// This provides a set of test functions for TLS variables.  The
24
// functions are called by a main function in tls_test_main.cc.  This
25
// lets us test TLS access from a shared library.  We currently don't
26
// bother to test TLS access between two different files, on the
27
// theory that that is no more complicated than ordinary variable
28
// access between files.

// We test that we correctly deal with weak symbols defined in
31
// other libraries (in this case, libc).  We need to make sure we
32
// copy the associated GLOBAL reloc when we copy a WEAK reloc.
