// 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.
