	Convert to a value whose type is Ty, or return null if this is not possible.
const Init *	getBit (unsigned Bit) const override
	Get the Init value of the specified bit.
bool	isComplete () const override
	Is this a complete value with no unset (uninitialized) subvalues?

convertInitializerTo()

const Init * UnsetInit::convertInitializerTo ( const RecTy * Ty ) const

overridevirtual

Convert to a value whose type is Ty, or return null if this is not possible.

This can happen if the value's type is convertible to Ty, but there are unresolved references.

Implements llvm::Init.

get()

UnsetInit * UnsetInit::get ( RecordKeeper & RK )

static

Get the singleton unset Init.

getAsString()

std::string llvm::UnsetInit::getAsString ( ) const

inlineoverridevirtual

Get the string representation of the Init.

Implements llvm::Init.

Definition at line 486 of file Record.h.

getBit()

const Init * llvm::UnsetInit::getBit ( unsigned Bit ) const

inlineoverridevirtual

Get the Init value of the specified bit.

Implements llvm::Init.

Definition at line 478 of file Record.h.

References llvm::Init::Init().

getCastTo()

const Init * UnsetInit::getCastTo ( const RecTy * Ty ) const

overridevirtual

If this value is convertible to type Ty, return a value whose type is Ty, generating a !cast operation if required.

Otherwise, return null.

Implements llvm::Init.

getRecordKeeper()

RecordKeeper & llvm::UnsetInit::getRecordKeeper ( ) const

inline

Get the record keeper that initialized this Init.

Definition at line 473 of file Record.h.

isComplete()

bool llvm::UnsetInit::isComplete ( ) const

inlineoverridevirtual

Is this a complete value with no unset (uninitialized) subvalues?

Reimplemented from llvm::Init.

Definition at line 481 of file Record.h.

isConcrete()

bool llvm::UnsetInit::isConcrete ( ) const

inlineoverridevirtual

Is this a concrete and fully resolved value without any references or stuck operations?

Unset values are concrete.
