| ; that the only error produced by the JIT for a thread-local with emulated-tls |
| ; enabled is a missing symbol error for __emutls_get_address. An unresolved |
| ; reference to this symbol (and only this symbol) implies (1) that the emulated |
| ; tls lowering was applied, and (2) that thread locals defined in the JIT'd code |
