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.

hasMetadata () const

Return true if this value has any metadata attached to it.
