NAME    [Toc]    [Back]

       lorder  -  Finds  the  best  order  for member files in an
       object library

SYNOPSIS    [Toc]    [Back]

       lorder file...

DESCRIPTION    [Toc]    [Back]

       The lorder command is essentially obsolete.  Use the  following
 command in its place: % ar -ts file.a

       The  lorder  command  reads  one or more object or library
       archive files, looks for external references, and writes a
       list of paired filenames to standard output.  The first of
       each pair of files contains references to identifiers that
       are defined in the second file.  You can send this list to
       the tsort command to find an ordering of a library  member
       file suitable for 1-pass access by ld.

       If  object files do not end with lorder overlooks them and
       attributes their global symbols  and  references  to  some
       other file.

EXAMPLES    [Toc]    [Back]

       To  create  a  subroutine  library, enter: lorder charin.o
       scanfld.o scan.o scanln.o |      tsort | xargs ar qv  libsubs.a


       (Enter this command entirely on one line, not on two lines
       as shown above.)

       This creates a subroutine  library  named  libsubs.a  that
       contains  charin.o,  scanfld.o,  scan.o, and scanln.o. The
       ordering of the object modules in the  library  is  important.
  The lorder and tsort commands together add the subroutines
 to the library in the proper order.

       Suppose that scan.o calls entry points  in  scanfld.o  and
       scanln.o.   scanfld.o also calls entry points in charin.o.
       First, the lorder command creates a  list  of  pairs  that
       shows  these  dependencies:  charin.o  charin.o  scanfld.o
       scanfld.o  scan.o  scan.o  scanln.o   scanln.o   scanfld.o
       charin.o scanln.o charin.o scan.o scanfld.o

       This  list  is  piped to the tsort command, which converts
       the list into the ordering that is needed:

       scan.o scanfld.o scanln.o charin.o

       Note that  each  module  precedes  the  module  it  calls.
       charin.o, which does not call another module, is last. The
       second list is then piped to xargs, which  constructs  and
       runs  the  following ar command: ar  qv  libsubs.a  scan.o
       scanfld.o  scanln.o  charin.o

       This ar command creates the properly ordered library.
