Methods inherited from class SSAInstruction

copyForSSA, equals, getDef, getDef, getExceptionTypes, getNumberOfDefs, getNumberOfUses, getValueString, hasDef, iIndex, isPEI, setInstructionIndex, toString, visit

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()
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.
int	iIndex()
boolean	isPEI()
void	setInstructionIndex(int instructionIndex)
String	toString()
abstract void	visit(SSAInstruction.IVisitor v)	Apply an IVisitor to this instruction.

Method Details

toString

public String toString(SymbolTable symbolTable)

Specified by:

toString in class SSAInstruction

getUse

public int getUse(int j)

Overrides:

getUse in class SSAInstruction

Returns:

value number representing the jth use in this instruction. -1 means TOP (i.e., the value doesn't matter)

Specified by:

hashCode in class SSAInstruction

isFallThrough

public boolean isFallThrough()

Specified by:

isFallThrough in class SSAInstruction

Returns:

true iff this instruction may fall through to the next
