摘要： A technique for dynamically relocating an object during garbage collection involves guaranteeing bounds on thread pause times. A process according to the technique may include pausing threads, bounding pause times by scanning only one of a plurality of threads, and resuming the threads. Another process according to the technique may include suspending a plurality o f threads, relocating an object to a new memory location, updating references associated with an old memory location for only one of the threads such that the references are associated with the new memory location, and resuming the threads. In an embodiment, the process may include initially marking each of the threads "unscanned." In another embodiment, the process may include reading the object from the first memory location and writing the object to the second memory location. An example system according to the technique may include a scheduler and a relocation engine. In an embodiment, the scheduler may suspend threads in preparation for dynamic object relocation and then resumes the threads after scanning one, and only one, of the thread stacks. In an embodiment, the thread associated with the scanned thread stack may then be marked "scanned."

摘要： A technique for sharing code fragments involves detecting identical code fragments, then replacing code fragments with references to an identical code fragment. A process according to the technique may include detecting identical code fragments in one or more modules, presenting at runtime a single code fragment that is identical to the identical code fragments, and automatically sharing the single code fragment among the one or more modules. A system according to the technique may include a code fragments database that may includes code fragments and a code server configured to receive requests for a program and provide references to one or more of the code fragments in the code fragments database. Another system according to the technique may include a first object, a second object, and a method object, wherein a reference associated with a first method of the first object and the reference associated with a second method of the second object are pointers to the method object.
摘要翻译：用于共享代码片段的技术涉及检测相同的代码片段，然后用相同代码片段的引用代替代码片段。根据技术的过程可以包括检测一个或多个模块中的相同代码片段，在运行时呈现与相同代码片段相同的单个代码片段，并且在一个或多个模块之间自动共享单个代码片段。根据该技术的系统可以包括可以包括代码片段的代码片段数据库和被配置为接收对程序的请求并提供对代码片段数据库中的一个或多个代码片段的引用的代码服务器。根据该技术的另一系统可以包括第一对象，第二对象和方法对象，其中与第一对象的第一方法相关联的引用和与第二对象的第二方法相关联的引用是指向该方法的指针目的。

摘要： A technique for dynamic dispatch invo lves adapting a method at a dispatch point to reference a state cache. State of the state cache may be associated with an object type and a method signature. When a method is adapted at the dispatch point to reference a state cache, the reference is to a state cache associated with a state that matches the method signature and the object type of the object dispatched upon. The state cache may be shared among multiple methods with similar associated states to reduce memory requirements.
摘要翻译：一种用于动态调度调用的技术适用于调度点处的方法以引用状态高速缓存。状态缓存的状态可以与对象类型和方法签名相关联。当在调度点调整方法以引用状态高速缓存时，引用是与状态相关联的状态缓存，该状态与方法签名和调度的对象的对象类型匹配。可以在具有相似关联状态的多个方法之间共享状态缓存以减少内存需求。
