  • Multiple context software analysis
    Patent number: 6047390
    Abstract: A method for multiple context analysis of software applications in a multiprocessing (22, 23), multithreaded computer environment utilizes instrumentation code inserted (54, 55) into the applications. For each execution (67) of the application (60), a context set is selected (62). Execution of the instrumented code (67) provides information for analysis in an instrumentation buffer (82) addressed by a reserved register (80) or buffer pointer. The operating system is responsible for providing in the reserved register (80) the address of the instrumentation buffer (82) appropriate for each instrumented context executed. When the application (60) is done with an instrumentation buffer (82), the buffer may be processed by filter software (68).
