This paper presents a structuring algorithm for arbitrary reducible, unstructured graphs. Graphs are structured into semantically equivalent graphs, without the need of code replication or introduction of new variables. The algorithm makes use of structures such as, if..then..elses, while, repeat and loop loops, and case statements. Gotos are only used when the graph cannot be structured with any of the above constructs. This algorithm is adequate for the analysis needed in the decompilation of programs, given that a binary program does not contain information as to the language and compiler used to compile the original source program. And given that unstructuredness is introduced by the use of gotos (still widely available in today's compilers) and optimizations produced by the compiler, we have to assume an unstructured graph for our decompilation analysis. This algorithm has been implemented as part of the dcc decompiler, currently under development at the Queensland University of ...
