Method of efficiently performing precise profiling in a multi-threaded dynamic compilation environment
摘要：
Synchronizing clones of a software method to be executed by at least one thread while the software method is compiled. The software method is cloned to generate a software method clone. At least one transition is created between equivalent program points in the software method and the software method clone. A lock object is inserted into one of the software method and the software method clone. Then, code that controls the at least one transition between a profiling clone and a non-profiling clone is changed to access thread-local storage. The non-profiling clone is the one of the software method and the software method clone into which the lock object was inserted. A first synchronization operation is performed at or after an entry point of the non-profiling clone. Then, the profiling clone is executed using thread-local storage.
摘要（中）：

在软件方法被编译的同时，由至少一个线程执行的软件方法的克隆。 克隆软件方法以生成软件方法克隆。 在软件方法中的等效程序点和软件方法克隆之间至少创建一个转换。 将锁定对象插入到软件方法和软件方法克隆之一中。 然后，更改控制概要分析克隆和非概要分析克隆之间的至少一个转换的代码，以访问线程本地存储。 非分析克隆是插入锁定对象的软件方法和软件方法克隆之一。 在非分析克隆的入口点之前或之后执行第一同步操作。 然后，使用线程本地存储执行概要分析克隆。
