A concrete {@link com.oracle.max.cri.ci.CiValue value} is one of the following subclasses: * <ul> * <li>{@link com.oracle.max.cri.ci.CiConstant}: a constant value. * <li>{@link com.oracle.max.cri.ci.CiRegisterValue}: a value stored in a {@linkplain com.oracle.max.cri.ci.CiRegister target machine register}. * <li>{@link com.oracle.max.cri.ci.CiStackSlot}: a spill slot or an outgoing stack-based argument in a method's frame. * <li>{@link com.oracle.max.cri.ci.CiAddress}: an address in target machine memory. * <li>{@link com.oracle.max.graal.compiler.lir.CiVariable}: a value (cf. virtual register) that is yet to be bound to a target machine location (physical register or memory address). *</ul> */ package com.oracle.max.cri.ci;
