_psymtab_to_symtab
	to properly set pst->symtab; avoid searching for it.
	(symfile_fns):  Improve comments, add a FIXME.
	* dbxread.c:  Update comments to reflect symfile protocol.
	(read_ofile_symtab, end_symtab):  Return the symtab.
	(psymtab_to_symtab_1):  Set pst->symtab.

	* coffread.c (coff_symfile_read):  tell condense_misc_bunches
	whether we're mainline.

	* symfile.h (sym_fns):  Remove unused sym_discard member.
	* coffread.c, mipsread.c, dbxread.c:  Remove XXX_symfile_discard.

	* mtrace.c (mtrace):  Take effect if mallwatch is set, even if
	the environment variable is not.
	* infcmd.c (finish_command):  Use filtered printfs.
	* cplus-dem.c:  Add struct tags to a few unnamed structs.
	* valops.c (value_coerce_array):  Improve comments.
	* valprint.c (type_print_varspec_suffix):  Print array size only
	if greater than zero.
	* m88k-tdep.c:  Shift some lines left by one space, that had
	apparently been trashed at some point.
	* TODO:  More things to do, a few got done.

Thu Jul 18 22:46:05 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* symtab.h (LOC_EXTERNAL):  Eliminate in favor of LOC_STATIC.
	(ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
	comments.
	* dbxread.c (read_dbx_symtab):  LOC_EXTERNAL -> LOC_STATIC.
	* expread.y, findvar.c, symmisc.c:  Ditto.
	* printcmd.c (address_info):  Update printed forms of LOC_
	symbols.  Elim LOC_EXTERNAL.  
	(print_frame_args):  Keep track of param stack offsets before
	re-looking up to find the local register param is kept in.

	* mipsread.c:  Use <symconst.h> and <sym.h> rather than <syms.h>.
	Further integration of mipsread into gdb.  Eliminate unused
	routines, duplicate declarations.  Handle static symbols in 
	psymtabs as well as external symbols.  When reading symtabs,
	insert symbols into the correct block (global, static, or a local
	block).
	(read_mips_symtab, parse_partial_symbols):  Don't pass useless
	"incremental" arg.
	(mipscoff_symfile_read):  Don't call select_source_symtab.
	(parse_symbol):  Use SYMBOL_VALUE_ADDRESS where appropriate,
	rather than SYMBOL_VALUE.
	(parse_external):  Comment clobbering of top_stack.
	(parse_partial_symbols):  Update comments.  Allocate and parse
	static symbols as well as external symbols.  FIXME, enum values
	are not handled in this pass, but should be.  Inline new_psymbol.
	Use SYMBOL_VALUE_ADDRESS.
	(psymtab_to_symtab_1):  Read symbols into global static block
	by default (until enter some function's local block context).
	(sort_blocks):  Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
	(destroy_all_symtabs, new_psymbol):  Eliminate, unused.

	* source.c (select_source_symtab):  Select a source symtab
	from either the symtabs or, failing that, the psymtabs.
	(list_command):  Update error message.
	(forward_search_command, reverse_search_command):  Use getc, not
	fgetc, for speed.  FIXME, add comment about buffers that die if
	overrun by long line.

	* values.c (unpack_field_as_long, modify_field):  Avoid shifting
	by an entire word, which is not portable, if we have a 32-bit
	field.  (Code in dbxread.c already turns such bitfields, if
	aligned, into ordinary ints, but fixing this will help for other
	symbol formats and for future changes.)
	* core.c (core_open):  Handle ANSI const brain death.
	* utils.c (vprintf):  Fix varargs typo.

Sun Jul 14 00:42:53 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* findvar.c (find_var_value):  Handle &function better.
	* TODO:  Document work needed on &fn and &array.
	* printcmd.c (print_address_symbolic):  New arg is the prefix
	to print if a name is printed.
	(print_address_demangle):  Honor "set print address" now.
	Use new arg above to improve spacing of output.
	* valprint.c (val_print):  When printing function pointers,
	print symbolic form too.
	* breakpoint.c (breakpoint_1):  Use new print_address_symbolic.

Mon Jul  8 19:02:46 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* core.c (memory_error):  Reword error msg to mislead less.

	* mips-pinsn.c (print_insn_arg 'd'):  Print $ with reg name.

	* mipsread.c (read_mips_symtab, read_the_mips_symtab,
	parse_partial_symbols): Use newer BFD internals (external_filehdr
	and external_aouthdr), byte-swap the fields that we care about
	before using them, and make the file header data local to
	read_the_mips_symtab rather than global.

Sat Jul  6 01:34:15 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* ns32k-opcode.h (movmw, movmd):  Fix opcodes.  Bug fix
	from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.

	* main.c (command_line_input):  Flush stdout and stderr
	before every call to readline.  This reportedly fixes a bug
	that comes up in Sys V running emacs-gdb and/or xxgdb,
	when stdin/out are pipes or sockets.

Thu Jul  4 14:47:06 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* configure.in, Makefile.in:  Avoid rebuilding "depend" as much.
	Avoid declaring Makefile dependencies, because GNU Make stupidly
	tries to update it if we do.

	* coffread.c:  Revise for minor changes to bfd internal coff
	indexes.

	* configure:  If -template= is given a relative path, make it 
	absolute before recurring in subdirectories.

	* configure, configure.in, Makefile.in:  Install "configure" script
	as replacement for config.gdb.
	* config.gdb, Makefile.dist, Makefile.sdir:  Remove
	* README:  Update for configure, mostly.  FIXME.

	* Add dec3100 as equivalent to littlemips.  Indicate in all host &
	target config files that they are for the host.  When the lines
	get copied into the Makefile, this makes it more obvious what's
	up.

Mon Jun 24 23:49:07 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* sparc-opcode.h (trap opcodes):  Avoid leading spaces or
	tabs, which end up in the disassembler output inadvertently.

Wed May 29 23:01:03 1991  John Gilmore  (gnu at cygint.cygnus.com)

	Make it compile cleanly in an ANSI GCC2 environment.

	* blockframe.c:  <stdio.h>
	* cplus-dem.c:  free takes a void *, ifdef __STDC__
	* dbxread.c (read_huge_number):  avoid gcc2 bug hoisting calc of
	LONG_MAX/radix.
	* defs.h (alloca):  Avoid doing anything if alloca already def'd.
	* stddef.h, stdlib.h:  Remove these files.
	* symtab.c:  Avoid declaring qsort, close.
	* symfile.c:  Avoid declaring close.
	* utils.c (vprintf):  Declare "ap" arg as proper va_alist.	
	* sparc-tdep.c:  Avoid including lots of Sun-host-specific files.

	Assorted other changes.
	* dbxread.c:  include "libaout.h", not "liba.out.h".
	* printcmd.c (print_frame_args):  Set recurse properly for
	indentation of struct and array parameters.
	* valops.c (value_cast):  Allow cast to void.
	* infrun.c (resume):  If NO_SINGLE_STEP, call machine dependent
	single_step() in a target-independent fashion.
	* sparc-tdep.c (single_step):  Don't call ptrace ourselves, just
	set up to be ready to continue.  This makes us target independent.
	* infptrace.c (child_resume):  Remove call to single_step; now
	can single step a SPARC target of any kind.

Wed May 22 18:18:24 1991  Roland H. Pesch  (pesch at fowanton.cygnus.com)

	* Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
	docn into separate sections---basically chapters, plus two loose
	pieces that can be configured to go in different places.  This
	allows GNU m4 to preprocess the manual without coredumping.

	* Makefile.dist: tell TeX where to find texinfo.

Mon May 20 12:15:04 1991  Roland H. Pesch  (pesch at fowanton.cygnus.com)

	* Makefile.dist, doc/gdb.texinfo: respectively create, and use,
	the new target "rdl-apps.texinfo" which captures the Makefile
	variable that records where to find the Readline libraries.

Sun May 19 05:36:59 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* tahoe-pinsn.c:  #include "tahoe-opcode.h", not "opcode.h".
	* tm-tahoe.h (FIX_CALL_DUMMY):  Ignore more parameters.
	* defs.h (const, volatile):  Only define if not already defined.
	* Makefile.dist (gdb.tar.Z):  Create doc subdir w/out CVS/RCS crud.

	* README:  Update for release 3.95.
	* config.gdb:  Don't create readline dir in subdir builds.
	* main.c:  Include with "..." form for non-system include files,
	so "gcc -MM" for "make depend" works.
	Include readline files with "...h" rather than <readline/...h>.
	* mipsread.c:  Include "ecoff.h" rather than "intel-coff.h".

	* coffread.c:  Undo minor damage done by Rich Pixley.  Use
	different internal and external representations of COFF
	data structures.  Use new BFD routines for swapping them in and
	out.
	* symfile.c (free_named_symtabs):  Avoid freeing file names that
	are null or empty.  Old i960 tools seem to produce files that
	claim to have empty names, causing each successive file read
	to blow away the previous one.
	* sparc-xdep.c (deferred_stores):  Repair minor damage by Rich.
	Move deferred_stores to top of file, but don't separate its
	#define's from its variable.  Add commentary.
	* Makefile.dist:  Fix Rich damage; undo "configure" changes in
	favor of keeping the (working) config.gdb.  Move readline
	library up a notch.

Fri May 17 12:49:56 1991  Per Bothner  (via gnu at cygint.cygnus.com)

	* dbxread.c (read_struct_type):  Try to handle g++ version 1 MI
	debug info.
	* infptrace.c (fetch_registers):  no result, since now void.
	* tconfig/news:  target depends on m68k-tdep too.

Fri May 17 14:40:14 1991  Roland H. Pesch  (pesch at fowanton.cygnus.com)

	* Makefile.dist: added readline/inc-*.texinfo to dependencies for
	gdb.dvi target

	* readline/inc-history.texinfo, readline/inc-readline.texinfo:
	applied various small fixes due to or inspired by RMS comments

	* doc/gdb.texinfo: finished using all RMS comments, save those for
	appendices on readline and cmd history (which are in other source
	files) 

Thu May 16 18:06:05 1991  Roland H. Pesch  (pesch at fowanton.cygnus.com)

	* doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
	chapter 9; (2) documented 'break' command's menu mode for
	overloaded names, in response to hgs problem report C++ p-31

Wed May 15 11:02:48 1991  Roland H. Pesch  (pesch at fowanton.cygnus.com)

	* doc/gdb.texinfo: (1) better introductory example; (2) more
	consistent use of @code, @samp, @file, @kbd throughout; small
	cleanups to first three nodes; (3) new "Contributors" node;
	(4) Appendix, Renamed Commands; (5) divert specialized startup
	instructions to "Targets" chapter for generic manuals, while
	leaving them up front for manuals specific to specialized
	environments; (6) apply fixes from RMS comments through chapter 4.

	* pretex.m4: modify explanatory text slightly (and redefine
	"regexp") to keep GNU m4 from complaining.  (It still crashes
	later, but one step at a time...)

Wed May 15 10:32:12 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* readline/readline.c (update_line):  Avoid dereferencing a pointer
	before comparing it to its bounds.  Saber caught this.
	(init_terminal_io):  Don't set BC from the "pc=" termcap variable,
	and only set PC if tgetstr returned non-null.  Saber caught this.

Tue May 14 16:29:53 PDT 1991  Roland Pesch (pesch at cygint.cygnus.com)

	* Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
	stuff for config manual) here where it counts; updated
	to use new subdir structure (gdb/doc/).

	* Makefile: generated from above via 
		    config.gdb none 
	before checkin

	* gdbint.texinfo: added instructions on generating gdb.info* files
	locally for release.  These are ordinary info
	files, formatted from gdb.texinfo (via gdb-all.texinfo, see
	Makefile)---but due to use of texinfo 2, can't count on makeinfo
	to generate these, so we distribute them already formatted.

	* gdb.texinfo: included full Info node and menu crud (as generated
	by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).

	* Makefile: updated "gdb.dvi" target to use M4 preprocessor;
	put in comments-for-future gdb.info target (one day makeinfo will
	work again).

Tue May 14 13:51:36 PDT 1991  Roland Pesch (pesch at cygint.cygnus.com)

	* gdb.texinfo: Updated to include new or old undocumented
	commands, at least the following (perhaps some others I forgot to
	record): info f, info float, info path, info program, info s, info
	set, info source, info terminal, info types, info user, set/show
	print object.  
	Also covered all recent GDB command renames for v4.

Mon May 13 14:57:46 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* mipsread.c:  Rather than keeping count of how many symtabs
	and psymtabs we have, for sorting purposes, count them when
	we need to sort.  This fixes bug in rereading of symbol tables.

Fri May 10 15:43:33 PDT 1991  Roland Pesch (pesch at cygint.cygnus.com)

	* infcmd.c: renamed "info path" to "show paths"
        * gdbrc.tex: documented above.

Wed May  8 04:51:11 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* remote.c:  Fix comments.
	* utils.c (error):  Force out any pending wrap output.

Sat May  4 11:11:07 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* Makefile.dist:  Roll VERSION to 3.95.
	Fix up "saber_gdb" to work again.
	* saber.suppress:  Update.

	* coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
	symtab.h, target.c, target.h:  Lint.
	* core.c:  setup and select frame after reading shared libs,
	else reading shared libs will clobber them.  Lint.
	* utils.c (error):  Force out any buffered wrap text.

Fri May  3 22:01:56 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* remote.c:  Remove decls of memory_insert_breakpoint
	and memory_remove_breakpoint, no longer used.  (Suggestion of
	Jan Norden).

	* Makefile.dist:  use ${subdir} in paths of BFD and LIBIBERTY,
	to make it easier to interface to "configure"'d libraries.

Fri May  3 13:10:01 PDT 1991  Roland Pesch (pesch at fowanton.cygnus.com)

        * valprint.c:  introduce "set p", "set pr", "show p" and "show pr" as

	* copying.awk (_initialize_copying): Rename "info copying" to
	"show copying" and "info warranty" to "show warranty".
	Rename {copying,warranty}_info to show_{copying,warranty}.

	* symfile.c: Rename add_syms_command to add_symbol_file_command.
	(_initialize_symfile, add_syms_addr_command):
	Rename add-syms to add-symbol-file.

Thu Apr 18 18:08:30 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* symfile.h (free_named_symtabs):  Rename from free_named_symtab.
	* symfile.c (clear_symtab_users_once, cashier_psymtab,
	free_named_symtabs):  Move these routines from symmisc.c.
	* symmisc.c (same):  same.
	(free_symtab):  Make non-static.
	* symtab.h (free_symtab):  Declare as exported void fn now.
	* dbxread.c (end_symtab, end_psymtab):  Change comments.
	(initialize_dbxread):  Call dbx_new_init() in case the first
	command is add-symbols.
	* target.c (dummy_target):  Permit add_syms_addr_command.

Sat Apr 13 14:46:07 1991  John Gilmore  (gnu at cygint.cygnus.com)

	Permit symbols to be superseded when new symbol files have
	been read in, particularly for VxWorks.

	* dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
	to the main file, as well as to include files.  Also, put global
	functions into the global psymtab, to make "i fun" work.
	(end_psymtab):  Free named symtabs and psymtabs for a file, once a
	new psymtab for it has been read.
	* coffread.c (end_psymtab):  Free named symtabs and psymtabs for
	a file, once a new symtab has been read for it.
	* mipsread.c:  FIXME.  We need to do the same for MIPS, but it
	looks harder to determine the top-level block before it's been
	queued to the psymtab list.	

	* symfile.c (symbol_file_add):  Use filtered printing and wrap it.
	If we have wiped out any old symbol tables, clean up at end of
	symbol reading.
	(symbol_file_command):  Don't reference symfile_fns if it's zero.

	* symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK):  New
	defines for the blocks of a blockvector that contain global and
	file-static symbols and the first of the smaller scope contours. 
	* symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
	decode_line_1, make_symbol_completion_list):  Use the above.
	* coffread.c (end_symtab, patch_opaque_types):  Ditto.
	* dbxread.c (end_symtab):  Ditto.
	* expread.y (block):  Ditto.
	* mipsread.c (throughout):  Ditto.
	* symmisc.c (free_named_symtabs):  Ditto.

	* symtab.c (list_symbols):  Process the first symbol of the
	static psymbols list.
	(types_info):  Restore this function from its untimely #if 0.
	It's not perfect, but it is better than nothing.
	(_initialize_symtab):  Restore "info types".

Thu Apr 11 05:23:19 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* m68k-stub.c:  Remote stub for 680x0's, created from
	rem-m68k.shar (which is removed).
	* nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
	Remove RCS log stuff now that we use CVS and it blows our diffs.

Wed Apr 10 14:18:06 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* symmisc.c (free_named_symtab):  Make it work, in its current
	kludgy fashion.  Change result to indicate if we blew away bkpts.
	* dbxread.c (end_symtab):  Accumulate result from
	free_named_symtab and print warning if we blew user's state.
	* symfile.h:  free_named_symtab now returns an int.

Mon Apr  8 23:57:43 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* dbxread.c (dbx_symfile_read):  Initialize psymbol list if this
	is the first symbol read, even if not mainline.
	(dbx_psymtab_to_symtab):  symfile might be zero, cope.
	* exec.c (exec_ops):  Add_syms_addr is valid in our tvec.
	(set_section_command):  New command ("section xxx yyy" -- should
	be renamed to "set section xxx yyy" FIXME) which sets the
	base address of a section of the exec file, overriding the
	virtual address that BFD reports.

Fri Apr  5 17:14:39 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* exec.c:  Add add_syms_addr_command to exec_ops, so you can
	load symbols at any address while examining an exec file.

Thu Apr  4 10:09:35 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* tm-i386v.h (FLOAT_INFO):  Don't define it, since the code
	for printing the float info is host-dependent, not
	target-dependent.  FIXME.
	* i386-pinsn.c:  Move #includes to top, remove useless ones.
	* i386-tdep.c:  Don't bother including <.../reg.h> since we
	don't use it (and it doesn't exist on host systems).

	* ieee-float.c (ieee_extended_to_double):  Convert NaN to Inf.
	Convert negative numbers properly.
	(ieee_test):  Make numbers really random; fix format arg.

	* infcmd.c (attach_command, detach_command):  Don't repeat on CR.
	* core.c (core_detach):  Unpush core_ops, which might not be on
	top.  We used to just pop the top, which broke things.  Don't
	need dont_repeat() any more.
	(core_file_command):  Psst!  Don't repeat it.
	* remote-nindy.c (nindy_detach):  Don't need dont_repeat() now.
	* expprint.c (print_subexp):  Avoid switch fallthru on
	BINOP_ASSIGN_MODIFY, so we can print += and such.
	* frame.h:  Fix typo.
	* inflow.c (kill_command):  After killing inferior, print our
	current frame in the core file, if we have one.
	(generic_mourn_inferior):  When inferior dies, either select
	the current frame (in the new target, e.g. core file), or 
	set both the current and selected frames to NULL.

	Changes from Peter Schauer.

	* infptrace.c:  Avoid <sys/ptrace.h> on USG.

	* Make all file names fit in 14 characters (sigh and damn!):
	mv hp300hpux-xdep.c hp300ux-xdep.c
	mv symmetry-xdep.c symm-xdep.c
	mv symmetry-tdep.c symm-tdep.c
	mv convex-opcode.h convx-opcode.h
	mv tm-vxworks960.h tm-vx960.h
	mv tm-vxworks68.h tm-vx68.h
	mv Makefile.srcdir Makefile.sdir
	mv gdb-int.texinfo gdbint.texinfo
	mv remote-sa.m68k.shar rem-m68k.shar
	mv remote-multi.shar rem-multi.shar
	* Makefile.dist, README, config.gdb, convex-pinsn.c,
	tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
	xconfig/hp300hpux, xconfig/symmetry:  Change names to shorter
	names.

	* command.c (user_info_1, user_info):  New command for listing
	the user-defined commands.

Wed Apr  3 15:00:26 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* dbxread.c (really_free_pendings):  Clear file_symbols
	and global_symbols after freeing them; otherwise, running
	this function twice (if it appears twice on the cleanup
	chain), we try to free things twice.

	* dbxread.c (read_dbx_symtab):  Calculate end_of_text_addr
	based on text_addr (the address of text in core), not on addr (the
	offset between text in the .o file and in core).  This change
	is from Peter Schauer.

	* main.c:  Define ALL_CLEANUPS as a cast of zero.
	(return_to_top_level):  Use it.
	(main):  Do all cleanups after each command run as part
	of the gdb startup sequence.  Also do all cleanups before
	entering the command loop, and every time we exit the command
	loop and reenter.  Before, the cleanups from the startup sequence
	were being left undone until the first error!
	(command_loop):  Rename do_nothing cleanup to command_loop_marker
	so we can see it easily when examining the cleanup chain.
	(init_signals):  Add another do_nothing for signal handling.
	(quit_command):  Only try to kill target if it has execution.
	Problems in the target stack got us into a state where
	inferior_pid was nonzero but none of the targets had execution.
	In this state you couldn't exit gdb.

	* dbxread.c:  Two changes from Peter Schauer.
	(echo_command):  Fflush output after an echo command.
	(show_history):  Pass all args to cmd_show_list.

	* utils.c (init_malloc):  Call mtrace to turn on tracing
	if the environment variable MALLOC_TRACE is set to a file name.
	* mtrace.c:  Add source file which provides a log of every malloc,
	free, and realloc to a trace file.
	* mtrace.awk:  Add source file which analyzes the trace file.
	* Makefile.dist (GNU_MALLOC, MALLOCSRC):  Add mtrace.{c,o,awk}.
	(VERSION):  Roll to 3.94.3.

	* breakpoint.c (breakpoint_1):  Add a space to "i watch" output.
	(check_duplicates):  Don't bother with watchpoints.
	(set_raw_breakpoint):  Comment about danger of this routine.
	(watch_command):  Parse and eval all args before calling
	set_raw_breakpoint.

	* solib.c (find_solib):  Avoid error in referencing memory to
	see if any more shared libraries have been added.  This is
	particularly useful if the target has terminated.  Bug reported
	by Peter Schauer.

	Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
	in bringing up 3.94.2 on the Sun-3.

        * Makefile.dist:  Include CFLAGS in rule for cplus-dem.o.
        * breakpoint.c (enable_breakpoint):  Check for valid watchpoint
        expression (in scope) before reenabling watchpoint.
	* signame.c (init_sigs):  Add missing declaration of i, fix
	sys_siglist declaration.
	* source.c (list_command):  Fixed range computation to use
	lines_to_list ().
	* stack.c (backtrace_command):  Do not allow command if target has
	no stack, print informative error message.
	* target.c (target_command):  Do not write into command line
	because this fails if the target command is used in a user defined
	command.  [This change was enhanced by gnu to support any-
	unique-prefix matching on target names.]
	* valops.c (value_struct_elt):  Avoid infinite loop on an
	erroneous attempt to print the member of function (try p main.p).

Mon Apr  1 17:05:45 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* expread.y (name_no_typename):  Avoid reduce/reduce errors
	caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
	Since the GDB parser really doesn't use name_no_typename in a
	name-only context, the parser can't tell the diff between
	names and numbers here.  Avoid allowing a name_no_typename
	to be a NAME_OR_*INT to resolve the conflict.

Sun Mar 31 20:12:07 1991  John Gilmore  (gnu at cygint.cygnus.com)

	Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):

	* valprint.c (val_print_fields):  bitfield printing didn't handle
	byte order.  Indirect through a few more fns to cope.

	* values.c (modify_field):  also cope with byte order.

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.

	* xgdb.c, XGDB-README:  Remove file.  Users can get the much
	better xxgdb.
	* Makefile.dist:  Remove all trace of xgdb.

	* breakpoint.c (breakpoint_1):  Pass demangle arg to
	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.
	* defs.h (strsave):  Declare.

	* 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.

	* target.c (push_target, target_info):  Cast enums to int for < or
	> comparison.

	* stack.c (print_frame_info):  Identify source file & line
	even if we can't print it.

	* xm-vax.h (MISSING_VPRINTF):  No longer missing in Ultrix V4.0.

Sat Mar  9 10:08:20 1991  John Gilmore  (gnu at cygint.cygnus.com)

	Clean up IEEE floating point support.

	* ieee-float.h:  New file.
	* ieee-float.c:  Write real routines to convert between host
	doubles and various target IEEE extendeds.
	* m68k-xdep.c:  Eliminate assembler code for extended floats.
	* xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
	sun2os4,sun3,sun3os3,sun3os4}:  Eliminate use of m68k-xdep.o.
	* tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
	REGISTER_CONVERT_TO_RAW):  Use ieee_extended_to_double and
	double_to_ieee_extended.
	* i960-tdep.c:  Define ext_format_i960.
	* 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.

	Obsolete the "coffstrip" program in favor of using BFD's strip.

	* nindy-share/coffstrip.c:  Remove file.
	* nindy-share/nindy.c (coffstrip):  Routine to run bfd_strip.
	* Makefile.dist:  Remove references to nindy-share/coffstrip.c.
	* tconfig/nindy960:  Remove reference to coffstrip.o.

	* Makefile.dist:  Roll version number to 3.94.1 (not yet final).

Wed Mar  6 09:56:45 1991  John Gilmore  (gnu at cygint.cygnus.com)

	* symfile.h:  Add symfile_bfd, common between dbxread and coffread.
	* 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"
	and ".reg2", and pass both to fetch_core_registers sequentially.

	Revise directory path yet again.

	* source.c (forget_cached_source_info):  Not static any more.
	(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.

	* defs.h (errno):  Add declaration.
	* altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
	hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
	i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
	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.

	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.

	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.

	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,

	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.
	* inflow.c (child_mourn_inferior):  pop child_ops.
	(generic_mourn_inferior):  Use new has_stack flag.
	* 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.
	* dbxread.c:  Quick changes to make it compile with new BFD.
	* 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.

	* inferior.h (attach_flag):  Export.
	* infcmd.c (run_command):  use new target_create_inferior.
	* infrun.c (child_create_inferior):  Don't return result.
	* Makefile.dist (VERSION):  3.91.4.

Fri Nov 23 28:15:38 1990  John Gilmore  (gnu at cygint)

	* breakpoint.c (bpstat_num):  Handle breakpoints which have
	since been deleted, such as temporary breakpoints.
	infcmd.c (program_info):  ditto.

	* core.c (core_file_command):  Display the frame where the core
	dump occurred.

	* main.c:  lint.

	* remote-vx.c (target_command):  Merge in target command from
	targ-vx.c.  A few other cleanups.

	* 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.

	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.

	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.	

Wed Sep  5 18:00:08 1990  John Gilmore  (gnu at cygint)

	Split add_file_command into add_file_command and add_file.
	Make psymtab_to_symtab read in the string table if the file
	is not symfile.
	Two new parameters to read_dbx_symtab and start_psymtab.

	* infcmd.c: Change cont_command to continue_command and "cont"
	to "continue".

Mon May 21 14:41:41 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)

	* breakpoint.c (enable_breakpoint): Get value of watchpoint.

	* defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.

	* values.c (USE_STRUCT_CONVENTION): Check for structures of
	size 1,2,4,8 rather than size < 8.

	* dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
	as necessary, not just once.

	* sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.

Thu May 17 15:04:09 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)

	* {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386

	* tm-news.h: Add CALL_DUMMY_*.

	* tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.

Tue May 15 21:27:12 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)

	* source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.

	* sparc-opcode.h: Change all store floating-point state register
	instructions to have the right match & lose fields.

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.

Tue Jul  3 09:39:18 1990  Michael Tiemann  (tiemann at masham)

	* 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.

Fri Jun 29 01:03:46 1990  Michael Tiemann  (tiemann at masham)

	* 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.
	(start_inferior): Initialize them.

Thu May  3 00:15:11 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)

	* 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.

	* Makefile.dist (pinsn.o): Use PINSN_CC to compile.
	xconfig/3b1 (CC,PINSN_CC): Define.

	* xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.

	* Version 3.90.8

	* breakpoint.c (bpstat_stop_status),
	infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.

	* param.h, tm-88k.h: Define ADDR_BITS_*.
	infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
