    Goblint is a static analyzer, based on abstract interpretation, specializing in multi-threaded C programs. The goal of this thesis is to improve the precision of Goblint's static analysis by enhancing its handling of bit operations. The thesis establishes a set of integer properties that characterize their behaviour when subjected to bitwise operations on their machine representations, which were used to enhance the abstractions of logical bitwise operations in Goblint's integer domains. Additionally, support for the analysis of bit-fields was added. The precision of Goblint's analyses was successfully improved: the implementation was evaluated on SV-COMP benchmarks, resulting in Goblint being able to solve 26 additional tasks, and its correctness was formally proved.
