   1 # ignore-cross-compile -- compiling C++ code does not work well when cross-compiling
   2
   3 # This test case makes sure that native libraries are linked with appropriate semantics
   4 # when the `[+-]bundle,[+-]whole-archive` modifiers are applied to them.
   5 #
   6 # The test works by checking that the resulting executables produce the expected output,
   7 # part of which is emitted by otherwise unreferenced C code. If +whole-archive didn't work
   8 # that code would never make it into the final executable and we'd thus be missing some
   9 # of the output.
