The RV_MARCHID macro is defined using a left shift operation without explicitly specifying the type of the constant. This can lead to undefined behavior, specifically a shift too many bits issue. Modify the RV_MARCHID definition to use the ULL suffix for the constant, ensuring it is treated as an unsigned long long. This eliminates the undefined behavior.
