+// This tests references between files.  This is file 1, and
+// two_file_test_2.cc is file 2.  We test in several different ways:
+
+// Files 1 and 2 linked together in executable.
+// File 1 in executable, file 2 in shared library.
+// File 1 in shared library, file 2 in executable.
+// Files 1 and 2 linked together in shared library.
+// Files 1 and 2 in different shared libraries.
+
+// We test the following cases.
+
+// 1  Code in file 1 calls code in file 2.
+// 2  Code in file 1 refers to global data in file 2.
+// 3  Code in file 1 referes to common symbol in file 2.
+// 4  Code in file 1 refers to offset within global data in file 2.
+// 5  Code in file 1 refers to offset within common symbol in file 2.
+// 6  Data in file 1 refers to global data in file 2.
+// 7  Data in file 1 refers to common symbol in file 2.
+// 8  Data in file 1 refers to offset within global data in file 2.
+// 9  Data in file 1 refers to offset within common symbol in file 2.
+// 10 Data in file 1 refers to function in file 2.
+// 11 Pass function pointer from file 1 to file 2.
+// 12 Compare address of function for equality in both files.
+// 13 Compare address of inline function for equality in both files.
