Abstract: The invention relates to a method and apparatus for stack frame elimination for simple procedures with tail calls. Subject to certain prerequisite constraints, the invention modifies the procedure by converting all tail calls to direct branches. The code in the computer program for constructing and deconstructing the stack frame is eliminated. In a preferred embodiment of the invention, dead code elimination is performed on unreachable code. In an alternative, equally preferred embodiment, dead code is retained in the computer program.

Abstract: Systems and methods for implementing an execution stack which stores frames for functions written in multiple programming languages are provided. The frames for functions written in different programming languages may be interleaved on the same execution stack. A data block on the execution stack may be utilized to traverse the execution stack around a frame by storing a stack pointer and frame pointer to a previous frame. Additionally, exceptions may be propagated, with conversion if necessary, through frames on the execution stack that are written in different programming languages.

Abstract: A stack management unit for a processing system that manages multiple stacks and corresponding stack pointer data as a frame stack. The stack management unit utilizes a combination of a primary stack and a secondary stack as the frame stack. A background spill/fill detect unit determines when an overflow/underflow of the primary stack occurs. In response to an overflow/underflow condition, the background spill/fill detect unit controls the transfer of a frame portion between the primary stack and the secondary stack without halting the processing system.

Abstract: A method of producing a computer program for a computer capable of operating in a plurality of disjoint instruction sets. The method produces a plurality of independently callable functions. For each function the method determines a target instruction set employed by the function. The method provides the function with a name corresponding to the target instruction set. The function name is preferably a modification of a user provided function name corresponding to the target instruction set. The method identifies each call of another independent function and provides each with a name corresponding to the target instruction set. The method produces a veneer function for each function and for each other instruction set. The veneer functions include changing the computer from operating in the other instruction set to operating in the target instruction set, calling the corresponding function, changing the computer to operate in the other instruction set, and a return command. Each veneer function is provided with a name corresponding to the other instruction set. Each function and its corresponding veneer functions are converted into a linkable object code module and then linked into an executable object code file of the computer program. The linker preferably omits from the executable object code file any veneer functions not called by a function.

Abstract: A method and apparatus for accelerating the execution of an object oriented computer program having a plurality of objects. In one embodiment, each of the objects includes an object header and object data which are stored in a memory. Moreover, each of the objects is associated with a corresponding set of methods (or functions). A typical object oriented program only maintains one copy of a method which is accessed by more than one object. However, in the present invention, each method is copied and stored in a memory, such that each object has a dedicated set of methods stored in memory. For example, if a first object and a second object require access to the same method, then a first copy of this method is provided for the first object, and a second copy of this method is provided for the second object. Providing each object with a dedicated set of methods minimizes the levels of indirection required to access the methods, and thereby accelerates the execution of instructions which access the objects.

Abstract translation: 一种用于加速具有多个对象的面向对象的计算机程序的执行的方法和装置。 在一个实施例中，每个对象包括存储在存储器中的对象标题和对象数据。 此外，每个对象与一组相应的方法（或功能）相关联。 一个典型的面向对象程序只保存一个由多个对象访问的方法的一个副本。 然而，在本发明中，将每种方法复制并存储在存储器中，使得每个对象具有存储在存储器中的专用方法集合。 例如，如果第一对象和第二对象需要访问相同的方法，则为第一对象提供该方法的第一副本，并且为第二对象提供该方法的第二副本。 通过专门的方法为每个对象提供访问方法所需的间接级别最小化，从而加速访问对象的指令的执行。

Abstract: Apparatus and a related method for managing entities in a complex and, in general, geographically distributed system, such as distributed data processing system. The management approach is defined in terms of a generalized model having management modules integrated into a single cooperative system by a management director kernel. The management modules include presentation modules to provide an interface with users who manage the complex system, access modules to provide an interface with managed entities or devices, and function modules to define various functions that may be performed in controlling or monitoring the managed entities. If the complex system being managed is large, a managed entity and an associated access module may be located on one physical system, while a presentation module is located on another physical system, close to the user, and a function module being used might be located on yet another physical system, for reasons of processing convenience. The present invention provides a convenient mechanism, consistent with the management model, for forwarding procedure calls between management modules located on different physical systems, through management director kernels located on different physical systems. Two types of remote procedure calls are disclosed, one to forward procedure calls for invoking primitive functions, each on a single managed entity, and a more powerful remote procedure call for invoking higher-level functions relating to user-defined domains of multiple managed entities.

Abstract translation: 用于管理复杂和一般地理分布式系统（例如分布式数据处理系统）中的实体的装置和相关方法。 管理方法是根据管理模块将管理模块集成到一个单一的合作系统中，由管理总监内核来定义的。 管理模块包括呈现模块，以提供与管理复杂系统的用户的接口，访问模块以提供与被管理实体或设备的接口以及功能模块，以定义可以在控制或监视被管理实体中执行的各种功能。 如果被管理的复杂系统很大，则被管理实体和相关联的访问模块可以位于一个物理系统上，而呈现模块位于靠近用户的另一物理系统上，并且正在使用的功能模块可能被定位 在另一个物理系统上，出于处理方便的原因。 本发明提供了一种与管理模型一致的方便的机制，用于通过位于不同物理系统上的管理主管内核来转发位于不同物理系统上的管理模块之间的过程调用。 公开了两种类型的远程过程调用，一种用于转发用于调用原始函数的过程调用，每个调用单个被管实体，以及用于调用与多个被管实体的用户定义域相关的更高级功能的更强大的远程过程调用。

Abstract: A program control system in a multitask environment to execute a plurality of programs in parallel. The system includes a program execution control device for controlling an execution of a plurality of programs, a first program and a second program which are mutually related, a subtask execution recognition device for recognizing a subtask execution command in the first program, and a resumption control device for resuming the first program in response to both a wait command in the first program and an end command in the second program of the task associated with the task of the first program. When the subtask execution command is recognized by the subtask execution recognition device while the first program is being executed, the second program is also executed. When the end command in the second program is detected while the first program is in a wait state under the wait command, the resumption control means allows the program execution control means to resume the first program.
