llvm dev - Nov 2017 - How does LLVM map source lines to machine instructions?

Hi all,
How does the flow work in DWARF related LLVM code to map C source lines to
m/c instructions?

My understanding is that clang populates source line numbers to LLVM IR in
some sort of map and backend maps those lines generated m/c instructions
and thus establish the link.
Is that correct?
