            Bug ID: 33052
           Summary: -r eats comdats
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: ELF
          Assignee: unassignedbugs at nondot.org

        .globl  _start
 callq foo

        .section        .text.bar,"axG", at progbits,abc,comdat
        .section        .text.foo,"axG", at progbits,xyz,comdat
        .global foo
        mov $60, %rax
        mov $0, %rdi

the produced .o file has two section groups. Passing it to "lld -r" produces a
file with no section groups.
