您还需要知道J VM能否确定主机处理器的体系结构，以使得JIT编译器可以为那个体系结构生成正确的指令集。

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.

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。

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.

它使用堆栈体系结构，这意味着在使用指令操作数之前要先将它们装入内部堆栈。

It USES a stack architecture, meaning instruction operands are loaded to an internal stack before they're used.
