StructType * StructType::get	(	const std::vector< const Type * > &	Params,
		bool	isPacked = false
	)			[static]

StructType::get - This static method is the primary way to create a StructType.

Definition at line 1247 of file Type.cpp.

References DOUT.

Referenced by llvm::DIFactory::DIFactory(), get(), llvm::ConstantStruct::get(), llvm::ProgramInfo::getSourceFiles(), and llvm::ProgramInfo::getSourceFunctions().

StructType * StructType::get	(	const Type *	type,
			...
	)			[static]

StructType::get - This static method is a convenience method for creating structure types by specifying the elements as arguments. Note that this method always returns a non-packed struct. To get an empty struct, pass NULL, NULL.

getTypeAtIndex - Given an index value into the type, return the type of the element. For a structure type, this must be a constant value...

void StructType::refineAbstractType	(	const DerivedType *	OldTy,
		const Type *	NewTy
	)			[virtual]

refineAbstractType - The callback method invoked when an abstract type is resolved to another type. An object must override this method to update its internal state to reference NewType instead of OldType.

Reimplemented from llvm::Type.

Definition at line 1495 of file Type.cpp.

void StructType::typeBecameConcrete

(

const DerivedType *

AbsTy

)

[virtual]

The other case which AbstractTypeUsers must be aware of is when a type makes the transition from being abstract (where it has clients on it's AbstractTypeUsers list) to concrete (where it does not). This method notifies ATU's when this occurs for a type.

Reimplemented from llvm::Type.
