public class LoadAddrInst
extends LoadInst

A class representing a three-address code load address instruction (LoadAddrInst). A load address instruction consists of a destination variable and a source address (as a String label), which are both inherited from LoadInst. From TACInst it also inherits an opcode (LDADDR).
