[LLVMdev] tail call

[reed kotler]

I have a pass which operates on IR for mips16 so that I can build stubs 
and such for floating point.

I usually get this attribute of the call instruction getCalledFunction.

This is turning out to be null when there is a tail call. (I think this 
may be something new but maybe was there already).

So then what is the right way to find the function prototype for the call?

TIA.
