Native code corresponding to an invalidated trace is re-used in a system emulator. A first trace is identified. A dropped second trace is identified. The dropped second trace is associated with a first native code for emulating the second trace. If the identified first trace corresponds to the dropped second trace, the first native code is associated to the first trace, and the first native code is executed. If the identified first trace does not correspond to the dropped second trace, a second native code for emulating the first trace is created, the second native code is associated with the first trace, and the second native code is executed.
