Method Detail

getIndex

public int getIndex()

getIndex Get the index number assigned to the symbol. The index number is used in data flow analysis, etc. For ExpId, do not use setIndex but use setLinkedNode. If no index number is assigned to this symbol, return 0.

Returns:

the index number assigned to the symbol.

setIndex

public void setIndex(int pIndex)

setIndex Set the index number assigned to the symbol. The index number is used in data flow analysis, etc. For ExpId, do not use setIndex but use setLinkedNode.

Parameters:

pIndex - index number to be set to this symbol.

resetFlowAnalInf

public void resetFlowAnalInf()

resetFlowAnalInf Reset information for flow analysis, that is, nullify DefUseList, definition list, use list, ExpId, and reset the index value to 0.

getOperandSet

public java.util.Set getOperandSet()

getOperandSet Get the set of operands used in computing the value of this abstract register. The operands are either Var or Reg, excluding Const (Const is not FlowAnalSym).

Returns:

the set of operands.
