Predicates

getPriorDefinition

Gets the immediately preceding definition. Since this update is uncertain, the value from the preceding definition might still be valid.

Inherited predicates

definesAt	Holds if this SSA definition defines `v` at index `i` in basic block `bb`. Phi nodes are considered to be at index `-1`, while normal variable writes are at the index of the control flow node they wrap.	from Definition
getARead	Gets a read of this SSA definition.	from SsaDefinition
getAnUltimateDefinition	Gets a definition that ultimately defines this SSA definition and is not itself a phi definition.	from SsaDefinition
getBasicBlock	Gets the basic block to which this SSA definition belongs.	from Definition
getControlFlowNode	Gets the control flow node of this SSA definition.	from SsaDefinition
getLocation	Gets the location of this SSA definition.	from Definition
getSourceVariable	Gets the source variable underlying this SSA definition.	from Definition
isLiveAtEndOfBlock	Holds if this SSA definition is live at the end of basic block `bb`. That is, this definition reaches the end of basic block `bb`, at which point it is still live, without crossing another SSA definition of the same source variable.	from SsaDefinition
toString	Gets a textual representation of this SSA definition.	from SsaDefinition
