[LLVMdev] ReplaceUsesWith

[xli3 at uiuc.edu]

When I try to do this:
  GetElementPtrInst *newIns = new GetElementPtrInst( ... );
  OldIns->ReplaceAllUsesWith( newIns );
 
When I compile the code, it always says, no matching function
for call to `GetElementPtrInst::ReplaceAllUsesWith
(GetElementPtrInst *&)' 

But since GetElementPtrInst is a subclass of Value, why cannot
use this way? What's wrong here?

thanks,
