You also need to know whether the JVM correctly determines host processor architecture so that the JIT compiler can produce the correct set of instructions for that architecture.
In order to generate the exact set of the host processor's instructions, the JIT compiler needs to precisely determine the architecture type of the underlying processor.
为了生成主机处理器的正确的指令集，JIT编译器需要明确地确定底层的处理器的体系结构类型。

You may use either a native compiler running under the emulator or a cross-compiler on your host.
