Public Member Functions inherited from llvm::AbstractState
virtual	~AbstractState ()=default

virtual bool	isValidState () const =0
	Return if this abstract state is in a valid state.

virtual bool	isAtFixpoint () const =0
	Return if this abstract state is fixed, thus does not need to be updated if information changes as it cannot change itself.

virtual ChangeStatus	indicateOptimisticFixpoint ()=0
	Indicate that the abstract state should converge to the optimistic state.

virtual ChangeStatus	indicatePessimisticFixpoint ()=0
	Indicate that the abstract state should converge to the pessimistic state.

Static Public Member Functions

static ValueSimplifyStateType	getWorstState (Type *Ty)
	Return the worst possible representable state.

static ValueSimplifyStateType	getWorstState (const ValueSimplifyStateType &VS)

Protected Member Functions
bool	unionAssumed (std::optional< Value * > Other)
	Merge `Other` into the currently assumed simplified value.

Protected Attributes

	The type of the original value.

BooleanState	BS
	Helper to track validity and fixpoint.

◆ BS

BooleanState llvm::ValueSimplifyStateType::BS

protected

Helper to track validity and fixpoint.

◆ SimplifiedAssociatedValue

std::optional<Value *> llvm::ValueSimplifyStateType::SimplifiedAssociatedValue

protected

An assumed simplified value.

Initially, it is set to std::nullopt, which means that the value is not clear under current assumption. If in the pessimistic state, getAssumedSimplifiedValue doesn't return this value but returns orignal associated value.

◆ Ty

Type* llvm::ValueSimplifyStateType::Ty

protected

The type of the original value.
