llvm dev - Jan 2019 - LLVM CallInst IR to Binary Call Instruction Address Mapping

I have seen this kind of question before, and I believe there isn't any
existing way to get that result.  This is because the LLVM IR is transformed to
Selection DAG, which is transformed to Machine IR, which is then encoded to the
target instruction set and written to the object file. Tracking a particular
CallInst through all that would require a fair amount of additional bookkeeping
information that LLVM does not currently have.

Subject: [llvm-dev] LLVM CallInst IR to Binary Call Instruction Address Mapping

Hi
Good day. I have developed a LLVM IR analysis process (input .bc file) which
returns me a set of llvm::CallInst. Now, I am willing to convert the
llvm::CallInst to its corresponding binary instruction address when the .bc file
will converted to binary (I use llc for this purpose). Any suggestion how could
I achieve this mapping with perfection (in presence of optimization)?
