   4 ## This tests examines the effect of .weak_definition on symbols in an archive
   5 ## that are not referenced directly, but which are still loaded due to some
   6 ## other symbol in the archive member being referenced.
   7 ##
   8 ## In this particular test, _foo isn't referenced directly, but both archives
   9 ## will be fetched when linking against the main test file due to its references
  10 ## to _bar and _baz.
