Creo 8.0 torrent9/27/2023 ![]() ![]() We show that abstract interpretation of typed lambda calculus programs is complete up to this notion of indistinguishability. Two values (including pairs and functions) are considered indistinguishable if their observable components are indistinguishable. We formulate a weaker notion of completeness based on observability of values. In fact, the notion of completeness used in the first-order case fails if product domains or function spaces are added. Note that products and function spaces over totally ordered domains are not totally ordered. We further generalize these results to typed lambda calculus with pairs and higher-order functions. For such abstract interpretations, we show that the analysis is complete in the sense that, short of actually distinguishing between concrete values with the same abstraction, it gives the best possible information. and Wadler's analysis of list-strictness. This condition is satisfied by Mycroft's strictness analysis that of Sekar et. For the first-order case, we consider abstract interpretations where the abstract domain for data values is totally ordered. We use this approach to characterize a broad class of analysis techniques based on abstract interpretation including, but not limited to, strictness analysis. Their result can be summarized by saying 'strictness analysis is perfect up to variations in constants.' In other words, strictness analysis is as good as it could be, short of actually distinguishing between concrete values. who studied the power of strictness analysis techniques. ![]() Thus, it is important to precisely characterize the power of static analysis techniques. ![]() Often, the failure of the analysis technique to detect some information my mean that the time or space complexity of the generated code would be altered. Increasingly sophisticated applications of static analysis place increased burden on the reliability of the analysis techniques. ![]()
