+
+	Mainly stuff to improve handling of TYPE_CODE_REF values.
+	* valops.c (value_addr):  If taking the addres of a
+	TYPE_CODE_REF, just cast the object to the corresponding
+	TYPE_CODE_PTR.  This yields correct C++ semantics, and
+	preserves the location information, which has the nice effect
+	that &(&R) given the location containing R.
+	* values.c (value_copy):  Make non-static (used by value_addr).
+	* eval.c (evaluate_subexp_for_address):  Use the default
+	scheme (with value_addr) for a variable if it has TYPE_CODE_REF.
+	* valops.c (value_addr), eval.c (evaluate_subexp_for_address,
+	evaluate_subexp_with_coercion):  Factor out some common
+	expressions into variables, for easier reading.
+	* findvar.c (locate_var_value):  Remove code to handle
+	TYPE_CODE_REF - it should no longer be needed.
+	* valops.c (value_assign):  Do a COERCE_REF on the
+	destination operand, for correct C++ semantics.
+	* valarith.c (value_x_binop):  Ditto:  De-reference C++
+	references in the arguments.
+	* valops.c:  ANSI-fy: bcopy->memcpy, bzero->memset.
+
+Sat Dec 28 11:30:26 1991  Per Bothner  (bothner at cygnus.com)
+
+	* dwarfread.c, coffread.c:  Use INIT_CPLUS_SPECIFIC.
+	* symtab.c (gdb_mangle_name):  Recognize and handle
+	constructors specially.
+	* symtab.c (check_stub_method):  Test for failure from
+	cplus-demangle by calling error() instead of seg-faulting ...
+
+Fri Dec 27 22:21:30 1991  Fred Fish  (fnf at cygnus.com)
+
+	* defs.h:  Add definition of null_cleanup()
+
+	* procfs.c:  Many small changes to add base support for a new
+	"info proc" command (currently only printing of the address
+	space mapping is implemented) and allow iteration over the
+	address space mapping, calling an arbitrary function for each
+	mapping (used for shared library support).
+
+	* solib.c:  Change all ifdefs that checked for "sun" to check
+	for "!SVR4_SHARED_LIBS" instead.  Rewrite lookup_base() to
+	handle locating the debug base address even when not currently
+	stopped at the dynamic linker entry point.
+
+	* utils.c:  Add null_cleanup() as a known function that does
+	nothing to serve as a base for possibly long cleanup chains
+	with no specific "first cleanup" to serve as an anchor.
+
+	* xm-sysv4.h:  Add define of SVR4_SHARED_LIBS
+
+Fri Dec 27 10:11:33 1991  Per Bothner  (bothner at cygnus.com)
+
+	* arm-opcode.h, m88k-opcode.h, pn-opcode.h, np1-opcode.h,
+	pyr-opcode.h, tahoe-opcode, vax-opcode.h:  Removed -
+	these are all essentially the same as the versions
+	in ../include/opcode.  The remaining *-opcode.h here
+	are not quite so obviously the same, and need study.
+	* arm-pinsn.c, gould-pinsn.c, m88k-pinsn.c, pyr-pinsn.c,
+	tahoe-pinsn.c, vax-pinsn.c:  Change so these include
+	opcode/FOO.h (actually ../include/opcode/FOO.h)
+	instead of the recenntly departed opcode-FOO.h files.
+	* sparc-pinsn.c:  Now that we're using the much tighter
+	opcode table in ../include/opcode/sparc.h, we shouldn't
+	need to sort the opcodes before dis-assembly.
+
+	* symtab.h, symmisc.c:  Make cplus_struct_default be const.
+	* symtab.h, buildsym.c:  Add and use INIT_CPLUS_SPECIFIC macro.
+	* symmisc.c:  Remove unused 'nfields' variable.
+	* buildsym.h:  Add extern decl of unknown_symtype_complaint,
+	since it used used by partial-stab.h (included two places).
+	* partial-stab.h:  Re-arrange DBXREAD_ONLY #ifdefs so that
+	we should never hit the default case (until new stab codes
+	are added).  Hence, we can leave the complaint in the
+	default case in even when DBXREAD_ONLY is off.
+	* partial_stab.h: Recognize a pair of N_SO stabs (one for the
+	directory, one for the filename proper) without peeking ahead.
+	* dbxread.c, mipsread.c: Because of previous change, don't need
+	ugly CHECK_SECOND_N_SO macro.
+	* buildsym.h, dbxread.c, mipsread.c:  Make next_symbol_text a
+	macro that invokes a function pointer in next_symbol_text_func.
+	* mipsread.c:  Added comments various places to
+	explain what is going on.
+	* mipsread.c (parse_symbol):  Support the new (SGI-specific?)
+	symbol types stStruct, stUnion, and stEnum.
+	Also, some fixes in the code for dealing with tags.
+	* mipsread.c:  Change handling of startup_file_start and _end
+	- now just use the textlow and texhigh of a psymtab
+	to check if we've found the startup-file.
+	* mipsread.c:  Replace s_idx by global cur_sdx in many places.
+	This is so mips_next_symbol_text can get at it.
+
+Thu Dec 26 19:52:01 1991  Fred Fish  (fnf at cygnus.com)
+
+	* dbxread.c, symmisc.c:  Move add_psymbol_to_plist() from
+	dbxread.c to symmisc and change name to add_psymbol_to_list.
+	Ditto for add_psymbol_addr_to_plist().  Also expand their
+	body to not use ADD_PSYMBOL_VT_TO_LIST.
+
+	* dwarfread.c:  Remove add_psymbol_to_list() and convert usages
+	to the ADD_PSYMBOL_TO_LIST macro.
+
+	* ieee-float.c:  Change "#ifdef DEBUG" to "#ifdef IEEE_DEBUG"
+	to avoid collision with the DEBUG for ADD_PSYMBOL_VT_TO_LIST.
+
+	* partial-stab.h, symfile.h:  Move definitions of the macros
+	ADD_PSYMBOL_TO_LIST and ADD_PSYMBOL_ADDR_TO_LIST from
+	partial-stab.h to symfile.h.  They aren't stab specific.
+	Change ADD_PSYMBOL_VT_TO_LIST to use memcpy rather than strncpy.
+
+Tue Dec 24 11:38:08 1991  John Gilmore  (gnu at cygnus.com)
+
+	* Makefile.in:  Roll VERSION to 4.3.2.
+
+Mon Dec 23 13:54:35 1991  Per Bothner  (bothner at cygnus.com)
+
+	* m68k-opcode.h, mips-opcode.h, sparc-opcode.h:  Deleted.
+	* m68k-pinsn.c, mips-pinsn.c, sparc-pinsn.c:
+	Include <opcode/FOO.h> instead of <FOO-opcode.h>.
+
+	* symtab.h, symtab.c, coffread.c, dwarfread.c, symmisc.c,
+	dbxread.c:  The TYPE_CPLUS_SPECIFIC structure is now only
+	allocated when it is needed.  Until it is needed, it points
+	to a shared statically allocated structure.
+
+	* buildsym.h, buildsym.c, dbxread.c: Remove the kludgy code
+	in read_ofile_symtab to recognize two initial N_SO stabs,
+	and let process_on_symbol handle it.  This is cleaner, more
+	efficient, and lets mipsread.c share the same code.
+
+	* symfile.h, partial-stab.h:  Move ADD_PSYMBOL_VT_TO_LIST
+	and related macros to here ...
+	* dbxread.c: ... from here.
+	* symmisc.c:  Move the "overflow" handling from
+	ADD_PSYMBOL_VT_TO_LIST macro into new function extend_psymbol_list.
+	* dwarfread.c:  Re-write add_psymbol_to_list to use
+	ADD_PSYMBOL_VT_TO_LIST macro.
+
+	* mipsread.c: Extend mipsread.c to handle stabs-style symbols
+	encapsulated in ecoff symbols.  This enable full g++ debugging.  
+	* partial-stab.h:  Move the code for pre-scanning symbols
+	and building psymtabs to an include file, out from dbxread.c.
+	This way, the same code can also be used by mipsread.c.
+	* dbxread.c, buildsym.h:  Various changes to allow some functions
+	to be used by mipsread.c (also some arguable stylistic changes).
+
+	* tm-mips.h:  Define BLOCK_ADDRESS_ABSOLUTE, at least for now,
+	since mips-tfile puts relocatable addresses into LBRAC/RBRAC
+	stabs.
+
+	* mipsread.c:  Replace code to handle ambiguous tag blocks.
+	Instead of allocating a TYPE_CODE_UNDEF, guess (by looking
+	at types and offsets) if a tag is a struct, union, or enum.
+	Still patch it later if we find out for sure.
+	* mipsread.c:  In various ways, replace Forin's
+	ideo-syncratic code by code that fits better with the
+	rest of gdb, for both stabs-based and ecoff-based symtabs.
+	E.g.  use end_psymtab; don't do extra passes over FDR table to
+	pre-partition global data; don't use external symbols to
+	create static/global symbols (just put them in the
+	misc_vector); use ADD_PSYMBOL_TO_LIST macro; don't
+	sort psymtabs or symtabs; use obstacks more.
+
+	* symtab.c, mipsread.c, dbxread.c, buildsym.c:
+	ANSIfy: Replace bcopy by memcpy, bzero by memset.
+
+Sun Dec 22 19:31:04 1991  Fred Fish  (fnf at cygnus.com)
+
+	* solib.c (locate_base):  Fix uninitialized variable that was 
+	causing return of random value to callee.
+
+	* config/mh-amix, config/mh-i386v4:  Change to find alloca by
+	compiling and linking alloca.c, even when it is not strictly
+	required.  Also arrange to link with -ltermlib rather than
+	-ltermcap.
+
+	* Makefile.in:  Move TERMCAP definition to prior to inclusion
+	of host makefile fragments so it can be overridden.
+
+Fri Dec 20 16:33:39 1991  John Gilmore  (gnu at cygnus.com)
+
+	* xcoffread.c (read_symbol_lineno):  Logic error in incrementing
+	symbol table entry number.  (From Metin Ozisik.)
+
+Fri Dec 20 11:36:38 1991  Fred Fish  (fnf at cygnus.com)
+
+	* config/mh-i386v4:  Change XM_CLIBS to "-lc /usr/ucblib/libucb.a"
+	so compiles with native compilers (without builtin alloca) can
+	pick up the version from the bsd emulation library.  However, we
+	search the standard C library first so we don't pick up lots of
+	other broken stuff from libucb.a, that we *don't* want.
+
+	* configure.in, tm-amix.h, tm-i386v4.h, xm-amix.h, xm-i386v4.h:
+	Change svr4 references to sysv4.
+
+	* source.c:  Move declaration of external function index to
+	front of file so it is in scope for all references.
+
+	* utils.c (error, fatal):  Make definitions consistent with
+	defs.h declarations (declared as "volatile void").
+
+Fri Dec 20 10:55:36 1991  John Gilmore  (gnu at cygnus.com)
+
+	* rs6k-opcode.h:  Bugfix sfe and stbrx.  By Al Kossow.
+
+Wed Dec 18 17:09:06 1991  Stu Grossman  (grossman at cygnus.com)
+
+	* command.h, defs.h, eval.h, expression.h, remote-sa.sparc.c,
+	sparc-tdep.c, symtab.h, target.h, value.h, vx-share/ptrace.h,
+	vx-share/xdr_ptrace.h, vx-share/xdr_rdb.h:  ANSIfy enums.
+
+Mon Dec 16 12:31:46 1991  Fred Fish  (fnf at cygnus.com)
+
+	* config/mt-amix, config/mt-i386v4:  Add solib.o to TDEPFILES
+	for these SVR4 systems.
+
+	* symfile.c (symbol_file_add):  When verbose is set, print
+	the names of files from which symbols are being loaded, as
+	when from_tty is true.
+
+	* solib.c:  Completely reorganized (rewritten) to support
+	SVR4 shared libraries in a manner very close to the original
+	SunOS implementation.  This support is expected to change and
+	become more general at some future time.  The SVR4 version
+	does not yet work for attached processes, for example.
+
+	* dwarfread.c:  Arrange in dwarf_build_psymtabs() for the 
+	relocation address to be valid whether or not symbols are
+	being read from a shared library or an executable.  Use the
+	relocation address recorded in the psymtab when reading
+	full symbol tables (in read_ofile_symtab).  Ensure that the
+	relocated address ranges are recorded in partial symtabs.
+
+	* elfread.c:  Add new function elf_interpreter() to return the
+	string from the ELF ".interp" section.  This is the interpreter
+	that the kernel tries to run and feed the executable to.
+	Expand arguments to record_misc_function to include a type arg.
+	Modify elf_symtab_read() to supply the type arg, and to do symbol
+	relocations for symbols read in from shared libraries.
+
+	* procfs.c:  Add new functions proc_base_address() and
+	proc_address_to_fd(), used by shared library support.
+
+	* tm-svr4.h:  Add macros to support SVR4 shared libraries.
+	Definitions for SOLIB_ADD, SOLIB_CREATE_INFERIOR_HOOK,
+	CLEAR_SOLIB, and DISABLE_UNSETTABLE_BREAK.
+
+Fri Dec 13 20:11:26 1991  John Gilmore  (gnu at cygnus.com)
+
+	* infrun.c, remote-eb.c, remote-nindy.c, remote-vx.c:  Remove
+	unused START_INFERIOR_HOOK.
+
+	* remote-eb.c:  Change timeout to 24 seconds (*10 fits in byte)
+	to account for slow loading from floppies.
+	(eb_create_inferior):  New fn, from eb_start and
+	nindy_create_inferior.
+	(eb_close):  Only use log_file if nonzero.
+	(eb_xfer_inferior_memory):  If not writing, then read!
+	(eb_read_inferior_memory, eb_write_inferior_memory):  Return length.
+	(eb_kill):  A new no-op.
+	(eb_mourn_inferior):  Remove breakpoints, then generically weep.
+
+Fri Dec 13 16:09:23 1991  Fred Fish  (fnf at cygnus.com)
+
+	* breakpoint.c, findvar.c, infrun.c, putenv.c, stack.c:  Fix
+	miscellaneous comparisons of integer with NULL that elicit
+	compiler warnings about comparison of integer with pointer, when
+	NULL is ((void *) 0) rather than just a bare 0.
+
+Wed Dec 11 13:02:58 1991  John Gilmore  (gnu at cygnus.com)
+
+	* breakpoint.c (breakpoint_re_set_one):  Disable each breakpoint
+	while we reset it, in case of problems.  Print breakpoint number
+	in error messages.
+
+	* buildsym.c (read_struct_type):  Avoid sun3 compiler bug with
+	foo[--n].
+
+	* source.c (find_source_lines): If getting file mod time fails,
+	don't warn.
+
+	* target.c (target_xfer_memory):  If errno is set, return it,
+	rather than EIO.
+
+Tue Dec 10 04:07:22 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
+
+	* Makefile.in: infodir belongs in datadir.
+
+Sun Dec  8 21:13:33 1991  Michael Tiemann  (tiemann at sphagnum.cygnus.com)
+
+	* symtab.h (struct fn_field): Add new fields `is_private',
+	`is_protected', `is_stub', making room by reducing the size of
+	`voffset'.
+	(struct fn_fieldlist): Delete the fields `private_fn_field_bits'
+	and `protected_fn_field_bits'.
+	(TYPE_FN_{PRIVATE,PROTECTED}_BITS): Deleted.
+	(SET_TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
+	(TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
+	(TYPE_FN_FIELD_{STUB,PRIVATE,PROTECTED}): New macros.
+	* valops.c, valprint.c, symtab.c: All callers updated.
+
+	* buildsym.c (read_struct_type): Delete the `visibility' field
+	from `struct next_fnfield', and rework code so that visibility
+	info is stored into the fn_field directly.  Also, hacked to set
+	TYPE_FN_FIELD_STUB for both static and normal member functions.
+
+Sat Dec  7 18:13:11 1991  Fred Fish  (fnf at cygnus.com)
+
+	* i386-tdep.c:  Fix a problem on i386 systems where buffered code
+	stream access was failing to take into account the minimum size
+	granularity of the code section.  For now, the buffering is simply
+	disabled.  There is a similar problem in the i386 disassember code
+	that has not yet been fixed (FIXME).
+
+	* gmalloc.c:  Use macros to hide some of the ugly casting required
+	in the previously applied fix for pointers with high bits set.
+
+Sat Dec  7 16:49:35 1991  John Gilmore  (gnu at cygnus.com)
+
+	* Makefile.in:  Roll VERSION to 4.3.1.
+
+Sat Dec  7 04:12:35 1991  John Gilmore  (gnu at cygnus.com)
+
+	GDB-4.3 release!
+
+	* Makefile.in:  Roll VERSION to 4.3
+	* README, TODO, WHATS.NEW, depend:  Update.
+
+	* inflow.c (terminal_inferior):  Avoid error msg if attached.
+
+	* gmalloc.c:  Fix bug that causes malloc & free to
+	fail on systems where pointers have the high bit set (0x800efcf0
+	for example).  The problem is that the difference between two
+	pointers is a signed integer, so the computation
+
+	        (char *) 0x800efcf0 - (char *) 0
+
+	yields a negative value.  The sign of the result of the modulus
+	operator is machine dependent for negative operands, thus it is
+	possible for it to end up negative.  From Fred Fish.
+
+Sat Dec  7 00:00:15 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
+
+	* Makefile.in: install using INSTALL_PROGRAM and INSTALL_DATA.
+	  added clean-info.  added some standards.text support and made it
+	  look like our other Makefiles.
+
+	* configure.in: mark this directory target dependent.  configure
+	  now runs entirely in objdir so make existence tests and
+	  references against ${srcdir}.
+
+Fri Dec  6 08:30:36 1991  Fred Fish  (fnf at cygnus.com)
+
+	* dwarfread.c (enum_type, struct_type):  Fixes for opaque and
+	anonymous enumerations, structures, and unions.  Now passes all
+	the current gdb test suite tests.
+
+Thu Dec  5 22:46:13 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
+
+	* Makefile.in: idestdir and ddestdir go away.  Added copyrights
+	  and shift gpl to v2.  Added ChangeLog if it didn't exist. docdir
+	  and mandir now keyed off datadir by default.
+
+Thu Dec  5 21:53:21 1991  John Gilmore  (gnu at cygnus.com)
+
+	* symtab.c (decode_line_1):  If SKIP_PROLOGUE leaves us in
+	mid-line, be more careful about possibly advancing to the next line.
+
+Thu Dec  5 18:59:51 1991  Michael Tiemann  (tiemann at cygnus.com)
+
+	* cplus-dem.c (cplus_demangle): Call `string_need' when
+	null-terminating a partially-computed string.
+
+Thu Dec  5 18:19:43 1991  Fred Fish  (fnf at cygnus.com)
+
+	* dwarfread.c (enum_type):  Build a correct TYPE_NAME, add a
+	symbol to the symbol table for each member of the enum.
+
+	* dwarfread.c (struct_type):  Build a correct TYPE_NAME.
+
+	* dwarfread.c (add_enum_psymbol):  New function to extract enum
+	member names and add them to the partial symbol table while
+	building partial symbol tables.
+
+Thu Dec  5 17:31:05 1991  John Gilmore  (gnu at cygnus.com)
+
+	* symtab.c (check_stub_method):  Must allocate two extra argument
+	slots (one for `this', one for arglist terminator).
+
+Thu Dec  5 10:51:05 1991  Fred Fish  (fnf at cygnus.com)
+
+	* inflow.c (child_terminal_info): Supply missing '"' character.
+
+	* buildsym.c (define_symbol):  Supply missing parenthesis.
+
+Thu Dec  5 03:34:21 1991  John Gilmore  (gnu at cygnus.com)
+
+	* coredep.c (fetch_core_registers):  Fencepost error.  Fixed by
+	Jay Lepreau <lepreau@cs.utah.edu>.
+
+	* inflow.c:  Remember whether GDB has a terminal.  Avoid switching
+	terminals back and forth if we don't have one.
+
+	* c-exp.y (parse_number):  Zero is not an unsigned int constant!
+	* dbxread.c (read_dbx_symtab):  Enum type numbers can be in (1,2) form.
+
+	Improve type parsing.
+	* buildsym.c (define_symbol, read_range_type): Add
+	long_kludge_name that passes the names of range types being
+	defined, down to where we must choose between 'int' and 'long'
+	variants.  This fails on Sun C anyway since the compiler itself is
+	confused between int and long.
+	(read_array_type, cleanup_undefined_types):  Correct the size of
+	array type whose element-type size isn't immediately known.
+
+	Early preparation to blow away many builtin types, building them
+	on the fly as needed.  Don't compare types to builtin types with
+	==; examine the relevant fields instead.
+	* coffread.c (process_coff_symbol: C_ARG, C_REGPARM):  Avoid ==.
+	* buildsym.c (define_symbol, case 'p'):  Avoid ==.
+	* valops.c (value_arg_coerce):  Avoid ==.  Don't assume host and
+	target types are the same.
+	* valprint.c (val_print):  I finally understand arrays, remove FIXME.
+
+	* symmisc.c (printpsyms_command):  Reduce redundancy, and put all
+	addresses in GDB itself into parens for easy cleanup and diffing.
+
+Wed Dec  4 21:05:30 1991  Fred Fish  (fnf at cygnus.com)
+
+	* dwarfread (enum_type):  Arrange for the order of enumeration
+	members to match the source code order; not the order in the
+	Dwarf information, which is explicitly reverse order.
+
+Wed Dec  4 18:24:39 1991  John Gilmore  (gnu at cygnus.com)
+
+	* main.c (input_from_terminal_p):  Check whether GDB has a
+	terminal at all.
+	(initialize_main):  Revise doc for `set editing'.
+
+Wed Dec  4 15:36:39 1991  Fred Fish  (fnf at cygnus.com)
+
+	* dwarfread.c (struct_type):  Handle structures and unions which
+	contain DIE's other than just member dies.
+
+Wed Dec  4 01:59:05 1991  John Gilmore  (gnu at cygnus.com)
+
+	* symfile.c (reread_symbols):  Avoid kludging mtime_set, now that
+	BFD is fixed.
+
+Tue Dec  3 17:24:57 1991  John Gilmore  (gnu at cygnus.com)
+
+	* Makefile.in:  VERSION 4.2.96.
+
+	* main.c (initialize_main):  Revise command descriptions.
+	* command.c (show_user):  `info user' -> `show user'.	
+	* symtab.c (_initialize_symtab):  Typo in `info types' desc.
+
+	* coffread.c (coff_symfile_read):  Avoid select_source_symtab,
+	since it is not needed and can cause errors when examining ".o"s.
+	(read_coff_symtab, decode_base_type):  Use complain, not printf.
+	Print symbol name, not its number.
+	Remove "#if defined(clipper) #define BELIEVE_PCC_PROMOTION", which
+	someday should go in a clipper target config file.
+
+	* symfile.c (compact_misc_function_vector):  Handle empty vector.
+	(complain, clear_complaints, syms_from_objfile):  Fix complaint
+	formatting.
+	* xcoffexec.c:  Change syms_from_objfile caller.
+
+	* sparc-xdep.c:  Force tm-file as tm-sparc.h, to make it compile
+	when configured for cross debugging.  FIXME, this needs a more
+	general solution.
+
+Mon Dec  2 11:04:05 1991  Per Bothner  (bothner at cygnus.com)
+
+	* mips-tdep.c (init_extra_frame_info):  Float register
+	'i' has gdb-internal number 'FP0+i', not '32+i'.
+	* mipsread.c (new_symbol):  Translate g++ special
+	symbol "$t" to "this".
+
+Sat Nov 30 21:29:55 1991  Steve Chamberlain  (sac at cygnus.com)
+	Changes due to include file renaming:
+
+	* xcoffread.c:	internalcoff.h	->coff/internal.c,

+	helpful compilers for anonymous structs, unions, and enums.
+
+	* c-exp.y, m2-exp.y:  Add defines for yymaxdepth, yy_yys, and

+
+	* procfs.c:  Move inclusion of defs.h to before param.h, as in

+
+	* m68k-tdep.c (m68k_skip_prologue):  Add generic m68k support for
+	skipping function prologues, ala the other cpu families (i386,
+	mips, m88k, etc).  Add the ability to skip movm and fmovm

+
+	* source.c (open_source_file):  If openp fails, try again
+	using just the base (non-directory) part of the filename.
+	This solves various annoying problems, such as when the
+	source was compiled with an absolute pathname - and the
+	source files have moved.  Or if the source was compiled
+	using a relative pathname, it can be more convenient
+	to just specific the source directory to the dir command.
+
+Mon Nov 18 00:04:41 1991  Fred Fish  (fnf at cygnus.com)
+
+	* cplus-dem.c (munge_function_name):  Add missing third arg to

+	record_misc_function().  Remove calls to init_misc_bunches()
+	and condense_misc_bunches(), these are now done in elfread.c.
+
+	* elfread.c:  Add support for reading bfd canonical symbol tables
+	and generating misc function vector entries for global and
+	absolute symbols.  Do calls to init_misc_bunches() and
+	condense_misc_bunches() where they will enclose all calls to
+	record_misc_function(), including those in dwarfread.c.
+
+Thu Nov 14 17:02:11 1991  Roland H. Pesch  (pesch at cygnus.com)
+

+
+	* tm-delta88.h:  Dump all the tdesc stuff.

+	* eval.c (parse_and_eval_type), value.h:  New function,

+	* expprint.c (print_subexp, UNOP_MEMVAL case):  Lint.
+	* inflow.c (new_tty):  Use USE_O_NOCTTY #define.
+	* language.c, printcmd.c (print_scalar_formatted), signame.c,
+	stack.c:  lint.
+
+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 10:58:16 1991  Mark Eichin  (eichin at cygnus.com)
+
+	* cplus-dem.c (cplus-demangle): added support for templates, static
+	data, and the new (correct) mangling for destructors.
+
+	* dwarfread.c: (dwarfwarn): created a varargs version of
+	dwarfwarn, for non __STDC__ compilers.
+
+	* c-exp.y: (yylex): added match for "template" token.
+	(typebase): added TEMPLATE name '<' type '>' clause, for explicit
+	specification of template types.
+
+	* symtab.c: (lookup_template_type): new function for finding
+	templates in symbol table.
+	(type_name_no_tag): changed to explicitly check for s/u/e at the
+	beginning of the symbol - if it is a template, none of these will
+	be there (but the name will still contain spaces.)
+
+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
+

+	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.

+
+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.

+
+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.

+
+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

+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.

+
+	* 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

+	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.

+	cmd.  New host/target configs.
+
+Fri Sep 20 15:46:00 1991  Roland H. Pesch  (pesch at cygnus.com)
+
+	* doc/Makefile: generate aux version-no file doc/gdbVN.m4
+	from main Makefile.in version definition

+
+	* 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,
+	new-target, and new-config chapters; fix minor typos; come closer
+	to usual GNU markup conventions for @file @samp @code @var.
+
+Thu Sep 19 17:04:12 1991  Per Bothner  (bothner at cygnus.com)
+
+	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.

+
+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.

+
+     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.
+

+
+     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,

+     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

+
+     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.
+
+Thu Aug  8 14:17:22 EDT 1991
+
+	main.c
+	printcmd.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

+
+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.c (find_solib):  Avoid memory access if _DYNAMIC is zero.
+	(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.

+
+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.

+	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.
+	* remote-vx.c (symbol_stub, add_symbol_stub, callers):  Adapt.
+
+Wed Aug 28 18:18:05 1991  John Gilmore  (gnu at cygint.cygnus.com)

+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,

+
+	* doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
+	"gdb-all.texinfo" 
+
+	* doc/rdl-apps.texi: renamed from rdl-apps.texinfo

+
+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,

+
+Thu Aug 22 02:02:26 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	Install new configuration scheme for GDB and friends.
+
+	* config.sub:  Translate ordinary names to three-part names.

+	* configure.in:  Translate three-part names to filenames.
+
+	* README, WHATS.NEW:  Update for gdb-4.0.

+
+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)

+
+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++.

+	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)
+

+
+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.

+
+	* 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

+
+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...)

+
+	* 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

+	* 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)

+
+	* 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
+	aliases for set/show print.

+
+	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.

+
+	* symtab.c (list_symbols):  Process the first symbol of the

+	(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 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

+	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.

+	(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.

+	* 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.

+	* 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.

+
+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.

+	(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

+	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.

+
+	* 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.

+
+	* am29k-tdep.c:  Add contribution line.
+	(examine_prologue):  Cache information about function prologues in

+
+	* 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;

+	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,

+	saved value over the current value in the topmost frame.
+	Cache result in the frame info to avoid performance hair in
+	callers.

+	(_initialize_i960):  Actually call check_host.
+
+	* ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):

+
+	* infrun.c (normal_stop):  Make global, not static, for vx_attach.

+	(child_files_info):  Clean up message a bit.

+
+	* 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.

+	have_core_file_p in favor of target_has_stack or
+	target_has_execution.
+	(print_frame_args):  Handle LOC_LOCAL_ARG.  Eliminate duplicate

+	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.

+	(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.

+	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.

+	(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.

+	(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.

+
+	* TODO:  A woman's work is never done.

+	REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
+	* tconfig/i960:  FIXME.  Half-merge, produce warning if config'd.
+
+	Changes to generalize the VxWorks RPC protocol slightly, to handle
+	i960 as well as 68000.
+
+	* vx-share/dbgRpcLib.h (VX_SOURCE_STEP):  Add.
+	* vx-share/reg.h:  Produce i960 regs #ifdef I80960
+	* vx-share/xdr_ptrace.c:  Skip FPA registers if 960.
+	* vx-share/xdr_rdb.h:  Add SOURCE_STEP struct and xdr decl.
+	* vx-share/xdr_rdb.c:  Add xdr_SOURCE_STEP routine.
+	* vx-share/xdr_regs.c:  Add xdr_regs, xdr_fp_status, xdr_ext_fp
+	for i960.  Change xdr_vectors to xdr_opaques for 68k registers,
+	so they will move in target byte order rather than network
+	byte order (happens to be the same).	
+
+Mon Feb 25 03:41:44 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	* tm-convex.h (END_OF_TEXT_DEFAULT):  Remove #if 0'd block.
+
+Sun Feb 24 00:55:53 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	* am29k-pinsn.c, 
+	Add contribution lines to various files, showing where they
+	came from.
+
+	* breakpoint.c (break_insn, check_break_insn_size,
+	read_memory_nobpt):  Remove to mem-break.c.
+
+	* xm-*.h, param-no-tm.h, tm-29k.h, valprint.c:  Change BYTE_ORDER to
+	HOST_BYTE_ORDER.
+
+	* tm-29k.h (STAB_REG_TO_REGNUM):  Warn user if symbol table
+	entry has bad register number.  This change is not
+	tested in this release, FIXME.
+
+	* frame.h:  Eliminate Frame_unknown in favor of a simple zero.
+	tm-vax.h:  Ditto.
+
+	* value.h:  Force value's contents field to be aligned to hold
+	at least a double or a long long (if supported).  This avoids
+	doing bcopy's in and out of the contents field.
+
+	(step_1):  Avoid coredump under obscure circumstances when we
+	have no frame.
+
+	* symtab.h (misc_info):  Add field to misc function vector for
+	any kind of cached information the target code desires.  AMD
+	29000 uses this to avoid repeating examine_function_prologue's.
+
+	* coffread.c:  Lint.  Remove static symfile, read_section_header.
+	core.c (have_core_file_p):  Lint: remove.
+	expprint.c (print_subexp):  Lint.
+	infptrace.c, valops.c, valprint.c:  lint.
+
+	Roll in changes from vxgdb-5.0.1:
+
+	* symtab.h:  Comment byte order of each address class.  Add
+	LOC_LOCAL_ARG for frame-relative args (960).
+	expread.y:  Use LOC_LOCAL_ARG where LOC_ARG is used.
+	symtab.c, symmisc.c:  ditto.
+	
+	* infrun.c (init_wait_for_inferior):  Clear stop_signal.
+
+	* remote.c (remote_resume):  Error if resume with a signal.
+
+	* symfile.c (prim_record_misc_function):  Clear misc_info.
+	(fill_in_vptr_fieldno):  Check stub type of arg.
+
+	* valops.c (value_cast):  Avoid looking up names of types whose
+	name we don't know, to prevent coredump.  Sun CC produces typedef
+	rtx and the name of *rtx is zero...
+
+Mon Feb 18 21:16:25 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	Roll in changes from final AMD 29000 port (Tiemann).
+
+	tconfig/am29k:  Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
+	for ../include/a.out.encap.h.  This might not work now that BFD
+	is separately compiled.  Instead, BFD support for encap will have
+	to translate machine type 29k into the right COFF_MAGIC.
+	
+	* infcmd.c: Remove references to inferior_pid that aren't used
+	in actual ptrace calls; use target_has_execution, etc.
+	(have_inferior_p):  Remove function.
+	(program_info):  Print target info rather than "process number";
+	avoid gratuitous messages unless from_tty.
+	(run_stack_dummy, finish_command):  Set proceed_to_finish.
+	infrun.c: Remove inferior_pid refs.  Decl & init proceed_to_finish.
+	main.c:  Lint.  Lose have_inferior_p().
+	inferior.h (have_inferior_p):  Remove, lint.
+	(proceed_to_finish):  Add flag to ask that all regs be saved
+	by normal_stop, for the few commands that need it, speeding up
+	serial I/O.  Add comments to stop_registers.
+
+	* remote-eb.c:  Remove newline from breakpoint message we grep
+	for.  Never time out when running the user program.
+	
+
+
+Wed Feb 13 15:34:40 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	Roll in changes from vxgdb-5.0.1:
+
+	* dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
+	symbol in its raw form, we are processing an unlinked ".o" file.
+	See if the target environment has assigned it an address, using
+	target_lookup_symbol (VxWorks does), and enter it into the symtab
+	that way.
+
+	* tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID):  Override usual
+	68k versions for a simpler version that assumes zero FP at bottom.
+	Fixes bug of truncated stack reports.
+
+	* target.h (target_lookup_symbol):  Define this routine's args
+	and result, finally.
+
+	* target.c (nosymbol):  Default routine for target_lookup_symbol.
+	(target_default):  Default lookup_symbol and call_function too.
+	(files_info):  Only print has_all_memory warning if a non-dummy
+	target follows.
+
+	* remote-vx.c (vx_read_register, vx_convert_to_virtual,
+	vx_convert_from_virtual): If target does not have floating point,
+	zero register "values", and avoid doing cross-net conversions.
+	(vx_lookup_symbol):  Rename net_lookup_symbol, add to vectors.
+	(vx_open):  Rearrange code that attaches to target and reads
+	symbols for all loaded modules, to work if some of the modules
+	are not accessible.  Add symbol_stub() and add_symbol_stub()
+	as callbacks from catch_errors().  Allow connect attempt to be
+	interrupted painlessly with ^C (FIXME, there are still some bugs
+	if the interrupt happens during symbol reading.).  Print
+	final message with puts_filtered, since symbol messages are
+	now filtered too.
+
+	Misc cleanup:
+
+	* main.c (catch_errors):  Only print errstring if non-null.
+	(command_loop):  Avoid an ioctl per command to test ISATTY.
+
+	* remote-vx.c (net_load):  make static; avoid sophomoric msg.
+	(vx_xfer_memory):  Return correct result!
+	(vx_files_info):  Indicate whether target has float or not.
+	(vx_lookup_symbol):  Complain, not error, if target gone.
+	(vx_open):  Print "Connected" msg before disabling immediate-quit.
+	[FIXME:  lookup_symbol and vx_open changes need testing.]
+
+	target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
+	tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
+	contributor lines and update copyrights to 1991.
+
+	Changes from an attempted H-PUX host port:
+
+	* infptrace.c (PT_ATTACH, PT_DETACH):  Handle HP/UX, which 
+	defines PT_ATTACH and PT_DETACH but not PT_KILL.
+	* remote-eb.c (eb_open):  Misplaced endif kills sysv H/PUX.
+	* remote-vx.c: include <sys/time.h> for HPUX.
+	* hp300hpux-xdep.c (fetch_core_registers):  Rewrite old
+	"core_file_command" routine to BFD regime.  May not work yet.
+
+	Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
+
+	* xgdb.c: Replace X10 version with some VJ version.
+	(FIXME:  Its copyright assignment is not on record.)
+	* xgdb.c:  Update include files to X11R4 (Xaw crud).
+	(xgdb_display_source, create_text_widget): fix call to
+	get_filename_and_charpos.  Rewack source window stuff for X11R4
+	(gleaned from include files, and "nm's" of binary libraries, since
+	I had no doc available).
+	(append_selection, append_selection_word): Disable with FIXME
+	since R4 changed interface here.
+	(create_buttons):  Add back the old set of buttons.
+	(xgdb_create_window):  Fix call to XtInitialize (&argc not argc).
+
+	* Makefile.dist (xgdb, xgdb-init.c):  Update for X11R4 on Suns.
+	Roll VERSION to 3.94 (not yet final though).
+
+Sat Feb  9 09:46:25 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	* obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
+	obstack_int_grow, obstack_int_grow_fast):  Eliminate
+	cast on left of assignment, which gives MIPS cc fits and is
+	not Standard C.
+
+	* sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
+	F_ALIAS.  Use printf, not fprintf, when not passing a file
+	pointer...
+	(compare_opcodes): Check that identical instructions have
+	identical opcodes, complain otherwise.
+
+	* sparc-opcode.h (st %fsr):  Fix opcode "lose" mask.  This
+	was reported by Roland McGrath.
+	(unimp): Only match if exactly zero instruction.  (Roland)
+	(branches and traps):  Generate all variations of these
+	instructions with macros, based on a single call that defines
+	each condition name and its binary representation.
+	(set):  Turn on alias bit, to avoid test in sparc-pinsn.c.
+
+	* valprint.c (val_print_fields):  Take, and use, format parameter.
+	This means that "p/x struct" again prints the elements in the
+	desired format.  Changed callers.
+
+	* stack.c (frame_info):  Use filtered output, and indicate wrap
+	points.  Remove kludgy formatting designed to avoid line wrap.
+
+	* utils.c (wrap_here):  If the line is already full (because
+	we had printed a long indent or long wrapped string), do an
+	immediate newline-and-indent.
+
+	* m68k-pinsn.c (print_insn_arg): Bugfix from
+	ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
+	instruction is incorrectly disassembled as bkpt #8.
+
+	* dbxread.c (end_psymtab): Bugfix from Peter Schauer
+	<pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
+	breakpoint in a *.y file gdb will say Reading in symbols for *.y...
+	and then will dump core (sometimes). I traced it back to an
+	uninitialized symfile_name in psymtab_to_symtab.
+	(const_vol_complaint):  Add quotes to message.
+	(define_symbol):  Only believe line number if gcc_compiled.
+	Avoid allocating symbol if we will not return it.
+
+	Add target strata support so that newly established targets go
+	into their right place in the target stack (e.g. a new exec file
+	doesn't wipe out the ability to access the running process).
+
+	* target.h, core.c, exec.c, inftarg.c, remote-eb.c,
+	remote-nindy.c, remote-vx.c, remote.c, target.c:  Add to_stratum
+	and initialize it properly in all the targets.
+
+	* target.h:  Document strata.  Change return type of push_target.
+
+	* target.c (nomemory):  new function for dummy memory access.
+	(tcomplain):  Rename complain, now also used in symfile.c.
+	(push_target):  Push targets within strata.  New return value shows
+	whether new target is on top of stack or not.  Always keep dummy
+	target on stack.
+	(target_files_info):  Ignore dummy target.
+
+	* core.c (core_open):  Warn user, and skip accessing file, if the
+	core target is not the topmost target in the stack.
+	* remote-nindy.c (nindy_create_inferior):  Avoid unpush_target, now
+	already handled.
+
+	* remote-vx.c:  Remove vx_prepare_to_store from vxworks memory
+	target_ops, it doesn't belong there since we have no regs there.
+	Change name of target from machine => memory to clarify.
+
+Thu Feb  7 16:32:09 1991  John Gilmore  (gnu at spiff.cygnus.com)
+
+	* Freeze version 3.93 for release.
+
+	* Makefile.dist:  Handle vx-share and nindy-share subdirs
+	properly when building gdb.tar.Z.
+
+	* symtab.c:  lint; add no_symtab_msg to consolidate the messages
+	printed in various places, so I could change just one copy.
+
+	* dbxread.c, coffread.c:  Change references to bfd->iostream
+	to cast to FILE *, now that BFD avoids needing types defined
+	in other header files.
+
+Tue Feb  5 21:39:35 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	* command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
+	infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
+	sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
+	(actually gcc -Wall).
+
+	* dbxread.c:  Remove first_global_sym, last_global_sym, since
+	they are never referenced.
+
+	* defs.h (baud_rate):  Declare.
+	main.c: Define it, and add the -b option to set it.
+
+	* gdb-int.texinfo:  Add text on how to define a new host or target
+	architecture, prompted by Per Bothner's questions about MIPS
+	support.
+
+	* gdb.texinfo:  Document "complaints".  Change doc of -q since
+	gdb no longer prints the copyright and blurb if you specify a file
+	name to be debugged (just like Emacs).  Add doc for Nindy-specific
+	command line flags for specifying target serial port and such.
+	Update copyright to 1991.
+
+	* gdbcore.h:  Remove a large mass of now-useless crud, since BFD
+	has taken over for us the job of ripping up executable files.  The
+	crud caused Per Bothner's port to not compile.
+
+	* infrun.c (normal_stop):  Avoid printing "Program exited
+	normally" if we are in batch mode.  This allows a GDB which
+	executes a program on a target system, to behave like a Unix
+	command (input from stdin, output to stdout, no extraneous
+	output).
+
+	* main.c (main):  Allow additional machine-dependent command line
+	options to be specified with the ADDITIONAL_OPTIONS,
+	ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
+	ADDITIONAL_OPTION_HANDLER macros.  Also allow machine-dependent
+	processing to occur just before the main loop with
+	BEFORE_MAIN_LOOP_HOOK.  
+	(main):  If a "core file" argument is specified, and it is not a
+	core file, try it as a process ID to attach.  
+	(symbol_completion_function):  Attempt to cope with 
+	"show screen-" TAB, not very successfully.  This needs more work,
+	FIXME.
+	(batch_file):  New function, returns whether we are reading
+	commands from an interactive tty on stdin, or from somewhere else.
+	Called by normal_stop since it doesn't get from_tty passed down
+	to it like many commands do.
+
+	* remote-nindy.c:  Handle command line options for nindy
+	connection.
+	(nindy_before_main_loop):  Prompt user for tty name if they
+	don't specify it before getting to the interactive command loop.
+
+	* tm-i960.c:  Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
+	and -r command line options.  Also add hook before main loop
+	to make it easy to specify a tty.
+
+	* TODO:  More things to do, one done.
+
+Mon Feb  4 23:57:39 1991  John Gilmore and Mike Tiemann  (at cygint.cygnus.com)
+
+	* dbxread.c:  Make complaint() calls pass pointer, not struct.
+	Add complaints about badly formatted C++ type information
+	(const/volatile indicator, and parse errors resulting in
+	error_type).  Fix C++ virtual member fn comment.
+	(read_struct_type):  Avoid bumping pointer if we got a parse
+	error; this prevents our walking beyond the end of a string.
+	Terminate loop on null char as well as semicolon.
+	(process_one_symbol):  Fix the LBRAC fix so that it uses the
+	last previous SLINE, FUN, or SO record's PC address.  C++ debug
+	symbols did not have SLINE records in a useful order compared
+	to the LBRAC records.
+	(define_symbol):  Handle "catch" records.
+
+	* symtab.c (check_stub_type):  Added new complain
+	`stub_noname_complain' and added a consistency check to
+	keep the debugger from crashing when finishing from an
+	exception frame.  A real fix will be needed later.
+
+Sat Feb  2 10:43:05 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	* infcmd.c (attach_command):  Make global.
+
+	* Makefile.dist (REMOTE_OBS):  Make these compile by default,
+	but make them easy to comment out.  Perhaps later they should
+	be enabled by what CPU you configure for?  FIXME.
+	(VERSION):  Roll to 3.93.
+	(pinsn.o):  Remove rule for obsolete file.
+	(dbxread.o,coffread.o,mipsread.o):  Use ${srcdir} explicitly.
+
+	Run down a problem that manifested by printing the wrong function
+	name in stack traces of read_ofile_symtab.  Turned out that the 
+	problem was the SunOS 4.1.1 (and previous) C compiler outputs
+	the LBRAC symbol with an address in the *data* segment, which
+	blew our binary search through the blocks.
+
+	* dbxread.c: Use the complain() facility consistently to bitch
+	about problems in the symbol file we are reading.
+	(finish_block):  Add code to check the nesting of the blocks;
+	complain and Procrust them to fit if wrong.
+	(make_blockvector):  Check the order of the blocks, complain 
+	[but don't cope] if wrong.
+	(process_one_symbol):  ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
+	symbols to be sure their PC value is greater than the last SLINE
+	(line number) symbol we've seen, complaining and adopting the
+	SLINE PC value if wrong.
+
+	* symfile.h (struct complaint, complaint_root, complain, 
+	clear_complaints):  Add.
+	* symfile.c (complain, complaint_root, clear_complaints):  Add
+	facility to deal with non-fatal complaints and to regularize their
+	suppression.
+	(symbol_file_add):  Clear complaint counters to allow new complaints.
+	(initialize_symfile):  Add 'set complaints' and 'show complaints'.
+
+	* dbxread.c (dbx_symfile_read):  Remember the address and size
+	of the string table for the main symbol file, so we won't read it
+	more than once.
+	(dbx_psymtab_to_symtab):  Fix the check for main symbol file,
+	to avoid reading the string table yet again.  Lint.
+	(throughout):  Improve filtered output, including word wrap.
+	(read_range_type):  Improve Bothner's fix to handle other types too.
+
+	* utils.c:  Improve line wrap implementation.  Handle unlimited
+	width by making chars_per_line unsigned.
+	(puts_filtered):  New, easy, function.	
+
+	* defs.h (puts_filtered):  add.
+
+	* mipsread.c (compare_symbols, sort_symtab):  Remove these fns,
+	call the identical sort_symtab_syms() in symfile.c instead.
+
+	* expread.y:  Suggest the `file' command rather than `symbol-file'.
+
+	* command.h (enum var_types):  Add zinteger for seroable
+	unsigned integer.
+	* command.c (do_setshow_command):  Handle var_zinteger.  Restructure
+	nested if's into a switch.
+
+	* breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
+	we did not stop because of a breakpoint (it must have been for
+	some other reason, like a "stepi"), so don't print anything.
+
+	* symtab.c: Include <sys/types.h> all the time.  Now that BFD
+	doesn't include <sys/types.h>, old SunOS's require it for
+	<sys/stat.h>.
+
+Sat Feb  2 10:39:15 1991  Per Bothner  (bothner@cs.wisc.edu)
+
+	A test port of gdb-3.92.6 to the Sony NEWS.
+
+	* Makefile.dist
+	Don't normally link in remote- or vx stuff.
+	Some of it doesn't compile, and it wastes space for 99%	of the users.
+	Remove reference to no-longer-used HAVE_VPRINTF.
+	Fixed BFD_DEP typo to BFD_DIR.
+	* dbxread.c
+	Fix cast in arg to bfd_h_getlong.
+	Make char *prefix be const.
+	Fix how certain range types are mapped into builtin unsigned int types.
+	* infrun.c
+	Remove 2 #includes. They cause errors (on Sony, at least),
+	and aren't needed (they wern't in earlier versions).
+	* printcmd.c
+	print_address_symbolic should never demangle labels
+	(since it prints *assembler-level* labels).
+
+	       [This was superseded by the change to printcmd below.]
+
+	* utils.c
+	Add some "volatile" return types to avoid warnings.
+	If MISSING_VPRINTF add vprintf function and not just macro
+	(since vprintf is used in printcmd.c).
+	* valprint.c
+	Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
+	(The latter isn't grokked by some PCC-based compilers.)
+
+	     [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
+
+	Make chunk size of dont_print_obstack 32*4 instead of default 4096.
+	* nindy-share/coffstrip.c
+	Added some forward declarations (otherwise, gcc complains
+	about implicit extern redefined as static).
+
+Sun Jan 20 02:38:19 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	Changes inspired by Per Bothner:
+	* printcmd.c (print_address_symbolic):  Take additional parameter
+	specifying whether to demangle.
+	(print_address):  Pass in asm_demangle to control demangling.
+	(print_address_demangle):  New fn, takes explicit arg to control
+	demangling.
+	* utils.c:  Add new vars demangle and asm_demangle, and let them
+	be set and shown.
+	(fputs_demangled):  If !demangle, just print the argument.
+	(fprint_symbol):  If !demangle, just print raw symbol.
+	* valprint.c (val_print):  Call print_address_demangle rather than
+	print_address, to cause demangling to depend on the global
+	rather than assembler-level demangling setting.
+	* WHATS.NEW, gdb.texinfo:  Document.
+
+	* main.c (show_command):  Show all settings if no arg.
+	(initialize_main):  Make "info set" the same as naked "show".
+	* command.c (cmd_show_list):  Handle prefix commands in the
+	list, and print the name of the setting as well as its English
+	description and value.
+
+	Allow gdb functions to specify where a line should wrap if it
+	exceeds the size of a terminal line.  Use it to make the output
+	prettier.
+	* utils.c (set_screen_width_command):  New fn, mallocs a buffer
+	of the right size when screen width changes.
+	(set_screensize_command, screensize_info):  Remove #if 0'd fns.
+	(wrap_here):  New fn, indicates a point in the output where we
+	should wrap the line rather than just letting it overflow at a
+	random place.
+	(fputs_filtered):  Implement wrapping.
+	(n_spaces):  New fn, returns a pointer to N spaces.
+	(print_spaces_filtered):  Use n_spaces.
+	* defs.h (n_spaces):  Declare.
+	* stack.c (print_frame_info):  Wrap with 4-space indent after
+	fn name and before filename and line number.
+	* printcmd.c (print_frame_args):  Wrap with 4-space indent
+	before each argument name is printed.
+	* valprint.c (value_print):  Wrap with no indentation before
+	each repetition.
+	(val_print_fields):  Wrap with indentation relative to nesting
+	level before each field name.
+	(val_print):  Wrap with nesting indentation before array elements.
+	* command.c (do_setshow_command):  Avoid extra newlines,
+	wrap with 4-space indent around values printed, end with period.
+	* WHATS.NEW, gdb.texinfo, gdb-int.texinfo:  Document.
+
+	* breakpoint.c (breakpoint_1):  Implement addressprint for
+	"info breakpoints" display.  Change file name and line number
+	format to " at file:nnn" rather than " (file line nnn)".
+	* gdb.texinfo:  Document.
+
+
+Fri Jan 18 07:21:25 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	Frozen for gdb-3.92.6 release.
+
+	README, WHATS.NEW:  Update for 3.92.6 release.
+
+	tconfig/{altos, i386v, i386v32, m88k, umax}:  Eliminate
+	coffread.o from configs since it is now built by default.
+	tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
+	i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
+	pyramid, symmetry, vax, vxworks68}:  Eliminate dbxread.o
+	from configs since it is now built by default.
+
+	Makefile.dist: Update for release 3.92.6.  Handle files that
+	have been moved to ../include, ../getopt, or ../bfd.  Add
+	saber.suppress and tests directory.  Add config.status to
+	the release (it will say "none").
+
+	coredep.c:  Minor formatting fixes.
+
+	These changes were made in early December but only checked in now:
+	* nindy-share/Onindy.c, nindy-share/coffstrip.c,
+	nindy-share/nindy.c:  lint
+	* nindy-share/nindy.c (ninStopWhy):  Don't byteswap the 
+	register values coming back from the target; we store values
+	in target byte order everywhere.
+
+Wed Jan 16 19:01:37 1991  John Gilmore  (gnu at cygint.cygnus.com)
+
+	* am29k-opcode.h, am29k-pinsn.c:  Add 29050 opcodes.
+
+	* valprint.c (cplus_val_print, val_print_fields):  New functions,
+	which print C++ objects.  They conspire to avoid printing a
+	virtual base class more than once, following all the twists and
+	turns of C++ virtual base rules.
+	(val_print):  Call the above rather than do it by hand.
+
+	* symfile.c (symbol_file_add):  Only reset symfile_mtime for main
+	symbol file, not for added files like shared libs.  This really
+	needs to be generalized to a timestamp per file.
+
+	* core.c (cleanup_core):  Avoid coredump if no core file.
+	
+	* config.gdb:  Accept -host or -target in place of +host or
+	+target.
+
+	* coffread.c (find_linenos):  Avoid desupported BFD interface
+	to line numbers.  We still read them manually rather than using
+	BFD's "generic" features.
+
+	* gdbrc.tex, threecol.tex:  Add GDB reference card and its
+	formatting code.
+	Makefile.dist:  Add refcard to OTHERS list for creating tar files.
+
+	* Makefile.dist:  Eliminate use of $< in explicit targets.
+
+	* readline/Makefile:  Use $< rather than $*.c, which does not
+	include the VPATH in GNU Make.
+
+	* tconfig/i960-bout, tconfig/i960-coff:  These are identical
+	copies of tconfig/i960, added for global configuration
+	compatability.  All i960 versions can read both coff and b.out.
+
+	* tm-88k.h:  Fix multiline macro that lacked \'s.  Remove
+	COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
+	automaticaly.
+
+	* TODO:  Think of more things to do.
+
+Wed Jan  2 19:09:29 1991  John Gilmore  (gnu at spiff.cygnus.com)
+
+	tconfig/{am29k,i960,sun2*,sun3*,sun4*}:  Eliminate config
+	of sdb versus dbx debug symbols.  Add kludge for 68881 80-bit to
+	64-bit float conversion.
+
+	tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3:  Make
+	equivalent to sun?os4 so global config works.
+
+Wed Jan  2 18:20:51 1991  John Gilmore  (gnu at spiff.cygnus.com)
+
+	Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
+	
+	* main.c:  Only declare linesize once; declare pagesize not at
+	all, since it is never used.
+	(main):  Clear newly allocated line before it is used.
+
+Fri Dec 28 00:13:42 1990  John Gilmore  (gnu at cygint)
+
+	Further stabilization for the Intel 960.
+
+	* Makefile.dist: Parameterize the location of the "include"
+	and "bfd" directories, as well as "getopt".  Add symfile.c.
+	Link in both dbxread and coffread.  Fix up "make depend" to
+	rewack the locations of include, bfd, and getopt in its output.
+
+	* README:  Document moving include files, improve some of
+	the other doc.
+
+	* coffread.c:  Move common code out to symfile.c.  Change
+	symbol_file_command style interface to use new *_symfile_init
+	and *_symfile_read interface under BFD.  Use BFD internal
+	info to locate line table, symbols, etc.
+
+	* core.c (core_fetch_registers):  Rename to get_core_registers
+	to avoid confusion with fetch_core_registers.
+	(register_addr):  Move to coredep.c, which is already machine
+	dependent.  This leaves core.c pretty clean of dependencies.
+
+	* coredep.c (register_addr):  Accept this routine from core.c.
+
+	* dbxread.c: Move common code (with coffread.c, etc) into new
+	symfile.c.  Each psymtab now contains a pointer to the
+	format-dependent function that knows how to read it in.  Make
+	some things static.  
+	(dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
+	(process_one_symbol): Add code to complain about a "compiler bug
+	we muzzle here", if we actually see it.
+
+	* eval.c (evaluate_subexp):  Insert missing "break" statements
+	in code that determines whether a variable is an lvalue in
+	memory, register, or whatever.	I detected this via a compiler
+	bug in which it *almost* mashed out the whole switch statement.
+
+	* gdb-int.texinfo:  Add minor sections on configuring gdb for
+	release, and about the README file.
+
+	* infcmd.c (registers_info):  Fix formatting somewhat.  Still
+	not as pretty as before, but it handles byte swapping.
+
+	* remote-nindy.c: If data cache routines are interrupted while
+	waiting for the remote end, be sure that any uninitialized cache
+	blocks are on the free list, not on the valid list!
+
+	* symfile.h: Flesh out this header file with all the various
+	routines and variables that have been merged in from dbxread.c
+	coffread.c, and symtab.c to symfile.c.
+
+	* symfile.c: New file, containing code common to dbxread.c,
+	coffread.c, and some code from symtab.c.  All generic code for
+	reading symbol files should be in here now.
+	(unrecord_misc_function):  Remove unused function.
+
+	* symtab.h:  Remove file-reading things to symfile.h.
+
+	* symtab.c:  Remove file-reading things to symfile.c.
+
+	* tm-i960.h:  Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
+	to decode i960 fault types.
+
+	* target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
+	target.c: Change type of the "resume" function from int to void,
+	since its result was never used.
+
+Sat Dec 22 02:51:40 1990  John Gilmore  (gnu at cygint)
+
+	* main.c:  Replace "stupid" with "caution"; you now "set caution
+	on or off".
+
+	* printcmd.c (print_scalar_formatted):  Fix typo in 'g' format
+
+	* infcmd.c (do_registers_info):  Call val_print to deal with the
+	byte order of the registers being printed.  FIXME, this makes
+	the formatting of the output uglier.
+
+	* infcmd.c (wait_for_inferior):  If PRINT_RANDOM_SIGNAL is
+	defined, call it for signals the debugger doesn't itself use.
+	The i960 uses this for more detailed fault information.
+
+	* remote.c (remote_open):  If arg is null, print help rather than
+	dumping core.
+
+	* sparc-xdep.c (register_valid):  Avoid declaring size, since
+	various modules will think of various sizes depending on the
+	architecture of their tm-file.  FIXME, we need protection against
+	actually entering one of those modules, which would clobber
+	storage if not for the target architecture compiled into gdb.
+
+	* stack.c (up_command, down_command):  Always print the frame
+	you arrive at.
+	(up_silently_command, down_silently_command):  New commands
+	for use in scripts.
+
+	* i960-pinsn.c (reg), i960-tdep.c:  Lint.
+
+	* i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
+	more parameters than it used to.
+
+	* findvar.c (registers):  Increase slop to 256 bytes, which should
+	protect us against even most RISC machines with large register
+	sets.
+	(locate_var_value):  Move declaration inside related ifdef.
+
+	* remote-nindy.c ():  Use TIOCSETN rather than TIOCSETP
+	throughout, to avoid throwing away buffered input from the board.
+	(nindy_wait):  Supply_register takes addr_of_value, not value.
+	(i960_print_fault):  Renamed from i80960_fault.
+	(nindy_fetch_registers):  Avoid have_regs stuff, just get them.
+	(nindy_store_registers):  Avoid regs_changed stuff, just stuff
+	them.
+	(nindy_create_inferior):  Don't bother to write PC_REGNUM since
+	we can set the PC in the call to proceed().  Unpush nindy_ops
+	before pushing it on top, to avoid message to user.  Eliminate
+	commentary from Unix machines that just misleads here.
+	(reset_command):  Fix error message to suggest target command.
+	
+Wed Dec 19 11:03:56 1990  John Gilmore  (gnu at cygint)
+
+	Release 3.92.5 as frozen.
+
+	Stabilize the merged release...with help from lint, Saber C,
+	gcc -W, etc.
+
+	Everywhere:  Add include files needed to declare return types
+	of functions called.
+
+	* gdb.texinfo:  Roland Pesch is documenting gdb, glory be!
+
+	* breakpoint.h:  Add undeclared breakpoint functions, and some
+	functions for display handling since I couldn't think of a better
+	.h to put them in.
+
+	* breakpoint.c (insert_breakpoints):  Make code for disabling
+	shared library bkpts more likely to work.  It's used when we
+	rerun a program and stop before the shared library has been
+	mapped in.
+	(breakpoint_cond_eval, bpstat_stop_status):  Pass arg as int,
+	cast from pointer, so it squeezes through catch_errors.
+	(bpstat_stop_status):  Fix logic broken some time ago.  We now
+	always create a bpstat if the stop address matches a breakpoint,
+	even if we don't stop there -- just like the old code used to do
+	before I got my fingers into it (sigh).
+	(breakpoint_1):  Print "ignore count" after "stop only if"
+	condition, since that's how it actually works.
+	(mention):  Handle watchpoints as well as breakpoints.
+	(watch_command):  use set_raw_breakpoint and mention to do most 
+	of the work (and initialize all the fields!).  Only pass one
+	arg to parse_c_expression, since that's all it takes.
+
+	* command.c (not_just_help_class_command):  Rename arg to args
+	since we ignore "unused argument" warnings on vars named "args".
+	inflow.c (child_terminal_info):  ditto.
+	infptrace.c (kill_inferior):  ditto
+	main.c (catch_errors, version_info, quit_command, pwd_command,
+	source_command, dump_me_command, editing_info,
+	set_history_size_command, set_history, show_history,
+	set_verbose): ditto
+	stack.c (locals_info):  ditto
+	target.c (target_files_info):  ditto
+	valprint.c (set_input_radix, set_output_radix):  ditto
+
+	* core.c:  Remove old variables for handling core and exec file
+	sections (data_start, data_end, stack_start, stack_end,
+	reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
+	text_end, exec_data_start, exec_data_end, text_offset,
+	exec_data_offset, data_offset, stack_offset).  They're
+	superseded the more general build_section_table and
+	xfer_memory.
+	(get_exec_file):  Mention the `file' command.
+	(read_memory_check):  Rename to memory_error, and only call it
+	in the case of an actual error.
+	(read_memory, write_memory):  call memory_error.
+	(core_fetch_registers):  Register section name is ".reg".
+
+	coredep.c:  Remove a bunch of crud now that all this file does
+	is pull the registers out of a core file.
+	(fetch_core_registers):  Rewrite to actually work, I hope.
+
+	dbxread.c:  Use a.out.gnu.h, not system a.out, now.
+	Replace index() with strchr().  Remove all the pre-BFD macro
+	definitions for accessing the symbol file.
+	(struct dbx_symfile_info):  Encapsulate the information that
+	dbx_symfile_init needs to pass to dbx_symfile_read in this
+	struct.
+
+	(dbx_new_init, dbx_symfile_init, dbx_symfile_read,
+	dbx_symfile_discard): Rearrange symbol file reading to divide
+	the format-specific part from the format-independent part,
+	leaving the format-independent part such as file name expansion
+	and opening in symtab.c.  This replaces
+	partial_symbol_file_open and partial_symbol_file_read.
+	Symbol_file_read, add_file, add_file_target_command,
+	add_file_addr_command move to symtab.c.  Pass an explicit
+	"mainline" flag for when reading the main symbol table, rather
+	than relying on the offset address to be zero or nonzero.
+
+	(dbx_symfile_read): Don't allow void *'s to be printed as
+	typedefs.
+	(SWAP_SYMBOL):  Use bfd routines to byte-swap the symbols.
+	(ADD_PSYMBOL_TO_LIST):  Make the "function call rather than
+	macro" debug version really work.
+	(read_dbx_symtab):  Remove unref'd parameter inclink.
+	Avoid swapping N_SLINE symbols, for speed.
+	Merge N_TEXT!N_EXT case with the other external symbol
+	definitions' case. Add comments.
+	(start_psymtab):  Allocate the symfile name in the psymtab on
+	the psymbol_obstack, rather than using the caller's storage.
+	(end_psymtab): Only allocate a dependencies list if there are
+	more than zero.
+	(psymtab_to_symtab_2):  Use BFD when reopening file to read
+	its symbols for real.
+	(read_struct_type):  Add FIXME comments where it needs work
+	for C++ bogosity.
+	(read_huge_number):  Add FIXME about overflows.
+	(read_range_type):  Add FIXME about comparing a long to 1<<32.
+
+	* coffread.c:  Minor changes to move things closer to the new
+	regime with symtab.c and dbxread.c   Major work is still needed
+	here.
+
+	* exec.c (exec_file_command):  Remove old variables (see core.c
+	above).
+	(xfer_memory): If memory transfer is right at the end of a
+	section, don't lose.
+
+	* findvar.c (get_saved_register):  If value is in a real
+	register, LVAL is lval_register, not lval_memory.
+
+	frame.h:  Declare print_sel_frame and record_selected_frame.
+
+	gdb-int.texinfo:  New file, for GDB internals documentation.
+	Very simple, unformatted doc of cleanups is there for now.
+
+	gdbcore.h:  Remove obsolete variables that described a.out
+	section addresses and offsets.  (See core.c above.)
+	Declare fetch_core_registers and registers_fetched.
+
+	getopt.c:  Declare char *alloca(); even on SPARC.
+
+	infcmd.c (run_command):  Call target_kill rather than
+	kill_inferior. 
+	(step_command, next_command, stepi_command, nexti_command):
+	Declare from_tty parameter even though we don't use it.
+	(run_stack_dummy):  argument BUFFER is a char array, not
+	a pointer to REGISTER_TYPE.
+	(finish_command):  using_struct_return needed a value *, 
+	not a struct symbol *.
+
+	* infptrace.c (child_xfer_memory):  To avoid dependency on
+	where sections are in memory, try PT_WRITE_D and if that fails,
+	try PT_WRITE_I.  Most Unixes don't care which you use.
+
+	* infrun.c (step_resume_break_shadow):  Change to array to
+	match other breakpoint shadow storage.
+	(clear_proceed_status):  Pass address of bpstat to
+	bpstat_clear, not the bpstat itself.
+	(child_create_inferior):  FIXME comment about if the child
+	exits.
+	(start_inferior):  Remove old function.
+	(child_open):  Use target_kill rather than kill_inferior.
+	(wait_for_inferior):  Ditto.
+	(insert_step_breakpoint, remote_step_breakpoint):  Use
+	new step_resume_break_shadow.
+
+	* inftarg.c (child_wait):  If all child processes die,
+	pretend that the one being waited for exited with signal 42.
+
+	* main.c (command_line_input):  When scanning for comments,
+	don't coredump on unclosed quotes.
+	(quit_command):  Use target_kill rther than kill_inferior.
+	(_initialize_main):  Rename class_user from "user" to
+	"user-defined".
+
+	* printcmd.c (print_command_1):  Initialize "fmt" if no format
+	is specified by the user.
+	(print_frame_args):  Only add to args_printed if we are
+	actually fetching args from the stack (avoiding undefined
+	arg_size).
+	(_initialize_printcmd):  Remove bogus \{ from string.
+
+	* remote-eb.c (eb_open):  Avoid coredump on no argument.
+
+	* remote-nindy.c:  Bring out of Intel environment into new
+	target environment.  Remove all conditional compilation on
+	I80960.  Massive hacking throughout.
+	(nindy_xfer_inferior_memory):  New routine stolen from
+	infptrace.c.
+	(nindy_create_inferior):  New routine pieced together, probably
+	not quite working yet.
+	(nindy_ops):  New target_ops struct for nindy.
+
+	* remote-vx.c:	Use write_memory rather than target_write_memory
+	to get error checking.
+	(vx_add_file_command, vx_open): Use symbol_file_add rather than
+	add_file.
+	(vx_create_inferior):  Use target_terminal_ours...
+
+	* signame.c (_initialize_signame):  Always initialize, since
+	we need the table for things other than psignal.
+	
+	* solib.c (solib_add):  Use symbol_file_add, not add_file.
+	(solib_address):  Return boolean result rather than struct
+	pointer which nobody else knows the type of.
+
+	* sparc-tdep.c, valops.c:  Use write_memory rather than
+	target_write_memory, to get error checking.
+
+	* stack.c (locals_info, catch_info, args_info,
+	get_selected_block, frame_command, up_command): Use
+	target_has_stack, rather than have_inferior_p or
+	have_core_file_p.
+
+	* sun3-xdep.c (fetch_core_registers):  Rewrite for new BFD regime.
+
+	* symfile.h:  New file, defining the interface between the
+	generic and object-file-specific symbol reading code.
+
+	* symtab.c:  Move generic symbol-reading interface to symtab.c,
+	from dbxread.c, coffread.c, mipsread.c, etc.  Add symtab_fns
+	table to map BFD targets to symbol-reading modules in GDB.
+	Change index to strchr.
+	(lookup_struct_elt_type):  Use error() rather than hand-made
+	simulations thereof.
+	(lookup_partial_symbol):  Speedup slightly when length == 0.
+	(symbol_file_add):  New function.
+	(symbol_file_command):  Call it.
+	(symfile_open, symfile_init):  New function.
+	(add_file_target_command, add_file_addr_command): moved from
+	dbxread.c.
+
+	* target.c (target_command):  use target_kill.
+
+	* target.h (target_files_info):  Don't declare, never called
+	from outside.
+
+	* tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
+	files to determine stack end address.
+
+	* valarith.c (value_x_binop, value_x_unop): Change error message
+	to be more useful.  Pass proper argument to value_struct_elt.
+
+	* valops.c (value_assign):  FIXME comment that long long 
+	bitfields will break here.
+
+	* Makefile.dist:  Add symfile.h, remote-nindy.c, remote-eb.c.
+	Update `make saber_gdb' to work better.
+
+	* TODO:  A woman's work is never done.
+
+	* cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
+	main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
+	remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
+	sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
+	target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
+	valops.c, valprint.c, exec.c:  Lint.
+
+
+Wed Dec 12 23:44:15 1990  John Gilmore  (gnu at cygnus.com)
+
+	Continuing Intel 960 port merge of GDB.
+
+	* Makefile.dist:  Merge i960 "nindy-share" files.  Rename
+	malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
+	Don't ship gdb.dvi in tar file.  Link gdb with init.o, not init.c.
+	Wack over "make depend" so it handles files in subdirectories
+	vx-share, nindy-share, bfd, and in the current directory.
+
+	* blockframe.c (get_prev_frame_info):  Remove fatal error
+	if stack not defined.
+
+	* core.c (core_open, core_detach):  New functions that handle
+	the old "core-file" command as "target core" and "detach" instead.
+	(core_file_command):  Call them.
+	(core_xfer_memory):  Use common routine xfer_memory.
+
+	* dbxread.c:  Include a.out.gnu.h, not system a.out.h.
+	dbxread now uses bfd for everything but symbol reading itself.
+	BFD internals are used to drag out the relevant file offsets.
+	(partial_symbol_file_open):  Change args all around for BFD.
+
+	* symtab.c: Rename "value" to "val" everywhere, so we can
+	#include "value.h".
+	(symbol_file_command):  New command, moved from dbxread.c
+	and coffread.c.  It uses BFD to read the file, then vectors
+	based on its type, to dbx or coff symbol readers.
+	* symtab.h:  Extern a few vars for symbol_file_command.
+
+	* target.h:  Breakpoint takes a char * save area, not a char **.
+
+	* valprint.c (val_print):  When unpacking bitfields, offset
+	the address in gdb of the value, if it is declared with a shorter
+	type.  Remove the last "runtime kludge test" of host byte order.
+
+	* utils.c:  Remove old my_bfd_read routine.
+
+	* stack.c (frame_info):  Use target_has_stack.  Print program counter
+	register's actual name rather than "pc", since it's called the
+	"ip" (instruction pointer) on the i960 (sigh).
+
+	* target.c (target_command):  Add command for selecting a target
+	type and calling its open routine.  This is used for initiating
+	communication with a particular target, in a generic way.
+
+	* tm-i960.h:  Update for modern gdb.  Remove semicolons from
+	various macros.  Handle reading struct return convention, and
+	error-out attempts to return structs with the "return" command.
+	Be sure gdb doesn't think we know how to call functions in the
+	inferior.
+
+	* i960-tdep.c:  Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
+	to i960_xxx in lower case.
+	(arg_address):  Circumvent errors due to LOC_ARG_BLOCK
+	not being defined yet.
+
+	* remote.c (remote_open):  Call start_remote to initialize 
+	wait_for_inferior during open.
+	(remote_xfer_inferior_memory):  Return length written rather
+	than errno value.
+
+	* remote-vx.c (target_command -> vx_open):  Use new generic
+	target command.
+	* remote-eb.c, inftarg.c, exec.c: ditto.
+
+	* infrun.c:  Fix comments.
+	(attach_program -> child_open):  Use new generic target command.
+	(wait_for_inferior):  Clear saved register values before target_wait,
+	so target_wait can set some of them if convenient.
+
+	* infptrace.c (fetch_inferior_registers, store_inferior_registers):
+	Return success indicator, not void.
+	(child_xfer_memory):  Avoid fetching initial word if we'll
+	overwrite it anyway.
+
+	* infcmd.c (attach_command):  Use new generic target open routine.
+	(_initialize_infcmd):  Update doc on attach and detach commands.
+	(do_registers_info):  Merge in a byte-order problem as a FIXME
+	comment.
+
+	* findvar.c (find_saved_register):  Avoid problem in current frame.
+	(read_relative_register):  Ditto.
+	(write_register):  Convert byte order on the way out.
+
+	* exec.c (file_command):  Add.
+	(add_to_section_table, exec_command):  Use new bfd_map_over_sections.
+	(xfer_memory):  Common function between core_xfer_memory and
+	exec_xfer_memory.
+	(exec_xfer_memory):  Use it.
+
+	* pn-opcode.h:  Document that a "PN" is a Gould PowerNode.
+
+	* breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
+	valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
+	infcmd.c, i960-pinsn.c, eval.c, defs.h:  lint and gcc -Wall.
+
+Sun Dec  2 16:45:06 1990  John Gilmore  (gnu at cygnus.com)
+
+	Merge Intel 960 port of gdb, continuing...
+
+	* dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
+	symbol_file_command):  Pass from_tty arg to hush 'em up.
+
+	* coffread.c (symbol_file_command):  Avoid output if from_tty != 1.
+	Add magic numbers for 960 COFF format.
+
+Fri Nov 30 09:18:20 1990  John Gilmore  (gnu at cygnus.com)
+
+	Merge Intel 960 port of gdb, from Intel "1.2" release.
+
+	CHANGE_LOG entries from their port, which was based on
+	gdb+-2.8.0:
+
+    Thu Sep  6 11:02:22 PDT 1990
+	Remove temp file if download is interrupted.
+
+    Wed Aug  1 09:08:33 PDT 1990
+	Now uses binary protocol to talk to NINDY.
+	Old hex protocol (NINDY 2.13 and older) supported with -O switch.
+	Times out after 5 seconds when trying to talk to NINDY.
+
+    Tue May 29 12:54:49 PDT 1990
+	Added variable baud rate (-b switch).
+	Source code reorganization.
+
+    Thu Apr 26 11:09:55 PDT 1990
+	More cleanup of batch mode;  specifically, execute "-s", "-e", and
+	"-se" switches as soon as they are encountered on the invocation line.
+
+    Fri Apr 20 13:47:15 PDT 1990
+	Add -brk switch.
+
+    Thu Apr 19 09:54:28 PDT 1990
+	Add 'reset' command.
+
+    Wed Apr 18 09:48:07 PDT 1990
+	After opening remote tty, wait for 1 second to go by without input
+	from it before trying to talk to NINDY (fixes problems with the
+	Heurikon HK80/V960E).
+
+    Mon Apr  4 16:33:05 PDT 1990
+	Some output was not being suppressed in 'batch' mode.
+
+    Thu Mar 22 15:31:11 PST 1990
+	Ask user if old symbol table should be deleted when new file is
+	downloaded.
+
+	Allow user to run a program downloaded before gdb960 was brought up.
+
+	Correct "exec-file" help message for i80960 context.
+
+	Correct bug in calculating user space address:  could occasionally
+	corrupt user program.
+
+	Make sure to zero low-order bits in rip's because of bug in 960CA
+	A-step part:  could cause operation faults when "next"ing across
+	a function call.
+
+	Correct bug that made it impossible to get source line numbers for
+	code loaded at addresses higher than 0x7fffffff.
+
+    Wed Jan 10 12:43:22 PST 1990
+	Open remote tty for exclusive use.
+
+    Fri Jan  5 12:14:42 PST 1990
+	Correct disassembly (CA manual was right after all):
+	opcode for sysctl is 0x659
+
+    Mon Oct 23 12:03:04 PDT 1989
+	Use G960BASE and G960BIN environment variables to find 'sx' utility.
+
+    Mon Oct 16 14:15:09 PDT 1989
+	"sfr0"-"sfr31" should have been named "sf0"-"sf31"
+
+    Mon Oct  2 15:56:31 PDT 1989
+
+	Added 960CA disassembly support.
+
+	To simplify maintenance:
+		- eliminated use of symblic links on pinsn.c: use i960-pinsn.c
+			directly instead.
+		- eliminated opcode.h: incorporates tables into i960-pinsn.c
+		- moved 960-specific routines from i960-pinsn.c to i960-md.c
+		- made disassembly interface identical to that in gdmp960.
+
+
+
+Wed Nov 28 21:32:48 1990  John Gilmore  (gnu at cygint)
+
+	* target.h: Allow targets to stack.  Add target_has_memory,
+	_registers, etc.  Restructure memory access and "info files"
+	to walk the target stack.
+	* exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
+	target.c:  Change tables to match target.h.
+	* 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.
+	* printcmd.c (print_scalar_formatted):  Print formatted hex
+	numbers in varying column widths.
+	* valprint.c (val_print):  Use output_format to print scalar ints.
+	(set_input_radix, set_output_radix, set_radix):  Create.
+	(set_output_radix):  Set output_format from output_radix.
+	(_initialize_valprint):  add `set radix' but leave the others off.
+	
+	* main.c (execute_command): Let stupid questions be turned off.
+	(_initialize_main): Handle "set stupidity", etc.
+
+	* main.c, inflow.c, inferior.h, frame.h, command.c, defs.h, 
+	sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c:  Lint.
+
+Tue Oct  2 11:20:02 1990  John Gilmore  (gnu at cygint)
+
+	* TODO, Makefile.dist, ChangeLog:  Freeze for 3.91.8 release.
+	bfd stuff is still screwed up, but with some manual work, it
+	compiles.
+
+	* breakpoint.c (bpstat_do_actions):  Start over if a command
+	proceeds the inferior, since the inferior will have stopped and
+	will need to have its new stop-actions taken care of.
+
+	* dbxread.c (read_struct_type):  Expression gives Sun3 4.0.3
+	compiler fits, simplify it.
+
+	* gdb.texinfo (directory command): Doc new dir command.
+	source.c (directory_command):  "dir" now puts things on the front
+	of the path, moves dups up front, and handles multiple names
+	on the command line, inserting each one in order.  It also
+	blows away cached line and full_filename info.
+
+	* stack.c (backtrace_command):  Skip "more stack frames follow"
+	unless interactive.
+
+	* Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
+	xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h, 
+	xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
+	The only odd one was Gould NP1, which had defined vprintf to
+	"printf"!!!
+
+	* Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
+	printcmd.c (print_command_1): Pass 'inspect' flag down as a global
+	variable, inspect_it.
+	valprint.c (print_string, val_print): Use the global inspect_it
+	to indicate whether to print in Epoch style or normal style.	
+
+Mon Oct  1 23:55:26 1990  John Gilmore  (gnu at cygint)
+
+	* printcmd.c (call_command):  add an alias for the "print" command
+	which runs expressions and doesn't print the result if void.
+	(print_command_1): implement it.
+
+	* command.c: Remove #if 0'd code.  Initialize all the fields
+	in add_cmd ().  Rename do_nothing_command to
+	not_just_help_class_command, and make it externally visible.
+	command.h: add user_commands to struct.
+	* main.c (define_command):  Don't overload c->function with a char
+	string as well as a function pointer.
+
+	* eval.c (evaluate_subexp):  Reinstall tiemann changes to
+	calling convention of value_struct_elt () that got dropped in
+	merge.
+
+	* tm-sparc.h (FRAME_FIND_SAVED_REGS):  move to sparc-xdep.c.
+	sparc-tdep.c (sparc_frame_find_saved_regs):  ditto.
+
+	* tm-sparc.h (POP_FRAME): replace some constants with defines.
+
+	* sparc-xdep.c (store_inferior_registers):  defer stores to regs
+	until a good time (e.g. when we are about to run the child),
+	saving ptrace calls.
+    	* infrun.c (proceed):  handle DO_DEFERRED_STORES.
+	* tm-sparc.h: define DO_DEFERRED_STORES.
+
+	* sparc-xdep.c (store_inferior_registers): when storing float
+	registers, don't store stack regs too.  When storing the SP,
+	however, DO store the stack regs too.  This fixes a bug in which
+	the dummy frame is not recognized when a call_function finishes,
+	because its frame pointer (in the stack regs) was never
+	initialized.
+	(read_inferior_registers):  Mark WIM and TBR and FPS and CPS valid
+	even though we don't know how to read them from an inferior.
+	valops.c (call_function):  Comment about storing SP.
+
+	* infrun.c (save_inferior_status): Save away the original bpstat
+	chain so it can be restored later.  Install the copied version for
+	use by whoever saved the status.  It will be blow away by
+	restore_inferior_status, and the original chain restored.  This is
+	important for people who have pointers into the original.
+
+	* breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
+	findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
+	main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
+
+
+Fri Sep 28 20:32:46 1990  John Gilmore  (gnu at cygnus.com)
+
+	* Makefile.dist: Roll version to 3.91.8.  Add bfd.h and bfdconfig.h
+	temporarily to the makefile.  Add am29k-opcode.h and WHATS.NEW.
+	Add stuff.c and kdb-start.c to the OTHERS list for tar files.
+
+Fri Sep 28 19:12:12 1990  John Gilmore  (gnu at cygint)
+
+	* Merge Mike Tiemann's multiple inheritance changes from Sun.
+	Store the baseclasses in a type struct starting from array element
+	0 rather than from the unusual array element 1.
+
+	dbxread.c: the above.
+	(virtual_context): Add
+	Read new debug information about which virtual function table
+	a virtual function is from, and store it in fn_field.fcontext.
+	
+	symtab.h: Add fcontextt.  Fix baseclass indices.  Typo in
+	TYPE_FN_FIELD_STATIC_P.
+
+	symtab.c: the above.
+	valops.c: the above.  Handle pointer casts of object *'s.
+	(search_struct_method): Add.
+	(value_struct_elt): First arg is now a pointer to a value, and is
+	modified on return.
+
+	valprint.c: the above.
+	values.c (value_virtual_fn_field): Add type arg.  Handle
+	offsetting to the proper object when calling virtual fns.
+	The above.
+	(baseclass_addr): Add valuep arg.
+
+	* README:  Document the current state of BFD config (missing).
+	* TODO, ChangeLog, Makefile.dist: Roll version.
+	* WHATS.NEW: Add summary of changes since 3.5.
+
+Thu Sep 27 16:23:12 1990  John Gilmore  (gnu at cygint)
+
+	* dbxread.c (read_struct_type): Clear bit vectors whenever
+	we allocate one.
+	symtab.c (B_CLRALL): define.
+
+	* tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
+	using == rather than =.  Huh...  This fixes the dreaded problem
+	wherein builtin_type_int becomes TYPE_CODE_FLT.
+
+	* core.c (info_files): Show the inferior pid.
+
+	* config.gdb: Avoid putting "dir" command into .gdbinit.  GDB
+	already knows how to look in the source directory.
+
+	* Remove psymtab hair from many places.  Remove duplicated code
+	for searching symbol tables.  Hide psymtabs from most places.
+	Make it fast to get from a psymtab to its symtab.
+
+	blockframe.c (blockvector_for_pc): Remove psymtab hair.
+	coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
+	mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
+	dbxread.c: export psymtab_to_symtab, make it work if called N times.
+	(psymtab_to_symtab): Rename to psymtab_to_symtab2.  Initialize
+	new symtab completely.  New psymtabs get symtab pointer
+	initialized to zero.  Remove MI warning printf.  
+	symtab.h: Comments.  Add psymtab to symtab pointer.
+	(PSYMTAB_TO_SYMTAB): New macro.
+	symtab.c: use PSYMTAB_TO_SYMTAB.  Add psymtab_to_symtab and export it.
+	source.c: use PSYMTAB_TO_SYMTAB.  Remove symtab version and
+	compilation fields.
+	stack.c (backtrace_command): Avoid pre-pass to read symbols, if
+	verbose is not set.
+	(print_frame_info): Avoid special-casing symbols that have not yet
+	been read in.
+
+	* source.c (open_source_file): Quick path if we have already
+	located the source file by its full name.
+
+	* symtab.c (lookup_symbol): Use find_pc_symtab rather than
+	find_pc_psymtab.  When a name is found in the misc function
+	vector, search the symbol table for its mangled name, not the
+	name that the user typed.
+
+	* bfd.h: Fix missing comment terminators, make #endifs match.
+
+	* valarith.c (value_less): Handle unsigned int comparisons.
+	Add FIXME about pointer compares, which assume host and target
+	pointers are the same.
+
+	* command.c (do_nothing_command): lint
+	dbxread.c: lint.  Remove sort_syms.  Document C++ visibility info,
+	fix comments on debug symbol format for visibility.  Actually set
+	visibility of symbols.
+	main.c (echo_command): lint; use <readline/history.h>.
+	tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
+	obstack.h (_obstack_blank): Rearrange pointer math to avoid
+	pointing past end of allocated memory; saber complains.
+	obstack.h: Declare the external functions that we use.
+	valarith.h: use <string.h>
+	solib.c (solib_add): lint.
+
+Fri Sep 21 17:05:19 1990  John Gilmore  (gnu at cygint)
+
+	* main.c (initialize_main):  Default info_verbose to off, now that
+	symbol reading is fast.
+	(quit_command):  Avoid clobbering exec_bfd while quitting.
+
+	* Initial BFD (binary file diddling library) merger:
+	coffread.c: Change AOUTHDR to struct exe_hdr.
+	dbxread.c: ditto.
+	core.c: initialize initialized data at compile time.
+	(core_file_command):  Move from coredep.c, convert to bfd.
+	(xfer_core_file): Convert to bfd.
+	exec.c (exec_file_command): use bfd routines.
+	gdbcore.h: BFD.
+	mips-tdep.c: Remove exec_file_command and friends.
+	source.c: bfd.
+	
+	* coredep.c: (fetch_core_registers) Convert core_file_command to
+	fetch_core_registers.
+	mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
+	
+	* utils.c: (error): Bogus crap, FIXME, to print bfd errors.
+	(my_bfd_read): More bogosity, which I don't think we call.
+	(program_name): Remove this atrocity asap!
+
+Wed Sep 19 13:36:41 1990  John Gilmore  (gnu at cygint)
+
+	* From Per Bothner:
+	values.c: allocate_repeat_value was not clearing the
+	optimized_out field.
+	(value_static_field): minor stylistic fix (wrong macro was used).
+	valops.c (value_struct_elt_for_address): didn't work for C++
+	static fields.
+
+	* signame.c (_initialize_signame):  Initialize signal names once.
+
+	* breakpoint.h, command.c, copying.awk, defs.h, environ.c,
+	exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
+	symtab.h, tm-29k.h, valprint.c, value.h, values.c:  Lint.
+
+	* remote-eb.c:  Support user-settable baud rates on the serial port.
+
+	* tm-sun3.h (PREPARE_TO_STORE): fix typo.
+
+Fri Sep 14 13:28:29 1990  John Gilmore  (gnu at cygint)
+
+	* tconfig/sun3os4: Remove warning about native assembler,
+	since it also occurs in the xconfig file.
+
+	* findvar.c (registers): Allocate some slop after `registers'
+	to prevent stray accesses from trashing the next variable.
+
+	* tm-68k.h (REGISTER_BYTES):  Allocate the right number of bytes
+	on the sun-3, by changing the #ifdef from `sun3' (which is not
+	defined by cc) to `sun'.  Symptom was trashed builtin_type_XXX
+	vars, which happened to follow `registers' in the executable.
+
+	* readline/history.c (history_search): Heed gcc-2's advice
+	and parenthesize && inside ||).
+
+	* am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
+	tm-29k.c:  Insert FSF copyright headers.
+
+	* remote-eb.c:  Better comments.
+
+	* Makefile.dist:  Update to 3.91.6.
+	* TODO: note PREPARE_TO_STORE problem.
+
+Thu Sep 13 09:52:33 1990  Jim Kingdon  (kingdon at cygint)
+
+	* stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
+
+	* remote.c:  Wrap the whole file in #if !defined (SPECIAL_REMOTE).
+
+	* infrun.c (wait_for_inferior, at end): Don't set up
+	prev_* if the inferior no longer exists.
+
+	* inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
+	CANNOT_EXECUTE_STACK.
+	valops.c (call_function): Use it.
+
+	* tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
+
+	* inferior.h (PC_IN_CALL_DUMMY): New macro.
+	infrun.c (wait_for_inferior, 2 places): Use it.
+
+	* values.c (value_being_returned): Only use
+	EXTRACT_STRUCT_VALUE_ADDRESS if defined.
+
+	* Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
+	right thing for remote-eb.c.  
+
+	* sun3-xdep.c:  Remove extraneous call to remote_store_registers.
+	* sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c:  Ditto.
+
+	* blockframe.c:  Put get_frame_saved_regs inside #if !defined
+	(FRAME_FIND_SAVED_REGS).
+
+	* findvar.c ({fetch,store}_registers): Check for
+	REMOTE_{FETCH_STORE}_REGISTER macro.
+
+	* findvar.c (get_saved_register): Add argument lval and
+	change meaning of argument addr.
+	findvar.c:  Change calls to get_saved_register to reflect
+	new calling convention.
+	valops.c (value_assign): Use get_saved_register instead of
+	find_saved_register.
+
+Sun Sep  2 12:40:20 1990  Jim Kingdon  (kingdon at cygint.cygnus.com)
+
+	* coffread.c (read_one_sym): Make temp_aux an AUXENT, not
+	an (uninitialized) pointer to one.  Use "&" when passing it
+	to fread.
+
+Fri Aug 31 22:57:54 1990  Jim Kingdon  (kingdon at cygint.cygnus.com)
+
+	* coffread.c (getfilename): Use DGUX x_offset and x_name if
+	defined.
+
+	* coffread.c (symbol_file_command): Put semicolon after
+	"int from_tty".
+	Put safe_to_init_tdesc_context in #if defined (TDESC).
+	Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
+	coffread.c: #include <sys/stat.h>.
+	(read_coff_symtab): Typo: in_source_files -> in_source_file.
+	Add missing ')' in check for "lc%" and friends.  Remove
+	extraneous '}'.
+	Declare read_one_sym() at top of file.
+	(read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
+	MC68WRMAGIC can have the same value without causing a duplicate
+	case.
+
+Thu Sep 13 15:55:36 1990  John Gilmore  (gnu at cygint)
+
+	* Allow a Makefile to be built without building the
+	tm and xm file links that screw up builds in subdirectories.
+	This is done with `config.gdb none', then you can do things
+	like `make gdb.tar.Z'.
+	* tconfig/none: Config file for no target system
+	* xconfig/none: Config file for no host system
+	* config.gdb: If no TM or XM files are called out by the
+	host or target file, don't make links for them.
+
+	* cplus-dem.c: Add documentation.
+
+	* dbxread.c (read_ofile_symtab): Turn a fatal error into a
+	simple error, so the user's gdb doesn't crash due to some object
+	file problem (e.g. somebody is rebuilding the file out from under
+	gdb).
+
+	* printcmd.c (print_address_symbolic): demangle the symbol.
+
+	* Makefile.dist (OTHERS): Remove tdesc-lib because it has 
+	Motorola copyrights in it.  Make "make gdb.tar.Z" work.
+	(alldeps.mak): sort and uniq all results from this; duplicates
+	hose gdb.tar.Z link building.  Remove RCS files from
+	tconfig and xconfig.  Add config files for sun386.  Add
+	a few odd files to OTHERS and HFILES.
+
+Mon Sep 10 21:20:24 1990  John Gilmore  (gnu at cygint)
+
+	* Makefile.dist: Pull solib.c to tconfig/sun?os4.
+	Roll version number to 3.91.5.  Make lint work in bindir.
+
+	* README:  Document cross-debugging and new file structure.
+
+	* blockframe.c: Lint.  Include "value.h" to declare read_register.
+	(find_pc_partial_function): remove duplicate line.
+
+	* command.h: Lint.  Declare error_no_arg and dont_repeat.
+
+	* tm-news.h: Remove inadvertently duplicated stuff.
+
+	* mipsread.c: Remove cache_pc_function stuff, now done cleanly.
+	Clean up usage of misc_function_type.  Declare some CORE_ADDRs.
+
+	* config.gdb: Allow `config.gdb host target' form.  Clean
+	up previous change that printed bogus messages when you just said
+	`config.gdb'.
+
+	* core.c: #include "command.h" for lint.
+	* dbxread.c: lint
+	* eval.c: lint
+	* main.c: Remove some casts of enums.  Lint.
+	* source.c: lint
+	* symtab.c: lint
+	* symtab.h: lint
+	* expread.y: lint
+	* valarith.c: lint
+
+	* printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
+	
+	* sparc-tdep.c (isannulled): Take instruction as parameter, don't
+	read it from memory.  This will allow us to save ptrace calls
+	eventually.   Changed caller single_step too.
+
+	* sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
+	that we aren't going to use, saving many ptrace calls, especially
+	when watchpointing or single stepping.  Use some #define's for
+	constants.
+	(store_inferior_registers): Ditto.
+	(core_file_command): Use some #define's for constants.
+
+	* tm-sparc.h: Add #define's for some register numbers, so we
+	can eliminate the use of random constants in sparc-xdep.c.
+
+	* stack.c (frame_command, print_frame_info, up_command,
+	down_command) Remove frame_changed, since it
+	causes a bug and doesn't seem to do anything useful.  In some
+	places it was used as a flag, in others as a stack level (?).
+
+	* utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
+	default is to use the portable (vprintf) version rather than the
+	kludge version.
+	* xm-news.h (MISSING_VPRINTF): Add.
+
+	* valprint.c (val_print): Demangle fancy vtbl printouts.  Lint.
+
+Sat Sep  8 00:24:12 1990  John Gilmore  (gnu at cygint)
+
+	* Remove stuff that forces -Bstatic linking of gdb, and warnings
+	about linking debugged programs -Bstatic in the sun?os4 config
+	files in tconfig and xconfig subdirectories.
+
+	* main.c (main):  Remove unreached exit(0) now that we exit
+	via quit_command().
+
+	* Create TODO file for online bug list.  There are too many
+	"little" bugs to keep track of on paper.
+
+	* Change Projects file to refer to bug-gdb@cygnus.com
+	rather than kingdon@ai.
+
+Fri Sep  7 23:35:15 1990  John Gilmore  (gnu at cygint)
+
+	* Makefile.dist (VERSION): 3.91.4 now.
+
+	* symtab.c (init_misc_bunches): Rename from init_misc_functions.
+	(condense_misc_bunches): Add sanity check that misc_count is
+	the same as the number of symbols in the bunch.
+	
+	* coffread.c: rename init_misc_bunches.  Pass an argument 
+	to condense_misc_bunches (a zero).
+
+	* dbxread.c (partial_symbol_file_read): Call init_misc_bunches
+	every time we are called; don't rely on our caller to do it.
+	(add_file): Remove call to init_misc_bunches.
+
+	* mipsread.c: Only warn, don't error, if unknown symbol types.
+	This keeps an old gdb from falling on its face if it sees newly
+	extended symbol info.  Rename init_misc_bunches.
+
+Fri Sep  7 22:58:15 1990  John Gilmore  (gnu at cygint)
+
+	* Merge in changes from Per Bothner for DECstations and other
+	MIPS stuff.  The rest is Bothner speaking:
+
+	The next message is a merger of Alessando Forin's mips port with
+	mine.  I've tried to use my good if biased judgment to get
+	the best of both. It *does* need testing.
+
+	Some of the changes are general, *not* mips-specific.
+
+	param.h:
+	Didn't believe in little-endian bit order.
+	There are still inconsistencies about whether flags
+	like BITS_BIG_ENDIAN are integer (#if ...) or
+	boolean (#ifdef ...). I tried to paper over them.
+
+	dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
+	Moved some misc_function code that was common to
+	{dbx,coff,mips}read.c to symtab.c.
+	In the process, I think I cleaned things up a bit.
+	At the same time, moved obsavestring and obconcat to symtab.c.
+
+	dbxread.c:
+	Removed obsolete condense_addl_misc_bunches (use
+	condense_misc_bunches(1) instead).
+
+	exec.c:
+	Needed to include <sys/dir>, at least on DECstations.
+
+	valops.c, mips-tdep.c, tm-mips.h:
+	Added PUSH_ARGUMENTS macro to support funny argument-pushing
+	conventions (when STACK_ALIGN is insufficient).
+	Needed on mips, where doubles need 8-byte alignment,
+	but ints only need 4.
+
+	mips-opcode.h:
+	Removed cruft that was not being used.
+	Merged in many fixes (most from Frank Yellin, fy@lucid.com).
+
+	mips-pinsn.c:
+	Print $ before register-names (I think that makes things a little
+	more consistent).
+	Never print two instructions, even if one delays.
+	Removed hex-disassemble set_cmd.  (This is not mips-specific,
+	so I think the argument is whether it is generally worthwhile or not.
+	I'm inclined to think not, given how easy it is to
+	convert between radixes in gdb.)
+
+	mipsread.c:
+	This is basically Alessando's code.
+	It doesn't use obstacks; I changed it to use obstacks
+	in a few minor places where using malloc causes a
+	memory leak. (Probably, more places could/should be changed.)
+	I added record_misc_function where it was missing.
+	In symbol_file_command and add_file_command, I tried
+	to make the code consistent with more recent versions.
+	Minor sylistic changes in parse_procedure.
+	Make a .gdbinfo. psuedo-symbol point back to the real
+	procedure symbol (using the isym field).
+
+	mips-tdep.c:
+	This is basically from my port, but with a lot of details
+	and a number of routines merged in from Alessando's version.
+	I basically used my code "raw" backtrace (use heuristics
+	from the actual code, rather than symbol table info) - though
+	the idea is Alessandro's. I feel my code is a little cleaner
+	here, particularly in being a little more flexible, such as being
+	able to handle gcc-produced code (which it now can).
+	It also doesn't do frame caching (which is not useful
+	more recent gdb versions).
+	I also used my code for push_/pop_dummy, more or less.
+	I tried to incorporate AF's code for testing sigtramp
+	while backtracing; I probably got it wrong.
+	Added mips_print_register, which tries to scrunch as much
+	information as possible on a screen...
+	Removed the skip-prologue set_cmd. As with hex-disassemble (see
+	under mips-pinsn.c), I don't see anything mips-specific here,
+	and I don't see it being all that useful anyway.
+	
+	tm-mips.h:
+	Added a $fp psuedo-reg distinct from $fp (nice for gcc).
+	Use more register names (rather than hard-cases numbers).
+	
+Thu Sep  6 18:33:15 1990  John Gilmore  (gnu at cygint)
+
+	* Hack up 3.90.11 changes:
+
+	* Makefile.dist (depend): parameterize $(GCC).
+	Add solib.c and solib.o.
+	(readline): Fix vpath for both absolute or relative SRCDIR.
+
+	* blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
+	Also, let the part I didn't understand at least compile so
+	I can test the rest.  FIXME.
+
+	* dbxread.c: Fix thinko using strcmp.
+	(init_psymbol_list): declare static.
+	(partial_symbol_file_open): Comment cleanups better, avoid
+	cleaning up the string table since the caller will do that.
+	Move the stat for mod time into symbol_file_command, temporarily.
+	(There should be a mod time for each symbol file, eventually,
+	to control its rereading.  FIXME.)
+
+	* infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
+	SunOS, which gives error for shared libs otherwise.  (From
+	Schaefer, probably FIXME needs work for portability.)
+
+	* solib.c:  Move #include "param.h" to work.
+	Lowercase all the Uppercase Letters In the Messages.
+	(find_solib): Clean up inferior_so_name for debug printouts.
+	Allow no argument, to mean all shared libraries.
+
+	* symmisc.c: include param.h to get CLEAR_SOLIB.	
+
+Wed Sep  5 18:00:08 1990  John Gilmore  (gnu at cygint)
+
+	* Merge in Kingdon's changes from FSF: the diffs from 3.90.9
+	  to 3.90.11.  ChangeLog entries below are from this.
+
+Wed Jun 13 09:17:39 1990  Jim Kingdon  (kingdon at mole.ai.mit.edu)
+

+
+Mon Jun  4 18:12:31 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)
+
+	* m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
+	Put parens around gcc_p in expansion.
+
+Thu May 24 15:44:51 1990  Jim Kingdon  (kingdon at mole.ai.mit.edu)
+
+	* utils.c (lines_to_list): Return 10 if lines_per_page == 0.
+
+Wed May 23 16:36:04 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)
+
+	* Changes for Sun shared libraries:
+	blockframe.c (find_pc_partial_function): If a non-text symbol
+	is found, set *address = pc - FUNCTION_START_OFFSET.
+	breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
+	Disable breakpoints instead of giving an error.
+	source.c (select_source_symtab): Initialize cs_pst.

+	(record_misc_function): Give correct type for N_DATA symbols.
+	(condense_misc_bunches): do "misc_function_count = j" regardless
+	of inclink.
+	Take code which is shared between symbol_file_command and
+	add_file_command and put it into partial_symbol_file_{open,read}.
+	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.

+
+Tue May 22 17:43:03 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)
+
+	* 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.
+
+	* config.gdb: In list_host, list_target, use ${i}, not $i.
+
+Tue May 15 21:27:12 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)
+
+	* source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
+
+	* sparc-opcode.h: Change all store floating-point state register
+	instructions to have the right match & lose fields.
+
+Sat May  5 12:39:18 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)
+
+	* Makefile.dist: Move -I${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.

+
+	* 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.

+
+	* 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

+	exp_valid_block field correctly.
+
+	* infrun.c (wait_for_inferior): When checking "don't even think

+	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,
