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. | |
33 | ||
34 | // 1 Code in file 1 calls code in file 2. | |
35 | // 2 Code in file 1 refers to global data in file 2. | |
36 | // 3 Code in file 1 referes to common symbol in file 2. | |
37 | // 4 Code in file 1 refers to offset within global data in file 2. | |
38 | // 5 Code in file 1 refers to offset within common symbol in file 2. | |
39 | // 6 Data in file 1 refers to global data in file 2. | |

41 | // 8 Data in file 1 refers to offset within global data in file 2. | |
42 | // 9 Data in file 1 refers to offset within common symbol in file 2. | |
43 | // 10 Data in file 1 refers to function in file 2. | |
44 | // 11 Pass function pointer from file 1 to file 2. | |
45 | // 12 Compare address of function for equality in both files. | |
