  32 Tue Jul 26 03:05:28 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
  33
  34         * symmisc.c: (print_symtabs)  Check the status of the fopen and
  35         call perror_with_name if needed.
  36

  43
  44         * main.c: New vars win_argv, win_argc, win_prgm to talk to xgdb.
  45
  46 Thu Jul  7 02:05:29 1988  Pete TerMaat  (pete at frosted-flakes.ai.mit.edu)
  47
  48         * dbxread.c: (define_symbol) store static functions ('f') in the
  49         same way as global functions ('F') -- that is, as `function of
  50         type X' rather than as `X'.
  51
  52 Mon Jul  4 17:07:31 1988  Pete TerMaat  (pete at frosted-flakes.ai.mit.edu)
  53
  54         * dbxread.c: (read_dbx_symtab) Avoid reading symbol tables of
  55         libraries by checking for symbols which begin with "-l" (in
  56         addition to those which end with ".o").
  57
  58 Mon Jun 27 23:27:51 1988  Pete TerMaat  (pete at frosted-flakes.ai.mit.edu)
  59
  60         * dbxread.c: (define_symbol) and coffread.c: (process_coff_symbol)
  61         If the current symbol is a function, assign its type to be
  62         `function of type X' rather than `X'.  TYPE_TARGET_TYPE (symbol)
  63         is `X'
  64
  65         * findvar.c: (locate_var_value, read_var_value) got rid of checks
  66         for LOC_BLOCK which called `lookup_function_type'.  These checks
  67         are no longer needed because of the change to dbxread.c.
  68
  69         * infcmd.c: (finish_command) Now uses target_type instead of type
  70         for functions, in keeping with the change to dbxread.c.
  71
  72 Sat Jun 25 00:24:09 1988  Pete TerMaat  (pete at corn-chex.ai.mit.edu)
  73
  74         * infrun.c: (normal_stop) Added a check for permissions on the
  75         exec file before printing the "You have encountered a bug in sh"
  76         message.  Apparently on some systems an attempt by the shell to
  77         exec an unexecutable file had resulted in the "You have
  78         encountered" message.
  79
  80 Wed Jun 22 00:00:02 1988  Pete TerMaat  (pete at corn-chex.ai.mit.edu)
  81
  82         * config.gdb: installed shell script to make the proper links to
  83         param.h, m-init.h, opcode.h, and pinsn.c, given a machine name.
  84
  85 Tue Jun 21 23:55:09 1988  Pete TerMaat  (pete at corn-chex.ai.mit.edu)
  86
  87         * m-suninit.h, m-isi-ov.h, m-news800.h: moved to m-sun3init.h,
  88         m-isi.h, m-news.h for consistency.
  89
  90 Fri Jun 17 21:24:48 1988  Pete TerMaat  (pete at lucky-charms.ai.mit.edu)
  91
  92         * m-umax.h: (FIX_CALL_DUMMY): fixed typo (the last `flipped' was
  93         `fliped')
  94
  95         * m-pn.h, m-npl.h: added #define gould, since this is needed in
  96         core.c.
  97
  98 Tue Jun 14 04:07:50 1988  Pete TerMaat  (pete at lucky-charms.ai.mit.edu)
  99
 100         * Removed unused variables from m-pn.h, m-npl.h in
 101         FRAME_FIND_SAVED_REGS, PUSH_DUMMY_FRAME, and POP_FRAME.
 102
 103 Mon Jun 13 05:57:47 1988  Richard Stallman  (rms at corn-chex.ai.mit.edu)
 104
 105         * inflow.c (create_inferior): Allow two macros SHELL_FILE and
 106         SHELL_COMMAND_CONCAT, if defined, to customize how the shell is run.
 107

 113
 114         * dbxread.c (read_dbx_symtab): Change handling of N_NBTEXT (Gould).
 115
 116 Mon May 30 22:48:48 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
 117
 118         * main.c (main, disconnect): Handle SIGHUP by killing inferior.
 119         * inflow.c (kill_inferior_fast): New function used to do that.
 120
 121         * utils.c (printchar): New 3rd arg is the string's delimiter,
 122         which is the char that needs backslashing.
 123         * valprint.c (value_print, val_print): Pass new arg.
 124         * expprint.c (print_subexp): Pass new arg.
 125
 126 Mon May 23 14:54:54 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
 127
 128         * source.c (print_source_lines): New arg NOERROR nonzero means
 129         if file is not found just print message and return (don't throw).
 130         Callers changed here and in stack.c.
 131
 132 Sun May 22 14:22:54 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
 133
 134         * source.c (identify_source_line): Set defaults for `list' command.
 135
 136         * dbxread.c (sort_syms): If not sorting the block, reverse it, so
 137         that for a parm declared register the register comes before the parm.
 138
 139         * defs.h: declare alloca.
 140
 141 Fri May 20 15:02:50 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)

 146
 147         * source.c ({forward,reverse}_search_command, print_source_lines):
 148         Line number symtab->nlines is just barely in range.
 149         (find_source_lines): Newline as last char in file doesn't start a line.
 150
 151 Thu May  5 15:04:40 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
 152
 153         * Version 2.6.
 154
 155         * printcmd.c (do_one_display): New fn, display one auto-display.
 156         (do_displays): Use that fn.

 158
 159         * printcmd.c (do_display): Record # of display being displayed.
 160         (delete_current_display): New fn: delete that display (if any).

 162         * infrun.c (normal_stop): Likewise.
 163
 164         * main.c (catch_error): New fn: like list `errset'.
 165         * breakpoint.c (breakpoint_cond_eval): Eval an expression and
 166         return 1 if the expression is zero.
 167         (breakpoint_stop_status): Use those two fcns; avoid lossage on error
 168         in evalling a breakpoint condition.
 169
 170         * infcmd.c (jump_command): Typo in call to `query'.
 171
 172 Tue May  3 10:52:08 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
 173
 174         * core.c (exec_file_command): If no file, pass 0 to display-hook.
 175
 176         * core.c (get_exec_file): New arg ERR says whether to err if no file.
 177         All callers changed.
 178
 179         * main.c (print_prompt): New fn to print the prompt string.
 180
 181         * xgdb.c: Numerous changes.  It now semi-works but the text display
 182         often gets messed up.
 183
 184 Sun May  1 12:12:43 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
 185
 186         * wait.h [HAVE_WAIT_STRUCT] (WSETSTOP): Fix typos.
 187
 188 Sat Apr 30 10:18:56 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)

 191
 192 Fri Apr 15 01:01:40 1988  Chris Hanson  (cph at kleph)
 193
 194         * inflow.c [! TIOCGPGRP]: Do not call `setpgrp' for inferior.
 195         Instead, disable SIGINT and SIGQUIT while the inferior is running.
 196         Unfortunately this means that C-c typed while GDB is running will
 197         cause the inferior to receive SIGINT when it is resumed.
 198         * utils.c (quit) [! TIOCGPGRP]: Cause quit message to remind user
 199         that the inferior will see SIGINT.
 200
 201 Thu Apr 14 23:38:02 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
 202
 203         * infrun.c (wait_for_inferior): If step into a function, and
 204         immediately arrive at start of first line of user code,
 205         don't step: stop immediately.
 206         Set prev_pc before, not after, calling `resume'.
 207
 208         * source.c (identify_source_line): New 3rd arg controls additional
 209         output datum: `beg' or `middle', saying whether pc is at beg of line.
 210         * stack.c (print_frame_info): Pass that argument.
 211
 212         * main.c (cd_command): Convert any relative pathname to absolute.
 213         Simplify if `.' or `..' appear.

 216
 217         * infrun.c: Add new flag `trap_expected_after_continue' to
 218         compensate for spurious trace trap generated by HP-UX after
 219         running a stack dummy.
 220
 221         * inflow.c (term_status_command) [HAVE_TERMIO]: Show all available
 222         terminal status information.
 223
 224 Tue Apr 12 19:11:00 1988  Chris Hanson  (cph at kleph)
 225
 226         * stack.c (print_frame_info): When -fullname is given and
 227         `identify_source_line' succeeds, do not print real pc even if it
 228         differs from the start pc for the source line.  This information
 229         is not very useful and tends to screw up gdb-mode in emacs.
 230
 231 Mon Apr 11 14:22:10 1988  Chris Hanson  (cph at kleph)
 232
 233         * dbxread.c (define_symbol): Don't forget to terminate
 234         SYMBOL_NAME.
 235
 236         * m-hp9k320.h (CALL_DUMMY): Fix bug -- breakpoint instruction is
 237         TRAP #1 not TRAP #15.
 238
 239         * inflow.c (store_inferior_register_1) [HP9K320]: Ignore `errno',
 240         as there is a bug in HP-UX which (mistakenly) causes errno to be
 241         non-zero when writing fp7.
 242
 243 Sat Apr  9 01:04:23 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
 244
 245         * dbxread.c (symbol_file_command): Check stringtab size by doing `stat'
 246         and, if it is ridiculous, complain and don't call alloca.
 247         Don't discard existing symtab until after that check.
 248
 249 Fri Apr  8 16:39:11 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
 250
 251         * Makefile: Delete `-lg' entirely; not needed now that linking is done
 252         with $(CC).
 253
 254 Fri Apr  8 13:41:46 1988  Chris Hanson  (cph at kleph)
 255
 256         * m68k-opcode.h: Fix operand-string of fmovel insns.
 257
 258         * Makefile: Put "-lg" in CLIBS because there is no such library in
 259         HPUX.  Update the comment for HPUX.
 260
 261 Fri Apr  8 03:30:23 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
 262
 263         * findvar.c (locate_var_value): For &FCN, do lookup_function_type.
 264
 265         * valprint.c (val_print): Fix typo testing whether ptr is a string.

 268
 269         * m-hp9k320.h: New file.
 270
 271         * main.c (stop_sig, read_line): #ifdef SIGTSTP around uses of SIGTSTP.
 272
 273         * wait.h: Fix bug in WSETEXIT.
 274
 275         * remote.c: If HAVE_TERMIO, use termio and fake it to look like stty.
 276         Include wait.h
 277         (remote_wait): Use the wait.h interface.
 278
 279         * utils.c (quit): Need HAVE_TERMIO conditional.  Also include param.h.
 280
 281         * inflow.c: If HAVE_TERMIO, use termio and fake it to look like stty.
 282         Define TERMINAL for data type of terminal data.
 283         Use of tchars, ltchars, pgrp conditional on existence of the
 284         ioctls that handle them.
 285         (terminal_init_inferior, terminal_inferior, terminal_ours,
 286          term_status_command, initialize):
 287         Conditionals for HAVE_TERMIO and existence of various ioctls.
 288         ({fetch,store}_inferior_registers): Separate versions for HP9K320.
 289
 290         * m68k-pinsn.c (convert_{to,from}_68881): Alternate asms for HPUX_ASM.
 291
 292         * core.c (register_addr): Change #ifdef to REGISTER_U_ADDR
 293         (core_file_command) [HP9K320]: Special code to get regs from HPUX
 294         core file.
 295
 296 Thu Apr  7 01:15:56 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
 297
 298         * dbxread.c (add_symbol_to_list, finish_block, read_enum_type):
 299         Symbol-lists now hold up to 20 symbols in each `struct pending'
 300         to save time in malloc.  When a `struct pending' becomes free,
 301         don't call `free'; put it on a free-list `free_pendings'.
 302         (really_free_pendings): Call `free' for each `struct pending'
 303         on the free-list, and others that are easily found.
 304         (symbol_file_command): Set up `really_free_pendings' as a cleanup.
 305
 306         * dbxread.c (start_symtab, end_symtab, process_one_symbol):

 310         in the symbol_obstack.
 311         (obsavestring): New fn, like savestring but alloc in symbol_obstack.
 312         (obconcat): New fn, like concat but etc.
 313         Most calls to savestring and concat changed to call these fns.
 314         (define_symbol): Open-code bcopy; don't bother to zero the symbol.
 315         (compare_symbols): Compare 1st char of name before calling strcmp.
 316
 317         * Do explicit buffering to read symtab--don't use stdio.
 318         Variables symbuf... hold the buffer and indices.
 319         * dbxread.c (fill_symbuf): Fill the buffer, record how much was read.
 320         (read_dbx_symbols, next_symbol_text): Fetch data direct from buffer;
 321         call fill_symbuf when necessary.
 322
 323         * dbxread.c (sort_syms): Don't sort blocks with < 40 syms.
 324         * symtab.c (lookup_block_symbol): Don't binary search such blocks.

 328         (list_symbols): If block not normally sorted, sort it here.
 329
 330         * dbxread.c (define_symbol): Ignore sym if name is empty.
 331         (process_one_symbol): Ignore N_ENTRY sym if no N_SO seen yet.
 332         (read_dbx_symtab): Recognize N_NBTEXT like N_TEXT (if it's defined).
 333         Set end_of_text_addr from END_OF_TEXT_DEFAULT (if it's defined).
 334         (NUMBER_OF_SYMBOLS): New macro for # entries in symtab.
 335         (SYMBOL_TABLE_OFFSET): New macro for file-offset of symtab.

 341         (symbol_file_command): These macros replace open code.
 342
 343         * values.c (unpack_double): When fetching `double' from memory,
 344         make it double-aligned, since some machines need that.
 345
 346         * core.c (exec_file_command): Insert conditionals for `gould'.
 347
 348         * m-sun[23].h, m-isi-ov.h, m-news800.h (ABOUT_TO_RETURN):

1093
1094 Thu Jan 22 00:31:03 1987  Richard M. Stallman  (rms at prep)
1095
1096         * Version 2.0.
1097
1098         * blockframe.c (get_pc_function_start):
1099         Understand misc functions.
1100
1101         * core.c (core_file_command):
1102         Copy all register contents into the array `registers'
1103         Save a.out header of executable file in core_aouthdr.
1104         Print name of executable file that was running, if we know
1105         where to find it.
1106
1107         * core.c (exec_file_command):
1108         Save a.out header in exec_aouthdr and file's mtime
1109         in exec_mtime.
1110
1111         * core.c (validate_files): Check that core file's a.out hdr
1112         matches exec file's.
1113
1114         * New handling of registers:
1115         Now all registers are fetched once when the program stops or
1116         when a core file is selected.  Their contents are kept in
1117         `registers', an array of bytes.  This is done by
1118         `fetch_inferior_registers'.  `read_register', etc., just look
1119         there.  Writing a register works through
1120         `store_inferior_registers' which writes one or all registers
1121         from `registers' back to the inferior.
1122
1123         A register now can have a "raw" data format and a "virtual"
1124         data format, which may require conversion or even be different sizes.
1125         The conversion can be different for different registers.
1126         For example, the 68000 cpu registers need no conversion
1127         and both raw and virtual size is 4, but the 68881 floating point
1128         registers have raw size 12 (for extended fmt) and virtual size 8
1129         (for double).  Macros in the m- file such as REGISTER_BYTES,
1130         REGISTER_BYTE, REGISTER_{RAW,VIRTUAL}_SIZE, and
1131         REGISTER_CONVERT_TO_{RAW,VIRTUAL} control these things.
1132
1133         `read_register' and `write_register' are usable only on registers
1134         which hold an int and need no conversion (raw fmt = virtual fmt).
1135         For other registers, `read_register_bytes' is used, or
1136         `read_relative_register_raw_bytes'.
1137
1138         * m-sun3.h: Define the 68881 fp registers.
1139         Know how to recognize insns that save them.
1140         Make dummy frames save them.

1146         * findvar.c (supply_register): Function used by
1147         fetch_inferior_registers, etc., to install the register

1152
1153         * findvar.c (read_relative_register_raw_bytes):
1154         Replaces old function `read_relative_register'; accepts
1155         address of where to store the contents; # bytes stored is size
1156         of the specified register in raw format.
1157
1158         * findvar.c (value_of_register, read_var_value):
1159         Convert register values and values of register variables
1160         from raw format to virtual format.
1161
1162         * findvar.c (locate_var_value): Like `read_var_value' but
1163         returns value for variable's address.
1164
1165         * value.h: Add new field VALUE_REGNO to each value.  It holds
1166         register number to control virtual-to-raw conversion
1167         for assignments to the value.
1168
1169         * valops.c (value_assign): Convert data from virtual to raw format

1194         * inflow.c ({read,write}_inferior_register): Deleted.
1195
1196         * infrun.c (wait_for_inferior): Single-stepping is not considered
1197         to have hit a breakpoint unless the pc before the step matches the
1198         address of the breakpoint.  Necessary on machines where
1199         breakpoints leave the pc incremented.
1200
1201         If shell gets SIGSEGV, pass the signal silently to it.
1202
1203         * m68k-pinsn.c, m68k-opcode.h:
1204         Add the 68881 instructions.  New operand codes `F', `I', `s'
1205         and `k' are needed for them.  New place codes `78tcik'.
1206         NEXTBYTE now skips a word but fetches just a byte.
1207         Explicit sign-extension removed from NEXTBYTE and NEXTWORD.
1208         NEXTSINGLE, NEXTDOUBLE, NEXTEXTEND and NEXTPACKED defined.
1209         Various changes to implement the new operand and place codes.
1210         print_index changed because displacement-size codes for
1211         word and long displacement were interchanged.
1212
1213         * m68k-pinsn.c (convert_{from,to}_68881): Functions added

1217         * main.c (define_command, document_command):
1218         Accept a from_tty argument instead of calling input_from_terminal_p.
1219
1220         * printcmd.c (address_info): Print info on class and address
1221         of a specified symbol.  For register symbols, gives name of register.
1222
1223         * printcmd.c (print_command): Remember explicitly whether
1224         `make_cleanup' was called.

1236         `exec_mtime' and warn if source is newer.
1237
1238         * source.c (line_info): No arg means use last line listed
1239         or line following last one this command was used on.
1240         If from tty, clear out argument so Return is like `i li' without
1241         arg.
1242
1243         * stack.c (frame_info): Print addresses registers are saved at.
1244
1245         * stack.c (return_command): When asking for confirmation, give
1246         name of function that will be made to return.
1247
1248         * valops.c (call_function): If function type is
1249         pointer-to-function, dereference it to compute return type.
1250         If pointer-to-object, assume function returns int.
1251         If char, assume that the value's address is the function address
1252         (because it's a misc functon).  If int, the value itself is the
1253         function address.
1254
1255         * dbxread.c (compare_symbols): Sort register symbols
1256         before all others.
1257
1258         * eval.c (evaluate_subexp_for_address): New function like

1261
1262         * eval.c (evaluate_subexp_for_sizeof): New function like
1263         `evaluate_subexp' but returns a value for the size of the subexp.
1264
1265         * eval.c (evaluate_subexp_with_coercion): Like `evaluate_subexp'
1266         but coerces arrays to pointers (without taking the time to
1267         read the array contents).
1268
1269         * eval.c (evaluate_subexp): Use the three new functions above
1270         when appropriate instead of calling self recursively.

1448         * dbxread.c (process_one_symbol): Ignore N_NSYMS symbols
1449         that appear in Ultrix.
1450
1451 Sat Nov 22 22:49:06 1986  Richard M. Stallman  (rms at prep)
1452
1453         * version.c: version 1.10.
1454
1455         * valprint.c (type_print*):
1456         SHOW < 0 now means abbreviate struct/union members
1457         or enum values with `...'.  SHOW now decremented on
1458         each recursion in type_print_base.  Several places
1459         that used to check !show now check show <= 0.
1460
1461         * valprint.c (val_print): Pass -1 for SHOW to type_print
1462         when printing typename inside parens or braces.
1463
1464         * printcmd.c (print_command): If no value specified to print,
1465         print the value of $.
1466
1467         * expression.h, expread.y, eval.c, expprint.c:
1468         OP_MEMVAL renamed UNOP_MEMVAL
1469         and now allows any expression, not just an integer address.
1470         It now has same format as UNOP_CAST and works almost like it.
1471         Each place that referred to it has been rewritten
1472         starting with a copy of the code that handles UNOP_CAST.
1473         Doc for `print' command changed for this.
1474
1475         * source.c (init_source_path):
1476         Free and zero out any line_charpos's saved in source symtabs.
1477
1478         * breakpoint.c (condition_command):
1479         Parse the condition in the environment of the code where the
1480         breakpoint is set.  This requires finding the breakpoint
1481         before parsing, so code is rearranged.
1482
1483         * dbxread.c (dbx_alloc_type):
1484         New function given typenums returns the type for those typenums
1485         or allocates a new, empty type for those typenums and returns it.
1486
1487         * symtab.c (smash_type_to_{pointer,function}):
1488         New functions modify an already-allocated type object
1489         to be a pointer to or function returning some given type.
1490
1491         * dbxread.c (read_type): Uses dbx_alloc_type in many cases.
1492         Reading a pointer or function type now works by doing that,
1493         then reading the value type or type pointed to, then smashing
1494         it into the type already allocated.  This makes some fwd refs win.
1495         Likewise for structs and unions.
1496
1497         * dbxread.c (read_struct_type): Now receives the type object
1498         as args.  Used to get typenums as args and look up the type
1499         itself.
1500
1501         * dbxread.c (symbol_file_command):
1502         At very end, clear out any type name that `char *' has received.
1503
1504 Thu Nov 20 16:43:53 1986  Richard M. Stallman  (rms at prep)
1505
1506         * m-sun2.h, m-sun3.h (FIND_FRAME_SAVED_REGS):
1507         Was incrementing address even for regs not saved.
1508
1509 Sun Nov 16 14:59:07 1986  Richard M. Stallman  (rms at prep)
1510
1511         * values.c (value_field): Was adding in byte offset
1512         before calling unpack_field_as_long, which itself
1513         adds in the offset.  Now pass addr of start of structure.
1514
1515         * infrun.c (normal_stop): Clean up inferior_pid conditionals:
1516         just return early if no inferior.
1517
1518 Thu Nov 13 15:45:50 1986  Richard M. Stallman  (rms at prep)
1519
1520         * dbxread.c (struct header_file): add new field .instance
1521         to distinguish the various entries for one header file.
1522
1523         * dbxread.c (process_one_symbol): Use the `value' of
1524         a N_BINCL or N_EXCL as the instance code for the header file.
1525
1526         * dbxread.c (add_{new,old}_header_file):
1527         Accept an instance code as arg and treat it as if it were
1528         part of the file name for distinguishing and finding entries.
1529
1530         * dbxread.c (add_new_header_file, read_type):
1531         Turn off the header_file_prev_index feature with #if 0.
1532
1533         * values.c (unpack_field_as_long, modify_field):
1534         Run-time test to distinguish big and little endian machines
1535         and do shifting accordingly.
1536
1537 Tue Nov 11 00:31:18 1986  Richard M. Stallman  (rms at prep)
1538
1539         * version.c: version 1.9.
1540
1541         * breakpoint.c (delete_command):
1542         Don't query if 2nd arg is zero.
1543
1544         * breakpoint.c (clear_breakpoints):
1545         Pass 2nd arg of zero to delete_command.
1546
1547 Sat Nov  8 23:29:19 1986  Richard M. Stallman  (rms at prep)
1548
1549         * breakpoint.c (delete_command):
1550         Ask for confirmation when used with no arg (delete all).
1551
1552 Fri Nov  7 11:23:09 1986  Richard M. Stallman  (rms at prep)
1553
1554         * infrun.c (start_inferior, wait_for_inferior):
1555         Eliminate `stop_in_shell' which was not being maintained right.
1556         New variable `running_in_shell' is set to 1 or 0 when the
1557         expected SIGTRAPs happen, and is simply examined at other times.
1558
1559         * infrun.c (wait_for_inferior):
1560         If get SIGSEGV with running_in_shell == 1, it is sh
1561         allocating memory.  Pass the signal silently to the shell.
1562
1563         * core.c (exec_file_command):
1564         data_{start,end} are adjusted unconditionally when an
1565         exec file is opened, so closing counter-adjustment is
1566         now unconditional as well.
1567
1568         * printcmd.c (x_command):
1569         Don't erase the expression from the calling args
1570         if cllaed noninteractively (used to be clobbering
1571         definitions of user-defined commands).
1572
1573         * source.c (list_command): likewise.
1574
1575 Wed Nov  5 09:41:00 1986  Richard M. Stallman  (rms at prep)
1576
1577         * Makefile: New variable OBSTACK1 that people can use
1578         to make obstack.o a dependency of gdb.
1579
1580         * breakpoint.c (initialize):
1581         Define new aliases "br", "bre" and "brea" for "break".
1582
1583 Sun Nov  2 21:16:06 1986  Richard Mlynarik  (mly at prep)
1584
1585         * symmisc.c (read_symsegs):
1586         Add an extra protection against invalid symbol-file
1587
1588         * m-vax.h:
1589         Set KERNEL_U_ADDR and STACK_END_ADDR non-4.2-specifically
1590
1591 Tue Oct 21 13:34:14 1986  Richard Mlynarik  (mly at prep)
1592
1593         * breakpoints.c (initialize):
1594         Delet reference to non-existent command "tenable" from doc of "enable"
1595
1596 Tue Oct 14 19:58:27 1986  Richard Mlynarik  (mly at prep)
1597
1598         * printcmd.c (display_command, undisplay_command):
1599         * infcmd.c (run_command):
1600         Call dont_repeat.
