Modifier and Type	Method	Description
int	getDef()
int	getDef(int i)	Return the ith def
int	getNumberOfDefs()
int	getNumberOfUses()
int	getUse(int j)
boolean	hasDef()	Does this instruction define a normal value, as distinct from a set of exceptions possibly thrown by it (e.g.
int	hashCode()

Methods inherited from class SSAInstruction

copyForSSA, equals, getExceptionTypes, getValueString, iIndex, setInstructionIndex, toString

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.
Collection<TypeReference>	getExceptionTypes()	This method should never return null.
protected String	getValueString(SymbolTable symbolTable, int valueNumber)

Method Details

toString

public String toString(SymbolTable symbolTable)

Specified by:

toString in class SSAInstruction

visit

public void visit(SSAInstruction.IVisitor v)
           throws NullPointerException

Description copied from class: SSAInstruction

Apply an IVisitor to this instruction. We invoke the appropriate IVisitor method according to the type of this instruction.

Specified by:

visit in class SSAInstruction

Throws:

NullPointerException

See Also:

• SSAInstruction.visit(IVisitor)

getOperator

public IBinaryOpInstruction.IOperator getOperator()

Ugh. clean up shrike operator stuff.

isPEI

public boolean isPEI()

Overrides:

isPEI in class SSAInstruction

Returns:

true iff this instruction may throw an exception.

See Also:

• SSAInstruction.isPEI()

isFallThrough

public boolean isFallThrough()

Specified by:

isFallThrough in class SSAInstruction

Returns:

true iff this instruction may fall through to the next

See Also:

• SSAInstruction.isFallThrough()

mayBeIntegerOp

public boolean mayBeIntegerOp()
