A method and apparatus for making flow information available for binary manipulation tasks are disclosed. Flow information is generated and saved either by a compiler or by a flow information generator. A compiler generates the flow information directly from a source file while the compiler is compiling the source file into an executable file. A flow information generator generates the flow information from an executable file in a manner similar to a compiler. Further, the flow information generator groups the executable file into units of text and traces the units to produce the flow information. The binary information thus retrieved is saved and embedded either in a text or a header of the executable file or placed in a file separate from the executable file. The flow information may be used in binary manipulations including binary translations, binary-to-binary optimizations, program tracing, and program debugging.
