Modifier and Type	Method	Description
abstract SSAInstruction	copyForSSA(SSAInstructionFactory insts, int[] defs, int[] uses)	This method is meant to be used during SSA conversion for an IR that is not in SSA form.
final boolean	equals(Object obj)	We assume these instructions are canonical and managed by a governing IR object.
int	getDef()
int	getDef(int i)	Return the ith def
Collection<TypeReference>	getExceptionTypes()	This method should never return null.
int	getNumberOfDefs()
int	getNumberOfUses()
int	getUse(int j)
protected String	getValueString(SymbolTable symbolTable, int valueNumber)
boolean	hasDef()	Does this instruction define a normal value, as distinct from a set of exceptions possibly thrown by it (e.g.
abstract int	hashCode()
int	iIndex()
abstract boolean	isFallThrough()
void	setInstructionIndex(int instructionIndex)
String	toString()
abstract String	toString(SymbolTable symbolTable)
abstract void	visit(SSAInstruction.IVisitor v)	Apply an IVisitor to this instruction.
