isNullValue - Return true if this is the value that would be returned by getNullValue. This always returns false because zero structs are always created as ConstantAggregateZero objects.
Implements llvm::Constant.

void ConstantStruct::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destroyConstant - Called if some element of this constant is no longer valid.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.

Referenced by llvm::ConvertConstantType< ConstantStruct, StructType >::convert(), and replaceUsesOfWithOnConstant().
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.
