[LLVMdev] Get the filename on which a pass is running?

[Tobias von Koch]

Hi Arnamoy,

Since you're piping the bitcode into opt, there's no way of getting the 
file name because opt just reads from STDIN.

Would it perhaps make more sense to ensure that your bitcode has debug 
information embedded (!dbg metadata) and use that to store a file name?
