◆ classof()

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

Definition at line 418 of file Record.h.

References I, llvm::Init::IK_FirstTypedInit, and llvm::Init::IK_LastTypedInit.

◆ convertInitializerBitRange()

Init * TypedInit::convertInitializerBitRange ( ArrayRef< unsigned >  Bits) const
overridevirtual

This function is used to implement the bit range selection operator.

Given a value, it selects the specified bits, returning them as a new Init of type bits. If it is not legal to use the bit selection operator on this value, null is returned.

Reimplemented from llvm::Init.

Reimplemented in llvm::IntInit, and llvm::BitsInit.

Definition at line 1627 of file Record.cpp.

References llvm::tgtok::Bit, llvm::tgtok::Bits, llvm::BitsInit::get(), llvm::VarBitInit::get(), getType(), llvm::SmallVectorImpl< T >::reserve(), and T.

◆ convertInitializerTo()

Init * TypedInit::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.

Reimplemented in llvm::DefInit, llvm::ListInit, llvm::StringInit, llvm::IntInit, llvm::BitsInit, and llvm::BitInit.

Definition at line 1616 of file Record.cpp.

References llvm::BitsInit::get(), and getType().

Referenced by getCastTo().

◆ convertInitListSlice()

Init * TypedInit::convertInitListSlice ( ArrayRef< unsigned >  Elements) const
overridevirtual

This function is used to implement the list slice selection operator.

Given a value, it selects the specified list elements, returning them as a new Init of type list. If it is not legal to use the slice operator, null is returned.

Reimplemented from llvm::Init.

Reimplemented in llvm::ListInit.

Definition at line 1661 of file Record.cpp.

References llvm::ListInit::get(), llvm::VarListElementInit::get(), getType(), llvm::SmallVectorImpl< T >::reserve(), llvm::ArrayRef< T >::size(), and T.

◆ getCastTo()

Init * TypedInit::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 1643 of file Record.cpp.

References assert(), llvm::UnOpInit::CAST, convertInitializerTo(), llvm::UnOpInit::Fold(), llvm::UnOpInit::get(), and getType().

◆ getFieldType()

RecTy * TypedInit::getFieldType ( StringInit FieldName) const
overridevirtual

This method is used to implement the FieldInit class.

Implementors of this method should return the type of the named field if they are of type record.

Reimplemented from llvm::Init.

Reimplemented in llvm::DefInit.

Definition at line 1605 of file Record.cpp.
