void ConstantPointerNull::destroyConstant ( ) [override, 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destroyConstant - Called if some element of this constant is no longer valid.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.

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