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

Wed Sep  2 01:18:31 1992  John Gilmore  (gnu@cygnus.com)

        * ser-termios.c, ser-go32.c:  Remove DEFUN crap, clean up.
        * serial.h (EXFUN):  Remove all uses, convert to PARAMS.
        * config/sun4os4.mh:  Include ser-termios.o.  FIXME, all .mh files
        should include a ser-XXX.o module.

        * dbxread.c (elfstab_build_psymtabs):  Remove DEFUN crap.
        * 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.*).

Wed Sep  2 00:10:43 1992  John Gilmore  (gnu@cygnus.com)

        * configure.in (*-*-sunos*):  Use trailing * to match all
        sub-variants of SunOS, e.g. sunos4* to match sunos4.1.1.
        (sparc-*-sunos3):  Remove host & target.  Sunos3 never shipped
        in production on Sun-4.
        ({a29k,i[34]86,i960}-*-elf):  Add targets, equivalent to coff.
        (m68k-*-{aout,coff,elf}):  Add targets, w/new config and tm files.
        (sparc-*-{aout,coff,elf}):  Add targets, w/new config and tm files.

        * config/m68k-un.mt, config/m68k-noun.mt, config/sparc-un.mt,
        config/sparc-noun.mt:  New target configs for embedded.
        * config/sun4os3.{mh,mt}:  Remove, never existed in production.

        * tm-68k-un.h, tm-68k-noun.h, tm-spc-un.h, tm-spc-noun.h:  New
        target definitions for embedded with and without underlines on
        identifiers.  FIXME -- this ought to be known by BFD instead.

        * tm-sparc.h, tm-sun2.h, tm-sun3.h:  Delete NAMES_HAVE_UNDERSCORE:
        not a parameter of the CPU, but of the development environment.
        * tm-es1800.h, tm-sunos.h, tm-vx68.h:  Add NAMES_HAVE_UNDERSCORE.

Tue Sep  1 17:31:45 1992  John Gilmore  (gnu@cygnus.com)

        * breakpoint.c (breakpoint_re_set):  Avoid setting source symtab
        (which involves reading in main's symtab) if we have no breakpoints.

Mon Aug 31 13:47:45 1992  Fred Fish  (fnf@cygnus.com)

        * dwarfread.c (cu_language):  New local variable to record
        language for current compilation unit being processed.

        enumerations.
        * dwarfread.c (read_structure_scope):  Synthesize typedefs
        for C++ classes, structs and unions.
        * dwarfread.c (read_enumeration):  Synthesize typedefs for
        C++ enumerations.
        * dwarfread.c (read_file_scope):   Call set_cu_language to
        record language for current compilation unit.  After symtab
        is built, save this recorded language.
        * dwarfread.c (process_dies, add_partial_symbol, struct_type,
        scan_partial_symbols, new_symbol):  Recognize TAG_class_type.
        * dwarfread.c (add_partial_symbol):  Synthesize partial symbol
        typedefs for C++ classes, structs, unions, and enumerations.
        * dwarfread.c (scan_compilation_units):  Call set_cu_language
        to record language for current compilation unit.        
        * dwarfread.c (scan_partial_symbols):  Call add_enum_psymbol here
        for TAG_enumeration_types, rather than in add_partial_symbol.
        * dwarfread.c (add_partial_symbol):  Combine TAG_enumeration_type
        case with class, struct, and union type cases, now that they are
        the same.  Remove tests for non-NULL name attributes, now done
        by callers.
        * gdbtypes.h (TYPE_CODE_CLASS):  Add type for C++ classes, but
        treat as alias for TYPE_CODE_STRUCT for now.

Sun Aug 30 21:32:17 1992  Ian Lance Taylor  (ian@cygnus.com)

        * Makefile.in: map "gdb" through program_transform_name when
        installing.

Sun Aug 30 21:18:51 1992  Fred Fish  (fnf@cygnus.com)

        * {i386-tdep.c, m68k-tdep.c, mips-tdep.c, sparc-tdep.c}
          (supply_gregset, fill_gregset, supply_fpregset, fill_fpregset):
        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,

        * Makefile.in:  Remove demangler stuff.
        * Makefile.in (depend):  Pass -I../readline (needed for main.c).
        * demangle.c (_initialize_demangler):  Tell demangler which
        CPLUS_MARKER to assume.

        xcoff_init_loadinfo, free_loadinfo, xcoff_add_toc_to_loadinfo,
        add_text_to_loadinfo, find_toc_address):  Move from xdep file.
        Use CORE_ADDRs.  Change identifiers to lowercase.

        * rs6000-xdep.c:  Make whole file conditional on native RS/6000,
        supplying dummy routines if non-native.  Add prototype for
        static exec_one_dummy_insn.  Move a mess of functions to
        rs6000-tdep.c (as above).  Remove #if 0'd code.

        * config/rs6000.mh (XDEPFILES):  Move xcoffexec.o to target side.

        * config/{altosgas.mt, i386v-g.mt, i386v32-g.mt}:  Ditto.
        * config/{i386sco.mt,i386v32.mt}:  Remove; identical to i386v.mt.
        * config/{go32.mt,i960.mt}:  Remove; they only printed error msgs.
        * config/nindy960.mt:  Remove useless MT_CFLAGS setting.
        * config/i386aout.mt:  Use tm-i386v.h, not tm-i386v-g.h.

Wed Aug 26 16:02:01 1992  Fred Fish  (fnf@cygnus.com)

        * cplus-dem.c:  Reorder args to most local functions to make them
        follow the consistent pattern of struct work_stuff pointer first,
        followed by pointer into string being demangled, followed by
        pointer to the string where the result is being stored, followed
        by other args.  Also generally replace most variables of name
        "type" with "mangled" for consistency.  They all pointed to the
        same string but half were one name and half the other.
        * cplus-dem.c (LONGERNAMES):  Remove #ifndef's.
        * cplus-dem.c (demangle_qualified):  Rewrite to clean up and allow
        use whenever a qualified name is being demangled.

        * configure.in:  Add sparclite as a target.

        * sparc-stub.c (handle_exception):  Flush instruction cache just

        * infrun.c (handle_command):  Rewrite to allow multiple signal
        numbers, signal number ranges, and to recognize "all" to mean all
        signals except those used by the debugger.
        * infrun.c (SET_SIGS, UNSET_SIGS):  Macros used in handle_command
        to set or reset actions for specific signals.

Sun Aug 23 17:10:07 1992  Fred Fish  (fnf@cygnus.com)

        * coffread.c (decode_type):  Call alloc_type to alloc new
        types.

        to symbol_obstack.
        * gdbtypes.h (TYPE_ALLOC):  New macro to allocate space for data
        associated with a type, using the same mechanism as was used to
        allocate space for the type structure itself.

        * mipsread.c (parse_symbol, parse_type):  Use TYPE_ALLOC.
        * stabsread.c (read_struct_type, read_array_type, read_enum_type,
        read_range_type):  Use TYPE_ALLOC.

Sun Aug 23 11:04:08 1992  Fred Fish  (fnf@cygnus.com)

        * breakpoint.c (breakpoint_re_set):  Select a default source
        symtab if one is not currently selected.
        * utils.c (query):  Call wrap_here before building the output
        query string, to turn off wrapping and flush any buffered output.
        Otherwise our query may end up in the wrap buffer and never be
        seen by the user.
        * eval.c (evaluate_subexp):  Report error when attempting to
        evaluate subscript for types without a target type, rather
        than dumping core by using the NULL pointer.
        * symfile.c (symbol_file_command):  Forget current_source_symtab
        and current_source_line when discarding symbol table.

Sat Aug 22 22:33:20 1992  John Gilmore  (gnu@cygnus.com)

        Bug fixes from Andrew Heybey <ath@lcs.mit.edu>.

        * tm-mips.h (REGISTER_VIRTUAL_TYPE):  Float regs are float type.
        * mips-tdep.c (mips_print_register):  Alloc enough space for two regs.

        * remote.c (remote_open):  Fix baud rate setting to make -b flag
        work.  (remote_wait):  Change 'T' message parser to deal with new
        improved format which allows stub to send an arbitrary bunch of
        registers.
        * sparc-stub.c:  General cleanups.  (trap_low, handle_exception):
        make all this re-entrant by storing all state on the stack.  Clean
        up memory error trapping.  (computeSignal, set_debug_traps):
        make it all table driven.  Make a start at a baud rate setting command.

        * m68k-pinsn.c:  Surround extended support with #ifdef HAVE_68881.

        * infcmd.c (registers_info):  Handle multiple register names.
        Changes inspired by Roland McGrath.

Sat Aug 15 02:28:52 1992  Stu Grossman  (grossman at cygnus.com)

        * sparc-stub.c:  New file.  Mix it with your SPARClite
        application, and it will speak GDB remote protocol!
        * remote.c (remote_wait):  Change 'T' (expedited reply) message to
        deal with arbitrary registers.  Needed for sparc-stub.

        * cplus-dem.c (AUTO_DEMANGLING, GNU_DEMANGLING, LUCID_DEMANGLING):
        Use throughout, instead of checking current_demangling_style.
        * cplus-dem.c (demangle_signature):  When finding an explicit
        start of function args, forget all remembered types for
        lucid/cfront style demangling.
        * cplus-dem.c (demangle_prefix):  In a sequence of two or more
        underbar characters, use last pair as the delimiter.  Hoist
        gnu_special() call up to cplus_demangle().  Call cfront_special()
        when appropriate.
        * cplus-dem.c (cplus_special):  Fix virtual table name demangling
        for inherited classes.

Thu Aug 13 11:54:46 1992  John Gilmore  (gnu at cygnus.com)

        * breakpoint.c (enable_longjmp_breakpoint,
        disable_longjmp_breakpoint, set_longjmp_resume_breakpoint):
        Check for duplicate breakpoints at the same address.  Bug report

        * am29k-tdep.c:  Lint from DECstation compiler.
        * mem-break.c:  Restore test of BREAKPOINT size that Fred removed.
        As the man page says, "Sometimes you just can't get lint to shut
        up".  That doesn't mean you should blow away the code it won't
        shut up about.
        * mips-xdep.c:  Revise stubbing-out of code until Rich cleans
        it up over the next few weeks.  Make mips x 29k build.
        * tm-29k.h (CALL_DUMMY):  Make it work on cross-endian hosts.
        (FIX_CALL_DUMMY):  Comment in the patching of the breakpoint,
        but leave it as a comment because the breakpoint instruction 
        is not easily accessible at this moment (it's static, and if
        we define one here, it goes into every file compiled).

Mon Aug 10 22:27:19 1992  Fred Fish  (fnf@cygnus.com)

        * Makefile.in (VERSION):  Bump to 4.6.3.
        * dwarfread.c (scan_partial_symbols):  Skip over DIE's within

        * symtab.c (lookup_symtab_1, lookup_symbol):  Print compilation
        unit source file name in error message.

        * dwarfread.c (struct_type):  In absence of AT_byte_size for
        bitfield, use size of object of member's type for the size of
        the anonymous object containing the bit field.
        * dwarfread.c (completedieinfo):  Set has_at_byte_size when
        an AT_byte_size attribute is seen.
        * mipsread.c (psymtab_to_symtab_1):  Fix misspelled cast to
        union aux_ext (was aux_ent).

        unsigned char* to char*, for Lucid compiler.
        * i386-tdep.c (codestream_fill):  Fix cast of 2'nd arg to read_memory
        to be correct type (from unsigned char* to char*).
        * valprint.c (type_print_derivation_info):  Minor tweak to placement
        of commas in derived class printing.
        * xcoffread.c (builtin_type):  Fix misspelling in fatal message.

Fri Aug  7 11:18:23 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

        * xm-go32.h: Define LSEEK_NOT_LINEAR
        * serial.c (find_source_lines): if LSEEK_NOT_LINEAR is defined
        then work out the lseek positions of newlines by running through
        the file and `tell'ing.  This makes source file listing work on
        OS's where the relationship between physical position in file and
        canonical position is indeterminate, eg VMS and DOS.

        TYPE_CODE_PTR or TYPE_CODE_REF, dereference it to get the

        TYPE_FLAG_STUB flag.
        * buildsym.c (cleanup_undefined_types):  Don't rely on a

        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".

        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)

        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.

        * dwarfread.c (alloc_utype, decode_subscr_data):  Call alloc_type

        * utils.c (printfi_filtered):  New function.
        * gdbtypes.c (recursive_dump_type):  Use printfi_filtered to

        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.

        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.

        that all cmd lists are owned by main.c.
        * language.c (setchecklist, showchecklist):  Move to main.c, as

        * energize-patches:  Fix minor problems with building energize lib.

        * energize-patches:  Change names of all cadillac procedure calls
        to be energize procedure calls.  Simplify many hooks by moving

        blindly using NULL return value from lookup_symbol.

Sun Jul  5 09:46:43 1992  Stu Grossman  (grossman at cygnus.com)

        * cadillac.c, cadillac-patches:  Rename to energize.c and
        energize-patches.  Change all routines and variables named
        'cadillac*' to 'energize*'.  Create new file called energize.h to
        hold all interface declarations.

        * 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.

        * 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.
        * tm-sun4sol2.h (SUN_FIXED_LBRAC_BUG):  They did (in Sol 2).

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.
        * dwarfread.c:  Conforming changes.  Single offset currently used.
        * elfread.c:  Add various complaints about elf/stab stuff.
        #include gdb-stabs.h.  Conforming changes, using a single 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.

        * dbxread.c (process_one_symbol):  Ignore N_MAIN, N_ENDM for Solaris.
        * 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).

        it work on old preprocessors as well as "picky ANSI" ones.
        * xm-mips.h (memcpy, memset):  Declare, and set MEM_FNS_DECLARED.

        * mips-tdep.c (heuristic_proc_start):  Zero arg produces zero.
        * utils.c (fputs_demangled):  Rename SLOP since DECstation system
        header files define it!

        * tm-29k.h (BREAKPOINT):  Allow it to be overridden with -D.

Sun Jun 28 13:30:22 1992  Fred Fish  (fnf@cygnus.com)

        * 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, the definition is seen as a use of 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

        * remote.c (remote_wait):  Cast signal to void * to avoid warning
        from busted HP compiler.

        * partial-stab.h (N_SO):  Rearrange code a little so that all SO

        (process_coff_symbol: C_TPDEF):  Don't put ordinary foward
        references on opaque type chain; just let coff_lookup_type handle 'em.

        #undeffing them.
        * xm-rs6000.h:  Declare malloc/realloc/free appropriately.  Yet

Thu Jun 18 19:35:22 1992  Fred Fish  (fnf@cygnus.com)

        * valprint.c (type_print_1):  Plug memory leak.  Print all
        C++ syms as demangled, not just functions.
        * buildsym.c (read_range_type):  When we find a signed char
        type, do a lookup of signed char, not plain char.  Plain char's

        * mipsread.c:  Undo ill effects from including <strings.h>,

        * source.c (list_command):  Print demangled function names
        when appropriate.  Fix supplied by Peter Schauer.

        * dbxread.c (end_psymtab):  Only reset texthigh if it's not already
        set.  Don't reset our own texthigh, or dependency-only pst's, in
        scanning all the rest of the psymtabs.
        (process_one_symbol):  Fix comments around N_OBJ, N_OPT, N_UNDF.

        without masking, since it is signed and will later be compared

        functions which handle overwriting of forward-referenced types
        for stabs file reading.
        (lookup_{reference,pointer,function}_type):  These just call
        the make_*_type functions with a null storage alloc parameter.

        forward references will work.
        (read_enum_type):  Force enum values to file scope, due to bug in
        Sun compiler output.  FIXME, fix later.

        Remove unused header_file_prev_index mechanism.  It was already

          /* This code was used before I knew about the instance codes.
             My first hypothesis is that it is not necessary now
             that instance codes are handled.  */

        Foo::Bar::method()).
        Allow the cleaner cfront style of nested class names
        (Q2_3Foo3Bar as well as Q23Foo3Bar).
        Make cplus_demangle re-entrant by removing use of global
        variables.  Instead, place all shared variables in a
        stack-allocated structure, and pass around its address.

        breakpoint instructions that leave PC pointing at the right place.

        * core.c (core_open):  Call warning() to print warnings.

Wed Apr 22 09:55:42 1992  Stu Grossman  (grossman at cygnus.com)

        * symtab.c (lookup_symbol):  Need to check if msymbol->name is
        NULL, as ALL_MSYMBOLS will never return a NULL msymbol pointer.
        This prevents a crash when trying to lookup the value of a
        non-existent symbol.

        * dbxread.c (dbx_symfile_init):  Remove bogus `lvalue cast'.
        * language.h (enum exp_opcode):  Avoid forward enum def.
        * main.c (define_command, user_defined_command):  Lint.
        * mem-break.c, xcoffread.c:  Lint.

        * objfiles.h (OBJF_SYMS):  Define flag bit for objfile flags.
        * symfile.c (symbol_file_add):  Use OBJF_SYMS to decide  whether
        or not to try reading symbols from a mapped objfile.  Plugs memory
        leak due to shared libraries generating no psymtabs or symtabs.

        from the function prototypes, the function definition, and the
        function calls.  These are now available via DBX_STRINGTAB and
        DBX_STRINGTAB_SIZE using the objfile pointer.
        * dbxread.c (dbx_symfile_read):  Relocate addr before using as
        an arg to read_dbx_symtab.
        * dbxread.c (dbx_symfile_read):  Remove code that free'd the
        stringtab and the dbx specific per-objfile private info.
        * dbxread.c (init_psymbol_list):  Remove symbol count from passed
        args in prototype, function definition, and function calls.  It is
        now available via the DBX_SYMCOUNT macro using the objfile
        pointer.
        * dbxread.c (dbx_symfile_read, dbx_symfile_init):  Remove the
        local instance of struct dbx_symfile_info and replace with DBX_*
        macros.
        * dbxread.c (dbx_symfile_read):  Remove init's of now deleted
        symfile_string_table and symfile_string_table_size.

        the stringtab.
        * objfiles.c (allocate_objfile):  Move calls to init_malloc()
        to prior to any calls to mmalloc for the objfile specific heap.
        * utils.c (init_malloc):  Document the requirement that for each
        heap for which corruption checking is desired, that init_mmalloc
        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
        the assembly;  use print_address to print out jump
        destinations.

Wed Mar 25 16:52:35 1992  Per Bothner  (bothner@cygnus.com)

        * c-exp.y, gdbtypes.h:  Add builtin_type_signed_char.

        * configure.in:  fix iris/iris3.

Wed Mar 25 14:55:48 1992  Per Bothner  (bothner@cygnus.com)

        * 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)

        current_objfile.

Tue Mar 24 13:26:25 1992  Per Bothner  (bothner@rtl.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
        value_struct_elt_for_reference.  Delete value_static_field.
        * values.c:  Remove no longer used function value_static_field.

        elfread.c (coff_symfile_finish):  Add function, prototype, and
        add to the xxxx_sym_fns struct for each file type.  Also reformat
        the xxxx_sym_fns vector to a standard format and add comments.
        * coffread.c, mipsread.c, xcoffread.c, coffread.c, dbxread.c,
        elfread.c (xxx_symfile_new_init, xxx_symfile_init, xxx_symfile_read):  
        Pass pointer to struct objfile rather than pointer to sym_fns.
        Change references inside each function accordingly.  Allocate any
        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
        init_header_files(), called from dbx_new_init().
        * dbxread.c (dbx_new_init):  Move deallocation things to new
        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.
        * sparc-tdep.c (get_longjmp_target):  Cast target_read_memory arg.
        * symfile.h:  Move struct sym_fns to before struct objfile def.
        Add sym_finish function pointer and change prototypes of other
        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.
        * symfile.c (syms_from_objfile, symbol_file_add):  Restructured
        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().

Wed Mar 18 15:51:15 1992  Per Bothner  (bothner@cygnus.com)

        Some improvements to g++ debugging.

        * valprint.c (type_print_base):  Fix test for constructor.
        * values.c (value_static_field):  Allow evaluation of

        * remote-mm.c (mm_load):  Symbol_file_add() takes an additional
        arg.
        * remote-vx.c (vx_load_command, add_symbol_stub):
        Symbol_file_add() takes an additional arg.
        * solib.c (symbol_add_stub):  Symbol_file_add() takes an
        additional arg.
        * symfile.c (symfile_open):  Renamed to symfile_bfd_open and
        changed to return a bfd not an objfile pointer.
        * symfile.c (syms_from_objfile): Eliminate local copy of bfd.
        * symfile.c (symbol_file_add):  Takes an additional arg (readnow).
        Change to eliminate local bfd and use symfile_bfd_open() plus
        allocate_objfile().  Add code to implement readnow option.
        * symfile.c (symbol_file_command): Changes to option handling,
        readnow functionality moved to symbol_file_add().
        * symfile.c (symfile_init):  Eliminate local copy of bfd.
        * symfile.c (add_symbol_file_command):  Changes to parse mapped

        printfs.
        * symmisc.c (free_symtab_block):  Now takes and uses current
        objfile pointer.

        * utils.c (init_malloc, malloc_botch, xmalloc, xrealloc):
        Rewrite for new mapped malloc package use.
        * utils.c (mmalloc, mrealloc, mfree):  Stubs for configurations

        * utils.c (xmmalloc, xmrealloc, xmalloc, xrealloc):  Like mmalloc,

        mapped malloc region.
        * utils.c (print_spaces):  Use xmalloc to get the buffer.
        * xm-amix.h, xm-i386v4.h, xm-sun3os4.h, xm-sun4os4.h:  Add defines
        for MMAP_BASE_ADDRESS and MMAP_INCREMENT.
        * config/i386v4.mh:  Insignificant reorganization.

Sat Mar 14 11:44:47 1992  Fred Fish  (fnf@cygnus.com)

        * xcoffread.c:  Only enable compilation of debugging functions
        if IBM6000 is defined.  Fails to compile otherwise.

        Reported by Jim Williams <jimbo@wrs.com>.

Thu Mar 12 11:56:46 1992  Per Bothner  (bothner@cygnus.com)

        Merged in patches from metin@ibmpa.awdpa.ibm.com (Metin G.
        Ozisik) (dated Fri, 6 Mar 92 17:51) for the rs6000.
        * minsyms.c, symfile.c:  Changes that may be generally
        applicable, but are #ifdef IBM6000 for now.

        msymbols().

Fri Mar  6 21:59:34 1992  K. Richard Pixley  (rich@cygnus.com)

        * Makefile.in: added check target.

Thu Mar  5 23:56:01 1992  John Gilmore  (gnu at cygnus.com)

        * ecoff.c:  Move to ../bfd/coff-msym.c.

        (remote_resume):  Mention how to cope with signals.
        (remote_interrupt):  Add debug msg.
        (remote-wait):  Implement new 'T' reply, which includes

Thu Mar  5 12:32:09 1992  Stu Grossman  (grossman at cygnus.com)

        * config.sub configure.in config/.Sanitize config/mh-irix4
        gdb/.Sanitize gdb/configure.in gdb/mips-tdep.c gdb/mipsread.c
        gdb/procfs.c gdb/signame.h gdb/tm-irix3.h gdb/tm-mips.h
        gdb/xm-irix4.h gdb/config/.Sanitize gdb/config/mt-irix3
        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:  Reword confusing comment about ANSI prototypes.
        * defs.h:  Some minor whitespace changes.
        * infrun.c (wait_for_inferior):  Compare int tmp to int 0,
        not NULL, which can be (void *).

        * tm-i386v.h (SP_ARG0):  Define
        * xm-sysv4.h:  Back out of change for missing prototypes.
        * i386-tdep.c (get_longjmp_target):  Add function.

Wed Mar  4 05:46:11 1992  K. Richard Pixley  (rich@rtl.cygnus.com)

        * Makefile.in: install man page too.

Tue Mar  3 15:11:52 1992  Michael Tiemann  (tiemann@cygnus.com)

        * All GDB files that #include defs.h: Removed stdio.h.
        (defs.h): #include stdio.h.

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

        * gdbtypes.c (lookup_pointer_type): initialize the TYPE_LENGTH of
        a ptype to reflect the setting of TARGET_PTR_BIT.  Set the
        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).

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
        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.
        * breakpoint.c (breakpoint_re_set):  Use ALL_BREAKPOINTS_SAFE.
        * symtab.c (find_pc_symtab):  Handle having no objfiles.
        * infcmd.c:  Fix comment.

        * symfile.h (ALL_OBJFILES, ALL_OBJFILES_SAFE):  Add.
        * symfile.c (symbol_file_command):  free all objfiles when
        specifying a new symbol file.
        (reread_symbols):  Stat the file name, don't fstat the descriptor.

Wed Feb 26 18:04:40 1992  K. Richard Pixley  (rich@cygnus.com)

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

Tue Feb 25 19:31:19 1992  Stu Grossman  (grossman at cygnus.com)

        * dbxread.c (end_psymtab):  Delete empty psymtabs.
        * symfile.c (allocate_psymtab):  Recycle empty psymtabs.
        * symfile.h (struct objfile):  Add free_psymtabs.

Sat Feb 22 02:00:32 1992  John Gilmore  (gnu at cygnus.com)

        * Makefile.in (VERSION):  Roll to gdb-4.4.4.

        * symfile.c (symbol_file_command):  strcmp => !strcmp.

        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.
        * language.c (language_info):  Scaffolding to allow briefer
        messages when the current language changes.  FIXME.
        * xm-amix.h, xm-i386v4.h, xm-stratus.h: Define NORETURN to avoid

Mon Feb 17 07:13:27 1992  Fred Fish  (fnf at cygnus.com)

        * dwarfread.c (process_dies):  Add case to handle TAG_pointer_type
        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.

Fri Feb  7 11:51:12 1992  Per Bothner  (bothner at cygnus.com)

        * mips-tdep.c (mips_print_registers):  Print correct register
        number for double pseudo-registers.

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

        * buildsym.c (read_struct_type):  Avoid double-bump of parse ptr
        in the op$::OPERATOR. case.  From Steven McCanne,
        <mccanne@horse.ee.lbl.gov>.

        * exec.c (set_section_name):  Pass arg to exec_files_info;
        only call it if interactive.  From Francis Kauth <fk@tv.tv.tek.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.

Sat Feb  1 04:39:41 1992  John Gilmore  (gnu at cygnus.com)

        * 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.

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.
