Annotation of researchv10no/cmd/PDP11/11Changelog, revision 1.1

1.1     ! root        1: a.out.h:
        !             2:        Header structure: ints -> unsigned short
        !             3: nm.c:
        !             4:        added static char *progname = argv[0], made error messages
        !             5:        printf(stderr, "%s: ....", progname, ....);  This is because
        !             6:        PDP11-on-VAX system will call it 11nm.  All the other programs
        !             7:        below do this, too.
        !             8:        Added #ifndef A_DOT_OUT lines to default, as always, to "a.out",
        !             9:        but now this is tweakable by the PDP11-on-VAX package. Same is true
        !            10:        for all other programs which use a.out as a file name.
        !            11: ar.c:
        !            12:        Added char *progname = argv[0] for error messages.  On PDP11-on-VAX,
        !            13:        without standard character archiver, ar will be called "car",
        !            14:        character archiver.
        !            15: arcv.c:
        !            16:        same as ar.c above.  Also, sections have #ifdef vax lines which will
        !            17:        fix the reverse longs and use manifest constants instead of sizeof's
        !            18:        in the old binary pdp11-format archive.
        !            19: ld.c:
        !            20:        Slightly overkilled by globally changing all ints into shorts.
        !            21:        char *progname = argv[0]; is used, and added to error messages.
        !            22:        A_DOT_OUT is #defined as "a.out", is tweakable.
        !            23:        One problem overcome was the search path for libraries.  Previously,
        !            24:        a manifest constant string "/usr/lib/libxxxxx..." was used for the
        !            25:        prefix path name;  an fopen was done on this string+4 ("/lib...")
        !            26:        then on string+0 ("/usr/lib...").  This was changed to select
        !            27:        colon-separated names such as the shell PATH variable in a
        !            28:        #define LIBPATH "/lib:/usr/lib"
        !            29:        The reason for this was that the string+4 convention was difficult
        !            30:        to get around portably;  now the PDP11-on-VAX package can tweak this.
        !            31:        It is NOT taken from the environment (by design decision) but can
        !            32:        be replaced by a command option -Lstring, where string specifies
        !            33:        the complete path.
        !            34:        There is also a #define LIBPREFIX "/lib" in there which is
        !            35:        tweakable by the VAX package, which would want "/11lib"
        !            36:        there.  Lib files for the 11 on the vax are prefixed by "11".
        !            37:        The lib file name when selected by the -l option is constructed as:
        !            38:            {an element of LIBPATH} + LIBPREFIX + {-l arg} + ".a"
        !            39: ranlib.c:
        !            40:        ranlib needs to know what the name of the archiver is.  If your
        !            41:        standard system archiver is not char-type (such as USG machines)
        !            42:        then the archiver is called "car"; else the default is "ar".
        !            43:        ranlib also stores progname for error messages.
        !            44: as:
        !            45:        Uses two #define's: A_DOT_OUT "a.out" and PASS2PGM "/lib/as2".
        !            46:        These need to be changed by the PDP11-on-VAX package, but are
        !            47:        the standard as defaults if left alone.
        !            48: c:
        !            49:        No changes by S. Hartwell.  Makefile added.
        !            50: crt:
        !            51:        No changes.  Copied from research; the lmul and ldiv routines
        !            52:        distributed in V7 were buggy.  Note: also includes csav.s
