// 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 start two threads, and stop the second one. Then we run the
// first thread through the following cases. Then we let the second
// thread continue, and run it through the same set of cases. All the
// actual thread manipulation is in tls_test_main.cc.
// 1 Access to an uninitialized global thread variable.
// 2 Access to an uninitialized static thread variable.
// 3 Access to an initialized global thread variable.
// 4 Access to an initialized static thread variable.
// 5 Taking the address of a global thread variable.
// 6 Taking the address of a static thread variable.
// 7 Verify that the above tests left the variables set correctly.
