  • Efficient method and apparatus for compiling and linking modules of computer code in a large software system
    Patent number: 5748961
    Abstract: A software system is defined by a tree of system models which are written in a functional language. During a build of the software system, the functions are interpreted and the results of the expensive expressions are cached. Each function is examined before interpretation to see if it has been evaluated before. If a function has already been evaluated, the cached result is retrieved by the evaluator and the time which would have been spent re-evaluating the function is saved.
