Public Member Functions
VarBitInit (const VarBitInit &)=delete
VarBitInit & operator= (const VarBitInit &)=delete
const Init * getBitVar () const
unsigned getBitNum () const
std::string getAsString () const override
Convert this value to a literal form.
const Init * resolveReferences (Resolver &R) const override
This function is used by classes that refer to other variables which may not be defined at the time the expression is formed.
const Init * getBit (unsigned B) const override
Get the Init value of the specified bit.
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.
const RecTy * getFieldType (const StringInit *FieldName) const override
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.
RecordKeeper & getRecordKeeper () const
Get the record keeper that initialized this Init.
Init (const Init &)=delete
Init & operator= (const Init &)=delete
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?
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.

◆ resolveReferences()

This function is used by classes that refer to other variables which may not be defined at the time the expression is formed.

If a value is set for the variable later, this method will be called on users of the value to allow the value to propagate out.

Reimplemented from llvm::Init.
