26 | // This tests references between files. This is file 1, and |
27 | // two_file_test_2.cc is file 2. We test in several different ways: | |

29 | // Files 1 and 2 linked together in executable. | |
30 | // File 1 in executable, file 2 in shared library. | |
31 | // File 1 in shared library, file 2 in executable. | |
32 | // Files 1 and 2 linked together in shared library. | |
33 | // Files 1 and 2 in different shared libraries. | |
