Predicates

getAUse	Gets an `Operand` that represents a use of this definition.
getAnIndirectUse	Gets an `Operand` that represents an indirect use of this definition.
getAnUltimateDefinition	Gets a definition that ultimately defines this SSA definition and is not itself a phi node.
getFunction	Gets the enclosing declaration of this definition.
getIndirection	Gets the indirection of this definition.
getIndirectionIndex	Gets the indirection index of this definition.
getUnderlyingType	Gets the underlying type of the variable being defined by this definition.
getUnspecifiedType	Gets the unspecified type of the variable being defined by this definition.
getValue	INTERNAL: Do not use.
isCertain	Holds if this definition is guaranteed to totally overwrite the buffer being written to.
isIndirectParameterDefinition	Holds if this definition defines the `indirectionIndex`’th indirection of parameter `p` upon entry into the enclosing function.
isIndirectThisDefinition	Holds if this definition defines the implicit `*this` parameter (i.e., the indirection of the `this` parameter) upon entry into the enclosing member function.
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.
isParameterDefinition	Holds if this definition defines the parameter `p` upon entry into the enclosing function.
isThisDefinition	Holds if this definition defines the implicit `this` parameter upon entry into the enclosing member function.

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
getBasicBlock	Gets the basic block 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
toString	Gets a textual representation of this SSA definition.	from Definition
