Extension of Generic Debugger of the Lissom Project
Hons, Petr ; Husár, Adam (referee) ; Přikryl, Zdeněk (advisor)
This thesis deals with an introduction to debugging and debuggers. The thesis describes principles of the debugging information, especially the DWARF format and its Call Frame Information (CFI), that enables a debugger to visualize the call stack. Furthermore, extensions of the debugger used in the Lissom project were designed and implemented. These extensions added support for call stack visualization, history value storage and step return and step over commands.

Enhancement of Decompilation Results
Končický, Jaromír ; Ďurfina, Lukáš (referee) ; Křoustek, Jakub (advisor)
As a part of the Lissom project, a retargetable decompiler is being developed. Its main purpose is to decompile programs for any particular microprocessor architecture into any high-level programming language. At this thesis's beginning time, its results are not optimal because the decompiler doesn't utilize all program's additional information during decompilation that can improve the results. In this thesis, reverse engineering and Lissom decompiler is described. Techniques of using additional information to enhance decompilation results are proposed. These are data section content analysis and debug information analysis (specifically the debug information in PDB format which is proprietary format). Exploration of internal PDB structure and its content is a part of this thesis. The implementation of data section analysis and debug information utilizing is described and in the end, final decompilation results are discussed.

Retargetable Source-Level Debugger
Korvas, Pavol ; Dolíhal, Luděk (referee) ; Křoustek, Jakub (advisor)
This mater's thesis deals with introducing principles of debugging and debuggers. The thesis examines in detail format of debugging information and it describes the design of debugger created within the project Lissom. Furthermore, the thesis also contains implementation of each designed part, which the debugger consists of. Last part of this thesis deals with testing of the implemented solution with two types of processor architectures and it also contains the conclusion of the results.
