void ConstantVector::destroyConstant

(

)

[virtual]

destroyConstant - Called if some element of this constant is no longer valid. At this point only other constants may be on the use_list for this constant. Any constants on our Use list must also be destroy'd. The implementation must be sure to remove the constant from the list of available cached constants. Implementations should call destroyConstantImpl as the last thing they do, to destroy all users and delete this.

getSplat - Return a ConstantVector with the specified constant in each element.

Constant * ConstantVector::getSplatValue

(

)

const

getSplatValue - If this is a splat constant, meaning that all of the elements have the same value, return that value. Otherwise return NULL.

getSplatValue - If this is a splat constant, where all of the elements have the same value, return that value. Otherwise return null.

VectorType* llvm::ConstantVector::getType

(

)

const [inline]

getType - Specialize the getType() method to always return a VectorType, which reduces the amount of casting needed in parts of the compiler.

Reimplemented from llvm::Value.

void ConstantVector::replaceUsesOfWithOnConstant	(	Value *	,
		Value *	,
		Use *
	)		[virtual]

replaceUsesOfWithOnConstant - This method is a special form of User::replaceUsesOfWith (which does not work on constants) that does work on constants. Basically this method goes through the trouble of building a new constant that is equivalent to the current one, with all uses of From replaced with uses of To. After this construction is completed, all of the users of 'this' are replaced to use the new constant, and then 'this' is deleted. In general, you should not call this method, instead, use Value::replaceAllUsesWith, which automatically dispatches to this method as needed.
