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

Thu Apr  2 00:55:56 1992  John Gilmore  (gnu at cygnus.com)

	* buildsym.c (read_struct_type):  Avoid coredump when C++
	abbreviated type name is messed up.  Reported by Joe Buck.
	FIXME, we need to determine whether GDB or GCC needs to be
	smarter to correctly locate this type name.

	* c-exp.y, coffread.c, command.c, command.h, copying.awk,
	dbxread.c, gdbtypes.c, infcmd.c, inferior.h, infrun.c,

Tue Mar 31 17:48:15 1992  Stu Grossman  (grossman at cygnus.com)

	* mipsread.c (parse_procedure):  PDR.isym should get pointer to

	* mipsread.c (parse_symbol, parse_procedure):  Re-do the way that
	.gdbinfo. symbols are created.  Move creation from parse_procedure
	to parse_symbol, where it is fairly easy to grow the symtab.  This
	also fixes a symtab trashing bug on all mips-based systems.
	* (got_numargs, lookup_numargs, free_numargs):  Delete.  Not
	needed anymore.
	* tm-mips.h, tm-iris3.h, mips-tdep.c, mipsread.c:  Re-do struct

	* Various files: Changed #ifdef IBM6000 to IBM6000_HOST
	or IBM6000_TARGET as (approximately) appropriate.

Sat Mar 28 13:00:10 1992  Fred Fish  (fnf@cygnus.com)

	* objfiles.h (OBJF_SYMS):  Define flag bit for objfile flags.
	* symfile.c (symbol_file_add):  Use OBJF_SYMS to decide  whether

	local instance of struct dbx_symfile_info and replace with DBX_*
	macros.

	must be called prior to any mmalloc calls on the heap.

Thu Mar 26 13:20:06 1992  Per Bothner  (bothner@cygnus.com)

	* rs6000-pinsn.c:  Make dis-assembly output more like
	other targets:  Don't print instruction in hex before

	* command.c, main.c (various places):  Use ctype.h macros
	(such as isupper(x)),  instead of hard-wiring in ASCII-isms
	(such as (x >= 'A' && x <= 'Z')).
	(There are still more of these in other files.)
	* main.c (defined_command):  Lower-case the user's
	new command before entering it.  Needed because
	command lookup is case-insensitive (and also lower-cases).
	(Based on Metin's earlier patch.)

Tue Mar 24 23:27:01 1992  K. Richard Pixley  (rich@cygnus.com)

	* 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
	for OP_SCOPE operand; no point in it now that we use lazy
	reading of values, and use "reference to member" objects.
	* gdbtypes.h:  Clarify comment.
	* valops.c:  Change value_struct_elt_for_address to return
	a reference (or variable), rather than a pointer.  Change
	the name to value_struct_elt_for_reference to reflect this.
	Returning a reference instead of a address provides a
	generalization, since we can use the routine for both
	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
	"reference-to-member" to be printed using the same code.
	* valprint.c (type_print_varspec_prefix):  Avoid printing
	"struct " for domains of class-member types.
	* valops.c (search_struct_field):  Inline code for simplified
	version of value_static_field (which can then be deleted).
	* value.h:  Rename value_struct_elt_for_address to

	for remote MIPS by limiting heuristic to 200 byte search.
	(heuristic_proc_desc):  Byte-swapping.

	gdb/config/mh-irix4 texinfo/configure.in:  Port to SGI Irix-4.x.

Wed Mar  4 11:56:42 1992  Fred Fish  (fnf@cygnus.com)

	* defs.h, utils.c:  xrealloc takes PTR as first arg.

	* defs.h:  Some minor whitespace changes.
	* infrun.c (wait_for_inferior):  Compare int tmp to int 0,

Mon Mar  2 23:00:12 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

	* gdbtypes.c (lookup_pointer_type): initialize the TYPE_LENGTH of

	TYPE_FLAGS of a ptype to TYPE_FLAG_UNSIGNED.
	* tm-h8300.h, h8300-tdep.c, remote-hms.c: personal checkpoint
	* printcmd.c (print_address): if ADDR_BITS_REMOVE is defined, use
	it before printing out the hex shape of an address.

Sun Mar  1 17:41:09 1992  Per Bothner  (bothner@cygnus.com)

	* rs6000-xdep.c (frame_initial_stack_address):  Move
	code to set frame->cache_fsr into new separate function
	frame_get_cacahe_fsr.  This allows fixing a fatal error.
	* xcoffexec.c:  Turn previously suppressed error
	message back on, after cleaning up BFD.

	* breakpoint.c (breakpoint_re_set):  Removed (at least for now)
	printing of blank line, since it cases printing of an
	extra blank line.  Is this intended?  It does mess up
	gdb test suite.
	* defs.h:  Put back declarations of malloc and realloc,
	but protected by #ifndef MALLOC_INCOMPATIBLE.
	* objfiles.c:  Undo previous change:  Use malloc/realloc
	for objfile malloc/realloc fields (but add a cast).
	* xcoffexec.c:  Suppress an error message (for now).

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

	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.

Thu Feb 27 09:26:38 1992  Stu Grossman  (grossman at cygnus.com)

	* breakpoint.c (all_breakpoints_info, breakpoint_1):  Add 'info
	all-breakpoints' command.
	* (get_number):  Allow users to enter negative breakpoint numbers.
	* (breakpoint_1):  Reformat display of 'info break' to show new
	fields.
	* (create_longjmp_breakpoint, breakpoint_re_set,
	breakpoint_re_set_one, enable/disable_longjmp_breakpoint),
	symfile.c  (syms_from_objfile):  Re-do
	insertion of longjmp breakpoints.  Move all code into

	remote-hms.c, remote-mm.c, remote-nindy.c, remote-vx.c, remote.c,
	target.c, target.h, valarith.c, valops.c, value.h, xcoffexec.c:
	Remove to_call_function and target_call_function, since it
	always calls the same thing (call_function_by_hand).
	* core.c, exec.c, solib.c:  Rename target_ops sections =>
	to_sections, etc.
	* infcmd.c, inflow.c, infptrace.c, infrun.c, main.c, target.c,
	target.h:  target_kill takes no args.

	messages when the current language changes.  FIXME.
	* xm-amix.h, xm-i386v4.h, xm-stratus.h: Define NORETURN to avoid
	complaints about volatile functions.
	* xm-sysv4.h (HAVE_MMAP):  Define.

Thu Feb 20 09:04:18 1992  Fred Fish  (fnf at cygnus.com)

	to make prototypes for all functions declared here.
	* cplus-dem.c:  Avoid declaring xmalloc and xrealloc.
	* c-exp.y:  Rename SIGNED, OR, and AND to avoid conflict.

	DIE's.  Add new function read_tag_pointer_type() to read them.

	* dwarfread.c (dwarf_read_array_type, read_subroutine_type):
	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 13 17:14:28 1992  Fred Fish  (fnf at cygnus.com)

	* elfread.c (elf_symtab_read):  Fix code to correctly track
	changes in bfd for absolute symbols.

Thu Feb 13 12:43:29 1992  Stu Grossman  (grossman at cygnus.com)

	* xm-vaxbsd.h:  Close off comment.

	number for double pseudo-registers.

Fri Feb  7 07:56:05 1992  John Gilmore  (gnu at cygnus.com)

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,
	config/mh-vaxbsd, configure.in:  Split up config stuff for Vaxen
	into BSD and Ultrix.

	* dbxread.c (dbx_symfile_init):  Call malloc, not xmalloc.

Sat Feb  1 04:15:41 1992  Stu Grossman  (grossman at cygnus.com)

	* 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.

Sun Jan 26 19:05:40 1992  Per Bothner  (bothner at cygnus.com)

	* 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.

Mon Jan 20 19:06:28 1992  Stu Grossman  (grossman at cygnus.com)

	* main.c (main):  Make option_index local to keep new getopt happy.
	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.

Tue Jan 14 22:34:00 1992  Fred Fish  (fnf at cygnus.com)

	* 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.

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().
