◆ getAsString()

std::string llvm::FieldInit::getAsString ( ) const
inlineoverridevirtual

Convert this value to a string form.

Implements llvm::Init.

Definition at line 1105 of file Record.h.

References llvm::Init::getAsString(), llvm::StringInit::getValue(), and llvm::StringRef::str().

◆ getBit()

Init * FieldInit::getBit ( unsigned  Bit) const
overridevirtual

This method is used to return the initializer for the specified bit.

Implements llvm::Init.

Definition at line 1440 of file Record.cpp.

References llvm::BitRecTy::get(), llvm::VarBitInit::get(), and getType().

◆ operator=()

FieldInit& llvm::FieldInit::operator= ( const FieldInit )
delete

◆ resolveListElementReference()

Init * FieldInit::resolveListElementReference ( Record R,
const RecordVal RV,
unsigned  Elt 
) const
overridevirtual

This method is used to implement VarListElementInit::resolveReferences.

If the list element is resolvable now, we return the resolved value, otherwise we return null.

Implements llvm::TypedInit.

Definition at line 1446 of file Record.cpp.

References E, and llvm::Init::getFieldInit().

◆ resolveReferences()

Init * FieldInit::resolveReferences ( Record R,
const RecordVal RV 
) const
overridevirtual

This method 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.

Definition at line 1462 of file Record.cpp.
