length指令确定字符串的长度并将其加载到一个整数寄存器中。
The length instruction determines the length of the string and loads it into an integer register.
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.
如果已知锁定是无争用的但是难以避免或删除同步指令，则对这些锁定花费一点小的确定的开销不失为明智的做法。
It can be desirable to have a small and deterministic cost for locking that is known to be uncontested but where synchronization directives are hard to avoid or remove.
