US Patent 9223554 Recovering source code structure from program binaries

Recovering structure from binaries is disclosed. A binary file having components including a plurality of linker objects is received. A cross reference map of linker objects is created. The linker objects are associated based on calls. An address space distance for each call is determined. Boundaries are defined in the cross reference map based on the address space distance. Subsets are defined as portions of the file that are separated by the boundaries.
