This seems to be enough to avoid naming collisions for functions in any of the current test cases (verified by asserting that the name of the `llvm::Function` matches the name passed to create it - not triggering LLVM's numbering that happens when names collide) It currently implements mangling for namespace scopes, class scopes, and impls. Nothing generic is mangled yet - haven't looked at how that works, though evidently it's not covered by existing testing, I guess. Follow-up change will document the current mangling algorithm in `toolchain/docs/lower.md` --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com> Co-authored-by: Carbon Infra Bot <carbon-external-infra@google.com>
