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. #include <cstdio> int main() { extern char** environ; // defined in libc if (environ == NULL) { fprintf(stderr, "FAILED the environ test: environ is NULL\n"); return 1; } return 0; }
