+// This provides a set of test functions for TLS variables.  The
+// functions are called by a main function in tls_test_main.cc.  This
+// lets us test TLS access from a shared library.  We currently don't
+// bother to test TLS access between two different files, on the
+// theory that that is no more complicated than ordinary variable
+// access between files.
+
+// We test that we correctly deal with weak symbols defined in
+// other libraries (in this case, libc).  We need to make sure we
+// copy the associated GLOBAL reloc when we copy a WEAK reloc.
