Request init/fini array on FreeBSD 12 and later

Authored by emaste on Sep 23 2016, 7:58 AM.



It seems a bad idea to change the default in the middle of a release branch due to possible changes in global ctor / dtor ordering between .ctors and .init_array. With FreeBSD 11.0's release imminent lets change the default now for FreeBSD 12 (the current development stream) and later.

FreeBSD rtld has supported .init_array / .fini_array for many years. As of Jan 1 2017 all supported FreeBSD releases and branches will have support.

Brooks, I can commit this if you prefer. Maybe it can go into 6.0.2 still...

I do think we should make this change, but don't have a strong opinion on the timing. If we do it for 12 and not 13 then we should probably try to get it into a 6.0.2.

I recently made this change for the CHERI clang fork and as far as I can tell everything works fine.

Ping. I'd like this to go in and get merged into FreeBSD's clang so we can test this for a few months before 12.0 branches.
