摘要： Efficient address calculation of invariant reference within a run-time environment is attained by a self-relative numeric reference format for run-time storage of references. A self-relative numeric reference format specifies the location of a reference object relative to a pointer to the referencing object as an integer value. The machine pointers and numeric references may be tagged, and a tag assignment is disclosed so that a self-relative numeric reference is generated from machine pointers by calculating a pointer difference, and a machine pointer to the referenced object is generated by adding the self-relative numeric reference to a machine pointer to the referencing object.

摘要： A static object system is provided to allow for code for implementing a run-time environment to be automatically generated that is compatible with a high-order systems programming language such as C. In particular, the meta-object system is static, object-oriented, and uses generic functions that can dispatch to an appropriate member function based on the types of one or more arguments. In one embodiment, the generated dispatch code uses a multi-way conditional branch.

摘要： Objects that are managed within a run-time environment are stored on N-bit aligned addresses. Due to the alignment restriction, the N least significant bits of a reference to an object are available for storing information about the storage properties of the object. This information is extractable by fast register operations. The storage properties can include the lifetime, format, and contiguity of the object, or a combination of these properties. If the run-time environment implements a generational garbage collector, the reference tags are used to encode whether or not the object is recently allocated.
摘要翻译：在运行时环境中管理的对象存储在N位对齐的地址上。由于对齐限制，对对象的引用的N个最低有效位可用于存储关于对象的存储属性的信息。该信息可以通过快速注册操作来提取。存储属性可以包括对象的生命周期，格式和连续性，或这些属性的组合。如果运行时环境实现代数垃圾收集器，则引用标记用于编码对象是否最近被分配。

摘要： Techniques are provided for instantiating separate Java virtual machines for each session established by a server. Because each session has its own virtual machine, the Java programs executed by the server for each user connected to the server are insulated from the Java programs executed by the server for all other users connected to the server. The separate VM instances can be created and run, for example, in separate units of execution that are managed by the operating system of the platform on which the server is executing. For example, the separate VM instances may be executed either as separate processes, or using separate system threads. Because the units of execution used to run the separate VM instances are provided by the operating system, the operating system is able to ensure that the appropriate degree of insulation exists between the VM instances.

摘要： A method of managing memory mapped input/output (I/O) for a run-time environment is disclosed, in which opaque references are used for accessing information blocks included in files used in a dynamic run-time environment. The information block is stored in a shared memory space of pages that are each aligned on respective boundaries having addresses that are each some multiple of two raised to an integer power. The opaque reference used for the dynamic run-time environment includes at least an index, or page number reference into a page map of references to the pages of the shared memory space, and an offset value indicating an offset into the referenced page for the beginning of the storage of the information block. Control bits of the opaque reference indicate information such as the mapping mode, e.g., read-only, read-write, or private. Pages which are modified by a process may be written back to a backing store of the file based on control bits which indicate that a page has been modified.

摘要： Backtraces are logged in the log file during execution of a program and tagged with information that can categorize the backtraces. Certain tags are also marked as “interesting” in the log file. A report is generated from the log file, indicating which of the backtraces are associated with the tags marked as interesting. In one embodiment, allocations of objects are logged with their addresses, and the objects that are later migrated into session memory are marked interesting.
