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

Tue Jan 31 12:56:01 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * values.c (modify_field): Changed test for endianness to assign
        to integer and reference character (so that all bits would be
        defined). 

Mon Jan 30 11:41:21 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * news-dep.c: Deleted inclusion of fcntl.h; just duplicates stuff
        found in sys/file.h.

        * i386-dep.c: Included default definition of N_SET_MAGIC for
        COFF_FORMAT.

        * config.gdb: Added checks for several different operating
        systems. 

        * coffread.c (read_struct_type): Put in a flag variable so that
        one could tell when you got to the end of a structure.

        * sun3-dep.c (core_file_command): Changed #ifdef based on SUNOS4
        to ifdef based on FPU.

        * infrun.c (restore_inferior_status): Changed error message to
        "unable to restore previously selected frame".

        * dbxread.c (read_dbx_symtab): Used intermediate variable in error
        message reporting a bad symbol type.  (scan_file_globals,
        read_ofile_symtab, read_addl_syms): Data type of "type" changed to
        unsigned char (which is what it is).
        * i386-dep.c: Removed define of COFF_FORMAT if AOUTHDR is defined.
        Removed define of a_magic to magic (taken care of by N_MAGIC).
        (core_file_command): Zero'd core_aouthdr instead of setting magic
        to zero.
        * i386-pinsn.c: Changed jcxz == jCcxz in jump table.
        (putop): Added a case for 'C'.
        (OP_J): Added code to handle possible masking of PC value on
        certain kinds of data.
        m-i386gas.h: Moved COFF_ENCAPSULATE to before inclusion of
        m-i386.h and defined NAMES_HAVE_UNDERSCORE.

        * coffread.c (unrecrod_misc_function, read_coff_symtab): Added
        symbol number on which error occured to error output.

Fri Jan 27 11:55:04 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * Makefile: Removed init.c in make clean.  Removed it without -f
        and with leading - in make ?gdb.

Thu Jan 26 15:08:03 1989  Randall Smith  (randy at gluteus.ai.mit.edu)

        Changes to get it to work on gould NP1.
        * dbxread.c (read_dbx_symtab): Included cases for N_NBDATA and
        N_NBBSS.
        (psymtab_to_symtab): Changed declaration of hdr to
        DECLARE_FILE_HEADERS.  Changed access to use STRING_TABLE_SIZE and
        SYMBOL_TABLE_SIZE.
        * gld-pinsn.c (findframe): Added declaration of framechain() as
        FRAME_ADDR. 

        * coffread.c (read_coff_symtab): Avoided treating typedefs as
        external symbol definitions.

Wed Jan 25 14:45:43 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * Makefile: Removed reference to alloca.c.  If they need it, they
        can pull alloca.o from the gnu-emacs directory.

        * version.c, gdb.texinfo: Updated version to 3.1 (jumping the gun
        a bit so that I won't forget when I release).

        * m-sun2.h, m-sun2os2.h, m-sun3os4.h, config.gdb: Modified code so
        that default includes new sun core, ptrace, and attach-detach.
        Added defaults for sun 2 os 2.

        Modifications to reset stack limit back to what it used to be just
        before exec.  All mods inside of #ifdef SET_STACK_LIMIT_HUGE.
        * main.c: Added global variable original_stack_limit.
        (main): Set original_stack_limit to original stack limit.
        * inflow.c: Added inclusion of necessary files and external
        reference to original_stack_limit.
        (create_inferior): Reset stack limit to original_stack_limit.

        * dbxread.c (read_dbx_symtab): Killed PROFILE_SYMBOLS ifdef.

        * sparc-dep.c (isabranch): Multiplied offset by 4 before adding it
        to addr to get target.

        * Makefile: Added definition of SHELL to Makefile.

        * m-sun2os4.h: Added code to define NEW_SUN_PTRACE, NEW_SUN_CORE,
        and ATTACH_DETACH.
        * sun3-dep.c: Added code to avoid fp regs if we are on a sun2.

Tue Jan 24 17:59:14 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * dbxread.c (read_array_type): Added function.
        (read_type): Added call to above instead of inline code.

        * Makefile: Added ${GNU_MALLOC} to the list of dependencies for
        the executables.

Mon Jan 23 15:08:51 1989  Randall Smith  (randy at plantaris.ai.mit.edu)

        * gdb.texinfo: Added paragraph to summary describing languages
        with which gdb can be run.  Also added descriptions of the
        "info-methods" and "add-file" commands.

        * symseg.h: Commented a range type as having TYPE_TARGET_TYPE
        pointing at the containing type for the range (often int).
        * dbxread.c (read_range_type): Added code to do actual range types
        if they are defined.  Assumed that the length of a range type is
        the length of the target type; this is a lie, but will do until
        somebody gets back to me as to what these silly dbx symbols mean.
        
        * dbxread.c (read_range_type): Added code to be more picky about
        recognizing builtins as range types, to treat types defined as
        subranges of themselves to be subranges of int, and to recognize
        the char type idiom from dbx as a special case.

Sun Jan 22 01:00:13 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * m-vax.h: Removed definition of FUNCTION_HAS_FRAME_POINTER.
        * blockframe.c (get_prev_frame_info): Removed default definition
        and use of above.  Instead conditionalized checking for leaf nodes
        on FUNCTION_START_OFFSET (see comment in code).

Sat Jan 21 16:59:19 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * dbxread.c (read_range_type): Fixed assumption that integer was
        always type 1.

        * gdb.texinfo: Fixed spelling mistake and added a note in the
        running section making it clear that users may invoke subroutines
        directly from gdb.

        * blockframe.c: Setup a default definition for the macro
        FUNCTION_HAS_FRAME_POINTER.
        (get_prev_frame_info): Used this macro instead of checking
        SKIP_PROLOGUE directly.
        * m-vax.h: Overroad definition; all functions on the vax have
        frame pointers.

Fri Jan 20 12:25:35 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * core.c: Added default definition of N_MAGIC for COFF_FORMAT.

        * xgdb.c: Installed a fix to keep the thing from dying when there
        isn't any frame selected.

        * core.c: Made a change for the UMAX system; needs a different
        file included if using that core format. 

        * Makefile: Deleted duplicate obstack.h in dbxread.c dependency.

        * munch: Modified (much simpler) to cover (I hope) all cases.

        * utils.c (save_cleanups, restore_cleanups): Added functions to
        allow you to push and pop the chain of cleanups to be done.
        * defs.h: Declared the new functions.
        * main.c (catch_errors): Made sure that the only cleanups which
        would be done were the ones put on the chain *after* the current
        location. 

        * m-*.h (FRAME_CHAIN_VALID): Removed check on pc in the current
        frame being valid.
        * blockframe.c (get_prev_frame_info): Made the assumption that if
        a frame's pc value was within the first object file (presumed to
        be /lib/crt0.o), that we shouldn't go any higher.

        * infrun.c (wait_for_inferior): Do *not* execute check for stop pc
        at step_resume_break if we are proceeding over a breakpoint (ie.
        if trap_expected != 0).

        * Makefile: Added -g to LDFLAGS.

        * m-news.h (POP_FRAME) Fixed typo.

        * printcmd.c (print_frame_args): Modified to print out register
        params in order by .stabs entry, not by register number.

        * sparc-opcode.h: Changed declaration of (struct
        arith_imm_fmt).simm to be signed (as per architecture manual).
        * sparc-pinsn.c (fprint_addr1, print_insn): Forced a cast to an
        int, so that we really would get signed behaivior (default for sun
        cc is unsigned).

        * i386-dep.c (i386_get_frame_setup): Replace function with new
        function provided by pace to fix bug in recognizing prologue.

Thu Jan 19 11:01:22 1989  Randall Smith  (randy at plantaris.ai.mit.edu)

        * infcmd.c (run_command): Changed error message to "Program not
        restarted." 

        * value.h: Changed "frame" field in value structure to be a
        FRAME_ADDR (actually CORE_ADDR) so that it could survive across
        calls. 

        * m-sun.h (FRAME_FIND_SAVED_REGS): Fixed a typo.

        * value.h: Added lval: "lval_reg_frame_relative" to indicate a
        register that must be interpeted relative to a frame.  Added
        single entry to value structure: "frame", used to indicate which
        frame a relative regnum is relative to.
        * findvar.c (value_from_register): Modified to correctly setup
        these fields when needed.  Deleted section to fiddle with last
        register copied on little endian machine; multi register
        structures will always occupy an integral number of registers.
        (find_saved_register): Made extern.
        * values.c (allocate_value, allocate_repeat_value): Zero frame
        field on creation.
        * valops.c (value_assign): Added case for lval_reg_frame_relative;
        copy value out, modify it, and copy it back.  Desclared
        find_saved_register as being external.
        * value.h: Removed addition of kludgy structure; thoroughly
        commented file.
        * values.c (free_value, free_all_values, clear_value_history,
        set_internalvar, clear_internavars): Killed free_value.

Wed Jan 18 20:09:39 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * value.h: Deleted struct partial_storage; left over from
        yesterday. 

        * findvar.c (value_from_register): Added code to create a value of
        type lval_reg_partsaved if a value is in seperate registers and
        saved in different places.

Tue Jan 17 13:50:18 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * value.h: Added lval_reg_partsaved to enum lval_type and
        commented enum lval_type.  Commented value structure.
        Added "struct partial_register_saved" to value struct; added
        macros to deal with structure to value.h.
        * values.c (free_value): Created; special cases lval_reg_partsaved
        (which has a pointer to an array which also needs to be free).
        (free_all_values, clear_value_history, set_internalvar,
        clear_internalvars): Modified to use free_values.

        * m-sunos4.h: Changed name to sun3os4.h.
        * m-sun2os4.h, m-sun4os4.h: Created.
        * config.gdb: Added configuration entries for each of the above.
        * Makefile: Added into correct lists.

        * Makefile: Added dependencies on a.out.encap.h.  Made
        a.out.encap.h dependent on a.out.gnu.h and dbxread.c dependent on
        stab.gnu.h. 

        * infrun.c, remote.c: Removed inclusion of any a.out.h files in
        these files; they aren't needed.

        * README: Added comment about bug reporting and comment about
        xgdb. 

        * Makefile: Added note to HPUX dependent section warning about
        problems if compiled with gcc and mentioning the need to add
        -Ihp-include to CFLAGS if you compile on those systems.  Added a
        note about needing the GNU nm with compilers *of gdb* that use the
        coff encapsulate feature also.  * hp-include: Made symbolic link
        over to /gp/gnu/binutils.

        * Makefile: Added TSOBS NTSOBS OBSTACK and REGEX to list of things
        to delete in "make clean".  Also changed "squeakyclean" target as
        "realclean". 

        * findvar.c (value_from_register): Added assignment of VALUE_LVAL
        to be lval_memory when that is appropriate (original code didn't
        bother because it assumed that it was working with a pre lval
        memoried value).

        * expread.y (yylex): Changed to only return type THIS if the
        symbol "$this" is defined in some block superior or equal to the
        current expression context block.

Mon Jan 16 13:56:44 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * m-*.h (FRAME_CHAIN_VALID): On machines which check the relation
        of FRAME_SAVED_PC (thisframe) to first_object_file_end (all except
        gould), make sure that the pc of the current frame also passes (in
        case someone stops in _start).

        * findvar.c (value_of_register): Changed error message in case of
        no inferior or core file.

        * infcmd.c (registers_info): Added a check for inferior or core
        file; error message if not.

        * main.c (gdb_read_line): Modified to take prompt as argument and
        output it to stdout.
        * infcmd.c (registers_info, signals_info), main.c (command_loop,
        read_command_lines, copying_info), symtab.c (decode_line_2,
        output_source_filename, MORE, list_symbols): Changed calling
        convention used to call gdb_read_line.

        * infcmd.c, infrun.c, main.c, symtab.c: Changed the name of the
        function "read_line" to "gdb_read_line".
        * breakpoint.c: Deleted external referenced to function
        "read_line" (not needed by code).

Fri Jan 13 12:22:05 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * i386-dep.c: Include a.out.encap.h if COFF_ENCAPSULATE.
        (N_SET_MAGIC): Defined if not defined by include file.
        (core_file_command): Used N_SET_MAGIC instead of assignment to
        a_magic.
        (exec_file_command): Stuck in a HEADER_SEEK_FD.

        * config.gdb: Added i386-dep.c as depfile for i386gas choice.

        * munch: Added -I. to cc to pick up things included by the param
        file. 

        * stab.gnu.def: Changed name to stab.def (stab.gnu.h needs this name).
        * Makefile: Changed name here also.
        * dbxread.c: Changed name of gnu-stab.h to stab.gnu.h.

        * gnu-stab.h: Changed name to stab.gnu.h.
        * stab.gnu.def: Added as link to binutils.
        * Makefile: Put both in in the distribution.

Thu Jan 12 11:33:49 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * dbxread.c: Made which stab.h is included dependent on
        COFF_ENCAPSULATE; either <stab.h> or "gnu-stab.h".
        * Makefile: Included gnu-stab.h in the list of files to include in
        the distribution.
        * gnu-stab.h: Made a link to /gp/gnu/binutils/stab.h

        * Makefile: Included a.out.gnu.h and m-i386gas.h in list of
        distribution files.
        * m-i386gas.h: Changed to include m-i386.h and fiddle with it
        instead of being a whole new file.
        * a.out.gnu.h: Made a link to /gp/gnu/binutils/a.out.gnu.h.

        Chris Hanson's changes to gdb for hp Unix.
        * Makefile: Modified comments on hpux.
        * hp9k320-dep.c: #define'd WOPR & moved inclusion of signal.h
        * inflow.c: Moved around declaratiosn of <sys/fcntl.h> and
        <sys/ioctl.h> inside of USG depends and deleted all SYSV ifdef's
        (use USG instead).
        * munch: Modified to accept any number of spaces between the T and
        the symbol name.

        Pace's changes to gdb to work with COFF_ENCAPSULATE (robotussin):
        * config.gdb: Added i386gas to targets.
        * default-dep.c: Include a.out.encap.h if COFF_ENCAPSULATE.
        (N_SET_MAGIC): Defined if not defined by include file.
        (core_file_command): Used N_SET_MAGIC instead of assignment to a_magic.
        (exec_file_command): Stuck in a HEADER_SEEK_FD.
        * infrun.c, remote.c: Added an include of a.out.encap.h if
        COFF_ENCAPSULATE defined.  This is commented out in these two
        files, I presume because the definitions aren't used.
        * m-i386gas.h: Created.
        * dbxread.c: Included defintions for USG.
        (READ_FILE_HEADERS): Now uses HEADER_SEEK_FD if it exists.
        (symbol_file_command): Deleted use of HEADER_SEEK_FD.
        * core.c: Deleted extra definition of COFF_FORMAT.
        (N_MAGIC): Defined to be a_magic if not already defined.
        (validate_files): USed N_MAGIC instead of reading a_magic.

Wed Jan 11 12:51:00 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * remote.c: Upped PBUFSIZ.
        (getpkt): Added zeroing of c inside loop in case of error retry.

        * dbxread.c (read_dbx_symtab, process_symbol_for_psymtab): Removed
        code to not put stuff with debugging symbols in the misc function
        list.  Had been ifdef'd out.

        * gdb.texinfo: Added the fact that the return value for a function
        is printed if you use return.

        * infrun.c (wait_for_inferior): Removed test in "Have we hit
        step_resume_breakpoint" for sp values in proper orientation.  Was
        in there for recursive calls in functions without frame pointers
        and it was screwing up calls to alloca.  

        * dbxread.c: Added #ifdef COFF_ENCAPSULATE to include
        a.out.encap.h.
        (symbol_file_command): Do HEADER_SEEK_FD when defined.
        * dbxread.c, core.c: Deleted #ifdef ROBOTUSSIN stuff.
        * robotussin.h: Deleted local copy (was symlink).
        * a.out.encap.h: Created symlink to
        /gp/gnu/binutils/a.out.encap.h.
        * Makefile: Removed robotussin.h and included a.out.encap.h in
        list of files.

        * valprint.c (val_print, print_scalar_formatted): Changed default
        precision of printing float value; now 6 for a float and 16 for a
        double.

        * findvar.c (value_from_register): Added code to deal with the
        case where a value is spread over several registers.  Still don't
        deal with the case when some registers are saved in memory and
        some aren't.

Tue Jan 10 17:04:04 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * xgdb.c (xgdb_create_window): Removed third arg (XtDepth) to
        frameArgs.  

        * infrun.c (handle_command): Error if signal number is less or
        equal to 0 or greater or equal to NSIG or a signal number is not
        provided.

        * command.c (lookup_cmd): Modified to not convert command section
        of command line to lower case in place (in case it isn't a
        subcommand, but an argument to a command).

Fri Jan  6 17:57:34 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * dbxread.c: Changed "text area" to "data area" in comments on
        N_SETV. 

Wed Jan  4 12:29:54 1989  Randall Smith  (randy at gluteus.ai.mit.edu)

        * dbxread.c: Added definitions of gnu symbol types after inclusion
        of a.out.h and stab.h.

Mon Jan  2 20:38:31 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * eval.c (evaluate_subexp): Binary logical operations needed to
        know type to determine whether second value should be evaluated.
        Modified to discover type before binup_user_defined_p branch.
        Also commented "enum noside".

        * Makefile: Changed invocations of munch to be "./munch".

        * gdb.texinfo: Updated to refer to current version of gdb with
        January 1989 last update.

        * coffread.c (end_symtab): Zero context stack when finishing
        lexical contexts.
        (read_coff_symtab): error if context stack 0 in ".ef" else case.

        * m-*.h (FRAME_SAVED_PC): Changed name of argument from "frame" to
        "FRAME" to avoid problems with replacement of "->frame" part of
        macro. 

        * i386-dep.c (i386_get_frame_setup): Added codestream_get() to
        move codestream pointer up to the correct location in "subl $X,
        %esp" case.

Sun Jan  1 14:24:35 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * valprint.c (val_print): Rewrote routine to print string pointed
        to by char pointer; was producing incorrect results when print_max
        was 0.

Fri Dec 30 12:13:35 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * dbxread.c (read_dbx_symtab, process_symbol_for_psymtab): Put
        everything on the misc function list.

        * Checkpointed distribution.

        * Makefile: Added expread.tab.c to the list of things slated for
        distribution. 

Thu Dec 29 10:06:41 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * stack.c (set_backtrace_limit_command, backtrace_limit_info,
        bactrace_command, _initialize_stack): Removed modifications for
        limit on backtrace.  Piping the backtrace through an interuptable
        "more" emulation is a better way to do it.

Wed Dec 28 11:43:09 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * stack.c
        (set_backtrace_limit_command): Added command to set a limit to the
        number of frames for a backtrace to print by default.
        (backtrace_limit_info): To print the current limit.
        (backtrace_command): To use the limit.
        (_initialize_stack): To initialize the limit to its default value
        (30), and add the set and info commands onto the appropriate
        command lists.

        * gdb.texinfo: Documented changes to "backtrace" and "commands"
        commands.

        * stack.c (backtrace_command): Altered so that a negative argument
        would show the last few frames on the stack instead of the first
        few.
        (_initialize_stack): Modified help documentation.

        * breakpoint.c (commands_command): Altered so that "commands" with
        no argument would refer to the last breakpoint set.
        (_initialize_breakpoint): Modified help documentation.

        * infrun.c (wait_for_inferior): Removed ifdef on Sun4; now you can
        single step through compiler generated sub calls and will die if
        you next off of the end of a function.

        * sparc-dep.c (single_step): Fixed typo; "break_insn" ==> "sizeof
        break_insn". 

        * m-sparc.h (INIT_EXTRA_FRAME_INFO): Set the bottom of a stack
        frame to be the bottom of the stack frame inner from this, if that
        inner one is a leaf node.

        * dbxread.c (read_dbx_symtab): Check to make sure we don't add a
        psymtab to it's own dependency list.

        * dbxread.c (read_dbx_symtab): Modified check for duplicate
        dependencies to catch them correctly.

Tue Dec 27 17:02:09 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * m-*.h (FRAME_SAVED_PC): Modified macro to take frame info
        pointer as argument.
        * stack.c (frame_info), blockframe.c (get_prev_frame_info),
        gld-pinsn.c (findframe), m-*.h (SAVED_PC_AFTER_CALL,
        FRAME_CHAIN_VALID, FRAME_NUM_ARGS): Changed usage of macros to
        conform to above.
        * m-sparc.h (FRAME_SAVED_PC), sparc-dep.c (frame_saved_pc):
        Changed frame_saved_pc to have a frame info pointer as an
        argument. 

        * m-vax.h, m-umax.h, m-npl.h, infrun.c (wait_for_inferior),
        blockframe.c (get_prev_frame_info): Modified SAVED_PC_AFTER_CALL
        to take a frame info pointer as an argument.

        * blockframe.c (get_prev_frame_info): Altered the use of the
        macros FRAME_CHAIN, FRAME_CHAIN_VALID, and FRAME_CHAIN_COMBINE to
        use frame info pointers as arguments instead of frame addresses.
        * m-vax.h, m-umax.h, m-sun3.h, m-sun3.h, m-sparc.h, m-pn.h,
        m-npl.h, m-news.h, m-merlin.h, m-isi.h, m-hp9k320.h, m-i386.h:
        Modified definitions of the above macros to suit.
        * m-pn.h, m-npl.h, gould-dep.c (findframe): Modified findframe to
        use a frame info argument; also fixed internals (wouldn't work
        before).

        * m-sparc.h: Cosmetic changes; reordered some macros and made sure
        that nothing went over 80 lines.

Thu Dec 22 11:49:15 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * Version 3.0 released.

        * README: Deleted note about changing -lobstack to obstack.o.

Wed Dec 21 11:12:47 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * m-vax.h (SKIP_PROLOGUE): Now recognizes gcc prologue also.

        * blockframe.c (get_prev_frame_info): Added FUNCTION_START_OFFSET
        to result of get_pc_function_start.
        * infrun.c (wait_for_inferior): Same.

        * gdb.texinfo: Documented new "step" and "next" behavior in
        functions without line number information.

Tue Dec 20 18:00:45 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * infcmd.c (step_1): Changed behavior of "step" or "next" in a
        function witout line number information.  It now sets the step
        range around the function (to single step out of it) using the
        misc function vector, warns the user, and continues.

        * symtab.c (find_pc_line): Zero "end" subsection of returned
        symtab_and_line if no symtab found.

Mon Dec 19 17:44:35 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * i386-pinsn.c (OP_REG): Added code from pace to streamline
        disassembly and corrected types.
        * i386-dep.c
        (i386_follow_jump): Code added to follow byte and word offset
        branches.
        (i386_get_frame_setup): Expanded to deal with more wide ranging
        function prologue.
        (i386_frame_find_saved_regs, i386_skip_prologue): Changed to use
        i386_get_frame_setup. 
        

Sun Dec 18 11:15:03 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * m-sparc.h: Deleted definition of SUN4_COMPILER_BUG; was designed
        to avoid something that I consider a bug in our code, not theirs,
        and which I fixed earlier.  Also deleted definition of
        CANNOT_USE_ARBITRARY_FRAME; no longer used anywhere.
        FRAME_SPECIFICATION_DYADIC used instead.

        * infrun.c (wait_for_inferior): On the sun 4, if a function
        doesn't have a prologue, a next over it single steps into it.
        This gets around the problem of a "call .stret4" at the end of
        functions returning structures.
        * m-sparc.h: Defined SUN4_COMPILER_FEATURE.

        * main.c (copying_info): Seperated the last printf into two
        printfs.  The 386 compiler will now handle it.

        * i386-pinsn.c, i386-dep.c: Moved print_387_control_word,
        print_387_status_word, print_387_status, and i386_float_info to
        dep.c  Also included reg.h in dep.c.

Sat Dec 17 15:31:38 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * main.c (source_command): Don't close instream if it's null
        (indicating execution of a user-defined command).
                 (execute_command): Set instream to null before executing
                 commands and setup clean stuff to put it back on error.

        * inflow.c (terminal_inferior): Went back to not checking the
        ioctl returns; there are some systems when this will simply fail.
        It seems that, on most of these systems, nothing bad will happen
        by that failure.

        * values.c (value_static_field): Fixed dereferencing of null
        pointer. 

        * i386-dep.c (i386_follow_jump): Modified to deal with
        unconditional byte offsets also.

        * dbxread.c (read_type): Fixed typo in function type case of switch.

        * infcmd.c (run_command): Does not prompt to restart if command is
        not from a tty.

Fri Dec 16 15:21:58 1988  Randy Smith  (randy at calvin)

        * gdb.texinfo: Added a third option under the "Cannot Insert
        Breakpoints" workarounds.

        * printcmd.c (display_command): Don't do the display unless there
        is an active inferior; only set it.

        * findvar.c (value_of_register): Added an error check for calling
        this when the inferior isn't active and a core file isn't being
        read. 

        * config.gdb: Added reminder about modifying REGEX in the
        makefile for the 386.

        * i386-pinsn.c, i386-dep.c: Moved m-i386.h helper functions over
        to i386-dep.c.b

Thu Dec 15 14:04:25 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * README: Added a couple of notes about compiling gdb with itself.

        * breakpoint.c (set_momentary_breakpoint): Only takes FRAME_FP of
        frame if frame is non-zero.

        * printcmd.c (print_scalar_formatted): Implemented /g size for
        hexadecimal format on machines without an 8 byte integer type.  It
        seems to be non-trivial to implement /g for other formats.
        (decode_format): Allowed hexadecimal format to make it through /g
        fileter. 

Wed Dec 14 13:27:04 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * expread.y: Converted all calls to write_exp_elt from the parser
        to calls to one of write_exp_elt_{opcode, sym, longcst, dblcst,
        char, type, intern}.  Created all of these routines.  This gets
        around possible problems in passing one of these things in one ear
        and getting something different out the other.  Eliminated
        SUN4_COMPILER_BUG ifdef's; they are now superfluous.

        * symmisc.c (free_all_psymtabs): Reinited partial_symtab_list to 0.
                    (_initialize_symmisc): Initialized both symtab_list and
                    partial_symtab_list.

        * dbxread.c (start_psymtab): Didn't allocate anything on
        dependency list.
        (end_psymtab): Allocate dependency list on psymbol obstack from
        local list.
        (add_psymtab_dependency): Deleted.
        (read_dbx_symtab): Put dependency on local list if it isn't on it
        already.

        * symtab.c: Added definition of psymbol_obstack.
        * symtab.h: Added declaration of psymbol_obstack.
        * symmisc.c (free_all_psymtabs): Added freeing and
        reinitionaliztion of psymbol_obstack.
        * dbxread.c (free_all_psymbols): Deleted.
                    (start_psymtab, end_psymtab,
                    process_symbol_for_psymtab):  Changed most allocation
                    of partial symbol stuff to be off of psymbol_obstack.

        * symmisc.c (free_psymtab, free_all_psymtabs): Deleted
        free_psymtab subroutine.

        * symtab.h: Removed num_includes and includes from partial_symtab
        structure; no longer needed now that all include files have their
        own psymtab.
        * dbxread.c (start_psymtab): Eliminated initialization of above.
                    (end_psymtab): Eliminated finalization of above; get
                    includes from seperate list.
                    (read_dbx_symtab): Moved includes from psymtab list to
                    their own list; included in call to end_psymtab.
        * symmisc.c (free_psymtab): Don't free includes.

Tue Dec 13 14:48:14 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * i386-pinsn.c: Reformatted entire file to correspond to gnu
        software indentation conventions.

        * sparc-dep.c (skip_prologue): Added capability of recognizign
        stores of input register parameters into stack slots. 

        * sparc-dep.c: Added an include of sparc-opcode.h.
        * sparc-pinsn.c, sparc-opcode.h: Moved insn_fmt structures and
        unions from pinsn.c to opcode.h.
        * sparc-pinsn.c, sparc-dep.c (isabranch, skip_prologue): Moved
        this function from pinsn.c to dep.c.

        * Makefile: Put in warnings about compiling with gcc (non-ansi
        include files) and compiling with shared libs on Sunos 4.0 (can't
        debug something that's been compiled that way).

        * sparc-pinsn.c: Put in a completely new file (provided by
        Tiemann) to handle floating point disassembly, load and store
        instructions, and etc. better.  Made the modifications this file
        (ChangeLog) list for sparc-pinsn.c again.

        * symtab.c (output_source_filename): Included "more" emulation hack.

        * symtab.c (output_source_filename): Initialized COLUMN to 0.
                   (sources_info): Modified to not print out a line for
                   all of the include files within a partial symtab (since
                   they have pst's of their own now).  Also modified to
                   make a distinction between those pst's read in and
                   those not.

        * infrun.c: Included void declaration of single_step() if it's
        going to be used.
        * sparc-dep.c (single_step): Moved function previous to use of it.

        * Makefile: Took removal of expread.tab.c out of make clean entry
        and put it into a new "squeakyclean" entry.

Mon Dec 12 13:21:02 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * sparc-pinsn.c (skip_prologue): Changed a struct insn_fmt to a
        union insn_fmt.

        * inflow.c (terminal_inferior): Checked *all* return codes from
        ioctl's and fcntl's in routine.

        * inflow.c (terminal_inferior): Added check for sucess of
        TIOCSPGRP ioctl call.  Just notifies if bad.

        * dbxread.c (symbol_file_command): Close was getting called twice;
        once directly and once through cleanup.  Killed the direct call.  

Sun Dec 11 19:40:40 1988  & Smith  (randy at hobbes.ai.mit.edu)

        * valprint.c (val_print): Deleted spurious printing of "=" from
        TYPE_CODE_REF case.

Sat Dec 10 16:41:07 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * dbxread.c: Changed allocation of psymbols from using malloc and
        realloc to using obstacks.  This means they aren't realloc'd out
        from under the pointers to them.

Fri Dec  9 10:33:24 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * sparc-dep.c inflow.c core.c expread.y command.c infrun.c
        infcmd.c dbxread.c symmisc.c symtab.c printcmd.c valprint.c
        values.c source.c stack.c findvar.c breakpoint.c blockframe.c
        main.c: Various cleanups inspired by "gcc -Wall" (without checking
        for implicit declarations).

        * Makefile: Cleaned up some more.

        * valops.c, m-*.h (FIX_CALL_DUMMY): Modified to take 5 arguments
        as per what sparc needs (programming for a superset of needed
        args).

        * dbxread.c (process_symbol_for_psymtab): Modified to be slightly
        more picky about what it puts on the list of things *not* to be
        put on the misc function list.  When/if I shift everything over to
        being placed on the misc_function_list, this will go away.

        * inferior.h, infrun.c: Added fields to save in inferior_status
        structure. 

        * maketarfile: Deleted; functionality is in Makefile now.

        * infrun.c (wait_for_inferior): Modified algorithm for determining
        whether or not a single-step was through a subroutine call.  See
        comments at top of file.

        * dbxread.c (read_dbx_symtab): Made sure that the IGNORE_SYMBOL
        macro would be checked during initial readin.

        * dbxread.c (read_ofile_symtab): Added macro GCC_COMPILED_FLAG_SYMBOL
        into dbxread.c to indicate what string in a local text symbol will
        indicate a file compiled with gcc.  Defaults to "gcc_compiled.".

Thu Dec  8 11:46:22 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * m-sparc.h (FRAME_FIND_SAVED_REGS): Cleaned up a little to take
        advantage of the new frame cache system.

        * inferior.h, infrun.c, valops.c, valops.c, infcmd.c:  Changed
        mechanism to save inferior status over calls to inferior (eg.
        call_function); implemented save_inferior_info and
        restore_inferior_info.

        * blockframe.c (get_prev_frame): Simplified this by a direct call
        to get_prev_frame_info.

        * frame.h, stack.c, printcmd.c, m-sparc.h, sparc-dep.c: Removed
        all uses of frame_id_from_addr.  There are short routines like it
        still in frame_saved_pc (m-sparc.h) and parse_frame_spec
        (stack.c).  Eventually the one in frame_saved_pc will go away.

        * infcmd.c, sparc-dep.c: Implemented a new mechanism for
        re-selecting the selected frame on return from a call.

        * blockframe.c, stack.c, findvar.c, printcmd.c, m-*.h:  Changed
        all routines and macros that took a "struct frame_info" as an
        argument to take a "struct frame_info *".  Routines: findarg,
        framechain, print_frame_args, FRAME_ARGS_ADDRESS,
        FRAME_STRUCT_ARGS_ADDRESS, FRAME_LOCALS_ADDRESS, FRAME_NUM_ARGS,
        FRAME_FIND_SAVED_REGS.

        * frame.h, stack.c, printcmd.c, infcmd.c, findvar.c, breakpoint.c,
        blockframe.c, xgdb.c, i386-pinsn.c, gld-pinsn.c, m-umax.h,
        m-sun2.h, m-sun3.h, m-sparc.h, m-pn.h, m-npl.h, m-news.h,
        m-merlin.h, m-isi.h, m-i386.h, m-hp9k320.h:  Changed routines to
        use "struct frame_info *" internally.

Wed Dec  7 12:07:54 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * frame.h, blockframe.c, m-sparc.h, sparc-dep.c: Changed all calls
        to get_[prev_]frame_cache_item to get_[prev_]frame_info.

        * blockframe.c: Elminated get_frame_cache_item and
        get_prev_frame_cache_item; functionality now taken care of by
        get_frame_info and get_prev_frame_info.

        * blockframe.c: Put allocation on an obstack and eliminated fancy
        reallocation routines, several variables, and various nasty
        things. 

        * frame.h, stack.c, infrun.c, blockframe.c, sparc-dep.c: Changed
        type FRAME to be a typedef to "struct frame_info *".  Had to also
        change routines that returned frame id's to return the pointer
        instead of the cache index.

        * infcmd.c (finish_command): Used proper method of getting from
        function symbol to start of function.  Was treating a symbol as a
        value. 

        * blockframe.c, breakpoint.c, findvar.c, infcmd.c, stack.c,
        xgdb.c, i386-pinsn.c, frame.h, m-hp9k320.h, m-i386.h, m-isi.h,
        m-merlin.h, m-news.h, m-npl.h, m-pn.h, m-sparc.h, m-sun2.h,
        m-sun3.h, m-umax.h: Changed get_frame_info and get_prev_frame_info
        to return pointers instead of structures.

        * blockframe.c (get_pc_function_start): Modified to go to misc
        function table instead of bombing if pc was in a block without a
        containing function.

        * coffread.c: Dup'd descriptor passed to read_coff_symtab and
        fdopen'd it so that there wouldn't be multiple closes on the same
        fd.  Also put (fclose, stream) on the cleanup list.

        * printcmd.c, stack.c: Changed print_frame_args to take a
        frame_info struct as argument instead of the address of the args
        to the frame.

        * m-i386.h (STORE_STRUCT_RETURN): Decremented sp by sizeof object
        to store (an address) rather than 1.

        * dbxread.c (read_dbx_symtab): Set first_object_file_end in
        read_dbx_symtab (oops).

        * coffread.c (fill_in_vptr_fieldno): Rewrote TYPE_BASECLASS as
        necessary. 

Tue Dec  6 13:03:43 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * coffread.c: Added fake support for partial_symtabs to allow
        compilation and execution without there use.
        * inflow.c: Added a couple of minor USG mods.
        * munch: Put in appropriate conditionals so that it would work on
        USG systems.
        * Makefile: Made regex.* handled same as obstack.*; made sure tar
        file included everything I wanted it to include (including
        malloc.c).

        * dbxread.c (end_psymtab): Create an entry in the
        partial_symtab_list for each subfile of the .o file just read in.
        This allows a "list expread.y:10" to work when we haven't read in
        expread.o's symbol stuff yet.

        * symtab.h, dbxread.c (psymtab_to_symtab): Recognize pst->ldsymlen
        == 0 as indicating a dummy psymtab, only in existence to cause the
        dependency list to be read in.

        * dbxread.c (sort_symtab_syms): Elminated reversal of symbols to
        make sure that register debug symbol decls always come before
        parameter symbols.  After mod below, this is not needed.

        * symtab.c (lookup_block_symbol): Take parameter type symbols
        (LOC_ARG or LOC_REGPARM) after any other symbols which match.

        * dbxread.c (read_type): When defining a type in terms of some
        other type and the other type is supposed to have a pointer back
        to this specific kind of type (pointer, reference, or function),
        check to see if *that* type has been created yet.  If it has, use
        it and fill in the appropriate slot with a pointer to it.

Mon Dec  5 11:25:04 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * symmisc.c: Eliminated existence of free_inclink_symtabs and
        init_free_inclink_symtabs; they aren't called from anywhere, and
        if they were they could disrupt gdb's data structure badly
        (elimination of struct type's which values that stick around past
        elimination of inclink symtabs).

        * dbxread.c (symbol_file_command): Fixed a return pathway out of
        the routine to do_cleanups before it left.

        * infcmd.c (set_environment_command), gdb.texinfo: Added
        capability to set environmental variable values to null.

        * gdb.texinfo: Modified doc on "break" without args slightly.

Sun Dec  4 17:03:16 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * dbxread.c (symbol_file_command): Added check; if there weren't
        any debugging symbols in the file just read, the user is warned.

        * infcmd.c: Commented set_environment_command (a little).

        * createtags: Cleaned up and commented.

        * Makefile: Updated dependency list and cleaned it up somewhat
        (used macros, didn't make .o files depend on .c files, etc.)

Fri Dec  2 11:44:46 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * value.h, values.c, infcmd.c, valops.c, m-i386.h, m-sparc.h,
        m-merlin.h, m-npl.h, m-pn.h, m-umax.h, m-vax.h, m-hp9k320.h,
        m-isi.h, m-news.h, m-sun2.h, m-sun3.h:  Cleaned up dealings with
        functions returning structures.  Specifically: Added a function
        called using_struct_return which indicates whether the function
        being called is using the structure returning conventions or it is
        using the value returning conventions on that machine.  Added a
        macro, STORE_STRUCT_RETURN to store the address of the structure
        to be copied into wherever it's supposed to go, and changed
        call_function to handle all of this correctly.

        * symseg.h, symtab.h, dbxread.c: Added hooks to recognize an
        N_TEXT symbol with name "*gcc-compiled*" as being a flag
        indicating that a file had been compiled with gcc and setting a
        flag in all blocks produced during processing of that file.

Thu Dec  1 13:54:29 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * m-sparc.h (PUSH_DUMMY_FRAME): Saved 8 less than the current pc,
        as POP_FRAME and sparc return convention restore the pc to 8 more
        than the value saved.

        * valops.c, printcmd.c, findvar.c, value.h: Added the routine
        value_from_register, to access a specific register of a specific
        frame as containing a specific type, and used it in read_var_value
        and print_frame_args.

Wed Nov 30 17:39:50 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * dbxread.c (read_number): Will accept either the argument passed
        as an ending character, or a null byte as an ending character.

        * Makefile, createtags: Added entry to create tags for gdb
        distribution which will make sure currently configured machine
        dependent files come first in the list.

Wed Nov 23 13:27:34 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * stack.c, infcmd.c, sparc-dep.c: Modified record_selected_frame
        to work off of frame address.

        * blockframe.c (create_new_frame, get_prev_frame_cache_item):
        Added code to reset pointers within frame cache if it must be
        realloc'd. 

        * dbxread.c (read_dbx_symtab): Added in optimization comparing
        last couple of characters instead of first couple to avoid
        strcmp's in read_dbx_symtab (recording extern syms in misc
        functions or not).  1 call to strlen is balanced out by many fewer
        calls to strcmp.

Tue Nov 22 16:40:14 1988  Randall Smith  (randy at cream-of-wheat.ai.mit.edu)

        * dbxread.c (read_dbx_symtab): Took out optimization for ignoring
        LSYM's; was disallowing typedefs.  Silly me.  

        * Checkpointed distribution (mostly for sending to Tiemann).

        * expression.h: Added BINOP_MIN and BINOP_MAX operators for C++.
        * symseg.h: Included flags for types having destructors and
                constructors, and flags being defined via public and via
                virtual paths.  Added fields NEXT_VARIANT, N_BASECLASSES,
                and BASECLASSES to this type (tr: Changed types from
                having to be derived from a single baseclass to a multiple
                base class).
        * symtab.h: Added macros to access new fields defined in symseg.h.
                Added decl for lookup_basetype_type.
        * dbxread.c 
        (condense_addl_misc_bunches): Function added to condense the misc
                function bunches added by reading in a new .o file.
        (read_addl_syms): Function added to read in symbols
                from a new .o file (incremental linking).
        (add_file_command): Command interface function to indicate
                incrmental linking of a new .o file; this now calls
                read_addl_syms and condense_addl_misc_bunches.
        (define_symbol): Modified code to handle types defined from base
                types which were not known when the derived class was
                output.
        (read_struct_type): Modified to better handle description of
                struct types as derived types.  Possibly derived from
                several different base classes.  Also added new code to
                mark definitions via virtual paths or via public paths.
                Killed seperate code to handle classes with destructors
                but without constructors and improved marking of classes
                as having destructors and constructors.
        * infcmd.c: Modified call to val_print (one more argument).
        * symtab.c (lookup_member_type): Modified to deal with new
                structure in symseg.h.
        (lookup_basetype_type): Function added to find or construct a type
                ?derived? from the given type.
        (decode_line_1): Modified to deal with new type data structures.
                Modified to deal with new number of args for
                decode_line_2.
        (decode_line_2): Changed number of args (?why?).
        (init_type): Added inits for new C++ fields from
                symseg.h.
        *valarith.c
        (value_x_binop, value_binop): Added cases for BINOP_MIN &
                BINOP_MAX.
        * valops.c
        (value_struct_elt, check_field, value_struct_elt_for_address):
                Changed to deal with multiple possible baseclasses.
        (value_of_this): Made SELECTED_FRAME an extern variable.
        * valprint.c
        (val_print): Added an argument DEREF_REF to dereference references
                automatically, instead of printing them like pointers.
                Changed number of arguments in recursive calls to itself.
                Changed to deal with varibale numbers of base classes.
        (value_print): Changed number of arguments to val_print.  Print
                type of value also if value is a reference.
        (type_print_derivation_info): Added function to print out
                derivation info a a type.
        (type_print_base): Modified to use type_print_derivation_info and
                to handle multiple baseclasses.
        
Mon Nov 21 10:32:07 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * inflow.c (term_status_command): Add trailing newline to output. 

        * sparc-dep.c (do_save_insn, do_restore_insn): Saved
        "stop_registers" over the call for the sake of normal_stop and
        run_stack_dummy.

        * m-sparc.h (EXTRACT_RETURN_VALUE): Put in parenthesis to force
        addition of 8 to the int pointer, not the char pointer.

        * sparc-pinsn.c (print_addr1): Believe that I have gotten the
        syntax right for loads and stores as adb does it.

        * symtab.c (list_symbols): Turned search for match on rexegp into
        a single loop.

        * dbxread.c (psymtab_to_symtab): Don't read it in if it's already
        been read in.

        * dbxread.c (psymtab_to_symtab): Changed error to fatal in
        psymtab_to_symtab. 

        * expread.y (parse_number): Fixed bug which treated 'l' at end of
        number as '0'.

Fri Nov 18 13:57:33 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * dbxread.c (read_dbx_symtab, process_symbol_for_psymtab): Was
        being foolish and using pointers into an array I could realloc.
        Converted these pointers into integers.

Wed Nov 16 11:43:10 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * m-sparc.h (POP_FRAME): Made the new frame be PC_ADJUST of the
        old frame.

        * i386-pinsn.c, m-hp9k320.h, m-isi.h, m-merlin.h, m-news.h,
        m-npl.h, m-pn.h, m-sparc.h, m-sun2.h, m-sun3.h, m-umax.h, m-vax.h:
        Modified POP_FRAME to use the current frame instead of
        read_register (FP_REGNUM) and to flush_cached_frames before
        setting the current frame.  Also added a call to set the current
        frame in those POP_FRAMEs that didn't have it.

        * infrun.c (wait_for_inferior): Moved call to set_current_frame up
        to guarrantee that the current frame will always be set when a
        POP_FRAME is done.  

        * infrun.c (normal_stop): Added something to reset the pc of the
        current frame (was incorrect because of DECR_PC_AFTER_BREAK).

        * valprint.c (val_print): Changed to check to see if a string was
        out of bounds when being printed and to indicate this if so.

        * convex-dep.c (read_inferior_memory): Changed to return the value
        of errno if the call failed (which will be 0 if the call
        suceeded). 

Tue Nov 15 10:17:15 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * infrun.c (wait_for_inferior): Two changes: 1) Added code to
        not trigger the step breakpoint on recursive calls to functions
        without frame info, and 2) Added calls to distinguish recursive
        calls within a function without a frame (which next/nexti might
        wish to step over) from jumps to the beginning of a function
        (which it generally doesn't).

        * m-sparc.h (INIT_EXTRA_FRAME_INFO): Bottom set correctly for leaf
        parents. 

        * blockframe.c (get_prev_frame_cache_item): Put in mod to check
        for a leaf node (by presence or lack of function prologue).  If
        there is a leaf node, it is assumed that SAVED_PC_AFTER_CALL is
        valid.  Otherwise, FRAME_SAVED_PC or read_pc is used.

        * blockframe.c, frame.h: Did final deletion of unused routines and
        commented problems with getting a pointer into the frame cache in
        the frame_info structure comment.

        * blockframe.c, frame.h, stack.c: Killed use of
        frame_id_from_frame_info; used frame_id_from_addr instead.

        * blockframe.c, frame.h, stack.c, others (oops): Combined stack
        cache and frame info structures.

        * blockframe.c, sparc-dep.c, stack.c: Created the function
        create_new_frame and used it in place of bad calls to
        frame_id_from_addr. 

        * blockframe.c, inflow.c, infrun.c, i386-pinsn.c, m-hp9k320.h,
        m-npl.h, m-pn.h, m-sparc.h, m-sun3.h, m-vax.h, default-dep.c,
        convex-dep.c, gould-dep.c, hp9k320-dep.c, news-dep.c, sparc-dep.c,
        sun3-dep.c, umax-dep.c: Killed use of
        set_current_Frame_by_address.  Used set_current_frame
        (create_new_frame...) instead.

        * frame.h: Killed use of FRAME_FP_ID.

        * infrun.c, blockframe.c: Killed select_frame_by_address.  Used
        select_frame (get_current_frame (), 0) (which was correct in all
        cases that we need to worry about.

Mon Nov 14 14:19:32 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * frame.h, blockframe.c, stack.c, m-sparc.h, sparc-dep.c: Added
        mechanisms to deal with possible specification of frames
        dyadically. 

Sun Nov 13 16:03:32 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)

        * ns32k-opcode.h: Add insns acbw, acbd.

Sun Nov 13 15:09:58 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * breakpoint.c: Changed breakpoint structure to use the address of
        a given frame (constant across inferior runs) as the criteria for
        stopping instead of the frame ident (which varies across inferior
        calls). 

Fri Nov 11 13:00:22 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * gld-pinsn.c (findframe): Modified to work with the new frame
        id's.  Actually, it looks as if this routine should be called with
        an address anyway.

        * findvar.c (find_saved_register): Altered bactrace loop to work
        off of frames and not frame infos.

        * frame.h, blockframe.c, stack.c, sparc-dep.c, m-sparc.h: Changed
        FRAME from being the address of the frame to being a simple ident
        which is an index into the frame_cache_item list.
        * convex-dep.c, default-dep.c, gould-dep.c, hp9k320-dep.c,
        i386-pinsn.c, inflow.c, infrun.c, news-dep.c, sparc-dep.c,
        sun3-dep.c, umax-dep.c, m-hp9k320.h, m-npl.h, m-pn.h, m-sparc.h,
        m-sun3.h, m-vax.h: Changed calls of the form set_current_frame
        (read_register (FP_REGNUM)) to set_current_frame_by_address (...). 

Thu Nov 10 16:57:57 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * frame.h, blockframe.c, gld-pinsn.c, sparc-dep.c, stack.c,
        infrun.c, findvar.c, m-sparc.h: Changed the FRAME type to be
        purely an identifier, using FRAME_FP and FRAME_FP_ID to convert
        back and forth between the two.  The identifier is *currently*
        still the frame pointer value for that frame.

Wed Nov  9 17:28:14 1988  Chris Hanson  (cph at kleph)

        * m-hp9k320.h (FP_REGISTER_ADDR): Redefine this to return
        difference between address of given FP register, and beginning of
        `struct user' that it occurs in.

        * hp9k320-dep.c (core_file_command): Fix sign error in size
        argument to myread.  Change buffer argument to pointer; was
        copying entire structure.
        (fetch_inferior_registers, store_inferior_registers): Replace
        occurrences of `FP_REGISTER_ADDR_DIFF' with `FP_REGISTER_ADDR'.
        Flush former definition.

Wed Nov  9 12:11:37 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * xgdb.c: Killed include of initialize.h.

        * Pulled in xgdb.c from the net.

        * Checkpointed distribution (to provide to 3b2 guy).

        * coffread.c, dbxread.c, symmisc.c, symtab.c, symseg.h: Changed
        format of table of line number--pc mapping information.  Can
        handle negative pc's now.

        * command.c: Deleted local copy of savestring; code in utils.c is
        identical. 

Tue Nov  8 11:12:16 1988  Randall Smith  (randy at plantaris.ai.mit.edu)

        * gdb.texinfo: Added documentation for shell escape.

Mon Nov  7 12:27:16 1988  Randall Smith  (randy at sugar-bombs.ai.mit.edu)

        * command.c: Added commands for shell escape.

        * core.c, dbxread.c: Added ROBOTUSSIN mods.

        * Checkpointed distribution.

        * printcmd.c (x_command): Yanked error if there is no memory to
        examine (could be looking at executable straight).

        * sparc-pinsn.c (print_insn): Amount to leftshift sethi imm by is
        now 10 (matches adb in output).

        * printcmd.c (x_command): Don't attempt to set $_ & $__ if there
        is no last_examine_value (can happen if you did an x/0).

Fri Nov  4 13:44:49 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * printcmd.c (x_command): Error if there is no memory to examine.

        * gdb.texinfo: Added "cont" to the command index.

        * sparc-dep.c (do_save_insn): Fixed typo in shift amount.

        * m68k-opcode.h: Fixed opcodes for 68881.

        * breakpoint.c, infcmd.c, source.c: Changed defaults in several
        places for decode_line_1 to work off of the default_breakpoint_*
        values instead of current_source_* values (the current_source_*
        values are off by 5 or so because of listing defaults).

        * stack.c (frame_info): ifdef'd out FRAME_SPECIFCATION_DYADIC in
        the stack.c module.  If I can't do this right, I don't want to do
        it at all.  Read the comment there for more info.

Mon Oct 31 16:23:06 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * gdb.texinfo: Added documentation on the "until" command.

        it. 

        * breakpoint.c, infcmd.c, infrun.c: Added new field to breakpoint
        structure (silent, indicating a silent breakpoint), and modified
        breakpoint_stop_status and things that read it's return value to
        understand it.

Fri Oct 28 17:45:33 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * dbxread.c, symmisc.c: Assorted speedups for readin, including
        special casing most common symbols, and doing buffering instead of
        calling malloc.  

Thu Oct 27 11:11:15 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * stack.c, sparc-dep.c, m-sparc.h: Modified to allow "info frame"
        to take two arguments on the sparc and do the right thing with
        them. 

        * dbxread.c (read_dbx_symtab, process_symbol_for_psymtab): Put
        stuff to put only symbols that didn't have debugging info on the
        misc functions list back in.

Wed Oct 26 10:10:32 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * valprint.c (type_print_varspec_suffix): Added check for
        TYPE_LENGTH(TYPE_TARGET_TYPE(type)) > 0 to prevent divide by 0.

        * printcmd.c (print_formatted): Added check for VALUE_REPEATED;
        value_print needs to be called for that.

        * infrun.c (wait_for_inferior): Added break when you decide to
        stop on a null function prologue rather than continue stepping.

        * m-sun3.h: Added explanatory comment to REGISTER_RAW_SIZE.

        * expread.y (parse_c_1): Initialized paren_depth for each parse.

Tue Oct 25 14:19:38 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * valprint.c, coffread.c, dbxread.c: Enum constant values in enum
        type now accessed through TYPE_FIELD_BITPOS.

        * dbxread.c (process_symbol_for_psymtab): Added code to deal with
        possible lack of a ":" in a debugging symbol (do nothing).

        * symtab.c (decode_line_1): Added check in case of all numbers for
        complete lack of symbols.

        * source.c (select_source_symtab): Made sure that this wouldn't
        bomb on complete lack of symbols.

Mon Oct 24 12:28:29 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * m-sparc.h, findvar.c: Ditched REGISTER_SAVED_UNIQUELY and based
        code on REGISTER_IN_WINDOW_P and HAVE_REGISTER_WINDOWS.  This will
        break when we find a register window machine which saves the
        window registers within the context of an inferior frame.

        * sparc-dep.c (frame_saved_pc): Put PC_ADJUST return back in for
        frame_saved_pc.  Seems correct.

        * findvar.c, m-sparc.h: Created the macro REGISTER_SAVED_UNIQUELY
        to handle register window issues (ie. that find_saved_register
        wasn't checking the selected frame itself for shit). 

        * sparc-dep.c (core_file_command): Offset target of o & g register
        bcopy by 1 to hit correct registers.

        * m-sparc.h: Changed STACK_END_ADDR.

Sun Oct 23 19:41:51 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * sparc-dep.c (core_file_command): Added in code to get the i & l
        registers from the stack in the corefile, and blew away some wrong
        code to get i & l from inferior.

Fri Oct 21 15:09:19 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

        * m-sparc.h (PUSH_DUMMY_FRAME): Saved the value of the RP register
        in the location reserved for i7 (in the created frame); this way
        the rp value won't get lost.  The pc (what we put into the rp in
        this routine) gets saved seperately, so we loose no information.

        * sparc-dep.c (do_save_insn & do_restore_insn): Added a wrapper to
        preserve the proceed status state variables around each call to
        proceed (the current frame was getting munged because this wasn't
        being done).

        * m-sparc.h (FRAME_FIND_SAVED_REGS): Fix bug: saved registers
        addresses were being computed using absolute registers number,
        rather than numbers relative to each group of regs.

        * m-sparc.h (POP_FRAME): Fixed a bug (I hope) in the context
        within which saved reg numbers were being interpetted.  The
        values to be restored were being gotten in the inferior frame, and
        the restoring was done in the superior frame.  This means that i
        registers must be restored into o registers.

        * sparc-dep.c (do_restore_insn): Modified to take a pc as an
        argument, instead of a raw_buffer.  This matches (at least it
        appears to match) usage from POP_FRAME, which is the only place
        from which do_restore_insn is called.

        * sparc-dep.c (do_save_insn and do_restore_insn): Added comments.

        * m-sparc.h (FRAME_FIND_SAVED_REGS): Modified my code to find the
        save addresses of out registers to use the in regs off the stack
        pointer when the current frame is 1 from the innermost.

Thu Oct 20 13:56:15 1988  & Smith  (randy at hobbes.ai.mit.edu)

        * blockframe.c, m-sparc.h: Removed code associated with
        GET_PREV_FRAME_FROM_CACHE_ITEM.  This code was not needed for the
        sparc; you can always find the previous frames fp from the fp of
        the current frame (which is the sp of the previous).  It's getting
        the information associated with a given frame (ie. saved
        registers) that's a bitch, because that stuff is saved relative to
        the stack pointer rather than the frame pointer.

        * m-sparc.h (GET_PREV_FRAME_FROM_CACHE_ITEM): Modified to return
        the frame pointer of the previous frame instead of the stack
        pointer of same.

        * blockframe.c (flush_cached_frames): Modified call to
        obstack_free to free back to frame_cache instead of back to zero.
        This leaves the obstack control structure in finite state (and
        still frees the entry allocated at frame_cache).

Sat Oct 15 16:30:47 1988  & Smith  (randy at tartarus.uchicago.edu)

        * valops.c (call_function): Suicide material here.  Fixed a typo;
        CALL_DUMMY_STACK_ADJUST was spelled CAll_DUMMY_STACK_ADJUST on
        line 530 of the file.  This cost me three days.  I'm giving up
        typing for lent.

Fri Oct 14 15:10:43 1988  & Smith  (randy at tartarus.uchicago.edu)

        * m-sparc.h: Corrected a minor mistake in the dummy frame code
        that was getting the 5th argument and the first argument from the
        same place.

Tue Oct 11 11:49:33 1988  & Smith  (randy at tartarus.uchicago.edu)

        * infrun.c: Made stop_after_trap and stop_after_attach extern
        instead of static so that code which used proceed from machine
        dependent files could fiddle with them.

        * blockframe.c, frame.h, sparc-dep.c, m-sparc.h: Changed sense of
        ->prev and ->next in struct frame_cache_item to fit usage in rest
        of gdb (oops).

Mon Oct 10 15:32:42 1988  Randy Smith  (randy at gargoyle.uchicago.edu)

        * m-sparc.h, sparc-dep.c, blockframe.c, frame.h: Wrote
        get_frame_cache_item.  Modified FRAME_SAVED_PC and frame_saved_pc
        to take only one argument and do the correct thing with it.  Added
        the two macros I recently defined in blockframe.c to m-sparc.h.
        Have yet to compile this thing on a sparc, but I've now merged in
        everything that I received from tiemann, either exactly, or simply
        effectively. 

        * source.c: Added code to allocated space to sals.sals in the case
        where no line was specified.

        * blockframe.c, infrun.c: Modified to cache stack frames requested
        to minimize accesses to subprocess.

Tue Oct  4 15:10:39 1988  Randall Smith  (randy at cream-of-wheat.ai.mit.edu)

        * config.gdb: Added sparc.

Mon Oct  3 23:01:22 1988  Randall Smith  (randy at cream-of-wheat.ai.mit.edu)

        * Makefile, blockframe.c, command.c, core.c, dbxread.c, defs.h,
        expread.y, findvar.c, infcmd.c, inflow.c, infrun.c, sparc-pinsn.c,
        m-sparc.h, sparc-def.c, printcmd.c, stack.c, symmisc.c, symseg.h,
        valops.c, values.c: Did initial merge of sparc port.  This will
        not compile; have to do stack frame caching and finish port.

        * inflow.c, gdb.texinfo: `tty' now resets the controling terminal. 

Fri Sep 30 11:31:16 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * inferior.h, infcmd.c, infrun.c: Changed the variable
        stop_random_signal to stopped_by_random signal to fit in better
        with name conventions (variable is not a direction to the
        proceed/resume set; it is information from it).

Thu Sep 29 13:30:46 1988  Randall Smith  (randy at cream-of-wheat.ai.mit.edu)

        * infcmd.c (finish_command): Value type of return value is now
        whatever the function returns, not the type of the function (fixed
        a bug in printing said value).

        * dbxread.c (read_dbx_symtab, process_symbol_for_psymtab):
        Put *all* global symbols into misc_functions.  This is what was
        happening anyway, and we need it for find_pc_misc_function.

        ** This was eventually taken out, but I didn't mark it in the
        ChangeLog.  Oops.

        * dbxread.c (process_symbol_for_psymtab): Put every debugger
        symbol which survives the top case except for constants on the
        symchain.  This means that all of these *won't* show up in misc
        functions (this will be fixed once I make sure it's broken the way
        it's supposed to be).

        * dbxread.c: Modified placement of debugger globals onto the hash
        list; now we exclude the stuff after the colon and don't skip the
        first character (debugger symbols don't have underscores).

        * dbxread.c: Killed debuginfo stuff with ifdef's.

Wed Sep 28 14:31:51 1988  Randall Smith  (randy at cream-of-wheat.ai.mit.edu)

        * symtab.h, dbxread.c: Modified to deal with BINCL, EINCL, and
        EXCL symbols produced by the sun loader by adding a list of
        pre-requisite partial_symtabs that each partial symtab needs.

        * symtab.h, dbxread.c, symtab.c, symmisc.c: Modified to avoid
        doing a qsort on the local (static) psymbols for each file to
        speed startup.  This feature is not completely debugged, but it's
        inclusion has forced the inclusion of another feature (dealing
        with EINCL's, BINCL's and EXCL's) and so I'm going to go in and
        deal with them.

        * dbxread.c (process_symbol_for_psymtab): Made sure that the class
        of the symbol made it into the partial_symbol entry.

Tue Sep 27 15:10:26 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * dbxread.c: Fixed bug; init_psymbol_list was not being called
        with the right number of arguments (1).

        * dbxread.c: Put ifdef's around N_MAIN, N_M2C, and N_SCOPE to
        allow compilation on a microvax.

        * config.gdb: Modified so that "config.gdb vax" would work.

        * dbxread.c, symtab.h, symmisc.h, symtab.c, source.c: Put in many
        and varied hacks to speed up gdb startup including: A complete
        rewrite of read_dbx_symtab, a modification of the partial_symtab
        data type, deletion of select_source_symtab from
        symbol_file_command, and optimiztion of the call to strcmp in
        compare_psymbols. 

Thu Sep 22 11:08:54 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * dbxread.c (psymtab_to_symtab): Removed call to
        init_misc_functions. 

        * dbxread.c: Fixed enumeration type clash (used enum instead of
        integer constant).

        * breakpoint.c: Fixed typo; lack of \ at end of line in middle of
        string constant. 

        * symseg.h: Fixed typo; lack of semicolon after structure
        definition. 

        * command.c, breakpoint.c, printcmd.c: Added cmdlist editing
        functions to add commands with the abbrev flag set.  Changed
        help_cmd_list to recognize this flag and modified unset,
        undisplay, and enable, disable, and delete breakpoints to have
        this flag set.

Wed Sep 21 13:34:19 1988  Randall Smith  (randy at plantaris.ai.mit.edu)

        * breakpoint.c, infcmd.c, gdb.texinfo: Created "unset" as an alias
        for delete, and changed "unset-environment" to be the
        "environment" subcommand of "delete".

        * gdb.texinfo, valprint.c: Added documentation in the manual for
        breaking the set-* commands into subcommands of set.  Changed "set
        maximum" to "set array-max".

        * main.c, printcmd.c, breakpoint.c: Moved the declaration of
        command lists into main and setup a function in main initializing
        them to guarrantee that they would be initialized before calling
        any of the individual files initialize routines.

        * command.c (lookup_cmd): A null string subcommand is treated as
        an unknown subcommand rather than an ambiguous one (eg. "set $x =
        1" will now work).

        * infrun.c (wait_for_inferior): Put in ifdef for Sony News in
        check for trap by INNER_THAN macro.

        * eval.c (evaluate_subexp): Put in catch to keep the user from
        attempting to call a non function as a function.

Tue Sep 20 10:35:53 1988  Randall Smith  (randy at oatmeal.ai.mit.edu)

        * dbxread.c (read_dbx_symtab): Installed code to keep track of
        which global symbols did not have debugger symbols refering to
        them, and recording these via record_misc_function.

        * dbxread.c: Killed code to check for extra global symbols in the
        debugger symbol table.

        * printcmd.c, breakpoint.c: Modified help entries for several
        commands to make sure that abbreviations were clearly marked and
        that the right commands showed up in the help listings.

        * main.c, command.c, breakpoint.c, infcmd.c, printcmd.c,
        valprint.c, defs.h: Modified help system to allow help on a class
        name to show subcommands as well as commands and help on a command
        to show *all* subcommands of that command.

Fri Sep 16 16:51:19 1988  Randall Smith  (randy at gluteus.ai.mit.edu)

        * breakpoint.c (_initialize_breakpoint): Made "breakpoints"
        subcommands of enable, disable, and delete use class 0 (ie. they
        show up when you do a help xxx now).

        * infcmd.c,printcmd,c,main.c,valprint.c: Changed the set-*
        commands into subcommands of set.  Created "set variable" for use
        with variables whose names might conflict with other subcommands.

        * blockframe.c, dbxread.c, coffread.c, expread.y, source.c:
        Fixed mostly minor (and one major one in block_for_pc) bugs
        involving checking the partial_symtab_list when a scan through the
        symtab_list fails.

Wed Sep 14 12:02:05 1988  Randall Smith  (randy at sugar-smacks.ai.mit.edu)

        * breakpoint.c, gdb.texinfo: Added enable breakpoints, disable
        breakpoints and delete breakpoints as synonyms for enable,
        disable, and delete.  This seemed reasonable because of the
        immeninent arrival of watchpoints & etc.

        * gdb.texinfo: Added enable display, disable display, and delete
        display to manual.

Tue Sep 13 16:53:56 1988  Randall Smith  (randy at sugar-smacks.ai.mit.edu)

        * inferior.h, infrun.c, infcmd.c: Added variable
        stop_random_signal to indicate when a proceed had been stopped by
        an unexpected signal.  Used this to determine (in normal_stop)
        whether the current display point should be deleted.

        * valops.c: Fix to value_ind to check for reference before doing a
        COERCE_ARRAY.

Sun Jul 31 11:42:36 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)

        * breakpoint.c (_initialize_breakpoint): Clean up doc for commands
        that can now apply also to auto-displays.

        * coffread.c (record_line): Corrected a spazz in editing.
        Also removed the two lines that assume line-numbers appear
        only in increasing order.

Tue Jul 26 22:19:06 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)

        * expression.h, eval.c, expprint.c, printcmd.c, valarith.c,
        valops.c, valprint.c, values.c, m-*.h: Changes for evaluating and
        displaying 64-bit `long long' integers.  Each machine must define
        a LONGEST type, and a BUILTIN_TYPE_LONGEST.

        * symmisc.c: (print_symtab) check the status of the fopen and call
        perror_with_name if needed.

Thu Jul 21 00:56:11 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)

        * Convex: core.c: changes required by Convex's SOFF format were
        isolated in convex-dep.c.

Wed Jul 20 21:26:10 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)

        * coffread.c, core.c, expread.y, i386-pinsn.c, infcmd.c, inflow.c,
        infrun.c, m-i386.h, main.c, remote.c, source.c, valops.c:
        Improvements for the handling of the i386 and other machines
        running USG.  (Several of these files just needed extra header files
        such as types.h.) utils.c: added bcopy, bcmp, bzero, getwd, list
        of signals, and queue routines for USG systems.  Added vfork macro
        to i386

        * printcmd.c, breakpoint.c: New commands to enable/disable
        auto-displays.  Also `delete display displaynumber' works like
        `undisplay displaynumber'.

Tue Jul 19 02:17:18 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)

        * coffread.c: (coff_lookup_type)  Wrong portion of type_vector was
        being bzero'd after type_vector was reallocated.

        * printcmd.c: (delete_display) Check for a display chain before
        attempting to delete a display.

        * core.c, *-dep.c (*-infdep moved to *-dep): machine-dependent
        parts of core.c (core_file_command, exec_file_command) moved to
        *-dep.c. 

Mon Jul 18 19:45:51 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)

        * dbxread.c: typo in read_struct_type (missing '=') was causing a
        C struct to be parsed as a C++ struct, resulting in a `invalid
        character' message.

Sun Jul 17 22:27:32 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)

        * printcmd.c, symtab.c, valops.c, expread.y: When an expression is
        read, the innermost block required to evaluate the expression is
        saved in the global variable `innermost_block'.  This information
        is saved in the `block' field of an auto-display so that
        expressions with inactive variables can be skipped.  `info display'
        tells the user which displays are active and which are not.  New
        fn `contained_in' returns nonzero if one block is contained within
        another. 

Fri Jul 15 01:53:14 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)

        * infrun.c, m-i386.h: Use macro TRAPS_EXPECTED to set number of
        traps to skip when sh execs the program.  Default is 2, m-i386.h
        overrides this and sets to 4.

        * coffread.c, infrun.c: minor changes for the i386.  May be able
        to eliminate them with more general code.

        * default-infdep.c: #ifdef SYSTEMV, include header file types.h.
        Also switched the order of signal.h and user.h, since System 5
        requires signal.h to come first.

        * core.c main.c, remote,c, source.c, inflow.c: #ifdef SYSTEMV,
        include various header files.  Usually types.h and fcntl.h.

        * utils.c: added queue routines needed by the i386 (and other sys
        5 machines).

        * sys5.c, regex.c, regex.h: new files for sys 5 systems.  (The
        regex files are simply links to /gp/gnu/lib.)

Thu Jul 14 01:47:14 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)

        * config.gdb, README: Provide a list of known machines when user
        enters an invalid machine.  New second arg is operating system,
        currently only used with `sunos4' or `os4'. Entry for i386 added.

        * news-infdep.c: new file.

        * m-news.h: new version which deals with new bugs in news800's OS.

Tue Jul 12 19:52:16 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)

        * Makefile, *.c, munch, config.gdb, README: New initialization
        scheme uses nm to find functions whose names begin with
        `_initialize_'.  Files `initialize.h', `firstfile.c',
        `lastfile.c', `m-*init.h' no longer needed. 

        * eval.c, symtab.c, valarith.c, valops.c, value.h, values.c: Bug
        fixes from gdb+ 2.5.4.  evaluate_subexp takes a new arg, type
        expected. New fn value_virtual_fn_field.

Mon Jul 11 00:48:49 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)

        * core.c (read_memory): xfer_core_file was being called with an
        extra argument (0) by read_memory.

        * core.c (read_memory), *-infdep.c (read_inferior_memory),
        valops.c (value_at): read_memory and read_inferior_memory now work
        like write_memory and write_inferior_memory in that errno is
        checked after each ptrace and returned to the caller.  Used in
        value_at to detect references to addresses which are out of
        bounds.  Also core.c (xfer_core_file): return 1 if invalid
        address, 0 otherwise.

        * inflow.c, <machine>-infdep.c: removed all calls to ptrace from
        inflow.c and put them in machine-dependent files *-infdep.c.

        * symmisc.c: (read_symsegs) Accept only format number 2.  Since
        the size of the type structure changed when C++ support was added,
        format 1 can no longer be used.

        * core.c, m-sunos4.h: (core_file_command) support for SunOS 4.0.
        Slight change in the core structure.  #ifdef SUNOS4.  New file
        m-sunos4.h.  May want to change config.gdb also.

Fri Jul  8 19:59:49 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)

        * breakpoint.c: (break_command_1) Allow `break if condition'
        rather than parsing `if' as a function name and returning an
        error.

Thu Jul  7 22:22:47 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)

        * C++: valops.c, valprint.c, value.h, values.c: merged code to deal
        with C++ expressions.

Wed Jul  6 03:28:18 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)

        * C++: dbxread.c: (read_dbx_symtab, condense_misc_bunches,
        add_file_command)  Merged code to read symbol information from
        an incrementally linked file.  symmisc.c:
        (init_free_inclink_symtabs, free_inclink_symtabs) Cleanup
        routines.

Tue Jul  5 02:50:41 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)

        * C++: symtab.c, breakpoint.c, source.c:  Merged code to deal with
        ambiguous line specifications.  In C++ one can have overloaded
        function names, so that `list classname::overloadedfuncname'
        refers to several different lines, possibly in different files.

Fri Jul  1 02:44:20 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)

        * C++: symtab.c: replaced lookup_symtab_1 and lookup_symtab_2 with
        a modified lookup_symbol which checks for fields of the current
        implied argument `this'.  printcmd.c, source.c, symtab.c,
        valops.c: Need to change callers once callers are
        installed. 

Wed Jun 29 01:26:56 1988  Peter TerMaat  (pete at frosted-flakes.ai.mit.edu)

        * C++: eval.c, expprint.c, expread.y, expression.h, valarith.c, 
        Merged code to deal with evaluation of user-defined operators,
        member functions, and virtual functions.
        binop_must_be_user_defined tests for user-defined binops, 
        value_x_binop calls the appropriate operator function. 

Tue Jun 28 02:56:42 1988  Peter TerMaat  (pete at frosted-flakes.ai.mit.edu)

        * C++: Makefile: changed the echo: expect 101 shift/reduce conflicts 
        and 1 reduce/reduce conflict.
