VectorType * VectorType::get	(	const Type *	ElementType,
		unsigned	NumElements
	)			[static]

static VectorType* llvm::VectorType::getInteger

(

const VectorType *

VTy

)

[inline, static]

VectorType::getInteger - This static method gets a VectorType with the same number of elements as the input type, and the element type is an integer type of the same width as the input element type.

static VectorType* llvm::VectorType::getExtendedElementVectorType

(

const VectorType *

VTy

)

[inline, static]

VectorType::getExtendedElementVectorType - This static method is like getInteger except that the element types are twice as wide as the elements in the input type.

Definition at line 376 of file DerivedTypes.h.

static VectorType* llvm::VectorType::getTruncatedElementVectorType

(

const VectorType *

VTy

)

[inline, static]

VectorType::getTruncatedElementVectorType - This static method is like getInteger except that the element types are half as wide as the elements in the input type.

Definition at line 386 of file DerivedTypes.h.

void VectorType::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 1482 of file Type.cpp.

void VectorType::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.

Definition at line 1487 of file Type.cpp.

[inline, static]

Methods for support type inquiry through isa, cast, and dyn_cast:.
