1.1     ! root        1: Thu Dec 29 01:48:03 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
        !             2: 
        !             3:        * ld.c, ar.c: Don't define COFF_ENCAPSULATE automatically.
        !             4:        The recommended Makefile change defines it.
        !             5: 
        !             6:        * ld.c (alloca): If compiling with GCC, use __builtin_alloca.
        !             7: 
        !             8:        * robotussin.c: New reformatted version with all variables renamed.
        !             9: 
        !            10:        * ranlib.c: New file, just runs `ar rs' on each specified file.
        !            11:        * Makefile: Special hack to tell ranlib where to find GNU ar.
        !            12:        (LIBS): Recommend -lPW on USG; ld needs it for alloca (if not GCC).
        !            13:

        !            15: 
        !            16:        * ld.c (error): Start with name of program running.
        !            17:        (main): Set `progname' to that name.
        !            18:        (digest_symbols): Fix punctuation and spelling in calls to `error'.
        !            19: 
        !            20: Tue Dec 20 21:49:46 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)

        !            22:        * robotussin.c (INPUT_MAGIC): New macro, has the magic number
        !            23:        to expect in input files.
        !            24:        (nounderscore): New macro; as in ld, define it to inhibit
        !            25:        adding underscore to symbols.
        !            26: 
        !            27:        * Makefile: Don't compile objdump on BSD; N_DATADDR causes trouble.
        !            28: 
        !            29: Tue Dec 20 14:57:38 1988  Pace Willisson  (pace at prep.at.mit.edu)

        !            32:        Documentation will follow...
        !            33: 
        !            34:        * Makefile: Set up CFLAGS for USG systems.  Added target
        !            35:        libc.a to do robotussin conversion.  Added objdump.
        !            36: 
        !            37:        * libconvert: Wrote shell script to do robotussin conversion.
        !            38: 
        !            39:        * ar.c, ld.c: Don't define COFF_ENCAPSULATE if it is already defined.
        !            40: 
        !            41:        * ld.c: If i386, set a_machtype to M_386.  Use a_flags instead
        !            42:        of a_encap.  Don't compute coff header if it isn't going to
        !            43:        get written out.
        !            44: 
        !            45:        * robotussin.c: Define COFF_ENCAPSULATE. Include a.out.encap.h
        !            46:        instead of a.out.h.  Check magic number of input
        !            47:        file.  Skip over optional header, if present.  Don't ignore
        !            48:        symbols with aux entries (they could be function definitions),
        !            49:        instead, ignore symbols beginning with '.' (.text, etc).
        !            50:        Don't prepend underscore to externals, since gcc doesn't do
        !            51:        it now.  Don't run past the end of symbols that are exactly
        !            52:        eight characters long.  Always write the string table size,
        !            53:        even if it is empty.  Change relocation types handled from
        !            54:        R_PCRBYTE, etc, to R_DIR32 and R_PCRLONG (these are the
        !            55:        only two emitted by the system 5 assembler.)
        !            56: 
        !            57:        * size.c: Include <sys/types.h> so including sys/file.h will
        !            58:        not get an error on USG systems.  Include fcntl.h on usg systems.
        !            59: 
        !            60:        * strip.c: Move inclusion of file.h to after types.h.  Include
        !            61:        fcntl.h.  Add defintion of rename.
        !            62: 
        !            63: Fri Dec 16 13:55:11 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
        !            64: 
        !            65:        * size.c: Delete all ROBOTUSSIN conditionals and contents.
        !            66:        Change SYSV conditionals to USG.
        !            67:        COFF_ENCAPSULATE conditionals for headers.
        !            68:        (do_one_file, read_header): Skip encapsulation headers if any.
        !            69: 
        !            70:        * strip.c: Delete all ROBOTUSSIN conditionals and contents.
        !            71:        Change SYSV conditionals to USG.
        !            72:        COFF_ENCAPSULATE conditionals for headers.
        !            73:        (file_open, read_header): Skip encapsulation headers if any.
        !            74: 
        !            75:        * strip.c: Change most fatal errors to nonfatal.
        !            76:        (file_open, read_header, read_{file,entry}_symbols):
        !            77:        Now return 0 for success, -1 for failure.
        !            78:        Failure means do no more for the current file.
        !            79:        (modify_relocation): Now just warn if strip a symbol needed
        !            80:        for relocation, and warn only once per file.
        !            81:        (error_with_file): New function, replaces most fatal_with_file.
        !            82:        Print filename first, as in most programs.
        !            83:        (fatal_with_file): Deleted.
        !            84:        (rewrite_file_symbols): Use perror_file when system call fails.
        !            85: 
        !            86: Tue Dec 13 17:16:39 1988  Jay Fenlason  (hack at apple-gunkies.ai.mit.edu)
        !            87: 
        !            88:        * ar.c:  Changed pad character after odd-length archive member
        !            89:        from \0 to \n so archives can be cmp'd with the output from /bin/ar
        !            90:        Added fix for when ranlib is using ar to insert an __.SYMDEF member
        !            91: 
        !            92: Tue Dec 13 09:09:27 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
        !            93: 
        !            94:        * ar.c: conditional #includes for USG.
        !            95:        * COFF_ENCAPSULATE conditionals for headers.

        !            99:        (make_new_symdefs): Skip encapsulation headers if any.
        !           100:        [USG] (bcopy, bzero, bcmp): New fns.
        !           101: 
        !           102:        * nm.c: Delete all ROBOTUSSIN conditionals and contents.
        !           103:        Include types.h.
        !           104:        Change SYSV conditionals to USG.
        !           105:        * COFF_ENCAPSULATE conditionals for headers.
        !           106:        (do_one_file): Skip encapsulation headers if any.
        !           107:        (read_header): Likewise.
        !           108: 
        !           109:        * ld.c: Delete all ROBOTUSSIN conditionals and contents.

        !           111:        Change HEADER_TYPE back to `struct exec'.
        !           112:        (L_SET): Define it if headers don't.
        !           113:        * COFF_ENCAPSULATE conditionals for headers.
        !           114:        (main): Update text_size differently if encapsulating.
        !           115:        (write_header): Write the encapsulation headers if nec.

        !           119: Tue Dec  6 13:26:56 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
        !           120: 
        !           121:        * ld.c (do_file_warnings): Ignored text relocation entries that
        !           122:        went through local symbols; any problems with lack of definitions
        !           123:        etc. with them would have been caught by the compiler.
        !           124: 
        !           125: Mon Dec  5 16:13:22 1988  Jay Fenlason  (hack at sugar-bombs.ai.mit.edu)
        !           126: 
        !           127:        * ar.c (make_new_symdefs): On error, close the input files.
        !           128: 
        !           129: Thu Nov 10 18:15:07 1988  Randall Smith  (randy at apple-gunkies.ai.mit.edu)
        !           130: 
        !           131:        * ld.c: Put declaration of alloca inside an #ifdef so that it
        !           132:        wouldn't mess up on the sparc.
        !           133: 
        !           134:        * ld.c: Added #define CORE_ADDR for include of symseg.h from gdb
        !           135:        and took out TARGET == SUN2 for sun2 INITIALIZE_HEADER.
        !           136: 
        !           137: Wed Nov  2 18:43:09 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
        !           138: 
        !           139:        * ld.c: Merged in isi68k port.  This included a kludge for symbols
        !           140:        starting with _$ (#ifdef DOLLAR_KLUDGE) and addition of the
        !           141:        STANDARD_SEARCH_DIRS macro to override the default if it's
        !           142:        defined. 
        !           143: 
        !           144:        * ld.c: Added code for the N_WARNING symbol type.  If a reference
        !           145:        is found to a symbol in an input .o file which contains an
        !           146:        N_WARNING symbol, a warning message (the name of the N_WARNING
        !           147:        symbol) is printed.  This name is treated as a printf format
        !           148:        string; the name of the symbol referenced (which caused the
        !           149:        warning) is supplied as a single argument to the print which
        !           150:        interpets this string.
        !           151: 
        !           152: Tue Nov  1 16:57:00 1988  Randall Smith  (randy at gluteus.ai.mit.edu)
        !           153: 
        !           154:        * ld.c: Added code for Sun 2.
        !           155: 
        !           156:        * ld.c: Modified access to the relocation information to be *much*
        !           157:        more general; added in sparc support.  This change is a minor
        !           158:        performance hit; the perform_relocation routine uses about 0.1
        !           159:        seconds more time on linking gdb than did the original ld.
        !           160:        (perform_relocation is about 5% of the total time the loader
        !           161:        spends).  The price of generality.
        !           162: 
        !           163: Thu Aug  4 13:20:50 1988  Randy Smith  (randy at rice-chex.ai.mit.edu)
        !           164: 
        !           165:        * Modified ld.c to print only the first 10 unresolved references
        !           166:        for each symbol, followed by a message indicating that there are
        !           167:        more unresolved references that have not been printed (if indeed
        !           168:        there are).  Made default behaivior upon errors *not* writing any
        !           169:        output file at all.  Also added the -noinhibit-exec flag to force
        !           170:        writing of an executable when that was desirable.
        !           171: 
        !           172: Tue Aug  2 12:04:01 1988  Randy Smith  (randy at rice-chex.ai.mit.edu)
        !           173: 
        !           174:        * Modified ld.c to give line numbers wherever possible on
        !           175:        unreferenced symbols.  Added a new symbol (N_DSLNE) to allow for
        !           176:        the same mapping of data location to line number as is done for
        !           177:        text segments by N_SLINE.  Added code to sort the relocation
        !           178:        entries when it is necessary to output these line numbers.  The
        !           179:        assumption was made that both N_SLINE and N_DSLNE symbols would
        !           180:        always be in order by address.
        !           181: 
        !           182: Wed Jul 27 15:13:08 1988  Randy Smith  (randy at rice-chex.ai.mit.edu)
        !           183: 
        !           184:        * Modified ld.c to include a facility for equivalencing two
        !           185:        symbols (translating one to another).  Modified lib/a.out.h to
        !           186:        include a definition of this new symbol.  Modified nm.c to
        !           187:        recognize this symbol and all of the set element and vector
        !           188:        symbols I had added before.
        !           189: 
        !           190: Thu Jul 21 17:06:10 1988  Randy Smith  (randy at rice-chex.ai.mit.edu)
        !           191: 
        !           192:        * Modified ld.c to printout source file and line numbers for
        !           193:        unresolved references whenever possible (ie. whenever the input
        !           194:        file has debugger symbols and the reference is from the text area).
        !           195: 
        !           196: Wed Jul 13 17:21:33 1988  Randy Smith  (randy at frosted-flakes.ai.mit.edu)
        !           197: 
        !           198:        * Modified ld.c and a.out.h to handle new types of symbols; the
        !           199:        loader can now create "sets" of symbols from entries in its input
        !           200:        files.  See a.out.h for more info.  Also fixed a bug in ld in
