  23 // This file tests that we correctly deal with weak undefined symbols
  24 // when searching archive libraries.  If we have a weak undefined symbol,
  25 // it should not cause us to link an archive library member that defines
  26 // that symbol.  However, if the symbol is also listed in a -u option on
  27 // the command line, it should cause the archive member to be linked.
