UnsetInit (const UnsetInit &)=delete | |
UnsetInit & | operator= (const UnsetInit &)=delete |
RecordKeeper & | getRecordKeeper () const |
Get the record keeper that initialized this Init. | |
Init * | getCastTo (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. | |
Init * | convertInitializerTo (RecTy *Ty) const override |
Convert to a value whose type is Ty , or return null if this is not possible. | |
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? Unset values are concrete. | |
std::string | getAsString () const override |
Get the string representation of the Init. | |

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

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.
