MethodReference	getDeclaredTarget()	What method is the declared callee?
int	getDef()
int	getDef(int i)	Return the ith def
int	getException()	Return the value number which is def'fed by this call instruction if the call returns exceptionally.

int	getProgramCounter()
int	getReceiver()
boolean	hasDef()	Does this instruction define a normal value, as distinct from a set of exceptions possibly thrown by it (e.g.
boolean	isDispatch()	Might this call dispatch to one of several possible methods? i.e., in Java, is it an invokeinterface or invokevirtual
boolean	isFallThrough()
boolean	isPEI()
boolean	isSpecial()	Is this a 'special' call? (invokespecial in Java)

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.
int	getNumberOfUses()
