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.
