Class DirectExplicitDefinition

An SSA definition that corresponds to an explicit definition.

Unlike ExplicitDefinition this class does not include indirect explicit definition. See IndirectExplicitDefinition if you want to include those.

from ExplicitDefinition

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
getAUse	Gets an `Operand` that represents a use of this definition.	from Definition
getAnIndirectUse	Gets an `Operand` that represents an indirect use of this definition.	from Definition
getAnUltimateDefinition	Gets a definition that ultimately defines this SSA definition and is not itself a phi node.	from Definition
getAssignedInstruction	Gets the `Instruction` computing the value that is written to the associated SSA variable by this SSA definition.	from ExplicitDefinition
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
isCertain	Holds if this definition is guaranteed to totally overwrite the buffer being written to.	from Definition
isIndirectParameterDefinition	Holds if this definition defines the `indirectionIndex`’th indirection of parameter `p` upon entry into the enclosing function.	from Definition
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.	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
isParameterDefinition	Holds if this definition defines the parameter `p` upon entry into the enclosing function.	from Definition
isThisDefinition	Holds if this definition defines the implicit `this` parameter upon entry into the enclosing member function.	from Definition
toString	Gets a textual representation of this SSA definition.	from Definition
