LLVM Intermediate Representation (IR) is a form used to represent code in a compiler. It is designed to support analysis and transformations usually done in the optimization phase of a compiler. LLVM and its IR provide a good platform for implementation of numerous specialized code analysis tools, such as program crash analysis with coredumps or backtraces, crash security analysis, and SELinux rule analysis.

Goal of the thesis is to implement a service providing an IR representation of C/C++ binaries in Fedora operating system. To ease the implementation of analyzers, the service must provide the IR binaries with all dynamic libraries statically linked. The binaries must contain metadata about code origin and DWARF debugging information. The only way how to run external code from the binary remain system calls, exec, and dlopen.

To provide as many C/C++ binaries as possible in the IR representation, we start by writing an RPM spec file parser, which allow us to alter common build scripts and compilation invocations in RPM spec files. The altered build must use LLVM Clang compiler to generate unoptimized IR files.
