23 | // This is an alternate version of the source file two_file_test_1.cc, | |
24 | // used to test incremental linking. We build a binary first using this | |
25 | // source file, then do an incremental link with the primary version of | |
26 | // the file. | |
27 | ||
28 | // This tests references between files. This is file 1, and | |
29 | // two_file_test_2.cc is file 2. We test in several different ways: | |
30 | ||
31 | // Files 1 and 2 linked together in executable. | |
32 | // File 1 in executable, file 2 in shared library. | |
33 | // File 1 in shared library, file 2 in executable. | |
34 | // Files 1 and 2 linked together in shared library. | |
35 | // Files 1 and 2 in different shared libraries. | |
36 | ||
37 | // We test the following cases. | |
38 | ||
39 | // 1 Code in file 1 calls code in file 2. | |
40 | // 2 Code in file 1 refers to global data in file 2. | |

44 | // 6 Data in file 1 refers to global data in file 2. | |
45 | // 7 Data in file 1 refers to common symbol in file 2. | |
46 | // 8 Data in file 1 refers to offset within global data in file 2. | |
47 | // 9 Data in file 1 refers to offset within common symbol in file 2. | |
48 | // 10 Data in file 1 refers to function in file 2. | |
49 | // 11 Pass function pointer from file 1 to file 2. | |
50 | // 12 Compare address of function for equality in both files. | |
51 | // 13 Compare address of inline function for equality in both files. | |
52 | // 14 Compare string constants in file 1 and file 2. | |
53 | // 15 Compare wide string constants in file 1 and file 2. | |
54 | // 16 Call a function directly after its address has been taken. | |

56 | // 18 File 1 checks string constants referenced in code in file 2. | |
