            Bug ID: 41077
           Summary: Implement --only-keep-debug for ELF
           Product: tools
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: llvm-objcopy

llvm-objcopy accepts the --only-keep-debug flag, but ignores it for ELF. (COFF
implements it here:
https://github.com/llvm/llvm-project/blob/master/llvm/tools/llvm-objcopy/COFF/COFFObjcopy.cpp#L112)

This supports a common workflow, e.g. as suggested by GNU man pages for
objcopy:

1. clang <...> -o foo
2. llvm-objcopy --only-keep-debug foo foo.dbg
3. llvm-objcopy --strip-debug foo
4. llvm-objcopy --add-gnu-debuglink=foo.dbg foo
