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?

	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.

virtual	~Init ()=default
virtual bool	isComplete () const
	Is this a complete value with no unset (uninitialized) subvalues?
void	print (raw_ostream &OS) const
	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 *	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.

References I, and llvm::Init::IK_BitInit.

convertInitializerTo()

const Init * BitInit::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.

getAsString()

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

inlineoverridevirtual

Convert this value to a literal form.

Implements llvm::Init.

getBit()

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

inlineoverridevirtual

Get the Init value of the specified bit.

Implements llvm::Init.
