Public Member Functions
	BitInit (const BitInit &)=delete

BitInit &	operator= (BitInit &)=delete

bool	getValue () const

const Init *	convertInitializerTo (const RecTy *Ty) const override
	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	isConcrete () const override
	Is this a concrete and fully resolved value without any references or stuck operations? Unset values are concrete.

std::string	getAsString () const override
	Convert this value to a literal form.

Public Member Functions inherited from llvm::TypedInit
	TypedInit (const TypedInit &)=delete

TypedInit &	operator= (const TypedInit &)=delete

const RecTy *	getType () const
	Get the type of the Init as a RecTy.

RecordKeeper &	getRecordKeeper () const
	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.

const Init *	convertInitializerTo (const RecTy *Ty) const override
	Convert to a value whose type is `Ty`, or return null if this is not possible.

const Init *	convertInitializerBitRange (ArrayRef< unsigned > Bits) const override
	This function is used to implement the bit range selection operator.

	This method is used to implement the FieldInit class.

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

virtual	~Init ()=default

virtual bool	isComplete () const
	Is this a complete value with no unset (uninitialized) subvalues?

virtual bool	isConcrete () const
	Is this a concrete and fully resolved value without any references or stuck operations? Unset values are concrete.

	Print this value.

virtual std::string	getAsString () const =0
	Convert this value to a literal form.

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 *	getCastTo (const RecTy *Ty) const =0
	If this value is convertible to type `Ty`, return a value whose type is `Ty`, generating a !cast operation if required.

virtual const Init *	convertInitializerTo (const RecTy *Ty) const =0
	Convert to a value whose type is `Ty`, or return null if this is not possible.

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.

virtual const Init *	getBit (unsigned Bit) const =0
	Get the `Init` value of the specified bit.
