Memory model describes the memory consistency requirements in a multithreading system. Compiler optimizations may violate the consistency requirements due to bugs, and the program behavior will differ from the required one. The bugs in compiler optimizations, like incorrect instruction reordering, are very difficult to detect, because they may occur with a very low chance in real execution on a hardware. There are different approaches of formal verification for memory consistency requirements, but the challenge is that the approaches are not scalable for industrial software. In the paper we present the MCC tool that was evaluated on the industrial virtual machine ARK VM and was able to find a real bug in a compiler optimization. The MCC is a static tool, which allows to check all possible executions of a particular test, not relying on a hardware execution. The approach also includes test suite generation and specification of memory consistency properties.
