    • assignAddress

      protected VariableStorage assignAddress(Program program, DataType tp, int[] status, boolean ishiddenret, boolean isindirect)
      Assign next available memory chunk to type
      Parameters:
      program - is the Program
      tp - type being assigned storage
      status - status from previous assignments
      ishiddenret - is true if the parameter is a hidden return value
      isindirect - is true if parameter is really a pointer to the real parameter value
      Returns:
      Address of assigned memory chunk

    • assignMap

      public void assignMap(Program prog, DataType[] proto, ArrayList<VariableStorage> res, boolean addAutoParams)
      Description copied from interface: ParamList

      Specified by:
      assignMap in interface ParamList
      Parameters:
      prog - is the active program
      proto - is the list of datatypes
      res - is the vector for holding the VariableStorage corresponding to datatypes
      addAutoParams - if true add/process auto-parameters

    • getPotentialRegisterStorage

      public VariableStorage[] getPotentialRegisterStorage(Program prog)
      Description copied from interface: ParamList

      Specified by:
      getPotentialRegisterStorage in interface ParamList
      Parameters:
      prog - is the controlling program
      Returns:
      an array of VariableStorage

    • getStackParameterAlignment

      public int getStackParameterAlignment()
      Description copied from interface: ParamList
      Return the amount of alignment used for parameters passed on the stack, or -1 if there are no stack params
      Specified by:
      getStackParameterAlignment in interface ParamList

    • getStackParameterOffset

      public Long getStackParameterOffset()
      Description copied from interface: ParamList
      Find the boundary offset that separates parameters on the stack from other local variables This is usually the address of the first stack parameter, but if the stack grows positive, this is the first address AFTER the parameters on the stack
      Specified by:
      getStackParameterOffset in interface ParamList
      Returns:
      the boundary offset
