    • Methods and apparatus for eliminating C recursion from interpreter loops are disclosed. According to one aspect of the present invention, a computer-implemented method for substantially eliminating C recursion from the execution of static initializer methods in a virtual machine environment includes rewriting native C code associated with a static initializer as a Java programming language method, and using a transition frame in a Java programming language stack to execute the Java programming language method. The method also includes using a native method to manipulate the Java programming language stack, and using a first opcode in the transition frame. In one embodiment, using the first opcode in the transition frame includes using the first opcode to determine that the transition frame is associated with the static initializer. In another embodiment, the method further includes causing the static initializer to run, wherein the static initializer using a second opcode, and resuming execution at the second opcode after the static initializer has run.
    • 公开了从解释器循环中消除C递归的方法和装置。 根据本发明的一个方面,用于基本上消除在虚拟机环境中执行静态初始化方法的C递归的计算机实现的方法包括将与静态初始化器相关联的本地C代码重新编程为Java编程语言方法,并且使用 Java编程语言栈中的一个过渡框架来执行Java编程语言方法。 该方法还包括使用本地方法来操纵Java编程语言栈,并且在转换帧中使用第一操作码。 在一个实施例中,在转换帧中使用第一操作码包括使用第一操作码来确定转移帧与静态初始化器相关联。 在另一个实施例中,该方法还包括使静态初始化器运行,其中静态初始化器使用第二操作码,并且在静态初始化器运行之后恢复在第二操作码处的执行。
