llvm dev - Oct 2011 - [LLVMdev] get Type of SDValue?

Hi,

Once the DAG is built, is there any way to find out what the real type of a
certain SDValue is (Type, not just EVT)?

And as an example, in the XYZTargetLowering::lowerCall method for my target, is
there any way for me to get what Type the SDValue Callee really corrensponds to?

Regards,
Patrik Hägglund

Why do you need this information there?

The calling convention of my target pass pointers, integers and other 
values in different ways so I think I need the Type of each formal 
parameter to be able to correctly determine how to pass each argument.

In case the call is done through a function pointer I thought I could 
pick up those Type:s through the Type of the Callee.
