    • A generalized on-line solution for achieving transparent binary optimization using pre-existing profiling facilities and virtual memory remapping of text regions. An optimization environment is initialized which comprises a debugger program, a profiling facility, and an optimizer. A running target program is attached to the debugger program, wherein the debugger program monitors process execution of the target program. Responsive to monitoring the running target program, profile data of the running target program is collected using the profiling facility. The profile data is provided to the optimizer, wherein the optimizer analyzes the profile data and existing code of the running target program. Responsive to a determination to optimize the existing code based on the profile data, optimized code is generated for the running target program. The optimized code is provided to the debugger program, wherein the debugger program inserts the optimized code into a virtual address space of the running target program.
    • 一种广泛的在线解决方案,用于使用预先存在的分析设施和虚拟内存重新映射文​​本区域来实现透明的二进制优化。 初始化优化环境,其包括调试器程序,分析设备和优化器。 运行的目标程序附加到调试器程序,其中调试程序监视目标程序的进程执行。 响应于监控运行的目标程序,使用分析工具收集运行目标程序的配置文件数据。 简档数据被提供给优化器,其中优化器分析运行目标程序的简档数据和现有代码。 响应于基于简档数据优化现有代码的确定,为运行的目标程序生成优化的代码。 将优化的代码提供给调试器程序,其中调试器程序将优化的代码插入到运行的目标程序的虚拟地址空间中。
