Detailed Description

MCRegisterDesc - This record contains information about a particular register.

The SubRegs field is a zero terminated array of registers that are sub-registers of the specific register, e.g. AL, AH are sub-registers of AX. The SuperRegs field is a zero terminated array of registers that are super-registers of the specific register, e.g. RAX, EAX, are super-registers of AX.
