I don't know if this is actually useful for Halo, since this mainly seems to provide source line information for perf samples in JIT'd code. Basically, a human might care about that but not a tool that operates on LLVM IR. If we were able to then use that source-line information to derive the LLVM IR basic blocks belonging to those samples then maybe it would be useful.
