    • A Just-In-Time compiler is provided for use with a virtual machine that executes a virtual machine instruction sequence under the control of a real machine. The compiler converts parts of the virtual machine instruction sequence into the real machine instruction sequence before execution and includes a block start information unit that determines whether the encoded block start information indicates a corresponding virtual machine instruction would correspond to the start of a basic block if the virtual machine instruction sequence was divided into basic blocks. A converting unit converts the virtual machine instructions into real machine instruction sequences and an outputting unit rearranges the real machine instruction sequences from the converting unit into basic blocks in accordance with the block start information. Additionally, the compiler can be enabled by a program stored on a computer readable recording medium.
    • 提供了即时编译器,用于在真机的控制下执行虚拟机指令序列的虚拟机。 编译器在执行之前将虚拟机指令序列的部分转换为实际机器指令序列,并且包括块开始信息单元,其确定编码块开始信息是否指示对应的虚拟机指令将对应于基本块的开始,如果 虚拟机指令序列分为基本块。 A转换单元将虚拟机指令转换为实际机器指令序列,并且输出单元根据块开始信息将来自转换单元的实际机器指令序列重新排列成基本块。 此外,可以通过存储在计算机可读记录介质上的程序启用编译器。
