Abstract

This thesis deals with design, implementation and testing of the csim tool, which compares two C source files by their similarity. The primary purpose of this tool is testing of a decompiler developed by AVG Technologies s.r.o. Testing is based on comparing abstract syntax trees of the original and decompiled source files. The reader is introduced to the basics of reverse engineering, especially reverse engineering of a binary file into a high-level programming language source file. The process of compiling followed by decompiling of a file is described along with its effect on reverse engineering. The LLVM project and the Clang compiler is introduced to the reader, since its libraries are the foundation upon which the csim tool is built.

Keywords
