Describes a target addressing mode similar to ExtAddrMode in CodeGenPrepare.
Declared in <llvm/CodeGen/TargetInstrInfo.h>
struct ExtAddrMode;It holds the register values, the scale value and the displacement. It also holds a descriptor for the expression used to calculate the address from the operands.
