1057
 
1058
        * printcmd.c (_initialize_printcmd): Changed "undisplay" not to
1059
        have abbrev flag set; it isn't an abbreviation of "delete
1060
        display", it's an alias.

        Check it before calling query.

1078
        call to strcmp.
1079
 
1080
        * gdb.texinfo (Command editing): @include inc-readline.texinfo

1099
        or "union " from type names before doing comparison
1100

1116
        * valprint.c (val_print): Made sure that all returns returned a

        bounds.
1128
 
1129

1130
        gcc and localized inclusion of alloca.h on the sparc with the
1131
        other alloca stuff.
1132
        * command.c: Doesn't need to include alloca.h on the sparc; defs.h

        does it for you.
1134
 
1135
        * printcmd.c (print_frame_args): Changed test for call to
1136

1145
 
1146
        * m-newsos3.h: Define BROKEN_LARGE_ALLOCA.
1147

1151
 
1152
        * m68k-opcode.h: moved some of the fmovem entries so they're
1153
        all consecutive.  This way the assembler doesn't bomb.

1156
 
1157
        * symtab.c (lookup_symbol): Changed error to an informational (if
1158
        not very comforting) message about internal problems.  This will
1159
        get a null symbol returned to decode_line_1, which should force
1160
        things to be looked up in the misc function vector.
1161
 
1162
Wed Jul 19 13:47:34 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
1163
 
1164
        * symtab.c (lookup_symbol): Changed "fatal" to "error" in
1165
        external symbol not found in symtab in which it was supposed to be
1166
        found.  This can be reached because of a bug in ar.

Tue Jul 18 22:57:43 1989  Randy Smith  (roland at hobbes.ai.mit.edu)
1169
 
1170
        * m-news.h [REGISTER_U_ADDR]: Decreased the assumed offset of fp0
1171
        by 4 to bring it into (apparently) appropriate alignment with
1172
        reality.
1173
 
1174
Tue Jul 18 18:14:42 1989  Randy Smith  (randy at hobbes.ai.mit.edu)
1175
 
1176
        * Makefile: pinsn.o should depend on opcode.h
1177
 
1178
        * m68k-opcode.h: Moved fmovemx with register lists to before other
1179
        fmovemx.

1182
 
1183
        * Makefile, m*.h: Only #define vprintf (to _doprnt or printf,
1184
        depends on the system) if the library lacks it (controlled by
1185
        LACK_VPRINTF_DEFINE in makefile).  Unpleasant, but necessary to
1186
        make this work with the GNU C library.
1187

1208
 
1209
        * infcmd.c (registers_info): Clean up display to look good with long
1210
        register names, to say "register" instead of "reg", and to put the
1211
        "relative to selected stack frame" bit at the top.
1212
 
1213
Fri Jul 14 18:23:09 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)

1240
 
1241

1269
        isn't integral.
1270
 
1271
        * Makefile: Added removal of core and gdb[0-9] files to clean
1272
        target.
1273

1326
        enable_breakpoint, disable_breakpoint): #ifdef'd out changes
1327
        below; they produce unwanted output in gdb mode in gnu-emacs.
1328
 
1329
        * gdb.texinfo: Spelled.  Also removed index references from
1330
        command editing section; the relevance/volume ratio was too low.

1332
 
1333
        * ns32k-opcode.h, ns32k-pinsn.c: Backed out changes of June 24th;

1339
        i386_follow_jump.
1340
        * values.c (unpack_double): Added a return (double)0 at the end to

1343
        * printcmd.c (containing_function_bounds, asdump_command): Created
1344
        to dump the assembly code of a function (support for xgdb and a

1347
        * gdb.texinfo [Memory]: Added documentation for the asdump
1348

1353
        prointout to include pc value.
1354
        * stack.c: Added a new variable; "frame_changed" to indicate when
1355
        a frame has been changed so that gdb can print out a frame change
1356
        message when the frame only changes implicitly.
1357
        (print_frame_info): Check the new variable in determining when to
1358
        print out a new message and set it to zero when done.
1359
        (up_command): Increment it.
1360
        (down_command): Decrement it.
1361
 
1362
        * m68k-pinsn.c (print_insn_arg [lL]): Modified cases for register
1363
        lists to reset the point to point to after the word from which the
1364
        list is grabbed *if* that would cause point to point farther than
1365
        it currently is.

1730
        convention.

1766
 
1767
        * main.c (symbol_completion_function): Always complete on result
1768
        command list, even if exact match found.  If it's really an exact

1770
        it'll get the right result.
1771

1782
        that one shouldn't insert the breakpoints on the next step for

        returning from a sigtramp and forcing at least one move forward.
1784
 
1785
        * infrun.c (wait_for_inferior): Change test for nexting into a
1786
        function to check for current stack pointer inner than previous

1807
        [Attach]: Cleaned up.

        * dbxread.c (process_one_symbol, read_dbx_symtab): Changed N_FN to
1851

2026
        to checking frameless invocation first before checking frame

2248
        N_ECOMM.

        * stack.c (print_frame_info): Used instead of hand coding for same
2368
        thing.
2369
 
2370
        * dbxread.c (psymtab_to_symtab): No longer patch readin pst's out
2371
        of the partial_symtab_list; need them there for some checks.
2372
        * blockframe.c (block_for_pc), source.c (select_source_symtab),
2373
        symtab.c (lookup_symbol, find_pc_symtab, list_symbols): Made extra
2374
        sure not to call psymtab_to_symtab with ->readin == 1, since these
2375
        psymtab now stay on the list.
2376
        * symtab.c (sources_info): Now distinguishes between psymtabs with
2377
        readin set and those with it not set.
2378
 
2379
        * symtab.c (lookup_symtab): Added check through partial symtabs
2380
        for name with .c appended.
2381
 
2382
        * source.c (select_source_symtab): Changed semantics a little so
2383
        that the argument means something.
2384
        * source.c (list_command), symtab.c (decode_line_1): Changed call
2385
        to select_source_symtab to match new conventions.
2386
 
2387
        * dbxread.c (add_file_command): This command no longer selects a
2388
        symbol table to list from.
2389
 
2390
        * infrun.c (wait_for_inferior): Only call find_pc_function (to
2391
        find out if we have debugging symbols for a function and hence if
2392
        we should step over or into it) if we are doing a "step".

2395
 
2396
        * main.c (command_line_input): Added a local buffer and only
2397
        copied information into the global main.c buffer when it is
2398
        appropriate for it to be saved (and repeated).
2399
        (dont_repeat): Only nail line when we are reading from stdin
2400
        (otherwise null lines won't repeat and what's in line needs to be
2401
        saved).
2402
        (read_command_lines): Fixed typo; you don't what to repeat when
2403
        reading command lines from the input stream unless it's standard
2404
        input.
2405
 
2406
        John Gilmore's (gnu@toad.com) mods for USG gdb:
2407
        * inflow.c: Removed inclusion of sys/user.h; no longer necessary.
2408
        (, terminal_init_inferior, terminal_inferior, terminal_ours_1,
2409
        term_status_command, _initialize_inflow) Seperated out declaration
2410
        and usage of terminal mode structures based on the existence of
2411
        the individual ioctls.
2412
        * utils.c (request_quit): Restore signal handler under USG.  If
2413
        running under USG initialize sys_siglist at run time (too much
2414
        variation between systems).
2415

2418
        John Gilmore's (gnu@toad.com) mods for USG gdb:
2419
        * default-dep.c: Moved include of sys/user.h to after include of
2420
        a.out.h.
2421
        (store_inferior_registers): Fixed error message.
2422
        (core_file_command): Improved error messages from reading in of
2423
        u area in core file.  Changed calculation of offset of registers
2424
        to account for some machines putting it in as an offset rather
2425
        than an absolute address.  Changed error messages for reading of
2426
        registers from core file.
2427
 
2428
        * coffread.c (read_file_hdr): Added final check for BADMAG macro
2429
        to use if couldn't recognize magic number.
2430
        * Makefile: Added explicit directions for alloca addition.
2431
        Included alloca.c in list of possible library files. Cleaned up
2432
        possible library usage.  Included additional information on gcc
2433
        and include files.
2434
 
2435
        * source.c, remote.c, inflow.c, dbxread.c, core.c, coffread.c:
2436
        Changed include of sys/fcntl.h to an include of fcntl.h (as per
2437
        posix; presumably this will break fewer machines.  I hopw).
2438
        * README: Added a pointer to comments at top of Makefile.
2439
        * Makefile: Added a comment about machines which need fcntl.h in
2440
        sys.

2443
 
2444
        * valprint.c (set_prettyprint_command, set_unionprint_command,
2445
        format_info): Created.
2446
        (_initialize_valprint): Added to lists of commands.
2447
 
2448
        * gdb.texinfo [Backtrace]: Added a section describing the format
2449
        if symbols have not yet been read in.
2450
 
2451
        * valprint.c (val_print): Added code to prettyprint structures if
2452
        "prettyprint" is set and only to print unions below the top level
2453
        if "unionprint" is set.
2454
 
2455
        * infcmd.c (registers_info), valprint.c (value_print, val_print):
2456
        Added argument to call to val_print indicating deptch of recursion.
2457
 
2458
        * symtab.[ch] (find_pc_psymbol): Created; finds static function
2459
        psymbol with value nearest to but under value passed.
2460
        * stack.c (print_frame_info): Used above to make sure I have best
2461
        fit to pc value.
2462
 
2463
        * symseg.h (struct partial_symbol): Added value field.
2464
        * dbxread.c (read_dbx_symtab): Set value field for partial symbols
2465
        saved (so that we can lookup static symbols).
2466
 
2467
        * symtab.[ch] (find_pc_symtab): Changed to external.
2468
        * stack.c (select_frame): Call above to make sure that symbols for
2469
        a selected frame is readin.
2470
 
2471
Mon Apr  3 12:48:16 1989  Randall Smith  (randy at plantaris.ai.mit.edu)
2472
 
2473
        * stack.c (print_frame_info): Modified to only print out full
2474
        stack frame info on symbols whose tables have been read in.
2475
        * symtab.c, symtab.h (find_pc_psymtab): Made function external;
2476
        above needed it.
2477
 
2478
        * main.c (,set_verbose_command, initialize_main): Created a
2479
        variable "info_verbose" which says to talk it up in various and
2480
        sundry places.  Added command to set this variable.
2481
        * gdb.texinfo (GDB Output): Added documentation on "set verbose"
2482
        and changed the name of the "Screen Output" section to "GDB
2483
        Output".
2484
        * dbxread.c (psymtab_to_symtab): Added information message about
2485
        symbol readin.  Conditionalized on above.
2486
 
2487
        * dbxread.c (define_symbol): Made an "i" constant be of class
2488
        LOC_CONST and an "r" constant be of class LOC_CONST_BYTES.
2489
 
2490
        * README: Made a note about modifications which may be necessary
2491
        to the manual for this version of gdb.
2492
 
2493
        * blockframe.c (get_prev_frame_info): Now we get saved address and
2494
        check for validity before we check for leafism.  This means that
2495
        we will catch the fact that we are in start, but we will miss any
2496
        fns that start calls without an fp.  This should be fine.
2497
 
2498
        * m-*.h (FRAME_CHAIN): Modified to return 0 if we are in start.
2499
        This is usually a test for within the first object file.
2500
        * m-sparc.h (FRAME_CHAIN): The test here is simply if the fp saved
2501
        off the the start sp is 0.
2502
 
2503
        * blockframe.c (get_prev_frame_info): Removed check to see if we
2504
        were in start.  Screws up sparc.
2505
 
2506
        * m-sparc.h (FRAME_FIND_SAVED_REGISTERS): Changed test for dummy
2507
        frame to not need frame to be innermost.
2508
 
2509
        * gdb.texinfo: Added section on frameless invocations of functions
2510
        and when gdb can and can't deal with this.
2511
 
2512
        * stack.c (frame_info): Disallowed call if no inferior or core
2513
        file; fails gracefully if truely bad stack specfication has been
2514
        given (ie. parse_frame_specification returns 0).
2515
 
2516
Fri Mar 31 13:59:33 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
2517
 
2518
        * infrun.c (normal_stop): Changed references to "unset-env" to
2519
        "delete env".
2520
 
2521
        * infcmd.c (_initialize_infcmd): Change reference to set-args in
2522
        help run to "set args".
2523
 
2524
        * remote.c (getpkt): Allow immediate quit when reading from
2525
        device; it could be hung.
2526
 
2527
        * coffread.c (process_coff_symbol): Modify handling of REG
2528
        parameter symbols.
2529
 
2530
Thu Mar 30 15:27:23 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
2531
 
2532
        * dbxread.c (symbol_file_command): Use malloc to allocate the
2533
        space for the string table in symbol_file_command (and setup a
2534
        cleanup for this).  This allows a more graceful error failure if
2535
        there isn't any memory availible (and probably allows more memory
2536
        to be avail, depending on the machine).
2537
 
2538
        Additional mods for handling GNU C++ (from Tiemann):
2539
        * dbxread.c (read_type): Added case for '#' type (method type, I
2540
        believe).
2541
        (read_struct_type): If type code is undefined, make the main
2542
        variant for the type be itself.  Allow recognition of bad format
2543
        in reading of structure fields.
2544
        * eval.c (evaluate_subexp): Modify evaluation of a member of a
2545
        structure and pointer to same to make sure that the syntax is
2546
        being used correctly and that the member is being accessed correctly.
2547
        * symseg.h: Added TYPE_CODE_METHOD to enum type_code.  Add a
2548
        pointer to an array of argument types to the type structure.
2549
        * symtab.c (lookout_method_type, smash_to_method_type): Created.
2550
        * symtab.h (TYPE_ARG_TYPES): Created.
2551
        * valops.c (call_function): Modified handling of methods to be the
2552
        same as handling of functions; no longer check for members.
2553
        * valprint.c (val_print, type_print_varspec_{prefix,suffix},
2554
        type_print_base): Added code to print method args correctly.
2555
        * values.c (value_virtual_fn_field): Modify access to virtual
2556
        function table.

2559
 
2560
        * findvar.c: Special cases for REGISTER_WINDOWS: 1) Return 0 if we
2561
        are the innermost frame, and 2) return the next frame in's value
2562
        if the SP is being looked for.
2563
 
2564
        * blockframe.c (get_next_frame): Created; returns the next (inner)
2565
        frame of the called frame.
2566
        * frame.h: Extern delcaration for above.
2567
 
2568
        * main.c (command_line_input): Stick null at end before doing
2569
        history expansion.
2570

2573
        * dbxread.c (read_dbx_symtab): Added namestring assignment to
2574
        N_DATA/BSS/ABS case.  Sigh.

2582
        * symtab.c (make_symbol_completion_list): Completely rewrote to
2583
        never call psymtab_to_symtab, to do a correct search (no
2584
        duplicates) through the visible symbols, and to include structure
2585
        and union fields in the things that it can match.
2586

2588
 
2589
        * dbxread.c (dbx_create_type): Created; allocates and inits space
2590
        for a type without putting it on the type vector lists.
2591
        (dbx_alloc_type): Uses above.
2592
 
2593
        * Makefile: xgdb.o now produced by default rules for .o.c.

2607
        frame to null when inferior dies.
2608
 
2609
        * dbxread.c (symbol_file_command): free and zero symfile when
2610
        discarding symbols.
2611
 
2612
        * core.c (xfer_core_file): Extended and cleaned up logic in
2613
        interpeting memory address.

2624
 
2625
        * stack.c (frame_info): Printed out value of "saved" sp seperately
2626
        to call attention to the fact that it isn't stored in memory
2627
        anywhere; the actual previous frames address is printed.
2628
 
2629
        * m-sparc.h (FRAME_FIND_SAVED_REGS): Set address of sp saved in
2630
        frame to value of fp (rather than value of sp in current frame).
2631
 
2632

2633
        modifier.

2643
 
2644
        * remote.c (remote_open): Cast return from signal to (void (*)) to
2645
        avoid problems on machines where the return type of signal is (int
2646
        (*)).
2647
 
2648
        * Makefile: Removed deletion of version control from it (users
2649
        will need it for their changes).
2650
 
2651
Thu Mar  2 15:32:21 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
2652

2656
 
2657
        * xgdb.c (do_command): Copied command before calling execute
2658
        command (so that execute_command wouldn't write into text space).
2659
 
2660
        * copying.awk: Created (will produce copying.c as output when
2661
        given COPYING as input).
2662

2663
        * main.c: Took out info_warranty and info_copying.
2664

2669
        the source and sink.
2670
        (print_prompt): Added fflush (stdout).
2671
 
2672
        * Makefile: Added -lXmu to the compilation line for xgdb.  Left
2673
        the old one there incase people still had R2.
2674
 
2675

        * remote.c (remote_timer): Created.
2693
        (remote_open, readchar): Setup to timeout reads if they take
2694
        longer than "timeout".  This allows one to debug how long such
2695
        things take.
2696
        (putpkt): Modified to print a debugging message (if such things
2697
        are enabled) each time it resends a packet.
2698
        (getpkt): Modified to make the variable CSUM unsigned and read it
2699
        CSUM with an & 0xff (presumably to deal with poor sign extension
2700
        on some machines).  Also made c1 and c2 unsigned.
2701
        (remote_wait): Changed buffer to unsigned status.
2702
        (remote_store_registers, remote_write_bytes): Puts a null byte at
2703
        the end of the control string.
2704
 
2705
        * infcmd.c (attach_command, detach_command, _initialize_infcmd):
2706
        Made attach_command and detach_command always availible, but
2707
        modified them to only allow device file attaches if ATTACH_DETACH
2708
        is not defined.
2709
 
2710
        * gdb.texinfo: Added cross reference from attach command to remote
2711
        debugging.

2714
 
2715
        * remote.c (remote_close): Created to close the remote connection
2716
        and set the remote_debugging flag to 0.
2717
        * infcmd.c (detach_command): Now calls the above when appropriate.
2718
 
2719
        * gdb.texinfo: Removed references to the ``Distribution'' section
2720
        in the copyright.
2721
 
2722
        * main.c, utils.c (ISATTY): Created default defintions of this
2723
        macro which use isatty and fileno.
2724
        * utils.c (fprintf_filtered, print_spaces_filtered), main.c
2725
        (command_loop, command_line_input): Used this macro.
2726
        * m-news.h: Created a definition to override this one.
2727
 
2728
        * utils.c (fprintf_filtered): Made line_size static (clueless).
2729
 
2730
        * utils.c (fprintf_filtered): Changed max length of line printed
2731
        to be 255 chars or twice the format length.
2732
 
2733
        * symmetry-dep.c, m-symmetry: Fixed typo (^L ==> ).
2734
 
2735
        * printcmd.c (do_examine): Fixed typo (\n ==> \t).

        Contributed by Jay Vosburgh (jay@mentor.cc.purdue.edu)
2740
        * m-symmetry.h, symmetry-dep.c: Created.
2741
        * Makefile: Added above in appropriate lists.
2742
        * config.gdb: Added "symmetry" target.
2743
 
2744
        * utils.c (prompt_for_continue): Zero'd chars_printed also.
2745
 
2746
        * utils.c (fprintf_filtered): Call prompt for continue instead of
2747
        doing it yourself.
2748
 
2749
        * dbxread.c (read_dbx_symtab): Added code to conditionalize what
2750
        symbol type holds to "x.o" or "-lx" symbol that indicates the
2751
        beginning of a new file.
2752

2754
 
2755
        * gdb.texinfo: Deleted @ignore block at end of file.
2756
 
2757
        * findvar.c, stack.c: Changed comments that refered to "frame
2758
        address" to "frame id".
2759
 
2760
        * findvar.c (locate_var_value): Modified so that taking the
2761
        address of an array generates an object whose type is a pointer to
2762
        the elements of the array.

2765
 
2766
        * gdb.texinfo: Removed reference to "!" as a shell escape
2767
        character.  Added a section on controling screen output
2768
        (pagination); changing "Input" section to "User Interface"
2769
        section.  Changed many inappropriate subsubsection nodes into
2770
        subsections nodes (in the readline and history expansion
2771
        sections).
2772

2774
 
2775
        * utils.c (set_screensize_command): Created.
2776
        (_initialize_utils): Added above to setlist.
2777
 
2778
        * main.c (main): Added check to see if ~/.gdbinit and .gdbinit
2779
        were the same file; only one gets read if so.  Had to include
2780
        sys/stat.h for this.
2781
 
2782
        * valprint.c (type_print_base): Changed calls to print_spaces to
2783
        print_spaces_filtered.
2784
 
2785
        * main.c (command_line_input): Chaned test for command line
2786
        editing to check for stdin and isatty.
2787
 
2788
        * main.c (command_loop): Call reinitialize_more_filter before each
2789
        command (if reading from stdin and it's a tty).
2790
        utils.c (initialize_more_filter): Changed name to
2791
        reinitialize_more_filter; killed arguments.
2792
        utils.c (_initialize_utils): Created; initialized lines_per_page
2793
        and chars_per_line here.
2794
 
2795
        * utils.c (fprintf_filtered): Removed printing of "\\\n" after
2796
        printing linesize - 1 chars; assume that the screen display will
2797
        take care of that.  Still watching that overflow.
2798
 
2799
        * main.c: Created the global variables linesize and pagesize to
2800
        describe the number of chars per line and lines per page.

        type_print_derivation_info, type_print_varspec_suffix,
2808
        type_print_base), breakpoint.c (breakpoints_info, breakpoint_1),
2809
        values.c (history_info), main.c (editing_info, warranty_info,

2812
        (backtrace_command, print_frame_info), symtab.c (list_symbols,
2813
        output_source_filename), command.c (help_cmd, help_list,
2814
        help_command_list): Replaced calls to printf, fprintf, and putc
2815
        with calls to [f]printf_filtered to handle more processing.
2816
        Killed local more emulations where I noticed them.

2818
Wed Feb 15 15:27:36 1989  Randall Smith  (randy at gluteus.ai.mit.edu)
2819
 
2820
        * defs.h, utils.c (initialize_more_filter, fprintf_filtered,
2821
        printf_filtered): Created a printf that will also act as a more
2822
        filter, prompting the user for a  whenever the page length
2823
        is overflowed.
2824
 
2825
        * symtab.c (list_symbols): Elminated some code inside of an #if 0.
2826
 
2827
Tue Feb 14 11:11:24 1989  Randall Smith  (randy at gluteus.ai.mit.edu)
2828
 
2829
        * Makefile: Turned off backup versions for this file; it changes
2830
        too often.
2831
 
2832
        * command.c (lookup_cmd, _initialize_command): Changed '!' so that
2833
        it was no longer a shell escape.  "sh" must be used.
2834
 
2835
        * main.c (command_line_input, set_history_expansion,
2836
        initialize_main): Turned history expansion on, made it the
2837
        default, and only execute it if the first character in the line is
2838
        a '!'.
2839
 
2840
        * version.c, gdb.texinfo: Moved version to 3.2 (as usual, jumping
2841
        the gun some time before release).
2842
 
2843
        * gdb.texinfo: Added sections (adapted from Brian's notes) on
2844
        command line editing and history expansion.
2845
 
2846
        * main.c (set_command_editing, initialize_main): Modified name to
2847
        set_editing and modified command to "set editing".
2848
 
2849
        * Makefile: Put in dependencies for READLINEOBJS.
2850
 
2851
        * main.c (history_info, command_info): Combined into new command
2852
        info; deleted history_info.
2853
        (initialize_main): Deleted "info history" command; it was
2854
        interfering with the value history.
2855
 
2856
        * coffread.c (enter_linenos): Modified to do bit copy instead of
2857
        pointer dereference, since the clipper machine can't handle having
2858
        longs on short boundaries.
2859
        (read_file_hdr): Added code to get number of syms for clipper.
2860
 
2861
        * stack.c (return_command): Fixed method for checking when all of
2862
        the necessary frames had been popped.
2863
 
2864
        * dbxread.c (read_dbx_symtab (ADD_PSYMBOL_TO_LIST)): Fixed typo in
2865
        allocation length.
2866
 
2867
Mon Feb 13 10:03:27 1989  Randall Smith  (randy at gluteus.ai.mit.edu)
2868
 
2869
        * dbxread.c (read_dbx_symtab): Split assignment to namestring into
2870
        several different assignments (so that it wouldn't be done except
2871
        when it had to be).  Shortened switches and duplicated code to
2872
        produce the lowest possible execution time.  Commented (at top of
2873
        switch) which code I duplicated.
2874
 
2875
        * dbxread.c (read_dbx_symtab): Modified which variables were
2876
        register and deleted several variables which weren't used.  Also
2877
        eliminated 'F' choice from subswitch, broke out strcmp's, reversed
2878
        compare on line 1986, and elminated test for !namestring[0]; it is
2879
        caught by following test for null index of ':'.

2886
 
2887
        * symtab.c (find_pc_psymtab): Created; checks all psymtab's till
2888
        it finds pc.
2889
        (find_pc_symtab): Used; fatal error if psymtab found is readin
2890
        (should have been caught in symtab loop).
2891
        (lookup_symbol): Added check before scan through partial symtab
2892
        list for symbol name to be on the misc function vector (only if in
2893
        VAR_NAMESPACE).  Also made sure that psymtab's weren't fooled with
2894
        if they had already been read in.
2895
        (list_symbols): Checked through misc_function_vector for matching
2896
        names if we were looking for functions.
2897
        (make_symbol_completion_list): Checked through
2898
        misc_function_vector for matching names.
2899
        * dbxread.c (read_dbx_symtab): Don't bother to do processing on
2900
        global function types; this will be taken care of by the
2901
        misc_function hack.
2902
 
2903
        * symtab.h: Modified comment on misc_function structure.
2904

        * symseg.h, dbxread.c (read_dbx_symtab, init_psymbol_list,
2908
        start_psymtab, end_psymtab), coffread.c (_initialize_coff),
2909
        symtab.c (lookup_partial_symbol, list_symbols,
2910
        make_symbol_completion_list): Changed separate variables for
2911
        description of partial symbol allocation into a specific kind of
2912
        structure.
2913
 
2914
        (read_dbx_symtab, process_symbol_for_psymtab): Moved most of
2915
        process_symbol_for_psymtab up into read_dbx_symtab, moved a couple
2916
        of symbol types down to the ingore section, streamlined (I hope)
2917
        code some, modularized access to psymbol lists.

2922
        newlines as indications to repeat the last line.
2923
 
2924
        * symtab.c (_initialize_symtab): Changed size of builtin_type_void
2925
        to be 1 for compatibility with gcc.
2926
 
2927
        * main.c (initialize_main): Made history_expansion the default
2928
        when gdb is compiled with HISTORY_EXPANSION.
2929
 
2930
        * readline.c, readline.h, history.c, history.h, general.h,
2931
        emacs_keymap.c, vi_keymap.c, keymaps.c, funmap.c: Made all of
2932
        these links to /gp/gnu/bash/* to keep them updated.
2933
        * main.c (initialize_main): Made default be command editing on.

2945
        accesible command lists.
2946
        (parse_binary_operation): Created to parse a on/1/yes vs. off/0/no
2947
        spec.
2948
        (set_command_edit, set_history, set_history_expansion,
2949
        set_history_write, set_history_size, set_history_filename,
2950
        command_info, history_info): Created to allow users to control
2951
        various aspects of command line editing.
2952
 
2953
        * main.c (symbol_creation_function): Created.
2954
        (command_line_input, initialize_main): Added rest of stuff
2955
        necessary for calling bfox' command editing routines under
2956
        run-time control.
2957
        * Makefile: Included readline and history source files for command
2958

2965
        command_editing_p, history_expansion_p, history_size,
2966
        write_history_p, history_filename.  Initialized them to default
2967
        values in initialize_main.
2968
 
2969
        * infcmd.c (registers_info), infrun.c (signals_info),
2970
        * main.c (gdb_read_line): Changed name to command_line_input.
2971
        (readline): Changed name to gdb_readline; added second argument

2986
        * main.c (gdb_read_line, readline): Added function readline and
2987
        converted gdb_read_line to use it.  This was a conversion to the
2988
        line at a time style of input, in preparation for full command
2989
        editing.
2990
 
2991

2996
        * config.gdb, sun3-dep.c: Brought these into accord with the
2997
        actual sun2 status (no floating point period; sun3-dep.c unless
2998
        has os > 3.0).
2999
        * m-sun2os2.h: Deleted; not needed.
3000
 
3001
        * config.gdb: Added a couple of aliases for machines in the
3002
        script.
3003
 
3004
        * infrun.c: Added inclusion of aouthdr.h inside of #ifdef UMAX
3005
        because ptrace needs to know about the a.out header.

3007
        * Makefile: Made dep.o depend on dep.c and config.status only.
3008
 
3009

3013
        if they wish.
3014

3020
 
3021
        * *-dep.c: Deleted definition of COFF_FORMAT if AOUTHDR was
3022
        defined since 1) We *may* (recent mail message) want to define
3023
        AOUTHDR under a basically BSD system, and 2) AOUTHDR is sometimes
3024
        a typedef in coff encapsulation setups.  Also removed #define's of
3025
        AOUTHDR if AOUTHDR is already defined (inside of coff format).
3026
        * core.c, dbxread.c: Removed #define's of AOUTHDR if AOUTHDR is
3027
        already defined (inside of coff format).

3030
 
3031
        * GDB 3.1 released.
3032
 
3033
        * values.c (modify_field): Changed test for endianness to assign
3034
        to integer and reference character (so that all bits would be
3035
        defined).
3036
 
3037
Mon Jan 30 11:41:21 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3038
 
3039
        * news-dep.c: Deleted inclusion of fcntl.h; just duplicates stuff
3040
        found in sys/file.h.
3041
 
3042
        * i386-dep.c: Included default definition of N_SET_MAGIC for
3043
        COFF_FORMAT.
3044
 
3045
        * config.gdb: Added checks for several different operating
3046
        systems.
3047
 
3048
        * coffread.c (read_struct_type): Put in a flag variable so that
3049
        one could tell when you got to the end of a structure.
3050
 
3051
        * sun3-dep.c (core_file_command): Changed #ifdef based on SUNOS4
3052
        to ifdef based on FPU.
3053
 
3054
        * infrun.c (restore_inferior_status): Changed error message to
3055
        "unable to restore previously selected frame".
3056
 
3057
        * dbxread.c (read_dbx_symtab): Used intermediate variable in error
3058
        message reporting a bad symbol type.  (scan_file_globals,
3059
        read_ofile_symtab, read_addl_syms): Data type of "type" changed to
3060
        unsigned char (which is what it is).
3061
        * i386-dep.c: Removed define of COFF_FORMAT if AOUTHDR is defined.
3062
        Removed define of a_magic to magic (taken care of by N_MAGIC).
3063
        (core_file_command): Zero'd core_aouthdr instead of setting magic
3064
        to zero.
3065
        * i386-pinsn.c: Changed jcxz == jCcxz in jump table.
3066
        (putop): Added a case for 'C'.
3067
        (OP_J): Added code to handle possible masking of PC value on
3068
        certain kinds of data.
3069
        m-i386gas.h: Moved COFF_ENCAPSULATE to before inclusion of
3070
        m-i386.h and defined NAMES_HAVE_UNDERSCORE.
3071
 
3072
        * coffread.c (unrecrod_misc_function, read_coff_symtab): Added
3073
        symbol number on which error occured to error output.

3076
 
3077
        * Makefile: Removed init.c in make clean.  Removed it without -f
3078
        and with leading - in make ?gdb.
3079

Thu Jan 26 15:08:03 1989  Randall Smith  (randy at gluteus.ai.mit.edu)
3081
 
3082
        Changes to get it to work on gould NP1.
3083
        * dbxread.c (read_dbx_symtab): Included cases for N_NBDATA and
3084
        N_NBBSS.
3085
        (psymtab_to_symtab): Changed declaration of hdr to
3086
        DECLARE_FILE_HEADERS.  Changed access to use STRING_TABLE_SIZE and

        * gld-pinsn.c (findframe): Added declaration of framechain() as
3089
        FRAME_ADDR.
3090
 
3091
        * coffread.c (read_coff_symtab): Avoided treating typedefs as
3092
        external symbol definitions.
3093
 
3094
Wed Jan 25 14:45:43 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3095
 
3096
        * Makefile: Removed reference to alloca.c.  If they need it, they
3097
        can pull alloca.o from the gnu-emacs directory.
3098
 
3099
        * version.c, gdb.texinfo: Updated version to 3.1 (jumping the gun
3100
        a bit so that I won't forget when I release).
3101
 
3102
        * m-sun2.h, m-sun2os2.h, m-sun3os4.h, config.gdb: Modified code so
3103
        that default includes new sun core, ptrace, and attach-detach.
3104
        Added defaults for sun 2 os 2.
3105
 
3106
        Modifications to reset stack limit back to what it used to be just
3107
        before exec.  All mods inside of #ifdef SET_STACK_LIMIT_HUGE.
3108
        * main.c: Added global variable original_stack_limit.
3109
        (main): Set original_stack_limit to original stack limit.
3110
        * inflow.c: Added inclusion of necessary files and external
3111
        reference to original_stack_limit.
3112
        (create_inferior): Reset stack limit to original_stack_limit.
3113
 
3114
        * dbxread.c (read_dbx_symtab): Killed PROFILE_SYMBOLS ifdef.
3115
 
3116
        * sparc-dep.c (isabranch): Multiplied offset by 4 before adding it
3117
        to addr to get target.
3118
 
3119
        * Makefile: Added definition of SHELL to Makefile.
3120
 
3121
        * m-sun2os4.h: Added code to define NEW_SUN_PTRACE, NEW_SUN_CORE,
3122
        and ATTACH_DETACH.
3123
        * sun3-dep.c: Added code to avoid fp regs if we are on a sun2.
3124
 
3125
Tue Jan 24 17:59:14 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3126
 
3127
        * dbxread.c (read_array_type): Added function.
3128
        (read_type): Added call to above instead of inline code.
3129
 
3130
        * Makefile: Added ${GNU_MALLOC} to the list of dependencies for
3131
        the executables.
3132
 
3133
Mon Jan 23 15:08:51 1989  Randall Smith  (randy at plantaris.ai.mit.edu)
3134
 
3135
        * gdb.texinfo: Added paragraph to summary describing languages
3136
        with which gdb can be run.  Also added descriptions of the
3137
        "info-methods" and "add-file" commands.
3138
 
3139
        * symseg.h: Commented a range type as having TYPE_TARGET_TYPE
3140
        pointing at the containing type for the range (often int).
3141
        * dbxread.c (read_range_type): Added code to do actual range types
3142
        if they are defined.  Assumed that the length of a range type is
3143
        the length of the target type; this is a lie, but will do until
3144
        somebody gets back to me as to what these silly dbx symbols mean.
3145
 
3146
        * dbxread.c (read_range_type): Added code to be more picky about
3147
        recognizing builtins as range types, to treat types defined as
3148
        subranges of themselves to be subranges of int, and to recognize
3149
        the char type idiom from dbx as a special case.
3150
 
3151
Sun Jan 22 01:00:13 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3152
 
3153
        * m-vax.h: Removed definition of FUNCTION_HAS_FRAME_POINTER.
3154
        * blockframe.c (get_prev_frame_info): Removed default definition
3155
        and use of above.  Instead conditionalized checking for leaf nodes
3156
        on FUNCTION_START_OFFSET (see comment in code).
3157
 
3158
Sat Jan 21 16:59:19 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3159
 
3160
        * dbxread.c (read_range_type): Fixed assumption that integer was
3161
        always type 1.
3162
 
3163
        * gdb.texinfo: Fixed spelling mistake and added a note in the
3164
        running section making it clear that users may invoke subroutines
3165
        directly from gdb.
3166
 
3167
        * blockframe.c: Setup a default definition for the macro
3168
        FUNCTION_HAS_FRAME_POINTER.
3169
        (get_prev_frame_info): Used this macro instead of checking
3170
        SKIP_PROLOGUE directly.
3171
        * m-vax.h: Overroad definition; all functions on the vax have
3172
        frame pointers.
3173
 
3174
Fri Jan 20 12:25:35 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3175
 
3176
        * core.c: Added default definition of N_MAGIC for COFF_FORMAT.
3177
 
3178
        * xgdb.c: Installed a fix to keep the thing from dying when there
3179
        isn't any frame selected.
3180
 
3181
        * core.c: Made a change for the UMAX system; needs a different
3182
        file included if using that core format.
3183
 
3184
        * Makefile: Deleted duplicate obstack.h in dbxread.c dependency.
3185
 
3186
        * munch: Modified (much simpler) to cover (I hope) all cases.
3187
 
3188
        * utils.c (save_cleanups, restore_cleanups): Added functions to
3189
        allow you to push and pop the chain of cleanups to be done.
3190
        * defs.h: Declared the new functions.
3191
        * main.c (catch_errors): Made sure that the only cleanups which
3192
        would be done were the ones put on the chain *after* the current
3193
        location.
3194
 
3195
        * m-*.h (FRAME_CHAIN_VALID): Removed check on pc in the current
3196
        frame being valid.
3197
        * blockframe.c (get_prev_frame_info): Made the assumption that if
3198
        a frame's pc value was within the first object file (presumed to
3199
        be /lib/crt0.o), that we shouldn't go any higher.
3200
 
3201
        * infrun.c (wait_for_inferior): Do *not* execute check for stop pc
3202
        at step_resume_break if we are proceeding over a breakpoint (ie.
3203
        if trap_expected != 0).
3204
 
3205
        * Makefile: Added -g to LDFLAGS.
3206
 
3207
        * m-news.h (POP_FRAME) Fixed typo.
3208
 
3209
        * printcmd.c (print_frame_args): Modified to print out register
3210
        params in order by .stabs entry, not by register number.
3211
 
3212
        * sparc-opcode.h: Changed declaration of (struct
3213
        arith_imm_fmt).simm to be signed (as per architecture manual).
3214
        * sparc-pinsn.c (fprint_addr1, print_insn): Forced a cast to an
3215
        int, so that we really would get signed behaivior (default for sun
3216
        cc is unsigned).
3217
 
3218
        * i386-dep.c (i386_get_frame_setup): Replace function with new
3219
        function provided by pace to fix bug in recognizing prologue.
3220
 
3221
Thu Jan 19 11:01:22 1989  Randall Smith  (randy at plantaris.ai.mit.edu)
3222
 
3223
        * infcmd.c (run_command): Changed error message to "Program not
3224
        restarted."
3225
 
3226
        * value.h: Changed "frame" field in value structure to be a
3227
        FRAME_ADDR (actually CORE_ADDR) so that it could survive across
3228
        calls.
3229
 
3230
        * m-sun.h (FRAME_FIND_SAVED_REGS): Fixed a typo.
3231
 
3232
        * value.h: Added lval: "lval_reg_frame_relative" to indicate a
3233
        register that must be interpeted relative to a frame.  Added
3234
        single entry to value structure: "frame", used to indicate which
3235
        frame a relative regnum is relative to.
3236
        * findvar.c (value_from_register): Modified to correctly setup
3237
        these fields when needed.  Deleted section to fiddle with last
3238
        register copied on little endian machine; multi register
3239
        structures will always occupy an integral number of registers.
3240
        (find_saved_register): Made extern.
3241
        * values.c (allocate_value, allocate_repeat_value): Zero frame
3242
        field on creation.
3243
        * valops.c (value_assign): Added case for lval_reg_frame_relative;
3244
        copy value out, modify it, and copy it back.  Desclared
3245
        find_saved_register as being external.
3246
        * value.h: Removed addition of kludgy structure; thoroughly
3247
        commented file.
3248
        * values.c (free_value, free_all_values, clear_value_history,
3249
        set_internalvar, clear_internavars): Killed free_value.
3250
 
3251

3252
 
3253
        * value.h: Deleted struct partial_storage; left over from
3254
        yesterday.
3255
 
3256
        * findvar.c (value_from_register): Added code to create a value of
3257
        type lval_reg_partsaved if a value is in seperate registers and
3258
        saved in different places.
3259
 
3260
Tue Jan 17 13:50:18 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3261
 
3262
        * value.h: Added lval_reg_partsaved to enum lval_type and
3263
        commented enum lval_type.  Commented value structure.
3264
        Added "struct partial_register_saved" to value struct; added
3265
        macros to deal with structure to value.h.
3266
        * values.c (free_value): Created; special cases lval_reg_partsaved
3267
        (which has a pointer to an array which also needs to be free).
3268
        (free_all_values, clear_value_history, set_internalvar,
3269
        clear_internalvars): Modified to use free_values.
3270
 
3271
        * m-sunos4.h: Changed name to sun3os4.h.
3272
        * m-sun2os4.h, m-sun4os4.h: Created.
3273
        * config.gdb: Added configuration entries for each of the above.
3274
        * Makefile: Added into correct lists.
3275
 
3276
        * Makefile: Added dependencies on a.out.encap.h.  Made
3277
        a.out.encap.h dependent on a.out.gnu.h and dbxread.c dependent on
3278
        stab.gnu.h.
3279
 
3280
        * infrun.c, remote.c: Removed inclusion of any a.out.h files in
3281
        these files; they aren't needed.
3282
 
3283
        * README: Added comment about bug reporting and comment about
3284
        xgdb.
3285
 
3286
        * Makefile: Added note to HPUX dependent section warning about
3287
        problems if compiled with gcc and mentioning the need to add
3288
        -Ihp-include to CFLAGS if you compile on those systems.  Added a
3289
        note about needing the GNU nm with compilers *of gdb* that use the
3290
        coff encapsulate feature also.  * hp-include: Made symbolic link
3291
        over to /gp/gnu/binutils.
3292
 
3293
        * Makefile: Added TSOBS NTSOBS OBSTACK and REGEX to list of things
3294
        to delete in "make clean".  Also changed "squeakyclean" target as
3295
        "realclean".
3296
 
3297
        * findvar.c (value_from_register): Added assignment of VALUE_LVAL
3298
        to be lval_memory when that is appropriate (original code didn't
3299
        bother because it assumed that it was working with a pre lval
3300
        memoried value).
3301
 
3302
        * expread.y (yylex): Changed to only return type THIS if the
3303
        symbol "$this" is defined in some block superior or equal to the
3304
        current expression context block.
3305

3307
 
3308
        * m-*.h (FRAME_CHAIN_VALID): On machines which check the relation
3309
        of FRAME_SAVED_PC (thisframe) to first_object_file_end (all except
3310
        gould), make sure that the pc of the current frame also passes (in
3311
        case someone stops in _start).
3312
 
3313
        * findvar.c (value_of_register): Changed error message in case of
3314
        no inferior or core file.
3315
 
3316
        * infcmd.c (registers_info): Added a check for inferior or core
3317
        file; error message if not.
3318
 
3319
        * main.c (gdb_read_line): Modified to take prompt as argument and
3320
        output it to stdout.
3321
        * infcmd.c (registers_info, signals_info), main.c (command_loop,
3322
        read_command_lines, copying_info), symtab.c (decode_line_2,
3323
        output_source_filename, MORE, list_symbols): Changed calling
3324
        convention used to call gdb_read_line.
3325
 
3326
        * infcmd.c, infrun.c, main.c, symtab.c: Changed the name of the
3327
        function "read_line" to "gdb_read_line".
3328
        * breakpoint.c: Deleted external referenced to function
3329
        "read_line" (not needed by code).

3332
 
3333

3334
        (N_SET_MAGIC): Defined if not defined by include file.

        (core_file_command): Used N_SET_MAGIC instead of assignment to
3336
        a_magic.
3337
        (exec_file_command): Stuck in a HEADER_SEEK_FD.
3338

3353
 
3354
        * dbxread.c: Made which stab.h is included dependent on
3355
        COFF_ENCAPSULATE; either  or "gnu-stab.h".
3356
        * Makefile: Included gnu-stab.h in the list of files to include in
3357
        the distribution.

3361
        distribution files.
3362

3370
         inside of USG depends and deleted all SYSV ifdef's
3371
        (use USG instead).
3372
        * munch: Modified to accept any number of spaces between the T and
3373
        the symbol name.
3374
 
3375
        Pace's changes to gdb to work with COFF_ENCAPSULATE (robotussin):
3376
        * config.gdb: Added i386gas to targets.
3377
        * default-dep.c: Include a.out.encap.h if COFF_ENCAPSULATE.
3378
        (N_SET_MAGIC): Defined if not defined by include file.

3381
        * infrun.c, remote.c: Added an include of a.out.encap.h if
3382
        COFF_ENCAPSULATE defined.  This is commented out in these two
3383
        files, I presume because the definitions aren't used.
3384
        * m-i386gas.h: Created.
3385
        * dbxread.c: Included defintions for USG.

        * gdb.texinfo: Added the fact that the return value for a function
3402
        is printed if you use return.

3404
        * infrun.c (wait_for_inferior): Removed test in "Have we hit
3405
        step_resume_breakpoint" for sp values in proper orientation.  Was
3406
        in there for recursive calls in functions without frame pointers
3407
        and it was screwing up calls to alloca.
3408
 
3409
        * dbxread.c: Added #ifdef COFF_ENCAPSULATE to include
3410
        a.out.encap.h.
3411
        (symbol_file_command): Do HEADER_SEEK_FD when defined.
3412
        * dbxread.c, core.c: Deleted #ifdef ROBOTUSSIN stuff.

3414
        * a.out.encap.h: Created symlink to
3415
        /gp/gnu/binutils/a.out.encap.h.
3416
        * Makefile: Removed robotussin.h and included a.out.encap.h in
3417
        list of files.
3418
 
3419
        * valprint.c (val_print, print_scalar_formatted): Changed default
3420
        precision of printing float value; now 6 for a float and 16 for a
3421
        double.

3423
        * findvar.c (value_from_register): Added code to deal with the
3424
        case where a value is spread over several registers.  Still don't
3425
        deal with the case when some registers are saved in memory and
3426
        some aren't.

3431
        frameArgs.

3434
        equal to 0 or greater or equal to NSIG or a signal number is not
3435
        provided.
3436
 
3437
        * command.c (lookup_cmd): Modified to not convert command section
3438
        of command line to lower case in place (in case it isn't a
3439
        subcommand, but an argument to a command).
3440
 
3441
Fri Jan  6 17:57:34 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3442
 
3443
        * dbxread.c: Changed "text area" to "data area" in comments on

3456
        Also commented "enum noside".
3457
 
3458
        * Makefile: Changed invocations of munch to be "./munch".
3459
 
3460
        * gdb.texinfo: Updated to refer to current version of gdb with
3461
        January 1989 last update.
3462
 
3463
        * coffread.c (end_symtab): Zero context stack when finishing
3464
        lexical contexts.
3465
        (read_coff_symtab): error if context stack 0 in ".ef" else case.
3466
 
3467
        * m-*.h (FRAME_SAVED_PC): Changed name of argument from "frame" to
3468
        "FRAME" to avoid problems with replacement of "->frame" part of
3469
        macro.
3470
 
3471
        * i386-dep.c (i386_get_frame_setup): Added codestream_get() to
3472
        move codestream pointer up to the correct location in "subl $X,
3473
        %esp" case.
3474
 
3475
Sun Jan  1 14:24:35 1989  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3476
 
3477
        * valprint.c (val_print): Rewrote routine to print string pointed
3478
        to by char pointer; was producing incorrect results when print_max
3479
        was 0.
3480
 
3481
Fri Dec 30 12:13:35 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3482
 
3483
        * dbxread.c (read_dbx_symtab, process_symbol_for_psymtab): Put
3484
        everything on the misc function list.
3485
 
3486
        * Checkpointed distribution.
3487
 
3488
        * Makefile: Added expread.tab.c to the list of things slated for
3489
        distribution.

3493
        * stack.c (set_backtrace_limit_command, backtrace_limit_info,
3494
        bactrace_command, _initialize_stack): Removed modifications for
3495
        limit on backtrace.  Piping the backtrace through an interuptable
3496
        "more" emulation is a better way to do it.
3497
 
3498
Wed Dec 28 11:43:09 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3499
 
3500

3501
        (set_backtrace_limit_command): Added command to set a limit to the
3502
        number of frames for a backtrace to print by default.
3503
        (backtrace_limit_info): To print the current limit.
3504
        (backtrace_command): To use the limit.
3505
        (_initialize_stack): To initialize the limit to its default value
3506
        (30), and add the set and info commands onto the appropriate
3507
        command lists.
3508
 
3509
        * gdb.texinfo: Documented changes to "backtrace" and "commands"
3510
        commands.
3511
 
3512
        * stack.c (backtrace_command): Altered so that a negative argument
3513
        would show the last few frames on the stack instead of the first
3514
        few.
3515
        (_initialize_stack): Modified help documentation.
3516
 
3517
        * breakpoint.c (commands_command): Altered so that "commands" with
3518
        no argument would refer to the last breakpoint set.
3519
        (_initialize_breakpoint): Modified help documentation.
3520
 
3521
        * infrun.c (wait_for_inferior): Removed ifdef on Sun4; now you can
3522
        single step through compiler generated sub calls and will die if
3523
        you next off of the end of a function.
3524
 
3525
        * sparc-dep.c (single_step): Fixed typo; "break_insn" ==> "sizeof
3526
        break_insn".
3527
 
3528
        * m-sparc.h (INIT_EXTRA_FRAME_INFO): Set the bottom of a stack
3529
        frame to be the bottom of the stack frame inner from this, if that
3530
        inner one is a leaf node.
3531
 
3532
        * dbxread.c (read_dbx_symtab): Check to make sure we don't add a
3533
        psymtab to it's own dependency list.
3534
 
3535
        * dbxread.c (read_dbx_symtab): Modified check for duplicate
3536
        dependencies to catch them correctly.
3537
 
3538

3541
        pointer as argument.
3542
        * stack.c (frame_info), blockframe.c (get_prev_frame_info),
3543

3550
        * m-vax.h, m-umax.h, m-npl.h, infrun.c (wait_for_inferior),
3551
        blockframe.c (get_prev_frame_info): Modified SAVED_PC_AFTER_CALL
3552
        to take a frame info pointer as an argument.
3553
 
3554
        * blockframe.c (get_prev_frame_info): Altered the use of the
3555
        macros FRAME_CHAIN, FRAME_CHAIN_VALID, and FRAME_CHAIN_COMBINE to
3556
        use frame info pointers as arguments instead of frame addresses.
3557
        * m-vax.h, m-umax.h, m-sun3.h, m-sun3.h, m-sparc.h, m-pn.h,
3558
        m-npl.h, m-news.h, m-merlin.h, m-isi.h, m-hp9k320.h, m-i386.h:
3559
        Modified definitions of the above macros to suit.
3560
        * m-pn.h, m-npl.h, gould-dep.c (findframe): Modified findframe to
3561
        use a frame info argument; also fixed internals (wouldn't work
3562
        before).
3563
 
3564
        * m-sparc.h: Cosmetic changes; reordered some macros and made sure
3565
        that nothing went over 80 lines.
3566
 
3567
Thu Dec 22 11:49:15 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3568
 
3569
        * Version 3.0 released.
3570
 
3571
        * README: Deleted note about changing -lobstack to obstack.o.
3572
 
3573
Wed Dec 21 11:12:47 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3574
 
3575
        * m-vax.h (SKIP_PROLOGUE): Now recognizes gcc prologue also.
3576
 
3577
        * blockframe.c (get_prev_frame_info): Added FUNCTION_START_OFFSET
3578
        to result of get_pc_function_start.
3579
        * infrun.c (wait_for_inferior): Same.
3580
 
3581
        * gdb.texinfo: Documented new "step" and "next" behavior in
3582
        functions without line number information.
3583
 
3584
Tue Dec 20 18:00:45 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3585
 
3586
        * infcmd.c (step_1): Changed behavior of "step" or "next" in a
3587
        function witout line number information.  It now sets the step
3588
        range around the function (to single step out of it) using the
3589
        misc function vector, warns the user, and continues.
3590
 
3591
        * symtab.c (find_pc_line): Zero "end" subsection of returned
3592
        symtab_and_line if no symtab found.
3593
 
3594
Mon Dec 19 17:44:35 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3595
 
3596
        * i386-pinsn.c (OP_REG): Added code from pace to streamline
3597
        disassembly and corrected types.
3598
        * i386-dep.c
3599
        (i386_follow_jump): Code added to follow byte and word offset
3600
        branches.
3601
        (i386_get_frame_setup): Expanded to deal with more wide ranging
3602
        function prologue.
3603
        (i386_frame_find_saved_regs, i386_skip_prologue): Changed to use
3604
        i386_get_frame_setup.
3605
 
3606
 
3607
Sun Dec 18 11:15:03 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3608
 
3609
        * m-sparc.h: Deleted definition of SUN4_COMPILER_BUG; was designed
3610
        to avoid something that I consider a bug in our code, not theirs,
3611
        and which I fixed earlier.  Also deleted definition of
3612
        CANNOT_USE_ARBITRARY_FRAME; no longer used anywhere.
3613
        FRAME_SPECIFICATION_DYADIC used instead.
3614
 
3615
        * infrun.c (wait_for_inferior): On the sun 4, if a function
3616
        doesn't have a prologue, a next over it single steps into it.
3617
        This gets around the problem of a "call .stret4" at the end of
3618
        functions returning structures.
3619
        * m-sparc.h: Defined SUN4_COMPILER_FEATURE.
3620
 
3621
        * main.c (copying_info): Seperated the last printf into two
3622
        printfs.  The 386 compiler will now handle it.
3623
 
3624
        * i386-pinsn.c, i386-dep.c: Moved print_387_control_word,
3625
        print_387_status_word, print_387_status, and i386_float_info to
3626
        dep.c  Also included reg.h in dep.c.

3629
 
3630
        * main.c (source_command): Don't close instream if it's null
3631
        (indicating execution of a user-defined command).
3632
                 (execute_command): Set instream to null before executing
3633
                 commands and setup clean stuff to put it back on error.
3634
 
3635
        * inflow.c (terminal_inferior): Went back to not checking the
3636
        ioctl returns; there are some systems when this will simply fail.
3637
        It seems that, on most of these systems, nothing bad will happen
3638
        by that failure.
3639
 
3640
        * values.c (value_static_field): Fixed dereferencing of null
3641
        pointer.
3642
 
3643
        * i386-dep.c (i386_follow_jump): Modified to deal with
3644
        unconditional byte offsets also.
3645
 
3646
        * dbxread.c (read_type): Fixed typo in function type case of switch.
3647
 
3648
        * infcmd.c (run_command): Does not prompt to restart if command is
3649
        not from a tty.
3650
 
3651
Fri Dec 16 15:21:58 1988  Randy Smith  (randy at calvin)
3652
 
3653
        * gdb.texinfo: Added a third option under the "Cannot Insert
3654
        Breakpoints" workarounds.
3655
 
3656
        * printcmd.c (display_command): Don't do the display unless there
3657
        is an active inferior; only set it.
3658
 
3659
        * findvar.c (value_of_register): Added an error check for calling
3660
        this when the inferior isn't active and a core file isn't being
3661
        read.
3662
 
3663
        * config.gdb: Added reminder about modifying REGEX in the
3664
        makefile for the 386.
3665
 
3666
        * i386-pinsn.c, i386-dep.c: Moved m-i386.h helper functions over
3667
        to i386-dep.c.b
3668

3670
 
3671
        * README: Added a couple of notes about compiling gdb with itself.
3672
 
3673
        * breakpoint.c (set_momentary_breakpoint): Only takes FRAME_FP of
3674
        frame if frame is non-zero.
3675
 
3676
        * printcmd.c (print_scalar_formatted): Implemented /g size for
3677
        hexadecimal format on machines without an 8 byte integer type.  It
3678
        seems to be non-trivial to implement /g for other formats.
3679
        (decode_format): Allowed hexadecimal format to make it through /g
3680
        fileter.
3681
 
3682
Wed Dec 14 13:27:04 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
3683
 
3684
        * expread.y: Converted all calls to write_exp_elt from the parser
3685
        to calls to one of write_exp_elt_{opcode, sym, longcst, dblcst,
3686
        char, type, intern}.  Created all of these routines.  This gets
3687
        around possible problems in passing one of these things in one ear
3688
        and getting something different out the other.  Eliminated
3689
        SUN4_COMPILER_BUG ifdef's; they are now superfluous.
3690
 
3691
        * symmisc.c (free_all_psymtabs): Reinited partial_symtab_list to 0.
3692
                    (_initialize_symmisc): Initialized both symtab_list and
3693
                    partial_symtab_list.
3694
 
3695
        * dbxread.c (start_psymtab): Didn't allocate anything on
3696
        dependency list.
3697
        (end_psymtab): Allocate dependency list on psymbol obstack from
3698
        local list.
3699
        (add_psymtab_dependency): Deleted.
3700
        (read_dbx_symtab): Put dependency on local list if it isn't on it
3701
        already.
3702
 
3703
        * symtab.c: Added definition of psymbol_obstack.
3704
        * symtab.h: Added declaration of psymbol_obstack.
3705
        * symmisc.c (free_all_psymtabs): Added freeing and
3706
        reinitionaliztion of psymbol_obstack.
3707
        * dbxread.c (free_all_psymbols): Deleted.
3708
                    (start_psymtab, end_psymtab,
3709
                    process_symbol_for_psymtab):  Changed most allocation
3710
                    of partial symbol stuff to be off of psymbol_obstack.
3711
 
3712
        * symmisc.c (free_psymtab, free_all_psymtabs): Deleted
3713
        free_psymtab subroutine.
3714
 
3715
        * symtab.h: Removed num_includes and includes from partial_symtab
3716
        structure; no longer needed now that all include files have their
3717
        own psymtab.
3718
        * dbxread.c (start_psymtab): Eliminated initialization of above.
3719
                    (end_psymtab): Eliminated finalization of above; get
3720
                    includes from seperate list.
3721
                    (read_dbx_symtab): Moved includes from psymtab list to
3722
                    their own list; included in call to end_psymtab.
3723
        * symmisc.c (free_psymtab): Don't free includes.
3724
 
3725
Tue Dec 13 14:48:14 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3726
 
3727
        * i386-pinsn.c: Reformatted entire file to correspond to gnu
3728
        software indentation conventions.
3729
 
3730
        * sparc-dep.c (skip_prologue): Added capability of recognizign
3731
        stores of input register parameters into stack slots.
3732
 
3733
        * sparc-dep.c: Added an include of sparc-opcode.h.
3734
        * sparc-pinsn.c, sparc-opcode.h: Moved insn_fmt structures and
3735
        unions from pinsn.c to opcode.h.
3736
        * sparc-pinsn.c, sparc-dep.c (isabranch, skip_prologue): Moved
3737
        this function from pinsn.c to dep.c.
3738
 
3739
        * Makefile: Put in warnings about compiling with gcc (non-ansi
3740
        include files) and compiling with shared libs on Sunos 4.0 (can't
3741
        debug something that's been compiled that way).
3742
 
3743
        * sparc-pinsn.c: Put in a completely new file (provided by
3744
        Tiemann) to handle floating point disassembly, load and store
3745
        instructions, and etc. better.  Made the modifications this file
3746
        (ChangeLog) list for sparc-pinsn.c again.
3747
 
3748
        * symtab.c (output_source_filename): Included "more" emulation hack.
3749
 
3750
        * symtab.c (output_source_filename): Initialized COLUMN to 0.
3751
                   (sources_info): Modified to not print out a line for
3752
                   all of the include files within a partial symtab (since
3753
                   they have pst's of their own now).  Also modified to
3754
                   make a distinction between those pst's read in and
3755
                   those not.
3756
 
3757
        * infrun.c: Included void declaration of single_step() if it's
3758
        going to be used.
3759
        * sparc-dep.c (single_step): Moved function previous to use of it.
3760
 
3761
        * Makefile: Took removal of expread.tab.c out of make clean entry
3762
        and put it into a new "squeakyclean" entry.
3763
 
3764
Mon Dec 12 13:21:02 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
3765
 
3766
        * sparc-pinsn.c (skip_prologue): Changed a struct insn_fmt to a
3767
        union insn_fmt.
3768
 
3769
        * inflow.c (terminal_inferior): Checked *all* return codes from
3770
        ioctl's and fcntl's in routine.
3771
 
3772
        * inflow.c (terminal_inferior): Added check for sucess of
3773
        TIOCSPGRP ioctl call.  Just notifies if bad.
3774
 
3775
        * dbxread.c (symbol_file_command): Close was getting called twice;
3776
        once directly and once through cleanup.  Killed the direct call.
3777
 
3778
Sun Dec 11 19:40:40 1988  & Smith  (randy at hobbes.ai.mit.edu)
3779
 
3780
        * valprint.c (val_print): Deleted spurious printing of "=" from
3781
        TYPE_CODE_REF case.
3782
 
3783
Sat Dec 10 16:41:07 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
3784
 
3785
        * dbxread.c: Changed allocation of psymbols from using malloc and
3786
        realloc to using obstacks.  This means they aren't realloc'd out
3787
        from under the pointers to them.
3788
 
3789
Fri Dec  9 10:33:24 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3790
 
3791
        * sparc-dep.c inflow.c core.c expread.y command.c infrun.c
3792
        infcmd.c dbxread.c symmisc.c symtab.c printcmd.c valprint.c
3793
        values.c source.c stack.c findvar.c breakpoint.c blockframe.c
3794
        main.c: Various cleanups inspired by "gcc -Wall" (without checking
3795
        for implicit declarations).
3796
 
3797
        * Makefile: Cleaned up some more.
3798
 
3799
        * valops.c, m-*.h (FIX_CALL_DUMMY): Modified to take 5 arguments
3800
        as per what sparc needs (programming for a superset of needed
3801
        args).
3802
 
3803
        * dbxread.c (process_symbol_for_psymtab): Modified to be slightly
3804
        more picky about what it puts on the list of things *not* to be
3805
        put on the misc function list.  When/if I shift everything over to
3806
        being placed on the misc_function_list, this will go away.
3807
 
3808
        * inferior.h, infrun.c: Added fields to save in inferior_status
3809
        structure.
3810
 
3811
        * maketarfile: Deleted; functionality is in Makefile now.
3812
 
3813
        * infrun.c (wait_for_inferior): Modified algorithm for determining
3814
        whether or not a single-step was through a subroutine call.  See
3815
        comments at top of file.
3816
 
3817
        * dbxread.c (read_dbx_symtab): Made sure that the IGNORE_SYMBOL
3818
        macro would be checked during initial readin.
3819
 
3820
        * dbxread.c (read_ofile_symtab): Added macro GCC_COMPILED_FLAG_SYMBOL
3821
        into dbxread.c to indicate what string in a local text symbol will
3822
        indicate a file compiled with gcc.  Defaults to "gcc_compiled.".
3823
 
3824
Thu Dec  8 11:46:22 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3825
 
3826
        * m-sparc.h (FRAME_FIND_SAVED_REGS): Cleaned up a little to take
3827
        advantage of the new frame cache system.
3828
 
3829
        * inferior.h, infrun.c, valops.c, valops.c, infcmd.c:  Changed
3830
        mechanism to save inferior status over calls to inferior (eg.
3831
        call_function); implemented save_inferior_info and
3832
        restore_inferior_info.
3833
 
3834
        * blockframe.c (get_prev_frame): Simplified this by a direct call
3835
        to get_prev_frame_info.
3836
 
3837
        * frame.h, stack.c, printcmd.c, m-sparc.h, sparc-dep.c: Removed
3838
        all uses of frame_id_from_addr.  There are short routines like it
3839
        still in frame_saved_pc (m-sparc.h) and parse_frame_spec
3840
        (stack.c).  Eventually the one in frame_saved_pc will go away.
3841
 
3842
        * infcmd.c, sparc-dep.c: Implemented a new mechanism for
3843
        re-selecting the selected frame on return from a call.
3844
 
3845
        * blockframe.c, stack.c, findvar.c, printcmd.c, m-*.h:  Changed
3846
        all routines and macros that took a "struct frame_info" as an
3847
        argument to take a "struct frame_info *".  Routines: findarg,
3848
        framechain, print_frame_args, FRAME_ARGS_ADDRESS,
3849
        FRAME_STRUCT_ARGS_ADDRESS, FRAME_LOCALS_ADDRESS, FRAME_NUM_ARGS,
3850
        FRAME_FIND_SAVED_REGS.
3851
 
3852
        * frame.h, stack.c, printcmd.c, infcmd.c, findvar.c, breakpoint.c,
3853
        blockframe.c, xgdb.c, i386-pinsn.c, gld-pinsn.c, m-umax.h,
3854
        m-sun2.h, m-sun3.h, m-sparc.h, m-pn.h, m-npl.h, m-news.h,
3855
        m-merlin.h, m-isi.h, m-i386.h, m-hp9k320.h:  Changed routines to
3856
        use "struct frame_info *" internally.
3857
 
3858
Wed Dec  7 12:07:54 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3859
 
3860
        * frame.h, blockframe.c, m-sparc.h, sparc-dep.c: Changed all calls
3861
        to get_[prev_]frame_cache_item to get_[prev_]frame_info.
3862
 
3863
        * blockframe.c: Elminated get_frame_cache_item and
3864
        get_prev_frame_cache_item; functionality now taken care of by
3865
        get_frame_info and get_prev_frame_info.
3866
 
3867
        * blockframe.c: Put allocation on an obstack and eliminated fancy
3868
        reallocation routines, several variables, and various nasty
3869
        things.
3870
 
3871
        * frame.h, stack.c, infrun.c, blockframe.c, sparc-dep.c: Changed
3872
        type FRAME to be a typedef to "struct frame_info *".  Had to also
3873
        change routines that returned frame id's to return the pointer
3874
        instead of the cache index.
3875
 
3876
        * infcmd.c (finish_command): Used proper method of getting from
3877
        function symbol to start of function.  Was treating a symbol as a
3878
        value.
3879
 
3880
        * blockframe.c, breakpoint.c, findvar.c, infcmd.c, stack.c,
3881
        xgdb.c, i386-pinsn.c, frame.h, m-hp9k320.h, m-i386.h, m-isi.h,
3882
        m-merlin.h, m-news.h, m-npl.h, m-pn.h, m-sparc.h, m-sun2.h,
3883
        m-sun3.h, m-umax.h: Changed get_frame_info and get_prev_frame_info
3884
        to return pointers instead of structures.
3885
 
3886
        * blockframe.c (get_pc_function_start): Modified to go to misc
3887
        function table instead of bombing if pc was in a block without a
3888
        containing function.
3889
 
3890
        * coffread.c: Dup'd descriptor passed to read_coff_symtab and
3891
        fdopen'd it so that there wouldn't be multiple closes on the same
3892
        fd.  Also put (fclose, stream) on the cleanup list.
3893
 
3894
        * printcmd.c, stack.c: Changed print_frame_args to take a
3895
        frame_info struct as argument instead of the address of the args
3896
        to the frame.
3897
 
3898
        * m-i386.h (STORE_STRUCT_RETURN): Decremented sp by sizeof object
3899
        to store (an address) rather than 1.
3900
 
3901
        * dbxread.c (read_dbx_symtab): Set first_object_file_end in
3902
        read_dbx_symtab (oops).
3903
 
3904
        * coffread.c (fill_in_vptr_fieldno): Rewrote TYPE_BASECLASS as
3905
        necessary.
3906
 
3907
Tue Dec  6 13:03:43 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3908
 
3909
        * coffread.c: Added fake support for partial_symtabs to allow
3910
        compilation and execution without there use.
3911
        * inflow.c: Added a couple of minor USG mods.
3912
        * munch: Put in appropriate conditionals so that it would work on
3913
        USG systems.
3914
        * Makefile: Made regex.* handled same as obstack.*; made sure tar
3915
        file included everything I wanted it to include (including
3916
        malloc.c).
3917
 
3918
        * dbxread.c (end_psymtab): Create an entry in the
3919
        partial_symtab_list for each subfile of the .o file just read in.
3920
        This allows a "list expread.y:10" to work when we haven't read in
3921
        expread.o's symbol stuff yet.
3922
 
3923
        * symtab.h, dbxread.c (psymtab_to_symtab): Recognize pst->ldsymlen
3924
        == 0 as indicating a dummy psymtab, only in existence to cause the
3925
        dependency list to be read in.
3926
 
3927
        * dbxread.c (sort_symtab_syms): Elminated reversal of symbols to
3928
        make sure that register debug symbol decls always come before
3929
        parameter symbols.  After mod below, this is not needed.
3930
 
3931
        * symtab.c (lookup_block_symbol): Take parameter type symbols
3932
        (LOC_ARG or LOC_REGPARM) after any other symbols which match.
3933
 
3934
        * dbxread.c (read_type): When defining a type in terms of some
3935
        other type and the other type is supposed to have a pointer back
3936
        to this specific kind of type (pointer, reference, or function),
3937
        check to see if *that* type has been created yet.  If it has, use
3938
        it and fill in the appropriate slot with a pointer to it.
3939
 
3940
Mon Dec  5 11:25:04 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3941
 
3942
        * symmisc.c: Eliminated existence of free_inclink_symtabs and
3943
        init_free_inclink_symtabs; they aren't called from anywhere, and
3944
        if they were they could disrupt gdb's data structure badly
3945
        (elimination of struct type's which values that stick around past
3946
        elimination of inclink symtabs).
3947
 
3948
        * dbxread.c (symbol_file_command): Fixed a return pathway out of
3949
        the routine to do_cleanups before it left.
3950
 
3951
        * infcmd.c (set_environment_command), gdb.texinfo: Added
3952
        capability to set environmental variable values to null.
3953
 
3954

Sun Dec  4 17:03:16 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
3957
 
3958
        * dbxread.c (symbol_file_command): Added check; if there weren't
3959
        any debugging symbols in the file just read, the user is warned.
3960
 
3961
        * infcmd.c: Commented set_environment_command (a little).
3962
 
3963
        * createtags: Cleaned up and commented.
3964
 
3965
        * Makefile: Updated dependency list and cleaned it up somewhat
3966
        (used macros, didn't make .o files depend on .c files, etc.)
3967

Fri Dec  2 11:44:46 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3969
 
3970
        * value.h, values.c, infcmd.c, valops.c, m-i386.h, m-sparc.h,
3971
        m-merlin.h, m-npl.h, m-pn.h, m-umax.h, m-vax.h, m-hp9k320.h,
3972
        m-isi.h, m-news.h, m-sun2.h, m-sun3.h:  Cleaned up dealings with
3973
        functions returning structures.  Specifically: Added a function
3974
        called using_struct_return which indicates whether the function
3975
        being called is using the structure returning conventions or it is
3976
        using the value returning conventions on that machine.  Added a
3977
        macro, STORE_STRUCT_RETURN to store the address of the structure
3978
        to be copied into wherever it's supposed to go, and changed
3979
        call_function to handle all of this correctly.
3980
 
3981
        * symseg.h, symtab.h, dbxread.c: Added hooks to recognize an
3982
        N_TEXT symbol with name "*gcc-compiled*" as being a flag
3983
        indicating that a file had been compiled with gcc and setting a
3984
        flag in all blocks produced during processing of that file.
3985
 
3986
Thu Dec  1 13:54:29 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3987
 
3988
        * m-sparc.h (PUSH_DUMMY_FRAME): Saved 8 less than the current pc,
3989
        as POP_FRAME and sparc return convention restore the pc to 8 more
3990
        than the value saved.
3991
 
3992
        * valops.c, printcmd.c, findvar.c, value.h: Added the routine
3993
        value_from_register, to access a specific register of a specific
3994
        frame as containing a specific type, and used it in read_var_value
3995
        and print_frame_args.
3996
 
3997
Wed Nov 30 17:39:50 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
3998
 
3999
        * dbxread.c (read_number): Will accept either the argument passed
4000
        as an ending character, or a null byte as an ending character.
4001
 
4002
        * Makefile, createtags: Added entry to create tags for gdb
4003
        distribution which will make sure currently configured machine
4004
        dependent files come first in the list.
4005
 
4006
Wed Nov 23 13:27:34 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
4007
 
4008
        * stack.c, infcmd.c, sparc-dep.c: Modified record_selected_frame
4009
        to work off of frame address.
4010
 
4011
        * blockframe.c (create_new_frame, get_prev_frame_cache_item):
4012
        Added code to reset pointers within frame cache if it must be
4013
        realloc'd.
4014
 
4015
        * dbxread.c (read_dbx_symtab): Added in optimization comparing
4016
        last couple of characters instead of first couple to avoid
4017
        strcmp's in read_dbx_symtab (recording extern syms in misc
4018
        functions or not).  1 call to strlen is balanced out by many fewer
4019
        calls to strcmp.
4020
 
4021
Tue Nov 22 16:40:14 1988  Randall Smith  (randy at cream-of-wheat.ai.mit.edu)
4022
 
4023
        * dbxread.c (read_dbx_symtab): Took out optimization for ignoring
4024
        LSYM's; was disallowing typedefs.  Silly me.
4025
 
4026
        * Checkpointed distribution (mostly for sending to Tiemann).
4027
 
4028
        * expression.h: Added BINOP_MIN and BINOP_MAX operators for C++.
4029
        * symseg.h: Included flags for types having destructors and
4030
                constructors, and flags being defined via public and via
4031
                virtual paths.  Added fields NEXT_VARIANT, N_BASECLASSES,
4032
                and BASECLASSES to this type (tr: Changed types from
4033
                having to be derived from a single baseclass to a multiple
4034
                base class).
4035
        * symtab.h: Added macros to access new fields defined in symseg.h.
4036
                Added decl for lookup_basetype_type.
4037
        * dbxread.c
4038
        (condense_addl_misc_bunches): Function added to condense the misc
4039
                function bunches added by reading in a new .o file.

        (read_addl_syms): Function added to read in symbols
4041
                from a new .o file (incremental linking).
4042
        (add_file_command): Command interface function to indicate
4043
                incrmental linking of a new .o file; this now calls
4044
                read_addl_syms and condense_addl_misc_bunches.
4045
        (define_symbol): Modified code to handle types defined from base
4046
                types which were not known when the derived class was
4047
                output.
4048
        (read_struct_type): Modified to better handle description of
4049
                struct types as derived types.  Possibly derived from
4050
                several different base classes.  Also added new code to
4051
                mark definitions via virtual paths or via public paths.
4052
                Killed seperate code to handle classes with destructors
4053
                but without constructors and improved marking of classes
4054
                as having destructors and constructors.
4055
        * infcmd.c: Modified call to val_print (one more argument).
4056
        * symtab.c (lookup_member_type): Modified to deal with new
4057
                structure in symseg.h.

        (lookup_basetype_type): Function added to find or construct a type
4059
                ?derived? from the given type.
4060
        (decode_line_1): Modified to deal with new type data structures.
4061
                Modified to deal with new number of args for
4062
                decode_line_2.
4063
        (decode_line_2): Changed number of args (?why?).
4064
        (init_type): Added inits for new C++ fields from
4065
                symseg.h.
4066
        *valarith.c
4067
        (value_x_binop, value_binop): Added cases for BINOP_MIN &
4068
                BINOP_MAX.
4069
        * valops.c
4070
        (value_struct_elt, check_field, value_struct_elt_for_address):
4071
                Changed to deal with multiple possible baseclasses.
4072
        (value_of_this): Made SELECTED_FRAME an extern variable.
4073
        * valprint.c
4074
        (val_print): Added an argument DEREF_REF to dereference references
4075
                automatically, instead of printing them like pointers.
4076
                Changed number of arguments in recursive calls to itself.
4077
                Changed to deal with varibale numbers of base classes.
4078
        (value_print): Changed number of arguments to val_print.  Print
4079
                type of value also if value is a reference.
4080
        (type_print_derivation_info): Added function to print out
4081
                derivation info a a type.
4082
        (type_print_base): Modified to use type_print_derivation_info and
4083
                to handle multiple baseclasses.
4084
 
4085
Mon Nov 21 10:32:07 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
4086
 
4087
        * inflow.c (term_status_command): Add trailing newline to output.
4088
 
4089
        * sparc-dep.c (do_save_insn, do_restore_insn): Saved
4090
        "stop_registers" over the call for the sake of normal_stop and
4091
        run_stack_dummy.
4092
 
4093
        * m-sparc.h (EXTRACT_RETURN_VALUE): Put in parenthesis to force
4094
        addition of 8 to the int pointer, not the char pointer.
4095
 
4096
        * sparc-pinsn.c (print_addr1): Believe that I have gotten the
4097
        syntax right for loads and stores as adb does it.
4098
 
4099
        * symtab.c (list_symbols): Turned search for match on rexegp into
4100
        a single loop.
4101
 
4102
        * dbxread.c (psymtab_to_symtab): Don't read it in if it's already
4103
        been read in.
4104
 
4105
        * dbxread.c (psymtab_to_symtab): Changed error to fatal in
4106
        psymtab_to_symtab.
4107
 
4108
        * expread.y (parse_number): Fixed bug which treated 'l' at end of
4109
        number as '0'.
4110
 
4111
Fri Nov 18 13:57:33 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
4112
 
4113
        * dbxread.c (read_dbx_symtab, process_symbol_for_psymtab): Was
4114
        being foolish and using pointers into an array I could realloc.
4115
        Converted these pointers into integers.
4116
 
4117
Wed Nov 16 11:43:10 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
4118
 
4119
        * m-sparc.h (POP_FRAME): Made the new frame be PC_ADJUST of the
4120
        old frame.
4121
 
4122
        * i386-pinsn.c, m-hp9k320.h, m-isi.h, m-merlin.h, m-news.h,
4123
        m-npl.h, m-pn.h, m-sparc.h, m-sun2.h, m-sun3.h, m-umax.h, m-vax.h:
4124
        Modified POP_FRAME to use the current frame instead of
4125
        read_register (FP_REGNUM) and to flush_cached_frames before
4126
        setting the current frame.  Also added a call to set the current
4127
        frame in those POP_FRAMEs that didn't have it.
4128
 
4129
        * infrun.c (wait_for_inferior): Moved call to set_current_frame up
4130
        to guarrantee that the current frame will always be set when a
4131
        POP_FRAME is done.
4132
 
4133
        * infrun.c (normal_stop): Added something to reset the pc of the
4134
        current frame (was incorrect because of DECR_PC_AFTER_BREAK).
4135
 
4136
        * valprint.c (val_print): Changed to check to see if a string was
4137
        out of bounds when being printed and to indicate this if so.
4138
 
4139
        * convex-dep.c (read_inferior_memory): Changed to return the value
4140
        of errno if the call failed (which will be 0 if the call
4141
        suceeded).
4142
 
4143
Tue Nov 15 10:17:15 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
4144
 
4145
        * infrun.c (wait_for_inferior): Two changes: 1) Added code to
4146
        not trigger the step breakpoint on recursive calls to functions
4147
        without frame info, and 2) Added calls to distinguish recursive
4148
        calls within a function without a frame (which next/nexti might
4149
        wish to step over) from jumps to the beginning of a function
4150
        (which it generally doesn't).
4151
 
4152
        * m-sparc.h (INIT_EXTRA_FRAME_INFO): Bottom set correctly for leaf
4153
        parents.
4154
 
4155
        * blockframe.c (get_prev_frame_cache_item): Put in mod to check
4156
        for a leaf node (by presence or lack of function prologue).  If
4157
        there is a leaf node, it is assumed that SAVED_PC_AFTER_CALL is
4158
        valid.  Otherwise, FRAME_SAVED_PC or read_pc is used.
4159
 
4160
        * blockframe.c, frame.h: Did final deletion of unused routines and
4161
        commented problems with getting a pointer into the frame cache in
4162
        the frame_info structure comment.
4163
 
4164
        * blockframe.c, frame.h, stack.c: Killed use of
4165
        frame_id_from_frame_info; used frame_id_from_addr instead.
4166
 
4167
        * blockframe.c, frame.h, stack.c, others (oops): Combined stack
4168
        cache and frame info structures.
4169
 
4170
        * blockframe.c, sparc-dep.c, stack.c: Created the function
4171
        create_new_frame and used it in place of bad calls to
4172
        frame_id_from_addr.
4173
 
4174
        * blockframe.c, inflow.c, infrun.c, i386-pinsn.c, m-hp9k320.h,
4175
        m-npl.h, m-pn.h, m-sparc.h, m-sun3.h, m-vax.h, default-dep.c,
4176
        convex-dep.c, gould-dep.c, hp9k320-dep.c, news-dep.c, sparc-dep.c,
4177
        sun3-dep.c, umax-dep.c: Killed use of
4178
        set_current_Frame_by_address.  Used set_current_frame
4179
        (create_new_frame...) instead.
4180
 
4181
        * frame.h: Killed use of FRAME_FP_ID.
4182
 
4183
        * infrun.c, blockframe.c: Killed select_frame_by_address.  Used
4184
        select_frame (get_current_frame (), 0) (which was correct in all
4185
        cases that we need to worry about.
4186

Mon Nov 14 14:19:32 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
4188
 
4189
        * frame.h, blockframe.c, stack.c, m-sparc.h, sparc-dep.c: Added
4190
        mechanisms to deal with possible specification of frames
4191
        dyadically.
4192
 
4193
Sun Nov 13 16:03:32 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
4194
 
4195
        * ns32k-opcode.h: Add insns acbw, acbd.
4196
 
4197
Sun Nov 13 15:09:58 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
4198
 
4199
        * breakpoint.c: Changed breakpoint structure to use the address of
4200
        a given frame (constant across inferior runs) as the criteria for
4201
        stopping instead of the frame ident (which varies across inferior
4202
        calls).
4203
 
4204
Fri Nov 11 13:00:22 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
4205
 
4206
        * gld-pinsn.c (findframe): Modified to work with the new frame
4207
        id's.  Actually, it looks as if this routine should be called with
4208
        an address anyway.
4209
 
4210
        * findvar.c (find_saved_register): Altered bactrace loop to work
4211
        off of frames and not frame infos.
4212
 
4213
        * frame.h, blockframe.c, stack.c, sparc-dep.c, m-sparc.h: Changed
4214
        FRAME from being the address of the frame to being a simple ident
4215
        which is an index into the frame_cache_item list.
4216
        * convex-dep.c, default-dep.c, gould-dep.c, hp9k320-dep.c,
4217
        i386-pinsn.c, inflow.c, infrun.c, news-dep.c, sparc-dep.c,
4218
        sun3-dep.c, umax-dep.c, m-hp9k320.h, m-npl.h, m-pn.h, m-sparc.h,
4219
        m-sun3.h, m-vax.h: Changed calls of the form set_current_frame
4220
        (read_register (FP_REGNUM)) to set_current_frame_by_address (...).
4221
 
4222
Thu Nov 10 16:57:57 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
4223
 
4224
        * frame.h, blockframe.c, gld-pinsn.c, sparc-dep.c, stack.c,
4225
        infrun.c, findvar.c, m-sparc.h: Changed the FRAME type to be
4226
        purely an identifier, using FRAME_FP and FRAME_FP_ID to convert
4227
        back and forth between the two.  The identifier is *currently*
4228
        still the frame pointer value for that frame.
4229
 
4230
Wed Nov  9 17:28:14 1988  Chris Hanson  (cph at kleph)
4231
 
4232
        * m-hp9k320.h (FP_REGISTER_ADDR): Redefine this to return
4233
        difference between address of given FP register, and beginning of
4234
        `struct user' that it occurs in.
4235
 
4236
        * hp9k320-dep.c (core_file_command): Fix sign error in size
4237
        argument to myread.  Change buffer argument to pointer; was
4238
        copying entire structure.
4239
        (fetch_inferior_registers, store_inferior_registers): Replace
4240
        occurrences of `FP_REGISTER_ADDR_DIFF' with `FP_REGISTER_ADDR'.
4241
        Flush former definition.
4242

4244
 
4245
        * xgdb.c: Killed include of initialize.h.
4246
 
4247
        * Pulled in xgdb.c from the net.
4248
 
4249
        * Checkpointed distribution (to provide to 3b2 guy).
4250
 
4251
        * coffread.c, dbxread.c, symmisc.c, symtab.c, symseg.h: Changed
4252
        format of table of line number--pc mapping information.  Can
4253
        handle negative pc's now.
4254
 
4255
        * command.c: Deleted local copy of savestring; code in utils.c is
4256
        identical.
4257
 
4258
Tue Nov  8 11:12:16 1988  Randall Smith  (randy at plantaris.ai.mit.edu)
4259
 
4260
        * gdb.texinfo: Added documentation for shell escape.
4261
 
4262
Mon Nov  7 12:27:16 1988  Randall Smith  (randy at sugar-bombs.ai.mit.edu)
4263
 
4264
        * command.c: Added commands for shell escape.
4265
 
4266
        * core.c, dbxread.c: Added ROBOTUSSIN mods.
4267
 
4268
        * Checkpointed distribution.
4269
 
4270
        * printcmd.c (x_command): Yanked error if there is no memory to
4271
        examine (could be looking at executable straight).
4272
 
4273
        * sparc-pinsn.c (print_insn): Amount to leftshift sethi imm by is
4274
        now 10 (matches adb in output).
4275
 
4276
        * printcmd.c (x_command): Don't attempt to set $_ & $__ if there
4277
        is no last_examine_value (can happen if you did an x/0).
4278
 
4279
Fri Nov  4 13:44:49 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
4280
 
4281
        * printcmd.c (x_command): Error if there is no memory to examine.
4282
 
4283
        * gdb.texinfo: Added "cont" to the command index.
4284
 
4285
        * sparc-dep.c (do_save_insn): Fixed typo in shift amount.
4286
 
4287
        * m68k-opcode.h: Fixed opcodes for 68881.
4288
 
4289
        * breakpoint.c, infcmd.c, source.c: Changed defaults in several
4290
        places for decode_line_1 to work off of the default_breakpoint_*
4291
        values instead of current_source_* values (the current_source_*
4292
        values are off by 5 or so because of listing defaults).
4293
 
4294
        * stack.c (frame_info): ifdef'd out FRAME_SPECIFCATION_DYADIC in
4295
        the stack.c module.  If I can't do this right, I don't want to do
4296
        it at all.  Read the comment there for more info.
4297
 
4298
Mon Oct 31 16:23:06 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
4299
 
4300
        * gdb.texinfo: Added documentation on the "until" command.
4301
 
4302
Sat Oct 29 17:47:10 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
4303
 
4304
        * breakpoint.c, infcmd.c: Added UNTIL_COMMAND and subroutines of
4305
        it.
4306
 
4307
        * breakpoint.c, infcmd.c, infrun.c: Added new field to breakpoint
4308
        structure (silent, indicating a silent breakpoint), and modified
4309
        breakpoint_stop_status and things that read it's return value to
4310
        understand it.
4311
 
4312
Fri Oct 28 17:45:33 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
4313
 
4314
        * dbxread.c, symmisc.c: Assorted speedups for readin, including
4315
        special casing most common symbols, and doing buffering instead of
4316
        calling malloc.
4317
 
4318
Thu Oct 27 11:11:15 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
4319
 
4320
        * stack.c, sparc-dep.c, m-sparc.h: Modified to allow "info frame"
4321
        to take two arguments on the sparc and do the right thing with
4322
        them.
4323
 
4324
        * dbxread.c (read_dbx_symtab, process_symbol_for_psymtab): Put
4325
        stuff to put only symbols that didn't have debugging info on the
4326
        misc functions list back in.
4327
 
4328
Wed Oct 26 10:10:32 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
4329
 
4330
        * valprint.c (type_print_varspec_suffix): Added check for
4331
        TYPE_LENGTH(TYPE_TARGET_TYPE(type)) > 0 to prevent divide by 0.
4332
 
4333
        * printcmd.c (print_formatted): Added check for VALUE_REPEATED;
4334
        value_print needs to be called for that.
4335
 
4336
        * infrun.c (wait_for_inferior): Added break when you decide to
4337
        stop on a null function prologue rather than continue stepping.
4338
 
4339
        * m-sun3.h: Added explanatory comment to REGISTER_RAW_SIZE.
4340
 
4341
        * expread.y (parse_c_1): Initialized paren_depth for each parse.
4342
 
4343
Tue Oct 25 14:19:38 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
4344
 
4345
        * valprint.c, coffread.c, dbxread.c: Enum constant values in enum
4346
        type now accessed through TYPE_FIELD_BITPOS.
4347
 
4348
        * dbxread.c (process_symbol_for_psymtab): Added code to deal with
4349
        possible lack of a ":" in a debugging symbol (do nothing).
4350
 
4351
        * symtab.c (decode_line_1): Added check in case of all numbers for
4352
        complete lack of symbols.
4353
 
4354
        * source.c (select_source_symtab): Made sure that this wouldn't
4355
        bomb on complete lack of symbols.
4356
 
4357
Mon Oct 24 12:28:29 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
4358
 
4359
        * m-sparc.h, findvar.c: Ditched REGISTER_SAVED_UNIQUELY and based
4360
        code on REGISTER_IN_WINDOW_P and HAVE_REGISTER_WINDOWS.  This will
4361
        break when we find a register window machine which saves the
4362
        window registers within the context of an inferior frame.
4363
 
4364
        * sparc-dep.c (frame_saved_pc): Put PC_ADJUST return back in for
4365
        frame_saved_pc.  Seems correct.
4366
 
4367
        * findvar.c, m-sparc.h: Created the macro REGISTER_SAVED_UNIQUELY
4368
        to handle register window issues (ie. that find_saved_register
4369
        wasn't checking the selected frame itself for shit).
4370
 
4371
        * sparc-dep.c (core_file_command): Offset target of o & g register
4372
        bcopy by 1 to hit correct registers.
4373
 
4374
        * m-sparc.h: Changed STACK_END_ADDR.
4375
 
4376
Sun Oct 23 19:41:51 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
4377
 
4378
        * sparc-dep.c (core_file_command): Added in code to get the i & l
4379
        registers from the stack in the corefile, and blew away some wrong
4380
        code to get i & l from inferior.
4381
 
4382
Fri Oct 21 15:09:19 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
4383
 
4384
        * m-sparc.h (PUSH_DUMMY_FRAME): Saved the value of the RP register
4385
        in the location reserved for i7 (in the created frame); this way
4386
        the rp value won't get lost.  The pc (what we put into the rp in
4387
        this routine) gets saved seperately, so we loose no information.
4388
 
4389
        * sparc-dep.c (do_save_insn & do_restore_insn): Added a wrapper to
4390
        preserve the proceed status state variables around each call to
4391
        proceed (the current frame was getting munged because this wasn't
4392
        being done).
4393
 
4394
        * m-sparc.h (FRAME_FIND_SAVED_REGS): Fix bug: saved registers
4395
        addresses were being computed using absolute registers number,
4396
        rather than numbers relative to each group of regs.
4397
 
4398
        * m-sparc.h (POP_FRAME): Fixed a bug (I hope) in the context
4399
        within which saved reg numbers were being interpetted.  The
4400
        values to be restored were being gotten in the inferior frame, and
4401
        the restoring was done in the superior frame.  This means that i
4402
        registers must be restored into o registers.
4403
 
4404
        * sparc-dep.c (do_restore_insn): Modified to take a pc as an
4405
        argument, instead of a raw_buffer.  This matches (at least it
4406
        appears to match) usage from POP_FRAME, which is the only place
4407
        from which do_restore_insn is called.
4408
 
4409
        * sparc-dep.c (do_save_insn and do_restore_insn): Added comments.
4410
 
4411
        * m-sparc.h (FRAME_FIND_SAVED_REGS): Modified my code to find the
4412
        save addresses of out registers to use the in regs off the stack
4413
        pointer when the current frame is 1 from the innermost.
4414
 
4415
Thu Oct 20 13:56:15 1988  & Smith  (randy at hobbes.ai.mit.edu)
4416
 
4417
        * blockframe.c, m-sparc.h: Removed code associated with
4418
        GET_PREV_FRAME_FROM_CACHE_ITEM.  This code was not needed for the
4419
        sparc; you can always find the previous frames fp from the fp of
4420
        the current frame (which is the sp of the previous).  It's getting
4421
        the information associated with a given frame (ie. saved
4422
        registers) that's a bitch, because that stuff is saved relative to
4423
        the stack pointer rather than the frame pointer.
4424
 
4425
        * m-sparc.h (GET_PREV_FRAME_FROM_CACHE_ITEM): Modified to return
4426
        the frame pointer of the previous frame instead of the stack
4427
        pointer of same.
4428
 
4429
        * blockframe.c (flush_cached_frames): Modified call to
4430
        obstack_free to free back to frame_cache instead of back to zero.
4431
        This leaves the obstack control structure in finite state (and
4432
        still frees the entry allocated at frame_cache).
4433
 
4434
Sat Oct 15 16:30:47 1988  & Smith  (randy at tartarus.uchicago.edu)
4435
 
4436
        * valops.c (call_function): Suicide material here.  Fixed a typo;
4437
        CALL_DUMMY_STACK_ADJUST was spelled CAll_DUMMY_STACK_ADJUST on
4438
        line 530 of the file.  This cost me three days.  I'm giving up
4439
        typing for lent.
4440
 
4441
Fri Oct 14 15:10:43 1988  & Smith  (randy at tartarus.uchicago.edu)
4442
 
4443
        * m-sparc.h: Corrected a minor mistake in the dummy frame code
4444
        that was getting the 5th argument and the first argument from the
4445
        same place.
4446
 
4447
Tue Oct 11 11:49:33 1988  & Smith  (randy at tartarus.uchicago.edu)
4448
 
4449
        * infrun.c: Made stop_after_trap and stop_after_attach extern
4450
        instead of static so that code which used proceed from machine
4451
        dependent files could fiddle with them.
4452
 
4453
        * blockframe.c, frame.h, sparc-dep.c, m-sparc.h: Changed sense of
4454
        ->prev and ->next in struct frame_cache_item to fit usage in rest
4455
        of gdb (oops).
4456
 
4457
Mon Oct 10 15:32:42 1988  Randy Smith  (randy at gargoyle.uchicago.edu)
4458
 
4459
        * m-sparc.h, sparc-dep.c, blockframe.c, frame.h: Wrote
4460
        get_frame_cache_item.  Modified FRAME_SAVED_PC and frame_saved_pc
4461
        to take only one argument and do the correct thing with it.  Added
4462
        the two macros I recently defined in blockframe.c to m-sparc.h.
4463
        Have yet to compile this thing on a sparc, but I've now merged in
4464
        everything that I received from tiemann, either exactly, or simply
4465
        effectively.
4466
 
4467
        * source.c: Added code to allocated space to sals.sals in the case
4468
        where no line was specified.
4469
 
4470
        * blockframe.c, infrun.c: Modified to cache stack frames requested
4471
        to minimize accesses to subprocess.
4472
 
4473
Tue Oct  4 15:10:39 1988  Randall Smith  (randy at cream-of-wheat.ai.mit.edu)
4474
 
4475
        * config.gdb: Added sparc.
4476
 
4477
Mon Oct  3 23:01:22 1988  Randall Smith  (randy at cream-of-wheat.ai.mit.edu)
4478
 
4479
        * Makefile, blockframe.c, command.c, core.c, dbxread.c, defs.h,
4480
        expread.y, findvar.c, infcmd.c, inflow.c, infrun.c, sparc-pinsn.c,
4481
        m-sparc.h, sparc-def.c, printcmd.c, stack.c, symmisc.c, symseg.h,
4482
        valops.c, values.c: Did initial merge of sparc port.  This will
4483
        not compile; have to do stack frame caching and finish port.
4484
 
4485
        * inflow.c, gdb.texinfo: `tty' now resets the controling terminal.
4486
 
4487
Fri Sep 30 11:31:16 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
4488
 
4489
        * inferior.h, infcmd.c, infrun.c: Changed the variable
4490
        stop_random_signal to stopped_by_random signal to fit in better
4491
        with name conventions (variable is not a direction to the
4492
        proceed/resume set; it is information from it).
4493
 
4494
Thu Sep 29 13:30:46 1988  Randall Smith  (randy at cream-of-wheat.ai.mit.edu)
4495
 
4496
        * infcmd.c (finish_command): Value type of return value is now
4497
        whatever the function returns, not the type of the function (fixed
4498
        a bug in printing said value).
4499
 
4500
        * dbxread.c (read_dbx_symtab, process_symbol_for_psymtab):
4501
        Put *all* global symbols into misc_functions.  This is what was
4502
        happening anyway, and we need it for find_pc_misc_function.
4503
 
4504
        ** This was eventually taken out, but I didn't mark it in the
4505
        ChangeLog.  Oops.
4506
 
4507
        * dbxread.c (process_symbol_for_psymtab): Put every debugger
4508
        symbol which survives the top case except for constants on the
4509
        symchain.  This means that all of these *won't* show up in misc
4510
        functions (this will be fixed once I make sure it's broken the way
4511
        it's supposed to be).
4512
 
4513
        * dbxread.c: Modified placement of debugger globals onto the hash
4514
        list; now we exclude the stuff after the colon and don't skip the
4515
        first character (debugger symbols don't have underscores).
4516
 
4517
        * dbxread.c: Killed debuginfo stuff with ifdef's.
4518
 
4519
Wed Sep 28 14:31:51 1988  Randall Smith  (randy at cream-of-wheat.ai.mit.edu)
4520
 
4521
        * symtab.h, dbxread.c: Modified to deal with BINCL, EINCL, and
4522
        EXCL symbols produced by the sun loader by adding a list of
4523
        pre-requisite partial_symtabs that each partial symtab needs.
4524
 
4525
        * symtab.h, dbxread.c, symtab.c, symmisc.c: Modified to avoid
4526
        doing a qsort on the local (static) psymbols for each file to
4527
        speed startup.  This feature is not completely debugged, but it's
4528
        inclusion has forced the inclusion of another feature (dealing
4529
        with EINCL's, BINCL's and EXCL's) and so I'm going to go in and
4530
        deal with them.
4531
 
4532
        * dbxread.c (process_symbol_for_psymtab): Made sure that the class
4533
        of the symbol made it into the partial_symbol entry.
4534
 
4535
Tue Sep 27 15:10:26 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
4536
 
4537
        * dbxread.c: Fixed bug; init_psymbol_list was not being called
4538
        with the right number of arguments (1).
4539
 
4540
        * dbxread.c: Put ifdef's around N_MAIN, N_M2C, and N_SCOPE to
4541
        allow compilation on a microvax.
4542
 
4543
        * config.gdb: Modified so that "config.gdb vax" would work.
4544
 
4545
        * dbxread.c, symtab.h, symmisc.h, symtab.c, source.c: Put in many
4546
        and varied hacks to speed up gdb startup including: A complete
4547
        rewrite of read_dbx_symtab, a modification of the partial_symtab
4548
        data type, deletion of select_source_symtab from
4549
        symbol_file_command, and optimiztion of the call to strcmp in
4550
        compare_psymbols.
4551
 
4552
Thu Sep 22 11:08:54 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
4553
 
4554
        * dbxread.c (psymtab_to_symtab): Removed call to
4555
        init_misc_functions.
4556
 
4557
        * dbxread.c: Fixed enumeration type clash (used enum instead of
4558
        integer constant).
4559
 
4560
        * breakpoint.c: Fixed typo; lack of \ at end of line in middle of
4561
        string constant.
4562
 
4563
        * symseg.h: Fixed typo; lack of semicolon after structure
4564
        definition.
4565
 
4566
        * command.c, breakpoint.c, printcmd.c: Added cmdlist editing
4567
        functions to add commands with the abbrev flag set.  Changed
4568
        help_cmd_list to recognize this flag and modified unset,
4569
        undisplay, and enable, disable, and delete breakpoints to have
4570
        this flag set.

Wed Sep 21 13:34:19 1988  Randall Smith  (randy at plantaris.ai.mit.edu)
4573
 
4574
        * breakpoint.c, infcmd.c, gdb.texinfo: Created "unset" as an alias
4575
        for delete, and changed "unset-environment" to be the
4576
        "environment" subcommand of "delete".
4577
 
4578
        * gdb.texinfo, valprint.c: Added documentation in the manual for
4579
        breaking the set-* commands into subcommands of set.  Changed "set
4580
        maximum" to "set array-max".
4581
 
4582
        * main.c, printcmd.c, breakpoint.c: Moved the declaration of
4583
        command lists into main and setup a function in main initializing
4584
        them to guarrantee that they would be initialized before calling
4585
        any of the individual files initialize routines.
4586
 
4587
        * command.c (lookup_cmd): A null string subcommand is treated as
4588
        an unknown subcommand rather than an ambiguous one (eg. "set $x =
4589
        1" will now work).
4590
 
4591
        * infrun.c (wait_for_inferior): Put in ifdef for Sony News in
4592
        check for trap by INNER_THAN macro.
4593
 
4594
        * eval.c (evaluate_subexp): Put in catch to keep the user from
4595
        attempting to call a non function as a function.
4596
 
4597
Tue Sep 20 10:35:53 1988  Randall Smith  (randy at oatmeal.ai.mit.edu)
4598
 
4599
        * dbxread.c (read_dbx_symtab): Installed code to keep track of
4600
        which global symbols did not have debugger symbols refering to
4601
        them, and recording these via record_misc_function.
4602
 
4603
        * dbxread.c: Killed code to check for extra global symbols in the
4604
        debugger symbol table.
4605
 
4606
        * printcmd.c, breakpoint.c: Modified help entries for several
4607
        commands to make sure that abbreviations were clearly marked and
4608
        that the right commands showed up in the help listings.
4609
 
4610
        * main.c, command.c, breakpoint.c, infcmd.c, printcmd.c,
4611
        valprint.c, defs.h: Modified help system to allow help on a class
4612
        name to show subcommands as well as commands and help on a command
4613
        to show *all* subcommands of that command.
4614
 
4615
Fri Sep 16 16:51:19 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
4616
 
4617
        * breakpoint.c (_initialize_breakpoint): Made "breakpoints"
4618
        subcommands of enable, disable, and delete use class 0 (ie. they
4619
        show up when you do a help xxx now).
4620
 
4621
        * infcmd.c,printcmd,c,main.c,valprint.c: Changed the set-*
4622
        commands into subcommands of set.  Created "set variable" for use
4623
        with variables whose names might conflict with other subcommands.
4624
 
4625
        * blockframe.c, dbxread.c, coffread.c, expread.y, source.c:
4626
        Fixed mostly minor (and one major one in block_for_pc) bugs
4627
        involving checking the partial_symtab_list when a scan through the
4628
        symtab_list fails.
4629
 
4630
Wed Sep 14 12:02:05 1988  Randall Smith  (randy at sugar-smacks.ai.mit.edu)
4631
 
4632
        * breakpoint.c, gdb.texinfo: Added enable breakpoints, disable
4633
        breakpoints and delete breakpoints as synonyms for enable,
4634
        disable, and delete.  This seemed reasonable because of the
4635
        immeninent arrival of watchpoints & etc.
4636
 
4637
        * gdb.texinfo: Added enable display, disable display, and delete
4638
        display to manual.
4639
 
4640
Tue Sep 13 16:53:56 1988  Randall Smith  (randy at sugar-smacks.ai.mit.edu)
4641
 
4642
        * inferior.h, infrun.c, infcmd.c: Added variable
4643
        stop_random_signal to indicate when a proceed had been stopped by
4644
        an unexpected signal.  Used this to determine (in normal_stop)
4645
        whether the current display point should be deleted.
4646
 
4647
        * valops.c: Fix to value_ind to check for reference before doing a
4648
        COERCE_ARRAY.
4649
 
4650
Sun Jul 31 11:42:36 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
4651
 
4652
        * breakpoint.c (_initialize_breakpoint): Clean up doc for commands
4653
        that can now apply also to auto-displays.
4654
 
4655
        * coffread.c (record_line): Corrected a spazz in editing.
4656
        Also removed the two lines that assume line-numbers appear
4657
        only in increasing order.
4658
 
4659
Tue Jul 26 22:19:06 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
4660
 
4661
        * expression.h, eval.c, expprint.c, printcmd.c, valarith.c,
4662
        valops.c, valprint.c, values.c, m-*.h: Changes for evaluating and
4663
        displaying 64-bit `long long' integers.  Each machine must define
4664
        a LONGEST type, and a BUILTIN_TYPE_LONGEST.
4665
 
4666
        * symmisc.c: (print_symtab) check the status of the fopen and call
4667
        perror_with_name if needed.
4668
 
4669
Thu Jul 21 00:56:11 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
4670
 
4671
        * Convex: core.c: changes required by Convex's SOFF format were
4672
        isolated in convex-dep.c.
4673
 
4674
Wed Jul 20 21:26:10 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
4675
 
4676
        * coffread.c, core.c, expread.y, i386-pinsn.c, infcmd.c, inflow.c,
4677
        infrun.c, m-i386.h, main.c, remote.c, source.c, valops.c:
4678
        Improvements for the handling of the i386 and other machines
4679
        running USG.  (Several of these files just needed extra header files
4680
        such as types.h.) utils.c: added bcopy, bcmp, bzero, getwd, list
4681
        of signals, and queue routines for USG systems.  Added vfork macro
4682
        to i386
4683
 
4684
        * printcmd.c, breakpoint.c: New commands to enable/disable
4685
        auto-displays.  Also `delete display displaynumber' works like
4686
        `undisplay displaynumber'.
4687
 
4688
Tue Jul 19 02:17:18 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
4689
 
4690
        * coffread.c: (coff_lookup_type)  Wrong portion of type_vector was
4691
        being bzero'd after type_vector was reallocated.
4692
 
4693
        * printcmd.c: (delete_display) Check for a display chain before
4694
        attempting to delete a display.
4695
 
4696
        * core.c, *-dep.c (*-infdep moved to *-dep): machine-dependent
4697
        parts of core.c (core_file_command, exec_file_command) moved to
4698
        *-dep.c.
4699
 
4700
Mon Jul 18 19:45:51 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
4701
 
4702
        * dbxread.c: typo in read_struct_type (missing '=') was causing a
4703
        C struct to be parsed as a C++ struct, resulting in a `invalid
4704
        character' message.
4705
 
4706
Sun Jul 17 22:27:32 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
4707
 
4708
        * printcmd.c, symtab.c, valops.c, expread.y: When an expression is
4709
        read, the innermost block required to evaluate the expression is
4710
        saved in the global variable `innermost_block'.  This information
4711
        is saved in the `block' field of an auto-display so that
4712
        expressions with inactive variables can be skipped.  `info display'
4713
        tells the user which displays are active and which are not.  New
4714
        fn `contained_in' returns nonzero if one block is contained within
4715
        another.
4716
 
4717
Fri Jul 15 01:53:14 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
4718
 
4719
        * infrun.c, m-i386.h: Use macro TRAPS_EXPECTED to set number of
4720
        traps to skip when sh execs the program.  Default is 2, m-i386.h
4721
        overrides this and sets to 4.
4722
 
4723
        * coffread.c, infrun.c: minor changes for the i386.  May be able
4724
        to eliminate them with more general code.
4725
 
4726
        * default-infdep.c: #ifdef SYSTEMV, include header file types.h.
4727
        Also switched the order of signal.h and user.h, since System 5
4728
        requires signal.h to come first.
4729
 
4730
        * core.c main.c, remote,c, source.c, inflow.c: #ifdef SYSTEMV,
4731
        include various header files.  Usually types.h and fcntl.h.
4732
 
4733
        * utils.c: added queue routines needed by the i386 (and other sys
4734
        5 machines).
4735
 
4736
        * sys5.c, regex.c, regex.h: new files for sys 5 systems.  (The
4737
        regex files are simply links to /gp/gnu/lib.)
4738
 
4739
Thu Jul 14 01:47:14 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
4740
 
4741
        * config.gdb, README: Provide a list of known machines when user
4742
        enters an invalid machine.  New second arg is operating system,
4743
        currently only used with `sunos4' or `os4'. Entry for i386 added.
4744
 
4745
        * news-infdep.c: new file.
4746
 
4747
        * m-news.h: new version which deals with new bugs in news800's OS.
4748
 
4749
Tue Jul 12 19:52:16 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
4750
 
4751
        * Makefile, *.c, munch, config.gdb, README: New initialization
4752
        scheme uses nm to find functions whose names begin with
4753
        `_initialize_'.  Files `initialize.h', `firstfile.c',
4754
        `lastfile.c', `m-*init.h' no longer needed.
4755
 
4756
        * eval.c, symtab.c, valarith.c, valops.c, value.h, values.c: Bug
4757
        fixes from gdb+ 2.5.4.  evaluate_subexp takes a new arg, type
4758
        expected. New fn value_virtual_fn_field.
4759
 
4760
Mon Jul 11 00:48:49 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
4761
 
4762
        * core.c (read_memory): xfer_core_file was being called with an
4763
        extra argument (0) by read_memory.
4764
 
4765
        * core.c (read_memory), *-infdep.c (read_inferior_memory),
4766
        valops.c (value_at): read_memory and read_inferior_memory now work
4767
        like write_memory and write_inferior_memory in that errno is
4768
        checked after each ptrace and returned to the caller.  Used in
4769
        value_at to detect references to addresses which are out of
4770
        bounds.  Also core.c (xfer_core_file): return 1 if invalid
4771
        address, 0 otherwise.
4772
 
4773
        * inflow.c, -infdep.c: removed all calls to ptrace from
4774
        inflow.c and put them in machine-dependent files *-infdep.c.
4775
 
4776
Sun Jul 10 19:19:36 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
4777
 
4778
        * symmisc.c: (read_symsegs) Accept only format number 2.  Since
4779
        the size of the type structure changed when C++ support was added,
4780
        format 1 can no longer be used.
4781
 
4782
        * core.c, m-sunos4.h: (core_file_command) support for SunOS 4.0.
4783
        Slight change in the core structure.  #ifdef SUNOS4.  New file
4784
        m-sunos4.h.  May want to change config.gdb also.
4785
 
4786
Fri Jul  8 19:59:49 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
4787
 
4788
        * breakpoint.c: (break_command_1) Allow `break if condition'
4789
        rather than parsing `if' as a function name and returning an
4790
        error.
4791
 
4792
Thu Jul  7 22:22:47 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
4793
 
4794
        * C++: valops.c, valprint.c, value.h, values.c: merged code to deal
4795
        with C++ expressions.
4796
 
4797
Wed Jul  6 03:28:18 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
4798
 
4799
        * C++: dbxread.c: (read_dbx_symtab, condense_misc_bunches,
4800
        add_file_command)  Merged code to read symbol information from
4801
        an incrementally linked file.  symmisc.c:
4802
        (init_free_inclink_symtabs, free_inclink_symtabs) Cleanup
4803
        routines.
4804
 
4805
Tue Jul  5 02:50:41 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
4806
 
4807
        * C++: symtab.c, breakpoint.c, source.c:  Merged code to deal with
4808
        ambiguous line specifications.  In C++ one can have overloaded
4809
        function names, so that `list classname::overloadedfuncname'
4810
        refers to several different lines, possibly in different files.
4811
 
4812
Fri Jul  1 02:44:20 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
4813
 
4814
        * C++: symtab.c: replaced lookup_symtab_1 and lookup_symtab_2 with
4815
        a modified lookup_symbol which checks for fields of the current
4816
        implied argument `this'.  printcmd.c, source.c, symtab.c,
4817
        valops.c: Need to change callers once callers are
4818
        installed.
4819
 
4820
Wed Jun 29 01:26:56 1988  Peter TerMaat  (pete at frosted-flakes.ai.mit.edu)
4821
 
4822
        * C++: eval.c, expprint.c, expread.y, expression.h, valarith.c,
4823
        Merged code to deal with evaluation of user-defined operators,
4824
        member functions, and virtual functions.
4825
        binop_must_be_user_defined tests for user-defined binops,
4826
        value_x_binop calls the appropriate operator function.
4827
 
4828
Tue Jun 28 02:56:42 1988  Peter TerMaat  (pete at frosted-flakes.ai.mit.edu)
4829
 
4830
        * C++: Makefile: changed the echo: expect 101 shift/reduce conflicts
4831
        and 1 reduce/reduce conflict.
4832
