An efficient program analysis method is provided for lazily decomposing aggregates (such as records and arrays) into simpler components based on the access patterns specific to a given program. This process allows us both to identify implicit aggregate structure not evident from declarative information in the program, and to simplify the representation of declared aggregates when references are made only to a subset of their components. The method can be exploited to yield: (i) a fast type analysis method applicable to program maintenance applications (such as date usage inference for the Year 2000 problem); and (ii) an efficient method for atomization of aggregates. More specifically, aggregate atomization decomposes all of the data that can be manipulated by the program into a set of disjoint atoms such that each data reference can be modeled as one or more references to atoms without loss of semantic information. Aggregate atomization can be used to adapt program analyses and representations designed for scalar data to aggregate data. In particular, atomization can be used to build more precise versions of program representations such as SSA form or PDGs. Such representations can in turn yield more accurate results for problems such as program slicing. Our techniques are especially useful in weakly-typed languages such as Cobol (where a variable need not be declared as an aggregate to store an aggregate value) and in languages where references to statically-defined sub-ranges of data such as arrays or strings are allowed.

The present invention is directed to providing a higher degree of association between nodes and links in a graph by creating data structures (spiders) that provide views into graphs that transcend the relatively static association of a conventional graph. A spider's variables bind to any number of nodes and links in the graph, enabling all of the bound nodes and links by addressing the spider. By adding constraints on the extent or degree of binding in a spider to a graph, a subset of the graph is identified. The spider can then used to address the subset of the graph as constrained by the spider. A spider can bind to a link in order to identify a parent / child structural subset of the graph. More specifically a spider is a collection of variables that create a template or pattern and bind to the nodes and links in the graph. A spider traverses a graph by binding its variables to various nodes and links in the graph.
