I just tested simple single process/thread console applications and they

Do you have any test case application which would be affected if these
symbols are eliminated?

Generally speaking, all variables that are required to be placed in special sections to take effect,
but are not otherwise referenced, are likely to be affected by LTO, and have to be

Format attributes is interesting issue. Because there are already following
printf implementations:
1) C89 (without %lld) (crtdll.dll, msvcrt10.dll)
2) C89 (without %lld) + MS extensions %I64d (msvcrt20.dll - msvcr110.dll)
