WebThe Java bytecode instructions are fetched from a method cache. The bytecode fetch logic controls the instruction fetching from the same bytecode method according to the program counter values. After fetching all the instructions of a basic block, fetch logic selects the next basic block as predicted by the branch predictor. With WebAbstract. Several techniques for detecting similarities of Java programs from bytecode files, without access to the source, are introduced in this paper. These techniques can be used to compare two files, to find similarities among thousands of files, or to compare one new file to an index of many old ones. right home developers
