    • A method, executed by a computer, for augmenting a first performance profile with data extracted from a Just-in-Time compiler, the Just-in-Time compiler compiling bytecodes into machine instructions and generating the first performance profile, the bytecodes having an associated original call structure includes: tracking “in-lining” optimizations performed by a Just-in-Time compiler compiling bytecodes into machine instructions; extracting data associated with the tracked “in-lining” optimizations; storing the extracted data in a second profile; and augmenting the first performance profile with the extracted data associated with the tracked “in-lining” optimizations, the extracted data comprising call paths corresponding to the original call structure associated with the bytecodes. A corresponding computer program product and computer system are also disclosed herein.
    • 一种由计算机执行的用于通过从即时编译器提取的数据来扩充第一性能简档的方法,即时编译器将字节码编译成机器指令并生成第一性能配置文件,该字节码具有相关联的 原始呼叫结构包括:跟踪由即时编译器执行的“内联”优化,将字节码编译成机器指令; 提取与跟踪的“内衬”优化相关联的数据; 将所提取的数据存储在第二简档中; 并且利用与跟踪的“内联”优化相关联的提取的数据来扩充第一性能简档,所提取的数据包括与与该字节码相关联的原始呼叫结构对应的呼叫路径。 本文还公开了相应的计算机程序产品和计算机系统。
