[LLVMdev] IR function pointers

[apala guha]

I am coming up against a lot of function pointers in the IR, although 
the corresponding source code does not have indirect calls.

For example: call void %1608(%"struct.LRT::RGBAucharFrameBuffer"* %1604)

How can I resolve the targets of these? Also, why are they appearing as 
indirect calls in the IR, when they are direct calls in the source?

Thanks.
