  • Method and apparatus for automatic second-order predictive commoning
    Patent number: 8132163
    Abstract: A method and apparatus for automatic second-order predictive commoning is provided by the present invention. During an analysis phase, the intermediate representation of a program code is analyzed to identify opportunities for second-order predictive commoning optimization. The analyzed information is used by the present invention for apply transformations to the program code, such that the number of memory access and the number of computations are reduced for loop iterations and performance of program code is improved.
    Type: Grant

  • Speculative inlining of overridden methods without using profiling information
    Patent number: 8024720
    Abstract: A computer implemented method, computer usable program code, and a data processing system for selecting a candidate implementation of a virtual overridden method for inlining into a calling method. A determination as to which implementation of a virtual overridden method to inline is made based on its relative “hotness” compared to the other implementations of the same method. The relative hotness can be inferred from the invocation count and sampling count that the virtual machine and the just-in-time compiler already collect for other purposes, that is, without collecting and storing of call-edge profiling information. When a method is being compiled and it is identified that the method contains a call to an overridden method, a candidate for inlining from among the implementations of the overridden method is selected based on relative hotness values. The candidate implementation of the overridden method is then inlined, with a guard, into the calling method.
