Class Ssa::UncertainDefinition

An SSA definition that represents an uncertain update of the underlying assignable. Either an explicit update that is uncertain (ref assignments need not be certain), an implicit non-local update via a call, or an uncertain update of the qualifier.

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
getAFirstRead	Gets a read of the source variable underlying this SSA definition that can be reached from this SSA definition without passing through any other SSA definition or read. Example:	from Definition
getAFirstReadAtNode	Gets a read of the source variable underlying this SSA definition at control flow node `cfn` that can be reached from this SSA definition without passing through any other SSA definition or read. Example:	from Definition
getALastRead	Gets a last read of the source variable underlying this SSA definition. That is, a read that can reach the end of the enclosing callable, or another SSA definition for the source variable, without passing through any other read. Example:	from Definition
getALastReadAtNode	Gets a last read of the source variable underlying this SSA definition at control flow node `cfn`. That is, a read that can reach the end of the enclosing callable, or another SSA definition for the source variable, without passing through any other read. Example:	from Definition
getARead	Gets a read of the source variable underlying this SSA definition that can be reached from this SSA definition without passing through any other SSA definitions. Example:	from Definition
getAReadAtNode	Gets a read of the source variable underlying this SSA definition at control flow node `cfn` that can be reached from this SSA definition without passing through any other SSA definitions. Example:	from Definition
getAnUltimateDefinition	Gets a definition that ultimately defines this SSA definition and is not itself a phi node. Example:	from Definition
getBasicBlock	Gets the basic block to which this SSA definition belongs.	from Definition
getControlFlowNode	Gets the control flow node of this SSA definition.	from Definition
getElement	Gets the syntax element associated with this SSA definition, if any. This is either an expression, for example `x = 0`, a parameter, or a callable. Phi nodes have no associated syntax element.	from Definition
getEnclosingCallable	Gets the callable to which this SSA definition belongs.	from Definition
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 Definition
isLiveOutRefParameterDefinition	Holds if this SSA definition assigns to `out`/`ref` parameter `p`, and the parameter may remain unchanged throughout the rest of the enclosing callable.	from Definition
toString	Gets a textual representation of this SSA definition.	from Definition
