            Bug ID: 34518
           Summary: .eh_frame is not optimized when two sections are ICFed
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P

        .section        .text.bar,"ax", at progbits

        .section        .text.foo,"ax", at progbits

lld will merge the two sections, but .eh_frame will still have two duplicate

gold will merge the .eh_frame entries too.
