 Get the record keeper that initialized this Init.
const Init * getCastTo (const RecTy *Ty) const override
 If this value is convertible to type Ty, return a value whose type is Ty, generating a !cast operation if required.

 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?
bool isConcrete () const override
 Is this a concrete and fully resolved value without any references or stuck operations?

 Get the string representation of the Init.
Public Member Functions inherited from llvm::Init
InitKind getKind () const
 Get the kind (type) of the value.

 Print this value.
virtual std::string getAsUnquotedString () const
 Convert this value to a literal form, without adding quotes around a string.
void dump () const
 Debugging method that may be called through a debugger; just invokes print on stderr.
virtual const Init * convertInitializerBitRange (ArrayRef< unsigned > Bits) const
 This function is used to implement the bit range selection operator.
virtual const RecTy * getFieldType (const StringInit *FieldName) const
 This function is used to implement the FieldInit class.
virtual const Init * resolveReferences (Resolver &R) const
 This function is used by classes that refer to other variables which may not be defined at the time the expression is formed.

Static Public Member Functions

◆ 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.

References llvm::Init::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 502 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 494 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 489 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 497 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.
