enum llvm::Init::InitKind

protected

Discriminator enum (for isa<>, dyn_cast<>, et al.)

This enum is laid out by a preorder traversal of the inheritance hierarchy, and does not contain an entry for abstract classes, as per the recommendation in docs/HowToSetUpLLVMStyleRTTI.rst.

We also explicitly include "first" and "last" values for each interior node of the inheritance tree, to make it easier to read the corresponding classof().

We could pack these a bit tighter by not having the IK_FirstXXXInit and IK_LastXXXInit be their own values, but that would degrade readability for really no benefit.

Member Function Documentation

virtual Init* llvm::Init::convertInitializerBitRange ( const std::vector< unsigned > & Bits ) const

inlinevirtual

convertInitializerBitRange - This method is used to implement the bitrange selection operator. Given an initializer, it selects the specified bits out, returning them as a new init of bits type. If it is not legal to use the bit subscript operator on this initializer, return null.

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

Definition at line 498 of file Record.h.

virtual Init* llvm::Init::convertInitializerTo ( RecTy * Ty ) const

pure virtual

convertInitializerTo - This virtual function is a simple call-back function that should be overridden to call the appropriate RecTy::convertValue method.

Implemented in llvm::DagInit, llvm::FieldInit, llvm::DefInit, llvm::VarListElementInit, llvm::VarBitInit, llvm::VarInit, llvm::OpInit, llvm::ListInit, llvm::StringInit, llvm::IntInit, llvm::BitsInit, llvm::BitInit, and llvm::UnsetInit.

Referenced by llvm::StringRecTy::convertValue(), llvm::ListRecTy::convertValue(), llvm::DagRecTy::convertValue(), llvm::BinOpInit::Fold(), llvm::TernOpInit::Fold(), llvm::TernOpInit::resolveReferences(), and llvm::RecordVal::setValue().

virtual Init* llvm::Init::convertInitListSlice ( const std::vector< unsigned > & Elements ) const

inlinevirtual

convertInitListSlice - This method is used to implement the list slice selection operator. Given an initializer, it selects the specified list elements, returning them as a new init of list type. If it is not legal to take a slice of this, return null.

Reimplemented in llvm::ListInit, and llvm::TypedInit.

Definition at line 508 of file Record.h.

void Init::dump ( ) const

dump - Debugging method that may be called through a debugger, just invokes print on stderr.

Definition at line 429 of file Record.cpp.

References llvm::errs(), and print().

virtual std::string llvm::Init::getAsString ( ) const

pure virtual

getAsString - Convert this value to a string form.

Implemented in llvm::DagInit, llvm::FieldInit, llvm::DefInit, llvm::VarListElementInit, llvm::VarBitInit, llvm::VarInit, llvm::TernOpInit, llvm::BinOpInit, llvm::UnOpInit, llvm::ListInit, llvm::StringInit, llvm::IntInit, llvm::BitsInit, llvm::BitInit, and llvm::UnsetInit.

virtual std::string llvm::Init::getAsUnquotedString ( ) const

inlinevirtual

getAsUnquotedString - Convert this value to a string form, without adding quote markers. This primaruly affects StringInits where we will not surround the string value with quotes.

Reimplemented in llvm::StringInit.

Definition at line 480 of file Record.h.

virtual Init* llvm::Init::getBit ( unsigned Bit ) const

pure virtual

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

Implemented in llvm::DagInit, llvm::FieldInit, llvm::DefInit, llvm::VarListElementInit, llvm::VarBitInit, llvm::VarInit, llvm::OpInit, llvm::ListInit, llvm::StringInit, llvm::IntInit, llvm::BitsInit, llvm::BitInit, and llvm::UnsetInit.

Referenced by llvm::BitsInit::resolveReferences(), and llvm::VarBitInit::resolveReferences().

virtual unsigned llvm::Init::getBitNum ( ) const

inlinevirtual

getBitNum - This method is used to retrieve the bit number of a bit reference. For non-VarBitInit, it simply returns 0.

Reimplemented in llvm::VarBitInit.

Definition at line 546 of file Record.h.

Referenced by llvm::BitsInit::resolveReferences().

virtual Init* llvm::Init::getBitVar ( ) const

inlinevirtual

getBitVar - This method is used to retrieve the initializer for bit reference. For non-VarBitInit, it simply returns itself.

virtual Init* llvm::Init::getFieldInit	(	Record &	R,
		const RecordVal *	RV,
		const std::string &	FieldName
	)		const

inlinevirtual

getFieldInit - This method complements getFieldType to return the initializer for the specified field. If getFieldType returns non-null this method should return non-null, otherwise it returns null.

Reimplemented in llvm::DefInit, and llvm::VarInit.

virtual RecTy* llvm::Init::getFieldType ( const std::string & FieldName ) const

inlinevirtual

getFieldType - 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 record type.

Reimplemented in llvm::DefInit, llvm::VarInit, and llvm::TypedInit.

		const RecordVal *	RV
	)		const

inlinevirtual

resolveReferences - 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.
