indicateOptimisticFixpoint()

ChangeStatus llvm::DenormalFPMathState::indicateOptimisticFixpoint ( )

inlineoverridevirtual

Indicate that the abstract state should converge to the optimistic state.

This will usually make the optimistically assumed state the known to be true state.

Returns

ChangeStatus::UNCHANGED as the assumed value should not change.

Implements llvm::AbstractState.

Definition at line 5211 of file Attributor.h.

References indicateFixpoint().

indicatePessimisticFixpoint()

ChangeStatus llvm::DenormalFPMathState::indicatePessimisticFixpoint ( )

inlineoverridevirtual

Indicate that the abstract state should converge to the pessimistic state.

This will usually revert the optimistically assumed state to the known to be true state.

Returns

ChangeStatus::CHANGED as the assumed value may change.

Implements llvm::AbstractState.

Definition at line 5215 of file Attributor.h.

References indicateFixpoint().

isAtFixpoint()

bool llvm::DenormalFPMathState::isAtFixpoint ( ) const

Return if this abstract state is fixed, thus does not need to be updated if information changes as it cannot change itself.

Implements llvm::AbstractState.

isModeFixed()

bool llvm::DenormalFPMathState::isModeFixed ( ) const

Return if this abstract state is in a valid state.

If false, no information provided should be used.
