Detailed Description

TargetRegisterDesc - This record contains all of the information known about a particular register. The AliasSet field (if not null) contains a pointer to a Zero terminated array of registers that this register aliases. This is needed for architectures like X86 which have AL alias AX alias EAX. Registers that this does not apply to simply should set this to null. 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.
