摘要： Systems and methods are disclosed to verify a program by symbolically enumerating path programs; verifying each path program to determine if the path program is correct or leads to a violation of a correctness property; determining a conflict set from the path program if the path program is proved correct; using the conflict set to avoid enumerating other related path programs that are also correct.

摘要： A system and method for infeasible path detection includes performing a static analysis on a program to prove a property of the program. If the property is not proved, infeasible paths in the program are determined by performing a path-insensitive abstract interpretation. Information about such infeasible paths is used to achieve the effects of path-sensitivity in path-insensitive program analysis.

摘要： A computer implemented method for analyzing a computer software program comprising both C++ and C string components, wherein the method includes building a memory model abstraction of any memory used by the program strings. Various memory models are presented that find invalid memory accesses in terms of validity of memory regions and buffer overflows. The model supports analyzing the interaction of C and C++ components—in particular, it focuses on the interaction of C and C++ strings. The conversion of C++ strings to C strings is accomplished through a non-transferable ownership attribute that is to be respected by the C strings. The models can then be analyzed using static analysis techniques such as abstract interpretation and model checking, or through dynamic analysis. In so doing we allow discovery of potential memory safety violations in programs involving conversions between C and C++ strings.
摘要翻译：一种用于分析包括C ++和C字符串组件的计算机软件程序的计算机实现的方法，其中所述方法包括构建由程序串使用的任何存储器的存储器模型抽象。提出了各种存储器模型，它们根据存储器区域和缓冲区溢出的有效性找到无效的存储器访问。该模型支持分析C和C ++组件的交互，特别是C和C ++字符串的交互。将C ++字符串转换为C字符串是通过C字符串要遵守的不可转移的所有权属性来实现的。然后可以使用静态分析技术（如抽象解释和模型检查）或通过动态分析来分析模型。在这样做的时候，我们允许在涉及C和C ++字符串之间的转换的程序中发现潜在的内存安全违规。

摘要： A model is provided for transforming a program with a priori given class hierarchy that is induced by inheritance. An inheritance remover is configured to remove inheritance from a given program to produce an analysis-friendly program which does not include virtual-function pointer tables and runtime libraries associated with inheritance-related operations. The analysis-friendly program preserves the semantics of the given program with respect to a given class hierarchy. A clarifier is configured to identify implicit expressions and function calls and transform the given program into at least one intermediate program having explicit expressions and function calls.

摘要： A system and method for mining program specifications includes generating unit tests to exercise functions of a library through an application program interface (API), based upon an (API) signature. A response to the unit tests is determined to generate a transaction in accordance with a target behavior. The transaction is converted into a relational form, and specifications of the library are learned using an inductive logic programming tool from the relational form of the transaction.
