Hello.

Test case you described should be covered by IPA ICF, where we create a
non-interposable alias of a original symbol that is target of newly created
thunk.

There's -fpic snippet:

_Z8test_barv:
.LFB3:
    .cfi_startproc
    pushq    %rbp
    .cfi_def_cfa_offset 16
    .cfi_offset 6, -16
    movq    %rsp, %rbp
    .cfi_def_cfa_register 6
    call    bar@PLT
    popq    %rbp
    .cfi_def_cfa 7, 8
    ret
    .cfi_endproc
.LFE3:
    .size    _Z8test_barv, .-_Z8test_barv
    .set    _Z8test_barv.localalias.0,_Z8test_barv
    .ident    "GCC: (GNU) 5.0.0 20141209 (experimental)"
    .section    .note.GNU-stack,"",@progbits

But it's probably not enough, what exactly means binds_local_p ?

Thanks,
Martin
