OpcodeMap maps opcodes to their string descriptions

Functions

func GetOpcodeName

func GetOpcodeName(opcode uint8) (bool, string)

GetOpcodeName returns the string description of an opcode

func GetSuspiciousOpcodes

func GetSuspiciousOpcodes() []uint8

GetSuspiciousOpcodes returns a list of opcodes that might be considered suspicious These are operations that could potentially be used maliciously
