Member Function Documentation

◆ classof()

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

Definition at line 459 of file Record.h.

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

◆ convertInitializerTo()

Init * UnsetInit::convertInitializerTo ( 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 366 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 482 of file Record.h.

◆ getBit()

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

Get the Init value of the specified bit.

Implements llvm::Init.

Definition at line 472 of file Record.h.

◆ getCastTo()

Init * UnsetInit::getCastTo ( 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 362 of file Record.cpp.

◆ getRecordKeeper()

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

Get the record keeper that initialized this Init.

Definition at line 467 of file Record.h.

◆ isComplete()

bool llvm::UnsetInit::isComplete ( ) const

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

Reimplemented from llvm::Init.

Definition at line 477 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.
