Protected Member Functions inherited from llvm::Value | |
Value (Type *Ty, unsigned scid) | |
~Value () | |
Value's destructor should be virtual by design, but that would require that Value and all of its subclasses have a vtable that effectively duplicates the information in the value ID. | |
void | getAllMetadata (SmallVectorImpl< std::pair< unsigned, MDNode * > > &MDs) const |
Appends all metadata attached to this value to MDs , sorting by KindID. | |
bool | hasMetadata () const |
Return true if this value has any metadata attached to it. | |
bool | eraseMetadata (unsigned KindID) |
Erase all metadata attachments with the given kind. | |
void | eraseMetadataIf (function_ref< bool(unsigned, MDNode *)> Pred) |
Erase all metadata attachments matching the given predicate. | |
void | clearMetadata () |
Erase all metadata attached to this Value. | |
MDNode * | getMetadataImpl (unsigned KindID) const |
Get metadata for the given kind, if any. | |
unsigned short | getSubclassDataFromValue () const |
void | setValueSubclassData (unsigned short D) |

Get the current metadata attachments for the given kind, if any. | |
MDNode * | getMetadata (StringRef Kind) const |
void | getMetadata (unsigned KindID, SmallVectorImpl< MDNode * > &MDs) const |
