delete

Member Function Documentation

◆ classof()

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

Definition at line 446 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 295 of file Record.cpp.

◆ get()

UnsetInit * UnsetInit::get ( )
static

Get the singleton unset Init.

Definition at line 286 of file Record.cpp.

Referenced by llvm::BinOpInit::Fold(), llvm::TernOpInit::Fold(), and llvm::RecordVal::RecordVal().

◆ getAsString()

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

Get the string representation of the Init.

Implements llvm::Init.

Definition at line 466 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 456 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 291 of file Record.cpp.

◆ isComplete()

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

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

Reimplemented from llvm::Init.

Definition at line 461 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.

Definition at line 463 of file Record.h.

◆ operator=()

UnsetInit& llvm::UnsetInit::operator= ( const UnsetInit )
