- for each opcode and each version, assign corresponding wrapper based on the version and opcodeName - vm/jump_table/ExportInstructionSet: export instruction set attributes based on input version for generating codes, including unsupported instructions of different versions for dummy wrappers - vm/interpreter: if not debug mode, call wrapper instead of execute opcodes directly
- ExportInstructionSet: export instruction set based on input version to json - ImportInstructionSet: import instruction set from json - OpCodeWrapperGenerator: generate wrappers for an instruction set

For each instruction, the interpreter has to check for many details to make proper actions, using some instruction's constants, before executing it. Wrapping the actions and constants needed for each specific instruction reduce the checking time and memory accessing time.
To generate wrappers for a specific version of an instruction set, run the following (version-name is the desired version, if it is not given, all versions will be generated):
