The way this pass mapping the control vars and tls vars hasn't consider that there may more than one alias for a tls var. For target supports tls, the code can compile successfully, but the target doesn't support tls will fail. struct __res_state { char x[123]; }; __thread struct __res_state foo; extern __thread struct __res_state bar __attribute__ ((alias ("foo"))); extern __thread struct __res_state baz __attribute__ ((alias ("foo"))); int main() { bar.x[0] = 0; baz.x[1] = 1; return 0; }
