Member Function Documentation

◆ classof()

static bool llvm::UnsetInit::classof ( const Init I)
inlinestatic

Definition at line 463 of file Record.h.

References I, and llvm::Init::IK_UnsetInit.

◆ convertInitializerTo()

const Init * UnsetInit::convertInitializerTo ( const RecTy Ty) const
overridevirtual

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.

Implements llvm::Init.

Definition at line 396 of file Record.cpp.

◆ get()

UnsetInit * UnsetInit::get ( RecordKeeper RK)
static

◆ getAsString()

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

Get the string representation of the Init.

Implements llvm::Init.

Definition at line 484 of file Record.h.

◆ getBit()

const Init * llvm::UnsetInit::getBit ( unsigned  Bit) const
inlineoverridevirtual

Get the Init value of the specified bit.

Implements llvm::Init.

Definition at line 476 of file Record.h.

◆ getCastTo()

const Init * UnsetInit::getCastTo ( const RecTy Ty) const
overridevirtual

If this value is convertible to type Ty, return a value whose type is Ty, generating a !cast operation if required.

Otherwise, return null.

Implements llvm::Init.

Definition at line 394 of file Record.cpp.

◆ getRecordKeeper()

RecordKeeper & llvm::UnsetInit::getRecordKeeper ( ) const
inline

Get the record keeper that initialized this Init.

Definition at line 471 of file Record.h.

◆ isComplete()

inlineoverridevirtual

Is this a complete value with no unset (uninitialized) subvalues?

Reimplemented from llvm::Init.

Definition at line 479 of file Record.h.

◆ isConcrete()

bool llvm::UnsetInit::isConcrete ( ) const
inlineoverridevirtual

Is this a concrete and fully resolved value without any references or stuck operations? Unset values are concrete.

Reimplemented from llvm::Init.
