            Bug ID: 32175
           Summary: LLD does not recognize -lto_library flag
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: MachO
          Assignee: unassignedbugs at nondot.org

Running macOS with llvm and lld from the git repo.

When compiling using clang -flto, and having a symlink named ld pointing to the
lld binary so that clang will use it for linking, it passes the option
-lto_library to the linker but that makes lld confused, and I get the error:

Unable to find library for -lto_library

PRobably lld should recognize the flag. What is the proper way to use lld on
macOS for LTO ?
