Instrumentation of C/C++ Programs during Compilation
Mušková, Kateřina ; Peringer, Petr (referee) ; Smrčka, Aleš (advisor)
This thesis presents design and implementation of the TforcTool offering compile-time instrumentation of memory access and functions. The tool is built on an existing static instrumenting tool Tforc, which was extended in order to provide greater usability and functionality. The advantage of this solution compared to another compile-time tools is that there is no need to change current compile structure of project.

Development of Instrumentation during Compilation
Ševčík, Václav ; Peringer, Petr (referee) ; Smrčka, Aleš (advisor)
The focus of this master's thesis is on the topic of instrumentation during the compilation process in the LLVM compiler. The tool enables to instrument memory accesses and functions. The instrumentation is realized through adding a novel pass to the LLVM's optimalization phase. Information about variables are managed by the created framework. The framework is linked with the program. The overhead of the instrumentation increases duration of the program by about 14 % in the case of switched off indirect addressing and 23 % in the case of switched on indirect addressing. The main benefit of the work is the possibility of easy instrumentation of the program which can even monitor operation of local variables through indirect addressing) and support multithread programs. The framework is part of Testos's tools where it provides automatic instrumentation in the Spectra tool.
