23 | // This tests references between files. This is file 1, and | |
24 | // two_file_test_2.cc is file 2. We test in several different ways: | |
25 | ||
26 | // Files 1 and 2 linked together in executable. | |
27 | // File 1 in executable, file 2 in shared library. | |
28 | // File 1 in shared library, file 2 in executable. | |
29 | // Files 1 and 2 linked together in shared library. | |
30 | // Files 1 and 2 in different shared libraries. | |
31 | ||
32 | // We test the following cases. | |
