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
getAnUltimateDefinition	Gets a definition that ultimately defines this SSA definition and is not itself a phi node.	from Definition
getBasicBlock	Gets the basic block to which this SSA definition belongs.	from Definition
getFunction	Gets the enclosing declaration of this definition.	from Definition
getIndirection	Gets the indirection of this definition.	from Definition
getIndirectionIndex	Gets the indirection index of this definition.	from Definition
getLocation	Gets the location of this SSA definition.	from Definition
getSourceVariable	Gets the source variable underlying this SSA definition.	from Definition
getUnderlyingType	Gets the underlying type of the variable being defined by this definition.	from Definition
getUnspecifiedType	Gets the unspecified type of the variable being defined by this definition.	from Definition
getValue	INTERNAL: Do not use.	from Definition
