Description

VRegOrUnit

Wrapper class representing a virtual register or register unit.

TRI

TargetRegisterInfo base class ‐ We assume that the target defines a static array of TargetRegisterDesc objects that represent all of the machine registers that the target has. As such, we simply have to track a pointer to this array so that we can turn register number into a register descriptor.
