            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
         Component: ELF
          Assignee: unassignedbugs at nondot.org
          Reporter: rafael.espindola at gmail.com
                CC: llvm-bugs at lists.llvm.org

Given

        .section        .text.bar,"ax", at progbits
        .cfi_startproc
        nop
        .cfi_endproc

        .section        .text.foo,"ax", at progbits
        .cfi_startproc
        nop
        .cfi_endproc

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

gold will merge the .eh_frame entries too.
