    摘要: The present invention provides a method, apparatus, and computer instructions for dynamic intermediate code transformation in a mixed mode compiler. In an exemplary embodiment, an object code compiler of a virtual-machine, such as the just-in-time (JIT) compiler (415) of a Java virtual machine (JVM), takes loaded classes and compiles these into object code (416). A JIT-enabled dynamic instrumentation (JEDI) interface (420) provides information to an application (e.g., a tool with a GUI), and passes requests for transformation to the JIT (415) and class-loader (410). If loaded, JEDI controls the JIT compiler (415) to compile and transform the class into object code. Thus, dynamically transformed object code is produced without transformation or re-loading of the loaded classes.

    摘要: A method and system to minimize to redundancy in testing a new software system by utilizing a knowledge base is provided. The knowledge base may be represented in a form of a decision tree including leaf nodes which store previously tested optimal configurations. When the knowledge base does not contain an optimal configuration for the new software, an optimal solution for the new software system may be determined by adding a further decision tree branch to the initial decision tree. A desirable tree branch may be selected from a table including a predetermined set of desirable tree branches for each category of software. As a result, the number of solutions to be tested on the input software may be limited and cost and effort to run redundant tests on a software system may be reduced.
