Functionality (or correctness) of the code describes2 whether thebehavior ofthe recovered code matches the low-levelcode. Theirrecoveredprograms arehard5 to interpret and dissimilar to the source programs. Assembly code may be incorrectly translated into the assembly6 operationsinHLcode. Programaccuracymeasures11 the percentage of recovered programs that preserve both functionality and semantics. We use similar benchmarks as the previous decompiler works [Phoniex28 USENIX'13], including function calls, normal expressions, nested control graphs, variables with different types29 and data dependencies.
