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