05-ranlib-adds-index.sh (634B)

      1 # `kit ranlib` should add a System-V symbol-index member to an
      2 # archive that was created without one. The member list and order
      3 # must be preserved, and the archive must grow (the index member
      4 # adds bytes). Compares pre- and post-ranlib `ar t` output and prints
      5 # whether the archive size strictly increased.
