[deliverable/binutils-gdb.git] / gdb / ChangeLog

Fri Sep 25 09:52:47 1992  K. Richard Pixley  (rich@sendai.cygnus.com)

        Separate core functions along target vector in preparation for
        native support.  Functions above vector now live in core.c.  Those
        below in corelow.c.

	* core.c (solib_add_stub, core_close, core_open, core_detach,
	  get_core_registers, core_files_info, core_ops): moved to corelow.c
	  (_initialize_core): removed addition of core_ops target.
	* corelow.c: new file.
	(solib_add_stub, core_close, core_open, core_detach,
	get_core_registers, core_files_info, core_ops): moved from core.c
	(_initialize_corelow): new function.
	* gdbcore.h (core_open, core_detach): added prototypes.
	(core_ops): add forward declaration.
	* Makefile.in (SFILES_MAINDIR): add core.c
	(OBS): add core.o
	(TSOBS): change core.o to corelow.o

Wed Sep 23 11:14:53 1992  Stu Grossman  (grossman at cygnus.com)

	* m68k-tdep.c (m68k_saved_pc_after_call):  Use 'GDB_TARGET_IS_SUN3'
	instead of 'sun' predefined symbol so that trap analysis code is
	enabled only when the TARGET is a sun3.

Tue Sep 22 17:13:19 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)

	* tm-i960.h (ext_format_i960): Add top-level declaration.
	(REGISTER_CONVERT_TO_{VIRTUAL,RAW}): Don't declare it in nested
	blocks, else Sun4 compiler complains.

Tue Sep 22 00:43:51 1992  John Gilmore  (gnu@cygnus.com)

	* mips-pinsn.c (print_insn_arg, case 'B'):  Disassemble `break'
	instruction's argument.  Patch from jonathan@cs.stanford.edu
	(Jonathan Stone).

Mon Sep 21 18:16:30 1992  K. Richard Pixley  (rich@sendai.cygnus.com)

	Break the thread of control that implies that a unix child
	process will be the default target.

	* target.c (find_default_run_target, find_default_attach,
	find_default_create_inferior, return_zero):  new functions.
	(cleanup_target):  Make return_zero the default for to_can_run.

	* exec.c (exec_ops), core.c (core_ops):  Replace child_attach and
	child_create_inferior references with find_default_XXX instead.

	(find_default_attach, find_default_create_inferior):  new prototypes.
	(target_can_run): new macro.

	* Also added a zero (default) to_can_run element to all static
	struct target_ops initializations throughout GDB, except: 
	* inftarg.c (child_ops): Use new child_can_run() to enable child runs.

	* infrun.c (child_create_inferior):  Clean up error handling when
	no exec file is specified.
	(child_attach):  Don't require exec file.

Mon Sep 21 19:43:13 1992  John Gilmore and K. Richard Pixley (gnu@cygnus.com)

	Remove kill_inferior_fast, in favor of target_kill, which goes
	through the target vector.

	* inferior.h (kill_inferior_fast): remove declaration.

	* main.c (disconnect): call quit_cover using catch_errors rather
	than calling kill_inferior_fast directly.  New way goes through
	the target vector, handles attached processes, and writes
	command history if appropriate.
	(quit_cover): new function, wrapper for quit_command.

	* convex-xdep.c, go32-xdep.c, hppabsd-xdep.c, hppahpux-xdep.c,

	operands to memory management instructions, from WRS.

Sep 20 08:42:12 1992  Fred Fish  (fnf@cygnus.com)

	* main.c (main):  Back out previous language setting changes.
	Replace with simple default to C before processing any init
	files.  There MUST be a language set, even in the absence of
	init files or executables, or expression parsing fails.

Sat Sep 19 09:52:26 1992  Fred Fish  (fnf@cygnus.com)

	* main.c (main):  Move code that sets initial language to
	symfile.c.  Fixup places where command files are processed to
	be consistent in setting a default language if none has been
	previously set.
	* symfile.c (set_initial_language):  Add code moved from
	main() that sets an initial default language when a new
	symbol file is read.
	* symfile.c (symbol_file_command):  Call set_initial_language.
	* symtab.c (find_main_psymtab):  Add FIXME comment.

	fallthrough bug.

	* rs6000-tdep.c (push_dummy_frame, pop_dummy_frame): replace
	calls to {fetch|store}_inferior_registers with calls to
	target_{fetch|store}_registers, for remote-target independence.

Sat Sep 19 04:23:54 1992  John Gilmore  (gnu@cygnus.com)

	* Makefile.in:  Fix bug I introduced in merging Rich's change.
	* infrun.c (child_create_inferior):  Use proceed() rather than
	doing all the same stuff by hand.

Thu Sep 17 17:35:37 1992  K. Richard Pixley  (rich@sendai.cygnus.com)

	* Makefile.in, configure.in: add support for files used only when
	configured native, that is, when host = target.

Wed Sep 16 23:03:23 1992  K. Richard Pixley  (rich@sendai.cygnus.com)

	* tm-sparc.h, xm-sparc.h: externs and macros relating to deferred

Sat Sep 19 03:14:37 1992  John Gilmore  (gnu@cygnus.com)

	* Makefile.in (gdb-all.texi):  Build in objdir, not $srcdir.

	* config/decstation.mh:  Add MMALLOC_LIB and MMALLOC_DISABLE
	overrides, to avoid problem in xdr_bytes with malloc(0) => 0.

	removed.
	(host_convert_to_virtual, host_convert_from_virtual):  Removed
	forward declarations.
	* target.c (cleanup_target): removed default assignments for
	to_convert_to_virtual and to_convert_from_virtual.

Fri Sep 18 02:07:39 1992  John Gilmore  (gnu@cygnus.com)

	* main.c (gdb_readline):  Avoid printf_filtered, which sets char
	position wrong if used for the prompt.
	* utils.c (puts_filtered):  Comment:  NOT a puts() replacement!

	Support for accessing arbitrary MIPS stack frames in memory.

	* blockframe.c (get_prev_frame_info):  If INIT_FRAME_PC_FIRST is
	set, run it before INIT_EXTRA_FRAME_INFO.
	* stack.c (frame_info):  If PRINT_EXTRA_FRAME_INFO defined, call it.

	* mips-tdep.c (init_extra_frame_info): Only clobber the `frame'
	(FP) value in the frame_info struct if it is zero (as from top of
	execution stack).
	(setup_arbitrary_frame):  Implement FRAME_SPECIFICATION_DYADIC.

	* mips-xdep.c (fetch_inferior_registers):  ZERO_REGNUM always
	comes back as zero.  So does FP_REGNUM, as a trigger for
	init_extra_frame_info.

	* tm-mips.h (INIT_FRAME_PC_FIRST):  Kludge, FIXME, defined to get
	the program counter set before INIT_EXTRA_FRAME_INFO is run.
	(INIT_FRAME_PC):  Defined to null.
	(PRINT_EXTRA_FRAME_INFO): print frame pointer location via symtab.
	(FRAME_SPECIFICATION_DYADIC):  Ask for two args in frame command.
	Briefly explain MIPS stacks in GDB.

Thu Sep 17 03:49:59 1992  John Gilmore  (gnu@cygnus.com)

	* copying.awk, copying.c (show_copying_command,
	show_warranty_command):  Rename from copying_info, warranty_info,
	to match command function conventions.

	* utils.c (prompt_for_continue):  Reinitialize more-counts
	before printing anything, and again afterward.  Fix comments.
	(vfprintf_filtered):  Eliminate static buffer; use auto buffer,
	or alloca() if needed.

	* rs6000-xdep.c:  Use correct conditional (IBM6000_TARGET) to
	detect native versus cross-host.

Wed Sep 16 21:57:14 1992  Stu Grossman  (grossman at cygnus.com)

	* m68k-tdep.c (sun3_saved_pc_after_call):  Only do trap check for
	Suns.  Rename to m68k_saved_pc_after_call.
	* tm-68k-noun.h, tm-sun3.h (SAVED_PC_AFTER_CALL):  Use
	m68k_saved... instead of sun3_saved...

	setup-to-dist, for convenience in rebuilding the depend and
	alldeps.mak files.
	(assorted):  Update to catch straggler files when building gdb.tar.Z.

Tue Sep 15 01:18:50 1992  John Gilmore  (gnu@cygnus.com)

	Preliminary cleanup for splitting host/native/target.

	* infptrace.c (child_resume):  Don't deal with NO_SINGLE_STEP
	here; it is dealt with at a gdb-target-independent level.
	* rs6000-tdep.c (single_step):  Don't call ptrace, we are a
	high toned routine.  Fix return type to void.
	* tm-rs6000.h (AIX_BUGGY_PTRACE_CALL): Zap, we think we fixed it.
	Rich and I believe the "real problem" was that both single_step
	and target_resume were issuing PT_CONTINUE calls.  This would
	cause the second PT_CONTINUE to sometimes fail because the process
	was already running.
	* infptrace.c (child_resume):  Remove AIX_BUGGY_PTRACE_CALL kludge.

Mon Sep 14 19:20:43 1992  Stu Grossman  (grossman at cygnus.com)

	(full_filename):  Don't prepend dirname if filename begins with /.
	(breakpoint_notify, kernel_dispatch):  Deal with DynamicLoad
	messages properly!!
	(getpty (NCR)):  Lotsa bug fixes...
	(kernel_dispatch (case StopRType)):  Use kill() instead of
	killpg() so we can deal with losing systems...
	(wait_for_events):  Work around NCR select() lossage.  It doesn't
	zero out readfds when select() returns zero.
	(energize_initialize):  Use I_SETSIG to get SIGIO interrupts.  Use
	getcwd() instead of getwd() (NCR getwd() seg faults).
	(energize_wait):  Use sigaction() for NCR.  Their version of signal()
	is unreliable by default.

	* procfs.c (proc_wait):  Call print_sys_errmsg() if we get an
	error from PIOCSWSTOP.

	* breakpoint.c, core.c, exec.c, language.c, main.c, printcmd.c,
	symfile.c, target.c, valprint.c:  Use _filtered form of *printf.
	defs.h, utils.c:  Make vfprintf_filtered global.

	* energize.c (send_location):  New routine to consolidate all
	places where we must notify kernel of where the given pc is.
	(cplus_demangle):  Put single-quotes around demangled names.
	(energize_call_command):  Call send_location() after doing up,
	down, and frame commands.

	* doc/gdb.texinfo, doc/gdbinv-m.m4.in, doc/gdbinv-s.m4.in: first
	pass at doc for two new remote targets---29K using UDI, and Tandem
	ST2000 using STDBUG.

	store_inferior_registers):  Replace unexplained numbers
	with manifest constants from a DECstation header file.
	* xm-mips.h (KERNEL_U_ADDR):  Get from <machine/param.h>.
	(REGISTER_U_ADDR):  Fix up for Ultrix 4.2.

	* tm-tahoe.h, xm-tahoe.h (KERNEL_U_ADDR):  Move macro to xm-tahoe.h.

	* stack.c (_initialize_stack):  "dow" should be a valid abbreviation

	they aren't already there.
	* remote-vx.c (vx_prepare_to_store):  Ditto.
	* xcoffread.c:  Surround forward struct defns with #ifdef __STDC__.

Wed Sep  9 16:50:22 1992  John Gilmore  (gnu@cygnus.com)

	* symtab.c (completion_list_add_symbol): restructured to optimize
	for time.  First clip names that cannot match.  Then clip any
	names we've already considered.  Drop a redundant strncpy.  Drop
	a redundant malloc and associated free for demangled names.

Thu Sep  3 09:17:05 1992  Stu Grossman  (grossman at cygnus.com)

	* a68v-xdep.c (store_inferior_registers):  Define as type void.
	* configure.in:  Add host m68k-apollo*-bsd*.
	* demangle.c (struct demanglers):  Use enum instead of constant
	value to keep braindamaged HP/Apollo compiler happy.

Wed Sep  2 20:45:31 1992  Per Bothner  (bothner@rtl.cygnus.com)

	* utils.c (strcmp_iw):  Add a hack to allow "FOO(ARGS)" to
	match "FOO".  This allows 'break Foo' to work when Foo is
	a mangled C++ function.  (See comment before function.)

	* defs.h, i960-pinsn.c, remote-hms.c:  Replace CONST with simple const.

	* configure.in:  Map unrecognized sun 68k's, sun sparcs, into 
	known suns in configure.in, rather than mapping them to unique
	config files that happen to duplicate other config files.
	* config/sun3.{mh,mt}:  Remove (use identical sun3os4.*).
	* config/sun4.{mh,mt}:  Remove (use identical sun4os4.*).

	Use "regi" for local indexing through register numbers, reserving
	"regno" for the name of a specific register passed as an input
	parameter.  Fix bug propagated through all versions that sometimes
	used regno as an index when it should have been regi, thus using
	-1 as an index in some cases.

Sun Aug 30 18:15:17 1992  Per Bothner  (bothner@rtl.cygnus.com)

	* cplus-dem.c, demangle.h:  Moved to ../libiberty and ../include,

	evaluate subscript for types without a target type, rather
	than dumping core by using the NULL pointer.

	standalone demangler to recognize demangling style options.
	* dbxread.c (demangle.h):  Include.
	* dbxread.c (read_ofile_symtab, process_one_symbol):  Set GNU C++

	* gdbtypes.c, gdbtypes.h:  New function lookup_signed_typename.
	* c-exp.y:  Call lookup_signed_typename() after seeing
	"signed".  This handles "signed char" correctly.
	* c-exp.y:  Recognize (but ignore) 'const' and 'volatile'
	keywords before a type specifier.

Fri Jul 10 10:19:52 1992  Fred Fish  (fnf@cygnus.com)

Thu Jul  9 19:05:27 1992  Per Bothner  (bothner@rtl.cygnus.com)

	* gdbtypes.c (lookup_struct_elt_type):  If the input type is
	TYPE_CODE_PTR or TYPE_CODE_REF, dereference it to get the
	target type.  Otherwise, 'whatis this.field' wouldn't work,
	which would be inconsistent, since 'print this.field' works.
	* buildsym.c (read_struct_type, read_enum_type):  Clear
	TYPE_FLAG_STUB flag.
	* buildsym.c (cleanup_undefined_types):  Don't rely on a
	flawed "Reasonable test to see if" a type has been defined
	since it was referred to; now we can just see if the
	TYPE_FLAG_STUB flag has been cleared.
	* valprint.c (print_type_base):  Emit public/protected/private
	labels for methods as well as fields.  Also, indent these labels
	2 spaces instead of 4, for a more conventional "look".
	* symtab.c (gdb_mangle_name):  Undo Fred's change, unless
	GCC_MANGLE_BUG is defined.  Also, handle destructors specially.
	* gcc.patch:  New file.  Contains patch for gcc (so people
	with gdb-2.2.x won't have to wait for a new gcc release).

Thu Jul  9 18:44:26 1992  Ken Raeburn  (raeburn@cygnus.com)

	* i960-pinsn.c (mem): Variables reg[123] should point to CONST.
	(print_addr): Call print_address to show symbolic version as well.

	* remote-vx.c (vx_kill): Don't look for arguments; they aren't
	being passed.
	(vx_read_register): Declare inferior_fp_regs.  Delete code for
	copying "inferior_registers" around; the values are already in var
	"registers".  Use correct size for register set.

	* remote-vx.c (vx_write_register): Don't try writing FP regs; the
	target doesn't support it.
	(vx_read_register): Don't try reading them either.

	* tm-i960.h (IP_REGNUM): Move to end of non-FP list, since the
	VxWorks back end reads them in one contiguous set except for this
	one.
	(register_names): Change "pc" to "pcw" to avoid confusion printing
	"$pc".
	* tm-vx960.h (PC_REGNUM): Use RIP_REGNUM, since that's where we
	find the PC under VxWorks.

	use of various fields.
	* gdbtypes.c (print_bit_vector, print_cplus_stuff):  New functions.
	* c-exp.y (%token):  Add CLASS as a token for C++, add grammar
	production that currently treats it exactly the same as STRUCT.
	* c-exp.y (yylex):  Recognize "class" as token CLASS.
	* symtab.c (gdb_mangle_name):  Rewrite to match current g++ stabs.
	* symtab.c (decode_line_1):  Fix to pass quoted args on down to
	general symbol handling code.  Call cplus_mangle_opname with
	DMGL_ANSI.
	* symtab.c (decode_line_2):  Print demangled function names in
	breakpoint menus, instead of just file and line number.
	* symtab.c (name_match):  Call cplus_demangle with DMGL_ANSI.
	* valprint.c (type_print_base):  Print "class" for C++ classes,
	rather than "struct".  Print section labels for public, protected
	and private members of C++ classes.	
	* values.c:  Include demangle.h.
	* values.c (value_headof):  Call cplus_demangle with DMGL_ANSI.

	* dbxread.c (dbx_symfile_init):  Init stab_section_info to NULL to
	prevent crashes when examining cross-targets.
	* dbxread.c (process_one_symbol):  Include directory name when
	calling start_subfile for SOL & BINCL symbols.  This allows gdb to
	find include files, and yacc/lex sources when the cwd doesn't match
	that in which the object was compiled.
	* objfiles.h (ALL_MSYMBOLS):  Don't seg fault when there are no
	msymbols.
	* symtab.c (lookup_symtab_1):  Rewrite.  It now handles include
	files.

	* maint.c (maintenance_command, maintenance_info_command):
	Install with allow_unknown as 0 and call help_list to show

	* gdbtypes.c (recursive_dump_type):  New function; supports
	maintenance print-type command.
	* gdbtypes.h (recursive_dump_type, maintenance_print_type):
	Add prototypes.
	* main.c (maintenancelist, maintenanceinfolist):  Add maintenance
	command lists.
	* main.c (initialize_cmd_lists):  Eliminate unnecessary casts on

	* printcmd.c (maintenance_print_type):  New maintenance cmd.
	* valprint.c (setprintlist, showprintlist):  Move to main.c, as

	* deblib/connection/*:  Move all of this stuff into energize/, but
	delete unneeded files.

Sun Jul  5 03:06:39 1992  John Gilmore  (gnu at cygnus.com)

	* tm-sysv4.h (NAMES_HAVE_UNDERSCORE):  SVR4 systems don't.

	* buildsym.c (finish_block):  Fix thinko `inner block' complaints.
	* dbxread.c (process_one_symbol):  Parse N_OPT "gcc2_compiled.".
	* procfs.c (proc_set_exec_trap): Set run-on-last-close flag on
	child processes, to avoid dead ones "hanging around" after GDB exits.
	(attach): Always stop the process if it needs it.  Set RLC flag
	when attaching running processes, so it will continue if we detach
	it, quit, or are killed.
	(detach):  Clear faults and set RLC flag to make process run
	when we close it.
	(open_proc_file):  New `mode' argument for O_RDONLY or O_RDWR.
	Callers changed.
	(info_proc):  Open process O_RDONLY, so we can see any process,
	even those controlled by debuggers.

Sat Jul  4 03:43:38 1992  John Gilmore  (gnu at cygnus.com)

	Relocate symbols using an array of section_offsets, rather than a
	single `addr' or `offset'.  This makes Solaris-2 support work, and
	permits better VxWorks (and maybe xcoff) support later.

	* symtab.h (struct section_offsets):  New structure for keeping
	a set of offsets, rather than a single one.
	(struct objfile):  Replace addr with section_offsets member.
	* symfile.h:  Add sym_offsets to struct sym_fns.  Conforming changes.
	* gdb-stabs.h:  New include file with `symbol type specific'
	parameters for psymtabs and objfiles.
	* Makefile.in (HFILES):  Add gdb-stabs.h.
	* buildsym.h (start_psymtab, process_one_symbol):  Fix prototypes.
	* coffread.c:  Conforming changes.  Fake offset array always 0.
	* dbxread.c:  Conforming changes.
	(struct dbx_symfile_info):  Move to gdb-stabs.h.
	(start_psymtab):  Call elfstab_offset_sections to calculate good
	offsets for this source file, based on the ELF symbol table info.
	(read_ofile_symtab):  Yank N_CATCH, which is dead.
	(process_one_symbol, N_CATCH):  Yank.
	(", N_FUN, N_FNAME, N_FN, N_FN_SEQ, N_SO, N_SOL, N_ENTRY):
	Relocate with SECT_OFF_TEXT.
	(", N_STSYM, N_LCSYM, N_ROSYM):  Grope around in the stab string
	to distinguish relocatable from absolute symbols.  Then, if not
	absolute, do:
	(", N_STSYM, N_DSLINE):  SECT_OFF_DATA.
	(", N_LCSYM, N_BSLINE):  SECT_OFF_BSS.
	(", N_ROSYM):  SECT_OFF_RODATA.
	(elfstab_build_psymtabs):  Caller has allocated dbx_symfile_info.
	(dbx_symfile_offsets):  Add to translate addr to offset.

	(elf_symtab_read):  Record info from BSF_FILE symbols, and local
	variables called "Bbss.bss", "Ddata.data", and "Drodata.rodata",
	for later use in building psymtabs.
	(elf_symfile_read):  Allocate dbx_symfile_info here, to keep
	the info collected in elf_symtab_read.  Cleanup calls free_elfinfo.
	(free_elfinfo):  New fn, frees all chained stab_section_infos
	in an objfile, and zaps the start-of-chain pointer.
	(elfstab_offset_sections):  New fn, looks in stab_section_info
	chain to determine section bases to relocate a psymtab's worth
	of symbols, as they are being read.
	* mipsread.c:  Conforming changes.  Stabs-reading will relocate
	using one offset.  MIPS-reading will not relocate at all.
	* partial-stab.h:  Relocate different symbol types using different
	offsets from section_offsets.
	* symfile.c:  Conforming changes.
	(find_lowest_section):  Unused function to use later
	to free us from the Tyranny of the Text Section.
	(syms_from_objfile):  Translate absolute arg ADDR to offsets used
	in all lower layers of symbol reading.  Call format-specific
	sym_offsets function to initialize offsets for high speed symbol
	reading.
	(symbol_file_add):  Call reinit_frame_cache so callers don't have to.
	(symbol_file_command, add_symbol_file_command):  Callers changed.
	* symmisc.c (dump_psymtab):  Print new relocation parameters.
	* xcoffread.c:  Corresponding changes.

	* buildsym.c:  Tidy innerblock_complaint and blockvector_complaint.
	* main.c (main):  Read the $HOME/.gdbinit file before processing
	the argv arguments (e.g. reading symbol files or core
	files).  This allows global parameters to be set, which will apply
	during the symbol reading.  The ./.gdbinit is still read after
	argv processing.
	* symtab.c (list_symbols):  `i variables' shouldn't show enum values.
	* xcoffexec.c:  Clean up quote inside comment.

	* partial-stab.h:  Ignore N_ENDM.
	* elfread.c (elf_symtab_read):  Ignore symbols that don't have a
	CODE or DATA section attachment.  This eliminates a lot of random
	values from shared libraries, which screw up the ordinary symbols
	in the address ranges they happen to overlap.
	* buildsym.c (define_symbol):  Eliminate special tests
	for function types; move into "function" cases in switch statement.
	(define_symbol: 'f', 'F', 'P'):  Process all parameter types
	in case they define new type numbers.  But ignore them (FIXME).
	('k', 'B'):  Ignore const and volatile if we see them (FIXME).

	* remote.c (remote_wait):  Fix cast on signal() call.
	* defs.h (alloca):  More diddling with alloca.  Have to ensure
	that it has a prototype, so that if alloca is defined as a macro

	that takes an arg, to satisfy picky ANSI preprocessors.

Sat Jun 27 12:12:20 1992  Fred Fish  (fnf@cygnus.com)

	* sparc-pinsn.c:  Use <string.h> rather than "string.h", for

	* config/rs6000.mh:  Update (for Fred's new mmalloc)
	flags to disable use of GNU malloc/mmalloc.
	* munch:  Change SYSV rule to allow .text before the label,
	as well as after, to work for AIX.
	* gdbtypes.h:  Minor clarifiction.

Tue Mar 24 07:26:19 1992  Michael Tiemann  (tiemann@cygnus.com)

Thu Mar 19 18:49:45 1992  Per Bothner  (bothner@cygnus.com)

	More C++ improvements (pointers to members, qualified names).
	* c-exp.y:  Support exp.type::name and exp->type::name
	syntaxes.  (Unfortunately, doesn't work for static members.)
	* c-exp.y, eval.c:   Make type::~type work better.
	* eval.c (evaluate_subexp: OP_SCOPE):  Replace use of
	value_static_field by value_struct_elt_for_reference.
	* eval.c (evaluate_subexp):  Merge code for STRUCTOP_MEMBER
	and STRUCTOP_MPTR; cast arg1 to domain-type of arg2.
	* eval.c (evaluate_subexp):  Remove special case for UNOP_ADDR

	class::name as well as &class::name.
	Also, recurse to handle multiple inheritance properly.
	* valprint.c:  Moved code to print pointer-to-members
	to new function point_class_member.  This allows a

	"struct " for domains of class-member types.
	* valops.c (search_struct_field):  Inline code for simplified

	value_struct_elt_for_reference.  Delete value_static_field.
	* values.c:  Remove no longer used function value_static_field.

	symbol file specific info in the per-objfile memory region.
	* dbxread.c (free_and_init_header_files):  Break function into
	free_header_files(), called from dbx_symfile_finish(), and

	dbx_symfile_finish function.
	* elfread.c (elf_new_init):  Call buildsym_new_init().
	* objfiles.c (free_objfile): Call the appropriate symfile_finish()
	routine for the objfile before deallocating other stuff.

	function pointers to reflect passing struct objfile pointer rather
	than struct sym_fns pointer.
	* symfile.c:  Remove now obsolete symtab_fns pointer.
	* symfile.c (symfile_init):  Renamed to find_sym_fns, and now only
	locates the correct sym_fns struct for the given objfile.

	for better support of mapped symbol tables.
	* symfile.c (symbol_file_command):  Remove obsolete code using
	symfile_fns.
	* symfile.h:  Remove duplicate declarations for symfile_objfile,
	entry_point, and object_files.
	* target.c (target_info):  Compare symfile_objfile to NULL.
	* xcoffread.c (aixcoff_new_init):  Move deallocation stuff to
	aixcoff_symfile_finish().

	Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
	[Mail dated Fri, 21 Feb 92 13:14:54 -0800]
	* buildsym.c: Use smash_to_pointer_type() to handle forward type
	references.
	* xcoffread.c: Modifications to C_DECL storage class handling, and
	introduction of an old smash_to_pointer_type() routine.

	Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
	[Mail dated Thu, 20 Feb 92 13:57:16 -0800]
	* rs6000-xdep.c, rs6000-tdep.c, tm-rs6000.h: function_frame_info()
	parameters have been modified.

	Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
	[Mail dated Thu, 20 Feb 92 10:10:05 -0800]
	* rs6000-tdep.c: Before Feb 5 92, register_valid[] array was not used,
	and fetch_inferior_registers() always fetched all the registers
	resulting valid register values at hand all the time. Pushing a dummy
	frame did not require validating all register values first. After
	putting the above mechanism into action, we didn't have valid registers
	values always ready. Thus, all registers need to be fetched before
	pushing a dummy frame now.

	Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
	[Mail dated Thu, 13 Feb 92 16:22:44 -0800]
	* rs6000-xdep.c: frame_initial_stack_address() function to calculate
	the starting address (actual frame address) of a frame.
	* rs6000-tdep.c: modifications to function_frame_info() to see if
	function reserves a frame pointer register (alloca register)
	* tm-rs6000.h: EXTRA_FRAME_INFO, FRAME_ARGS_ADDRESS and
	FRAME_LOCALS_ADDRESS has been updated to support debugging of
	functions with alloca() calls.

Sun Mar  1 13:13:39 1992  Fred Fish  (fnf@cygnus.com)

	* xm-sysv4.h:  Provide definitions/prototypes for host environment
	functions for which no definitions or prototypes are provided in
	any currently included gdb or host environment header files.
	For SVR4, this currently includes malloc and realloc, which cannot
	be portably prototyped in any gdb include file.

Sat Feb 29 14:43:02 1992  Per Bothner  (bothner@cygnus.com)

	* buildsym.h:  Remove obsolete variable file_stabs.

	* Makefile.in:  Move place where configure merges in host-
	and target-dependent fragments later, so the latter
	can override (say) GNU_MALLOC.
	* config/mh-rs6000:  Use system malloc.  Otherwise, I
	ended up with *two* incompatible versions of malloc
	(functions in libc would call the malloc in libc).
	I assume this is a shared library problem.

	* remote.c:  Fix (presumed) typo.
	* objfiles.c:  Use xmalloc/xrealloc instead of
	malloc/realloc (since the latter are no longer declared).

	Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
	[Mail dated Thu, 6 Feb 1992 10:22:02 -0800]
	* rs6000-xdep.c: Improvements to fetch_inferior_registers() to
	handle individual registers.
	* tm-rs6000.h: Fix SAVED_PC_AFTER_CALL macro to handle pc value
	correctly in case it wasn't cached yet. (A problem showed up
	after fetching individual registers.)
	* buildsym.c: Disable type_synonym_name's type name overwriting
	in cases it is unnecesary. rs6000 portation doesn't use
	type_synonym_name, and it used to nullify type names
	* xcoffread.c: to handle g++'s typename abbreviation, fill in a
	type's name as soon as space for that type is allocated.
	* xcoffread.c: ignore a section's lineno information if it is
	not `.text'. (In rs6000 bfd portation integration, skipping over
	`.pad' sections are ignored since it was in machine independent
	part of the code. Thus, a problem of fake sections with invalid
	lineno information arised.)

	Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
	[Mail dated Thu, 6 Feb 1992 13:26:22 -0800]
	* rs6000-tdep.c: make function_frame_info() work whether or not
	reading from a core file.
	* tm-rs6000.h: Implementation of FRAME_FIND_SAVED_REGS macro.

	* infrun.c. main.c, printcmd.c. symtab.c:
	More changes from IBM for rs6000.


Thu Feb 27 22:57:19 1992  Per Bothner  (bothner@cygnus.com)

	* rs6k-opcode.h, tm-rs6000.h, xm-rs6000.h, rs6000-tdep.c,
	rs6000-xdep.c, xcoffexec.c, xcoffread.c:
	Merge in changes (mostly from IBM) for RS6000.
	* breakpoint.c, buildsym.c, infptrace.c, stack.c, symtab.c:
	More changes from IBM for RS6000.  These are in machine-
	independent code, and probably could do with some cleaning
	up.  The most questionable of these are #ifdef IBM6000.
	* infrun.c, sparc-tdep.c: Pass a parameter (signal number)
	to single_step() (for consistency with rs6000 and i860).
	* utils.c:  Allow the 1st arg to xrealloc to be NULL
	(in which case do malloc).  This removes the need for
	some tests in xcoff code (and perhaps other places?).
	* coffread.c: Removed variables last_source_file,
	type_vector, and type_vector_length as these are now
	defined by buildsym.[ch].
	* defs.h:  Remove prototypes for malloc and realloc, since
	these should only be used to implement xmalloc and xrealloc,
	and they conflict with <stdlib.h> in AIX - where they
	return void* even when __STDC__ isn't defined.  Sigh.
	* munch:  Recognize *initialize* in data as well as text
	(AIX uses data).  Also, incorporate a patch from Garrett
	Wollman <wollman@uvm-gen.uvm.edu> to make the sed script
	much more sensible, by only trying to match the name of
	the initialize_foo function, and not the junk before it.
	
Thu Feb 27 20:07:43 1992  Stu Grossman  (grossman at cygnus.com)

	* breakpoint.c (breakpoint_re_set_one):  Don't reset breakpoint
	unless symbol table indicates that something has changed.

Thu Feb 27 11:48:47 1992  John Gilmore  (gnu at cygnus.com)

	* remote.c:  Make it work for embedded MIPS.  Increase buffer
	size, and use throughout.  Round buffer size up if too many regs.
	Support baud rate setting and try for an 8-bit path.  If
	interrupted while waiting for target, send a ^C down the wire.
	Avoid single-byte reads.
	* tm-mips.h:  Add more embedded-system registers to REGISTER_NAMES
	and NUM_REGS.
	* mips-xdep.h:  Avoid the embedded regs when on Unix.

	* mipsread.c:  Byte-swap the symbol table structures, using
	routines from ecoff.c, to read a symbol table written in any
	of the four possible byte orders.
	* configure.in (mips-big-* target):  Same as Sony News.
	* config/mt-bigmips, config/mt-littlemips:  Add ecoff.o.
	* ecoff.c:  New file for symbol swapping routines.

	breakpoint_re_set_one, enable/disable_longjmp_breakpoint),
	symfile.c  (syms_from_objfile):  Re-do
	insertion of longjmp breakpoints.  Move all code into
	breakpoint_re_set, and call that instead of
	create_longjmp_breakpoint in symfile.c.

Thu Feb 27 06:11:05 1992  John Gilmore  (gnu at cygnus.com)

	* breakpoint.h (ALL_BREAKPOINTS_SAFE):  Add.

	* Makefile.in, configure.in: removed traces of namesubdir,
	  -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
	  copyrights to '92, changed some from Cygnus to FSF.

	* printcmd.c:  Use `enum enable' rather than `enum
	display_status'.
	* mipsread.c:  First pass at making it compile with the new
	objfile changes.  Probably seriously broken still, but it
	compiles.  FIXME.

	When creating a new user defined type, check to see if a partial
	type already exists, and if so, bash it to fit.

Fri Feb 14 19:00:17 1992  John Gilmore  (gnu at cygnus.com)

	* coffread.c (decode_base_type):  Pass long, not union.
	Fix by Eric Valette, ev@chorus.fr.

Thu Feb  6 17:41:32 1992  John Gilmore  (gnu at cygnus.com)

	* main.c (print_gdb_version):  Copyright msg: only this year.
	(cd_command):  Avoid changing current_directory on error.

Thu Feb  6 15:14:01 1992  Per Bothner  (bothner at cygnus.com)

	* mipsread.c (parse_partial_symbols):  Handle dependencies
	between partial symbol tables (when not doing stabs-in-ecoff).
	(This used to be handled by parse_fdr, but parse_fdr was
	incompatible with handling stabs-in-ecoff, so the code
	was re-written to not use parse_fdr.  Unfortunately,
	the logic to handle dependencies was overlooked.)

Thu Feb  6 11:51:39 1992  Steve Chamberlain  (sac at rtl.cygnus.com)

	* coffread.c (read_enum_type): Use the size of a target int when
	describing enum.
	* defs.h: added new #define for TARGET_PTR_BIT, defaults to size
	of target int.
	* h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
	* symtab.c (lookup_reference_type, lookup_ptr_type): use
	TARGET_PTR_BIT to determine size of a pointer
	* values.c (unpack_long): when unpacking a REF or a PTR don't
	assume the size of the type.

Wed Feb  5 22:29:59 1992  John Gilmore  (gnu at cygnus.com)

	* mipsread.c (parse_symbol):  Avoid clobbering enum pointer when
	looking at its members.  Improve guess between struct and union,
	only assuming union if multiple members have offsets of zero.

Tue Feb  4 18:05:44 1992  Per Bothner  (bothner at cygnus.com)

	* mipsread.c:  Use (FP0_REGNUM-32) instead of magic number 6.
	(This is just for clarity - and one day permitting us to
	 change FP0_REGNUM from 38 to 32, which would make more sense.)
	* tm-mips.h:  Added STAB_REG_TO_REGNUM macro, so that
	register numbers in stabs-in-ecoff get handled correctly.

Sat Feb  1 04:45:10 1992  Stu Grossman  (grossman at cygnus.com)

 	* xm-vax.h, xm-vaxult.h, xm-vaxbsd.h, config/mh-vaxult,

	* Makefile.in:  Increment version to 4.4.1.
	* main.c (print_gdb_version):  Update copyright notice.

Sat Feb  1 01:43:11 1992  Per Bothner  (bothner at cygnus.com)

	* mipsread.c:  Prepend "struct " to the names of structure
	types, and similarly for enums and unions.  (This used
	to be done, but got lost in the re-write to "guess" the
	difference between enum/struct/union.)
	Also, guess that a tag is an enum if the first member
	has type btNil.

Fri Jan 31 21:45:51 1992  Stu Grossman  (grossman at cygnus.com)

	* xm-vax.h:  #ifndef ultrix around #include of endian.h and
	limits.h (sigh).

Fri Jan 31 00:05:01 1992  John Gilmore  (gnu at cygnus.com)

	* Projects:  Patching executables is done.
	* Makefile.in (VERSION):  Roll to gdb-4.4.
	* README, WHATS.NEW:  Update for gdb-4.4.

	* symfile.c (reread_symbols):  Whenever we reread one object
	file's symbols, we must restart the scan, because the object_files
	chain has been permuted.

	* exec.c (exec_files_info):  Split out into print_section_info.
	Print BFD filename of each section if it's not the default one.
	* core.c (core_files_info):  Call print_section_info.

	* xm-vax.h:  Include a few system header files whose definitions
	must precede defs.h.
	* language.c, language.h:  Make some things const.
	* expression.h, main.c:  const spreads like ooze.

	* mem-break.c (break_insn, break_insn_size):  Use unsigned chars,
	since BREAKPOINT values can be >0x80.

Thu Jan 30 17:21:14 1992  Stu Grossman  (grossman at cygnus.com)

	* infrun.c, xm-i386sco.h:  SCO needs to use setpgid().

Thu Jan 30 01:04:23 1992  John Gilmore  (gnu at cygnus.com)

	* sparc-pinsn.c:  Remove kludge for preferring architectures.
	Remove #ifdef's for SORT_NEEDED.  We need to sort the table, now
	and forever.  Add `add' instruction to the set that get checked
	for a preceding `sethi' in order to print an absolute address.
	Corresponding changes in ../include/opcode/sparc.h needed
	to eliminate garbage instructions.

Wed Jan 29 19:24:34 1992  Per Bothner  (bothner at cygnus.com)

	* mipsread.c (parse_partial_symbols):  Make sure partial
	symbols are created for external symbols (as used to be
	the case).  This is a bit of a pain with the mips-coff.
	It uses a table which points to all of the external
	symbols belonging to a particular FDR or psymtab.
	Once we've generated this table, we might as well save
	it, and then use it in psymtab_to_symtab_1 to find
	the symbols to pass to parse_external().
	* symfile.c,  symfile.c:  New function start_psymtab_common
	to share the common parts of allocating a new psymtab
	for dbxread, mipsread (and later dwarfread).  Its code
	was pulled out from start_psymtab in dbxread.c.
	* dbxread.c (start_psymtab):  Use start_psymtab_common().

	* valprint.c (val_print):  If there is an error when trying
	to print a string, check to see if there really is a problem
	by reading just one character.  If that works, assume
	things are ok.

Wed Jan 29 18:58:43 1992  Stu Grossman  (grossman at cygnus.com)

	* sparc-pinsn.c (compare_opcodes):  Make it prefer v6, v7,
	cypress, v8 mnemonics in that order.

Tue Jan 28 17:32:13 1992  Per Bothner  (bothner at cygnus.com)

	* sparc-pinsn.c:  Put the qsort() back in.

Mon Jan 27 18:51:03 1992  John Gilmore  (gnu at cygnus.com)

	* findvar.c (read_register, write_register):  Handle machines
	where REGISTER_TYPE is not the same size as "int".

	Handle debug symbols in dynamically loaded (relocated) code:

	* dbxread.c (read_ofile_symtab):  Fix up N_CATCH better.  Pass
	offset to process_one_symbol.
	(process_one_symbol):  Take new offset parameter.  Add it into
	appropriate symbol types to relocate symbols to loaded addresses.
	Handle all possible symbol types, and complain() about types that
	we don't expect to see.
	* mipsread.c (psymtab_to_symtab_1):  Pass offset of zero to
	process_one_symbol (FIXME, should pass real offset).

	Misc bugfixes:

	* breakpoint.c (resolve_sal_pc):  Split out code to resolve a
	sal's PC value.
	(set_breakpoint, break_command_1, until_break_command,
	catch_command_1, breakpoint_re_set_one):  Use it.
	* symtab.h (resolve_sal_pc):  Declare.
	* infcmd.c (jump_command):  Use resolve_sal_pc.

	* source.c (list_command):  Shorten "FILE, line N" to "FILE:N".

	* putenv.c (putenv):  Avoid unportably casting pointers to unsigneds.

	* c-exp.y (yylex):  `this' and `template' are only tokens in C++.

	* 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-rtbsd.h, xm-symmetry.h, xm-umax.h:
	Remove MISSING_VPRINTF declaration, and superfluous "kgdb" defines.

Mon Jan 27 15:46:21 1992  Stu Grossman  (grossman at cygnus.com)

	* dbxread.c (process_one_symbol):  Make a first cut at handling
	symbol tables generated by Sun's acc.  (#ifdef'd out, FIXME.)

	* symtab.c (find_pc_line):  Fix stepping into and out of #included
	files.

Mon Jan 27 13:00:55 1992  Stu Grossman  (grossman at cygnus.com)

	* Makefile.in (OPCODES):  Remove OPCODES defs and refs.  There is
	no longer any need to copy ../include/opcode/* into gdb.

Mon Jan 27 12:30:38 1992  John Gilmore  (gnu at cygnus.com)

	* ChangeLog, ChangeLog-9091:  Split ChangeLog at 1992.

	* valprint.c (type_print_base, type_print_method_args):
	Print C++ constructor methods without bogus "return type."

Sat Jan 25 15:57:59 1992  Fred Fish  (fnf at cygnus.com)

	* infptrace.c (child_xfer_memory):  Parameter "target" should
	be a pointer to a structure, not the entire structure.

Fri Jan 24 01:30:27 1992  Fred Fish  (fnf at cygnus.com)

	* depend:  Convert the couple of references to ansidecl.h that
	used the local gdb version to use the ../include version.

Thu Jan 23 22:24:43 1992  Fred Fish  (fnf at cygnus.com)

	* procfs.c
	(child_xfer_memory): Takes pointer to a struct, not entire struct.
	(inferior_proc_init):  Fix non-ANSI version of args.
	(attach):  Call print_sys_errmsg with correct number of args.
	(mappingflags):  Make static, does not need to be global.

	* i386-tdep.c (i386_frame_num_args):  Takes a pointer to a struct
	not the entire struct itself.

	* valops.c (value_assign):  Cast some args to modify_field() and
	{read,write}_register_bytes() correctly.

	* ansidecl.h:  Removed, is duplicate of ../include/ansidecl.h

	* Makefile.in (MALLOCSRC):  Removed reference to removed local
	copy of ansidecl.h.

	* dwarfread.c (list_in_scope):  Needs an initial value, use file
	scope.

	main.c, solib.c, Makefile.in:  Update copyright notices.

Mon Jan 20 08:54:00 1992  Michael Tiemann  (tiemann at cygnus.com)

	* cplus-dem.c (cplus_demangle): Correctly demangle destructors.

Sat Jan 18 17:17:45 1992  Stu Grossman  (grossman at cygnus.com)

	* Makefile.in (HFILES):  Add partial-stab.h.

Sat Jan 18 16:45:01 1992  Fred Fish  (fnf at cygnus.com)

	* config/mh-stratus, config/mt-stratus, tm-stratus.h, xm-stratus.h:
	New files for stratus.  Not complete enough to actually build
	on the Stratus machine; that awaits copyright assignment for
	i860 changes.

	* Makefile.in (USER_CFLAGS):  Add macro specifically reserved
	for getting custom flags into CFLAGS when doing makes.

	* configure.in:  Add config information for stratus.

Thu Jan 16 00:51:46 1992  Fred Fish  (fnf at cygnus.com)

	* dbxread.c (process_one_symbol):  Pass address of structure
	to complain(), rather than the whole structure.

Wed Jan 15 09:56:16 1992  Fred Fish  (fnf at cygnus.com)

	* solib.c (solib_add_common_symbols):  Only compile in when not
	using SVR4 style shared libraries.

	* dwarfread.c (locval):  Add offreg flag to indicate location
	values that are computed off a base register.

	* dwarfread.c (new_symbol):  Rework TAG_global_variable and
	TAG_local_variable cases to account for static variables
	within function scopes.

Tue Jan 14 12:28:52 1992  Stu Grossman  (grossman at cygnus.com)

	* inflow.c:  remove #include <sys/dir.h>.  Not necessary, and
	doesn't exist on some systems.

	* infrun.c (wait_for_inferior!!!!):  Prevent gdb from hanging when
	nexting over recursive function calls.

	* target.c (target_read_string):  Create this routine to read null
	terminated strings from the target.  It deals with running off the
	end of memory elegantly as well.  solib.c (find_solib):  Use
	target_read_string() to avoid problems with running off the end of
	memory.

	* inflow.c (child_terminal_info):  #ifdef TIOCPGRP around lines
	that reference pgrp_inferior.

Mon Jan 13 14:57:11 1992  Per Bothner  (bothner at cygnus.com)

	* tm-mips.h:  Removed BLOCK_ADDRESS_ABSOLUTE, now that
	mips-tfile has been hacked to act more "traditionally."
	* dbxread.c:  Fixed typo in comment.

Sun Jan 12 13:08:36 1992  Per Bothner  (bothner at cygnus.com)

	* mips-tdep.c (mips_skip_prologue):  Add some number of
	'sw' instructions before 'addiu' adjusts the stack.

Fri Jan 10 13:47:06 1992  Fred Fish  (fnf at cygnus.com)

	* dwarfread.c (start_symtab, end_symtab, scopecount, openscope,
	freescope, buildblock closescope, record_line, add_symbol_to_list,
	gatherblocks, make_blockvector):  Extensive changes to switch
	to generic symbol table building code in buildsym.c.  Remove
	scope tree structures and functions, symbol table building
	functions, and lots of other small changes.

	* dwarfread.c:  Add new macros GCC_PRODUCER and STREQN.  Remove
	GCC_COMPILED_FLAG_SYMBOL and GCC2_COMPILED_FLAG_SYMBOL.

Tue Jan  7 13:09:57 1992  Stu Grossman  (grossman at cygnus.com)

	* buildsym.c (cleanup_undefined_types):  Add support for enums.
	This fixes the 'GDB internal error.  cleanup_undefined_types with
	bad type' problem.

Sun Jan  5 09:47:50 1992  Stu Grossman  (grossman at cygnus.com)

	* dbxread.c:  detect gcc2 compilations.

Thu Jan  2 15:07:41 1992  John Gilmore  (gnu at cygnus.com)

	* sparc-pinsn.c:  Rename bitfields that overlap with macro names
	in ../include/opcode/sparc.h.

Wed Jan  1 04:29:00 1992  Fred Fish  (fnf at cygnus.com)

	* Makefile.in:  Change tm-svr4.h to tm-sysv4.h.  Change xm-svr4.h
	to xm-sysv4.h.  Split OPCODE_DIR into OPCODE_DIR1 and OPCODE_DIR2
	to reflect actual locations of opcode files, so TAGS target will
	be buildable.

	* i386-tdep.c:  Change an erroneous 'm68k' reference to 'i386'.

	* i386-tdep.c (supply_fpregset, fill_fpregset):  Remove m68k
	code.

	* m68k-tdep.c (supply_fpregset, fill_fpregset):  Fix array
	dereferencing to access the correct elements.

	* valops.c (value_addr):  Declare return type of external func
	value_copy().

	* xcoffread.c:  Undefine next_symbol_text before redefining it.
