We define four different types of X86 operands: register, memory, direct address, and immediate.

Union case	Description
`Label(string, RegType)` Full Usage: `Label(string, RegType)` Parameters: Item1 : `string` Item2 : `RegType`	Label is not encoded in the actual binary. This is only used when we assemble binaries. Item1 : `string` Item2 : `RegType`
`OprDirAddr JumpTarget` Full Usage: `OprDirAddr JumpTarget` Parameters: Item : `JumpTarget`	OprDirAddr is a direct branch target address. Item : `JumpTarget`
`OprImm(int64, OperandSize)` Full Usage: `OprImm(int64, OperandSize)` Parameters: Item1 : `int64` Item2 : `OperandSize`	OprImm represents an immediate operand. The OperandSize here means the size of the encoded immediate value. Item1 : `int64` Item2 : `OperandSize`
`OprMem(Register option, ScaledIndex option, Disp option, OperandSize)` Full Usage: `OprMem(Register option, ScaledIndex option, Disp option, OperandSize)` Parameters: Item1 : `Register option` Item2 : `ScaledIndex option` Item3 : `Disp option` Item4 : `OperandSize`	OprMem represents a memory operand. The OperandSize here means the memory access size of the operand, i.e., how many bytes do we read/write here. Item1 : `Register option` Item2 : `ScaledIndex option` Item3 : `Disp option` Item4 : `OperandSize`
`OprReg Register` Full Usage: `OprReg Register` Parameters: Item : `Register`	A register operand. Item : `Register`
