Thank you.

Usually there's no concept of line number in the in-memory data
structures (.bc is equally valid input and doesn't have lines).

If you run the "debug-ir" pass before yours it'll add Dwarf info to
each instruction, which describes what you want. You can then access
it with Instruction::getDebugLoc.

Cheers.

Tim.
