jit编译器

• The virtual execution system , including a jit compiler , garbage collector , loader , and threading engine
  虚拟执行系统（ virtual execution system ） ，包括jit编译器、无用单元回收程序、装载器和线程引擎
• Includes two fields that record the settings for whether the jit compiler should optimize , and or generate tracking information
  包括两个字段，这两个字段记录jit编译器是否应优化和/或生成跟踪信息的设置。
• In some cases , you might want to change the behavior of the jit compiler so that the machine code it generates is easier to debug
  在某些情况下，您可能想要更改jit编译器的行为，以便更易于调试它生成的机器码。
• Jit compilers are extremely common for java virtual machines , and they can be used to great effect in emulated virtual machines as well
  Jit编译器对于java虚拟机来说非常常见，这种编译器也可以用于提高仿真虚拟机的效率。
• Object generally a new object each time , and accessed using the accessor method though the jit compiler should inline the access
  对象包装（通常每次都使用新的对象） ，并使用存取方法来访问（虽然jit编译器可能将访问编译成内联函数） 。
• In addition to performance improvements , dynamic methods allow reclamation of the msil method bodies and the related machine code produced by the jit compiler
  除性能改进外，动态方法还允许回收msil方法体和jit编译器产生的相关机器码。
• 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
  您还需要知道jvm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。
• A c compiler could emit a custom modifier to describe how a byte should be treated in cases where the jit compiler treats bytes in manner that is not compatible with c by default
  C + +编译器可发出一个自定义修饰符来说明如何处理字节，以防jit编译器在默认情况下以与c + +不兼容的方式处理字节。
• A c compiler could emit a custom modifier to describe how a byte should be treated in cases where the jit compiler treats bytes in a manner that is not compatible with c by default
  C + +编译器可发出一个自定义修饰符来说明应如何处理字节，以防jit编译器在默认情况下以与c + +不兼容的方式处理字节。
• On the other hand , the run - time environment and jit compiler have more information about what classes are actually loaded , and can make much better optimization decisions than the compiler can
  另一方面，运行时环境和jit编译器拥有更多有关真正装入什么类的信息，可以比编译者作出好得多的优化决定。
