Markers VM RISC

VM RISC markers are similar to VM markers, they also serve for code virtualization, however, RISC markers provide the maximum protection to the selected code. Apart of classic VM markers, RISC are more complex, heavy and slow. It is not recommended to protect parts of code that are speed sensitive (such as loops) because the execution speed of this code will be reduced in times after protection.
