source code information in LLVM IR

Hi,

I am generating llvm IR code for C source code using clang as the
front end. I am wondering if there is any way of mapping an llvm IR
line number back to its C source code line number.

Thanks
Sincerely
Arvind

You could use something like:

http://llvm.org/docs/LangRef.html#int_annotation

and just make a lot of it blank. You could also look and see what clang does for line number debug information.
