llvm dev - Jun 2010 - [LLVMdev] Casting a Value

Hi,

I have Value V of Type i32*. How can I convert/set it's Type to i32?

Or How can I create another Value of Type i32 and with same name as V.
I have tried

Value *NewV = new Value(Type,scid);
NewV->setName(V->getNameStr());

It causes stack dump. I am not sure as second argument in the Value
constructor as scid (SubClassID). So I have mentioned 0.

Any Idea how to do this?

Regards,
Chayan

You can use the ptrtoint instruction.

Value is an abstract class, you're not supposed to be able to new it
directly.  Please make a subclass.  I'll make the Value ctor protected.
