            Bug ID: 50975
           Summary: lld/mac is very slow to link lld when debug symbols
                    are present
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: MachO
          Assignee: [email protected]
          Reporter: [email protected]

1. Enable line tables (`-g1`) for building, e.g. with symbol_level=1 in the gn
build
2. Build lld, use lld as host linker

Expected: Fast
Actual: It takes 14 seconds to link lld (compared to 9.5s with ld64).

I can upload a repro file if that's useful (it's 840MB uncompressed).
