Abstract
A system and method for facilitating analysis and modification of a computer program. A directed graph is generated from an intermediate language representation of a computer program function, with a node representing each instruction. Meta-edges or meta-nodes are inserted into the directed graph to facilitate location of instruction nodes. One type of meta-edge is a back edge that identifies branch instruction nodes. Some meta-nodes may identify instructions of a specific type. Some meta-nodes may identify exception blocks and corresponding handlers. Analysis of a program function may include insertion of new instructions prior to execution of the function.
