26 | # The main program defines several symbols with each of the ELF | |
27 | # visibilities, and the shared library attempts to reference the | |
28 | # symbols. We try to link the program and check that the expected | |
29 | # error messages are issued for the references to internal and | |
30 | # hidden symbols. The errors will be found in hidden_test.err. | |
