llvm dev - Jan 2012 - [LLVMdev] Should the Constant* pointer be declared with "const" or not?

Hi all.
I'm working on patch and I'm using unchangable ConstantInt objects. So 
everywhere I'm using "const ConstantInt*".  But this idea came to 
deadlock after I tried to create ConstantVector using my vector<const 
ConstantInt*> collection. All because of next form of ConstantVector::get:

// Note: ArrayRef declared with non-constant Constant* object.
Constant *ConstantVector::get(ArrayRef<Constant*> V);

What should I do in this case? Make all my ConstantInt* pointers 
non-constant?
