Let us say there is an Instruction I in an IR.
Is there any function using which I can know that in which line number this Instruction I lies in the original c++ file??

Hi,

Let us say there is an Instruction I in an IR.
Is there any function using which I can know that in which line number
this Instruction I lies in the original c++ file??

for this you need to use debug info. It is a frequently asked question
so I suggest you search the mailing list archives.

Ciao,

Duncan.

Try looking at http://llvm.org/docs/SourceLevelDebugging.html; it provides information on the source level debugging metadata in LLVM IR.
