A system and method for transforming a procedural program having procedural language code into an object-oriented program, comprises scanning the procedural language code and creating a map based on the scanned procedural language code, storing the scanned procedural language code as intermediate code, processing at least a segment of the procedural language code using the map, creating a first data structure using the processed segment, modifying the intermediate code based on the first data structure and generating an object-oriented program having an object class based on the modified intermediate code.

Method and system for transforming legacy software applications into modern object-oriented systems

A system for processing an object specified by an object specifying language such as HTML, JAVA or other languages relying on relative positioning, that require a rendering program utilizing a minimum set of resources, translates the code for use in a target device that has limited processing resources unsuited for storage and execution of the HTML rendering program, JAVA virtual machine, or other rendering engine for the standard. Data concerning such an object is generated by a process that includes first receiving a data set specifying the object according to the object specifying language, translating the first data set into a second data set in an intermediate object language adapted for a second rendering program suitable for rendering by the target device that utilizes actual target display coordinates. The second data set is stored in a machine readable storage device, for later retrieval and execution by the thin client platform.

Methods, systems, and articles of manufacture consistent with the present invention provide a development tool that enables computer programmers to design and develop a data flow program for execution in a multiprocessor computer system. The tool allows the programmer to define a region divided into multiple blocks, wherein each block is associated with data operated on by code segments of the data flow program. The development tool also maintains dependencies among the blocks, each dependency indicating a relationship between two blocks that indicates that the portion of the program associated with a first block of the relationship needs the resultant data provided by the portions of the program associated with a second block of the relationship. The development tool supports several debugging commands, including insertion of multiple types of breakpoints, adding and deleting dependencies, single stepping data flow program execution, and the like.

A computer system for executing a binary image conversion system which converts instructions from a instruction set of a first, non native computer system to a second, different, native computer system, includes an run-time system which in response to a non-native image of an application program written for a non-native instruction set provides an native instruction or a native instruction routine. The run-time system collects profile data in response to execution of the native instructions to determine execution characteristics of the non-native instruction. Thereafter, the non-native instructions and the profile statistics are fed to a binary translator operating in a background mode and which is responsive to the profile data generated by the run-time system to form a translated native image. The run-time system and the binary translator are under the control of a server process. The non-native image is executed in two different enviroments with first portion executed as an interpreted image and remaining portions as a translated image. The run-time system includes an interpreter which is capable of handling condition codes corresponding to the non-native architecute. A technique is also provided to jacket calls between the two execution enviroments and to support object based services. Preferred techniques are also provide to determine interprocedural translation units. Further, intermixed translation/optimization techniques are discussed.

Method and apparatus for dynamic instrumentation of an executable application program. The application program includes a plurality of functions, each function having an entry point and an endpoint. When the application is executed, a shared memory segment is created for an instrumentation program and the application program. Upon initial invocation of the original functions in the application program, corresponding substitute functions are created in the shared memory segment, the substitute versions including instrumentation code. Thereafter, the substitute functions are executed in lieu of the original functions in the application program.
