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:
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.
32 // We test the following cases.
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.
40 // 7 Data in file 1 refers to common symbol 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.
46 // 13 Compare address of inline function for equality in both files.
47 // 14 Compare string constants in file 1 and file 2.
48 // 15 Compare wide string constants in file 1 and file 2.
49 // 16 Call a function directly after its address has been taken.
50 // 17 File 1 checks array of string constants defined in file 2.
51 // 18 File 1 checks string constants referenced in code in file 2.
