Some projects need to prevent reordering of specific top level
declarations with LTO, in particular declarations defining init calls.
The only way to do that with LTO was to use -fno-toplevel-reorder,
which stops reordering for all declarations and makes LTO partitioning
less ef

Isn't that already broken then with -fno-toplevel-reorder?

Actually it seemed like in my tests it only disables unreachable
