2002-04-18 Ulrich Drepper <drepper@redhat.com> * locale/programs/locfile.c (to_archive): New variable. To collect data which has to be added to the locale archive. (write_all_categories): Take new third parameter with locale name. Unless no_archive flag set add new locale data to the archive (write_locale_data): Unless no-archive flag set store generated data in to_archive data structure instead of generation output file. Add new parameter with locale category index. * locale/programs/locfile.h: Add new parameters in declaractions of write_all_categories and write_locale_data. * locale/programs/localedef.c: Recognize --no-archive, --list-archive, --add-to-archive, and --delete-from-archive options. Pass extra parameter to write_all_categories. * locale/programs/localedef.h: Add prototypes for functions in locarchive.c. * locale/locarchive.h: New file. * locale/programs/locarchive.c: New file. * locale/Makefile (distribute): Add programs/locarchive.c and locarchive.h. (localedef-modules): Add md5 and locarchive. Add vpath to crypt subdir for md5.c. * locale/programs/ld-address.c: Pass locale category ID as new second parameter to write_locale_data. * locale/programs/ld-collate.c: Likewise. * locale/programs/ld-ctype.c: Likewise. * locale/programs/ld-identification.c: Likewise. * locale/programs/ld-measurement.c: Likewise. * locale/programs/ld-messages.c: Likewise. * locale/programs/ld-monetary.c: Likewise. * locale/programs/ld-name.c: Likewise. * locale/programs/ld-numeric.c: Likewise. * locale/programs/ld-paper.c: Likewise. * locale/programs/ld-telephone.c: Likewise. * locale/programs/ld-time.c: Likewise. * locale/simple-hash.c: Move compute_hashval function from here... * locale/hashval.h: ...to here. New file. * locale/simple-hash.h: Add prototype for compute_hashval. * include/libintl.h: Minor cleanups. * elf/reldep7.c: New file. * elf/reldep7mod1.c: New file. * elf/reldep7mod2.c: New file. * elf/Makefile: Add rules to build and run reldep7.
