Abstract: A method and system for creating uniquely representative execution path identifiers of software program. The method comprises the steps of running the software program, continuously accessing execution information of the software program, identifying execution sequences of the execution information, and creating a unique execution path identifier of each of the execution sequences by summing the execution information when the execution information is within a functional boundary thereof so as to create an execution path identifier representing a unique execution sequence of the execution information. The system comprises an execution path identification creator continuously receiving and accessing execution information of the software program, identifying execution sequences of the execution information and creating the unique execution path identifier of each of the execution sequences.

Abstract: A method finds an error in a computer program. A plurality of execution breakpoints are set in the computer program. A portion of the execution of the computer program is simulated as recorded in the trace data in the reverse order until one a plurality of conditions is met, wherein one of the plurality of conditions is an attempt to execute a machine instruction associated with one of the plurality of execution breakpoints.

Abstract: A method finds an error in a computer program. A sequence of machine instructions performed by a processor is recorded as trace data. Further, at least one event is selected from a plurality of events. In addition, an operating system instruction address is determined for the at least one event. Further, at least a portion of the trace data is searched for the operating system instruction address. The execution time for an operating system instruction stored in the operating system instruction address is determined. The execution time is searched through in the database to find task related data. The task related data is displayed.

Abstract: The invention is directed to instrumenting object code of an application and/or an operating system on a target machine so that execution trace data can be generated, collected, and subsequently analyzed for various purposes, such as debugging and performance. Automatic instrumentation may be performed on an application's object code before, during or after linking. A target machine's operating system's object code can be manually or automatically instrumented. By identifying address space switches and thread switches in the operating system's object code, instrumented code can be inserted at locations that enable the execution trace data to be generated. The instrumentation of the operating system and application can enable visibility of total system behavior by enabling generation of trace information sufficient to reconstruct address space switches and context switches.
