1.1.1.4 ! root        1: Wed Apr 17 15:33:33 1991  Per Bothner  (bothner at pogo.gnu.ai.mit.edu)
        !             2: 
        !             3:        * Make version number be 1.9.
        !             4: 
        !             5: Wed Apr 10 18:19:15 1991  Per Bothner  (bothner at pogo.gnu.ai.mit.edu)
        !             6: 
        !             7:        * strip.c (xmalloc): Handle allocation request of 0 (make it 1).
        !             8: 
        !             9: Tue Apr  9 13:40:31 1991  Per Bothner  (bothner at pogo.gnu.ai.mit.edu)
        !            10: 
        !            11:        * strip.c (rewrite_file_symbols): Instead of tell(fd),
        !            12:        use the more portable lseek(fd, 0L, 1).
        !            13: 
        !            14: Mon Apr  8 17:31:17 1991  Per Bothner  (bothner at pogo.gnu.ai.mit.edu)
        !            15: 
        !            16:        * Makefile: Replaced mis-spelled and obsolete -DPIGNAL_MISSING
        !            17:        by -DSYS_SIGLIST_MISSING in sample CFLAGS for COFF systems.
        !            18: 
        !            19: Sun Mar 31 23:06:42 1991  Per Bothner  (bothner at pogo.gnu.ai.mit.edu)
        !            20: 
        !            21:        * Increment version number to 1.8.
        !            22: 
        !            23: Fri Mar 29 15:29:55 1991  Per Bothner  (bothner at pogo.gnu.ai.mit.edu)
        !            24: 
        !            25:        * ld.c (do_relocation_warnings): Add some paranoia checking
        !            26:        in case of a corrupted binary.
        !            27: 
        !            28: Thu Mar 28 17:21:24 1991  Per Bothner  (bothner at pogo.gnu.ai.mit.edu)
        !            29: 
        !            30:        * ld.c (subfile_wanted_p): Not quite as minimalist:
        !            31:        If a subfile defines a common that is needed (i.e. currently
        !            32:        undefined), don't load the subfile, just define the undefined
        !            33:        symbol as a common.
        !            34:        This brings back some of the logic from Roland's change.
        !            35:        It is needed to handle a dubious libc.a in SunOS.
        !            36: 
        !            37: Sat Mar 23 13:25:07 1991  Per Bothner  (bothner at pogo.gnu.ai.mit.edu)
        !            38: 
        !            39:        * ld.c (subfile_wanted_p): Try a minimalist approach:
        !            40:        Treat an existing common definition as a true definition
        !            41:        wrt the decision as to whether a subfile is needed -
        !            42:        i.e. don't pull in the subfile in that case.
        !            43: 
        !            44: Tue Mar 19 01:01:34 1991  Per Bothner  (bothner at mole.ai.mit.edu)
        !            45: 
        !            46:        * ld.c (subfile_wanted_p): A compromise solution, suggested by Mike:
        !            47:        Restore the old #if 1 behavior, with the following changes:
        !            48:        + allow a library member to grow a common symbol only if some other
        !            49:        library member is already known to reference that symbol
        !            50:        + allow a library member to replace a common symbol with some other
        !            51:        definition if some other library member is already known to
        !            52:        reference that symbol.
        !            53: 
        !            54: Sun Mar 17 00:47:44 1991  Per Bothner  (bothner at pogo.ai.mit.edu)
        !            55: 
        !            56:        * Makefile: Add $(LIBS) to dependencies for most programs,
        !            57:        to make sure signame.o and alloca.o get built when needed.
        !            58:        * ar.c: Don't include fcntl.h again if USG.
        !            59:        * ar.c: Initialize program_name variable.
        !            60:        * ar.c:  Changes from Arnold Robbins <[email protected]>:
        !            61:         "gnu ar didn't properly use just the trailing component
        !            62:         of filenames.  If creating an archive, it would put members in
        !            63:         with names like ./foo.  If updating an archive with a member
        !            64:          foo with /some/path/foo, the new file would get appended to
        !            65:          the archive instead of replacing the old one."
        !            66:        So add basename routine to skip directory prefix, and use it
        !            67:        to name archive elements with just the basename.
        !            68:        Also some System V stuff:
        !            69:        "System V machines (of course) use a slightly different version
        !            70:         of the archive format header, and allow a leading '-' on the
        !            71:         flags.  Also, the temp file name didn't allow for 14 character
        !            72:         file names."
        !            73:        I (Per) incorporated these changes. It seemed reasonable to always
        !            74:        allow an initial '-' to the flags.
        !            75:        * ar.c: Improved argc/argv/usage() checking.
        !            76:        * ar.c: Unlink if we fail to open after "touch" for create.
        !            77:        * gprof.c: Reformat, adding white space between = and &.
        !            78:        Without it, pcc thinks it's an old-style &=.
        !            79:        * ld.c: Code for ns32000 from Jyrki Kuoppala <[email protected]>,
        !            80:        some of it by Ian Dall.
        !            81:        * ld.c (subfile_wanted_p): For now, undo the change made for 1.7.
        !            82:        (It causes problems, and anyway I'm unconvinced by the justification.)
        !            83:        * ranlib.c (main): Removed emulation of psignal when PSIGNAL_MISSING
        !            84:        is defined, since there is a version in signame.c.
        !            85: 
        !            86: Thu Mar  7 17:29:09 1991  Mike Haertel  (mike at ducky)
        !            87: 
        !            88:        * a.out.gnu.h [sequent && i386]:  Changes to support the
        !            89:        sequent symmetry.
        !            90:        * ar.c (update_symdefs):  Loop to original_num_symdefs rather
        !            91:        than nsymdefs, since the latter changes inside the loop.
        !            92:        * gprof.c (main):  Divide by (nhist - 1) to get the correct
        !            93:        histogram increment.
        !            94:        * hp-bin/hpxt.c (process_archive_entry):  Deal correctly with
        !            95:        names containing '/'.
        !            96:        * ld.c [tek4300, LARMAG]:  Add UTek support.
        !            97:        [hp300]: Mark the filename symbol with N_FN|N_EXT not N_TEXT.
        !            98:        (deduce_file_type):  Remove forward reference to coffheader.
        !            99:        (read_a_out_header):  Likewise.
        !           100:        (read_a_out_header) [NMAGIC]:  Adjust orig_data_address when
        !           101:        reading NMAGIC files.
        !           102:        (enter_global_ref):  Update symbol's last_library_ref for
        !           103:        use by subfile_wanted_p().
        !           104:        (subfile_wanted_p):  Never use a library member to define
        !           105:        a common symbol unless some other library member already known
        !           106:        to be needed references that symbol.
        !           107:        (do_file_warnings):  Warn for multiply defined N_ABS symbols.
        !           108:        (do_warnings:  Warn if -e entry symbol is never defined.
        !           109:        (perform_relocation):  Make sure we never carry out of the
        !           110:        relocation masked bits.
        !           111:        (getsym):  Clear last_library_ref to NULL when initializing
        !           112:        a new symbol, for subfile_wanted_p().
        !           113:        ranlib.c [PSIGNAL_MISSING]:  Don't use psignal().
        !           114:        strip.c (file_close):  Use -1 for invalid descriptor flag value.
        !           115:        (read_file_symbols):  Close the file if an error occurs.
        !           116:        (rewrite_file_symbols):  Use ~ prefixed temp file to avoid
        !           117:        problems with 14 character limits on file names.  Use open()
        !           118:        instead of creat() since the file will need to be read later.
        !           119:        Be sure to close all input files.  Cast lseek() arguments
        !           120:        correctly.
        !           121: 
        !           122: Wed Nov 28 23:42:48 1990  Jim Kingdon and Roland McGrath  ([email protected])
        !           123: 
        !           124:        * ld.c (subfile_wanted_p): If the subfile has a common def of
        !           125:        a symbol already defined as common, look at the subfile's def
        !           126:        to find the largest-sized common def.  But do not include the
        !           127:        subfile if the symbol is already defined at all.
        !           128: 
        !           129: Mon Oct 15 13:07:24 1990  Mike Haertel  (mike at albert.ai.mit.edu)
        !           130: 
        !           131:        * ld.c (digest_symbols):  Align the end of the data segment
        !           132:        to sizeof (double) after allocating set vectors, not before.    
        !           133: 
        !           134: Wed Sep 26 12:51:05 EDT 1990   Jay Fenlason ([email protected])
        !           135: 
        !           136:        * gprof.c  When closing /dev/kmem, use fclose instead of ck_fclose
        !           137:        because some systems erroniously return NOT_OWNER on close. . .
        !           138: 
        !           139: Mon Sep  3 18:14:35 1990  Mike Haertel  (mike at wookumz.ai.mit.edu)
        !           140: 
        !           141:        * ar.c (insert_in_map): Always insert __.SYMDEF at the front
        !           142:        of the archive.
        !           143: 
        !           144: Mon Aug 13 19:01:27 1990  Chris Hanson  (cph at kleph)
        !           145: 
        !           146:        * ranlib.c (main): Remove emulation of `psignal' from last
        !           147:        change.  There is already an emulation that was accidentally
        !           148:        omitted from the last release.
        !           149: 
        !           150: Thu Aug  9 13:57:53 1990  Chris Hanson  (cph at kleph)
        !           151: 
        !           152:        * hp-bin/ioutil.c (iou_open): Remove external declaration of
        !           153:        `open', which conflicts with that supplied in hp-ux 7.0.
        !           154: 
        !           155:        * hp-bin/hpxt.c: Add compile-time test that signals an error
        !           156:        if this file is compiled on the wrong kind of machine.
        !           157: 
        !           158:        * nm.c (getpagesize): Add emulation for USG machines.  This is
        !           159:        needed for GNU malloc, and perhaps should be placed there
        !           160:        instead.
        !           161: 
        !           162:        * strip.c, ar.c: Make conditionalization of BSD features be
        !           163:        more selective.  Previously these features were not used if
        !           164:        USG was defined -- but HP-UX supports them.
        !           165: 
        !           166:        * ranlib.c (main): Add emulation of `psignal' for USG
        !           167:        machines.
        !           168: 
        !           169: Tue Jul 10 02:07:08 1990  David J. MacKenzie  (djm at apple-gunkies)
        !           170: 
        !           171:        * ar.c: Remove unused variables.
        !           172:        (copy_out_member): Declare `outname' as char *.
        !           173:        Use `program_name' instead of hardcoded "ar" in messages.
        !           174: 
        !           175:        * robotussin.c: Use `program_name' instead of hardcoded
        !           176:        "robotussin" in messages.
        !           177: 
        !           178:        * objdump.c: Indent.  Declare a lot of functions void.
        !           179:        Improve comments.  Rename option variables to reflect their
        !           180:        meanings rather than the short option names.
        !           181:        Use error instead of fprintf and perror.  Include filename in messages.
        !           182:        (main): Exit with 0 status normally.  Change +reloc to +relocation.
        !           183:        (dump_file): Renamed from doit.
        !           184:        (dump_reloc1): Do nothing if sun and sparc (structure isn't defined).
        !           185:        (getpagesize): Add emulations for USG and sparc, copied from ld.c.
        !           186: 
        !           187:        * size.c: Declare some functions void.  Use `program_name'
        !           188:        instead of hardcoded "size" in messages.
        !           189: 
        !           190:        * gprof.c, robotussin.c: Use VPRINTF_MISSING, to be consistent
        !           191:        with error.c.
        !           192: 
        !           193:        * nm.c: Declare some functions void.  Remove unused variables.
        !           194: 
        !           195:        * strip.c: Declare some functions void.
        !           196:        Make `strip_symbols' and `discard_locals' enums instead of ints.
        !           197:        Remove unused variables.
        !           198:        (fatal, error_with_file, usage): Use `program_name' instead of

                   1228:        * ld.c: Added #ifndef sony_news around inclusion of fcntl.h.  This

                   1231:        * nm.c: Added include of alloca.h on a sun4 and use of

                   1251:        (which is what we want, since we are concerned with symbol
                   1252:        definitions).
                   1253: 
                   1254:        * ld.c: Added a parameter MAX_ALIGNMENT, defined in #ifdef sparc
                   1255:        and by default, to set the maximum necessary alignment for data
                   1256:        objects on this machine.  This is necessary for allocation in the

                   1258:        (digest_symbols): Made sure that everything allocated had the

                   1260:        MAX_ALIGNMENT.

                   1265: 
                   1266:        * ar.c (rename for USG): ignore error from first unlink

                   1273:        * ld.c(next_debug_entry): Mask n_type field in switch statement
                   1274:        since it is a char, and some of its values (N_SOL) are > 128, which
                   1275:        get sign extended on some machines.
                   1276: 
                   1277:        * objdump.c: Deal with symbols that have no name; mask fields

                   1283:        being copied, that N_INDR symbols were properly followed.  Also
                   1284:        made sure that the symbol indicies were correct even in the
                   1285:        presence of indirection information.
                   1286: 
                   1287:        * ld.c (write_rel): When specifying symbol numbers, make sure to
                   1288:        leave room for the extra undefined ref that will be written for
                   1289:        the sake of N_INDR entries.
                   1290: 
                   1291:        * ld.c (write_syms): Fixed typo; a duplicate of the N_INDR entry
                   1292:        was being written instead of the undefined ref required.

                   1316:        set to zero (either on a free or a function return if space had

                   1320:        taken care of when compiling on hpux because of define of USG in

                   1325:        * strip.c (strip_file): Effectively defer certain signals

                   1330:        * These changes improve support for COFF_ENCAPSULATE, and
                   1331:        for the future development of the GNU exec header.  The
                   1332:        main change is to rename the exec header field a_magic
                   1333:        so that it can contain additional information.  Now, the
                   1334:        magic number must be accessed with N_MAGIC(exec), and set
                   1335:        with N_SET_MAGIC(exec,val).  Programs that only need to use
                   1336:        N_BADMAG will not have to change.  Also COFF_ENCAPSULATE will
                   1337:        no longer use "nounderscore", so that it will be more like
                   1338:        normal bsd systems.  This means gcc must be updated before using
                   1339:        these new tools.  (It is safe to put -Dnounderscore back in
                   1340:        if you want to use an old gcc for a while.)
                   1341: 
                   1342:        * README-ENCAP: new documentation for how to set up to use
                   1343:        COFF_ENCAPSULATE.
                   1344: 
                   1345:        * Makefile:  Add target for gnulib.
                   1346:        Don't define 'nounderscore' (must tell gcc about that too.)
                   1347: 
                   1348:        * ar.c: Don't automatically define COFF_ENCAPSULATE.
                   1349: 
                   1350:        * nm.c: No need to initialize the header before reading it.
                   1351: 
                   1352:        * size.c: Include, sys/types.h, and sys/fcntl.h if USG
                   1353:        * strip.c: Likewise--types.h before file.h.
                   1354: 
                   1355:        * ld.c, objdump.c, robotussin.c:
                   1356:        Changed to use new exec macros for a_magic.
                   1357: 
                   1358:        * libconvert: now takes arguments
                   1359: 
                   1360:        * robotussin.c: don't automatically define nounderscore - leave
                   1361:        that to the makefile, if desired
                   1362:

                   1364: 
                   1365:        * ld.c (digest_symbols, write_text, write_data): Changed N_SETV
                   1366:        from being in the text area to being in the data area.
                   1367:        * nm.c, a.out.gnu.h: Changed comments to conform with above.
                   1368: 
                   1369:        * ld.c (do_file_warnings): Added loop to go through each external
                   1370:        nlist entry and check for multiple definitions, as well as
                   1371:        catching any references which weren't caught by the relocation
                   1372:        pass. 
                   1373: 
                   1374:        * ld.c (address_to_line): Changed so that it will work (albeit
                   1375:        slowly) with an address less than the current address.
                   1376:        (do_file_warnings, do_relocation_warnings): Broke out scan through
                   1377:        relocation entries into a separate function.  Added creation of a
                   1378:        bitvector with each bit refereing to an nlist entry so that
                   1379:        do_relocation_warnings could mark which symbol entries it had
                   1380:        output for undefined references.
                   1381:

                   1383: 
                   1384:        * ld.c: Cosmetic changes: Moved helper functions for
                   1385:        do_file_warnings to before it and modified comments to
                   1386:        next_debug_symbol and address_to_line.

                   1412: 
                   1413:        * ld.c: Fixed typo in description of relocation values, and
                   1414:        changed note on RELOC_ADD_EXTRA to force is to be an lvalue if
                   1415:        it's defined.
                   1416:        (coptxtrel): If a specific relocation entry has just changed from
                   1417:        external to internal, and we aren't supposed to add in memory on
                   1418:        the new relocation value, make sure that the value of the symbol
                   1419:        get's added to the ADD_EXTRA in the relocation value.  Otherwise,
                   1420:        all the work we do in a partial linking will be wasted (will be in
                   1421:        memory, but will be ignored on the next pass of the linker).
                   1422:

                   1424: 
                   1425:        * ld.c: Removed "|| TARGET == SUN2" from line 210; I believe that
                   1426:        TARGET and SUN2 were both showing up defined as 0 on the sparc,
                   1427:        which resulted in a redefine of the INITIALIZE_HEADER macro, back
                   1428:        to sun2 style.

                   1431: 
                   1432:        * ld.c, ar.c: Don't define COFF_ENCAPSULATE automatically.
                   1433:        The recommended Makefile change defines it.
                   1434: 
                   1435:        * ld.c (alloca): If compiling with GCC, use __builtin_alloca.
                   1436: 
                   1437:        * robotussin.c: New reformatted version with all variables renamed.
                   1438: 
                   1439:        * ranlib.c: New file, just runs `ar rs' on each specified file.
                   1440:        * Makefile: Special hack to tell ranlib where to find GNU ar.
                   1441:        (LIBS): Recommend -lPW on USG; ld needs it for alloca (if not GCC).
                   1442:

                   1446:        (main): Set `progname' to that name.
                   1447:        (digest_symbols): Fix punctuation and spelling in calls to `error'.
                   1448:

                   1451:        * robotussin.c (INPUT_MAGIC): New macro, has the magic number
                   1452:        to expect in input files.
                   1453:        (nounderscore): New macro; as in ld, define it to inhibit
                   1454:        adding underscore to symbols.
                   1455: 
                   1456:        * Makefile: Don't compile objdump on BSD; N_DATADDR causes trouble.
                   1457: 
                   1458: Tue Dec 20 14:57:38 1988  Pace Willisson  (pace at prep.at.mit.edu)
                   1459: 
                   1460:        * objdump.c: New program like the system 5 'dump' program.
                   1461:        Documentation will follow...
                   1462: 
                   1463:        * Makefile: Set up CFLAGS for USG systems.  Added target
                   1464:        libc.a to do robotussin conversion.  Added objdump.
                   1465: 
                   1466:        * libconvert: Wrote shell script to do robotussin conversion.
                   1467: 
                   1468:        * ar.c, ld.c: Don't define COFF_ENCAPSULATE if it is already defined.
                   1469: 
                   1470:        * ld.c: If i386, set a_machtype to M_386.  Use a_flags instead
                   1471:        of a_encap.  Don't compute coff header if it isn't going to
                   1472:        get written out.
                   1473: 
                   1474:        * robotussin.c: Define COFF_ENCAPSULATE. Include a.out.encap.h
                   1475:        instead of a.out.h.  Check magic number of input
                   1476:        file.  Skip over optional header, if present.  Don't ignore
                   1477:        symbols with aux entries (they could be function definitions),
                   1478:        instead, ignore symbols beginning with '.' (.text, etc).
                   1479:        Don't prepend underscore to externals, since gcc doesn't do
                   1480:        it now.  Don't run past the end of symbols that are exactly
                   1481:        eight characters long.  Always write the string table size,
                   1482:        even if it is empty.  Change relocation types handled from
                   1483:        R_PCRBYTE, etc, to R_DIR32 and R_PCRLONG (these are the
                   1484:        only two emitted by the system 5 assembler.)
                   1485: 
                   1486:        * size.c: Include <sys/types.h> so including sys/file.h will
                   1487:        not get an error on USG systems.  Include fcntl.h on usg systems.
                   1488: 
                   1489:        * strip.c: Move inclusion of file.h to after types.h.  Include
                   1490:        fcntl.h.  Add defintion of rename.
                   1491:

                   1503: 
                   1504:        * strip.c: Change most fatal errors to nonfatal.
                   1505:        (file_open, read_header, read_{file,entry}_symbols):
                   1506:        Now return 0 for success, -1 for failure.
                   1507:        Failure means do no more for the current file.
                   1508:        (modify_relocation): Now just warn if strip a symbol needed
                   1509:        for relocation, and warn only once per file.
                   1510:        (error_with_file): New function, replaces most fatal_with_file.
                   1511:        Print filename first, as in most programs.
                   1512:        (fatal_with_file): Deleted.
                   1513:        (rewrite_file_symbols): Use perror_file when system call fails.
                   1514: 
                   1515: Tue Dec 13 17:16:39 1988  Jay Fenlason  (hack at apple-gunkies.ai.mit.edu)
                   1516: 
                   1517:        * ar.c:  Changed pad character after odd-length archive member
                   1518:        from \0 to \n so archives can be cmp'd with the output from /bin/ar
                   1519:        Added fix for when ranlib is using ar to insert an __.SYMDEF member
                   1520: 
                   1521: Tue Dec 13 09:09:27 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)

                   1539:        Change SYSV conditionals to USG.
                   1540:        Change HEADER_TYPE back to `struct exec'.
                   1541:        (L_SET): Define it if headers don't.
                   1542:        * COFF_ENCAPSULATE conditionals for headers.
                   1543:        (main): Update text_size differently if encapsulating.

                   1550:        * ld.c (do_file_warnings): Ignored text relocation entries that
                   1551:        went through local symbols; any problems with lack of definitions
                   1552:        etc. with them would have been caught by the compiler.
                   1553:

                   1559: 
                   1560:        * ld.c: Put declaration of alloca inside an #ifdef so that it
                   1561:        wouldn't mess up on the sparc.
                   1562: 
                   1563:        * ld.c: Added #define CORE_ADDR for include of symseg.h from gdb
                   1564:        and took out TARGET == SUN2 for sun2 INITIALIZE_HEADER.
                   1565:

                   1567: 
                   1568:        * ld.c: Merged in isi68k port.  This included a kludge for symbols
                   1569:        starting with _$ (#ifdef DOLLAR_KLUDGE) and addition of the
                   1570:        STANDARD_SEARCH_DIRS macro to override the default if it's
                   1571:        defined. 
                   1572: 
                   1573:        * ld.c: Added code for the N_WARNING symbol type.  If a reference
                   1574:        is found to a symbol in an input .o file which contains an
                   1575:        N_WARNING symbol, a warning message (the name of the N_WARNING
                   1576:        symbol) is printed.  This name is treated as a printf format
                   1577:        string; the name of the symbol referenced (which caused the
                   1578:        warning) is supplied as a single argument to the print which
                   1579:        interpets this string.
                   1580:

                   1582: 
                   1583:        * ld.c: Added code for Sun 2.
                   1584: 
                   1585:        * ld.c: Modified access to the relocation information to be *much*
                   1586:        more general; added in sparc support.  This change is a minor
                   1587:        performance hit; the perform_relocation routine uses about 0.1
                   1588:        seconds more time on linking gdb than did the original ld.
                   1589:        (perform_relocation is about 5% of the total time the loader
                   1590:        spends).  The price of generality.
                   1591:

                   1593: 
                   1594:        * Modified ld.c to print only the first 10 unresolved references
                   1595:        for each symbol, followed by a message indicating that there are
                   1596:        more unresolved references that have not been printed (if indeed
                   1597:        there are).  Made default behaivior upon errors *not* writing any
                   1598:        output file at all.  Also added the -noinhibit-exec flag to force
                   1599:        writing of an executable when that was desirable.
                   1600: 
                   1601: Tue Aug  2 12:04:01 1988  Randy Smith  (randy at rice-chex.ai.mit.edu)
                   1602: 
                   1603:        * Modified ld.c to give line numbers wherever possible on
                   1604:        unreferenced symbols.  Added a new symbol (N_DSLNE) to allow for
                   1605:        the same mapping of data location to line number as is done for
                   1606:        text segments by N_SLINE.  Added code to sort the relocation
                   1607:        entries when it is necessary to output these line numbers.  The
                   1608:        assumption was made that both N_SLINE and N_DSLNE symbols would
                   1609:        always be in order by address.

                   1613:        * Modified ld.c to include a facility for equivalencing two
                   1614:        symbols (translating one to another).  Modified lib/a.out.h to
                   1615:        include a definition of this new symbol.  Modified nm.c to
                   1616:        recognize this symbol and all of the set element and vector
                   1617:        symbols I had added before.

                   1620: 
                   1621:        * Modified ld.c to printout source file and line numbers for
                   1622:        unresolved references whenever possible (ie. whenever the input
                   1623:        file has debugger symbols and the reference is from the text area).

                   1627:        * Modified ld.c and a.out.h to handle new types of symbols; the
                   1628:        loader can now create "sets" of symbols from entries in its input
                   1629:        files.  See a.out.h for more info.  Also fixed a bug in ld in
                   1630:        which references to common areas that we not defined in one pass
                   1631:        of the loader caused errors on the next.
